When cutting the tool mounting groove that requires a high degree of accuracy by forming a single tool bar and making a plurality of rotations in the combined state as described above to prevent the problem that the groove can not be cut. Work time is reduced by disassembling and combining many times by the operator while minimizing the error. A tool for the machine tool to be able to solve the problems that would delay the manufacture of the angle switching device.

In general, the tool post is coupled to a machine tool, a plurality of tool mounting grooves 2 are formed as shown in Figure 1 so that a plurality of tools (1) for processing the workpiece can be mounted.

In addition, when machining the workpiece with each tool (1) mounted in the tool mounting groove (2), each tool 1 is used alternately according to the intended use, wherein the tool (1) is a workpiece When the tool is rotated to the position for machining, the machining precision is ensured only when the first tool 1 is always the same as the cutting angle when cutting the workpiece.

Therefore, when machining the contact surface (3) of the tool mounting groove (2) should be a high precision cutting to be perpendicular to the outer surface of the tool rest (10).

As described above, the prior art for processing the outer surface of the tool mounting groove 2 and the tool post 10 will be described below.

The outer surface and the tool mounting groove 2 of the tool stage are formed. By the multiple times of separation and coupling by the operator, the problem that the angles show a slight difference from each other unlike the intention of the operator occurs.

That is, the outer surface and the tool mounting groove should be cut at right angles to each other. When the tool post is rotated by a predetermined angle in a state where the tool post is fixed with a coupling hole, another tool mounting groove 2 is placed at the position of the first tool mounting groove 2. It should be located exactly as shown in Figure 1, because the plurality of tool mounting grooves (2) are used by mounting tools (1) for different purposes, the tool stage 10 is rotated a number of times during operation If the tool stage 10 is rotated and the tool 1 is in contact with the workpiece and an error occurs in the cutting angle with the workpiece, the work is not performed according to the intention of the worker. This is because a problem that requires precision is a big problem.

Therefore, when the workpiece is processed after the tool is mounted on the tool post, the cutting angle of each tool is inevitably slightly different when each tool cuts the workpiece, thereby causing a large error in the workpiece. .

The present invention has been made in order to solve the problems as described above is to make a plurality of angle conversion by a single combination when manufacturing the tool stand to be able to process the tool mounting groove and the outer surface of the tool stand at one time mounting to each tool mounting groove It aims to reduce the error of the cutting angle between the tools and the workpiece to be minimized.

First, insert the insertion hole of the unprocessed workpiece into the insertion portion 107 of the shaft 105 and then match the screw hole 114 formed in the interlocking gear 113 with the second coupling hole 106 of the workpiece. It can be fastened to the fixing bolt 116.

Then, the fixing bolts 116 are fastened to the plurality of second coupling holes 106 and the screw holes 114 by the above-described procedures, so that the workpieces can be firmly coupled to one side of the interlocking gear 113. .

In addition, in order to prevent the workpiece coupled to the interlocking gear 113 from shaking or shaking during cutting, the ridge 102 is formed by the third crown gear 119 coupled to the other side of the support jaw 104 of the shaft 105. The first crown gear 117 of the fixed body 117 and the second crown gear 118 of the interlocking gear 113 coupled to the outer side of the fixed body 117 can be pressed and fixed, which is supplied from an external hydraulic discharge device. The hydraulic pressure is supplied to the second hydraulic chamber 125 through a second flow path (not shown), so that the piston 123 is moved to the first hydraulic chamber 124 side by hydraulic pressure to accompany the shaft 105 to the right. Will be transferred.

At this time, since the support jaw 104 and the third crown gear 119 of one end of the shaft 105 are also transferred to the right side (in the drawing), the first and second crown gears 118 are connected to the third crown gear 119. By being firmly pressed by the, at the same time, the teeth of the first, second, third crown gear 119 is precisely meshed with each other as shown in Figure 3a is to be corrected so as not to shake the workpiece during cutting.

As described above, when the workpiece is coupled to the subject innovation, the subject innovation is disposed to be machined into a machining center, and then the first and second outer surfaces (a) and (b) of the tool post 110 are shown in FIG. 4. One side and the other side of the workpiece are cut so as to be perpendicular to form a cutting edge, and the cutting operation of the first and second outer side surfaces (a) and (b) is completed soon after the first and second outer side surfaces (a) ( From b), the first and second tool mounting grooves A and B are cut into horizontal grooves as shown in FIG.

At this time, the first and second tool mounting groove and the first and second outer surface (a) (b) should be cut to be perpendicular to each other, the first and second tool mounting groove (A) ( In order to allow B) and the first and second outer surfaces a and b to be perpendicular to each other, if the tool post 110 is slightly shaken or shaken during the cutting operation, cutting at the correct angle becomes difficult. Since the third crown gear 119 can press the first and second crown gears 118 to prevent shaking of the tool post 110 to be processed together, it is possible to achieve cutting operations with high precision. .

Therefore, when the hydraulic pressure generated from the hydraulic generator is supplied to the first hydraulic chamber 124 through the first flow path (not shown) according to the intention of the operator, the first hydraulic chamber 124 is expanded, and at this time, the piston ( 123 is moved to the left side (in the drawing) as the first hydraulic chamber 124 is expanded, and simultaneously moves the shaft 105 to the third crown gear 119 as shown in Figure 3b the first and second crown gears. Detaching from 118 allows the interlocking gear 113 to be rotatable.

When the driving motor 108 is rotated at a predetermined angle by a preset value, the driving gear 111 rotates the interlocking gear 113 by a predetermined angle, and is processed according to the rotation of the interlocking gear 113. When the tool post is rotated by a predetermined angle, the part to be machined to the third and fourth outer surfaces c and d is rotated to the position of the first and second outer surfaces a and b.

In addition, after the workpiece is rotated to the cutting position as described above, the hydraulic pressure is supplied to the second hydraulic chamber 125 through the second passage (not shown) to transfer the piston 123 and the shaft 105 to the right. The third crown gear 119 of the support jaw 104 allows the first and second crown gears 118 to be pressed and fixed.

Therefore, the machining center (not shown) may cut the third and fourth outer side surfaces (c) and the third and fourth tool grooves by cutting the workpiece rotated to the cutting position.

By cutting the fifth, sixth, ..., n-th outer surface and fifth, sixth, ... n-th tool mounting grooves by the above-described procedure, the worker separates and joins the workpiece. By doing this, the cutting error generated can be minimized.

As described above, the present invention solves the inconvenience of repeatedly performing separation and joining of the workpiece by making a plurality of angular rotations with a single combination when manufacturing the tool stand, and thus, the outer surface of the tool stand and the tool mounting groove have a precise right angle. In order to maintain the state, it is a very useful invention to reduce the cutting angle error of the tools and the workpiece mounted in the tool mounting groove to the minimum.
