Description

Technical Field

[0001] This utility model relates to the field of shoe sole processing technology, specifically to a shoe sole positioning device. Background Technology

[0002] Sole positioning is crucial for establishing a spatial benchmark in shoe manufacturing, ensuring the coordinated achievement of geometric accuracy and functional reliability. As a key component for load-bearing and motion interaction within the shoe, the sole's spatial orientation directly determines its assembly coordination with components such as the upper and last. Deviations in its accuracy can lead to multi-dimensional performance degradation. Positioning errors can cause mismatches at the joint boundaries between the sole and upper, resulting in stress distribution deviating from design expectations, accelerated localized material fatigue, and reduced shoe lifespan. Positioning constraints on the sole's degrees of freedom during manufacturing ensure consistency between its geometric parameters and the design model, providing repeatable spatial references for each process. This allows for meeting the shoe's mechanical performance requirements while maintaining the stability and efficiency of the production process.

[0003] According to the authorization announcement number (CN220308564U), the positioning fixture for sports shoe production has a main body with synchronous lifting devices on both sides. The upper end of the groove is equipped with a sole clamping device for positioning and fixing the insole, enabling the positioning and fixing of the insole during sports shoe processing. In actual operation, the handle is manually rotated to drive the lifting frame to complete the lifting action, and then the displacement of the lifting frame drives the clamping plate to open and close. The greater the descent of the lifting frame, the more significant the clamping force generated by the clamping plate, thereby achieving the positioning operation of sports shoe soles of different sizes.

[0004] The structure disclosed in this patent has defects in practical applications, specifically as follows: During operation, the sole is placed between two clamping plates, and the two clamping plates are driven to move relative to each other to clamp the sole. However, for soles with elastic characteristics, when the clamping force is increased to ensure positioning stability, the sole is prone to bending deformation due to the force on both sides, especially in the transition area between the edge and the middle of the sole, which may cause irreversible stress damage. On the other hand, if the clamping force is reduced to avoid the risk of deformation, it is difficult to provide sufficient restraint, and the sole is prone to displacement due to external disturbances during processing, affecting positioning accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide a shoe sole positioning device, which addresses the problems in the prior art where excessive clamping force when two clamping plates clamp an elastic shoe sole from both sides can easily lead to bending deformation or irreversible stress damage to the shoe sole, while insufficient clamping force can result in unstable positioning. This device can improve the positioning effect of the shoe sole while avoiding deformation of the shoe sole due to positioning force.

[0006] This utility model is achieved through the following technical solution:

[0008] Furthermore, in this utility model, a first motor is installed on the aforementioned load-bearing suspension, and the output end of the first motor is connected to a first drive shaft; the first drive shaft passes through the first slider, and the first drive shaft and the first slider are connected by a thread, and the first drive shaft extends along the direction of the first guide rail.

[0009] Furthermore, in this utility model, the aforementioned supporting component includes: a transmission connecting plate connected to a first slider; a supporting bracket connected to the transmission connecting plate; a second motor mounted on the supporting bracket, the output end of which is connected to a second transmission shaft; and a second transmission shaft passing through the transmission connecting plate and engaging with a positioning component in a transmission manner. The positioning component is capable of moving up and down along the extension direction of the second transmission shaft, thereby positioning the shoe sole onto the positioning base plate from the top.

[0010] Furthermore, in this utility model, the aforementioned support bracket has a guide groove along its extension direction; the positioning component includes a lifting conductor, a transmission link, a positioning head, and a U-shaped positioning bracket. The lifting conductor has a threaded opening, which is threadedly engaged with the second transmission shaft; the transmission link passes through the guide groove, with one end connected to the lifting conductor and the other end connected to the positioning bracket; the opening of the positioning bracket faces the positioning base plate, and positioning heads are installed at both ends of the positioning bracket.

[0011] Furthermore, in this utility model, the positioning bracket is a hollow structure, and multiple first linkage balls are embedded in the positioning bracket along the extending direction; the positioning pressure head is slidably guided with the positioning bracket, and the positioning pressure head abuts against the first linkage balls; wherein, when the positioning pressure head contacts the uneven sole surface, the multiple first linkage balls are linked together to make the two positioning pressure heads adaptively adjust their positions.

[0012] Furthermore, in this utility model, the bottom end of the positioning pressure head is provided with a guide channel along the extending direction, and an adjusting slide is slidably mounted in the guide channel. The adjusting slide can be locked to a preset position in the guide channel. The bottom end of the adjusting slide is provided with a U-shaped linkage guide groove, and multiple second linkage balls are embedded in the linkage guide groove along the extending direction. Auxiliary pressure heads are slidably mounted at both ends of the linkage guide groove, and the auxiliary pressure heads abut against the second linkage balls. The two adjusting slides can be locked to a preset position in the guide channel, thereby adjusting the distance between the two adjusting slides to adapt to the positioning requirements of shoe soles of different lengths.

[0013] Furthermore, in this utility model, the above also includes a positioning pin; the side wall of the guide channel is provided with a plurality of adjustment locking holes along the extension direction; the adjustment slide is provided with a positioning locking hole, which can be aligned with a preset adjustment locking hole; the positioning pin can pass through the positioning locking hole and the preset adjustment locking hole, thereby locking the relative position of the adjustment slide.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] 1. In this application, the positioning component performs multi-point collaborative positioning on the sole from the top, so that the positioning force is evenly distributed on the top surface of the sole. This top pressure design completely replaces the traditional side clamping method, eliminating the bending deformation and irreversible stress damage of the sole caused by excessive clamping force at the source. The multi-point collaborative constraint provides stable constraint force, avoids displacement caused by external force disturbance during processing, and greatly improves positioning stability.

[0016] 2. In this application, the positioning component is adjusted to be directly above the sole by displacement in the first and second directions.

[0017] 3. In this application, the positioning pressure head and the auxiliary pressure head can adapt to the surface shape and thickness differences of the shoe sole. The multi-point collaborative positioning of the positioning pressure head, combined with the adaptive adjustment of the first linkage ball, can adapt to the processing requirements of shoe soles with different flatness and thickness gradients, completely replacing the traditional method of manually calibrating the pressure, and greatly improving the positioning adaptability and operational stability of the device.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0027] Example

[0028] Please refer to Figure 1 and Figure 2 This utility model provides a shoe sole positioning device. It includes a positioning platform 1, a positioning base plate 2, a support suspension 3, a first slider 5, a support assembly, and a positioning assembly. The positioning base plate 2 is slidably mounted on the positioning platform 1 and can be locked at a preset position in a first direction. The support suspension 3 is mounted on the positioning platform 1 and has a first guide rail 4. The first slider 5 is slidably embedded in the first guide rail 4 and can be locked at a preset position in a second direction. The support assembly is mounted on the first slider 5, and the positioning assembly is mounted on the support assembly, enabling the positioning assembly to position the shoe sole onto the positioning base plate 2 from the top.

[0029] During operation, the operator places the shoe sole in the processing area of ​​the positioning base plate 2 to ensure that the initial placement posture is stable. According to the shoe sole specifications, the operator adjusts the position of the positioning base plate 2 in the first direction and adjusts the first slider 5 to the preset position in the second direction, so that the positioning component moves synchronously to the corresponding position in the second direction, thereby making the positioning component accurately aligned with the optimal positioning position directly above the shoe sole.

[0030] The positioning component can perform multi-point collaborative positioning of the top of the sole, and by utilizing the balanced distribution of multi-point forces, it can prevent the sole from undergoing unexpected deformation during the positioning process due to its own elasticity. This positioning state can directly provide a benchmark for subsequent processing steps, including but not limited to the cutting of the sole edge, the fitting and positioning of the upper and sole, the processing and positioning of the sole functional structure (such as anti-slip patterns and ventilation holes), and the benchmark calibration of the heel assembly, thereby ensuring the dimensional accuracy and process stability of subsequent processing.

[0031] It should be noted that the first direction and the second direction are perpendicularly distributed in space. The position adjustment of the positioning base plate 2 along the first direction and the position adjustment of the first slider 5 along the second direction form an orthogonal adjustment system. The positioning component can achieve multi-dimensional position adjustment in the plane formed by the first direction and the second direction, thereby accurately adjusting to the optimal positioning position of the shoe sole.

[0032] Please refer to Figure 1 In some embodiments of this application, a first motor 8 is mounted on the load-bearing suspension 3, and the output end of the first motor 8 is connected to a first drive shaft 6. The first drive shaft 6 is arranged along the extension direction of the first guide rail 4 and passes through the first slider 5, and the first drive shaft 6 and the first slider 5 form a threaded engagement. One end of the first drive shaft 6 is connected to the output end of the first motor 8, and the other end extends to the end of the first guide rail 4 and is rotatably mounted via a bearing. When the first motor 8 drives the first drive shaft 6 to rotate, the threaded engagement between the first drive shaft 6 and the first slider 5 can drive the first slider 5 to adjust its position along a second direction.

[0033] Please refer to Figures 1 to 3In some embodiments of this application, the supporting component includes a transmission connecting plate 7, a supporting bracket 9, a second motor 17, and a second transmission shaft 18. The transmission connecting plate 7 is connected to the first slider 5, the supporting bracket 9 is connected to the transmission connecting plate 7, the second motor 17 is mounted on the top of the supporting bracket 9, and the output end of the second motor 17 is connected to the second transmission shaft 18 via a coupling. The second transmission shaft 18 extends vertically and passes through the transmission connecting plate 7. The supporting component achieves mechanical linkage with the first slider 5 through the transmission connecting plate 7. When the first slider 5 moves along the second direction, the supporting component moves synchronously. When it moves to a preset position, the second motor 17 drives the second transmission shaft 18 to rotate, driving the positioning component to move up and down along the axial direction of the second transmission shaft 18, thereby controlling the displacement stroke of the positioning component according to the specifications of the shoe sole, and achieving precise positioning of the top of the shoe sole.

[0034] Please refer to Figures 1 to 3 In some embodiments of this application, the support bracket 9 has a guide groove 10 along its vertical direction; the positioning assembly includes a lifting conductor 20, a transmission link, a positioning pressure head 12, and a positioning bracket 11 with a U-shaped structure. The lifting conductor 20 has a threaded through hole, and the two lifting conductors 20 are in transmission cooperation with the second transmission shaft 18; one end of the transmission link is connected to the lifting conductor 20, and the other end passes through the guide groove 10 and is connected to the positioning bracket 11.

[0035] The opening of the positioning bracket 11 faces the positioning base plate 2, and positioning pressure heads 12 are respectively installed on the two free ends of the positioning bracket 11. When the second motor 17 drives the second transmission shaft 18 to rotate, the rotational motion of the second transmission shaft 18 is converted into linear motion of the lifting conductor 20, driving the lifting conductor 20 to make linear displacement along the extension direction of the guide groove 10; the transmission link forms a sliding fit with the guide groove 10, constraining the motion trajectory of the lifting conductor 20, ensuring that the lifting conductor 20 can only make linear lifting and lowering motion along the extension direction of the guide groove 10, thereby driving the positioning bracket 11 and the positioning pressure head 12 to lift and lower synchronously.

[0036] The positioning heads 12 at the two free ends of the positioning bracket 11 correspond to the forefoot and heel of the shoe sole, respectively. The two rigid support areas are positioned synchronously. The structural rigidity of the forefoot and heel can be used to offset the asymmetric deformation caused by the difference in elastic modulus distribution of the shoe sole during the positioning process. This provides accurate spatial coordinate reference for subsequent processing steps to ensure processing accuracy and product consistency.

[0037] Please refer to Figure 4For example, the positioning bracket 11 adopts a hollow cavity structure, and multiple first linkage balls 22 arranged in a linear array are embedded inside the positioning bracket 11 along the extension direction. The multiple first linkage balls 22 maintain rolling contact to form a continuous transmission chain; the positioning pressure head 12 forms a sliding guide fit with the free end of the positioning bracket 11, and the inner end of the positioning pressure head 12 abuts against the first linkage balls 22.

[0038] When the positioning pressure head 12 contacts the sole surface, due to the ergonomic thickness gradient difference between the forefoot and heel, the contact height of the two positioning pressure heads 12 differs. Multiple first linkage balls 22 form an adaptive linkage adjustment mechanism. This adjustment mechanism automatically compensates for the height difference based on the characteristics of the sole, ensuring that the two positioning pressure heads 12 always maintain full contact with the sole surface. This ensures that the positioning pressure is evenly distributed in the forefoot metatarsal area and the heel calcaneal tuberosity area, effectively avoiding sole deformation or positioning inaccuracy caused by localized pressure concentration, and providing a stable and reliable positioning reference for subsequent processing.

[0039] Please refer to Figure 5 For example, the bottom end of the positioning pressure head 12 is provided with a guide channel 23, and an adjusting slide 24 is slidably mounted in the guide channel 23, and the adjusting slide 24 can be locked in a preset position in the guide channel 23; the bottom end of the adjusting slide 24 is provided with a U-shaped linkage guide groove 25, and a plurality of second linkage balls 26 are embedded in the linkage guide groove 25 along the extending direction. Auxiliary pressure heads 27 are slidably mounted at both ends of the linkage guide groove 25 (the auxiliary pressure heads 27 slide and guide the inner wall of the linkage guide groove 25), and the auxiliary pressure heads 27 roll and abut against the second linkage balls 26. By locking the two adjusting slides 24 in the preset positions of the guide channel 23, the distance between the two adjusting slides 24 can be adjusted to adapt to the positioning requirements of shoe soles of different lengths.

[0040] During the sole positioning operation, the two positioning pressure heads 12 are driven to move towards the sole, and the adjusting slides 24 at the bottom of the positioning pressure heads 12 are pressed down synchronously, so that the auxiliary pressure head 27 on the adjusting slide 24 contacts the sole surface. The above positioning structure enhances the positioning effect through multi-point synergy, specifically: First, the rolling cooperation between the auxiliary pressure head 27 and the second linkage ball 26 forms an adaptive adjustment mechanism. When the auxiliary pressure head 27 contacts the uneven sole surface, the multiple second linkage balls 26 redistribute the force through rolling displacement, ensuring that both auxiliary pressure heads 27 can maintain effective contact with the sole surface, thereby solving the problem of positioning instability caused by uneven sole surface; Second, the operator can adjust the relative position of the two adjusting slides 24 in the guide channel 23 according to the specific specifications of the sole, so that the auxiliary pressure head 27 is precisely aligned with the forefoot and heel of the sole. Through the precise positioning of these two key support points, the displacement and deformation of the sole during processing can be effectively suppressed, significantly improving the stability and reliability of sole positioning.

[0041] Please refer to Figure 5 The positioning structure of the adjusting slide 24 also includes a positioning pin 30; the side wall of the guide channel 23 is provided with a plurality of adjusting locking holes 29 along the extension direction, and the corresponding position of the adjusting slide 24 is provided with a positioning locking hole 28, which can be aligned with the preset adjusting locking hole 29 as the adjusting slide 24 slides; the positioning pin 30 can pass through the aligned positioning locking hole 28 and adjusting locking hole 29 to lock the relative position of the adjusting slide 24 in the guide channel 23.

[0042] When the position of the adjusting slide 24 needs to be adjusted, the operator first releases the locking state of the positioning pin 30 on the adjusting slide 24, drives the adjusting slide 24 to slide along the guide channel 23 to the preset position, so that the positioning locking hole 28 on the adjusting slide 24 is coaxially aligned with the corresponding adjusting locking hole 29 on the side wall of the guide channel 23; the positioning pin 30 is inserted into the through hole formed by the positioning locking hole 28 and the adjusting locking hole 29, and the positioning pin 30 is tightened with the thread of the locking hole, etc., to lock the position of the adjusting slide 24 in the guide channel 23. This ensures that the adjusting slide 24 can achieve multi-level position adjustment within the preset stroke of the guide channel 23, providing a quantifiable adjustment benchmark for the positioning needs of different specifications of shoe soles, while ensuring the structural rigidity and vibration resistance in the locked state, effectively avoiding displacement of the adjusting slide 24 due to vibration or external force during processing.

[0043] Please refer to Figure 1 and Figure 2In some embodiments of this application, second guide rails 15 are provided on opposite sides of the positioning platform 1, and second sliders 16 are correspondingly installed on both sides of the bottom end of the positioning base plate 2. The two second sliders 16 are slidably engaged with the second guide rails 15 respectively. A third motor 13 is installed on the positioning platform 1, and a third transmission shaft 14 is installed at the output end of the third motor 13. A transmission component is installed at the bottom end of the positioning base plate 2, and the third transmission shaft 14 passes through the transmission component and is threadedly engaged. The other end of the third transmission shaft 14 is rotatably mounted on the positioning platform 1 through a bearing, so that the third motor 13 controls the rotation of the third transmission shaft 14 to control the movement of the positioning base plate 2 in the first direction.

[0044] A second guide rail 15 is provided on each of the opposite sides of the positioning platform 1. A second slider 16 is installed on each of the two sides of the bottom end of the positioning base plate 2, and the second slider 16 slides into contact with the second guide rail 15. A third motor 13 is mounted on the positioning platform 1. The output shaft of the third motor 13 is connected to a third transmission shaft 14 via a coupling. The third transmission shaft 14 is rotatably supported on the positioning platform 1 via a bearing seat. A transmission slide 19 is installed at the bottom end of the positioning base plate 2, and the transmission slide 19 has a threaded through hole adapted to the third transmission shaft 14. When the third motor 13 drives the third transmission shaft 14 to rotate, it drives the positioning base plate 2 to make linear displacement along the axial direction of the second guide rail 15, thereby realizing the position adjustment of the positioning base plate 2 in the first direction.
