Problems solved by technology

However, due to the influence of many factors such as the material uniformity of the manufacturing roller, the accuracy of calculation, and the installation method, there is an error between the compensation curve obtained in the final processing and the actual deflection curve, which needs to be measured, error corrected, and reprocessed. Meet the requirements, so the amount of calculation is large, the process is complicated, the processing cycle is long, and the manufacturing cost is high

Embodiment Construction

[0023] The method for processing the slender roller for friction proposed by the present invention is described as follows in conjunction with the accompanying drawings and examples.

[0024] Realize the special-purpose precision machine tool of processing method of the present invention and comprise precision lathe head box, special-purpose lathe slide plate, precision lathe bed, precision lathe top; The rollers are clamped on the top ends similar to the friction and polishing machines, and the rollers are driven to rotate by the end face of the lathe spindle, and the turning tool cuts under the rollers to directly cut off the deflection of the rollers due to their own weight. Realize the direct compensation of the deflection deformation of the slender (such as φ100~φ200×1000~3000mm friction roller) roller.

[0025] like Figure 4 , Figure 5 As shown, the special precision machine tool used in the present embodiment includes a precision lathe head box 1, a tool rest 2, a l...

Abstract

The invention relates to the technical field of machining, and provides a method for machining a slender friction roller. The method comprises the steps of: placing a roller to be machined above a turning tool holder of a lathe and clamping the roller at the center of both ends; driving the roller to be machined to rotate; and controlling the turning tool to cut the roller to be machined transversely and longitudinally until the roller meets the required size. In the method, the downward deflection and deformation of the friction roller generated by the own weight thereof can be compensated only using one special precision lathe, thereby saving the manufacturing cost as well as completing the compensation machining accurately once.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for compensating the deflection and deformation of a friction roller due to its own weight. Background technique [0002] In the rubbing orientation processing of the LCD production process and the polishing and deburring process of the thin film solar cell production process, it is necessary to use a slender friction polishing roller with a rubbing cloth attached to the surface. Due to its relatively large slenderness ratio, the roller will deflect downward due to its own weight, such as figure 1 As shown, the indentation of the middle part and both ends of the roller during friction and polishing is uneven, which will directly affect the quality of friction and polishing. [0003] In order to overcome the uneven pressing amount caused by the deflection of the roller's own weight, at present, when manufacturing the roller, it is usually based on the calcu...
