[0021] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figure 1 、 Figure 2As shown in the figure, the utility model provides a turning-milling composite lathe with the spindle box moving along the Y-axis, which includes a bed 1. A cross slide mechanism 2 is arranged on the front side of the top of the bed 1, and a gantry column mechanism 3 is arranged on the rear side of the top of the bed 1. The cross slide mechanism 2 includes a Z-axis motor 22 and two Z-axis slide bases 21. The two Z-axis slide bases 21 are respectively located on the left and right sides of the Z-axis motor 22. Both of the two Z-axis slide bases 21 are fixedly connected to the top of the bed 1. The output shaft of the Z-axis motor 22 is fixedly installed with a Z-axis lead screw 23. A Z-axis slider 25 is threadedly installed on the outer wall of the Z-axis lead screw 23. The top of the Z-axis slider 25 is fixedly installed with a saddle 26. T-shaped slides 24 are fixedly installed on the top of both of the two Z-axis slide bases 21. The saddle 26 is slidably connected to the two T-shaped slides 24 to improve the moving stability of the saddle 26. The top of the saddle 26 is fixedly installed with an X-axis drive box 27, and a slide plate 28 is arranged on the top of the X-axis drive box 27;

[0023] For each turning tool of the tool block 284 of the tool post, the Z-axis motor 22 is used to drive the Z-axis lead screw 23 to rotate, and in cooperation with the threaded connection between the Z-axis slider 25 and the Z-axis lead screw 23, the overall saddle 26 and the slide plate 28 on the top of the X-axis drive box 27 are driven to move along the Z-axis to complete the Z-axis adjustment turning of the workpiece to be machined.

[0024] As Figure 3 shown, an X-axis motor 271 is fixedly installed on the left side of the X-axis drive box 27. An X-axis chute 272 is opened on the top of the X-axis drive box 27. The output shaft of the X-axis motor 271 penetrates into the inner cavity of the X-axis chute 272 and is fixedly installed with an X-axis lead screw 273. The center of the bottom of the slide plate 28 is fixedly installed with an X-axis slider 281. The X-axis slider 281 is threadedly connected to the outer wall of the X-axis lead screw 273. The X-axis slider 281 is slidably connected to the X-axis chute 272 to maintain the stability of one end of the X-axis slider 281. An axial power tool block 282 is fixedly installed on the rear side of the top of the slide plate 28. A radial power tool block 283 is fixedly installed on the left side of the axial power tool block 282. A tool post tool block 284 is fixedly installed on the right side of the top of the slide plate 28;

[0025] By driving the X-axis lead screw 273 to rotate through the X-axis motor 271 and cooperating with the X-axis slider 281 at the bottom of the slide plate 28, the overall slide plate 28 can be driven to move along the X-axis while moving along the Z-axis to complete the X-axis adjustment turning of the workpiece to be machined.

[0026] As Figure 4 、 Figure 5As shown in the figure, the gantry main column mechanism 3 includes a gantry main column body 31. The gantry main column body 31 is fixedly connected to the top of the bed body 1. On the left side of the front end of the gantry main column body 31, a Y-axis chute 33 is provided. On the left side of the top of the gantry main column body 31, a Y-axis motor 32 is fixedly installed. The output shaft of the Y-axis motor 32 penetrates into the inner cavity of the Y-axis chute 33 and is fixedly installed with a Y-axis lead screw 34. A Y-axis slider 37 is threadedly installed on the outer wall of the Y-axis lead screw 34. The front end of the Y-axis slider 37 is on the same vertical line as the front end of the gantry main column body 31 and is fixedly installed with a spindle base plate 38. A spindle box 39 is fixedly installed on the front side of the spindle base plate 38. A Y-axis hydraulic brake 35 is fixedly installed on the top of the gantry main column body 31. The Y-axis hydraulic brake 35 is located on the right side of the Y-axis motor 32. A Y-axis rear pressure plate 36 is fixedly installed on the rear side of the gantry main column body 31 to ensure the smooth movement of the spindle box 39 along the Y-axis and eliminate the overturning tendency of the spindle box 39. A motor slot 391 is provided on the front side of the spindle box 39. A rotary motor 392 is fixedly installed inside the motor slot 391. The output shaft of the rotary motor 392 is fixedly installed with a positioning spindle 393. A workpiece to be machined is arranged at the front end of the positioning spindle 393.

[0027] During turning machining, the workpiece to be machined rotates with the positioning spindle 393. The positioning spindle 393, along with the spindle box 39 and the spindle base plate 38, drives the Y-axis lead screw 34 in the Y-axis chute 33 to rotate by using the Y-axis motor 32. With the threaded connection between the Y-axis slider 37 and it, it finally moves to the turning height position. The Y-axis hydraulic brake 35 is pressurized for braking, thereby locking the rotation of the output shaft of the Y-axis motor 32 and maintaining the accuracy of the Y-axis height.

[0028] Next, the working principle of the turning-milling compound machining lathe with the spindle box moving along the Y-axis will be specifically described.

[0029] As Figures 1 - 5As shown in the figure, during turning processing, the workpiece to be machined rotates with the positioning spindle 393. The positioning spindle 393, together with the spindle box 39 and the spindle base plate 38, rotates the Y-axis lead screw 34 in the Y-axis chute 33 by driving the Y-axis motor 32. In cooperation with the threaded connection between the Y-axis slider 37 and it, it finally moves to the turning height position. The Y-axis hydraulic brake 35 is pressurized for braking, thereby locking the rotation of the output shaft of the Y-axis motor 32 to maintain the accuracy of the Y-axis height. At the same time, each turning tool of the turret tool block 284 drives the Z-axis lead screw 23 to rotate by driving the Z-axis motor 22, and in cooperation with the threaded connection between the Z-axis slider 25 and the Z-axis lead screw 23, drives the overall saddle 26 and the slide plate 28 on the top of the X-axis drive box 27 to move in the Z-axis direction. By driving the X-axis lead screw 273 to rotate with the X-axis motor 271 and cooperating with the X-axis slider 281 at the bottom of the slide plate 28, the overall slide plate 28 can be driven to move in the X-axis direction while moving in the Z-axis direction to complete the turning processing of the workpiece to be machined. During radial milling processing, the Y-axis hydraulic brake 35 is depressurized. While the workpiece to be machined rotates with the positioning spindle 393, the spindle box 39 can continue to move in the Y-axis direction under the drive of the Y-axis motor 32. At the same time, each power tool of the radial power tool block 283 rotates and moves in the X and Z directions along with the slide plate 28 to complete the radial milling processing of the workpiece to be machined. Similarly, during axial milling processing, the Y-axis hydraulic brake 35 is depressurized. While the workpiece to be machined rotates with the positioning spindle 393, the spindle box 39 can continue to move in the Y-axis direction under the drive of the Y-axis motor 32. At the same time, each power tool of the axial power tool block 282 rotates and moves in the X and Z directions along with the slide plate 28 to complete the axial milling processing of the workpiece to be machined.

[0030] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
