Description

Technical Field

[0001] The invention relates to the technical field of pipe joint processing equipment, in particular to a device capable of processing a welding joint arc. Background Art

[0002] In various mechanical hydraulic systems, steel pipe assemblies of different diameters often require welding some branch joints in the middle of the steel pipe. To avoid splashing into the inner cavity of the steel pipe during welding, the welding end of the welded joint needs to be designed into an arc with the same diameter as the steel pipe to achieve seamless welding with the steel pipe assembly. Figure 1 It is a structural diagram of a welding joint. The welding end 2 of the welding joint 1 is in an arc shape. The arc of the welding joint 1 is often processed by using a milling cutter on a milling machine, which is very inefficient and costly. Summary of the Invention

To this end, the present invention provides a device for processing a circular arc of a welded joint, which can improve the processing efficiency of the circular arc at the welding end of the welded joint and reduce production costs.

[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] Reference Figures 2 to 5 As shown, the device for processing the arc of a welding joint of the present invention includes: a cylindrical lathe clip, the lathe clip includes an integral clamp body 110 and an elastic clamp 120, an axial hole 200 is axially provided in the elastic clamp 120, the elastic clamp 120 includes a plurality of elastic clamping plates 121, and the elastic clamp 120 is radially provided with at least one stepped hole, the stepped hole is communicated with the axial hole 200, and the stepped hole is provided at the joint between adjacent elastic clamping plates 121.

[0024] The lathe clip is fixed on the CNC lathe. When processing the weld joint 1, the weld joint 1 is placed in the stepped hole, wherein the welding end face of the weld joint 1 extends into the axial hole 200, and the frustum of the weld joint 1 and the stepped surface of the stepped hole complete the positioning. After the weld joint 1 is installed, the elastic collet shrinks, and the elastic clamping plates 121 close together, clamping the weld joint 1 in the stepped hole. Subsequently, the boring tool of the CNC lathe extends into the elastic collet 120 along the axial hole 200. When the boring tool passes through the end face of the weld joint 1, the arc processing of the welding end of each weld joint 1 can be completed at one time.

[0025] Because the stepped holes are provided at the joints of the elastic clamping plates 121, when adjacent elastic clamping plates 121 are brought together, the stepped holes close together. Therefore, the number of stepped holes can be increased or decreased based on the number of elastic clamping plates 121. As the number of elastic clamping plates 121 increases, the number of stepped holes can also increase. Therefore, multiple welded joints 1 can be processed at once as needed, improving processing efficiency.

[0026] In some embodiments of the present invention, there are two elastic splints 121 , which are symmetrically arranged up and down. There are two step holes arranged on the elastic clamp 120 , which are respectively arranged at the joints on both sides of the two elastic splints 121 .

[0027] The two elastic clamps 121 are symmetrically arranged up and down, which is a basic structure of the present invention. The two elastic clamps 121 are symmetrically arranged up and down, so that the step holes can be arranged on both sides of the elastic clamp 120, and the welding joint 1 can be installed in the step holes on both sides.

[0028] When the welding joint 1 is installed into the step hole, since the elastic clamp 120 is composed of multiple elastic clamping plates 121, its special structure causes the welding joint 1 to easily fall out of the step hole when it is installed into the step hole and before the elastic clamp 120 is clamped. Therefore, when the welding joint 1 is installed into the step hole, the welding joint 1 can be supported by hand to prevent it from falling out of the step hole, and then released after the elastic clamp 120 is clamped.

[0029] In some embodiments of the present invention, there are four elastic clamps 121 , and three step holes are provided on the elastic clamp 120 , which are respectively provided at the top and the joints of the two sides of the elastic clamp 121 .

[0030] The preferred embodiment of the present invention employs four elastic clamps 121, which allow for the provision of three stepped holes, allowing the simultaneous processing of three welded joints 1. The welded joint 1 installed in the top stepped hole can be stably secured without external force, while the welded joints 1 installed in the side stepped holes can be stabilized by a worker's hands. No stepped holes are provided at the bottom, as such would make it difficult to insert a welded joint 1.

[0031] It should be noted that only two specific implementations are given in this embodiment. In actual practice, the number of step holes can be increased or decreased according to the adjustment of the elastic clamping plate 121. The elastic clamping plate 121 can be provided in different implementations such as three or five pieces.
