Description
Technical Field
[0001] The present invention relates to the technical field of torque testing equipment, and in particular to a sole torque testing equipment. Background Art
[0002] As footwear quality requirements continue to rise, especially for specialized functional shoes like athletic shoes, hiking boots, and work shoes, the durability and comfort of soles have become crucial factors in evaluating footwear performance. Torsional performance, which refers to the sole's ability to twist under external forces, directly impacts the shoe's stability, comfort, and service life. Therefore, scientifically and accurately testing sole torsional performance has become a key concern for footwear manufacturers and R&D institutions.
[0003] Currently, the testing of sole torque performance mostly relies on manual operation or traditional mechanical testing equipment. In the existing technology, the sole torque test is generally carried out in the following ways:
[0004] 1. Manual torque friction structure: It is greatly affected by human factors, is time-consuming and labor-intensive, has extremely low efficiency, and cannot obtain any data;
[0005] 2. Electric rotary torsional friction structure: The friction surface and friction direction are single, the efficiency is extremely low, and no data can be obtained;
[0006] 3. Electric cam swing arm torque friction structure: The friction surface is single, the friction force cannot be adjusted, and no data can be obtained. At the same time, a large amount of power equipment is occupied for auxiliary operation, which increases the overall use and installation cost, causing many inconveniences and affecting normal detection needs.
[0007] Therefore, the present invention provides a sole torque testing device. Summary of the Invention

[0016] As a preferred embodiment, a movable groove is provided on the top of the cam movable bracket, and a buffer pad is installed inside the movable groove. The buffer pad is installed by providing the movable groove on the top of the cam movable bracket.

[0034] In this solution, a torque sensor is installed on the output shaft of the torsion spring 8, and a test sole is installed on the other end of the torsion spring 8 and above the test mounting groove 12. When the sole is fixed and subjected to the torsion test, the torsion spring 8 can continuously provide a uniform torque through its elastic characteristics. The torsion spring 8 can continuously apply or adjust the torque according to the set requirements, simulating the torsional force of the sole during walking, running, turning and other actions. The detection data is sent to the external display device in time through the torque sensor for viewing. The overall structure is simple and easy to operate, and no large amount of electrical equipment is used to assist the operation, saving the overall use and installation cost.

[0041] Working principle:
[0042] like Figure 1-Figure 3 As shown:
[0043] By setting the test shaft core 1, the cam movable bracket 2 and the cam 3, the torque sensor is controlled and processed through an external display device during use. The torque sensor model is the FUTEK TFF500 series, which is a small and high-precision torque sensor commonly used for precision measurement and torque testing. It has the characteristics of low noise, high precision and fast response, and is suitable for accurate measurement in sole torque testing.
[0044] A test sole is installed at the other end of the torsion spring 8 and above the test mounting groove 12. When the sole is fixed and subjected to the torsion test, the torsion spring 8 can continuously provide a uniform torque through its elastic characteristics. The torsion spring 8 can continuously apply or adjust the torque according to the set requirements, simulating the torsional force of the sole during walking, running, turning and other actions. The detection data is sent to the external display device in time through the torque sensor for viewing. The small washer 5 is located on one side of the spring washer 4. The spring washer 4 and the small washer 5 are used to provide a buffering and protective effect when the anti-slip nut 6 and the positioning screw 14 are installed.
[0045] The limiting step 11 is used to reinforce the connection between the test shaft core 1 and the positioning screw 14. The inside of the cam 3 and the connecting plate 22 are both provided with a concave cam structure 31 used in conjunction with the cam 3, so that the cam 3 is installed on the outside of the connecting plate 22 for use in conjunction. One end of the output shaft of the torsion spring 8 passes through the alignment groove 23 and is connected to the connecting plate 22, so as to cooperate with actual testing.
[0046] A rotating shaft is installed at the connection between the cam movable bracket 2 and the connecting plate 22, so that the connection angle of the cam movable bracket 2 and the connecting plate 22 can be manually rotated, which improves the flexibility of the equipment. A buffer pad is installed inside the movable groove 21. The movable groove 21 is opened on the top of the cam movable bracket 2 to cooperate with the buffer pad for installation, and a protective effect is played when the torsion spring 8 and the connecting plate 22 are connected through the large gasket 7.
[0047] This practical technical solution combines the advantages of the traditional electric cam swing arm torsion friction structure, and improves the shortcomings of the manual torsion friction structure that is time-consuming, labor-intensive and inefficient, while achieving its functions in a relatively low-cost manner. During the testing process, it can not only continuously test the torque friction data of different products, but also obtain real data. It can also be expanded to a fully automatic and fully intelligent working effect without the need for a lot of manpower and material resources, and can obtain important data such as real pressure, torque, speed, test time, friction torsion swing times, etc. The overall structure is simple and easy to operate, and no large amount of electrical equipment is used to assist in operation, saving the overall use and installation cost.
