[0002] In the processing of mechanical parts, grinding, polishing and deburring are necessary steps in wheel hub processing. After the wheel hub processing is completed, some specific positions such as its surface need to be polished to facilitate the use of the next process. Due to the structural characteristics of the wheel hub, it is relatively cumbersome to align and clamp it on the feed roller line. The existing fixing structure is relatively complex and easily damages the surface of the wheel hub. Similarly, the existing fixing structure cannot complete the rotation action while clamping and fixing. Therefore, there is an urgent need to provide a wheel hub positioning and clamping tool. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a wheel hub positioning and clamping tool, which can not only clamp and rotate the wheel hub, but also does not affect the normal transportation of the wheel hub.

[0005] When the clamping device abuts against the upper end of the feed roller line, the hub can move along the length direction of the feed roller line;

[0006] When the clamping device is located at the upper end of the feed roller line, the clamping device clamps and fixes the hub and can rotate along the axial direction of the hub.

[0007] Furthermore, the clamping device includes a concave supporting base, in which two groups of linear translation modules are symmetrically arranged. The upper end of the linear translation module is provided with a clamping assembly used in conjunction with the wheel hub. The clamping assemblies move closer to or farther away from each other to center and fix the wheel hub on the feed roller line.

[0008] Furthermore, the clamping assembly includes a base plate connected to the linear translation module, an arc plate fixed to the base plate through a vertical plate, and an L-shaped plate arranged at the bottom of the arc plate, and a flexible positioning column is provided between the L-shaped plate and the arc plate for use with the wheel hub.

[0009] Furthermore, the length of the arc-shaped plate is greater than the length of the bottom plate.

[0029] like Figures 1-4 As shown, the present invention specifically relates to a wheel hub 100 positioning and clamping tool, comprising a feed roller line 210 and a clamping device 220, wherein the clamping device 220 is disposed on the feed roller line 210 via a lifting device 230, and the clamping device 220 has the following two states relative to the feed roller line 210;

[0030] When the clamping device 220 abuts against the upper end of the feed roller line 210 , the hub 100 can move along the length direction of the feed roller line 210 ;

[0031] When the clamping device 220 is located at the upper end of the feeding roller line 210 , the clamping device 220 clamps and fixes the hub 100 and can rotate along the axial direction of the hub 100 .

[0032] It should be noted that after the hub 100 is processed, all specific positions such as its surface need to be polished to facilitate use in the next process. Due to the structural characteristics of the hub 100, it is relatively cumbersome to center and clamp it on the feed roller line 210.

[0033] The present application provides a clamping device 220 for fixing the wheel hub 100 on the feeding roller line 210, and the clamping device 220 is provided on the feeding roller line 210 by a lifting device 230. Under normal circumstances, the lifting device 230 drives the clamping device 220 to abut against the upper end surface of the feeding roller line 210, so as to facilitate the passage of the wheel hub 100. When the wheel hub 100 needs to be clamped and fixed, the wheel hub 100 is transported to the position of the clamping device 220 through the feeding roller line 210 and stops moving. The stopped wheel hub 100 is centered and positioned by the clamping device 220, and the lifting device 230 simultaneously drives the clamping device 220 to move vertically upward to separate the wheel hub 100 from the feeding roller line 210.

[0034] Furthermore, the lifting device 230 can drive the clamping device 220 to rotate along the axial direction of the wheel hub 100 so as to adjust the position of the valve core on the upper end surface of the wheel hub 100 .

[0035] The clamping device 220 includes a concave supporting base 221, and two groups of linear translation modules 222 are symmetrically arranged in the concave supporting base 221. The upper end of the linear translation module 222 is provided with a clamping assembly 223 used in conjunction with the wheel hub 100. The clamping assemblies 223 move closer to or farther away from each other to align and fix the wheel hub 100 on the feed roller line 210.

[0036] The two clamping assemblies 223 move closer to or farther from each other through the linear translation module 222. When the two clamping assemblies 223 move away from each other, the wheel hub 100 can pass through. When the two clamping assemblies 223 move closer to each other, the wheel hub 100 between the two clamping assemblies 223 can be fixed.

[0037] In addition, the concave bearing base 221 plays a role in supporting the bottom of the hub 100, and at the same time, the two clamping components 223 further support the opposite sides of the hub 100 to ensure stability during the clamping process.

[0038] The clamping assembly 223 includes a base plate 2231 connected to the linear translation module 222, an arc-shaped plate 2233 fixed to the base plate 2231 through a vertical plate 2232, and an L-shaped plate 2234 arranged at the bottom of the arc-shaped plate 2233. A flexible positioning column 2235 is provided between the L-shaped plate 2234 and the arc-shaped plate 2233 for use with the wheel hub 100.

[0039] The L-shaped plate 2234 supports the bottom of the wheel hub 100 , and the flexible positioning column 2235 provided on the L-shaped plate 2234 abuts against the wheel hub 100 to fix the wheel hub 100 and avoid damage to the surface of the wheel hub 100 .

[0040] The length of the arc plate 2233 is greater than that of the bottom plate 2231, which not only better supports the wheel hub 100, but also due to the setting of the vertical plate 2232, when the clamping device 220 moves downward, the bottom of the arc plate 2233 fits with the surface of the incoming roller line without causing interference.

[0041] The concave supporting base 221 can move linearly up and down between the two rollers of the feeding roller line 210, so as to facilitate the storage of the clamping device 220 and avoid interference with the movement of the rollers.

[0042] The lifting device 230 includes a support plate 231 fixed to the feed roller line 210, a connecting plate 233 provided at the bottom of the support plate 231, and a plurality of sliding rods 232 provided between the support plate 231 and the connecting plate 233. The sliding rods 232 are slidably connected to a carrying plate 234 provided with a driving motor 236. The output end of the driving motor 236 is connected to the bottom of the clamping device 220 via a connecting rod 237.

[0043] The support plate 231 is provided with a lifting cylinder 235 that drives the supporting plate 234 to move along the height direction of the sliding rod 232.

[0044] The drive motor 236 is fixed to the support plate 234 and can drive the clamping device 220 to rotate. The lifting cylinder 235 can drive the support plate 234 to move linearly along the height direction of the slide bar 232, thereby synchronously driving the clamping device 220 to move up and down. This arrangement completes the clamping, vertical movement, and rotation of the wheel hub 100.

[0045] The support plate 231 defines an opening for the connecting rod 237 to pass through.

[0046] A visual height measurement sensor 250 is provided on one side of the clamping device 220 to detect the height of the wheel hub 100 .

[0047] A visual inspection system 260 is provided directly above the clamping device 220 , and the position of the valve core of the wheel hub 100 is detected by the visual inspection system 260 , and the position of the valve core is adjusted by rotating the clamping device 220 .

[0048] One side of the feed roller line 210 is provided with a valve hole outer side grinding mechanism 240 used in conjunction with the clamping device 220. When the position of the wheel hub 100 is adjusted, the valve core position of the wheel hub 100 is ground by the valve hole outer side grinding mechanism 240.

[0049] The valve hole outer side grinding mechanism 240 includes a driving cylinder fixed to the feed roller line 210, a valve hole grinding cylinder connected to the telescopic end of the driving cylinder, and a valve core grinding head provided at the output end of the valve hole grinding cylinder.

[0050] The driving cylinder, the valve hole grinding cylinder and the valve core grinding head cooperate with each other to polish and grind the valve core position on the surface of the wheel hub 100.
