Description

Technical Field

[0001] The invention relates to the technical field of wear-resistant detection equipment, in particular to a wear-resistant performance detection device for a shoe sole. Background Art

[0002] Rubber is a common material for shoe soles due to its elasticity, wear resistance, and anti-slip properties. When testing the wear resistance of rubber soles, the sole specimen is typically cut into a cylindrical shape. The specimen is then mounted on a testing machine, a specified load is applied, and the machine is activated to rub the specimen against a grinding wheel. Finally, the weight or volume loss of the specimen is measured to calculate the wear.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings). In the description of the present invention, it should be understood that terms such as "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate positions or relationships based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the device or component being referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0031] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0032] like Figures 1 to 9 As shown, an embodiment of the present invention provides a wear resistance testing device for a sole, comprising a testing platform 100, wherein the testing platform 100 is provided with a flip frame 200, the flip frame 200 being capable of rotating around a horizontal axis, the flip frame 200 being provided with a clamping assembly 300 for horizontal sliding, the clamping assembly 300 comprising a mounting cylinder 350, the interior of the mounting cylinder 350 being coaxially provided with a mounting groove 351, a plurality of sole specimens 400 being placed in the mounting groove 351 for sliding along its axial direction, the interior of the mounting cylinder 350 being provided with at least two clamps 500, the at least two clamps 500 being evenly distributed around the circumference of the mounting groove 351, and the clamps 500 being capable of sliding radially along the mounting cylinder 350; a hinged rod 630 is hingedly connected to the periphery of the mounting cylinder 350, the end of the hinged rod 630 A supporting plate 640 is provided for rotation, and the supporting plate 640 and the hinge rod 630 are always arranged perpendicularly; the hinge rod 630 corresponds to the clamp 500 one by one, and a transmission mechanism 600 is provided between the hinge rod 630 and the clamp 500; the hinge rod 630 has a first state and a second state. When the hinge rod 630 is in the first state, the hinge rod 630 is parallel to the axis of the mounting tube 350. At this time, the supporting plate 640 can limit the extension length of the sole sample 400 from the mounting groove 351; when the hinge rod 630 is in the second state, the hinge rod 630 is perpendicular to the axis of the mounting tube 350. The hinge rod 630 drives the clamp 500 to slide radially along the mounting tube 350 through the transmission mechanism 600, so that the sole sample 400 is clamped in the mounting groove 351.

[0033] Each sole specimen 400 is cylindrical and has two hinged rods 630. In other embodiments, three or four hinged rods 630 may be provided. A grinding wheel is provided below the turning frame 200, with its axis arranged horizontally. The grinding wheel is used to grind the sole specimen 400.

[0034] In this way, before testing, multiple sole samples 400 are pre-placed in the mounting tube 350 at once. After testing a sole sample 400, it is removed from the mounting tube 350, and testing of the untested sole sample 400 is continued. This eliminates the need to separately install and clamp each sole sample 400, thereby improving the efficiency of wear resistance testing. Furthermore, the supporting plate 640 ensures that each sole sample 400 extends to a consistent length from the mounting slot 351, reducing errors caused by sole samples 400 of different sizes and improving the accuracy of wear resistance testing.

[0035] Furthermore, a hinge shaft 620 is fixedly provided on the outer peripheral surface of the mounting cylinder 350, and the hinge shaft 620 extends radially along the mounting cylinder 350. One end of the hinge rod 630 is hinged to the hinge shaft 620, and the other end of the hinge rod 630 is provided with a fixed cylinder, and the axis of the fixed cylinder extends along the length direction of the hinge rod 630. A fixed shaft is provided on the supporting plate 640, and the fixed shaft and the fixed cylinder are coaxially rotated, and the fixed shaft and the fixed cylinder can slide relative to each other in the length direction of the hinge rod 630.

[0036] In this way, by adjusting the sliding distance between the fixed shaft and the fixed cylinder, the distance between the bearing plate 640 and the mounting cylinder 350 can be changed, thereby changing the extension length of the sole sample 400 from the mounting groove 351 .

[0037] The fixed shaft rotates relative to the fixed cylinder, allowing the supporting plate 640 to rotate relative to the hinge rod 630. When the hinge rod 630 is in the first state, the supporting plate 640 has a supporting position directly below the mounting cylinder 350. At this time, the supporting plate 640 can support the sole sample 400 in the mounting cylinder 350. When the supporting plate 640 rotates relative to the hinge rod 630 to a position away from directly below the mounting cylinder 350, the supporting plate 640 no longer supports the sole sample 400 in the mounting cylinder 350 and no longer blocks the mounting groove 351. This facilitates installation of the sole sample 400 into or removal of the sole sample 400 from the mounting groove 351.

[0038] Furthermore, the inner wall of the fixed cylinder is provided with a plurality of slots 632 extending along the axial direction of the fixed cylinder. The slots 632 are evenly distributed around the inner wall of the fixed cylinder. The fixed shaft is elastically connected to a plurality of blocks 642 in the circumferential direction. The blocks 642 can be extended and retracted along the radial direction of the fixed shaft and enter the slots 632. The blocks 642 can also slide along the extension direction of the slots 632. By providing the slots 632 and the blocks 642, the rotation angle of the support plate 640 relative to the hinge rod 630 can be limited. Figure 7As shown, in this embodiment, there are four locking slots 632 and two locking blocks 642. The rotation angles of the fixed shaft relative to the fixed cylinder can be 90°, 180°, and 270°, which can ensure that the supporting plate 640 does not block the mounting slot 351 after rotation. In other embodiments, there can be six or eight locking slots 632, etc.

[0039] Furthermore, the fixed shaft is provided with a receiving groove 641 corresponding to the clamping block 642. A first spring 643 is provided between the clamping block 642 and the wall of the receiving groove 641. The first spring 643 tends to force the clamping block 642 into the clamping groove 632. The clamping block 642 has a triangular cross-section perpendicular to the axis of the fixed cylinder. When the supporting plate 640 rotates about the hinge rod 630, the clamping block 642 can disengage from the clamping groove 632. The first spring 643 ensures that when there is no external force causing the supporting plate 640 to rotate relative to the hinge rod 630, the clamping block 642 and the clamping groove 632 are locked in place, preventing the supporting plate 640 from rotating freely. When an external force causes the supporting plate 640 to rotate relative to the hinge rod 630, the clamping block 642 can disengage from the clamping groove 632, allowing the supporting plate 640 to rotate.

[0040] Furthermore, the transmission mechanism 600 includes a telescopic rod 610, which is a hydraulic telescopic rod. A first fixed axis 621 is provided in the middle of the hinge shaft 620, and a second fixed axis 631 is provided in the middle of the hinge shaft 630. The two ends of the telescopic rod 610 are respectively hinged to the first fixed axis 621 and the second fixed axis 631. A transmission ring 611 is fixed to the end of the telescopic rod 610 hinged to the first fixed axis 621. A fixed seat 352 is fixed to the outer periphery of the mounting tube 350. The clamp 500 includes a clamping portion 501 located within the mounting tube 350 and a sliding portion 502 located within the fixed seat 352. Specifically, a limiting groove 354 is provided on the mounting tube 350. The sliding portion 502 of the clamp 500 passes through the limiting groove 354 and enters the fixed seat 352. The limiting groove 354 can limit the axial movement of the clamp 500 within the mounting tube 350. The clamping portion 501 has an arcuate clamping surface, which facilitates contact with the cylindrical sole specimen 400. The sliding portion 502 is provided with a slide groove 503, which extends radially along the mounting cylinder 350. A slider 680 is slidably disposed within the slide groove 503. Rotation of the transmission ring 611 causes the slider 680 to slide along the slide groove 503, thereby pushing the clamping portion 501 and clamping the sole specimen 400.

[0041] Furthermore, the fixing base 352 is provided with a first transmission shaft and a second transmission shaft. The transmission ring 611 is connected to the first transmission shaft via a belt 650. A first gear 660 is provided in the middle of the first transmission shaft, and a second gear 670 is provided in the middle of the second transmission shaft. The first gear 660 meshes with the second gear 670. The slider 680 is provided with a first rack, which meshes with the second gear 670. This ensures that when the hinged rod 630 moves from the second state to the first state, the slider 680 moves toward the mounting cylinder 350.

[0042] Furthermore, a second spring 690 is connected between the slider 680 and the clamping portion 501. The second spring 690 has a tendency to move the slider 680 away from the clamping portion 501. The second spring 690 can promote the return of the slider 680 when the hinged rod 630 returns from the second state (clamped state) to the first state (relaxed state).

[0043] Furthermore, the flip frame 200 is provided with a horizontally arranged guide plate 110, and the clamping assembly 300 further includes a sliding plate 330, which can slide along the guide plate 110. This arrangement facilitates the clamping assembly 300 to slide horizontally along the flip frame 200.

[0044] Furthermore, the clamping assembly 300 also includes a drive motor 320, which is supported on the sliding plate 330, and a drive gear 340 is provided at the output end of the drive motor 320. The drive gear 340 is fixedly provided above the mounting tube 350. The detection platform 100 is also provided with a second rack 120 extending in the horizontal direction. The drive gear 340 is engaged with the second rack 120, so that the mounting tube 350 moves horizontally along the detection platform 100 while rotating.

[0045] Furthermore, a counterweight 310 is provided above the drive motor 320 to apply a load to the sole sample 400. The counterweight 310 maintains contact between the sole sample 400 and the grinding wheel. By installing counterweights 310 of varying weights, the pressure between the sole sample 400 and the grinding wheel can be adjusted, thereby applying different loads to the sole sample 400.

[0046] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0047] In the initial state, the hinge rod 630 is in the first state, and the supporting plate 640 is rotated to a position that does not block the mounting groove 351. By rotating the flip frame 200, the mounting cylinder 350 is moved away from the grinding wheel. At this time, the axis of the mounting cylinder 350 is in a horizontal state. Then, multiple sole samples 400 are placed in the mounting groove 351 along the axial direction of the mounting cylinder 350 at one time, and then the supporting plate 640 is rotated to the position corresponding to the mounting groove 351. Figure 9 As shown, the bearing plate 640 corresponds to the sole sample 400 .

[0048] The flip frame 200 is then flipped over, positioning the mounting cylinder 350 close to the grinding wheel. The axis of the mounting cylinder 350 is now vertical. Under the force of gravity, the sole sample 400 slides within the mounting groove 351, causing the bottom of the sole sample 400 to contact the supporting plate 640. The supporting plate 640 limits the length of the sole sample 400 extending from the mounting groove 351.

[0049] Then, the two hinged rods 630 are rotated sequentially, placing both hinged rods 630 in the second state. The rotation of the hinged rods 630 causes the telescopic rod 610 to retract, while the telescopic rod 610 simultaneously causes the transmission ring 611 to rotate. The transmission ring 611, via the belt 650, synchronously causes the first gear 660 to rotate. The first gear 660 then causes the second gear 670 to rotate. The second gear 670 then causes the slider 680 to slide along the slide groove 503 toward the mounting tube 350. The slider 680 compresses the second spring 690 and pushes the clamping portion 501 of the fixture 500 against the outer surface of the sole sample 400. The sequential rotation of the two hinged rods 630 prevents the two supporting plates 640 from simultaneously separating from the sole sample 400, preventing the sole sample 400 from sliding further down the mounting groove 351. When both hinged rods 630 are rotated to the second state, the sole sample 400 is pushed to the center of the mounting groove 351 by the two fixtures 500 and clamped. At this time, the rotation of the grinding belt is controlled by the operation panel provided on the testing platform 100, and the driving motor 320 is started. The driving motor 320 drives the driving gear 340 to rotate. The engagement of the driving gear 340 with the second rack 120 causes the clamping assembly 300 to slide horizontally along the guide plate 110 on the flip frame 200 as a whole. At the same time, the mounting cylinder 350 rotates, thereby realizing the wear resistance test of the first sole sample 400 below.

[0050] After testing the first sole sample 400, one of the hinged rods 630 is rotated from the second position to the first position. This allows the clamp 500 corresponding to that hinged rod 630 to no longer grip the sole sample 400, leaving only the clamp 500 corresponding to the other hinged rod 630 able to push against the sole sample 400. At this point, the sole sample 400 is eccentrically positioned within the mounting slot 351 and prevents it from sliding. The supporting plate 640 on the hinged rod 630 in the first position is then rotated to a position that does not obstruct the mounting slot 351. The first sole sample 400 below is removed, and the supporting plate 640 is rotated back to a position that obstructs the mounting slot 351. The other hinged rod 630 is then rotated to the first position, aligning the supporting plates 640 of both hinged rods 630 with the mounting slot 351. Under the action of gravity, the remaining sole sample 400 slides downward along the mounting slot 351, with the two supporting plates 640 limiting the extension of the second sole sample 400 from the mounting slot 351. Then, the two hinged rods 630 are rotated from the first state to the second state to clamp the second sole sample 400. At this time, the operation panel provided on the testing platform 100 controls the rotation of the abrasive belt and starts the drive motor 320 to perform the wear resistance test on the second sole sample 400.

[0051] This process is repeated to achieve grinding of all the sole samples 400 , and finally the wear volume or wear mass of all the sole samples 400 is measured to complete the test.

[0052] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
