Problems solved by technology

However, there is a problem of unstable transmission in the control of the turning motion of the worktable. For workpieces of different weights, it is difficult to achieve constant speed and smooth operation. Configure the drives and transmissions with higher precision, which leads to higher cost of the positioner

Abstract

The invention discloses a positioner with a torsion adjusting device. The positioner comprises a fixed seat (1) and a tilting seat (2). The tilting seat (2) is connected with an output shaft of a tilting driver (4). A torsion adjusting device is further disposed in the tilting seat (2) and comprises a screw (6), a weight A (7) and a nut (8). The weight A (7) is sleeved on the screw (6). The nut (8) is disposed on the screw below the weight A (7). A thrust ball bearing (10) is arranged on the upper portion of the screw and is disposed in a bearing block of the tilting seat (2). The positioner has the advantages that the positioner is simple in structure, convenient to adjust, low in manufacturing cost, easy to assemble and stable in performance; the position of the weight A on the screw is adjusted to adjust initial torque of the positioner so that the positioner is adaptive to workpieces different in weight, tilting is constant in speed and stable and insusceptible to workpiece weight, and application range of the positioner is widened.

Description

technical field [0001] The invention relates to welding auxiliary equipment, especially a positioner with a torque adjustment device. Background technique [0002] The positioner is a special welding auxiliary equipment, which is suitable for the welding position of the rotary work, so as to obtain the ideal processing position and welding speed. It can be used in conjunction with manipulators and welding machines to form an automatic welding center, and it can also be used for workpiece displacement during manual operations. The rotary of the workbench adopts the stepless speed regulation of the frequency converter, and the speed regulation precision is high. [0003] The welding positioner is generally composed of a table turning mechanism and a turning mechanism. Through the turning and turning of the worktable, the workpiece fixed on the worktable can reach the required welding and assembly angle. Satisfactory welding speed. However, there is a problem of unstable tra...
