Description

Technical Field

[0001] This utility model relates to the technical field of shoe testing equipment, specifically a flexural endurance tester with a shoe-shaped fixed calibration structure. Background Technology

[0002] The whole shoe flexure tester (flexural strength tester) is used to test the flexural strength of shoes. It mainly tests the upper and sole by performing flexure tests at a specified angle and frequency. After reaching the specified number of flexures, the changes in the sole are measured and observed.

[0003] A search revealed a patent document, CN202221400237.5, which discloses "a shoe flexural endurance testing device." This device includes a base plate and a shoe body to be tested. One end of the base plate is equipped with a toe-fixing component. This component, with adjustable height, presses the toes of different types of shoes. An adjustable horizontally moving cam-pressing component reciprocates the pressing of the heel-pressing plate, causing the heel-pressing plate to bend repeatedly under the stress and gravity of the shoe body. This achieves the flexural endurance test of the shoe body. By adjusting the pressing contact points of the cam-pressing component on the heel-pressing plate, the shoe body can bend at different angles, improving the diversity and accuracy of the simulated data.

[0004] This patent has some problems in actual use. When testing shoes, it can only effectively compress and fix the toe, without limiting the heel or covering the sides of the shoe. During the up-and-down swinging of the heel compression plate, the shoe is prone to displacement due to vibration, friction and other factors, which changes the original test area of ​​the shoe's flexural strength, resulting in distorted test data that cannot accurately reflect the actual flexural strength of the shoe. To address these issues, we propose a flexural strength testing machine with a shoe shape fixing and calibration structure to solve the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this invention is to provide a flexural endurance testing machine with a shoe-shaped fixed calibration structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flexural endurance testing machine with a shoe-shaped fixed calibration structure, comprising a base plate, a flip support platform and a fixed support platform respectively mounted on the top of the base plate, a servo calibration mechanism mounted on the top of the base plate at a position corresponding to the position between the flip support platform and the fixed support platform, a test piece positioning mechanism mounted on the top of both the flip support platform and the fixed support platform, and a drive mechanism for intermittent rotation of the flip support platform mounted on the top of the base plate.

[0007] Furthermore, the servo calibration mechanism includes a first motor mounting platform, on which a first motor is fixedly mounted. A bidirectional screw is fixedly connected to the output shaft end of the first motor. Lateral calibration components are threaded along the axial direction on both the forward and reverse thread portions of the bidirectional screw. A bearing seat is mounted on the end of the bidirectional screw away from the first motor, and the bearing seat is fixedly connected to the top of the substrate.

[0008] Furthermore, the lateral calibration component includes a transverse block, which is threadedly connected to the surface of the bidirectional screw along the axial direction. A vertical plate is fixedly installed on the top of the transverse block, and a calibration stop is installed on the side of the vertical plate away from the first motor. A guide slider is fixedly installed on the bottom of the transverse block, and the guide slider is slidably connected in a guide groove on the top of the substrate.

[0009] Furthermore, the test piece positioning mechanism includes a standing block, on which an mounting block is connected via a cylinder. A clamping seat is fixedly connected to the side of the mounting block away from the cylinder via bolts. A threaded sleeve is welded to the top of the mounting block via a bracket. A rotating bolt is internally threaded onto the threaded sleeve. A circular rotating plate is fixedly connected to the bottom end of the rotating bolt. A covering sleeve is movably connected to the outer surface of the circular rotating plate. A guide slide is fixedly connected to the outer side of the covering sleeve.

[0010] Furthermore, a support frame is mounted on the top of the substrate, a fixed shaft is welded onto the support frame, and a rotating seat is fixedly connected to the bottom of the flip support platform, the rotating seat being rotatably connected to the fixed shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

Combined with the lateral positioning of the servo calibration mechanism, it realizes all-round fixation and calibration of the shoes, avoiding displacement of the shoes due to vibration, friction and other factors during the intermittent rotation of the flip support platform, and ensuring the smooth progress of the flexural endurance test.

[0015] 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.

[0016] Please see Figure 1-4 A flexural endurance testing machine with a shoe-shaped fixed calibration structure includes a base plate 1. A flip support platform 2 and a fixed support platform 3 are respectively installed on the top of the base plate 1. A certain distance is provided between the flip support platform 2 and the fixed support platform 3, and the two respectively support and place the shoe heel and shoe toe. A servo calibration mechanism 4 is installed on the top of the base plate 1 at the position between the flip support platform 2 and the fixed support platform 3. A test piece positioning mechanism 5 is installed on the top of both the flip support platform 2 and the fixed support platform 3. A drive mechanism 6 for intermittent rotation of the flip support platform 2 is also installed on the top of the base plate 1.

[0017] The servo calibration mechanism 4 includes a first motor mounting platform 41, on which a first motor 42 is fixedly mounted. The first motor 42 is a servo motor, powered by a battery or an external power source. A bidirectional screw 43 is fixedly connected to the output shaft end of the first motor 42. Lateral calibration components 44 are axially threaded onto both the forward and reverse threaded portions of the bidirectional screw 43. A bearing seat is mounted on the end of the bidirectional screw 43 away from the first motor 42, and the bearing seat is fixedly connected to the top of the base plate 1. The bearing seat can connect and support the end of the bidirectional screw 42, thereby improving its rotational stability. The servo calibration mechanism 4 can calibrate and position the shoe from both sides. By driving the bidirectional screw 43 to rotate through the first motor 42, the two lateral calibration components 44 move closer or further apart, thereby adapting to shoes of different widths and ensuring that the shoe will not shift due to lateral force during testing, thus improving the accuracy of the test.

[0018] The lateral calibration component 44 includes a transverse block 441, which is threadedly connected to the surface of the bidirectional screw 43 along the axial direction. A vertical plate 442 is fixedly installed on the top of the transverse block 441. A calibration stop 443 is installed on the side of the vertical plate 442 away from the first motor 42. A guide slider 444 is fixedly installed on the bottom of the transverse block 441. The guide slider 444 is slidably connected in the guide groove on the top of the base plate 1. The cooperation between the guide slider 444 and the guide groove guides the movement of the transverse block 441, ensuring that the transverse block 441 can move stably and accurately under the drive of the bidirectional screw 43. This allows the calibration stop 443 to accurately contact the side of the shoe and achieve effective calibration. The calibration stop 443 can be made of a material with a certain elasticity, such as rubber. Its contact surface with the shoe is an arc-shaped surface to avoid damage to the shoe when in contact with it.

[0019] The test piece positioning mechanism 5 includes a stand block 51. A mounting block 53 is connected to the stand block 51 via a cylinder 52. A clamping seat 54 is bolted to the side of the mounting block 53 away from the cylinder 52. The clamping seat 54 is detachable, allowing for the replacement of different clamps according to the type of test shoe, thus improving adaptability. A threaded sleeve 55 is welded to the top of the mounting block 53 via a bracket. A rotating bolt 56 is threaded into the threaded sleeve 55. A circular rotating plate 57 is fixedly connected to the bottom end of the rotating bolt 56. A covering sleeve 58 is movably connected to the outer surface of the circular rotating plate 57. A guide slide 59 is fixedly connected to the outer side of the covering sleeve 58. One end of the guide slide 59 is slidably connected in a guide groove on the outer surface of the threaded sleeve 55. Two test piece positioning mechanisms 5 can clamp the toe and heel of the shoe relative to each other and fix the shoe from the top and bottom. The cylinder 52 can drive the mounting block 53 to move horizontally, thereby driving the clamping seat 54 to move horizontally to adapt to the clamping limit of shoes of different lengths. After the rotating bolt 56 is rotated, it can drive the circular rotating plate 57 to move vertically. Under the limit of the guide slide 59, the rotating circular rotating plate 57 can drive the covering sleeve 58 to move vertically. The covering sleeve 58 on the flip support platform 2 extends into the shoe hole and is pressed down and fixed from the heel. The covering sleeve 58 on the fixed support platform 3 can be pressed down and fixed from the toe, further ensuring the stability of the shoe fixation.

[0020] A support frame 7 is mounted on the top of the base plate 1. The support frame 7 adopts a U-shaped structure. A fixed shaft 8 is welded on the support frame 7. A rotating seat 9 is fixedly connected to the bottom of the flip support platform 2. The rotating seat 9 is rotatably connected to the fixed shaft 8. The cooperation of the support frame 7, the fixed shaft 8 and the rotating seat 9 provides stable support for the rotation of the flip support platform 2, ensuring that the flip support platform 2 can smoothly rotate intermittently under the drive of the drive mechanism 6, so as to realize the flexural resistance test of the shoe.

[0021] The drive mechanism 6 includes a second motor mounting platform 61, which is fixedly mounted on the top of the base plate 1. A second motor 62 is fixedly mounted on the second motor mounting platform 61. The second motor 62 is an adjustable speed motor, powered by a battery or an external power source. A camshaft 63 is fixedly connected to the output shaft end of the second motor 62. A pressing cam 64 is fixedly connected to the surface of the camshaft 63. One end of the pressing cam 64 has an opening, and a lubricating roller 65 is installed in the opening. The lubricating roller 65 can prevent the end of the pressing cam 64 from directly contacting the bottom of the flip support platform 2 during rotation, thus preventing excessive wear. The second motor 62 drives the camshaft 63 to rotate, which in turn drives the pressing cam 64 to rotate. During rotation, the pressing cam 64 intermittently presses the flip support platform 2 to rotate around the fixed axis 8, thereby achieving repeated bending of the shoe and simulating the bending situation of the shoe during actual wear, completing the bending resistance test. A bearing seat is installed at one end of the camshaft 63, and the bearing seat is fixedly connected to the top of the base plate 1, which can realize the connection support of the camshaft 63 and improve its stability during rotation.

[0022] In use, the shoe to be tested is first placed on the flip support platform 2 and the fixed support platform 3. Based on the width of the shoe, the first motor 42 is started, driving the bidirectional screw 43 to rotate. The bidirectional screw 43 drives the two lateral calibration components 44 to move closer together, so that the calibration stops 443 contact the sides of the shoe, completing the lateral calibration. Then, the cylinder 52 is started, pushing the mounting block 53 to move horizontally. The two clamping seats 54 clamp the toe and heel of the shoe respectively. After the rotating bolt 56 is rotated, it can drive the circular rotating plate 57 to move vertically. Under the limit of the guide slide 59, the rotating circular rotating plate 57 can drive the covering... The sleeve 58 is moved vertically, and the sleeve 58 on the flip support platform 2 extends into the shoe and is pressed down and fixed from the heel. The sleeve 58 on the fixed support platform 3 can be pressed down and fixed from the toe. After fixing, the second motor 62 is started. The second motor 62 drives the camshaft 63 to rotate, and the camshaft 63 drives the compression cam 64 to rotate. The compression cam 64 intermittently compresses the flip support platform 2 to rotate around the fixed axis 8, realizing repeated bending of the shoe, simulating the bending of the shoe in the actual wearing process, and completing the bending resistance test. During the test, the servo calibration mechanism 4 and the test piece positioning mechanism 5 can ensure that the shoe will not shift, ensuring the accuracy of the test.
