The fixing seats for placing the automobile tappet bodies are arranged on the bottom plates corresponding to the two ends of the pressing plate, and the automobile tappet bodies are pressed between the corresponding fixing seats and the corresponding ends of the pressing plate under the working state.
According to a further improvement scheme of the invention, V-shaped grooves which longitudinally penetrate through two ends of the fixing seat are formed in the upper surface of the fixing seat, and the V-shaped grooves on the two fixing seats are longitudinally parallel. A pin seat is fixed on a bottom plate at one end of the fixed seat, a pin hole is formed in the pin seat, a sealing cover is arranged at one end of the pin hole, which is not adjacent to the fixed seat, and a spring and a push head are arranged in the pin hole; the push head is a short rod, the inner end of the push head is propped against one end of the spring, and the outer end of the push head is propped against the non-hole end of the automobile tappet body when in operation.
The invention further improves the scheme that the other end of the fixing seat is provided with an auxiliary pressing plate strip, and one end of the auxiliary pressing plate strip is pressed on the holed end of the automobile tappet body. A supporting block is arranged under the other end of the auxiliary pressing strip. An auxiliary pressing cylinder is arranged on one longitudinal side of the auxiliary pressing strip, the auxiliary pressing cylinder is a lever cylinder, a cylinder body of the lever cylinder is fixed on the bottom plate, and the outer end of the lever is pressed in the middle of the longitudinal direction of the auxiliary pressing strip.
According to a further improvement scheme, the inner side and the outer side of the auxiliary pressing plate strip are respectively provided with an inner baffle plate and an outer baffle plate.
In a further development of the invention, the support block has a flat-bottomed pit, the pit wall of the flat-bottomed pit adjacent to the auxiliary pressing plate strip has a notch, the width of the notch is adapted to the width of the auxiliary pressing plate strip, and the end of the auxiliary pressing plate strip is abutted against the opposite pit wall through the notch.
According to the scheme, the oil cylinder is arranged on the bottom plate, the piston rods of the oil cylinders face upwards, and the cylinder body of the oil cylinder is fixed on the bottom plate. The upper end of the piston rod is connected with a pressing plate, two ends of the pressing plate extend out of the bottom plates corresponding to two ends of the pressing plate on two sides of the oil cylinder, fixing seats for placing the automobile tappet body are arranged on the bottom plates, and the automobile tappet body is pressed between the corresponding fixing seats and the corresponding ends of the pressing plate under the working state. The positioning of two automobile tappet bodies can be realized by utilizing one oil cylinder, and if two or more oil cylinders are arranged on one bottom plate, the positioning of two or more automobile tappet bodies can be realized simultaneously. Compared with the prior art that only one automobile tappet body can be clamped at a time, the trouble of frequently replacing the automobile tappet body is avoided, and the production efficiency is greatly improved. And because the positioning of the automobile tappet body is realized by adopting the oil cylinder, the pressure of the oil cylinder is larger, and the movement of the processed automobile tappet body can be avoided in the processing process, thereby improving the processing quality of products.
