Problems solved by technology

[0002] The existing processing of high-precision deep-hole parts mainly relies on the programming of CNC deep-hole drilling machines. The disadvantage is that the requirements for equipment are high, and the investment cost is high. Before processing, pilot holes need to be drilled, and the process is troublesome.
Moreover, for some parts that require high precision and large size, the existing CNC deep hole drilling machine still cannot meet the requirements in terms of accuracy.
[0003] Chinese patent document CN107350500A describes a method for processing deep holes, which adopts segmental processing and corrects the datum for processing, and assists in fine boring and honing processes, which can process deep holes, but this scheme is mainly aimed at deep holes with larger diameters. holes, which cannot meet the processing requirements of small diameter deep holes, for example, deep hole processing with a diameter of less than 20mm and a length of more than 500mm
Moreover, the process of this scheme is also relatively complicated, and it is easy to produce machining errors every time the tool is replaced.

Embodiment 1

[0031] Such as Figure 1~3 Among them, a deep hole processing device includes a bed 1, a drilling power head 2 is fixed on the bed 1, and a deep hole drill 4 is installed on the drilling power head 2. In the drilling power head 2, The drill base is connected with the motor through the transmission mechanism. The deep hole drill bit 4 is fixedly installed on the drill base. The workbench 5 is slidably installed on the bed 1 through the guide rail. They are also connected by a lead screw nut mechanism 11, the workpiece 6 is clamped on the workbench 5, and the feed of the workpiece is realized by the lead screw nut mechanism 11. By adopting the feeding method of the worktable 5, the transmission mechanism is reduced in the drilling power head 2, that is, the cumulative error caused by the transmission mechanism is reduced.

[0032] In a preferred solution, the workpiece 6 is rotatably clamped on the fixture 9 of the workbench 5 through a shaft, and the fixture 9 is also provided...

Embodiment 2

[0039] On the basis of Example 1, the preferred scheme is as figure 1 , 5 Among them, a laser-assisted calibration device is also provided. The structure is: a laser emitting device 10 is provided at one end of the bed, and a photoelectric collector 8 is provided at the other end. The laser emitting device 10 is used to emit a beam of collimated laser light through the deep hole. The drill bit 4 and the workpiece 6 are received by the photoelectric collector 8 .

[0040] In a preferred solution, the laser emitting device 10 is fixed on the drilling power head 2, and the laser emitting device 10 is used to emit a beam of laser beams along the axis of the deep hole drill 4, between the drilling power head 2 and the deep hole drill 4 There is a correction hole 12 on it;

[0041] The photoelectric collector 8 is fixed on the side of the fixture 9 away from the deep hole drill 4 , and an array of photosensitive elements is arranged on the photoelectric collector 8 . Preferably, ...
