A deep hole drilling machine tool with convenient conversion of drilling and milling functions

Abstract

A deep hole drilling machine tool with convenient drilling and milling conversion functions comprises a machine tool body, a working table installed on the machine tool body through a working table guide rail, a sliding platform lifting mechanism, a sliding platform driven by the sliding platform lifting mechanism to achieve Y-axis motion, a sliding plate fixed on the sliding platform and a drilling and milling exchange mechanism. The sliding plate is provided with a sliding plate guide rail, wherein a front guide box, a supporting frame and a main shaft box are sequentially arranged on the sliding plate guide rail from left to right in a sliding mode. The drilling and milling exchange mechanism comprises a drilling and milling exchange support, wherein the drilling and milling exchange support is provided with an arranging guide rail, the cross section of the arranging guide rail is the same as that of the sliding plate guide rail in shape and in size, and the arranging guide rail and the sliding plate guide rail can be in butt joint. Due to arrangement of the drilling and milling exchange mechanism, a Z-axis structural mode of an existing drilling and milling machine tool is broken through, free transfer of the front guide box and a supporting frame is achieved, the front guide box and the supporting frame do not need to be detached, influences on precision are avoided, and service life of the deep hole drilling machine tool is prolonged.

Description

technical field [0001] The invention relates to the field of drilling and milling machine tools, in particular to a machine tool capable of deep hole processing, gun drilling, single-tube drilling, jet suction drilling and milling. Background technique [0002] In the existing technology, it is very troublesome to realize the structure of drilling, milling exchange and one machine with multiple functions (gun drill, single-tube drill, jet suction drill), and the precision is not high, and they affect each other. Such as figure 1 As shown, in order to adapt to deep hole processing, the existing deep hole drilling and milling machine tool has a very long gun drill, which requires a front guide box and several support frames. When performing deep hole drilling and milling interchange, the gun drill needs to be longer And thin can meet the needs of deep hole processing, and because of the large working torque during milling, shorter and thicker milling cutters are needed to mee...

AI Technical Summary

Problems solved by technology

Because the front guide box has a certain width, the spindle must be made very long, which affects the cutting efficiency and machine tool accuracy;

[0004] 2. The structure of the front guide box of the gun drill, single-tube drill, and ejector drill is different. In order to be interchangeable, the front guide box is made very complicated, but even this is not effective and affects the accuracy of each other;

[0005] 3. An additional milling attachment is added, but it is not widely used due to the trouble of clamping

[0006] To sum up, the existing deep hole drilling and milling machine tools all have technical deficiencies, such as unreasonable structure, troublesome operation, low precision, low efficiency, and only one can be the main one, and the other can not be used as a supplementary state. Progress, the same machine tool cannot function normally on gun drilling, single tube drilling, ejector drilling and milling
