Description

Technical Field

[0001] The utility model relates to the technical field of screw locking machines, in particular to a screw locking machine for an automatic screw locking process. Background Technique

[0002] An automatic screw locking machine realizes automatic processes such as screw conveying, tightening, and detection through various electric and pneumatic components. By using the equipment, the screw fastening process is simplified to reduce the number of workers and the adverse factors caused by human operation errors. It is a typical non-standard automation equipment. Automatic screw locking machines are mainly divided into: handheld screw locking machines, multi-axis automatic screw locking machines, and coordinate automatic screw locking machines. The locking mechanism uses a configured electric screwdriver, pneumatic screwdriver, or servo motor to perform the screw tightening action according to the program setting, completely replacing manual labor;

[0003] The publication number CN 217800110 U discloses a screw locking machine for an automatic screw locking process, including a bottom plate, a workpiece moving mechanism, a horizontal moving mechanism, and also including a feeding mechanism. The workpiece moving mechanism is installed on the upper side of the bottom plate, the feeding mechanism is arranged on the upper side of the workpiece moving mechanism, and the horizontal moving mechanism is installed on the upper side of the feeding mechanism. A conveyor belt feeds screws into a screw chute. By rotating a push plate, screws with their heads facing up are screened and enter a screw clamping block through the screw chute to correct the posture of the screws, facilitating the adsorption and screwing in of the screws;

[0004] When in use, the screws of this device are likely to slide far away due to inertia, making it difficult for the screws to slide into the inner side of the screw clamping block. Moreover, it is difficult to adjust the position of the screws for this device, resulting in some screws abutting against the screwdriver head; Therefore, we propose a screw locking machine for an automatic screw locking process. Content of the Utility Model

[0005] The purpose of the utility model is to provide a screw locking machine for an automatic screw locking process, solving the existing problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

The rocker is rotatably installed outside the clamping frame. The connecting rod is rotatably installed outside the movable block. One end of the connecting rod is rotatably installed outside the rocker. The clamping block is fixedly installed outside the rocker.

[0011] As a further improvement of the above solution, the shape of the clamping frame is C-shaped. A rotating groove is opened on one side of the clamping frame. The rocker is rotatably installed inside the rotating groove.

[0012] By adopting the above technical solution, the rotating groove facilitates the rocker to slide out after being stressed, so that the rocker can drive the clamping block to clamp and fix the screw.

[0013] As a further improvement of the above solution, through grooves are opened at the connection positions of the connecting rod and the movable block with the rocker. A fixed pin is arranged inside the through grooves.

[0014] By adopting the above technical solution, the connection between the connecting rod and the movable block and the rocker is relatively stable, and it is not easy to get out of position.

[0015] As a further improvement of the above solution, a limiting groove is opened on the front side of the fixed frame. The slider is slidably installed inside the limiting groove.

[0016] By adopting the above technical solution, it is difficult for the slider to deviate from its position or rotate along with the lead screw after being stressed, so that the slider can only slide.
