[0002] A grinder is a common processing equipment in the mechanical processing industry. Its main function is to use abrasive tools to grind the surface of the workpiece, and it can also trim the surface of the workpiece, improve the surface quality of the workpiece and improve the dimensional accuracy of the workpiece. It can achieve high-precision, high-finish, high-efficiency and high-automation processing, and often grinds the tool to ensure the sharpness of the tool so that its accuracy can be improved during use.

[0003] During the use of the grinder, it is often necessary to manually load and unload the material. This process will waste a certain amount of time, thereby reducing the processing speed and affecting production efficiency. After clamping is completed, the angle of the workpiece needs to be adjusted manually. Improper operation during this process can easily damage the workpiece and cause harm to the staff. In order to solve the above problems, a high-precision CNC tool grinder with fully automatic loading and unloading mechanism is urgently needed to solve the above problems. Utility Model Content

[0017] 1. In the utility model, a pushing frame is provided inside. When loading and unloading is required, the motor is started, and the transmission shaft of the motor rotates to drive the first threaded rod to rotate. The rotation of the first threaded rod drives the pushing frame to move, thereby pushing the workpiece to move and ejecting the processed parts in the fixed sleeve into the collection box. Through this design, automatic loading and unloading of the workpiece is realized, thereby reducing the time required for loading and unloading during the processing, increasing the processing speed of the workpiece, and thus improving the processing efficiency.

[0028] The specific implementation method is as follows: when loading and unloading is required, the motor 45 is started, the transmission shaft of the motor 45 rotates to drive the first threaded rod 42 to rotate, the rotation of the first threaded rod 42 drives the push frame 41 to move, thereby pushing the workpiece to move and ejecting the processed parts in the fixed sleeve 31 into the collection box 9, and at the same time, the first bevel gear 43 drives the second bevel gear 44 to rotate, thereby driving the second threaded rod 47 to rotate, thereby driving the slider 46 to move, and the movement of the slider 46 lifts the sliding frame 6 to drive the workpiece at its top to move and slide it to the next position;

When the fixed table 38 generates resistance to the limit block 36, the pushing frame 41 pushes the workpiece completely into the fixed sleeve 31 and fixes it by pushing the clamping jaw 32 through the electric push rod 33. The toothed disc 35 continues to rotate, thereby driving the workpiece to rotate to a suitable angle through the mounting rod 37.
