Mechanical arm

Abstract

The invention discloses a mechanical arm. The mechanical arm comprises a horizontal movement mechanism, a horizontal movement body, a vertical movement mechanism, a vertical movement body, a clampingdriving mechanism for driving clamping or loosening of clamping arms and the clamping arms. The horizontal movement mechanism comprises two parallel and horizontally placed guide rails and a horizontal driving mechanism. The vertical movement mechanism comprises a first telescopic cylinder. The horizontal movement mechanism moves along the two guide rails through the horizontal driving mechanism to drive the horizontal movement body to move horizontally. The first telescopic cylinder is vertically installed between the horizontal movement body at the upper end and the vertical movement body atthe lower end. The fixed end of the first telescopic cylinder is installed in the horizontal movement body, the telescopic end of the first telescopic cylinder is fixedly connected with the verticalmovement body, and the vertical movement of the vertical movement body is driven by the expansion and contraction of the first telescopic cylinder. The clamping arms are arranged on the vertical movement body. The mechanical arm has a symmetrical structure, can realize stable movement of the horizontal movement body, and can effectively control the depth and the clamping degree of clamped materials.

Description

technical field [0001] The invention belongs to the field of mechanical automation, in particular to a mechanical arm. Background technique [0002] The mechanical arm is a mechatronic device that simulates the functions of the human arm, wrist and hand; it can move any object or tool according to the time-varying requirements of the spatial posture (position and posture), so as to complete the operation requirements of an industrial production, such as Holding welding tongs or torches, performing spot welding or arc welding on automobile or motorcycle bodies, handling die-casting or stamping parts or components, performing laser cutting, spraying, assembling mechanical parts, etc.; in industrial manufacturing, medical treatment It can be seen in fields such as military, entertainment services, military, semiconductor manufacturing, and space exploration. Although their shapes are different, they all have a common feature, that is, they can accept instructions and accuratel...

Problems solved by technology

The main manifestations are: (1) The distribution of motion commands is inaccurate, and the respective motion ratios of the moving guide rail and the robot arm often need to be adjusted manually, which prolongs the working time; (2) The movement mode of the mobile base on the guide rail lacks fine cont
