[0014] like Figure 1 , 2 As shown, a differential shell vertical clamping device for positioning the end face of a half-shaft wheel consists of a base assembly 1, a positioning device 5, a clamping assembly 11, and a side positioning assembly 14.

[0015] The base assembly 1 is composed of a base plate 2, a vertical plate 3, and an upper support plate 4 fixedly connected together; the vertical plate 3 is fixed on the base plate 2, the upper support plate 4 is fixed on the vertical plate 3, and the upper support plate 4 is provided with pin holes.

[0016] The positioning device 5 consists of a positioning mandrel 8, a third nut 19, a support block 6, and a first screw 7. The support block 6 is fixed to the base assembly 1 by the first screw 7. After the positioning mandrel 8 is clearance-fitted with the pin hole of the upper support plate 4, it is fixed to the base assembly 1 by the pin hole and the third nut 19. The positioning mandrel 8 is provided with a threaded hole. The double-ended bolt 10 of the clamping assembly 11 is threadedly connected to the positioning mandrel 8. The positioning device 5 supports the end face of the differential housing half-shaft wheel by the support block 6. The positioning mandrel 8 is clearance-fitted with the inner hole of the differential housing half-shaft wheel to position the radial center of the differential housing.

[0017] The side positioning assembly 14 consists of a side positioning seat 16, a second screw 15, and a pin 17. The side positioning seat 16 is fixed to the base assembly 1 by a third screw 18. The side positioning seat 16 is provided with a pin hole, and the pin 17 is clearance-fitted with the pin hole on the side positioning seat 16. The V-shaped opening of the pin 17 is inserted into the petal shape of the differential shell to position the circumferential center of the differential shell. The side positioning seat 16 is threadedly connected to the second screw 15.

[0018] The clamping assembly 11 consists of a first nut 9, a double-ended bolt 10, a second nut 12, and an open washer 13. One end of the double-ended bolt 10 is threadedly connected to the positioning device 5. The first nut 9 fixes the double-ended bolt 10 to the positioning device 5.

[0019] This utility model discloses a vertical clamping device for positioning the end face of a half-shaft wheel. After installation, the specific operation is as follows: The un-drilled half-shaft wheel is hoisted onto the device. A double-ended bolt is inserted into the inner hole of the small end. A support block supports the end face of the half-shaft wheel. The half-shaft wheel is rotated circumferentially. The pin of the side positioning assembly is inserted into the V-shaped opening at the petal-shaped part of the half-shaft wheel. The second screw locks the pin, thus fixing the half-shaft wheel circumferentially. After the above operation, an open pad is placed on the upper surface of the small end of the half-shaft wheel, and the second nut is tightened, thus fixing the half-shaft wheel. After the above operation, the equipment is started, and the cutting tool completes the drilling of the half-shaft wheel according to the program requirements. After machining, the second nut is loosened, the open pad is removed, the second screw on the side positioning assembly is loosened, and the pin is pulled outwards to the outside of the half-shaft wheel, lifting the half-shaft wheel away. This completes the drilling of one half-shaft wheel. The next workpiece is then installed, and the above cycle is repeated. The length of the double-ended bolt of the clamping device can be adjusted according to the height of the half-shaft wheel. Different types of half-shaft wheels can be machined simply by making different structures of pins according to the different shapes of the half-shaft wheels.
