Description

Technical Field

[0001] The utility model relates to the field of chain processing, in particular to a welding tool used for a middle flat plate of a plate-belt conveyor belt. Background Art

[0002] In the context of production and operation automation, the use of conveyor belts is becoming more and more common. Plate conveyor belts are one of the common types of conveyor belts. They have the advantages of high strength and strong load-bearing capacity and are widely used in mechanical processing, food processing, logistics, packaging and other industries.

[0003] Chain conveyor belts usually consist of two parallel chains with a plate belt connected between them. Figure 1 and Figure 2 As shown, the strip is composed of several intermediate plates 1, which correspond one to each of the chain links on either side. The intermediate plates 1 include a base plate 11, with connecting plates 13 at both ends for connecting to the corresponding chains. Splicing shafts 12 are provided on either side of the base plate 11, and the splicing shafts 12 on both sides are staggered to facilitate sequential splicing into the strip.

[0004] The Chinese utility model patent with authorization announcement number CN217457456U discloses a novel chain plate conveyor belt and elevator, comprising a plurality of chain plates, each of which comprises a chain plate body. The front and rear edges of the chain plate body are respectively provided with a plurality of relatively staggered first and second plug-in blocks. The first and second plug-in blocks are provided with insertion holes on both sides thereof, through which insertion rods are slidably inserted into the insertion holes, so that the plurality of chain plates are hingedly connected to form a chain plate conveyor belt. The bottom surface of the chain plate body is provided with a first fixed portion and a second fixed portion at both ends thereof. The lower outer sides of the first and second fixed portions are provided with a first sliding portion and a second sliding portion extending to both sides thereof, so that a sliding groove is formed between the chain plate body and the first and second sliding portions. The chain plate is the intermediate plate of this application, and the structure of the intermediate plate is disclosed in the above application.

[0005] The spliced shafts and connecting plates in the intermediate plates are welded to the base plate. Because the intermediate plates need to be spliced together and connected to the matching chain links, the welding accuracy between the spliced shafts and connecting plates and the intermediate plates is crucial. Even the slightest deviation will cause the entire structure to become tight, directly affecting the assembly difficulty and operational reliability of the conveyor belt. Therefore, it is necessary to design a welding tool to reduce the difficulty of welding the intermediate plates and ensure welding quality. Summary of the Invention

[0006] The technical problem to be solved by the utility model is to provide a welding tool for the middle plate of a plate-belt conveyor belt, which can accurately position and reliably limit the base plate, connecting plate and splicing shaft cylinder respectively, effectively improve the welding accuracy, and has the advantages of simple structure and easy use.

[0007] In order to solve the above technical problems, the technical solution provided by the present utility model is as follows: a welding tool for the middle plate of a plate-belt conveyor belt, comprising a bottom plate, wherein the bottom plate is provided with a base plate mounting area;

The series of straight rods correspond to the lateral positioning units one by one; each lateral positioning unit corresponds to at least one clamping member, and the clamping member is used to limit the series of straight rods within the limiting groove.

[0011] During welding, the substrate is first placed into the substrate mounting area. The substrate end and side positioning blocks limit the substrate's horizontal position. Because the intermediate plates are connected via a connecting plate and splicing sleeves, the substrate's positioning accuracy requirements are relatively low, limited to a certain range.

[0012] Next, a specific number of splicing sleeves are inserted into the tandem rods. After adjusting the spacing, the tandem rods are placed on the baseplate's lateral positioning blocks to ensure a one-to-one alignment between the splicing sleeves and the splicing sleeve mounting areas. The tandem rods are then compressed using clamps. Finally, the connecting plate is installed, and the baseplate end positioning blocks and the connecting plate positioning blocks position the connecting plate. These blocks position the connecting plate, while the baseplate lateral positioning blocks and clamping assembly position and clamp the splicing sleeves, ensuring accurate positioning.

[0013] The clamping tooling of the present application has a simple structure, is easy to operate, and has a good promotion prospect.

[0014] Preferably, a backing plate is detachably connected to the bottom plate, and the backing plate is arranged in the base plate installation area. By arranging backing plates of different thicknesses, the installation height of the base plate can be adjusted to better cooperate with the splicing sleeve and the connecting plate.

[0015] Preferably, the substrate end positioning block and the connection plate positioning block are integrally or separately arranged.

[0016] Preferably, the bottom plate is provided with an end slot, and the base plate end positioning block and the connecting plate positioning block are detachably connected to the bottom plate through the end slot.

[0018] Preferably, the substrate lateral positioning blocks in the two lateral positioning units are staggered left and right.

[0019] Preferably, the clamping members correspond one-to-one with the lateral positioning blocks of the substrate, which effectively ensures the clamping reliability and can help to withstand welding stress and reduce welding deformation to a certain extent.

[0020] Preferably, the base plate includes at least two end segments and at least one middle segment, the middle segment is located between the two end segments and is separately arranged; the end positioning unit is arranged on the end segment, and the end segment and the middle segment are respectively provided with lateral positioning units.

[0021] The welding requirements of products with different length specifications can be met by increasing or decreasing the number of intermediate segments. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0032] like Figure 3-Figure 5 As shown, a welding fixture for the intermediate plate of a plate-belt conveyor belt includes a base plate 3, which is provided with a base plate mounting area 34. A backing plate 31 is detachably connected to the base plate 3 and disposed within the base plate mounting area 34. By providing backing plates 31 of varying thickness, the base plate mounting height can be adjusted to better mate with the splicing sleeve and connecting plate.

[0033] like Figure 3-Figure 6 As shown, end positioning units 5 are respectively provided at both ends of the substrate mounting area 34. The end positioning units 5 include a substrate end positioning block 51 and a connecting plate positioning block 52. The connecting plate positioning block 52 is located on one side of the substrate end positioning block. The connecting plate positioning block 52 is provided with a connecting plate positioning groove 53 on the side facing the substrate end positioning block. The substrate end positioning block 51 and the connecting plate positioning block 52 are provided integrally or separately.

[0034] like Figure 3 、 Figure 4 、 Figure 5 and Figure 7As shown, lateral positioning units are provided on both sides of the substrate mounting area 34. These lateral positioning units include a plurality of substrate lateral positioning blocks 6, which are spaced sequentially along the sides of the substrate mounting area 34. A splicing shaft barrel mounting area is formed between each pair of adjacent substrate lateral positioning blocks 6. Limiting grooves 61 are provided through the upper surfaces of the substrate lateral positioning blocks 6. The limiting grooves 61 on each substrate lateral positioning block 6 within the same lateral positioning unit are coaxially arranged. Specifically, the substrate lateral positioning blocks 6 in the two lateral positioning units are staggered left and right.

[0035] As a specific implementation method, Figure 5 、 Figure 8 and Figure 9 As shown, the bottom plate 3 is provided with end slots 32, through which the base plate end positioning blocks 51 and the connecting plate positioning blocks 52 are detachably connected to the bottom plate 3. The bottom plate 3 is provided with lateral slots 33, through which the base plate lateral positioning blocks 6 are detachably connected to the bottom plate 3. Appropriate end positioning units and lateral positioning units can be selected according to product specifications.

The serial straight rods 4 correspond one-to-one with the lateral positioning units; each lateral positioning unit corresponds to at least one clamping member 2, which is used to constrain the serial straight rods 4 within the limiting grooves 61. As a specific embodiment, the clamping members 2 correspond one-to-one with the substrate lateral positioning blocks 6, effectively ensuring clamping reliability and, to a certain extent, helping to withstand welding stress and reduce welding deformation.

[0037] During welding, the substrate is first placed in the substrate mounting area 34, and the substrate is horizontally limited by the substrate end positioning block 51 and the substrate side positioning block 6. Since the middle plate is connected by the connecting plate and the splicing sleeve, the positioning accuracy of the substrate is relatively low and can be limited to a certain range.

[0038] A specific number of splicing sleeves are then inserted into the tandem straight rods 4. After adjusting the spacing, the tandem straight rods 4 are placed on the baseplate lateral positioning blocks 6 to ensure a one-to-one alignment between the splicing sleeves and the splicing sleeve mounting areas. The tandem straight rods 4 are then compressed using the clamping members 2. Finally, the connecting plate is installed, and the baseplate end positioning blocks 51 and the connecting plate positioning blocks 52 position the connecting plate. These baseplate end positioning blocks 51 and the connecting plate positioning blocks 52 position the connecting plate, while the baseplate lateral positioning blocks 6 and the clamping assembly position and clamp the splicing sleeves, ensuring accurate positioning.

[0039] Further, such as Figure 8As shown, as a specific embodiment, the base plate 3 is an integrated type.

[0040] like Figure 9 As shown in the figure, as another specific embodiment, the base plate 3 includes at least two end segments 35 and at least one intermediate segment 36. The intermediate segment 36 is located between the two end segments 35 and is provided separately. The end positioning units 5 are provided on the end segments 35, and the end segments 35 and intermediate segment 36 are each provided with lateral positioning units. By increasing or decreasing the number of intermediate segments 36, the welding requirements of products of different lengths can be met.

[0041] The clamping tooling of the present application has a simple structure, is easy to operate, and has a good promotion prospect.

[0042] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
