Description

Technical Field

[0001] The utility model relates to the field of mechanical processing equipment, in particular to a horizontal thin-wall long workpiece drilling machine tool. Background Art

[0002] During machining, for the hole-opening process on the side wall of a long workpiece, the existing technology usually adopts a horizontal fixing method, which places the long workpiece horizontally and fixes it at both ends. This has the following disadvantages:

[0003] 1. Supporting the workpiece at both ends requires two supporting structures, and manual calibration of the fixed position is required. The clamping efficiency is low and the clamping accuracy cannot be guaranteed.

[0004] 2. The drilling position relies on manual correction, and the hole positioning accuracy is not high.

[0005] 3. For the drilling process of thin-walled long workpieces, direct drilling can easily cause deformation of the workpiece, and an internal support structure needs to be added. Utility Model Content

[0006] In order to solve the problems of the prior art, the utility model provides a horizontal thin-walled long workpiece drilling machine tool, which adopts a vertical support device to support the workpiece for hole processing, combines the positioning device with the internal support structure to improve the clamping efficiency, and improves the positioning accuracy of the hole through high-precision turntable indexing positioning.

[0007] The utility model includes a base and a clamping device and a drilling device fixed on the base; the clamping device includes a turntable and an internal support clamp, wherein the turntable is fixed on the base, the internal support clamp is fixed on the turntable, the long cylindrical workpiece is sleeved on the outer edge of the internal support clamp, the internal support clamp is opened outward in the inner cavity of the long cylindrical workpiece and presses against the inner wall of the long cylindrical workpiece to fix the long cylindrical workpiece; a drilling mold is provided on the internal support clamp, and when the internal support clamp supports the long cylindrical workpiece, the drilled position is concentric with the drilling mold; the drilling device includes a main motor and a machining spindle, and the machining spindle is fixed to the base through a multi-degree-of-freedom displacement device.

[0008] As a further improvement, the multi-degree-of-freedom displacement device provides degrees of freedom in both horizontal and vertical directions, and includes a Z-axis servo motor, an X-axis servo motor, and a cross slide.

[0009] As a further improvement, the turntable is a high-precision turntable.

[0010] As a further improvement, a tool magazine is fixed on the base.

[0011] The beneficial effects of the utility model are:

[0012] 1. Compared with the existing horizontal installation, only one end is required to position the workpiece, and the positioning device and the internal support structure are combined to improve the clamping efficiency and accuracy.

[0013] 2. Through high-precision turntable indexing positioning, after machining one hole, the workpiece is rotated using the high-precision turntable so that the other hole position faces the machining spindle, thereby increasing the hole positioning accuracy.

[0014] 3. Add a tool magazine to facilitate the replacement of the tool head of the machining spindle and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
