Preferably, the method comprises the following steps:
the method comprises the following steps: firstly, the automobile parts to be clamped are placed between the opposite clamping devices on the left side and the right side, the bottom ends of the automobile parts are in contact with the placing plate, the bottom ends of the automobile parts are placed through the placing plate, after the automobile parts are in contact with the placing plate, the anti-skid rods which are arranged on the inner side surface of the placing plate and in contact with the automobile parts are pressed into the inner side of the placing plate, the anti-skid rods which are not in contact with the automobile parts extend upwards under the elastic force of the third spring, the extending anti-skid rods limit the automobile parts, and the sliding of the automobile parts on the surface of the placing plate is avoided;
step two: when the bottom end face of the automobile part is an inclined face, the multistage electro-hydraulic push rod is started to extend at the same time, so that the multistage electro-hydraulic push rod drives the second transmission rod to incline to a certain angle in the horizontal direction, the second transmission rod pulls the second sliding seat downwards at the moment, the second sliding seat pulls the lifting plate downwards on the inner side of the placing plate through the connecting block, the lifting plate can drive the anti-skid rods to be completely taken into the inner side of the placing plate, and the anti-skid rods are prevented from affecting the sliding of the automobile part on the surface of the placing plate;
step three: then, the multistage electro-hydraulic push rods at different positions are controlled by the controller to shorten and extend to different degrees, so that the multistage electro-hydraulic push rods drive the second transmission rod to rotate by different angles, the second transmission rod can support different positions at the bottom end of the placing plate at different heights after rotating, the angle of the placing plate can be adjusted through the ball socket and the ball head, automobile parts with inclined surfaces at the bottom ends can be conveniently placed, and the sliding of the automobile parts is avoided;
step four: starting the extension of the two-stage electro-hydraulic push rod and the simultaneous shortening of the multi-stage electro-hydraulic push rod, wherein the extension of the two-stage electro-hydraulic push rod drives the placing plate to move upwards, and the shortening of the multi-stage electro-hydraulic push rod drives the second transmission rod to be gradually in a vertical state, so that the stability of the upward movement of the placing plate is ensured, and automobile parts with different heights can be conveniently clamped;
step five: the motor is started, the motor drives the screw rod to rotate through the connecting rod, the screw rod is screwed with the thread of the fixing frame through the screw rod, the screw rod slides on the inner side of the fixing frame in the rotating process, so that the fixed rod slides left and right on the inner side of the fixing frame, the fixed rod can push the fixed plates on the left side and the right side to be close to each other after sliding, the clamping block is enabled to clamp the automobile parts under the elastic force of the first spring, when the screw rod is screwed out of the fixing frame, the connecting rod is arranged on the inner side of the fixing frame at the moment, the fixed rod cannot slide excessively in the fixing frame, and accordingly excessive clamping of the clamping block on the automobile;
step six: when the connecting rod is arranged in the fixing frame, the connecting rod is driven by the fixing base to rotate, so that the connecting rod drives the eccentric gear to rotate through the meshing of the axis gear and the eccentric gear, the eccentric gear drives the sliding block to slide on the inner side of the sliding guide rail after rotating, the sliding block slides and drives the angle of the clamping plate to deflect through the transmission of the first transmission rod, and therefore the clamping plate clamps the side edge of the automobile part, and multi-angle clamping is achieved;
step seven: when automobile parts do not need to be clamped, the starting motor rotates reversely, the screw rod can be always in contact with the fixing frame under the elastic force of the first spring, the motor drives the screw rod to rotate, so that the screw rod can move reversely in the fixing frame and can be completely screwed into the inner side of the fixing frame, the fixing rod drives the fixing plate and the clamping block to be away from each other, the screw rod can drive the connecting rod to slide when being screwed into the inner side of the fixing frame, the axis gear is not meshed with the eccentric gear, and the clamping plate rotates and is located on the same plane with the fixing frame under the tensile force of the second spring, so that the automobile parts are not clamped.
Compared with the prior art, the invention has the beneficial effects that:
1. according to the automobile part clamping device, the connecting rod can drive the screw rod to rotate through the operation of the motor through the arranged opposite clamping device, the screw rod slides on the inner side of the fixing frame in the rotating process through the screwing of the screw rod and the fixing frame, so that the fixing rod slides left and right on the inner side of the fixing frame, the fixing rod can push the fixing plates on the left side and the right side to be close to each other after sliding, the clamping block is used for clamping automobile parts under the elastic force of the first spring, and after the screw rod is screwed out of the fixing frame, the connecting rod is arranged on the inner side of the fixing frame at the moment, so that the excessive clamping of the clamping block on the automobile parts is;
2. according to the automobile part clamping device, through the arrangement of the opposite clamping device and the side clamping device, when the connecting rod is arranged in the fixing frame, the fixing base drives the connecting rod to rotate, so that the connecting rod drives the eccentric gear to rotate through the meshing of the axis gear and the eccentric gear, the eccentric gear drives the sliding block to slide on the inner side of the sliding guide rail after rotating, the sliding block slides and drives the angle of the clamping plate to deflect through the transmission of the first transmission rod, and therefore the clamping plate clamps the side of an automobile part, and multi-angle clamping is achieved;
3. according to the automobile part clamping device, the bottom end of the automobile part is placed through the placing plate through the bottom placing device and the anti-skidding device, the phenomenon that the automobile part inclines in the clamping process due to the fact that the automobile part slides on the surface of the placing plate is avoided through the anti-skidding device, the bottom end of the automobile part with the bottom end face being the inclined face can be attached to the placing plate through deflection of the placing plate, the contact area between the placing plate and the automobile part is increased, and therefore the possibility that the automobile part inclines after being mistakenly touched is further reduced.
