The sole friction and wear tester
Technical field
The present invention relates to a kind of experimental provision, particularly relate to a kind of sole friction and wear tester.
Background technology
Shoes have long development history.In big Yangshao culture period before more than 5000 years, the most original footwear that animal skin is made have just appearred.Shoes are that the people protects pin to avoid injured a kind of instrument.People avoid pin injured or uncomfortable in order to overcome in particular cases the earliest, have just invented the fur shoes.The design of shoes and manufacturing develop into now, have progressively formed present pattern.The shoes of various pattern functions are seen everywhere.Very big variation has also taken place in the material of sole, the synthetic end of rubber and plastic, Cowhells appearred and at the bottom of, at the bottom of the PU, at the bottom of the corium etc.Be friction between sole and the ground yet human walking relies on, different figures' people is at different ground environments, and the sole abrasion is different during with different walking manner walking.Cause the wearing and tearing of sole to aggravate easily to the selection of shoes is incorrect, thereby caused the significant wastage of resource, Fei Qi shoes have also caused very big pollution to environment simultaneously.
Therefore, these those skilled in the art need design a kind of experimental provision different figure crowds sole rubbing wear situation when varying environment is walked with different walking manners is simulated, realization is to the experiment of sole rubbing wear, for the manufacturing of shoes provides the data support.
Summary of the invention
Purpose of the present invention provides a kind of sole friction and wear tester at above-mentioned the deficiencies in the prior art part exactly, can simulate different figure crowds sole rubbing wear situation when varying environment is walked with different walking manners, thereby solve above-mentioned prior art problems fully.
The objective of the invention is to realize in the following way: a kind of sole friction and wear tester, comprise the experiment table base, experiment table, support, controlled normal pressure cylinder, air cylinder connecting rod, slide plate, drive motor, torque sensor, shoe tree, resilient material, shoe tree connecting link and sample clamp device, described experiment table and support are arranged on the experiment table base, the sample clamp device is installed on the experiment table, controlled normal pressure cylinder is fixed in a top of the trellis, be provided with vertical guide at support, slide plate slides is engaged on the guide rail and by air cylinder connecting rod and is connected with controlled normal pressure cylinder, drive motor is installed on the slide plate, along its main shaft circumference some shoe tree connecting links are set evenly, shoe tree connecting link end is provided with shoe tree, the shoe tree bottom arranges resilient material, and torque sensor is fixed on the slide plate and is connected with the drive motor main shaft.
Further, at the experiment table base transition backing plate is set, experiment table is installed on the transition backing plate by the controlled angular displacement cylinder of four symmetrical distributions.
Further, the angular displacement sensor that is used for experiments of measuring platform inclination angle is installed on the described rebound.
Further, at experiment table the sample backing plate is set, the sample backing plate is provided with the guiding sliding tray, and the corresponding guiding of sample clamp device sliding tray is arranged on the sample backing plate.
Further, the uniform threaded hole of described shoe tree link, the shoe tree connecting link is threaded with shoe tree, the angle between adjustable shoe shoe last or hat block and the shoe tree connecting link.
Further, described experiment table base end face is equipped with levelling bolt.
Compared with prior art, beneficial effect of the present invention is: can simulate different figure crowds sole rubbing wear situation when varying environment is walked with different walking manners, realization is to the experiment of sole rubbing wear, can be different crowd selects shoes that the data support is provided, also can be shoemaking producer when producing shoes at zones of different, select suitable material for sole of shoe that the data support is provided.And, effectively reduce sole abrasion, prolong shoes serviceable life, and then reduce to the pollution of environment with to the waste of resource.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, a kind of sole friction and wear tester, comprise experiment table base 13, experiment table 20, support 10, controlled normal pressure cylinder 4, air cylinder connecting rod 5, slide plate 7, drive motor 9, torque sensor 8, shoe tree 1, resilient material 2, shoe tree connecting link 3 and sample clamp device 16, described support 10 is fixed on the experiment table base 13 by trip bolt 11, at experiment table base 13 transition backing plate 15 is set, experiment table 20 is installed on the transition backing plate 15 by the controlled angular displacement cylinder 18 of four symmetrical distributions, the angular displacement sensor 14 that is used for experiments of measuring platform 20 inclination angles is installed on the described rebound 15, at experiment table 20 sample backing plate 21 is set, sample backing plate 21 is provided with guiding sliding tray 19, sample clamp device 16 corresponding guiding sliding trays 19 are arranged on the sample backing plate 21, controlled normal pressure cylinder 4 is fixed in support 10 tops, be provided with vertical guide 6 at support 10, slide plate 7 is slidingly fitted on the guide rail 6 and by air cylinder connecting rod 5 and is connected with controlled normal pressure cylinder 4, drive motor 9 is installed on the slide plate 7, along its main shaft circumference some shoe tree connecting links 3 are set evenly, shoe tree connecting link 3 ends are provided with shoe tree 1, shoe tree 1 bottom arranges resilient material 2, and torque sensor 8 is fixed on the slide plate 7 and is connected with drive motor 9 main shafts.
The uniform threaded hole 22 of described shoe tree 1 link, shoe tree connecting link 3 is threaded with shoe tree 1, and different threaded holes 22 connect on shoe tree connecting link 3 and the shoe tree 1 by adjusting, and can make shoe tree 1 generation certain angle.Described experiment table base 13 bottom surfaces are equipped with levelling bolt 12.
In use, experimental sample 17 is fixed on the sample backing plate 21 by sample clamp device 16, and sole and ground contacted pressure and contact condition when the lifting by controlled normal pressure cylinder 4 and the distortion of shoe tree 1 bottom resilient material 2 came maximum anthropomorphic dummy to walk; Simulate the andfrictional conditions of sole and Different Ground material under the different speeds of travel by the rotating speed of control drive motor 9; Lifting by controlled angular displacement cylinder 18 realizes the simulation to the sole eccentric wear; By adjusting the angle of shoe tree 1 and shoe tree connecting rod 3, can simulate different people and walk gait to the situation of sole rubbing wear, as toe out and pigeon-toed etc.; By changing experimental sample 17, but the anthropomorphic dummy when the Different Ground material walk, the friction and wear characteristic of different material for sole of shoe and sole lines is tested.
Therefore, the present invention can effectively simulate the friction and wear characteristic of different crowd sole under varying environment, and experiment improves comfortableness, on-slip and the security of shoes, and this apparatus structure compactness, and complete function is convenient to realize.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
