The control unit separately controls each tightening device to realize the screwing in and screwing out of the screw in the threaded hole.

The tightening device includes a light rod seat, a light rod, a slider, a motor and a connector; the light rod is fixed on the base plate through the light rod seat, and the light rod passes through the slider and is slidably connected with the slider , the motor is fixedly connected to the slider, the output shaft of the motor passes through the slider and is fixedly connected to one end of the connector, and the other end of the connector is in the shape of a hexagonal wrench for fixing and tightening the screws.

The control unit controls the start and stop of the motor, and controls the forward rotation and reverse rotation of the motor.

The key reinforcement device for auxiliary fixing between wheel axles also includes a power supply, the power supply is fixed on the bottom plate, and the power supply is connected to each motor for power supply.

The beneficial effects of the utility model are as follows: before using the key reinforcement device for auxiliary fixing between the wheel shafts, it is first necessary to drill corresponding threaded holes on the wheel and the shaft according to the position of the threaded holes on the bottom plate, and then screw the screws Fix it on the connector, align the reinforcing device with the wheel and the shaft according to the position of the threaded hole, and control the motor to rotate clockwise through the control unit, so that multiple screws on the outer ring are screwed into the wheel, and multiple screws on the inner ring are screwed into the shaft. Thereby the wheel and axle are further connected and fixed. When it needs to be disassembled, control the motor to rotate counterclockwise and unscrew the screw. The utility model can assist the key through the anti-shear strength of the screw and the frictional force generated when tightening, and solves the problem of excessive wear of the key when the stamping equipment is used for a long time.

Detailed ways

Embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

Referring to accompanying drawings 1 and 2, the key reinforcement device for auxiliary fixing between wheel axles of the present invention includes a bottom plate 1, a tightening device and a control unit;

The inner ring of the bottom plate 1 is evenly distributed with a plurality of threaded holes on the circumference relative to the shaft end, that is, at least two; the outer ring of the bottom plate 1 is evenly distributed with a plurality of threaded holes on the circumference relative to the wheel end surface, that is, at least two; The number of multiple threaded holes evenly distributed on the inner and outer circles of the bottom plate 1 is determined according to the actual force requirements;

A tightening device is provided at the corresponding position of each threaded hole on the base plate 1, and a screw is fixed at the lower end of the tightening device, and the screw is matched with the threaded hole;

The control unit separately controls each tightening device to realize the screwing in and screwing out of the screw in the threaded hole.

Described tightening device comprises feed rod seat 2, feed rod 3, slide block 4, motor 5 and connector 6; Described feed rod 3 utilizes screw to be fixed on the described base plate 1 by feed rod seat 2, and described slide block 4 The four corners of each have a through hole respectively, and the said through hole cooperates with the light rod 3 passing through the through hole respectively, and the said light rod 3 is slidably connected with the said slide block 4, and the slide block 4 can move in the stroke of the light rod 3 Free sliding within the range, the motor 5 is fixedly connected to the slider 4 by screws, the output shaft of the motor 5 passes through the center hole of the slider 4 and is welded to one end of the connecting piece 6, and the other end of the connecting piece 6 is Hex wrench shape for fixing and tightening screws.
