Technical Field

[0001] This utility model relates to the field of wheel hub clamping technology, and specifically to a wheel hub clamping device used in heat treatment processes. Background Technology

[0002] The heat treatment process for wheel hubs mainly includes quenching, tempering, and aging. Quenching involves rapid cooling after high-temperature heating to improve the hardness and strength of the wheel hub; tempering uses medium-low temperature heating to eliminate internal stress and improve toughness; aging stabilizes material properties. Aluminum alloy wheel hubs also require solution treatment to ensure uniform distribution of alloying elements; after heat treatment, non-destructive testing is necessary to ensure quality meets standards.

[0003] Using clamps to hold wheel hubs during transport is of great significance. Firstly, it ensures safe handling; the clamps can firmly grip the wheel hub, preventing slippage and damage or accidents. Secondly, it improves transport efficiency; specialized clamps allow for rapid loading and unloading, reducing manual operation time. Finally, it protects the wheel hub surface; the clamp contact surfaces are typically designed with cushioning materials to prevent scratching of machined surfaces. Hydraulic or pneumatic clamps can also achieve automated transport and seamless integration with the production line, significantly improving production cycle time and operational safety. The appropriate selection of transport clamps plays a crucial role in ensuring product quality and production efficiency.

[0026] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0027] like Figure 1 and Figure 2 As shown, a wheel hub clamp for heat treatment processes includes a clamping support 1 detachably mounted to the end of an industrial robot. The clamping support 1 includes a clamping flange seat 11 and an extended support seat 12 disposed on one side of the clamping flange seat 11, and the driving element 4 is disposed on one side of the extended support seat 12.

[0028] The clamp flange 11 can be detachably installed at the end of the industrial robot, and the extended support 12 is used to increase the length of the entire clamping support 1 so as to facilitate the subsequent installation of other components.

[0029] Please continue to refer to this. Figure 3 The clamping support 1 has two sets of linkage mechanisms 2 and a sliding drive component 3 on one side. The drive component 3 can drive each linkage mechanism 2 to move during sliding. The extended support base 12 has a support base plate 6 on one side. The surface of the support base plate 6 has several inner side plates 61, and a support top plate 7 is installed on the top of each inner side plate 61. The linkage mechanisms 2, drive components 3, and drive elements 4 are all disposed within the gap between the support base plate 6 and the support top plate 7. The clamping support 1 also has a drive element 4 on one side to push the drive component 3 to slide.

[0030] In this embodiment, the driving element 4 is a driving cylinder, the surface of the supporting base plate 6 is provided with a plurality of slide rails 62 and a slider 63 slidably connected to the surface of the slide rails 62, the driving component 3 is disposed on the surface of the slider 63, and the piston rod of the driving cylinder is connected to the interior of the driving component 3.

[0031] During the extension and retraction of the piston rod of the drive cylinder, the drive component 3 can change its position. During the position change of the drive component 3, the slider 63 at the bottom of the drive component 3 slides relative to the surface of the slide rail 62.

[0032] The driving component 3 includes a connector 31 disposed on the surface of the slider 63 and a cylinder connector 32 disposed inside the connector 31. The connector 31 has first hinge holes 311 on both sides, and the end of each linkage mechanism 2 is hinged to the inside of the first hinge holes 311.

[0033] The connector 31 transmits the force of the driving cylinder piston to the connector 31, and the slider 63 at the bottom of the connector 31 slides relative to the surface of the slide rail 62. During the sliding process, the position of the first hinge hole 311 also changes, and the thrust generated by the first hinge hole 311 causes the end of the linkage mechanism 2 to rotate.

[0034] Please continue to refer to this. Figure 3 The linkage mechanism 2 includes a supporting link 21 and a supporting claw arm 22. One end of the supporting link 21 is hinged to the inside of a first hinge hole 311. One end of the supporting claw arm 22 is provided with a second hinge hole 221. The other end of the supporting link 21 is hinged to the inside of the second hinge hole 221 of the supporting claw arm 22. The clamping element 5 is disposed at the other end of the supporting claw arm 22. The end of the supporting link 21 is locked to the inside of the first hinge hole 311 by a first shoulder hinge pin 23, and the end of the supporting link 21 is locked to the inside of the second hinge hole 221 by a second shoulder hinge pin 24. The supporting claw arm 22 is also provided with a third hinge hole 222. The shoulder bolt 25 provided at the end of the supporting base plate 6 is connected to the inside of the third hinge hole 222.

[0035] The clamping element 5 is composed of several anti-slip clips 51 stacked together. Each anti-slip clip 51 has a locking through hole 511 in the middle. The anti-slip clip 51 is connected to the end of the support claw arm 22 through the locking through hole 511.

[0036] During the change of position of the first hinge hole 311, one end of the support rod 21 rotates inside the first hinge hole 311, and the other end of the support rod 21 rotates inside the second hinge hole 221. At this time, the third hinge hole 222 of the support claw arm 22 also rotates relative to the shoulder bolt 25.

[0037] During these articulated linkage processes, the angle between the end sidewall of the support claw arm 22 and the sidewall of the support link 21 changes. The support link 21 can then drive the support claw arm 22 to change its angle relative to the support base plate 6, ultimately achieving the clamping and releasing of the anti-slip clip 51 on the wheel hub sidewall.

[0038] Please continue to refer to this. Figure 4 and Figure 5 The extended support base 12 is also provided with a camera welding base 8 on its top. The camera welding base 8 is provided with a camera placement frame 81 on its top. The camera placement frame 81 is provided with an industrial camera 82 for detecting the position of materials and a light source 83 inside. The support top plate 7 is also provided with a number of photoelectric mounting bases 9 on the side near the support bottom plate 6. Each photoelectric mounting base 9 is provided with a laser displacement sensor 91 for detecting whether it is clamped in place inside.

[0039] Since the industrial robot can move the entire wheel hub fixture to change position, but since the position of each wheel hub is not the same, when clamping different wheel hubs, the industrial camera 82 takes pictures of the wheel hubs, uses image processing algorithms to analyze the image content, identifies the characteristics of the wheel hubs, calculates the position and orientation of the wheel hubs relative to the camera (and thus relative to the robot fixture), and finally adjusts the orientation of the industrial robot. During this judgment process, the light source 83 provides supplementary lighting.

[0040] After the industrial robot's posture is adjusted, the anti-slip clamp 51 at the end of the linkage mechanism 2 clamps the side wall of the wheel hub. After clamping, the laser displacement sensor 91 emits a laser beam and receives the reflected light signal to accurately measure the relative position (such as distance and angular offset) between the wheel hub and the clamp, with an accuracy of up to the micrometer level, ensuring precise positioning of the clamp.

[0041] Working principle and usage of this utility model:

[0042] When clamping the wheel hub, the piston rod of the drive cylinder can drive the drive component 3 to change position during the extension and retraction process. The connector 31 transmits the force of the drive cylinder piston to the connector 31, and the slider 63 at the bottom of the connector 31 slides relative to the surface of the slide rail 62. During the sliding process, the position of the first hinge hole 311 also changes.

[0043] During the change of position of the first hinge hole 311, one end of the support rod 21 rotates inside the first hinge hole 311, and the other end of the support rod 21 rotates inside the second hinge hole 221. At this time, the third hinge hole 222 of the support claw arm 22 also rotates relative to the shoulder bolt 25.

[0044] During these articulated linkage processes, the angle between the end sidewall of the support claw arm 22 and the sidewall of the support link 21 changes. The support link 21 can then drive the support claw arm 22 to change its angle relative to the support base plate 6, ultimately achieving the clamping and releasing of the anti-slip clip 51 on the wheel hub sidewall.

[0045] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
