Technical Field

[0001] The utility model relates to the technical field of assembly devices, and particularly relates to a lock piece assembly device. Background Art

[0002] During the production process of wire harnesses, the lock pieces in the connectors need to fix the terminals. However, the manufacturer does not design various test jigs according to the corresponding wire harness types. After fixing the connector, the terminals are pressed into the connector. For example, the utility model patent with the publication number CN206774863U discloses a lock piece assembly device, which includes a fixer, a lock piece pressing device and a power cord. The fixer is fixedly connected to the lock piece pressing device, and a fixing groove is arranged on the fixer, which corresponds to the outer sheath of the connector to be assembled. The lock piece pressing device includes a lock piece pressing head corresponding to the position of the fixing groove, and the lock piece pressing head corresponds to the lock piece of the connector to be assembled. This patent fixes the connector through the fixer and presses the lock piece through the lock piece pressing head on the lock piece pressing device, so that the lock piece can be pressed in place, ensuring the stability of the lock piece assembly and improving the production efficiency and yield.

[0003] When the existing lock piece assembly device is in use, once the lock piece is skewed after being placed in the connector, it will cause the bending of the lock piece and then be scrapped. And the lock piece is easily pressed too far, which will also lead to the scrapping of the connector. Therefore, improvement is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a lock piece assembly device, which solves the problem that when the existing lock piece assembly device is in use, once the lock piece is skewed after being placed in the connector, it will cause the bending of the lock piece and then be scrapped, and the lock piece is easily pressed too far, which will also lead to the scrapping of the connector.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a lock piece assembly device, including a base, a mold is placed in the middle of the upper end of the base, a boss is fixedly connected inside the mold, a connector is slidably connected inside the mold, and the connector contacts the boss.

A bidirectional screw is installed inside the base through a bearing. A moving block is threadedly connected to the threaded part of the bidirectional screw, and the moving block is slidably connected to the inside of the base. A inserting piece is fixedly connected to one side of the moving block close to the positioning block, and the inserting piece is inserted into the positioning block. The moving block can move horizontally through the threaded cooperation with the bidirectional screw, so that the inserting piece on the moving block is inserted into the positioning block at the bottom of the mold. In this way, only by controlling the movement of the moving block can the disassembly and assembly of the mold be completed.

[0009] Preferably, a knob is fixedly connected to one end of the bidirectional screw located outside the base, and the knob is made of plastic. Through the setting of the knob, it is convenient to rotate the bidirectional screw.

[0012] 1. By designing the connector mold, the head of the connector sinks into the mold, playing a positioning role, and having a small movement margin in the mold. Moreover, corresponding to the pressing position of the lock piece, a convex platform is designed to limit the downward pressing stroke of the lock piece, preventing the downward pressing stroke of the lock piece from being excessive and damaging the connector. Finally, a stop block is installed on the back of the mold to prevent the head of the lock piece from being bent due to excessive downward pressing of the lock piece when the lock piece is pressed into the device, playing a protective role.

[0013] 2. By arranging a positioning block at the bottom of the mold, the positioning block can be inserted into the base, and then by rotating the bidirectional screw, the moving block moves horizontally, so that the inserting piece on the moving block is inserted into the positioning block at the bottom of the mold. In this way, only by controlling the movement of the moving block can the disassembly and assembly of the mold be completed. BRIEF DESCRIPTION OF THE DRAWINGS

Through the setting of the stop block 5, when the device presses in the lock piece 4, it prevents the lock piece 4 from being pressed down excessively, resulting in the bending of the head of the lock piece 4, playing a protective role. A boss 6 is fixedly connected inside the tooling 2. A connector 3 is slidably connected inside the tooling 2, and the connector 3 contacts the boss 6. A lock piece 4 is inserted into the connector 3, and the bottom of the lock piece 4 contacts the boss 6.

A slide rail 8 is fixedly connected to the front of the back plate 7 and below the support plate 11. A slider 9 is slidably connected inside the slide rail 8, and the slider 9 is connected to the press-in block 10 by a bolt. Through the setting of the slide rail 8 and the slider 9, it has a guiding effect on the lifting of the press-in block 10.

[0022] Please refer to Figure 4, a positioning block 15 is fixedly connected to the bottom of the tooling 2, and the positioning block 15 is inserted into the base 1. A bidirectional screw 13 is installed inside the base 1 through a bearing. One end of the bidirectional screw 13 located outside the base 1 is fixedly connected to a knob 14, and the knob 14 is made of plastic. Through the setting of the knob 14, it is convenient to rotate the bidirectional screw 13. The threaded part of the bidirectional screw 13 is threadedly connected to a moving block 16, and the moving block 16 is slidably connected to the inner side of the base 1. One side of the moving block 16 close to the positioning block 15 is fixedly connected to an insertion piece 17, and the insertion piece 17 is inserted into the positioning block 15. A ball 18 is arranged at the bottom of the moving block 16, and the ball 18 is slidably connected to the inner surface of the base 1.
