Problems solved by technology

[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.

Abstract

The invention discloses a torque-fixed screw fastening apparatus for detecting screw slippage state. The torque-fixed screw fastening apparatus comprises a workbench (1), a screw fastening apparatus and a controller, wherein the workbench (1) is provided with a product clamp(2), which is connected with a torque sensor (3), the screw fastening device comprises a servo motor (5), a decelerator(6) and a screw sleeve (7), handles (9) are installed on the two sides of the decelerator(6), and the controller comprises a display unit, a control unit, a simulated conversion unit, a servo driver and a starting switch. The torque-fixed screw fastening apparatus is high in automation level, lowers labor intensity and improves work efficiency. Accurately quantitative control of screw tightening torque is realized, incapability of following the predetermined force value during manual tightening of a screw can be prevented, and the product quality is improved. The torque-fixed screw fastening apparatus is applicable to automatic tightening of various bolts, torques can be set according to requirement and bolts can be installed firmly and reliably.
