Description

Technical Field

[0001] This utility model relates to the field of shoe sole abrasion resistance testing technology, and more specifically, to a clamping anti-damage structure for a shoe sole abrasion resistance tester. Background Technology

[0002] In the field of shoe sole abrasion testing technology, the shoe sole abrasion tester is a core device for evaluating the abrasion resistance of shoe sole materials, and its testing accuracy is closely related to the performance of the fixture. For example, Chinese invention patent application number 202311309661.8 discloses a shoe sole abrasion testing device and method. This device, by setting up a support mechanism, uses a spring to provide elasticity so that the shoe sole is in close contact with the abrasion wheel during the test, which to a certain extent ensures the normal conduct of the test.

[0003] However, existing technologies still have many shortcomings. The fixing components in the aforementioned comparative documents rely on a relatively simple clamping method for the sole, primarily using the elasticity of the support mechanism to achieve contact between the sole and the grinding wheel. This makes it difficult to accurately and stably fix soles of different shapes and sizes. During testing, if the sole shape is irregular or the size varies significantly, it is prone to wobbling or uneven stress, which not only affects the accuracy of the test results but may also lead to abnormal sole wear, failing to accurately reflect the abrasion resistance of the sole material. Furthermore, the contact area between the clamp and the sole lacks effective damage prevention design. Under high-frequency friction testing, the rigid contact between the clamp and the sole easily leads to rapid wear of the clamp surface, shortening the clamp's lifespan and increasing equipment maintenance costs. At the same time, excessive pressure from the clamp on the sole may also damage the sole surface, interfering with the reliability of the test data. Therefore, there is an urgent need to design a damage prevention structure for the sole abrasion machine clamp that can adapt to various soles, effectively reduce clamp wear, and improve testing accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping anti-damage structure for a shoe sole abrasion machine, so as to solve the problem that the positioning mechanism mentioned in the background art has a relatively simple clamping method for the shoe sole, mainly relying on the elasticity of the support mechanism to achieve the fit between the shoe sole and the grinding wheel, which makes it difficult to accurately and stably fix shoe soles of different shapes and sizes.

[0005] To achieve the above objectives, this utility model provides a clamping anti-damage structure for a shoe sole abrasion machine, including a base. Clamping components for clamping the shoe sole from both sides are installed on the top two sides of the base. A support component for supporting the shoe sole is installed in the middle of the top of the base. A clamping head is installed at the upper end of each clamping component. A driving component is installed inside the base near the lower end of the clamping component. The middle part of the clamping component is rotatably connected to the base via a pin. The driving component drives the lower end of the clamping component to move, and through leverage, drives the upper clamping head to press and fix the side of the shoe sole.

[0006] This base serves as the fundamental support for the entire clamping and damage prevention structure. Clamping components are installed on both sides of its top, and a support component is installed in the middle. The middle of the clamping component is rotatably connected to the base via a pin, forming a lever structure. The drive component is installed inside the base near the lower end of the clamping component. When the drive component moves the lower end of the clamping component, according to the lever principle, the clamping head at the upper end of the clamping component will move in the opposite direction, thereby pressing and fixing the side of the shoe sole.

[0007] Preferably, the clamping component includes a clamping rod, and the clamping head is fixed to the top of the clamping rod.

[0008] This setting clarifies that the clamping component consists of a clamping rod and a clamping head. The clamping head is fixed to the top of the clamping rod. The clamping rod, as a force transmission component, transmits the force generated by the driving component to the clamping head, enabling the clamping head to perform clamping operations on the shoe sole.

[0009] Preferably, the clamping head includes a bottom shell, a soft pad is installed on the front of the bottom shell, and a plurality of springs are installed inside the bottom shell, with one end of each spring abutting against the back of the soft pad.

[0010] The bottom shell of this clamping head is used to install and secure other components. A soft pad is installed on the front of the bottom shell, and several springs are installed inside the bottom shell, with one end of the springs abutting against the back of the soft pad. When the clamping head clamps the sole of the shoe, the sole exerts pressure on the soft pad. The soft pad compresses the springs under pressure, causing the springs to undergo elastic deformation, thereby buffering the force between the sole and the clamping head.

[0011] Preferably, the soft pad is covered with an abrasion-resistant sleeve, the outer surface of which is in contact with the side of the shoe sole.

[0012] This feature includes an abrasion-resistant sleeve covering the outer surface of the insole, with the outer surface of the sleeve conforming to the side of the sole. During sole abrasion resistance testing, the abrasion-resistant sleeve directly contacts the sole, bearing the friction between the sole and the clamping head.

[0013] Preferably, the padding has an inwardly concave arc-shaped structure that fits against the side protrusion of the sole.

[0014] This design incorporates an inwardly concave, curved padding structure that conforms to the raised side of the sole. When gripping the sole, this conformation increases the contact area between the gripper head and the sole, resulting in a more even gripping force in all directions.

[0015] Preferably, the bottom of the support component is driven to move up and down by a lifting component, which is a lifting cylinder. The bottom end of the lifting cylinder is fixed to the bottom inner wall of the base, and the top output shaft of the lifting cylinder is connected and fixed to the bottom of the support component.

[0016] This setup features a support component whose bottom is driven to rise and fall by a lifting mechanism, specifically a lifting cylinder. The bottom end of the cylinder is fixed to the inner wall of the base, and the top output shaft is connected and fixed to the bottom of the support component. When the lifting cylinder operates, its output shaft extends or retracts, thereby causing the support component to rise or fall.

[0017] Preferably, the top center of the support component has a flat structure to horizontally support the bottom of the shoe sole.

[0018] This feature includes a flat structure at the top center of the support component, which contacts the bottom of the sole to provide horizontal support.

[0019] Preferably, the driving component is a driving cylinder, which is horizontally fixed inside the base by a bracket, and the end of the driving cylinder abuts against the bottom end of the clamping component.

[0020] The driving component in this configuration is a drive cylinder, which is horizontally fixed inside the base by a bracket, with the cylinder end abutting the bottom end of the clamping component. When the drive cylinder operates, its end extends or retracts, thereby pushing or pulling the lower end of the clamping component, causing it to rotate around the pivot pin.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] The anti-damage clamping structure of this shoe sole abrasion tester utilizes clamping components on both sides of the top of the base and a supporting component in the middle to secure the shoe sole in multiple directions. The drive component moves the lower end of the clamping component, using leverage to press the clamping head firmly against the side of the shoe sole. Combined with the lifting component at the bottom of the supporting component, the support height can be flexibly adjusted. Whether it's a regular shoe sole or an irregularly shaped or different-sized sole, precise and stable fixation can be achieved, effectively avoiding problems such as sole wobbling or uneven stress during testing, significantly improving the accuracy and reliability of test results.

[0023] The clamping head adopts a combination design of bottom shell, soft pad, spring and wear-resistant sleeve. The elastic deformation of the spring can buffer the force between the clamp and the shoe sole and reduce rigid contact. The wear-resistant sleeve outside the soft pad is made of wear-resistant material, which can significantly reduce the degree of wear when rubbing against the shoe sole. Moreover, the wear-resistant sleeve is detachable and replaceable. When wear occurs, it can be replaced in time, thereby effectively extending the overall service life of the clamp and reducing equipment maintenance costs.

[0024] The inwardly concave curved pad fits snugly against the raised side of the sole, ensuring a firm grip while avoiding excessive compression damage to the sole surface, thus ensuring that the test data accurately reflects the abrasion resistance of the sole material. The flat structure at the top of the support component can horizontally support the bottom of the sole, and together with the clamping components on both sides, it ensures that the sole is subjected to uniform force during the test, further improving the test accuracy.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides a clamping anti-damage structure for a shoe sole abrasion-resistant machine, such as... Figure 1 , Figure 2 As shown, the device includes a base 1, clamping components 2 for clamping the sole 6 on both sides of the top of the base 1, and a support component 3 for supporting the sole 6 in the middle of the top of the base 1. A clamping head 22 is installed at the upper end of the clamping component 2. A driving component 4 is installed inside the base 1 near the lower end of the clamping component 2. The middle part of the clamping component 2 is rotatably connected to the base 1 through a pin 23. The driving component 4 drives the lower end of the clamping component 2 to move, and through the lever action, drives the upper clamping head 22 to press and fix the side of the sole 6.

[0032] The base 1 serves as the fundamental support for the entire anti-damage clamping structure. Clamping components 2 for gripping the sole 6 from both sides are installed on its top two sides, and a support component 3 for supporting the sole 6 is installed in the middle of the top. The clamping components 2 are rotatably connected to the base 1 via a pin 23, forming a lever structure. A drive component 4 is installed inside the base 1 near the lower end of the clamping components 2. When the drive component 4 moves the lower end of the clamping components 2, according to the lever principle, the clamping head 22 at the upper end of the clamping components 2 will move in the opposite direction, thereby pressing and fixing the sides of the sole 6. This design achieves effective clamping of both sides of the sole 6, and the lever action allows for easy control of the clamping force, improving the stability and reliability of the clamp's fixation of the sole 6, while also making the entire structure more compact and space-saving.

[0033] In this embodiment, as Figure 2 As shown, the clamping component 2 includes a clamping rod 21, and a clamping head 22 is fixed to the top of the clamping rod 21.

[0034] The clamping component 2 includes a clamping rod 21, with a clamping head 22 fixed to the top of the clamping rod 21. The clamping rod 21 acts as a force transmission component, transmitting the force generated by the driving component 4 to the clamping head 22, enabling the clamping head 22 to perform a clamping operation on the shoe sole 6. This structural design is simple and clear, easy to manufacture and install, ensures effective force transmission, and ensures that the clamping head 22 can accurately apply clamping force to the shoe sole 6.

[0035] Specifically, such as Figure 3 As shown, the clamping head 22 includes a bottom shell 221, a soft pad 222 is installed on the front of the bottom shell 221, and a number of springs 223 are installed inside the bottom shell 221, with one end of the spring 223 abutting against the back of the soft pad 222.

[0036] The bottom shell 221 of the clamping head 22 is used to install and fix other components. A soft pad 222 is installed on the front of the bottom shell 221, and several springs 223 are installed inside. One end of the springs 223 abuts against the back of the soft pad 222. When the clamping head 22 clamps the sole 6, the sole 6 exerts pressure on the soft pad 222. The soft pad 222 compresses the springs 223, causing the springs 223 to undergo elastic deformation, thus buffering the force between the sole 6 and the clamping head 22. The buffering effect of the springs 223 reduces the rigid contact between the sole 6 and the clamping head 22, avoiding damage to the sole 6 due to excessive clamping force, while also reducing the wear of the clamping head 22 itself and extending its service life.

[0037] Furthermore, such as Figure 3 As shown, the soft pad 222 is covered with a wear-resistant sleeve 224, and the outer surface of the wear-resistant sleeve 224 is in contact with the side of the sole 6.

[0038] An abrasion-resistant sleeve 224 is fitted over the soft pad 222, with its outer surface conforming to the side of the sole 6. During abrasion resistance testing of the sole 6, the abrasion-resistant sleeve 224 directly contacts the sole 6, bearing the friction between the sole 6 and the clamping head 22. Made of abrasion-resistant material, the abrasion-resistant sleeve 224 effectively reduces wear during friction with the sole 6, protects the soft pad 222 from excessive wear, further extends the service life of the clamping head 22, and ensures effective clamping of the sole 6.

[0039] Furthermore, such as Figure 1 , Figure 3 As shown, the pad 222 has an inwardly concave arc structure that fits against the side protrusion of the sole 6.

[0040] The pad 222 is designed with an inwardly concave arc structure, allowing it to conform to the side protrusions of the sole 6. When clamping the sole 6, this conformation increases the contact area between the clamping head 22 and the sole 6, resulting in a more uniform clamping force on the sole 6 in all directions. This improves clamping stability, prevents the sole 6 from shaking or slipping during testing, ensures the accuracy of test results, and better adapts to soles 6 of different shapes, enhancing the versatility of the clamp.

[0041] Furthermore, such as Figure 1 , Figure 3 As shown, the bottom of the support component 3 is driven to move up and down by the lifting component 5. The lifting component 5 is a lifting cylinder. The bottom end of the lifting cylinder is fixed to the bottom inner wall of the base 1, and the top output shaft of the lifting cylinder is connected and fixed to the bottom of the support component 3.

[0042] The bottom of the support component 3 is driven to move up and down by the lifting component 5, which is a lifting cylinder. Its bottom end is fixed to the bottom inner wall of the base 1, and its top output shaft is connected and fixed to the bottom of the support component 3. When the lifting cylinder works, the output shaft extends or retracts, causing the support component 3 to rise or fall. The height of the support component 3 can be flexibly adjusted according to the thickness and shape of different shoe soles 6, so that the shoe sole 6 is in a suitable position for testing, which improves the adaptability of the fixture to different shoe soles 6 and ensures that the shoe sole 6 remains stable during testing.

[0043] Furthermore, such as Figure 1 As shown, the top center of the support component 3 is a flat structure, which horizontally supports the bottom of the shoe sole 6.

[0044] The top center of the support component 3 is a flat structure that contacts the bottom of the sole 6, providing horizontal support for the sole 6. This ensures that the sole 6 is placed stably on the support component 3, guaranteeing uniform force distribution on the bottom of the sole 6 during testing. It also prevents excessive localized force on the sole 6 due to uneven support, which could affect the test results and further improve the accuracy and reliability of the test.

[0045] Furthermore, such as Figure 1 As shown, the driving component 4 is a driving cylinder, which is horizontally fixed inside the base 1 by a bracket, and the end of the driving cylinder abuts against the bottom end of the clamping component 2.

[0046] The driving component 4 is a driving cylinder, which is horizontally fixed inside the base 1 by a bracket. The end of the cylinder abuts against the bottom end of the clamping component 2. When the driving cylinder is working, the end extends or retracts, pushing or pulling the lower end of the clamping component 2, causing it to rotate around the pin 23. The driving cylinder can provide a stable and controllable driving force, precisely controlling the movement of the clamping component 2, thereby achieving precise control of the clamping force on the shoe sole 6, ensuring the stability and reliability of the clamping operation.

[0047] When using the anti-damage clamping structure of the shoe sole abrasion tester of this utility model, the shoe sole 6 to be tested is first placed on the base 1, so that the bottom of the shoe sole 6 contacts the flat structure in the middle of the top of the support component 3. At this time, according to the thickness and shape of the shoe sole 6, the lifting component 5 is activated, and its output shaft drives the support component 3 to rise or fall, adjusting the shoe sole 6 to a suitable testing height and ensuring that the shoe sole 6 is in a horizontal and stable state.

[0048] The drive unit 4 is activated, causing the end of the drive cylinder to extend or retract, pushing or pulling the lower end of the clamping unit 2. Since the middle of the clamping unit 2 is rotatably connected to the base 1 via a pin 23, under the action of the driving force, the clamping unit 2 rotates around the pin 23. Utilizing the lever principle, this drives the upper clamping head 22 to move towards and press against the side of the sole 6. During clamping, the soft pad 222 of the clamping head 22 contacts the side of the sole 6. When pressure is applied, the soft pad 222 compresses the internal spring 223, causing the spring 223 to undergo elastic deformation, buffering the clamping force and preventing damage to the sole 6. Simultaneously, the inwardly concave arc-shaped soft pad 222 fits against the protrusion on the side of the sole 6, increasing the contact area and distributing the clamping force evenly, ensuring that the sole 6 is firmly and stably clamped.

[0049] After the sole 6 is clamped and fixed, the testing program of the sole abrasion tester is started. The sole 6 and abrasion test components such as the grinding wheel begin to move relative to each other to conduct the abrasion test. During the test, the abrasion sleeve 224 directly contacts the side of the sole 6 and bears the friction between them. Because it is made of abrasion-resistant material, it can effectively reduce its own wear and protect the internal pad 222 and clamping head 22. At the same time, the support component 3 continuously provides stable horizontal support for the sole 6, ensuring that the sole 6 will not wobble due to uneven force during the test, thus ensuring the accuracy of the test results.

[0050] After the abrasion resistance test is completed, the drive component 4 reverses its movement, causing the clamping component 2 to release the clamping head 22 from the sole 6. Then, the lifting component 5 retracts its output shaft, causing the support component 3 to descend, making it easier for the operator to remove the tested sole 6, thus completing a full test process.

[0051] Finally, it should be noted that the electronic components in the drive component 4, lifting component 5, etc. in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
