Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1 to 5, a novel grinding device for a main shaft of a machine tool comprises a base 1, a supporting seat 206 and a grinding head seat 210;
the supporting seat 206 is connected with the grinding head seat 210 and fixed on the base 1 after connection is finished; an angle auxiliary adjusting block 102 is arranged on the base 1;
the angle auxiliary adjusting block 102 is connected with the base 1; the angle adjusting block 203 is connected with a bearing baffle 204, a bearing 205 is arranged in the bearing baffle 204, and the bearing baffle 204 is connected with a supporting seat 206.
The device also comprises a handle 201, a slide rail 211, an adjusting block 212, a ball screw 208 and a motor mounting base 302;
the ball screw 208 penetrates through the bearing 205 and is arranged on the supporting seat 206, and the handle 201 is connected with the ball screw 208; the slide rail 211 is connected to the support base 206; the adjusting block 212 is mounted on the support base 206; the connecting seat is connected with the ball screw 208; the motor mount 302 is fixed on the slide rail 211.
The grinding head seat 210 further comprises a motor mounting plate 303, a grinding wheel connecting rod 304, a grinding wheel 305 and a direct current motor 301;
the direct current motor 301 is arranged in the motor mounting seat 302 and is fixed through the motor mounting plate 303; one end of the grinding wheel connecting rod 304 is connected with the grinding wheel 305, the other end of the grinding wheel connecting rod 304 is connected with an output shaft of the dc motor 301, and the motor mounting base 302 is arranged on the grinding head base 210.
During grinding, the device is fixed on a workbench of a machine tool, the mounting position of the device is adjusted according to the position needing grinding, and finally the base 1 is pressed tightly by a pressing plate.
