Self-adaptive surface structure fine grinding device

Abstract

The self-adaptive surface structure fine grinding device mainly comprises a grinding box body, supporting legs, a collecting box, a discharging opening, a discharging valve, a feeding window, an overhauling window and a grinding platform, the grinding box body is installed at the upper ends of the supporting legs, the feeding window and the overhauling window are arranged on the side face of the grinding box body, and the lower end of the grinding box body is connected with the upper surface of the grinding platform; the lower surface of the polishing platform is connected with a collecting box, a discharging port is formed in the collecting box, and a discharging valve is arranged on the discharging port. According to the product, the grinding box, the rubber layer, the hoop, the grinding belt and the like are adopted to form an isostatic pressing mechanism, a certain amount of hydraulic oil is injected into the grinding box, needed grinding pressure is kept, and the rubber layer and the grinding belt can better adapt to conventional non-planar grinding structures with uncomplicated surface structures, especially grinding structures of long profiles and the like.

Description

technical field [0001] The invention relates to the technical field of surface grinding and polishing, in particular to an adaptive surface structure fine grinding device. Background technique [0002] At present, a considerable part of grinding in the grinding industry is done manually by skilled workers, with a low level of automation. Manual grinding is not only labor-intensive, time-consuming, and inefficient, but also the dust generated by grinding is harmful to the health of workers. Grinding with rotating friction plates is only suitable for structures with flat surfaces; the grinding and polishing of some curved surface parts, especially long profiles, is basically done by manual hand-held operations, which is difficult to guarantee the shape and position accuracy of free-form surface parts , Surface microscopic physical properties. The versatility of special-purpose machine tools is poor, suitable for mass production, and the scalability is not strong. Not only th...

Problems solved by technology

Manual grinding is not only labor-intensive, time-consuming, and inefficient, but also the dust generated by grinding is harmful to the health of workers

Grinding with rotating friction plates is only suitable for structures with flat surfaces; the grinding and polishing of some curved surface parts, especially long profiles, is basically done by manual hand-held operations, which is difficult to guarantee the shape and position accuracy of free-form surface parts , surface microscopic physical properties

The versatility of special-purpose machine tools is poor, suitable for mass production, and the scalability is not strong. Not only that, special-purpose machine tools are expensive

[0003] At present, the adaptive grinding technology of the existing technology mainly adopts multiple sets of adaptive rods with "differential" structures. Such a design structure is relatively complicated, and the actual grinding error is relatively large, and the surface grinding effect is relatively poor. Related designs can be found in China. Patent 202010993911.4

In addition, there is a constant force automatic grinding method based on fuzzy adaptive force control. This algorithm is relatively complicated, and it is not conducive to large-scale promotion and use for the grinding requirements of various specifications and shapes in actual production. The related design See Chinese patent 201510161357.2

[0004] Therefore, the traditional position control method can no longer meet the higher and higher requirements for product surface quality. Adding "isostatic grinding" to the automatic grinding equipment is an effective way to solve this problem
