Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1-2, the utility model relates to a kind of Digit Control Machine Tool with photoelectric encoder, comprise body 1, spindle drive motor 2, main spindle box 3, main shaft 4, swivelling tool-holder 5, X-axis drive motors 6, X-axis photoelectric encoder 7, X-axis leading screw 8, slide plate 9, Z axis leading screw 10, Z axis drive motors 11, Z axis photoelectric encoder 12 and tailstock 13, above described body 1, one end is provided with main spindle box 3, described main spindle box 3 is provided with main shaft 4, the side of described body 1 is provided with spindle drive motor 2, described spindle drive motor 2 is connected with main shaft 4 by driving shaft, above described body 1, the other end is connected with tailstock 13, described body 1 is connected with Z axis leading screw 10 by axle bed, described Z axis leading screw 10 one end is connected with Z axis drive motors 11 by driving shaft, described Z axis drive motors 11 is connected with Z axis photoelectric encoder 12, described body 1 is slidably connected by Z axis leading screw 10 and is provided with slide plate 9, above described slide plate 9, spiral is connected with swivelling tool-holder 5, described slide plate 9 is provided with X-axis leading screw 8, described X-axis leading screw 8 is connected with X-axis drive motors 6, described X-axis drive motors 6 is connected with X-axis photoelectric encoder 7, described body 1 is provided with numerical control box and servo drive, described body 1 is provided with illuminating lamp, described numerical control box is provided with display screen and control button, described numerical control box is also provided with alarm, described spindle drive motor 2, Z axis drive motors 11 and X-axis drive motors 6 are provided with decelerator, described decelerator, spindle drive motor 2, X-axis drive motors 6, X-axis photoelectric encoder 7, Z axis drive motors 11 is connected with numerical control box by holding wire respectively with Z axis photoelectric encoder 12.
