Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engines, in particular to a cylinder head structure. Background Art
[0002] In existing engine technology, the cylinder head is an important component of the engine. Its main function is to seal the upper part of the cylinder block and form a combustion chamber together with the piston, cylinder block and other components. Traditional cylinder heads are usually one-piece designs, that is, the entire cylinder head is composed of a single component. Although this design has the advantages of simple structure and easy manufacturing, it has some shortcomings in practical applications.
[0003] First, the one-piece cylinder head is cumbersome to install and disassemble, requiring a lot of time and manpower for precise alignment and tightening, resulting in low engine assembly and maintenance efficiency. Secondly, when a part of the cylinder head is damaged, the entire cylinder head often needs to be replaced, which not only increases maintenance costs and prolongs maintenance time, but also causes a waste of resources. In addition, the one-piece cylinder head also has the problems of large size and heavy weight during production and transportation, which brings inconvenience to logistics and warehousing. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a cylinder head structure.
[0005] The utility model is implemented by the following technical solution: a cylinder head structure includes a first cylinder head, first positioning grooves are opened on both sides of the outer surface of the first cylinder head, a first clamping block is inserted into the interior of the first positioning groove, the first cylinder head is clamped with a center cylinder head through the first positioning groove, and the first clamping block is fixedly connected to the outer surface of the center cylinder head.
[0006] Through the above technical solution, the device modularizes the cylinder head so that each part can be manufactured, maintained and replaced independently, which not only improves production efficiency but also reduces maintenance costs. The modular design allows a module to be disassembled and replaced individually when adjustment or maintenance is required without affecting other parts, reducing maintenance time and complexity.
[0007] As a further improvement of the above solution, second positioning grooves are provided on both sides of the outer surface of the central cylinder head, and second clamping blocks are inserted into the interior of the second positioning grooves.
[0008] As a further improvement of the above solution, the central cylinder head is clamped with the second cylinder head via a second positioning groove, and the second clamping block is fixedly connected to the outer surface of the second cylinder head.
[0009] Through the above technical solution, the first cylinder head, the middle cylinder head and the second cylinder head, each partial cylinder head is an independent module. When maintenance or replacement is required, it can be operated separately without affecting other modules, reducing the difficulty and time of maintenance.
[0010] As a further improvement of the above solution, both sides of the first cylinder head are fixedly connected with a first connecting seat, and both sides of the middle cylinder head are fixedly connected with a second connecting seat.
[0011] As a further improvement of the above solution, both sides of the second cylinder head are fixedly connected with a connecting seat three, and the interiors of the connecting seat one and the connecting seat two are penetrated by an upper latch rod.
[0012] Through the above technical solution, the connecting seats are connected and fixed by the upper latch rod, thereby fixing the first cylinder head and the center cylinder head.
[0013] As a further improvement of the above solution, a lower latch rod is passed through the interior of the connecting seat 2 and the connecting seat 3.
[0014] Through the above technical solution, the second connecting seat and the third connecting seat are connected and fixed by the lower latch rod, thereby strengthening the fixation of the center cylinder head and the second cylinder head.
[0015] As a further improvement of the above solution, both ends of the upper latch rod and the lower latch rod are threadedly connected with hexagonal bolts.
[0016] Through the above technical solution, the hexagonal bolts connected by threads can provide a reliable fastening effect, ensuring that the latch rod will not loosen during the connection process, thereby enhancing the stability of the entire cylinder head during connection.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] The utility model divides the cylinder head into three independent modules, namely the first cylinder head, the middle cylinder head and the second cylinder head, and adopts a dual fixing method of clipping and latching, thereby realizing rapid pre-installation and stable connection of the cylinder head. In addition, during daily maintenance, this modular design allows personnel to disassemble and replace specific modules separately without replacing the entire cylinder head. When a part of the cylinder head is damaged, only the damaged part needs to be replaced in a targeted manner, which can not only significantly reduce maintenance costs and time, but also effectively avoid waste of resources.

[0026] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Example:
[0028] Please combine Figure 1-5 , a cylinder head structure of the present embodiment includes a first cylinder head 1, and first positioning grooves 2 are opened on both sides of the outer surface of the first cylinder head 1, and a first clamping block 3 is inserted into the inside of the first positioning groove 2. The first cylinder head 1 is clamped with the center cylinder head 4 through the first positioning groove 2, and the first clamping block 3 is fixedly connected to the outer surface of the center cylinder head 4. The personnel inserts the first clamping block 3 into the first positioning groove 2, so that the initial positioning of the first cylinder head 1 and the center cylinder head 4 can be achieved, ensuring that the relative position between the two parts of the cylinder head is accurate. During routine maintenance or replacement of parts, a module, such as the first cylinder head 1 or the center cylinder head 4, can be disassembled separately without affecting the normal operation of other parts, thereby simplifying the maintenance process and reducing maintenance costs and time.
[0029] Second positioning grooves 5 are provided on both sides of the outer surface of the central cylinder cover 4 , and second clamping blocks 6 are inserted into the second positioning grooves 5 .
[0030] The centered cylinder head 4 is clamped with the second cylinder head 7 through the second positioning groove 5, and the second clamping block 6 is fixedly connected to the outer surface of the second cylinder head 7. The personnel inserts the second clamping block 6 into the second positioning groove 5 to achieve the preliminary positioning of the centered cylinder head 4 and the second cylinder head 7. At this time, the pre-installation between the first cylinder head 1, the centered cylinder head 4 and the second cylinder head 7 is achieved. At this time, the three partial cylinder heads constitute an integral cylinder head.
[0031] Connecting seats 1 8 are fixedly connected to both sides of the first cylinder head 1 , and connecting seats 2 9 are fixedly connected to both sides of the middle cylinder head 4 .
[0032] Both sides of the second cylinder head 7 are fixedly connected with the connecting seat three 10, and the upper latch rod 11 passes through the interior of the connecting seat one 8 and the connecting seat two 9. The upper latch rod 11 connects the connecting seat one 8 and the connecting seat two 9 to be connected and fixed, thereby strengthening the fixation of the first cylinder head 1 and the center cylinder head 4 to avoid the cylinder head shaking due to external forces during subsequent use and the problem of unstable connection. The upper latch rod 11 passes through the upper part of the interior of the connecting seat two 9.
[0033] The interior of the connecting seat 2 9 and the connecting seat 3 10 is penetrated by a lower latch rod 12, and the connecting seat 2 9 and the connecting seat 3 10 are connected and fixed by the lower latch rod 12, thereby strengthening the fixation of the central cylinder head 4 and the second cylinder head 7. The lower latch rod 12 passes through the bottom of the interior of the connecting seat 2 9. By arranging latch rods on the upper and lower sides, the three cylinder heads remain stable when connected and will not be affected by external forces and cause up and down shaking.
[0034] Both ends of the upper latch rod 11 and the lower latch rod 12 are threadedly connected with hexagonal bolts 13. The hexagonal bolts 13 are screwed into both ends of the latch rod and tightened into place through threaded connection. The tightening process of the bolts will firmly fix the latch rod in the connecting seat to prevent the cylinder head from moving during subsequent use.
[0035] The implementation principle of a cylinder head structure in the embodiment of the present application is as follows: a person aligns the first clamping block 3 with the first positioning groove 2 on the first cylinder head 1, inserts it and ensures that the first cylinder head 1 and the center cylinder head 4 are preliminarily positioned through the first clamping block 3 and the first positioning groove 2, then aligns the second clamping block 6 with the second positioning groove 5 on the center cylinder head 4, inserts it and ensures that the center cylinder head 4 and the second cylinder head 7 are preliminarily positioned through the second clamping block 6 and the second positioning groove 5, completing the pre-installation of the three-part cylinder head, and then the person passes the upper latch rod 11 through the connecting seat 8 of the first cylinder head 1 and the center cylinder head 4, ensure that the pin rod is completely penetrated, screw in hexagonal bolts 13 at both ends of the upper pin rod 11, tighten the bolts in place through threaded connection, ensure the stable connection between the first cylinder head 1 and the middle cylinder head 4, pass the lower pin rod 12 through the connecting seat 2 9 of the middle cylinder head 4 and the connecting seat 3 10 of the second cylinder head 7, ensure that the pin rod is completely penetrated, screw in hexagonal bolts 13 at both ends of the lower pin rod 12, tighten the bolts in place through threaded connection, ensure the stable connection between the middle cylinder head 4 and the second cylinder head 7, and complete the final fixation of the entire cylinder head assembly.
