[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0026] like Figures 1 to 3As shown, the radial feed small diameter deep hole device provided in the embodiment of the present invention includes a boring head body 1, an axial slider 3, a radial slider 4, a tool holder 5 and a tool 6. The axial slider 3 is installed on the boring head body 1, and the axial slider 3 can slide along the axial direction of the boring head body 1. The radial slider 4 is installed on the axial slider 3. The radial slider 4 can slide along the radial direction of the boring head body 1 under the drive of the axial slider 3. The tool 6 is installed on the axial slider 3 through the tool holder 5, and the boring head body 1 is installed on the pipe 9 to be processed through the mounting plate 8.

[0027] In the present invention, a guide groove is installed on the axial slider 3, and the guide groove is inclined from high to low from one end to the other end, that is, as the hole depth of the target hole increases, the guide groove is inclined from one end to the other end to gradually approach the target hole. Under the above structure, the position feed of the axial slider 3 is gradually adjusted, so that the radial slider 4 that slides with the guide groove is used to gradually push the tool 6 outward, so that the tool 6 is used to gradually process along the hole depth to form the target hole.

[0028] After inspection, it is found that the radial feed small diameter deep hole device provided by the present invention can be applied to small diameter and large aspect ratio deep hole parts, and can specifically meet the processing requirements for the required workpiece tapered holes, track line holes, and step holes.

To further illustrate the driving structure in the present invention, a conventional servo cylinder 2 is used as an example. The axial slider 3 is installed on the piston rod of the servo cylinder 2. The numerical control system 11 controls the position feed of the servo cylinder 22 through the proportional valve 10, and the position feedback signal of the servo cylinder 22 enters the numerical control system 11 to form a closed-loop control.
