Description

Technical Field

[0001] This utility model relates to the field of spoke testing technology, and in particular to a multi-station rapid tensile testing device. Background Technology

[0002] Wheel spokes typically consist of a spoke bar, a first spoke cap at one end of the spoke bar, and a second spoke cap at the other end of the spoke bar. The first spoke cap is used to connect with the rim, and the second spoke cap is used to connect with the hub.

[0003] In the field of spoke testing, an important test is to determine whether the spokes can withstand tensile force. However, current spoke tensile testing equipment has very low efficiency in loading and unloading spokes, which seriously affects the efficiency of spoke tensile force qualification testing. For example, a Chinese utility patent published on June 25, 2024, entitled "An Auxiliary Device for Spoke Tensile Force Testing" (publication number CN221224388U), uses two fixed plates, one on one side and the other on the other, to fix the spoke caps. When loading spokes, the spoke caps, i.e., the top of the spokes, need to be placed in the fixed plates and then bolted to tighten the fixed plates. Therefore, the efficiency of loading spokes is very low, which affects the testing efficiency.

[0004] Because spoke tension testing equipment is a fully automated system, it often requires human assistance for testing. Currently, one device can only test the tension of one spoke at a time, which is a serious waste of human resources.

[0005] Therefore, a spoke tensile testing device with a fast testing speed is needed. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this utility model provides a multi-station rapid tensile testing device to solve the problem of slow speed in current spoke tensile testing.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-station rapid tensile testing device, including a workbench and at least two tensile testing mechanisms disposed on the workbench; the tensile testing mechanism includes a tensile sensor, a first limiting unit, a second limiting unit, and a driving unit; the first limiting unit has a first limiting slot for placing the spoke rod and limiting the spoke cap, and the second limiting unit has a second limiting slot for placing the spoke rod and limiting the spoke cap; the first limiting slot and the second limiting slot are approximately located on the same horizontal plane; the driving unit is used to drive the first limiting unit to move closer to or further away from the second limiting unit, and the tensile sensor is disposed on the first limiting unit or the second limiting unit to obtain real-time tensile data of the spokes.

[0008] Preferably, there are 3 to 6 tensile testing mechanisms, which are parallel to each other and spaced apart along the length of the spokes.

The first fixed seat is provided with first positioning holes spaced apart along the length direction of the spokes. The first fastening bolt can pass through the first limiting component and be threaded into the first positioning holes. The first limiting component is used to form a first limiting through groove with the first fixed seat.

[0010] The second limiting unit includes a second fixed seat, a second limiting component, and a second fastening bolt. The second fixed seat is provided with second positioning holes spaced apart along the length direction of the spokes. The second fastening bolt can pass through the second limiting component and be threaded into the second positioning holes. The second limiting component is used to form a second limiting through groove with the second fixed seat.

[0011] Preferably, the first limiting component includes two first limiting blocks, and the first limiting blocks are provided with elongated through slots for the first fastening bolts to pass through, the direction of the elongated through slots being perpendicular to the length direction of the spokes; and the first positioning holes are in at least two rows on the first fixing seat;

[0012] The second limiting component includes two second limiting blocks, and the second limiting blocks are provided with elongated through slots through which the second fastening bolts pass, the direction of which is perpendicular to the length direction of the spoke placement; and the second positioning holes are in at least two rows on the second fixing seat.

[0013] Preferably, each first limiting block is equipped with two first fastening bolts, and each second limiting block is equipped with two second fastening bolts.

[0014] Preferably, the driving unit includes a drive motor, a transmission threaded rod, a guide rail, and a slider. The slider is slidably disposed on the guide rail. The transmission threaded rod cooperates with the slider via a lead screw nut. The first fixed seat is mounted on the slider. The drive motor controls the first limiting unit to move closer to or further away from the second limiting unit by driving the transmission threaded rod.

[0015] Preferably, the tensile testing mechanism further includes a first dust cover and a second dust cover. The first dust cover is hinged to the first fixed base and is located above the first limiting component when closed. The second dust cover is hinged to the second fixed base and is located above the second limiting component when closed.

[0016] Preferably, it also includes a test display screen, and the tension sensors of the plurality of tensile testing mechanisms are all signal-connected to the test display screen.

[0017] Preferably, the tensile testing mechanism further includes a position sensor, which is located near the second limiting unit. The position sensor is signal-connected to the driving unit to prevent the first limiting unit from getting too close to the second limiting unit.

[0018] Preferably, the positioning sensor is slidably mounted on the guide rail.

[0019] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0020] This invention utilizes a multi-station design, with at least two tensile testing mechanisms operating in parallel on the same workbench, replacing traditional single-station equipment. It fully utilizes the testing time of the tensile testing mechanisms, allowing workers to continuously load and unload multiple tensile testing mechanisms. By setting the limiting slots at both ends of the test spokes on approximately the same horizontal plane, the spoke rods at both ends of the spokes can be quickly placed into the first and second limiting slots. When testing spokes of the same model, there is no need to pay too much attention to the positional relationship between the spoke cap and the limiting slot, nor is it necessary to manually adjust the width of the limiting slot, thus achieving rapid loading and unloading.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0030] like Figures 1-7 As shown, this utility model provides a multi-station rapid tensile testing device for testing the tensile strength of wheel spokes, belonging to the field of spoke testing technology. The device includes a workbench 1, multiple tensile testing mechanisms 2 spaced apart along the length of the workbench 1, and a test display screen 17 connected to each tensile testing mechanism 2 via signal connections. Each tensile testing mechanism 2 independently completes the clamping, tensile force application, and data acquisition of the spoke X, significantly improving testing efficiency through a multi-station parallel design.

[0031] Preferably, on the workbench 1, 3 to 6 tensile testing mechanisms 2 are arranged parallel to and spaced apart along the length direction of the spokes X; in this embodiment, there are 4. By increasing the number of workstations and optimizing the layout, and arranging them parallel to each other along the length direction of the spokes X, multiple spokes X can be tested simultaneously at the same time. When workers are testing, they can load and unload the spokes X sequentially using the tensile testing mechanisms 2, significantly increasing the testing capacity per unit time. The parallel arrangement avoids interference between workstations, ensuring that each workstation works independently, and improving the consistency and stability of the tests.

[0032] The tensile testing mechanism 2 includes a tensile sensor, a first limiting unit 3, a second limiting unit 4, and a driving unit 5. The first limiting unit 3 has a first limiting slot 6 for placing the spoke rod X1 and limiting the spoke cap X2, and the second limiting unit 4 has a second limiting slot for placing the spoke rod X1 and limiting the spoke cap X2. The first limiting slot 6 and the second limiting slot are approximately located on the same horizontal plane. The driving unit 5 is used to drive the first limiting unit 3 to move closer to or further away from the second limiting unit 4.

[0033] The tension sensor is disposed at the first limiting unit 3 or the second limiting unit 4 to obtain real-time tension data of spoke X. In this embodiment, the tension sensor is disposed at the second limiting unit 4, which is convenient for wiring connections as the second limiting unit 4 can be directly fixed on the workbench 1.

[0034] Therefore, this embodiment uses a multi-station design with four tensile testing mechanisms 2 arranged in parallel on the same workbench 1, replacing the traditional single-station equipment. This fully utilizes the testing time of the tensile testing mechanisms 2, allowing workers to continuously load and unload multiple tensile testing mechanisms 2, significantly improving the efficiency of spoke X tensile testing. By setting the limiting slots at both ends of the test spoke X on approximately the same horizontal plane, the spoke rods X1 at both ends of the spoke X can be quickly placed into the first limiting slot 6 and the second limiting slot. When testing spokes of the same model, there is no need to pay too much attention to the positional relationship between the spoke cap X2 and the limiting slot, nor is it necessary to manually adjust the width of the limiting slot, thus achieving rapid loading and unloading.

[0035] The first limiting unit 3 includes a first fixing seat 7, a first limiting component, and a first fastening bolt 19. The first fixing seat 7 is provided with first positioning holes 11 spaced apart along the length direction of the spokes X. The first fastening bolt 19 can pass through the first limiting component and be threadedly engaged with the first positioning holes 11. The first limiting component is used to form a first limiting through groove 6 with the first fixing seat 7. The second limiting unit 4 includes a second fixing seat 10, a second limiting component, and a second fastening bolt. The second fixing seat 10 is provided with second positioning holes spaced apart along the length direction of the spokes X. The second fastening bolt can pass through the second limiting component and be threadedly engaged with the second positioning holes. The second limiting component is used to form a second limiting through groove with the second fixing seat 10.

[0036] The first limiting unit 3 engages with the first fastening bolt 19 via the first positioning hole 11 on the first fixed base 7. Multiple first positioning holes 11 are spaced apart along the length direction of the spoke X, forming an adjustable first limiting groove 6 between the first limiting assembly (two first limiting blocks 8) and the first fixed base 7. Similarly, the second limiting unit 4 forms an adjustable second limiting groove with the second positioning hole and the second fastening bolt. By adjusting the fastening bolt and different positioning holes, the position of the limiting groove on the fixed base is changed to accommodate spokes X of different lengths.

[0037] The adjustable design of the limiting slot allows the equipment to adapt to spokes of different lengths, expanding its applicability. The modular combination of the fixed base and the limiting component simplifies the adjustment of the limiting slot and reduces the changeover and debugging time.

[0038] Please refer to Figure 4 and Figure 5 The limiting component can be a block structure with a limiting through groove with an open top. In this embodiment, the first limiting component includes two first limiting blocks 8, and the second limiting component includes two second limiting blocks, so that the two limiting blocks are fixed on the fixing base at intervals, and a limiting through groove is formed between the two limiting blocks.

[0039] Furthermore, the first limiting block 8 is provided with an elongated through groove 9 through which the first fastening bolt 19 passes, the direction of the elongated through groove 9 being perpendicular to the length direction of the spoke X; and the first positioning holes 11 are in at least two rows on the first fixing seat 7; the second limiting component includes two second limiting blocks, and the second limiting block is provided with an elongated through groove 9 through which the second fastening bolt passes, the direction of the elongated through groove 9 being perpendicular to the length direction of the spoke X; and the second positioning holes are in at least two rows on the second fixing seat 10.

[0040] Therefore, the first limiting assembly consists of two first limiting blocks 8, each of which has an elongated through groove 9 perpendicular to the length direction of the spoke X, allowing the first fastening bolt 19 to slide in the vertical direction; the first fixing seat 7 is provided with at least two rows of first positioning holes 11 arranged along the length direction of the spoke X. The first row corresponds to the first first limiting block 8, and the second row corresponds to the second first limiting block 8. The distance between each first limiting block 8 can be adjusted by the position of the first fastening bolt 19 in the elongated through groove 9, thereby quickly accommodating spokes X of different diameters.

[0041] The combination of the elongated through-slot 9 and the multi-row positioning holes enables flexible adjustment of the limiting through-slot in both axial and radial dimensions: the through-slot width can be adjusted along the length of the spoke X via the elongated through-slot 9 to match the diameter of the spoke X; the through-slot length can be adjusted along the length of the spoke X via the multi-row positioning holes to match the length of the spoke rod X1. This significantly improves the equipment's compatibility with spokes of different specifications X.

[0042] Preferably, each first limiting block 8 is equipped with two first fastening bolts 19, and each second limiting block is equipped with two second fastening bolts. This improves the stability of the limiting blocks on the fixed seat, preventing tilting even under significant pressure. The double-bolt fixing design enhances the stability of the limiting blocks, preventing displacement of the through-slot position due to loosening of a single bolt, ensuring that the spoke X is reliably clamped during testing, and preventing test data errors or the risk of spoke X falling off due to unstable clamping.

[0043] Please refer to Figure 2 and Figure 3The driving unit 5 includes a driving motor 12, a transmission threaded rod 13, a guide rail 14, and a slider. The slider is slidably disposed on the guide rail 14. The transmission threaded rod 13 cooperates with the slider via a screw nut. The first fixed seat 7 is installed on the slider. The driving motor 12 controls the first limiting unit 3 to move closer to or further away from the second limiting unit 4 by driving the transmission threaded rod 13.

[0044] The drive unit 5 adopts a screw-slider transmission structure: the drive motor 12 drives the slider to slide linearly along the guide rail 14 through the transmission threaded rod 13. The first fixed seat 7 installed on the slider moves with the slider, thereby causing the first limiting unit 3 to move closer to or further away from the second limiting unit 4. By controlling the rotation amount of the motor (such as the number of pulses of a stepper motor / servo motor), the moving distance of the first limiting unit 3 can be precisely controlled. The screw-slider transmission structure has the characteristics of high precision and high response, which can realize precise adjustment of spoke tension; the cooperation between the guide rail 14 and the slider ensures the smoothness of movement and avoids test errors caused by shaking; the automated drive replaces manual adjustment, greatly improving test efficiency.

[0045] The tensile testing mechanism 2 described in this embodiment further includes a first dust cover 15 and a second dust cover 16. The first dust cover 15 is hinged to the first fixed base 7 and is located above the first limiting component when closed. The second dust cover 16 is hinged to the second fixed base 10 and is located above the second limiting component when closed. The first dust cover 15 is hinged to the top of the first fixed base 7 and covers the top opening of the first limiting component (two first limiting blocks 8) when closed. Similarly, the second dust cover 16 covers the second limiting component. The dust cover can prevent metal debris, dust, etc. generated during the test from falling into the limiting groove, avoiding spoke jamming or poor sliding of the limiting blocks caused by debris accumulation. At the same time, the dust cover can protect the limiting component from external impact or contamination, extend the service life of the equipment, and reduce the maintenance frequency.

[0046] Among them, the tensile sensors of multiple tensile testing mechanisms 2 are connected to the test display screen 17 via signal lines or wireless communication, transmitting tensile data to the display screen for centralized display in real time. The tensile data of each station is displayed centrally, making it convenient for operators to observe the results of all test stations simultaneously without having to check them one by one. Real-time data display helps to quickly determine whether the spoke X is qualified (such as whether the tensile value is within the preset range), shortening the time for judging test results and improving the overall testing efficiency.

[0047] Please refer to Figure 3Preferably, the tensile testing mechanism 2 further includes a position sensor 18, which is positioned near the second limiting unit 4. The position sensor 18 is signal-connected to the drive unit 5 to prevent the first limiting unit 3 from getting too close to the second limiting unit 4. Specifically, the position sensor 18 is installed near the second limiting unit 4. When the first limiting unit 3 moves close to the second limiting unit 4 with the slider, the sensor detects the position signal of the first limiting unit 3 and transmits the signal to the drive unit 5. The drive unit 5 then stops the motor, limiting the movement range of the first limiting unit 3.

[0048] The limit protection provided by the position sensor 18 prevents the first limit unit 3 from getting too close to the second limit unit 4. Furthermore, the reset stroke can be reduced according to the spoke X length. At the same time, the automatic stop function reduces the cost of manual monitoring and improves the safety of equipment operation.

[0049] Furthermore, the position sensor 18 is slidably mounted on the guide rail 14, and its detection position can be adjusted along the length of the guide rail 14. The position sensor 18 can be slidably mounted on the guide rail 14, and its detection position can be adjusted along the length of the guide rail 14. The trigger position can be flexibly adjusted according to the testing requirements of different spokes X. It can adapt to various testing scenarios without reinstalling or calibrating the equipment, further improving the versatility and flexibility of the equipment.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
