Description

Technical Field

[0001] This utility model relates to the technical field of printing roller processing equipment, specifically to a dual-station, dual-turret lathe. 。 Background Technology

[0002] Printing rollers are a type of printing mold. Currently, the lathes used for processing printing rollers are all single-station, single-turret lathes. When processing printing rollers, at least two loading and unloading operations are required, which is complex and labor-intensive for operators. In addition, the coaxiality difference caused by repeated loading and unloading leads to a decrease in the precision of the processed printing rollers, resulting in a high scrap rate. Existing single-station, single-turret lathes have low processing efficiency, occupy a large space, have high labor costs, and are complex to operate. Utility Model Content

[0003] This invention provides a dual-station, dual-turret lathe to solve the problems of low processing efficiency, large space occupation, and complex operation of existing single-station, single-turret lathes.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A dual-station, dual-turret lathe includes a bed, a spindle, a tailstock, turret A, and turret B. Several guide rails are mounted on the bed. The spindle and tailstock are connected to the guide rails on the bed via sliders. Centers are provided on the spindle and tailstock respectively. A spindle motor is mounted on the spindle. A C-axis motor drives a C-axis forward and reverse leadscrew to rotate. The C-axis forward and reverse leadscrews simultaneously move the spindle and tailstock along the guide rails towards the center or both ends. The left and right turrets are respectively mounted on the Z1 and Z2 intermediate support plates. The Z1 axis motor drives the Z1 axis leadscrew to rotate, causing the Z1 intermediate support plate to move left and right. The Z2 axis motor drives the Z2 axis leadscrew to rotate, causing the Z2 intermediate support plate to move left and right. An X1 axis guide rail is provided on the Z1 intermediate support plate, and the X1 axis motor drives turret A to move up and down via a leadscrew. An X2 axis guide rail is provided on the Z2 intermediate support plate, and the X2 axis motor drives turret B to move up and down via a leadscrew.

[0006] The Z1 axis lead screw and the Z2 axis lead screw are connected by a Z-axis support.

[0007] The working principle of this invention is as follows: The spindle and tailstock are rotated simultaneously towards the center / both ends via the forward and reverse C-axis lead screws, used to tighten or loosen the workpiece. The Z1 middle support plate is driven by the Z1 axis lead screw to move left or right, used for machining the length of the workpiece. The Z2 middle support plate is driven by the Z2 axis lead screw to move left or right, used for machining the length of the workpiece. Turret A moves downward or upward on the X1 axis guide rail, used for machining the diameter of the workpiece. Turret B moves downward or upward on the X2 axis guide rail, used for machining the diameter of the workpiece. The spindle and tailstock move simultaneously towards the center, tightening the workpiece. Turret A first machines the outer diameter of the workpiece, and turret B machines the rounded corner at the right end of the workpiece. After turret B finishes machining the rounded corner, it then machines the outer diameter. At this time, turrets A and B simultaneously machine towards the center of the workpiece. When turret A reaches the center of the workpiece length, it retracts to the left to machine the fillet. Turret B continues machining to the left until it exceeds the center of the length, ensuring that the machining areas of turret A and turret B overlap. After overlap, the machining is complete. The spindle and tailstock move outward simultaneously to remove the workpiece, completing the entire machining process.

[0008] This invention adopts a dual-station, dual-turret design, which saves one loading and unloading operation, reduces labor costs, and allows one machine to complete the processing of two machines, doubling the efficiency and reducing the labor intensity of operators. It also effectively solves the problem of coaxiality difference caused by repeated loading and unloading, improves the precision of the printed roller after processing, and reduces the scrap rate of the printed roller.

A spindle motor 20 is mounted on the spindle 2. A C-axis motor 6 drives a C-axis forward and reverse lead screw 4 to rotate. The C-axis forward and reverse lead screw 4 drives the spindle 2 and tailstock 3 to move simultaneously along the guide rails 5 towards the middle or both ends. Turret A14 and turret B17 are respectively mounted on the Z1 middle support plate 7 and the Z2 middle support plate. On the Z1 axis, the Z1 axis motor 9 drives the Z1 axis lead screw 8 to rotate, and the Z1 axis lead screw 8 drives the Z1 middle support plate 7 to move left and right; the Z2 axis motor 12 drives the Z2 axis lead screw 11 to rotate, and the Z2 axis lead screw 11 drives the Z2 middle support plate 10 to move left and right. The Z1 axis lead screw 8 and the Z2 axis lead screw 11 are connected by the Z-axis support seat 13. The Z1 middle support plate 7 is equipped with the X1 axis guide rail 16, and the X1 axis motor 15 drives the turret A14 to move up and down through the lead screw; the Z2 middle support plate 10 is equipped with the X2 axis guide rail 19, and the X2 axis motor 18 drives the turret B17 to move up and down through the lead screw.

[0013] The working principle of this invention is as follows: The spindle and tailstock are rotated simultaneously towards the center / both ends via the forward and reverse C-axis lead screws, used to tighten or loosen the workpiece. The Z1 middle support plate is driven by the Z1 axis lead screw to move left or right, used for machining the length of the workpiece. The Z2 middle support plate is driven by the Z2 axis lead screw to move left or right, used for machining the length of the workpiece. Turret A moves downward or upward on the X1 axis guide rail, used for machining the diameter of the workpiece. Turret B moves downward or upward on the X2 axis guide rail, used for machining the diameter of the workpiece. The spindle and tailstock move simultaneously towards the center, tightening the workpiece. Turret A first machines the outer diameter of the workpiece, and turret B machines the rounded corner at the right end of the workpiece. After turret B finishes machining the rounded corner, it then machines the outer diameter. At this time, turrets A and B simultaneously machine towards the center of the workpiece. When turret A reaches the center of the workpiece length, it retracts to the left to machine the fillet. Turret B continues machining to the left until it exceeds the center of the length, ensuring that the machining areas of turret A and turret B overlap. After overlap, the machining is complete. The spindle and tailstock move outward simultaneously to remove the workpiece, completing the entire machining process.
