[0035] The vertical plate slider 1-6 is installed on the linear rail 5 and can slide along the linear rail 5; the connecting plate positioning slide 1-5 is installed on the vertical plate slider 1-6, and the vertical plate 1-1 is vertically installed on the connecting plate positioning slide 1-5 through the flat key 1-12; the guide rail 1-11 is set on one side of the vertical plate 1-1, and the shaft head slider 1-9 is installed on the guide rail 1-11 through the shaft head slider mounting block 1-3, and the shaft head slider 1-9 can move along the guide rail 1-11; the connecting plate positioning plate 1-7 is installed through the internal thread The cylindrical pin 1-10 is fixedly mounted on the slider mounting transition plate 1-4; the connecting disk locking seat 1-2 is mounted on the shaft head slider mounting block 1-3, and the locking pad 1-8 contacts the guide rail 1-11 and the connecting disk locking seat 1-2 respectively. The connecting disk locking seat 1-2 limits the up and down movement of the shaft head slider mounting block 1-3 through the locking pad 1-8, thereby limiting the up and down movement of the shaft head slider 1-9; the locking pad 1-8 is fixed to the guide rail 1-11 through the connecting disk locking seat 1-2.

[0036] like Figure 10 and Figure 11 As shown, the main reduction angle positioning and centering assembly 3 includes a leveling angle plate 3-1, a centering block 3-2, a centering slide plate 3-3, a guide rail slider assembly 3-4, a leveling mounting base plate 3-5, a leveling spring 3-6, a mounting plate 3-7, a locking nut 3-8 and an adjusting rod 3-9.

[0037] The angle-leveling plate 3-1 is vertically mounted on the centering slide 3-3, with the centering block 3-2 positioned in the upper center of the angle-leveling plate 3-1. The centering slide 3-3 is screwed to the guide rail slider assembly 3-4, which is mounted on the guide rails on the leveling mounting base 3-5. A leveling spring 3-6 is mounted on one side of the centering slide 3-3 and is mounted on an adjustment rod 3-9. The adjustment rod 3-9 is mounted on the mounting plate 3-7 and secured with a lock nut 3-8.

[0039] The V-shaped vertical plate 4-4 and cylinder mounting base 4-7 are mounted on the support slide 4-5, which is then mounted on the guide rail via the slider mounting block 4-8. A high-pressure clamping cylinder 4-6 is mounted on the cylinder mounting base 4-7, one end of which is connected to the cylinder clamping arm 4-1. The end of the cylinder clamping arm 4-1 is connected to the clamping block 4-2, which is driven by the high-pressure clamping cylinder 4-6 to clamp the workpiece (axle tube). An axle tube support pad 4-3 is provided on the V-grooved surface of the V-shaped vertical plate 4-4 to support the axle tube. One side of the slider mounting block 4-8 ​​is connected to the axle housing support locking base 4-10 via a locking block mounting transition plate 4-9. The axle housing support locking base 4-10 is used to lock and prevent the entire axle housing support and clamping assembly 4 from moving.

[0040] When in use, first place the connecting plates at both ends of the axle housing assembly on the flange positioning plate 1-7, then rotate the connecting plate, align the process holes on the connecting plate with the positioning holes on the flange positioning plate 1-7, and use the positioning pins to position the connecting plate and tighten it on the flange positioning plate 1-7; then hang the axle housing on the tool, and the main reduction surface of the axle housing sticks to the smoothing angle plate 3-1, and the axle housing is seated on the V-shaped vertical plate 4-4 of the axle housing support and clamping component 4 by gravity, and then manually move the axle housing left and right to make the main reduction angle positioning and the centering block 3-2 of the centering component 3 contact the hole wall of the axle housing reinforcement ring, and then pull Actuating the pneumatic valve causes the axle housing clamping module 4's clamping cylinder 4-6 to press the axle housing against the V-shaped vertical plate 4-4. The coaxiality between the connecting plate and the axle housing rounded end is then manually adjusted. The connecting plate positioning plate 1-7 can be adjusted in height as needed, and the front-to-back centering can be adjusted using the vertical plate 1-1. Manual adjustment ensures that the connecting plate and the axle housing are concentric. It is important to note that only the first piece requires manual adjustment; subsequent production runs do not require further adjustment. The coaxiality between the connecting plate and the axle housing rounded end is adjusted using the above method at both ends to ensure consistency and stability in subsequent batch production. After adjustments are completed at both ends, the connecting plate positioning clamp assembly is pushed toward the axle housing end until a gap of 3.5-4mm is achieved between the connecting plate and the heel of the axle housing rounded end. At this point, the connecting plate and axle housing can be aligned. The same method is used to align the connecting plate and axle housing at the other end.
