Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a tool holder for organizing and storing tools such as a chucking tool or a taper shank for holding the chucking tool in a cabinet, wagon, etc. It is something.

(Prior art) As a conventional tool holder of this type, it was developed in 1983.
"Holder for tool storage" described in Publication No. 78088
There is a fitting groove on the inner surface,
It has a flange edge on the front and back of the outside, and one flange edge is extended inward by an appropriate length and has a lug tooth carved into it, and the other brim edge is engraved with a lug tooth that meshes with the above-mentioned lug tooth. The pair of retaining members provided are assembled so that the rack teeth mesh with each other and the fitting grooves face each other, and by changing the meshing of the rack teeth, the distance between the fitting grooves can be changed, and the tool The handle of the fitting groove is held between the side walls of the fitting groove.

In other words, this holder was a two-point support in which the handle of the tool was held between the side walls of the pair of fitting grooves, so in order to support the handle of the tool without wobbling, the side walls of the fitting groove had to be supported. must have a curved surface equal to the curvature of the outer circumferential surface of the handle of the tool with the largest diameter. Therefore, unless the diameter of the handle of the tool to be held exceeds the maximum distance between the side walls of the fitting grooves when the holding members are in close contact with each other, there is a risk that the tool may wobble and fall sideways during transportation.

(Purpose of the invention) In order to eliminate and solve the problems of the above-mentioned conventional technology, the present invention supports tools at three or more points so that tools from the largest diameter to the smallest diameter may fall down during transportation. The object of the present invention is to provide a tool holder that can be held without any problems.

(Structure of the invention) The tool receiver according to the invention has at least three parts of the circumferential wall of the cylindrical body 2 having an inner diameter into which the largest diameter tool A can be fitted, and has parallel side walls _3. , 3 ₁ are formed, and in each bulge 3, side walls 3 ₁ , 3 ₁ are formed.
A receiver main body 1 having a plurality of longitudinal teeth 3 ₂ ... 3 ₂ , 3 ₂ ... 3 ₂ formed at equal intervals on the inner surface thereof, and the bulging portion 3
Groove 4 that meshes with tooth 3 ₂ … 3 ₂ , 3 ₂ … 3 ₂ of … 3 ₁ … 4
₁ , ₄₁ ... ₄₁ are formed on both sides of the support bodies 4...4.

Note that the inner diameter of the cylindrical body 2 decreases downward in accordance with the tapered shape of a tool such as a taper shank, thereby preventing the seal from falling off. Further, _{the upper} ends of the teeth _{3 2 .} 4 ₁ is formed with the upper end remaining.

Therefore, the support body 4 is connected to the grooves 4 ₁ ...4 ₁ , 4 on both sides thereof.
₁ ...4 ₁ to the side wall of the bulge 3 ₁ ...3 ₁ teeth 3 ₂ ...3 ₂ , 3 ₂ ...
_3. When inserted from above so as to be engaged with the support member 4, the portion without the groove at the upper end of the support member 4 rests on the stepped portion, thereby preventing the support member from falling off. Further, in this embodiment, there are three bulges, and one end surface of the support body 4 is a curved surface matching the curvature of the circumferential surface of the tool having the largest diameter, but it may be a flat surface.

(Function of the invention) Next, in accordance with the above structure of the invention, the specific usage and operation of the tool receiver according to the invention will be explained with reference to the illustrated embodiment.

That is, in each bulging part 3 of the tool receiver of the present invention, the grooves 4 ₁ ... 4 ₁ , 4 ₁ ... 4 ₁ of the support body 4 are connected to the teeth 3 ₂ ... 3.
₂ , 3 ₂ ... When inserted from above so as to mesh with 3 ₂ , by changing the insertion point, the distance from the center of the cylindrical body 2 to the end face of the support body 4 can be adjusted by one bit of the tooth 3 ₂ . Because you can change
If the shaft diameter of the tool is small as shown in Figure 3a, insert the supports 4...4 according to this shaft diameter, and
For the maximum diameter, as shown in FIG.
...It is supported by the end face of 4. In order to change the once set diameter, it is sufficient to push up the supports 4 from below, remove them, and insert them again to match the diameter.

(Effects of the invention) As described above, according to the tool receiver according to the invention, at least three parts of the peripheral wall of the cylindrical body having an inner diameter into which the largest diameter tool can be fitted are made to protrude outward. A bulge is formed, and a support whose end face position can be changed bit by bit by teeth and grooves is inserted into this bulge, and a tool is driven by the end faces of three or more supports. Because it is designed to hold, unlike conventional two-point holders,
It can securely hold even extremely small diameter tools, the receiver body and support are separate, and its structure is simple, so it has great practical effects such as being suitable for mass production. .
