floating fixture

Abstract

The invention discloses a floating type clamp. An object clamping cylinder comprises an object clamping cylinder body. Two first pistons are arranged in the object clamping cylinder body. Each first piston is connected with a first piston rod. Each first piston rod is fixedly connected with a jaw. The two jaws are arranged oppositely. The clamp further comprises a locating and clamping body provided with two clamping portions, and the clamping portions are connected with the object clamping cylinder body in a rotary manner. The floating type clamp further comprises a locating and clamping cylinder. The locating and clamping cylinder comprises a locating and clamping cylinder body. The locating and clamping cylinder body is internally provided with a second piston. The second piston is connected with a second piston rod. The locating and clamping cylinder body and the second piston rod are each fixedly connected with the corresponding clamping portion of the locating and clamping body. By means of the floating type clamp of the structure, a clamped workpiece can be clamped in the first place and then located; in addition, the clamping portions are connected with the object clamping cylinder body in a rotary manner; and the floating type clamp conducts alignment and clamping freely with variation of the fulcrum of the clamped workpiece and then conducts location, deformation of the workpiece can be effectively avoided, and the quality qualification rate of the machined workpiece is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of clamping and processing equipment, and in particular relates to a floating clamp. Background technique [0002] With the transformation and upgrading of the industrial equipment manufacturing industry and the application of robot handling and clamping technology, the requirements for tooling fixtures have developed in the direction of high-end, professional and intelligent. Especially in the field of processing some light workpieces (or welded parts), due to the poor rigidity of the workpiece itself, the narrow space for grasping and clamping, and the poor quality of the clamped surface, it is very easy to appear clamping rebound deformation, resulting in The pass rate of workpiece processing accuracy is reduced, and the manufacturing cost is greatly increased.

AI Technical Summary

Problems solved by technology

Especially in the field of processing some light workpieces (or welded parts), due to the poor rigidity of the workpiece itself, the narrow space for grasping and clamping, and the poor quality of the clamped surface, it is very easy to appear clamping rebound deformation, resulting in The pass rate of workpiece machining accuracy is reduced, and the manufacturing cost is greatly increased

[0003] At present, light-weight components such as solar concentrating glass plate brackets are prone to deformation during the welding process, or due to the error of the welding surface, when the workpiece is clamped, the workpiece will be deformed due to the deformation of the fulcrum. After clamping, torque rebound is easy to occur after the machining operation is completed, which will cause machining errors and affect the machining accuracy of the workpiece

Or because the workpiece is clamped and grasped by the manipulator, the clamping surface between the manipulator and the workpiece is unstable, resulting in the deformation of the grasped workpiece, which affects the quality pass rate of the workpiece
