Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, specifically to a wheel hub clamping mechanism and a wheel hub polishing machine. Background Technology

[0002] After the wheel hub is manufactured, it needs to undergo a series of polishing processes. In the wheel hub polishing process, the clamping of the wheel hub is a particularly important step. The quality of the clamping directly affects the quality, efficiency and safety of the polishing operation. Existing wheel hub clamps usually use three-jaw clamps to clamp the wheel hub directly. Clamps without additional protection can easily damage the outer surface of the wheel hub. In addition, traditional clamps rely on forced centering for positioning and clamping. After the wheel hub is subjected to force for a long time during polishing, local uneven force can easily cause deformation, affecting the quality of the wheel hub product. Utility Model Content

[0033] Example 1

[0034] Please refer to Figures 1-5 As shown, this embodiment provides a wheel hub clamping mechanism 400, including: a support plate 410, a positioning component 440 installed in the middle of the support plate 410, and a plurality of clamping structures 420 and support seats 430 installed on the support plate 410. The plurality of clamping structures 420 and support seats 430 are disposed on the support plate 410. The positioning component 440 is used for wheel hub installation and positioning. The output end of the clamping structure 420 is provided with a shaped pad 424 that contacts the wheel hub. The plurality of circumferentially arranged shaped pads 424 limit the wheel hub. The clamping structure 420 and the support seat 430 cooperate to clamp and fix the wheel hub. The wheel hub is first positioned and placed in the wheel hub clamping mechanism 400 by the positioning component 440. When the wheel hub is positioned and placed, the plurality of support seats 430 provide support for the lower part of the wheel hub. Then, the plurality of circumferentially distributed clamping structures 420 clamp and fix the wheel hub.

[0035] As attached Figure 5 As shown, the clamping structure 420 further includes a fixing plate 421 mounted on the support plate 410. A clamping cylinder 422 is mounted on the side of the fixing plate 421. A clamping block 423 is provided at one end of the push rod of the clamping cylinder 422. An irregularly shaped pad 424 is embedded inside the clamping block 423. The side of the fixing plate 421 is provided with a first adjustment hole 425 for mounting the clamping cylinder 422. The first adjustment hole 425 allows the clamping cylinder 422 to be vertically adjusted, enabling fine-tuning during wheel hub clamping. To meet different clamping height requirements, the bottom of the fixing plate 421 is provided with a second adjustment hole 426. The fixing plate 421 is mounted on the support plate 410 through the second adjustment hole 426. The fixing plate 421 can be finely adjusted through the second adjustment hole 426, so that the clamping structure 420 can be finely adjusted during the wheel hub clamping operation to meet the requirements of fine-tuning clamping force. Several clamping structures 420 cooperate to form a circumferential clamping fixture for the wheel hub, which can evenly clamp the wheel hub and ensure the stability of the wheel hub during the processing.

[0036] Furthermore, the irregularly shaped pad 424 is made of flexible material and has a corner shape. The corner of the irregularly shaped pad 424 contacts the bottom edge of the wheel hub. The clamping cylinder pushes the irregularly shaped pad 424 to move horizontally. After being pushed, the irregularly shaped pad 424 will contact the edge of the wheel hub, thereby generating a centripetal and downward clamping force on the wheel hub and firmly pressing the wheel hub onto the support seat 430. The irregularly shaped pad 424 made of flexible material prevents damage to the outer surface of the wheel hub when it contacts the wheel hub.

[0037] As attached Figure 2 As shown, further, several clamping structures 420 and support bases 430 are arranged circumferentially on the support plate 410. Each clamping structure 420 achieves uniform clamping of the wheel hub through synchronous drive, ensuring balanced distribution of clamping force, avoiding wheel hub deformation or positioning deviation due to uneven force, and improving clamping stability and processing accuracy.

[0038] As attached Figure 4 As shown, the support plate 410 further includes several circumferentially distributed first mounting grooves 411 and second mounting grooves 412, spaced apart. Positioning holes 413 are provided on both sides of the first mounting grooves 411 and 412. The clamping structure 420 is installed in the first mounting groove 411 through the positioning holes 413, and the support base 430 is installed in the second positioning groove 412 through the positioning holes 413. Both the first mounting grooves 411 and 412 have guide grooves for placing the clamping structure 420 and the support base 430. The first mounting grooves 411 and 412 can assist the clamping structure 420 and the support base 430 in installation and positioning. The clamping mechanism 400 and the support base 430 can move linearly towards the center of the support plate 410. A positioning groove 415 is provided in the middle of the support plate 410 for positioning the positioning component 440. The positioning groove 415 allows the positioning plate 441 to be positioned and installed.

[0039] Furthermore, the first mounting groove 411 is provided with a clearance opening 414 in the middle, which provides sufficient room for the gripper to move and facilitates the replacement of different grippers.

[0040] As attached Figure 3 As shown, the positioning component 440 further includes a support plate 444, an intermediate plate 443, a pad plate 442, and a positioning plate 441 arranged sequentially from top to bottom. The positioning plate 441 is installed in the positioning groove 415 of the support plate 410. The outer diameters of the support plate 444, the intermediate plate 443, and the pad plate 442 are the same. The detachable positioning component 440 can be replaced according to clamping requirements to match different wheel hubs. The hollow wheel hub can be installed and positioned by the positioning component 440, and the wheel hub with a bottom edge can be supported in the middle by the positioning component 440.

[0041] Furthermore, the support base 430 has an arc-shaped support surface on its inner side that matches the outer contour of the wheel hub. The support base 430 also has a positioning step 431. The support base 430 with the arc-shaped support surface can cooperate with the bottom of the wheel hub when facing special wheel hub types. The positioning step 431 can assist in the placement of special wheel hubs to ensure the stability of special wheel hubs after clamping.

[0042] Furthermore, the bottom of the support plate 410 is also provided with a connector 450, and the support plate 444 is installed together with the rotary table 300 through the connector 450.

[0043] Example 2

[0044] like Figure 1 As shown, this utility model also provides a wheel hub polishing machine, which includes a wheel hub clamping mechanism 400 as described in Embodiment 1. The wheel hub clamping mechanism 400 is mounted on a rotary table 300, and the rotating table 310 provided on the rotary table 300 drives the clamping mechanism 400 to rotate.

[0045] The wheel hub is placed in the positioning component of the wheel hub clamping mechanism by a person / mechanical arm / robot. Then, the clamp button is pressed to clamp the wheel hub. The clamping cylinder 422 pushes the irregular pad 424 to contact the outer edge of the wheel hub. The circumferentially set clamping structure 422 will clamp and fix the wheel hub. Then, the wheel hub fixed in the clamping structure 422 will rotate under the drive of the rotating table 310 to facilitate the subsequent polishing work.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
