[0039] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0040] Please see Figures 1-9 The present invention provides a technical solution: a universal testing system and method for abrasive belts, comprising a base 8, a worktable 1, a tension roller 2, a vision inspection mechanism, and a friction mechanism.

[0041] The workbench 1 is set on the upper side of the base 8. A pair of tension rollers 2 are provided. The pair of tension rollers 2 are set on the workbench 1 in a relatively movable manner. The pair of tension rollers 2 tension the sand belt body 6 to be tested.

[0042] A pair of side plates 5 are fixedly connected to the upper end of the workbench 1. The vision inspection mechanism and the friction mechanism are respectively set inside the pair of side plates 5. The friction mechanism is used to perform wear test on the sanding belt body 6, and the vision inspection mechanism records the surface wear of the sanding belt body 6.

[0043] A central shaft 201 is fixedly connected to the inner side of the tension roller 2. A pair of displacement grooves 101 are provided at the upper end of the worktable 1. The central shaft 201 passes through the displacement grooves 101 and moves along them. A fixed cavity 102 is fixedly connected to the lower end of the worktable 1. A movable bottom groove is provided on the inner side of the fixed cavity 102. The lower end of the central shaft 201 extends into the movable bottom groove and moves along it. A central rotating rod 103 is rotatably connected to the center of the fixed cavity 102. A first torsion bar 104 is fixedly connected to the outer side of the central rotating rod 103. A pair of hinge rods 105 are rotatably connected to both ends of the first torsion bar 104. Arc-shaped sliding grooves are provided on the lower end surface of the worktable 1 and inside the fixed cavity 102. The upper and lower ends of the hinge rods 105 move along the arc-shaped sliding grooves. A second torsion bar 106 is provided between the hinge rods 105 and the central shaft 201 and is rotatably connected to them.

[0044] The friction mechanism includes a friction block 501, which is driven to move by an electric telescopic rod 502. The visual inspection mechanism includes a camera assembly 503.

[0045] First, the sanding belt body 6 to be tested is manually fitted onto the outside of a pair of tensioning rollers 2. Then, the rotation of the central rotating rod 103 drives the first torsion bar 104 to rotate. The first torsion bar 104 drives a pair of hinge rods 105 to move relative to each other along the arc-shaped slide groove, thereby pushing the second torsion bar 106, which drives a pair of central shafts 201 to move relative to each other along the displacement groove 101, so that a pair of tensioning rollers 2 tension the sanding belt body 6. It can be used to tension sanding belt bodies 6 of various lengths and has strong versatility.

[0046] Next, the tension roller 2 rotates to drive the sanding belt body 6 to maintain its motion. Then, the electric telescopic rod 502 drives the friction block 501 to move, so that the friction block 501 contacts the tensioned and moving sanding belt body 6, allowing the friction block 501 to perform a wear test on the sanding belt body 6. Then, the camera assembly 503 records the surface wear of the sanding belt body 6 after the wear test and compares it with the standard wear value. If the wear degree is too high than the standard value, it means that the wear resistance of the sanding belt body 6 is unqualified, otherwise it is qualified.

[0047] Gear 1 202 is rotatably connected to the upper side of the fixed cavity 102. The central rotating rod 103 passes through gear 1 202 and is rotatably connected to it. A pair of gears 203 are meshed at both ends of gear 1 202. The hinge rod 105 passes through gear 2 203 and is rotatably connected to it. Gear 3 204 is meshed on one side of gear 2 203. The central shaft 201 passes through gear 3 204 and is fixedly connected to it.

[0048] Preferably, when it is necessary to drive the tensioned abrasive belt body 6 to move, a gear 1 202 is provided. Specifically, the rotation of gear 1 202 drives a pair of gears 203 to rotate, and gears 203 drive gears 3 204 to rotate, which in turn drives the central shaft 201 and the tensioning roller 2 to rotate, thus driving the abrasive belt body 6 to move. Since the lengths of the first torsion bar 104 and the second torsion bar 106 are constant, the distances between gear 1 202 and gears 203, and between gears 203 and gears 3 204, are also constant. Therefore, it can be ensured that after the positions of several gears are adjusted, they still maintain a stable meshing state, thereby ensuring the stability of the transmission. This method can be used to tension abrasive belt bodies 6 of various sizes and drive them to move, making it highly practical.

[0049] The lower end of gear 102 is fixedly connected to a drive sleeve 107. A central rotating rod 103 passes through the drive sleeve 107 and is rotatably connected to it. The drive sleeve 107 passes through the fixed cavity 102 and is rotatably connected to it. The central rotating rod 103 extends to the lower side of the drive sleeve 107. Both the drive sleeve 107 and the central rotating rod 103 are driven to rotate by the drive assembly.

[0050] Preferably, when it is necessary for a pair of tensioning rollers 2 to tension the sanding belt body 6, the drive assembly drives the central rotating rod 103 to rotate, thereby driving the first torsion bar 104 to rotate, which in turn drives the pair of tensioning rollers 2 to tension the sanding belt. Then, when it is necessary to drive the tensioning rollers 2 to rotate, the drive assembly drives the drive sleeve 107 to rotate, and the drive sleeve 107 drives the gear 202 to rotate, which in turn drives the tensioning rollers 2 to rotate, causing the sanding belt body 6 to move.

[0051] The drive assembly includes a rotating disk 3, with several guide telescopic rods 301 on the upper side of the rotating disk 3. The guide telescopic rods 301 are connected to the drive sleeve 107. A central rotating rod 103 passes through the rotating disk 3 and is fitted with it with a clearance. A straight groove is opened at the lower end of the central rotating rod 103, and a pair of limiting rods 108 are provided in the straight groove. The limiting rods 108 are fixedly connected to the rotating disk 3.

[0052] Preferably, in the initial state, the limiting rod 108 is located at the upper inner side of the straight groove. When it is necessary to drive the rotating rod 103 to rotate, the rotating disk 3 drives a pair of limiting rods 108 to rotate. The limiting rods 108 are locked in the straight groove, which drives the rotating rod 103 to rotate, thereby driving a pair of tensioning rollers 2 to perform tensioning. At the same time, the rotating disk 3 also drives the driving sleeve 107 to rotate through the guide telescopic rod 301, thereby driving the tensioning rollers 2 to rotate slowly, without affecting the tensioning work of the sand belt body 6.

[0053] Next, after the sanding belt body 6 is tensioned, it needs to be driven to move. At this time, the rotating disk 3 descends, so that the limit rod 108 is disengaged from the straight groove. Then the rotating disk 3 rotates again, which can drive the drive sleeve 107 to rotate independently, thereby driving the tensioning roller 2 to rotate, so that the sanding belt body 6 can move and the testing work can begin.

[0054] When the inspection is completed and the sanding belt body 6 needs to be removed, the rotating disk 3 rises and resets, causing the limit rod 108 to re-engage in the straight groove. Then the rotating disk 3 rotates in the opposite direction, thereby driving the central rotating rod 103 to reverse, which resets the pair of tensioning rollers 2, allowing the operator to remove the sanding belt body 6.

[0055] The upper end of the transfer rod 103 passes through the workbench 1 and is rotatably connected to it. An annular groove 110 is provided on the upper side of the transfer rod 103. A pair of clamping plates 111 are provided on the upper side of the annular groove 110. The clamping plates 111 are adapted to the annular groove 110. The lower end of the clamping plates 111 is provided with a rounded chamfer. The upper end of the clamping plates 111 is fixedly connected to a top cover 112. Guide telescopic columns are provided at both ends of the top cover 112. The guide telescopic columns are connected to the workbench 1.

[0056] Preferably, when the limiting rod 108 disengages from the straight groove and begins to drive the sanding belt body 6 to move, the transfer rod 103 loses its power restriction, and thus cannot keep the pair of tensioning rollers 2 in a tensioned state. Therefore, an annular groove 110 and a clamping plate 111 are provided. Specifically, before the limiting rod 108 disengages from the straight groove, the top cover 112 moves down, causing the pair of clamping plates 111 to be engaged in the annular groove 110, thereby fixing the position of the transfer rod 103 and preventing it from deflecting. When the limiting rod 108 disengages from the straight groove, the position of the tensioning rollers 2 can be kept still, maintaining the current tensioned state and improving stability.

[0057] Preferably, the lower end of the card plate 111 is provided with a rounded chamfer, thereby increasing the fault tolerance rate when it is inserted into the annular card slot 110.

[0058] The inner side of the transfer rod 103 is connected to a central rod 109 with clearance fit. The lower end of the central rod 109 is fixedly connected to a pair of limiting rods 108. The upper end of the central rod 109 is rotatably connected to the top cover 112. After the card plate 111 and the annular card groove 110 are engaged with each other, the limiting rod 108 is disengaged from the straight groove.

[0059] Preferably, a center rod 109 is provided on the inner side of the transfer rod 103. Specifically, after the rotating disk 3 drives a pair of tensioning rollers 2 to complete the tensioning of the sanding belt body 6, the rotating disk 3 descends, causing the limiting rod 108 to disengage from the straight groove. At this time, the limiting rod 108 drives the center rod 109 to move downward, thereby causing the top cover 112 to move downward, so that the clamping plate 111 first engages in the annular clamping groove 110 and locks it. Then, the limiting rod 108 completely disengages from the straight groove, and the rotating disk 3 can drive the sanding belt body 6 to move. In other words, the top cover 112 can be moved downward synchronously by the downward movement of the rotating disk 3. Before the transfer rod 103 loses its power restriction, the clamping plate 111 locks it, which has strong stability. When the rotating disk 3 rises and resets, the top cover 112 also rises synchronously, releasing the locking of the transfer rod 103. The limiting rod 108 can then drive the transfer rod 103 to reverse and release the sanding belt body 6, which has good synchronization.

[0060] The lower end of the transfer rod 103 is provided with a pair of adaptation slots. The adaptation slots are adjacent to and staggered with the straight slots. A spring telescopic rod is provided in the adaptation slot. One end of the spring telescopic rod is provided with an arc-shaped inclined block 113. The adaptation slot is used to accommodate the arc-shaped inclined block 113.

[0061] Preferably, when the inspection is completed and the sanding belt body 6 needs to be relaxed, the rotating disk 3 needs to rise and reset. In order to accurately align the limiting rod 108 with the straight groove, an arc-shaped inclined block 113 is provided. Specifically, when driving the sanding belt body 6 to move, the rotating disk 3 rotates, causing the limiting rod 108 to rotate. At this time, the limiting rod 108 moves along the inclined surface of the arc-shaped inclined block 113, thereby pressing it into the adaptation groove to avoid interference with the normal rotation of the rotating disk 3. When the rotating disk 3 needs to rise and reset, the rotating disk 3 reverses, so that the limiting rod 108 contacts the straight surface of the arc-shaped inclined block 113. The adaptation groove and the straight groove are adjacent and staggered, thereby automatically aligning the position of the limiting rod 108 with the straight groove. At this time, the rotating disk 3 can rise, so that the limiting rod 108 returns to the straight groove, which is highly practical.

[0062] The lower end of the fixed cavity 102 is rotatably connected to a rotating cover 4. The inner side of the rotating cover 4 is provided with an internal thread. The inner side of the base 8 is provided with a motor component 801, which is used to drive the rotating cover 4. The inner side of the rotating cover 4 is threadedly connected to the rotating disk 3.

[0063] Preferably, the inner side of the rotating cover 4 is threadedly connected to the rotating disk 3, and there is a certain friction between them. That is to say, due to the existence of friction, the rotating cover 4 will not easily drive the rotating disk 3 to rise or fall under normal conditions. When the rotating cover 4 is driven to rotate by the motor component 801, it drives the rotating disk 3 to rotate synchronously. At this time, the rotating disk 3 drives the central rotating rod 103 to rotate, thereby driving a pair of tensioning rollers 2 to tension the sanding belt body 6. After tensioning, the rotating cover 4 continues to rotate. Since the tensioning rollers 2 can no longer move, that is, the central rotating rod 103 and the rotating disk 3 can no longer rotate, thus remaining fixed. When the rotation driving force is greater than the above-mentioned friction, the rotating cover 4 relative to the rotating disk 3... The rotation is achieved through a threaded connection, and the limiting rod 108 guides the displacement along the straight groove, driving the rotating disk 3 to descend. This causes the clamping plate 111 to lock the central rod 103. After the limiting rod 108 disengages from the straight groove, the rotating disk 3 can continue to rotate. At this time, the rotating cover 4 drives the rotating disk 3 to rotate again through friction, which in turn drives the drive sleeve 107 to rotate independently, driving the sanding belt body 6 to move. In other words, by driving the rotating cover 4 alone, the tensioning roller 2 can be driven to complete the tensioning first, and then the rotation of the tensioning roller 2 can be automatically adjusted to make the sanding belt body 6 move. The degree of automation is high, and no additional drive components or control programs are required for control, saving costs.

[0064] When a reset is required, the rotating disk 3 reverses, causing the limiting rod 108 to align with the position of the straight groove. At this time, the limiting rod 108 is restricted by the arc-shaped inclined block 113, preventing the rotating disk 3 from continuing to reverse. When the rotational driving force is greater than the frictional force, the rotating cover 4 can drive the rotating disk 3 to rise, causing the limiting rod 108 to reset into the straight groove. The clamping plate 111 also disengages from the annular clamping groove 110, which can then re-drive the central rotating rod 103 to reverse, thereby releasing the sanding belt body 6.
