Description

Technical Field

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

[0002] A pneumatic control valve is a specialized device that uses compressed air to control the pressure of incoming and outgoing oil. In the production of pneumatic control valves, the valve stem needs to be ground and polished to improve its sealing performance and extend its service life.

[0003] When grinding the valve stem of a pneumatic control valve, a grinding device is often required. However, the grinding rollers of the grinding device are usually of a fixed grit. When a more detailed polishing is needed after grinding the valve stem, it is necessary to replace the grinding roller with a higher grit or use a polishing device, which makes the grinding of the valve stem more complicated and affects the production of the pneumatic control valve. Therefore, a grinding device for pneumatic control valves is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A pneumatic valve polishing device of this utility model includes a base, a motor fixedly connected to the outer side of the base, a rotating plate fixedly connected to the output end of the motor, a clamping screw rotatably connected to the inner side of the base, a movable plate threadedly connected to the outer side of the clamping screw, the movable plate and the base being slidably connected, a rotating block rotatably connected to the inner side of the movable plate, the rotating block and the rotating plate cooperating, a rotating rod rotatably connected to the inner side of the base, a polishing pad fixedly connected to the outer side of the rotating rod, a polishing plate fixedly connected to the outer side of the rotating rod, gears fixedly connected to the outer side of the rotating rod, the gears meshing with each other, a rotating wheel fixedly connected to the outer side of one side of the rotating rod, a slot opened on the inner side of the rotating wheel, a pull-up spring fixedly connected to the outer side of the base, a plug fixedly connected to one end of the pull-up spring, and the plug and the base... The sliding connection allows the insert rod and slot to work together. This step involves setting up a rotating rod, polishing pad, grinding plate, gear, and insert rod. In use, the pneumatic valve stem is placed between the rotating block and the rotating plate. Then, the clamping screw is rotated, causing the rotating block and rotating plate to clamp and fix the pneumatic valve stem. The insert rod is first pulled out of the slot, then one side of the rotating rod is rotated, driving the gear to rotate, which in turn drives the other side of the rotating rod, causing the grinding plate to rotate until it is flush against the pneumatic valve stem. The insert rod is then inserted back into the slot to fix the position of the rotating rod. A motor then drives the rotating plate and the pneumatic valve stem to rotate, thus performing polishing. After polishing, the rotating rod is rotated again to make the polishing pad flush against the pneumatic valve stem, and then the pneumatic valve stem is rotated again for polishing. This allows the device to polish immediately after grinding, making the processing of the pneumatic valve stem more convenient and improving the practicality of the device.

[0006] Preferably, a groove is provided on the inner side of the base, and a baffle is slidably connected to the inner side of the groove. By setting the groove and the baffle, after the pneumatic valve stem is fixed inside the device, the baffle can be pulled to slide inside the groove, so that the baffle cooperates with the base to seal the pneumatic valve stem. This allows the debris generated during grinding and polishing to be confined inside the baffle, thus preventing contamination of the outer working environment and improving the ease of use of the device.

[0007] Preferably, the inner side of the baffle is provided with an installation groove, and an electromagnet is fixedly connected to the inner side of the installation groove. By setting the installation groove and the electromagnet, when the baffle blocks and closes the base, the electromagnet can be activated. Thus, when the valve stem of the pneumatic control valve is being ground and polished, the electromagnet will attract and collect the generated debris. This makes it easier to remove and collect the debris after the baffle moves to no longer block the base, thus improving the convenience of cleaning the device.

[0008] Preferably, a protective plate is fixedly connected to the outside of the base, and the protective plate works in conjunction with the gear. By setting the protective plate, when the electromagnet moves the debris it attracts for collection, the protective plate can shield and protect the gear, so that the gear can stay away from the debris, thus preventing wear caused by contact with the debris and extending the service life of the device.

[0009] Preferably, a lifting screw is rotatably connected to the inner side of the base, and a pressure plate is threadedly connected to the outer side of the lifting screw. By setting the lifting screw and the pressure plate, after the pneumatic valve stem is fixed, the lifting screw can be rotated to move the pressure plate down to be close to the pneumatic valve stem, thereby further limiting the pneumatic valve stem, making it more stable during grinding and improving the stability of the device.

[0010] Preferably, a roller is rotatably connected to the inner side of the pressure plate, and the roller and the rotating plate are used in conjunction. By setting the roller, when the pressure plate limits the valve stem of the pneumatic control valve, the roller will be close to the valve stem of the pneumatic control valve. Thus, when the rotating plate drives the valve stem of the pneumatic control valve to rotate, the roller will rotate synchronously, thereby reducing the friction caused by contact between the valve stem of the pneumatic control valve and the pressure plate when rotating, and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a rotating rod, polishing pad, grinding plate, gear, and insert rod, allows for the following operation: The pneumatic valve stem is placed between the rotating block and the rotating plate. The clamping screw is then rotated, causing the rotating block to clamp and fix the valve stem in conjunction with the rotating plate. The insert rod is pulled out of the slot, and then one side of the rotating rod is rotated. This rotates the gear, which in turn rotates the other side of the rotating rod, causing the grinding plate to rotate until it is flush against the valve stem. The insert rod is then inserted back into the slot to fix the position of the rotating rod. A motor then drives the rotating plate and the valve stem to rotate for polishing. After polishing, the rotating rod is rotated again to bring the polishing pad into contact with the valve stem, and the valve stem is then rotated again for further polishing. This allows for immediate polishing after initial grinding, making the processing of the pneumatic valve stem more convenient and improving the device's practicality.

[0013] 2. By setting a sliding groove and a baffle, after the pneumatic valve stem is fixed inside the device, the baffle can be pulled to slide inside the sliding groove, so that the baffle, together with the base, seals the pneumatic valve stem. This allows the debris generated during grinding and polishing to be confined inside the baffle, thus preventing contamination of the external working environment and improving the ease of use of the device.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5As shown, a pneumatic valve polishing device includes a base 1. A motor 2 is fixedly connected to the outer side of the base 1, and a rotating plate 3 is fixedly connected to the output end of the motor 2. A clamping screw 4 is rotatably connected to the inner side of the base 1, and a movable plate 5 is threadedly connected to the outer side of the clamping screw 4. The movable plate 5 and the base 1 are slidably connected. A rotating block 6 is rotatably connected to the inner side of the movable plate 5, and the rotating block 6 and the rotating plate 3 are used in conjunction. A rotating rod 7 is rotatably connected to the inner side of the base 1, and a polishing pad 8 is fixedly connected to the outer side of the rotating rod 7. A polishing plate 9 is fixedly connected to the outer side of the rotating rod 7, and a gear 10 is fixedly connected to the outer side of the rotating rod 7. The gears 10 mesh with each other. A rotating wheel 11 is fixedly connected to the outer side of one side of the rotating rod 7, and a slot 12 is opened on the inner side of the rotating wheel 11. A pull-up spring 13 is fixedly connected to the outer side of the base 1, and a plug rod 14 is fixedly connected to one end of the pull-up spring 13. The plug rod 14 is slidably connected to the base 1. 4. Used in conjunction with slot 12; This step involves setting up a rotating rod 7, polishing pad 8, grinding plate 9, gear 10, and insert rod 14. In use, the pneumatic valve stem is placed between the rotating block 6 and the rotating plate 3. Then, the clamping screw 4 is rotated so that the rotating block 6 and the rotating plate 3 clamp and fix the pneumatic valve stem. The insert rod 14 is pulled out of the slot 12 first, and then one side of the rotating rod 7 is rotated. This drives the gear 10 to rotate, and the gear 10 drives the other side of the rotating rod 7 to rotate, so that the grinding plate 9 rotates to fit tightly against the pneumatic valve stem. The insert rod 14 is then inserted back into the slot 12 to fix the position of the rotating rod 7. The motor 2 then drives the rotating plate 3 and the pneumatic valve stem to rotate, thus performing grinding. After grinding, the rotating rod 7 is rotated again so that the polishing pad 8 fits tightly against the pneumatic valve stem. The pneumatic valve stem is then rotated again for polishing. This allows the device to polish immediately after grinding, making the processing of the pneumatic valve stem more convenient and improving the practicality of the device.

[0024] Furthermore, such as Figure 1 As shown, a groove 15 is provided on the inner side of the base 1, and a baffle 16 is slidably connected to the inner side of the groove 15. By setting the groove 15 and the baffle 16, after the pneumatic valve stem is fixed inside the device, the baffle 16 can be pulled to slide inside the groove 15, so that the baffle 16 cooperates with the base 1 to seal the pneumatic valve stem. This allows the debris generated during grinding and polishing to be confined inside the baffle 16, thus preventing contamination of the outer working environment and improving the ease of use of the device.

[0025] Furthermore, such as Figure 2As shown, an installation groove 17 is provided on the inner side of the baffle 16, and an electromagnet 18 is fixedly connected to the inner side of the installation groove 17. By setting the installation groove 17 and the electromagnet 18, when the baffle 16 blocks and closes the base 1, the electromagnet 18 can be activated. Thus, when the pneumatic valve stem is being ground and polished, the electromagnet 18 will attract and collect the generated debris together. This makes it easier to remove and collect the debris after the baffle 16 moves to no longer block the base 1, improving the convenience of cleaning the device.

[0026] Furthermore, such as Figure 2 As shown, a protective plate 19 is fixedly connected to the outside of the base 1. The protective plate 19 and the gear 10 are used in conjunction. By setting the protective plate 19, when the electromagnet 18 moves the debris it attracts for collection, the protective plate 19 can shield and protect the gear 10, so that the gear 10 can stay away from the debris, and thus is less likely to wear due to contact with the debris, thereby extending the service life of the device.

[0027] Furthermore, such as Figure 1 As shown, a lifting screw 20 is rotatably connected to the inner side of the base 1, and a pressure plate 21 is threadedly connected to the outer side of the lifting screw 20. By setting up the lifting screw 20 and the pressure plate 21, after the pneumatic valve stem is fixed, the lifting screw 20 can be rotated to move the pressure plate 21 down to be close to the pneumatic valve stem, thereby further limiting the pneumatic valve stem, making it more stable during grinding and improving the stability of the device.

[0028] Furthermore, such as Figure 1 As shown, a roller 22 is rotatably connected to the inner side of the pressure plate 21, and the roller 22 and the rotating plate 3 are used in conjunction. In this step, by setting the roller 22, when the pressure plate 21 limits the valve stem of the pneumatic control valve, the roller 22 will be close to the valve stem of the pneumatic control valve. Thus, when the rotating plate 3 drives the valve stem of the pneumatic control valve to rotate, the roller 22 will rotate synchronously, thereby reducing the friction caused by contact between the valve stem of the pneumatic control valve and the pressure plate 21 when rotating, and improving the stability of the device.

[0029] Working principle: During use, the pneumatic valve stem is placed between the rotating block 6 and the rotating plate 3. Then, the clamping screw 4 is rotated to move the rotating block 6, thereby clamping and fixing the pneumatic valve stem with the rotating plate 3. The insert rod 14 is pulled out of the slot 12 first, and then one side of the rotating rod 7 is rotated. The rotating rod 7 drives the gear 10 to rotate, and the gear 10 drives the other side of the rotating rod 7 to rotate, so that the grinding plate 9 rotates to fit tightly against the pneumatic valve stem. The insert rod 14 is then inserted back into the slot 12 to fix the position of the rotating rod 7. Then, the lifting screw 20 is rotated, which drives the pressure plate 21 and the roller 22 to move down, so that the roller 22 fits tightly against the pneumatic valve stem. Then, the baffle 16 is pulled to block the pneumatic valve stem. Then, the motor 2 drives the rotating plate 3 and the pneumatic valve stem to rotate, thereby performing grinding. After grinding, the rotating rod 7 is rotated again to make the polishing pad 8 fit tightly against the pneumatic valve stem, and then the pneumatic valve stem is rotated again for polishing.
