Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and more specifically, to a testing device and method for detecting the position of spoke holes in motorcycle spoke wheels. Background Technology

[0002] Spoke-type wheels are widely used in non-motorized vehicles, motorcycles, and some automobiles due to their lightweight and high structural strength. The positional accuracy of the spoke holes on the outer rim of a spoke-type wheel directly determines the precision of the spoke assembly and the wheel's circular runout, thus affecting the overall vehicle's driving stability and safety. Therefore, strict positional accuracy testing is required after the spoke holes are machined.

[0003] Currently, the industry mostly uses coordinate measuring machines (CMMs) for hole-by-hole sampling to inspect the positional accuracy of spoke holes. This method offers high accuracy, but it has a long inspection cycle and high equipment purchase and maintenance costs, making it unsuitable for the rapid full inspection or sampling requirements in mass production processes. Some simple inspection tools use pin-type single-hole comparison, which can only determine whether a single hole is qualified and cannot simultaneously inspect the circumferential spacing and angular distribution uniformity of multiple holes, resulting in low inspection efficiency. If circumferential rotational alignment is required, a high-precision electrically controlled rotary table and servo control system are also needed, further increasing the complexity of the equipment and manufacturing costs, which is not conducive to its widespread application in small and medium-sized production scenarios. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device and method for detecting the position of spoke holes in motorcycle spoke wheels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention discloses a device for detecting the position of the spoke holes on the outer ring of a spoked wheel, comprising a support column, a detection platform, a laser assembly, and a display module. The detection platform is rotatably mounted on the upper end of the support column and includes a positioning block for centering and fixing the outer ring of the spoked wheel. Multiple laser assemblies are provided, and the laser assemblies can be inserted into the spoke holes on the outer ring of the spoked wheel. The laser assemblies can generate laser beams and project them onto the display module to form a projected light spot.

[0007] Preferably, the testing table includes a chuck body, on which several positioning blocks are evenly distributed in a circumferential shape. The testing table also includes an adjustment handle, which can be used to adjust the radial position of the positioning blocks.

[0008] Preferably, the laser assembly includes a laser generator and a detection rod coaxially connected, the outer diameter of the detection rod being adapted to the diameter of the spoke hole, and being able to be inserted into the spoke hole and kept relatively fixed.

[0009] Preferably, the lower part of the chuck body has a mounting hole, the upper end of the support column extends into the mounting hole, and a bearing is provided between the mounting hole and the upper end of the support column.

[0010] Preferably, a fine-tuning handle is also included, which is used to rotate the testing stage at a small angle.

[0011] Preferably, the fine-tuning handle includes a rotating shaft, which is rotatably mounted on a support column. A drive wheel is fixedly mounted on the rotating shaft, and the outer circumference of the drive wheel abuts against the lower end face of the chuck body.

[0012] Preferably, the fine-tuning handle includes a rotating shaft, which is rotatably mounted on a support column. A bevel gear is fixedly connected to the rotating shaft, and a bevel gear ring is mounted on the lower end face of the chuck body. The bevel gear meshes with the bevel gear ring.

[0013] Preferably, the chuck body has a clearance opening, which provides clearance space for the laser assembly inserted into the lower spoke hole of the outer ring of the spoke wheel, so as to avoid blocking the projection path of the laser beam.

[0014] A method for detecting the position of the spoke holes on the outer ring of a spoked wheel includes the following steps:

[0015] Step 1: Place the outer ring of the spoked wheel on a rotatable testing platform and use the positioning block to center and fix the outer ring of the spoked wheel;

[0016] Step 2: Insert the laser component into any adjacent spoke hole on the outer ring of the spoke wheel. The laser component generates a laser beam that is projected onto the display module to form a projection spot.

[0017] Step 3: The display module calls up the standard test pattern that matches the outer ring of the spoke wheel to be tested, and displays the tolerance area for each hole position;

[0018] Step 4: Rotate the inspection table and observe whether the projected light spots are simultaneously located within the corresponding tolerance area. If all projected light spots are simultaneously located within the tolerance area preset by the standard pattern, the spoke hole position accuracy is deemed to be qualified; otherwise, it is deemed to be unqualified.

[0019] As a preferred option, in step 4, the detection stage is first rotated so that at least one projected spot coincides with the center of the tolerance area of ​​the corresponding aperture position in the standard pattern. Then, the circumferential position of the detection stage is finely adjusted to observe whether the remaining projected spots can be simultaneously located within the corresponding tolerance area.

[0020] As a preferred option, the standard test pattern is generated based on the wheel hub design parameters. The standard pattern includes the theoretical hole position coordinates and a visualized tolerance area centered on the theoretical hole position coordinates.

[0021] Preferably, the insertion end size of the laser component is adapted to the aperture of the spoke hole.

[0022] The beneficial effects of this invention are: by inserting multiple laser components to perform projection comparison simultaneously, the hole spacing, angle and distribution uniformity can be detected in one go; by manually rotating the detection stage, the light spot can be aligned with the tolerance area of ​​the standard spectrum, eliminating the need for high-precision electrically controlled rotating components and reducing the complexity of the device.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1-5As shown, a spoke wheel outer ring spoke hole position detection device mainly includes four parts: a support column 1, a detection platform 2, a laser assembly 3, and a display module 4. The detection platform 2 is rotatably mounted on the upper end of the support column 1 and can rotate freely around its own axis. The detection platform 2 is provided with a positioning block 22 for centering and clamping the spoke wheel outer ring 6 placed on the detection platform 2. At least two laser assemblies 3 are provided, which are inserted into the spoke holes 61 of the spoke wheel outer ring 6 during use and can emit laser beams outward. The laser beams are projected onto the display module 4 in front to form a clear projection spot.

[0031] like Figure 4 As shown, the main body of the inspection table 2 is a chuck body 21, and several positioning blocks 22 are evenly distributed circumferentially along the circumference of the chuck body 21. In this embodiment, there are three positioning blocks 22, forming a three-jaw centering structure. An adjustment handle 23 is also provided on the chuck body 21. The adjustment handle 23 drives the bevel gear disk inside the chuck body 21 to rotate, and the bevel gear disk drives the positioning blocks 22 mounted on it to move radially, thereby adjusting the clamping diameter to adapt to the spoke wheel outer ring 6 of different specifications, ensuring that the workpiece is coaxially fixed with the chuck body 21.

[0032] The lower part of the chuck body 21 has a mounting hole 212. The upper end of the support column 1 extends into the mounting hole 212. A bearing is installed between the inner wall of the mounting hole 212 and the outer wall of the support column 1. The bearing enables the test table 2 to rotate with low resistance relative to the support column 1, which facilitates manual rotation to adjust the circumferential angle.

[0033] A through clearance opening 211 is provided on the side wall of the chuck body 21. When detecting the spoke hole 61 at the lower position of the outer ring 6 of the spoke wheel, the laser component 3 can pass through the clearance opening 211 and be inserted into the corresponding spoke hole 61. The clearance opening 211 will not hinder the insertion of the laser component 3, nor will it block the projection path of the laser beam, ensuring that the laser can be normally projected onto the display module 4 to form a light spot, thereby realizing the detection of spoke holes 61 at different axial heights.

[0034] like Figure 5 As shown, the laser assembly 3 consists of a laser generator 31 and a detection rod 32 coaxially and fixedly connected. The detection rod 32 serves as the insertion end, and its outer diameter is matched with the aperture of the spoke hole 61. After insertion, it can ensure that the beam axis of the laser generator 31 coincides with the axis of the spoke hole 61, ensuring that the position of the projected light spot can accurately reflect the actual position of the spoke hole 61.

[0035] To achieve precise small-angle adjustments to the testing platform 2, the device is also equipped with a fine-tuning handle 5, which is illustrated below through two embodiments:

[0036] Example 1

[0037] like Figure 3As shown, the fine-tuning handle 5 includes a rotating shaft 51, which is horizontally mounted on the side wall of the support column 1. A drive wheel 52 is fixedly mounted on the inner end of the rotating shaft 51, and its outer circumferential surface abuts against the lower end surface of the chuck body 21. The drive wheel 52 is made of rubber or polyurethane to increase the friction between it and the chuck body 21. When the handwheel at the outer end of the rotating shaft 51 is rotated, the drive wheel 52 rotates synchronously, driving the chuck body 21 to rotate around the axis at a small angle by friction, thereby achieving precise alignment of the light spot.

[0038] Example 2

[0039] like Figure 4 As shown, the fine-tuning handle 5 includes a rotating shaft 51, which is rotatably mounted on the side wall of the support column 1 in a horizontal direction. A bevel gear 53 is fixedly connected to the inner end of the rotating shaft 51. Correspondingly, a bevel gear ring 54 is coaxially fixedly mounted on the lower end face of the chuck body 21, and the bevel gear 53 and the bevel gear ring 54 mesh with each other. When the handwheel at the outer end of the rotating shaft 51 is rotated, the bevel gear 53 drives the bevel gear ring 54 to rotate, which in turn drives the chuck body 21 to rotate synchronously. The gear meshing transmission ensures the accuracy of the fine-tuning angle and avoids slippage deviation.

[0040] The display module 4 is located on one side of the testing platform 2, opposite to the light emission direction of the laser component 3. It contains pre-stored standard testing maps for wheel hubs of different specifications. These standard testing maps are generated based on the wheel hub's design parameters, including the theoretical coordinates of each spoke hole and a visual tolerance area 41 centered on these theoretical coordinates and generated according to tolerance requirements. During testing, the corresponding specification's map can be retrieved to visually compare the positional relationship between the light spot and the tolerance area 41.

[0041] Based on the aforementioned testing equipment, the specific steps of the spoke hole position measurement method are as follows:

[0042] Step 1: Clamp the workpiece. According to the specifications of the outer ring 6 of the spoke wheel to be tested, rotate the adjusting handle 23 to adjust the position of the positioning block 22. The positioning block 22 moves synchronously along the radial direction of the chuck body 21 and abuts against the inner side of the outer ring 6 of the spoke wheel, thus completing the centering and clamping of the outer ring 6 of the spoke wheel.

[0043] Step 2: Install the laser assembly. Select any two or more adjacent spoke holes 61 on the outer ring 6 of the spoke wheel, insert the detection rod 32 end of the laser assembly 3 into the spoke hole 61, and after ensuring that it is properly inserted, turn on the laser generator 31. The laser beam is projected forward onto the screen of the display module 4 to form a projection spot corresponding to each spoke hole 61.

[0044] Step 3: Call the standard pattern. In the display module 4, select the standard test pattern that matches the model 6 of the outer ring of the spoke wheel to be tested. The screen will display the tolerance area 41 corresponding to each hole position. The center of the tolerance area 41 is the theoretical coordinate of the hole position, and the range corresponds to the design tolerance requirements.

[0045] Step 4: Rotation Inspection and Judgment. Manually rotate the inspection table 2 to drive the spoke wheel outer ring 6 and the laser component 3 to rotate synchronously, and observe the position of each projected light spot; when one of the projected light spots is roughly aligned with the center of the corresponding tolerance area 41, operate the fine adjustment handle 5 to make a small-angle fine adjustment, and observe all the remaining projected light spots. If all the light spots fall within their respective tolerance areas 41, the position of the spoke hole 61 of the spoke wheel outer ring 6 is judged to be qualified; if any light spot exceeds the tolerance area 41, it is judged to be unqualified.

[0046] After the inspection is completed, turn off the laser generator 31, pull out the laser assembly 3, release the positioning block 22 to remove the workpiece, and then proceed to the next inspection.

[0047] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
