Description

Technical Field

[0001] The present application relates to the field of machining equipment, and in particular to a high-precision high-low rail turret tail lift machine. Background Art

[0002] The development of CNC turning-milling centers, which rely on powered turrets and Y-axis technology, was a relatively late start in my country. With a limited number of manufacturers and a low market share, this has, to a certain extent, constrained the development of these centers among Chinese machine tool manufacturers. Existing CNC lathes utilize a specialized, high- and low-rail, stepped, slanted bed structure with angles of 30°, 45°, 60°, and 75°. Each machine has a specific angle and cannot be adjusted freely, failing to meet the increasingly complex and diverse processing needs of the CNC lathe industry.

By adopting the standard C-axis 0.001° control function on the output shaft, the processing or installation process of products of various shapes is guaranteed.

[0087] Work or process:

[0088] The workpiece is placed on the three-jaw chuck 16 and the three-jaw chuck 16 clamps the workpiece. The first motor 21 is started, and the output shaft of the first motor 21 drives the first screw rod 22 to rotate. The first screw rod 22 is threadedly connected to the first slider 23 and drives the first slider 23 to move horizontally along the extension direction of the first screw rod 22. The first slider 23 drives the thimble seat 19 to slide horizontally on one of the second slide rails 24. The thimble seat 19 drives the thimble rod 20 to move toward the side close to the three-jaw chuck 16 until the tip of the thimble seat 19 is pressed and contacted with the tail of the workpiece.

[0089] The second motor 25 is started, and the output shaft of the second motor 25 drives the second screw rod 26 to rotate. The second screw rod 26 is threadedly connected to the second slider 27 and drives the second slider 27 to move horizontally along the extension direction of the second screw rod 26. The second slider 27 drives the horizontal slide 18 and the tilting slide 28 to move horizontally on the other two second slide rails 24; the tilting slide 28 drives the mounting plate 33 to move horizontally synchronously, and the mounting plate 33 drives the cutter head disc 36 to move and approach the workpiece;

[0090] The tool changing motor 35 is started, and the output shaft of the tool changing motor 35 drives the cutter head disc 36 to rotate. The cutter head disc 36 rotates and rotates the cutting tool 37 used to cut the workpiece to the corresponding position; the tilting seat motor 29 is started, and the output shaft of the tilting seat motor 29 drives the tilting screw rod 30 to rotate. The tilting screw rod 30 is threadedly connected to the tilting slider 32, thereby driving the tilting slider 32 to move along the extension direction of the tilting screw rod 30. The tilting slider 32 drives the mounting plate 33 to move, and the mounting plate 33 drives the guide rail slider 31 and slides along the extension direction of the first slide rail 38. The mounting plate 33 drives the turret seat 34 to move. The turret seat 34 drives the cutting tool 37 to move toward the workpiece through the cutter head disc 36, and makes the cutting tool 37 contact with the workpiece and cuts the workpiece through the cutting tool 37.

[0091] When the cutting tool 37 needs to be replaced, the tilting seat motor 29 starts in reverse and drives the mounting plate 33 to move in reverse. The mounting plate 33 drives the cutting tool 37 to move to the side away from the cutting tool 37. The tool changing motor 35 starts and drives the cutter head disc 36 to rotate. The cutter head disc 36 rotates and drives the cutting tool 37 to rotate, and rotates the cutting tool 37 that needs to be replaced to the corresponding position. After that, the tilting seat motor 29 rotates forward again and drives the cutting tool 37 to approach the workpiece again for cutting, completing the quick tool changing work.

[0092] Since the tool head of each tool 37 is different after the tool is changed, the inclination angle between the tool 37 and the workpiece changes, the oil cylinder 39 is started, the piston rod of the oil cylinder 39 extends and pushes the articulated slider 40 from top to bottom, so that the inclination angle of the tilting slide 28 changes, causing the tilting slide 28 to drive the tool 37 to deflect, and the inclination angle between the tool head 37 and the workpiece is restored to the cutting state again; the inclination angle of the tilting slide 28 can be adjusted at will through the oil cylinder 39, avoiding the existing equipment having only a specific angle.

[0093] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
