Detailed implementation mode

[0018] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0019] Embodiment:

[0020] As Figure 1 shown, a bracket welding and fixing device includes a workbench 1. Two guide rails 2 are slidably arranged on the workbench 1 and the two guide rails 2 are parallel to each other. Two chutes 18 are opened on the workbench 1. Two sliders 19 are fixedly arranged at the bottom of each guide rail 2 and the two sliders 19 are respectively slidably arranged in the two chutes 18. A third bolt 20 is threadedly connected to each slider 19 and the third bolt 20 abuts against the inner wall of the chute 18. The position of the guide rail 2 on the workbench 1 can be changed through the slider 19, and the moved slider 19 can be fixed through the third bolt 20.

[0021] As Figure 1 shown, a plurality of sliding blocks 3 are slidably arranged on the two guide rails 2. Connecting plates 21 are fixedly arranged on the plurality of sliding blocks 3. A fourth bolt 22 is threadedly connected to each of the plurality of connecting plates 21 and the fourth bolt 22 abuts against the side wall of the guide rail 2. The movement of the sliding block 3 can be realized through the guide rail 2, and the moved sliding block 3 can be fixed through the fourth bolt 22.

[0022] As Figure 1 and Figure 2 shown, clamping assemblies for horizontally clamping pipe fittings are arranged on opposite sides of the plurality of sliding blocks 3. The clamping assemblies include U-shaped connecting blocks 6, clamping plates 7 and screw rods 8. The connecting blocks 6 are fixedly arranged on one side of the sliding blocks 3. The clamping plates 7 are slidably arranged on the inner walls of the connecting blocks 6. The screw rods 8 are threadedly connected to the connecting blocks 6 and the ends of the screw rods 8 are rotatably connected to the clamping plates 7. The screw rods 8 are used to move the clamping plates 7 and make the clamping plates 7 abut against the inner walls of the connecting blocks 6. The clamping plates 7 can be driven to approach or move away from the pipe fittings through the screw rods 8, so as to realize the clamping of the pipe fittings. A groove for the sliding of the clamping plates 7 is arranged on one side of the connecting blocks 6.

[0023] As Figure 1 and Figure 2As shown, a clamping assembly for longitudinally clamping pipe fittings is provided on several sliding blocks 3. The clamping assembly includes a first rotating rod 9, a second rotating rod 10, an L-shaped mounting block 11, a first bolt 12, a nut 13, and a clamping block 14. The first rotating rod 9 is rotatably arranged on the top of the sliding block 3. The second rotating rod 10 is rotatably arranged on the top of the sliding block 3 and is parallel to the first rotating rod 9. The mounting block 11 is fixedly arranged on the first rotating rod 9, and a strip-shaped hole 15 is opened on the mounting block 11. The rotation of the mounting block 11 can be realized through the first rotating rod 9. The first bolt 12 is fixedly arranged on the second rotating rod 10 and the first bolt 12 slidably passes through the strip-shaped hole 15. The first bolt 12 on the first rotating rod 9 can rotate through the strip-shaped hole 15. The nut 13 is threadedly connected to the end of the first bolt 12 passing through the strip-shaped hole 15, and the nut 13 abuts against the top of the mounting block 11. The nut 13 can limit the rotated mounting block 11. The clamping block 14 is fixedly arranged at one end of the mounting block 11 away from the first rotating rod 9 and is used to abut against the top of the pipe fitting. The clamping block 14 can expand the clamping area of the pipe fitting.

[0024] As Figure 1 and Figure 3 shown, two through grooves 4 are opened on the workbench 1. A number of positioning columns 5 are slidably arranged in the two through grooves 4. A fixing assembly for fixing the position of the positioning column 5 in the through groove 4 is provided on each of the number of positioning columns 5. The fixing assembly includes a second bolt 16 and a fixing plate 17. The positioning column 5 is a circular ring column and a thread is provided on the inner wall of the positioning column 5. The second bolt 16 is threadedly connected to the inner wall of the positioning column 5. The fixing plate 17 is fixedly arranged at the end of the second bolt 16 and the fixing plate 17 abuts against the bottom surface of the workbench 1. The second bolt 16 can drive the fixing plate 17 to approach or move away from the bottom surface of the workbench 1, so as to control the movement of the positioning column 5.

[0025] As Figure 1 shown, two baffles 23 are slidably arranged between the two guide rails 2. Fifth bolts 24 are threadedly connected to the ends of the two baffles 23 and the fifth bolts 24 abut against the side walls of the guide rails 2. The baffles 23 are used for positioning the pipe fittings. By moving the baffles 23, a limiting effect can be exerted on the longitudinally placed pipe fittings.

[0026] Working principle:

[0027] First, the operator changes the position of the sliding block 3 according to the shape of the bracket and moves the sliding block 3 on the guide rail 2. After the sliding block 3 is moved in place, the operator tightens the fourth bolt 22 and makes the fourth bolt 22 abut against the side wall of the guide rail 2. Then, the operator places the pipe fitting in the concave groove of the connecting block 6. After that, the operator rotates the screw rod 8, and the screw rod 8 drives the clamping plate 7 to move and makes the clamping plate 7 abut against the pipe fitting, so as to clamp the pipe fitting between the connecting block 6 and the clamping plate 7. Then, the operator tightens the nut 13 on the first bolt 12. When the nut 13 rotates, it gradually approaches the mounting block 11. When the nut 13 abuts against the mounting block 11, the mounting block 11 can rotate on the sliding block 3 through the first rotating rod 9. When the mounting block 11 rotates, the first bolt 12 can move in the strip hole 15 on the mounting block 11, and the first bolt 12 can also rotate on the mounting block 11 through the second rotating rod 10. Thus, the clamping block 14 on the mounting block 11 gradually approaches the pipe fitting. Then, the user continues to rotate the nut 13 until the nut 13 completely abuts against the mounting block 11, so that the clamping block 14 on the mounting block 11 completely abuts against the pipe fitting, thereby restricting the position of the pipe fitting in the longitudinal direction.

[0028] Subsequently, the operator can change the position of the positioning column 5 on the workbench 1 through the second bolt 16 and place the pipe fitting to be welded between two adjacent positioning columns 5. Then, the operator tightens the second bolt 16, and the second bolt 16 drives the fixing plate 17 to abut against the bottom surface of the workbench 1, thereby restricting the position of the positioning column 5 and further restricting the position of the pipe fitting to be welded. Then, the operator can change the position of the baffle 23 through the fifth bolt 24 so that the baffle 23 abuts against the pipe fitting, thereby further restricting the position of the pipe fitting. Then, the operator can weld the pipe fitting through an external welding device.

[0029] When the operator needs to move the positions of the two guide rails 2, the operator can change the positions of the two guide rails 2 through the third bolt 20 and the slider 19, so as to adapt to the clamping of pipe fittings of different lengths.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
