Description
Technical Field
[0001] The utility model belongs to the field of fixture equipment, and particularly relates to a welding fixture convenient for pipeline installation. Background Art
[0002] During welding, in order to avoid welding deformation and dislocation of the welded parts, ensure the dimensions of the welded parts, improve the assembly accuracy and efficiency, fixtures are usually used to clamp and fix the welded parts to facilitate welding. The firmness of the fixation of the welded parts is directly related to the welding quality. Moreover, when welding pipelines, fixtures are more needed for clamping and fixing. Due to the smooth surface of the round pipe, the clamping effect is poor. When fixing the round pipe, the round pipe is very likely to shift in position during welding after clamping. And when butt-welding two welded parts, the current fixtures cannot adjust the angle after fixing the two welded parts, and the functions are relatively single. Summary of the Utility Model
[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a welding fixture convenient for pipeline installation, effectively solving the problems mentioned in the above background art.
[0004] The technical solution adopted by the utility model to solve the above problems is as follows:
[0005] A welding fixture convenient for pipeline installation includes a support plate. The left and right sides of the upper end of the support plate are respectively hinged with swing plates. One fixed plate is fixedly connected to the ends of the two swing plates far away from the support plate. A pressing plate is arranged on the upper side of the fixed plate. A guide rail is fixedly connected to the corresponding end of the pressing plate and the fixed plate. A chute is opened on the surface of the swing plate along the length direction. The guide rail is slidably connected to the inner side of the chute. Adjusting screws are respectively rotatably connected to the surface of the swing plate along the length direction.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the accompanying drawings. However, the present utility model is not limited to these embodiments.
[0020] As Figures 1-4 shown, the utility model provides a welding fixture convenient for pipeline installation, including a support plate 15. The left and right sides of the upper end of the support plate 15 are respectively hinged with swing plates 7. One end of the two swing plates 7 far away from the support plate 15 is fixedly connected with a fixing plate 8. An upper side of the fixing plate 8 is provided with a pressing plate 9. One end of the pressing plate 9 corresponding to the fixing plate 8 is fixedly connected with a guide rail 10. A chute 13 is opened on the surface of the swing plate 7 along the length direction. The guide rail 10 is slidably connected inside the chute 13. The surface of the swing plate 7 is respectively rotatably connected with adjusting screws 11 along the length direction. The adjusting screws 11 are threadedly connected with the guide rail 10. The lower ends of the adjusting screws 11 are respectively fixedly connected with adjusting knobs 12.
[0021] When in use, the pipeline can be placed between the pressing plate 9 and the fixing plate 8. By rotating the adjusting knob 12 to drive the adjusting screw 11 to rotate, and then under the action of the threaded connection between the adjusting screw 11 and the guide rail 10, the guide rail 10 can be driven to move inside the chute 13. When the pressing plate 9 is driven to move towards the fixing plate 8 by rotating the adjusting knob 12, the pipeline inside can be clamped and fixed. Then, by controlling the swinging of the two swing plates 7, the docking angle of the two pipelines can be adjusted, which is convenient for welding the two pipelines. When in use, the angles of the two pipelines can be adjusted according to needs, and the applicable range is wide.
[0022] One side of the fixing plate 8 corresponding to the pressing plate 9 is respectively provided with arc-shaped grooves 16, which can cooperate with round pipes and are convenient for fixing round pipes. The flat surfaces on both sides of the arc-shaped grooves 16 can cooperate with square pipes for fixing, improving the applicable range of the device and the fixing firmness, and improving the welding effect.
[0023] Elastic rubber pads are respectively fixedly connected to the surfaces of the arc-shaped grooves 16, which can improve the fixing effect on the round pipes and prevent the round pipes from sliding inside the arc-shaped grooves 16.
[0024] A bottom plate 1 is fixedly connected to the bottom of the support plate 15. The left and right sides of the front and rear ends of the bottom plate 1 are respectively fixedly connected with legs 14, which are used to conveniently support the device and are convenient for users to use.
[0025] On the upper end of the bottom plate 1, support sliding grooves 2 are respectively formed along the length direction on the left and right sides. A support sliding block 3 is slidably connected inside the support sliding groove 2. The upper ends of the support sliding blocks 3 are respectively hinged with hinge rods 6. The other ends of the hinge rods 6 are respectively hinged with the surfaces of the corresponding swing plates 7. When the two swing plates 7 swing to adjust the angle, under the action of the hinge rods 6 driving the support sliding blocks 3 to slide inside the support sliding grooves 2, the stability of the two swing plates 7 during swinging can be improved, avoiding gaps in the connection between the two swing plates 7 and the support plate 15, resulting in shaking between the two swing plates 7 during use and affecting the welding quality of the steel pipes.
[0026] The support sliding blocks 3 on the left and right sides are commonly threadedly connected with a double-threaded screw rod 4. On both sides of the surface of the double-threaded screw rod 4, thread portions with opposite thread directions are respectively formed. The support sliding blocks 3 are respectively threadedly connected with the corresponding thread portions. The right end of the double-threaded screw rod 4 is fixedly connected with a handle 5. By rotating the handle 5, the double-threaded screw rod 4 can be driven to rotate. Under the action of the double-threaded screw rod 4 being threadedly connected with the two support sliding blocks 3, the support sliding blocks 3 can be driven to move relatively. Furthermore, under the transmission of the hinge rods 6, the two swing plates 7 can be driven to swing synchronously and relatively, facilitating the user to adjust the angle of the swing plates 7 and facilitating the user's use; the handle 5 has a circular plate structure, and a grip rod 17 is rotatably connected to a non-central position of the handle 5 for facilitating the user to rotate the handle 5 and facilitating the user to use this device.
