Description

A spoked wheel tightening device Technical Field

[0001] This utility model belongs to the field of spoked wheel technology, and specifically relates to a spoked wheel tightening device. Background Technology

[0002] With the improvement of my country's road conditions and the establishment of supporting facilities for tubeless tires, tubeless tires, which have advantages such as slow air leakage, high safety, good heat dissipation, long life, reduced weight, lower fuel consumption, wear resistance, and suitability for long-distance high-speed driving, have been more widely used. The market potential of spoked tubeless motorcycle wheels has been gradually tapped, and tubeless tires have become more popular. Spoked wheels connect the rim and hub through spokes and maintain air pressure through the inner tube. Due to their good elasticity, strong impact resistance, and ability to adapt to more complex road conditions, they are widely used.

[0003] However, due to the structure of spoked tubeless motorcycle wheels, the rim offset is difficult to control, and the rim tightening efficiency is low, resulting in poor wheel quality. Currently, the rims are tightened manually using wrenches and other devices, which is inefficient and makes it difficult to control the rim offset. Summary of the Invention

[0004] The purpose of this invention is to provide a spoked wheel tightening device to address the aforementioned problems. This device aims to improve the existing spoked tubeless motorcycle wheel rim offset, which is difficult to control precisely by hand, resulting in low tightening efficiency and poor wheel quality.

[0005] The technical solution adopted in this utility model is as follows: A spoked wheel tightening device, the device comprising:

[0006] The tightening assembly includes a template plate and a positioning plate. The positioning plate is mounted on the template plate and is used to support the positioning plate. The positioning plate is provided with a diamond-shaped positioning pin, which is used to circumferentially position the wheel hub. A clamping mandrel is provided at the center of the positioning plate, which is used to center the wheel hub.

[0007] The positioning plate is provided with an angled channel, which is used to accommodate and adapt the torque screwdriver, which is used to tighten the spokes and nut;

[0008] The rim clamping assembly, mounted on the template plate, is used to clamp the rim.

[0009] The above-mentioned structure improves the problems of low efficiency and poor accuracy of existing manual rim making and manual tightening.

[0010] Furthermore, in order to control the relative offset position of the wheel hub, the positioning plate includes a wheel hub positioning base surface, and a diamond-shaped positioning pin is set on the wheel hub positioning base surface. The wheel hub positioning base surface is used to control the relative offset position of the wheel hub.

[0011] Furthermore, in order to control the relative offset position of the wheel rim, the template plate includes a wheel rim positioning base surface and a wheel rim clamping base surface, with a certain height difference between the wheel rim positioning base surface and the wheel rim clamping base surface. The inner circumferential stop is set between the wheel rim positioning base surface and the wheel rim clamping base surface; the inner circumferential stop is perpendicular to the wheel rim positioning base surface and the wheel rim clamping base surface, and the inner circumferential stop is used to assist in center positioning of the wheel rim.

[0012] Among them, the rim positioning base surface, the hub positioning base surface, and the rim clamping base surface are parallel to each other.

[0013] Furthermore, there are multiple oblique channels, with a total number of 32+4n, where n=0,1,2.

[0014] Furthermore, the rim clamping assembly has a padding layer on its surface, which is used to protect the rim.

[0015] Furthermore, the device also includes a base with a bracket on it, which supports the tightening assembly and connects the tightening assembly to the base;

[0016] The bracket is equipped with a horizontal rotating shaft and a vertical rotating shaft. The bracket is rotatably connected to the base via the vertical rotating shaft, and the tightening assembly is rotatably connected to the bracket via the horizontal rotating shaft.

[0017] Furthermore, the base is equipped with omnidirectional casters, which allow the device to move.

[0018] Furthermore, a locking component is provided on the transverse rotating shaft, which is used to lock the tightening component.

[0019] Furthermore, the oblique channel is set on the back of the hub positioning base.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. This utility model incorporates a tightening assembly. The template plate and positioning plate of the tightening assembly are respectively adapted to the rim and hub for precise positioning of the rim and hub. A torque screwdriver is positioned below the positioning plate and tightens the spokes using the torque screwdriver. By precisely positioning the wheel through the tightening assembly and then tightening the spokes and spoke nuts using the torque screwdriver, the deviation of the rim offset can be reduced, and the tightening efficiency of the wheel spokes can be improved, thereby improving the quality of the wheel.

[0022] 2. This utility model improves the tightening efficiency of spokes and nuts by setting a transverse rotating shaft and a longitudinal rotating shaft.

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The tightening device of this invention is applied to the tightening process of spoked tubeless motorcycle wheel rims to ensure that the assembly offset, spoke torque, wheel runout, and wheel dynamic imbalance of the wheel 111 are at a high level. In this embodiment, the spoke / strip mother assembly of the coarsely woven spoked tubeless motorcycle wheel rim consists of 36 sets.

[0031] As shown in Figure 3, the spoke wheel tightening device includes a base 100, a bracket 200 and a tightening assembly 300. The tightening assembly 300 is connected to the base 100 through the bracket 200. The wheel 111 is set on the tightening assembly 300. The tightening assembly 300 is used to rim and tighten the spokes.

[0032] As shown in Figures 1 and 2, the tightening assembly 300 includes a template plate 301 and a positioning plate 302. The positioning plate 302 is mounted on the template plate 301, and the template plate 301 supports the positioning plate 302. The positioning plate 302 is provided with a diamond-shaped positioning pin 303, which is used for circumferential positioning of the wheel hub. A clamping mandrel 306 is provided at the center of the positioning plate 302, which is used for center positioning of the wheel hub.

[0033] The positioning plate 302 and the template 301 are connected by mounting screws on the flange face;

[0034] The positioning plate 302 is provided with an inclined channel 307, which is used to accommodate and adapt the torque screwdriver, which is used to tighten the spokes and nut; and the inclined channel 307 is set according to the characteristics of the wheel hub structure.

[0035] The rim clamping assembly 309 is mounted on the template plate 301 and is used to clamp the rim.

[0036] By placing the wheel 111 on the tightening assembly 300, the hub and rim of the wheel 111 are respectively engaged with the positioning plate 302 and the template plate 301, which facilitates precise positioning and engagement of the wheel 111.

[0037] The template plate 301 can be changed to a suitable size according to the actual situation of the wheel 111.

[0038] Example 1

[0039] As shown in Figures 1-2, in one embodiment of the present invention, the positioning disc 302 includes a hub positioning base surface 304, and a diamond-shaped positioning pin 303 is disposed on the hub positioning base surface 304. The hub positioning base surface 304 is used to control the relative offset position of the hub.

[0040] The brake surface flange of the coarse rib wheel 111 is pressed against the hub positioning base 304 for axial positioning of the hub. The brake surface flange hole of the coarse rib wheel 111 is used for circumferential positioning of the hub through the diamond positioning pin 303. After the diamond positioning pin 303 positions the hub circumferentially, the clamping mandrel 306 first positions and clamps the center of the hub. Thus, the positioning disc 302 can accurately position the hub.

[0041] Example 2

[0042] As shown in Figures 2 and 3, another embodiment of this utility model is that the template plate 301 includes a rim positioning base surface 305 and a rim pressing base surface 310, with a certain height difference between the rim positioning base surface 305 and the rim pressing base surface 310. An inner circumferential stop 308 is disposed between the rim positioning base surface 305 and the rim pressing base surface 310. The inner circumferential stop 308 is perpendicular to the rim positioning base surface 305 and the rim pressing base surface 310, and is used to assist in center positioning of the rim.

[0043] Among them, the rim positioning base surface 305, the hub positioning base surface 304, and the rim clamping base surface 310 are parallel to each other.

[0044] The rim end face of the coarse-woven rim wheel 111 is attached to the rim positioning base 305 on the template plate 301 to achieve axial positioning in the height direction of the rim. The rim positioning base 305, the hub positioning base 304 and the rim pressing base 310 form a certain height difference. The inner circumferential stop 308 is the vertical surface of the height difference formed by the rim positioning base 305 and the rim pressing base 310. The inner circumferential stop 308 is used to center the rim. By manually adjusting the circumferential position of the rim, the protruding positions of the spoke nut are relatively equal on the left and right. The setting of the inner circumferential stop 308 can achieve precise control of the wheel runout.

[0045] Example 3

[0046] As shown in Figure 2, another embodiment of this utility model is that there are multiple inclined channels 307, the number of which is 32+4n, where n=0,1,2.

[0047] The torque screwdriver tightens the 18 sets of nuts on the drive side of the coarse rim wheel 111 sequentially through the inclined channel 307, thereby precisely controlling the tightening range of the nuts.

[0048] Provided that the hub and rim are accurately positioned, a fixed torque wrench is used to tighten the spokes and nut in an orderly manner through the oblique channel 307, thereby achieving precise control of the torque of the spokes and nut.

[0049] Example 4

[0050] In another embodiment of this utility model, the surface of the rim clamping assembly 309 is provided with a soft pad layer, which is used to protect the rim.

[0051] The cushion layer is used to protect the end face of the rim, and the rim clamping assembly 309 clamps the rim in sequence at intervals of one quadrant position.

[0052] Example 5

[0053] As shown in Figure 1, another embodiment of the present invention includes a base 100, on which a bracket 200 is provided. The bracket 200 is used to support the tightening assembly 300 and connect the tightening assembly 300 to the base 100.

[0054] The bracket 200 is provided with a transverse rotating shaft 202 and a longitudinal rotating shaft 201. The bracket 200 is rotatably connected to the base 100 through the longitudinal rotating shaft 201, and the bracket 200 rotates 360° around the longitudinal rotating shaft 201. The tightening assembly 300 is rotatably connected to the bracket 200 through the transverse rotating shaft 202, and the tightening assembly 300 rotates 360° around the transverse rotating shaft 202. Thus, the nut and spokes on the left and right sides of the wheel are tightened by a torque screwdriver through the oblique channel 307.

[0055] Example 6

[0056] As shown in Figures 1-3, another embodiment of this utility model is that a locking component 203 is provided on the transverse rotating shaft 202, and the locking component 203 is used to lock the tightening component 300.

The brake surface flange hole of the coarse woven rim wheel 111 is circumferentially positioned by the diamond positioning pin 303. The hub of the coarse woven rim wheel 111 is axially clamped by the clamping mandrel 306 with an open pad.

[0059] The rim end face of the coarse woven rim wheel 111 is closely attached to the rim positioning base 305 on the template 301 for axial positioning of the rim height; the inner circumferential stop 308 on the template 301 is used to center the rim, and the axial position of the rim is manually adjusted so that the protruding positions of the spokes and nut are roughly equal; the rim clamping assembly 309 clamps the rim in sequence at intervals of one quadrant position.

[0060] With the hub and rim effectively positioned, the locking assembly 203 is used to position and lock the tightening assembly 300. A fixed torque wrench of 4.0 N·m is used to pre-tighten the eight nuts located at quadrant points through the oblique channel 307, spacing them one quadrant apart. The tightening assembly 300 is then unlocked via the locking assembly 203, and the tightening assembly 300 is flipped via the transverse rotating shaft 202, and then fixed again via the locking assembly 203. A fixed torque wrench is then used to... A 5.0 N·m torque wrench is used to tighten the 18 sets of nuts on the brake side of the coarse woven rim wheel 111 sequentially through the oblique channel 307; the tightening assembly 300 is then unlocked again through the locking assembly 203, the tightening assembly 300 is flipped through the transverse rotating shaft 202, and then the tightening assembly 300 is fixed through the locking assembly 203; a 5.0 N·m torque wrench is used to tighten the 18 sets of nuts on the drive side of the coarse woven rim wheel 111 sequentially through the oblique channel 307, thereby completing the tightening operation.
