Description

Technical Field

[0001] This utility model relates to the field of oiling equipment technology, specifically to an oiling mechanism for a valve body and valve cover oiling machine. Background Technology

[0002] As key components in various fluid control systems, the valve body and valve cover directly affect the system's stability and safety through their sealing performance and service life. To ensure that the sealing surfaces of the valve body and valve cover have good lubrication performance and corrosion resistance, the oiling process is an indispensable and crucial step. Figure 2 Taking a gate valve as an example, the external thread 201 on the valve cover 2 is connected to the internal thread 301 in the valve body 3. Through the oiling process, it serves two purposes: firstly, lubrication, making the valve body and valve cover easier to assemble; and secondly, sealing, as the grease forms an oil film within the thread gaps, filling them and effectively preventing internal media leakage. In the mass production of gate valves, most use a valve body and valve cover oiling machine for oiling. The oiling machine uses an oiling mechanism to evenly apply grease to the valve body and valve cover.

[0003] Most oiling machines on the market use brushes for oiling. However, these brushes wear down during use, requiring constant adjustments to their position, which makes operation cumbersome and severely impacts production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an oiling mechanism for a valve body and valve cover oiling machine.

[0005] The technical solution of this utility model is as follows:

[0006] An oiling mechanism for a valve body and valve cover oiling machine is fixedly installed on a workbench inside the oiling machine. It includes a valve cover oiling mechanism and a valve body oiling mechanism. The valve cover oiling mechanism and the valve body oiling mechanism are arranged side by side and fixed on the workbench by a base. A column is provided on the base and is arranged perpendicular to the base.

[0007] The valve cover oiling mechanism and the valve body oiling mechanism have the same structure, both including an oiling lifting mechanism, an oiling rotating mechanism, and a brush stepping mechanism. The oiling lifting mechanism includes a fixed base, which is sleeved on the column. The fixed base is driven to lift and lower by a servo electric cylinder fixed to the upper end face of the column. The oiling rotating mechanism includes a motor and a rotating disk. The motor is fixed to the lower end face of the fixed base and drives the rotating disk to rotate. The brush stepping mechanism is fixed to the rotating disk and controls the lifting and lowering of the brush by a stepping push rod to compensate for the wear of the brush.

[0008] Furthermore, the base is provided with two sleeves, and the columns of the valve cover oiling mechanism and the valve body oiling mechanism are respectively located inside the sleeves, with the lower end of the column being interference-fitted with the sleeve.

[0009] Furthermore, the servo electric cylinder includes a servo motor section and a telescopic cylinder section. The lower end face of the servo motor section is fixedly disposed on the upper end of the column. The upper end of the servo motor section and the upper end of the telescopic cylinder section are connected through a transmission box. The telescopic cylinder section is provided with a telescopic rod, which is driven to rise and fall by the servo motor section.

[0010] Furthermore, the fixed base includes a guide part and a fixed part, which are connected by a crossbeam. The crossbeam has an "I" shaped cross section. The guide part has a guide hole and is sleeved on the axial side of the column through the guide hole. The guide hole is clearance-fitted with the column. The upper end face of the fixed part has a telescopic rod connection hole and is connected to the telescopic rod. The servo electric cylinder drives the fixed base to move up and down along the column.

[0011] Furthermore, the lower end of the fixing part is provided with a threaded hole, and the motor is fixed to the lower end surface of the fixing base by screws. The output end of the motor is connected to the rotating disk to drive the rotating disk to rotate.

[0012] Furthermore, the brush stepping mechanism includes a fixed plate, a stepping push rod, and a brush. The upper end of the fixed plate is eccentrically located on the lower end face of the rotating disk. The fixed plate is L-shaped. The upper end of the stepping push rod is fixedly connected to the lower end face of the rotating disk. The two sides of the stepping push rod are fixedly located on the inner side of the fixed plate to form a complete constraint. The output end of the stepping push rod is fixedly connected to the handle of the brush. The stepping push rod controls the lifting and lowering of the brush to compensate for the wear of the brush. The rotation of the rotating disk drives the brush to rotate around the central axis of the rotating disk.

[0013] Furthermore, it also includes an oil storage tank and a metering pump. The oil storage tank is cylindrical and fixedly mounted on the workbench, located in the middle of the two columns. The metering pump is connected to the inside of the oil storage tank through a hose. The metering pump has a first oil outlet and a second oil outlet on its two sides, respectively. The first oil outlet and the second oil outlet are respectively connected to the valve cover fixture and the valve body fixture through the hose. An oil pressure gauge is installed in the middle of the metering pump.

[0014] Furthermore, it also includes a valve cover fixture and a valve body fixture, which are respectively located directly below the motor. The valve cover fixture includes an outer layer and an inner layer, and the valve body fixture includes an outer layer and an inner layer. Both the outer layer of the valve cover fixture and the outer layer of the valve body fixture have countersunk holes at their bottom centers, and are fixed to the worktable through the countersunk holes. The inner layers of the valve cover fixture and the inner layers of the valve body fixture are made of plastic and are respectively located in the cavities of the outer layers of the valve cover fixture and the outer layers of the valve body fixture, and are interference-fitted with the outer layers of the valve cover fixture and the outer layers of the valve body fixture.

[0015] Furthermore, the inner wall of the outer layer of the valve cover fixture is provided with several anti-rotation grooves, and the outer wall of the inner layer of the valve cover fixture is provided with several anti-rotation keys. The anti-rotation grooves and the anti-rotation keys cooperate to prevent the inner layer of the valve cover fixture from rotating.

[0016] Furthermore, the servo electric cylinder, the motor, the stepper push rod, and the metering pump are all connected to the power supply box of the oiling machine and are linked and coordinated through a PLC control system.

[0034] Please see Figures 1 to 8 This utility model provides a technical solution:

[0035] An oiling mechanism for a valve body and valve cover oiling machine is fixedly installed on a workbench 106 inside the oiling machine 1. It includes a valve cover oiling mechanism 4 and a valve body oiling mechanism 5. The valve cover oiling mechanism 4 and the valve body oiling mechanism 5 are arranged side by side and fixed on the workbench 106 by a base 8. A column 9 is provided on the base 8 and is perpendicular to the base 8.

[0036] The valve cover oiling mechanism 4 and the valve body oiling mechanism 5 have the same structure, both including an oiling lifting mechanism, an oiling rotating mechanism, and a brush 16 stepping mechanism. The oiling lifting mechanism includes a fixed base 10, which is sleeved on the column 9. The fixed base 10 is driven to lift and lower by a servo electric cylinder 11 fixed to the upper end face of the column 9. The oiling rotating mechanism includes a motor 12 and a rotating disk 13. The motor 12 is fixed to the lower end face of the fixed base 10 and drives the rotating disk 13 to rotate. The brush 16 stepping mechanism is fixed to the rotating disk 13 and controls the lifting and lowering of the brush 16 by a stepping push rod 15 to compensate for the wear of the brush 16.

[0037] Specifically, such as Figure 1As shown, the power supply box 101 is located inside the bottom frame of the oiling machine 1. The power supply box 101 is equipped with a PLC control system. The upper part of the front of the oiling machine 1 is equipped with a PLC interaction port 105. Through the PLC interaction port 105, relevant parameters (such as rotation speed, feed speed, oil output, etc.), manual or automatic or single-step functions, counting functions, and preset program quick change functions can be set.

[0038] Specifically, such as Figure 1 As shown, the oiling machine 1 is also equipped with safety protection facilities, including a safety light curtain 103 and a two-hand start button 102. The oiling mechanism will only start when the safety light curtain 103 detects that there are no foreign objects in the area and the two-hand start button 102 is pressed at the same time. A three-color safety light 104 is provided above the oiling machine 1 and an indicator light 107 is provided between the two-hand start button 102. The PLC control system can detect and realize the sound and light alarm.

[0039] Specifically, such as Figure 3 As shown, the base 8 is provided with two sleeves. The column 9 of the valve cover oiling mechanism 4 and the column 9 of the valve body oiling mechanism 5 are respectively located in the sleeves. The lower end of the column 9 is interference-fitted with the sleeve.

[0040] Through the above structure, the base 8 absorbs vibration and lowers the center of gravity, making the oiling mechanism safe and stable during operation.

[0041] Specifically, such as Figure 5 As shown, the servo electric cylinder 11 includes a servo motor part 1101 and a telescopic cylinder part 1103. The lower end face of the servo motor part 1101 is fixedly disposed on the upper end of the column 9. The upper end of the servo motor part 1101 and the upper end of the telescopic cylinder part 1103 are connected through a transmission box 1102. The telescopic cylinder part 1103 is provided with a telescopic rod 1104, which is driven to lift and lower by the servo motor part 1101.

[0042] Specifically, the preferred model of the servo electric cylinder 11 is the RKD065 base plate type folding electric cylinder with a maximum load of 500kg. The transmission principle of the servo electric cylinder 11 is a relatively mature existing technology, which is briefly described here: a pulley is provided in the transmission box 1102, and a lead screw is connected to the telescopic rod 1104. The lead screw is connected to the pulley, and the output end of the servo motor 1101 drives the pulley to rotate. The pulley drives the lead screw to rotate, thereby raising and lowering the telescopic rod 1104.

[0043] Specifically, such as Figure 6 and Figure 7As shown, the fixed base 10 includes a guide part 1001 and a fixed part 1004. The guide part 1001 and the fixed part 1004 are connected by a crossbeam 1003. The crossbeam 1003 has an "I" shaped cross section. The guide part 1001 is provided with a guide hole 1002. The guide part 1001 is sleeved on the axial side of the column 9 through the guide hole 1002. The guide hole 1002 is clearance-fitted with the column 9. The upper end face of the fixed part 1004 is provided with a telescopic rod connecting hole 1005. The telescopic rod connecting hole 1005 is connected to the telescopic rod 1104. The servo electric cylinder 11 drives the fixed base 10 to move up and down along the column 9.

[0044] Using the above structure, the height of the brush 16 is changed by raising and lowering the fixed base 10, thus completing the oiling process.

[0045] Specifically, such as Figure 7 As shown, the lower end of the fixing part 1004 is provided with a threaded hole 1006. The motor 12 is fixed to the lower end surface of the fixing base 10 by screws 24. The output end of the motor 12 is connected to the rotating disk 13 to drive the rotating disk 13 to rotate.

[0046] Specifically, such as Figure 5 and Figure 6 As shown, the stepping mechanism of the brush 16 includes a fixed plate 14, a stepping push rod 15, and a brush 16. The upper end of the fixed plate 14 is eccentrically located on the lower end face of the rotating disk 13. The fixed plate 14 is L-shaped. The upper end of the stepping push rod 15 is fixedly connected to the lower end face of the rotating disk 13. The two sides of the stepping push rod 15 are fixedly located on the inner side of the fixed plate 14 to form a complete constraint. The output end of the stepping push rod 15 is fixedly connected to the handle of the brush 16. The stepping push rod 15 controls the lifting and lowering of the brush 16 to compensate for the wear of the brush 16. The rotation of the rotating disk 13 drives the brush 16 to rotate around the central axis of the rotating disk 13.

[0047] With the above structure, the brush 16 stepping mechanism and the PLC control system accumulate wear data of the brush 16, so as to automatically adjust the height position of the brush 16 to compensate for the amount of wear, thereby improving the oiling quality and stability.

[0048] Specifically, such as Figure 8As shown, it also includes an oil storage tank 18 and a metering pump 17. The oil storage tank 18 is cylindrical and fixedly mounted on the workbench 106, located in the middle of the two columns 9. The metering pump 17 is connected to the inside of the oil storage tank 18 through a hose 25. The metering pump 17 has a first oil outlet 1701 and a second oil outlet 1702 on its two sides, respectively. The first oil outlet 1701 and the second oil outlet 1702 are respectively connected to the valve cover fixture 6 and the valve body fixture 7 through the hose 25. An oil pressure gauge 1703 is located in the middle of the metering pump 17.

[0049] With the above structure, a metering pump 17 is set to achieve metered oil application, reducing oil waste and making the oil application thickness more uniform.

[0050] Specifically, such as Figure 3 and Figure 4 As shown, it also includes a valve cover fixture 6 and a valve body fixture 7. The valve cover fixture 6 and the valve body fixture 7 are respectively located directly below the motor 12. The valve cover fixture 6 includes an outer valve cover fixture 19 and an inner valve cover fixture 20. The valve body fixture 7 includes an outer valve body fixture 21 and an inner valve body fixture 22. The bottom center of the outer valve cover fixture 19 and the outer valve body fixture 21 are provided with countersunk holes 23, which are used to fix the fixtures on the workbench 106. The inner valve cover fixture 20 and the inner valve body fixture 22 are made of plastic and are respectively located in the cavities of the outer valve cover fixture 19 and the outer valve body fixture 21, respectively, and are interference-fitted with the outer valve cover fixture 19 and the outer valve body fixture 21.

[0051] Specifically, the inner layer 20 of the valve cover fixture and the inner layer 22 of the valve body fixture are preferably made of nylon or polytetrafluoroethylene.

[0052] Specifically, such as Figure 4 As shown, the inner wall of the outer layer 19 of the valve cover fixture is provided with a plurality of anti-rotation grooves 1901, and the outer wall of the inner layer 20 of the valve cover fixture is provided with a plurality of anti-rotation keys 2001. The anti-rotation grooves 1901 and the anti-rotation keys 2001 cooperate to prevent the inner layer 20 of the valve cover fixture from rotating.

[0053] The above structure enables quick replacement of fixtures through the separation of inner and outer layers, while the inner layer, made of plastic, protects the product surface.

[0054] Specifically, the servo electric cylinder 11, the motor 12, the stepper push rod 15 and the metering pump 17 are all connected to the power supply box 101 of the oiling machine 1 and are linked and coordinated through the PLC control system.

[0055] In this embodiment, when using the equipment, the relevant technicians first assemble the valve cover oiling mechanism 4 and the valve body oiling mechanism 5 in sequence, adjust the radial position of the fixing plate 14 so that the rotation diameter of the brush 16 is aligned with the external thread 201 and the internal thread 301, then place the valve cover 2 in the valve cover fixture 6 and the valve body 3 in the valve body fixture 7, then remove both hands from the workbench 106 area, and simultaneously press the two-hand start button 102. The motor 12 starts first, driving the rotating disk 13 to rotate, and then the servo... When the servo electric cylinder 11 is activated, it pushes the fixed seat 10 down along the column 9. When it reaches a suitable height, the metering pump 17 is activated, squeezing out a metered amount of grease onto the surfaces of the internal thread 301 and the external thread 201. Then, the brush 16 applies the grease to the internal thread 301 and the external thread 201. After the application is completed, the servo electric cylinder 11 drives the fixed seat 10 to rise. Then, the motor 12 stops. At this time, the relevant technicians can safely enter the workbench 106 area to remove the valve body 3 and the valve cover 2 from the fixture.

[0056] In this embodiment, the PLC system has a counting function. When the amount of oil applied reaches a set threshold, the PLC system calculates the amount of wear based on the rotation speed, feed rate, oil output, and a given empirical coefficient. Based on the amount of wear, the PLC system controls the stepper push rod 15 to make fine adjustments, so that the brush 16 moves to compensate for the amount of wear. This ensures that the brush 16 is always in close contact with the product throughout its service life, improving the oiling quality and stability, and making full use of the service life of the brush 16.

[0057] The parts of this utility model not described are existing or known technologies.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
