TECHNICAL FIELD

[0001] The utility model relates to a shoe tree plane guide positioning mechanism. BACKGROUND

[0002] A shoe tree is a model used for making shoes, and through the shoe tree, the shape and structure of the shoes can be maintained during the making process, ensuring that the shoes maintain the correct shape during the production process and provide comfortable fit in the final form.

[0003] As disclosed in the Chinese utility model patent file with the publication number "CN207444402U", a through-hole structure injection shoe tree is disclosed, which is provided with two groups of positioning holes 2 on the shoe tree body. Figures 2 to 5 The positions of the positioning holes 2 can be clearly seen. These two groups of positioning holes are structures that must be processed during the manufacturing of the shoe tree, and the function of the positioning holes is to enable the mechanical arm to be fixed with the shoe tree body, realizing the automatic operation of the movement of the shoe tree body. This is not only for the convenience of processing the shoe tree, but also for the need to use the positioning holes during the process of using the shoe tree to produce shoes.

[0004] In order to process the two groups of positioning holes, the upper end of the shoe tree needs to be kept horizontal, and the orientation of the shoe tree needs to be along the established direction, so that the shoe tree can be positioned as a reference and the two groups of positioning holes can be processed. Therefore, when designing a shoe tree plane guide positioning mechanism, the most important technical problem to be solved is how to "ensure that the upper end of the shoe tree is kept horizontal and the orientation of the shoe tree is placed in the correct direction". UTILITY MODEL CONTENT

Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0027] As Figures 1 to 6 The shoe tree a plane guide positioning mechanism shown in the figure, including rack, shoe tree fixed guide plate 1, shoe tree movable guide plate 2, shoe tree fixed guide plate 1, shoe tree movable guide plate 2 are opposite respectively, shoe tree fixed guide plate 1 is fixed on the rack, the one side of shoe tree fixed guide plate 1 towards shoe tree movable guide plate 2 is equipped with left longitudinal center positioning groove 1a, left longitudinal center positioning groove 1a is located at the end towards shoe tree movable guide plate 2 and is open, the one side of shoe tree movable guide plate 2 towards shoe tree fixed guide plate 1 is equipped with right longitudinal center positioning groove 2a, right longitudinal center positioning groove 2a is located at the end towards shoe tree fixed guide plate 1 and is open, shoe tree movable guide plate 2 is linked with linear motion mechanism, linear motion mechanism can drive shoe tree movable guide plate 2 reciprocating movement towards shoe tree fixed guide plate 1.

[0028] The left longitudinal center positioning groove 1a and the right longitudinal center positioning groove 2a are parallel to each other and located on the same straight track. This ensures that the shoe tree a can move along a stable and straight path during insertion, avoiding deviation or tilting of the shoe tree a during insertion, thereby improving the accuracy of the guide and the positioning accuracy.

[0029] The upper end surface of the shoe tree fixed guide plate 1 is the left positioning reference plane 1b, and the upper end surface of the shoe tree movable guide plate 2 is the right positioning reference plane 2b. The left positioning reference plane 1b and the right positioning reference plane 2b are parallel to each other and located on the same horizontal plane. The left positioning reference plane 1b and the right positioning reference plane 2b are located on the same horizontal plane and are parallel to each other, which ensures that the upper end surface of the shoe tree a (mainly because the positioning reference planes a2 on both sides of the guide positioning block a1 are parallel to the upper end surface of the shoe tree a) is accurately positioned in the horizontal direction, avoiding positioning errors caused by the height difference between the two guide plates, and further improving the positioning accuracy of the shoe tree a.

[0030] The linear motion mechanism includes a lifting block 3 fixed to the shoe tree movable guide plate 2 below by a screw, the lifting block 3 is linked with a sliding block 4, the sliding block 4 is slidingly fitted with a sliding rail 5, the sliding rail 5 is fixed to the rack and parallel to the right longitudinal center positioning groove 2a, a transmission block 6 is fixed below the shoe tree movable guide plate 2, the transmission block 6 is linked with a gas cylinder 7, the body of the gas cylinder 7 is fixed to the rack, and the gas cylinder 7 can drive the shoe tree movable guide plate 2 to reciprocate along the axis of the sliding rail 5 through the transmission block 6. After the shoe tree a is inserted into the shoe tree fixed guide plate 1 and the shoe tree movable guide plate 2 through the two groups of guide positioning blocks a1 respectively, the gas cylinder 7 drives the shoe tree movable guide plate 2 to move along the axis of the sliding rail 5 through the transmission block 6. Since the sliding rail 5 is parallel to the right longitudinal center positioning groove 2a, the shoe tree movable guide plate 2 maintains a stable direction during movement until it tightly clamps the shoe tree a with the shoe tree fixed guide plate 1. After the shoe tree a is stably clamped, subsequent processing operations can be performed. After processing is completed, the gas cylinder 7 drives the shoe tree movable guide plate 2 to move in the opposite direction along the sliding rail 5, releasing the shoe tree a.

The heel limiting block 10 and the toe limiting block 11 are respectively installed by screws, so that the heel limiting block 10 and the toe limiting block 11 can be conveniently replaced or the installation positions of the heel limiting block 10 and the toe limiting block 11 can be changed, thereby adapting to different specifications and types of shoe trees a.

[0033] It should be noted that the shoe tree a using the positioning mechanism of the embodiment is provided with two groups of guide limiting blocks a1, one group of guide limiting blocks a1 is located near the toe part, and the other group of guide limiting blocks a1 is located at the heel, and each group of guide limiting blocks a1 is respectively provided with symmetric positioning reference planes a2, which are parallel to the upper end surface of the shoe tree a, and the purpose is to replace the upper end surface of the shoe tree a and the two groups of shoe tree a guide plates for guiding and positioning. When the shoe tree a is placed on the positioning mechanism of the embodiment, the upper end surface of the shoe tree a can be kept in a horizontal plane, facilitating the processing of the positioning hole.

[0034] The specific operation method of the embodiment is as follows: the linear motion mechanism drives the shoe tree movable guide plate 2 to move to an initial position, so that the distance between the shoe tree fixed guide plate 1 and the shoe tree movable guide plate 2 is large enough to accommodate the insertion of a shoe tree a. The tread surface of the shoe tree a is directed towards the two shoe tree a guide plates, and the two groups of guide limiting blocks a1 are respectively inserted into the left and right longitudinal center positioning grooves 1a and 2a, so as to ensure that the placement direction of the shoe tree a is correct and unique. Further, the positioning reference planes a2 on both sides of the two groups of guide limiting blocks a1 can be respectively contacted with the planes of the shoe tree fixed guide plate 1 and the shoe tree movable guide plate 2 by manually pressing the shoe tree a, so as to realize the positioning of the upper end surface of the shoe tree a, ensure that the upper end surface of the shoe tree a is kept in a horizontal plane, accurately perform the reference positioning, and promote the accurate positioning of the position and direction of the processed positioning hole. Once the shoe tree a is correctly guided and positioned, the linear motion mechanism is started to drive the shoe tree movable guide plate 2 to move to the left until the heel limiting block 10 contacts the heel of the shoe tree a and the toe limiting block 11 contacts the toe of the shoe tree a, so that the shoe tree a is tightly clamped by mutual cooperation. At this time, the position and direction of the shoe tree a are firmly locked. The linear motion mechanism drives the shoe tree movable guide plate 2 to move, which can adapt to different specifications and types of shoe trees a, and expand the adaptation range of the plane guiding and positioning mechanism of the shoe tree a.
