Description

Technical Field

[0001] The utility model belongs to the technical field of connector processing, and specifically relates to a multi-equal-part precision extrusion mechanism. Background Technique

[0002] When some existing connectors are assembled, it is necessary to insert a copper part into the connector body. In order to prevent the copper part from falling out of the connector body, it is necessary to perform extrusion and necking on one end of the connector body.

[0003] In the past, manual necking was carried out through special necking tools, which required a large amount of labor intensity for operators. Due to different operating forces, the necking sizes would be different, resulting in poor product consistency. If the operation is improper, it is easy to cause product scrapping. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique, the utility model provides a multi-equal-part precision extrusion mechanism that can greatly reduce the labor intensity of workers and improve product quality.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A multi-equal-part precision extrusion mechanism includes a support, a stepping motor arranged on the support, a lifting cylinder, and a multi-equal-part extrusion assembly connected to the stepping motor and the lifting cylinder;

[0007] The multi-equal-part extrusion assembly includes a guide disk, a guide sleeve, and extrusion strips. The guide disk is connected to the lifting cylinder, and the lifting cylinder can drive the guide disk to move up and down. There are multiple extrusion strips, which are slidably connected to the bottom end of the guide disk and are evenly distributed along the bottom end of the guide disk. One end of the extrusion strip converges towards the center of the guide disk, and the other end extends outside the guide disk. The guide sleeve is connected to the stepping motor, and the stepping motor can drive the guide sleeve to rotate axially. The guide sleeve is sleeved outside the guide disk, and one end of the extrusion strip abuts against the inner wall of the guide sleeve. Multiple arc-shaped guide grooves for the sliding of one end of the multiple extrusion strips are provided on the inner wall of the guide sleeve, and the depth of the arc-shaped guide grooves gradually decreases from one end to the other end. When the stepping motor drives the guide sleeve to rotate, it can push each extrusion strip to slide along the guide disk towards the center, so as to extrude the workpiece at the center of the guide disk.

[0008] In order to facilitate product positioning, a positioning column perpendicular to its surface is fixed at the center of the bottom end of the guide disk.

[0009] In order to facilitate the installation of each extrusion strip and at the same time guide and limit the extrusion strip, a plurality of equalizing plates are fixed on the bottom end surface of the guide disk, and an extrusion strip is arranged between adjacent two equalizing plates.

[0010] To facilitate driving the movement of each extrusion bar, a roller is rotatably connected to the end of the extrusion bar extending outside the guide disc, and the roller abuts against the inner wall of the guide sleeve.

[0011] To accurately sense whether each extrusion bar is in place for extrusion, the stepping motor is connected to the guide sleeve through a turntable. A photoelectric switch is provided at one end of the stepping motor, and a sensing piece capable of sensing with the photoelectric switch is fixed at one end of the turntable.

[0012] The beneficial effects of the present utility model: This multi-equal-part precision extrusion mechanism can perform extrusion necking on the end of the connector by driving each extrusion bar to move inward, so that the internal copper parts are relatively fixed to the connector and will not fall out of the connector. Compared with manual necking, the present utility model greatly reduces the labor intensity of operators, improves the processing efficiency, ensures the product quality, and reduces the production cost.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0017] As Figure 1 shown, a multi-equal-part precision extrusion mechanism includes a support 1, a stepping motor 2 provided on the support 1, a lifting cylinder 3, and a multi-equal-part extrusion assembly 4 connected to the stepping motor 2 and the lifting cylinder 3;

[0018] Specifically, in combination with Figure 2 , Figure 3As shown, the multi-equal-part extrusion assembly includes a guide disk 401, a guide sleeve 402, and extrusion bars 403. The guide disk 401 is connected to the lifting cylinder 3 through a coupling. The lifting cylinder 3 can drive the guide disk 401 to move up and down. A positioning post 405 perpendicular to its surface is fixed at the center of the bottom end of the guide disk 401. The positioning post 405 can be inserted into the connector 5 to position the connector. There are six extrusion bars 403, which are slidably connected to the bottom end of the guide disk 401. The extrusion bars 403 are evenly distributed along the bottom end of the guide disk 401 and are parallel to the horizontal plane. Six equalizing plates 404 are fixed to the bottom end surface of the guide disk 401. An extrusion bar 403 is arranged between two adjacent equalizing plates 404. The equalizing plates 404 can limit and guide the extrusion bars 403. One end (inner end) of the extrusion bar 403 converges towards the center of the guide disk 401, and the other end (outer end) extends outside the guide disk 401 and is rotatably connected with a roller 406. The guide sleeve 402 is connected to the stepping motor 2 through a turntable 6. The stepping motor 2 can drive the guide sleeve 402 to rotate axially. A photoelectric switch 8 is arranged at the bottom end of the stepping motor 2. An induction piece 7 capable of sensing with the photoelectric switch 8 is fixed at one end of the turntable 6. The guide sleeve 402 is sleeved outside the guide disk 401. The rollers 406 at the outer ends of the extrusion bars 403 are abutted against the inner wall of the guide sleeve 402. A plurality of arc-shaped guide grooves 407 for the rollers 406 of the plurality of extrusion bars 403 to slide are formed in the inner wall of the guide sleeve 402, and the depth of the arc-shaped guide grooves 407 gradually decreases from one end to the other end.

[0019] During processing, the connector 5 is positioned by a fixture. The lifting cylinder 3 drives the guide disk 401 to descend so that the positioning post 405 is inserted into the connector 5 for positioning. Then, the stepping motor 2 drives the 402 to rotate. Due to the action of the arc-shaped guide grooves 407, each extrusion bar 403 is pushed by the guide sleeve 402 and gradually moves inward along the guide disk 401. Then, the inner ends of the extrusion bars 403 can squeeze and compress the mouth of the connector 5. When the photoelectric switch 8 senses the induction piece 7, the stepping motor 2 stops operating, and the squeezing and compressing of the connector 5 is completed.

[0020] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
