Description

Technical Field

[0001] The utility model belongs to the technical field of connecting rod part grinding, in particular to a clamping device for connecting rod part grinding. Background Art

[0002] According to the published patent with announcement number CN215617020U, a burr grinding device for automobile connecting rods ensures grinding accuracy while improving efficiency, has a simple and reliable structure, and is easy to transport. However, there are still the following shortcomings, such as:

[0003] When clamping the connecting rod part, the device clamps it from the top of the connecting rod through a pressure block. This method will block a large area of ​​the connecting rod, which is prone to collision during the grinding process. Not only will the connecting rod be easily damaged, but the collision will also cause damage to the device, resulting in economic losses. Therefore, we proposed a clamping device for grinding connecting rod parts. Utility Model Content

[0004] The purpose of the utility model is to provide a clamping device for grinding connecting rod parts. By setting a clamping assembly, specifically two moving seats close to each other, the roller is clamped and fixed when it contacts the connecting rod.
