Description

Description: TECHNICAL FIELD The present invention relates to a device for tightening and fixing a handling tooth when assembling a handling cylinder of a thresher, and more particularly, a device and a device provided with a plurality of such fastening and fixing devices. It relates to a coupling means of the device.

(Prior Art) A large number of handle teeth are attached to the handle of a threshing machine, and in order to firmly fix the handle to the handle with a constant tightening pressure, a dedicated tightening and fixing device has been conventionally used. It is used. In this device, a long insert is inserted into the body of a handling barrel placed at a predetermined position, a nut tightening tool attached to the tip of the insert is appropriately opposed to the nut, and the tool is rotated to rotate the nut. The handle teeth are fixed to the handle cylinder by tightening. The applicant has applied for a handle tooth clamping and fixing device for a handle cylinder, which is a further improvement of this conventional technique, as Japanese Patent Application No. 56-105824 (Japanese Patent Laid-Open No. 58-10435). This device is capable of rotatably supporting a large-diameter handling cylinder and a small-diameter handling cylinder at the same time between a fixed support and a movable support of the device. It is equipped with an insert that can be used for both of the handling cylinders, and this insert can be moved on the bed of the device in any of the front, back, left and right directions and can be inserted into the body of the handling cylinder of any size. , The handle teeth are fixed to the handle cylinder by a nut tightening tool attached to the tip of the insert.

(Problems to be Solved by the Invention) Although the conventional device described above can be used for tightening and fixing although the diameter of the handling cylinder is relatively large, a tool for tightening the tip of the handling cylinder having a small diameter can be used. It is not possible to insert the insert with the insert into the barrel of the handling cylinder, or even if it can be inserted, create the gap required to tighten the nut (the gap between the insert and the inside diameter of the handling barrel). May not be possible. Therefore, the conventional device cannot be used for the handling cylinder having such a small diameter.

Furthermore, even for a type of handle that has its handle teeth clamped and fixed from the outside of the handle even if the handle has a large diameter, insert the conventional tightening tool into the handle and fix it securely. There is a problem that the type of device that cannot be used cannot be used.

Therefore, it is an object of the present invention to fix the handle teeth by one handle tightening and fixing device regardless of the size of the handle cylinder. Moreover, the handle tooth tightening and fixing device has a structure. It is easy and compact.

(Means for Solving Problems) The present invention is, as means for solving the above problems, a fixed support frame 9 and movable support frames 12 and 13 for rotatably supporting a plurality of handling bodies 1 and 2 in parallel. Are provided on the base 8 and the base 8

A carriage 28 is mounted on the bed 7 so as to be reciprocally movable, and the carriage 28 is mounted on the carriage 28.
In the device in which the insert 31 having the first tightening tool 46 for tightening and fixing the handle teeth 3 at the tip is horizontally attached, the moving base 38 and the carriage 28 are connected via the pneumatic cylinder device 33. The first and second tightening tools 46 and 37 are interlocked and coupled with each other with a play of a distance between the moving start ends thereof, and the second drive motor 47
However, the handle 28 is reciprocally moved, and the movable base 38 is reciprocally moved via the pneumatic cylinder device 33.

(Operation) When tightening and fixing the handle teeth to the handle cylinder, temporarily fix the handle teeth to the handle cylinder beforehand, and rotate the temporarily fixed handle cylinder to the fixed support frame 9 and the movable support frames 12 and 13. While supporting, the second drive motor 47 is operated to move the carriage 28 in the direction of the handling cylinders 1 and 2, and is directed downward from the first tightening tool 46 or the movable table 38 fixed to the tip of the insert body 31. The second tightening tool 37, which is fixed in place, is positioned at a position where the handle teeth 3 of the handle cylinder 1 or handle 2 are tightened, and the tightening tools 46 and 37 are rotated to tighten the handle nuts 3. , Or the bolts are securely tightened and fixed at a constant pressure, but at this time, the carriage 28 and the moving base 38 are provided with a play of the distance between the moving start ends of the first and second tightening tools 46 and 37 via the cylinder device 30. Since the dolly 28 is motion-coupled, even if the carriage 28 starts to move in the directions of the handling cylinders 1 and 2, only the cylinder 34 moves and the inside of the cylinder 34 moves. Piston 35 does not move that location. When the cylinder 34 moves in the above play distance in the direction of the handling cylinder and the left end of the cylinder 34 contacts the piston 35, the left end of the cylinder 34 moves the piston 35 in the handling cylinder 1 and 2 directions to move the piston rod 36. The moving table 38 is moved via the. When the left end of the cylinder 34 contacts the piston 35, the first tightening tool 46 fixed to the tip of the insert body 31.

When the tightening is completed, the second tightening tool 37 is released from the fixing tool 4 ', and then the first drive motor 26 is driven to rotate the fixed side fitting body 20 by a predetermined angle via the gear mechanism (not shown). Then, the integrated small-diameter handling cylinder 1 is rotated so that the second tightening tool 37 faces the fixing tool 4'for the next tightening, and tightening is performed in the same manner. When the second tightening tool 37 is further moved in the arrow B direction, the second drive motor 47 is driven. In this way, the handle 1 is rotated and the movable table 40 is sequentially moved to fix the handle 3 to the handle 1 with a constant tightening pressure.

Of course, if the handle teeth 3 are clamped and fixed from the outside, the handle teeth can be clamped and fixed to the large diameter handle cylinder by the second tightening tool 37.

Next, when the handle teeth 3 are fastened and fixed to the large-diameter handle cylinder 2, the large-diameter handle cylinder 2 is fixed in the same manner as the small-diameter handle cylinder 1 with the fixed support frame 9 and the movable support frame.
After being rotatably supported by 13, the second drive motor 47 is driven to move the carriage 28 in the direction of the arrow B, and the tip of the insert body 45 is passed through the fixed side fitting body 21 to enter the large diameter handling cylinder 2. Insert and first
The tightening tool 46 is opposed to the nut 4 of the handle tooth 3, the first tightening tool 46 is rotated, and the nut 4 is tightened and fixed at a constant tightening pressure. The subsequent operation is exactly the same as in the case of the small diameter handling cylinder 1.

When the tightening work is completed, the carriage 28 is returned to the position shown in FIG. 1, and both the first tightening tool 46 and the second tightening tool 37 are returned to the movement start end position. Move the movable support frames 12 and 13 from there to the arrow B.
The handling barrel 1 or the handling barrel 2 may be removed by moving the handling barrel 1 in the direction.

(Effect of the invention) According to the present invention, when the handle teeth are clamped and fixed to the handle cylinder, the carriage has the first tightening tool for fixing the handle teeth from the inside of the handle cylinder and the handle teeth are tightened from the outside. The movable table having the second tightening tool, which is to be fixed, is interlockingly connected through the pneumatic cylinder device to create play in which the movable table does not move with respect to a certain moving distance of the carriage, and the same drive source is used to Since the trolley can be moved, one type of tightening and fixing work is required for both the type in which the handle teeth are fixed to the handle body from the outside and the type in which the handle teeth are fixed to the handle body from the inside. Since it can be done by a device, the handle teeth can be clamped and fixed regardless of the size of the handle cylinder, which is extremely convenient. In addition, since the second bed can be shortened by the amount of play by creating play on the movable table as described above, the overall length of the handle clamping device can be shortened and made compact.
