Description

Technical Field

[0001] This utility model belongs to the field of non-destructive testing of wheel hubs, specifically relating to a clamping chuck for wheel hub X-ray inspection equipment. Background Technology

[0002] Cast aluminum alloys are crucial materials for producing blanks for various complex-shaped parts. However, during the casting process, hidden defects such as porosity, inclusions, and cracks inevitably occur inside the wheel. These defects may be difficult to observe directly from specific angles of the wheel. To ensure product quality meets safety standards, comprehensive X-ray non-destructive testing of the wheel is necessary. Given the complexity of the wheel structure (such as spokes and rims), and to improve testing efficiency and ensure X-ray coverage of all areas of the wheel in a short time, the wheel must be precisely rotated during the testing process. This rotational testing method effectively avoids blind spots, ensuring that internal defects are fully exposed and identified, thereby significantly improving product reliability and safety. Therefore, there is an urgent need to develop a dedicated device capable of reliably driving the wheel to rotate during X-ray testing. Utility Model Content

[0003] This invention proposes a clamping chuck for a wheel hub X-ray inspection device to solve the problem in the prior art of lacking a device that can reliably drive the wheel to rotate during X-ray inspection.

[0007] The top cover, gear plate, and conical base are fixed by the first set of positioning holes, the second set of positioning holes, and the third set of positioning holes. The drive shaft passes through the first center hole, the second center hole, and the third center hole, and the top cover is locked by the top screw.

[0008] Preferably, keyways are formed on the inner walls of the second and third center holes and the corresponding shaft segments of the drive shaft, forming a circumferential rigid connection through keyway engagement.

[0015] This utility model proposes a clamping chuck for a wheel hub X-ray inspection device. The top cover, toothed disc, and conical base are respectively provided with coaxially aligned center holes and circumferentially distributed positioning hole groups.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0023] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention.

[0024] Please see Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a clamping chuck for a wheel hub X-ray inspection device, including a top cover 1, a middle toothed disc 2, a bottom conical base 3, and a drive shaft 4.

[0025] The top cover 1 has a first central hole 101 at its center and a first set of positioning holes 102 evenly distributed around its circumference; the toothed plate 2 has a second central hole 201 at its center and a second set of positioning holes 202 evenly distributed around its circumference; the conical base has a third central hole 301 at its center and a third set of positioning holes 302 evenly distributed around its circumference.

[0026] The first central hole 101, the second central hole 201, and the third central hole 301 are coaxially aligned; the positions of the first set of positioning holes 102, the second set of positioning holes 202, and the third set of positioning holes 302 are corresponding; the third set of positioning holes 302 of the conical base 3 is a threaded hole; by passing the positioning pin or positioning screw through the first set of positioning holes 102 of the top cover 1 and the second set of positioning holes 202 of the toothed plate 2 and screwing it into the threaded hole, circumferential rigid locking between the three parts is achieved, and relative rotation is completely eliminated.

[0027] The top cover 1, the toothed plate 2, and the conical base 3 are coaxially mounted on the drive shaft 4. The drive shaft 4 passes through the first central hole 101, the second central hole 201, and the third central hole 301, and is axially fixed by locking the top cover 1 with a top screw. At the same time, keyways are opened on the inner walls of the second central hole 201 and the corresponding shaft segments of the drive shaft 4, and a circumferential rigid connection is formed by key engagement to ensure that the drive shaft 4 drives the three to rotate synchronously and eliminates relative rotation.

[0028] The top cover 1 is made of aluminum alloy to achieve lightweighting; the crankset 2 and the conical base 3 are made of 45 steel and have undergone high-frequency quenching treatment, and weight reduction holes 203 are respectively provided on the crankset and 303 on the conical base. Figure 5As shown, the drive shaft 4 is made of alloy steel with a quenching and tempering treatment, and the shaft end is machined with a keyway 401 and a threaded hole 402. This significantly reduces the moment of inertia while ensuring wear resistance and impact resistance.

[0029] The top cover 1 is disc-shaped and located above the crank 2. The diameter of the top cover 1 is smaller than the outermost diameter of the crank 2. It is fixedly installed on the upper end of the drive shaft by screws passing through the first central hole 101, and is used to axially limit the crank 2. The upper surface of the crank 2 is provided with a ring of crank 2 conical teeth 204 for clamping the wheel hub bead seat. The outer contour of the conical base 3 is a conical surface with a smaller upper part and a larger lower part. It is set as a conical base conical teeth 304. The lower part of the crank 2 and the upper surface of the conical base 3 together define an annular groove. The lower rim of the wheel hub is inserted into the groove. At the same time, the crank 2 conical teeth 204 on the upper part of the crank 2 press against the wheel hub bead seat, which can avoid clamping inaccuracy caused by flash interference.

[0030] The drive shaft 4 is connected to an external rotary drive assembly, which drives the hub chuck to rotate synchronously and drives the hub to rotate through the bevel teeth 204 of the chuck 2. The chuck completely eliminates the jumping and deflection caused by the deformation of the flash by transferring the clamping point from the lower rim flash of the hub to the rigid area above the inner lip, which significantly reduces the impact loss of the equipment and the intensity of manual intervention.

[0031] In one specific embodiment, the upper surface of the toothed plate 2 is provided with a ring of toothed plate conical teeth 204, and six toothed plate weight reduction holes 203 are provided in the circumferential direction.

[0032] In one specific embodiment, the outer contour of the conical base 3 is a conical surface that is smaller at the top and larger at the bottom; the conical surface can be configured as a conical tooth 304 of the conical base, and eight conical base weight reduction holes 303 are provided in the circumferential direction.

[0033] This embodiment discloses a clamping chuck for a wheel hub X-ray inspection device. Through a three-layer stepped structure of top cover-tooth plate-conical base, a co-clamping mechanism of concave annular groove and conical teeth is formed, which completely avoids interference from the flash on the lower rim of the wheel hub. Combined with the triple anti-rotation design of key pins and the main body reinforced with 45# steel, the wheel hub achieves self-rotation without jumping, realizes X-ray scanning without blind spots, and improves the defect detection rate of X-ray inspection equipment.

[0034] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model.
