[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" etc., which indicate orientation or positional relationship, are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0028] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-7 As shown, this utility model is a fixing fixture for installing a half-shaft sleeve, including a worktable 1. A hydraulic slide table 11 and a heating and shaping device 12 are respectively installed at the front and rear ends of the worktable 1. A first slide rod 13 is installed on the worktable 1. A second push rod 15 is installed at the bottom of the first slide rod 13 through a fixed seat 14. The extended end of the second push rod 15 is connected to a movable base 2 through a fixed block 21. The movable base 2 is slidably engaged with the first slide rod 13. The movable base 2 is installed on the worktable 1. A transmission screw 8 is vertically installed on the movable base 2. Second slide rods 9 are vertically installed at both ends of the transmission screw 8. A lifting plate 3 is threadedly connected to the transmission screw 8 and slidably connected to the second slide rods 9. Utilizing the principle of threaded transmission, the lifting plate 3 can be driven to move up and down along the second slide rods 9, thereby synchronously adjusting the height of the upper clamping plate 5 to adapt to the installation height of half-shaft sleeves of different specifications. A first push rod 7 is installed on the upper part of the lifting plate 3. A positioning assembly is installed between the lifting plate 3 and the movable base 2. The positioning assembly includes an upper clamping plate 4 installed below the lifting plate 3 and a lower clamping plate 5 on the movable base 2. The upper clamping plate 4 and the lower clamping plate 5 are respectively provided with an upper clamping end 41 and a lower clamping end 51. The clamping surfaces of the upper clamping end 41 and the lower clamping end 51 are both arc surfaces, which are adapted to the outer contour of the half-shaft sleeve. Several rollers 6 are installed inside the arc surface. The axis of the rollers 6 is parallel to the axis of the half-shaft sleeve. Figure 6There are no rollers in the center of the arc surface; the rollers are located on both sides of the arc surface. The rollers on both sides can hold the pipe fittings, which is suitable for pipe fittings of various sizes. During use, the rollers 6 can reduce the friction between the sleeve and the clamping surface. This positioning component can support long pipe fittings and prevent the axis from shifting. Furthermore, the chord length of the arc surface of the upper clamping end 41 is greater than the chord length of the arc surface of the lower clamping end 51, so that the upper clamping plate 4 can completely cover the half-shaft sleeve when it moves downward, forming a stable clamping state and further improving the fixing effect. A sliding groove 22 is opened on the movable base 2, and a support bar 52 is provided at the bottom of the lower clamping plate 5. The support bar 52 slides with the sliding groove 22, so that the lower clamping plate 5 can move laterally along the sliding groove 22. At the same time, a threaded hole 53 is provided vertically on the movable base 2, and an elongated hole 54 is opened on the lower clamping plate 5. The lower clamping plate 5 is fixed to the movable base 2 by bolts, which can adjust and fix the lower clamping plate 5 to the movable base 2, so as to adjust the clamping range according to the length of the half-shaft sleeve. The first push rod 7 is connected to the upper clamping plate 4 via a connector. The connector includes a T-shaped connecting shaft 71, on which a double-eared hinge seat 72 is hinged. The double-eared hinge seat 72 is fixed on the upper clamping plate 4. In use, the first push rod 7 extends and retracts, causing the upper clamping plate 4 to lock onto the lower clamping plate 5. The upper clamping plate 4 can rotate around the T-shaped connecting shaft 71 via the double-eared hinge seat 72, so that the clamping force of the upper clamping plate 4 can be evenly transmitted to the roller 6, which is convenient for clamping pipes of different diameters.

[0029] The usage method of this embodiment is as follows:

[0030] refer to Figure 2 The pipe to be heated and shaped is placed on the lower clamping end 51 of the lower clamping plate 5. One end is fixed by the clamp on the hydraulic slide of the clamping fixture on the worktable 1. The first push rod 7 extends downward and the upper clamping plate 4 is clamped on the lower clamping plate 5. As the hydraulic slide of the clamping fixture 11 extends, the second push rod 15 pushes the movable base 2 to extend, which plays the role of supporting the long pipe.

[0031] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to specific implementation methods.
