Problems solved by technology
[0002] In the traditional vertical lathe, the tail of the main shaft faces down, the head faces up, and the workpiece is rotated vertically. The hole of the workpiece faces up, and the tool processes the hole from top to bottom. Chip removal and cleaning are very difficult, and chip accumulation in the hole is serious, especially for For blind hole parts, it is almost impossible to remove chips from the tool, which affects the normal processing of the machine tool, and even the accident of broken tool and waste parts occurs
The usual measures are to interrupt the continuous processing and increase the manual chip removal process with the help of special tools, resulting in problems such as the inability of a single machine to process continuously and the difficulty of continuous automatic operation of the assembly line.

Embodiment Construction
[0009] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0010] Such as figure 1 In the shown inverted turning electric spindle, the tail of the spindle 1 with a small diameter faces upwards, and the head with a large diameter and a short conical surface faces downwards and stands upside down. The lower and middle supports of the main shaft 1 are four pairs of main shaft bearings 29, arranged back-to-back to expand the support span, fixedly support the main shaft 1, and bear the radial and axial two-way force, the outer spacer 27 and the inner spacer 28 again increase the lower shaft , middle support span, utilize the length difference of outer spacer 27 and inner spacer 28 to pr...

The invention relates to an inverted-type turning electric spindle. A turning spindle is inverted, a workpiece is clamped in a suspended mode, a hole opening of the workpiece is downward, and the workpiece is machined through a hole-machining cutting tool below the workpiece; the cutting tool chip removal clearing effect is good, by additional cooperation of a large-flow cooling clearing system, the interference and influence effects of iron chips on machining are possible to be reduced to the minimum, the historical leftover problem that a traditional spindle erected machine tool cutting toolis poor in chip removal is solved, and a foundation is laid for long-time, continuous, automatic and reliable machining; a turning spindle inverted machine tool and a turning spindle erected machinetool are matched for use, and the turning clamping work procedure of the workpiece and a corresponding special carrying tool can be omitted; and a new machine tool is derived, a new research field isdeveloped for machine tool industries, and the certain scientific research value is achieved.
Description
technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an inverted turning electric spindle of a numerical control machine tool. Background technique [0002] In the traditional vertical lathe, the tail of the main shaft faces down, the head faces up, and the workpiece is rotated vertically. The hole of the workpiece faces up, and the tool processes the hole from top to bottom. It is very difficult to clean the chip, and the chip accumulation in the hole is serious, especially for For blind hole parts, it is almost impossible to remove chips from the tool, affecting the normal processing of the machine tool, and even accidents of broken tools and waste parts occur. The usual measures are to interrupt the continuous processing and increase the manual chip removal process with the help of special tools, resulting in problems such as the inability of a single machine to process continuously and the difficulty of continuous automa...
