Description

Technical Field

[0002] The screw locking machine, also called the automatic screw locking machine, is a device that uses various electric and pneumatic components to realize the automatic conveying, tightening, and detection of screws. It can simplify the screw tightening process, reduce the number of labor and the adverse factors caused by manual misoperation. It is a typical non-standard automation equipment. The automatic screw locking machine is mainly composed of an automatic nail feeding machine, a locking mechanism, a power supply electrical box, a positioning system, and other parts. The automatic nail feeding machine is responsible for the screening, arrangement, detection, material distribution, and conveying of screws; the locking mechanism performs the screw tightening action according to the program settings through the configured electric screwdriver, air screwdriver, or servo motor. The existing screw locking machine can only lock the screws on one side of the product when working. When it is necessary to lock the screws on the other sides of the product, it can only be achieved by manually flipping the product. The use is not flexible enough and reduces work efficiency.

[0003] For example, a screw locking machine disclosed in a Chinese patent document (Announcement No.: CN210388239U) can fix the product by placing the product between the first fixed block and the second fixed block, closing the limit rod, and engaging the lock buckle with the limit rod. The motor drives the fixing seat to flip through the rotating shaft, thereby flipping the product on the fixing seat, and then tightening the screws. There is no need for manual flipping, and the application is flexible, which greatly improves work efficiency.

[0004] However, since the lower end of the workpiece is in contact with the top of the fixing seat, the product still needs to be disassembled and re-fixed when locking the screws at the bottom of the product. The operation is cumbersome, resulting in reduced work efficiency, and the limit rod can only fix and limit products of a specific size, which greatly reduces the problem of product processing range.

A rotating rod 76 is installed on the inner wall of the mounting hole 75 through a bearing. One end of the rotating rod 76 is fixedly connected to a fixed clamping block 77. The second servo electric cylinder 73 squeezes one end of the product through the movable clamping block 74, and cooperates with the fixed clamping block 77 to clamp and fix the product.

[0029] Furthermore, the other end of the rotating rod 76 is fixedly connected to a driving wheel 78, the outer surface of the driving wheel 78 is provided with arc-shaped limiting grooves 79 distributed in a ring array, the outer surface of the driving wheel 78 is provided with toggle grooves 710 distributed in a ring array, and a second servo motor 711 is fixedly installed on the other side surface of the moving seat 7, and the rotation of the driving wheel 78 drives the rotating rod 76 to rotate for positioning.

[0033] Working principle: Step 1, place the product to be processed on the support plate 72, and then start the piston rod of the second servo electric cylinder 73 to extend, one end of the piston rod of the second servo electric cylinder 73 drives the mobile clamping block 74 to squeeze one end of the product, so that the other end of the product is in contact with the fixed clamping block 77 for squeezing, thereby clamping and fixing the product, at this time start the first servo motor 4 to work, the first servo motor 4 drives the screw rod 5 to rotate, the rotation of the screw rod 5 drives the thread block 6 to move through the limit of the moving groove 3, and the movement of the thread block 6 drives the moving seat 7 to move, thereby driving the clamped product to move to the bottom of the thread locking machine body 2;
