AI Technical Summary
Technical Problem
Existing valve body machining equipment uses a single-end clamping method, which makes it difficult to balance multi-directional cutting forces, causing the valve body to shake and shift during machining, affecting machining accuracy and efficiency.
Method used
A multi-axis clamping device including transverse and longitudinal clamping mechanisms was designed. By using components such as support rods, cams, gears and bidirectional lead screws, the valve is fixed in multiple axes by its own weight and driven by a servo motor, thereby improving stability.
Benefits of technology
This improved the stability and precision of the valve body during processing, reducing product defect rates and production costs.

Abstract
The utility model discloses a multi-shaft clamping device for processing a valve shell, a transverse clamping mechanism comprises supporting rods fixedly connected to four corners of the top of a base, one side of each supporting rod is rotatably connected with a cam, one sides of two cams are fixedly connected with first gears, and the other sides of the two cams are fixedly connected with second gears. One side of each first gear is connected with a second gear in a meshed mode, a first connecting rod is rotationally connected between the two opposite cams, one end of each first connecting rod penetrates through one side of the corresponding cam to be fixedly connected with one side of the corresponding second gear, and the middle of the outer wall of each first connecting rod is fixedly connected with a second connecting rod. When the two ends of the valve are placed on the fixing rings, under the pressure of the dead weight of the valve, the cams on the two sides can be driven to swing downwards, the partition plates on the two sides can be driven to gather inwards, the two sides of the valve can be fixed in the first step, and under the action of the dead weight of the valve, no driving source needs to be used; preliminary clamping treatment can be carried out on the workpiece only through the partition plates on the two sides.
