The rotating motor and the air cylinder are fixed on the shell, and the fixed end of the limiting column is fixed on the shell.

The rotary limiting plate is fixed on the inner wall of the shell, limiting openings are formed in the rotary limiting plate, limiting end faces are arranged on two sides of each limiting opening, and the limiting ends of the limiting columns are located on the rotating paths of the limiting end faces.

The rotating shaft is provided with a cavity for accommodating the spline shaft, and the spline shaft is connected with the inner wall of the cavity in a sliding manner.

The shell is provided with a connecting flange for connecting the industrial robot.

The cylinder is a double-rod cylinder.

The nut accommodating hole is of a regular polygon, and the regular polygon is identical to the nut in appearance.

The beneficial effects of the utility model are as follows: the screw-down sleeve avoids the rear suspension when entering the suspension assembly, stretches out and draws back before screwing down, so that the nut enters a locking hole at the end part of the rotary wrench, the nut is locked and does not rotate any more, the screw-down shaft drives the sleeve to screw down the bolt, and automatic screwing is completed. Replace the manual work to screw up, raise the efficiency, reduce intensity of labour.

Detailed Description

The utility model is further described with reference to fig. 1-5:

the utility model provides a back suspension bolt is equipped with cap and screws up frock, screws up axle 1 and connects drive sleeve 2, and sleeve 2 contralateral is equipped with rotatory spanner 3, and rotatory spanner 3 tip is equipped with nut accommodation hole 4, nut accommodation hole 4 is regular polygon, regular polygon is the same with the nut appearance, and nut accommodation hole 4 tip is equipped with keeps off platform 15, and rotatory spanner 3 passes through rotation axis 5 and connects spline shaft 10, and rotation motor 6 is connected through rotatory limiting plate 11 to spline shaft 10, and rotatory limiting plate 11 lateral part is equipped with spacing post 12, and rotation axis 5 runs through and rotates and connect push-and-pull drive plate 7, push-and-pull drive plate 7 passes through push rod 8 and connects cylinder 9. The cylinder 9 is a double-rod cylinder.

The rotating motor 6 and the air cylinder 9 are both fixed on the shell 13, and the fixed end of the limiting column 12 is fixed on the shell 13. The rotary limiting plate 11 is fixed on the inner wall of the shell 13, a limiting opening is formed in the rotary limiting plate 11, limiting end faces are arranged on two sides of the limiting opening, and the limiting end of the limiting column 12 is located on the rotating path of the limiting end faces.
