The technical scheme of the utility model is that:

the utility model provides an automatic equipment is screwed up in upset, includes suspension device, screws up equipment and tipping arrangement, and the three is vertical distribution on the whole, and linkage is last, screws up equipment in the centre, and the tipping arrangement is down, screws up the equipment and fixes on suspension device, and suspension device passes through the pulley and slides along the track of its top, its characterized in that: the suspension device is provided with a lifting cylinder which can drive the suspension device to lift, the tightening device is provided with an electric tightening shaft, an STC (serial time code) controller and a torque signal detection unit, the electric tightening shaft consists of a motor, a planetary gear reducer and a torque sensor, and the STC controller is used for input detection and output control of signals and data processing; the torque signal detection unit is used for detecting the torque borne by the electric tightening shaft and ensuring the accuracy of the torque;

the turnover equipment comprises an alternating current motor, a left rotating shaft, a turnover table, a right rotating shaft, a right support and a left support, wherein the left support and the right support are vertically arranged on the ground in parallel and used for supporting other components, the left rotating shaft is arranged on the left support, the right rotating shaft is arranged on the right support, the turnover table is positioned between the left support and the right support, and the alternating current motor drives the left rotating shaft to rotate so as to drive the turnover table to rotate.

The whole equipment is in a vertical suspension structure mode and comprises suspension equipment, tightening equipment and turnover equipment. The tipping device may rotate the leaf spring 180 ° with the leaf spring bolt facing up. The tightening equipment is connected with the cantilever crane through the pneumatic suspension device to form the whole equipment. The main body of the pneumatic suspension device part and the following screw-down machine part can move in the track of the cantilever crane. The tightening shaft is composed of a motor, a planetary gear reducer and a torque sensor. The tightening device also comprises an STC controller which is used for signal input detection, output control and data processing, and is used for detecting the torque borne by the tightening shaft and ensuring the accuracy of the torque.

After the plate spring is placed on the overturning platform to be fixed, the overturning platform is driven to rotate 180 degrees through the alternating current motor, the plate spring bolt is enabled to face upwards, the moving and tightening equipment is aligned to the plate spring bolt, the starting button is pressed down, the tightening equipment starts to tighten the bolt until the tightening torque is reached, the qualified lamp is displayed to be qualified, the air cylinder automatically rises to drive the equipment to leave a workpiece, an operator can leave along the rail pulling equipment, and one-time tightening work is completed.

The utility model has the advantages of it is following:

the product has high automation degree, simple and convenient operation and high efficiency, and is suitable for large-scale flow production of assembly lines; by using the product, the inaccuracy of torque in bolt fastening can be thoroughly solved, and the assembly quality of the connecting piece is greatly improved; the labor intensity of workers is reduced, and the damage of a pneumatic wrench to the hands and elbows of an operator frequently is overcome; the noise is low, the environment is protected, and occupational diseases of the pneumatic wrench to ears of operators are avoided; the device is fast in adjustment and accurate in positioning, and meets the production beat; the equipment can adapt to various production.
