Description

Technical Field

[0001] The invention belongs to the technical field of workpiece grinding, and in particular relates to a grinding device for an automobile chassis bracket. Background Art

[0002] During the grinding process, a large amount of grinding heat is generated between the grinding disc and the material. Under such high temperature, the material will be deformed and burned, and the grinding wheel will also be severely worn, which will reduce the grinding quality.

When the floating plate 119 rises to contact with the contact switch 1111, it indicates that the grinding fluid has filled the bottom of the extraction port 112. The contact switch 1111 transmits a signal to the peripheral terminal, which receives the data and controls the secondary pump body 92 and the tertiary pump body 102 to open. The secondary pump body 92 guides the grinding agent at the bottom of the extraction port 112 to the top of the annular partition 95 through the extraction pipe 113, and guides it to the bottom of the annular partition 95 through the primary connecting pipe 93 and the secondary connecting pipe 94, and filters and blocks the grinding particles in the grinding agent through the annular filter 97.
