Description

Technical Field

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1 to 4 As shown, a sealing ring assembly device for a high-voltage connector described in an embodiment of the present invention includes a shell 1, the interior of the shell 1 is configured with a stretching component 4 for stretching the sealing ring, and the upper part of the shell 1 is configured with a protective component 3 for preventing the sealing ring from flying off, the stretching component 4 includes a hydraulic lifter 406, an active plate 411 is provided above the hydraulic lifter 406, the protective component 3 includes a sliding plate 301, one end of the sliding plate 301 is slidably connected to the stretching block 302, one end of the active plate 411 is fixedly connected to the stretching block 302, and a rotatable baffle 303 is provided above the sliding plate 301, and the active plate 411 drives the stretching block 302 to move horizontally and vertically at the same time.

[0022] The present invention takes into account that when the sealing ring needs to be installed in the sealing position of the high-pressure connector, the sealing ring is first placed on the outside of the expansion block 302, and then the expansion block 302 is moved to expand the sealing ring. When the sealing ring is expanded, one end of the high-pressure connector is inserted into the middle position of the expansion block 302, and then the hydraulic lifter 406 is started to drive the active plate 411 to move downward. The downward movement of the active plate 411 drives the expansion block 302 to move downward. When the expansion block 302 moves to a certain position, the sealing ring loses the expansion force and resets, and is quickly stuck in the sealing position of the high-pressure connector to complete the installation. However, since the sealing ring has a certain elasticity, the sealing ring will reset instantly after losing the expansion force of the expansion block 302. At this time, the sealing ring is prone to bounce off or tilt and get stuck on the connector surface, and the sealing ring cannot be accurately installed in the sealing position of the high-pressure connector, which will reduce the installation efficiency and quality of the high-pressure connector sealing ring. Therefore, first put the sealing ring on the top of the sliding plate 301 so that it is located outside the expansion block 302 and below the baffle 303. At this time, the active plate 411 drives the expansion block 302 to move outward to expand the sealing ring, which can make the sliding plate 301 move synchronously. The synchronous movement of the sliding plate 301 will drive the baffle 303 to move, so that the baffle 303 is always above the sealing ring. When the expansion block 302 expands the sealing ring to a certain extent, align the sealing position of the high-pressure connector with the expanded sealing ring, and start the hydraulic lifter 406 to drive The active plate 411 moves telescopically, and the movement of the active plate 411 drives the expansion block 302 to move up and down. At this time, the expansion block 302 will gradually separate from the expanded sealing ring. When the expansion block 302 moves a certain distance, the sealing ring will completely separate from it, and thus be stuck in the sealing position of the high-voltage connector, thereby completing the sealing work. At this time, the baffle 303 is always located above the sealing ring, which can prevent the sealing ring from bouncing off under the action of its own elastic force after separating from the expansion block 302, and can effectively improve the installation efficiency and quality of the connector sealing ring.

[0023] like Figures 3 and 4 as well as Figures 8 and 9 As shown, the expansion assembly 4 also includes an electric cylinder 401, and the output end of the electric cylinder 401 is fixedly connected to a moving rod 403, and the surface of the moving rod 403 is rotatably connected to a long rocker arm 408 through a pin shaft inside the connecting block, and the other end of the long rocker arm 408 is rotatably connected to one side of a hydraulic lifter 406 through a pin shaft, and a moving plate 407 is detachably connected to the bottom of the hydraulic lifter 406, and the bottom of the moving plate 407 is slidably connected to the bottom plate 5, and the inner side surface of the moving plate 407 is rotatably connected to a short rocker arm 409, and the other end of the short rocker arm 409 is rotatably connected to a protective shell 402, and the protective shell 402 is fixedly connected to the bottom plate 5, and the bottom surface of the bottom plate 5 is arranged in an arc shape.

[0024] During operation, after the sealing ring is placed above the sliding plate 301, the electric cylinder 401 is started to drive the moving rod 403 to move upward, and the movement of the moving rod 403 drives the long pendulum rod 408 to swing through the pin shaft. When the long pendulum rod 408 swings, it drives the hydraulic lifter 406 and the moving plate 407 to move outward through the pin shaft. Moreover, due to the length movement of the long pendulum rod 408, the swing of the long pendulum rod 408 will push the moving plate 407 to move outward and downward for a distance. At this time, the upper part of the bottom plate 5 is in an arc shape. The movable plate 407 is configured such that when the movable plate 407 slides, it moves from the high point position of the bottom plate 5 to the low point position, thereby preventing the movable plate 407 from being unable to move downward for a certain distance. Furthermore, the movable plate 407 moves outward, driving the active plate 411 to move via the hydraulic lifter 406. The movement of the active plate 411 drives the movement of the opening block 302. The movement of the opening block 302 can open the sealing ring placed on the surface of the sliding plate 301 until it is opened to a certain extent, making it convenient for the high-voltage connector to be inserted into the middle position of the opening block 302. It should be noted that since multiple groups of short rocker arms 409 are provided on the inner side of the movable plate 407, and the other end of the short rocker arm 409 is rotatably connected to the outer surface of the protective shell 402 through a pin shaft, the short rocker arm 409 can move outward more smoothly at this time, so that the hydraulic lifter 406 can move smoothly to drive the expansion block 302 at one end of the active plate 411 to stably expand the sealing ring, further avoiding the sealing ring from bouncing off during the expansion process or during the separation process from the expansion block 302, which can effectively improve the efficiency and quality of installing the sealing ring on the high-voltage connector.

[0025] like Figures 5 to 7 As shown, the protective component 3 also includes a mating plate 304, a push plate 305 is provided on the side of the mating plate 304 close to the support block 302, and pressing springs 306 are provided on both sides of the baffle 303, and the bottom of the pressing spring 306 is slidably connected to the sliding plate 301 through a slider, and the baffle 303 is fixedly connected to the side close to the push plate 305 with a fixed plate 307, and the inclined end of the push plate 305 is higher than the upper surface of the fixed plate 307.

[0026] When the locking cam 303 is in the unlocked position, the locking cam 303 is in the unlocked position, and the locking cam 303 is in the unlocked position, so that the locking cam 303 is unlocked. When the push plate 305 is no longer in contact with the baffle 303, the baffle 303 can be reset under the elastic force of the pressing spring 306. Moreover, since the bottom of the pressing spring 306 can slide, it can avoid the situation where the pressing spring 306 cannot be deformed significantly after being compressed, and cannot provide power for the reset of the baffle 303.

[0027] like Figure 1 and Figures 6 and 7 As shown, a moving block 308 is rotatably connected to the baffle 303 below by a pin shaft, and the moving block 308 is fixedly connected to the sliding plate 301. A slider is fixedly connected to the bottom of the matching plate 304, and a tension spring 309 is provided between the slider and the sliding plate 301. The width of the matching plate 304 is greater than that of the sliding plate 301. A connecting sleeve 2 is slidably connected to the side of the sliding plate 301, and a notch is provided in the connecting sleeve 2 at the sliding position of the sliding plate 301. The connecting sleeve 2 is fixedly connected to the outer shell 1.

[0028] When the locking cam 305 is in the unlocked position, the locking cam 305 is in the unlocked position, and the locking cam 305 is locked. It should be noted that when the baffle 303 flips, the baffle 303 will rotate above the moving block 308. The limit of the moving block 308 can not only limit the flipping range of the baffle 303 and improve the flipping stability, but also prevent the baffle 303 from flipping too large an angle. At this time, the pressing spring 306 cannot reset it smoothly, effectively improving the protection effect of the sealing ring.

[0029] like Figures 2 to 3 As shown, a fixed cylinder 404 is fixedly connected to the top of the moving rod 403, and an extrusion telescopic plate 405 is slidably arranged inside the fixed cylinder 404. Multiple groups of buffer springs 410 are arranged between the bottom surface of the extrusion telescopic plate 405 and the fixed cylinder 404, and the extrusion telescopic plate 405 is set to slide and telescopically.

[0030] When working, after the active plate 411 drives the expansion block 302 to expand the sealing ring to a suitable diameter, the active plate 411 will drive the expansion block 302 to move downward under the drive of the hydraulic lifter 406 after the high-pressure connector is inserted. In order to avoid the expansion block 302 moving downward too quickly and causing the sealing ring to bounce off, an extrusion and telescopic plate 405 is provided directly below the multiple groups of expansion blocks 302. When the expansion block 302 moves downward, it will contact the extrusion and telescopic plate 405, thereby pushing the extrusion and telescopic plate 405 to slide downward inside the fixed cylinder 404. At this time, the buffer spring 410 located between the fixed cylinder 404 and the extrusion and telescopic plate 405 will be squeezed to make the expansion block 302 move downward slowly, which can prevent the hydraulic lifter 406 from starting and quickly driving the expansion block 302 to release the expanded sealing ring, thereby further improving the stability of the sealing ring installation. It should be noted that when the expansion block 302 releases the sealing ring, it will gradually move vertically downward, and the lowered position of the expansion block 302 is fixed, and when the expansion block 302 moves outward, the moving rod 403 will move upward, driving the fixed cylinder 404 to move upward as well. The upward movement of the fixed cylinder 404 drives the internal extrusion and telescopic plate 405 to move upward as well. The upward movement of the extrusion and telescopic plate 405 will shorten the stroke between the expansion block 302, so that the expansion block 302 can not only fully squeeze the multiple groups of buffer springs 410 inside the fixed cylinder 404 when moving downward, but can also quickly contact the extrusion and telescopic plate 405, thereby improving the stability of the sealing ring detaching from the surface of the expansion block 302.

[0031] like Figure 3 As shown, the output end of the electric cylinder 401 is slidably connected to the protective shell 402, the fixed cylinder 404 is set in a shape that is wide at the top and narrow at the bottom, and a heat dissipation port is opened on the surface of the protective shell 402. The electric cylinder 401 can drive the fixed cylinder 404 above the movable rod 403 to move up and down.

[0032] During operation, when the movable plate 407 drives the active plate 411 inside the hydraulic lifter 406 to move outward, the active plate 411 moves and drives the expansion block 302 to move outward to expand the sealing ring. When the push plate 305 on the side of the matching plate 304 is fixed, it pushes the baffle 303 to flip. Since the push plate 305 is fixed, the sealing ring is already in the state of installation. Therefore, the baffle 303 is in the state of flipping and no longer protects the sealing ring. Then the electric cylinder 401 is started to make the movable rod 403 move downward, thereby resetting the expansion block 302. After the angle between the baffle 303 and the fixed plate 307 loses contact with the push plate 305, the baffle 303 will be reset under the reverse force of the pressing spring 306, and can protect the placed sealing ring again to prevent the sealing ring from bouncing off.

[0033] like Figures 6 and 7 As shown, a sliding groove is provided at the sliding engaging position of the sliding plate 301 and the support block 302. The surface of the support block 302 is arc-shaped and is provided with an anti-slip pad with a low friction coefficient. A slider is fixedly connected to the bottom of the matching plate 304, and a tension spring 309 is provided between the slider and the sliding plate 301.

[0034] During operation, when the three groups of spreading blocks 302 are moved outward by the force of the active plate 411 to spread the sealing ring, there will be a certain gap between each group of spreading blocks 302. At this time, in order to prevent the sealing ring from being spread into a triangle during the spreading process, sliding grooves are provided on the surfaces of the spreading blocks 302. This can reduce the contact area of ​​the spreading blocks 302 when spreading the sealing ring, and a certain force can be provided to spread the sealing gasket for easy installation. In addition, the provision of the sliding grooves can keep the sealing ring in a complete state to a certain extent, making it easier to install it in the sealing position of the high-voltage connector. It should be noted that by designing the contact surface between the expansion block 302 and the sealing ring into an arc surface and installing an anti-slip pad with a low friction coefficient, the sealing ring can be prevented from bouncing to a certain extent. On the other hand, the stability of the expansion block 302 after the sealing ring is expanded can be improved, and the sealing ring can be easily detached. It should be noted again that when the sliding plate 301 slides through the notch opened on the side of the connecting sleeve 2, the width of the matching plate 304 does not allow it to slide, so its position is fixed. In order to prevent the inclined end of the push plate 305 from always contacting the angle between the baffle 303 and the fixed plate 307, causing the baffle 303 to be unable to be effectively reset, a slider is provided on the bottom surface of the matching plate 304, and a tension spring 309 is provided between the slider and the sliding plate 301. When the sliding plate 301 slides out of the notch, the matching plate 304 will be fixed in position again under the action of the tension spring 309, which can effectively increase the force applied by the push plate 305 on the side of the matching plate 304 to flip the baffle 303, resulting in high stability and convenient placement and protection of the sealing ring.

[0035] like Figure 7 As shown, one end of the tension spring 309 is fixedly connected to the sliding plate 301, and the other end is fixedly connected to the slider, the angle between the baffle 303 and the fixed plate 307 is 90°, and the push plate 305 is tilted at an angle of 60°.

[0036] During operation, when the sliding plate 301 slides in the notch opened on the side of the connecting sleeve 2, the position of the matching plate 304 is fixed. When the tension spring 309 is stretched to a certain extent, the reset of the tension spring 309 will also drive the sliding plate 301 to reset. On the one hand, it can improve the stability of the reset of the sliding plate 301 and avoid the position deviation of the sealing ring placed on the surface of the sliding plate 301 caused by rapid reset. On the other hand, it can ensure the position of the matching plate 304, so that it can stably apply a flipping thrust to the baffle 303 through the push plate 305, thereby improving the stability of the baffle 303 and avoiding the frequent replacement of the pressing spring 306 due to excessive stretching or compression.

[0037] like Figures 4 to 7 As shown, the baffle 303 is arranged in an L shape and is made of a lightweight aluminum alloy material. The movement of the support block 302 can drive the sliding plate 301 to slide on the surface of the connecting sleeve 2.

[0038] During operation, after the expansion block 302 moves to expand the sealing ring, the extrusion and telescopic plate 405 below will also rise due to the rise of the moving rod 403. When the high-voltage connector is placed in the middle position of multiple sets of expansion blocks 302, the extrusion and telescopic plate 405 can also support the placed high-voltage connector to a certain extent, and can better prevent the expansion block 302 from descending too quickly and causing the sealing ring to fly off. Moreover, the baffle 303 is set in an L shape. After it is flipped over, it can be quickly removed from the upper flip of the sealing ring, making it convenient for the sealing ring to be quickly placed on the top of the sliding plate 301, and the sealing ring can continue to be quickly expanded and installed on the high-voltage connector.

[0039] like Figures 4 to 7 As shown, a friction pad is provided at the inclined end of the push plate 305, the matching plate 304 and the push plate 305 are fixedly connected, the upper end of the pressing spring 306 is fixedly connected to the side of the baffle 303, and the pressing spring 306 is arranged in an arc shape.

[0040] When the locking cam 306 is in the unlock state, the locking cam 306 is in the unlock state, and the locking cam 306 is in the unlock state, so that the locking cam 306 is locked.
