Description

A clamping device for machining mechanical parts

Technical Field

The utility model relates to the technical field of mechanical processing, in particular to a clamping device for processing mechanical parts.

Background Art

Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical equipment. It can be divided into cutting and pressure processing according to the difference in processing methods. In the production process, any process that changes the shape, size, position and properties of the production object to make it a finished product or semi-finished product is called a process. It is the main part of the production process. The process can be divided into casting, forging, stamping, welding, machining and assembly processes. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of the machine. In the processing of mechanical accessories, fixtures are often used to fix the mechanical accessories so that they can be better processed.

After searching the publication (announcement) number: CN217122934U, a clamping device for machining mechanical parts is disclosed, which belongs to the field of mechanical technology. A clamping device for machining mechanical parts includes a fixed seat, a limit groove is provided on the top surface of the fixed seat, two movable plates are arranged in a symmetrical structure on the top surface of the fixed seat, a limit block is fixed on the bottom surface of the movable plate, a slot is provided on the inner side of the movable plate, a clamping piece is screwed in the slot, two prisms are arranged in a symmetrical structure between the two movable plates, an extrusion plate is fixed between the right ends of the two prisms, a movable groove is provided on the bottom surface of the fixed seat, a mounting plate is screwed in the movable groove, a rotating shaft is rotatably connected to the top surface of the mounting plate, a semi-ring worm gear is fixed on the lower part of the rotating shaft, a worm is provided on the outer side of the semi-ring worm gear, and a cam is fixed on the upper part of the rotating shaft. The utility model can quickly separate the two movable plates through a spring, so that the reaction of parts processing and replacement is faster.

During use of the above invention, when it is necessary to clamp the product, the worm is rotated clockwise, and the worm is meshed with the semi-ring worm gear for transmission, thereby driving the cam to squeeze the moving plate on the right and the extrusion plate to be relatively separated. At this time, the extrusion plate pulls the moving plate on the left and the moving plate on the right relatively close through the prism. However, as the moving plate on the right moves to the left, the spring will be compressed. As the degree of compression of the spring increases, the force generated by the spring will be greater, and the user will need to use greater force to rotate the worm, which consumes more physical energy.

To this end, we propose a clamping device for machining mechanical parts.
