Description
- This application claims priority to Chinese Patent Application No. 201710443133.X, filed on Jun. 13, 2017, which is hereby incorporated by reference in its entirety.
- The present invention relates to a fixture, and specifically, relates to an improved automobile hub lathe fixture.
- In the automobile hub lathe machining production, an automobile hub needs to be positioned and clamped for turning, and clamping jaws of a common hydraulic lathe fixture are often damaged due to too large hydraulic pressure.
- An improved automobile hub lathe fixture includes a central positioning pin, wheel lip positioning pins, clamping jaws, supports, hinge pins, connecting nuts, connecting screws, lifting pins, tension springs, a three-leaf disc cam, a guide sleeve, a gear rotating shaft, a rack ejector rod, a cylinder and a fixture body frame.
- The central positioning pin is arranged in a fixture body center sleeve, the wheel lip positioning pins are arranged on the same pitch circle of a fixture body, the clamping jaws are connected to the supports via the hinge pins, the supports and the fixture body frame are casted into a whole, the connecting screws are fixed at the lower ends of the clamping jaws via the connecting nuts, the lifting pins are arranged in guide sleeves, the bottoms of the clamping jaws are connected to the fixture body frame by the tension springs, and the tension springs keep the clamping jaws in a splayed state when the clamping jaws are not clamping a workpiece. The three-leaf disc cam is arranged on top half of the gear rotating shaft, the gear rotating shaft is arranged in the guide sleeve of the fixture body frame, and the rack ejector rod is connected with the cylinder.
- In the present invention, a piston rod of the cylinder drives the rack ejector rod to move linearly, the rack ejector rod drives the gear rotating shaft to rotate via tooth connection, the reducing characteristic of a cam contact face is realized by horizontal rotation of the three-leaf disc cam, a limiting raised part is added to the three-leaf disc cam to prevent excessive rotation of the three-leaf disc cam so as to complete the ejection function of the lifting pins, and the clamping jaws rotate in the hinge pins to clamp an automobile hub.
- The improved automobile hub lathe fixture of the present invention can save the manpower and materials and further improve the production efficiency.
