Technical Field

[0001] The utility model relates to the technical field of supporting welding equipment, in particular to a tool for welding conveyor legs. Background Art

[0002] During the construction of the conveyor, the corresponding support legs need to be manufactured. Since a single conveyor requires a large number of support legs, the consistency of the support leg manufacturing is required to ensure the installation accuracy of the rollers used for logistics conveying above.

The first positioning assembly, the second positioning assembly, the third positioning assembly and the fourth positioning assembly enclose a welding cavity for accommodating the leg crossbar assembly.

[0004] This tooling can achieve stable parameter and tolerance control when producing a large number of leg crosspieces of the same size. However, in the above-mentioned patent, the support assembly arranged in the side guide groove, especially the support assembly installed with the fourth positioning assembly, will block the welding points located on the side of the leg, thereby making it difficult to carry out welding work at some positions smoothly.

[0011] As a further improvement of the present invention, the first clamping blocks and the supporting bottom block are connected via a spacing adjustment member for controlling a first spacing between the two groups of the first clamping blocks.

[0012] As a further improvement of the present invention, the spacing adjustment member includes a potential energy accumulation member for driving the two groups of the first clamping blocks closer together.

[0013] As a further improvement of the present invention, the lower connecting member fixing kit includes two groups of second clamping blocks, a limit block and a supporting block, wherein the two groups of the second clamping blocks are respectively arranged on both sides of the support column to form a second clamping space for accommodating the lower connecting member of the conveyor leg. The limit block and the supporting block are arranged on the side wall of the support column, and the supporting block is used to support the lower connecting member. When the limit block conflicts with the lower connecting member, the lower connecting member is driven close to the end of the main body.

[0014] As a further improvement of the present invention, the upper connecting member fixing kit includes an extension block and two groups of third clamping blocks arranged at one end of the extension block, wherein the other end of the extension block is movably installed with the support column; the two groups of third clamping blocks are arranged on both sides of the extension block, and a third clamping space for accommodating the upper connecting member of the conveyor leg is formed between the two groups of third clamping blocks.

[0026] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0027] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0028] In the welding work of the conveyor leg A, the tooling provided by the present invention is used to perform preliminary assembly of the various components of the conveyor leg A. Figure 1As shown, the conveyor leg A consists of three main components: a main body A01, an upper connector A03, and a lower connector A02. Both the upper connector A03 and the lower connector A02 are located at the ports at both ends of the main body A01, with the upper connector A03 positioned at the top and the lower connector A02 at the bottom. The welding points A04 between the upper connector A03, the lower connector A02, and the main body A01 are primarily located at the junction of the sides of the main body A01 and the lower connector A02.

[0029] Example 1:

[0030] This embodiment provides a tool for welding conveyor legs, such as Figures 2 and 3 As shown, it mainly includes a base 1, six support columns 2, and a main body fixing kit 5, an upper connecting piece fixing kit 3 and a lower connecting piece fixing kit 4 arranged on the corresponding support columns 2. Figure 7 As shown, a reference line α is defined on the base 1 , and in this embodiment, a total of six support columns 2 are arranged along the reference line α.

[0031] The reference line α is the reference for the layout of the various components of the tooling. Therefore, after the various components of the conveyor leg A are initially assembled through the tooling, the relative positional relationship between the various components of the conveyor leg A and the reference line α is also fixed, which ensures good processing consistency during the processing of a large number of conveyor legs A.

[0032] In the six supporting columns 2 arranged in this embodiment, Figures 2 and 3 As shown, the two support columns 2 near the endpoints of reference line α are each provided with an upper connector fixing kit 3, the two support columns 2 relatively close to the midpoint of reference line α are each provided with a lower connector fixing kit 4, and the two support columns 2 closest to the midpoint of reference line α are each provided with a main body fixing kit 5. The main body fixing kit 5, the upper connector fixing kit 3, and the lower connector fixing kit 4 enclose a welding cavity that accommodates the conveyor leg A.

[0033] like Figure 2 As shown, when the various components of the conveyor leg A are initially assembled, the support column 2 near the midpoint of the reference line α is fixed to the main body A01 through the main body fixing kit 5. The support column 2 equipped with the upper connecting piece fixing kit 3 and the support column 2 equipped with the lower connecting piece fixing kit are both placed near the end of the main body A01, thereby respectively fixing the upper connecting piece A03 and the lower connecting piece A02 provided at the end of the main body A01. To ensure that the upper connecting piece fixing kit 3 and the lower connecting piece fixing kit 4 do not interfere with each other, the support column 2 equipped with the upper connecting piece fixing kit 3 is closer to the end point of the reference line α, that is, further away from the position where the main body A01 is located.

[0034] The tooling in this embodiment ensures that the support column 2 and various fixing kits will not obstruct the welding point A04 between the upper connecting part A03, the lower connecting part A02 and the main body A01, on the premise that the various components of the conveyor leg A can be preliminarily assembled, which is conducive to the smooth progress of the welding work.

[0035] Preferably, if Figure 7 As shown, sixteen groups of mounting points 101 are arranged on the base 1 along the reference line α. In this embodiment, each group of mounting points 101 includes a pair of mounting holes 101-1 symmetrically arranged relative to the reference line α. Figures 2 and 3 As shown, the bottom of each of the six support columns 2 is provided with a mounting base 201, and the mounting base 201 can be mounted on the mounting point 101. In this embodiment, the mounting base 201 is provided with a through hole. When the mounting base 201 is placed, the through hole is connected to the mounting hole 101-1. At this time, a fixing structure such as a bolt can be inserted to achieve the installation and fixation of the mounting base 201 and the support column 2 on the base 1.

[0036] The structure for matching the mounting point 101 and the mounting base 201 may also be any detachable mounting kit structure such as a mounting notch and a mounting block.

[0037] Under the above structure, the position of each support column 2 can be adjusted according to the length and other dimensions of the conveyor leg A, so that the tooling can be adapted to the preliminary assembly work of conveyor leg A components of different sizes, thereby expanding the scope of application of the tooling.

[0038] Preferably, if Figure 7 As shown, a guide groove 102 is further provided on the base 1 along the reference line α. In this embodiment, the mounting point 101 is in the form of a mounting hole 101 - 1 , so two symmetrical mounting holes 101 - 1 are respectively placed on both sides of the guide groove 102 .

[0039] Correspondingly, such as Figures 2 and 3 As shown, the bottom of the mounting base 201 is provided with a guide block 202 that engages within the guide groove 102. This allows the mounting base 201, and therefore the support column 2 thereon, to slide along the guide groove 102 to the desired position. The structure within the mounting base 201, located on the base 1, then connects to the mounting point 101, ultimately securing the support column 2. This structure ensures that the support column 2 does not deviate significantly from the reference line α during position adjustment, reducing errors associated with position adjustment.

[0040] Preferably, if Figure 4As shown, the main body fixing kit 5 includes a supporting base block 501 and two sets of first clamping blocks 502 disposed on either side of the supporting base block 501. In this embodiment, the two sets of first clamping blocks 502 are symmetrically disposed on either side of a reference line α, forming a first clamping space therebetween to accommodate the main body A01 of the conveyor leg A. When the main body A01 is placed in the first clamping space, the two sets of first clamping blocks 502 abut against both sides of the main body A01 to form a clamp, thereby securing the main body A01.

[0041] Preferably, the first clamping block 502 and the supporting bottom block 501 are connected by a spacing adjustment member 503, which is used to control the first spacing between the two groups of first clamping blocks 502. The spacing adjustment device can adopt any adjustable component such as a telescopic rod, a telescopic frame, etc. that can maintain the first spacing. In this embodiment, a telescopic rod structure is adopted. When the first spacing is reduced, the connecting rod is stored in the cavity opened in the supporting bottom block 501. This structure ensures that the main body fixing kit 5 can clamp and limit the main body A01 of different sizes, thereby expanding the scope of application of the tooling.

[0042] Preferably, the spacing adjustment member 503 includes a potential energy accumulator 504, which in this embodiment is a spring component, which is sleeved outside the connecting rod. This spring component can drive the two sets of first clamping blocks 502 toward each other without external force. Therefore, when the two sets of first clamping blocks 502 are inserted between the main body A01, they can drive the first clamping blocks 502 and the side surfaces of the main body A01 to closely fit, further ensuring the secure clamping and fixation.

[0043] Preferably, the lower connecting member fixing kit 4 includes two sets of second clamping blocks 401 , a limiting block 402 and a supporting block 403 .

[0044] like Figure 5 As shown, two sets of second clamping blocks 401 are respectively disposed on either side of the support column 2. In this embodiment, they are symmetrically arranged on either side of the reference line α. A second clamping space is formed between the two sets of second clamping blocks 401. When the lower connecting member A02 is placed therein, the two sets of second clamping blocks 401 can tightly fit with both sides of the lower connecting block to form a clamping and fixing effect. In this case, the lower connecting block is fixed in a direction perpendicular to the reference line α.

[0045] In this embodiment, the limit block 402 and the support block 403 are arranged on the side wall of the support column 2, close to the end point of the reference line α. Figure 2As shown, when the lower connector A02 is placed, the support block 403 placed at the bottom of the lower connector A02 provides support and secures the lower connector A02 in its vertical position. The limit blocks 402 are placed on both ends of the upper connector fixing assembly 3 to cooperate with each other. The limit blocks 402 provided by the two upper connector fixing assembly 3 together form a clamping effect, driving the lower connector A02 closer to the end of the main body A01, thereby securing the lower connector A02 in the direction of the reference line α.

[0046] The mutual cooperation between the two sets of second clamping blocks 401, the supporting blocks 403 and the limiting blocks 402 ensures that the position of the lower connecting part A02 is fixed. At the same time, the three types of components do not block the welding points between the lower connecting part A02 and the main body A01, which is conducive to the smooth development of the welding work.

[0047] Preferably, the upper connecting member fixing kit 3 includes an extension block 301 and two sets of third clamping blocks 302. Figure 6 As shown, one end of the extension block 301 is provided with two groups of third clamping blocks 302 , and the other end is movably connected to the support column 2 .

[0048] The movable connection method can adopt a detachable connection method such as a socket-and-socket connection, or a connection method such as a hinged structure. In this structure, the upper connection fixing kit can be completely removed from the tooling, the upper connector A03 can be fixedly installed in the upper connection fixing kit, and then the upper connection fixing kit can be returned to the tooling to complete the preliminary assembly of the various parts of the conveyor leg A. In addition, if the movable connection method of the extension block 301 adopts a detachable connection method such as a socket-and-socket connection, different specifications of the upper connector fixing kit 3 can be selected to fix the upper connector A03 according to the size of the upper connector A03. The upper connector fixing kit 3 can then be installed on the support column 2 during use of the tooling, thereby expanding the applicability of the tooling.

[0049] In this embodiment, the movable connection adopts a hinged form.

[0050] In the upper connection and fixing assembly, two sets of third clamping blocks 302 are positioned on either side of the extension block 301. In this embodiment, the two sets of third clamping blocks 302 are symmetrically positioned on either side of the reference line α, creating a corresponding third clamping space between them. When the upper connector A03 is placed in the third clamping space, the two sets of third clamping blocks 302 tightly adhere to the sides of the upper connection block, providing a secure clamping effect.

[0051] The above structure realizes the fixation of the upper connecting member A03 and completes the preliminary assembly of the conveyor leg A without causing any obstruction to the welding point between the upper connecting member A03 and the main body A01, which is conducive to the smooth development of the welding work.

[0052] Preferably, if Figures 2 and 3 As shown in FIG6 , a limited auxiliary block 303 is provided on one side of the third clamping block 302 close to the third clamping space. The structure of the upper connecting member A03 is as follows: Figure 1 As shown, there is a groove on it. Therefore, when the two groups of third clamping blocks 302 clamp the upper connecting part A03, the limiting auxiliary block 303 can be embedded in the groove of the upper connecting part A03. Then, when the upper connecting part A03 is installed on the support column 2, the limiting auxiliary block 303 fixes the upper connecting part A03 in the direction of the reference line α, further enhancing the fixing accuracy of the upper connecting part A03.

[0053] Preferably, if Figures 2 and 3 As shown in Figure 6, the side of the limiting auxiliary block 303 has a positioning edge 303-1 with an inclined structure. This structure ensures that the movement of the limiting auxiliary block 303 is guided during the embedding process of the groove, ensuring the smooth implementation of the embedding process.

[0054] Example 2:

[0055] The difference between this embodiment and embodiment 1 is that, in this embodiment, spacing adjustment members are provided on the connection structure between the second clamping block 401 and the support column 2, and between the third clamping block 302 and the extension block 301, and potential energy accumulation members are provided in the spacing adjustment members 503. In this embodiment, the spacing adjustment members adopt a telescopic rod structure, and spring components are provided on the outside of the connecting rods. The above-mentioned spring components can respectively drive the two groups of second clamping blocks 401 and the two groups of third clamping blocks 302 to approach each other. In this embodiment, since each clamping block is symmetrically arranged with respect to the reference line α, it is actually driven to approach the position of the reference line α when there is no external force.

[0056] On the one hand, the proximity of each group of clamping blocks to each other can drive the second clamping block 401 and the third clamping block 302 to actively clamp the corresponding objects, further ensuring the firmness of the clamping and fixing, while ensuring that the upper connecting piece fixing kit 3 and the lower connecting piece fixing kit 4 can also clamp the main body A01 of different sizes, expanding the scope of application of the tooling.

[0057] On the other hand, when each group of clamping blocks completes the clamping work of the main body A01, the upper connecting part A03 and the lower connecting part A02 respectively, the central axis of each component is driven to coincide with the reference line α, which actually makes the central axis of each fixing kit on the same straight line, ensuring that the conveyor leg A has a high installation accuracy after the initial assembly is completed. At the same time, during the welding process of a large number of conveyor legs A, the processing consistency is guaranteed, and the assembly accuracy of subsequent conveyors is improved.

[0058] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
