Abstract

Provided is a fixture for automatic assembly, overturning and welding of sidewall aluminum profile of a rail vehicle, comprising a lifting mechanism, a supporting overturning device mounted on the lifting mechanism, an automatic assembling sidewall profile device mounted on the supporting overturning device, and a self-positioning locking device. The automatic assembling sidewall profile device comprises a sidewall-shaped support steel beam, and a rodless cylinder track platform and a fixing seat. The self-positioning locking devices are mounted on the rodless cylinder track platform and the fixing seat, and have a self-positioning base and a locking device. The self-positioning base comprises an outer housing is provided with the locking device and two symmetrically set self-positioning supports, and faces of the two self-positioning supports matching with the rail vehicle aluminum profile are provided with rollers having a V-shaped gap formed therebetween.

First claim

The invention claimed is:

1. A fixture for automatic assembly, overturning and welding of a sidewall aluminum profile of a rail vehicle, comprising a lifting mechanism, a supporting overturning device, an automatic assembling sidewall profile device and a self-positioning locking device;
the supporting overturning device is mounted on the lifting mechanism; the automatic assembling sidewall profile device is mounted on the supporting overturning device, and the automatic assembling sidewall profile device comprises a sidewall-shaped support steel beam and a rodless cylinder track platform and a fixing seat mounted on a top end of the sidewall-shaped support steel beam; the rodless cylinder track platform and fixing seat are mounted by the self-positioning locking device;
the self-positioning locking device comprises a self-positioning base and a locking device, the self-positioning base comprises an outer housing, two symmetrically set self-positioning supports are provided in the outer housing, and rollers are provided on faces of the two self-positioning supports which match with the sidewall aluminum profile of the rail vehicle and a V-shaped gap is formed between the rollers of the two self-positioning supports; the locking device is provided on a first side of the outer housing.

2. The fixture according to claim 1 , wherein the locking device is a locking cylinder; and a hole is provided on the first side of the outer housing for a piston rod of the locking cylinder to pass through.

3. The fixture according to claim 1 , wherein the lifting mechanism comprises a first lifting mechanism and a second lifting mechanism that is structurally the same as the first lifting mechanism, and both ends of the supporting overturning device are fixed to the first lifting mechanism and the second lifting mechanism respectively.

4. The fixture according to claim 3 , wherein the first lifting mechanism and the second lifting mechanism are sprocket chain lifting mechanisms.

5. The fixture according to claim 3 , wherein the supporting overturning device comprises a first supporting overturning mechanism and a second supporting overturning mechanism that is structurally the same as the first supporting overturning mechanism, the first supporting overturning mechanism is mounted on the first lifting mechanism, and the second supporting overturning mechanism is mounted on the second lifting mechanism.

6. The fixture according to claim 5 , wherein the first supporting overturning mechanism and the second supporting overturning mechanism respectively comprises a motor, the motor is connected to a coupling, the coupling driving a shaft to rotate, the shaft driving a sun gear to rotate; a large gear ring is stationary, planetary gears mounted between the large gear ring and the sun gear and moving in a circular motion around the sun gear, the planetary gears being set 120° apart from each other along a circumferential direction, a turntable is connected to the planetary gears, and a supporting overturning connector is fixedly connected to the turntable to realize the rotation of the supporting overturning connector.

7. The fixture according to claim 1 , wherein a design of the sidewall-shaped support steel beam is determined by a cross-section of the automatic assembly sidewall profile device mounted with the self-positioning locking device.

8. The fixture according to claim 1 , wherein a working surface of each one of the two self-positioning supports is a curved surface; roller pin holes are provided on the working surfaces of the two self-positioning supports, and the roller pin hole is connected with a roller by a pin, an axis line of the roller is a horizontal line.
