[0026] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0027] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, for the purposes of describing the embodiments of the present application herein.

They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present utility model.

[0029] like Figures 1-6As shown, the utility model specifically relates to a wheel hub grinding tool, including a double-sided roller line 310, the double-sided roller line 310 including a roller support 311 and a plurality of rollers 312 provided on the roller support 311; the roller support 311 is fixed with a rotating clamping device 320 via a transverse plate 321, the rotating clamping device 320 includes symmetrically arranged V-shaped roller clamping assemblies 323, the V-shaped roller clamping assemblies 323 are provided with flexible rollers 3235 that abut against the side wall edges of the wheel hub 100, and the wheel hub 100 placed between the two V-shaped roller clamping assemblies 323 is clamped and fixed by the flexible rollers, and the V-shaped roller clamping assemblies 323 are provided with a forward and reverse servo motor 324 that can drive the flexible rollers 3235 to rotate;

[0030] It also includes a wheel hub inner wall grinding device 330 arranged on the roller bracket 311, and the wheel hub inner wall grinding device 330 includes a lateral translation module 331, a lifting cylinder 332 arranged on the lateral translation module 331 and a disc-shaped brush 334 arranged on the lifting cylinder 332. The disc-shaped brush 334 is abutted against the inner wall of the wheel hub 100 through the lateral translation module 331 and the lifting cylinder 332 to complete the grinding of the inner wall of the wheel hub 100.

[0031] It should be noted that the double-sided roller line 310 is used for transporting the wheel hub 100 . When the wheel hub 100 is transported between the two V-shaped wheel hub 100 clamping assemblies, the wheel hub 100 is clamped and fixed by the two V-shaped roller clamping assemblies 323 .

[0032] In addition, the V-shaped roller clamp assembly 323 is provided with a flexible roller 3235. When the wheel hub 100 is located between the two V-shaped roller clamp assemblies 323, the flexible roller 3235 actually abuts against the edge of the side wall of the wheel hub 100 to fix the wheel hub 100, ensuring that the wheel hub 100 does not shift during the grinding process.

[0033] Furthermore, the V-shaped roller clamp assembly 323 is provided with a forward and reverse servo motor 324 that drives the flexible roller 3235 to rotate. The forward and reverse servo motor 324 and the driving wheel 3241 cooperate with each other to drive the flexible roller 3235 to rotate. Since the flexible roller 3235 abuts against the edge of the side wall of the hub 100, the hub 100 rotates synchronously to achieve the purpose of adjusting the angle.

[0034] During normal operation, the lateral translation module 331 and the lifting cylinder 332 cooperate with each other to drive the disc brush 334 to be located below the roller 312. When the V-shaped roller clamp assembly 323 fixes the wheel hub 100, the lateral translation module 331 and the lifting cylinder 332 cooperate with each other to make the disc brush 334 abut against the inner wall of the wheel hub 100. At this time, the forward and reverse servo motor 324 is started, and the disc brush 334 is used to grind the R angle of the inner wall of the wheel hub 100 during the rotation of the wheel hub 100.

[0035] Compared with the traditional wheel hub 100 grinding device, the present application adopts simple structures to cooperate with each other to complete the grinding of the inner wall of the wheel hub 100 and other places while ensuring the stable clamping of the wheel hub 100.

[0036] The disc-shaped brush 334 is connected to the telescopic end of the lifting cylinder 332 through a forward and reverse driving device 333 .

[0037] The forward and reverse driving device 333 can drive the disc-shaped brush 334 to rotate forward and reverse, so as to improve the grinding efficiency of the wheel hub 100 .

[0038] The forward and reverse driving device 333 includes a driving motor 3331, a driving wheel 3332 connected to the driving motor 3331, an intermediate idler wheel 3333 engaged with the driving wheel 3332, and an output gear 3334 engaged with the intermediate idler wheel 3333. The output gear 3334 is connected to the disc brush 334 through a brush driving shaft 3335.

[0039] The driving wheel 3332, the intermediate idler wheel 3333 and the output gear 3334 are engaged with each other to transmit the power of the driving motor 3331 to the disc brush 334 to drive the rotation of the disc brush 334. Compared with the traditional belt drive, it not only improves the transmission accuracy but also ensures the service life.

[0040] The driving wheel 3332 , the intermediate idler wheel 3333 and the output gear 3334 are arranged in the housing, and the driving wheel 3332 , the intermediate idler wheel 3333 and the output gear 3334 are protected by the housing to prevent external dust from interfering with them and affecting the transmission accuracy and smoothness.

[0041] The shell is arranged at an acute angle relative to the horizontal plane of the roller bracket 311. By setting such an angle, the inner wall of the wheel hub 100 can be better polished to improve the polishing accuracy.

[0042] The rotary clamping device 320 further includes a clamping linear module 322 . The clamping linear module 322 is symmetrically disposed on the supporting base 3221 and is connected to a V-shaped roller clamp assembly 323 .

[0043] Among them, the clamping linear module 322 is a structure that can drive the V-shaped roller clamp assembly 323 to move linearly, which can be screw driven, motor driven or cylinder driven. In this embodiment, cylinder drive is preferred, and the specific structural principle will not be described in detail.

[0044] The clamping linear module 322 is disposed on the transverse plate 321 and is located below the roller 312 . The position of the clamping linear module 322 relative to the transverse plate 321 does not change during the entire clamping and rotation process.

[0045] The V-shaped roller clamp assembly includes a connecting plate 3231 arranged on the clamping linear module 322 and an arc plate 3233 fixed to the connecting plate 3231 through a vertical plate 3232, and L-shaped support plates 3234 are provided at both ends of the arc plate 3233, and the flexible roller 3235 is rotatably connected between the L-shaped support plate 3234 and the arc plate 3233.

[0046] The arc plate 3233 is a shape structure used in conjunction with the wheel hub 100. The wheel hub 100 is supported by the arc plate 3233 and the L-shaped support plate 3234. In addition, the flexible roller 3235 arranged between the L-shaped support plate 3234 and the arc plate 3233 is used to abut against the wheel hub 100, thereby completing the fixation of the wheel hub 100.

[0047] Since the flexible roller 3235 is rotatably arranged, when the flexible roller 3235 rotates, it can synchronously drive the hub 100 to rotate; in addition, due to the arrangement of the arc plate 3233, the hub 100 is limited to rotate without positional deviation.

[0048] The L-shaped support plate 3234 is located between the two rollers 312 to avoid interference with the rollers 312 .

[0049] The upper end surface of the L-shaped support plate 3234 is higher than the upper end surface of the roller 312, and the end of the L-shaped support plate 3234 close to the hub 100 is provided with an inclined surface 32341. When the L-shaped support plate 3234 supports the hub 100, the hub 100 can be slightly raised so that there is a gap between the hub 100 and the roller 312, thereby avoiding interference with the roller 312 during the rotation of the hub 100.

[0050] The rollers 312 are provided in two groups and include a long roller 3121 and a short roller 3122 . The short rollers 3122 are symmetrically arranged on the roller bracket 311 , and the disc-shaped brush 334 is located between the two short rollers 3122 .

[0051] Among them, the functions of the long stick 3121 and the short roller 3122 are both used to transport the wheel hub 100. The symmetrical arrangement of the short roller 3122 is mainly to avoid interference caused by the movement of the disc brush 334.

[0052] A baffle 313 is provided at one end of the short roller 3122 close to the disc-shaped brush 334 . The baffle 313 cooperates with the roller bracket 311 to support the short roller 3122 and facilitate normal use of the short roller 3122 .

[0053] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention rather than to limit them. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the above embodiments within the technical scope disclosed by the present invention, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
