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.
