[0002] The machining of small-diameter deep holes is a technical problem in machining. Restricted by problems such as the structural characteristics of the drill bit, chip breaking, chip evacuation, and cutting speed, there are problems such as low machining accuracy, poor surface quality of the hole wall, and low machining efficiency when drilling small-diameter deep holes by conventional methods. At present, the machining of small-diameter deep holes generally adopts methods such as stepped feed drilling, low-frequency or ultrasonic vibration drilling, and other special machining methods. However, these methods have problems such as low efficiency or high usage cost. Therefore, a self-excited vibration drilling tool shank is required, and the self-excited vibration drilling tool shank is a special tool, and its design allows self-excited vibration to be generated during the drilling process. This vibration can be controlled and adjusted through a specific mechanical structure or system to improve the drilling efficiency, reduce the cutting force, extend the tool life, or improve the quality of the machined surface. The methods to achieve self-excited vibration may include using piezoelectric ceramics, electromagnetic drivers, or mechanical resonance systems, etc. The tool replacement structure of the drilling tool shank is bloated and cumbersome, unable to ensure the rapid replacement of the tool, and at the same time lacking a certain adjustment ability, resulting in certain limitations in the use process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4The utility model provides a technical solution: a self-excited vibration drilling tool handle device, comprising: an ultrasonic tool handle 1, and a mounting base 2 fixedly mounted on one end of the ultrasonic tool handle 1; a tool head body 4 is arranged inside the mounting base 2 through a mounting mechanism 3; and an adjustment component 5 is arranged at the bottom of the ultrasonic tool handle 1.

[0025] The mounting mechanism 3 includes a circular groove 41 provided inside the mounting seat 2 for inserting the cutter head body 4, and a clamping groove 42 is provided on both sides of the cutter head body 4. Both sides of the circular groove 41 are connected to a groove body 43, and a clamping block 44 is slidably installed inside the two groove bodies 43. The adjacent sides of the two clamping blocks 44 are clamped with the clamping groove 42 on the surface of the cutter head body 4, and the surface of the mounting seat 2 is provided with an abutment 40 for limiting the clamping block 44.

[0026] The abutment member 40 comprises a movable sleeve 401, a fixed ring 402, a support spring 403 and a storage groove 404. The surface of the mounting seat 2 is movably sleeved with the movable sleeve 401. Both sides of the inner wall of the movable sleeve 401 are provided with storage grooves 404 for receiving the clamping block 44. A fixed ring 402 is fixedly installed on one side of the movable sleeve 401. Two support springs 403 are clamped on one side of the fixed ring 402. One end of the two support springs 403 are clamped on the surface of the mounting seat 2. The cutter head body 4 is movably sleeved at the axis of the fixed ring 402.

[0027] In this embodiment, the ultrasonic knife handle 1, also known as an ultrasonic knife handle, is a tool that adds longitudinal high-frequency ultrasonic vibration to the traditional knife handle. Its core component is piezoelectric ceramics, which use the inverse piezoelectric effect of piezoelectric ceramics to convert electrical energy into mechanical vibration. The working principle of the ultrasonic knife handle is to convert the high-frequency electrical energy provided by the host generator into ultrasonic mechanical vibration energy by the transducer in the handle, and transmit it to the cutter head. When the cutter head needs to be replaced, the movable sleeve 401 is moved to squeeze the support spring 403 and move the movable sleeve 401 to the contact ring 13. At this time, the storage groove 404 on the inner wall of the movable sleeve 401 is connected to the groove body 43, and the cutter head body 4 can be pulled. The movement of the cutter head body 4 pushes the block 44 into the storage groove. The cutter head body 4 can be smoothly taken out of the groove 404 for replacement. Since the two ends of the block 44 are arc-shaped, it is convenient to adjust the movement of the cutter head body 4. Similarly, when the cutter head body 4 needs to be installed, the movable adjustment extrusion support spring 403 should also be moved to put the cutter head body 4 in. The top of the cutter head body 4 will squeeze the block 44 into the storage groove 404, so that the block 44 is flush with the groove 42, and the pull on the movable sleeve 401 is released. Under the push of the support spring 403, the movable sleeve 401 squeezes the block 44 into the groove 42 to fix the cutter head body 4.

[0028] Two guide rods 6 are fixedly mounted on one side of the fixing ring 402, and a guide groove 7 for the guide rods 6 to slide is provided on one side of the mounting seat 2, and the surface of the guide rods 6 is movably sleeved with the inner part of the supporting spring 403;

[0029] Specifically, the guide rod 6 is movably sleeved in the guide groove 7, thereby limiting the movable sleeve 401 to be able to move but not rotate.

[0030] The surface of the clamping block 44 is integrally processed with two limit blocks 8, and the interior of the groove body 43 is connected to a limit groove 9 for the limit blocks 8 to slide;

[0031] Furthermore, a limiting block 8 is integrally processed on the surface of the clamping block 44 , and a limiting groove 9 for the limiting block 8 to slide is opened in the groove body 43 , which has an anti-drop protection effect on the clamping block 44 .

[0032] Two strip blocks 10 are fixedly mounted on the surface of the cutter head body 4, and a strip groove 11 for the strip blocks 10 to slide is provided inside the circular groove 41;

[0033] It is worth noting that two strip blocks 10 are integrally formed on the cutter head body 4 . When the cutter head body 4 is installed, the strip block 10 is placed in the strip groove 11 , so that the groove 42 on the surface of the cutter head body 4 can be smoothly connected and fixed with the block 44 .

[0034] In order to facilitate the adjustment of the movable sleeve 401 , two shifting plates 12 are fixedly mounted on the surface of the movable sleeve 401 .

[0035] In order to facilitate the movement of the movable sleeve 401 and to smoothly align the storage groove 404 with the groove body 43 , a resistance ring 13 for limiting the movable sleeve 401 is fixedly mounted on the surface of the mounting seat 2 .

[0036] The adjustment assembly 5 includes a mounting frame 51 fixedly mounted on the bottom of the ultrasonic knife handle 1, a connecting seat 52 is fixedly mounted on the bottom of the mounting frame 51, an adjusting rod 53 is installed on the internal thread of the connecting seat 52, an assembly plate 54 for rotating the adjusting rod 53 is provided at the bottom of the mounting seat 2, a motor 55 is installed at one end of the adjusting rod 53, and a sliding block 56 is fixedly mounted on the bottom of the mounting frame 51 and slidably mounted on the top of the assembly plate 54;

[0037] It is worth noting that by starting the motor 55 to rotate the electric adjustment rod 53, the connecting seat 52 and the mounting frame 51 can be driven to move, so that the ultrasonic knife handle 1 and the knife head body 4 on the surface of the mounting frame 51 can be moved and adjusted for use.

[0038] When the tool bit needs to be replaced, the movable sleeve 401 is moved to squeeze the support spring 403, and the movable sleeve 401 is moved to abut against the abutting ring 13. At this time, the storage groove 404 on the inner wall of the movable sleeve 401 communicates with the groove body 43, and the tool bit body 4 can be pulled. The movement of the tool bit body 4 pushes the clamping block 44 into the storage groove 404, and the tool bit body 4 can be smoothly taken out for replacement. Since both ends of the clamping block 44 are arc-shaped, it is convenient to adjust the movement of the tool bit body 4. Similarly, when the tool bit body 4 needs to be installed, the movable adjustment also squeezes the support spring 403, the tool bit body 4 is placed, the top of the tool bit body 4 will squeeze the clamping block 44 into the storage groove 404, so that the clamping block 44 is flush with the clamping groove 42, and the pulling of the movable sleeve 401 is released. Under the push of the support spring 403, the movable sleeve 401 squeezes the clamping block 44 into the clamping groove 42 to fix the tool bit body 4.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
