Description

Technical Field

[0001] This invention relates to a welding fixture and manufacturing process, and more particularly to a welding fixture and manufacturing process for a detachable large-section tenon-type standard section. This fixture and process can complete the single-piece, single-piece, and integral forming of standard sections of similar structure with different sizes by using different positioning structural modules. Background Technology

[0002] Standard sections are an indispensable key component in power pole erection equipment. Although various types of standard sections have different cross-sections and structural forms, they are all required to have good interchangeability and relatively small dimensional and positional errors.

[0003] This patent addresses a standard section with a structure consisting of two tenon-jointed single pieces and various detachable support rods. The connection of this type of standard section requires both lateral pin connections and longitudinal end-face bearing capacity, while ensuring that the male and female joints at the connection points of the two sections do not interfere with each other. This places higher demands on the dimensional and positional errors of this type of standard section during manufacturing.

[0004] Based on these challenges, our company designed this tooling and process flow with a focus on optimizing processes, reducing costs, improving quality and efficiency, and ensuring product interchangeability. This tooling and process flow solves the manufacturing difficulties of this type of standard section. Its design concept and functions are mainly divided into three parts: first, K-type web member assembly function; second, single-piece assembly function; and third, single-piece assembly function. The tooling adopts a modular design, facilitating its application on standard sections of different sizes but with the same structure, as well as tooling maintenance. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide a welding fixture and manufacturing process for a detachable large-section tenon-type standard section that has a reasonable structural design, strong versatility, economic reliability, cost reduction, quality improvement and efficiency enhancement, and is easy to promote and mass-produce in batch production.

[0006] The technical solution adopted by this invention to solve the above problems is as follows: The assembly and welding fixture for the disassembled large-section tenon-type standard section includes interconnected K-type web member assembly and welding fixtures, standard section single-piece assembly and welding fixtures, and standard section single-piece assembly and welding fixtures. The K-type web member assembly and welding fixture includes a base platform, four equal-height plates, twelve ear plate spacers, and twelve pins. The standard section single-piece assembly and welding fixture includes a standard section single-piece joint ear plate positioning fixture, a standard section single-piece step positioning fixture, and a standard section node plate positioning fixture. The standard section single-piece joint ear plate positioning fixture includes a second base platform, two ear plate positioning supports, three pads, an ear plate positioning support, two joint pins, two transition plates, and a first clamping mechanism. The second ear plate positioning support and the ear plate positioning support are connected to the product joint through joint pins. The transition plates are placed between the product joint and the ear plate positioning support. Between the seats, the relative positions of the main chord members of the product are determined by the pads and ear plate positioning supports; the standard section single-step positioning fixture includes a contact plate, a step positioning base, a step positioning support, and eleven positioning pins. The contact plate and step positioning support are connected to the step positioning base by positioning pins; the standard section node plate positioning fixture includes four single-hole positioning plates, four double-hole positioning plates, three end-face positioning plates, a main square tube, and an end positioning plate. The single-hole positioning plates and double-hole positioning plates are connected to the product node plate by pins, and the end positioning plate is aligned with the end face of the main chord member as a reference; the standard section single-piece assembly welding fixture includes a base platform three, two positioning supports one, four positioning supports two, four positioning supports three, and two clamping mechanisms two. Positioning supports one, two, and three are all positioned and fastened to the base platform three by positioning pins and screws.

[0007] Preferably, the first clamping mechanism of the present invention includes a screw hole plate and a bolt connected to each other; the second clamping mechanism includes a transition seat, a screw hole shaft and a bolt connected to each other.

[0008] Preferably, the second positioning support of the present invention includes one positioning support, two steel sleeves and two pins; the third positioning support includes one positioning support, two positioning pins, four screws, four steel sleeves and one pin.

[0009] Preferably, the standard section single-step positioning fixture of the present invention is upside down on the side of the main chord of the product.

[0010] Preferably, the step positioning base of the present invention adopts a hollow structure.

[0011] Preferably, the present invention uses the hole positions of the base plate and the thickness of four equal-height plates to manufacture K-type web members of different sizes.

[0012] This invention also provides a manufacturing process for a detachable, large-section, tenon-type standard section, characterized in that: the specific manufacturing process is as follows: The standard section fabrication is broken down into K-type web member fabrication, standard section single-branch fabrication, and standard section single-piece fabrication. The fabrication of a single standard section is further divided into positioning of the joint lug plate of a single standard section, positioning of the step of a single standard section, and positioning of the node plate of a single standard section. The male and female connectors of the product are pre-drilled; on the standard section single connector ear plate positioning fixture, the connector is connected to the chord with the end face of the male connector side chord as the reference. Using the end face of the male connector side chord as a reference, the standard section step is positioned using a single step positioning fixture. On the standard section node plate positioning fixture, the node plate is positioned by a pin shaft; The positioning dimensions of the standard section single step positioning fixture and the standard section node plate positioning fixture are larger than the design dimensions, leaving a margin for subsequent processing; After welding and cooling, the standard section is transferred to the single-piece welding fixture to complete the assembly and welding of the standard section. When welding the node plate and web between two standard sections, weld the weld on one side first, and then weld the weld on the other side after removing the fixture to reduce welding deformation and improve product quality. After the standard section is cooled after welding, it is transferred to the whole machine. First, the male connector side end face is milled, then the female connector end face is milled with the male connector side end face as the reference to ensure the total length. Then, the connector ear plate hole position is machined in place with the two side end faces as the reference. Through the above complete set of tooling and process flow, we can efficiently produce standard sections of this type that meet interchangeability requirements in batches, thus achieving mass production.

[0013] Compared with existing technologies, this invention has the following advantages and effects: Using this tooling, standard sections of this type can be integrally formed in batch production, 1) improving and optimizing welding deformation; 2) solidifying the control of key components and improving product quality; 3) optimizing site layout; and 4) saving costs and improving work efficiency. It is suitable for mass production of this type of standard section. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments. Example

[0036] See Figures 1 to 6 The assembly and welding fixture for the detachable large-section tenon-type standard section in this embodiment includes a set of K-type web member assembly and welding fixture 1, a set of standard section single-piece assembly and welding fixture 2, and a set of standard section single-piece assembly and welding fixture 3 connected to each other.

[0037] like Figure 1 As shown, the K-type web member welding fixture 1 includes a base platform 11, four equal height plates 12, twelve ear plate spacers 13, and twelve pins 14.

[0038] K-type web members of different sizes are made using the holes in the base plate 11 and the thickness of the four equal-height plates 12.

[0039] In this embodiment, the spacer 13 has both the initial function of the steel sleeve and the function of equal height positioning.

[0040] In this embodiment, the standard section single-piece welding fixture 2 includes a standard section single-piece joint lug plate positioning fixture 21, a standard section single-piece step positioning fixture 22, and a standard section node plate positioning fixture 23.

[0041] In this embodiment, there are two components: a base platform 211, an ear plate positioning support 212, a pad 213, an ear plate positioning support 214, a connector pin 215, a transition plate 216, and a clamping mechanism 217. like Figure 2 As shown, the standard section single-joint ear plate positioning fixture 21 includes a base platform 211, two ear plate positioning supports 212, three pads 213, one ear plate positioning support 214, two joint pins 215, two transition plates 216, and a clamping mechanism 217.

[0042] In this embodiment, the ear plate positioning support 212 and ear plate positioning support 214 are connected to the product connector via the connector pin 215. The transition plate 216 is placed between the product connector and the ear plate positioning support 214 to determine the relative position of the product connector.

[0043] The relative position of the main chord of the product is determined by the pad 213 and the ear plate positioning support 214.

[0044] In this embodiment, the side of the ear plate positioning support 214 is machined, and the main chord of the product is made to fit against the side of the ear plate positioning support 214 by the clamping mechanism 217, so as to ensure the distance from the ear plate hole to the main chord of the product.

[0045] III. Figure 3 As shown, the standard section single-step positioning fixture 22 includes a contact plate 221, a step positioning base 222, a step positioning support 223, and eleven positioning pins 224.

[0046] In this embodiment, the standard section single-step positioning fixture 22 is upside down on the side of the main chord of the product.

[0047] In this embodiment, the step positioning support 223 is in contact with the step surface to determine the relative position of the step.

[0048] The hollow design of the step positioning base 222 in this embodiment provides space for riveting and welding, reduces weight, and facilitates use.

[0049] In this embodiment, the contact plate 221 and the step positioning support 223 are connected to the step positioning base 222 through the positioning pin 224.

[0050] like Figure 4As shown, the standard section node plate positioning fixture 23 includes four single-hole positioning plates 231, four double-hole positioning plates 232, three end face positioning plates 233, one main square tube 234, and one end positioning plate 235.

[0051] In this embodiment, the end positioning plate 235 is aligned with the end face of the main chord as a reference.

[0052] In this embodiment, the single-hole positioning plate 231 and the double-hole positioning plate 232 are connected to the product node plate by a pin to determine their relative positions.

[0053] In this embodiment, the hole diameters of the single-hole positioning plate 231 and the double-hole positioning plate 232 are smaller than the dimensions in the drawings, leaving room for subsequent drilling of the node plate.

[0054] In this embodiment, the distance between the single-hole positioning plate 231 and the double-hole positioning plate 232 and the end face of the main chord is larger than the dimensions in the drawing, leaving a margin for subsequent overall end face processing.

[0055] In this embodiment, the single-hole positioning plate 231 and the double-hole positioning plate 232 are machined on both sides to determine the opening distance between the product node plates.

[0056] like Figure 5 As shown, the standard section single-piece welding fixture 3 includes one base platform 31, two positioning supports 1 32, four positioning supports 2 33, four positioning supports 34, two clamping mechanisms 2 35, eight screws (omitted markings), and four positioning pins (omitted markings).

[0057] Positioning support 2 33 includes one positioning support, two steel sleeves, and one pin; positioning support 3 34 includes one positioning support, two positioning pins, four screws, two steel sleeves, and one pin; tightening mechanism 2 35 includes one transition seat, one screw hole shaft, and one bolt.

[0058] In this embodiment, positioning support 1 32, positioning support 2 33, and positioning support 34 are all positioned and fastened to base platform 3 31 by positioning pins and screws.

[0059] The side surface of positioning support 32 is machined by controlling the standard section to be flush with the side surface of positioning support 32, thereby controlling the external dimensions of the standard section.

[0060] After the position of the second positioning support 33 is determined by connecting it to a single standard section via a pin, the node plate at the diagonal position is positioned by the third positioning support 34.

[0061] like Figure 6 As shown, the components welded by the above tooling are assembled to complete the standard section of the detachable large-section electric pole type addressed by this patent.

[0062] The manufacturing process of this embodiment is as follows: Figures 7-20 As shown, the specific steps are as follows: The standard section fabrication process is broken down into K-type web member fabrication, single standard section fabrication, and single standard section fabrication.

[0063] The production of a single piece is further divided into joint ear plate positioning, step positioning, and node plate positioning.

[0064] The male and female connectors of the product are pre-drilled; on the standard section single connector ear plate positioning fixture 21, the connector is connected to the chord with the end face of the male connector side chord as the reference.

[0065] Using the end face of the male connector side chord as a reference, the standard section step is positioned using the single step positioning fixture 22.

[0066] The node plate is positioned using a pin on the standard section node plate positioning fixture 23.

[0067] The positioning dimensions of the standard section single step positioning fixture 22 and the standard section node plate positioning fixture 23 are larger than the design dimensions, leaving a margin for subsequent processing.

[0068] After welding and cooling, each standard section is transferred to a single-piece welding fixture to complete the assembly and welding of the standard section. When welding the node plate and web members between two standard sections, weld the weld on one side first, and then weld the weld on the other side after removing the fixture to reduce welding deformation and improve product quality.

[0069] After welding and cooling, the standard section is transferred to the whole machine. First, the male connector side end face is milled, then the female connector end face is milled with the male connector side end face as the reference to ensure the total length. Then, the connector ear plate hole positions are machined in place with the two side end faces as the reference.

[0070] Through the above complete set of tooling and process flow, it is possible to efficiently produce standard sections of this type that meet interchangeability requirements in batches, thus achieving mass production.

[0071] Based on the above description, those skilled in the art are already able to implement it.

[0072] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their parts and components. The above description is merely illustrative of the structure of the present invention. All equivalent or simple variations made based on the structure, features, and principles described in this patent concept are included within the protection scope of this patent. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to substitute them, as long as they do not deviate from the structure of the present invention or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
