[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] Combined with the attached Figure 1 and the attached Figure 2 , a burr removal device for the inner wall of a large manifold of a marine diesel engine includes a base 1, a base 4 connected to the base 1, and a driving and processing component 3 connected to the base 4;

[0031] It further includes a pushing component 5. The pushing component 5 includes two pushing cylinders 53 connected to the upper and lower parts of the back surface of the base 4, a mounting disk 51 connected to the side surface of the base 4, an assembly disk 52 rotatably connected to the mounting disk 51, and a transmission shaft 54 passing through the mounting disk 51 and the base 4 and connected to the back surface of the assembly disk 52. The ends of the two pushing cylinders 53 are respectively fixedly connected to the mounting disk 51. A first transmission gear 55 is rotatably connected inside the back port of the mounting disk 51. A second transmission gear 56 is sleeved on one end of the transmission shaft 54. The first transmission gear 55 and the second transmission gear 56 are meshed with each other. A long shaft gear 57 is sleeved on the other end of the transmission shaft 54;

[0032] Combined with the attached Figure 2 and the attached Figure 3 As a preferred embodiment, a threaded joint 521 is connected to the outer wall surface of the assembly disk 52, and a plurality of circularly distributed assembly holes 522 are successively formed at the edge. A through groove 41 is provided in the middle of the base 4. The transmission shaft 54 is located in the through groove 41, and scales are provided on the transmission shaft 54;

[0033] Combined with the attached Figure 2 and Figure 3 As a preferred embodiment, a sleeve 58 is rotatably connected in the through groove 41. One end of the sleeve 58 is fixedly connected to the worm gear 33. A plurality of circularly distributed racks 59 are successively connected to the inner wall surface of the sleeve 58. Tooth grooves are formed between the plurality of racks 59. The long shaft gear 57 is located in the sleeve 58 and meshes with the tooth grooves formed by the racks 59.

[0034] When machining the diesel engine manifold, a machining tool, such as a grinding roller or a grinding disk, is screwed onto the assembly disk 52. Then, by starting the upper and lower two pushing cylinders 53, the two pushing cylinders 53 are used to synchronously push the mounting disk 51, the assembly disk 52 and the transmission shaft 54 to move together. At this time, the long shaft gear 57 at one end of the transmission shaft 54 slides in the sleeve 58, and the first transmission gear 55 and the second transmission gear 56 move together with the mounting disk 51 and the assembly disk 52. Then, the staff observes the scale exposed by the transmission shaft 54, and can accurately control the depth of the machining tool entering the manifold, so as to achieve accurate control, make the grinding roller or the grinding disk perform precise grinding, and improve the machining quality.

[0035] Combined with the attached Figure 1 and the attached Figure 2 As a preferred embodiment, the driving and machining component 3 includes a driving box 31 connected to one side surface of the base 4, a worm 32 rotatably connected inside the driving box 31, a worm gear 33, and a driving motor 34 connected to the driving box 31. The main shaft of the driving motor 34 is butted against the worm 32, and the worm 32 and the worm gear 33 are meshed and connected.

[0036] During use, by starting the drive motor 34, the drive motor 34 drives the worm 32, the worm gear 33 and the sleeve 58 to rotate. Since the rack 59 inside the sleeve 58 meshes with the long shaft gear 57, when the worm gear 33 rotates, the sleeve 58 together with the internal long shaft gear 57, the transmission gear II 56, the assembly disc 52 and the grinding roller or grinding disc rotate together, so as to achieve power synchronization and improve the processing efficiency without affecting the function of the pushing assembly 5.

[0037] Combined with the attached Figure 2 As a preferred embodiment, the base 4 is symmetrically provided with two limiting grooves 42 on one side of the mounting disc 51. The side surface of the mounting disc 51 is fixedly connected with limiting rods 43. Each limiting rod 43 is respectively inserted into each limiting groove 42. Each pushing cylinder 53 is respectively fixedly connected with each limiting rod 43. When the pushing cylinder 53 pushes, the two limiting rods 43 slide in the limiting grooves 42, playing a certain limiting role and improving the stability.

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, combined with the attached Figure 1 : The device further includes a sliding and fixing assembly 2. The sliding and fixing assembly 2 includes guide groove plates 23 horizontally connected to both sides of the base 4, a first clamping rod 21 and a second clamping rod 24 slidably connected in the two guide groove plates 23, and electric push rods 22 connected to the side surfaces of each guide groove plate 23 and respectively connected to the first clamping rod 21 and the second clamping rod 24. The surfaces of the two guide groove plates 23 are both provided with scales.

[0040] When fixing the diesel engine manifold, first start the telescopic rods of the two electric push rods 22 to contract, so that the first clamping rod 21 and the second clamping rod 24 are at appropriate distances respectively. Then start the telescopic rods of the two electric push rods 22 to extend, and press the first clamping rod 21 and the second clamping rod 24 against both ends of the manifold respectively. At this time, rubber pads can be arranged on the inner wall surfaces of the first clamping rod 21 and the second clamping rod 24 to improve the anti-slip and stable effect and prevent damage caused by excessive clamping force.

[0041] After processing one of the channel pipes of the diesel engine manifold, continue to repeat the above operation. At this time, observe the scales set on the guide groove plates 23. When the first clamping rod 21 and the second clamping rod 24 slide towards each other, the sliding distance can be accurately controlled, so that the diesel engine manifold can be accurately moved, and the next channel pipe of the manifold to be processed can be automatically positioned, which is convenient for processing and improves the processing quality and efficiency.

[0042] Combined with the attached Figure 4, as a preferred embodiment, a partition 12 is fixedly connected inside the base 1. The partition 12 divides the base 1 into a power supply area 13 and a counterweight area 14. A battery pack is connected inside the power supply area 13. The battery is used to supply power to the driving processing component 3, the pushing component 5 and the sliding fixing component. A counterweight block is connected inside the counterweight area 14 to improve the stability of the entire device during operation. A cover plate 11 is fixedly connected to the base 1 through fastening bolts.
