Problems solved by technology

This method is more likely to cause the three-jaw chuck to not clamp the seat shell tightly during the operation, and the tightening operation cannot be completed, or the three-jaw chuck clamp seat shell is too tight to damage the surface of the part and affect the product qualification rate; the seat shell and the seat outer shell The thread accuracy of the body is high, which is a precision fit. If the operator applies uneven force or deflection, it is easy to cause thread biting phenomenon, resulting in thread damage and redundant parts or even scrapped parts. At the same time, this method is cumbersome to operate and requires Higher, lower assembly efficiency, not conducive to fast-paced assembly line production

Embodiment

[0022] Such as figure 1 As shown, 1) Preparation before tightening: adjust the adjusting nut 37 of the torque limiter 3 to set the maximum output value of the torque limiter 3; adjust the adjusting nut 46 of the clamping device 4: ensure that the clamping sleeve is in the clamped state The hole center of 47 is coaxial with the torque limiter output port hole;

[0023] 2) After screwing the part seat shell into the 1-3 screw buckles of the seat external shell, the seat shell is clamped by the clamping sleeve 47, and the seat external shell is inserted into the output end 32 of the torque limiter;

[0024] 3) Start the motor;

[0025] 4) The torque limiter 3 drives the seat outer shell to rotate, so that the seat shell is screwed into the seat outer shell;

[0026] 5) After the thread is screwed to the set torque, the output end 32 of the torque limiter stops rotating;

[0027] 6) When the clamping device 4 is clamping the housing of the seat, the external housing of the seat...

Abstract

The invention discloses an efficient tightening device for quick coupling assembly. The device comprises a base, a driving device with a reduction gearbox, a moment limiter and a clamping device, wherein the driving device is fixedly mounted on the base, the moment limiter is rigidly connected with the driving device, and the clamping device is movably connected with the base; and the tightening torque can be quantitatively controlled, precise thread assembly between parts can be completed, the reject ratio of product assembly is greatly reduced, meanwhile, the operation is easy, and the product assembly efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical tools, in particular to an efficient tightening device for quick joint assembly. Background technique [0002] During the assembly process of the quick connector, the two parts of the seat shell and the seat external shell are connected by thread pairs, and must be screwed together under a certain torque. In conventional operation, a three-jaw chuck is used to clamp the cylindrical surface of the seat shell, and a torque wrench is applied to the six sides of the shell outside the seat to screw the thread to the bottom and reach a certain torque. This method is more likely to cause the three-jaw chuck to not clamp the seat shell tightly during the operation, and the tightening operation cannot be completed, or the three-jaw chuck clamp seat shell is too tight to damage the surface of the part and affect the product qualification rate; the seat shell and the seat outer shell The thread accuracy ...
