Description

Technical Field

[0001] The present invention relates to the technical field of connector clamping, and in particular to a connector processing jig. Background Art

[0002] The clamping fixture is used to assist in the processing of the connector ejector pin, such as the manual circular grinding process. The existing clamping fixtures need to be repeatedly calibrated when processing the ejector pin, which makes the clamping and positioning efficiency low, the precision low, and the clamping process cumbersome, and does not have the ability to be used in combination. For example, CN208163132U discloses a long ejector pin clamping and positioning fixture, which clamps the connector ejector pin from both sides through a clamping plate and a clamping plate, and the clamping and positioning efficiency is low and the process is cumbersome.

[0003] Therefore, there is a need for a processing jig for clamping ejector pins that is convenient for processing ejector pins with high repetitiveness. Summary of the invention

[0004] The purpose of the present invention is to provide a connector processing jig in order to overcome the defects of the above-mentioned prior art. This product is provided with a fixed seat, a clamping screw, a fixing screw, a first clamping block, a second clamping block, and an elastic member, and the tightness of the clamping can be adjusted by adjusting the clamping screw or the fixing screw.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The object of the present invention is to provide a connector processing jig for clamping a connector ejector pin to be processed, the connector processing jig comprising a fixing seat, a clamping screw, a fixing screw, a first clamping block, a second clamping block, and an elastic member; the clamping screw is connected to the fixing seat; the fixing screw passes through the fixing seat; the first clamping block is connected to the clamping screw; the second clamping block is connected to the fixing screw; the elastic member is arranged between the first clamping block and the second clamping block.

[0007] Furthermore, two fixing screws are provided, and the two fixing screws are respectively provided on both sides of the clamping screw.

[0008] Furthermore, the fixing seat is provided with a threaded hole; the clamping screw is connected to the threaded hole of the fixing seat through a thread; the fixing seat is provided with a through hole; the fixing screw passes through the through hole of the fixing seat.

[0009] Furthermore, the elastic member is sleeved outside the fixing screw; the fixing screw passes through the fixing seat, the first clamping block, the elastic member in sequence from top to bottom and is connected to the second clamping block.

[0010] Furthermore, the elastic member is a spring, the upper end of the spring is connected to the first pressing block, and the lower end of the spring is connected to the second pressing block.

[0011] Furthermore, the fixing seat includes a V-shaped positioning groove; the V-shaped positioning groove is arranged below the second pressing block.

[0012] Furthermore, two side surfaces of the V-shaped positioning groove are planes, and the angle between the two side surfaces is 90°.

[0013] Furthermore, the bottom surface of the second pressing block is an arc surface to better match the shape of the connector ejector pin to be processed.

[0014] Furthermore, the bottom of the clamping screw abuts against the first clamping block.

[0015] Furthermore, the fixing screw includes a head and a tail connected to the head, and the tail passes through the fixing seat.

[0016] Optionally, the bottom of the clamping screw is connected to the first clamping block via a bearing; the bearing is interference fit with the clamping screw, and the bearing is interference fit with the first clamping block. The bearing connection can further relatively limit the connection between the clamping screw and the first clamping block in a natural state (without clamping the connector ejector pin to be processed, and without applying an upward pulling force to the fixing screw), thereby avoiding the situation where the fixing screw needs to rely on a fixing seat or a V-shaped positioning groove for limiting.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) The connector processing jig provided by the technical solution is easy to clamp: the tools used in the past need to spend a lot of time to calibrate, while the jig of the present application only needs to be put on, saving a lot of clamping time.

[0019] 2) The technical solution provides a connector processing jig that is easy to process: previous tooling fixtures were large in size and very cumbersome during calibration and processing, while this fixture is smaller in size and more convenient for machine tool processing.

[0020] 3) The connector processing jig provided by the technical solution is convenient for repeated processing: the base is fixed, which is convenient for repeated processing.

[0021] 4) The connector processing jig provided by the technical solution is easy to operate: the workpiece can be clamped by only twisting the clamping screw or pulling the fixing screw, and the tightness can be adjusted easily. BRIEF DESCRIPTION OF THE DRAWINGS
