Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of workpiece clamping, in particular to a four-station fixture platform. Background Art
[0002] Traditional CNC lathe machining has low efficiency for small structural parts like clevis pins. Only one part can be processed at a time, and manual loading and unloading of parts and three tool changes are required to complete the drilling, reaming, and boring processes. To significantly improve efficiency, multiple machining processes need to be centralized on a four-station rotary modular lathe. The four-station clamping platform typically consists of a base plate, column, cover, cylinder, piston rod, pressure plate, pressure block, guide sleeve, guide rod, bracket, and ejector pin.
[0003] The power source of the fixture usually comes from a hydraulic station. CNC lathes are precision processing devices. During the hydraulic drive process, multiple fixtures can work synchronously but cannot work independently. When only a single small part needs to be processed, independent clamping cannot be achieved, which wastes power and lacks flexibility. Moreover, during the clamping process, the contact between the fixture and the workpiece will generate a large impact force, which may cause damage to the workpiece surface. Utility Model Content
