A liquid plastic thin-walled sleeve clamp with a return mechanism

Abstract

The invention discloses a liquid plastic thin-walled sleeve fixture with a material return mechanism, which includes a fixing device, a pushing mechanism connected in the fixing device, a linkage clamping mechanism and a linkage ejection mechanism, and the fixing device consists of The fixed guide frame is composed of a transition plate and a clamp body fixedly connected by bolts; the pushing mechanism is composed of a pull rod connected to a slanting block, the slanting block is located inside the fixed guide frame, and the front end of the pull rod is connected to the slanting block, The middle part is connected through the transition plate, the upper end of the inclined block is slidingly connected with the linkage clamping mechanism, and the lower end is rollingly connected with the linkage ejection mechanism; the linkage clamping mechanism and the linkage ejection mechanism are connected to the workpiece. The present invention adopts the structural form in which the push mechanism, the linkage clamping mechanism and the linkage ejection mechanism work together, and combines the flexible clamping function of the liquid plastic to improve the centering accuracy of the workpiece, reduce the workload of workers and machines, and improve the work efficiency.

Description

technical field [0001] The invention relates to a liquid plastic thin-walled sleeve clamp, in particular to a liquid plastic thin-walled sleeve clamp with a material return mechanism, which belongs to the technical field of mechanical processing. Background technique [0002] Self-centering and self-adjusting fixtures are suitable for various machinery manufacturing departments, and their versatility is ubiquitous in machining. The self-centering fixture overcomes the error caused by the reference positioning through step-by-step control, and basically ensures the coaxiality error of the part. Practice has shown that combining the structural characteristics and processing requirements of the parts, the centering accuracy of the workpiece can be greatly improved, the specific requirements of the coaxiality of the parts can be met, and the requirements for centering, positioning and clamping of the workpiece can be realized at the same time. During the tightening process, the...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that when using a liquid plastic centering clamping mechanism to center and clamp a workpiece in the prior art, due to the limited expansion range of the thin-walled sleeve, the accuracy requirements for the positioning hole of the workpiece cannot be met, and the clamping speed is slow. , the problem of complex clamping process, provide a liquid plastic thin-walled sleeve fixture with a material return mechanism, adopt the structural form of the push mechanism, the linkage clamping mechanism and the linkage return mechanism to work together, and combine the liquid plastic The flexible clamping function not only meets the requirements for workpiece positioning and clamping, but also realizes the high-precision centering of the workpiece, and has the function of linked material return, fast clamping speed, less workload and high work efficiency
