Description

Technical Field

[0001] The utility model relates to the technical field of polishing heads, in particular to a polishing head component with a detachable function. Background Art

[0002] The polishing head in the prior art polishing machine has the functions of lifting and rotating, and a jig plate is fixedly installed on the bottom of the polishing head. A plurality of vacuum suction holes are opened at the bottom of the jig plate. An air pipe is arranged on the polishing head, and the air pipe is connected with the plurality of vacuum suction holes. When the air pipe generates negative pressure, the plurality of vacuum suction holes can adsorb the product to be polished, and then the polishing head is driven to perform a lifting action, driving the product to rise or descend to the grinding disc until the part to be polished of the product contacts the rotating grinding disc, and then the polishing head is driven to drive the product to rotate, so as to realize the polishing process.

[0003] In the above, since the connection between the jig plate and the polishing head is a fixed installation setting, and the air pipe and the multiple vacuum suction holes are also fixedly connected, when the jig plate needs to be replaced after long-term use, the multiple fixed settings mentioned above must be removed first, and this removal work is relatively cumbersome and complicated. If the jig plate and the polishing head are connected through the quick-release structure in the prior art, then after the jig plate and the polishing head are connected, the staff also needs to connect the air pipe with the multiple vacuum suction holes. In summary, the assembly connection between the jig plate and the polishing head is divided into two steps. The first step is to quickly connect the jig plate and the polishing head using the quick-release structure, and the second step is to connect the air pipe with the multiple vacuum suction holes. The sequential implementation of these two steps is not only cumbersome to operate, but also prolongs the downtime of the polishing machine, delaying the production progress.

[0004] Therefore, we propose a polishing head assembly with a detachable function to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art and to propose a polishing head assembly with a detachable function.
