Description

Technical Field

[0001] This utility model relates to the field of feeding technology for pin processing, and in particular to a feeding mechanism for precision cylindrical threaded pin processing. Background Technology

[0002] A cylindrical threaded pin is a specially designed pin that combines the basic structural features of a cylindrical pin with the advantages of a threaded connection. Specifically, this type of pin is typically cylindrical with threads machined onto its surface. However, current feeding mechanisms cannot adjust the feed chute to accommodate the size of the cylindrical threaded pin, and this can cause wear on the pin during feeding, resulting in material waste, increased equipment costs, and reduced production efficiency. Therefore, improvements are urgently needed. Utility Model Content

[0016] Two fixing plates are provided, and the two fixing plates are fixedly installed on the second support column. The fixing plates are fixedly connected to the support plate.

[0017] Preferably, the starting mechanism includes:

[0018] A first motor is mounted on the fixed plate and fixedly connected to the fixed plate;

[0019] A first rotating roller is disposed on the fixed plate and rotatably connected to the fixed plate. One end of the first rotating roller is fixedly connected to the output end of the first motor.

[0020] Preferably, the conveying mechanism includes:

[0021] Multiple conveyor plates are provided, and the multiple conveyor plates are arranged on the moving guide rail and connected to the sliding rod of the moving guide rail;

This allows the spring to automatically adjust its length according to the actual pin diameter, making it adaptable to pins of different sizes without the need to replace or manually adjust the feeding chute. The elastic mechanism reduces friction between the pin and the conveying mechanism, and also reduces the impact force when the pin enters the limiting groove, thereby reducing damage caused by scratches, wear, and impacts, and reducing material waste.

[0052] During operation, the first motor 9 is started, which drives the first rotating roller 10 fixedly connected to it to rotate. The first rotating roller 10 is used to drive the transmission belt 5 to rotate, thereby driving the conveying mechanism and the elastic mechanism to rotate, thus realizing the conveying of the cylindrical threaded pin.

[0053] An auxiliary roller 4 is mounted on the support mechanism and rotatably connected to the support mechanism; it is used to assist the stable rotation of the transmission belt 5.
