Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, specifically relating to a leg riveting tool. Background Technology

[0002] A type of support structure such as Figure 4 As shown, it mainly includes a leg upright plate and support plates and bushings at both ends of the leg upright plate. The leg upright plate and support plates are vertically connected, and there is an offset between them in the width direction. Since the leg upright plate has a certain length, it is generally laid flat during assembly, i.e., horizontal assembly is used. After assembly, it is then lifted to the next process. In relevant existing technologies, conventional riveting fixtures serve as supporting and positioning structures. When lifted from one end after assembly, the leg structure is prone to collision with the fixture, causing damage. Furthermore, horizontal lifting increases the difficulty of the operation, thus often requiring manual operation, affecting efficiency and the dimensional accuracy of the leg structure. Utility Model Content

[0003] This invention aims to solve at least one of the aforementioned technical problems in the prior art. To this end, this invention provides a leg riveting fixture that can solve the problem of interference during component lifting, thereby improving work efficiency.

[0004] The outrigger riveting fixture according to an embodiment of the present utility model includes:

[0005] Base frame;

[0006] Two uprights are spaced apart on the base frame along a first direction, forming a receiving space between the two uprights to accommodate a support plate. Positioning pins are provided on the opposing sides of the two uprights, which can be inserted into preset holes on both sides of the support plate to position the support plate. The spacing between the two uprights can be adjusted along the first direction. A first support platform protrudes from the same side of the two uprights along a second direction, which intersects with the first direction.

[0007] The second support platform is disposed on the base frame, and a V-shaped positioning groove is provided at the upper end of the second support platform;

[0008] The column, the first support platform, and the second support platform are arranged sequentially along the second direction. The column is used to position the support plate, the first support platform and the second support platform jointly support the leg plate, and the V-shaped positioning groove is used to position the bushing. The two columns can move away from each other until the leg plate enters the receiving space.

[0009] The leg riveting fixture according to the embodiment of this utility model has at least the following beneficial effects:

[0010] In this embodiment, the outrigger riveting fixture uses two locating pins on the uprights to insert into pre-drilled holes on the support plate. This allows the support plate to be suspended and positioned between the two uprights, enabling it to rotate around the locating pins. Then, a first support platform and a second support platform support both ends of the outrigger upright. Since the first support platform is mounted on the uprights, it maintains the docking and positioning of the outrigger upright and the support plate. Simultaneously, the V-shaped locating groove of the second support platform positions the bushing, ensuring the dimensional accuracy of each assembled outrigger. After assembly, when lifting the outrigger structure from the bushing, the support plate can rotate upwards around the locating pin. By adjusting the distance between the two uprights, the uprights avoid interfering with the outrigger upright, which is offset from the support plate in the first direction. When the outrigger structure is lifted vertically, the locating pins can be removed, or the distance between the two uprights can be further adjusted to separate the locating pins from the support plate, allowing the outrigger structure to be smoothly lifted away.

[0011] In summary, the leg riveting fixture of this embodiment solves the interference problem when the components and the fixture rotate relative to each other due to the offset between different components. The positioning position can be kept consistent every time, which is beneficial to improving production efficiency and production quality.

[0012] According to some embodiments of this utility model, the positioning pin is inserted into the column and can be pulled outward.

The third support platform is fixedly mounted on the base frame and located between the first support platform and the second support platform. The third support platform is provided with a support inclined surface and a first vertical reference surface. The support inclined surface and the first vertical reference surface are distributed along the first direction. The support inclined surface is used to support the outrigger upright plate and guide the outrigger upright plate toward the direction of the first vertical reference surface.

[0014] According to some embodiments of the present invention, the second support platform is provided with a second vertical reference surface on one side of the V-shaped positioning groove, and along the second direction, the second vertical reference surface is flush with the first vertical reference surface.

[0015] According to some embodiments of this utility model, the two columns include a first column and a second column. Along the first direction, the first column and the first vertical reference plane are located on the same side. The first column is fixedly connected to the base frame, and the second column moves along the first direction.

[0031] Reference Figures 1 to 4 An embodiment of this utility model provides a leg riveting fixture, comprising:

[0032] The base frame 100 is mainly used to provide a supporting foundation;

[0033] Two uprights 200 are spaced apart along a first direction on the upper surface of the base frame 100, forming a space between them to accommodate a support plate 501. Positioning pins 204 are provided on the opposing sides of the two uprights 200, which can be inserted into pre-drilled holes on both sides of the support plate 501 to position it, thus suspending the support plate 501 within the space. The spacing between the two uprights 200 along the first direction can be adjusted, thereby changing the size of the space in that direction, for example, increasing or decreasing it. A first support platform protrudes from the same side of the two uprights along a second direction, perpendicular to the first direction.

[0034] The second support platform 300 is set on the upper surface of the base frame 100, and the upper end of the second support platform 300 is provided with a V-shaped positioning groove.

[0035] The column 200, the first support platform, and the second support platform 300 are arranged sequentially along a second direction, so that the accommodating space is distributed along the second direction with the first support platform and the second support platform 300. The column 200 is used to position the support plate 501, the first support platform and the second support platform 300 jointly support the leg plate 500, and the V-shaped positioning groove is used to position the bushing 502. The two columns 200 can be spaced apart from each other, increasing the size of the accommodating space, so that the leg plate 500 can enter the accommodating space.

[0036] In this embodiment, the outrigger riveting fixture uses positioning pins 204 of two columns 200 inserted into preset holes on the support plate 501. This allows the support plate 501 to be suspended and positioned between the two columns 200, and enables the support plate 501 to rotate around the positioning pins 204. Then, the first support platform and the second support platform 300 support both ends of the outrigger plate 500. Since the first support platform is located on the columns 200, it maintains the docking and positioning of the outrigger plate 500 and the support plate 501. Simultaneously, the V-shaped positioning groove of the second support platform 300 positions the bushing 502, ensuring the dimensional accuracy of the outrigger in each assembly. After assembly, when the outrigger structure is lifted from bushing 502, the support plate 501 can rotate upward around the positioning pin 204. By adjusting the distance between the two columns 200, the columns 200 can avoid the outrigger plate 500, which is offset from the support plate 501 in the first direction, thus avoiding interference. When the outrigger structure is lifted to a vertical position, the positioning pin 204 can be removed, or the distance between the two columns 200 can be further adjusted to separate the positioning pin 204 from the support plate 501, and the outrigger structure can be lifted away smoothly.

[0037] In summary, the leg riveting fixture of this embodiment solves the interference problem when the components and the fixture rotate relative to each other due to the offset between different components. The positioning position can be kept consistent every time, which is beneficial to improving production efficiency and production quality.

[0038] In some embodiments of this utility model, the positioning pin 204 is inserted into the column 200 and can be pulled outward under external force to separate from the support plate 501.

[0039] Specifically, the column 200 has two vertical plates 203 arranged along the first direction. The vertical plates 203 are L-shaped, and a connecting plate is provided between the two vertical plates 203. The L-shaped structure of the vertical plates 203 simplifies the structural composition, reduces weight, and facilitates the adjustment of the distance between the two columns 200. The upper end of the vertical plate 203 is provided with pin holes, and the positioning pins 204 are inserted into the two pin holes and extend to the side of the two columns 200 that are close to each other. The structural arrangement of this embodiment also facilitates the removal of the positioning pins 204, making it easy to separate them from the support plate 501.

[0040] Based on this structure, a smooth roller 205 is installed on the horizontal extension of the vertical plate 203 to form a first support platform. Using the smooth roller 205 to support the support leg plate 500 helps to reduce the contact area, thereby reducing friction and facilitating the movement and adjustment of the column 200 along the first direction while in the supported state.

[0041] Reference Figures 1 to 3 In some embodiments of this utility model, the outrigger riveting fixture further includes a third support platform 400. The third support platform 400 is fixedly mounted on the upper surface of the base frame 100 and located between the first support platform and the second support platform 300, thereby supporting the middle position of the outrigger upright plate 500. The third support platform 400 is provided with a support ramp and a first vertical reference surface 401, which are distributed along a first direction. The first vertical reference surface 401 matches the set position of the side wall of the outrigger upright plate 500. When the outrigger upright plate 500 is placed on the first support platform, the second support platform 300, and the third support platform 400, the support ramp first abuts against the outrigger upright plate 500, and under the action of gravity, guides the outrigger upright plate 500 towards the direction of the first vertical reference surface 401, so that the outrigger upright plate 500 abuts against the first vertical reference surface 401 and reaches the set position.

[0042] As can be seen from the structural configuration of the aforementioned embodiments, the first support platform is mounted on the column 200, which requires adjustment and movement. Furthermore, the support plate 501 and the leg plate 500 are misaligned along the first direction, making it difficult for the first support platform to position the leg plate 500. Simultaneously, the second support platform 300 primarily positions the other end of the leg plate 500 and the bushing 502 via a V-shaped positioning groove, making it also difficult to position the leg plate 500. Moreover, positioning the leg plate 500 from both ends easily leads to positioning deviations. This embodiment uses a first vertical reference surface 401 positioned at the midpoint of the leg plate 500's length for positioning. This design is simple, allows for rapid positioning of the leg plate 500, reduces positioning difficulty, and improves positioning accuracy.

[0043] In some embodiments of this utility model, the second support platform 300 is provided with a second vertical reference surface 303 on one side of the V-shaped positioning groove, and along the second direction, the second vertical reference surface 303 is flush with the first vertical reference surface 401. It can be understood that in this embodiment, by providing the second vertical reference surface 303, it can cooperate with the first vertical reference surface 401 to improve the positioning accuracy of the support leg plate 500.

[0044] In actual setup, the second vertical reference plane 303 can be misaligned with the V-shaped positioning groove along the second direction to ensure the exposure of the end hole of the bushing 502, which facilitates hoisting.

[0045] Reference Figure 1 In some embodiments of this utility model, the two columns 200 include a first column 202 and a second column 201. Along a first direction, the first column 202 and the first vertical reference plane 401 are located on the same side. The first column 202 is fixedly connected to the base frame 100, and the second column 201 moves along the first direction. By fixing one column 200 and movably setting the other column 200, the distance between the two can be easily adjusted.

[0046] Specifically, in some embodiments of this utility model, a slide rail and a lead screw adjustment mechanism are provided between the second column 201 and the base frame 100. The lead screw adjustment mechanism is used to adjust the movement of the second column 201 within the slide rail. The slide rail is located on the upper surface of the base frame 100 and is arranged along a first direction. The lower end of the second column 201 is slidably mounted within the slide rail. The sliding mounting method includes using a pulley structure, a guide post and guide sleeve structure, etc., which can be flexibly configured according to needs by those skilled in the art. The lead screw adjustment mechanism adopts a manually adjustable drive form.

[0047] During operation, first move the second column 201 to a position close to the first column 202, and install the support plate 501 on the first column 202 and the second column 201. After assembly, before lifting the outrigger structure from the bushing 502 position, first adjust the second column 201 away from the first column 202 so that the outrigger plate 500 is misaligned with the second column 201 in the first direction, and then lift the outrigger structure to avoid interference problems.

[0048] Reference Figure 1 In some embodiments of this utility model, the second support platform 300 is provided with two positioning plates 301 along the first direction. The upper ends of the two positioning plates 301 are recessed with V-shaped notches 302, forming V-shaped positioning grooves. Using the structure of this embodiment, the positioning plates 301 can abut against the forming openings on both sides of the support leg plate 500, allowing the bushing 502 to be directly inserted into the forming openings of the support leg plate 500, thus optimizing the structure and weight of the second support platform 300.

[0049] In some embodiments of this utility model, the two positioning plates 301 can be moved along a first direction to adjust the spacing, so as to adapt to the assembly operation of support leg structures of different sizes. Specifically, of the two positioning plates 301, the positioning plate 301 located on the same side as the first column 202 is fixedly mounted on the base frame 100, while the other positioning plate 301 is adjustablely mounted on the base frame 100, thereby realizing distance adjustment.

[0050] In some embodiments of this utility model, the support height of the first support platform can be adjusted vertically. Referring to the aforementioned embodiment of the optical roller 205, multiple mounting holes are vertically arranged on the vertical plate 203, and the support height is adjusted by mounting the optical roller 205 into different mounting holes.

[0051] It is understood that the tooling structure in this utility model is not limited to... Figure 4 The outrigger structure positioning shown is applicable to any situation where there is interference between the workpiece and the tooling when hoisting from one end. The interference can be avoided by adjusting the spacing.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
