[0025] In order to more clearly illustrate the technical solution of the present invention, the drawings required for use in the description will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without paying creative work.

[0026] Hereinafter, the directions toward the two ends of the main shaft 2 are referred to as the outside, and the direction toward the middle of the main shaft 2 is referred to as the inside.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 Shown:

[0028] A threaded section 10 is provided on the inner wall of the hollow main sleeve 1 , and an axial adjustment strip 11 is protruded from the outer wall of the main sleeve 1 , on which a row of axially arranged adjustment holes 12 are provided.

[0029] The main shaft 2 is provided with a threaded section 20, and the main shaft 2 passes through the main sleeve 1 and the threaded section 20 on the main shaft 2 is meshed with the threaded section 10 on the inner wall of the main sleeve 1. An operating head 21 is provided at the end of the main shaft 2.

[0030] A clamp block 3 has a U-shaped notch 31 on its upper portion, and through holes 32 are respectively provided on the two side walls of the U-shaped notch 31. The U-shaped notch 31 of the clamp block 3 is clamped outside the main sleeve 1, and a pair of bolt and nut assemblies 34 pass through the through holes 32 on the two side walls of the U-shaped notch 31 and an adjustment hole 12 on the adjustment strip 11 to fix the main sleeve 1 and the clamp block 3.

[0031] A protruding clamping block 33 is provided on the outer side wall of the clamping block 3 facing the operating head 21 .

[0032] A positioning block 4 has a slot 41 on its inner side. The slot 41 is larger than the block 33 . The block 33 is loosely inserted into the slot 41 .

[0033] The outer side of the positioning block 4 is provided with a top block 42 made of PU (also known as polyurethane elastomer), and the outer side of the top block 42 is an arc surface. The bolt 43 passes through the through hole on the top block 42 and is screwed into the screw hole on the positioning block 4 to fix the top block 42 on the positioning block 4.

[0034] A support screw 44 is screwed into a screw hole 341 provided on the side wall of the clamping block 3, and the support screw 44 supports the lower surface of the positioning block 4. Since the size of the slot 41 is larger than the above-mentioned block 33, the positioning block 4 is loosely hung on the block 33 of the clamping block 3 by the slot 41. The support screw 44 can provide a certain support for the positioning block 4 when disassembling and moving the entire shaping rod, so that the positioning block 4 will not fall down casually and cause inconvenience in operation.

[0035] A radial through hole 22 is formed at the other end of the main shaft 2 relative to the abutment block 42 .

[0036] A sleeve 51 is connected to the inner side of a shaping splint 5 . A radial through hole 52 is provided on the sleeve 51 . The sleeve 51 is sleeved on the end of the main shaft 2 , that is, the main shaft 2 is inserted into the sleeve 51 .

[0037] The lower part of the clamping block 3 located on the other side of the main shaft 2 relative to the U-shaped notch 32 has an inner side surface 35 facing the shaping clamping plate 5, which is a slope with an angle of 86-88 degrees that is not perpendicular to the bottom surface 36. The slope faces the direction of the main shaft 2, that is, the thickness of the clamping block 3 gradually decreases as it approaches the main shaft 2.

[0038] Relatively speaking, the inner side surface 55 of the above-mentioned inclined surface of the shaping splint 5 facing the clamping block 3 is an inclined surface with an angle of 86-88 degrees that is not perpendicular to the bottom surface 56 and faces the main axis 2, that is, the thickness of the shaping splint 5 gradually decreases toward the main axis 2.

[0039] In this way, the distance between the clamping block 3 and the shaping clamping plate 5 increases toward the main axis 2.

[0040] A shaping block 57 with a transverse clamping groove 58 is fixedly connected to the other side of the shaping clamping plate 5 relative to the sleeve 51. A shaping head 59 is embedded in the transverse clamping groove 58. The outer side of the shaping head 59 is a curved surface. The shaping head 59 is a metal block that can be replaced according to the situation of the wheel hub. The curved surface that matches the circumference arc of different wheel hubs (for example, 15-inch, 16-inch, and 17-inch wheel hubs) can be selected.

[0041] A vertical screw rod 61 is screwed into the screw hole 54 provided on the shaping block 57 , a through hole of a hanging plate 6 is sleeved on the vertical screw rod 61 , and a horizontal fixing bolt 62 is screwed into the screw hole provided on the side wall of the hanging plate 6 and then pressed against the hanging plate 6 .

[0042] like Figure 1 , Figure 3 , Figure 4 As shown:

[0043] The hub 9 is radially out of round at position A.

[0044] Select the shaping head 59 of suitable size to adapt to the A' position of the hub 9, and embed the shaping head 59 into the transverse clamping groove 58 of the shaping block 57. At this time, the shaping clamping plate 5 is sleeved on the end of the main shaft 2 with the sleeve 51, and the shaping clamping plate 5 and the main shaft 2 can rotate relative to each other.

[0045] The clamp block 3 is slid on the main sleeve 1, thereby greatly adjusting the distance between the outer side of the top block 42 and the outer side of the shaping head 59. When it is slightly smaller than the diameter of the upper end of the inner wall of the wheel hub 9, the bolt and nut assembly 34 is passed through the through holes 32 on the two side walls of the U-shaped notch 31 and the corresponding adjustment hole 12 on the adjustment strip 11 to fix the main sleeve 1 and the clamp block 3. In this way, the distance between the outer side of the top block 42 and the outer side of the shaping head 59 can be greatly adjusted in advance for various wheel hubs 9 with different diameters to adapt to the size of the wheel hub 9.

[0046] The push block 42 is pressed against the A' position of the inner ring of the wheel hub 9 relative to the A position, and the shaping head 59 is aligned with the inner ring A position of the wheel hub 9. The main shaft 2 is rotated by means of a lever, pliers, wrench or other tools through the operating head 21. Since the main shaft 2 is connected to the main sleeve 1 by threaded engagement, the entire shaping rod is extended, and the main shaft 2 pushes the shaping splint 5, the shaping block 57 and the shaping head 59 at its end forward. At this time, the wheel hub can also be heated to soften it. The shaping head 59 with an arc surface selected in advance to match the circumferential arc of different wheel hubs (for example, 15, 16, and 17-inch wheel hubs) pushes the inner ring A position of the wheel hub 9 outward to deform it to the repaired position.

[0047] The top block 42 made of PU is placed at the A' position to support and position the wheel hub without causing any hard deformation or damage to the wheel hub. The positioning block 4 is loosely hung on the clamping block 33 of the clamping block 3 by means of the clamping groove 41, so that it can be shaken up and down and adjusted to be adaptively pressed against the A' position.

[0048] like Figure 6 As shown:

[0049] The shaping clamp plate 5 can be replaced by a shaping block 57' with a transverse clamping groove 58' on the outer side and a sleeve 51' on the inner side. A shaping head 59' is embedded in the shaping block 57', and the outer side of the shaping head 59' is an arc surface. The shaping head 59' is a metal block that can be replaced according to the condition of the wheel hub. A vertical screw rod 61 is screwed into the screw hole 54' provided on the shaping block 57', a through hole of a hanging plate 6 is sleeved on the vertical screw rod 61, and a horizontal fixing bolt 62 is screwed into the screw hole provided on the side wall of the hanging plate 6 and then pressed against the hanging plate 6.

[0050] When in use, the sleeve 51 ′ is directly sleeved on the end of the main shaft 2 , that is, the main shaft 2 is inserted into the sleeve 51 ′, and then the device can be used as described above.

[0051] The function of the hanging plate 6 is to be placed on the upper edge of the position A of the wheel hub 9 so that before the shaping rod is extended and the inner wall of the wheel hub 9 is clamped, this end of the shaping block 59 will not fall down casually to cause inconvenience in operation.

[0052] like Figure 2 As shown:

[0053] In the above-mentioned repair of the radial deformation of the wheel hub 9, the shaping splint 5 does not need to be used.

[0054] When the wheel hub 9 is axially deformed, such as the B portion is tilted and deformed, it is necessary to use the shaping splint 5.

[0055] At this time, the inner side surface 35 of the clamp block 3, i.e., the inclined surface facing the shaping clamp plate 5, is placed on the upper edge of the B portion of the hub 9, and the inner side surface 55 of the shaping clamp plate 5, i.e., the inclined surface facing the clamp block 3, is placed against the lower edge B' of the hub 9 opposite to the B portion. A bolt 53 passes through the radial through hole 22 on the main shaft 2 and the radial through hole 52 on the sleeve 51 to fix the shaping clamp plate 5 on the main shaft 2 to prevent the shaping clamp plate 5 from falling off.

[0056] First, slide the clamp block 3 onto the main sleeve 1 to a suitable position and then fix the main sleeve 1 and the clamp block 3 to connect them.

[0057] Then, the main shaft 2 is rotated by the operating head 21, the entire shaping rod is shortened, the clamping block 3 and the shaping clamping plate 5 are brought closer, and the B part of the hub 9 is forced to deform to the repaired position.

[0058] Since the spacing between the clamping block 3 and the shaping clamping plate 5 increases toward the main shaft 2 and is in an eight-shaped shape, when the wheel hub 9 is clamped, it is stuck inside and will not slide out of the space.

[0059] The inner diameter of the sleeve 51 of the shaping splint 5 or the inner diameter of the sleeve 51' of the shaping block 57' is the same as the outer diameter of the main shaft 2. In this way, after the shaping splint 5 or the shaping block 57' is put on the main shaft 2, the force applied during operation will not be radially decomposed due to the difference in diameter between the main shaft 2 and the sleeve 51 or sleeve 51', thereby causing the adverse consequence of deformation of the main shaft 2.
