As shown in fig. 1 to 5, the numerically controlled roller lathe of the present invention.
According to the automatic material grabbing equipment 3, a machining program can be completed on a numerical control roller lathe at one time, and single-piece or continuous multiple-piece machining can be completed through automatic material receiving.
The specific operation is as follows: the numerical control roller lathe puts the blank W from the tail part into the main spindle box by the automatic feeding device 1 and extends to the position of the limit sensor. A spacing sensor on the cutting tool rest controls a blank W distance signal to be transmitted to a control system, and the hydraulic chuck enables the hydraulic chuck to clamp the blank W through a hydraulic oil cylinder under the instruction of the control system.
And after the cutting tool rest finishes clamping the blank W, automatically cutting the blank W according to a control system program. And after the single-side cutting is finished, the cutting tool rest automatically cuts off according to the program of the control system. And (3) when the cutting is finished, a 2-4mm allowance is reserved, and the automatic material grabbing device 3 drives the material grabbing sliding plate to move forwards under the driving of a servo motor. When the material grabbing equipment is at the position of W1, the material grabbing hydraulic chuck is pulled by the hydraulic oil cylinder to clamp. The material grabbing chuck rotates to screw off the connecting part of the workpiece W1, and retreats to the cutting position, and secondary cutting is carried out on the processing surface of the workpiece W1.
And (5) after the material grabbing equipment performs secondary continuous cutting processing. The long cylinder on the automatic material receiving equipment 5 pushes the cylinder connecting plate to move forward, and the material receiving box is placed in front of the material grabbing chuck. The workpiece W1 on the hydraulic chuck loosening chuck moves back by the positioning cylinder to push the workpiece W1 into the receiving box. The short cylinder on the automatic material receiving equipment 5 moves backwards to pull the rotating arm to lift the material receiving box and place the material receiving box on the chute. The small material receiving cylinder pushes the material receiving hand forwards to be propped against the elastic spring, so that the material receiving hand is opened to place the workpiece W1 into the sliding chute, and the workpiece W1 flows out of the machining cutting area along with the sliding chute.
The size of the workpiece is cut off by a cutting tool rest after primary cutting according to a set processing program. The material grabbing chuck on the automatic material grabbing equipment 3 automatically receives the materials, and secondary processing is continuously carried out according to the program to finish the processing. The processed workpiece W1 is automatically unloaded into the material receiving box through material pushing equipment, and is transferred into the chute, and the workpiece W1 is placed into the chute through the protective cover of the processing area and is sent into the material box through the material outlet.
The automatic material grabbing device 3 adopts the servo motor to drive the screw rod assembly, drives the automatic material grabbing device 3 on the sliding plate to move back and forth, realizes material grabbing continuity and completes processing, thereby greatly improving the production efficiency and reducing the labor intensity of operators.
The automatic material receiving equipment 5 adopts a long cylinder to propel a cylinder connecting plate and a material receiving arm on a sliding block to move back and forth, so that a material receiving box is arranged at a workpiece, and the workpiece is smoothly placed in the material receiving box. The short cylinder drives the rotating arm to place the workpiece on the material sliding groove, and the small cylinder pushes the material receiving hand to open the material receiving box, so that the workpiece smoothly slides to the material outlet. The workpiece processing device provides guarantee for rapid and rapid transmission and auxiliary work of workpiece processing.
The workpiece processed by the full-automatic numerical control lathe is a roller bearing or a shaft workpiece.
The invention avoids the manual feeding, dumping, receiving and discharging links, ensures the uniform precision of workpieces, ensures the safety of workers, reduces the auxiliary time for processing the workpieces, reduces the labor force, reduces the production cost, increases the working efficiency, and has the advantages of compact structure, reasonable design, sensitivity, reliability and stable performance. Low labor intensity, high production efficiency, high processing precision, low production cost and the like. The automatic cutting equipment 2, the automatic material grabbing equipment 3, the automatic material pushing equipment 4 and the automatic material receiving equipment 5 are perfect combination of a numerical control lathe.
