The coarse and fine grinding plates will wear out during use and need to be replaced regularly. However, the coarse and fine grinding plates can only be replaced as a whole, which increases the cost of use. Utility Model Content

[0005] The purpose of this utility model is to provide a brake pad steel back grinding machine that is easy to fix, which can grind the brake pad steel back and replace the grinding structure separately when replacement is needed, thereby reducing the cost of use.

[0006] To achieve the above objectives, a brake pad steel backing grinding machine that facilitates fixation is provided. The machine includes a worktable with two L-shaped support frames fixedly connected to its upper end. These support frames are symmetrically arranged on both sides of the worktable. Each support frame contains a fixing mechanism that passes through and slidably connects to the support frame. Sandpaper is placed on the upper surface of the worktable and fixed to it by the fixing mechanisms. A grinding mechanism is fixedly connected to the upper end of the worktable. An L-shaped fixing plate is fixedly connected to the end of the grinding mechanism away from the sandpaper, and the lower end of the fixing plate is fixedly connected to the worktable. A clamping mechanism is installed on the side of the grinding mechanism facing the sandpaper, with its end extending directly above the sandpaper. A motor is fixedly connected to the upper end of the worktable, and the motor's output is connected to the grinding mechanism. This machine can grind the steel backing of brake pads, and when replacement is needed, the grinding structure can be replaced separately, reducing operating costs.

[0007] According to the aforementioned brake pad steel backing grinder for easy fixing, the fixing mechanism consists of a handle, a sliding rod, and a pressure plate. The handle is located above a support frame. The sliding rod is fixedly connected to the lower middle part of the handle and extends downward through the support frame, slidingly connected to it. The pressure plate is fixedly connected to the lower end of the sliding rod and applies pressure to the sandpaper. Lifting the handle upwards causes the pressure plate to move away from the sandpaper, facilitating the removal of the sandpaper.

[0008] According to the aforementioned brake pad steel backing grinder for easy fixation, two tapered rods are symmetrically fixedly connected to the lower end of the pressure plate, and the tapered rods penetrate downwards through the sandpaper and the worktable. The surface of the worktable has openings to accommodate the tapered rods. The tapered rods are used to penetrate the sandpaper, further improving the fixation effect on the sandpaper.

One end of the slider is fixedly connected to the clamping mechanism. The rack is fixedly connected to the lower end of the slider, and the sector gear meshes with the rack. The fixing plate is fixedly connected to the second mounting bracket. The motor drives the adjusting roller to rotate, causing the adjusting block to move in the adjusting groove on the surface of the adjusting roller, thereby driving the sector gear to swing. The meshing of the sector gear and the rack causes the slider to drive the clamping mechanism to reciprocate.

[0011] According to the aforementioned brake pad steel backing grinder for easy fixation, the clamping mechanism comprises a first mounting frame, a connecting rod, a clamping block, a handwheel, a double-acting screw, and an adjusting block. The first mounting frame is fixedly connected to the slider. The double-acting screw is disposed in the first mounting frame, and both ends of the double-acting screw pass through the first mounting frame and are rotatably connected to it. A support block is fixedly connected to the middle of the first mounting frame, and the double-acting screw passes through the middle of the support block and is rotatably connected to it. Two threads on the surface of the double-acting screw are located on both sides of the support block. Two adjusting blocks are provided and symmetrically disposed on both sides of the support block, and the adjusting blocks are slidably connected to the inner wall of the first mounting frame. The double-acting screw passes through the middle of the adjusting block and is threadedly engaged with it.
