Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology, specifically relating to a non-destructive pneumatic valve core disassembly device. Background Technology

[0002] The hydraulic control module of the automatic transmission is the valve body (also known as the automatic transmission valve body assembly). By adjusting the oil pressure and flow direction, it controls the engagement and disengagement of shift actuators (such as clutches and brakes), thereby realizing the function of automatically switching gears according to parameters such as engine load and vehicle speed. The valve core is the "execution core" of the hydraulic control module valve body, which changes the oil passage inside the valve body by moving (such as lifting or rotating).

[0003] In the existing technology, when removing the valve core from the valve body, it is generally necessary to use tools such as screwdrivers and pry bars to insert into the gap between the valve core and the valve body, pry the valve core away from the valve body, or clamp the exposed part of the valve core and rotate or pull it out directly. However, when using tools to pry, the sealing surface is easily scratched, and uneven force may cause deformation of the locking groove. In addition, the valve core has a spring structure, and sudden release of tension may cause the tool to slip or cause injury. Utility Model Content

[0004] The purpose of this utility model is to provide a non-destructive pneumatic valve core disassembly device. The valve body is fixed by a servo cylinder and a fixing groove, and pressure is applied evenly to avoid shaking during disassembly. Air pressure is injected into the valve body through the air blowing hole via the air valve switch to gradually release the valve core clamping force. No tools are needed to pry it open, and the pressure release is controllable. This avoids scraping the valve core seals, prevents the clamping groove from deforming due to prying, and also prevents the spring mechanism inside the valve core from flying off and injuring people due to sudden release of tension.

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

[0006] A non-destructive pneumatic valve core disassembly device includes a first placement platform. Support rods are fixedly connected in an array on both the upper and lower sides of the first placement platform. The upper ends of several support rods are fixedly connected to a second placement platform, which is located above the first placement platform. A servo cylinder is fixedly assembled on the top of the second placement platform. A valve switch is provided through the bottom of the first placement platform. Several air blowing holes are asymmetrically distributed on the inner side of the first placement platform, and each air blowing hole is interconnected inside. A fixing groove is provided on the top of the first placement platform to limit the workpiece offset. A linkage retraction and blocking mechanism is provided on one side of the first and second placement platforms for limiting and blocking the workpiece and ejecting it for unloading.

[0007] The bottom side of the second placement platform is symmetrically fixedly connected with a vertical rod, and the first placement platform has a cut on the side near the vertical rod, with wedge blocks symmetrically fixedly connected to the side wall of the cut.

[0008] The linkage retraction mechanism includes an L-shaped baffle and a sliding plate. The L-shaped baffle is slidably connected to the vertical rod, and the top end of the L-shaped baffle is fixedly connected to the output end of the servo cylinder.

[0009] The L-shaped baffle is fixedly connected to two sides with wedge plates, and the sliding plate is symmetrically fixedly connected to the side wall with sliding rods. The sliding plate is slidably connected to the first placement platform through the sliding rods, and the sliding plate is slidably disposed on one side of the cut.

[0010] The sliding plate has an inner cavity, and a lifting plate is slidably connected to the inner wall of the inner cavity. The top of the lifting plate is set as an inclined surface, and several levers are fixedly connected to the top of the lifting plate. Secondary spring columns are fixedly connected at equal intervals to the bottom of the inner cavity. One end of each secondary spring column is fixedly connected to the lifting plate. The top of the sliding plate has a slot for the levers to pass through.

[0011] The sliding plate has a symmetrical through hole in the middle for the wedge block to be inserted, and the top slope of the lifting plate is parallel to the central axis of the through hole. Two wedge plates are fixedly connected to both ends of the sliding plate.

[0012] Limiting rods are fixedly connected to both ends of the cut. A connecting head is slidably sleeved on the outer wall of the limiting rod. A main spring column is sleeved on the outer side of the limiting rod. The connecting head is elastically connected to the cut through the main spring column. A connecting rod is fixedly connected to the side wall of the connecting head. One end of the connecting rod is fixedly connected to the second wedge plate.

[0013] The technical effects achieved by this utility model are as follows: the valve body is fixed by a servo cylinder and a fixed groove, and pressure is applied evenly to avoid shaking during disassembly. Air pressure is injected into the valve body through the air blowing hole via the air valve switch to gradually release the valve core locking force without the need for prying with tools. The pressure release is controllable, avoiding scraping of the valve core seal and preventing deformation of the locking groove due to prying. It also prevents the spring mechanism inside the valve core from flying off and injuring people due to sudden release of tension. Attached Figure Description

[0022] 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.

[0023] like Figures 1-4 As shown, a non-destructive pneumatic valve core disassembly device includes a first placement platform 1. Support rods 101 are fixedly connected in an array to both the upper and lower sides of the first placement platform 1. A second placement platform 102 is fixedly connected to the upper ends of several support rods 101. The second placement platform 102 is located above the first placement platform 1. A servo cylinder 103 is fixedly assembled on the top of the second placement platform 102. A valve switch 104 is provided through the bottom of the first placement platform 1. Several air holes 105 are asymmetrically distributed inside the first placement platform 1, and each air hole 105 is interconnected internally. A fixing groove is provided on the top of the first placement platform 1. 106, used to limit workpiece offset, a vertical rod 107 is symmetrically fixedly connected to one side of the bottom of the second placement platform 102, and a slit 108 is opened on the side of the first placement platform 1 near the vertical rod 107. A wedge block 109 is symmetrically fixedly connected to the side wall of the slit 108. A linkage retraction and blocking mechanism is provided on one side of the first placement platform 1 and the second placement platform 102 for limiting and blocking the workpiece and ejecting and unloading. The linkage retraction and blocking mechanism includes an L-shaped baffle 2 and a sliding plate 3. The L-shaped baffle 2 is slidably connected to the vertical rod 107, and the top end of the L-shaped baffle 2 is simultaneously fixedly connected to the output end of the servo cylinder 103.

[0024] According to the above structure, the support rod 101 provides support for the first placement platform 1 and the second placement platform 102, places the valve body on the first placement platform 1, and makes the protrusion of the valve body fit into the fixing groove 106 to prevent the valve body from horizontally displacing. The servo cylinder 103 is activated so that its output end descends and presses against the top of the valve body to prevent the valve body from vertically displacing. By pressing the open air valve switch 104, the airflow can enter the air blowing hole 105 through the air valve switch 104. Since the air blowing holes 105 are interconnected inside the first placement platform 1, the airflow can be sprayed onto the valve body from multiple air blowing holes 105 at the same time. The air pressure flows through the oil passage groove inside the valve body and pushes the valve core outward. The locking part of the valve core gradually moves under the push of the air pressure, and the tension of the spring mechanism inside it is gradually released. When the output end of the servo cylinder 103 descends, it will also drive the L-shaped baffle 2 to descend together. The vertical rod 107 provides auxiliary support for the L-shaped baffle 2 and ensures that it can slide vertically.

[0025] See attached document Figures 3-6 Wedge-shaped plates 201 are fixedly connected to both sides of the L-shaped baffle 2. Slide rods 306 are symmetrically fixedly connected to the side walls of the sliding plate 3. The sliding plate 3 is slidably connected to the first placement platform 1 through the slide rods 306. The sliding plate 3 is slidably positioned on one side of the cut 108. An inner cavity 301 is formed inside the sliding plate 3. A lifting plate 302 is slidably connected to the inner wall of the inner cavity 301. The top of the lifting plate 302 is set as an inclined surface. Several levers 303 are fixedly connected to the top of the lifting plate 302. Secondary spring columns 304 are fixedly connected at equal intervals to the bottom of the inner cavity 301. One end of each secondary spring column 304 is fixedly connected to the lifting plate 302. A lever for feeding is formed on the top of the sliding plate 3. The sliding plate 3 has a through-hole groove through which the sliding plate 3 passes. A through-hole 305 is symmetrically opened in the middle of the sliding plate 3 for the wedge block 109 to be embedded. The top slope of the lifting plate 302 is parallel to the central axis of the through-hole 305. The two ends of the sliding plate 3 are fixedly connected to the second wedge plate 307. The two ends of the cut 108 are fixedly connected to the limit rod 310. The outer wall of the limit rod 310 is slidably sleeved with the connecting head 309. The outer side of the limit rod 310 is sleeved with the main spring column 308. The connecting head 309 is elastically connected to the cut 108 through the main spring column 308. The side wall of the connecting head 309 is fixedly connected to the connecting rod 311. One end of the connecting rod 311 is fixedly connected to the second wedge plate 307.

[0026] According to the above structure, when the L-shaped baffle 2 descends, the first wedge plate 201 begins to push the second wedge plate 307 towards the cut 108. When the L-shaped baffle 2 descends to one side of the cut 108, and according to the L-shaped structure of the L-shaped baffle 2, the top of the L-shaped baffle 2 is located above the valve body, and the side panel of the L-shaped baffle 2 is located in the direction in which the valve core is pushed out. This can block the valve core components when the valve core is pushed out by air pressure, preventing the components from flying off in all directions. The second wedge plate 307... When the sliding plate 3 is pushed towards the cut 108 by the wedge plate 201, the sliding plate 3 and the sliding rod 306 move synchronously. The wedge plate 307 also drives the connecting head 309 to move along the axis of the limiting rod 310 through the connecting rod 311. The main spring column 308 begins to retract. The limiting rod 310 can prevent the sliding plate 3 and the connecting head 309 from shaking or shifting during movement. When the sliding plate 3 moves and fits against the cut 108, the wedge block 109 passes through the perforation 305 and enters the inner cavity 301. The inclined surface of 109 presses down on the inclined surface at the top of the lifting plate 302, causing it to move downwards. This causes the lever plate 303 to retract into the inner chamber 301, and the auxiliary spring column 304 begins to retract. Because the lever plate 303 retracts into the inner chamber 301, it avoids obstructing the valve core when it is pushed out. After the valve core is pushed out of the valve body, the air valve switch 104 is closed, and the servo cylinder 103 is activated to raise its output end. The servo cylinder 103 drives the L-shaped baffle 2 to rise. After the L-shaped baffle 2 rises... Wedge plate 307 is no longer compressed, and sliding plate 3 moves away from cut 108 under the rebound of main spring column 308. When sliding plate 3 moves, wedge block 109 disengages from through hole 305, and lifting plate 302 is no longer compressed. It rises under the rebound of secondary spring column 304, thereby causing the lever plate 303 to rise and protrude. After the lever plate 303 protrudes, it is located on the side of the valve core that has been pushed out. The lever plate 303 moves away from cut 108 under the movement of sliding plate 3, thereby completely taking the valve core out of the valve body.

[0027] This utility model uses a servo cylinder 103 to fix the valve body with a fixing groove 106, applying pressure evenly to avoid shaking during disassembly. Air pressure is injected into the valve body through the air valve switch 104 and the air blowing hole 105 to gradually release the valve core locking force. No tools are needed to pry it open, and the pressure release is controllable, avoiding scraping the valve core seal and preventing the locking groove from deforming due to prying. It also prevents the spring mechanism inside the valve core from flying off and injuring people due to sudden release of tension.

[0028] The working principle of this utility model is as follows: the support rod 101 provides support for the first placement platform 1 and the second placement platform 102, the valve body is placed on the first placement platform 1, and the protrusion of the valve body is engaged with the fixing groove 106 to prevent the valve body from horizontally displacing. The servo cylinder 103 is activated so that its output end descends and presses against the top of the valve body to prevent the valve body from vertically displacing. By pressing the open air valve switch 104, the airflow can enter the air blowing hole 105 through the air valve switch 104. Since the air blowing holes 105 are interconnected inside the first placement platform 1, the airflow can be sprayed onto the valve body from multiple air blowing holes 105 at the same time. The air pressure flows through the oil passage groove inside the valve body and pushes the valve core outward. The locking part of the valve core gradually moves under the push of the air pressure, and the tension of the spring mechanism inside it is gradually released. When the output end of the servo cylinder 103 descends, it will also drive the L-shaped baffle 2 to descend together.

[0029] Furthermore, the vertical rod 107 provides auxiliary support for the L-shaped baffle 2 and ensures that it can slide vertically; when the L-shaped baffle 2 descends, the wedge plate 201 begins to push the wedge plate 307 to move towards the cut 108. When the L-shaped baffle 2 descends to the side of the cut 108, according to the L-shaped structure of the L-shaped baffle 2, the top of the L-shaped baffle 2 is located above the valve body, and the side panel of the L-shaped baffle 2 is located in the direction in which the valve core is pushed out. It can block the valve core components when the valve core is pushed out by air pressure, preventing the components from flying off in all directions.

[0030] Furthermore, when the second wedge plate 307 is pushed towards the cut 108 by the first wedge plate 201, the sliding plate 3 and the sliding rod 306 move synchronously. The second wedge plate 307 will also drive the connecting head 309 to move along the axis of the limiting rod 310 through the connecting rod 311. The main spring column 308 begins to retract. The limiting rod 310 can prevent the sliding plate 3 and the connecting head 309 from shaking or shifting during movement. When the sliding plate 3 moves and fits against the cut 108, the wedge block 109 passes through the through hole 305 and enters the inner cavity 301. The inclined surface of the wedge block 109 presses the inclined surface at the top of the lifting plate 302, causing it to move downward, driving the lever plate 303 to retract into the inner cavity 301. The secondary spring column 304 begins to retract. Since the lever plate 303 retracts into the inner cavity 301, it can prevent the lever plate 303 from blocking the valve core when it is pushed out.

[0031] Furthermore, after the valve core is pushed out of the valve body, the air valve switch 104 is closed, and the servo cylinder 103 is activated to raise its output end. The servo cylinder 103 drives the L-shaped baffle 2 to rise. After the L-shaped baffle 2 rises, the wedge plate 2 307 is no longer squeezed, and the sliding plate 3 moves away from the cut 108 under the rebound of the main spring column 308. When the sliding plate 3 moves, the wedge block 109 disengages from the through hole 305, and the lifting plate 302 is no longer squeezed. It rises under the rebound of the secondary spring column 304, thereby causing the lever plate 303 to rise and protrude. After the lever plate 303 protrudes, it is located on the side of the pushed-out valve core. The lever plate 303 moves away from the cut 108 under the movement of the sliding plate 3, thereby completely pulling the valve core out of the valve body.

[0032] 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.
