Technical Field

[0001] This utility model relates to the technical field of marine diesel engines, and in particular to a cylinder head processing mechanism for medium and high speed marine diesel engines. Background Technology

[0002] Marine diesel engines are the "heart" of modern ships and the most important power equipment for all types of vessels. They are widely used in ship propulsion systems, ship power stations, and other systems. The cylinder head of a marine diesel engine is an important component of the engine, located at the top of the engine. It is bolted to the cylinder block to form a sealed space. Marine diesel engine cylinder heads are manufactured through a series of processing techniques, which require the use of many devices with processing mechanisms. Therefore, a special processing mechanism for medium- and high-speed marine diesel engine cylinder heads is needed.

[0003] However, most existing medium- and high-speed marine diesel engine cylinder head processing mechanisms cannot quickly and stably clamp the diesel engine cylinder head, which easily causes shaking during processing. Secondly, most processing devices cannot automatically perform rotation processing, resulting in low processing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a machining mechanism for medium- and high-speed marine diesel engine cylinder heads, in order to solve the problems mentioned in the background art. Most of the existing machining mechanisms for medium- and high-speed marine diesel engine cylinder heads cannot quickly and stably clamp the diesel engine cylinder head, and are prone to shaking during machining. In addition, most of the machining mechanisms cannot automatically perform rotational machining, resulting in low machining efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medium- and high-speed marine diesel engine cylinder head processing mechanism, including a support base, a clamping mechanism at one end of the support base, and a rotating mechanism at one end of the clamping mechanism;

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a medium- and high-speed marine diesel engine cylinder head processing mechanism, including a support base 1, a clamping mechanism 2 at one end of the support base 1, and a rotating mechanism 3 at one end of the clamping mechanism 2;

[0021] The clamping mechanism 2 includes a slide rail 201, a cylinder 202, a slider 203, a first connecting rod 204, a rotating plate 205, a second connecting rod 206, a moving plate 207, a limiting block 208, and a limiting groove 209. A slide rail 201 is fixedly mounted on one side surface of the support base 1, and a cylinder 202 is fixedly mounted on one side surface of the support base 1. One end of the cylinder 202 is connected to the slider 203, and a first connecting rod 204 is fixedly mounted on one side surface of the slider 203. One end of the first connecting rod 204 is connected to the rotating plate 205, and the other end of the rotating plate 205 is connected to the second connecting rod 206. A moving plate 207 is fixedly connected to one side surface of the second connecting rod 206. The mechanism is connected via the slide rail 201 and the cylinder 202. The arrangement of slider 203, first connecting rod 204, rotating plate 205, second connecting rod 206, and moving plate 207 allows for the following process: When machining a diesel engine cylinder head, cylinder 202 is activated, causing slider 203 to slide on slide rail 201. At this time, rotating plate 205 is driven to rotate, which in turn drives moving plate 207 to move. When moving plates 207 at both ends move towards the middle simultaneously, the diesel engine cylinder head can be stably clamped, preventing it from shaking during machining and increasing machining efficiency. Furthermore, when moving plate 207 moves, limiting block 208 slides in limiting groove 209, which limits the movement of moving plate 207.

[0022] Furthermore, a limiting block 208 is fixedly connected to one side surface of the movable plate 207, and a limiting groove 209 is opened on one side surface of the support base 1. With the setting of the movable plate 207, the movable plate 207 can stably clamp the diesel engine cylinder head when it moves.

[0023] Furthermore, the slider 203 and the slide rail 201 form a sliding structure. The two ends of the rotating plate 205 are connected to the first connecting rod 204 and the second connecting rod 206 respectively through bearings. With the arrangement of the slide rail 201 and the slider 203, when the slider 203 slides on the slide rail 201, the rotating plate 205 can drive the moving plate 207 to move.

[0024] Furthermore, the limiting block 208 forms a sliding structure with the support base 1 through the limiting groove 209. With the setting of the limiting block 208 and the limiting groove 209, the movement of the moving plate 207 can be limited when the limiting block 208 slides in the limiting groove 209.

[0025] Furthermore, the rotating mechanism 3 includes a connecting plate 301, a mounting plate 302, a motor 303, a rotating rod 304, a first gear 305, a connecting column 306, a second gear 307, and a clamping plate 308. The connecting plate 301 is fixedly mounted on one side surface of the moving plate 207, the mounting plate 302 is fixedly mounted on one side surface of the connecting plate 301, the motor 303 is fixedly mounted on one side surface of the mounting plate 302, one end of the motor 303 is connected to the rotating rod 304, one end of the rotating rod 304 is fixedly mounted with the first gear 305, one end of the connecting plate 301 is provided with a connecting column 306, and one end of the connecting column 306 is fixedly mounted with the second gear 305. 7. A clamping plate 308 is fixedly connected to one end of the connecting column 306. Through the arrangement of the connecting plate 301, mounting plate 302, motor 303, rotating rod 304, first gear 305, connecting column 306, second gear 307 and clamping plate 308, when machining the diesel engine cylinder head, the motor 303 is started. The motor 303 causes the rotating rod 304 to drive the first gear 305 to rotate. The second gear 307, which is meshed with the first gear 305, will drive the connecting column 306 to rotate. The clamping plate 308 fixedly connected to one end of the connecting column 306 can then drive the diesel engine cylinder head to rotate, realizing automatic rotation during the machining of the diesel engine cylinder head and improving the machining efficiency.

[0026] Furthermore, the rotating rod 304 and the first gear 305 form a rotating structure. The first gear 305 and the second gear 307 are meshed together. When the first gear 305 rotates, the second gear 307 will drive the connecting column 306 to rotate.

[0027] Furthermore, the connecting column 306 is connected to the connecting plate 301 via a bearing, and the clamping plate 308 forms a rotating structure with the connecting column 306 and the connecting plate 301. With the setting of the connecting column 306, when the connecting column 306 rotates, the clamping plate 308 will be driven to rotate.

[0028] Working principle: When machining the diesel engine cylinder head, cylinder 202 is started, which causes the slider 203 to slide on the slide rail 201. At this time, the rotating plate 205 is driven to rotate, which in turn drives the moving plate 207 to move. When the moving plates 207 at both ends move towards the middle at the same time, the diesel engine cylinder head can be stably clamped. Then, motor 303 is started, which causes the rotating rod 304 to drive the first gear 305 to rotate. The second gear 307, which is meshed with the first gear 305, will drive the connecting column 306 to rotate. The clamping plate 308, which is fixedly connected to one end of the connecting column 306, can then drive the diesel engine cylinder head to rotate.

[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
