Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe processing, in particular to a fixing device for pipe welding. Background Art
[0002] The welding process of pipes generally only uses different welding methods. Plastic pipe welding generally uses hot melt welding, and metal pipe welding uses gas shielded welding such as argon arc welding. However, no matter which welding method is used, when welding metal pipes or plastic pipes, it is generally necessary to clamp and position the two sections of pipes first, and then butt the pipe ends together for welding. However, in actual use, there are many types of pipes. When encountering pipes with bends, the existing devices are difficult to adjust according to the style of the pipes. At this time, manual auxiliary fixation is required. However, manual auxiliary fixation has certain disadvantages. The pipe will shake during auxiliary fixation, which will affect the welding quality. Utility Model Content

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

It should be noted that the double-headed threaded rod 4 can be driven to rotate by the motor 2, thereby driving the slider 5 threadedly connected to the double-headed threaded rod 4 to move.
[0022] The upper end surface of each slider 5 is fixedly installed with a working box 6, each working box 6 is provided with a limit device, each working box 6 is provided with an adjustment device, and the output end of the limit device is against the output end of the adjustment device, the output shaft of each adjustment device passes through the top wall of the working box 6 and extends to be installed with a first mounting block 7, the upper end surface of each first mounting block 7 is fixedly installed with a fixing assembly, each fixing assembly includes a first fixing block 8 and a second fixing block 9, and the first fixing block 8 and the second fixing block 9 are fixedly installed on the first mounting block 7. On the upper end surface, one side of the first fixed block 8 is connected to the first annular plate 10 through two connecting plates, and the bottom end of the first annular plate 10 contacts the upper end surface of the first mounting block 7, and the second fixed block 9 is threadedly connected to the screw 19, one end of the screw 19 is connected to the second annular plate 20 through a bearing, and the bottom end of the second annular plate 20 contacts the upper end surface of the first mounting block 7. It should be noted that: by the second annular plate 20 contacting the upper end surface of the first mounting block 7, the second annular plate 20 will not rotate when being driven by the screw 19.
[0023] Each limiting device includes a connecting column 14, and the connecting column 14 is fixedly installed on the bottom wall of the working box 6. A second mounting block 15 is fixedly installed on the upper end surface of the connecting column 14. A limiting groove 18 is opened on one side of the second mounting block 15. Two springs 17 are fixedly connected in the limiting groove 18. One end of the two springs 17 is commonly connected to the limiting block 16, and the limiting block 16 is slidably clamped in the limiting groove 18, and one end of the limiting block 16 is against the output end of the adjusting device. One side of each limiting block 16 is tilted. It should be noted that: the one side tilting setting of the limiting block 16 can ensure that the tooth block of the first gear 11 can continue to rotate through the inclined surface of the limiting block 16.
[0024] Each adjusting device includes a first rotating shaft 12 and a second rotating shaft 13, and the first rotating shaft 12 is rotatably installed on the top wall of the working box body 6, and the second rotating shaft 13 is rotatably installed on the bottom wall of the working box body 6, and one end of the second rotating shaft 13 passes through the top wall of the working box body 6 and is fixedly connected to the first mounting block 7, and one end of the first rotating shaft 12 away from the top wall of the working box body 6 passes through the working box body 6 and extends to be installed with a rotating handle, a second gear 21 is installed on the outer wall of the first rotating shaft 12, and a first gear 11 is installed on the outer wall of the second rotating shaft 13, and the second gear 21 is meshed with the first gear 11. It should be noted that the first gear 11 can be driven to rotate by rotating the second gear 21.
[0025] Before use, the utility model is firstly placed in a fixed assembly with two pipes to be welded, and then the screw 19 is turned, and the screw 19 drives the second annular plate 20 to move. At this time, the inner wall of the second annular plate 20 will contact the pipe until the pipe abuts against the inner wall of the first annular plate 10, and the fixation of the pipe is completed.
[0026] If you need to adjust the angle of the fixed component, you can turn the handle to drive the first shaft 12 to rotate, and the second gear 21 rotates synchronously. At this time, the rotation of the second gear 21 will drive the first gear 11 meshing with it to rotate synchronously. At the same time, the rotation of the first gear 11 will drive the second shaft 13 to rotate. At this time, the first mounting block 7 fixedly installed on the upper end surface of the second shaft 13 will rotate, and the adjustment of the fixed component is completed.
[0027] When the first gear 11 rotates, the limit block 16 of the limit device will contact the tooth block of the first gear 11. Because one side of the limit block 16 is tilted, when the tooth block of the first gear 11 contacts the tilted side of the limit block 16, the tooth block can continue to move on its tilted surface. At the same time, the movement of the tooth block will compress the two springs 17 through the limit block 16. At this time, the limit block 16 will slide in the limit groove 18. When the first gear 11 rotates, the limit block 16 will, according to the elastic characteristics of the two springs 17, make the end face of the limit block 16 against the tooth groove of the first gear 11. Because the limit block 16 has only one side tilted, if the first mounting block 7 causes the first gear 11 to reverse due to accidental contact or other reasons, the tooth block of the first gear 11 will contact the surface of the limit block 16 that is not tilted, and the limit block 16 will limit the first gear 11.
[0028] After completing the fixing and adjustment of the pipe, the motor 2 can be started, and the output shaft of the motor 2 drives the double-headed threaded rod 4 to rotate. At this time, the two sliders 5 threadedly connected to the double-headed threaded rod 4 will approach each other. At this time, the distance between the two pipes can be adjusted according to the actual welding distance.
[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
