Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shoe product detection technology, in particular to a sole wear resistance testing device. Background Art
[0002] When wearing shoes, the average pressure generated by the soles contacting the human feet and the ground is 0.4-0.7MPa, and some parts can be as high as 1.5MPa or more, so the soles will be repeatedly subjected to considerable friction. Wear is a destructive phenomenon caused by friction. The wear resistance of the soles is directly related to the safety performance and service life of the product, so it is necessary to test the wear resistance of the soles.
[0003] The problem with the existing technology is that the traditional detection method obtains data by observing the wear degree of the sole through the rotation of the friction object and continuous contact with the sole. However, this type of detection method does not conform to the actual wearing and walking conditions of the shoe product. For example, when the shoe product is worn on the foot and walking, due to the characteristics of the force bending action of the foot, the main force points of the shoe product are concentrated on the sole and heel. The wear of these two places is significantly greater than that of other parts, and the traditional detection equipment does not have the function of local testing of the sole and heel.
[0004] Secondly, traditional friction materials are usually single settings such as sanding rollers, but the application environment of shoe products themselves is different. For example, running shoes, basketball shoes, etc. are concentrated on the bottom surfaces of different materials such as plastic tracks and board courts. A single sanding roller obviously cannot accurately detect such shoe products.
[0005] Therefore, it is necessary to improve the sole wear resistance testing device so that it can perform targeted local testing on the sole and heel of the shoe product and can simulate testing on ground surfaces of different materials. Utility Model Content
[0006] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a sole wear resistance testing device.
[0007] The utility model technical solution: a sole wear test device, including a fixing mechanism, a swing mechanism, and a friction mechanism, the fixing mechanism includes a bracket for fixing the sole, the bracket is provided with a flip shaft at the midpoint position corresponding to the length direction of the sole, the swing mechanism includes a stepping motor, a driving gear, a driven gear, a base, and a motor driver, the stepping motor output shaft is connected with the driving gear, the base is rotatably matched with the flip shaft, the driven gear is coaxially fixed with the flip shaft, and meshes with the driving gear;
[0008] The friction mechanism includes a friction piece arranged on one side of the bottom surface of the sole. The motor driver controls the stepper motor to rotate forward and reversely, driving the sole to flip back and forth around the flip axis. The sole and heel of the sole intermittently and reciprocally contact the friction piece as the sole flips.
[0009] By adopting the above technical solution, through the design of the swing mechanism, after the bracket fixes the sole, the sole is driven to flip back and forth around the flip axis, as shown in the attached manual. Figure 3 As shown, the sole and heel of the sole intermittently reciprocate in contact with the friction parts as the shoe is turned, simulating the state of the shoe when walking. The friction test is focused on the sole and heel to observe the wear.
[0010] The utility model is further configured as follows: the friction mechanism also includes a driving cylinder, a slide member, and a PLC controller. The slide member is arranged along the length direction of the sole. The friction member is arranged in the slide member for sliding cooperation and is detachably fixedly connected to the piston rod of the driving cylinder. The friction member is provided with an embedding groove, and friction plates of different materials can be detachably installed in the embedding groove. The PLC controller is linked to the motor driver signal to drive the friction member to slide back and forth with the forward and reverse rotation of the stepping motor.
[0011] With the above technical solution, only flipping the sole to contact the friction member is not enough to fully simulate the movement and force of the shoe. The PLC controller is linked with the motor driver signal. For example, when the sole of the shoe is flipped and pressed down to contact the friction member, the cylinder is driven to drive the friction member to slide relatively, causing scratches on the sole, further simulating the movement state of the sole and the state of friction with the ground.
[0012] At the same time, friction sheets that simulate the ground materials of different shoe sole usage environments, such as wooden sheets, cement casting sheets, friction sheets with asphalt attached, etc., are replaced and installed in the grooves to carry out wear resistance tests simulating different ground surfaces.
[0013] The utility model is further configured as follows: the fixing mechanism also includes a plurality of movable chucks and positioning screws; the bracket is provided with a sliding groove along the length of the sole; the side of the bracket is provided with an oblong groove penetrating into the sliding groove; the movable chuck includes a slider portion inserted in the sliding groove for sliding fit, and an extended arm portion extending toward the edge of the sole; the extended arm portion is provided with a clip for clamping the edge of the sole; the slider portion is provided with a threaded hole at a position corresponding to the oblong groove; the positioning screw passes through the oblong groove and is screwed into the threaded hole to fix the position of the slider portion.
[0014] By adopting the above technical solution, the position of the movable clamp is adjusted by moving it relative to the bracket sliding slot, and then the screw is tightened to fix it, and then the edge of the sole contour is fixed by the clamp, so as to form a fixed connection that can adapt to soles of different sizes.
[0015] A further configuration of the utility model is as follows: the fixing mechanism comprises a shoe last detachably connected to the bracket, and the shoe is put on the shoe last and flips back and forth with the shoe last.
[0016] By adopting the above technical solution, in addition to testing a single sole, by setting a shoe last, it is also possible to adapt shoes with uppers to perform fixed wear resistance tests.
[0017] The beneficial effects of the utility model are as follows: through the improved design of the fixing mechanism, the swinging mechanism, and the friction mechanism, the device can simulate the traveling state of the sole, perform wear resistance test, and perform local test on the sole and heel of the sole. At the same time, the friction plates of different materials can be replaced to simulate the wear resistance test on different ground surfaces. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1-3 As shown,
[0025] A wear-resistance testing device for a sole 1, comprising a fixing mechanism, a swinging mechanism, and a friction mechanism, wherein the fixing mechanism comprises a bracket 11 for fixing the sole 1, wherein the bracket 11 is provided with a turning shaft 12 at a midpoint position corresponding to the length direction of the sole 1, wherein the swinging mechanism comprises a stepping motor 21, a driving gear 22, a driven gear 23, a base 24, and a motor driver, wherein the output shaft of the stepping motor 21 is connected to the driving gear 22, wherein the base 24 is rotationally matched with the turning shaft 12, and the driven gear 23 is coaxially fixed with the turning shaft 12 and meshes with the driving gear 22;
[0026] The friction mechanism includes a friction member 31 arranged on one side of the bottom surface of the sole 1. The motor driver controls the stepper motor 21 to rotate forward and reverse, driving the sole 1 to flip back and forth around the flip axis 12. The sole and heel of the sole 1 intermittently and reciprocally contact the friction member 31 as it flips.
[0027] Through the design of the swing mechanism, after the support 11 fixes the sole 1, the sole 1 is driven to flip back and forth around the flip axis 12, as shown in the attached manual. Figure 3 As shown, the sole and heel of the sole 1 intermittently reciprocate in contact with the friction member 31 as the shoe turns, simulating the state of the shoe when walking, focusing on friction testing on the sole and heel to observe the wear condition.
[0028] The friction mechanism also includes a driving cylinder 32, a slide member 33, and a PLC controller. The slide member 33 is arranged along the length direction of the sole 1. The friction member 31 is arranged in the slide member 33 for sliding cooperation and is detachably fixedly connected to the piston rod of the driving cylinder 32. The friction member 31 is provided with an embedding groove, and a friction plate 34 of different materials can be detachably installed in the embedding groove. The PLC controller is linked with the motor driver signal to drive the friction member 31 to slide back and forth with the stepping motor 21 in forward and reverse rotation.
[0029] Simply flipping the sole 1 to contact the friction member 31 is not enough to fully simulate the movement and force of the shoe. The PLC controller is linked with the motor driver signal. For example, when the sole 1 is flipped and pressed down to contact the friction member 31, the cylinder 32 drives the friction member 31 to slide relatively, causing scratches with the sole 1, further simulating the movement state of the sole 1 and the state of friction with the ground.
[0030] At the same time, friction plates 34 simulating different ground materials for the sole 1, such as wooden plates, cement casting plates, friction plates 34 with asphalt attached, etc., are replaced and installed in the grooves to perform wear resistance tests simulating different ground surfaces.
[0031] The fixing mechanism also includes a plurality of movable chucks 4 and positioning screws. The bracket 11 is provided with a sliding groove 111 along the length of the sole 1. The side of the bracket 11 is provided with an oblong groove 112 that penetrates into the sliding groove 111. The movable chuck 4 includes a slider portion 41 inserted in the sliding groove 111 for sliding cooperation, and an extended arm portion 42 extending toward the edge of the sole 1. The extended arm portion is provided with a clip 43 for clamping the edge of the sole 1. The slider portion 41 is provided with a threaded hole corresponding to the position of the oblong groove 112. The positioning screw passes through the oblong groove 112 and is screwed into the threaded hole to fix the position of the slider portion 41.
[0032] By adopting the above technical solution, the position of the movable clamp 4 is adjusted relative to the sliding groove 111 of the bracket 11, and then the screws are tightened to fix it, and then the contour edge of the sole 1 is fixed by the clamp 43, so as to form a fixed connection that can adapt to soles 1 of different sizes.
[0033] The fixing mechanism comprises a shoe last detachably connected to the bracket 11 , and the shoe is put on the shoe last and flips back and forth with the shoe last.
[0034] In addition to testing a single sole 1, by setting a shoe last, shoes with uppers can also be adapted to perform fixed wear resistance tests.
[0035] Through the improved design of the fixing mechanism, the swinging mechanism, and the friction mechanism, the device can simulate the traveling state of the sole 1 to perform wear resistance test, and can perform local test on the sole and heel of the sole 1. At the same time, the friction plate 34 of different materials can be replaced to simulate the wear resistance test on different ground surfaces.
[0036] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the scope of protection of the present application.
