Technical Field

[0001] The utility model relates to the technical field of exhaust manifold processing, and more specifically to a grinding mechanism for the exhaust manifold of a dual-fuel engine. Background Technique

[0002] A dual-fuel engine is an engine that can burn two types of fuels, mostly a diesel-natural gas dual-fuel engine. One of the components of the engine is the exhaust manifold, which is used to collect the exhaust gas from each cylinder and introduce it into the exhaust main pipe.

[0003] After retrieval, the Chinese patent document with the publication number CN210253494U discloses an exhaust manifold processing device. When performing processing operations such as grinding, cutting, and polishing on the exhaust manifold, the first fan in the dust suction body is driven to work, and the generated flying dust and other debris can be sucked into the dust suction body and discharged through the dust exhaust pipe to a position that does not affect the surrounding environment, thereby greatly reducing the harm to the surrounding environment. However, there are still the following defects. Since the exhaust manifold is mostly of a special-shaped structure, it is easy to occur that the clamping is unstable when using a clamping plate for clamping, resulting in defects in the flatness of the ground exhaust manifold, and thus causing air leakage at the connection. Content of the Utility Model

In addition, the forms of the various structures described in the following embodiments are merely examples, and the present utility model is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0024] Referring to Figures 1-5 , the present utility model provides a double-fuel engine exhaust manifold grinding mechanism, including a frame body 1. A power machine box 2 is provided on the outer wall of the top of the frame body 1. A grinding disc 3 is fixed to the output shaft of the power machine box 2 by bolts. A lifting frame 4 is provided on one side of the frame body 1, and the lifting frame 4 is connected to the frame body 1 through a lifting mechanism. Two clamping frames 13 are slidably connected to the inner wall of the bottom of the lifting frame 4. An adjusting mechanism for driving the two clamping frames 13 to move towards each other is provided on the outer wall of one side of the lifting frame 4. Avoidance openings 10 penetrating through the clamping frames 13 are provided on one side of each of the two clamping frames 13. Sliding openings are provided on the opposite sides of the two clamping frames 13, and sliding rods 11 are slidably connected in the sliding openings. A limiting mechanism for fixing the position of the sliding rod 11 is provided on the top of the clamping frame 13. One end of the sliding rod 11 is welded with a clamping plate 9. Rubber pads 8 are bonded to one side of each of the two clamping plates 9 to prevent the clamping plate 9 from directly contacting the exhaust manifold and protect the clamped exhaust manifold. During use, place the exhaust manifold on the lifting frame 4, adjust the position of the clamping frame 13 through the adjusting mechanism, so that the concentrator of the exhaust manifold passes through the avoidance opening 10 of the clamping frame 13, slide the sliding rod 11, change the position of the clamping plate 9, so that the exhaust manifold does not contact the avoidance opening 10, and use the limiting mechanism to fix the sliding rod 11, thereby completing the fixation of the exhaust manifold. Then use the lifting mechanism to adjust the position of the lifting frame 4 to make the exhaust manifold contact the grinding disc 3. Then start the power machine box 2, and the power machine box 2 drives the grinding disc 3 to rotate to grind the exhaust manifold, thereby completing the grinding of the exhaust manifold, strengthening the fixation during the grinding of the exhaust manifold, and improving the fixing stability of the device.

[0025] Among them, the lifting mechanism includes an electric telescopic rod 7. The electric telescopic rod 7 is fixed to the inner wall of one side of the frame body 1 by bolts, and the piston rod of the electric telescopic rod 7 passes through the frame body 1 and is fixed to the lifting frame 4. By starting the electric telescopic rod 7, the electric telescopic rod 7 can drive the lifting frame 4 to move up and down, thereby changing the position of the exhaust manifold, making the exhaust manifold contact the grinding disc 3, and then grinding it. A plurality of guide rods 6 are welded to the bottom of the lifting frame 4, and all the plurality of guide rods 6 pass through the frame body 1 and are slidably connected to the frame body 1. The guide rods 6 limit the moving direction of the lifting frame 4, avoid the lifting frame 4 from rotating during the lifting process, and at the same time make the lifting of the lifting frame 4 more stable.

[0026] Among them, the adjusting mechanism includes a bidirectional lead screw 12. The bidirectional lead screw 12 is rotatably connected between the inner walls on both sides of the lifting frame 4, and the bidirectional lead screw 12 is threadedly connected to the two clamping frames 13. At both ends of the bidirectional lead screw 12, a turning handle is fixed through the lifting frame 4 by bolts. By turning the turning handle, the turning handle drives the bidirectional lead screw 12 to rotate, thereby driving the two clamping frames 13 to move towards each other, and then clamping and fixing the exhaust manifold.

[0027] Among them, the limiting mechanism includes a sliding hole 15. The sliding hole 15 is opened at the top of the clamping frame 13, and the sliding hole 15 communicates with the sliding port. A positioning block 18 is slidably connected in the sliding hole 15. A plurality of uniformly distributed positioning grooves 16 are opened at the top of the sliding rod 11, and the positioning block 18 is clamped into the positioning groove 16. A sliding cover 14 is slidably connected to the top of the clamping frame 13, and the sliding cover 14 can contact the positioning block 18. By sliding the sliding rod 11, the sliding rod 11 drives the clamping plate 9 to move, thereby adjusting the positions of the clamping plate 9 and the clamping frame 13, and then avoiding the situation that the exhaust manifold is too wide to be clamped by the clamping frame 13. During the movement of the sliding rod 11, the positioning groove 16 at the top of the sliding rod 11 will squeeze the positioning block 18 to slide in the sliding hole 15, so that the positioning block 18 is located in another positioning groove 16. Then slide the sliding cover 14 to make the sliding cover 14 contact the positioning block 18 to limit the positioning block 18, thereby completing the fixation of the sliding rod 11. A baffle 17 is welded to one end of the sliding rod 11, which can prevent the sliding rod 11 from sliding out of the sliding port.

[0028] Among them, a protective plate 5 is welded to the top of the lifting frame 4. The protective plate 5 protects the bidirectional lead screw 12 to prevent the powder generated by grinding from falling onto the bidirectional lead screw 12. Two card slots 20 are opened at both ends of the protective plate 5. A cushion block 19 is inserted into the two card slots 20 at the same end. Another cushion block 19 can be inserted into the top of the cushion block 19, thereby adjusting the gap between the exhaust manifold and the protective plate 5, enabling the cushion block 19 to support the exhaust manifold and making the clamping of the exhaust manifold more stable.
