Automatic tightening device with position feedback function

Abstract

The invention discloses an automatic tightening device with a position feedback function. The automatic tightening device with the position feedback function comprises a workbench (1), a screw tightening device and a controller. The workbench (1) is provided with a product clamp (2) connected with a torque sensor (3). The screw tightening device comprises a servo motor (5), a speed reducer (6) and a screw sleeve (7). Handles (9) are installed on the two sides of the speed reducer (6). The controller comprises a display unit, a control unit, a digital conversion unit, a servo driver and a starting switch. The automatic tightening device with the position feedback function has the beneficial effects that the degree of automation is high, the labor intensity of workers can be relieved, and working efficiency is improved; accurate and quantitative control over the screw tightening torque is achieved, it can be avoided that screws are not tightened according to the stipulated force value in the manual operation process, and the product quality is improved; the automatic tightening device is suitable for automatically tightening various bolts, the torque can be set as needed, and bolts are installed firmly and reliably.

Description

technical field [0001] The invention relates to the technical field of screw tightening devices, in particular to an automatic tightening device with a position feedback function. Background technique [0002] In the current assembly process of parts and devices, the tightening operation of bolts and other fasteners is mostly done manually, with low degree of automation, high labor intensity, and low production efficiency. In addition, during manual operation, the torque depends entirely on the operator's feeling control, the torque value of tightening the screw cannot be accurately controlled; the existing torque wrench can realize the tightening of the screw according to the specified torque value, but the function is single, the limit value cannot be adjusted, the cost is high, and the production efficiency is also low, which cannot meet the needs of large-scale batch processing. Require. Contents of the invention [0003] The purpose of the present invention is to ove...
