Grinding device for machining for insulation bushings and loops of solar cell array substrate

Abstract

The invention discloses a grinding device for machining for insulation bushings and loops of a solar cell array substrate. The grinding device comprises a grinding head, a circular shaft, an adjustment gasket, a handle, an upper cover plate, a lower cover plate and an adjustment nut, wherein the upper cover plate and the lower cover plate are assembled through a location pin and a connection bolt;the grinding head is a diamond grinding head, and installed at the lower end of the circular shaft through a screw; the upper end of the circular shaft sequentially penetrates through a pin hole of the upper cover plate and the adjustment gasket, and then is connected with the handle; the upper surface and the lower surface of the adjustment gasket form mechanical contact with the handle and theupper cover plate separately; the adjustment nut is connected to the lower cover plate through a thread; and adjustment the height of the device in a product can be realized through rotating the adjustment nut, so as to control the machining thickness of the product. The grinding device disclosed by the invention is capable of rapidly and effectively realizing grinding for the planeness of the insulation bushings and the loops at a hinged support seat of the solar cell array substrate; the planeness of a plane composed of the bushings at the same side of the hinged support seat can be within 0.02mm; the planeness of a single bushing of the hinged support seat can be within 0.01mm; and machining and production can be rapidly and effectively completed.

Description

technical field

[0001] The invention relates to the technical field of processing solar cell array substrates, in particular to a grinding device for processing insulating bushes and ring sleeves of solar cell array substrates. Background technique

[0002] The solar cell array substrate is composed of carbon / epoxy panels, carbon / epoxy thin-walled frames, honeycomb cores, hinge supports, compression sleeves, insulating bushings and various embedded parts, etc., and is formed by bonding Craftsmanship compounded into a monolithic structure. Generally, there are four carbon fiber hinge supports at the four corners of the solar cell array substrate, and there are two sets of insulating bushing rings on each hinge support.

[0003] At present, the processing methods of solar cell array substrates mainly include mechanical processing and manual grinding. The machining method is to clamp the substrate on the worktable of the gantry milling machine, and mill the hinge support bush...
