DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, this embodiment provides an embodiment of a quickly assembled ship engine cylinder head.

[0025] A quickly assembled ship engine cylinder head comprises an engine casing 1 and a cylinder head body 2. The engine casing 1 is provided with a positioning structure 3, the positioning structure 3 comprises a plurality of clamping blocks 4 mounted on the top of the engine casing 1, the clamping blocks 4 are provided with positioning grooves 5, a plurality of clamping grooves 6 are evenly provided on the cylinder head body 2, and positioning blocks 7 are fixedly installed inside the clamping grooves 6. By setting the positioning structure 3, when the engine housing 1 and the cylinder head body 2 are assembled, the cylinder head body 2 is covered on the top of the engine housing 1. At this time, the multiple clamping blocks 4 set on the top of the engine housing 1 extend to the clamping groove 6 opened at the bottom of the cylinder head body 2 for preliminary positioning. When the cylinder head body 2 is fitted with the engine housing 1, the positioning block 7 in the clamping groove 6 is engaged with the positioning groove 5 opened on the clamping block 4. Under the engagement of the positioning block 7 and the positioning groove 5, the engine housing 1 and the cylinder head body 2 are finally accurately positioned. After double positioning, the cylinder head body 2 can be prevented from sliding off the engine housing 1, so that the threaded holes on the engine housing 1 and the cylinder head body 2 can be quickly aligned, thereby facilitating the rapid installation of multiple bolts and improving the assembly efficiency.

[0026] A guide block 8 is installed at one end of the positioning block 7. One end of the guide block 8 is set to be conical. A screw rod 9 is fixedly installed on one side of the guide block 8. A first installation groove 10 used in conjunction with the screw rod 9 is opened on the positioning block 7. A sealing gasket 11 is set at the bottom of the cylinder head body 2. Through the setting of the guide block 8, and one end of the guide block 8 is conical, since the contact area of ​​the conical end of the guide block 8 is small, when the engine housing 1 and the cylinder head body 2 are assembled, the guide block 8 can play a pulling role on the positioning block 7, so that the positioning block 7 can be more accurately and easier to insert into the positioning groove 5, further improving the speed and accuracy of the assembly of the engine housing 1 and the cylinder head body 2. Through the setting of the screw rod 9 and the first installation groove 10, when repairing the internal parts of the engine housing 1, the engine housing 1 and the cylinder head body 2 need to be frequently disassembled and installed. After multiple installations, the guide block 8 will be damaged due to collision. At this time, since the guide block 8 is installed on the positioning block 7 through the screw 9 and the first installation groove 10, the guide block 8 can be directly removed from the positioning block 7 by rotating it, thereby facilitating the replacement of the guide block 8. Through the setting of the sealing gasket 11, not only can the connection between the engine housing 1 and the cylinder head body 2 be sealed, but also when the cylinder head body 2 falls and is spliced ​​with the engine housing 1, it can play a buffering role for the cylinder head body 2, thereby preventing the bottom of the cylinder head body 2 and the top of the engine housing 1 from being damaged.

[0027] The sealing gasket 11 is connected to the cylinder head body 2 by adhesive, and a plurality of empty slots 12 corresponding to the card slot 6 are provided on the sealing gasket 11. A plurality of second mounting slots 13 are provided on the top of the cylinder head body 2. Heat dissipation fins 14 are provided inside the second mounting slots 13. Fixing plates 15 are fixedly installed on both sides of the heat dissipation fins 14. The fixing plates 15 are connected to the inner wall of the second mounting slots 13 by bolts. By installing the sealing gasket 11 on the cylinder head body 2 by adhesive, it is effectively prevented from falling off. At the same time, the opening of the empty slots 12 facilitates the insertion of the card block 4 into the card slot 6. The provision of the second mounting slots 13 and the heat dissipation fins 14 can improve the heat dissipation performance. The fixing plates 15 and bolts are used to install and fix the heat dissipation fins 14, so that it is easy to disassemble and replace them.

[0028] In this embodiment, if Figure 1-Figure 5 As shown, the working process of a quickly assembled ship engine cylinder head provided by this embodiment is as follows:

[0029] When assembling the engine housing 1 and the cylinder head body 2, the cylinder head body 2 is covered on the top of the engine housing 1. At this time, multiple clamping blocks 4 set on the top of the engine housing 1 extend to the clamping groove 6 opened at the bottom of the cylinder head body 2 for preliminary positioning. When the cylinder head body 2 is fitted with the engine housing 1, the positioning block 7 in the clamping groove 6 is engaged with the positioning groove 5 opened on the clamping block 4. Under the engagement of the positioning block 7 and the positioning groove 5, the engine housing 1 and the cylinder head body 2 are finally accurately positioned. After double positioning, the cylinder head body 2 can be prevented from sliding off the engine housing 1, so that the threaded holes on the engine housing 1 and the cylinder head body 2 can be quickly aligned, thereby facilitating the rapid installation of multiple bolts.

[0030] In summary, in the present embodiment, according to a quickly assembled ship engine cylinder head of the present embodiment, the guide block 8 is provided, and one end of the guide block 8 is tapered. Since the contact area of ​​the tapered end of the guide block 8 is small, when the engine housing 1 and the cylinder head body 2 are assembled, the guide block 8 can pull the positioning block 7, so that the positioning block 7 can be more accurately and easily inserted into the positioning groove 5, further improving the speed and accuracy of the assembly of the engine housing 1 and the cylinder head body 2. Through the provision of the screw 9 and the first mounting groove 10, when repairing the internal parts of the engine housing 1, the engine housing 1 and the cylinder head body 2 need to be frequently disassembled and installed. After multiple installations, the guide block 8 will be damaged due to collision. At this time, since the guide block 8 is installed in the positioning groove 5 through the screw 9 and the first mounting groove 10 The guide block 8 is on the positioning block 7, so it can be removed from the positioning block 7 directly by rotating it, so as to facilitate the replacement of the guide block 8. Through the setting of the sealing gasket 11, not only the connection between the engine housing 1 and the cylinder head body 2 can be sealed, but also the cylinder head body 2 can be buffered when the cylinder head body 2 falls and is spliced ​​with the engine housing 1, so as to prevent the bottom of the cylinder head body 2 and the top of the engine housing 1 from being damaged. By installing the sealing gasket 11 on the cylinder head body 2 with an adhesive, it can be effectively prevented from falling off. At the same time, the opening of the empty groove 12 facilitates the insertion of the card block 4 into the card slot 6. By setting the second mounting groove 13 and the heat dissipation fin 14, the heat dissipation performance can be improved, and the fixing plate 15 and bolts are used to install and fix the heat dissipation fin 14, which can be convenient for disassembly and replacement.
