Description

Technical Field

[0001] The utility model relates to the field of mechanical die production, in particular to a positioning device for strip feeding. Background Art

[0002] At present, in the die industry, most strip feeding adopts the positioning form of pilot pins. The pilot pins are driven by air cylinders to expand and contract. That is, during positioning, the air cylinder drives the pilot pin to extend into the pre-punched holes of the strip, and then another air cylinder is used to shift to complete the material pulling action, making the strip move. After the material pulling is in place, the air cylinder driving the positioning pin returns, and the pilot pin withdraws from the positioning hole of the strip, and this material pulling is repeated. However, in actual production, the structure of the air cylinder and the stability of its movement are insufficient, resulting in floating of the pilot pin when it extends, and sometimes the strip will be warped to a certain extent. In this case, there is a risk that the pilot pin cannot penetrate into the positioning hole of the strip, resulting in inaccurate positioning, affecting the strip positioning and production quality. Therefore, designing a positioning device with stable and accurate positioning has become an issue of concern in the industry. The applicant has developed and innovated a strip feeding positioner through research and development, which is the application of this case. Summary of the Invention

[0003] The purpose of the utility model is to provide a strip feeding positioner with stable and accurate extension of the positioning pin feet, improving the positioning accuracy and stability of the strip.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The strip feeding positioner has:

[0006] A support structure, which includes a bottom plate and two guide plates installed on the bottom plate and spaced apart to form a feeding chute for guiding the movement of the strip; a guide post is erected on one of the guide plates;

[0007] A positioning member, which is sleeved on the guide post, and an elastic member is provided between the positioning member and the corresponding guide plate to support the positioning member, and the elastic member jacks up the positioning member to a certain height; the positioning member is provided with a downwardly protruding positioning pin foot, and the strip is positioned for feeding by inserting the positioning pin foot into a preset hole on the strip;

[0008] A control member, which is connected to the guide post through a pin shaft, enabling the control member to rotate between a first position and a second position. The control member rotates above the positioning member and uses its eccentric outer contour surface to press against the positioning member, causing the positioning member to move downward; when the control member rotates to the first position, the control member drives the positioning member to move downward, so that the positioning pin foot inserts into the hole on the strip; when the control member rotates to the second position, the control member releases the positioning member, and the positioning member drives the positioning pin foot to withdraw from the hole on the strip under the support of the elastic member.

[0009] Further, in the above solution, the positioning member has two spaced-apart positioning insertion plates, making the positioning member in the shape of a cover, and the spacing distance between the two positioning insertion plates matches the size of the guide plate in the same direction; when the positioning member moves downward, it is limited by the corresponding side edges of the guide plate by the two positioning insertion plates respectively, so that the positioning pins are correctly inserted into the holes on the tape.

[0010] Further, in the above solution, there are multiple positioning pins arranged in a row, and the orthographic projections of all the positioning pins fall on the bottom plate, and positioning holes are provided at the corresponding positions on the bottom plate, so that the positioning pins are sequentially inserted into the holes on the tape and the positioning holes on the bottom plate; both the holes on the tape and the positioning holes are rectangular holes, and the cross-sectional shape and size of the positioning pins at least match the holes on the tape.

[0011] Further, in the above solution, there are two guide posts arranged in parallel, and the control member is embedded between the two guide posts and is connected through a pin shaft passing through.

[0012] By adopting the above technical means, in the present utility model, the control member rotates on the upper side of the positioning member and uses the eccentric outer contour surface to press against the positioning member, so that the positioning member moves downward, achieving that the positioning pins on the positioning member are inserted into the preset holes on the tape to position the tape feeding. The control member is in hard contact with the positioning member, reducing the influence of external factors, such as not being affected by the telescopic floating of the air cylinder, making the positioning pins extend stably and in place, and also avoiding the risk that the positioning pins cannot be inserted into the holes due to the warping of the tape, improving the positioning accuracy and stability of the tape, facilitating subsequent production and processing, and ensuring the production quality.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] Referring to Figure 1 , 2 , Figures 3 and 4 show schematic diagrams of the preferred embodiments of the present utility model. The present utility model relates to a strip feeding positioner, which has a support structure 1, a positioning member 3 and a control member 4.

[0020] The support structure 1 can be installed on the corresponding material pulling equipment to cooperate with the strip feeding production. The support structure 1 includes a bottom plate 12 and two guide plates 13 installed on the bottom plate and spaced apart to form a feeding chute 11. In this embodiment, the two guide plates 13 are juxtaposed and stacked on the bottom plate 12 and extend parallel to each other to obtain a linear long feeding chute 11 to meet the passage of the strip. Preferably, the two guide plates 13 are vertically and crosswise arranged with the bottom plate 12, which is beneficial for manufacturing and installation. The feeding chute 11 guides the movement of the strip 2 to ensure that the strip 2 moves according to the set requirements. In this embodiment, a vertical guide post 14 is provided on the upper side of one of the guide plates 13. The positioning member 3 is sleeved on the guide post 14 and can move up and down, and an elastic member 5 is provided to support between the positioning member 3 and the corresponding guide plate 13. The elastic member 5 jacks up the positioning member 3 to a certain height. The positioning member is provided with a downwardly protruding positioning pin 31, and the strip feeding is positioned by inserting the positioning pin 31 into a preset hole 21 on the strip 2. The hole 21 is pre-opened on the strip 2 as needed. The control member 4 is connected to the guide post 14 through a pin shaft 6, so that the control member 4 can rotate between a first position and a second position. The control member 4 rotates above the positioning member 3 and uses the eccentric outer contour surface to press against the positioning member 3, so that the positioning member 3 moves downward and can overcome the elastic force of the elastic member 5. As Figure 1 shown, when the control member 4 rotates to the first position, the control member 4 drives the positioning member 3 to move downward, so that the positioning pin 31 is inserted into the hole 21 on the strip 2 for positioning connection. As Figure 3 , 4 shown, when the control member 4 rotates to the second position, the control member 4 releases the positioning member 3, so that the positioning member 3 drives the positioning pin 31 to withdraw from the hole 21 on the strip 2 under the support of the elastic member 5 to withdraw from the positioning for pulling the strip forward.

[0021] In this embodiment, the positioning member 3 is a square block, and positioning insertion plates 32 spaced from each other are respectively provided on opposite sides of the positioning member 3, making the positioning member 3 in the shape of a cover, and the spacing distance between the two positioning insertion plates 32 matches the dimension of the guide plate 13 in the same direction; when the positioning member 3 moves downward, it is limited by the corresponding sides of the guide plate 13 through the two positioning insertion plates 32 respectively, playing a role in guiding and correcting, so that the positioning pin 31 is accurately inserted into the belt holes 21 on the tape 2 and is not easily loosened, improving the accuracy and stability of the positioning connection.

[0022] There are multiple positioning pins 31 in this embodiment arranged in a row. Figure 1 、 2 As shown in FIGS. 3 and 4, there are three positioning pins 31, which vertically protrude downward on the corresponding sides of the positioning member 3. The orthographic projections of all the positioning pins 31 fall on the bottom plate 12, and positioning holes 121 are provided at corresponding positions on the bottom plate 12, allowing the positioning pins 31 to be sequentially inserted into the belt holes 21 on the tape 2 and the positioning holes 121 on the bottom plate 12. The positioning holes 121 further lock the insertion ends of the positioning pins 31, adding a positioning structure and making the positioning pins 31 not easily loosened. In this embodiment, both the belt holes 21 and the positioning holes 121 are rectangular holes, and it is further preferably that the sizes of the belt holes 21 and the positioning holes 121 are the same. The cross-sectional shape and size of the positioning pins 31 at least match the belt holes 21, and the directivity of the square is utilized to increase the positioning accuracy.

[0023] Figure 1 、 2 As shown in FIGS. 3 and 4, in this embodiment, there are two guide posts 14 arranged in parallel, and the control member 4 is embedded between the two guide posts and is connected through a pin shaft 6. The control member 4 is preferably a square block, restricted between the two guide posts, with stable rotation, which is conducive to the stable rotation of the control member 4 between the first position and the second position. Thus, the eccentric outer contour surface of the control member 4 can be used to press against the positioning member 3 to realize the effective movement of the positioning member 3. In this embodiment, the control member 4 acts on the positioning member 3 by switching between two adjacent side surfaces, and the eccentricity of the relative distance between the two adjacent side surfaces is used as the rotation reference to control the relative spatial position of the positioning member 3, so as to drive the positioning member 3 to move downward by the control member 4, insert the positioning pins 31 into the belt holes 21 on the tape 2 for positioning connection, and the side surface of the control member 4 presses, having a good pressure maintaining effect, making the positioning pins 31 not easily loosen and withdraw after being inserted into the belt holes 21 on the tape 2.

[0024] The utility model rotates the control part on the upper side of the positioning part and uses the eccentric outer contour surface to press against the positioning part, so that the positioning part moves downward, and the positioning pins on the positioning part are inserted into the preset tape holes on the tape to position the tape feeding. The control part is in hard contact with the positioning part, reducing the influence of external factors, such as not being affected by the telescopic floating of the cylinder, making the positioning pins extend stably and in place, and also avoiding the risk that the positioning pins cannot be inserted into the tape holes due to the warping of the tape, improving the positioning accuracy and stability of the tape, facilitating subsequent production and processing, and ensuring the production quality.

[0025] Certainly, the above detailed description of the present utility model in combination with the embodiments is only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it. Therefore, all equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
