Description

Technical Field

[0001] The utility model relates to the technical field of pin shaft processing, in particular to a grinding machine for pin shaft processing. Background Art

[0002] Pins are a type of standardized fasteners that can be used for static fixed connections or for relative movement with the connected parts. They are mainly used at the hinges of two parts to form hinge connections. Pins are usually locked with cotter pins, which are reliable and easy to disassemble. During the manufacturing process, pins need to be polished using a grinder.

[0003] For example, the patent number: CN 211992488 U discloses a grinding machine for processing pin shafts. The application states: "In the prior art, the grinding machine for processing pin shafts usually uses manual hand-held grinding operation when grinding the pin shafts. This practice not only requires workers to have high work experience, but also has certain safety hazards. Once the operation is wrong, it will cause safety accidents such as finger scratches." Although the application solves this problem, it has the following defects:

[0004] The above-mentioned existing technical solutions have the following defects: although the above-mentioned grinder avoids direct contact between the worker's palm and the pin shaft, thereby improving the safety of the grinding process, it is necessary to keep the distance between the grinding wheel and the pin shaft unchanged during the grinding process, which places high requirements on the grinder. It is necessary to hold the slider steadily by hand for a long time to keep its position unchanged and prevent the slider from sliding in the slide groove. This is difficult to achieve. Therefore, we propose a new type of grinder for pin shaft processing.
