Description

Technical Field

[0001] This utility model relates to the technical field of valve assembly, and in particular to a pneumatic control valve assembly centering positioner. Background Technology

[0002] In the assembly process of pneumatic control valves, the valve stem, valve seat, valve cover, and sealing sleeve need to be assembled together. During assembly, to improve the sealing performance between the valve stem and valve cover, the sealing sleeve needs to be press-fitted into the mounting hole of the valve cover before the valve stem is installed on the sealing sleeve. Currently, when installing the sealing sleeve into the mounting hole of the valve cover, workers first manually place the sealing sleeve into the mounting hole, and then use a press-fitting machine to press the sealing sleeve into the mounting hole. However, this assembly process has the following problems: because the sealing sleeve cannot be guaranteed to be completely vertical after being manually placed into the mounting hole, the coaxiality between the sealing sleeve and the mounting hole cannot be guaranteed. When the sealing sleeve is pressed into the mounting hole of the valve cover using a press-fitting machine, the wear on the sealing sleeve is significant, which can easily lead to valve leakage and inconvenience in use. Therefore, an assembly alignment device is needed to ensure the coaxiality of the sealing sleeve between the mounting holes during assembly and reduce wear during assembly. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a pneumatic control valve assembly centering positioner that uses a three-jaw chuck A and a three-jaw chuck B to clamp and fix the valve cover and sealing sleeve, ensuring the coaxiality of the valve cover and sealing sleeve during assembly, reducing the wear of the sealing sleeve during press fitting, and is easy to use and highly practical.

[0004] This utility model discloses a pneumatic regulating valve assembly centering positioner, comprising a base plate, a support plate, a three-jaw chuck A, and a three-jaw chuck B. The support plate is fixedly mounted on the upper part of the base plate, and the three-jaw chuck B is located above the three-jaw chuck A. It also includes a moving mechanism, an oiling mechanism, and a pressing mechanism. The three-jaw chuck B is coaxial with the three-jaw chuck A. The oiling mechanism is mounted on the base plate and has an oiling function. The three-jaw chuck B is mounted on the moving mechanism, which has a lifting function. The pressing mechanism is mounted on the base plate and has a pressing function. When assembling the sealing slide into the mounting hole of the valve cover, the valve cover is first clamped and fixed by the three-jaw chuck A, and then the upper part of the sealing slide is clamped and fixed by the three-jaw chuck B. Since both the three-jaw chuck A and the three-jaw chuck B have… The valve cover and sealing sleeve are coaxial, with the three-jaw chuck A and B providing a centering function. The valve cover and sealing sleeve are also coaxial, as are the mounting holes on the valve cover. The moving mechanism then lowers the sealing sleeve via the three-jaw chuck B, allowing its lower part to enter the mounting hole on the upper part of the valve cover. The three-jaw chuck B ensures the sealing sleeve is vertical and coaxial with the mounting hole on the valve cover. Afterward, the three-jaw chuck B disengages from the sealing sleeve, and the pressing mechanism presses the sealing sleeve into the mounting hole of the valve cover. The clamping and fixing of the valve cover and sealing sleeve by the three-jaw chuck A and B ensures their coaxiality during assembly, reduces wear on the sealing sleeve during pressing, and is convenient and highly practical.

[0005] Preferably, the moving mechanism includes an electric slide rail A, a lifting slider, a connecting plate, an electric turntable, and a rotating shaft. The electric slide rail A is fixedly mounted on a support plate, and the lifting slider is mounted on the electric slide rail A. The electric slide rail A is used to raise and lower the lifting slider. The connecting plate is fixedly mounted on the front end of the lifting slider, the electric turntable is fixedly mounted on the lower end of the connecting plate, and the rotating shaft is mounted on the rotating end of the lower part of the electric turntable. A three-jaw chuck B is fixedly mounted on the lower end of the rotating shaft. After the sealing sleeve is clamped and fixed by the three-jaw chuck B, the electric slide rail A is opened. The electric slide rail A, through the lifting slider, causes the connecting plate to drive the electric turntable and the rotating shaft to descend, thereby causing the three-jaw chuck B to drive the sealing sleeve to descend, so that the lower part of the sealing sleeve enters the mounting hole of the valve cover. Then, the three-jaw chuck B is released, and then the three-jaw chuck B is raised, so that the three-jaw chuck B is disengaged from the upper end of the sealing sleeve. Then, the sealing sleeve is pressed into the mounting hole of the valve cover by a pressing mechanism. This facilitates the adjustment of the height of the sealing sleeve.

[0006] Preferably, the oiling mechanism includes an oil storage tank, a delivery pump, a delivery hose, a nozzle, a vertical plate, a hydraulic cylinder, and a push rod. The oil storage tank is fixedly installed on the upper part of the base plate, the delivery pump is installed on the base plate, the input end of the delivery pump is connected to the oil storage tank, and the output end of the delivery pump is connected to the nozzle through the delivery hose. The nozzle is located on the left side of the three-jaw chuck B. The vertical plate is fixedly installed on the support plate, the hydraulic cylinder is fixedly installed on the left end of the vertical plate, and the push rod is slidably installed on the vertical plate. The left end of the push rod is connected to the output end of the hydraulic cylinder, and the nozzle is fixedly installed on the right end of the push rod. After the sealing sleeve is clamped and fixed by the three-jaw chuck B, the sealing sleeve is then... Before placing the sealing sleeve onto the valve cover, first adjust the height of the sealing sleeve to match that of the nozzle. Then, open the hydraulic cylinder, which moves the nozzle to the right via a push rod until the distance between the nozzle and the sealing sleeve is suitable for oil spraying. Next, turn on the delivery pump, allowing the lubricating oil stored in the oil tank to be sprayed sequentially onto the surface of the sealing sleeve via the delivery pump, delivery hose, and nozzle. Simultaneously, turn on the electric turntable, which rotates the sealing sleeve via a shaft. During rotation, the nozzle evenly sprays lubricating oil onto the surface of the sealing sleeve, facilitating the pressing of the sealing sleeve onto the valve cover and reducing wear during pressing.

[0007] Preferably, the pressing mechanism includes a fixed plate, a cylinder, a lifting rod, a pressure plate, and a translation mechanism. The fixed plate is mounted on the base plate via the translation mechanism, which is used to move the fixed plate left and right. The cylinder is fixedly mounted on the upper part of the fixed plate, and the lifting rod is slidably mounted on the fixed plate up and down. The upper end of the lifting rod is connected to the output end of the cylinder, and the pressure plate is fixedly mounted on the lower end of the lifting rod. When the lower part of the sealing sleeve is placed into the mounting hole of the valve cover by the three-jaw chuck B, the three-jaw chuck B is raised. Then, the translation mechanism causes the fixed plate to move the lifting rod and the pressure plate to the left until the pressure plate moves above the sealing sleeve. After that, the cylinder is opened, and the cylinder lowers the pressure plate via the lifting rod until the pressure plate contacts the sealing sleeve. The pressure plate then presses the sealing sleeve into the mounting hole of the valve cover, thus facilitating the pressing of the sealing sleeve.

[0008] Preferably, the translation mechanism includes an electric slide rail B and a sliding block. The electric slide rail B is fixedly installed on the base plate, and the sliding block is installed on the electric slide rail B. The electric slide rail B is used to move the sliding block left and right. A fixed plate is fixedly installed on the upper end of the sliding block. When moving the fixed plate left and right, the electric slide rail B is opened, and the electric slide rail B moves the fixed plate in the left and right direction through the sliding block. This facilitates the left and right movement of the fixed plate.

[0009] Preferably, it also includes a collection box and an oil drain pipe. The collection box is fixedly installed on the upper part of the base plate, and the three-jaw chuck A is fixedly installed inside the collection box. An oil drain pipe is provided on the collection box, and a valve is provided on the oil drain pipe. With the above configuration, when applying oil to the surface of the sealing sleeve, the falling lubricating oil falls into the collection box and is collected, preventing the lubricating oil from flowing everywhere.

[0010] Preferably, the oil storage tank is equipped with a level gauge; this facilitates the monitoring of the lubricating oil level in the oil storage tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by clamping and fixing the valve cover and sealing sleeve with three-jaw chuck A and three-jaw chuck B, the coaxiality of the valve cover and sealing sleeve during assembly is ensured, the wear of the sealing sleeve during press fitting is reduced, and it is convenient to use and highly practical.

Detailed Implementation

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0019] like Figures 1 to 5The pneumatic regulating valve assembly centering positioner of this utility model includes a base plate 1, a support plate 2, a three-jaw chuck A3, a three-jaw chuck B4, a moving mechanism, an oiling mechanism, and a pressing mechanism. The support plate 2 is fixedly installed on the upper end of the base plate 1. The three-jaw chuck B4 is located above the three-jaw chuck A3 and is coaxial with the three-jaw chuck A3. The oiling mechanism is installed on the base plate 1 and has an oiling function. The three-jaw chuck B4 is installed on the moving mechanism and has a lifting function. The pressing mechanism is installed on the base plate 1 and has a pressing function. When assembling the sealing sleeve 26 into the mounting hole of the valve cover 25, the valve cover 25 is first clamped and fixed by the three-jaw chuck A3, and then the upper part of the sealing sleeve 26 is clamped and fixed by the three-jaw chuck B4. Since both the three-jaw chuck A3 and the three-jaw chuck B4 have a centering function, and the three-jaw chucks... Chuck A3 and three-jaw chuck B4 are coaxial, so at this time, the valve cover 25 and the sealing sleeve 26 are coaxial, and the mounting hole on the valve cover 25 is coaxial with the valve cover 25. Then, the moving mechanism causes the three-jaw chuck B4 to drive the sealing sleeve 26 down, so that the lower part of the sealing sleeve 26 enters the mounting hole on the upper part of the valve cover 25. The three-jaw chuck B4 ensures that the sealing sleeve 26 is in a vertical state and that the sealing sleeve 26 is coaxial with the mounting hole on the valve cover 25. Then, the three-jaw chuck B4 is disengaged from the sealing sleeve 26, and then the pressing mechanism presses the sealing sleeve 26 into the mounting hole of the valve cover 25. The clamping and fixing of the valve cover 25 and the sealing sleeve 26 by the three-jaw chuck A3 and the three-jaw chuck B4 ensures the coaxiality of the valve cover 25 and the sealing sleeve 26 during assembly, reduces the wear of the sealing sleeve 26 during pressing, and is convenient to use and highly practical.

[0020] like Figure 1 and Figure 4 The moving mechanism includes an electric slide rail A5, a lifting slider 6, a connecting plate 7, an electric turntable 8, and a rotating shaft 9. The electric slide rail A5 is fixedly mounted on the support plate 2, and the lifting slider 6 is mounted on the electric slide rail A5. The electric slide rail A5 is used to lift and lower the lifting slider 6. The connecting plate 7 is fixedly mounted on the front end of the lifting slider 6, the electric turntable 8 is fixedly mounted on the lower end of the connecting plate 7, and the rotating shaft 9 is mounted on the rotating end of the lower part of the electric turntable 8. A three-jaw chuck B4 is fixedly mounted on the lower end of the rotating shaft 9. After the sealing sleeve 26 is clamped and fixed by the three-jaw chuck B4... Open the electric slide rail A5. The electric slide rail A5, through the lifting slider 6, causes the connecting plate 7 to drive the electric turntable 8 and the rotating shaft 9 to descend, which in turn causes the three-jaw chuck B4 to drive the sealing sleeve 26 to descend, so that the lower part of the sealing sleeve 26 enters the mounting hole of the valve cover 25. Then, release the three-jaw chuck B4 and then raise the three-jaw chuck B4, so that the three-jaw chuck B4 is no longer in contact with the upper end of the sealing sleeve 26. Then, the sealing sleeve 26 is pressed into the mounting hole of the valve cover 25 by the pressing mechanism. This facilitates the adjustment of the height of the sealing sleeve 26.

[0021] like Figure 1and Figure 3 The oiling mechanism includes an oil storage tank 10, a delivery pump 11, a delivery hose 12, a nozzle 13, a vertical plate 14, a hydraulic cylinder 15, and a push rod 16. The oil storage tank 10 is fixedly installed on the upper end of the base plate 1. The delivery pump 11 is installed on the base plate 1, with its input end connected to the oil storage tank 10 and its output end connected to the nozzle 13 via the delivery hose 12. The nozzle 13 is located to the left of the three-jaw chuck B4. The vertical plate 14 is fixedly installed on the support plate 2. The hydraulic cylinder 15 is fixedly installed on the left end of the vertical plate 14. The push rod 16 is slidably installed on the vertical plate 14, with its left end connected to the output end of the hydraulic cylinder 15. The nozzle 13 is fixedly installed on the right end of the push rod 16. After the sealing sleeve 26 is clamped and fixed by the three-jaw chuck B4, the sealing sleeve 26 is then... Before placing the sealing sleeve 26 onto the valve cover 25, first adjust the sealing sleeve 26 to be at the same height as the nozzle 13. Then, open the hydraulic cylinder 15. The hydraulic cylinder 15 moves the nozzle 13 to the right through the push rod 16 until the distance between the nozzle 13 and the sealing sleeve 26 is suitable for oil spraying. Then, open the delivery pump 11 so that the lubricating oil stored in the oil tank 10 is sprayed onto the surface of the sealing sleeve 26 through the delivery pump 11, delivery hose 12 and nozzle 13 in sequence. At the same time, open the electric turntable 8. The electric turntable 8 rotates the sealing sleeve 26 through the rotating shaft 9. During the rotation, the lubricating oil is evenly sprayed onto the surface of the sealing sleeve 26 by the nozzle 13, which facilitates the pressing of the sealing sleeve 26 onto the valve cover 25 and reduces wear during pressing.

[0022] like Figure 1 and Figure 5 The pressing mechanism includes a fixed plate 17, a cylinder 18, a lifting rod 19, a pressure plate 20, and a translation mechanism.

The lifting rod 19 is slidably mounted on the fixed plate 17, with its upper end connected to the output end of the cylinder 18. The pressure plate 20 is fixedly mounted on the lower end of the lifting rod 19. When the sealing sleeve 26 is pressed by the three-jaw chuck B4... After the lower part is inserted into the mounting hole of the valve cover 25, the three-jaw chuck B4 is raised. Then, the fixed plate 17 moves to the left along with the lifting rod 19 and the pressure plate 20 through the translation mechanism until the pressure plate 20 moves above the sealing sleeve 26. Then, the cylinder 18 is opened, and the cylinder 18 lowers the pressure plate 20 through the lifting rod 19 until the pressure plate 20 contacts the sealing sleeve 26. The sealing sleeve 26 is then pressed into the mounting hole of the valve cover 25 by the pressure plate 20, which facilitates the pressing of the sealing sleeve 26.

[0023] like Figure 5The translation mechanism includes an electric slide rail B21 and a sliding block 22. The electric slide rail B21 is fixedly mounted on the base plate 1, and the sliding block 22 is mounted on the electric slide rail B21. The electric slide rail B21 is used to move the sliding block 22 left and right. A fixed plate 17 is fixedly mounted on the upper end of the sliding block 22. When moving the fixed plate 17 left and right, the electric slide rail B21 is opened, and the electric slide rail B21 moves the fixed plate 17 in the left and right direction via the sliding block 22, thus facilitating the left and right movement of the fixed plate 17. A level gauge is installed on the oil storage tank 10. Example 2
