In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A thread grinding machine, comprising:

[0006] A machine tool base, wherein the machine tool base is provided with a grinding wheel frame;

[0007] The drum is sleeved in the grinding wheel frame in a rotating structure;

[0008] A mounting plate, the mounting plate is arranged on one side of the drum in a fixed structure manner;

[0009] A driver, which is arranged on the outer side of the mounting plate in a fixed structure;

[0010] A grinding wheel, which is arranged on the left side of the driver and connected to the driver;

[0011] Grinding wheel dresser: The grinding wheel dresser is arranged on the mounting plate on the left side of the grinding wheel.

[0012] Furthermore, a worm wheel is arranged on one side of the drum away from the mounting plate in a fixed structure, the worm wheel is arranged with a worm through threaded engagement, and the worm is connected to the machine tool base in a rotating structure.

[0013] Furthermore, the grinding wheel frame consists of an upper shell and a lower shell, and the upper shell and the lower shell are connected by bolts.

[0014] Furthermore, the driver is an electric spindle or a servo motor.

[0015] Furthermore, a cross slide is arranged on the outer side of the mounting plate in a fixed structure manner, and the cross slide is fixedly connected to the grinding wheel dresser.

[0016] The beneficial effects of the utility model are:

[0017] The grinding wheel dresser and grinding wheel are installed on the end surface of the drum, which minimizes the error caused by the adjustment of the grinding wheel dresser and the grinding wheel due to the adjustment of the helix angle, thereby improving the overall grinding speed and accuracy of the machine tool.

[0018] The worm gear drives the drum to rotate to adjust the helix angle; the drum is installed in the middle of the split upper and lower shells in an overall cylindrical structure, and the drum is fixed with a unique structure; the grinding wheel dresser and driver are installed on the left and right sides of the grinding wheel respectively. This design can not only meet the function of adjusting the grinding wheel, but also improve the stability of the structure, making the grinding wheel more stable and efficient during the grinding process.
