Description
Technical Field
[0001] This invention relates to the field of testing equipment technology, and in particular to a rapid testing and repair tool for a gearbox valve body pressure valve. Background Technology
[0002] The transmission valve body is the core hydraulic control unit of automatic transmissions, dual-clutch transmissions, and some CVT transmissions.
[0003] The solenoid valve on the transmission valve body is the core switching element between the electronic control unit (TCU) and the hydraulic system. Its core function is to receive electrical signal commands from the TCU and precisely control the on / off state, flow direction, and flow rate of hydraulic oil by changing the position of its own valve core. This drives actuators such as clutches and brakes to complete gear shifting. The transmission control unit (TCU) outputs an electrical signal with an adjustable duty cycle (i.e., the on-time ratio of the pulse signal) to change the average current of the solenoid valve coil. The current determines the strength of the electromagnetic attraction, which in turn controls the axial movement of the valve core (adjustable opening). The larger the current, the larger the valve core opening, and the higher the hydraulic oil flow / pressure; the smaller the current, the smaller the valve core opening, and the lower the oil pressure.
[0004] The transmission valve body is equipped with multiple solenoid valves. When the transmission valve body malfunctions, the solenoid valves need to be removed and inspected to locate the damaged solenoid valve and then repair it. Current technology usually uses a testing workbench to inspect the solenoid valves, but this method has certain drawbacks. For example, after inserting the solenoid valve to be inspected into the testing seat on the testing workbench, the solenoid valve is usually limited and fixed by bolts and lock nuts, which is inconvenient to use.

[0016] The beneficial effects of this invention are: 1. In the initial state of use, the vertical positioning component limits and fixes the rotating arm, which is perpendicular to the testing worktable. This facilitates the operator inserting one end of the solenoid valve to be tested into the mounting hole. The operator then rotates the rotating arm downwards, causing the moving plate, contact plate, connecting block one, and connector to move together until the rotating arm is parallel to the testing worktable. At this point, the horizontal positioning component supports and positions the rotating arm. The moving plate, contact plate, connecting block one, and connector are located near the end of the solenoid valve. Then, under the action of the control component... The control unit moves the movable plate, contact plate, connecting block 1, and plug towards the solenoid valve until the contact plate touches the end of the solenoid valve. During this process, the plug moves and inserts into the slot of the solenoid valve to cooperate in the testing of the solenoid valve. After the test is completed, the control unit moves the movable plate, contact plate, connecting block 1, and plug away from the solenoid valve. Then, the operator flips the rotating arm upward and limits and fixes the rotating arm again through the set vertical positioning component. Then, the operator can remove the tested solenoid valve from the mounting hole. The operation is convenient.
[0017] 2. In the initial state, the electromagnet is de-energized, and the sliding block and the iron block are far away from the electromagnet to avoid affecting the downward rotation of the rotating arm. When the rotating arm rotates to a horizontal position, the moving plate and the contact plate are near the end of the solenoid valve. When the electromagnet is energized, it magnetically attracts the iron block, thereby moving the sliding block, the moving plate, and the contact plate closer to the solenoid valve. During this process, the spring is stretched and deformed, storing elastic potential energy. After the solenoid valve is detected, the electromagnet is de-energized, and the elastic potential energy stored in the spring is released, causing the sliding block, the moving plate, the contact plate, and the connector to move away from the solenoid valve.
[0018] 3. In the initial state, the left baffle blocks the upper end of the fluid guide cover, while the right baffle is positioned away from the left baffle. This provides a disassembly and maintenance area for the disassembly of the transmission valve body and the solenoid valve, preventing disassembled parts from rolling off. After the solenoid valve is disassembled and the transmission valve body is assembled, the operator can push the right baffle closer to the left baffle. The right baffle moves the right U-shaped seat and the contact block together, thereby applying pressure to the left U-shaped seat through the contact block, causing the left baffle to move away from the upper end of the fluid guide cover, thus releasing the blockage. This allows the right baffle to scrape the oil dripping onto the upper surface of the testing workbench during transmission valve body disassembly into the fluid guide cover, and then guide it into the oil tank. After the waste oil is scraped and cleaned, the right baffle can be moved to the right to reset. During this process, the left baffle, under the action of the elastic reset component, moves and resets to above the fluid guide cover, re-blocking the upper end of the fluid guide cover.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0022] Reference Figures 1-12 A rapid testing and repair tool for a gearbox valve body pressure valve includes a testing workbench 100. A testing seat 101 is fixed to the upper surface of the testing workbench 100. A mounting hole 102 is provided on one side of the testing seat 101. A flow channel for use with the mounting hole 102 is provided on the testing seat 101. The testing seat 101 is prior art. Rotating arms 103 are rotatably provided on both sides of the testing seat 101. A movable plate 104 is movably arranged between the two rotating arms 103. An abutment is fixed on one side of the movable plate 104. Two connecting blocks 106 are symmetrically fixed on one side of the movable plate 104, and a connector 107 is fixed between the two connecting blocks 106. The connector 107 is electrically connected to the detection worktable 100 by a connecting wire 108. A control component for use with the movable plate 104 is provided on the rotating arm 103. A vertical positioning component and a horizontal positioning component for use with the rotating arm 103 are provided on the detection seat 101. A liquid supply component for use with the detection seat 101 is provided on the detection worktable 100.
[0023] The present application is used to test the solenoid valve 900 that has been removed from the gearbox valve body. The solenoid valve 900 has a slot 901 and is a prior art device.
[0024] The testing workbench 100 is existing technology, and using the testing workbench 100 to test the solenoid valve 900 is a conventional technical means in this field.
[0025] In use, the vertical positioning component initially limits and fixes the rotating arm 103, making it perpendicular to the testing workbench 100. This facilitates the operator inserting one end of the solenoid valve 900 to be tested into the mounting hole 102. The operator then rotates the rotating arm 103 downwards, causing the moving plate 104, contact plate 105, connecting block 106, and connector 107 to move together until the rotating arm 103 is parallel to the testing workbench 100. At this point, the horizontal positioning component supports and positions the rotating arm 103. The moving plate 104, contact plate 105, connecting block 106, and connector 107 are located near the end of the solenoid valve 900. Then, under the action of the control component, the rotating arm 103 is moved... The movable plate 104, the contact plate 105, the connecting block 106, and the plug 107 move toward the solenoid valve 900 until the contact plate 105 contacts the end of the solenoid valve 900. During this process, the plug 107 moves and inserts into the slot 901 of the solenoid valve 900, thus cooperating to perform the testing of the solenoid valve 900. After the test is completed, the control component causes the movable plate 104, the contact plate 105, the connecting block 106, and the plug 107 to move away from the solenoid valve 900. Then, the operator flips the rotating arm 103 upward, and the vertical positioning component limits and fixes the rotating arm 103 again. Then, the operator can remove the tested solenoid valve 900 from the mounting hole 102. The operation is convenient.
[0026] Each of the two rotating arms 103 has a sliding groove 200 on its opposite surface. A sliding block 201 is slidably disposed in each sliding groove 200. A moving plate 104 is fixed between the two sliding blocks 201. Multiple guide rods are fixed on one side of each sliding block 201. One end of each guide rod 1 movably passes through the rotating arm 103 and is fixed with a connecting plate 203. A spring 204 is fixed between the connecting plate 203 and the rotating arm 103. The spring 204 is movably sleeved on the outer surface of the guide rod 1.
[0027] In the initial state, the spring 204 causes the sliding block 201, the moving plate 104, and the abutment plate 105 to be in a position away from the higher position. When the moving plate 104 and the abutment plate 105 are flipped downwards with the rotating arm 103, they collide with the solenoid valve 900.
[0028] The control assembly includes two electromagnets 300, each of which is fixed in a corresponding sliding groove 200. Each sliding block 201 has an iron block 301 fixed on the side near the electromagnet 300. The detection workbench 100 is equipped with a controller that works with the electromagnets 300. The controller is existing technology and is used to control the power supply of the electromagnets 300.
[0029] In the initial state, the electromagnet 300 is de-energized, and the sliding block 201 and the iron block 301 are far away from the electromagnet 300 to avoid affecting the downward flipping of the rotating arm 103. When the rotating arm 103 rotates to a horizontal state, the moving plate 104 and the contact plate 105 are located near the end of the solenoid valve 900. When the electromagnet 300 is energized, it magnetically attracts the iron block 301, thereby driving the sliding block 201, the moving plate 104, and the contact plate 105 to move closer to the solenoid valve 900. During this process, the spring 204 is stretched and deformed, storing elastic potential energy. After the solenoid valve 900 is detected, the electromagnet 300 is de-energized, and the elastic potential energy stored in the spring 204 is released, causing the sliding block 201, the moving plate 104, the contact plate 105, and the connector 107 to move away from the solenoid valve 900.
[0030] The vertical positioning assembly includes a connecting seat 400 fixed to the upper surface of the detection seat 101. The connecting seat 400 has mounting grooves on both sides. Each mounting groove has a movable abutment ball 401. A spring is fixed between the abutment ball 401 and the inner wall of the mounting groove. The inner wall of the rotating arm 103 has an abutment groove 402 that cooperates with the abutment ball 401.
[0031] In the initial state, the rotating arm 103 is in a vertical position. At this time, the abutting ball 401 abuts against the abutting groove 402, and the spring is in a compressed state, thereby cooperating with the abutting ball 401 to limit and fix the rotating arm 103.
[0032] The lateral positioning assembly includes connecting seats 2 500 fixed on both sides of the detection seat 101. Each connecting seat 2 500 has a cavity 1 501. A contact switch 502 is fixed at the bottom of each cavity 1 501. The contact switch 502 is used in conjunction with the controller mentioned above. A lifting rod 503 is movably arranged in the cavity 1 501. The upper end of the lifting rod 503 movably passes through the connecting seat 2 500. A connecting plate 2 504 is fixed at the lower end of the lifting rod 503. A spring 3 505 is fixed between the connecting plate 2 504 and the top of the cavity 1 501. The spring 3 505 is movably sleeved on the outer surface of the lifting rod 503.
[0033] In the initial state, the connecting plate 504 is located away from the contact switch 502. When the rotating arm 103 rotates from the vertical state to the horizontal state, the rotating arm 103 will abut against the upper end of the lifting rod 503, thereby causing the lifting rod 503 to move downward. During the downward movement of the lifting rod 503, the connecting plate 504 will move downward and approach the contact switch 502. When the rotating arm 103 rotates to the horizontal state, the connecting plate 504 touches the upper end of the contact switch 502, thereby sending an electrical signal to cooperate with the controller to energize the electromagnet 300.
[0034] The testing workbench 100 has a cavity 600, and an oil tank 601 is fixed inside the cavity 600. A liquid pump is fixed at the bottom of the oil tank 601. A filter is connected to the inlet end of the liquid pump, and a supply pipe 602 is connected to the outlet end of the liquid pump. One end of the supply pipe 602 is connected to the testing seat 101. A drain pipe 603 is connected to one side of the testing seat 101, and one end of the drain pipe 603 extends into the oil tank 601.
[0035] This section describes existing technology, and the principle of testing the solenoid valve 900 is a conventional technique in this field.
[0036] The upper surface of the testing workbench 100 is symmetrically fixed with two side plates 700. A left U-shaped seat 701 is slidably mounted on each of the two side plates 700. A left baffle 702 is fixed between the two left U-shaped seats 701. A liquid guide cover 703 is provided between the upper surface of the testing workbench 100 and the oil tank 601. A right U-shaped seat 704 is slidably mounted on each of the two side plates 700. A right baffle 705 is fixed between the two right U-shaped seats 704. An abutment block 706 is fixed on one side of the right U-shaped seat 704. An elastic reset component is provided on the side plate 700 to cooperate with the left baffle 702. A limiting component is provided on the side plate 700 to cooperate with the right baffle 705.
[0037] Depending on actual needs, a piston layer can be fixed on the side wall of the right baffle 705, so that the oil can be scraped off more cleanly.
[0038] In the initial state, the left baffle 702 blocks the upper end of the fluid guide cover 703, and the right baffle 705 is positioned away from the left baffle 702. This provides a disassembly and maintenance area for the disassembly of the gearbox valve body and the solenoid valve 900, preventing disassembled parts from rolling off. After the solenoid valve 900 is disassembled and the gearbox valve body is installed and assembled, the operator can push the right baffle 705 closer to the left baffle 702. The right baffle 705 moves the right U-shaped seat 704 and the contact block 706 together, thereby applying pressure to the left U-shaped seat 701 through the contact block 706. By applying force, the left baffle 702 is moved away from the upper end of the fluid guide cover 703, thereby releasing the blockage of the fluid guide cover 703. This allows the right baffle 705 to scrape the oil that dripped onto the upper surface of the testing workbench 100 during the disassembly of the gearbox valve body into the fluid guide cover 703, and then guide it through the fluid guide cover 703 to drip into the oil tank 601. After the waste oil is scraped and cleaned, the right baffle 705 can be moved to the right to reset. During this process, the left baffle 702, under the action of the elastic reset component, moves and resets to above the fluid guide cover 703, sealing the upper end of the fluid guide cover 703 again.
[0039] The disassembly of the gearbox valve body and the disassembly and repair of the solenoid valve 900 are existing technologies. The disassembly and repair of the solenoid valve 900 usually involves replacing the damaged parts.
[0040] Each side plate 700 has a limiting groove 800 on its side wall. The left limiting slider 801, which is used in conjunction with the limiting groove 800, is fixed on the inner wall of the left U-shaped seat 701. The right limiting slider, which is used in conjunction with the limiting groove 800, is fixed on the inner wall of the right U-shaped seat 704.
[0041] The movement of the left U-shaped seat 701 is limited and guided by the cooperation of the left limit slider 801 and the limit groove 800.
[0042] The movement of the right U-shaped seat 704 is limited and guided by the cooperation of the right limit slider and the limit groove 800.
[0043] The elastic reset assembly includes multiple guide rods 802 fixed to one side of the left limiting slider 801. One end of the guide rod 802 movably passes through the side plate 700. A spring 803 is fixed between the limiting slide groove 800 and the left limiting slider 801.
[0044] In the initial state, the left baffle 702 blocks the upper end of the liquid guide cover 703. When the right U-shaped seat 704 pushes the left U-shaped seat 701 to move with the abutment block 706, the left U-shaped seat 701 drives the left limit slider 801 and the guide rod 802 to move together, causing the left baffle 702 to move away from the liquid guide cover 703. During this process, the spring 803 is squeezed and contracted, preparing for the subsequent reset of the left baffle 702.
[0045] The limiting component includes an arc-shaped locking block 804 fixed to the upper surface of the side plate 700, and an arc-shaped slot for use with the arc-shaped locking block 804 is provided on the inner top of the right U-shaped seat 704.
[0046] When the right baffle 705 moves to the left and is close to the liquid guide cover 703, the right baffle 705 drives the right U-shaped seat 704 to move together until the right U-shaped seat 704 engages with the arc-shaped engaging block 804, thereby limiting and fixing the right U-shaped seat 704 and the right baffle 705.
[0047] In use, the invention initially limits and fixes the rotating arm 103, making it perpendicular to the testing workbench 100. This facilitates the operator inserting one end of the solenoid valve 900 to be tested into the mounting hole 102. The operator then rotates the rotating arm 103 downwards, causing the moving plate 104, contact plate 105, connecting block 106, and connector 107 to move together until the rotating arm 103 is parallel to the testing workbench 100. At this point, the horizontal positioning component supports and positions the rotating arm 103. The moving plate 104, contact plate 105, connecting block 106, and connector 107 are located near the end of the solenoid valve 900. Then, under the action of the control component, the moving plate 104, contact plate 105, connecting block 106, and connector 107 are moved downwards. The moving plate 104, the contact plate 105, the connecting block 106, and the plug 107 move toward the solenoid valve 900 until the contact plate 105 contacts the end of the solenoid valve 900. During this process, the plug 107 moves and inserts into the slot 901 of the solenoid valve 900 to cooperate in the testing of the solenoid valve 900. After the test is completed, the control component causes the moving plate 104, the contact plate 105, the connecting block 106, and the plug 107 to move away from the solenoid valve 900. Then, the operator flips the rotating arm 103 upward and limits and fixes the rotating arm 103 again through the set vertical positioning component. Then, the operator can remove the tested solenoid valve 900 from the mounting hole 102. The operation is convenient. In the initial state, the electromagnet 300 is de-energized, and the sliding block 201 and the iron block 301 are far away from the electromagnet 300 to avoid affecting the downward flipping of the rotating arm 103. When the rotating arm 103 rotates to a horizontal state, the moving plate 104 and the contact plate 105 are located near the end of the solenoid valve 900. When the electromagnet 300 is energized, it magnetically attracts the iron block 301, thereby driving the sliding block 201, the moving plate 104, and the contact plate 105 to move closer to the solenoid valve 900. During this process, the spring 204 is stretched and deformed, storing elastic potential energy. After the solenoid valve 900 is detected, the electromagnet 300 is de-energized. At this time, the elastic potential energy stored in the spring 204 is released, causing the sliding block 201, the moving plate 104, the contact plate 105, and the connector 107 to move away from the solenoid valve 900. In the initial state, the left baffle 702 blocks the upper end of the fluid guide cover 703, and the right baffle 705 is positioned away from the left baffle 702. This provides a disassembly and maintenance area for the disassembly of the gearbox valve body and the solenoid valve 900, preventing disassembled parts from rolling off. After the solenoid valve 900 is disassembled and the gearbox valve body is installed and assembled, the operator can push the right baffle 705 closer to the left baffle 702. The right baffle 705 moves the right U-shaped seat 704 and the contact block 706 together, thereby applying pressure to the left U-shaped seat 701 through the contact block 706. By applying force, the left baffle 702 is moved away from the upper end of the fluid guide cover 703, thereby releasing the blockage of the fluid guide cover 703. This allows the right baffle 705 to scrape the oil that dripped onto the upper surface of the testing workbench 100 during the disassembly of the gearbox valve body into the fluid guide cover 703, and then guide it through the fluid guide cover 703 to drip into the oil tank 601. After the waste oil is scraped and cleaned, the right baffle 705 can be moved to the right to reset. During this process, the left baffle 702, under the action of the elastic reset component, moves and resets to above the fluid guide cover 703, sealing the upper end of the fluid guide cover 703 again.
