Description

Technical Field

[0001] This invention relates to the technical field of diesel engine disassembly equipment, specifically to a non-destructive disassembly device and method for diesel engine cylinder head valve seats. Background Technology

[0002] The intake and exhaust valve seats of diesel engine cylinder heads are generally inlaid. The operating temperature of the intake and exhaust valve seats of the cylinder head is relatively high, about 300-400℃. The valves move up and down frequently in the cylinder head at high speeds. The high-frequency movement under high temperature conditions leads to accelerated wear of the intake and exhaust valve seats, causing air leakage. Therefore, it is necessary to replace the valve seats in a timely manner.

[0003] Currently, most diesel engine valve seat removal methods involve welding an iron block onto the valve seat ring, then inserting an iron rod through the valve guide rod hole to knock the iron block and valve seat ring out together. The drawback of this method is that during the welding process, the cylinder head is subjected to localized high temperatures, which can easily cause cracks, rendering the cylinder head unusable and leading to increased costs and wasted resources. Therefore, we propose a non-destructive disassembly device and method for diesel engine cylinder head valve seats. Summary of the Invention

[0004] The purpose of this invention is to provide a non-destructive disassembly device and method for diesel engine cylinder head valve seats, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A non-destructive disassembly device for diesel engine cylinder head valve seats, including adjustable abutment parts, linkage parts, and hammering parts;

[0007] The adjustable abutment is used to extend into the valve seat to be disassembled and abut against the inner side of the valve seat to be disassembled. The linkage is located between the adjustable abutment and the striking member. The striking member is used to intermittently strike the linkage member, so that the linkage member drives the valve seat to be disassembled to detach from the diesel engine cylinder head.

[0008] A further improvement is that the adjustable abutment includes a mounting bracket, an outer cylinder mounted on the mounting bracket, and a movable cylinder movably inserted into the bottom end of the outer cylinder for extending into the valve seat to be disassembled. The top end of the movable cylinder extends into the outer cylinder and is provided with a U-shaped frame. An elastic element is provided between the lower end of the U-shaped frame and the inner wall of the top of the movable cylinder. A drive rod is rotatably provided inside the U-shaped frame. A screw is provided at the bottom of the drive rod. A frustum-shaped drive block is threaded onto the outer wall of the screw. A telescopic rod is provided between the drive block and the U-shaped frame. The outer wall of the drive block is fitted with contact blocks in a ring array for abutting against the inner side of the valve seat to be disassembled. The side of the contact block facing the drive block has a beveled edge that cooperates with the drive block. The outer end of the contact block movably penetrates the outer wall of the movable cylinder. An elastic element is provided between the contact block and the movable cylinder.

[0009] A further improvement is that the linkage includes a gear rotatably disposed in a movable opening on one side of the outer wall of the outer cylinder, with racks meshing on both sides of the gear, one rack being disposed on the outer wall of the U-shaped frame, and the other rack being disposed on the outer wall of the movable plate, the movable plate being slidably inserted into a support frame on the outer wall of the outer cylinder, and the outer wall of the movable plate being provided with a force-bearing part corresponding to the striking component.

[0010] A further improvement is that the striking component includes a connecting frame disposed on the outer wall of the outer cylinder, a bearing frame disposed on the inner side of the connecting frame, a connecting arm rotatably disposed in the bearing frame, and a hammer head disposed at one end of the connecting arm for striking the force-bearing part. A driving arm is disposed in the bearing frame below the connecting arm. One end of the driving arm is sleeved on the output end of the rotating device on the outer wall of the bearing frame, and the other end is provided with a roller. The connecting arm is provided with a protrusion that slides against the roller.

[0011] The rotating device drives the drive arm to intermittently contact the protrusion through the roller, causing the connecting arm to drive the hammer head to reciprocate in striking the force-bearing part.

[0012] A further improvement is that the force-bearing part includes a driving plate movably sleeved on the outside of the movable plate and attached to the bottom of the support frame, a T-shaped rod 1 disposed on the driving plate and movably passing through the support frame, a spring disposed on the outer wall of the T-shaped rod 1 and connected at one end to the T-shaped rod 1 and at the other end to the support frame, and a force-bearing column disposed on the driving plate and used to contact the hammer head. The force-bearing column is located on the outside of the support frame, and a triggering component is provided on the force-bearing column. The outer wall of the driving plate is provided with a clamping component for clamping the movable plate.

[0013] It also includes a control module. After receiving the hammer pressure signal, the trigger component sends a signal to the control module, which then controls the clamping component to clamp the movable plate. After the trigger component no longer receives the hammer pressure signal, it sends a signal to the control module, which then controls the clamping component to release the movable plate.

[0014] A further improvement is that the triggering component includes a cavity opened in the force-bearing column, a pressure sensor is provided on the bottom inner wall of the cavity, a T-shaped push rod is provided above the pressure sensor, the top end of the push rod passes through the top of the force-bearing column and extends to the outside of the force-bearing column for contact with the hammer head, and a spring is provided between the bottom of the push rod and the inner wall of the cavity.

[0015] A further improvement is that the clamping assembly is provided in two sets, respectively located on two opposite sides of the driving plate. The clamping assembly includes a frame on the driving plate, a connecting rod movably passing through the inner side of the frame, a permanent magnet block at one end of the connecting rod located inside the frame, and a friction block at the other end of the connecting rod corresponding to the side wall of the movable plate. An elastic element is provided between the permanent magnet block and one inner wall of the frame, and an electromagnetic block that attracts the permanent magnet block by electricity is provided on the other inner wall of the frame. Friction plates for contacting the friction blocks are embedded on both opposite outer walls of the movable plate.

[0016] The electromagnetic block is controlled by the control module to attract the permanent magnet block, so that the permanent magnet block drives the connecting rod to drive the friction block to contact the friction plate.

[0017] A further improvement is that the movable plate has a ratchet on one side of its outer wall relative to the rack, and an assembly frame is provided on the inner side of the connecting frame and below the driving plate. A locking rod is horizontally inserted on the assembly frame. One end of the locking rod is located between two adjacent ratchet teeth in the ratchet, and the other end is connected to the assembly frame by a spring. The ratchet and the locking rod are used to restrict the upward movement of the movable plate.

[0018] A further improvement is that the assembly frame is equipped with a horizontal rotating shaft and a vertical rotating shaft, which are connected by a bevel gear set. The horizontal rotating shaft and the rotating device are connected by a sprocket drive set. A rotating disk is rotatably fitted on the outer wall of the outer cylinder. The rotating disk and the vertical rotating shaft are connected by a gear set. A lubricant storage tank containing lubricant is provided on the rotating disk. A telescopic nozzle is connected to the bottom rotating shaft of the rotating disk. The telescopic nozzle is connected to the output end of the lubricant storage tank through a hose. A solenoid valve controlled by a control module is provided inside the telescopic nozzle. The telescopic nozzle is used to spray lubricant onto the connection between the valve seat and the diesel engine cylinder head to be disassembled.

[0019] The method for using a non-destructive disassembly device for diesel engine cylinder head valve seats includes the following steps:

[0020] S1: Fix the diesel engine cylinder head, then insert the bottom end of the movable cylinder into the valve seat to be removed, and then install the device in the designated position by the mounting bracket. By rotating the drive rod, the drive rod drives the screw to make the drive block move downward, and the drive block makes the contact block move outward to abut against the inside of the valve seat to be removed.

[0021] S2: Open the rotating device. The rotating device drives the drive arm. The drive arm, through the rollers, pushes the protrusion on the drive arm, which in turn drives the connecting arm to drive the hammer head to reciprocate to strike the force column. Before the hammer head contacts the force column, it first presses the push rod to press the pressure sensor. After receiving the pressure signal, the pressure sensor sends a signal to the control module, which causes the control module to control the solenoid block and solenoid valve to open. The opening of the solenoid block attracts the permanent magnet block, causing the friction block to be tightly attached to the friction plate. Then, the force column is struck by the hammer head, which drives the movable plate downward through the drive plate. The movable plate downward drives the rack through the gear. The rack drives the adjustable abutment to transmit an upward force to the valve seat that is abutted. After the hammer head separates from the force column, the push rod separates from the pressure sensor. After the pressure sensor does not receive the pressure signal, it sends a signal to the control module, which causes the control module to control the solenoid block and solenoid valve to close. The closing of the solenoid block causes the friction block to separate from the friction plate. Thus, the drive plate returns to its original position relative to the movable plate under the action of the T-shaped rod and the spring. This cycle continues until the cylinder head to be disassembled is removed from the diesel engine cylinder head.

[0022] S3: When the rotating equipment is working, the horizontal rotating shaft is driven by the sprocket drive group. The horizontal rotating shaft drives the vertical rotating shaft through the bevel gear group. The vertical rotating shaft drives the rotating disk through the gear group, so that the rotating disk drives the lubricating fluid storage tank to perform circumferential motion. At the same time, the solenoid valve opens and closes intermittently, so that the lubricating fluid in the lubricating fluid storage tank is intermittently sprayed through the telescopic nozzle to the connection between the valve seat to be disassembled and the diesel engine cylinder head.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1) This invention uses an adjustable abutment to extend into the valve seat to be disassembled and contact the inner side of the valve seat. Then, a striking component strikes the linkage component, which drives the adjustable abutment to intermittently push the valve seat upward to separate it from the diesel engine cylinder head. This method eliminates the need to weld an iron block to the valve seat, thus avoiding the cylinder head being subjected to localized high temperatures, which could cause the cylinder head to become unusable. It also reduces manual labor intensity and is easy to use. On the other hand, the linkage component intermittently transmits the impact force generated by the striking component to the adjustable abutment, so that the adjustable abutment evenly transmits an upward vibration force to the valve seat. This drives the valve seat upward to separate from the diesel engine cylinder head, and gradually loosens the connection between the valve seat and the diesel engine cylinder head, making it easier for the valve seat to move upward.

[0025] 2) The present invention also includes a lubricant storage tank, a rotating disk, a telescopic nozzle, and a solenoid valve. When the striking part and the linkage part work together to drive the adjustable abutment part to move, the rotating disk is also driven to rotate, and the lubricant in the lubricant storage tank is intermittently sprayed from the telescopic nozzle to the connection between the cylinder head and the valve seat. The lubricant seeps into the connection between the cylinder head and the valve seat for lubrication, which on the one hand facilitates the valve seat to be better separated from the cylinder head, and on the other hand reduces the damage to the connection during disassembly, so that a new valve seat can be installed at the connection later.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please see the appendix Figure 1 and appendix Figure 7

[0037] A non-destructive disassembly device for diesel engine cylinder head valve seats, including adjustable abutment parts, linkage parts, and hammering parts;

[0038] The adjustable abutment is used to extend into the valve seat to be removed and abut against the inner side of the valve seat. According to existing technology, such as the diesel engine cylinder head remanufacturing valve seat removal device disclosed in CN212978164U, the valve seat to be removed is annular, as shown in the attached... Figure 7 As shown, attached Figure 7 In the diagram, A represents the cylinder head and B represents the valve seat.

[0039] The linkage is located between the adjustable abutment and the striking component. The striking component is used to intermittently strike the linkage, causing the linkage to drive the valve seat to be disassembled to detach from the diesel engine cylinder head.

[0040] Please see the appendix Figure 2 - Appendix Figure 4

[0041] As a preferred embodiment, the adjustable abutment includes a mounting bracket 41, an outer cylinder 1 disposed on the mounting bracket 41, and a movable cylinder 2 movably inserted into the bottom end of the outer cylinder 1 for extending into the valve seat to be disassembled. After the movable cylinder 2 extends into the valve seat to be disassembled, the mounting bracket 41 can be fixed to the outside world by bolts, such as an outside workbench. The outer diameter of the movable cylinder 2 is smaller than the inner diameter of the valve seat to be disassembled.

[0042] The top of the movable cylinder 2 extends into the outer cylinder 1 and is provided with a U-shaped frame 3. An elastic element 8, such as a spring, is provided between the lower end of the U-shaped frame 3 and the inner wall of the top of the movable cylinder 2, for subsequently driving the movable cylinder 2 to return to its original position. A drive rod 4 is rotatably provided inside the U-shaped frame 3. The top of the drive rod 4 has a handwheel. A bearing is provided at the connection between the drive rod 4 and the U-shaped frame 3. A screw 7 is provided at the bottom of the drive rod 4. The bottom end of the screw 7 is connected to the inner wall of the bottom of the movable cylinder 2 by a bearing. A frustum-shaped drive block 5 is screwed into the outer wall of the screw 7. A telescopic mechanism is provided between the drive block 5 and the U-shaped frame 3. The rod, through the telescopic rod, prevents the drive block 5 from rotating. The outer wall of the drive block 5 is provided with contact blocks 6 in a ring array for abutting against the inner side of the valve seat to be disassembled. There are several groups of contact blocks 6. The side of the contact block 6 facing the drive block 5 has a bevel that cooperates with the drive block 5. When the drive block 5 moves downward, it drives the contact blocks 6 to move outward. The outer end of the contact block 6 moves through the outer wall of the movable cylinder 2. An elastic element 2 9 is provided between the contact block 6 and the movable cylinder 2. The elastic element 2 9 is, for example, a spring. The elastic element 2 9 is used to keep the inner side of the contact block 6 always in contact with the outer wall of the drive block 5.

[0043] Preferably, the linkage in this embodiment includes a gear 11 rotatably disposed within a movable opening on one side of the outer wall of the outer cylinder 1. Both sides of the gear 11 are meshed with racks 12, one rack 12 is disposed on the outer wall of the U-shaped frame 3, and the other rack 12 is disposed on the outer wall of the movable plate 10. The movable plate 10 is slidably inserted into a support frame on the outer wall of the outer cylinder 1. The outer wall of the movable plate 10 is provided with a force-bearing portion corresponding to the striking component. When the striking component intermittently strikes the force-bearing portion, the force-bearing portion drives the movable plate 10 to move downward relative to the support frame. The movable plate 10 then drives the gear 11 via the racks 12, which in turn drives the U-shaped frame 3 upward. The U-shaped frame 3 then drives the movable cylinder 2 to move intermittently upward relative to the outer cylinder 1, providing an upward vibration force to the valve seat to be disassembled.

[0044] Please see the appendix Figure 5

[0045] As a preferred embodiment, the striking component includes a connecting frame 18 disposed on the outer wall of the outer cylinder 1, a bearing frame 19 disposed on the inner side of the connecting frame 18, a connecting arm 20 rotatably disposed in the bearing frame 19, and a hammer head 21 disposed at one end of the connecting arm 20 for striking the force-bearing part. Furthermore, the connecting arm 20 is disposed in the bearing frame 19 using a rotating shaft and a torsion spring.

[0046] A drive arm 24 is provided inside the support frame 19 below the connecting arm 20. One end of the drive arm 24 is sleeved on the output end of the rotating device 22 on the outer wall of the support frame 19, and the other end is provided with a roller 25. The connecting arm 20 is provided with a protrusion that slides against the roller 25.

[0047] The rotating device 22 drives the drive arm 24 to intermittently contact the protrusion through the roller 25, so that the connecting arm 20 drives the hammer head 21 to reciprocate to strike the force-bearing part.

[0048] Please see the appendix Figure 6

[0049] Preferably, the force-bearing part of this embodiment includes a driving plate 13 that is movably sleeved on the outside of the movable plate 10 and attached to the bottom of the support frame, a T-shaped rod 14 that is disposed on the driving plate 13 and movably passes through the support frame, a spring disposed on the outer wall of the T-shaped rod 14 with one end connected to the T-shaped rod 14 and the other end connected to the support frame, and a force-bearing column 15 disposed on the driving plate 13 for contacting the hammer head 21. The T-shaped rod 14 and the spring are used to subsequently drive the driving plate 13 to reset relative to the movable plate 10 and attach to the support frame.

[0050] The force-bearing column 15 is located on the outside of the support frame. The force-bearing column 15 is equipped with a triggering component, and the outer wall of the driving plate 13 is equipped with a clamping component for clamping the movable plate 10.

[0051] It also includes a control module. After receiving a pressure signal from the hammer head 21, the trigger component sends a signal to the control module, which then controls the clamping component to clamp the movable plate 10. Conversely, if the trigger component no longer receives a pressure signal from the hammer head 21, it sends a signal to the control module, which then controls the clamping component to release the movable plate 10. This configuration allows the force-bearing part to reciprocate, moving the movable plate 10 without changing its contact position with the hammer head 21.

[0052] Preferably, the triggering component in this embodiment includes a cavity opened in the force-bearing column 15. A pressure sensor 16 is provided on the inner wall of the bottom of the cavity. A T-shaped push rod 17 is provided above the pressure sensor 16. The top end of the push rod 17 passes through the top of the force-bearing column 15 and extends to the outside of the force-bearing column 15 for contact with the hammer head 21. A spring is provided between the bottom of the push rod 17 and the inner wall of the cavity. The spring is used to drive the push rod 17 to separate from the pressure sensor 16 when the hammer head separates from the push rod 17. Before the hammer head 21 contacts the force-bearing column 15, it will first squeeze the push rod 17 to contact the pressure sensor 16, so that when the hammer head 21 contacts the force-bearing column 15, the force-bearing column 15 can drive the driving plate 13 and the movable plate 10 to move downward.

[0053] Preferably, the clamping assembly of this embodiment has two sets, respectively located on two opposite sides of the driving plate 13. The clamping assembly includes a frame 36 on the driving plate 13. A connecting rod is movably passed through the inner side of the frame 36. A permanent magnet block 37 is provided at one end of the connecting rod inside the frame 36, and a friction block 38 is provided at the other end of the connecting rod corresponding to the side wall of the movable plate 10. An elastic element 40 is provided between the permanent magnet block 37 and one inner wall of the frame 36. An electromagnetic block 39 is provided on the other inner wall of the frame 36 to attract the permanent magnet block 37. Friction pieces 23 for contacting the friction blocks 38 are embedded on the two opposite outer walls of the movable plate 10. Both the friction blocks 38 and the friction pieces 23 can be made of wear-resistant rubber material. When the electromagnetic block 39 is not energized, the friction pieces 23 and the friction blocks 38 are in a non-contact state, and the driving plate 13 can move relative to the movable plate 10. When the electromagnetic block 39 is energized, the friction pieces 23 and the friction blocks 38 are in contact, and the driving plate 13 can drive the movable plate 10 to move.

[0054] The electromagnetic block 39 is controlled by the control module to attract the permanent magnet block 37, so that the permanent magnet block 37 drives the connecting rod to drive the friction block 38 to contact the friction plate 23.

[0055] To prevent the movable plate 10 from resetting upwards when the friction block 38 separates from the friction plate 23, it is preferred that the movable plate 10 in this embodiment has a ratchet 26 on one side of its outer wall relative to the rack 12. An assembly frame 27 is provided on the inner side of the connecting frame 18 and below the driving plate 13. A locking rod 28 is horizontally inserted on the assembly frame 27. One end of the locking rod 28 is located between two adjacent ratchet teeth in the ratchet 26, and the other end is connected to the assembly frame 27 by a spring. The ratchet 26 and the locking rod 28 are used to restrict the upward movement of the movable plate 10. When the movable plate 10 moves downwards, the ratchet 26 moves downwards relative to the locking rod 28. The ratchet teeth on the locking rod 28 and the ratchet teeth on the ratchet 26 restrict the upward movement of the movable plate 10.

[0056] Preferably, in this embodiment, the assembly frame 27 is provided with a horizontal rotating shaft and a vertical rotating shaft, which are connected by a bevel gear set 29. The bevel gear set 29 consists of two sets of meshing bevel gears. The horizontal rotating shaft and the rotating device 22 are connected by a sprocket drive set 30, which includes a sprocket and a chain. A rotating disk 31 is rotatably mounted on the outer wall of the outer cylinder 1. The rotating disk 31 and the vertical rotating shaft are connected by a gear set 32, which includes a gear ring mounted on the outer wall of the rotating disk 31 and a drive gear mounted on the vertical rotating shaft. The rotating disk 31 is provided with a lubricant storage cylinder 33 containing lubricant. A telescopic nozzle 34 is connected to the bottom rotating shaft on the turntable 31. The telescopic nozzle 34 is existing technology and its length can be changed. The telescopic nozzle 34 is located above the connection between the diesel engine cylinder head and the valve seat. The telescopic nozzle 34 is connected to the output end of the lubricant reservoir 33 through a hose. The telescopic nozzle 34 is equipped with a solenoid valve 35 controlled by the control module. The telescopic nozzle 34 is used to spray lubricant onto the connection between the valve seat to be disassembled and the diesel engine cylinder head. The lubricant seeps into the connection between the valve seat to be disassembled and the diesel engine cylinder head, making it easier to remove the valve seat from the diesel engine cylinder head and reducing the damage to the cylinder head caused by valve seat removal.

[0057] The method for using a non-destructive disassembly device for diesel engine cylinder head valve seats includes the following steps:

[0058] S1: Fix the diesel engine cylinder head, then insert the bottom end of the movable cylinder 2 into the valve seat to be removed, and then install the device in the designated position through the mounting bracket 41. By rotating the drive rod 4, the drive rod 4 drives the screw 7 to make the drive block 5 move downward, and the drive block 5 makes the contact block 6 move outward to abut against the inside of the valve seat to be removed.

[0059] S2: The rotating device 22 is turned on, which drives the drive arm 24. The drive arm 24, through the roller 25, pushes the protrusion on the drive arm 24, which drives the connecting arm 20 to drive the hammer head 21 to reciprocate and strike the force-bearing column 15. Before the hammer head 21 contacts the force-bearing column 15, it first presses the top rod 17 to press the pressure sensor 16. After receiving the pressure signal, the pressure sensor 16 sends a signal to the control module, which causes the control module to control the solenoid block 39 and the solenoid valve 35 to open. The solenoid block 39 opens and attracts the permanent magnet block 37, so that the friction block 38 is in close contact with the friction plate 23. Then the force-bearing column 15 is struck by the hammer head 21, which drives the movable plate 1 through the drive plate 13. 0 downwards, the movable plate 10 downwards drives the rack 12 through the gear 11, the rack 12 drives the adjustable abutment to drive the abutted valve seat upwards, after the hammer 21 separates from the force column 15, the push rod 17 separates from the pressure sensor 16, after the pressure sensor 16 does not receive a pressure signal, it sends a signal to the control module, so that the control module controls the solenoid block 39 and the solenoid valve 35 to close. The closing of the solenoid block 39 causes the friction block 38 to separate from the friction plate 23, thereby driving the plate 13 to return to its original position relative to the movable plate 10 under the action of the T-shaped rod 14 and the spring. This cycle continues until the cylinder head to be disassembled is removed from the diesel engine cylinder head.

[0060] S3: When the rotating equipment 22 is working, it also drives the horizontal rotating shaft through the sprocket transmission group 30. The horizontal rotating shaft drives the vertical rotating shaft through the bevel gear group 29. The vertical rotating shaft drives the rotating disk 31 through the gear group 32, so that the rotating disk 31 drives the lubricating fluid storage tank 33 to perform circumferential motion. At the same time, the solenoid valve 35 opens and closes intermittently, so that the lubricating fluid in the lubricating fluid storage tank 33 is sprayed through the telescopic nozzle 34 to the connection between the valve seat to be disassembled and the diesel engine cylinder head.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The ratchet (26) and the locking rod (28) are used to restrict the movable plate (10) from moving upward.

5. The method of using the non-destructive disassembly device for diesel engine cylinder head valve seats according to claim 4, characterized in that: Includes the following steps: S1: Fix the diesel engine cylinder head, then insert the bottom end of the movable cylinder (2) into the valve seat to be removed, and then install the device in the designated position by the mounting bracket (41). By rotating the drive rod (4), the drive rod (4) drives the screw (7) to make the drive block (5) move downward, and the drive block (5) makes the contact block (6) move outward to abut against the inside of the valve seat to be removed. S2: Turn on the rotating device (22). The rotating device (22) drives the drive arm (24). The drive arm (24) pushes the protrusion on the drive arm (24) through the roller (25), which drives the connecting arm (20) to drive the hammer head (21) to reciprocate to strike the force column (15). Before the hammer head (21) contacts the force column (15), it first presses the top rod (17) to press the pressure sensor (16). After receiving the pressure signal, the pressure sensor (16) sends a signal to the control module, which causes the control module to control the electromagnetic block (39) and the solenoid valve (35) to open. The electromagnetic block (39) opens and attracts the permanent magnet block (37), so that the friction block (38) is in close contact with the friction plate (23). Then the force column (15) is struck by the hammer head (21) and driven by the drive plate (13). The movable plate (10) moves downward, and the movable plate (10) moves downward through the gear (11) to drive the rack (12). The rack (12) drives the adjustable abutment to transmit an upward force to the valve seat being abutted. After the hammer (21) separates from the force column (15), the push rod (17) separates from the pressure sensor (16). After the pressure sensor (16) does not receive a pressure signal, it sends a signal to the control module, so that the control module controls the solenoid block (39) and the solenoid valve (35) to close. The closing of the solenoid block (39) causes the friction block (38) to separate from the friction plate (23), thereby driving the plate (13) to return to its original position relative to the movable plate (10) under the action of the T-shaped rod (14) and the spring. This cycle continues until the cylinder head to be disassembled is removed from the diesel engine cylinder head. S3: When the rotating equipment (22) is working, the horizontal rotating shaft is driven by the sprocket transmission group (30). The horizontal rotating shaft drives the vertical rotating shaft through the bevel gear group (29). The vertical rotating shaft drives the rotating disk (31) through the gear group (32). The rotating disk (31) drives the lubricating fluid storage tank (33) to perform circumferential motion. At the same time, the solenoid valve (35) opens and closes intermittently, so that the lubricating fluid in the lubricating fluid storage tank (33) is intermittently sprayed through the telescopic nozzle (34) to the connection between the valve seat to be disassembled and the diesel engine cylinder head.
