Description

Clamp damage-proof structure of sole grinding machine Technical Field The utility model relates to the technical field of wear resistance testing of soles, in particular to a clamp damage prevention structure of a sole wear-resistant machine. Background In the technical field of sole wear resistance test, a sole wear resistance grinder is used as core equipment for evaluating the wear resistance of sole materials, and the test precision of the sole wear resistance grinder is closely related to the performance of a clamp. For example, china patent application number 202311309661.8 discloses a sole wear-resistant testing device and a method thereof, and the device utilizes a spring to provide elasticity to enable the sole to be clung to a polishing wheel in the testing process by arranging a supporting mechanism, so that the normal running of the testing is ensured to a certain extent. However, there are a number of disadvantages to the prior art. Above-mentioned fixed subassembly among the comparison document, its positioning mechanism is comparatively single to the centre gripping mode of sole, mainly relies on supporting mechanism's elasticity to realize the laminating of sole and grinding wheel, is difficult to carry out accurate stable fixed to the sole of different shapes, size. In the testing process, if the sole is irregular in shape or large in size difference, shaking or uneven local stress is easy to occur, so that the accuracy of a testing result is affected, abnormal wear of the sole is possibly caused, and the wear resistance of the sole material cannot be truly reflected. In addition, the contact part of the clamp and the sole of the device lacks an effective damage prevention design, under the high-frequency friction test, the rigid contact between the clamp and the sole easily causes rapid abrasion of the surface of the clamp, the service life of the clamp is shortened, the maintenance cost of equipment is increased, and meanwhile, the surface of the sole is possibly damaged due to excessive extrusion of the clamp on the sole, so that the reliability of test data is interfered. Therefore, there is a need to design a sole grinder-resistant clamp damage-preventing structure which can be adapted to various soles, effectively reduce clamp abrasion and improve test precision.
