Description

Technical Field

[0001] The present invention relates to the technical field of automatic welding of pressure gauges, and more specifically to an automatic welding device and process for pressure gauges. Background Art

[0002] As an outstanding representative of modern industrial automation, the pressure gauge automatic welding device integrates mechanical, electrical, control and advanced welding technologies, and is designed to realize the automation, intelligence and efficiency of pressure gauge joint welding. This advanced device not only greatly reduces the dependence on manual welding, but also significantly improves the accuracy and efficiency of welding through its precise control system and efficient welding technology.

[0003] In many industries such as pressure gauge manufacturing, petrochemicals, machinery manufacturing, and electric power, pressure gauge automated welding devices have been widely used, providing these industries with efficient, stable, and reliable welding solutions. Compared with the traditional manual welding method that requires a long period of training, this automated device greatly shortens the processing cycle and improves production efficiency. At the same time, traditional welding devices often produce weld nodules at the weld after welding. These tiny metal nodules not only affect the appearance, but are also likely to reduce the strength and effective cross-sectional area of ​​the pressure gauge due to the inability to completely fuse with the parent material or the previous weld, thereby affecting its overall quality. In view of this, we propose an automated welding device and process for pressure gauges. Summary of the invention

[0023] A welding process for a pressure gauge automatic welding device includes the following process flow:

[0024] S1. When in use, the clamp fixes the position of the pressure gauge, and the side to be welded needs to correspond to the position of the butt joint. At this time, the motor and the air pump are started, the air pump pushes the butt joint to contact the pressure gauge, and the welding head is started through the external controller, and the motor drives the butt joint to rotate to complete the welding process of the pressure gauge housing;

[0025] S2. When welding the pressure gauge, the air pump needs to be started and the motor needs to be driven to rotate the welding assembly clockwise. At this time, the gas discharged from the air pump will enter the first connecting pipe and the second connecting pipe along the pipeline assembly, and then enter the expansion joint along the branch pipe. By pushing the expansion joint to extend, the welder is driven to contact the pressure gauge to achieve welding on one side of the pressure gauge. After welding, the motor needs to be driven in the reverse direction by the external controller. Through the reverse operation of the motor, the driving pipe drives the second adjustment blocks to adjust the position of the first adjustment block, and the second elastic expansion rod quickly resets the position;

[0026] S2.1. When welding the pressure gauge, the air pump needs to be started and the motor needs to be driven to rotate clockwise. At this time, the vertical surface of one side block of the joint will be connected with the vertical surface in the joint groove, so that the joint drives the joint groove to rotate. At this time, the motor will synchronously drive the two fixed plates to rotate. The gas discharged by the air pump will enter the first connecting pipe and the second connecting pipe along the pipeline assembly, and then enter the expansion joint along the branch pipe, so that the pressure in the sliding sleeve increases and pushes the piston plate and the sliding rod to drive the welder to move, so that the welder fits the surface of the pressure gauge;

[0027] S2.2. After welding is completed, the motor needs to be driven in reverse by an external controller. The reverse operation of the motor makes the inclined surfaces of the first adjusting block contact with the second adjusting block. At this time, the second adjusting block will push the first adjusting block to move through its own inclined surface during rotation. Since the first adjusting block is connected to the sealing telescopic sleeve through the support plate, and the air pressure inside the sealing telescopic sleeve is greater than the power when the support plate moves, the support plate drives the sealing telescopic sleeve to move to the left as a whole. At this time, the impact head will contact one side of the pressure gauge. When the first adjusting block is separated from the second adjusting block, the second elastic telescopic rod will drive the sealing telescopic sleeve to reset, and so on.

[0028] S3. Since the mounting block is connected to the slide bar, when the slide bar moves, the positioning plate will move closer to the pressure gauge synchronously with the movement of the slide bar. At this time, the sealed telescopic sleeve gradually extends, and the branch pipe will continue to inject air into the sealed telescopic sleeve to ensure the air pressure in the sealed telescopic sleeve. When the second adjusting block is used to push the first adjusting block and the support plate to move, the air pressure in the sealed telescopic sleeve causes the support plate to push the sealed telescopic sleeve to move as a whole, while driving the impact rod and the impact block to move quickly through the support plate.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention designs a welding assembly, a motor, a pipeline assembly and a branch pipe. When welding the pressure gauge, the air pump needs to be started and the motor needs to be driven to rotate clockwise to drive the welding assembly to rotate. At this time, the gas discharged by the air pump will enter the first connecting pipe and the second connecting pipe along the pipeline assembly, and then enter the telescopic device along the branch pipe, and the welder is driven to contact with the pressure gauge by pushing the telescopic device to extend, so as to achieve welding on one side of the pressure gauge. After welding, the motor needs to be reversely driven by an external controller. Through the reverse operation of the motor, the driving pipe drives several second adjusting blocks to adjust the position of the first adjusting block, and the second elastic telescopic rod quickly resets the device, so that the device only needs to control the welding of the pressure gauge by the forward driving motor and the reverse driving motor, and the cleaning of the weld nodules after welding is completed, which reduces the difficulty of using the device. At the same time, it can save a lot of resources and time for training electric welders, thereby improving the production efficiency of the device.

[0031] 2. The present invention also designs a docking assembly and a pipeline assembly. When welding the pressure gauge, it is necessary to start the air pump and drive the motor to rotate clockwise. At this time, the vertical surface of one side block of the docking joint will dock with the vertical surface in the docking groove, so that the docking joint drives the docking groove to rotate. At this time, the motor will synchronously drive the two fixed plates to rotate, and the gas discharged by the air pump will enter the first connecting pipe and the second connecting pipe along the pipeline assembly, and then enter the telescopic device along the branch pipe, so that the pressure in the sliding sleeve increases and pushes the piston plate and the sliding rod to drive the welder to move, so that the welder is attached to the surface of the pressure gauge, ensuring that the device can attach the welder to the surface of the pressure gauge by controlling the air pump during operation, thereby ensuring the welding effect. At the same time, the motor can complete the welding of the pressure gauge by rotating 180 degrees at a low speed, thereby reducing the difficulty of using the device.

[0032] 3. The present invention also designs an adjusting component, an impactor and an adjusting component. After welding is completed, the motor needs to be driven in reverse by an external controller. The reverse operation of the motor makes the first adjusting block contact the inclined surface of the second adjusting block. At this time, the second adjusting block will push the first adjusting block to move through its own inclined surface during rotation. Since the first adjusting block is connected to the sealing telescopic sleeve through a support plate, and the air pressure inside the sealing telescopic sleeve at this time is greater than the power when the support plate moves, the support plate drives the sealing telescopic sleeve to move to the left as a whole. At this time, the impact head will contact one side of the pressure gauge. When the first adjusting block is separated from the second adjusting block, the second elastic telescopic rod will drive the sealing telescopic sleeve to reset, and so on. After the device is operated to weld the pressure gauge, the impact head repeatedly hits the pressure gauge to clean the weld nodules remaining after the pressure gauge is welded, so as to avoid the pressure gauge being unable to be completely fused with the parent material or the previous weld due to the residual weld nodules, thereby reducing the strength and effective cross-sectional area of ​​the pressure gauge, thereby ensuring the quality of the pressure gauge welded by the device.

[0052] like Figures 1 to 9 As shown, the present invention relates to an automatic welding device and process for a pressure gauge, comprising:

[0053] The housing mechanism 1 includes a base 101, a holder 102 disposed above the base 101, a pressure gauge 103 located in the holder 102, a positioning frame 104, an air pump 105, a motor 106 and a support frame 107, wherein the air pump 105 and the motor 106 are both disposed outside the positioning frame 104, and the support frame 107 is located above the base 101; and the welding mechanism 2 includes a pipeline assembly 201, an adjustment assembly 203 connected to the pipeline assembly 201, a docking assembly 206, The first regulating block 207 and the welding assembly 208, wherein one side of the regulating assembly 203 is connected to one side of the docking assembly 206, the first regulating block 207 is connected to the regulating assembly 203, and the welding assembly 208 is connected to one side of the docking assembly 206. By designing the welding assembly 208, the motor 106, the pipeline assembly 201 and the branch pipe 209, when welding the pressure gauge 103, the air pump 105 needs to be started and the motor 106 needs to be driven to rotate the welding assembly 208 clockwise. At this time, the air pump The gas discharged from 105 will enter the first connecting pipe 202 and the second connecting pipe 205 along the pipeline assembly 201, and then enter the telescopic device 208-4 along the branch pipe 209, and drive the welder 208-5 to contact the pressure gauge 103 by pushing the telescopic device 208-4 to extend, so as to achieve welding on one side of the pressure gauge 103. After welding, the motor 106 needs to be reversely driven by the external controller. Through the reverse operation of the motor 106, the driving pipe 201-1 drives several second adjustment blocks 203-3 to adjust the position of the first adjustment block 207, and quickly resets under the action of the second elastic telescopic rod 208-602, so that the device only needs to control the welding of the pressure gauge 103 by the forward driving motor 106 and the reverse driving motor 106, and the cleaning of the weld nodules after welding is completed, which reduces the difficulty of using the device. At the same time, it can save a lot of resources and time for training electric welders, thereby improving the production efficiency of the device.

[0054] In the embodiment of the present invention, the upper part of the base 101 is fixedly connected to the lower part of the clamp 102, the clamp 102 is clamped with a pressure gauge 103, the upper part of the base 101 is tightly welded to the bottom ends of the positioning frame 104 and the support frame 107, one side of the positioning frame 104 is fixedly connected to the motor 106, one side of the positioning frame 104 is provided with an air pump 105, the air pump 105 is connected to the positioning frame 104, the pipeline assembly 201 is connected to the two first connecting pipes 202, and the two first connecting pipes 202 are respectively connected to the two second connecting pipes 205 through the telescopic pipe 204, and the two second connecting pipes The other end of 205 is connected to the same welding assembly 208, one end of the pipeline assembly 201 is connected to the adjustment assembly 203, the adjustment assembly 203 and the docking assembly 206 are mutually engaged, the other end of the docking assembly 206 is connected to the welding assembly 208, the first adjustment block 207 is arranged in the welding assembly 208, and two branch pipes 209 are arranged outside the welding assembly 208.

By designing the docking assembly 206 and the pipeline assembly 201, when welding the pressure gauge 103, it is necessary to start the air pump 105 and drive the motor 106 to rotate clockwise. At this time, the vertical surface of one side block of the docking joint 203-5 will be connected with the vertical surface in the docking groove 206-3, so that the docking joint 203-5 drives the docking groove 206-3 to rotate. At this time, the motor 106 will synchronously drive the two fixed plates 208-3 to rotate, and the gas discharged from the air pump 105 will enter the first connecting pipe 202 and the second connecting pipe 205 along the pipeline assembly 201. Then, it will enter the telescopic device 208-4 along the branch pipe 209, so that the pressure in the sleeve 208-401 increases and pushes the piston plate 208-403 and the slide rod 208-402 to drive the welder 208-5 to move, so that the welder 208-5 is attached to the surface of the pressure gauge 103, ensuring that the device can attach the welder 208-5 to the surface of the pressure gauge 103 only by controlling the air pump 105 during operation, thereby ensuring the welding effect. At the same time, the motor 106 can complete the welding of the pressure gauge 103 by rotating 180 degrees at a low speed, thereby reducing the difficulty of using the device.

[0055] In an embodiment of the present invention, the pipeline assembly 201 includes a driving tube 201-1, and two limiting grooves 201-2 are provided outside the driving tube 201-1, and the two limiting grooves 201-2 are both annular. The limiting sleeve 201-3 is connected to the driving tube 201-1, and the limiting sleeve 201-3 is slidably connected in the two limiting grooves 201-2. A plurality of through holes 201-4 are provided outside the driving tube 201-1, and the limiting sleeve 201-3 is connected to the driving tube 201-1 through the plurality of through holes 201-4. The limiting sleeve 201-3 is connected to the opposite ends of the two first connecting tubes 202, and the first connecting tubes 202 are respectively located above and below the limiting sleeve 201-3. One end of the driving tube 201-1 is connected to the support frame 107 The end of the driving tube 201-1 connected to the support frame 107 is connected to the motor 106 for transmission, and the other end of the driving tube 201-1 is connected to the adjusting component 203 for transmission. The adjusting component 203 includes a first elastic telescopic rod 203-1, one end of the first elastic telescopic rod 203-1 is fixedly connected to the docking joint 203-5, one end of the docking joint 203-5 is provided with a plurality of blocks with arc surfaces and vertical surfaces, the first elastic telescopic rod 203-1 is fixedly connected to a plurality of fixing frames 203-2, the fixing frames 203-2 are fixedly connected to a second adjusting block 203-3, one side of the second adjusting block 203-3 is provided with an inclined surface 203-4, the first adjusting block 207 and the second adjusting block 203-3 overlap each other, and the first elastic telescopic rod 20 One end of 3-1 passes through the support frame 107 and is connected to the drive tube 201-1 for transmission, and the docking joint 203-5 is clamped in the docking assembly 206. By designing the adjustment assembly 203, the impactor 208-6 and the adjustment assembly 203, after welding, the motor 106 needs to be driven in the reverse direction by the external controller. Through the reverse operation of the motor 106, the first adjustment block 207 is in contact with the inclined surface 203-4 of the second adjustment block 203-3. At this time, the second adjustment block 203-3 will push the first adjustment block 207 to move through its own inclined surface 203-4 during rotation. Since the first adjustment block 207 is connected to the sealed telescopic sleeve 208-607 through the support plate 208-608, and the air pressure inside the sealed telescopic sleeve 208-607 is greater than the support plate 208-608, the air pressure inside the sealed telescopic sleeve 208-607 is greater than the support plate 208-608. The power of the support plate 208-608 during movement causes the support plate 208-608 to drive the sealing telescopic sleeve 208-607 to move to the left as a whole. At this time, the impact head 208-7 will contact one side of the pressure gauge 103. When the first adjustment block 207 is separated from the second adjustment block 203-3, the second elastic telescopic rod 208-602 will drive the sealing telescopic sleeve 208-607 to reset, and so on. After the pressure gauge 103 is welded, the device can clean the residual weld nodules of the pressure gauge 103 by repeatedly impacting the pressure gauge 103 with the impact head 208-7, so as to avoid the pressure gauge 103 from being completely fused with the parent material or the previous weld due to the residual weld nodules, thereby reducing the strength and effective cross-sectional area of ​​the pressure gauge 103.This ensures the quality of the welding pressure gauge 103 of the device.

[0056] As another embodiment of the present invention, the docking assembly 206 includes a drive shaft 206-1, one end of the drive shaft 206-1 is fixedly connected to the docking shell 206-2, a docking groove 206-3 is provided in the docking shell 206-2, the shape of the docking groove 206-3 is adapted to the shape of a plurality of blocks with arc surfaces and vertical surfaces provided on the outside of the docking head 203-5, the other end of the drive shaft 206-1 is transmission-connected to the welding assembly 208, the welding assembly 208 includes a sealing cylinder 208-1, one side of the sealing cylinder 208-1 is clamped with a sealing strip 208-2, and the sealing strip 208-2 is connected to the sealing cylinder 208-1. The upper and lower parts of the sealing cylinder 208-1 are respectively connected with the two fixing plates 208-3, and one side of the two fixing plates 208-3 is fixedly connected with a retractor 208-4, and the other end of the retractor 208-4 is provided with a welder 208-5, and a striker 208-6 is provided below the retractor 208-4, and one end of the striker 208-6 is fixedly connected with the impact head 208-7, and the fixing plate 208-3 is respectively connected with the retractor 208-4 and the striker 208-6 through the branch pipe 209, and the sealing strip 208-2 is connected with the corresponding ends of the two second connecting pipes 205 Since the mounting block 208-601 is connected to the slide bar 208-402, when the slide bar 208-402 moves, the positioning plate 208-603 will move closer to the pressure gauge 103 with the movement of the slide bar 208-402. At this time, the sealing telescopic sleeve 208-607 gradually extends, and the branch pipe 209 will continue to inject air into the sealing telescopic sleeve 208-607 to ensure the air pressure in the sealing telescopic sleeve 208-607. When the reverse rotation pushes the first adjusting block 207 and the support plate 208-608 to move through the second adjusting block 203-3, the sealing telescopic sleeve 208 -607, the air pressure inside the support plate 208-608 pushes the sealing telescopic sleeve 208-607 to move as a whole, and at the same time drives the impact rod 208-604 and the impact block to move quickly through the support plate 208-608, ensuring that the impact head 208-7 can move synchronously with the movement of the welder 208-5, avoiding the difficulty in cleaning the weld nodules on the surface of the pressure gauge 103 due to the long distance during the reciprocating movement of the impact head 208-7 driven by the first adjustment block 207 and the second adjustment block 203-3, and the above steps are all completed when the air pump 105 is running, thereby reducing the difficulty of using the device;

[0057] By setting a sealing strip 208-2 outside the sealing cylinder 208-1, and the sealing strip 208-2 is in a circular shape, when the sealing cylinder 208-1 and the fixed plate 208-3 rotate, the sealing strip 208-2 will always remain in place with the first connecting tube 202 and the second connecting tube 205, avoiding affecting the air pump 105 to inject gas into the sealing cylinder 208-1 during the rotation process.

[0058] As another embodiment of the present invention, the telescope 208-4 includes a sleeve 208-401, a slide rod 208-402 is slidably connected in the sleeve 208-401, one end of the slide rod 208-402 is fixedly connected to the side corresponding to the piston plate 208-403, and the other side of the piston plate 208-403 is fixedly connected to a spring 208-404, the shape of the piston plate 208-403 is adapted to the shape of the inner wall of the sleeve 208-401, the other end of the spring 208-404 is fixedly connected to the inner wall of the sleeve 208-401, the sleeve 208-401 is fixedly connected to one side of the fixed plate 208-3, and the sleeve 208-4 01 is connected with one end corresponding to the branch pipe 209 through the fixing plate 208-3, the other end of the sliding rod 208-402 is fixedly connected with the welding device 208-5, the sliding sleeve 208-401 and the bottom of the sliding rod 208-402 are connected with the impactor 208-6, the impactor 208-6 includes a mounting block 208-601, one side of the mounting block 208-601 is fixedly connected with one end corresponding to the second elastic telescopic rod 208-602, the other end of the second elastic telescopic rod 208-602 is fixedly connected with the positioning plate 208-603, the positioning plate 208-603 is fixedly connected to the outside of the impact rod 208-604, and the impact rod 208 -604 is slidably connected in the sleeve 208-605, and the sleeve 208-605 is fixedly connected with a positioning block 208-606. One side of the positioning plate 208-603 is fixedly connected to the sealing telescopic sleeve 208-607, and the other side of the sealing telescopic sleeve 208-607 is fixedly connected to the support plate 208-608. The sealing telescopic sleeve 208-607 is connected to one end of the branch pipe 209, and the other side of the support plate 208-608 is fixedly connected to the first adjustment block 207. The mounting block 208-601 is fixedly connected to the bottom of the sliding rod 208-402, and the positioning block 208-606 is fixedly connected to the sliding sleeve 208-4 01, the other end of the impact rod 208-604 is fixedly connected to the impact head 208-7. Because a plurality of through holes 201-4 and a limiting sleeve 201-3 are arranged outside the driving shaft 206-1, when the driving shaft 206-1 rotates, the limiting sleeve 201-3 will keep the same position in the limiting sleeve 208-401. On the one hand, the setting of the limiting sleeve 201-3 can avoid affecting the rotation of the driving shaft 206-1. On the other hand, the limiting sleeve 201-3 can ensure that the driving shaft 206-1 can always be connected with the first connecting pipe 202 and the second connecting pipe 205 to avoid gas leakage.

[0059] The first connecting tube 202 and the second connecting tube 205 are docked together through the telescopic tube 204, so that when the docking joint 203-5 and the docking groove 206-3 are in arc contact, the docking joint 203-5 can squeeze the docking joint 203-5 and the first elastic telescopic rod 203-1 to extend and contract. At this time, the telescopic tube 204 can extend or contract with the deformation of the first elastic telescopic rod 203-1, thereby ensuring the connection effect between the first connecting tube 202 and the second connecting tube 205.

[0060] Working principle: This embodiment provides an automatic welding device and process for a pressure gauge. When in use, the clamp 102 fixes the position of the pressure gauge 103, and the side to be welded needs to correspond to the position of the docking joint 203-5. At this time, the motor 106 and the air pump 105 are started, and the docking joint 203-5 is pushed to contact the pressure gauge 103 by the air pump 105 and the welding head is started by the external controller, and the docking joint 203-5 is driven to rotate by the motor 106 to complete the welding process of the outer shell of the pressure gauge 103;

[0061] When welding the pressure gauge 103, the air pump 105 needs to be started and the motor 106 needs to be driven to rotate the welding assembly 208 clockwise. At this time, the gas discharged from the air pump 105 will enter the first connecting pipe 202 and the second connecting pipe 205 along the pipeline assembly 201, and then enter the telescopic device 208-4 along the branch pipe 209, and drive the welder 208-5 to contact the pressure gauge 103 by pushing the telescopic device 208-4 to extend, so as to achieve welding on one side of the pressure gauge 103. After welding, the motor 106 needs to be driven in the reverse direction by the external controller. Through the reverse operation of the motor 106, the driving pipe 201-1 drives the second adjustment blocks 203-3 to adjust the position of the first adjustment block 207, and the second elastic telescopic rod 208-602 quickly resets the position;

[0062] When welding the pressure gauge 103, the air pump 105 needs to be started and the motor 106 needs to be driven to rotate clockwise. At this time, the vertical surface of one side of the docking joint 203-5 will be connected with the vertical surface in the docking groove 206-3, so that the docking joint 203-5 drives the docking groove 206-3 to rotate. At this time, the motor 106 will synchronously drive the two fixed plates 208-3 to rotate, and the gas discharged by the air pump 105 will enter the first connecting pipe 202 and the second connecting pipe 205 along the pipeline assembly 201, and then enter the expansion joint 208-4 along the branch pipe 209, so that the pressure in the sliding sleeve 208-401 increases and pushes the piston plate 208-403 and the sliding rod 208-402 to drive the welder 208-5 to move, so that the welder 208-5 fits the surface of the pressure gauge 103;

[0063] After welding is completed, the motor 106 needs to be driven in reverse by the external controller. The reverse operation of the motor 106 makes the first adjustment block 207 contact with the inclined surface 203-4 of the second adjustment block 203-3. At this time, the second adjustment block 203-3 will push the first adjustment block 207 to move through its own inclined surface 203-4 during rotation. Since the first adjustment block 207 is connected to the sealed telescopic sleeve 208-607 through the support plate 208-608, and the air pressure inside the sealed telescopic sleeve 208-607 is greater than the power when the support plate 208-608 moves, the support plate 208-608 drives the sealed telescopic sleeve 208-607 to move to the left as a whole. At this time, the impact head 208-7 will contact one side of the pressure gauge 103. When the first adjustment block 207 is separated from the second adjustment block 203-3, the second elastic telescopic rod 208-602 will drive the sealed telescopic sleeve 208-607 to reset, and so on.

[0064] Since the mounting block 208-601 is connected to the slide bar 208-402, when the slide bar 208-402 moves, the positioning plate 208-603 will move closer to the pressure gauge 103 synchronously with the movement of the slide bar 208-402. At this time, the sealed telescopic sleeve 208-607 gradually extends, and the branch pipe 209 will continue to inject air into the sealed telescopic sleeve 208-607 to ensure the air pressure in the sealed telescopic sleeve 208-607. When the reverse rotation pushes the first adjusting block 207 and the support plate 208-608 to move through the second adjusting block 203-3, due to the air pressure in the sealed telescopic sleeve 208-607, the support plate 208-608 pushes the sealed telescopic sleeve 208-607 to move as a whole, while driving the impact rod 208-604 and the impact block to move rapidly through the support plate 208-608.

The motor (106) drives the docking joint (203-5) to rotate, thereby completing the welding process of the outer shell of the pressure gauge (103); S2. When welding the pressure gauge (103), the air pump (105) needs to be started and the motor (106) needs to be driven to rotate the welding assembly (208) clockwise. At this time, the gas discharged from the air pump (105) will enter the first connecting pipe (202) and the second connecting pipe (205) along the pipeline assembly (201), and then enter the telescopic device (208-4) along the branch pipe (209). By pushing the telescopic device (208-4) to extend, the welding device (208-5) is driven to contact the pressure gauge (103), so as to achieve welding on one side of the pressure gauge (103).

2. After welding is completed, the motor (106) needs to be driven in the reverse direction by an external controller. The reverse operation of the motor (106) causes the first adjustment block (207) to contact the inclined surface (203-4) of the second adjustment block (203-3). At this time, the second adjustment block (203-3) will push the first adjustment block (207) to move through its own inclined surface (203-4) during rotation. Since the first adjustment block (207) is connected to the sealing telescopic sleeve (208-607) through the support plate (208-608), and the sealing At this time, the air pressure inside the sealing telescopic sleeve (208-607) is greater than the power of the support plate (208-608) when it moves, so that the support plate (208-608) drives the sealing telescopic sleeve (208-607) to move leftward as a whole.
