As a result, the left and right clamp members 18 _LL and 18 _LR move in association with each other, and the extension drive of the cylinder 9 _L causes the left rollers 22 _LL and 22 _LL to move first in one of the multiple sleeves S. Even if it comes into contact with the side wall S ₃ and stops, the right roller 22 _LR ,
22 _LR further moves to the other side wall S ₃ of the multiple sleeve S.

It is possible to clamp ₃ , ₃ with equal pressure. At this time, the left and right in one cylinder 9 _L roller 22
_{Since LL} , 22 _LL , 22 _LR , and 22 _LR can be driven, the number of parts can be reduced. Support Means M3 As shown in FIGS. 2, 5 and 7, the support means M3 includes lower parts of the left and right side walls S ₃ , S ₃ of the multiple sleeve S (lower parts of the # 1 cylinder and the # 4 cylinder), and multiple supports. Lower central part of the sleeve S (lower part of the connecting portion between the # 2 cylinder and the # 3 cylinder)
And 3 sets are provided in total, and they have substantially the same structure. The structure of the supporting means M3 provided below the # 1 cylinder as a representative thereof will be described below mainly with reference to FIG.

A reference seat 28 that can be brought into contact with the lower end surface S ₂ of the multiple sleeve S is provided on the upper end of the elevating rod 27 that is slidably supported on the base 1 and is biased upward by the weak spring 26. It is provided. A wedge member 30 is provided at the rear end of the guide rod 29 which is guided by the base 1 so as to be slidable back and forth, and which abuts on the lower end of the elevating rod 27. A pressure plate 34 is fixed to an output rod 33 extending rearward from a piston 32 slidably fitted to a cylinder 31 formed on the base 1, and the pressure plate 34 is fixed to the guide rod 2
9 fits loosely. A spring 35 is contracted between the rear surface of the pressing plate 34 and the front surface of the wedge member 30.

Therefore, when the piston 32 fitted in the cylinder 31 is driven backward, the pressing plate 34 integral with the output rod 33 compresses the spring 35, and the compression force moves the wedge member 30 to move the lifting rod 27. Push up,
The reference seat 28 is pressed against the lower end surface S ₂ of the multiple sleeve S.
When the multiple sleeves S are temporarily placed on the support bases 2 and 2, the lifting rod 27 whose weight presses the reference seat 28
Lowers while compressing the spring 26, and the lower end surface S ₂ of the multiple sleeve S can contact the support bases 2, 2. Side Clamp Means M4 As shown in FIGS. 1, 5 and 6, side clamp means M4.
4 is provided pair of the same structure, the side clamp means M4 of the left clamp the # 1 cylinder and # 2 both front and rear sides walls S ₄ of the cylinder, S _4, the right side clamping means M4 is Clamp both front and rear side walls S ₄ , S ₄ of the # 3 cylinder and the # 4 cylinder.

The left and right side clamp means M4 have a front-rear symmetrical structure with the multiple sleeve S interposed therebetween. Explaining the structure on one side of the front and rear, the side clamp means M4 is the base 1
A clamp arm 38 pivotally supported on a bracket 36, 36 erected on the base via a pivot 37 is provided, and the tip of an output rod of a cylinder 39 provided upward on the base 1 is linked to the link 4.
It is connected to one end of the clamp arm 38 via 0. Support member 41 fixed to the other end of the clamp arm 38
A pair of clamp members 43, 43 are pivotally supported on both ends of the clamp member via pivots 42, 42. Each clamp member 43 has a spring seat 44 provided below the clamp member 43 and a spring seat 45 provided below the support member 41. By tensioning the spring 46 between the upper and lower ends, the upper end is biased so as to incline toward the multiple sleeve S side. However, when the side clamping means M4 is in the unclamping position as shown in FIG.
3, 43, the back surface of the stopper surface 47 of the support member 41,
Since it abuts against 47, it is held parallel to the side wall S ₄ of the multiple sleeve S. Therefore, when the side clamp means M4 is set to the unclamp position and the multiple sleeve S is attached or detached,
It is possible to prevent interference between the multiple sleeves S and the clamp members 43, 43 and improve workability.

When the cylinder 39 is driven to extend, the tip of the clamp arm 38 swings downward, and the upper ends of the clamp members 43, 43 first come into contact with the side surface S ₄ of the multiple sleeve S. As a result, the clamp members 43, 43 are attached to the pivot 4
The springs 46 and 46 are swung while being stretched around 2 and 42, and the entire surface from the upper end to the lower end abuts against the side wall S ₄ of the multiple sleeve S and is clamped. The side walls S ₃ and S ₄ of the multiple sleeve are formed with unevenness to enhance the adhesion with the cylinder block made of aluminum alloy. The unevenness corresponding to the unevenness should be formed on the clamp members 43 and 43. Thus, the clamp members 43, 43 are prevented from slipping with the multiple sleeves S to achieve a reliable clamp.

Next, the operation of the embodiment of the present invention having the above-described configuration will be described.

First, the # 1 cylinder and # 4 cylinder of the unprocessed multiple sleeve S to be clamped are attached to the guide columns 3,
The lower end surface S ₂ of the multiple sleeve S is supported and temporarily placed on the two support bases 2 and 2 by being fitted to the outer circumference of the multiple sleeve 3. In this state, the cylinder 9 _U of the upper clamp means M1
To move the left and right clamp members 18 _UL and 18 _UR in a direction in which they approach each other, and the upper portions of the left and right side walls S ₃ and S ₃ of the multiple sleeve S are connected to the four rollers 22 _UL , 22 _UL and 22.
Clamp with _UR and 22 _UR . This allows multiple sleeves S
The upper part of the is centered and positioned in the left-right direction, and the tilt in the front-back direction is corrected.

Then, the cylinder 9 _L of the lower clamp means M2 is driven to move the left and right clamp members 18 _LL , 18 _LR in the direction of approaching each other, and the left and right side walls S ₃ , S _{3 of the} multiple sleeve S. The lower part of the four rollers 22 _LL , 22 _LL ,
Clamp at 22 _LR and 22 _LR . As a result, the lower portion of the multiple sleeve S is positioned, and movement and tilt of the multiple sleeve S due to the load during processing are prevented. When the cylinder 9 _L of the lower clamp means M2 is operated, the left and right clamp members 18 _LL and 18 _LR move in conjunction with each other as described above, and therefore the left rollers 22 _LL and 22 _LL and the right roller 2
2 _LR and 22 _LR have uniform pressure and the side wall S of the multiple sleeve S
₃ and S ₃ are abutted and the fall of the multiple sleeve S already clamped by the upper clamp means M1 is corrected.

In this way, when the multiple sleeves S are clamped and positioned by the upper clamp means M1 and the lower clamp means M2, the posture of the multiple sleeves S changes from the temporarily placed state, and the lower end surface S ₂ thereof is A pair of support bases 2, 2
May slightly rise from the.

Subsequently, the pistons 32 of the three sets of supporting means M3 are driven to push up the elevating rod 27, and the reference seat 2
8 is pressed against the lower end surface S ₂ of the multiple sleeve S. At this time, since the driving force of the piston 32 presses the wedge member 30 via the spring 35, the reference seat 28 is not pressed against the lower end surface S ₂ of the multiple sleeve S with an excessive load. Further, since the inclination angle of the wedge member 30 is set small, even if a downward clamping force is applied by the side clamping means M4, or a machining load is applied to the upper end surface S ₁ of the multiple sleeve S, The wedge member 30 will not be pushed back and the multiple sleeve S will not be displaced downward.

Subsequently, a pair of left and right side clamp means M4
Are operated to clamp the front and rear side surfaces of the # 1 cylinder to # 4 cylinder of the multiple sleeve S with a total of eight clamp members 43. As a result, the multiple sleeve S is pressed against the three reference seats 28, is positioned in the vertical direction, and is securely fixed so as not to fall in the front-rear direction having a small width. Then, the upper end surface S ₁ of the multiple sleeve S is cut by a processing device (not shown).

Next, prior to the use of the clamp device, the turnbuckle type first link 1 of the upper clamp means M1.
The structure of the centering master m for adjusting the lengths of 5 _UL and 15 _UR will be described.

As shown in FIGS. 9 and 10, the centering master
-M is a plate-shaped substrate 51, and pins 52,
A pair of support legs 53 and 53 fixed via 52, and a substrate
Short cylindrical shape fixed to the lower surface of 51 via pins 54, 54
And two dummy sleeves 55, 55. Two

As shown in FIGS. 11 and 12, prior to clamping the multiple sleeve S, four positioning pins 56 are provided.
... are the front columns 11 _L and 11 _R and the rear columns 12 _L and 12
Fit into the _R pin hole 57 ... From above. The four rollers 22 _UL , 22 _UL , 22 _UR of the upper clamp means M1 are attached to the two dummy sleeves 55, 55 of the centering master m.
Finely adjust the lengths of the left and right turnbuckle type first links 15 _UL and 15 _UR so that the 22 _URs come into contact with each other at the same time.

As described above, the first links 15 _UL , 15
By finely adjusting the length of _UR , 4 rollers 2
2 _UL , 22 _UL , 22 _UR and 22 _UR are adjusted to positions where the multiple sleeve S can be correctly positioned. Therefore, if the centering master m is removed and the multiple sleeve S is clamped,
The multiple sleeve S can be clamped in the correct position.

While the embodiments of the present invention have been described in detail above, various design changes can be made in the present invention without departing from the gist thereof.

For example, in the embodiment, a quadruple sleeve in which four unitary sleeves are integrally joined is illustrated, but the present invention is not limited to this.
It can also be applied to multiple sleeves such as three, three and five or more.

[0035]

As described above, according to the invention described in claim 1, the upper part of the side wall of each longitudinal end of the multiple sleeve is clamped by the upper clamp means, and the lower part of the side wall is clamped by the lower clamp means. Since the lower end surface of the multiple sleeve is supported by the supporting means, and both side walls along the longitudinal direction of the multiple sleeve are clamped by the side clamping means, the multiple sleeve without covering the upper end surface to be machined Can be accurately and reliably clamped, and a load for pushing the multiple sleeves downward and a load for tilting them forward and backward can be reliably opposed.

According to the second aspect of the present invention,
Since the pair of left and right clamp members can be moved symmetrically by the common cylinder, the multiple sleeves can be accurately positioned and the number of drive sources can be reduced.

According to the invention described in claim 3,
Since the pair of left and right clamp members can be moved symmetrically by the common cylinder, the multiple sleeves can be accurately positioned and the number of drive sources can be reduced. Also, when one clamp member comes into contact with the multiple sleeves first, the driving force of the cylinder is transmitted only to the other clamp member, and finally an even load is transmitted to both clamp members, which occurs during upper clamping. It is possible to correct the front-back tilt of the multiple sleeves.

According to the invention described in claim 4,
By bringing the reference seat into contact with the lower end surface of the multiple sleeve, it is possible to receive the load of machining applied to the upper end surface and prevent the multiple sleeve from being displaced downward. Moreover, since the load of the cylinder is indirectly transmitted to the wedge member via the spring, the wedge member is not driven by an excessive load.

According to the invention described in claim 5,
Since at least a pair of front and rear clamp members clamp both side walls along the longitudinal direction of the multiple sleeve, it is possible to reliably prevent the multiple sleeve from falling down in the front-rear direction. Moreover, since the postures of both clamp members are held parallel to the side walls of the multiple sleeves at the unclamp position, the multiple sleeves can be easily attached and detached without interfering with both clamp members.

According to the invention described in claim 6,
By mounting the centering master and adjusting the lengths of the pair of left and right first links, it is possible to easily initialize the positions of the pair of left and right clamp members of the upper clamp means.
