Description

Technical Field

[0001] The utility model relates to the field of shoe machines, in particular to a shoe last which is convenient for accurate positioning. Background Art

[0002] During the process of shoe upper processing, it is generally necessary to position it through the shoe last, and then process it (such as gluing, polishing, etc.).

[0003] Existing shoe lasts, such as Chinese patent CN202322726470.3, mainly achieve positioning of the shoe last through the cooperation of sliders and fixing grooves. However, in actual automated processing, its design requirements need to reach 0.1 mm level or even higher; thereby realizing automated processing of multi-axis robots, but the use of sliders and fixing grooves only achieves positioning in the X-axis direction, so there is still an error in the Y-axis direction, affecting the consistency of automated processing.

[0004] Of course, there is also a method of setting up another blocking structure at another position of the shoe last to achieve positioning, but its structure is relatively complicated. Utility Model Content

[0005] The main purpose of the utility model is to propose a shoe last that is easy to accurately position, aiming to improve the structure of the shoe last, thereby achieving accurate positioning of the shoe last in the X-axis and Y-axis directions at a predetermined workstation, thereby ensuring the stability of automated processing.

[0006] In order to achieve the above purpose, the present invention proposes a shoe last that is convenient for accurate positioning, comprising a main body,

[0007] The main body includes a covering portion and a root portion extending downward from the covering portion.

[0008] The root portion is used to cooperate with the supporting seat;

[0009] The opposite sides of the outer wall of the root are provided with grooves extending along the Y-axis direction.

[0010] The groove is further provided with at least one limiting portion extending in the Z-axis direction or provided in the groove.

[0011] In the actual design, the width direction of the shoe last is the X axis, the length direction is the Y axis, and the height direction is the Z axis;

[0012] During the actual clamping process, the shoe last is placed on the supporting seat. What needs to be achieved through the clamping device is that the shoe last is stably fixed on the supporting seat and the positions of the two need to be accurately positioned to ensure the stability of the processing;

[0013] The clamping device (composed of two clamping jaws for clamping both sides of the root) is provided with a strip portion that cooperates with the groove, and a positioning portion that cooperates with the limiting portion. When the strip portion extends into the groove, the shoe last can be positioned in the X-axis and Z-axis directions. That is, this single structure can achieve the clamping and fixing of the shoe last. However, the shoe last also involves positioning in the Y-axis direction. Therefore, when the limiting portion and the positioning portion cooperate, the shoe last can be accurately positioned in the Y-axis direction.

[0014] Therefore, the automated processing of the multi-axis manipulator can be effectively guaranteed, and the positioning between the shoe last and the supporting seat is more stable (the clamping device is also provided with a positioning pin that cooperates with the supporting seat).

[0031] like Figures 1 to 5 As shown, a shoe last that facilitates precise positioning includes a main body 1,

[0032] The main body 1 includes a covering portion 11 and a root portion 12 extending downward from the covering portion 11.

[0033] The root portion 12 is used to cooperate with the supporting seat;

[0034] The outer wall of the root 12 is provided with grooves 21 extending along the Y-axis direction on two opposite sides.

[0035] The groove 21 is further provided with at least one limiting portion 22 extending in the Z-axis direction or provided in the groove.

[0036] In the actual design, the width direction of the shoe last is the X axis, the length direction is the Y axis, and the height direction is the Z axis;

[0037] During the actual clamping process, the shoe last is placed on the supporting seat. What needs to be achieved through the clamping device is that the shoe last is stably fixed on the supporting seat and the positions of the two need to be accurately positioned to ensure the stability of the processing;

[0038] The clamping device (composed of two clamping jaws for clamping both sides of the root 12) is provided with a strip portion that cooperates with the groove 21, and a positioning portion that cooperates with the limiting portion 22. When the strip portion extends into the groove 21, the shoe last can be positioned in the X-axis and Z-axis directions. That is, this single structure can achieve the clamping and fixing of the shoe last. However, the shoe last also involves positioning in the Y-axis direction. Therefore, when the limiting portion 22 and the positioning portion cooperate, the shoe last can be accurately positioned in the Y-axis direction.

[0039] Therefore, the automated processing of the multi-axis manipulator can be effectively guaranteed, and the positioning between the shoe last and the supporting seat is more stable. The clamping device is also provided with a positioning pin that cooperates with the supporting seat.

[0040] In the embodiment of the present invention, the limiting portion 22 is a protrusion or a limiting groove, which can be set according to different scenarios and needs.

[0041] In the embodiment of the present invention, the limiting portion 22 extends from the upper side and / or the lower side of the groove 21 , wherein the limiting portion 22 can be symmetrically arranged on both sides of the groove 21 , or only on one side.

[0042] In the embodiment of the present invention, when the limiting portion 22 is a limiting groove, the inner end surface of the limiting portion 22 is in an arc shape.

[0043] In the embodiment of the present invention, the limiting groove is configured to gradually reduce in diameter from the outside to the inside. The setting of the limiting portion 22 can achieve preliminary guidance and simultaneously achieve accurate position correction of the shoe last at the bottom end of the limiting groove.

[0044] In the embodiment of the present invention, the inner end wall of the groove 21 is in an arc shape, which not only facilitates clamping but also achieves guiding and positioning.

[0045] Specifically, the main body 1 further includes a raised seat 3 installed on the root portion 12 , and the raised seat 3 is provided with the groove 21 and the limiting portion 22 .

[0046] Specifically, a hollow air-avoiding groove 4 is provided in the middle of the raising seat 3 , thereby facilitating the installation and fixation between the raising seat 3 and the shoe last, and also reducing the weight thereof.

[0047] That is, it can be understood that the raised seat and the root are an integrated structure, or the root can be produced as a separate structure.

[0048] Specifically, a first socket 51 is provided at the bottom of the raising seat 3, a plug post 5 is provided on the upper wall of the bottom, and a second socket 52 is provided at the root 12 to match the plug post. It can be customized according to actual needs. Of course, the existing shoe last can be retained to avoid waste, and the raising seat 3 can be directly added.

[0049] Specifically, the root 12 is provided with a screw hole 61, and the upper wall of the raised seat 3 is provided with a screw through hole 62 that matches the screw hole. A screw passes through the screw through hole and is screwed into the screw hole, thereby facilitating the installation between the root 12 and the raised seat 3.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
