Description

Technical Field

[0001] This invention relates to the field of insole compression resistance testing technology, and specifically to an insole compression strength tester. Background Technology

[0002] Insoles not only enhance shoe comfort but also contribute to improving foot health, preventing foot fatigue, and alleviating foot ailments. To ensure insole quality, especially its ability to withstand external forces during use, compressive strength has become a crucial indicator of insole performance. Insole compressive strength refers to the insole's ability to withstand a certain amount of external force without damage or permanent deformation under pressure.

[0003] A utility model patent (publication number: CN2754085Y) discloses an insole compressive strength tester, which includes a heated testing chamber. The temperature of the heating element inside the chamber can be adjusted and maintained by a switch regulator mounted on the outer shell of the testing chamber. The testing chamber contains an insole compressive strength testing frame, which consists of four sliding rods fixed to the upper and lower chamber plates, upper and lower fixing plates fitted onto them, upper and lower pressure plates, and a lower power plate. The lower power plate is driven by a power piston located in the middle below it. Each sliding rod between the upper fixing plate and the lower pressure plate is equipped with a constant pressure spring device. The heating element is installed between the lower power plate and the lower pressure plate, and the insole sample is placed between the upper and lower pressure plates. This application uses overall compressive strength testing, which cannot reveal the differences in compressive strength between different areas of the insole. For example, during later wear, the forefoot and heel areas experience greater stress and are prone to deformation. Overall testing ignores these localized usage characteristics of the insole, thus failing to comprehensively assess the actual performance of the insole.

[0004] Currently, a static compression tester for insoles is commonly used to test the compression deformation of the forefoot and heel. The specific steps are as follows: (1) The sample is a pair of insoles. The sample should not have defects, impurities and contamination, and the surface of the sample should be as flat as possible.

[0005] Place the insole on a horizontal surface against a vertical surface, with the vertical surface contacting the inner edge of the insole at points A and B. Then, place two more vertical surfaces perpendicular to the first vertical surface, contacting the insole at points X and Y. These two points are the toe point and heel point, respectively. Connect points X and Y with a straight line to form the central axis of the insole, i.e., the inner length XY. Figure 7 As shown.

[0006] For the forefoot test area, the distance from the test center point C to the heel point is 75% of the inner length XY of the test sample; for the heel test area, the distance from the test center point D to the heel point is 12% of the inner length XY of the test sample.

[0007] After confirming the test point, mark a circle with the same diameter as the pressure head on the front of the insole, centered on the test point. This circle is the test area. Figure 7 As shown.

[0008] The existing equipment not only has cumbersome testing procedures, but also requires manual measurement to determine the test points. This is fine if the same product is being tested, but if a large number of insoles of different specifications need to be tested, they need to be adjusted individually before each test, resulting in low testing efficiency and large errors due to manual adjustment.

The outer sides of the drive shaft, driven shaft one, and driven shaft two are all provided with helical guide grooves. The drive rod and the slide frame are all provided with shaft holes. The inner wall of the shaft hole is provided with a guide block. The drive shaft passes through the shaft hole on the drive rod, and driven shaft one and driven shaft two pass through the shaft holes in the two sets of slide frames respectively. The guide block is inserted into the corresponding helical guide groove. The end of the drive shaft, driven shaft one, and driven shaft two away from the mounting plate is fixedly mounted with a synchronous gear. The synchronous gears on driven shaft one and driven shaft two are respectively meshed on both sides of the synchronous gear on the drive shaft.

[0013] Furthermore, the tooth ratio of the synchronous gear on the driven shaft one to the synchronous gear on the driving shaft is 4:3, the tooth ratio of the synchronous gear on the driven shaft two to the synchronous gear on the driving shaft is 25:3, and the helical spacing of the helical guide grooves on the driving shaft, driven shaft one, and driven shaft two is the same.

[0014] Furthermore, the three sets of synchronous gears have the same number of teeth, the pitch of the driven shaft one helix is ​​3 / 4 of the pitch of the driving shaft helix, and the pitch of the driven shaft two helix is ​​3 / 25 of the pitch of the driving shaft helix.

[0020] The beneficial effects of this invention are as follows: This invention utilizes an inclined storage platform and an inclined right-angle storage slot. The top plate slides along the right-angle storage slot, contacting the insole. Then, the mounting plate slides, causing a laser rangefinder sensor to move. When the laser from the first laser rangefinder sensor is completely blocked by the insole, the detection distance shortens, and the mounting plate stops sliding. This point is identified as point Y. At this point, a swing arm is controlled to swing, causing a sliding plate to slide along the top plate. The swing arm also causes a second laser rangefinder sensor to move. When the laser from the second laser rangefinder sensor is completely blocked by the insole, the detection distance shortens, and the swing arm stops swinging. This point is identified as point X. This completes the rapid positioning of points X and Y. The swing arm is aligned with the XY line, and the pressure hydraulic cylinders are located on this line. At this point, the two sets of pressure hydraulic cylinders are directly above test points C and D, enabling automatic and rapid test point positioning with high testing efficiency.

[0021] This invention utilizes the distance the slide plate travels along the pendulum to control the constant distance change of the pressurizing hydraulic cylinder, ensuring that the two sets of pressurizing hydraulic cylinders are always located at 75% and 12% of the XY line. This allows the equipment to quickly adapt to testing insoles of different specifications and is suitable for rapid testing of a large number of insoles of different specifications.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] Example 1, as Figures 1-7 As shown, a shoe insole compressive strength tester includes an insulated box 1, a bracket 2 fixedly installed inside the insulated box 1, a storage platform 3 inclinedly set on the top of the bracket 2, two sets of symmetrically distributed right-angle storage slots 31 opened on the upper surface of the storage platform 3, the right angle points of the right-angle storage slots 31 are inclined downward, and an installation platform 33 is set between the two sets of right-angle storage slots 31. Two sets of origin positioning components 4 are vertically mounted on the upper surface of the mounting platform 33. The origin positioning components 4 include a mounting plate 45 slidably connected to the mounting platform 33. A laser rangefinder sensor 46 is fixedly mounted on the lower surface of the mounting plate 45. An endpoint positioning component 6 is installed inside the right-angle storage slot 31. The endpoint positioning component 6 includes a top plate 61 slidably connected to the inside of the right-angle storage slot 31. A slide plate 63 is slidably connected to the upper surface of the top plate 61. A locking bolt 67 is threadedly connected to the outer side of the slide plate 63. A laser rangefinder sensor 64 is installed on the lower surface of the slide plate 63. A pressure application component 5 is mounted on the upper surface of the mounting plate 45. The pressure application component 5 includes a swing arm 52 rotatably mounted on the upper surface of the mounting plate 45. The swing arm 52 is connected to the slide plate 63. Two sets of sliding carriages 57 are installed inside the swing arm 52. A pressure hydraulic cylinder 58 is installed at the bottom of the carriage 57. A test pressure head 59 is fixedly mounted at the bottom of the telescopic end of the pressure hydraulic cylinder 58.

[0026] During testing, the insulated box 1 was opened, and a pair of insoles were symmetrically placed in the two sets of right-angle storage slots 31. In this embodiment, the storage platform 3 is tilted at an angle of 30°, and the right-angle storage slots 31 are also tilted at an angle of 30°. Therefore, the insoles naturally slid into the right-angle storage slots 31. Figure 7 Points AB are located on the bottom edge of the right-angle storage slot 31, and point Y is located on the side edge of the right-angle storage slot 31. At this time, simply slide the top plate 61 until it touches the top of the insole. Point X is located on the top plate 61. This quickly determines each positioning point without having to set vertical positioning surfaces one by one, reducing the number of operation steps. Then, the top plate 61 is locked in the right-angle storage slot 31 by the locking bolt 67, and the manual operation steps are completed. Close the insulation box 1 and ensure the internal temperature and humidity meet the testing requirements. Simultaneously, control the sliding of the mounting plate 45. The mounting plate 45 slides upwards along the side from the right-angle point of the right-angle storage slot 31. The mounting plate 45 drives the laser rangefinder 46 to move. The laser rangefinder 46 detects its distance from the inner wall of the right-angle storage slot 31. When the laser rangefinder 46 moves to the contact point between the insole and the right-angle storage slot 31, which is the Y-point, the laser is blocked by the insole. At this point, the detection distance decreases, and the mounting plate 45 stops sliding. The laser rangefinder 46 is now located at the Y-point, which is also the rotation center of the swing arm 52. At this point, control the swing arm 52 to swing. The swing arm 52 drives the slide plate 63 to slide along the top plate 61. The top plate 61 drives the laser rangefinder... The second laser rangefinder 64 slides along the vertical line of point X. When the second laser rangefinder 64 moves to the contact point between the insole and the top plate 61, which is point X, the laser is blocked by the insole, and the detection distance becomes smaller. The swing arm 52 stops swinging. At this time, the center line of the swing arm 52 coincides with the XY line, and the two sets of pressure hydraulic cylinders 58 are located on the XY line. Then, the two sets of pressure hydraulic cylinders 58 are controlled to slide so that they are directly above the foot test point C and the heel test point D, respectively. The pressure hydraulic cylinders 58 press on the test points through the test head 59 to perform the pressure test. It can automatically complete the test point positioning and testing, which has high testing efficiency, saves the process of manually measuring and determining the test position, eliminates the error caused by manual measurement, and has high testing accuracy.

[0027] In embodiment two, based on the above embodiment, an active slide rod 65 is rotatably mounted on the top of the slide plate 63. The rotation axis of the active slide rod 65 coincides with the center line of the laser of the laser rangefinder sensor 64. Three sets of slide grooves 521 are opened inside the swing rod 52. The active slide rod 65 is slidably connected in the middle slide groove 521. Two sets of slide frames 57 are slidably connected in the slide grooves 521 on both sides. An extension plate is provided at the bottom of the slide frame 57. A pressure hydraulic cylinder 58 is fixedly mounted on the extension plate, and the axis of the pressure hydraulic cylinder 58 passes vertically through the center line of the middle slide groove 521.

[0028] The drive shaft 53 is rotatably mounted inside the middle slide groove 521. Driven shaft 1 54 and driven shaft 2 55 are rotatably mounted in the two side slide grooves 521 respectively. The outer sides of the drive shaft 53, driven shaft 1 54 and driven shaft 2 55 are all provided with helical guide grooves. The drive rod 65 and the slide 57 are all provided with shaft holes. The inner wall of the shaft hole is provided with guide blocks. The drive shaft 53 passes through the shaft hole on the drive rod 65. Driven shaft 1 54 and driven shaft 2 55 pass through the shaft holes in the two sets of slides 57 respectively, and the guide blocks are inserted into the corresponding helical guide grooves. The end of the drive shaft 53, driven shaft 1 54 and driven shaft 2 55 away from the mounting plate 45 is fixedly mounted with a synchronous gear 56. The synchronous gears 56 on driven shaft 1 54 and driven shaft 2 55 respectively mesh with the two sides of the synchronous gear 56 on the drive shaft 53.

[0029] The tooth ratio of the synchronous gear 56 on driven shaft 1 54 to that on driving shaft 53 is 4:3. The tooth ratio of the synchronous gear 56 on driven shaft 2 55 to that on driving shaft 53 is 25:3. The helical spacing of the helical guide grooves on driving shaft 53, driven shaft 1 54 and driven shaft 2 55 is the same.

[0030] Close the insulation box 1 and ensure the internal temperature and humidity meet the testing requirements. Simultaneously, control the sliding of the mounting plate 45. The mounting plate 45 slides upwards along the side from the right-angle point of the right-angle storage slot 31. The mounting plate 45 drives the laser rangefinder 46 to move. The laser rangefinder 46 detects its distance from the inner wall of the right-angle storage slot 31. When the laser rangefinder 46 moves to the contact point between the insole and the right-angle storage slot 31, which is the Y-point, the laser is blocked by the insole. At this time, the detection distance decreases, and the mounting plate 45 stops sliding. The laser rangefinder 46 is located at the Y-point, which is also the rotation center of the swing arm 52. At this time, control the swing arm 52 to swing. The swing arm 52 swings around the Y-point. The swing arm 52 drives the slide plate 63 to slide along the top plate 61 through the active slide rod 65. Since the slide plate 63 slides in a straight line, during the swing of the swing arm 52, the active slide rod 65 is relatively close to the slide plate 63. The active slide rod 65 rotates and slides along the middle slide groove 521. The active slide rod 65 drives the active shaft 53 to rotate through the guide block and the spiral guide groove. The active shaft 53 drives the synchronous gear 56 to rotate. Through the gear ratio of the synchronous gear 56, the number of rotations of the driven shaft 1 54 is 75% of that of the active shaft 53. The sliding distance of the corresponding slide 57 is 75% of the sliding distance of the active slide rod 65. This makes the pressure hydraulic cylinder 58 at this position automatically located at 75% of the XY line, which is point C. At the same time, the number of rotations of the driven shaft 2 55 is 12% of that of the active shaft 53. The sliding distance of the corresponding slide 57 is 12% of the sliding distance of the active slide rod 65. This makes the pressure hydraulic cylinder 58 at this position automatically located at 12% of the XY line, which is point D. Therefore, this embodiment can automatically adjust the two sets of pressure hydraulic cylinders 58 to be located at points C and D, which can be quickly applied to the testing of insoles of different specifications and has high testing efficiency.

[0031] Example 3, based on the above examples, further includes three sets of synchronous gears 56 with the same number of teeth, the helical pitch of driven shaft 1 54 being 3 / 4 of the helical pitch of driving shaft 53, and the helical pitch of driven shaft 2 55 being 3 / 25 of the helical pitch of driving shaft 53.

[0032] In this embodiment, by making the driving shaft 53, driven shaft 1 54 and driven shaft 2 55 rotate at the same speed, and utilizing the difference in their helical pitch, under the same rotational speed, the sliding distance of the slide 57 corresponding to driven shaft 1 54 is 75% of the sliding distance of the driving slide 65, so that the pressurized hydraulic cylinder 58 at this position is automatically located at 75% of the XY line, which is point C. At the same time, the sliding distance of the slide 57 corresponding to driven shaft 2 55 is 12% of the sliding distance of the driving slide 65, so that the pressurized hydraulic cylinder 58 at this position is automatically located at 12% of the XY line, which is point D. Compared to Embodiment 3, this embodiment has a more compact layout. It does not require adjusting the position of the slide groove 521 by adjusting the gear size. The three sets of slide grooves 521 can be distributed at equal intervals, making the processing relatively simple. At the same time, with the setting of this embodiment, the helical spacing of the helical guide groove on the drive shaft 53 needs to be set to be larger, and the rotational resistance is smaller. Therefore, when the swing arm 52 swings, the drive slide 65 can drive the drive shaft 53 to rotate more easily. At the same time, when the position of the top plate 61 is adjusted, the restriction is also smaller due to the larger helical spacing on the drive shaft 53.

[0033] Example 4, based on the above examples, further includes a slide rail 41 and a servo motor 43. The slide rail 41 is fixedly mounted on the mounting platform 33, and a slider 42 is slidably connected to the upper surface of the slide rail 41. The mounting plate 45 is fixedly mounted on the upper surface of the slider 42. The servo motor 43 is fixedly mounted on the bottom of the mounting platform 33, and a lead screw 44 is fixedly mounted on the output end of the servo motor 43. A transmission screw sleeve is provided at the bottom of the mounting plate 45, and the transmission screw sleeve is threadedly connected to the lead screw 44.

[0034] Initially, servo motor 43 runs, driving lead screw 44 to rotate. Lead screw 44 moves mounting plate 45 via transmission screw sleeve. Mounting plate 45 drives slider 42 to slide along slide rail 41. When laser range sensor 46 detects its distance from the inner wall of right-angle storage slot 31, and when laser range sensor 46 moves to the contact point between the insole and right-angle storage slot 31 (Y point), the laser is blocked by the insole, and the detection distance decreases. The PLC built into the insulation box 1 receives the detection signal from laser range sensor 46 and controls servo motor 43 to stop running by cutting off power via PWM signal. The control is simple.

[0035] Example 5, based on the above examples, further includes: a support shaft 51 rotatably mounted on the upper surface of the mounting plate 45; a driven wheel 511 fixedly mounted at the bottom end of the support shaft 51; a servo motor 47 fixedly mounted on the upper surface of the mounting plate 45; a drive wheel 48 fixedly mounted at the output end of the servo motor 47; the drive wheel 48 meshing with the driven wheel 511; a rocker arm 52 sleeved on the top end of the support shaft 51; a threaded mounting hole 512 opened at the top end of the rocker arm 52; and a mounting bolt 522 threadedly connected to the outer side of the rocker arm 52, with the mounting bolt 522 threadedly connected in the threaded mounting hole 512.

[0036] Furthermore, a guide post 62 is provided on the side of the top plate 61 away from the mounting platform 33, and the sliding plate 63 is sleeved on the guide post 62.

[0037] After the Y-point positioning is completed, the second servo motor 47 is powered on and runs. The second servo motor 47 drives the drive wheel 48 to rotate. The drive wheel 48 drives the support shaft 51 to rotate through the driven wheel 511. The support shaft 51 drives the swing arm 52 to swing. When the second laser range sensor 64 moves to the X-point, the PLC built into the insulation box 1 receives the detection signal from the second laser range sensor 64 and controls the second servo motor 47 to stop running by cutting off the power through the PWM signal. The control is simple.

[0038] Example 6, based on the above examples, further includes a first baffle 32 on the side of the right-angle storage slot 31, and a second baffle 66 on the side of the top plate 61 near the mounting platform 33. The thickness of both the first baffle 32 and the second baffle 66 is less than the thickness of the insole. The laser point of the first laser rangefinder 46 moves along the outer edge of the first baffle 32, and the laser point of the second laser rangefinder 64 moves along the outer edge of the second baffle 66.

[0039] By setting the first stop bar 32 and the second stop bar 66, the Y point and the X point are on the edge lines of the first stop bar 32 and the second stop bar 66. The midpoint of the laser ranging is also located on the edge line, with half of it located on the first stop bar 32 and the second stop bar 66 and the other half located on the inner wall of the right-angle storage slot 31. The laser point located in the right-angle storage slot 31 is not large, so it is not easy to be blocked in advance, resulting in a smaller error. Therefore, the Y point and the X point can be located more accurately, improving the measurement accuracy.

[0040] Example 7, based on the above examples, further includes a door 11 on the top of the insulated box 1, and glass windows on both the front and back of the insulated box 1. The top door 11 facilitates the placement of shoe insoles, and the glass windows facilitate the observation of the interior of the insulated box 1.
