Description

Technical Field

[0001] This invention relates to the field of testing technology for transmission components, and in particular to a testing device and testing method. Background Technology

[0002] Universal balls, rollers, and other similar components are transmission parts commonly used in material conveying. When manufacturing these transmission parts, it is necessary to ensure that they can operate normally for a preset time under certain speeds and loads.

[0003] In the testing equipment for related technologies, two clamping blocks are used to clamp and fix the omnidirectional ball, and then the two clamping blocks are locked. Then, a certain load is applied to the omnidirectional ball through the test roller, and then the test roller is driven to rotate at a certain speed, thereby completing the test of the omnidirectional wheel.

[0004] However, due to the influence of error, after the clamping block is locked, there is still a certain gap between the clamping block and the universal ball. During the subsequent rotation of the test roller, the universal ball is prone to deviate due to the load applied by the test roller, thus affecting the test effect of the test equipment on the universal ball. Summary of the Invention

[0024] The following is for reference. Figures 1 to 4 The test equipment for the first aspect of this application will be described in detail.

[0025] refer to Figure 1 and Figure 2According to a first aspect of the present invention, the testing device includes a loading module 100, a testing module 200, and an adjustment module 300. The loading module 100 includes a mounting base 110, a clamping structure 120, a locking structure 130, and a plurality of loading structures 140. The plurality of loading structures 140 includes a first loading structure 140A and a second loading structure 140B spaced apart on the mounting base 110 along a first horizontal direction. Each of the first loading structure 140A and the second loading structure 140B has a loading groove 141a at one end close to the other. A clamping area 101 for clamping a universal ball is formed between the two loading grooves 141a. The first loading structure 140A... The first horizontal direction is movable. The locking structure 130 is connected to the mounting base 110 and the first loading structure 140A respectively, and is used to lock and fix the first loading structure 140A on the mounting base 110. The test module 200 includes a test roller 220 and a first drive structure 210. The test roller 220 is used to abut against the universal ball in the clamping area 101. The first drive structure 210 is driven to the test roller 220 and is used to drive the test roller 220 to rotate. The adjustment module 300 is connected to at least one of the loading module 100 and the test module 200, and is used to adjust the pressure between the test roller 220 and the universal ball in the clamping area 101.

[0026] Understandably, when the testing equipment tests the omnidirectional ball, the operator can place the omnidirectional ball in the clamping area 101. Then, the operator can drive the first loading structure 140A to approach the second loading structure 140B along the first horizontal direction, so that the groove wall of the loading groove 141a on the first loading structure 140A can cooperate with the groove wall of the loading groove 141a on the second loading structure 140B to clamp the omnidirectional ball, thereby locking and fixing the omnidirectional ball. Next, the operator can lock and fix the first loading structure 140A through the locking structure 130. Immediately afterwards, the adjusting module 300 can drive the loading module 100 and the testing module 200 to approach each other, so that the testing roller 220 and the omnidirectional ball come into contact and maintain a preset pressure between the testing roller 220 and the omnidirectional ball. Subsequently, the first driving structure 210 drives the testing roller 220 to rotate at a certain speed, thereby testing the omnidirectional ball.

[0027] Understandably, since the loading groove 141a is set in a V shape, the two loading grooves 141a can clamp the universal ball while the loading grooves 141a work together. The V-shaped structure of the loading groove 141a also allows the loading groove 141a to position the universal ball, thereby reducing the probability of the universal ball becoming misaligned during the testing process of the test roller 220.

[0028] It should be noted that when the test roller 220 tests the universal ball, a certain pressure needs to be maintained between the test roller 220 and the universal ball. After the operator pushes the first loading structure 140A to clamp the universal ball in conjunction with the second loading structure 140B, due to the influence of error, there will still be a large gap between the universal ball and the groove wall of the loading groove 141a. The existence of these gaps will cause the universal ball to be significantly misaligned during the process of the test roller 220 squeezing the universal ball, thus affecting the test results of the test equipment on the universal ball.

[0029] Based on the above problems, in the test equipment of this application, reference is made to Figure 2 The loading module 100 also includes a clamping structure 120, which is connected to the mounting base 110 and the first loading structure 140A respectively, and can push the first loading structure 140A closer to the clamping area 101.

[0030] Furthermore, after the operator pushes the first loading structure 140A closer to the second loading structure 140B along the first horizontal direction so that the first loading structure 140A cooperates with the second loading structure 140B to clamp the universal ball in the clamping area 101, the operator can push the first loading structure 140A further closer to the second loading structure 140B through the pressing structure 120 so that the first loading structure 140A and the second loading structure 140B can further clamp the universal ball in the clamping area 101. After the locking structure 130 locks and fixes the first loading structure 140A, the gap between the universal ball and the groove wall of the loading groove 141a can be smaller, so that when the test roller 220 tests the universal ball, the deviation generated by the universal ball can be smaller, so as to accurately test the universal ball by the testing equipment of this application.

[0031] Preferably, in order to improve the limiting effect of the loading groove 141a on the universal ball, the loading groove 141a is set to V-shape.

[0032] In some embodiments of the present invention, reference is made to Figure 2 The mounting base 110 is provided with a slide rail 111 extending along the first horizontal direction, and the first loading structure 140A is slidably disposed on the slide rail 111; the clamping structure 120 includes an adjusting screw 121 and a baffle 122. The adjusting screw 121 extends along the first horizontal direction, is threadedly connected to the mounting base 110, and is rotatably connected to the baffle 122. The baffle 122 is detachably connected to the first loading structure 140A.

[0033] Then, by rotating the adjusting screw 121, the operator can push the first loading structure 140A along the slide rail 111 to approach the second loading structure 140B through the baffle 122, so that the first loading structure 140A cooperates with the second loading structure 140B to clamp the universal ball in the clamping area 101.

[0034] It is understandable that, since the adjusting screw 121 is rotatably connected to the baffle 122 and the baffle 122 is detachably connected to the first loading structure 140A, the operator can achieve the connection between the pressing structure 120 and the first loading structure 140A by connecting the baffle 122 and the first loading structure 140A. At the same time, compared with directly rotatably connecting the screw to the first loading structure 140A, the baffle 122 in this application reduces the installation difficulty between the pressing structure 120 and the first loading structure 140A and facilitates the replacement of the pressing structure 120 or the first loading structure 140A.

[0035] Specifically, the baffle 122 and the first loading structure 140A are connected by screws or other connecting parts.

[0036] Understandably, with the slide rail 111 in place, the first loading structure 140A can slide accurately along the first horizontal direction.

[0037] Specifically, the locking structure 130 is a locking bolt, which passes through the first loading structure 140A and abuts against the mounting base 110.

[0038] Understandably, when the worker tightens the locking bolt so that it abuts against the mounting base 110, sufficient friction is generated between the locking bolt and the mounting base 110 to prevent the first loading structure 140A from moving in the first horizontal direction. When the worker loosens the locking bolt so that it moves away from the mounting base 110, the worker can then smoothly drive the first loading structure 140A to move in the first horizontal direction.

[0039] To further improve the stability of the first loading structure 140A in the first horizontal direction, in some other embodiments of the present invention, two slide rails 111 are arranged side by side, and the first loading structure 140A is slidably connected to the two slide rails 111 respectively.

[0040] To achieve a rotatable connection between the adjusting screw 121 and the baffle 122, in some embodiments of the present invention, reference is made to... Figure 3The clamping structure 120 also includes a first threaded connector 123, which includes a head and a rod connected to each other. The rod is rotatably inserted through the baffle 122 and threadedly connected to the end of the adjusting screw 121. The head abuts against the end of the baffle 122 away from the adjusting screw 121.

[0041] Furthermore, by passing the rod of the first threaded connector 123 through the baffle 122 and threading the rod to the adjusting screw 121, the operator can achieve a rotatable connection between the adjusting screw 121 and the baffle 122; by unscrewing the first threaded connector 123 out of the adjusting screw 121, the operator can disassemble the adjusting screw 121 and the baffle 122.

[0042] It is understandable that the first threaded connector 123 not only enables the rotatable connection between the adjusting screw 121 and the baffle 122, but also facilitates the disassembly of the adjusting screw 121 and the baffle 122.

[0043] It should be noted that during the rotation of the adjusting screw 121, there is a problem that the adjusting screw 121 and the first threaded connector 123 rotate relative to each other. At this time, the first threaded connector 123 is easy to detach from the adjusting screw 121.

[0044] Based on the above problems, in a further embodiment of the present invention, adhesive is used to fill the space between the rod portion of the first threaded connector 123 and the adjusting screw 121. It is understood that the adhesive can further enhance the connection strength between the rod portion and the adjusting screw 121, thereby reducing the probability of relative rotation between the rod portion and the adjusting screw 121, and thus reducing the probability of thread loosening between the rod portion and the adjusting screw 121.

[0045] In some embodiments of the present invention, reference is made to Figure 4 The loading structure 140 includes a first loading seat 141 and a second loading seat 142. The second loading seat 142 is mounted on the first loading seat 141. A loading groove 141a is formed on the first loading seat 141. The second loading seat 142 is provided with a loading hole 142a, which allows one end of the roller to pass through.

[0046] It is understood that when the omnidirectional ball needs to be tested, the omnidirectional ball can be clamped in the clamping area 101 between the two first loading seats 141; when the roller needs to be tested, the roller axle can be respectively inserted into the loading holes 142a of the two second loading seats 142; the arrangement of the first loading seats 141 and the second loading seats 142 enables the testing equipment of this application to not only complete the testing of the omnidirectional ball, but also the testing of the roller, thereby improving the versatility of the testing equipment of this application.

[0047] It should be noted that the test roller 220 is located above the loading module 100, and the adjustment module 300 can drive the loading module 100 to move closer to or further away from the test roller 220 in the vertical direction. Correspondingly, in order for the test roller 220 to stably abut against the universal ball in the clamping area 101, the clamping area 101 is located directly below the test roller 220. In order for the roller to stably abut against the test roller 220 during testing, the loading hole 142a needs to be aligned with the loading groove 141a in the second horizontal direction. However, when the loading hole 142a is aligned with the loading groove 141a in the second horizontal direction, although the test roller 220 can successfully complete the roller test, when the test roller 220 needs to test the universal ball in the clamping area 101, the second loading seat 142 will interfere with the test roller 220, making it difficult for the test roller 220 to smoothly abut against the universal ball.

[0048] Based on the above problems, in some embodiments of the present invention, reference is made to Figure 4 The second loading seat 142 is adjustablely positioned on the first loading seat 141 along the second horizontal direction, and the second horizontal direction is set at a certain angle from the first horizontal direction.

[0049] Understandably, when the testing equipment of this application needs to test the roller, the operator can adjust the position of the second loading seat 142 along the second horizontal direction so that the second loading seat 142 is aligned with the test roller 220 in the second horizontal direction. At this time, after the roller is loaded into the loading hole 142a, the roller can be located directly below the test roller 220, and the test roller 220 can successfully complete the test of the roller. When the testing equipment of this application needs to test the universal wheel, the operator can adjust the position of the second loading seat 142 along the second horizontal direction so that the second loading seat 142 is offset from the test roller 220 in the second horizontal direction, thereby reducing the interference of the second loading seat 142 on the test roller 220 during the test of the universal wheel, so that the test roller 220 can successfully complete the test of the universal wheel.

[0050] In order to achieve accurate movement of the second loading seat 142 in the second horizontal direction, in a further embodiment of the present invention, reference is made to... Figure 4 The first loading seat 141 is provided with a groove 141b extending along the second horizontal direction, and the second loading seat 142 is provided with an insertion hole 142b. A second threaded connector is inserted into the insertion hole 142b and is used to abut against the groove wall of the groove 141b.

[0051] Furthermore, when the operator needs to adjust the position of the second loading seat 142 in the second horizontal direction, the operator can first loosen the second threaded connector, and then drive the second loading seat 142 to slide along the slide groove 141b in the second horizontal direction to move the second loading seat 142 to a preset position. Then, the operator can tighten the second threaded connector, which abuts against the groove wall of the slide groove 141b, thereby generating a frictional force that resists the second loading seat 142, so as to fix the second loading seat 142 on the first loading seat 141, thereby completing the position adjustment of the second loading seat 142 in the second horizontal direction.

[0052] Understandably, the design of the slide 141b allows for more precise position adjustment of the second loading seat 142 in the second horizontal direction.

[0053] Furthermore, in order to reduce the probability of the second loading seat 142 disengaging from the slide 141b, the slide 141b is configured as a T-shape.

[0054] In some embodiments of the present invention, reference is made to Figure 1 The adjustment module 300 includes a mounting frame 310, a sensor 320, and a second drive structure 330. The mounting base 110 is slidably mounted on the mounting frame 310 in the vertical direction, and the test roller 220 is rotatably mounted on the mounting frame 310. The second drive structure 330 is drivenly connected to the mounting base 110 through the sensor 320 and is used to drive the mounting base 110 to perform lifting and lowering movements. The sensor 320 is used to detect the load between the second drive structure 330 and the mounting base 110.

[0055] Understandably, when testing the omnidirectional ball, the mounting base 110 can move upward under the drive of the second drive structure 330, so that the omnidirectional ball in the clamping area 101 comes into contact with the test roller 220. Then, the first drive structure 210 can drive the test roller 220 to rotate. During the rotation of the test roller 220, it can drive the omnidirectional ball to rotate. During this process, the load between the second drive structure 330 and the mounting base 110 detected by the sensor 320 is the load between the omnidirectional ball and the test roller 220. Based on the load detected by the sensor 320, the operator can indirectly understand the quality of the omnidirectional ball.

[0056] It should be noted that during the rotation of the universal ball driven by the test roller 220, the universal ball will generate a certain vibration. Correspondingly, the mounting base 110 will also generate a certain vibration under the drive of the universal ball. These vibrations will affect the accuracy of the detection results of the sensor 320.

[0057] To improve the accuracy of the detection results of sensor 320, in some embodiments of the present invention, reference is made to... Figure 1The adjustment module 300 also includes an elastic buffer 340 and a mounting plate 350. The mounting plate 350 is slidably mounted on the mounting frame 310 in the vertical direction. The upper and lower ends of the elastic buffer 340 are connected to the mounting base 110 and the mounting plate 350, respectively. The sensor 320 is mounted on the mounting plate 350, and the detection end of the sensor 320 is connected to the output end of the second drive structure 330.

[0058] Understandably, by setting an elastic buffer 340 between the sensor 320 and the mounting base 110, the vibration generated by the omnidirectional ball during rotation can have a smaller impact on the sensor 320 under the action of the elastic buffer 340, thereby making the detection results of the sensor 320 more accurate.

[0059] In some embodiments of the present invention, reference is made to Figure 1 The adjustment module 300 also includes a display 360, which is electrically connected to the sensor 320 and is used to display the detection results of the sensor 320.

[0060] Understandably, the 360-degree display allows staff to more intuitively understand the detection results of the 320 sensor.

[0061] In some embodiments of the present invention, the first drive structure 210 includes a motor and a transmission belt. The output end of the motor is connected to the test roller 220 via the transmission belt, so that the motor can drive the test roller 220 to rotate via the transmission belt.

[0062] In some embodiments of the present invention, the second driving structure 330 is a jack, which is easy to obtain and inexpensive.

[0063] The following is for reference. Figure 5 The test method of the second aspect of the present invention will be described in detail.

[0064] The testing method provided in the second aspect of the present invention is applied to the testing equipment provided in the first aspect of the present invention; see reference. Figure 5 The testing method includes, but is not limited to, the following steps: Step S100: Place the omnidirectional ball in the clamping area 101 and clamp the omnidirectional ball through the first loading structure 140A and the second loading structure 140B; Step S200: The first loading structure 140A is pushed closer to the second loading structure 140B in the first horizontal direction by the clamping structure 120, so that the first loading structure 140A cooperates with the second loading structure 140B to further clamp the universal ball. Step S300: The first loading structure 140A is locked and fixed on the mounting base 110 by the locking structure 130; Step S400: Adjust the pressure between the universal ball and the test roller 220 by adjusting the module 300 until the pressure between the universal ball and the test roller 220 reaches the preset value; Step S500: Drive the test roller 220 to rotate at a preset speed for a preset time through the first drive structure 210 to complete the test of the omnidirectional ball.

[0065] Understandably, the universal ball is first placed in the clamping area 101 and clamped by the first loading structure 140A and the second loading structure 140B. Then, the first loading structure 140A is pushed closer to the second loading structure 140B in the first horizontal direction by the pressing structure 120, so that the first loading structure 140A cooperates with the second loading structure 140B to further clamp the universal ball. Then, the first loading structure 140A is locked and fixed on the mounting base 110 by the locking structure 130. Next, the pressure between the universal ball and the test roller 220 is adjusted by the adjusting module 300 until the pressure between the universal ball and the test roller 220 reaches a preset value. Then, the test roller 220 is driven by the first driving structure 210 to rotate at a preset speed for a preset time to complete the test of the universal ball. After the first loading structure 140A and the second loading structure 140B clamp the universal ball, the clamping structure 120 pushes the first loading structure 140A to cooperate with the second loading structure 140B to further clamp the universal ball, which can further reduce the gap between the universal ball and the wall of the loading groove 141a, thereby making the displacement of the universal ball during the test smaller and improving the test effect of the universal ball.
