Due to the inherent limitations of the casting process, various casting defects are inevitable, most of which affect strength and pose potential risks to valve use. During the ball valve manufacturing process, it is necessary to reinforce the valve body by welding.

[0003] Traditional welding reinforcement work uses fixtures for fixing accessories with poor adjustability, which cannot be freely adjusted in terms of orientation. This results in unsatisfactory welding reinforcement effects and substandard quality of the final product, necessitating the development of new fixtures. Utility Model Content

[0004] The purpose of this invention is to provide a welding reinforcement device for the valve body and housing of a ball valve, so as to solve the problems mentioned in the background art.

[0008] Preferably, the two-way screw 2 is symmetrically fitted with two movable rods on its outside, and a guide rod 2 passes through one side of each of the two movable rods, while a reinforcing plate is connected to the other side of each movable rod.

[0009] Preferably, a top plate is connected to the top of the front side of the device frame, a lifting cylinder is installed in the middle of the top plate, a welding assembly is installed at the bottom of the lifting cylinder, and a magnetic stone is connected to the front side of the top plate.

[0010] Preferably, the bottom of the base plate is connected to a base, and a limit block is connected inside the base by a spring. The top and bottom of the base are both connected to guide grooves that match the limit block.

[0011] Preferably, a protective baffle is hinged to the side of the limiting block away from the spring, and the outer end of the protective baffle extends to the front side of the base and is connected to an operating handle.

[0012] Preferably, a magnetic magnet is connected to the inner surface of the upper surface of the protective baffle, and the magnetic magnet is matched with a magnetic stone.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 An embodiment of this utility model is provided: a welding reinforcement device for the valve body and housing of a ball valve, including a device frame 1, a movable frame 4, a gear 18 and a gear 2 19. The bottom of the front side of the device frame 1 is connected to a base plate 5, and the top of the base plate 5 is symmetrically connected to a relief groove 14 that matches the movable frame 4.

[0025] The base plate 5 is internally connected to a bidirectional screw 12. A motor 15 is installed at one end of the bidirectional screw 12. The motor 15 and the bidirectional screw 12, together with the guide rod 11, enable the two moving frames 4 to move closer and further apart in a linear motion, which facilitates the adjustment of the spacing between the two reinforcing plates 9 according to the specifications of the workpiece.

[0026] The two ends of the bidirectional screw 12 are symmetrically fitted with movable frames 4. Guide rods 11 pass through the bottom of the two movable frames 4. The guide rods 11 are located at the bottom of the bidirectional screw 12. The two movable frames 4 are connected to gear 19 on the side that is relatively close to each other through rotating rod 3. Gear 18 is meshed on the top of gear 19. Motor 17 is connected to one side of gear 18 through driving rod 2. Through the arrangement of motor 17, driving rod 2, and gear 18, the rotating rod 3 and the connected gear 19 can be driven to rotate, so that the rotating frame 16 rotates as a whole. This facilitates the rotation of the fixed workpiece and makes it convenient to perform welding reinforcement operations on different positions of the workpiece.

[0027] Motor 2 17 is fixed to the side surface of the movable frame 4, and a rotating frame 16 is connected to one side of gear 2 19.

[0028] The rotating frame 16 is internally connected to a double-acting screw 29. Two movable rods 27 are symmetrically mounted on the outside of the double-acting screw 29. A guide rod 28 runs through one side of each movable rod 27, and a reinforcing plate 9 is connected to the other side of each movable rod 27. The top of the double-acting screw 29 extends to the top of the rotating frame 16 and is fitted with a rotating block 26. The arrangement of the rotating block 26 and the double-acting screw 29, in conjunction with the guiding nature of the guide rod 28, allows the two movable rods 27 to move linearly along the double-acting screw 29, moving away from and closer to each other. The two reinforcing plates 9 can be manipulated to fix workpieces of different specifications, improving the stability of subsequent welding and reinforcement processes.

[0029] A top plate 6 is connected to the top of the front side of the device frame 1. A lifting cylinder 7 is installed in the middle of the top plate 6. A welding assembly 8 is installed at the bottom of the lifting cylinder 7. A magnetic stone 20 is connected to the front side of the top plate 6.

[0030] The bottom of the base plate 5 is connected to the base 10. The base 10 is connected to the limit block 25 by the spring 24. The side of the limit block 25 away from the spring 24 is hinged to the protective baffle 13. The upper surface of the protective baffle 13 is connected to the magnet 22. The magnet 22 is matched with the magnet 20.

[0031] The outer end of the protective baffle 13 extends to the front side of the base 10 and is connected to the operating handle 21;

[0032] The top and bottom of the base 10 are connected to guide grooves 23 that match the limiting block 25. The limiting block 25 slides along the guide groove 23, which can pull the protective baffle 13 to the front side of the base 10, so that the protective baffle 13 can rotate until the magnet 22 and the magnet 20 are magnetically attracted. This allows the protective baffle 13 to effectively shield the front side of the device, preventing workers from contacting the equipment while it is in operation and improving the safety of the device.

[0033] In this embodiment, the motor 15 and the bidirectional screw 12, in conjunction with the guide rod 11, enable the two moving frames 4 to move linearly closer and further apart, facilitating the adjustment of the spacing between the two reinforcing plates 9 according to the specifications of the workpiece. The motor 17, drive rod 2, and gear 18 drive the rotating rod 3 and the connected gear 19 to rotate, causing the rotating frame 16 to rotate as a whole, which facilitates the overall rotation of the fixed workpiece. The rotating block 26 and the bidirectional screw 29, in conjunction with the guide rod 28, allow the two moving rods 27 to move linearly along the bidirectional screw 29, moving closer and further apart, thus controlling the two reinforcing plates 9 to fix workpieces of different specifications.

[0034] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
