[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Referring to 1-4, the utility model provides a fine-adjustable CNC lathe tool holder, comprising a tool body 1, a fixing mechanism 4 is arranged on the outer side of the tool body 1, and a fine-adjustment docking mechanism 5 is arranged at the bottom of the fixing mechanism 4;

[0026] The fixing mechanism 4 includes a knife seat body 41 and an adjusting groove 46. The adjusting groove 46 is arranged inside the knife seat body 41. A protruding block 45 is arranged at the bottom of the knife seat body 41. A tension adjustment rod 42 is arranged inside the adjusting groove 46. The tension adjustment rod 42 passes through the rear surface of the knife seat body 41. An auxiliary turntable 44 is arranged at one end of the tension adjustment rod 42. A push block 43 is arranged at the other end of the tension adjustment rod 42. A guide block 47 is arranged on the other side of the push block 43. A clamping block 48 is arranged on the other side of the guide block 47. Guide grooves 413 are arranged on the opposite surfaces of the clamping block 48 and the knife seat body 41. Limiting protrusions 414 are symmetrically arranged on both sides of the guide groove 413. Slide blocks 49 are symmetrically arranged on both sides of the clamping block 48. A sliding groove 410 is arranged on the outer side of the sliding block 49. A vertical rod 411 is arranged inside the sliding block 49, and a spring 412 is arranged on the outer side of the vertical rod 411.

[0027] When in use, by rotating the auxiliary turntable 44 in the opposite direction, it drives the tension adjustment rod 42 to fit the thread of the knife seat body 1 and pull the push block 43 at the other end to move in the same direction, and no longer generates thrust on the guide block 47, so that the spring 412 loses the external force to resist the rebound and pushes the sliding block 49 to move along the slide groove 410 on the outside of the vertical rod 411, allowing the clamping block 48 to move close to the knife body 1 to complete the clamping and fixing. Because the device can be operated with one hand, the installation convenience of the device is further increased.

[0028] The fine-tuning docking mechanism 5 includes a mounting plate 51 and a fixing through hole 52. The fixing through holes 52 are arranged at the four corners of the mounting plate 51. A groove 53 is arranged on the top surface of the mounting plate 51. A fine-tuning rod 55 is arranged inside the mounting plate 51. An adjusting disk 54 is arranged on one side of the fine-tuning rod 55. The other side of the fine-tuning rod 55 is connected to the tool holder body 41. By rotating the adjusting disk 54 to make it fit the thread of the mounting plate 51, the tool holder body 1 is pushed to move along the groove 53 through the protruding block 45 to fine-tune the center horizontal height of the turning tool.

[0029] A blade head 2 is arranged on one side of the blade body 1, and fitting protrusions 3 are arranged on both sides of the blade body 1. Fitting grooves are arranged on both sides of the fitting protrusion 3; the stability of the connection is enhanced by the fitting protrusion 3 and the fitting groove.

[0030] The adjustment groove 46 runs through the top surface and the front side surface of the tool holder body 41, and the two ends of the spring 412 are fixedly connected to the inner wall of the slide groove 410 and the slider 49 respectively. The slide groove 410 is symmetrically arranged on both sides of the adjustment groove 46. The shapes of the guide block 47 and the push block 43 are both right-angled trapezoids. The tension adjustment rod 42 is connected to the push block 43 through an idle bearing seat, and the connection between the tension adjustment rod 42 and the tool holder body 41 is provided with matching threads; the tension adjustment of the clamping block 48 is achieved by pushing the push block 43 through the guide block 47.

[0031] The shape of the fitting protrusion 3 matches the shape of the guide groove 413, and the shape of the fitting groove matches the shape of the limiting protrusion 414. Through the docking of the fitting protrusion 3 and the guide groove 413, the device fixes the blade 1 more stably.

[0032] The fine-tuning rod 55 is connected to the knife seat body 41 through an idle bearing seat. The shape of the groove 53 matches the shape of the protruding block 45. The connection between the fine-tuning rod 55 and the mounting plate 51 is provided with matching threads. The fine-tuning of the device is achieved by the fine-tuning rod 55 matching the threads of the mounting plate 51.

[0033] Working principle: When in use, the auxiliary turntable 44 is rotated so that the auxiliary turntable 44 drives the tension adjustment rod 42 to fit the thread of the knife seat body 1 and pushes the push block 43 at the other end to move in the same direction, so that the push block 43 fits the guide block 47, so that the clamping block 48 moves along the slide groove 410 on the outside of the vertical rod 411 through the slider 49, and at the same time compresses the spring 412, and then aligns the fitting protrusion 3 of the target blade 1 with the guide groove 413, and at the same time, the fitting groove and the limiting protrusion 414 are docked for auxiliary installation, and the adjusting groove 46 and the clamping block 48 are placed on the opposite sides of each other, and then the auxiliary turntable 44 is rotated in the opposite direction to drive the tension adjustment rod 42 to fit the knife seat The thread of the main body 1 pulls the push block 43 at the other end to move in the same direction, and no longer generates thrust on the guide block 47, so that the spring 412 loses the external force to resist the rebound and pushes the sliding block 49 to move along the slide groove 410 on the outside of the vertical rod 411, allowing the clamping block 48 to approach the blade 1 to complete the clamping and fixing. Because the device can be operated with one hand, the installation convenience of the device is further increased; when it is necessary to make the horizontal height of the center of the turning tool consistent with the horizontal height of the rotation axis of the part, rotate the adjusting disk 54 to make it fit the thread of the mounting plate 51 to push the tool holder main body 1 to move along the groove 53 through the protruding block 45 to fine-tune the center horizontal height of the turning tool.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
