Active clamping delivery mechanism

Abstract

The invention aims to provide an active clamping delivery mechanism comprising a main driving device, an auxiliary driving device, a pair of main sliding rails arranged symmetrically, main attachments connected to the main sliding rails and the main driving device, gripping jaws, and auxiliary attachments connected to the gripping jaws and the auxiliary driving device; the gripping jaws are movably connected to the auxiliary attachments movably, and arranged on the main sliding rails; the gripping jaws are arranged between the two main sliding rails symmetrically; and at least one of the two gripping jaws arranged symmetrically is movably arranged on the main sliding rail, and can only do rectilinear motion in the direction toward or opposite to the gripping jaw symmetrical to the gripping jaw movably arranged on the sliding rail. According to the active clamping delivery mechanism provided by the invention, the gripping jaws are driven by linear motors, so that the purpose of active clamping of the gripping jaws is achieved, the sliding contact between the gripping jaws and workpieces is avoided, and the surface quality of the workpieces is ensured; the sliding rails can be driven by the linear motors directly, and the dynamic response performance, positioning accuracy, transmission stiffness and transmission efficiency of a system are improved; and the running noise is reduced.

Description

technical field [0001] The invention relates to the field of production equipment, in particular to a clamping transmission mechanism. Background technique [0002] In the field of bearing manufacturing, the current transmission mechanism generally uses a cam or a servo motor to drive the slide rail, and the cam or servo motor provides the transmission pull and thrust. The slide rails are set in pairs, and the jaws are installed on the slide rails. There is a spring between the jaws and the slide rails. The workpiece is fixed by pressing the workpiece into the middle of a pair of jaws. After the workpiece is taken out, the spring rebounds to realize clamping. Claw reset. Since the opening and closing of the jaws is realized by the compression and rebound of the spring during the process of fixing the workpiece by the jaws, there is sliding contact between the jaws and the surface of the workpiece. During the sliding contact process, it is easy to cause scratches on the surf...

Problems solved by technology

Since the opening and closing of the jaws is realized by the compression and rebound of the spring during the process of fixing the workpiece by the jaws, there is sliding contact between the jaws and the surface of the workpiece. During the sliding contact process, it is easy to cause scratches on the surface of the workpiece and affect the surface of the product. quality
