Abstract
Description
Technical Field
[0001] This utility model relates to the field of diesel engine cylinder head valve port disassembly technology, and in particular to a diesel engine cylinder head valve port disassembly device. Background Technology
[0002] The diesel engine cylinder head is tightly integrated with the small cylinder block to form a closed combustion chamber. During the operation of the diesel engine, the cylinder head must be able to withstand the high temperature and high pressure of the gas in the combustion chamber to prevent gas leakage. The diesel engine cylinder head valve port is divided into an intake valve port and an exhaust valve port. The main function of the diesel engine cylinder head valve port is to open during the intake stroke to allow fresh air or pressurized air to enter the combustion chamber at a suitable flow rate and volume.
[0003] Currently, when disassembling the cylinder head valve port of a diesel engine, it is usually necessary for two operators to work together to use an ejector mold to push the cylinder head valve port out by striking it. However, striking will generate a certain impact force, which may cause damage such as dents and scratches on the surface of the cylinder head valve port, thereby increasing the risk of damage to the cylinder head valve port. Utility Model Content
[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a diesel engine cylinder head valve port disassembly device, which can easily disassemble the cylinder head valve port. The disassembly process can be carried out by only one operator, and there is no need to use a hammering method to push the valve port out, reducing the risk of damage to the parts due to improper force.
[0005] To achieve the above objectives, this utility model also provides a diesel engine cylinder head valve port disassembly device, comprising: a diesel engine body, a support plate movably connected to the upper surface of the diesel engine body, a top plate fixedly connected to the upper surface of the support plate, an internally threaded sleeve fixedly connected to the upper surface of the top plate, a threaded screw threadedly connected to the inner surface of the internally threaded sleeve, a rotating handle fixedly connected to the upper end of the threaded screw, a sleeve fixedly connected to the side surface of the threaded screw, a circular iron block fixedly connected to the lower surface of the sleeve, a small cylinder fixedly connected to the upper surface of the circular iron block, and a limit block fixedly connected to the output end of the small cylinder.
[0006] According to the diesel engine cylinder head valve port disassembly device, the lower surface of the limiting block is slidably connected to the circular iron block, and the small cylinder is electrically connected to an external power source. By starting the small cylinder, the limiting block is moved so that the end of the limiting block away from the small cylinder is in close contact with the cylinder head valve port. At the same time, the movement of the limiting block can make close contact with cylinder head valve ports of different sizes. By rotating the threaded screw with the handle, the threaded screw, sleeve, circular iron block, small cylinder, limiting block and cylinder head valve port are moved upward under the action of the internal threaded sleeve, so that the cylinder head valve port can be disassembled from the groove.
[0007] According to the diesel engine cylinder head valve port disassembly device, the number of small cylinders and limiting blocks is multiple and distributed in a ring. The multiple limiting blocks increase the contact area between one end of the limiting block and the cylinder head valve port, thereby enabling better disassembly of the cylinder head valve port.
[0008] According to the diesel engine cylinder head valve port disassembly device, a connecting plate is fixedly connected to the lower surface of the top plate, and an electric telescopic rod is fixedly connected to the left surface of the connecting plate.
[0009] According to the diesel engine cylinder head valve port disassembly device, the electric telescopic rod is electrically connected to an external power source, and a limit plate is fixedly connected to the left surface of the electric telescopic rod.
[0010] According to the diesel engine cylinder head valve port disassembly device, an anti-slip pad is fixedly connected to the left surface of the limiting plate. By activating the electric telescopic rod to move the limiting plate and the anti-slip pad, the positions of components such as the support plate, top plate, and threaded screw will not shift during use, thereby increasing the stability of the disassembly device structure.
[0011] According to the diesel engine cylinder head valve port disassembly device, a handle is fixedly connected to the upper surface of the diesel engine body. There are two support plates and two handles, which are distributed on the left and right sides. The disassembly structure can be moved more conveniently through the handles.
[0012] According to the diesel engine cylinder head valve port disassembly device, a groove is provided inside the diesel engine body, and a cylinder head valve port is disposed inside the groove.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] By setting up a support plate, top plate, internal threaded sleeve, threaded screw, handle, sleeve, round iron block, small cylinder and limit block, the cylinder head valve port can be easily disassembled. The disassembly process can be carried out by only one operator, and there is no need to use hammering to push the valve port out, which reduces the risk of damage to the parts due to improper force. Moreover, it can disassemble cylinder head valve ports of different sizes, making the structure more versatile.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Reference Figure 1-4 This utility model discloses a diesel engine cylinder head valve port disassembly device, comprising: a diesel engine body 1, a support plate 2 movably connected to the upper surface of the diesel engine body 1, a top plate 3 fixedly connected to the upper surface of the support plate 2, an internally threaded sleeve 4 fixedly connected to the upper surface of the top plate 3, a threaded screw 5 threadedly connected to the inner surface of the internally threaded sleeve 4, a rotating handle 6 fixedly connected to the upper end of the threaded screw 5, a sleeve 7 fixedly connected to the side surface of the threaded screw 5, a circular iron block 8 fixedly connected to the lower surface of the sleeve 7, a small cylinder 9 fixedly connected to the upper surface of the circular iron block 8, the small cylinder 9 being electrically connected to an external power source, a limiting block 10 fixedly connected to the output end of the small cylinder 9, the lower surface of the limiting block 10 being slidably connected to the circular iron block 8, and multiple small cylinders 9 and limiting blocks 10 arranged in a ring.
[0025] A connecting plate 11 is fixedly connected to the lower surface of the top plate 3. An electric telescopic rod 12 is fixedly connected to the left surface of the connecting plate 11. The electric telescopic rod 12 is electrically connected to an external power source. A limit plate 13 is fixedly connected to the left surface of the electric telescopic rod 12. An anti-slip pad 14 is fixedly connected to the left surface of the limit plate 13. A groove 15 is provided inside the diesel engine body 1.

There are two support plates 2 and two handles 17, which are distributed on the left and right sides.
[0026] Working principle: During use, the structure can be moved by handle 17, placing the disassembly device directly above the cylinder head valve port 16 to be disassembled. The support plate 2 supports the disassembly device. By activating the electric telescopic rod 12, the limiting plate 13 and anti-slip pad 14 are moved, so that the anti-slip pad 14 contacts the diesel engine body 1, preventing the position of the support plate 2 from shifting during use. By rotating the handle 6, the threaded screw 5, sleeve 7, and round iron block 8 are moved down into the cylinder head valve port 16 under the action of the internal threaded sleeve 4. The small cylinder 9 is activated, moving the limiting block 10 so that the end of the limiting block 10 away from the small cylinder 9 is in close contact with the inner wall of the cylinder head valve port 16. Multiple small The inclusion of cylinder 9 and limit block 10 increases the contact area between limit block 10 and cylinder head valve port 16. By rotating handle 6 in the opposite direction, the threaded screw 5, sleeve 7, circular iron block 8, small cylinder 9, limit block 10, and cylinder head valve port 16 are moved upward under the action of internal thread sleeve 4, thus removing cylinder head valve port 16 from the inner groove 15 of diesel engine block 1. This structure allows for easy removal of cylinder head valve port 16, requiring only one operator to disassemble it. Furthermore, it eliminates the need for hammering to push cylinder head valve port 16 out, reducing the risk of damage due to improper force. It also allows for the disassembly of cylinder head valve ports 16 of different sizes, making this structure more versatile.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
