Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake pad processing, in particular to an automobile brake pad grinding device. Background Art

[0002] Automobile brake pads, also known as automobile brake leathers, refer to the friction material fixed to the brake drum or brake disc that rotates with the wheel. The friction lining and friction pads withstand external pressure, generating friction to achieve the purpose of vehicle deceleration. Automobile brake pads are generally composed of steel plates, adhesive insulation layers and friction pads. The steel plates must be painted to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution of the painting process to ensure quality. Grinding is a grinding and polishing process in the machinery manufacturing, processing, mold, wood and leather industries. Its purpose is to remove burrs or irregular edges and corners on the surface of the product workpiece to make it smooth and easy to continue processing or reach the finished product. This requires a grinding device for automobile brake pad production.

[0003] Currently, most of the general automobile brake pad production grinding devices on the market are inconvenient to grind brake pads of different thicknesses, and are prone to causing waste chips to fly during grinding, causing environmental pollution and affecting the health of workers. Therefore, there is room for improvement. Utility Model Content

[0004] The utility model provides a vehicle brake pad grinding device to solve the problems raised in the background technology.

[0005] In order to solve the above problems, the present invention provides a vehicle brake pad grinding device, including a dust box, a lower grinding box, and an upper grinding box. The top plate of the dust box is connected to a circular dust cover, and the dust cover is fixed to the bottom of the lower grinding box. The lower grinding box is circular, and a plurality of dust removal holes connected to the dust cover are equidistantly arranged around the axis in the middle of the lower grinding box. The lower grinding box is installed on the top of the dust box through a plurality of support columns, and a plurality of clamping boxes are equidistantly arranged around the dust removal holes in the lower grinding box. The outer surface of the lower grinding box is fixed with a ring. The positioning ring of the lower polishing box is wrapped around the upper polishing box, and the upper polishing box is buckled on the top of the lower polishing box, and the lower surface of the upper polishing box matches the positioning ring. A polishing disc is rotatably provided in the upper polishing box, and the polishing disc is movably embedded in the lower polishing box. A driving motor for driving the polishing disc to rotate is provided on the top of the upper polishing box. A support frame is fixedly installed on the top of the upper polishing box, and a telescopic rod is fixedly installed on the top of the support frame, and the top of the telescopic rod is installed on a U-shaped mounting top on one side, and the lower end of the mounting frame is fixedly connected to the rear side of the dust removal box.

[0006] Preferably: an arc-shaped clamping block is fixedly provided on one side of the clamping box, and an arc-shaped clamping plate is movably provided on the side of the clamping box corresponding to the clamping block. An adjusting threaded rod is rotatably provided on the top of the outer surface of the clamping plate, and the other end of the adjusting threaded rod is rotatably passed through the outside of the clamping box. A guide rod is respectively provided on both sides of the adjusting threaded rod on the outside of the clamping box, and the guide rod slides through the clamping box.

[0007] Preferably, two threaded positioning rods are symmetrically provided in the positioning ring, and a positioning plate is provided on the top of the positioning rod to abut against the bottom edge of the upper polishing box.

[0008] Preferably, a sealing door for opening and closing the dust collection box is provided on one side of the bottom of the dust collection box.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] 1. Use the clamping box in the lower grinding box to prevent the brake pad that needs to be ground. Use the clamping block and the adjusting threaded rod to drive the clamping plate to fix the clamping piece. Then the telescopic rod drives the upper grinding box to move down and engage with the lower grinding box, so that the grinding disc contacts the upper surface of the brake pad. Then the driving motor drives the grinding disc to rotate to grind the surface of the brake pad. Since the upper grinding box is engaged with the lower grinding box, the waste chips generated during grinding are not easy to fly away and pollute the environment, and are not easy to affect the health of the staff.

[0011] 2. The suction force is passed into the dust cover through the dust box, and the waste chips generated in the lower sanding box are sucked in through the dust removal hole and then collected. This can prevent the waste chips from remaining in the lower sanding box and affecting the sanding effect, thereby improving the sanding efficiency.

[0012] 3. By setting the two threaded positioning rods in the positioning ring, the height of the positioning rods can be adjusted, thereby adjusting the distance between the grinding disc and the brake pad placed in the clamping box in the lower grinding disc, thereby facilitating the grinding of brake pads of different thicknesses and improving work convenience.
