Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of faucet valve surface treatment equipment, and particularly relates to a faucet valve surface treatment device. BACKGROUND

[0002] The faucet valve is an important valve type widely used in the petroleum, chemical industry, energy and other industries. Its main function is to control the flow of fluid in the pipeline, and is often used for flow regulation, cut-off, distribution and other operations. The working principle and performance requirements of the faucet valve require that the valve core surface has high smoothness and precision, therefore the processing quality of the valve core surface has a crucial influence on the sealing performance, service life and working efficiency of the faucet valve.

[0003] The traditional faucet valve core surface treatment method is mostly manual operation, involving polishing, polishing, painting and other processes. Due to the complicated operation process and the difficulty in achieving high-precision synchronous control, manual operation often leads to uneven surface treatment, and even may cause damage to the valve core surface, affecting its performance. In addition, the traditional processing method requires more manual intervention, and it is difficult to achieve mass production, so there is a certain bottleneck in production efficiency and cost control.

[0004] With the rapid development of industrial automation, the mechanical manufacturing field is gradually transformed towards high efficiency, precision and automation. The introduction of automated equipment can improve the stability and consistency of the faucet valve surface treatment process to a certain extent, thereby improving the quality of the product.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0039] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Example: Figure 1 As shown, a device for surface treatment of a stopcock valve includes a base shell 1, an inner shell 2 installed inside the base shell 1, a treatment device, a synchronization unit 3 for driving the treatment device to rise and fall, an adsorption unit 4 for adsorbing debris after treatment by the treatment device, and an auxiliary unit 5 for driving the treatment device to treat the stopcock valve. The treatment device includes a grinding unit 6 for grinding the stopcock valve, a polishing unit 9 for polishing the stopcock valve, a painting unit 8 for painting the polished stopcock valve, and a drying unit 7 for drying the painted stopcock valve. The inner shell 2 includes a connecting bracket 201, on which a bracket plate 202 is fixedly installed. The connecting bracket 201 is connected to the synchronization unit 3 and the adsorption unit 4.

[0042] Through the above scheme, the processing devices inside the base shell 1 form a modular assembly, which centralizes the surface treatment of the plug valve, facilitates various treatments on the surface of the plug valve, saves time, and improves efficiency. The synchronization unit 3 drives the grinding unit 6, drying unit 7, painting unit 8 and polishing unit 9 to move up and down, so that the grinding unit 6, drying unit 7, painting unit 8 and polishing unit 9 can treat the surface of the plug valve.

[0043] like Figure 2 ,Figure 3 As shown, the synchronization unit 3 includes a motor 301, which is fixedly mounted on the bracket plate 202. The output end of the motor 301 is connected to a gear 303 via a coupling. Gear 302 and gear 304 mesh on gear 303. Gear 302 and gear 304 are rotatably mounted on the connecting bracket 201. A lead screw 307 is fixedly mounted on gear 302. A lead screw 305 is fixedly mounted on gear 304. A lifting plate 306 is threadedly connected to lead screw 305. A lifting plate 308 is threadedly connected to lead screw 307.

[0044] With the above scheme, motor 301 is started, and the output end of motor 301 drives gear 303 to rotate through the coupling. Then, gear 303 drives gear 302 and gear 304 to rotate in the same direction. Gear 302 drives lifting plate 308 to rise or fall through lead screw 307, thereby causing lifting plate 308 to drive grinding unit 6 and drying unit 7 to rise or fall. Grinding unit 6 and drying unit 7 treat the surface of the stopcock valve. Gear 304 drives lifting plate 306 to rise or fall through lead screw 305, thereby causing lifting plate 306 to drive painting unit 8 and polishing unit 9 to rise or fall. Painting unit 8 and polishing unit 9 treat the surface of the stopcock valve.

[0045] like Figure 2 , Figure 4 , Figures 6-9 As shown, the adsorption unit 4 includes a fixed bracket 401, which is fixedly mounted on a connecting bracket 201. A lead screw 407 is rotatably mounted inside the fixed bracket 401. One end of the lead screw 407 is fixedly mounted to the output end of a motor 406 via a coupling. The motor 406 is fixedly connected to the fixed bracket 401. A connecting block 408 is threadedly connected to the lead screw 407. A pressing block 402 is fixedly mounted on the connecting block 408. A pressing disc 403 is rotatably mounted on the pressing block 402. The adsorption unit 4 also includes a rotating disc 404, which is fixedly mounted on a gear 303.

The adsorption unit 4 also includes two symmetrically distributed vacuum adsors 409, which are fixedly mounted on the fixed bracket 401. An adsorption shell 405 is connected to the vacuum adsorber 409.

[0046] Using the above method, the stopcock valve is placed on the rotating disc 404, and the motor 406 is started. The output end of the motor 406 drives the lead screw 407 to rotate via a coupling. The lead screw 407 drives the connecting block 408 to slide within the fixed bracket 401 via a thread. The connecting block 408 drives the pressing disc 403 to press the stopcock valve through the pressing block 402. Then, the rotating disc 404 is driven to rotate via the gear 303, thereby driving the stopcock valve to rotate. At the same time as the stopcock valve rotates, the lifting plate 301... Unit 6 and lifting plate 2 308 respectively drive grinding unit 6, drying unit 7, painting unit 8 and polishing unit 9 to rise or fall. Then, while grinding unit 6 and polishing unit 9 are treating the surface of the stopcock valve, two vacuum adsorbers 409 are activated. Vacuum adsorbers 409 adsorb the debris generated by grinding unit 6 and polishing unit 9 through adsorption shell 405, ensuring that there is no residue on the surface of the stopcock valve. By ensuring the cleanliness of the connecting bracket 1 201, the accumulation of debris is avoided from affecting the surface treatment quality of the stopcock valve.

[0047] like Figures 10-12 As shown, the auxiliary unit 5 includes two symmetrically distributed fixed housings 501, which are respectively fixedly mounted on lifting plate 306 and lifting plate 308.

[0048] A fixing plate 507 is fixedly installed in the middle of the fixed housing 501. A pulley 508 is rotatably mounted on the fixing plate 507. The pulley 508 has a connecting groove. The pulley 508 is connected to the pulley 503 via a belt 504. The auxiliary unit 5 also includes a rotating shaft 516. A connecting key is provided on the rotating shaft 516. The connecting key on the rotating shaft 516 is used in conjunction with a keyway 513. The connecting key on the rotating shaft 516 is connected to the connecting groove on the pulley 508. A connecting channel 509 is provided on the rotating shaft 516. The connecting channel 509 is connected to the connecting plate 515. The auxiliary unit 5 also includes two symmetrically distributed fixing blocks 514. The two fixing blocks 514 are fixedly connected to the lifting plate 306 and the lifting plate 308 respectively. The two fixing blocks 514 are threadedly connected to the lead screw 307 and the lead screw 305 respectively.

[0049] When the stopcock valve needs to be ground, polished, painted, or dried using the above method, motor 3 (502) is started. The output of motor 3 (502) drives pulley 1 (503) to rotate. Pulley 1 (503) drives pulley 2 (508) to rotate via belt 1 (504). Pulley 2 (508) drives rotating shaft 1 (516) to rotate. At this time, rotating shaft 1 (516) only cooperates with lead screw 4 (506). Rotating shaft 1 (516) drives sliding element 1 (510) to move via lead screw 4 (506). When sliding element 1 (510) drives sliding element 2 (512) to the center position of lifting plate 1 (306) or lifting plate 2 (308), motor 3 (502) stops, and hydraulic cylinder 511 is started. Hydraulic cylinder 511... The cylinder arm drives the sliding part 2 512 to slide on the sliding part 1 510. The sliding part 2 512 drives the grinding unit 6, drying unit 7, painting unit 8 or polishing unit 9 to approach the stop valve, and then grinds, polishes, paints or dries the stop valve. When it is necessary to switch the treatment of the stop valve, the cylinder 1 505 is started. The cylinder arm of the cylinder 1 505 drives the connecting plate 1 515 to move. The connecting plate 1 515 drives the rotating shaft 1 516 to slide in the pulley 2 508. At this time, the connecting plate 1 515 drives the rotating shaft 1 516 to disengage from one lead screw 4 506. The rotating shaft 1 516 is connected to another lead screw 4 506, thereby realizing the switching of the treatment function.

[0053] According to the above scheme, after the rotary valve is sprayed with paint, the painted surface is dried. The motor 704 and multiple heaters 707 are started.

Polishing pulley 2 914 is provided with keyway 3 919, which is used in conjunction with the fixed key on the rotating shaft 2 909. Polishing belt 1 913 and polishing belt 2 916 have different mesh counts.

[0058] Using the above method, when polishing the surface of the plug valve is required, motor 6 (904) is started. The output of motor 6 (904) drives pulley 3 (903) to rotate. Pulley 3 (903) drives pulley 4 (910) to rotate via belt 3 (906). Pulley 4 (910) drives rotating shaft 2 (909) to rotate. Rotating shaft 2 (909) drives polishing pulley 4 (917) to rotate. Polishing pulley 4 (917) drives polishing belt 2 (916) to rotate. Polishing belt 2 (916) polishes the surface of the plug valve. When the polishing grit needs to be changed, cylinder 2 (907) is started. The cylinder arm of cylinder 2 (907) is connected to the connecting plate. 2908 drives the rotating shaft 2909 to slide on the pulley 4910. At this time, the rotating shaft 2909 is disengaged from the polishing pulley 4917. The motor 7905 is started. The output end of the motor 7905 drives the polishing housing 911 to rotate on the fixed plate 3902. Switching to the other end of the polishing housing 911, at this time the cylinder 2907 retracts. The cylinder arm connecting plate 2908 of the cylinder 2907 drives the rotating shaft 2909 to move. At this time, the rotating shaft 2909 engages with the keyway 3919 on the polishing pulley 2914. The surface of the stopcock valve is polished by the polishing belt 1913.

[0059] Working principle: The stopcock valve is placed on the rotating disc 404. The motor 406 is started. The output of the motor 406 drives the lead screw 407 to rotate via a coupling. The lead screw 407 drives the connecting block 408 to slide within the fixed bracket 401 via a thread. The connecting block 408 drives the pressing disc 403 to press the stopcock valve through the pressing block 402. Then, the rotating disc 404 is driven to rotate via the gear 303, thereby driving the stopcock valve to rotate. At the same time as the stopcock valve rotates, the lifting plate 306 and the lifting plate 308 drive the grinding unit 6, drying unit 7, painting unit 8 and polishing unit 9 to rise or fall respectively. The motor 301 is started. The output of the motor 301 drives the gear 303 to rotate via a coupling. 03 rotates, then gear two 303 drives gear one 302 and gear three 304 to rotate in the same direction. Gear one 302 drives lifting plate two 308 to rise or fall through lead screw two 307, thereby causing lifting plate two 308 to drive grinding unit 6 and drying unit 7 to rise or fall. Grinding unit 6 and drying unit 7 treat the surface of the stopcock valve. Gear three 304 drives lifting plate one 306 to rise or fall through lead screw one 305, thereby causing lifting plate one 306 to drive painting unit 8 and polishing unit 9 to rise or fall. Motor three 502 is started. The output end of motor three 502 drives pulley one 503 to rotate. Pulley one 503 drives pulley two 508 to rotate through belt one 504. The rotating shaft 516 is driven to rotate. At this time, the rotating shaft 516 only cooperates with the lead screw 506. The rotating shaft 516 drives the sliding member 510 to move through the lead screw 506. When the sliding member 510 drives the sliding member 512 to the center position of the lifting plate 306 or the lifting plate 308, the motor 502 stops and the hydraulic cylinder 511 is started. The cylinder arm of the hydraulic cylinder 511 drives the sliding member 512 to slide on the sliding member 510. The sliding member 512 drives the grinding unit 6, drying unit 7, painting unit 8 or polishing unit 9 to approach the stop valve, and then grinds, polishes, paints or dries the stop valve. When it is necessary to switch the treatment of the stop valve, the cylinder 505 is started. The cylinder arm drives the connecting plate 515 to move, and the connecting plate 515 drives the rotating shaft 516 to slide in the pulley 508. At this time, the connecting plate 515 drives the rotating shaft 516 to disengage from a lead screw 506, and the rotating shaft 516 is connected to another lead screw 506, thereby realizing the switching of processing functions. When polishing the surface of the plug valve, the motor 602 is started. The output coupling of the motor 602 drives the first pulley to rotate. The first pulley drives the second pulley to rotate through the belt 606. The first pulley and the second pulley drive a rotating shaft 605 to rotate. The rotating shaft 605 drives the iron brush 604 to polish the surface of the plug valve through the rotating disc 603.After the stopcock valve is coated with paint, the painted surface is dried. Motor 704 and multiple heaters 707 are started to heat the surface. Motor 704 then drives fan 706 via a coupling, blowing hot air to dry the painted surface. When it's time to coat the stopcock valve with paint, pressure pump 802 is started to pressurize the paint storage box 801. The paint is then sprayed through automatic spray gun 803. When polishing the surface of the stopcock valve is required, start motor 6 (904). The output of motor 6 (904) drives pulley 3 (903) to rotate. Pulley 3 (903) drives pulley 4 (910) to rotate via belt 3 (906). Pulley 4 (910) drives rotating shaft 2 (909) to rotate. Rotating shaft 2 (909) drives polishing pulley 4 (917) to rotate. Polishing pulley 4 (917) drives polishing belt 2 (916) to rotate. Polishing belt 2 (916) polishes the surface of the stopcock valve. When polishing requires modification... When changing the mesh size, cylinder 2 (907) is activated. The cylinder arm of cylinder 2 (907) drives the rotating shaft 2 (909) to slide on pulley 4 (910) via connecting plate 2 (908). At this time, the rotating shaft 2 (909) disengages from the polishing pulley 4 (917). Motor 7 (905) is activated. The output end of motor 7 (905) drives the polishing housing 911 to rotate on fixed plate 3 (902). Switching to the other end of polishing housing 911, cylinder 2 (907) retracts. The cylinder arm of cylinder 2 (907) drives the connecting plate 2 (908) to rotate. The rotating shaft 2 909 moves, at which time the rotating shaft 2 909 engages with the keyway 3 919 on the polishing pulley 2 914, and the surface of the stopcock valve is polished by the polishing belt 1 913. Two vacuum adsorbers 409 are activated, and the vacuum adsorbers 409 adsorb the debris generated by the grinding unit 6 and polishing unit 9 through the adsorption shell 405, ensuring that there are no residues on the surface of the stopcock valve. By ensuring the cleanliness of the connecting bracket 1 201, debris accumulation is prevented from affecting the surface treatment quality of the stopcock valve.
