Description

Technical Field

[0001] The present application relates to the technical field of drill bit processing equipment, and in particular to a positioning mechanism for drill bit processing. Background Art

[0002] In the field of plate processing, drill bits are one of the common processing tools. Drill bits can drill through holes or blind holes in solid materials and expand existing holes.

[0003] The drill bit is in the shape of a rod before processing, and after processing and milling, the blade is formed at the end. During the processing and production process, the clamping and centering of the drill bit has a great influence on the production accuracy of the drill bit. The Chinese patent "CN219113849U" discloses a positioning mechanism for drill bit processing when approaching, which realizes the clamping movement through the symmetrical clamping plates on both sides and the screw mechanism, and finally realizes the clamping of drill bits with different diameters; in the clamping process of the columnar drill bit, there is still a certain risk of error when only clamping on both sides. This application aims to make further improvements on this point. Utility Model Content

[0004] The purpose of this application is to provide a positioning mechanism for drill bit processing to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a positioning mechanism for drill bit processing, comprising a base;

[0006] A driving mechanism, a linkage mechanism and a clamping mechanism arranged on the base;

[0007] The clamping mechanism is provided with at least three groups and is connected to the linkage mechanism; the linkage mechanism comprises a linkage ring and a connecting rod, the outer peripheral wall of the linkage ring is provided with a plurality of mounting ears, one end of the connecting rod is hinged to the mounting ear, and the other end is hinged to the clamping mechanism, and the plurality of mounting ears are arranged one by one corresponding to the clamping mechanism;

[0008] A plurality of the clamping mechanisms are arranged around the linkage ring at equal angles, and the driving mechanism is suitable for driving one group of the clamping mechanisms to move radially along the linkage ring;

[0009] It also includes a limiting slide rail, and the clamping mechanism is slidably arranged on the limiting slide rail to move along the radial direction of the linkage ring;

[0010] In the above implementation process, the staff places the drill bit to be processed in the ring body of the linkage ring, and then the driving mechanism drives one group of clamping mechanisms to move along the radial direction of the linkage ring to approach the drill bit. During the movement of one group of mechanisms, it will drive the linkage ring to rotate through the connecting rod, and the rotation of the linkage ring can drive its corresponding clamping mechanism to move through another connecting rod. The clamping mechanism can only move along the radial direction of the linkage ring under the action of the limiting slide rail, and finally realizes the linkage clamping of multiple groups of clamping mechanisms, and clamps the drill bit located in the linkage ring at the same time; in this scheme, multi-angle linkage clamping is adopted, and the drill bit is also automatically centered during the clamping process to ensure the subsequent processing accuracy, and the multi-angle clamping can effectively improve the clamping effect and reduce the risk of deviation; in addition, this scheme only needs to adopt one group of driving mechanisms, and cooperate with the linkage mechanism to realize the linkage clamping of multiple groups of clamping mechanisms, which effectively saves the number of driving mechanisms, reduces costs and ensures the consistency of actions between individual clamping mechanisms; in addition, the positioning mechanism provided by this scheme can be applicable to drill bits of various models, which greatly improves its compatibility.

[0011] Preferably, the clamping mechanism comprises a fixed block slidably arranged on the slide rail and a clamping member detachably arranged on the fixed block;

[0012] In the above implementation process, the fixed block can slide on the slide rail and thereby drive the clamping piece to move; the clamping piece can be detachably arranged on the fixed block, and firstly, fine-tuning can be performed according to actual conditions; secondly, the clamping piece can be replaced and maintained after being used for a period of time; thirdly, when processing drill bits of different models, different clamping pieces can be replaced according to different needs.

[0013] Preferably, the clamping member is rod-shaped, and is conically arranged at one end of the clamping member close to the linkage ring, and the conical end surface is flat;

[0014] In the above implementation process, the tapered end faces of the clamping members can prevent the edges of different clamping members from colliding with each other when they are brought close to each other, and the tapered structure can provide more air avoidance space.

[0015] Specifically, it also includes a positioning seat arranged on the base, the positioning seat is provided with a limiting groove, the limiting groove is coaxially arranged with the linkage ring and is suitable for accommodating a drill bit;

[0016] In the above implementation process, before clamping and positioning, the staff can place the drill bit in the limit groove to achieve preliminary positioning; it is understandable that there is a gap between the limit groove and the drill bit, which only plays a role in preliminary positioning, so that the drill bit can have a relatively stable state before clamping and positioning, thereby ensuring the stability of the subsequent clamping and fixing process.

[0017] Preferably, a receiving groove is provided on the fixing block, and the connecting rod is hinged in the receiving groove.

[0018] Preferably, the driving mechanism comprises a driving cylinder and a driving rod provided at a driving end of the driving cylinder, and the other end of the driving rod is connected to one of the clamping mechanisms;

[0019] In the above implementation process, the driving cylinder drives the driving rod to move, and the moving rod is connected to the fixed block, thereby driving the fixed block to move together.

[0020] Compared with the prior art, the beneficial effects of the present application are as follows: in the present solution, multi-angle linkage clamping is adopted, and the drill bit is also automatically centered during the clamping process to ensure the accuracy of subsequent processing, and the multi-angle clamping can effectively improve the clamping effect and reduce the risk of deviation; in addition, the present solution only needs to adopt one set of driving mechanisms, and cooperate with the linkage mechanism to realize the linkage clamping of multiple sets of clamping mechanisms, which effectively saves the number of driving mechanisms, reduces costs and ensures the consistency of actions between the clamping mechanisms; in addition, the positioning mechanism provided by the present solution can be applicable to various types of drill bits, which greatly improves its compatibility.

[0032] Example

[0033] The drill bit is in the shape of a rod before processing, and after processing and milling, the blade is formed at the end. During the processing and production process, the clamping and centering of the drill bit has a great influence on the production accuracy of the drill bit. The Chinese patent "CN219113849U" discloses a positioning mechanism for drill bit processing when approaching, which realizes the clamping movement through the symmetrical clamping plates on both sides and the screw mechanism, and finally realizes the clamping of drill bits with different diameters; in the clamping process of the columnar drill bit, there is still a certain risk of error when only clamping on both sides. This application aims to make further improvements on this point; in order to solve the above technical problems, this embodiment provides the following technical solutions:

[0034] For details, see Figure 1-2 , this embodiment provides a positioning mechanism for drill bit processing, including a base 10, a driving mechanism 20, a linkage mechanism 30 and a clamping mechanism 50 arranged on the base 10;

[0035] Specifically, the clamping mechanism 50 is provided with at least three groups and is connected to the linkage mechanism 30;

[0036] Specifically, the linkage mechanism 30 includes a linkage ring 31 and a connecting rod 32. The outer peripheral wall of the linkage ring 31 is provided with a plurality of mounting ears 311. One end of the connecting rod 32 is hinged to the mounting ear 311, and the other end is hinged to the clamping mechanism 50. The plurality of mounting ears 311 are arranged one by one corresponding to the clamping mechanism 50.

[0037] Further, a plurality of clamping mechanisms 50 are arranged around the linkage ring 31 at equal angles, and the driving mechanism 20 is adapted to drive one group of the clamping mechanisms 50 to move radially along the linkage ring 31;

[0038] Furthermore, it also includes a limiting slide rail 40, and the clamping mechanism 50 is slidably disposed on the limiting slide rail 40 to move along the radial direction of the linkage ring 31;

[0039] In the above scheme, the staff places the drill bit to be processed in the ring body of the linkage ring 31, and then the driving mechanism 20 drives one group of clamping mechanisms 50 to move along the radial direction of the linkage ring 31 to approach the drill bit. During the movement of one group of mechanisms, it will drive the linkage ring 31 to rotate through the connecting rod 32, and the rotation of the linkage ring 31 can drive the corresponding clamping mechanism 50 to move through another connecting rod 32. The clamping mechanism 50 can only move along the radial direction of the linkage ring 31 under the action of the limiting slide rail 40, and finally realizes the linkage clamping of multiple groups of clamping mechanisms 50, and at the same time, the drill bit located in the linkage ring 31 is clamped. To achieve clamping; in this solution, multi-angle linkage clamping is adopted, and the drill bit is also automatically centered during the clamping process to ensure the accuracy of subsequent processing, and the multi-angle clamping can effectively improve the clamping effect and reduce the risk of deviation; in addition, this solution only needs to adopt one set of driving mechanism 20, and cooperate with the linkage mechanism 30 to achieve the linkage clamping of multiple sets of clamping mechanisms 50, which effectively saves the number of driving mechanisms 20, reduces costs and ensures the consistency of actions between the clamping mechanisms 50; in addition, the positioning mechanism provided by this solution can be applicable to various types of drill bits, which greatly improves its compatibility.

[0040] Specifically, the clamping mechanism 50 includes a fixed block 52 slidably disposed on the slide rail 40 and a clamping member 51 detachably disposed on the fixed block 52;

[0041] In the above scheme, the fixed block 52 can slide on the slide rail 40 and thereby drive the clamping member 51 to move; the clamping member 51 can be detachably arranged on the fixed block 52, and firstly, fine-tuning can be performed according to actual conditions; secondly, the clamping member 51 can be replaced and maintained after being used for a period of time; thirdly, when processing drill bits of different models, different clamping members 51 can be replaced according to different needs.

[0042] Furthermore, the above-mentioned detachable manner may be a detachable manner using screws and mounting holes;

[0043] Furthermore, the mounting hole may be a waist-shaped hole, and the opening direction of the waist-shaped hole is parallel to the clamping direction thereof.

[0044] Specifically, the clamping member 51 is rod-shaped, and one end of the clamping member 51 close to the linkage ring 31 is conical, and the conical end surface is flat;

[0045] In the above solution, the end faces of the clamping members 51 are tapered to avoid collisions between the edges of different clamping members 51 when the clamping members 51 are brought close to each other, and the tapered structure can provide more air-avoiding space.

[0046] Specifically, it also includes a positioning seat 60 arranged on the base 10, the positioning seat 60 is provided with a limiting groove, the limiting groove is coaxially arranged with the linkage ring 31 and is suitable for accommodating the drill bit;

[0047] In the above scheme, before clamping and positioning, the staff can place the drill bit in the limit groove to achieve preliminary positioning; it is understandable that there is a gap between the limit groove and the drill bit, which only plays a role in preliminary positioning, so that the drill bit can have a relatively stable state before clamping and positioning, thereby ensuring the stability of the subsequent clamping and fixing process.

[0048] For details, see Figure 2 A receiving groove 521 is provided on the fixing block 52 , and the connecting rod 32 is hingedly connected to the receiving groove 521 .

[0049] Furthermore, the driving mechanism 20 includes a driving cylinder 21 and a driving rod 22 disposed at a driving end of the driving cylinder 21, and the other end of the driving rod 22 is connected to one of the clamping mechanisms 50;

[0050] In the above solution, the driving cylinder 21 drives the driving rod 22 to move, and the moving rod is connected to the fixed block 52, thereby driving the fixed block 52 to move together.

[0051] It is understandable that in other embodiments, the driving mechanism 20 can also be in the form of a servo motor and a screw; wherein the driving stroke of the servo motor is more controllable, and thus the movement distance of the clamping mechanism 50 can be better controlled in conjunction with the screw. Thus, when producing and processing different products, the movement of the clamping mechanism 50 can be controlled by adjusting the rotation of the servo motor, thereby ultimately achieving precise clamping.

[0052] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0053] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
