Description

Technical Field

[0001] The utility model relates to a welding fixture which is easy to adjust the assembly size. Background Art

[0002] In some construction and production sites, some pipe fittings are often welded and fixed to each other. Welders usually splice the two pipe fittings where they need to be welded, and then weld and fix the spliced ​​parts. However, in this unassisted welding, the two pipe fittings are prone to shifting during the welding process. Furthermore, for some welding with size requirements, it is more likely to make mistakes, or the welding may not meet the use requirements. Utility Model Content

[0003] The purpose of the utility model is to overcome the above problems. We provide a welding fixture with easy-to-adjust assembly size, which can meet the welder's daily fixing work when welding pipe fittings.

[0004] To achieve the above-mentioned purpose, the utility model provides a welding fixture with easy adjustment of assembly size, which includes two fixture assemblies, and the two fixture assemblies are connected together by an elastic hinge. The two fixture assemblies can rotate relative to each other with the help of the elastic hinge. The fixture assembly includes a base plate, a fixed plate and a movable plate. The fixed plate is fixed to one end of the base plate, and a connecting plate is fixed to the other end of the base plate. A stud is screwed on the connecting plate, and the movable plate is fixed to one end of the stud relative to the fixed plate. The fixed plate, the movable plate and the connecting plate are all perpendicular to the base plate.

[0005] In one or more embodiments, two or more connecting plates are spaced apart on the bottom plate, and threaded holes for studs to be screwed are provided on all the connecting plates.

[0006] In one or more embodiments, a handle is provided on the other end of the stud relative to the movable plate.

[0007] In one or more embodiments, the fixing plate and the connecting plate are both welded and fixed to the bottom plate.

[0008] In one or more embodiments, the tension hinge includes a first connecting ear, a second connecting ear, a tension bolt and a nut. The first connecting ear and the second connecting ear are respectively fixed to the fixing plates of the two clamp assemblies. The first connecting ear and the second connecting ear are provided with through holes for the tension bolt to pass through, and the nut is threaded onto the tension bolt.

[0009] In one or more embodiments, a hand-tightening portion is provided on the nut.

[0010] In one or more embodiments, the thickness of the fixing plate, the bottom plate, and the connecting plate is 0.3CM-1CM.

[0011] Compared with the background technology, the utility model has the following effects: the welding fixture can fix two pipes that need to be welded and fixed, which is convenient for the welder to weld the splicing position, and the welding fixture can adjust the splicing position of the pipe fittings, making it easier for the welder to adjust the position before welding.

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] Please see Figure 1-2 The present application provides a welding fixture that is easy to adjust the assembly size, which includes two fixture assemblies 1, the two fixture assemblies are connected together by an elastic hinge 2, and the two fixture assemblies can rotate relative to each other with the help of the elastic hinge. The fixture assembly includes a base plate 3, a fixed plate 4 and a movable plate 5, the fixed plate is fixed to one end of the base plate, the other end of the base plate is fixed with a connecting plate 6, and the connecting plate is screwed with a stud 7, and the movable plate 5 is fixed to one end of the stud relative to the fixed plate 4. The fixed plate, the movable plate, and the connecting plate are all perpendicular to the base plate. The operator puts the pipe fitting between the fixed plate and the movable plate, and then rotates the stud to make the movable plate close to the fixed plate, thereby fixing the pipe fitting. After the pipe fittings on the two fixture assemblies are spliced ​​together by loosening the elastic hinge and rotating the fixture assembly, the elastic hinge is tightened, and then the splicing is welded. When using, the operator can adjust the splicing position of the two pipe fittings by adjusting the tightness of the fixture assembly.

[0016] Two or more connecting plates 6 are arranged at intervals on the bottom plate 3, and threaded holes for studs to be screwed are provided on all the connecting plates. Providing multiple connecting plates can strengthen the force so that the fixed plate and the movable plate can better clamp and fix the pipe fittings.

[0017] The other end of the stud 7 relative to the movable plate 5 is provided with a handle 8, and an operator can easily rotate the stud by means of the handle.

[0018] Preferably, the fixing plate 4 and the connecting plate 6 are both welded and fixed to the base plate 3, and the thickness of the fixing plate 4, the base plate 3 and the connecting plate 6 is 0.3CM-1CM, preferably 0.5CM and 0.8CM, which is selected according to actual needs.

[0019] The tension hinge comprises a first connecting ear 9, a second connecting ear 10, a tension bolt 11 and a nut 12. The first connecting ear and the second connecting ear are respectively welded and fixed to the fixing plates of the two clamp assemblies. The first connecting ear 9 and the second connecting ear 10 are provided with through holes for the tension bolt 11 to pass through. The nut is screwed onto the tension bolt. The two clamp assemblies are fixed by tightening the nut. The clamp assemblies are rotated by loosening the nut. A hand-tightening portion 121 is provided on the nut. With the help of the hand-tightening portion, the operator can directly manually rotate the nut to adjust the tightness.

[0020] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
