Automatic tightening device with position feedback function

Abstract

The invention discloses an automatic tightening device with a position feedback function. The automatic tightening device comprises a workbench (1), a screw tightening device body and a controller. A product clamp (2) is arranged on the workbench (1). A torque sensor (3) is connected to the product clamp (2). The screw tightening device body comprises a servo motor (5), a reducer (6) and a screw sleeve (7). Handles (9) are mounted on the two sides of the reducer (6). The controller comprises a display unit, a control unit, a digital-analog conversion unit, a servo driver and a start switch. The automatic tightening device has the beneficial effects that the automation degree is high, the labor intensity of workers can be lowered, and the working efficiency is improved; precise and quantitative control over the screw tightening torque is achieved, the situation that a screw is not tightened according to the specified force value during manual operation can be prevented, and the product quality is improved; and the automatic tightening device is suitable for automatic tightening of various screws, the torque can be set according to the requirements, and screw mounting is firm and reliable.

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...
