A boring motor 74 is fixedly connected to the side wall of the plate 3, and the rotating shaft of the boring motor 74 is fixedly connected to the end of the gear rotating shaft of the reduction gear set 731. The other gear rotating shaft of the reduction gear set 731 passes through the moving plate 3 and is fixedly connected to the driving gear 732. A driven gear 741 is fixedly connected to the outer wall of the boring shaft 7, and the driving gear 732 is meshed with the driven gear 741. The reduction gear set 731 is composed of two or more groups of gears of different sizes and meshing with each other. Two groups are preferred here. In actual production, The configuration can be made according to the specific speed requirement, and the diameter of the driven gear 741 is larger than that of the driving gear 732; a plurality of water spray holes 721 are provided on the side wall of the boring tool group 72, and the water spray holes 721 are connected to the inner cavity of the boring shaft 7, and the boring shaft 7 is connected to the inner cavity of the positioning ring 71, and a guide part for conveying water to the boring shaft 7 is provided in the positioning ring 71; the guide part includes a guide blade 75, and a guide groove 751 is provided in the positioning ring 71, and the guide blade 75 is rotatably connected in the guide groove 751, and the reduction gear group The gear shaft of 731 passes through the guide groove 751 and is fixedly connected to the shaft of the guide blade 75.

The other end of the suction pipe 762 is connected to the inner cavity of the water storage box 4.

[0028] Through the arrangement of the above structure, when the boring motor 74 rotates, the guide blade 75 in the guide groove 751 will be driven to rotate rapidly, thereby generating a suction effect on the side close to the guide pipe 761. At this time, the water flow in the water storage box 4 will enter the guide groove 751 along the suction pipe 762, the guide box 76 and the guide pipe 761. After the water flows through the guide blade 75, it will be pushed into the inner cavity of the boring shaft 7 along the guide groove 751 and the positioning ring 71, and finally sprayed outward along the multiple groups of water spray holes 721, so that in the process of the boring tool group 72 rotating and boring, a ring can be generated on the inner wall of the hydraulic cylinder. The water jet has the effect of first cooling the boring tool set 72 and the inner wall of the hydraulic cylinder body, effectively reducing friction heat and improving the durability of the boring tool set 72. At the same time, it avoids thermal deformation of the inner wall of the hydraulic cylinder body, thereby ensuring machining accuracy. Secondly, the water flow can lubricate the machining surface, reduce the friction coefficient between the boring tool set 72 and the inner wall of the hydraulic cylinder body, make the boring process smoother, extend the service life of the boring tool set 72, and improve the boring quality of the hydraulic cylinder body. Moreover, the jetted water flow can block the debris generated by boring, avoid splashing of the debris, and improve the safety during boring. Subsequently, the mixture of water and debris will flow along the bottom of the hydraulic cylinder body to the water storage box 4, and finally pass through the residue suction groove 42 into the water storage box 4, thereby realizing the collection of water and debris. In conjunction with the setting of the residue filter plate 41, the filtered water will continue to be sucked into the guide groove 751, so that the water can be recycled, improving the energy-saving effect, and at the same time taking the debris away from the inner wall of the hydraulic cylinder body, reducing the damage and jamming of the boring tool group 72, and improving the smoothness and precision of the machined surface.

[0029] Reference Figure 3 , Figure 5 , Figure 7 and Figure 8 , wherein a filter plate 41 is fixedly connected inside the water storage box 4, and a residue suction groove 42 is provided on the top of the water storage box 4 near the limiting seat 2; the cleaning part includes two sets of water filter impellers 8 rotating in the same direction, and the two sets of water filter impellers 8 are rotatably connected to the two sides of the inner cavity of the water storage box 4, and the water filter impellers 8 are impellers made of filter mesh, which are used to filter debris in the water flow, and the water filter impellers 8 are provided with collecting grooves 81 inside, and the water-facing surface of the collecting groove 81 is rotatably connected with a water resistance plate 82, and the bottom of the water resistance plate 82 is connected to the collecting groove 81. A blocking spring 83 is fixedly connected between the inner walls of the collecting groove 81, and a linkage part for driving the water filter impeller 8 to rotate is arranged in the limit seat 2; the linkage part includes three sets of pulleys 84, and a linkage groove 841 is opened in the limit seat 2.

The three sets of pulleys 84 are respectively fixed on the two sets of water filter impellers 8 and the rotating shafts of the translation screw 6 located in the linkage groove 841, and the three sets of pulleys 84 are connected by belt transmission.

[0030] Through the arrangement of the above structure, while the translation screw 6 rotates, the transmission relationship formed between the three sets of pulleys 84 and the belts will cause the two sets of water filter impellers 8 to rotate in the same direction. When the water filter impeller 8 rotates, due to the effect of water flow resistance, the water-facing surface of the water filter impeller 8, that is, the water resistance plate 82, will move toward the side of the compression blocking spring 83, so that the water flow enters the collecting tank 81. At this time, the water flow will continuously pass through the water filter impeller 8, and the debris carried in the water flow will be trapped in the collecting tank 81. When the water filter impeller 8 stops rotating, the entrance of the collecting tank 81 will be re-blocked under the rebound action of the blocking spring 83, thereby effectively reducing the debris content in the water storage box 4, avoiding the situation where the debris causes blockage of the filter residue plate 41, and ensuring the water flow circulation efficiency.

[0031] Reference Figure 1-Figure 8 In the present invention, when in use, the hydraulic cylinder body is first placed on the limit seat 2, and then the lifting motor 53 is turned on to drive the lifting screw 51 to rotate, so that the clamping plate 5 moves downward along the lifting screw 51 and the lifting guide rod 52, and finally fits tightly with the top of the hydraulic cylinder body, so as to clamp and fix the hydraulic cylinder body, ensuring the stability of the hydraulic cylinder body during boring; then the boring motor 74 is turned on, and under the transmission action of the reduction gear group 731, the driving gear 732 and the driven gear 741, the boring shaft 7 drives the boring tool group 72 to rotate, and at the same time, the translation motor 62 is turned on to drive the translation screw 6 to rotate, so that the boring tool group 72 moves along the center of the inner cavity of the hydraulic cylinder, and as the boring tool group 72 continues to penetrate into the hydraulic cylinder body, the boring operation of the hydraulic cylinder body is completed, effectively improving the boring efficiency.

[0032] When the boring motor 74 rotates, the guide blade 75 in the guide groove 751 will be driven to rotate quickly, so as to generate suction on the side close to the guide pipe 761. At this time, the water flow in the water storage box 4 will enter the guide groove 751 along the suction pipe 762, the guide box 76 and the guide pipe 761. After the water flows through the guide blade 75, it will be pushed into the inner cavity of the boring shaft 7 along the guide groove 751 and the positioning ring 71, and finally sprayed outward along the multiple groups of water spray holes 721, so that in the process of the boring tool group 72 rotating and boring, a circular jet of water can be generated on the inner wall of the hydraulic cylinder. The function is to first cool down the boring tool set 72 and the inner wall of the hydraulic cylinder body, effectively reduce the friction heat, improve the durability of the boring tool set 72, and avoid thermal deformation of the inner wall of the hydraulic cylinder body, thereby ensuring the processing accuracy; secondly, the water flow can lubricate the processing surface, reduce the friction coefficient between the boring tool set 72 and the inner wall of the hydraulic cylinder body, make the boring process smoother, extend the service life of the boring tool set 72, and improve the boring quality of the hydraulic cylinder body; and the sprayed water flow can block the debris generated by boring, avoid the splashing of debris, and improve the safety during boring. Subsequently, the mixture of water and debris will flow along the bottom of the hydraulic cylinder body to the water storage box 4, and finally pass through the residue suction groove 42 into the water storage box 4, thereby realizing the collection of water and debris. In conjunction with the setting of the residue filter plate 41, the filtered water will continue to be sucked into the guide groove 751, so that the water can be recycled, improving the energy-saving effect, and at the same time taking the debris away from the inner wall of the hydraulic cylinder body, reducing the damage and jamming of the boring tool group 72, and improving the smoothness and precision of the machined surface.

[0033] When the translation screw 6 rotates, the transmission relationship formed between the three sets of pulleys 84 and the belts will cause the two sets of water filter impellers 8 to rotate in the same direction. When the water filter impeller 8 rotates, due to the effect of water flow resistance, the water-facing surface of the water filter impeller 8, that is, the water resistance plate 82, will move toward the side of the compression blocking spring 83, so that the water flow enters the collecting tank 81. At this time, the water flow will continuously pass through the water filter impeller 8, and the debris carried in the water flow will be trapped in the collecting tank 81. When the water filter impeller 8 stops rotating, the entrance of the collecting tank 81 will be re-blocked under the rebound action of the blocking spring 83, thereby effectively reducing the debris content in the water storage box 4, avoiding the situation where the debris causes blockage of the filter residue plate 41, and ensuring the water flow circulation efficiency. Finally, it is only necessary to remove the water filter impeller 8 regularly for cleaning.
