Background
The light guide plate is a plate-shaped workpiece with a thickness of about 6mm and a complex outer contour shape, and is a thin plate mounted on an instrument panel in an aircraft cabin. After the light source in the light guide plate is electrified, various characters and figures on the light guide plate can emit light, and when the cabin is low in brightness, various switches, buttons, knobs and instruments can be indicated.
At present, more than one hundred types of light guide plates are repaired, and the types are continuously increased. In maintenance, a key step is to remove the paint layer on the surface of the light guide plate to expose the substrate of the bottom layer. However, due to material limitations, chemical paint removal or sand blasting cannot be used, and only physical grinding can be used. The physical grinding is to press the light guide plate workpiece on sand paper by hand for grinding. The maintenance quality is affected by the play, deformation and warpage of the abrasive paper and the uneven distribution of the pressing force of the workpiece, so the physical grinding mode has the problems of poor reliability, unsatisfactory processing effect, low efficiency, easy workpiece disqualification, worker injury and the like.
In addition, although there is a mature electric sanding tool in the market, no proper clamp is available for effectively fixing the light guide plate, so that the electric sanding tool cannot be used for grinding the light guide plate.
SUMMERY OF THE UTILITY MODEL
To adopting physics to grind the problem that mode and electronic sand light instrument detached light guide plate surface lacquer layer exists, the utility model provides an anchor clamps of side direction centre gripping light guide plate adopts this anchor clamps can realize the effective centre gripping to multiple size and shape light guide plate, and the peak of anchor clamps is not higher than the machined surface of light guide plate work piece moreover, can adopt electronic sand light instrument to grind this moment, can greatly improve and grind quality and improve work efficiency, and the operational safety is high moreover.
The purpose of the utility model is realized through the following technical scheme.
A clamp for laterally clamping a light guide plate comprises a base, a sliding block and a fixed block;
three or more crossed sliding grooves are processed on the upper surface of the base; the base plays a bearing role, the light guide plate, the sliding block and the fixed block are arranged on the base, and the base can be fixed on the workbench by the self weight of the base or fixed on equipment by screws and the like according to the actual operation condition;
the sliding block comprises a sliding block body and a stud, and the stud is vertically arranged on the upper surface of the sliding block body;
threaded holes are machined in the surfaces of the fixing blocks;
the slider body of slider and the spout sliding fit of base, a fixed block of installation on the double-screw bolt of each slider, the side of fixed block and the laminating of the clamping face of light guide plate realize the effective centre gripping to the light guide plate under the mating action of a plurality of sliders and fixed block, and the upper surface of fixed block and the double-screw bolt terminal surface of slider are all not higher than the thickness of light guide plate this moment.
Further, the upper surface of the base is processed with three crossed sliding grooves, and the three crossed sliding grooves are preferably spaced by 120 degrees.
Furthermore, an adjusting screw is further installed on the side face of the fixing block, and one end of the adjusting screw is in contact with the clamping face of the light guide plate by rotating the adjusting screw, so that effective clamping of the light guide plate is further ensured, and the clamping force is controllable. Preferably, two adjusting screws are mounted on the side surface of the fixing block.
Has the advantages that:
(1) Since the processing surfaces are the front surface and the back surface of the light guide plate, the clamping surface is the side surface of the light guide plate and is only about 6 mm. In order to ensure the processing quality, the highest point of the clamp cannot be higher than the processing surface. The utility model discloses under the mating reaction of slider and fixed block, realized the effective centre gripping to the narrower light guide plate of holding surface.
(2) The base is provided with a plurality of crossed sliding grooves, and under the matching action of the sliding blocks and the fixed blocks, the light guide plates in different sizes and shapes can be effectively clamped.
(3) The light guide plate is made of organic glass and has low strength. Too much clamping force may on the one hand damage the product and on the other hand deform the product. The utility model discloses mainly utilize the side of fixed block and the laminating of light guide plate clamping face to carry on spacingly, the clamp force that plays supplementary limiting displacement's adjusting screw moreover is controllable, can avoid the product to warp or damage.
(4) Anchor clamps simple structure, assembly, dismantlement and clean very convenient adopt the fixed light guide plate of this anchor clamps to remove lacquer moreover when, can improve processingquality, improve machining efficiency and reduce the injury to the worker.
