[0001] This utility model relates to the field of valve technology, specifically to a valve sealing ring assembly and positioning device. Background Technology

[0002] Some semiconductor vacuum equipment includes a transfer chamber and a process chamber. The transfer chamber is used for wafer transfer, and the process chamber is used for semiconductor processing on the wafer. To prevent the process chamber from being interfered with by the transfer chamber, a vacuum gate valve needs to be installed between the process chamber and the transfer chamber.

[0003] In the existing technology, the design of a valve involves designing grooves (such as dovetail grooves) on a metal base such as an aluminum plate or stainless steel plate, and then designing a sealing ring made of fluororubber or perfluoroether material and installing it on the metal base to form a combined valve. When assembling the valve with the sealing ring, the valve body needs to be fixed in order to facilitate the installation of the sealing structure. However, it is not convenient to fix the valve body during the actual installation process, and the bottom of the valve body may not be completely flat. When fixing the valve body, the valve body is prone to shaking, which affects the assembly of the sealing structure.

[0004] A valve sealing ring assembly and positioning device is proposed to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve sealing ring assembly and positioning device, including a base;

[0007] The base has four pillars symmetrically installed on its top, and a placement plate is fixedly installed on the top of the four pillars.

[0008] Also includes:

[0009] Positioning components are provided at the top and bottom of the placement plate;

[0010] The positioning component includes a vertical plate fixedly installed on one side of the top of the placement plate, and fixed rods are symmetrically installed on one side of the vertical plate. A fixed block is fixedly installed on the end of each of the two fixed rods away from the vertical plate, and the fixed block is fixedly connected to the placement plate.

[0011] Among them, the two fixed rods are slidably connected to the outside of the movable plate, and the other side of the top of the placement plate is provided with a movable groove, and the movable plate is slidably connected to the movable groove. Moreover, the top of the movable plate is symmetrically installed with mounting blocks.

[0012] Preferably, each of the two mounting blocks has a movable rod slidably connected inside, and a positioning plate is fixedly installed at one end of each movable rod. Furthermore, a telescopic spring is sleeved on the outer side of each movable rod, and the two ends of the telescopic spring are fixedly connected to the mounting block and the movable rod, respectively.

[0013] Preferably, the positioning plate is symmetrically rotatably connected to two rotating shafts, and a support frame is rotatably connected to the outer side of each of the two rotating shafts. One end of the support frame is fixedly connected to the positioning plate, and a rotating gear is fixedly installed at the end of the rotating shaft away from the positioning plate.

[0014] Preferably, the movable plate is fixedly mounted with a mounting bracket above each of the two rotating gears, and a toothed plate is fixedly mounted at the bottom of the mounting bracket. The rotating gears are meshed with the toothed plate. A movable ring is slidably connected to the outside of the rotating shaft, and positioning strips are symmetrically installed inside the movable ring. A strip groove is symmetrically opened on both sides of the outside of the rotating shaft, and the positioning strip is slidably connected to the strip groove. A positioning rod is fixedly mounted on the upper outside of the movable ring.

[0015] Preferably, a turntable is rotatably connected to one side of the bottom of the placement plate, and a steel wire rope is fixedly installed on one side of the turntable. The end of the steel wire rope away from the turntable is fixedly connected to the movable plate. Furthermore, a guide wheel is rotatably connected to the bottom of the placement plate on the side of the turntable, and the steel wire rope is rotatably connected to the guide wheel.

[0016] Preferably, a handle is fixedly installed on one side of the turntable, and sliding rods are symmetrically slidably connected inside the handle. A movable frame is fixedly installed on the top of the two sliding rods, and a return spring is sleeved on the lower outer side of each of the two sliding rods. The two ends of the return spring are fixedly connected to the handle and the sliding rod, respectively.

[0017] Preferably, a positioning block is fixedly installed on one side of the top of the mobile frame, and a number of positioning slots are equally spaced on the bottom of the placement plate on one side of the handle, and the positioning block is inserted into the positioning slots.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this valve sealing ring assembly and positioning device facilitates the fixing and positioning of the valve body during the assembly of the valve and the sealing structure. Even if the bottom surface of the valve body is uneven, the valve body can be reliably fixed, avoiding valve body shaking during subsequent assembly and improving practicality. The specific details are as follows:

[0019] 1. When fixing and positioning the valve body before assembly, place the valve body on the placement plate so that one side of the valve body is in contact with the upright plate. Then, move the movable plate so that the positioning plate abuts against the other side of the valve body. Adjust the position of the two movable rings according to the width of the valve body. Continue to move the movable plate until the positioning plate abuts against the valve body and stops moving. This allows the mounting block to slide on the movable rod and stretch the telescopic spring. Then, the toothed plate on the mounting bracket can move to drive the rotating gear to rotate, causing the rotating shaft to rotate. After the rotating shaft rotates, the movable ring can be driven to rotate through the cooperation of the positioning strip and the slot. This causes the positioning rod to rotate and abut against the top of the valve body, which can press down and position the valve body. In addition to positioning the two sides of the valve body, the top of the valve body can also be positioned to prevent the valve body from shaking or tilting due to uneven bottom. This makes it easier to fix and position the valve body when assembling the valve and sealing structure. Even if the bottom surface of the valve body is uneven, it can be reliably fixed to prevent the valve body from shaking during subsequent assembly, thus improving practicality.

[0020] 2. When positioning the valve body, the user simultaneously holds the movable frame and the handle, causing the movable frame to move downwards. This moves the sliding rod, stretching the return spring and disengaging the positioning block from the positioning slot. The turntable then loses its limit position. By rotating the turntable clockwise using the handle, the movable plate can be moved via the wire rope. After the movable plate positions the valve body, the positioning rod aligns with the adjacent positioning slot. Releasing the movable frame allows the return spring to reset the positioning block, inserting it back into the positioning slot to position the turntable. This prevents the movable plate from moving, making it easier to control the rapid movement of the movable plate during valve body positioning, facilitating user operation and improving convenience.

Moreover, the top of the movable plate 204 is symmetrically equipped with mounting blocks 206, which makes it easy to fix and position the valve body when assembling the valve and the sealing structure. Even if the bottom surface of the valve body is uneven, the valve body can be reliably fixed, avoiding the valve body from shaking during subsequent assembly and improving practicality.

[0029] Both mounting blocks 206 have movable rods 207 slidably connected inside, and one end of each movable rod 207 is fixedly mounted with a positioning plate 209. A telescopic spring 208 is sleeved on the outer side of each movable rod 207, and both ends of the telescopic spring 208 are fixedly connected to the mounting block 206 and the movable rod 207 respectively, allowing the mounting block 206 to automatically return to its original position after sliding on the movable rod 207. Rotating shafts 210 are symmetrically rotatably connected to both sides of the positioning plate 209, and a support frame 211 is rotatably connected to the outer side of each rotating shaft 210. One end of the support frame 211 is fixedly connected to the positioning plate 209. A rotating gear 212 is fixedly installed at the end of the rotating shaft 210 away from the positioning plate 209 to support the rotation of the rotating shaft 210.

A toothed plate 214 is fixedly installed at the bottom of the mounting bracket 213, and the rotating gear 212 meshes with the toothed plate 214. A movable ring 215 is slidably connected to the outside of the rotating shaft 210, and positioning strips 216 are symmetrically installed inside the movable ring 215. Slotted grooves 217 are symmetrically formed on both sides of the outside of the rotating shaft 210, and the positioning strips 216 are slidably connected to the slots 217. The movable ring 215... A positioning rod 218 is fixedly installed on the upper exterior, allowing the rotating shaft 210 of the mounting bracket 213 to drive the rotating gear 212 to rotate when it is stationary. A turntable 219 is rotatably connected to one side of the bottom of the placement plate 102, and a steel wire rope 220 is fixedly installed on one side of the turntable 219. The end of the steel wire rope 220 away from the turntable 219 is fixedly connected to the movable plate 204. A guide wheel 221 is rotatably connected to the bottom of the placement plate 102 on the side of the turntable 219, and the steel wire rope 220 is rotatably connected to the guide wheel 221, so that the rotation of the turntable 219 can drive the movable plate 204 to move. A handle 222 is fixedly installed on one side of the turntable 219. Furthermore, the handle 222 is symmetrically connected to the sliding rods 223 inside, and the top of the two sliding rods 223 is fixedly installed with a moving frame 225. Moreover, the lower outer surface of the two sliding rods 223 is fitted with a return spring 224, and the two ends of the return spring 224 are fixedly connected to the handle 222 and the sliding rods 223 respectively, so that the moving frame 225 can automatically return to its original position after moving. A positioning block 226 is fixedly installed on one side of the top of the moving frame 225, and several positioning slots 227 are equidistantly opened on the bottom of the placement plate 102 on one side of the handle 222. The positioning block 226 is inserted into the positioning slot 227 to position the turntable 219.

[0030] Working principle: Before using this type of valve sealing ring assembly positioning device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, when fixing and positioning the valve body before assembly, the valve body is placed on the placement plate 102, so that one side of the valve body is in contact with the upright plate 201. Then, the movable plate 204 can be moved so that the positioning plate 209 abuts against the other side of the valve body. The positions of the two movable rings 215 can be adjusted according to the width of the valve body. Then, the movable plate 204 is moved again until the positioning plate 209 abuts against the valve body and no longer moves, so that the mounting block 206 slides on the movable rod 207 and stretches the telescopic spring 208. Then, the toothed plate 214 on the mounting bracket 213 moves to drive the rotating gear 212 to rotate, so that the rotation... The shaft 210 rotates, and after the shaft 210 rotates, the movable ring 215 rotates through the cooperation of the positioning bar 216 and the strip groove 217, so that the positioning rod 218 rotates and abuts against the top of the valve body, which can press down and position the valve body. In addition, while positioning the two sides of the valve body, the top of the valve body can also be positioned, which can prevent the bottom of the valve body from shaking or tilting due to unevenness. This makes it easier to fix and position the valve body when assembling the valve and the sealing structure. Even if the bottom surface of the valve body is uneven, the valve body can be reliably fixed, which can prevent the valve body from shaking during subsequent assembly and improves practicality.

[0031] When positioning the valve body, the user simultaneously holds the movable frame 225 and the handle 222, causing the movable frame 225 to move downwards. This moves the sliding rod 223, stretching the return spring 224, which in turn disengages the positioning block 226 from the positioning groove 227. This causes the turntable 219 to lose its limit. By rotating the turntable 219 clockwise through the handle 222, the movable plate 204 can be moved by pulling the wire rope 220. After the movable plate 204 positions the valve body, the positioning rod 218 aligns with the adjacent positioning groove 227. Releasing the movable frame 225 allows the positioning block 226 to reset and insert into the positioning groove 227 under the action of the return spring 224, thus positioning the turntable 219. This prevents the movable plate 204 from moving, making it easier to control the rapid movement of the movable plate 204 when positioning the valve body, facilitating user operation and improving convenience.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
