[0002] The camshaft is one of the main parts of the engine, used to control the engine's intake and exhaust. Its profile accuracy and surface roughness have a critical impact on engine performance. The machining accuracy and efficiency of the camshaft directly affect the manufacturer's product quality and market competitiveness.

[0003] In the patent for a cylindrical grinder with a grinding wheel dresser, which is published in China with publication number CN208629063U, the grinding wheel dresser is lowered to the corresponding position of the grinding wheel, and the grinding wheel can be dressed without stopping the machine to remove and install the grinding wheel, which saves manpower, improves work efficiency, and is conducive to automated operation. The limit wheel design on the spindle box not only plays a sliding role, but also plays a limiting and fixed role, making the dressing wheel more stable.

[0004] However, this device still has some shortcomings. Although the grinding wheel can be corrected by the diamond wheel in this way, the diamond wheel is installed directly above the grinding wheel. When processing special-shaped parts, it is easy to interfere with the grinding wheel. At the same time, under the action of the diamond wheel and the grinding wheel, only the electric push rod provides directional support, which can easily reduce the service life of the electric push rod. In response to the above problems, the inventors proposed a camshaft forming grinder grinding wheel correction mechanism to solve the above problems. Utility Model Content

[0007] Preferably, a mounting seat is fixedly connected to the top of the table body and near the center of the other side, the side end of the mounting seat is rotatably connected to the grinding wheel body, and the diamond wheel is located above the grinding wheel body, and the side end of the base plate away from the mounting seat is fixedly connected to the motor, and the output end of the motor passes through the base plate and is fixedly connected to the diamond wheel.

[0008] Preferably, an electric cylinder is fixedly connected to the top of the support plate near the center, the output end of the electric cylinder passes through the support plate and is fixedly connected to the long plate, the top of the L-shaped column is fixedly connected to a support block, and the bottom of the support block is fixedly connected to a disc at the center above the ring plate.

[0009] Preferably, a rotating plate is rotatably connected to the center of the bottom end of the disc, and the top end of the coupling is fixedly connected to the rotating plate. The top end of the rotating plate is fixedly connected to a limiting wheel 1, and the top end of the limiting wheel 1 contacts the disc.

[0010] Preferably, a motor is fixedly connected to the top of the support block and close to one side, and the output end of the motor passes through the support block and is fixedly connected to the rotating plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the utility model, by running the motor, the rotating plate and the connecting shaft as well as the support plate, the long plate and the bottom plate cooperate with each other, thereby avoiding the phenomenon of the diamond wheel interfering with the grinding wheel body, thereby solving the problem that the diamond wheel is installed just above the grinding wheel and is easy to interfere with the grinding wheel when processing special-shaped parts;

[0013] 2.
