Description

Technical Field

[0001] The utility model relates to the application field of wheel hub processing and grinding technology, in particular to a rotary clamping tool for positioning the wheel hub. Background Art

[0002] In the processing of mechanical parts, grinding, polishing and deburring are necessary steps in the processing of wheel hubs. After the processing of the wheel hub 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 causes damage to 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 rotating clamping tool for positioning the wheel hub. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a rotary clamping tool for positioning the wheel hub. When the tool clamps and fixes the wheel hub, the forward and reverse servo motor can directly drive the wheel hub to rotate forward and reverse on the rotary clamping device, which is simpler in structure than the wheel hub rotating device in the prior art.

[0004] The technical solution of the utility model is: a rotary clamping tool for positioning a wheel hub, comprising a double-sided roller line, the double-sided roller line comprising a roller bracket and a plurality of rollers provided on the roller bracket; the roller bracket is fixed with a rotary clamping device via a transverse plate, the rotary clamping device comprising symmetrically arranged V-shaped roller clamp assemblies, the V-shaped roller clamp assemblies being provided with flexible rollers abutting against the side wall edges of the wheel hub, and the wheel hub placed between the two V-shaped roller clamp assemblies being clamped and fixed by the flexible rollers;

[0005] It also includes a forward and reverse servo motor that drives the flexible roller to rotate and is arranged on the V-shaped roller clamp assembly. The output end of the forward and reverse servo motor is provided with a driving wheel that cooperates with the flexible roller. The driving wheel is in contact with the flexible roller to drive the wheel hub to rotate.

[0006] Furthermore, the rotary clamping device also includes a clamping linear module, which is symmetrically arranged on the bearing seat and connected to the V-shaped roller clamp assembly.

[0007] Furthermore, the clamping linear module is arranged on the transverse plate and is located below the roller.

[0008] Furthermore, the V-shaped roller clamp assembly includes a connecting plate arranged on the clamping linear module and an arc plate fixed to the connecting plate through a vertical plate, L-shaped support plates are provided at both ends of the arc plate, and the flexible roller is rotatably connected between the L-shaped support plate and the arc plate.

[0009] Furthermore, the L-shaped support plate is located between the two rollers.

[0010] Furthermore, the upper end surface of the L-shaped support plate is higher than the upper end surface of the roller, and an inclined surface is provided at one end of the L-shaped support plate close to the hub.

[0011] Furthermore, the V-shaped roller clamp assembly is arranged above the roller, and a gap is provided between the V-shaped roller clamp assembly and the roller.

[0012] Furthermore, it also includes a polishing robot arranged on the double-sided roller line.

[0013] The beneficial technical effects of the utility model are:

[0014] The arc-shaped plate and the L-shaped support plate are arranged to support the wheel hub, and at the same time, the flexible roller arranged between the L-shaped support plate and the arc-shaped plate abuts against the side wall edge of the wheel hub to complete the fixation of the wheel hub; furthermore, a forward and reverse servo motor capable of driving the flexible roller to rotate is provided on the arc-shaped plate. Since the flexible roller is easy to abut against the side wall of the wheel hub, when the flexible roller rotates, it can synchronously drive the wheel hub to rotate; at the same time, since the arc-shaped plate is a shape structure used in conjunction with the wheel hub, no positional displacement will occur when the wheel hub rotates.

[0021] 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.

[0022] 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.

[0023] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the descriptions in the embodiments and shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. 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.

[0024] like Figure 1-Figure 3 As shown, the utility model specifically relates to a rotary clamping tool for positioning a wheel hub, comprising a double-sided roller line 310, wherein the double-sided roller line 310 comprises a roller support 311 and a plurality of rollers 312 provided on the roller support 311; the roller support 311 is fixed with a rotary clamping device 320 via a transverse plate 321, and the rotary clamping device 320 comprises symmetrically arranged V-shaped roller clamp assemblies 323, wherein the V-shaped roller clamp 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 clamp assemblies 323 is clamped and fixed by the flexible rollers 3235;

[0025] It also includes a forward and reverse servo motor 324 that drives the flexible roller 3235 to rotate and is provided on the V-shaped roller clamp assembly 323. The output end of the forward and reverse servo motor 324 is provided with a driving wheel 3241 that cooperates with the flexible roller 3235. The driving wheel 3241 is in contact with the flexible roller 3235 to drive the wheel 3241 hub 100 to rotate.

[0026] 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 .

[0027] 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.

[0028] 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 flexible roller 3235 is driven to rotate by the forward and reverse servo motor 324. 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.

[0029] 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 .

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] The L-shaped support plate 3234 is located between the two rollers 312 to avoid interference with the rollers 312 .

[0036] 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.

[0037] The V-shaped roller clamp assembly 323 is disposed above the roller 312 , with a gap between the V-shaped roller clamp assembly 323 and the roller 312 .

[0038] It also includes a polishing robot 330 arranged on the double-sided roller line 310.

[0039] 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.
