Specific embodiments
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0028] Refer to Figures 1 - 6 , a bent pipe wire cutting fixture, including a mounting plate 1. The bottom of the mounting plate 1 is fixed on the workbench of the bent pipe wire cutting machine through legs 11, and the mounting plate 1 can be installed together with the bent pipe wire cutting machine, so that the cutting mechanism on the wire cutting machine can cut the bent pipe clamped on the mounting plate 1.
[0029] As Figure 1 shown, a through slot 5 is opened on one side of the top of the mounting plate 1. Connecting blocks 8 are installed inside the through slot 5 and on the top of the mounting plate 1. One end of the connecting block 8 located in the through slot 5 is installed with a threaded sleeve 6. One end of the through slot 5 is rotatably connected with a lead screw 4. One end of the lead screw 4 extends into the threaded sleeve 6 and is in threaded cooperation with the threaded sleeve 6. During actual use, the connecting block 8 located in the through slot 5 can be controlled to move along the through slot 5 by rotating the lead screw 4, so that the position between the two connecting blocks 8 can be adjusted according to the needs of the bent pipe size.
[0030] It should be noted that both sides of the connecting block 8 located in the through slot 5 are slidably connected to the guide rails fixed on both sides of the through slot 5 through sliders, so as to limit the connecting block 8 located in the through slot 5 and keep the connecting block 8 stable without shaking following the rotation of the lead screw 4.
[0031] As Figure 2 、 Figure 3 and Figure 6As shown, a rotating shaft 14 is rotatably connected to the top of the connecting block 8 located in the through groove 5. A first fixing plate 7 is fixedly installed at the top of the rotating shaft 14. During actual use, the rotating shaft 14 can be rotated to drive the first fixing plate 7 to rotate, so that the rotation angle of the first fixing plate 7 can be adjusted according to the bending angle of the bent pipe, and bent pipes with different bending angles can be adapted.
[0032] It should be noted that, as Figure 2 and Figure 3 shown, the bottom of the rotating shaft 14 extends below the connecting block 8, and a locking sleeve 13 is sleeved on the bottom of the rotating shaft 14. The locking sleeve 13 is in threaded cooperation with the rotating shaft 14. After adjusting the rotation angle of the first fixing plate 7, the staff fixes the first fixing plate 7 by hand, and then sleeves the locking sleeve 13 on the bottom of the rotating shaft 14 and tightens it, so that the top of the locking sleeve 13 tightly abuts against the bottom of the connecting block 8 to fix the rotating shaft 14, so that the first fixing plate 7 will not rotate by itself.
[0033] As Figure 1 shown, a second fixing plate 12 is installed on the top of the connecting block 8 installed on the top of the mounting plate 1. First clamping blocks 2 are installed on one side of the top of the first fixing plate 7 and the second fixing plate 12. Second clamping blocks 3 are provided on one side of the first clamping blocks 2. The first clamping blocks 2 and the second clamping blocks 3 are both arc-shaped, and a U-shaped space is formed between them. The bent pipe is placed in this space. During actual use, the two ends of the bent pipe to be cut can be placed between the corresponding first clamping blocks 2 and second clamping blocks 3, and the bent pipe can be clamped and fixed by the first clamping blocks 2 and the second clamping blocks 3.
[0034] As Figure 2 shown, guide rods 10 are symmetrically installed on one side of each first clamping block 2 close to the second clamping block 3. Each guide rod 10 passes through the corresponding second clamping block 3. First connecting rods 9 are provided between adjacent two guide rods 10. Both ends of each first connecting rod 9 are installed with annular sleeves 17 with an opening on one side. The annular sleeves 17 are sleeved on the corresponding guide rods 10. By moving the first connecting rod 9, the annular sleeve 17 can be driven to move towards the second clamping block 3, so that one end of the annular sleeve 17 abuts against the side surface of the second clamping block 3, so that the second clamping block 3 and the first clamping block 2 are fixed together, which is convenient for fixing.
[0035] As Figure 4 and Figure 5As shown, a connecting piece 15 is installed at the opening of each annular sleeve 17. Through holes 20 are formed in the sides of each pair of connecting pieces 15. A second connecting rod 22 is arranged inside the through holes 20. Both ends of the second connecting rod 22 extend to the outside of the through holes 20. One end of the second connecting rod 22 is connected with a limiting block 19. The diameter of the limiting block 19 is larger than the aperture of the through hole 20. A pressing handle 18 is arranged on the side of one of the pair of connecting pieces 15 that is far away from the limiting block 19. A receiving groove 16 is formed at the end of the pressing handle 18. One end of the second connecting rod 22 extends into the receiving groove 16 and is rotatably connected with the pressing handle 18 through a connecting shaft. The end of the pressing handle 18 abuts against the side of the connecting piece 15. During actual use, when one end of the annular sleeve 17 is pushed to abut against the side of the second clamping block 3, then the staff rotates the pressing handle 18. When the pressing handle 18 rotates, it will squeeze the connecting piece 15. Under the action of the limiting block 19 and the pressing handle 18, the annular sleeve 17 can be tightened, and the annular sleeve 17 can be firmly fixed on the guide rod 10, so that the second clamping block 3 can be fixed, and the fixing is convenient.
[0036] It should be noted that the annular sleeve 17 is made of elastic metal. In this way, when the pressing handle 18 is rotated, the annular sleeve 17 will be deformed and contracted under the extrusion of the pressing handle 18 and the limiting block 19.
[0037] Specifically, when clamping a bent pipe with the present utility model, the staff rotates the screw rod 4. Under the action of the threaded sleeve 6, the screw rod 4 drives the connecting block 8 located in the through groove 5 to move. After adjusting the connecting block 8 to a preset position, the first fixing plate 7 is rotated. Under the action of the rotating shaft 14, the first fixing plate 7 rotates to a preset angle. After the staff fixes the first fixing plate 7 by hand, the locking nut 13 at the bottom of the rotating shaft 14 is tightened to fix the rotating shaft 14, so that the positions of the first clamping block 2 and the second clamping block 3 on the first fixing plate 7 and the second fixing plate 12 match the shape of the bent pipe. Then, both ends of the bent pipe are placed between the corresponding first clamping block 2 and the second clamping block 3. Then, the second clamping block 3 is pushed so that the second clamping block 3 and the first clamping block 2 clamp the bent pipe. Then, the first connecting rod 9 is pushed so that the end of the annular sleeve 17 abuts against the side of the second clamping block 3. Then, the pressing handle 18 is rotated. When the pressing handle 18 rotates, it will synchronously squeeze the connecting piece 15 with the limiting block 19, so that the annular sleeve 17 is stressed and shrinks. The annular sleeve 17 is fixed on the guide rod 10. At the same time, the pressing handle 18 is stressed (as shown by the arrow direction in Figure 5 ) and will move in the rotating direction, so that the pressing handle 18 will not return to its original position by itself, and the fixing of the second clamping block 3 can be completed. Furthermore, the bent pipe is clamped and fixed by the first clamping block 2 and the second clamping block 3, and the fixing is convenient.
[0038] Furthermore, as Figure 1 and Figure 3As shown, the bottom end of the rotating shaft 14 is higher than the bottom end of the support leg 11. Under the action of the support leg 11, a space can be formed between the mounting plate 1 and the workbench of the wire cutting machine. The bottom of the rotating shaft 14 and the locking nut 13 are located in this space, which facilitates the adjustment of the locking nut 13 by the staff.
[0039] Furthermore, as Figure 6 shown, one end of the lead screw 4 extends to the outside of the mounting plate 1, and a rotating handle 21 is installed at the end of the lead screw 4. During actual use, the rotating handle 21 can reduce the rotation difficulty of the lead screw 4 and is convenient to use.
[0040] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
