[0002] Forgings refer to parts that are made of metal materials into the desired shape through forging processes. Forgings usually have high strength, toughness and wear resistance, and are widely used in various industries such as automobile manufacturing, aerospace, energy, etc.

[0003] During forging processing, the outer surface needs to be polished, but not all forging surfaces are flat. When processing forgings with curved surfaces, it is necessary to pre-scan the forging style and perform programming adjustments. The entire processing process is very cumbersome and inconvenient, affecting the polishing quality and efficiency. Utility Model Content

[0004] The utility model aims to solve the above problems and proposes a grinding device for forgings with adjustable impact resistance.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] A grinding device for processing impact-resistant adjustable forgings comprises a base, the upper end of the base is fixedly connected to a U-shaped vertical plate, the upper end of the U-shaped vertical plate is fixedly connected to an electric push rod via a mobile drive mechanism, the lower output end of the electric push rod is fixedly provided with a concave-convex change feedback mechanism, the lower end of the concave-convex change feedback mechanism is fixedly connected to a grinding motor via a universal connecting seat, the lower output end of the grinding motor is fixedly connected to a grinding wheel, the lower end of the concave-convex change feedback mechanism and the upper end of the grinding motor are fixedly connected to a plurality of circumferentially arranged compensation springs, and a PLC controller is also fixedly provided on the outer wall of the U-shaped vertical plate.

[0007] Preferably, the mobile drive mechanism includes two side plates symmetrically fixedly connected to the upper end of the U-shaped vertical plate, and an adjusting screw is rotatably connected between the two side plates through a bearing, and a driving motor is fixedly connected to the side wall of one of the side plates, and the output end of the driving motor is fixedly connected to one end of the adjusting screw, and a moving block is threadedly sleeved on the rod wall of the adjusting screw, and the electric push rod is fixedly inserted into the moving block.

[0008] Preferably, the upper end of the U-shaped vertical plate is provided with a strip opening for the moving block to extend through, the inner wall of the U-shaped vertical plate corresponding to the strip opening is fixedly connected with a guide slide rod, and the side wall of the moving block is provided with a guide slide hole slidably connected to the guide slide rod.

[0009] Preferably, the concave-convex change feedback mechanism includes a support plate fixedly connected to the output end of the lower end of the electric push rod, the lower end of the support plate is fixedly connected to a mounting plate via a plurality of elastic telescopic rods, a trigger rod is fixedly connected to the middle position of the lower end of the support plate, a trigger tube sleeved outside the trigger rod is fixedly connected to the middle position of the upper end of the mounting plate, a forward trigger switch and a reverse trigger switch are symmetrically fixedly connected to the inner wall of the trigger tube, and a pressing convex head is fixedly connected to the lower end of the trigger rod.

[0010] Preferably, the output ends of the forward trigger switch and the reverse trigger switch are both electrically connected to the input end of the PLC controller, and the output end of the PLC controller is electrically connected to the input end of the electric push rod.

[0011] Preferably, rubber pads are fixedly connected to the four corners of the bottom of the base.

[0012] Compared with the prior art, the present application provides a grinding device for processing forgings with adjustable impact resistance, which has the following beneficial effects:

[0013] The grinding device for processing forgings with adjustable impact resistance places and fixes the forging to be ground on the base through a base and a U-shaped vertical plate. At the beginning, the pressing convex head acts on the positive trigger switch on the upper side, and the positive trigger switch feeds back a signal to the PLC controller. The PLC controller starts the downward movement of the electric push rod, so that the grinding wheel contacts the forging. As the electric push rod continues to move downward, the support plate drives the trigger rod to move in the trigger cylinder. When the pressing convex head leaves the positive trigger switch, the PLC controller controls the electric push rod to stop moving, and the grinding motor drives the grinding wheel to move, so as to quickly grind the forging. The driving motor drives the adjusting screw to rotate. The threaded connection between the screw and the moving block enables the moving block to drive the grinding wheel to move horizontally, so as to adjust the grinding position of the forging in real time. When encountering a protrusion on the forging, the mounting plate moves relative to the support plate, so that the pressing convex head acts on the reverse trigger switch, thereby causing the electric push rod to move up and reduce the displacement. Similarly, when the pressing convex head leaves the reverse trigger switch, the PLC controller stops the movement of the electric push rod. When encountering a depression on the surface of the forging, the trigger rod at the lower end of the trigger tube moves downward, and the pressing convex head acts on the forward trigger switch, causing the electric push rod to move downward to compensate. The grinding position can be adjusted accordingly according to the degree of concavity on the forging surface to ensure the grinding quality and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The operating principle of the utility model is now described as follows:

[0025] When the present application is used, the forging to be polished is placed on the base 1 and fixed by means of the provided base 1 and the U-shaped vertical plate 2. At the beginning, the pressing convex head 22 acts on the positive trigger switch 20 on the upper side, and the positive trigger switch 20 feeds back a signal to the PLC controller 8.

The grinding position can be adjusted accordingly according to the degree of concavity on the surface of the forging to ensure the grinding quality and efficiency.
