Abstract

(57) [Summary] [Purpose] To absorb positioning errors by simply sandwiching the tool cassette 3 between the plates 4 without tilting the tool 1 housed in the tool cassette 3. [Structure] A counterbore hole 3A smaller than the diameter of the collar 2 to be press-fitted into the tool 1 is drilled in the resin tool cassette 3, a slot 3B is attached around the counterbore hole 3A, and the tool is inserted into the counterbore hole 3A. The collar 2 is held under tension. Further, step portions 3C are provided at both ends of the tool cassette 3, the bottom surface 3D of the tool cassette 3 is formed in a convex shape, and a plurality of concave shapes are formed on the top surface 4A of the plate 4 to hold the bottom surface 3D of the tool cassette 3. , the stepped portion 3C of the tool cassette 3 is held by an inverted L-shaped holder 5.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

Printed circuit board processing machines use a large number of tools for drilling and other operations. others Therefore, the processing machine is equipped with a tool storage mechanism to store a large number of tools. This idea is This is about a tool storage mechanism that holds a large number of tools.

0002

[Conventional technology]

Next, the configuration of a conventional tool storage mechanism will be explained with reference to FIG. 1 in Figure 3 is 2 is a collar, 6 is a tool cassette, and 6A is a counterbore. Tool 1 is empty -2 is press-fitted, and the tool 1 is stored in the counterbore hole 6A using the collar 2 as a guide. Figure 3 By arranging multiple tool cassettes 6, a large number of tools can be stored. Wear. The structure of the tool cassette 6 is also described in Japanese Patent Publication No. 2-29456. has been done.

0003

[Problem that the idea aims to solve]

The tool cassette 6 in Fig. 3 is made of metal, and the counterbore hole 6A is slightly larger than the collar 2. I can open it. The tool 1 stored in the tool cassette 6 is exposed to vibrations of the processing machine, etc. The tool 1 may not be replaced smoothly. This idea uses a resin tool cassette, and the diameter of the counterbore hole is smaller than Collar 2. Collar 2 is tensioned by creating a slot around the counterbore hole. Hold the tool 1 in the tool cassette without tilting it. Provides a tool storage mechanism that absorbs positioning errors by simply inserting the tool into the plate. With the goal.

0004

[Means to solve the problem]

In order to achieve this purpose, in this invention, the diameter of the collar 2 to be press-fitted into the tool 1 is A small counterbore hole 3A is drilled in the resin tool cassette 3, and the circumference of the counterbore hole 3A is A slot 3B is attached to the surrounding area, and tension is applied to the collar 2 inserted into the counterbore hole 3A. hold in condition. In addition, step portions 3C are provided at both ends of the tool cassette 3, and the tool cassette The bottom surface 3D of the plate 4 is formed into a convex shape, and the top surface 4A of the plate 4 is formed with a plurality of concave shapes. The bottom surface 3D of the tool cassette 3 is held, and the stepped portion 3 of the tool cassette 3 is held with the inverted L-shaped holder 5. Hold C.

[0005]

[Effect]

Next, the structure of the tool storage mechanism according to this invention will be explained with reference to FIG. 3 in Figure 1 is A tool cassette made of resin, 4 is a plate, and 5 is a holder. In tool cassette 3 , a counterbore hole 3A smaller than the diameter of the collar 2 to be press-fitted into the tool 1 is drilled, and the counterbore hole 3A is A slot 3B is attached around the hole 3A. This allows tool 1 with collar 2 to be When inserted into the countersunk hole 3A, the elasticity of the slot 3B puts the collar 2 under tension. Keep it in the state. Therefore, even if the tool 1 is tilted and inserted into the counterbore hole 3A, the tool 1 becomes erect.

[0006] A stepped portion 3C is provided at both ends of the tool cassette 3, and the bottom surface 3D of the tool cassette 3 is Formed in a convex shape. A plurality of concave shapes are formed on the upper surface 4A of the plate 4, and the upper surface 4A The bottom surface 3D of the tool cassette 3 is held in the recess. The inverted L-shaped holder 5 is a tool cage. Hold the stepped portion 3C of the kit 3 from both sides. Tool cassette 3 is sandwiched between plate 4 There is a play of about 0.05 mm in the horizontal direction, and 1. Since there is a play of about 5 degrees, positioning errors can be absorbed.

[0007] Next, the assembly diagram of FIG. 1 is shown in FIG. 2. In Figure 2, a tool that can accommodate 10 tools 1 is shown. Five cassettes 3 are incorporated and accommodate 50 tools 1.

[0008]

[Effect of the idea]

According to this invention, a resin tool cassette is used, and the diameter of the counterbore hole can be colored. The collar is made smaller and has slots around the counterbore, making it easier to tighten the collar. The tools stored in the tool cassette will not tilt. . In addition, since the tool cassette is simply inserted between the plates, it can be used horizontally and with respect to the tool. There is some play, and positioning errors can be absorbed.
