Description

Technical Field

[0001] The invention relates to the technical field of abrasive belts, and in particular to a universal abrasive belt testing system and a testing method thereof. Background Art

[0002] Abrasive belts are coated abrasives, also known as flexible abrasives. They are more flexible and safer than solid abrasive wheels when polishing, with higher precision and lower grinding costs. However, there are more and more abrasive belt manufacturers, and they have different requirements for the manufacturing quality of abrasive belts, resulting in deviations in the wear resistance of each abrasive belt. Some abrasive belts even do not meet national standards. Therefore, random inspections of the wear resistance of abrasive belts are particularly important. In addition to visual inspections, the quality inspection of abrasive belts also requires professional machines to simulate daily use. Therefore, it is necessary to use machines to scientifically test the wear resistance of abrasive belts. Existing testing devices do not fully test the wear resistance except for simple manual testing. At the same time, the abrasive belt wear resistance testing process lacks the fixation of the abrasive belt and other aspects of the friction and wear resistance of the abrasive belt, resulting in inaccurate test results.

[0003] The existing patent announcement number CN116659916B discloses a wear resistance detection device for an abrasive belt, comprising a base and a rotating barrel, a first roller clamp is arranged on the inner side of the rotating barrel, a second roller clamp is arranged on the inner side of the rotating barrel, a supporting rib is arranged on the outer side of the rotating barrel, a fixing plate is fixedly installed inside the rotating barrel, a push rod motor is fixedly installed above the fixing plate, an extension rod is arranged above the push rod motor, a supporting bin is fixedly installed above the extension rod, a first connecting piece is connected to the upper bearing of the supporting bin, a second connecting piece is connected to the upper bearing of the supporting bin, a clamping block is connected to the upper bearings of the first and second connecting pieces, a second cylinder is connected to the right bearing of the clamping block, a second gas rod is slidably connected to the inside of the second cylinder, and a second spring is welded to the right side of the second cylinder.

[0004] In the above technical solution, the two ends of the sandpaper are clamped and fixed by a clamping mechanism, and the sandpaper wrapped on the rotating barrel is reasonably straightened and tensioned and fixed by a push rod motor. However, this method can only tension and fix sandpaper of a fixed size, and has poor versatility.

[0040] See also Figure 1-9 The present invention provides a technical solution: a universal testing system for abrasive belts and a testing method thereof, comprising a base 8, a workbench 1, a tensioning roller 2, a visual detection mechanism and a friction mechanism.

[0041] The workbench 1 is arranged on the upper side of the base 8, and a pair of tensioning rollers 2 are arranged on the workbench 1 so as to be relatively movable, and the pair of tensioning rollers 2 tension the abrasive belt body 6 to be tested;

[0042] A pair of side plates 5 are fixedly connected to the upper end of the workbench 1. A visual inspection mechanism and a friction mechanism are respectively arranged on the inner side of the pair of side plates 5. The friction mechanism is used to perform a wear test on the abrasive belt body 6. The visual inspection mechanism records the surface wear of the abrasive belt body 6 in an image.

[0043] The inner side of the tensioning roller 2 is fixedly connected with a central axis 201, a pair of displacement grooves 101 are provided at the upper end of the workbench 1, the central axis 201 passes through the displacement grooves 101 and moves along them, the lower end of the workbench 1 is fixedly connected with a fixed cavity 102, a movable bottom groove is provided on the inner side of the fixed cavity 102, the lower end of the central axis 201 extends into the movable bottom groove and moves along it, the center of the fixed cavity 102 is rotatably connected with a transfer rod 103, the outer side of the transfer rod 103 is fixedly connected with a first torsion bar 104, and the two ends of the first torsion bar 104 are rotatably connected with a pair of hinge rods 105 respectively, the lower end surface of the workbench 1 and the fixed cavity 102 are both provided with arc-shaped slide grooves, the upper and lower ends of the hinge rod 105 move along the arc-shaped slide grooves, and a second torsion bar 106 is provided between the hinge rod 105 and the central axis 201 and is rotatably connected thereto;

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

[0045] First, the sand belt body 6 to be tested is manually sleeved on the outside of a pair of tensioning rollers 2; then, the transfer rod 103 is rotated to drive the first torsion bar 104 to rotate, and the first torsion bar 104 drives a pair of hinge rods 105 to relatively move along the arc-shaped slide groove, thereby pushing the second torsion bar 106, driving a pair of central shafts 201 to relatively move along the displacement groove 101, so that a pair of tensioning rollers 2 tension the sand belt body 6, and can be used for tensioning sand belt bodies 6 of various lengths, with strong versatility;

[0046] Then, the tensioning roller 2 rotates to drive the sanding belt body 6 to keep in motion, and 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, so that the friction block 501 performs a wear test on the sanding belt body 6; the camera component 503 is then used to record the image of the surface wear of the sanding belt body 6 after the wear test, and by comparing it with the standard wear value, if the wear degree is too higher than the standard value, it means that the wear resistance of the sanding belt body 6 is unqualified, otherwise it is qualified.

[0047] The upper side of the fixed cavity 102 is rotatably connected to gear 1 202, the transfer rod 103 passes through gear 1 202 and is rotatably connected thereto, a pair of gear 2 203 are meshedly connected at both ends of gear 1 202, the hinge rod 105 passes through gear 2 203 and is rotatably connected thereto, one side of gear 2 203 is meshedly connected to gear 3 204, and the center axis 201 passes through gear 3 204 and is fixedly connected thereto.

[0048] Preferably, when it is necessary to drive the belt body 6 to move after tensioning, a gear 1 202 is provided. Specifically, the rotation of the gear 1 202 drives a pair of gear 2 203 to rotate, and the gear 2 203 drives the gear 3 204 to rotate, thereby driving the central shaft 201 and the tensioning roller 2 to rotate, and driving the 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 the gear 1 202 and the gear 2 203, and between the gear 2 203 and the gear 3 204 are also constant. Therefore, it can be ensured that after the positions of the gears are adjusted, a stable meshing state is maintained, thereby ensuring the stability of the transmission. After tensioning the belt bodies 6 of various sizes, the belts 6 can be driven to move, which is highly practical.

[0049] The lower end of gear 1 202 is fixedly connected with a driving sleeve 107, the transfer rod 103 passes through the driving sleeve 107 and is rotatably connected thereto, the driving sleeve 107 passes through the fixed cavity 102 and is rotatably connected thereto, the transfer rod 103 extends to the lower side of the driving sleeve 107, and the driving sleeve 107 and the transfer rod 103 are both driven to rotate by the driving assembly.

[0050] Preferably, when it is necessary to make a pair of tensioning rollers 2 tension the sand belt body 6, the transfer rod 103 is driven to rotate through the driving assembly, thereby driving the first torsion bar 104 to rotate, and the pair of tensioning rollers 2 are driven to tension the sand belt. Then, when it is necessary to drive the tensioning roller 2 to rotate, the driving sleeve 107 is driven to rotate through the driving assembly, and the driving sleeve 107 drives the gear 1 202 to rotate, thereby driving the tensioning roller 2 to rotate, so that the sand belt body 6 moves.

[0051] The driving assembly includes a rotating disk 3, and a plurality of guide telescopic rods 301 are arranged on the upper side of the rotating disk 3. The guide telescopic rods 301 are connected to the driving sleeve 107. The transfer rod 103 passes through the rotating disk 3 and is clearance-matched with it. A straight groove is opened at the lower end of the transfer rod 103, and a pair of limit rods 108 are arranged in the straight groove. The limit rods 108 are fixedly connected to the rotating disk 3.

[0052] Preferably, in the initial state, the limiting rod 108 is at the inner upper end of the straight groove. When the transfer rod 103 needs to be driven to rotate, the rotating disk 3 drives a pair of limiting rods 108 to rotate. The limiting rods 108 are stuck in the straight groove, driving the transfer rod 103 to rotate, and the pair of tensioning rollers 2 can be driven to tension. 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 roller 2 to rotate slowly, and does not affect the tensioning work of the abrasive belt body 6.

[0053] Next, when the abrasive 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 separated from the straight groove. Then the rotating disk 3 rotates again, and the driving sleeve 107 can be driven to rotate alone, thereby driving the tensioning roller 2 to rotate, so that the abrasive belt body 6 moves, and the testing work can start;

[0054] When the inspection is completed and the abrasive belt body 6 needs to be removed, the rotating disk 3 is raised and reset, so that the limit rod 108 is re-engaged in the straight groove, and then the rotating disk 3 rotates in the opposite direction, thereby driving the transfer rod 103 to reverse, so that the pair of tensioning rollers 2 can be reset, and the staff can remove the abrasive belt body 6.

[0055] The upper end of the transfer rod 103 passes through the workbench 1 and is rotatably connected thereto. 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. A round chamfer is provided at the lower end of the clamping plates 111. A top cover 112 is fixedly connected to the upper end of the clamping plate 111. Guide telescopic columns are provided at both ends of the top cover 112, and the guide telescopic columns are connected to the workbench 1.

[0056] Preferably, when the limit rod 108 is separated from the straight groove and starts to drive the sand belt body 6 to move, the transfer rod 103 loses power restriction at this time, and the pair of tension rollers 2 cannot be kept in a tensioned state. Therefore, an annular groove 110 and a clamping plate 111 are provided. Specifically, before the limit rod 108 is separated from the straight groove, the top cover 112 is moved downward so that the pair of clamping plates 111 are clamped into the annular groove 110, thereby fixing the position of the transfer rod 103 to prevent it from deflecting. When the limit rod 108 is separated from the straight groove, the position of the tension roller 2 can be ensured to remain unchanged, the current tensioned state can be maintained, and the stability is improved.

[0057] Preferably, the lower end of the clamping plate 111 is provided with a round chamfer, so as to increase the error tolerance of clamping into the annular clamping groove 110 .

[0058] A center rod 109 passes through the inner side of the transfer rod 103 and is gap-fitted therewith. The lower end of the center rod 109 is fixedly connected to a pair of limit rods 108, and the upper end of the center rod 109 is rotatably connected to the top cover 112. After the clamping plate 111 and the annular clamping groove 110 are engaged with each other, the limit 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, when the rotating disk 3 drives a pair of tensioning rollers 2 to complete the tensioning of the abrasive belt body 6, the rotating disk 3 descends, driving the limit rod 108 to disengage from the straight groove. At this time, the limit rod 108 drives the center rod 109 to move downward, thereby driving the top cover 112 to move downward, so that the clamping plate 111 is first clamped into the annular clamping groove 110 for clamping, and then the limit rod 108 is completely disengaged from the straight groove, and the rotating disk 3 can drive the abrasive belt body 6 to move. In other words, only by moving the rotating disk 3 downward, the top cover 112 can be driven to move downward synchronously, and the clamping plate 111 will clamp the transfer rod 103 before it loses power restriction, with strong stability, and when the rotating disk 3 rises and resets, the top cover 112 also rises synchronously, releasing the jamming of the transfer rod 103, and the limit rod 108 can drive the transfer rod 103 to reverse, loosening the abrasive belt body 6, with good synchronization.

[0060] A pair of adapting grooves are provided at the lower end of the transfer rod 103 . The adapting grooves are adjacent to the straight grooves and are staggered. A spring telescopic rod is provided in the adapting groove. An arc-shaped inclined block 113 is provided at one end of the spring telescopic rod. The adapting groove is used to accommodate the arc-shaped inclined block 113 .

[0061] Preferably, when the detection work is completed and the abrasive belt body 6 needs to be relaxed, the rotating disk 3 needs to rise and reset. In order to accurately align the limit rod 108 and the straight groove to connect with each other, an arc-shaped inclined block 113 is provided. Specifically, when the abrasive belt body 6 is driven to move, the rotating disk 3 rotates to drive the limit rod 108 to rotate. At this time, the limit rod 108 moves along the inclined surface of the arc-shaped inclined block 113, thereby pressing it into the adaptation groove for avoidance without affecting the normal rotation of the rotating disk 3. When the rotating disk 3 needs to rise and reset, the rotating disk 3 is reversed, so that the limit rod 108 contacts the straight surface of the arc-shaped inclined block 113, and the adaptation groove is adjacent to the straight groove and is staggered, thereby automatically aligning the position of the limit rod 108 and the straight groove. At this time, the rotating disk 3 can rise, so that the limit rod 108 returns to the straight groove, which is highly practical.

[0062] The lower end of the fixed cavity 102 is rotatably connected with 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, the motor component 801 is used to drive the rotating cover 4, and the inner side of the rotating cover 4 is threadedly connected with 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 force between the two. That is to say, due to the existence of friction force, the rotating cover 4 will not easily drive the rotating disk 3 to rise and fall under normal conditions. When the rotating cover 4 is driven to rotate by the motor component 801, the rotating disk 3 is driven to rotate synchronously. At this time, the rotating disk 3 drives the transfer rod 103 to rotate, thereby driving a pair of tensioning rollers 2 to tension the sand belt body 6. After tensioning, the rotating cover 4 continues to rotate. Since the tensioning roller 2 cannot continue to move, that is, the transfer rod 103 and the rotating disk 3 cannot continue to rotate, they remain fixed. When the rotation driving force is greater than the above-mentioned friction force, the rotating cover 4 is relative to the rotating disk 3. Rotation, through threaded connection, and the limit rod 108 is guided along the straight groove displacement, driving the rotating disk 3 to descend, thereby driving the clamping plate 111 to clamp the transfer rod 103, and after the limit rod 108 is separated from the straight groove, the rotating disk 3 can continue to rotate, and the rotating cover 4 drives the rotating disk 3 to rotate again through friction, which can drive the driving sleeve 107 to rotate alone, and drive the sand belt body 6 to move. In other words, only through the drive of the rotating cover 4, the tensioning roller 2 can be driven to complete the tensioning, and then the tensioning roller 2 can be automatically adjusted to rotate, so that the sand belt body 6 moves. The degree of automation is high, and no additional drive components or control programs are required for control, which saves costs;

[0064] When resetting is required, the rotating disk 3 is reversed so that the limit rod 108 is aligned with the position of the straight groove. At this time, the limit rod 108 is restricted by the arc-shaped inclined block 113, so that the rotating disk 3 cannot continue to reverse. When the rotational driving force is greater than the friction force, the rotating cover 4 can drive the rotating disk 3 to rise, so that the limit rod 108 is reset to the straight groove, and the clamping plate 111 also disengages from the annular clamping groove 110, and the transfer rod 103 can be driven to reverse again, thereby loosening the sanding belt body 6.
