Technical Field
[0001] This invention relates to the field of variable diameter pipe fitting manufacturing technology, specifically a tooling for rust prevention treatment of the surface of pump and valve variable diameter pipe fittings. Background Technology
[0002] A reducing pipe fitting is a type of pipe fitting used to connect pipes of different diameters. It is commonly used in piping systems to achieve a transition or adjustment of pipe diameters. A reducing pipe fitting can decrease the diameter of one pipe to a smaller one, or increase the diameter of one pipe to a larger one.
[0003] According to Chinese Patent Publication No. CN213377513U, a rust-prevention treatment device for the surface of pump and valve reducing pipe fittings is disclosed. The device includes a rust-prevention treatment apparatus, a vibrating drain belt placed at the discharge end of the apparatus, a frame, and a chain guide rail fixed to the upper surface of the frame's inner cavity. The chain guide rail includes a sinking track, a discharge position on the left side, and a loading position on one side of the discharge position. The frame includes legs, and extension chains are fixed to both the chain guide rail and the sinking track. The extension chains are connected to a holding basket frame via a fixing hook installed at their lower ends. A rust-preventive liquid pool is placed at the lower end of the frame. This rust-preventive treatment device allows the rust-preventive liquid to completely cover the pump and valve reducing pipe fittings, providing comprehensive rust protection. Dripping rust-preventive liquid is collected from a drain hole into the inner cavity and then flows into a connected rust-preventive liquid pool through a return hole for collection and reuse.
[0004] However, when manufacturing reducing pipe fittings, the outer surface needs to be ground and polished. Due to the arc-shaped structure of the reducing pipe fittings, the inner and outer surfaces cannot be ground and polished simultaneously and conveniently. Therefore, a device is needed to solve the above problem. Summary of the Invention
[0005] To address the problems in the prior art, this invention provides a tooling for rust prevention treatment of the surface of pump and valve reducing pipe fittings.
[0006] The technical solution adopted by this invention to solve its technical problem is: a rust-proofing fixture for the surface of a pump valve reducing pipe fitting, comprising an automatic closing device, a polishing and grinding device, and a support adjustment device. The polishing and grinding device is mounted on the support adjustment device, and the automatic closing device is mounted on the polishing and grinding device. The support adjustment device includes a fixed mounting frame, a first motor, a drive gear, a fixed support plate, and a rotating gear ring.

The first motor is fixedly mounted on the fixed mounting frame. The drive gear is rotatably engaged with the fixed support plate, and the drive end of the first motor is fixedly connected to the middle part of the upper end of the drive gear. The drive gear is meshed with the bottom of the rotating gear ring. The first motor drives the drive gear to rotate forward and backward, and the forward and reverse rotating drive gear can drive the rotating gear ring to rotate rapidly forward and backward. Thus, the rotating gear ring can drive the polishing and grinding box to rotate forward and backward, so that the polishing abrasive in the polishing and grinding box can fully contact and polish the outer surface of the reducing pipe.
[0007] Preferably, the automatic closing device includes a sealing cover plate, a sealing clamping plate, a first electric push rod, and a fixed mounting plate. The fixed mounting plate is evenly distributed on the lower outer side of the sealing cover plate. The first electric push rod is symmetrically fixedly mounted on the fixed mounting plate, and the upper end of the first electric push rod is fixedly connected to the sealing cover plate. The sealing clamping plate is evenly fixedly connected to the bottom of the outer end of the sealing cover plate. By evenly setting the locking and limiting body on the polishing and grinding box, the reducing pipe can be evenly fixed in the polishing and grinding box. The rotating gear ring can drive the polishing and grinding box to rotate in both directions, so that the abrasive in the polishing and grinding box can fully contact and polish the outer surface of the reducing pipe. This allows both the outer and inner surfaces of the reducing pipe to be polished and rust-removed simultaneously and quickly. During the polishing process, the polishing condition of the sealing cover plate and the inside of the polishing and grinding box can be observed through a transparent observation plate.
[0008] Preferably, a transparent observation plate is fixedly installed at the upper center of the sealing cover.
[0009] Preferably, the transparent observation plate is made of transparent plastic, and a wear-resistant film is provided at the bottom of the transparent observation plate.
[0010] Preferably, the polishing and grinding device includes a sealing groove, a locking and limiting body, and a polishing and grinding box. The sealing groove is evenly opened at the upper end of the polishing and grinding box, and the locking and limiting body is evenly arranged on the polishing and grinding box.
[0011] Preferably, the locking and limiting body includes an arc-shaped locking cover, a sliding adjustment plate, a fixed frame, a second electric push rod, and a push-pull control plate. The fixed frame is symmetrically arranged, the second electric push rod is fixedly installed on the fixed frame, the push-pull control plate is fixedly connected to the front end of the fixed frame, the sliding adjustment plate is symmetrically fixedly connected to the side end of the fixed frame away from the second electric push rod, and the arc-shaped locking cover is fixedly connected between the sliding adjustment plates. By starting the second motor to drive the drive shaft and the auxiliary stirring impeller to rotate rapidly, the abrasive in the polishing box can quickly contact the reducing pipe in the polishing box, making the polishing thorough and preventing the abrasive in the polishing box from accumulating.
[0012] Preferably, the fixed frame is fixedly installed on the polishing box, the sliding adjustment plate is slidably engaged with the polishing box, the fixed mounting plate is fixedly installed on the polishing box, the sealing plate is adapted to the sealing groove, and the upper end of the rotating toothed ring is fixedly connected to the middle of the bottom end of the polishing box.
[0013] Preferably, the drive shaft is rotatably engaged in the middle of the polishing and grinding box, the auxiliary stirring impeller is uniformly fixedly installed on the drive shaft, a second motor is fixedly installed in the middle of the bottom end of the polishing and grinding box, and the drive end of the second motor is fixedly connected to the bottom end of the drive shaft, and a maintenance and installation groove is provided on the rotating gear ring.
[0014] The beneficial effects of this invention are:
[0015] I. This invention features a locking and limiting body evenly arranged on the polishing and grinding box. The locking and limiting body can evenly fix the reducing pipe in the polishing and grinding box. The rotating gear ring can drive the polishing and grinding box to rotate in both directions, so that the abrasive in the polishing and grinding box can fully contact and grind the outer surface of the reducing pipe. This allows both the outer and inner surfaces of the reducing pipe to be polished and rusted simultaneously and quickly. Furthermore, the polishing process can be observed through a transparent observation plate on the sealing cover and inside the polishing and grinding box.
[0016] Second, by starting the second motor to drive the drive shaft and auxiliary stirring impeller to rotate rapidly, the present invention can make the abrasive in the polishing box come into contact with the reducing pipe in the polishing box quickly, so that the polishing is thorough and complete, and also prevents the abrasive in the polishing box from accumulating together.

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0029] The invention will be further described below with reference to the accompanying drawings. Example 1
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a rust-proofing fixture for the surface of a pump valve reducing pipe fitting according to the present invention includes an automatic closing device 1, a polishing and grinding device 2, and a support adjustment device 3. The polishing and grinding device 2 is mounted on the support adjustment device 3, and the automatic closing device 1 is mounted on the polishing and grinding device 2. The support adjustment device 3 includes a fixed mounting bracket 4, a first motor 5, a drive gear 6, a fixed support plate 7, and a rotating gear ring 8. The bottom end of the rotating gear ring 8 is rotatably engaged with the middle of the fixed support plate 7. The fixed mounting bracket 4 is fixedly mounted on the outside of the fixed support plate 7. The first motor... 5 is fixedly installed on the fixed mounting bracket 4. The drive gear 6 is rotated and snapped onto the fixed support plate 7. The drive end of the first motor 5 is fixedly connected to the upper middle part of the drive gear 6. The drive gear 6 is meshed with the bottom of the rotating gear ring 8. The first motor 5 drives the drive gear 6 to rotate forward and backward. The forward and reverse rotation of the drive gear 6 can drive the rotating gear ring 8 to rotate forward and backward quickly. Thus, the rotating gear ring 8 can drive the polishing and grinding box 16 to rotate forward and backward, so that the polishing sand in the polishing and grinding box 16 can fully contact and polish the outer surface of the reducing pipe.
[0031] like Figure 4 As shown, the automatic closing device 1 includes a sealing cover plate 10, a sealing clamping plate 11, a first electric push rod 12, and a fixed mounting plate 13. The fixed mounting plate 13 is evenly distributed on the lower outer side of the sealing cover plate 10. The first electric push rod 12 is symmetrically fixedly mounted on the fixed mounting plate 13, and the upper end of the first electric push rod 12 is fixedly connected to the sealing cover plate 10. The sealing clamping plate 11 is evenly fixedly connected to the bottom of the outer end of the sealing cover plate 10. The first electric push rod 12 can support and lift the sealing cover plate 10 from the polishing box 16, and then place the polishing sand into the polishing box 16.
[0032] A transparent observation plate 9 is fixedly installed at the upper middle part of the sealing cover plate 10. The transparent observation plate 9 is made of transparent plastic and has a wear-resistant film at the bottom. During the polishing process, the polishing condition inside the sealing cover plate 10 and the polishing box 16 can be observed through the transparent observation plate 9.
[0033] like Figure 5 As shown, the polishing and grinding device 2 includes a sealing groove 14, a locking and limiting body 15, and a polishing and grinding box 16. The sealing groove 14 is evenly opened at the upper end of the polishing and grinding box 16, and the locking and limiting body 15 is evenly arranged on the polishing and grinding box 16. Through the locking and limiting body 15, multiple variable diameter pipes can be evenly fixed in the polishing and grinding box 16 for polishing.
[0034] like Figure 6 As shown, the locking and limiting body 15 includes an arc-shaped locking cover 17, a sliding adjustment plate 18, a fixed frame 19, a second electric push rod 20, and a push-pull control plate 21. The fixed frame 19 is symmetrically arranged, the second electric push rod 20 is fixedly installed on the fixed frame 19, the push-pull control plate 21 is fixedly connected to the front end of the fixed frame 19, the sliding adjustment plate 18 is symmetrically fixedly connected to the side end of the fixed frame 19 away from the second electric push rod 20, and the arc-shaped locking cover 17 is fixedly connected between the sliding adjustment plates 18. Through the second electric push rod 20, the sliding adjustment plate 18 can be slid along the polishing and grinding box 16 by using the push-pull control plate 21, so that the arc-shaped locking cover 17 slides towards the middle of the polishing and grinding box 16. Then, the variable diameter tube to be polished is placed in the arc-shaped locking cover 17, and then the arc-shaped locking cover 17 slides back to its original position. At this time, the variable diameter tube can be clamped and fixed between the arc-shaped locking cover 17 and the polishing and grinding box 16 by the arc-shaped locking cover 17.
[0035] The fixed frame 19 is fixedly installed on the polishing box 16. The sliding adjustment plate 18 is slidably connected to the polishing box 16. The fixed mounting plate 13 is fixedly installed on the polishing box 16. The sealing plate 11 is adapted to the sealing groove 14. The upper end of the rotating gear ring 8 is fixedly connected to the middle of the bottom end of the polishing box 16. The polishing box 16 can be driven to rotate in both directions by rotating the rotating gear ring 8 in both directions.
[0036] The working principle of Example 1 is as follows: The device can be fixedly installed at a designated location through the fixing holes opened on the fixed support plate 7. By activating the first electric push rod 12, the sealing cover plate 10 can be lifted from the polishing box 16. Then, the polishing sand is placed in the polishing box 16. Then, each of the second electric push rods 20 is activated. Through the push-pull control plate 21, the sliding adjustment plate 18 can be slid along the polishing box 16 by the second electric push rod 20, so that the arc-shaped clamping cover 17 slides towards the middle of the polishing box 16. Then, the variable diameter tube to be polished is placed in the arc-shaped clamping cover 17. Then, the arc-shaped clamping cover 17 slides back to its original position. At this time, the variable diameter tube can be clamped and fixed between the arc-shaped clamping cover 17 and the polishing box 16 by the arc-shaped clamping cover 17.
[0037] Then, the first electric push rod 12 is activated, causing the sealing cover plate 10 to move downwards and the sealing clip plate 11 to be inserted into the sealing clip groove 14. Then, the first electric motor 5 is activated, driving the drive gear 6 to rotate forward and backward. The forward and backward rotating drive gear 6 can drive the rotating gear ring 8 to rotate rapidly forward and backward. Thus, the rotating gear ring 8 can drive the polishing and grinding box 16 to rotate forward and backward, so that the abrasive in the polishing and grinding box 16 can fully contact and polish the outer surface of the reducer. This allows both the outer and inner surfaces of the reducer to be polished and rusted simultaneously and quickly. During the polishing process, the polishing condition of the sealing cover plate 10 and the inside of the polishing and grinding box 16 can be observed through the transparent observation plate 9. Example 2
[0038] Based on Example 1, such as Figure 7 and Figure 8 As shown, the drive shaft 23 is rotatably engaged in the middle of the polishing and grinding box 16. The auxiliary stirring impeller 22 is evenly fixedly installed on the drive shaft 23. The second motor 24 is fixedly installed in the middle of the bottom end of the polishing and grinding box 16, and the drive end of the second motor 24 is fixedly connected to the bottom end of the drive shaft 23. The rotating gear ring 8 is provided with a maintenance and installation groove.
[0039] In implementing this embodiment, by starting the second motor 24 to drive the drive shaft 23 and the auxiliary stirring impeller 22 to rotate rapidly, the abrasive in the polishing box 16 can quickly come into contact with the reducing pipe in the polishing box 16, so that the polishing is thorough and complete, and the abrasive in the polishing box 16 will not gather together.
