DETAILED DESCRIPTION

[0023] The present application is further described in detail below in combination with the drawings and examples. The same parts are indicated by the same figure mark.

[0024] As shown in the drawings, Figs. 1-3 A shoe sole support performance automatic testing device comprises a machine tool 1, a test surface 2 is formed on the machine tool 1, the machine tool 1 is provided with a detection station 3 corresponding to the test surface 2, and the machine tool 1 is provided with a constraint unit 4 on both sides corresponding to the detection station 3, and the two constraint units 4 are used for respectively abutting and constraining the two ends of the shoe sole.

[0025] In use, the shoe is placed on the test surface 2, so that the two constraint units 4 respectively abut and constrain the two ends of the shoe sole, thereby completing the installation of the shoe detection.

[0026] Further comprising a pressing unit 5, the pressing unit 5 is arranged corresponding to the detection station 3, the pressing unit 5 comprises a driving source 6 and a pressing rod 7, the end of the pressing rod 7 is provided with a pressure sensor 8, and the driving source 6 is connected with the pressing rod 7 and is used for driving the pressing rod 7 to ascend and descend.

[0027] Specifically, the driving source 6 is a pneumatic cylinder, a connecting frame is arranged on the machine tool 1 and connects the pneumatic cylinder, the output end of the pneumatic cylinder is connected with the pressing rod 7 and is used for driving the pressing rod 7 to ascend and descend, so as to enter the shoe from the shoe opening and abut the shoe sole.

[0028] Further, the end of the pressing rod 7 is provided with a pressure sensor 8, and the detection port of the pressure sensor 8 is in contact with the shoe sole to detect the pressure value of the pressing rod 7 on the shoe sole.

[0029] The displacement detection unit 9 is arranged corresponding to the detection station 3, and the lower pressing rod 7 moves downward to contact the shoe sole and make the shoe sole deform downward, and the displacement detection unit 9 is used to detect the displacement of the shoe sole along the height direction before and after the deformation.

[0030] Specifically, the displacement detection unit 9 is a displacement measuring device, and the distance measurement is completed by using laser. In use, the laser distance measuring sensor detects the initial value of the shoe sole position, and then the cylinder drives the lower pressing rod 7 to press downward. When the pressure sensor 8 detects the pressure, it is considered that the lower pressing rod 7 contacts the shoe sole. At this time, the cylinder drives the distance to obtain the thickness value of the shoe sole and the vertical distance between the stress position of the shoe sole and the test surface. Then the cylinder continues to drive the lower pressing rod 7 to move and contact the shoe sole and make the shoe sole deform downward. The deformation value of the shoe sole under the specified pressure is detected by the pressure sensor, so as to obtain the support performance data of the shoe sole.

[0031] Preferably, the lower pressing rod 7 is provided with an arc detection unit 10, and the arc detection unit 10 includes two detection groups 11 symmetrically arranged on both sides of the end of the lower pressing rod 7. Each detection group 11 includes a plurality of detection units rotatably connected with each other, and an angular displacement sensor 12 is arranged at the rotatable connection position of the detection units. The angular displacement sensor 12 is used to detect the relative rotation angle of adjacent detection units.

[0032] In use, the detection group 11 enters the shoe along with the lower pressing rod 7, and is manually laid on the shoe sole surface. At this time, the angular displacement sensor 12 records the initial value, and after the lower pressing rod 7 is pressed, the adjacent detection units are moved along with the movement of the lower pressing rod 7, so that the plurality of detection units can naturally form an arc line matched with the deformation arc of the shoe sole, and the rotation angle of the adjacent detection units is recorded by the angular displacement sensor 12, so as to realize the detection of the arc after the deformation of the shoe sole.

[0033] Since the scheme of relative rotation of a plurality of detection units is adopted for angle detection, a plurality of detection points can be formed to realize arc detection.

[0034] Since the shoe sole generally has uneven height, the detection units arranged in the shoe to detect the arcs before and after the deformation of the shoe sole can ensure the detection accuracy and avoid the influence of the uneven height of the shoe sole on the detection result.

[0035] Preferably, the detection unit includes a main body 13, and the two ends of the main body 13 are respectively formed with a connecting end 14 and a detection end 15. The main body 13 is symmetrically provided with a connecting seat 16 corresponding to the connecting end 14. The two connecting seats 16 are both provided with a rotating rod 17 at the end close to each other. The main body 13 is outwardly extended to form a mounting portion 18 corresponding to the detection end 15. The mounting portion 18 is provided with a rotating hole 19 corresponding to the two rotating rods 17 and connected with the rotating rods 17. The angular displacement sensor 12 is arranged in the mounting portion 18. The rotating rod 17 is inserted into the rotating hole 19 and connected with the angular displacement sensor 12.

[0036] The connection scheme of the rotating rod 17 and the mounting portion 18 can make the adjacent main bodies 13 more compact, thereby shortening the length of the adjacent main bodies 13 to provide more detection points and improve the accuracy of arc detection.

[0037] Preferably, at least one side of the mounting portion 18 is provided with a detection hole 20 and a detection column 21 is rotatably arranged, the detection end 15 of the angular displacement sensor 12 is fixed to the detection column 21, the rotating hole 19 is a hole corresponding to one side of the mounting portion 18 in the axial direction, and the rotating hole 19 is a non-circular hole, and the rotating rod 17 is shaped to match the rotating hole 19.

[0038] Specifically, the rotating hole 19 is a rectangle.

[0039] The detection column 21 is arranged to facilitate connection with the angular displacement sensor 12, and the non-circular rotating hole 19 facilitates connection and limiting with the rotating rod 17, so that the rotating rod 17 drives the detection column 21 to rotate, thereby realizing the relative rotation of the rotating rod 17 and the mounting portion 18.

[0040] Preferably, the connecting seat 16 is provided with a through hole 22, the rotating rod 17 includes a limiting head 23, a limiting rod 24 and a connecting rod 25, the two ends of the limiting rod 24 are respectively connected to the limiting head 23 and the connecting rod 25, the through hole 22 is a non-circular hole, the limiting rod 24 is shaped to match the through hole 22, when the rotating rod 17 is connected to the through hole 22, the limiting head 23 abuts against one side of the connecting seat 16, the limiting rod 24 is connected to the through hole 22 and limits the rotation of the limiting rod 24 relative to the through hole 22, and the connecting rod 25 is inserted into the rotating hole 19 and matched with the rotating hole 19.

[0041] The limiting head 23, the limiting rod 24 and the connecting rod 25 are arranged to facilitate the connection and separation of the rotating rod 17 and the through hole 22, so that the operator can adjust the length of the detection group 11 according to the detection needs to meet different detection needs.

[0042] Preferably, the constraint unit 4 is a movable baffle, the machine tool 1 is provided with a sliding groove 26, the sliding groove 26 is provided with a sliding rod 27 in the length direction, the lower end of the movable baffle is limited to slide in the sliding groove 26, and the movable baffle is provided with a sliding hole corresponding to the sliding rod 27 and is limited to slide with the sliding rod 27, the sliding rod 27 is wound with a spring 28, and the two ends of the spring 28 abut against the sliding groove 26 and the movable baffle respectively and are used to drive the movable baffle to move towards the detection station 3.

[0043] Since the shoe sole will be deformed in arc shape under the force of the pressing rod 7 during pressing, the two ends of the shoe sole will exert force on the movable baffle, therefore, the spring 28 is used to drive the movable baffle, which can avoid rigid fixing of the shoe, so that the shoe can complete natural deformation through the movement of the movable baffle, to ensure the experimental precision.

[0044] Since the spring 28 is used to drive the movable baffle, the spacing between the two movable baffles can be infinitely adjusted, so that the adaptation ability to different types of shoe soles can be greatly improved.

[0045] Preferably, the detection station 3 is a test hole arranged on the test surface 2, and the pressing unit 5 and the displacement detection unit 9 are arranged on the upper and lower sides of the test hole 20 respectively, wherein the pressing unit 5 and the displacement detection unit 9 are fixedly connected with the machine tool 1 through the support.

[0046] The arrangement of the test hole can ensure that the positions of the pressing unit 5 and the displacement detection unit 9 correspond, so as to provide a better detection environment for the displacement detection unit 9, to improve the detection precision.
