Tool holder for direct inspection and positioning of tools

The invention relates to a tool holder, in particular to a tool holder for directly inspecting and positioning a tool.

The conventional tool holds the tool through a tool holder before grinding, and further positions the tool through a positioning device, wherein the tool holder includes a front nut and a rear screw which are mutually screwed. a cap, the collet and the rear nut are provided with a collet, and the collet is provided with a clamping hole, and the outer edge of the front nut is flattened with a positioning surface, thereby the tool is provided Inserted in the clamping hole, and then placed the collet between the front nut and the rear nut, and then the positioning device is in a state where the front nut and the rear nut are not locked Auxiliary, rotating the tool so that the cutting edge of the tool is parallel to the positioning surface to complete the positioning of the tool, and finally the front nut and the rear nut are screwed to each other to complete the tool before grinding operation.

However, due to the above-mentioned tool positioning mode, positioning by the positioning device is required, rather than direct positioning. Therefore, after the positioning is completed, it is usually required to further manually check whether the tool edge positioning is correct, which is not only very troublesome, and It must rely on the experience of the operator. Generally, beginners need to spend more time to adjust the positioning. Especially when the tool is a small tool, the blade of the small tool is too small to increase the difficulty of visual judgment, making the positioning of the tool difficult. The disadvantage of high and low precision is that, after observing the above disadvantages, the inventor of the present invention believes that there is still a need for further improvement of the conventional tool positioning method, and the present invention is produced.

The 46-type elastically abuts against the positioning surface 22 of the adjusting ring 20, wherein the elastic abutting member 46 includes a sleeve 461, and the two ends of the sleeve 461 are an open end 462 and a closed end 463, respectively. A spring 464 and a positioning bead 465 are disposed in the sleeve 461, and the positioning bead 465 is abutted against the positioning surface 22 of the adjusting ring 20 by the elastic force of the spring 464.

For a further understanding of the structural features of the present invention, the application of the technical means, and the intended effect, the manner of use of the present invention will be described. It is believed that the present invention may be more deeply and specifically understood as follows:

Please refer to FIG. 2 and FIG. 4 first. When the user wants to position the cutting edge 201 of a cutter 200, firstly, the cutter 200 is first placed into the clamping hole 121 of the collet 12, and then the cylinder is placed. The clip 12 is placed in the tapered hole 111 of the front nut 11 and is screwed into the first threaded portion 112 of the front nut 11 through the second threaded portion 131 of the rear nut 13 to make the rear nut 13 Pushing the collet 12 toward the front nut 11 , thereby causing the tapered hole 111 of the front nut 11 to have a wedge shape to press the collet 12 to contract inwardly, and can surely achieve the clamping The effect of the tool 200.

Referring to FIG. 5 and FIG. 6 again, after the user completes the clamping operation of the tool 200, the positioning of the blade 201 of the tool 200 can be started. First, the viewing and positioning unit 40 is mounted on the tool. Adjusting the ring 20, then relaxing the pressing member 30, and rotating the adjusting ring 20 to rotate the viewing positioning unit 40 relative to the tool holder 10, so that the positioning line 431 is aligned with the cutting edge 201 of the tool 200, so that the tool can be made The blade 201 of the 200 is indirectly aligned with the positioning surface 22, and finally the locking member 30 is locked to fix the position of the adjusting ring 20, that is, the positioning of the tool 200 is completed, thereby eliminating the need for the user to use other positioning devices. The positioning of the tool 200 can be completed simply, quickly and directly, and the speed, accuracy and convenience of the tool positioning can be improved.

It is worth mentioning that, since the clamping arm 42 of the clamping seat 41 is provided with the elastic abutting member 46, when the clamping arm 42 is clamped to the adjusting ring 20, the positioning bead 465 is subjected to the spring 464. The elastic force abuts against the positioning surface 22 of the adjusting ring 20, so that the clamping arms 42 are more firmly clamped to the adjusting ring 20.

It is worth mentioning that through the openings 45 and the through holes 421, the external light is illuminated by the four sides of the inspection hole 43 to illuminate the tool 200, and no other lighting tools are needed, that is, the user can clearly Examine whether the tool 200 is actually positioned.

Referring to FIGS. 7 to 9, the scale 116 provided on the outer peripheral side of the front nut 11 and the reference line 231 disposed on the outer peripheral side of the adjusting ring 20 allow the user to finely adjust the cutter 200. The cutting edge 201 is such that the cutting edge 201 is inclined to the positioning line 431 in the following manner. First, the pressing member 30 is loosened, and the reference line 231 of the adjusting ring 20 is engaged with the scale 116 of the front nut 11 Fine-tune the adjusting ring 20, and then tighten the pressing member 30 after fine adjustment, thereby further satisfying the grinding requirements of different types of tools, such as adjusting the sharp corner protection of the milling cutter or adjusting the cutting edge profit of the drill.

It is worth mentioning that the first inclined surface 115 of the front nut 11 and the second inclined surface 23 of the adjusting ring 20 prevent the scale 116 and the reference line 231 from being worn out for the user to watch and fine tune.

Please refer to FIG. 10 again, which is a schematic diagram of adjusting the grinding length of the tool according to the present invention, and please refer to FIG. 2 to consider that some tools need to be positioned during grinding to protrude the tapered hole 111. The length H, so that the user can still position the length H of the tool 200 by using a conventional positioning device 300, and then the positioning of the blade 201 is performed together with the viewing and positioning unit 40. The positioning device includes a base 301. The base 301 is provided with a fixing hole 302, and a fixing block 303 is disposed adjacent to the fixing hole 302. The base 301 is further provided with an adjusting block 304, so that the user only needs to clamp the tool 200. The clamp body 10 is disposed in the fixing hole 302, and the positioning surface 22 is blocked by the fixing block 303, so that the front nut 11 cannot be rotated, and the user only needs to loosen the front nut 11 and the rear screw slightly. The cap 12 can adjust the length H of the cutter 200 so that the blade 201 of the cutter 200 abuts against the adjusting block 304, and then the front nut 11 and the rear nut 12 are interlocked with each other, and the cutter can be positioned. The length of 200 is H.

Hereafter, the features of the present invention and its achievable efficacy are stated as follows:

The tool holder 100 for directly viewing and positioning the tool provided by the present invention, the user only needs to first clamp a tool 200 to the clamp body 10, and then the inspection positioning unit 40 is clamped to the adjustment ring 20, and then rotate the The adjusting ring 20 drives the viewing positioning unit 40 to rotate relative to the tool holder 10, and the positioning line 431 is aligned with the cutting edge 201 of the tool 200, so that the cutting edge 201 of the tool 200 is indirectly aligned with the positioning surface 22 to complete the The positioning of the tool 200 allows the user to perform the positioning of the tool simply, quickly and directly, thereby improving the speed, accuracy and convenience of the tool positioning.
