Abstract

The invention relates to an automatic tightening machine for a nut for a car horn bracket. The automatic tightening machine comprises a fixed die carrier formed by guide columns (4), guide sleeves (5), an upper template (20) and a lower template (23), wherein a movable template (6) is arranged between the upper and lower templates (20) and (23) and slides along the guide columns, and a lifting cylinder (1) is arranged on the upper template (20); the movable template (6) is connected with a piston rod of the lifting cylinder (1), and a torque sensor (3) is arranged on the movable template (6); one end of the torque sensor (3) is connected with a servo drive (2), and the other end of the torque sensor (3) is connected with a speed reducer(18); and the speed reducer (18) is arranged on a mounting plate (24), and the mounting plate (24) is connected with the movable template (6); and the other end of the speed reducer (18) is connected with an output shaft (17) through a connecting shaft sleeve (19). The horn bracket can not be shaken off, the sound quality of a horn can not be changed, and the machine is convenient to install, can be combined with a production line and meets the needs of different batches of production.

Description

technical field [0001] The invention relates to a nut tightening machine, in particular to an automatic nut tightening machine for automobile horn brackets. Background technique [0002] Existing automobile horn support nut is tightened, and what mainly adopt is that nut tightening machine is finished. There are two main forms of using a nut tightening machine: one is the manual form. That is to put the horn into the fixture for positioning first, and put in the screws and brackets, then send the nuts to the connecting shaft sleeve of the nut tightening machine, and finally tighten the nuts to the horn brackets by the electric or pneumatic nut tightening machine. This kind of manual mode, compared with the nut tightening machine that places the horn with both hands first, and then pulls the electric or air batch with one hand, has low efficiency, large difference in tightening torque, and the bracket is easy to shake off. Seriously, if the tightening force of the nut is not...
