[0001] The utility model relates to the technical field of casting grinding, in particular to a fully automatic grinding and shear edge processing device for automobile castings. Background Art

[0002] Polishing automotive castings is a critical step in the automotive manufacturing process, designed to improve the surface finish and precision of the castings. This process typically involves using tools such as sandpaper, grinders, or sandblasting equipment to remove burrs, flash, and scale from the casting surface, ensuring that the size and shape meet design requirements. Polishing not only improves the casting's appearance but also enhances its corrosion resistance and fatigue strength, extending its service life.

[0003] According to the Chinese patent announcement number: CN221020389U, a grinding device for automobile casting processing includes a box body, a connecting mechanism and several grinding tool assemblies. The two inner side walls of the box body are fixedly installed with a telescopic rod 1, the connecting mechanism is fixedly connected to the telescopic end of the telescopic rod 1, and a clamp is fixedly installed on the end of the connecting mechanism away from the telescopic rod 1; the inner top wall of the box body is provided with a groove 1, and a screw rod is rotatably connected in the groove 1. The several grinding tool assemblies are transmission-connected to the outside of the screw rod.

[0004] In the above scheme, the casting is polished by a mold assembly, which still has the following disadvantages: the angle between the mold assembly and the casting is fixed, and there may be a certain angle on the casting surface and the mold assembly cannot change the angle for coordinated polishing, which reduces the scope of application of casting polishing. Utility Model Content

[0005] The purpose of the utility model is to provide a fully automatic shear edge grinding processing device for automobile castings, so as to solve the problem that there may be a certain angle on the casting surface and the grinding tool assembly cannot change the angle for coordinated grinding, which reduces the scope of application of casting grinding.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: a fully automatic shear edge grinding processing device for automobile castings, comprising a workbench, the top surface of the workbench is provided with two sliding grooves, a sliding plate is slidably provided inside the sliding groove, a lifting plate is slidably provided above the sliding plate, a connecting groove is provided on the top surface of the lifting plate, a connecting folding plate is rotatably provided inside the connecting groove, threaded pipes are respectively fixed on both sides of the connecting folding plate, rotating holes are respectively provided on both sides of the connecting groove, the rotating holes and the threaded pipes are rotatably inserted, the internal thread of the threaded pipe is connected with an extrusion bolt, and a grinding plate is fixed on one side of the connecting folding plate.

[0007] Preferably, a sliding rod is fixed inside the sliding groove, and a compression spring is surrounded by the surface of the sliding rod. One end of the compression spring is fixed to one side of the sliding plate, and the other end of the compression spring is fixed to one side inside the sliding groove.

[0008] Preferably, a threaded column is fixed on the top surface of the sliding plate, a mounting groove is opened on the bottom surface of the lifting plate, a mounting plate is fixed inside the mounting groove, the mounting plate and the threaded column are slidably inserted, and two nuts are threadedly connected to the threaded column, and the two nuts are respectively located above and below the mounting plate.

[0009] Preferably, two stabilizing rods are fixed to the top surface of the sliding plate, and the stabilizing rods are slidably inserted into the lifting plate.

[0010] Preferably, a fixing groove is provided on the top surface of the workbench, a motor is fixed on the inner bottom surface of the fixing groove, and a turntable is fixed on the top end of the motor output shaft.

[0011] Preferably, a supporting folding plate is fixed to the top surface of the workbench, a fixing hole is opened on the top surface of the supporting folding plate, a bearing is fixed inside the fixing hole, a rotating ring is rotatably arranged inside the fixing hole, the surface of the rotating ring is fixed to the inner wall surface of the inner ring of the bearing, a pressing rod is slidably inserted into the interior of the rotating ring, an elastic pad is fixed to the bottom end of the pressing rod, a pressing spring is surrounded by the surface of the pressing rod, one end of the pressing spring is fixed to the top surface of the elastic pad, and the other end of the pressing spring is fixed to the inner top surface of the supporting folding plate.

[0012] Compared with the existing technology, the fully automatic shear edge grinding device for automobile castings using the above technical solution has the following beneficial effects:

[0013] 1. The staff will first apply a force to the two connecting folding plates to move away from each other, so that the distance between the two connecting folding plates can be increased. Then the staff will place the casting inside the workbench, so that the spacing between the two connecting folding plates can be equal to the length of the casting. Then the staff can adjust the angle between the lifting plate and the connecting folding plate according to the angle of the casting surface. Before adjustment, the staff will first unscrew the extrusion bolt from the inside of the threaded tube, and then the staff can apply a rotational force to the connecting folding plate to adjust the angle between the lifting plate and the connecting folding plate. After the angle of the connecting folding plate is adjusted, the staff will screw the extrusion bolt into the inside of the threaded tube again, so that the head of the extrusion bolt can be squeezed on one side of the lifting plate, thereby increasing the firmness of the connecting folding plate after the angle is adjusted. By adjusting the angle of the connecting folding plate, the grinding plate can be driven to fit the surface of the casting, thereby increasing the applicable range of the grinding plate when grinding the casting.

[0014] Second, automated equipment is used to replace manual polishing. The original manual polishing of 400-500 pieces per person per shift has been increased to 1200-1300 pieces per person per shift. The residual protrusion or concave of the casting riser after polishing is less than or equal to 1.0mm, and the residual height of the parting line is less than or equal to 0.5mm. When adjusting the height of the lifting plate, the staff will first rotate the upper nut so that the upper nut will move upward on the threaded column. Then the staff will apply an upward force to the lifting plate and then move the lower nut upward on the threaded column. Then, the lifting plate can be fixed at a specific height, and different heights of the casting surface can be polished, which increases the polishable coverage area.

[0015] 3. The casting is on the top surface of the turntable on the workbench, and the elastic pad will press on the top surface of the casting. At this time, the pressure spring is in a compressed state, so the compressed pressure spring will exert a downward force on the elastic pad, which can exert a downward pressing force on the casting, thereby increasing the firmness of the casting during grinding.
