Abstract
Description
Technical Field
[0001] This utility model relates to the field of assembly and welding technology of I-shaped cross-section components, and in particular to an assembly and positioning fixture for I-shaped cross-section components. Background Technology
[0002] When welding I-shaped cross-section components, the web and two flanges need to be welded together to form an "I" shape. Currently, during welding, the web and two flanges are positioned manually using temporary supports. Manual measurement is prone to web skew and flange misalignment, and repeated adjustments to the supports are time-consuming and labor-intensive. Furthermore, the temporary supports lack sufficient rigidity, affecting the camber accuracy. Therefore, in view of the above situation, there is an urgent need to develop an assembly and positioning fixture for I-shaped cross-section components that allows for rapid positioning and easy splicing of the various components, improves the efficiency of subsequent welding work, reduces labor intensity, and ensures manufacturing quality. This fixture would overcome the shortcomings of current practical applications and meet current needs. Utility Model Content
[0003] The purpose of this invention is to provide an assembly and positioning fixture for I-shaped cross-section components to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An assembly and positioning fixture for I-shaped cross-section components includes auxiliary positioning fixtures, connecting plates, and bolts. Multiple auxiliary positioning fixtures are provided, and adjacent auxiliary positioning fixtures are detachably and fixedly connected by connecting plates and bolts. Each auxiliary positioning fixture includes a base plate, columns, jacks, and an adjustable support mechanism. A column is fixed to both the left and right ends of the upper side of the base plate. A jack is fixedly installed on the column located at the left end of the base plate, and an adjustable support mechanism is installed on the right side of the jack on the base plate.
[0006] Preferably, the adjustable support mechanism includes: a base, a support plate, screws, and hexagonal nuts. The base is fixedly installed on the bottom plate, the support plate is located above the base, and the bottom of the support plate is fixed with multiple screws penetrating the base. Each screw is equipped with two hexagonal nuts, one of which is located on the upper side of the base and the other on the lower side of the base.
[0007] Preferably, a shim plate is installed on the column located at the right end of the base plate. The shim plate is located at the lower left of the column and is detachably connected to the column by screws.
[0008] The beneficial effects of this utility model are as follows: This assembly and positioning fixture for I-shaped cross-section members allows for adjustment of the number of auxiliary positioning fixtures connected together according to the length of the I-shaped cross-section members to be assembled and welded, thereby adjusting the overall length to meet different usage requirements. When the two flanges of the I-shaped cross-section members to be welded and assembled are of equal length, there is no need to install a shim plate. In this case, the web of the I-shaped cross-section member is placed on the support plate, one of the two equal-length flanges is attached to the column on the right side of the base plate, and the other is placed on the right side of the jack. The jack is used to tighten the equal-length flange, making it tightly adhere to the web, thus ensuring that the two equal-length flanges are aligned with the web. The left and right ends are tightly fitted together to complete the positioning. Then, a person uses a welding device to weld from the joint between the equal-length flange plate and the web plate. When the two flange plates are of different lengths, the shorter flange plate is fitted to the column at the right end of the base plate, and the bottom of the shorter flange plate is supported by a shim plate to raise its height and prevent it from being suspended in the air. Then, the longer flange plate is placed on the jack and tightened by the jack before welding. Alternatively, loosening the hexagonal nut on the screw rod allows the support plate and screw rod to be moved up and down, thereby adjusting the height of the support plate to meet the needs of I-shaped cross-section components of different heights. After adjustment, the hexagonal nut is tightened to push it onto the base platform. In summary, this utility model facilitates the rapid positioning and splicing of various components of the I-shaped cross-section component, improves the efficiency of subsequent welding work of the I-shaped cross-section component, reduces labor intensity, and ensures manufacturing quality.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Specific implementation examples are given below.
[0018] See Figures 1-3 In this embodiment of the utility model, an assembly and positioning fixture for an I-shaped cross-section component includes an auxiliary positioning fixture 1, a connecting plate 2, and bolts 3. There are multiple auxiliary positioning fixtures 1. Two adjacent auxiliary positioning fixtures 1 are detachably and fixedly connected by the connecting plate 2 and bolts 3. The number of auxiliary positioning fixtures 1 connected together is adjusted according to the length of the I-shaped cross-section component to be assembled and welded, thereby adjusting the overall length to meet different usage requirements.
[0019] The auxiliary positioning fixture 1 includes: a base plate 11, columns 12, jacks 13, and an adjustable support mechanism 14. A column 12 is fixed to each of the upper left and right ends of the base plate 11. A jack 13 is fixedly installed on the column 12 located at the left end of the base plate 11. An adjustable support mechanism 14 is installed on the right side of the jack 13 on the base plate 11. In use, the web of the I-shaped cross-section member is placed on the adjustable support mechanism 14. One of the two equal-length flanges is attached to the column 12 on the right side of the base plate 11, and the other is placed on the right side of the jack 13. The jack 13 presses the equal-length flange tightly against the web, thus ensuring that the two equal-length flanges are tightly fitted to the left and right ends of the web, completing the positioning. Then, a person uses a welding device to weld the equal-length flanges to the web.
[0020] The adjustable support mechanism 14 includes: a base 141, a support plate 142, screws 143, and hexagonal nuts 144. The base 141 is fixedly installed on the base plate 11. The support plate 142 is located above the base 141 and is used to support the web. The bottom of the support plate 142 is fixed with multiple screws 143 that penetrate the base 141. Each screw 143 is equipped with two hexagonal nuts 144, with one hexagonal nut 144 located on the upper side of the base 141 and the other on the lower side of the base 141. In use, the hexagonal nuts 144 on the screws 143 are loosened first, and the support plate 142 and screws 143 can be moved up and down to adjust the height of the support plate 142 to meet the needs of I-shaped cross-section members of different heights. After adjustment, the hexagonal nuts 144 are tightened to push against the base 141.
[0021] See Figures 4-5 In this embodiment of the present invention, an assembly and positioning fixture for an I-shaped cross-section component is provided. A shim plate 15 is installed on the column 12 at the right end of the base plate 11. The shim plate 15 is located at the lower left of the column 12. The shim plate 15 is detachably connected to the column 12 by screws. When the two flanges of the I-shaped cross-section component to be assembled are of different lengths, the shorter flange is attached to the column 12 at the right end of the base plate 11, and the bottom of the shorter flange is supported by the shim plate 15 to raise its height and prevent its bottom from being suspended.
[0022] Working Principle: This assembly and positioning fixture is used for I-shaped cross-section components. During use, the number of auxiliary positioning fixtures 1 connected together is adjusted according to the length of the I-shaped cross-section component to be assembled and welded, thereby adjusting the overall length to meet different usage requirements. When the two flanges of the I-shaped cross-section component to be welded and assembled are of equal length, the shim plate 15 is not required. In this case, the web of the I-shaped cross-section component is placed on the support plate 142, one of the two equal-length flanges is attached to the column 12 on the right side of the base plate 11, and the other is placed on the right side of the jack 13. The jack 13 tightens the equal-length flange, making it firmly attached to the web, thus ensuring that the two equal-length flanges are tightly fitted to the left and right ends of the web, completing the assembly. Position the flanges, then use a welding device to weld them together at the joint of the equal-length flanges and the web. When the two flanges are of different lengths, attach the shorter flange to the column 12 at the right end of the base plate 11, and use the shim plate 15 to support the bottom of the shorter flange and raise its height to prevent it from being suspended. Then place the longer flange on the jack 13 and tighten it with the jack 13 before welding. Alternatively, loosen the hexagonal nut 144 on the screw 143 to move the support plate 142 and the screw 143 up and down, thereby adjusting the height of the support plate 142 to meet the needs of I-shaped cross-section components of different heights. After adjustment, tighten the hexagonal nut 144 to push it onto the base 141.
[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
