At this time, the rear side wall of the pedal piece 25 abuts against the right end of the pedal arm 21. Then, the third cylinder 72 is started to drive the right end of the connecting rod to rotate forward. Since the middle part of the connecting rod is hinged on the hinge block, the left end of the connecting rod rotates backward, thus driving the abutting claw 73 at the left end of the connecting rod to abut against the front side wall of the pedal piece 25, thus completing the positioning of the pedal piece 25;

[0067] In this embodiment, the booster connecting piece box 23, the pedal arm 21, the main shaft bushing 22, the brake light switch push rod limit contact piece 24 and the pedal piece 25 can be sequentially snapped into their corresponding positions, and then the first cylinder 42, the second cylinder 52 and the third cylinder 72 are simultaneously started to complete the limitation of the whole vehicle brake pedal body 2, and then welding fixation is carried out;

[0068] After welding is completed, the first cylinder 42, the second cylinder 52 and the third cylinder 72 are started again to disengage from the main shaft bushing 22, the booster connecting piece box 23 and the pedal piece 25 respectively, and then the pedal arm 21 is held and moved forward, so that the pedal arm 21 disengages from the clamping block 31 and the pressing block 34, and the brake light switch push rod limit contact piece 24 disengages from the adsorption groove 62, and then the whole vehicle brake pedal body 2 can be disengaged from the fixture forward, so that the vehicle brake pedal body 2 can be conveniently disassembled, which is convenient for the next vehicle brake pedal body 2 to be welded, thereby improving the efficiency of the welding work.

[0069] The above has introduced the present utility model in detail. The description of the specific embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
