Description

Technical Field

[0001] This utility model relates to the field of loading tooling technology, specifically a loading tooling that can reduce deformation of plate products. Background Technology

[0002] Currently, medium carbon alloy steel plate products are prone to warping deformation after conventional quenching. The larger the product diameter, the more obvious the deformation, which can easily make subsequent precision machining impossible, seriously affecting the product's performance and service life. Therefore, loading fixtures are needed to limit the workpiece.

[0003] Existing loading fixtures limit the movement of workpieces by setting two sets of channel steels on the curved surfaces on both sides of the bottom of the workpiece to prevent the workpiece from rotating. However, due to the limited height of the channel steels, when the fixture is moved and is hit, causing it to shake, the workpiece is prone to come off between the two sets of channel steels, resulting in damage to the workpiece. Utility Model Content

[0004] The purpose of this utility model is to provide a loading fixture that can reduce deformation of plate products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a loading fixture that can reduce deformation of plate products, comprising a base and round steel. Multiple sets of supports are fixedly connected to the top of the base. A fixture base plate is connected through the outer side of each support. A positioning channel steel is provided on the top of the fixture base plate. A fixture top plate is provided on the top of the positioning channel steel. A fixing mechanism is provided inside the positioning channel steel. A workpiece is placed between the fixture base plate and the fixture top plate. Multiple sets of through holes are opened inside both the fixture base plate and the fixture top plate, and the through holes are hexagonal in shape. Round steel is connected through the interior of both the fixture base plate and the fixture top plate. Nuts a are threaded to both ends of the round steel. An unfolding limiting mechanism is provided on one side of the positioning channel steel.

[0006] Preferably, the fixing mechanism includes a bolt, which is connected through the positioning channel steel and the tooling base plate, and the top of the bolt is threaded with a nut b.

[0007] Preferably, the unfolding limiting mechanism includes a connecting block, which is disposed on one side of the positioning channel steel. A worm gear is rotatably connected inside the connecting block via a bearing. A worm wheel is meshed with the outside of the worm gear. Connecting frames are welded and fixed on both sides of the worm wheel. The two sides of the connecting frames are rotatably connected to the connecting block via rotating shafts. A limiting frame is welded and fixed at one end of the connecting frame. An unfolding mechanism is disposed inside the limiting frame. An adjustment mechanism is disposed on one side of the connecting block.

[0008] Preferably, the adjusting mechanism includes a connecting shaft, which is fixedly connected to one side of the connecting block. The outer side of the connecting shaft is rotatably connected to the positioning channel steel via a bearing. A pin is slidably connected to one side of the positioning channel steel. A spring is sleeved on the outer side of the pin. One end of the spring abuts against the positioning channel steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This loading fixture, which can reduce the deformation of plate products, allows for further workpiece limiting when the angle of the connecting block is adjusted by rotation. Then, the worm gear can be rotated to mesh with the worm wheel, causing the worm wheel to drive the connecting frame to rotate. When one side of the connecting frame contacts the side of the workpiece, the threaded rod and threaded block can be rotated to perform threaded transmission, causing the threaded block to move upward. When the threaded block moves, it can drive the connecting rods on both sides to unfold, thereby pushing the two sets of rotating rods to rotate and unfold as well. The unfolded rotating rods can extend the support and limiting area of ​​the limiting frame, thereby limiting and protecting the workpieces in other positions in the loading fixture. Thus, the above operation facilitates the limiting and protection of the workpiece. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 The figure shows a loading fixture for reducing deformation of plate products, including a base 1 and round steel bars 8. Multiple sets of supports 2 are fixedly connected to the top of the base 1. A fixture base plate 3 is connected through the outer side of the supports 2. A positioning channel steel 4 is provided on the top of the fixture base plate 3, and a fixture top plate 6 is provided on the top of the positioning channel steel 4. A fixing mechanism is provided inside the positioning channel steel 4. A workpiece 5 is placed between the fixture base plate 3 and the fixture top plate 6. Multiple sets of through holes 7 are opened inside both the fixture base plate 3 and the fixture top plate 6, and the through holes 7 are hexagonal in shape. Round steel bars 8 are connected through the interior of both the fixture base plate 3 and the fixture top plate 6. Nuts a9 are threaded to both ends of the round steel bars 8. An unfolding limiting mechanism is provided on one side of the positioning channel steel 4. Specifically, when the multiple sets of round steel bars 8 are close to the workpiece 5, they can limit and protect the workpiece 5, preventing deformation of the workpiece 5 during quenching.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The fixing mechanism shown in the figure includes a bolt 10, which is connected through the positioning channel steel 4 and the tooling base plate 3. The top of the bolt 10 is threaded with a nut b11, and the nut b11 and the bolt 10 form a threaded transmission structure.

[0021] Please see Figure 2 , Figure 3 and Figure 5The diagram shows that the unfolding limiting mechanism includes a connecting block 12, which is located on one side of the positioning channel steel 4. A worm gear 16 is rotatably connected to the inside of the connecting block 12 via bearings. A worm wheel 17 is meshed with the outside of the worm gear 16. Connecting frames 18 are welded and fixed to both sides of the worm wheel 17. The two sides of the connecting frame 18 are rotatably connected to the connecting block 12 via rotating shafts. A limiting frame 19 is welded and fixed to one end of the connecting frame 18. An unfolding mechanism is installed inside the limiting frame 19. An adjustment mechanism is installed on one side of the connecting block 12. The worm wheel 17 and the worm gear 16 form a meshing transmission structure. Specifically, due to the irreversible rotation characteristics of the worm wheel 17 and the worm gear 16, the worm wheel 17 cannot rotate unless the worm gear 16 rotates. Therefore, the angle of the connecting frame 18 will be fixed after adjustment.

[0022] Please see Figure 3 and Figure 5 The adjustment mechanism shown in the figure includes a connecting shaft 13, which is fixedly connected to one side of the connecting block 12. The outer side of the connecting shaft 13 is rotatably connected to the positioning channel steel 4 through a bearing. A pin 14 is slidably connected to one side of the positioning channel steel 4. A spring 15 is sleeved on the outer side of the pin 14. One end of the spring 15 abuts against the positioning channel steel 4. Two sets of slots matching the pin 14 are opened on the outer side of the connecting shaft 13. The pin 14 and the positioning channel steel 4 form a sliding structure. The angle between the two sets of slots on the outer side of the connecting shaft 13 is ninety degrees, which can complete the ninety-degree adjustment of the connecting block 12.

[0023] Please see Figure 3 and Figure 4 The unfolding mechanism shown in the figure includes a threaded rod 20, and a threaded block 21 is threadedly connected to the outer side of the threaded rod 20. Both sides of the threaded block 21 are rotatably connected to connecting rods 22 via rotating shafts. The threaded rod 20 and the threaded block 21 constitute a threaded transmission structure.

[0024] Please see Figure 3 and Figure 4 In the figure, one end of the connecting rod 22 is rotatably connected to the rotating rod 23 via a rotating shaft. One end of the rotating rod 23 is movably connected to the limiting frame 19 via a hinge. The limiting frame 19 and the rotating rod 23 form a rotating structure.

[0025] Working principle: This loading fixture, which reduces deformation of plate products, fixes workpiece 5 by feeding workpiece 5 between fixture base plate 3 and fixture top plate 6, then placing two sets of positioning channel steel 4 at the bottom of workpiece 5 so that the edges of the positioning channel steel 4 contact the edges of workpiece 5 to prevent workpiece 5 from rolling, and then inserting four sets of round steel 8 through through holes 7 through fixture base plate 3 and fixture top plate 6 into both sides of workpiece 5, and rotating nuts a9 at both ends of round steel 8 to fix round steel 8, keeping the product vertical and preventing it from moving back and forth. At the same time, round steel 8 can protect workpiece 5 from deformation and prevent workpiece 5 from deforming during processing.

[0026] When further limiting the workpiece 5 is required, the spring 15 is compressed by pulling the pin 14. After the pin 14 disengages from the outer slot of the connecting shaft 13, the connecting block 12 can be rotated 90 degrees. After rotation, the pin 14 is released, and the spring 15 pushes the pin 14 to move and engage with the connecting shaft 13, thus limiting and fixing the connecting shaft 13 and the connecting block 12. Then, the worm gear 16 can be rotated to mesh with the worm wheel 17, causing the worm wheel 17 to drive the connecting frame 18 to rotate. When one side of the connecting frame 18 contacts the side of the workpiece 5, the threaded rod 2 can be rotated. The threaded block 21 is driven by the threaded block 21, causing the threaded block 21 to move upward. When the threaded block 21 moves, it can drive the connecting rods 22 on both sides to unfold, thereby pushing the two sets of rotating rods 23 to rotate and unfold as well. The unfolded rotating rods 23 can extend the support and limiting area of ​​the limiting frame 19, thereby limiting and protecting the workpiece 5 in other positions in the loading fixture. Since the limiting height of the limiting frame 19 for the workpiece 5 is much higher than that of the positioning channel steel 4, it can prevent the workpiece 5 from shaking and falling off the positioning channel steel 4. In this way, the workpiece 5 can be easily limited and protected through the above operation.

[0027] It should be noted that by rotating the angle of the adjusting connecting block 12, the worm gear 16 can be rotated to mesh with the worm wheel 17, so that the worm wheel 17 drives the connecting frame 18 to rotate. When one side of the connecting frame 18 contacts the side of the workpiece 5, the threaded rod 20 can be rotated to perform threaded transmission with the threaded block 21, so that the threaded block 21 moves upward. When the threaded block 21 moves, it can drive the connecting rods 22 on both sides to unfold, thereby pushing the two sets of rotating rods 23 to rotate and unfold as well. The unfolded rotating rods 23 can extend the support and limiting area of ​​the limiting frame 19, thereby limiting and protecting the workpiece 5 in other positions in the loading fixture.
