[0002] The horizontal boring machine is the most widely used type of boring machine. It is mainly used for hole processing with high boring accuracy. In addition to enlarging the cast or processed holes on parts, the horizontal boring machine can also mill planes, drill, process the outer circle of end faces and flanges, and cut threads.

[0003] The commonly used horizontal boring machines at present are double-sided single-station types. One or two parts can be clamped at the same time. The left and right power heads can complete the processing of pin holes at the same time.

The second driving mechanism 22 is used to drive the slide frame 23 to move. The second driving mechanism 22 includes a slide rail, a screw rod and a servo motor. The servo motor drives the screw rod to rotate, which can drive the slide frame 23 to slide. The driving direction of the second driving mechanism 22 is perpendicular to the driving direction of the first driving mechanism 3. The slide frame 23 is fixedly installed with The rotating motor 214 is installed under the sliding frame 23.

[0029] like Figure 6-Figure 7 As shown, a spray pipe 29 is connected to the power box 24, and the spray pipe 29 is connected to an external water pipe. The end of the spray pipe 29 faces the boring tool 28.

When the electric push rod 217 is extended, the slider 219 will first slide to one end of the slide groove 222 to the other end, thereby driving the baffle 2 15 moves to the depth of the part through hole, and the baffle 215 drives the water in the through hole to flow, thereby increasing the potential energy of the water and making it easier to flush out the debris; when the electric push rod 217 continues to extend, it drives the lifting block 220 to rise, thereby driving the baffle 215 to rise, and a large gap appears between the baffle 215 and the bottom of the part through hole. The water flow in the part through hole can drive the debris to flow out of the gap. With the continuous flushing of the water flow, the debris processed in the part through hole can be cleaned out in time.

[0030] During specific implementation: In this embodiment, the first driving mechanism 3 can drive the power mechanism 2 to move, so that the two power mechanisms 2 can move to the same side or both sides of the part, and the rotating motor 214 drives the power box to rotate 180°, and the second driving mechanism 22 can drive the power box 24 to move laterally to adjust the processing position of the part, so that the machine tool can process the same side or both sides of the part at the same time, thereby increasing the functionality of the machine tool; and through the setting of the baffle 215 and the electric push rod 217, the debris is driven to be cleaned out of the part through hole in time by water flow, solving the problem of difficulty in cleaning processing debris.
