Polisher spindle device and roll changing method

Abstract

The invention relates to a polisher spindle device and a roll changing method. A second driving mechanism drives whole support mechanisms and a spindle body on the support mechanisms to move on a guide rail along the axial direction of the spindle body, and sliding blocks connected to the bottoms of the support mechanisms move on the guide rail, so that the spindle body and a polishing roll on thespindle body are vibrated in a reciprocating mode, and the problem that chromatic aberration, attractiveness and the like appearing on the surface of a polished aluminum alloy plate are difficult tomeet customer requirements is solved; a supporting and limiting structure is located between each two adjacent support mechanisms, a locking part is disassembled firstly, then the support mechanism onone side is disassembled, finally, the polishing roll is taken out while the supporting and limiting structure is disassembled, a new polishing roll is changed, then the supporting and limiting structure is installed, and the support mechanism and the locking part on one side are installed, so that rapid changing of the polishing roll is achieved; and the spindle device with the structure achieves the characteristics of high-frequency reciprocating oscillation and rapid roll changing of the spindle device.

Description

technical field [0001] The invention relates to the technical field of polishing machine spindles, in particular to a polishing machine spindle device and a roll changing method. Background technique [0002] The plate polishing machine is mainly used to remove the irregular oxide layer on the surface of the aluminum plate and eliminate micro-cracks, while improving the aesthetics of the aluminum plate surface. It is mainly composed of a frame, a spindle unit, a lifting device, a pinch roller device, a brush roller grinding device, etc., and the spindle device is the core component of the polishing machine. [0003] The main shaft device of the polishing machine determines the polishing quality of the plate and the operation stability of the polishing production line. Therefore, in order to ensure the consistency of the surface texture of the aluminum alloy plate during the polishing production process, the main shaft unit usually needs to have the function of reciprocating ...

AI Technical Summary

Problems solved by technology

In addition, during the polishing production process, the brush grinding roller needs to be replaced frequently due to consumption and product replacement, so the polishing machine must have the convenient function of changing rollers

[0004] However, the traditional existing polishing machine does not have the function of reciprocating oscillation, which often leads to color difference on the surface of the aluminum alloy sheet after polishing, and at the same time, the surface of the aluminum alloy sheet on both sides of the roller will also have corresponding indentations at both ends, making it difficult to meet the aesthetics. customer demand

In addition, it is difficult to replace the existing non-woven brush rollers. It takes a long time to change a roller, usually 4 to 6 hours, which affects production efficiency.
