Detailed implementation manners

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, 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 used to limit the present invention.

[0019] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" mentioned in the present invention, unless otherwise specifically stated, both include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] In the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0021] Such as Figures 1 to 9As shown in the figure, a wear resistance detection device for a sole provided by an embodiment of the present invention includes a detection table 100. A turnover frame 200 is provided on the detection table 100. The turnover frame 200 can rotate around a horizontal axis. A clamping assembly 300 is slidably provided horizontally on the turnover frame 200. The clamping assembly 300 includes an installation cylinder 350. An installation groove 351 is coaxially provided inside the installation cylinder 350. A plurality of sole specimens 400 are slidably placed along the axial direction in the installation groove 351. At least two clamps 500 are provided inside the installation cylinder 350. The at least two clamps 500 are evenly distributed circumferentially around the installation groove 351, and the clamps 500 can slide radially along the installation cylinder 350. An articulated rod 630 is hinged to the outer periphery of the installation cylinder 350. A bearing plate 640 is rotatably provided at the end of the articulated rod 630. The bearing plate 640 is always perpendicular to the articulated rod 630. The articulated rod 630 corresponds to the clamp 500 one by one, and a transmission mechanism 600 is provided between the articulated rod 630 and the clamp 500. The articulated rod 630 has a first state and a second state. When the articulated rod 630 is in the first state, the articulated rod 630 is parallel to the axis of the installation cylinder 350. At this time, the bearing plate 640 can limit the protruding length of the sole specimen 400 from the installation groove 351. When the articulated rod 630 is in the second state, the articulated rod 630 is perpendicular to the axis of the installation cylinder 350. The articulated rod 630 drives the clamp 500 to slide radially along the installation cylinder 350 through the transmission mechanism 600, so that the sole specimen 400 is clamped in the installation groove 351.

[0022] Among them, each sole specimen 400 is cylindrical, and the number of articulated rods 630 is two. In other embodiments, the number of articulated rods 630 can be three or four. A grinding wheel is provided below the turnover frame 200. The axis of the grinding wheel is horizontally arranged. The grinding wheel is used to grind the sole specimen 400.

[0023] In this way, before detection, a plurality of sole specimens 400 are pre-placed in the installation cylinder 350 at one time. After one sole specimen 400 is detected, it is removed from the installation cylinder 350, and then the undetected sole specimens 400 are continuously detected. Thus, it is not necessary to separately install and clamp each sole specimen 400, improving the wear resistance detection efficiency. At the same time, the bearing plate 640 can ensure that the protruding length of each sole specimen 400 from the installation groove 351 is consistent, reducing the error caused by sole specimens 400 of different sizes and improving the wear resistance detection accuracy.

[0024] Further, a hinge shaft 620 is fixedly provided on the outer peripheral surface of the mounting cylinder 350. The hinge shaft 620 extends along the radial direction of the mounting cylinder 350. One end of the hinge rod 630 is hinged to the hinge shaft 620, and a fixed cylinder is provided at the other end of the hinge rod 630. The axis of the fixed cylinder extends along the length direction of the hinge rod 630. A fixed shaft is provided on the bearing plate 640. The fixed shaft is rotationally and slidably matched with the fixed cylinder coaxially, and the fixed shaft and the fixed cylinder can slide relative to each other in the length direction of the hinge rod 630.

[0025] 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, and further the protruding length of the sole specimen 400 from the mounting groove 351 can be changed.

[0026] By rotating the fixed shaft relative to the fixed cylinder, the bearing plate 640 can be rotated relative to the hinge rod 630. When the hinge rod 630 is in the first state, the bearing plate 640 has a bearing position directly below the mounting cylinder 350. At this time, the bearing plate 640 can support the sole specimen 400 in the mounting cylinder 350; when the bearing plate 640 rotates relative to the hinge rod 630 to a position away from directly below the mounting cylinder 350, the bearing plate 640 no longer supports the sole specimen 400 in the mounting cylinder 350 and no longer blocks the mounting groove 351. At this time, it is convenient to install the sole specimen 400 into the mounting groove 351 or take out the sole specimen 400 from the mounting groove 351.

[0027] Further, a plurality of clamping grooves 632 extending along the axial direction of the fixed cylinder are provided on the inner wall of the fixed cylinder. The clamping grooves 632 are evenly distributed circumferentially around the inner wall of the fixed cylinder. A plurality of clamping blocks 642 are elastically connected circumferentially to the fixed shaft. The clamping blocks 642 can expand and contract along the radial direction of the fixed shaft and enter the clamping grooves 632, and the clamping blocks 642 can slide along the extending direction of the clamping grooves 632. By providing the clamping grooves 632 and the clamping blocks 642, the rotation angle of the bearing plate 640 relative to the hinge rod 630 can be limited. As Figure 7 shown, in this embodiment, four clamping grooves 632 are provided and two clamping blocks 642 are provided. The rotation angle of the fixed shaft relative to the fixed cylinder can be 90°, 180° and 270°. In this way, it can be ensured that the bearing plate 640 will not block the mounting groove 351 after rotation. In other embodiments, six or eight clamping grooves 632 can be provided, etc.

[0028] Furthermore, the fixed shaft is provided with a receiving groove 641 corresponding to the clamping block 642, and a first spring 643 is provided between the clamping block 642 and the groove wall of the receiving groove 641. The first spring 643 has a tendency to make the clamping block 642 enter the clamping groove 632. The cross section of the clamping block 642 perpendicular to the axis of the fixed cylinder is a triangle. When the bearing plate 640 rotates around the hinge rod 630, the clamping block 642 can be separated from the clamping groove 632. The first spring 643 is provided to ensure that when there is no external force to rotate the bearing plate 640 relative to the hinge rod 630, the clamping block 642 and the clamping groove 632 are locked and the bearing plate 640 will not rotate at will; when there is an external force to rotate the bearing plate 640 relative to the hinge rod 630, the clamping block 642 can be separated from the clamping groove 632 to make the bearing plate 640 rotate.

[0029] Further, the transmission mechanism 600 includes a telescopic rod 610, which is a hydraulic telescopic rod. A first fixed shaft 621 is provided in the middle of the hinge shaft 620, and a second fixed shaft 631 is provided in the middle of the hinge shaft 630. The two ends of the telescopic rod 610 are respectively hinged on the first fixed shaft 621 and the second fixed shaft 631, and a transmission ring 611 is fixedly provided at one end of the telescopic rod 610 hinged to the first fixed shaft 621; a fixed seat 352 is fixedly provided on the outer periphery of the mounting tube 350, and the clamp 500 has a clamping portion 501 located in the mounting tube 350 and a sliding portion 502 located in the fixed seat 352. Specifically, a limiting groove 354 is provided on the mounting tube 350, and the sliding portion 502 of the clamp 500 passes through the limiting groove 354 and enters the fixed seat 352, and the limiting groove 354 can limit the movement of the clamp 500 in the axial direction of the mounting tube 350. The clamping portion 501 has an arc-shaped clamping surface, which is convenient for contacting the cylindrical sole sample 400. The sliding portion 502 is provided with a slide groove 503, which extends along the radial direction of the mounting tube 350. A slider 680 is slidably provided in the slide groove 503. The rotation of the transmission ring 611 can make the slider 680 slide along the slide groove 503 to push the clamping portion 501, so that the clamping portion 501 clamps the sole sample 400.

[0030] Furthermore, the fixing seat 352 is also provided with a first transmission shaft and a second transmission shaft, the transmission ring 611 is connected to the first transmission shaft through a belt 650, a first gear 660 is provided in the middle of the first transmission shaft, a second gear 670 is provided in the middle of the second transmission shaft, the first gear 660 meshes with the second gear 670, and a first rack is provided on the slider 680, the first rack meshes with the second gear 670. In this way, when the hinge rod 630 moves from the second state to the first state, the slider 680 moves toward the direction close to the mounting tube 350.

[0031] Further, 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 reset of the slider 680 when the articulated rod 630 returns from the second state (clamping state) to the first state (relaxed state).

[0032] Further, a horizontally arranged guiding plate 110 is provided on the flipping frame 200. The clamping assembly 300 further includes a sliding plate 330 which can slide along the guiding plate 110. Such a setting facilitates the horizontal sliding of the clamping assembly 300 along the flipping frame 200.

[0033] Further, the clamping assembly 300 further includes a driving motor 320 which is supported on the sliding plate 330. An output end of the driving motor 320 is provided with a driving gear 340 which is fixedly arranged above the mounting cylinder 350. A second rack 120 extending in the horizontal direction is further provided on the test bench 100. The driving gear 340 meshes with the second rack 120, so that the mounting cylinder 350 rotates while horizontally moving along the test bench 100.

[0034] Further, a counterweight 310 is provided above the driving motor 320. The counterweight 310 is used to apply a load to the sole specimen 400. The counterweight 310 can keep the sole specimen 400 in contact with the grinding wheel. By installing counterweights 310 of different weights, the pressure between the sole specimen 400 and the grinding wheel is adjusted, so as to apply different loads to the sole specimen 400.

[0035] Combined with the above embodiments, the working principle and process of the embodiments of the present invention are as follows: In the initial state, the articulated rod 630 is in the first state, and the bearing plate 640 rotates to a position where it does not block the mounting groove 351. By rotating the flipping 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 the horizontal state. Then, a plurality of sole specimens 400 are placed in the mounting groove 351 along the axial direction of the mounting cylinder 350 at one time, and then the bearing plate 640 is rotated to the position corresponding to the mounting groove 351. As Figure 9 shown, the bearing plate 640 corresponds to the sole specimen 400.

[0036] Then, the flipping frame 200 is flipped so that the mounting cylinder 350 approaches the grinding wheel. At this time, the axis of the mounting cylinder 350 is in the vertical state. Under the action of gravity, the sole specimen 400 slides in the mounting groove 351, so that the lower part of the sole specimen 400 contacts the bearing plate 640, and the bearing plate 640 can limit the length of the sole specimen 400 extending out of the mounting groove 351.

[0037] Then, rotate the two hinge rods 630 in sequence so that the hinge rods 630 are all in the second state. The rotation of the hinge rods 630 drives the telescopic rod 610 to contract. At the same time, the telescopic rod 610 drives the transmission ring 611 to rotate. The transmission ring 611 synchronously drives the first gear 660 to rotate through the belt 650. The first gear 660 drives the second gear 670 to rotate. The second gear 670 drives the slider 680 to slide along the chute 503 in the direction close to the mounting cylinder 350. The slider 680 compresses the second spring 690 and pushes the clamping part 501 of the fixture 500 to push against the outer peripheral surface of the sole specimen 400. Since the two hinge rods 630 rotate in sequence, the two bearing plates 640 will not be separated from the sole specimen 400 at the same time, preventing the sole specimen 400 from continuing to slide down along the mounting groove 351. When the two hinge rods 630 are both rotated to the second state, the sole specimen 400 is pushed by the two fixtures 500 to the central position of the mounting groove 351 and clamped. At this time, control the grinding sand belt to rotate through the operation panel provided on the test bench 100, and start the driving motor 320. The driving motor 320 drives the driving gear 340 to rotate. The meshing of the driving gear 340 and the second rack 120 causes the entire clamping assembly 300 to slide horizontally along the guide plate 110 on the flipping frame 200. At the same time, the mounting cylinder 350 rotates self, realizing the wear resistance detection of the first sole specimen 400 below.

[0038] After the detection of the first sole specimen 400 is completed, rotate one of the hinge rods 630 from the second state to the first state. As a result, the fixture 500 corresponding to this hinge rod 630 no longer clamps the sole specimen 400, and only the fixture 500 corresponding to the other hinge rod 630 can push the sole specimen 400. At this time, the sole specimen 400 is in an eccentric position in the mounting groove 351 and will not slide. Then rotate the bearing plate 640 on the hinge rod 630 in the first state to a position that does not block the mounting groove 351, remove the first sole specimen 400 below, and then rotate the bearing plate 640 back to a position that blocks the mounting groove 351. Then rotate the other hinge rod 630 to the first state so that the bearing plates 640 of the two hinge rods 630 both correspond to the position of the mounting groove 351. Under the action of gravity, the remaining sole specimens 400 slide down along the mounting groove 351, and the two bearing plates 640 limit the protruding length of the second sole specimen 400 below from the mounting groove 351. Then rotate the two hinge rods 630 from the first state to the second state, and the clamping of the second sole specimen 400 below can be realized. At this time, control the grinding sand belt to rotate through the operation panel provided on the test bench 100 and start the driving motor 320 to realize the wear resistance detection of the second sole specimen 400 below.

[0039] Repeat this process to finish the grinding of all sole specimens 400. Finally, measure the wear volume or wear mass of all sole specimens 400 to complete the detection.

[0040] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, 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, it should be considered as the scope described in this specification.

[0041] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
