Welding positioner

Abstract

The invention provides a welding positioner which comprises a base, a supporting frame, a deflection motor, a connecting support mechanism, a mounting frame, a fixing base, an angle adjusting assembly, a deflection ring, a rotating motor, a displacement fixing plate, a fixed movement mechanism and a fixing frame mechanism. The effect that a traditional positioner is greatly inclined towards one angle can be achieved through rotation of the deflection motor, a workpiece can be driven to horizontally move within a certain range through movement of the movement air cylinder, and the workpiece can be driven to rotate when the rotating motor rotates; in addition, by controlling the four electric air cylinders to present different heights, the workpiece can present different inclination angles in four directions, the degree of freedom of the whole positioner for driving the workpiece to move is enhanced, and the working efficiency of the positioner is improved. All the fixing heads are tightly attached to the surfaces of the workpieces, and therefore various kinds of workpieces with the special-shaped side faces can be fixed.

Description

technical field [0001] The invention relates to the technical field of welding auxiliary equipment, in particular to a welding positioner. Background technique [0002] The welding positioner is a mechanical device used to drag the workpiece to be welded so that the weld seam to be welded moves to the ideal position and maintains the best welding position. It cooperates with the welding robot to perform welding operations. The welding positioner can ensure the welding quality and improve the welding quality. Welding productivity and the safety of the production process can improve the working conditions of workers. In my country, the welding positioner is a relatively young product. Although compared with the development of foreign countries, the welding positioner started late in China, but the welding structure products are in the machinery industry. At present, the development space of the welding positioner industry in China is still very large. As an indispensable part of...

[0003] The publication number is CN206241564U, which provides a head-to-tail three-axis welding positioner, which can install fixture frames on both sides of the longitudinal beam at the same time, and through the active rotation device respectively arranged at the end of the first beam and the second beam and from the The movable rotating device drives the fixture frame to rotate, and still has the following deficiencies: 1. It can only rotate in one direction, and cannot rotate and move, and the degree of freedom of movement of the entire workpiece to be welded is low during welding; 2. There is no effective workpiece fixing device, and it is only fixed by a rectangular fixture frame with threaded holes. This structure can meet the needs when fixing some relatively regular graphics on the sides, but it can fix some sides that are arc-shaped or irregular. very inconvenient
