Description

Technical Field

[0001] The utility model relates to the technical field of connector welding, in particular to a connector positioning welding tool. Background Art

[0002] The connector is mainly used in the longitudinal prestressed anchoring system of cast-in-place beams to connect and extend the prestressed beams. During the construction process, the connector can be used to tension and anchor the prestressed beam at one end, and then install the extended prestressed beam to complete the connection of the prestressed beam. During the construction process, the installation of the connector is very critical. First, the prestressed beam at one end needs to be tensioned and anchored to ensure its stability and reliability. Then, the connector is installed on the tensioned and anchored prestressed beam, and then the long prestressed beam is installed and fixed with a prestressed anchor. Finally, the extended prestressed beam is tensioned to form a tight connection with the anchored prestressed beam.

[0003] In the prior art, the connector mainly includes a gasket and a connecting plate. The gasket in the integral connector currently available on the market is a conical honeycomb structure. Generally, after the connecting plate and the gasket are transported to the construction site, they are connected by bolts or welding. However, when bolted, the gasket and the connecting plate can be fixed, and it cannot be guaranteed that the holes between the gasket and the connecting plate correspond to each other one by one. If the gasket and the connecting plate are directly aligned and welded, it is also easy to cause the gasket and the connecting plate to shift, resulting in a biased hole phenomenon, which greatly affects the subsequent threading operation. Utility Model Content

[0004] In order to solve the above technical problems, the utility model utilizes a detachable limiting shaft to be inserted into the corresponding positioning hole and limiting hole to realize the positioning welding of the gasket and the connecting plate. The specific technical solution is as follows:

[0005] A connector positioning welding tool is used for positioning welding of a gasket and a connecting plate, including a welding part, a welding disk and a limiting shaft detachably mounted on one side of the welding disk, the limiting shafts are at least three in number, and several of the limiting shafts are inserted into corresponding holes of the gasket and the connecting plate, so that the gasket, the connecting plate and the welding disk are fitted in sequence.

[0006] Preferably, a plurality of mounting holes are provided on the welding plate, and the limiting shaft is plugged into the corresponding mounting holes.

[0007] Preferably, a plurality of mounting holes are formed on the welding plate, and the limiting shaft is threadedly connected to the corresponding mounting holes.

[0008] Preferably, the gasket includes a ring body and positioning holes opened on both sides of the ring body, and the limiting shaft passes through the positioning holes.

[0009] Preferably, the connecting plate comprises a plate body and limiting holes opened on both sides of the plate body, and the limiting holes correspond to the positioning holes.

[0010] Preferably, an end of the limiting hole away from the gasket is provided with a tapered hole inclined outwards.

[0011] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0012] By setting a detachable limit shaft, the limit shaft is inserted into the corresponding positioning hole and limit hole to realize the positioning of the gasket and the connecting plate. The tapered hole can guide the end of the limit shaft, making it easier to insert the limit shaft into the limit hole. The ring body and the plate body are in contact, and subsequent welding operations can be performed to avoid biased holes caused by subsequent welding, which affects the threading operation.

[0016] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0017] like Figure 1 and Figure 2 As shown, a connector positioning welding tool is used for positioning welding of a gasket 10 and a connecting plate 20, including a welding part 30, which includes a welding disk 301 and a limiting shaft 303 detachably installed on one side of the welding disk 301, and the number of limiting shafts 303 is at least three. Several limiting shafts 303 are inserted into the corresponding holes of the gasket 10 and the connecting plate 20, so that the gasket 10, the connecting plate 20 and the welding disk 301 are sequentially fitted. If it is necessary to weld the gasket 10 and the connecting plate 20, the gasket 10 and the connecting plate 20 are first stacked, and the limiting shaft 303 is inserted into the gasket 10 and the connecting plate 20, so that the position of the gasket 10 and the connecting plate 20 can be positioned, and subsequent welding operations can be performed.

[0018] like Figure 2As shown, a plurality of mounting holes 302 are provided on the welding disk 301, and the limiting shaft 303 is plugged or threadedly connected to the corresponding mounting holes 302, wherein the limiting shaft 303 can be detached from the welding disk 301, so that it is convenient to install according to needs and the convenience of disassembly is improved. If the limiting shaft 303 is inserted through the gasket 10 and the connecting plate 20 by plugging, the limiting shaft 303 is clearance-matched with the gasket 10 and the connecting plate 20, and the limiting shaft 303 is interference-fitted with the welding disk 301, so that it is convenient to position and weld for subsequent disassembly; if a threaded connection method is adopted, one end of the limiting shaft 303 is threadedly fixed to the mounting hole 302 by a threaded method, and then the limiting shaft 303 is inserted into the gasket 10 and the connecting plate 20, and the gasket 10 and the connecting plate 20 are position-welded, which is also convenient for subsequent disassembly.

[0019] like Figure 2 As shown, the gasket 10 includes a ring body 101 and a positioning hole 102 provided in the ring body 101, and the limiting shaft 303 passes through the positioning hole 102. The connecting plate 20 includes a plate body 201 and a limiting hole 202 provided in the plate body 201, and the limiting hole 202 corresponds to the positioning hole 102, wherein the limiting shaft 303 is inserted into the corresponding positioning hole 102 and the limiting hole 202 to achieve the positioning of the gasket 10 and the connecting plate 20. The limiting hole 202 is provided with a tapered hole 203 inclined outward at one end away from the gasket 10, and the tapered hole 203 can guide the end of the limiting shaft 303, making it easier for the limiting shaft 303 to be inserted into the limiting hole 202.

[0020] The number of mounting holes 302 can be several times the number of positioning holes 102 or limiting holes 202. Since the number of positioning holes 102 and limiting holes 202 is the same, the mounting holes 302 can be set to be several times the number of positioning holes 102 or limiting holes 202. When it is necessary to position a different number of subsequent positioning holes 102 or limiting holes 202, it is only necessary to change the number of limiting shafts 303 and the distribution of the limiting shafts 303 in the mounting holes 302 to adapt to different numbers of types of gaskets 10 and connecting plates 20, thereby increasing the scope of application.

[0021] The limiting shaft 303 has a stepped cylindrical structure. The raised portion of the limiting shaft 303 is a cylinder with a diameter of 17.5 mm and an M12 thread at the bottom. This size is the preferred size for use in this application to provide a connection effect between the limiting shaft 303 and the welding disk 301, while also being able to fit with the gasket 10 and the connecting plate 20 in a clearance manner.

[0022] When the utility model is used, the limiting shaft 303 is plugged into or threadedly fixed with the welding disk 301, and then the limiting hole 202 on the plate body 201 is inserted into the outside of the limiting shaft 303, and then the ring body 101 is inserted into the outside of the limiting shaft 303, and the ring body 101 and the plate body 201 are in contact with each other. At this time, the position between the ring body 101 and the plate body 201 has been positioned, and the subsequent welding operation can be carried out to avoid the occurrence of offset holes after subsequent welding, which affects the threading operation.

[0023] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
