Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a lifting inner support feeding mechanism. Background Technology

[0002] In modern manufacturing and automation, material handling within confined spaces is a common technical challenge. For example, in the processes of clamping, supporting, and feeding, traditional internal support feeding mechanisms often struggle to meet diverse needs due to the varied shapes of the materials. This not only affects production efficiency but can also lead to inconsistent product quality.

[0003] Existing internal support feeding mechanisms have several shortcomings in terms of precision and stability. On the one hand, they are difficult to achieve rapid internal clamping and stable transport in confined spaces, leading to production interruptions and delays. On the other hand, the lack of an effective self-locking mechanism during retraction makes automated production lines prone to malfunctions, affecting the continuity and reliability of production. Furthermore, existing internal support feeding mechanisms are typically complex in structure and occupy a large amount of space, making them difficult to meet the requirements of modern production for equipment miniaturization and high efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a lifting and internal support feeding mechanism with a compact overall structure and small footprint. By incorporating a lifting drive module and a wedge-shaped internal support module, it enables rapid internal support clamping and stable transport of materials in confined spaces. Furthermore, it features self-locking during retraction, ensuring uninterrupted operation of automated production lines.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] Reference Figures 1 to 3 As shown, the lifting inner support feeding mechanism provided by this utility model ensures stable operation, precise clamping, large clamping force, high repeatability, and a self-locking function. It includes a cylinder body 1, a bracket 2 for mounting the cylinder body 1, at least one wedge-shaped inner support module 3 disposed within the cylinder body 1, at least one lifting drive module 4 for driving the cylinder body 1 to rise and fall relative to the bracket 2, and a self-locking module 5 disposed between the cylinder body 1 and the bracket 2. In a specific embodiment, please refer to... Figure 2 The wedge-shaped inner support module 3 is set to 3 units, and the lifting drive module 4 is set to 2 units.

[0031] During the descent of the cylinder 1 driven by the lifting drive module 4, the cylinder 1 is used to trigger the self-locking module 5 to lock and fix the cylinder 1; the wedge-shaped inner support module 3 includes a wedge-shaped drive block 31 disposed in the cylinder 1, an inner support drive cylinder 32 for driving the wedge-shaped drive block 31 to rise and fall, and a wedge-shaped push block 33 disposed on each of the two opposite outer sides of the wedge-shaped drive block 31; a telescopic hole is opened on the side of the cylinder 1 corresponding to each wedge-shaped push block 33; when the inner support drive cylinder 32 drives the wedge-shaped drive block 31 to move, the wedge-shaped push block 33 extends or retracts through the corresponding telescopic hole.

[0032] The cylinder body 1 has a first inner cavity for each lifting drive module 4; the first inner cavity is opened vertically and extends through the bottom of the cylinder body 1; the lifting drive module 4 includes a lifting drive cylinder 41 and a lifting elastic member 42 disposed between the lifting drive cylinder 41 and the top of the first inner cavity; the bottom end of the lifting drive cylinder 41 is fixed to the bracket 2, and the top end extends into the first inner cavity; when the lifting drive cylinder 41 is not ventilated, the lifting elastic member 42 extends to lift the cylinder body 1; when the lifting drive cylinder 41 is ventilated, the cylinder body 1 is driven to descend and compress the lifting elastic member 42.

[0033] Specifically, the lifting elastic element 42 is a spring. By setting the lifting elastic element 42, when the cylinder 1 descends, the lifting elastic element 42 is compressed, and the self-locking module 5 automatically locks and fixes the cylinder 1. When the self-locking module 5 releases the cylinder 1, the cylinder 1 can automatically rise under the elastic force of the lifting elastic element 42, so that the upper part of the cylinder 1 and the wedge-shaped push block 33 extend into the clamping hole of the material.

[0034] The lifting drive cylinder 41 includes a lifting piston rod extending into the first inner cavity and a lifting piston mounted on the lifting piston rod; the lifting elastic element 42 abuts against the top of the lifting piston and the first inner cavity and is sleeved on the lifting piston rod. Since the bottom end of the lifting drive cylinder 41 is fixed to the bracket 2, the lifting piston rod and the lifting piston do not move during the lifting and lowering process of the cylinder body 1; only the cylinder body 1 moves relative to the lifting piston rod and the lifting piston. When the lifting drive cylinder 41 is vented, that is, vented into the first inner cavity, the cylinder body 1 descends, thereby compressing the lifting elastic element 42.

[0035] A cylinder cover plate 43 is provided between the first inner cavity and the bottom of the cylinder body 1; during the rising process of the cylinder body 1, the lifting piston and the cylinder cover plate 43 limit the rising stroke of the cylinder body 1.

[0036] The wedge-shaped push block 33 is provided with a first guide slide rail; the two opposite outer sides of the wedge-shaped drive block 31 are respectively provided with first guide grooves that match the first guide slide rail. By setting the first guide slide rail and the first guide groove between the wedge-shaped push block 33 and the wedge-shaped drive block 31, the lifting and lowering movement of the wedge-shaped drive block 31 is precisely guided, so that the wedge-shaped push block 33 can be stably extended and retracted.

[0037] In another specific embodiment, the wedge-shaped drive block 31 is configured as a wedge-shaped structure that gradually shrinks from top to bottom. When the inner support drive cylinder 32 drives the wedge-shaped drive block 31 to rise, the wedge-shaped push block 33 can retract from the telescopic hole. When the inner support drive cylinder 32 drives the wedge-shaped drive block 31 to fall, the wedge-shaped push block 33 extends out from the telescopic hole and tightens in the clamping hole of the material, that is, it clamps the material from the clamping hole of the material.

[0038] The self-locking module 5 includes a slot 51 formed on one side of the bottom of the cylinder 1, a self-locking hook 52 matching the slot 51, a self-locking fixing seat 53 fixed to the bracket 2, and a self-locking elastic element disposed between the self-locking fixing seat 53 and the self-locking hook 52; the top of the self-locking hook 52 is provided with a ramp surface on the side near the cylinder 1. Specifically, the self-locking elastic element is a spring. In the self-locking module 5, by providing a ramp surface on the self-locking hook 52, during the descent of the cylinder 1, the bottom of the cylinder 1 abuts against the slidable compressible self-locking elastic element on the ramp surface, causing the self-locking hook 52 to retract so that the cylinder 1 can continue to descend; when the cylinder 1 descends to the position, the self-locking hook 52 pops out under the elastic action of the self-locking elastic element, and the self-locking hook 52 is limited to the slot 51, restricting the cylinder 1 from rising.

[0039] A lifting guide module 6 is provided at each end of the cylinder 1 between it and the bracket 2. In one specific embodiment, the lifting guide module 6 includes a slide rail and a slider, so that the cylinder 1 can operate with high precision and stability under the guiding and restraining effect of the lifting guide module 6. The bracket 2 has a U-shaped structure, and a lifting guide module 6 is provided on the inner wall of each U-shaped vertical end of the bracket 2.

[0040] The lifting and internal support feeding mechanism provided by this utility model works as follows:

[0041] 1) The self-locking hook 52 is opened by an external mechanism. At this time, the lifting drive cylinder 41 is not ventilated. The cylinder body 1 is lifted by the elastic force of the lifting elastic element 42, so that the upper part of the cylinder body 1 and the wedge-shaped push block 33 extend into the clamping hole of the material.

[0042] 2) Under the driving action of the inner support drive cylinder 32, the wedge drive block 31 descends, causing the wedge push block 33 to extend from the telescopic hole and tighten in the clamping hole of the material.

[0043] 3) Ventilate the lifting drive cylinder 41 to drive the cylinder body 1 to descend and compress the lifting elastic element 42;

[0044] 4) During the descent of cylinder 1, cylinder 1 abuts against self-locking hook 52, thereby locking and fixing cylinder 1 with self-locking module 5.

[0045] 5) The inner support drive cylinder 32 drives the wedge drive block 31 to rise, causing the wedge push block 33 to retract and return to its original position, releasing the material and completing the material transportation.
