Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a grinding and positioning assembly for machinery parts. Background Art

[0002] Machinery is a tool device that can help people reduce the difficulty of work or save effort. Items such as chopsticks, brooms and tweezers can be called machinery. They are simple machines, and complex machinery is composed of two or more simple machines. These more complex machines are usually called machines. From the perspective of structure and movement, there is no difference between mechanisms and machines. They are generally called machinery. 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, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of the machine. Other processes are called auxiliary processes, such as transportation, storage, power supply, equipment maintenance, etc. The process is composed of one or several sequentially arranged processes, and a process consists of several steps.

[0003] Patent announcement number CN220051373U discloses a mechanical parts grinding and positioning assembly, including a base, a vertical plate and a shell are fixedly installed on the upper surface of the base, a motor is fixedly installed on one side of the vertical plate, a grinding disc is fixedly installed on the output shaft of the motor, a cavity is opened on the upper surface of the shell, a spring is fixedly installed on the inner bottom wall of the cavity, the top of the spring is fixedly connected through a slide, and a shift rod is fixedly installed on one side of the slide. The mechanical parts grinding and positioning assembly is placed on the inner wall of the fixed plate by loosening the screw, and then the screw drives the arc plate to move, so that the part to be polished is placed on the inner wall of the fixed plate, and the screw is tightened so that the screw drives the arc plate to clamp the part, and then the screw is loosened to move the slide downward, thereby tightening the screw so that the screw performs a limit operation on the slide, and in the process of the motor rotating and driving the grinding disc to rotate, the grinding disc is polished, which is convenient for the staff to use and improves the use efficiency of the positioning assembly.
