Description

Technical Field

[0001] The utility model relates to the technical field of jigs, and specifically relates to a jig for machining holes of fasteners. Background Technique

[0002] The machining of fastener holes is an essential link in the manufacturing process of fasteners. It mainly involves drilling, which is one of the common machining methods in fastener processing. The raw material is drilled by a drilling machine to meet the installation and use requirements.

[0003] During the drilling process, it is necessary to pay attention to controlling the accuracy of the drilling depth and diameter to avoid deviations. The application of jigs can significantly improve the machining efficiency. When using a jig to clamp the workpiece, the workpiece can be quickly positioned and clamped without alignment, effectively saving the time of auxiliary work, thereby improving the work efficiency of the operator.

[0004] The prior art patent document with the publication number CN216228098U provides a jig for machining the center holes of fasteners. This jig can be installed on an automated production line, fix the fastener nail and drive the fastener nail to transfer between various processes. The fastener nail is fixed by an upper fixing block and a lower fixing block. The fastener nail completes the machining of each process under the fixation of the jig and transfers between various processes. When the upper fixing block is separated from the lower fixing block, it can drive the ejector rod to move upward, thereby ejecting the processed part therein to complete the unloading operation. The operation is convenient and the efficiency is high.

[0005] In the above prior art, although the jig is fixed by the upper fixing block and the lower fixing block, and the fastener nail completes the machining of each process under the fixation of the jig, however, the jig in this patented technology can only clamp and fix the fastener nail. If it is other-shaped fasteners, it cannot clamp and fix them well, thereby reducing the applicability of the jig, being unable to meet the clamping requirements of different fasteners, and reducing the practicability. Therefore, we need a jig for machining holes of fasteners. Content of the Utility Model

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A fixture for machining fastener holes, including an equipment plate 1.

A sliding rod 606 is fixedly connected to the top of the equipment plate 1.

[0029] Through the above technical solution, by pulling the pull rod 308 downward, the positioning rod 305 can be disengaged from the positioning groove 304, releasing the limit fixation of the mounting block 302. After that, the mounting block 302 on one side of the clamping block 303 can be pulled out of the mounting groove 301 for replacement. The clamping block 303 matching the shape of different fasteners is replaced. The mounting block 302 on one side of the clamping block 303 is reinserted into the mounting groove 301 for connection. By releasing the pull rod 308, the positioning rod 305 at the top of the baffle 306 can be inserted into the positioning groove 304 under the action of the spring 307 to limit and fix the mounting block 302, completing the replacement of the clamping block 303. The clamping block 303 can be replaced as needed to meet the clamping work of different fasteners, improving the applicability of the fixture.

[0030] Specifically, a fixing groove 5 is opened at the top of the fixing frame 4.

[0031] Through the above technical solution, the number of the fixing grooves 5 is multiple, and the multiple fixing grooves 5 are arranged at equal distances.

[0032] Specifically, the mounting plate 2 and the mounting block 302 form a clamping structure through the mounting groove 301, and the shape and size of the mounting groove 301 match the shape and size of the mounting block 302.

[0033] Through the above technical solution, it is convenient for the clamping block 303 on one side of the mounting plate 2 to extend into the mounting groove 301 through the mounting block 302 for connection, so that the mounting plate 2 and the clamping block 303 can be disassembled and installed.

[0034] Specifically, the mounting block 302 and the positioning rod 305 form a clamping structure through the positioning groove 304, and the shape and size of the positioning groove 304 match the shape and size of the positioning rod 305.

[0035] Through the above technical solution, it is convenient for the mounting block 302 to extend into the positioning groove 304 through the positioning rod 305 to limit and fix it, and the positioning rod 305 extends upward under the action of the spring 307, having an elastic pressure, to complete the limit and fixation of the mounting block 302.

[0036] Specifically, the positioning rod 305 and the pull rod 308 form a fixed structure through the baffle 306, and the baffle 306 is arranged between the positioning rod 305 and the pull rod 308, and one end of the pull rod 308 penetrates through the spring 307 to be connected with the baffle 306.

[0037] Through the above technical solution, it is convenient to pull the pull rod 308 by hand to drive the positioning rod 305 on one side of the baffle 306 to disengage from the positioning groove 304, release the limit fixation of the mounting block 302, and then the clamping block 303 can be quickly disassembled.

[0038] Specifically, the first motor 601 and the moving block 603 form a moving structure through the lead screw 602, and the thread directions on both sides of the lead screw 602 are opposite, and the number of the moving blocks 603 is two.

[0039] Through the above technical solution, it is convenient to start the first motor 601 to drive the lead screw 602 to rotate and drive the moving block 603 to move at the same time. Since the thread directions on both sides of the lead screw 602 are opposite, and the two moving blocks 603 are symmetrically arranged on both sides of the lead screw 602, then the rotation of the lead screw 602 drives the two moving blocks 603 to move relatively, and the mounting plate 2 at the bottom of the moving block 603 can be driven to move inward to clamp and fix the fastener.

[0040] Specifically, the second motor 604 and the equipment plate 1 form a rotating structure through the connecting rod 605, and the connecting rod 605 is arranged between the second motor 604 and the equipment plate 1, and the number of the slide rods 606 is two.

[0041] Through the above technical solution, it is convenient to start the second motor 604 to drive the connecting rod 605 to rotate and drive the equipment plate 1 to rotate, and then drive the fastener clamped and fixed at the bottom to rotate, facilitating the rotation and adjustment of the direction of the fastener. Moreover, during the rotation of the equipment plate 1, the sliding rod 606 will slide synchronously at the bottom of the fixed frame 4 to maintain stability.

[0042] Working principle: When using the fixture for machining fastener holes, first, when replacing the clamping block 303, first pull the pull rod 308 downward. The pull rod 308 can drive the positioning rod 305 on one side of the baffle 306 to disengage from the positioning groove 304, releasing the limit fixation of the mounting block 302. Then pull the clamping block 303 outwards to complete the disassembly of the clamping block 303. Reinstall the clamping block 303 corresponding to the fastener, insert the mounting block 302 on one side of the clamping block 303 into the positioning groove 304 for connection, and then release the pull rod 308. The baffle 306 moves upward under the action of the spring 307, causing the positioning rod 305 to extend into the positioning groove 304 to limit and fix the mounting block 302, completing the installation of the clamping block 303. Then start the first motor 601. The first motor 601 drives the lead screw 602 to rotate, and the lead screw 602 drives the two moving blocks 603 to move inwards. The two moving blocks 603 drive the clamping block 303 on the mounting plate 2 to clamp and fix the fastener. When the angle of the fastener needs to be adjusted, start the second motor 604. The second motor 604 can drive the connecting rod 605 to rotate, and the connecting rod 605 drives the equipment plate 1 to rotate. Moreover, during the rotation of the equipment plate 1, the sliding rod 606 will slide synchronously at the bottom of the fixed frame 4 to maintain stability, completing the rotation and adjustment of the direction of the fastener. This completes all the work. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
