Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a solenoid valve core disassembly device. 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. The main structure consists of an electromagnetic coil, valve core (movable iron core / armature), valve body, spring, seals, etc. The oil circuit layered valve sleeve in the valve core, as a sleeve structure, cooperates with the outer wall of the valve core to provide full-stroke guidance.

[0003] In the prior art, the layered valve sleeve of the solenoid valve core is usually made of multiple layers of metal sleeves axially connected, including an outer carbon steel sleeve and a copper alloy sleeve connected to both ends of the middle brass sleeve. They are tightly connected and small in size, requiring the use of tools such as pullers and wrenches for disassembly, which is often quite laborious. Moreover, being clamped at one point in the sleeve, it is easy to experience uneven force, which can lead to deformation of the valve sleeve and affect the valve core performance. Utility Model Content

[0004] The purpose of this invention is to provide a solenoid valve core disassembly device. The main cylinder controls lever plate one and lever plate two to rotate in a lever-like manner. A pair of stripping rods on lever plate one applies pressure to knock off the sleeve workpiece, causing the sleeve to separate initially. Lever plate two can clamp the sleeve workpiece in the groove. The movement of the stripping plate performs secondary stripping of the sleeve workpiece, thereby disassembling the multi-layer valve sleeve of the valve core. This method is quick and labor-saving, avoids uneven force caused by single-point clamping, prevents workpiece deformation and scrapping, and ensures the valve core's performance.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A solenoid valve core disassembly device includes a support plate. A discharge mechanism and a pull-out mechanism are respectively provided on both sides of the top of the support plate. A pneumatic lever mechanism is assembled in the middle of the support plate for linkage control of the bidirectional action of the discharge mechanism's elastic release and the pull-out mechanism's clamping and positioning. The pneumatic lever mechanism includes a main cylinder. A lever plate 1 and a lever plate 2 are symmetrically rotatably connected to the output end of the main cylinder. A support plate is symmetrically rotatably connected to the top of the main cylinder. One end of the support plate is rotatably connected to both lever plate 1 and lever plate 2. An arc-shaped pressure plate is symmetrically fixedly connected to one end of lever plate 1.

[0007] The pneumatic lever mechanism is provided with a unloading mechanism on the left side for positioning and bearing the workpiece and disassembling it in steps. The unloading mechanism includes an unloading frame, which is fixedly connected to the top of the support plate. A U-shaped groove is provided on one side of the top of the unloading frame. A stripping rod is elastically slidably provided above the U-shaped groove. A protruding rod is symmetrically fixedly connected to the outer wall of the end of the stripping rod.

[0008] The right side of the pneumatic lever mechanism is provided with a material pulling mechanism for positioning, clamping, and disassembling the workpiece. The material pulling mechanism includes a material pulling frame, which is fixedly connected to the top of the support plate. An auxiliary cylinder is fixedly assembled on the top of the support plate, and a material pulling plate is fixedly connected to the output end of the auxiliary cylinder. The top of the material pulling plate, the material pulling frame, and the bottom of the lever plate are all provided with grooves.

[0009] The unloading rack is configured as n-shaped, and the top of the U-shaped groove is provided with an expanded edge groove. The side walls of the unloading rod are symmetrically fixed with connecting plates, and each connecting plate is slidably connected to the unloading rack through a limiting rod at one end.

[0010] The outer wall of the limiting rod is fitted with a spring column, and the connecting plate is elastically connected to the unloading frame through the spring column.

[0011] The unloading rack is slidably connected to a sliding plate on the side wall adjacent to the U-shaped groove. One end of the sliding plate is fixedly connected to the unloading rod. A magnetic suction plate is fixedly assembled on the side wall of the sliding plate facing the U-shaped groove.

[0012] A through hole is provided in the middle of the U-shaped groove. Sliding grooves are provided on the inner wall of the U-shaped groove on both sides of the through hole. An anti-magnetic plate is slidably provided inside the through hole. The anti-magnetic plate is slidably connected to the sliding groove. A magnetic block is fixedly assembled on the side wall of the anti-magnetic plate. The magnetic block and the magnetic plate are opposite each other with the same pole.

[0013] The material pulling plate is located between the auxiliary cylinder and the material pulling frame. A control switch is fixedly assembled on one side of the support plate, and the control switch integrates a delayed start device for sequentially controlling the start of the main cylinder and the auxiliary cylinder. The control switch is electrically connected to the main cylinder and the auxiliary cylinder.

[0014] The support plate has a sloping surface at one end below the unloading rack, and a receiving box is fixedly installed at one end of the support plate and on one side of the sloping surface.

[0015] The technical advantages achieved by this utility model are as follows: the main cylinder controls the lever plate one and lever plate two to rotate in a lever-like manner.

[0025] 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.

[0026] like Figures 1-2 As shown, a solenoid valve core disassembly device includes a support plate 1. A discharge mechanism 3 and a pulling mechanism 4 are respectively provided on both sides of the top of the support plate 1. A pneumatic lever mechanism 2 is assembled in the middle of the support plate 1 for linkage control of the bidirectional action of the discharge mechanism 3 elastically releasing material and the pulling mechanism 4 clamping and positioning. The pneumatic lever mechanism 2 includes a main cylinder 21. A lever plate 1 201 and a lever plate 202 are symmetrically rotatably connected to the output end of the main cylinder 21. A support plate 203 is symmetrically rotatably connected to the top of the main cylinder 21. One end of the support plate 203 is rotatably connected to the lever plate 1 201 and the lever plate 202 respectively. An arc-shaped pressure plate 204 is symmetrically fixedly connected to one end of the lever plate 1 201. A control switch 101 is fixedly assembled on one side of the support plate 1, and the control switch 101 integrates a delayed start device for sequentially controlling the start of the main cylinder 21 and the auxiliary cylinder 41. The control switch 101 is electrically connected to the main cylinder 21 and the auxiliary cylinder 41.

[0027] According to the above structure, the main cylinder 21 is triggered by the control switch 101. The solenoid valve of the main cylinder 21 is energized, the cylinder extends, and at the same time, the time delay device, such as a time relay or PLC, is activated. Taking the time relay as an example, after receiving the trigger signal from the control switch 101, it starts timing (2-3 seconds). After the timing is completed, it outputs a signal to the auxiliary cylinder 41 to trigger the action. Since the support plate 203 is rotatably connected to the middle of the lever plate 1 201 and lever plate 202 to form a lever, when the output end of the main cylinder 21 rises, it drives one end of lever plate 1 201 and lever plate 202 to rise, and the other end will fall, that is, the arc-shaped pressure plate 204 at one end of lever plate 1 201 falls.

[0028] See attached document Figures 1-3 , Figures 6-7A unloading mechanism 3 is provided on the left side of the pneumatic lever mechanism 2 for positioning, bearing, and step-by-step disassembly of the workpiece. The unloading mechanism 3 includes an unloading frame 31, which is n-shaped. The top of the U-shaped groove 301 has an enlarged edge groove 302. The unloading frame 31 is fixedly connected to the top of the support plate 1. A U-shaped groove 301 is provided on one side of the top of the unloading frame 31. A stripping rod 306 is elastically slidably provided above the U-shaped groove 301. A connecting plate 305 is symmetrically fixedly connected to the side wall of the stripping rod 306. Each connecting plate 305 is slidably connected to the unloading frame 31 through a limiting rod 303 at one end. A spring column 304 is sleeved on the outer wall of the limiting rod 303. The connecting plate 305 is elastically connected to the unloading frame 31 through the spring column 304. A protruding rod 307 is symmetrically fixedly connected to the outer wall of the end of the stripping rod 306. A sliding plate 308 is slidably connected to the side wall of the unloading rack 31 adjacent to the U-shaped channel 301. One end of the sliding plate 308 is fixedly connected to the unloading rod 306. A magnetic suction plate 309 is fixedly assembled on the side wall of the sliding plate 308 facing the U-shaped channel 301. A through hole 310 is opened through the middle of the U-shaped channel 301. A sliding groove 313 is opened on the inner wall of the U-shaped channel 301 on both sides of the through hole 310. An anti-magnetic plate 312 is slidably installed inside the through hole 310. The anti-magnetic plate 312 is slidably connected to the sliding groove 313. A magnetic block 311 is fixedly assembled on the side wall of the anti-magnetic plate 312. The magnetic block 311 and the magnetic suction plate 309 are opposite each other with the same pole. A slope 103 is opened at one end of the support plate 1 located below the unloading rack 31. A receiving box 102 is fixedly installed at one end of the support plate 1 located on one side of the slope 103.

[0029] According to the above structure, the layered valve sleeve in the valve core is slid into the U-shaped groove 301 from the side. The valve sleeve presses the magnetic block 311, causing it to slide along the sliding groove 313 into the through hole 310. At this time, the outer skirt of the outer sleeve of the valve sleeve is also placed flat in the expansion groove 302. The hand continues to press the side of the valve sleeve without moving. When the arc-shaped pressure plate 204 descends, it presses the protruding rod 307 downward, causing the ejector rod 306 to descend. The arc shape of the arc-shaped pressure plate 204 can decompose the lateral force generated by the rotation of the lever into an effective force in the vertical direction, making the pressure distribution more uniform. When the ejector rod 306 descends, the spring column 304 retracts, and the limiting rod 303 moves down accordingly, limiting the angle of the ejector rod 306 to prevent it from sliding left and right when descending. The sliding plate 308 and the magnetic plate 309 also descend accordingly. The like poles of the magnetic plate 309 and the magnetic block 311 are opposite each other and repel each other. When the magnetic plate 309 descends, its magnetic field passes through the through hole 310. The magnetic block 311 and the non-magnetic plate 312 are pushed towards the receiving box 102. However, due to the pressure of the hand on the valve sleeve, the magnetic poles repel each other and cannot push the outer sleeve. The ejector rod 306 descends and inserts into the inner sleeve of the valve sleeve. The hand is released, and the valve sleeve is no longer pressed. The ejector rod 306 presses down the middle brass sleeve fitted on the inner wall of the outer sleeve, causing it to detach and fall onto the slope 103. It then slides down the slope 103 into the receiving box 102 for further processing. Pressing the control switch 101 retracts the output end of the main cylinder 21, raises the arc-shaped pressure plate 204, and raises the stripping rod 306 under the elastic force of the spring column 304. At this time, the outer sleeve is still located in the U-shaped groove 301. When the sliding plate 308 rises with the stripping rod 306, the magnetic field of the sliding plate 308 passes through the perforation 310 and repels the magnetic block 311. The magnetic block 311 starts to move through the non-magnetic plate 312, and can automatically push the outer sleeve of the valve sleeve outward.

[0030] See attached document Figures 1-4 , Figure 5 The right side of the pneumatic lever mechanism 2 is provided with a material pulling mechanism 4, which is used for positioning, clamping and disassembling the workpiece. The material pulling mechanism 4 includes a material pulling frame 402, which is fixedly connected to the top of the support plate 1. The top of the support plate 1 is fixedly assembled with a secondary cylinder 41. The output end of the secondary cylinder 41 is fixedly connected with a material pulling plate 401. The material pulling plate 401 is located between the secondary cylinder 41 and the material pulling frame 402. The top of the material pulling plate 401, the material pulling frame 402 and the bottom of the lever plate 202 are all provided with grooves 403.

[0031] According to the above structure, the remaining sleeve with the outer sleeve removed is placed flat in the groove 403 at the top of the material puller 402, and the copper alloy sleeve connected to the outer wall of one end of the middle brass sleeve protrudes on one side of the material puller plate 401, that is, the material puller plate 401 is located on the side of the connection between the two. Press the control switch 101, the output end of the main cylinder 21 extends first, and one end of the lever 202 descends close to the material puller 402. The sleeve is clamped by the lever 202 and the material puller 402. After a few seconds, the time relay inside the control switch 101 controls the auxiliary cylinder 41 to retract its output end, which can drive the material puller plate 401 away from the material puller 402. Since the middle brass sleeve is easy to clamp and fix, the copper alloy sleeve connected to one end is pulled out by the locking and pulling action of the groove 403 at the top of the material puller plate 401.

[0032] The working principle of this utility model is as follows: the main cylinder 21 is triggered by the control switch 101, the solenoid valve of the main cylinder 21 is energized, the cylinder extends, and at the same time the time delay device, such as a time relay or PLC, is activated. Taking the time relay as an example, after receiving the trigger signal from the control switch 101, it starts timing (2-3 seconds). After the timing is completed, it outputs a signal to the auxiliary cylinder 41 to trigger the action. Since the support plate 203 is rotatably connected to the middle of the lever plate 1 201 and the lever plate 202 to form a lever, when the output end of the main cylinder 21 rises, it drives one end of the lever plate 1 201 and the lever plate 202 to rise, and the other end will fall, that is, the arc-shaped pressure plate 204 at one end of the lever plate 1 201 falls.

[0033] Furthermore, the layered valve sleeve in the valve core is slid into the U-shaped groove 301 from the side. The valve sleeve presses against the magnetic block 311, causing it to slide along the sliding groove 313 into the through hole 310. At this time, the outer flared edge of the outer sleeve is also placed flat in the flared edge groove 302. The hand continues to press on the side of the valve sleeve without moving. When the arc-shaped pressure plate 204 descends, it presses down on the protruding rod 307, causing the ejector rod 306 to descend. The arc shape of the arc-shaped pressure plate 204 can decompose the lateral force generated by the lever rotation into an effective force in the vertical direction, making the pressure distribution more uniform. When the ejector rod 306 descends, the spring column 304 retracts, and the limiting rod 303 moves down accordingly, limiting the angle of the ejector rod 306 to prevent it from sliding left and right during descent.

[0034] Furthermore, the sliding plate 308 and the magnetic suction plate 309 also descend. The like poles of the magnetic suction plate 309 and the magnetic suction block 311 are opposite each other and repel each other. When the magnetic suction plate 309 descends, its magnetic field passes through the through hole 310, pushing the magnetic suction block 311 and the non-magnetic plate 312 towards the receiving box 102. However, due to the hand pressing on the valve sleeve, the magnetic poles repel each other and cannot push the outer sleeve at this time. The ejector rod 306 descends and inserts into the inner sleeve of the valve sleeve. When the hand is released and the valve sleeve is no longer pressed, the ejector rod 306 presses down the middle brass sleeve fitted on the inner wall of the outer sleeve. This causes it to detach and fall onto the slope 103, and slide down the slope 103 into the receiving box 102. Further, pressing the control switch 101 causes the output end of the main cylinder 21 to retract, the arc-shaped pressure plate 204 to lift upward, and the ejector rod 306 to rise under the elastic force of the spring column 304. At this time, the outer sleeve is still located in the U-shaped groove 301. When the sliding plate 308 rises with the ejector rod 306, the magnetic field of the sliding plate 308 passes through the perforation 310 and repels the magnetic block 311. The magnetic block 311 starts to move through the non-magnetic plate 312, which can automatically push the outer sleeve of the valve sleeve outward.

[0035] Furthermore, the remaining sleeve, from which the outer sleeve has been removed, is placed flat in the groove 403 at the top of the material puller 402, with the copper alloy sleeve attached to one end of the middle brass sleeve protruding from one side of the material puller 401, i.e., the material puller 401 is located on one side of the connection between the two. Pressing the control switch 101 causes the output end of the main cylinder 21 to extend first, and one end of the lever 202 descends close to the material puller 402. The sleeve is clamped by the lever 202 and the material puller 402. After a few seconds, the time relay inside the control switch 101 controls the auxiliary cylinder 41 to retract its output end, which can drive the material puller 401 away from the material puller 402. Since the middle brass sleeve is easily clamped and fixed, the copper alloy sleeve attached to one end is pulled out by the engaging and pulling action of the groove 403 at the top of the material puller 401.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
