Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology and relates to a wheel rim testing device. Background Technology

[0002] After the spokes are welded, the rim needs to be inspected with a visual inspection instrument to check whether the weld seam is qualified. For the inspection principle of the rim, please refer to the rim weld airtightness testing device and airtightness testing method provided in application number 201811129848.9.

[0003] Due to the diversity of product sizes, general testing equipment cannot perform universal testing of rims or wheel rims of various sizes on the same machine. Different models of rollers need to be replaced according to different sizes of rims or wheel rims in order to achieve dynamic testing of rims or wheel rims, which is quite cumbersome.

[0004] It is evident that the existing detection devices are not highly adaptable. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a wheel rim inspection device. The technical problem this invention aims to solve is: how to inspect wheel rims of different sizes.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A wheel rim inspection device includes a base on which a visual inspection instrument for inspecting wheel rims is mounted. The device is characterized in that the base also includes an active roller, a driven roller one, a driven roller two, a driven roller three, and a drive mechanism for rotating the active roller, driven roller one, driven roller two, and driven roller three. The active roller and driven roller one are located above, and the driven roller two and driven roller three are located below. The distance between the active roller and driven roller one is greater than the distance between driven roller two and driven roller three.

[0008] Its working principle is:

[0009] Before starting the inspection, the wheel rim to be tested is placed in the wheel rim inspection device, the position of the vision inspection instrument is adjusted, and the drive mechanism drives the active roller, which in turn drives the driven roller one, driven roller two, and driven roller three to rotate synchronously. At this time, the four rollers rotate synchronously, and at least two of the active roller, driven roller one, driven roller two, and driven roller three are in contact with the wheel rim to be tested. They drive the wheel rim to be tested to rotate and perform defect detection of the weld.

[0010] In this wheel rim inspection device, the driving roller and driven roller one are located at the top, while driven roller two and driven roller three are located at the bottom. The distance between the driving roller and driven roller one is greater than the distance between driven roller two and driven roller three. When inspecting wheel rims of different sizes, two of the four rollers are always in contact with the rim of the wheel rim. The rollers in contact with the wheel rim drive the wheel rim to rotate, so that wheel rims of different sizes (generally 5 inches to 26 inches) can be inspected on this device, which greatly improves adaptability.

[0011] In the aforementioned wheel rim testing device, a fixed plate one and a fixed plate two are mounted on the base and are arranged opposite to each other. The driving roller, driven roller one, driven roller two, and driven roller three are rotatably mounted on the fixed plate one and the fixed plate two. The driving mechanism includes a motor and several synchronous pulleys. The motor is mounted on the base, and one output shaft of the motor is connected to one end of the driving roller. The synchronous pulleys are respectively mounted on the ends of driven roller one, driven roller two, and driven roller three, and a synchronous belt is tensioned between the synchronous pulleys.

[0012] In this structure, the motor drives the active roller to rotate, and the active roller drives the driven roller one, driven roller two, and driven roller three to rotate through the synchronous pulley and synchronous belt, so that the four rollers rotate synchronously. When the wheel rim is placed on the device and contacts two of the four rollers, the wheel rim can be driven to rotate, and the detection is completed by the vision inspection instrument.

[0013] In the aforementioned wheel rim testing device, a vertically extending strip groove is provided on the first fixing plate, and a connecting shaft that can move up and down and be positioned on the first fixing plate is provided on the strip groove. A clamping wheel is installed at the outer end of the connecting shaft, and the clamping wheel is pressed against the outside of the timing belt. A bolt is threadedly connected to the top of the first fixing plate, and the bolt thread abuts against the connecting shaft.

[0014] As one embodiment, a washer and a nut can be fitted onto the connecting shaft. The nut is threaded onto the connecting shaft, and the connecting shaft is clamped and fixed to the fixing plate by the nut and washer. When the nut is loosened, the bolt is rotated, and the bolt screw adjusts the vertical position of the connecting shaft, thereby adjusting the pressure of the pressure wheel on the timing belt. The tension between the timing belt and the timing wheel can be adjusted as needed, which greatly improves adaptability.

[0015] In the aforementioned wheel rim testing device, positioning blocks and stop blocks are respectively fitted on the driving roller, driven roller one, driven roller two, and driven roller three. Each positioning block is fixed on the driving roller, driven roller one, driven roller two, and driven roller three, and each stop block is movable and can be positioned on the driving roller, driven roller one, driven roller two, and driven roller three.

[0016] Positioning blocks and stops are installed on all four rollers. The positioning blocks and stops play a good role in positioning the wheel rim. The stops are movable. When it is necessary to change to a different size wheel rim for inspection, it is only necessary to adjust the position of the stop and then make fine adjustments to the vision inspection instrument.

[0017] In the aforementioned wheel rim inspection device, a guide rail is mounted on the base, a slider is slidably connected to the guide rail, a rotating arm is hinged to the slider, a bracket is mounted on the rotating arm, and the vision inspection instrument is mounted on the bracket.

[0018] The position of the visual inspection instrument can be adjusted left and right by moving the slider. After determining the left and right position of the visual inspection instrument, rotate the rotating arm to adjust the position of the visual inspection instrument within a small range so that the visual inspection instrument is aligned with the wheel being inspected until the visual inspection result is stable and accurate.

[0019] In the aforementioned wheel rim inspection device, the bracket includes a vertical rod, which is mounted on a rotating arm. A horizontal rod is mounted on the vertical rod, and a fixing clamp is mounted on the horizontal rod. The fixing clamp is movable and can be positioned on the vertical rod, and the vision inspection instrument is mounted on the horizontal rod.

[0020] As one embodiment, the fixing clip 1 is fixed to the vertical rod by the screw 1. Loosening the screw 1 allows the fixing clip 1 to move along the vertical rod, thereby adjusting the position of the vision inspection instrument in the height direction. After the position is adjusted, tightening the screw 1 can fix the fixing clip 1 to the vertical rod.

[0021] In the aforementioned wheel rim inspection device, a movable fixing clamp two is installed on the crossbar, a vertically extending connecting rod is installed on the fixing clamp two, a fixing clamp three is installed on the connecting rod, and the vision inspection instrument is installed on the fixing clamp three.

[0022] As one embodiment, the fixing clip two is fixed to the crossbar by the screw two. When the screw two is loosened, the fixing clip two can move along the crossbar, thereby adjusting the position of the vision inspection instrument in the front-back direction. After the position is adjusted, the screw two is tightened to fix the fixing clip two to the crossbar.

[0023] In the aforementioned wheel rim inspection device, a connector that can rotate and be positioned on the fixed clamp is mounted on the fixed clamp, and the vision inspection instrument is mounted on the connector.

[0024] As one embodiment, the connector is fixed to the fixing clamp three by screw three. Loosening screw three allows the connector to rotate relative to the fixing clamp three, thereby adjusting the angle of the vision inspection instrument so that the vision inspection instrument is aligned with the object being inspected, thus improving the accuracy of the inspection. After the angle is adjusted, screw three is tightened to fix the connector to the fixing clamp three.

[0025] The wheel rim testing device described above also includes an upper pressure block one and an upper pressure block two. The upper pressure block one is mounted on the slider. The rotating arm includes two parallel swing rods. The inner ends of the two swing rods are respectively hinged to the upper pressure block one, and the outer ends of the two swing rods are respectively hinged to the upper pressure block two.

[0026] The two swing arms of the rotating arm and the two upper pressure blocks form a parallelogram structure, making the rotating arm more stable and the rotation angle more precise. This ensures that the visual inspection instrument remains parallel to the spokes during fine adjustments, resulting in more accurate inspection results.

[0027] In the aforementioned wheel rim inspection device, there are two vision inspection instruments arranged opposite to each other, and the wheel rim can be placed between the two vision inspection instruments.

[0028] After the wheel rim is placed, one vision inspection instrument is located on one side of the wheel rim and another vision inspection instrument is located on the other side of the wheel rim. The two vision inspection instruments inspect the wheel rim, resulting in more stable inspection results and higher inspection efficiency.

[0029] Compared with the prior art, the advantages of the present invention are as follows:

[0030] 1. In this wheel rim inspection device, when inspecting wheel rims of different sizes, two of the four rollers are always in contact with the rim flange. The rollers in contact with the rim drive the rim to rotate, so that wheel rims of different sizes can be inspected, which greatly improves adaptability.

[0031] 2. In this wheel rim inspection device, the two swing arms of the rotating arm and the two upper pressure blocks form a parallelogram structure, which makes the rotating arm more stable when rotating and the rotation angle more precise. This ensures that the visual inspection instrument remains parallel to the spokes during fine adjustments, resulting in more accurate inspection results. Attached Figure Description

[0037] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] like Figure 1 As shown, this wheel rim inspection device includes a base 1, on which a vision inspection instrument 2 for inspecting wheel rims 33 is mounted. The base 1 also includes an active roller 3, a driven roller 1 4, a driven roller 2 5, a driven roller 3 6, and a drive mechanism 7 for rotating the active roller 3, driven roller 1 4, driven roller 2 5, and driven roller 3 6. The active roller 3 and driven roller 1 4 are located above, and the driven roller 2 5 and driven roller 3 6 are located below. The distance between the active roller 3 and driven roller 1 4 is greater than the distance between the driven roller 2 5 and driven roller 3 6.

[0039] like Figure 2 As shown, before starting the inspection, the wheel rim 33 to be tested is placed in the wheel rim inspection device, the position of the vision inspection instrument 2 is adjusted, and the drive mechanism 7 drives the active roller 3, which in turn drives the driven roller 4, driven roller 5, and driven roller 6 to rotate synchronously. At this time, the four rollers rotate synchronously, and at least two of the active roller 3, driven roller 4, driven roller 5, and driven roller 6 are in contact with the wheel rim 33 to be tested. They drive the wheel rim 33 to rotate to perform weld defect inspection.

[0040] In this wheel rim inspection device, the driving roller 3 and driven roller 1 4 are located at the top, and the driven roller 2 5 and driven roller 3 6 are located at the bottom. The distance between the driving roller 3 and driven roller 1 4 is greater than the distance between driven roller 2 5 and driven roller 3 6. When inspecting wheel rims 33 of different sizes, two of the four rollers are always in contact with the rim of the wheel rim 33. The rollers in contact with the wheel rim 33 drive the wheel rim 33 to rotate, so that wheel rims 33 of different sizes (generally 5 inches to 26 inches) can be inspected on this device, which greatly improves adaptability.

[0041] like Figure 1As shown, in this embodiment, a fixed plate 8 and a fixed plate 9 are installed on the base 1, which are arranged opposite to each other. The driving roller 3, the driven roller 4, the driven roller 5, and the driven roller 6 are rotatably installed on the fixed plate 8 and the fixed plate 9. The driving mechanism 7 includes a motor 10 and several synchronous pulleys 11. The motor 10 is installed on the base 1. One output shaft of the motor 10 is connected to one end of the driving roller 3. Synchronous pulleys 11 are respectively installed on the ends of the driven roller 4, the driven roller 5, and the driven roller 6. A synchronous belt 12 is tensioned between the synchronous pulleys 11.

[0042] In this structure, the motor 10 drives the active roller 3 to rotate. The active roller 3 drives the driven roller 4, driven roller 5 and driven roller 6 to rotate through the synchronous pulley 11 and the synchronous belt 12, so that the four rollers rotate synchronously. When the wheel rim 33 is placed on the device and contacts two of the four rollers, the wheel rim 33 can be driven to rotate, and the detection is completed by the vision inspection instrument 2.

[0043] like Figure 1 and 3 As shown, in this embodiment, a vertically extending strip groove 13 is provided on the fixing plate 8. A connecting shaft 14 that can move up and down and be positioned on the fixing plate 8 is provided on the strip groove 13. A pressure wheel 15 is installed at the outer end of the connecting shaft 14. The pressure wheel 15 presses against the outside of the timing belt 12. A bolt 16 is threadedly connected to the top of the fixing plate 8. The bolt 16 abuts against the connecting shaft 14.

[0044] As one embodiment, a washer and a nut can be fitted onto the connecting shaft 14. The nut is threaded onto the connecting shaft 14, and the connecting shaft 14 is clamped and fixed onto the fixing plate 8 by the nut and washer. When the nut is loosened, the bolt 16 is rotated, and the screw of the bolt 16 adjusts the vertical position of the connecting shaft 14, thereby adjusting the pressure of the pressure wheel 15 on the timing belt 12. The tension between the timing belt 12 and the timing wheel 11 can be adjusted as needed, which greatly improves adaptability.

[0045] like Figure 1 As shown in Figure 2, in this embodiment, positioning blocks 17 and stop blocks 18 are respectively fitted on the driving roller 3, driven roller 1 4, driven roller 2 5 and driven roller 3 6. Each positioning block 17 is fixed on the driving roller 3, driven roller 1 4, driven roller 2 5 and driven roller 3 6, and each stop block 18 is movable and can be positioned on the driving roller 3, driven roller 1 4, driven roller 2 5 and driven roller 3 6.

[0046] Positioning blocks 17 and stops 18 are installed on each of the four rollers. Positioning blocks 17 and stops 18 provide good positioning for the wheel rim 33. Stops 18 are movable. When it is necessary to change to a different size wheel rim 33 for inspection, it is only necessary to adjust the position of the stop 18 and then make fine adjustments to the vision inspection instrument 2.

[0047] like Figure 1 and 4 As shown, in this embodiment, a guide rail 19 is installed on the base 1, a slider 20 is slidably connected to the guide rail 19, a rotating arm 21 is hinged to the slider 20, a bracket 22 is installed on the rotating arm 21, and a vision inspection instrument 2 is installed on the bracket 22.

[0048] The position of the visual inspection instrument 2 can be adjusted in the left and right directions by moving the slider 20. After determining the left and right position of the visual inspection instrument 2, the rotating arm 21 is rotated to adjust the position of the visual inspection instrument 2 within a small range so that the visual inspection instrument 2 is aligned with the wheel rim 33 being inspected, until the visual inspection result is stable and accurate.

[0049] like Figure 4 As shown, in this embodiment, the bracket 22 includes a vertical rod 23, which is mounted on the rotating arm 21. A horizontal rod 24 is mounted on the vertical rod 23, and a fixing clamp 25 is mounted on the horizontal rod 24. The fixing clamp 25 is movable and can be positioned on the vertical rod 23. The vision inspection instrument 2 is mounted on the horizontal rod 24.

[0050] As one embodiment, the fixing clip 25 is fixed to the vertical rod 23 by screw 1. Loosening screw 1 allows the fixing clip 25 to move along the vertical rod 23, thereby adjusting the position of the vision inspection instrument 2 in the height direction. After the position is adjusted, tightening screw 1 can fix the fixing clip 25 to the vertical rod 23.

[0051] like Figure 4 As shown, in this embodiment, a movable fixing clamp 26 is installed on the crossbar 24, a vertically extending connecting rod 27 is installed on the fixing clamp 26, a fixing clamp 3 28 is installed on the connecting rod 27, and the vision inspection instrument 2 is installed on the fixing clamp 3 28.

[0052] As one embodiment, the second fixing clip 26 is fixed to the crossbar 24 by the second screw. When the second screw is loosened, the second fixing clip 26 can move along the crossbar 24, thereby adjusting the position of the vision inspection instrument 2 in the front-back direction. After the position is adjusted, the second screw is tightened to fix the second fixing clip 26 to the crossbar 24.

[0053] like Figure 4 As shown, in this embodiment, a connector 29 that can rotate and be positioned on the fixing clamp 28 is installed on the fixing clamp 28, and the vision inspection instrument 2 is installed on the connector 29.

[0054] As one embodiment, the connector 29 is fixed to the fixing clamp 28 by the screw three. When the screw three is loosened, the connector 29 can rotate relative to the fixing clamp 28, thereby adjusting the angle of the vision inspection instrument 2 so that the vision inspection instrument 2 is opposite to the object being inspected, thus improving the accuracy of the inspection. After the angle is adjusted, the screw three is tightened to fix the connector 29 to the fixing clamp 28.

[0055] like Figure 4 As shown, in this embodiment, it also includes an upper pressure block 30 and an upper pressure block 31. The upper pressure block 30 is mounted on the slider 20. The rotating arm 21 includes two parallel swing rods 32. The inner ends of the two swing rods 32 are respectively hinged to the upper pressure block 30, and the outer ends of the two swing rods 32 are respectively hinged to the upper pressure block 31.

[0056] The two swing arms 32 of the rotating arm 21 and the two upper pressure blocks form a parallelogram structure, making the rotating arm 21 more stable and the rotation angle more precise. This ensures that the visual inspection instrument 2 remains parallel to the spokes during fine adjustments, resulting in more accurate inspection results.

[0057] like Figure 1 As shown in Figure 2, in this embodiment, there are two vision inspection instruments 2 arranged opposite to each other, and the wheel rim 33 can be placed between the two vision inspection instruments 2.

[0058] After the wheel rim 33 is placed, one visual inspection instrument 2 is located on one side of the wheel rim 33, and another visual inspection instrument 2 is located on the other side of the wheel rim 33. The two visual inspection instruments 2 inspect the wheel rim 33, resulting in more stable inspection results and higher inspection efficiency.

[0059] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
