Workpiece fastening and clamping mechanism

Abstract

The invention discloses a workpiece fastening and clamping mechanism. The workpiece fastening and clamping mechanism comprises a working platform, a support frame and a hold-down component, wherein the support frame comprises uprights and a transverse support beam; the hold-down component comprises a lift cylinder, a connecting plate, pressure blocks I, a pressure block II and a buffer piece; thelift cylinder is fixed at the bottom of the transverse support beam; the connecting plate is fixed to the end part of a piston rod of the lift cylinder; the pressure blocks I, the pressure block II and the buffer piece are fixed at the bottom of the connecting plate; the two pressure blocks are symmetrically arranged on two sides of the buffer piece; two jacking blocks are arranged on the top surface of the working platform and respectively located right below the corresponding pressure blocks; an arc-shaped notch portion is formed in the lower end of each of the two pressure blocks I; a bulbI matched with the corresponding arc-shaped notch portion is arranged at the upper end of each the two jacking blocks; a bulb II is arranged at the lower end of the pressing block II; and the workingplatform is provided with a concave cavity matched with the bulb II. The workpiece fastening and clamping mechanism is simple in structure and convenient to use, realizes efficient and quick fasteningof a workpiece, and can achieve stamping operation, the production efficiency is improved, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a fastening and clamping mechanism for 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 a workpiece fastening and clamping mechanism that is simple in structure, easy to use, realizes efficient and fast fastening of workpieces, and can realize stamping oper...
