However, since the conical column will contact the end of the U-shaped tube, when fixing the U-shaped tube and then detecting the strength of the U-shaped tube through the detection mechanism, the part of the U-shaped tube in contact with the conical column may be worn, thereby reducing the protection effect on the U-shaped tube, and may cause damage to the U-shaped tube port. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a fixing tooling for U-shaped tube strength detection to solve the technical problem that when fixing the U-shaped tube through a conical column, it may cause wear to the U-shaped tube port and thus reduce the protection effect on the U-shaped tube.

[0008] By adopting the above technical scheme, when the slide seat moves towards the spring, it will squeeze the spring, causing the spring to be compressed under force.

[0009] Further, the adjusting assembly further includes guide holes formed at the top and bottom of the insertion rod, a guide rod is inserted into the interior of the guide holes, and the end of the guide rod is connected to the support plate.

[0010] By adopting the above technical solution, when the support plate moves, it will drive the guide rod to move in the guide hole, and the arrangement of the guide rod and the guide hole can guide the support plate.

[0011] Further, a side plate is fixed to one side of the top of the bottom plate, a clamping seat is installed on one side of the side plate, and a clamping groove is formed on one side of the clamping seat.

[0012] By adopting the above technical solution, the arrangement of the clamping seat and the clamping groove facilitates the insertion of one end of the U-shaped tube and is convenient for limiting the U-shaped tube.

[0013] Further, a fixing plate is provided on the other side of the top of the bottom plate, a hydraulic cylinder is installed on one side of the fixing plate, and an adjusting seat is installed at the output end of the hydraulic cylinder through a piston rod.

[0026] In the present utility model, by providing an adjusting assembly, after the insertion rod is inserted into the U-shaped tube, the user can rotate the threaded shaft, causing the threaded shaft to move downward and drive the pressing block to move downward. The pressing plate then pushes the movable block to move, and the movable block drives the sliding seat to move. The sliding seat squeezes the spring and pushes the push plate to rotate, and the push plate then pushes the support plate to move, so that the support plate is in contact with the inner wall of the U-shaped tube. After the contact, stop rotating the threaded shaft. At this time, the U-shaped tube can be limited by the support plate and the purpose of fixing the U-shaped tube can be achieved. When fixing U-shaped tubes of the same inner diameter batch, there is no need to adjust the position of the support plate. Just make the support plate move into the U-shaped tube along with the insertion rod to limit the U-shaped tube. And when it is necessary to fix U-shaped tubes with different inner diameters, just rotate the threaded shaft to make the pressing block move, and the position of the support plate can be adjusted to adapt to U-shaped tubes with different inner diameters, thereby improving the applicability of this fixing tooling. There is no need to replace the fixing structure, and at the same time, when using a conical column to clamp the U-shaped tube, the situation that the end position of the U-shaped tube is worn by the conical column can be avoided, thereby improving the protection effect on the U-shaped tube.

[0036] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0037] Embodiment 1:

[0038] A fixing tool for detecting the strength of a U-shaped tube, as Figures 1 - 7 shown, includes a bottom plate 1 and an inserting rod 16. An adjusting component 9 is provided on the inserting rod 16. One side of the top of the bottom plate 1 is fixedly provided with a side plate 2. A card seat 3 is installed on one side of the side plate 2. A card slot 4 is opened on one side of the card seat 3. Rubber pads 5 are installed above and below the inside of the card slot 4. The settings of the card seat 3 and the card slot 4 facilitate the insertion of one end of the U-shaped tube 6 and facilitate the positioning of the U-shaped tube 6. On the other side of the top of the bottom plate 1, there is a fixed plate 14. A hydraulic cylinder 15 is installed on one side of the fixed plate 14. The output end of the hydraulic cylinder 15 is installed with an adjusting seat 17 through a piston rod. When it is necessary to move the adjusting seat 17, the hydraulic cylinder 15 can be started, so that the piston rod extends, thereby driving the adjusting seat 17 to move, so as to adjust the position of the adjusting seat 17. A groove 11 is opened on one side of the adjusting seat 17, and a bidirectional lead screw 13 is connected to the inside of the groove 11 through a bearing. Two movable seats 12 are sleeved on the outer wall of the bidirectional lead screw 13. After the bidirectional lead screw 13 rotates, it will drive the movable seats 12 to move. The outer wall of the movable seat 12 fits with the inner wall of the groove 11 to prevent the movable seat 12 from rotating.

[0039] Refer to Figures 1 - 5, one end of the bidirectional lead screw 13 penetrates to the outside of the adjusting seat 17 and is connected with a turntable 10. The movable seat 12 is threadedly connected to the bidirectional lead screw 13. When the bidirectional lead screw 13 rotates, it will drive the two movable seats 12 to move simultaneously. The movable seat 12 will drive the insertion rod 16 to move. One side of the movable seat 12 is provided with an insertion rod 16. A U-shaped tube 6 is inserted into the inner part of the clamping groove 4. After the insertion rod 16 is inserted into the inner part of the U-shaped tube 6, the U-shaped tube 6 can be limited. One end of the insertion rod 16 is located in the inner part of the U-shaped tube 6. The support plate 907 is attached to the inner wall of the U-shaped tube 6. The support plate 907 can limit the U-shaped tube 6 to prevent the U-shaped tube 6 from moving randomly. A retaining disk 18 is further provided on the outer wall of the insertion rod 16, and one end of the retaining disk 18 is attached to the end of the U-shaped tube 6. The retaining disk 18 can cooperate with the support plate 907 to fix the U-shaped tube 6.

[0040] Specifically, the adjusting assembly 9 includes a cavity 902 opened in the insertion rod 16, a threaded shaft 901 threadedly connected to the insertion rod 16, and a through port 910 opened on the outer wall of the insertion rod 16. A movable block 904 is slidably connected to the inner part of the cavity 902. A slide rod 906 is fixed to one side of the inner part of the cavity 902, and a slide seat 905 is sleeved on the outer wall of the slide rod 906. A connecting rod is connected between the slide seat 905 and the movable block 904. The top end of the threaded shaft 901 is connected with a knob. A limiting groove is opened on the other side of the inner part of the cavity 902, and a limiting block is arranged in the limiting groove. The limiting block is connected to one side of the pressing block 903, which is convenient for the user to rotate the threaded shaft 901 through the knob, so that the threaded shaft 901 moves. At the same time, the movement of the pressing block 903 will drive the limiting block to slide in the limiting groove, thereby improving the stability of the pressing block 903 when it moves and preventing the pressing block 903 from rotating.

[0041] Specifically, push plates 909 are connected to the top and bottom of the slide seat 905 through rotating shafts, and a support plate 907 is connected to the push plates 909 through rotating shafts. The surface of the support plate 907 in contact with the U-shaped tube 6 is provided with an anti-slip pad. The bottom end of the threaded shaft 901 is connected with a pressing block 903 through a bearing. When it is necessary to adjust the position of the support plate 907, the user can rotate the threaded shaft 901 so that the threaded shaft 901 moves downward and drives the pressing block 903 to move downward. The pressing block 903 then pushes the movable block 904 to move. A spring 908 is arranged between one side of the slide seat 905 and the inner wall of the cavity 902, and the spring 908 is sleeved on the outer wall of the slide rod 906. One side of the pressing block 903 and one side of the movable block 904 are both arranged in an inclined plane. One side of the pressing block 903 is in contact with one side of the movable block 904. The slide seat 905 is slidably connected to the slide rod 906. When the slide seat 905 moves towards the spring 908, it will squeeze the spring 908, causing the spring 908 to be compressed under force.

[0042] Embodiment Two:

[0043] Based on the above-mentioned first embodiment, since the rotation of the push plate 909 will push the support plate 907 to move, in order to prevent the support plate 907 from tilting and improve the stability of the support plate 907 when it moves, the following structure will be set up.

[0044] Specifically, the adjusting assembly 9 further includes guide holes 911 opened at the top and bottom of the insertion rod 16. A guide rod 912 is inserted into the interior of the guide holes 911, and the end of the guide rod 912 is connected to the support plate 907. When the support plate 907 moves, it will drive the guide rod 912 to move within the guide holes 911, and the arrangement of the guide rod 912 and the guide holes 911 can guide the support plate 907.

[0045] Embodiment Three:

[0046] Based on the above-mentioned first embodiment, in order to improve the stability of the adjusting seat 17 when it moves, the following structure will be set up.

[0047] Refer to Figures 1 - 3 , a chute 7 is further opened at the top of the bottom plate 1. A sliding plate 8 is arranged inside the chute 7, and the top of the sliding plate 8 is connected to the bottom of the adjusting seat 17. The adjusting seat 17 is slidably connected to the chute 7 through the sliding plate 8. When the adjusting seat 17 moves, it will drive the sliding plate 8 to slide inside the chute 7, thereby improving the stability of the adjusting seat 17 when it moves.

[0048] The working principle of the present utility model is as follows: First, the staff can install the tooling and connect it to the power supply. Then, one side of the U-shaped tube is clamped inside the card slot 4, and the two ends of the U-shaped tube 6 are placed towards the adjusting seat 17. Then, the bidirectional lead screw 13 is rotated through the turntable 10, so that one end of the two movable seats 12 is driven, and one end of the insertion rod 16 is driven. The insertion rod 16 drives the adjusting assembly 9 to move. When the two insertion rods 16 move to correspond to the two ends of the U-shaped tube 6, the staff stops rotating the turntable 10. At this time, the hydraulic cylinder 15 is started, so that the piston rod extends, thereby driving the adjusting seat 17 to move. The adjusting seat 17 drives the insertion rod 16 to move, and the insertion rod 16 then moves into the U-shaped tube 6. When the retaining disc 18 fits against the end of the U-shaped tube 6, the hydraulic cylinder 15 is closed;

[0049] Next, the rotatable threaded shaft 901 can be rotated so that the threaded shaft 901 moves downward and drives the pressing block 903 to move downward. The pressing block 903 then pushes the movable block 904 to move, and the movable block 904 drives the sliding seat 905 to move. The sliding seat 905 squeezes the spring 908 and pushes the push plate 909 to rotate. The push plate 909 then pushes the support plate 907 to move, so that the support plate 907 fits against the inner wall of the U-shaped tube 6. After the fitting, the threaded shaft 901 is no longer rotated. At this time, the U-shaped tube 6 can be limited by the support plate. When fixing the U-shaped tubes 6 of the same inner diameter batch, there is no need to adjust the position of the support plate 907. Just make the support plate 907 move into the U-shaped tube 6 following the insertion rod 16 to limit the U-shaped tube 6. When it is necessary to fix the U-shaped tubes 6 with different inner diameters, just rotate the threaded shaft 901 to move the pressing block 903, and repeat the above steps to adjust the position of the support plate 907 to adapt to the U-shaped tubes 6 with different inner diameters.
