Fed and discharged material clamping device in engine crankshaft machining

Abstract

The invention discloses a fed and discharged material clamping device in engine crankshaft machining, aiming at solving the problem of positioning and clamping crankshaft workpieces when being fed and discharged. The clamping device comprises an execution mechanism, a driving mechanism, a positioning block and a workpiece identifying mechanism, an installing plate and a PLC (Programmable Logic Controller) control system, wherein the execution mechanism is composed of guide tracks, slide blocks, clamping arms and a clamping base; the guide tracks are symmetrically arranged at left and right and are fixed on the installing plate; the sliding blocks are assembled at the front and back ends of the guide track at each side; the clamping arm comprises a front clamping arm which is assembled with two slide blocks at the front end and a rear clamping arm which is assembled with two slide blocks at the rear end; the clamping base comprises a crankshaft flange end sleeve base and a crankshaft front end sleeve base; the crankshaft flange end sleeve base is embedded at the lower end of the front clamping arm; and the crankshaft front end sleeve base is embedded at the lower end of the rear clamping arm. The clamping device has the characteristics of simple structure, convenience in maintenance, low manufacturing cost and accurate positioning, the workpiece is prevented from being collided or scratched when being fed and discharged, the working intensity of operation personnel is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a workpiece clamping device, in particular to a clamping device for engine crankshaft processing loading and unloading tooling, and belongs to the technical field of mechanical equipment. Background technique [0002] The engine crankshaft is a product with irregular shape. During the machining process of the engine crankshaft, the loading and unloading of the crankshaft workpiece is generally carried out manually, which not only has the defects of high labor intensity and low work efficiency for operators; but also due to the lack of effective Positioning measures can easily cause problems such as bumping and scratching of the workpiece, placement of the workpiece posture, and wrong model identification, which will adversely affect the quality of the crankshaft workpiece. Contents of the invention [0003] The object of the present invention is to solve the positioning problem of the crankshaft workpiece in the process of lo...
