Adjustable clamping device for workpiece fastening

Abstract

The invention discloses an adjustable clamping device for fastening workpieces, which includes a working platform, a support frame and a pressing assembly. The support frame includes a door-shaped bracket and a horizontal support beam. At the bottom of the middle of the support beam, the connecting plate is fixed on the end of the piston rod of the vertical cylinder. There are two pressing blocks I, which are respectively located at the two ends of the connecting plate. The buffer and the buffer are fixed on the bottom of the connecting plate. Two top blocks are arranged on the top surface of the working platform, and the two top blocks are respectively slidably arranged on the working platform along the transverse direction. The opposite sides of the lower ends of the two pressing blocks 1 are respectively provided with arc-shaped gaps. The upper ends of the two top blocks have ball heads I respectively, the lower ends of the pressure block II have ball heads II, and the top surface of the working platform is provided with concave cavities. The invention can not only realize high-efficiency and fast buckling of workpieces, but also can freely adjust according to the size of the workpieces, has a wide application range, can also realize punching operations, improve production efficiency and reduce costs.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to an adjustable clamping device for fastening workpieces. Background technique [0002] In the process of assembling plate workpieces in the field of machining, it often occurs that the fastening of some workpieces requires fine fastening technology. If a special mold is developed for this kind of workpiece, it will require a large amount of tooling costs, and the mold is heavy. At the same time The workpiece usually needs to be stamped by stamping equipment during assembly, but the use of stamping equipment not only increases time consumption and reduces production efficiency, but also takes up relatively large capital and equipment resources and increases costs. [0003] Therefore, there is an urgent need to develop an efficient and fast fastening of workpieces, which can be freely adjusted according to the size of the workpieces, has a wide range of applications, can also real...
