Clamp

Abstract

The invention provides a clamp. The clamp comprises a right clamping plate, a left clamping plate, a dual-way screw, a left sleeve block, a right sleeve block, a right fixed plate, a sleeve rod, a hollow block, a rotating block, a first screw, a left fixed plate and a bolt; the left sleeve block is arranged on the lower end of the left clamping plate, the left sleeve block is arranged on a dual-way screw, the right sleeve block is arranged at the lower end of the right clamping plate, the right sleeve block is assembled on the dual-way screw. Through design, a workpiece can be conveniently clamped, the right fixed plate is arranged on the right end of the sleeve rod, the sleeve rod is assembled on the right end of the rotating block, the sleeve rod is arranged on the hollow block, the rotating block is arranged on the hollow block, the bolt is arranged on the lower end of the rotating block, the first screw is arranged on the sleeve rod, the first screw is arranged on the rotating block, and the first screw is arranged on the right end of the le ft fixed plate. Through the design, the clamp can be conveniently fixed and dismounted, use is convenient, operation is convenient, time and labor are saved, and the use effect is high.

Description

technical field [0001] The invention is a fixture, which belongs to the technical field of numerical control processing. Background technique [0002] In the prior art, the double forks are used for sprinkler irrigation, natural gas, oil pipeline transportation, etc., and the holes on the fork tubes are usually processed by four-axis machining centers. The double forks are special-shaped parts, so special fixtures must be designed for positioning and clamping; currently The upper and lower positioning of the middle insert is mainly used; manual tightening with nuts results in low clamping efficiency and high labor intensity. It is very necessary to design a clamp that is convenient for clamping, accurate in positioning, consistent in clamping force, and reduces hole deformation. [0003] Most of the existing fixtures use multiple bolts to drive the splint to clamp the workpiece. The operation steps are complicated, the operation process is laborious, and it takes time and ef...

[0002] In the prior art, the double forks are used for sprinkler irrigation, natural gas, oil pipeline transportation, etc., and the holes on the fork tubes are usually processed by four-axis machining centers. The double forks are special-shaped parts, so special fixtures must be designed for positioning and clamping; currently The upper and lower positioning of the middle insert is mainly used; manual tightening with nuts results in low clamping efficiency and high labor intensity. It is very necessary to design a fixture that is convenient for clamping, accurate in positioning, consistent in clamping force, and reduces hole deformation.

[0003] Most of the existing fixtures use multiple bolts to drive the splint to clamp the workpiece. The operation steps are complicated, the operation process is laborious, and it takes time and effort to use. Most of the existing fixtures are fixed on the lathe with bolts, which is not easy to disassemble and install, and cannot be rotated. Fixtures, resulting in the need to re-clamp and calibrate the milling head when processing other surfaces, the use effect is poor
