Problems solved by technology

In the process of tightening with an electric torque wrench, some installation spaces are limited and hand tools cannot be fixed, which will increase the difficulty for operators
During the operation, there are the following problems: because the workers need to hold the glasses wrench to prevent rotation, the labor intensity of the workers is increased, resulting in low production efficiency. When the torque of the electric wrench is too large, the worker may not be able to hold the wrench. There will be safety hazards, and there will be false fastening phenomena at the same time, and the qualified rate of product assembly quality will be low

Embodiment approach

[0018] Connect the balancer through the round hole of the positioning clamp 11, and hang a follow-up anti-torque device on the assembly station of the automobile production line. When the car body to be assembled is transported to this station, the worker puts the nut in the sleeve 1 with his left hand. Hold the electric wrench in your right hand to bring the bolt into the nut, then hold the handle 7 of the follow-up anti-torque device with your left hand, and operate the electric wrench to rotate with your right hand. A follow-up sliding body 3 of a follow-up anti-torque device is guided by the ball slide rail and the guide post, and it also moves forward. After reaching a fixed torque, the electric wrench stops working, the right hand withdraws the electric wrench, and the left hand reverses. Once pulled, a follow-up sliding body 3 of a follow-up anti-torque device resets, and this operation completes the work.

Abstract

The invention relates to a follow-up counter torque device. The follow-up counter torque device comprises a sleeve, a connecting head, a follow-up sliding body, a first limiting plate, a sliding block, a connecting body, a handle, a guide rail, a guide column, a second limiting plate, a positioning clamping plate and a wrench guide plate. Under the double guide of a rolling ball slide rail and theguide column sliding, the sleeve positions a nut to follow the follow-up sliding body to move ahead, after reaching a fixed torque, an electric wrench stops working, and the fixed torque tightening abolt without an anti-rotating device is realized; and meanwhile, according to the thread precession length, the sleeve and a wrench are follow-up, the production safety and product assembly quality are ensured, the labor intensity of workers is effectively reduced, the follow-up counter torque device is very suitable for product mass assembly line assembly operation, and the assembly work under the condition that an operation space is narrow and a manual tool can not be fixed is solved.

Description

technical field [0001] The invention relates to the field of automobile manufacture and assembly, in particular to a follow-up anti-torque device. Background technique [0002] In the process of automobile manufacturing and assembly, many detachable connections between parts are in the form of threaded connections, and some of them are directly fixed on the product parts by welding nuts or bolts, so that no external force is needed during the tightening and tightening process. Anti-rotation, directly connect the two parts, the other part is the nut and the bolt exist independently, because there is no anti-rotation device in the two ends, in the process of tightening, the bolt or the nut will rotate. In the process of tightening with an electric torque wrench, some installation spaces are limited and hand tools cannot be fixed, which will increase the difficulty for operators. During the operation, there are the following problems: because the workers need to hold the glass...
