Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a solenoid valve disassembly positioner. Background Technology
[0002] The transmission solenoid valve is a key actuator in the automatic transmission control system. It controls the opening and closing of the hydraulic oil circuit and the pressure regulation through electromagnetic principles, thereby realizing gear shifting and working mode switching. Its core function is to convert the electrical signals of the electronic control unit (ECU) into mechanical actions of the hydraulic system, ensuring that the transmission completes gear changes accurately and smoothly. Its main structure consists of an electromagnetic coil, valve core (movable iron core / armature), valve body, spring, seals, etc.
[0003] In the prior art, the solenoid valve assembly of the gearbox needs to be disassembled after cleaning. The assembly is positioned by a movable clamp and then pulled apart. However, the size of the gearbox solenoid valve is not uniform. Its size is usually designed according to the application scenario, diameter and functional requirements. The existing disassembly clamp cannot be adapted to the size of different assemblies, resulting in poor matching between the clamp and the assembly, which affects the clamping and positioning effect. Customizing additional clamps will increase the disassembly cost. Utility Model Content
[0004] The purpose of this invention is to provide a solenoid valve disassembly and positioning device. By rotating a bidirectional screw, two clamping plates are driven to move synchronously in opposite directions. The distance between the clamping plates is adjusted to adapt to the size of different solenoid valve kits, thereby improving the matching degree between the clamping plates and the kits and the clamping and positioning effect. No additional customized matching fixtures are required, saving disassembly costs.
[0005] The specific technical solution adopted by this utility model is as follows: A solenoid valve disassembly and positioning device includes a support column disposed at one end of a fixed base plate and a sliding base plate. A connecting plate is vertically mirror-image disposed on the top of the support column. A bidirectional screw is rotatably disposed between the two ends of the connecting plate. The outer wall of the bidirectional screw is threaded with opposite directions. A set of clamping plates is mirror-symmetrically disposed between the two connecting plates. Each set includes two mirror-symmetrical clamping plates. The ends of the clamping plates are provided with equally spaced teeth. The teeth of adjacent clamping plates in each set are arranged in an interlocking manner. Sliding rods are symmetrically fixedly connected to the side walls of the clamping plates. The sliding rods pass through the connecting plates and slide with them. A horizontal plate is fixedly connected between the two sliding rods. The horizontal plate is threadedly connected to the bidirectional screw.
[0006] The connecting plate is symmetrically fixedly connected to the middle of the connecting plate, and the middle of the bidirectional screw is rotatably connected to the supporting plate.
[0007] The bottom of the fixed base plate is fixedly connected to a guide rail, and a sliding base plate is provided on one side of the fixed base plate. The sliding base plate is driven by a servo electric cylinder to reciprocate along the guide rail.
[0008] The output end of the servo electric cylinder is rigidly connected to the sliding base plate, and a limiting plate is sleeved on the end of the sliding base plate.
[0009] Servo cylinders are fixedly assembled on the top of both the fixed base plate and the sliding base plate. A lever plate is rotatably connected to the output end of the servo cylinder. A support plate is rotatably installed on the top of the servo cylinder. The support plate and the lever plate form a rotating pair in the middle.
[0010] An electric control switch is fixed on one side of the fixed base plate to control the start and stop of the servo electric cylinder and the servo air cylinder.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0016] like Figures 1-3 As shown, a solenoid valve disassembly and positioning device includes a support column 2 disposed at one end of a fixed base plate 1 and a sliding base plate 102. A connecting plate 201 is vertically mirror-image disposed on the top of the support column 2. A bidirectional screw 203 is rotatably disposed between the two ends of the connecting plate 201. The outer wall of the bidirectional screw 203 has threads with opposite directions of rotation. A bearing plate 202 is symmetrically fixedly connected to the middle of the connecting plate 201. The middle of the bidirectional screw 203 is rotatably connected to the bearing plate 202. A set of clamping plates 204 is mirror-symmetrically disposed between the two connecting plates 201. Each group includes two mirror-symmetrical clamping plates 204. The ends of the clamping plates 204 are provided with equally spaced toothed plates 205. The toothed plates 205 of adjacent clamping plates 204 in each group are arranged in an interlocking manner. The side walls of the clamping plates 204 are symmetrically fixedly connected with sliding rods 206. The sliding rods 206 pass through the connecting plate 201 and slide with it. A horizontal plate 207 is fixedly connected between the two sliding rods 206. The horizontal plate 207 is threadedly connected to the bidirectional screw 203. The two connecting plates 201 are fixedly connected to the support column 2 and the lever plate 107 respectively.
[0017] Based on the above structure, before pulling and disassembling the solenoid valve assembly, the distance between the two clamping plates 204 in each group needs to be adjusted. One end of the lever 107 and the support column 2 is connected to a connecting plate 201. Rotating the bidirectional screws 203 on the two connecting plates 201 causes the horizontal plate 207 and sliding rod 206 to slide in opposite directions along the connecting plate 201, distancing the two clamping plates 204. The assembly is then placed between the two clamping plates 204 at one end of the support column 2, ensuring that the center of the assembly is below the top sectional surface of the clamping plate 204. Then, the lever 107 is rotated via the electronic switch 105, causing the clamping plate 204 at one end of the lever 107 to rotate and descend, clamping the assembly between the upper and lower sets of clamping plates 204. At this point, the distance is adjusted again by rotating the two bidirectional screws 203. The spacing between the two clamping plates 204 in each group causes the kit to be squeezed upwards. During adjustment, ensure that the ends of the upper and lower clamping plates 204 are aligned and close together. When the bidirectional screw 203 cannot rotate, the upper and lower clamping plates 204 have clamped the kit. Since the ends of the upper and lower clamping plates 204 are aligned and close together, the center of the kit will be on the same horizontal plane as the end face of the clamping plate 204, ensuring matching and firm clamping of subsequent kits. When the toothed plates 205 at the ends of the clamping plates 204 in each group are interlocked, the two clamping plates 204 can be brought closer together, which is suitable for small-sized kits. The support plate 202 is attached to the bottom of the toothed plate 205, which can help support the clamping plates 204. After the test and matching are completed, the clamping plates 204 at the ends of the lever plate 107 can be rotated and moved upwards to reset by the electric control switch 105.
[0018] See attached document Figures 1-3A guide rail 101 is fixedly connected to the bottom of the fixed base plate 1. A sliding base plate 102 is provided on one side of the fixed base plate 1. The sliding base plate 102 is driven by a servo cylinder 104 to reciprocate along the guide rail 101. The output end of the servo cylinder 104 is rigidly connected to the sliding base plate 102. A limiting plate 103 is sleeved on the end of the sliding base plate 102. A servo cylinder 106 is fixedly assembled on the top of both the fixed base plate 1 and the sliding base plate 102. A lever plate 107 is rotatably connected to the output end of the servo cylinder 106. A support plate 108 is rotatably installed on the top of the servo cylinder 106. The support plate 108 and the lever plate 107 form a rotating pair in the middle. An electric control switch 105 is fixedly provided on one side of the fixed base plate 1 to control the start and stop of the servo cylinder 104 and the servo cylinder 106.
[0019] Based on the above structure, when formally disassembling the solenoid valve assembly, since the assembly is composed of two sleeves joined together, the assembly needs to be placed inside the clamping plates 204 on top of the two support columns 2. That is, both ends of the assembly are located in the two clamping plates 204 respectively. The servo cylinder 106 is triggered by the electric control switch 105, and the servo cylinder 106 extends, driving the lever plate 107 to rotate and move downward. The clamping plate 204 at the end of the lever plate 107 and the clamping plate 204 at the end of the support column 2 come into close contact to clamp the assembly. At the same time, the electric control switch 105 obtains the time delay from its internal time delay device, such as a time relay or PLC. Taking the time relay as an example, it obtains the time delay from the electric control switch 105. After the trigger signal is received, a timer starts (2-3 seconds), which is the process of the lever plate 107 rotating and moving down to clamp the kit. After the timer ends, a signal is output to the servo cylinder 104 to trigger the action. The output end of the servo cylinder 104 retracts, causing the sliding base plate 102 to slide along the guide rail 101. The support column 2, servo cylinder 106, clamping plate 204 and other components on the guide rail 101 will all move together. By moving, half of the kit that has been clamped is pulled out, while the other half of the kit remains on the clamping plate 204 of the support column 2 at one end of the fixed base plate 1. The limiting plate 103 is fixed as a safety device and is used to limit the sliding stroke of the sliding base plate 102. This invention drives two clamping plates 204 to move synchronously in opposite directions by rotating a bidirectional screw 203, adjusting the distance between the clamping plates 204 to adapt to the size of different solenoid valve kits, improving the matching degree between the clamping plates 204 and the kits and the clamping and positioning effect, eliminating the need for additional customized fitting fixtures and saving disassembly costs.
[0020] The working principle of this utility model is as follows: According to the above structure, before pulling and disassembling the solenoid valve assembly, it is necessary to adjust the distance between the two clamping plates 204 in each group. One end of the lever plate 107 and the support column 2 are connected to the connecting plate 201. Rotate the bidirectional screw 203 on the two connecting plates 201 respectively. The bidirectional screw 203 rotates and drives the horizontal plate 207 and the sliding rod 206 to slide in opposite directions along the connecting plate 201, and the two clamping plates 204 move away from each other. Furthermore, place the kit between the two clamping plates 204 at one end of the support column 2, and confirm that the center of the kit is lower than the top cross-section of the clamping plate 204. Then, control the lever 107 to rotate through the electric control switch 105, so that the clamping plate 204 at one end of the lever 107 rotates and descends, and the kit is clamped between the upper and lower clamping plates 204. At this time, by rotating the two bidirectional screws 203 respectively, the distance between the two clamping plates 204 in each group is adjusted again, and the kit is squeezed and moved upward. Note that during the adjustment process, the ends of the upper and lower clamping plates 204 should be aligned and close together. Furthermore, when the bidirectional screw 203 cannot rotate, the upper and lower clamping plates 204 have clamped the kit. Since the ends of the upper and lower clamping plates 204 are aligned and close together, the center of the kit will be on the same horizontal plane as the end tangent of the clamping plate 204, ensuring the matching and firmness of the subsequent kit clamping. When the toothed plates 205 at the ends of the clamping plates 204 in each set are engaged with each other, the two clamping plates 204 can be brought closer together, which is suitable for small-sized kits. The support plate 202 is attached to the bottom of the toothed plate 205, which can help support the clamping plate 204. After the test matching is completed, the clamping plate 204 at the end of the lever plate 107 can be rotated and moved upward to reset by the electric control switch 105. Furthermore, when formally disassembling the solenoid valve kit, since the kit is composed of two sleeves spliced together, the kit needs to be placed inside the clamping plates 204 on the top of the two support columns 2. That is, both ends of the kit are located in the two clamping plates 204 respectively. The servo cylinder 106 is triggered by the electric control switch 105. The servo cylinder 106 extends and drives the lever plate 107 to rotate and move downward. The clamping plate 204 at the end of the lever plate 107 and the clamping plate 204 at the end of the support column 2 come into close contact to clamp the kit. At the same time, the electric control switch 105 uses its internal time delay device, such as a time relay or PLC. Taking the time relay as an example, after receiving the trigger signal from the electric control switch 105, it starts timing (2-3 seconds), which is the process of the lever plate 107 rotating and moving downward to clamp the kit. Furthermore, after the timing ends, an output signal is sent to the servo cylinder 104 to trigger an action. The output end of the servo cylinder 104 retracts, causing the sliding base plate 102 to slide along the guide rail 101. The support column 2, servo cylinder 106, clamping plate 204 and other components on the guide rail 101 will all move together. By moving, half of the clamped kit is pulled out, while the other half of the kit remains on the clamping plate 204 of the support column 2 at one end of the fixed base plate 1. The limiting plate 103 is fixed as a safety device and is used to limit the sliding stroke of the sliding base plate 102.
