8. The use method of the clamping device for processing the brake drum of the car as claimed in claims 1-7, is characterized in that the use method of the clamping device comprises the following steps:
step 1: when the clamping device is used, the first handle (202) is rotated to drive the third threaded shaft (203) to rotate, the third threaded shaft (203) rotates to drive the sliding plate (204) to slide, the sliding plate (204) slides to drive the first hole (205) to move, the first hole (205), the sucker (206) and the second hole (207) are staggered, an air inlet channel of the sucker (206) is closed, the fixing plate (101) is pressed on a workbench, and the clamping device can be firmly adsorbed and fixed on the workbench under the action of the sucker (206);
step 2: when the brake drum is clamped, a pressure value is set on a pressure sensor (305) through a controller (107), the value is the value of the brake drum which is clamped, then the controller (107) controls a motor (102) to rotate, the motor (102) drives a first threaded shaft (103) to rotate, the first threaded shaft (103) drives a second threaded shaft (105) to rotate through a connecting shaft (104), the first threaded shaft (103) and the second threaded shaft (105) respectively drive a first sliding block (106) to slide, the first sliding block (106) drives a first connecting block (302) to slide through a connecting plate (301), the first connecting block (302) drives a clamping block (402) to move through a second connecting block (401), the clamping block (402) stops moving when contacting the brake drum, the connecting plate (301) drives a second sliding block (304) to slide through a first spring (303), and the second sliding block (304) can extrude the pressure sensor (305), when the value set on the pressure sensor (305) is reached, the pressure sensor (305) controls the alarm (108) to give an alarm through the controller (107), a worker turns off the motor (102) through the controller (107), and the brake drum is clamped;
and step 3: when the clamping block (402) needs to be replaced, the pull rod (404) is pulled to drive the third sliding block (405) to move, the third sliding block (405) drives the positioning block (406) to leave the clamping block (402), when the positioning block (406) is not in contact with the clamping block (402), the clamping block (402) can be taken down, then the clamping block (402) to be used is aligned with the groove on the second connecting block (401), the clamping block (402) is pushed, the clamping block (402) can extrude the positioning block (406) to drive the positioning block (406) to slide when sliding, the positioning block (406) compresses the second spring (407) through the third sliding block (405), when the positioning block (406) is in contact with the sliding groove (403) on the clamping block (402), the pressure on the second spring (407) disappears, the second spring (407) drives the positioning block (406) to reset through the third sliding block (405) to limit and fix the clamping block (402), and the clamping block (402) is installed well, completing the replacement of the clamping block (402);
and 4, step 4: when clamp splice (402) need be changed, drive fourth threaded shaft (409) through rotating second handle (408) and rotate, fourth threaded shaft (409) rotate and drive push pedal (411) and leave clamp splice (402), when push pedal (411) and clamp splice (402) contactless, can take off clamp splice (402), then insert inside the recess on second connecting block (401) clamp splice (402) that need use, drive spout (403) that push pedal (411) inserted in clamp splice (402) through reverse rotation second handle (408), carry out spacing fixed to clamp splice (402), install clamp splice (402), the completion is to the change of clamp splice (402).
