[0020] The automobile clutch welding slag grinding device comprises a servo motor 2, a reducer 3, a floating milling cutter disc 6, a connector 4, a support sleeve 5, a milling cutter blade 15, a cutter seat 12 and a clamping block 13 (see the attached manual). Figure 1 and 3 ).

[0021] The servo motor 2 is equipped with a support sleeve 5 through a reducer 3 and a connector 4 (see the appendix of the manual). Figure 1 and 3). When the servo motor 2 is working, it drives the support sleeve 5 to rotate with the cooperation of the reducer 3 and the connector 4.

[0022] The upper end of the support sleeve 5 is provided with a floating milling cutter disc 6 (see the attached manual). Figure 1 , 2 and 3). A plurality of positioning screws 7 are installed on the floating cutter disc 6 through the countersunk holes; a reset spring 8 is sleeved on the positioning screw 7 below the floating cutter disc 6; and the reset spring 8 is in contact with the support sleeve 5 and the floating cutter disc 6.

[0023] A plurality of guide openings 9 are arranged on the circumferential surface of the floating milling cutter disc 6; a guide pin 10 is fixedly mounted on the support sleeve 5 below the guide opening 9; the upper end of the guide pin 10 extends to the inside of the guide opening 9 and is slidably connected thereto (see instructions 1 and 2). The purpose of setting the guide pin 10 and the reset spring 8 is to enable the floating milling cutter disc 6 to drive the milling blade 15 to rotate to complete the welding slag grinding process. When the floating milling cutter disc 6 is subjected to force, it can overcome the elastic force of the reset spring 8 and move up and down under the guidance of the guide pin 10, so that the grinding device can brake and avoid according to the grinding situation when working, thereby reducing the risk of "chipping" of the milling blade 15.

[0024] A tool holder 12 is mounted on the floating milling cutter disc 6 on one side of the guide opening 9 via a fastening screw 11; a milling cutter blade 15 is fixedly mounted on the tool holder 12 via a clamping block 13 and a pressing screw 14 (see the attached manual). Figure 2 During operation, the milling cutter 15 can be replaced by the clamping block 13 and the cutter seat 12 according to the different workpiece models.

[0025] The floating milling cutter disc 6 is provided with an avoidance through hole 16 in the middle (see the attached manual). Figure 2 The support sleeve 5 is a stepped hollow shaft structure; a plurality of weight-reducing holes 17 are arranged on the circumferential surface of the upper end of the support sleeve 5 (see the attached Figure 1 During operation, the automobile clutch shaft 1 can be inserted into the interior of the support sleeve 5 through the through hole 16 .

[0026] The connector 4 includes a bearing seat 18, a pressure plate 19 and a locking screw 20; the bearing seat 18 is fixedly mounted on the upper end of the reducer 3 housing; the lower end of the support sleeve 5 is inserted into the interior of the bearing seat 18 and connected to the inner ring of the bearing of the bearing seat 18.

[0027] A pressure plate 19 is placed inside the upper end of the support sleeve 5; the locking screw 20 passes through the pressure plate 19 and is connected to the output shaft of the reducer 3. A dust plate 21 is installed on the end surface of the step surface of the support sleeve 5 by screws (see the attached manual). Figure 1 and 7 ).

[0028] The purpose of setting the connector 4 in this way is to enable the servo motor 2 to drive the reducer 3 to rotate, and the reducer 3 can drive the support sleeve 5 to rotate through the output shaft, the locking screw 20 and the pressure plate 19. The bearing seat 18 and the dust plate 21 of the connector 4 can isolate the inside and outside of the bearing seat 18, thereby preventing foreign matter from entering the inside of the bearing seat 18 and causing bearing damage.

[0029] The automobile clutch welding slag grinding device has a compact structure and ingenious design. When working, the automobile clutch shaft 1 can pass through the floating milling cutter disc 6 and then be inserted into the interior of the support sleeve 5, so that the rotating floating milling cutter disc 6 can complete the welding slag grinding work through the milling blade 15, thereby solving the problems of high work intensity and low efficiency in the existing automobile clutch grinding method, and is particularly suitable for the needs of automobile clutch welding slag grinding.
