Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a valve disc grinding device. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc., and have functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. The valve disc is the core component of the butterfly valve. It is disc-shaped and rotates around the valve shaft to open and close the valve.

[0003] Patent No. 202122347091.4 discloses a valve grinding and repair machine tool. This device adjusts the distance and height of the grinding space according to the size of the valve to be ground, pulls the top plate to move the distance between the visible plate and the grinding space, and uses a fixing screw to confirm the height, thereby ensuring grinding efficiency while ensuring eye safety.

[0004] However, existing valve grinding and repair machine tools use a structure such as a motor, grinder, and rotary bearing to grind valves. However, the position of the motor is fixed, which limits the range of valve grinding. In addition, after the valve grinding is completed, the processed valve needs to be removed first, and then another valve to be processed needs to be placed on the processing base. The operation steps are cumbersome and the workload is large, which has a certain impact on the processing efficiency of valves. Therefore, a valve disc grinding device is designed. Utility Model Content

[0005] In view of the problems in the background art, the present invention provides a valve disc grinding device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a valve disc grinding device, including an operating table. A fixed frame is welded to one side of the operating table. A motor B is bolted inside the fixed frame. A threaded rod is keyed to the power output end of the motor B. A drive sleeve is threaded to the outside of the threaded rod. A drive frame is screwed to the outside of the drive sleeve. An electric push rod is bolted to the inside of the drive frame. A motor A is screwed to one side of the electric push rod. A grinding wheel for processing valve discs is keyed to the power output end of the motor A. A motor C is bolted inside the operating table. A drive rod is keyed to the power output end of the motor C. A gear is splined to the outside of the drive rod. A placement frame is meshed with the gear. A toothed groove is opened at the bottom of the placement frame to mesh with the gear.

[0007] By adopting the above technical solution, when the valve disc to be processed is fixed inside the fixed frame, the electric push rod in the drive frame drives one side of the motor A, so that the grinding wheel on the motor A contacts the surface of the valve disc. Then the motor A drives the grinding wheel to rotate, so that the grinding wheel processes the valve disc. At the same time, the motor B in the fixed frame drives the threaded rod to rotate, and the drive sleeve slides in the limiting groove opened in the fixed frame, so that the drive sleeve moves axially outside the threaded rod. Then the drive sleeve drives the drive frame to move, so that the drive frame drives the grinding wheel to grind different positions on the valve disc, thereby improving the processing efficiency of the valve disc.

[0008] After the valve disc on the placement rack is processed, the processed valve disc is released from its fixation. Then, the motor C in the operating table drives the drive rod to rotate, which in turn drives the gear to rotate. This causes the gear to mesh with the tooth groove and move the placement rack. The placement rack then moves the processed valve disc off the operating table. At the same time, another valve disc that needs to be processed on the placement rack moves to the operating table, thereby improving the processing efficiency of the valve disc.

[0009] Specifically, the fixed frame is symmetrically screwed with electric telescopic rod A and electric telescopic rod B. A limit plate A is screwed at the end of electric telescopic rod A, and a limit plate B is screwed at the end of electric telescopic rod B.

[0010] By adopting the above technical solution, when the placement frame moves the valve disc into the fixed frame, the electric telescopic rod A and electric telescopic rod B, which are symmetrically installed in the fixed frame, respectively drive the limiting plate A and the limiting plate B to move, so that the limiting plate A and the limiting plate B respectively contact the surface of the valve disc, thereby facilitating the fixing of the valve disc to be processed.

[0011] Specifically, the inner side of the operating table is symmetrically provided with sliding grooves, and the outer side of the placement frame is symmetrically welded with sliding plates.

[0012] By adopting the above technical solution, when the placement rack moves, the symmetrically welded sliding plates on the outside of the placement rack slide in the symmetrically opened grooves inside the operating table, thereby improving the stability of the placement rack movement.

[0013] Specifically, the operating table is symmetrically welded with brackets to support the placement rack.

[0014] By adopting the above technical solution, the symmetrically installed brackets on the outside of the operating table support the placement rack, thereby improving the stability of the placement rack.

[0015] Specifically, the input terminals of the electric telescopic rod A, electric telescopic rod B, motor A, motor B, and motor C are all electrically connected to the power supply terminal of an external power source.

[0016] By adopting the above technical solution, the electrical equipment can operate normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0017] The beneficial effects of this utility model are:

[0018] (1) The valve disc grinding device of this utility model, when the valve disc to be processed is fixed on the operating table, the electric push rod in the drive frame drives one side of the motor A, so that the grinding wheel on the motor A contacts the surface of the valve disc. Then the motor A drives the grinding wheel to rotate, so that the grinding wheel processes the valve disc. At the same time, the motor B in the fixed frame drives the threaded rod to rotate, and the drive sleeve slides in the limiting groove opened in the fixed frame, so that the drive sleeve moves axially outside the threaded rod. Then the drive sleeve drives the drive frame to move, so that the drive frame drives the grinding wheel to grind different positions on the valve disc, thereby improving the processing efficiency of the valve disc.

[0019] (2) The valve disc grinding device of this utility model, after the valve disc on the placement frame is processed, the valve disc is released from the fixed position. Then the motor C in the operating table drives the drive rod to rotate, and the drive rod drives the gear to rotate, so that the gear meshes with the tooth groove and drives the placement frame to move. Then the placement frame moves the processed valve disc from the operating table. At the same time, another valve disc that needs to be processed on the placement frame moves to the operating table, thereby improving the processing efficiency of the valve disc.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] To improve the processing efficiency of valve discs, as one embodiment of this utility model, such as... Figures 1 to 4 As shown, the valve disc grinding device of this utility model includes an operating table 6. A fixed frame 1 is welded to one side of the operating table 6. A motor B14 is bolted inside the fixed frame 1. A threaded rod 13 is keyed to the power output end of the motor B14. A drive sleeve 11 is threaded to the outside of the threaded rod 13. A drive frame 2 is screwed to the outside of the drive sleeve 11. An electric push rod 21 is bolted to the inside of the drive frame 2. A motor A12 is screwed to one side of the electric push rod 21. A grinding wheel 8 for processing valve discs is keyed to the power output end of the motor A12. A motor C16 is bolted inside the operating table 6. A drive rod 18 is keyed to the power output end of the motor C16. A gear 17 is splined to the outside of the drive rod 18. A placement frame 5 is meshed with the gear 17. A toothed groove 15 that meshes with the gear 17 is opened at the bottom of the placement frame 5.

[0028] When in use, when the valve disc to be processed is fixed inside the fixed frame 1, the electric push rod 21 in the drive frame 2 drives one side of the motor A12, so that the grinding wheel 8 on the motor A12 contacts the surface of the valve disc. Then the motor A12 drives the grinding wheel 8 to rotate, so that the grinding wheel 8 processes the valve disc. At the same time, the motor B14 in the fixed frame 1 drives the threaded rod 13 to rotate, and the drive sleeve 11 slides in the limiting groove opened in the fixed frame 1, so that the drive sleeve 11 moves axially outside the threaded rod 13. Then the drive sleeve 11 drives the drive frame 2 to move, so that the drive frame 2 drives the grinding wheel 8 to grind different positions on the valve disc, thereby improving the processing efficiency of the valve disc.

[0029] After the valve disc on the placement rack 5 is finished, the valve disc is released from its fixed position. Then, the motor C16 in the operating table 6 drives the drive rod 18 to rotate, which in turn drives the gear 17 to rotate. This causes the gear 17 to mesh with the tooth groove 15 and move the placement rack 5. Then, the placement rack 5 moves the finished valve disc off the operating table 6. At the same time, another valve disc that needs to be processed on the placement rack 5 is moved to the operating table 6, thereby improving the processing efficiency of the valve disc.

[0030] The threaded rod 13 and the drive rod 18 are both mounted in the bearing seats of the fixed frame 1 and the operating table 6 respectively by deep groove ball bearings, and the bearing seats are welded to the inner walls of the fixed frame 1 and the operating table 6 respectively.

[0031] To fix the valve disc that needs to be processed, for example, such as Figure 2 As shown, this utility model also includes an electric telescopic rod A3 and an electric telescopic rod B10 symmetrically fixed inside the fixing frame 1 with screws. A limit plate A4 is fixed at the end of the electric telescopic rod A3 with screws, and a limit plate B9 is fixed at the end of the electric telescopic rod B10 with screws.

[0032] When in use, when the placement frame 5 moves the valve disc into the fixed frame 1, the electric telescopic rods A3 and B10, which are symmetrically installed in the fixed frame 1, respectively drive the limiting plate A4 and the limiting plate B9 to move, so that the limiting plate A4 and the limiting plate B9 respectively contact the surface of the valve disc, thereby facilitating the fixing of the valve disc to be processed.

[0033] To improve the stability of the movement of the placement rack 5, for example, such as Figure 3 and Figure 4 As shown, the present invention also includes symmetrically provided sliding grooves 19 on the inner side of the operating table 6, and symmetrically welded sliding plates 7 on the outer side of the placement frame 5.

[0034] When in use, as the placement rack 5 moves, the symmetrically welded sliding plate 7 on the outside of the placement rack 5 slides within the symmetrically opened grooves 19 inside the operating table 6, improving the stability of the movement of the placement rack 5.

[0035] To improve the stability of the placement rack 5, for example, such as Figure 1 As shown, the present invention also includes a bracket 20 symmetrically welded to the outside of the operating table 6 to support the placement rack 5.

[0036] During use, the brackets 20 symmetrically installed on the outside of the operating table 6 support the placement rack 5, improving the stability of the placement rack 5.

[0037] For electrical equipment to function properly, for example, such as Figures 1 to 4As shown, this utility model also includes the fact that the input terminals of the electric telescopic rod A3, electric telescopic rod B10, motor A12, motor B14 and motor C16 are all electrically connected to the power supply terminal of an external power source.

[0038] When in use, the electrical equipment works normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0039] In use, the valve disc to be processed is first fixed inside the fixing frame 1. The electric telescopic rods A3 and B10, symmetrically installed inside the fixing frame 1, respectively drive the limiting plates A4 and B9 to move, causing them to contact the valve disc surface, thus facilitating the fixing of the valve disc. The electric push rod 21 inside the drive frame 2 drives one side of the motor A12, causing the grinding wheel 8 on the motor A12 to contact the valve disc surface. Subsequently, the motor A12 drives the grinding wheel 8 to rotate, allowing it to process the valve disc. Simultaneously, the motor B14 inside the fixing frame 1 drives the threaded rod 13 to rotate, and the driving sleeve 11 has a limiting groove inside the fixing frame 1. The internal sliding causes the drive sleeve 11 to move axially outside the threaded rod 13. Then, the drive sleeve 11 drives the drive frame 2 to move, which in turn drives the grinding wheel 8 to grind different positions on the valve disc, improving the processing efficiency of the valve disc. After the valve disc on the placement frame 5 is processed, the valve disc is released from its fixed position. Then, the motor C16 in the operating table 6 drives the drive rod 18 to rotate, which in turn drives the gear 17 to rotate. This causes the gear 17 to mesh with the tooth groove 15 and move the placement frame 5. Then, the placement frame 5 moves the processed valve disc off the operating table 6. At the same time, another valve disc that needs to be processed on the placement frame 5 moves to the operating table 6, thereby improving the processing efficiency of the valve disc.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
