High-thrust-point bench clamp

Abstract

The invention provides a high-thrust-point bench clamp which comprises a bench clamp track, a fixed clamp port and a moving clamp port. The fixed clamp port is fixed on the bench clamp track, the moving clamp port is arranged in the bench clamp track in a sleeved mode, a clamp port thrust device is connected to the moving clamp port, the moving clamp port can slide on the bench clamp track under the thrust of the clamp port thrust device, and the force bearing point, thrust by the clamp port thrust device, of the moving clamp port is higher than the matching surfaces of the moving clamp port and the bench clamp track. Through the above manner, the problem that the sliding working surface of the moving clamp port is stressed unevenly is solved according to the force analysis of the moving clamp port in the actual using process, the force situation of the moving clamp port is balanced, the working precision of the bench clamp is improved, and the service life of the bench clamp is prolonged.

Description

technical field [0001] The invention relates to the field of mechanical fixture design, in particular to a vise with a high thrust point. Background technique [0002] The structure of the vise is mainly composed of movable vise body, fixed vise body, base and other parts. The movable tong body is installed on the fixed tong body, and the movable tong body is driven to move in the groove of the fixed tong body by a screw rod with trapezoidal thread, so that the jaws can be opened and closed. The fixed clamp body is connected on the base, and the base is fixed on the bench by bolts. There has been a lot of research on the selection of the force point of the movable vise body and the screw rod. In a common vise, the connection between the screw rod and the movable vise body is located under the sliding working surface of the movable vise body, and the movable vise body clamps the workpiece when it is clamped. , and the force point of the workpiece is located above the slidi...

Problems solved by technology

There has been a lot of research on the selection of the force point of the movable vise body and the screw rod. In a common vise, the connection between the screw rod and the movable vise body is located under the sliding working surface of the movable vise body, and the movable vise body clamps the workpiece when it is clamped. , and the force point of the workpiece is located above the sliding working surface, so it is easy to form a turning moment, which will cause uneven force damage to the vise and reduce its service life
