Problems solved by technology
[0002] CNC machine tools are widely used in mold processing and other fields, such as drilling. Due to the high processing accuracy of drilling, our company has improved the structure of vertical deep hole drilling machine tools, as recorded in the application publication number CN112873403A. A guide and positioning sleeve device is installed on the side of the drill bit device, and the extension rod is moved by the lifting mechanism to move the guide and positioning sleeve synchronously, and the extension rod is driven to rotate by a driving motor, so that the end of the guide sleeve is located under the drill bit according to the requirement, and the workpiece is adjusted in advance. Fix it, the drill bit is drilled through the hole of the guide sleeve, but it is found in the process of using the procedures in our company that the movement of the extension rod has the disadvantage of poor precision, which needs to be improved

The invention discloses a drilling machine tool which comprises a drilling device, a guiding and positioning device is arranged on one side of the drilling device, the guiding and positioning device comprises a positioning piece, a mounting base, a connecting rod, a sleeve, a driving mechanism, a first shifting mechanism, a second shifting mechanism and a guiding piece, and one or more guiding grooves for guiding vertical movement of the connecting rod are formed in the connecting rod. A guide groove is formed in the guide part, a sleeve is arranged in the guide groove, a protruding end is arranged on the sleeve in the radial direction and located in the corresponding guide groove, and the moving end of the second displacement mechanism is connected with the guide part so as to drive the end of the guide part to enter or be separated from the corresponding guide groove. And a guide groove is formed in the connecting rod (corresponding to the extension rod in the patent) and is matched with the guide piece to improve the moving precision of the connecting rod, so that better guiding and positioning effects are achieved, and the drilling precision is improved.
