Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and more specifically, to an engine exhaust manifold cutting device. Background Technology

[0002] An exhaust manifold is connected to the engine cylinder block, concentrating the exhaust gas from each cylinder and directing it into the main exhaust pipe. It is a branching pipe. The main requirements are to minimize exhaust resistance and avoid interference between cylinders. During the machining of the exhaust manifold, to ensure the flatness of the exhaust manifold ends, cutting is required. For example, patent application number CN202120752272.2 relates to the field of cutting technology. It discloses a manifold cutting device, including a base, a cutting mechanism, and a worktable. A fixed plate and a first cylinder are provided on the worktable. A movable plate is fixed to the output shaft of the first cylinder. Both the fixed plate and the movable plate have arc-shaped grooves, with the arc-shaped grooves on the fixed plate and the movable plate laterally opposite each other. It also includes a support mechanism that supports the fixed plate as the movable plate moves. This solution mainly addresses the problem that the current fixtures are not effective at positioning the manifold, causing displacement of the manifold during cutting. Different exhaust manifolds have different shapes, and the above-mentioned technical solutions can only position exhaust manifolds of the same specification. It is not easy to perform positioning work when machining exhaust manifolds of different specifications. Utility Model Content

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 , 2 As shown in Figure 3, an engine exhaust manifold cutting device includes a machining table 1. An electric guide rail 2 is mounted on the upper surface of the machining table 1. An electric guide block 4 is sleeved on the electric guide rail 2. An installation rod 5 is fixedly mounted on the upper surface of the electric guide block 4. A positioning plate 7 is fixedly mounted on the upper end surface of the installation rod 5. A first hydraulic cylinder 6 is fixedly mounted on one side surface of the positioning plate 7. A servo motor 10 is mounted on the output end of the first hydraulic cylinder 6. A cutting blade 11 is mounted on the output end of the servo motor 10.

[0020] like Figure 1 As shown, a support platform 8 is fixedly installed on the upper surface of the positioning plate 7, and a water pipe 9 is installed in the middle of the support platform 8. By connecting the water pipe 9 to the cutting fluid pipeline, the cutting fluid can move with the cutting blade 11 to perform spraying.

[0021] like Figure 2 , 3As shown in Figure 4, the system also includes a positioning component 3. The positioning component 3 includes a second hydraulic cylinder 301, a guide groove 308, and a side plate 311. The second hydraulic cylinder 301 is fixedly mounted on the upper surface of the processing table 1. The guide groove 308 is formed on the upper surface of the processing table 1. The side plate 311 is fixedly mounted on the upper surface of the processing table 1. A movable plate 302 is fixedly mounted on the output end of the second hydraulic cylinder 301. A mounting bracket 303 is fixedly mounted on one side surface of the side plate 311. A pressure plate 306 is slidably mounted between the inner walls of both sides of the mounting bracket 303. The inner walls are provided with sliding grooves 304. Slider blocks 307 are fixedly installed on both sides of the pressure plate 306. The sliders 307 are slidably installed inside the sliding grooves 304. A third hydraulic cylinder 305 is fixedly installed on the upper surface of the mounting bracket 303. The output end of the third hydraulic cylinder 305 is located on the upper surface of the pressure plate 306. A guide block 309 is slidably installed inside the guide groove 308. A support plate 312 is fixedly installed on the upper surface of the guide block 309. The support plate 312 is located on the lower surface of the mounting bracket 303. A reset spring is fixedly installed on the inner wall of the guide groove 308. Spring 310, one end of which is located on the side of guide block 309, adjusts the distance between moving plate 302 and support plate 312 to a suitable distance for exhaust manifold. Then, the exhaust manifold to be cut is placed between support plate 312 and moving plate 302. Support plate 312 will then move forward. When the exhaust manifold opening is moved between mounting bracket 303 and support plate 312, the return spring 310 will reset guide block 309, thereby driving support plate 312 to reset and positioning the exhaust manifold. Between the movable plate 302 and the support plate 312, the rear end of the exhaust manifold is tightly attached to the movable plate 302 to ensure the accuracy of the exhaust manifold position. At this time, the output end of the third hydraulic cylinder 305 is driven to drive the pressure plate 306 to move downward, and the upper end of the pressure plate 306 is placed on the upper surface of the exhaust manifold to fix the exhaust manifold. This device can limit and fix the exhaust manifold, ensuring the stability of the exhaust manifold during cutting. Moreover, this device can be adjusted at will and can be used to position exhaust manifolds of different specifications.

[0022] The working principle of this engine exhaust manifold cutting device:

[0023] In use, the second hydraulic cylinder 301 first drives the moving plate 302 forward, adjusting the distance between the moving plate 302 and the support plate 312 to a suitable distance for the exhaust manifold. The exhaust manifold to be cut is then placed between the support plate 312 and the moving plate 302. The support plate 312 then moves forward. When the exhaust manifold opening is moved between the mounting bracket 303 and the support plate 312, the return spring 310 resets the guide block 309, thus resetting the support plate 312 and positioning the exhaust manifold between the moving plate 302 and the support plate 312. The rear end of the exhaust manifold is tightly fitted onto the moving plate 302 to ensure accurate positioning. The third hydraulic cylinder 305 then drives the movement. The pressure plate 306 can be driven to move downwards, and the upper end of the pressure plate 306 is placed on the upper surface of the exhaust manifold to fix the exhaust manifold. This device can limit and fix the exhaust manifold, ensuring the stability of the exhaust manifold during cutting. Moreover, this device can be adjusted at will and can be positioned for exhaust manifolds of different specifications, improving the convenience of the device. At this time, the output end of the first hydraulic cylinder 6 is extended and retracted, which can drive the cutting blade 11 to move forward and fit the cutting blade 11 against one end surface of the exhaust manifold. The servo motor 10 drives the cutting blade 11 to rotate to perform cutting work at the exhaust manifold port. The electric guide block 4 moves in the middle of the electric guide rail 2, which can drive the cutting blade 11 to move and perform full grinding of the exhaust manifold port.
