Abstract

Disclosed is a pipe cutting machine capable of clamping workpieces automatically. The machine processes the inner holes and end surfaces of pipe workpieces clamped and fixed in an automatic centering fixture through move of a boring head. A four-connecting-rod mechanism feeding and blanking mechanical arm device is used for taking out a workpiece to be processed from a feeding frame and placed on a locating support, placing another workpiece to be processed which is on the locating support into the automatic centering fixture from the upper side of a fixture jaw, and simultaneously placing a processed workpiece in the automatic centering fixture into a blanking frame from the upper side of the fixture jaw; so that the automatic clamping process of the pipe workpieces is finished.

Description

Automatic pipe cutting machine

Technical field

The utility model relates to a kind of metal cutting machining tool, the especially automatic processing machine tool of the endoporus of metal tube subclass workpiece and end face.

Background technology

At present, turning and boring process are generally adopted in the processing of known metal tube subclass workpiece.In adopting the method for boring processing, clamping workpiece is moved by cutter rotation, boring head or workpiece workpiece is processed on fixing position.But, because boring processing has higher required precision to the clamping position of workpiece, generally adopt manual type will wait upon processing work install on the anchor clamps or with finished work by unloading on the anchor clamps.General boring mode pipe class machining tool owing to can not realize the automated exchanged cutter of workpiece, causes difficulty for the automation processing of pipe class workpiece, has limited the degree of pipe class workpiece automation processing.

Summary of the invention

In order to overcome the not high deficiency of existing pipe class machine tool for workpieces automaticity; The utility model provides a kind of automatic metal cutting pipe cutting machine; This lathe not only can be processed the endoporus and the end face of pipe class workpiece; But also can with finished work by unload automatically on the anchor clamps or with the workpiece to be processed automated exchanged cutter to anchor clamps, realized the automatic processing of pipe class workpiece.

The utility model solves the technical scheme that its technical problem adopted: moved by boring head the endoporus and the end face that are clamped in the pipe class workpiece in the fixed position are processed; On the lathe bed of lathe; The upper and lower material robot arm device of boring head, automatically centering fixture, quadric chain that can on bed ways, move is installed respectively; In forward and backward stock shelf and the blanking rack that processing work is installed respectively of lathe, the clamping of workpiece is placed into the workpiece to be processed on the stock shelf on the locating support, oriented workpiece to be processed on the locating support is placed in the automatically centering fixture, the workpiece that has machined in the automatically centering fixture is placed in the blanking rack simultaneously by 360 ° of rotations of upper and lower material robot arm device through the mechanical arm connecting rod in addition.When waiing upon after processing work puts on the stock shelf; The mechanical arm of upper and lower material robot arm device is placed into workpiece in the automatically centering fixture through 360 ° of rotations of mechanical arm connecting rod; After the automatically centering fixture jaw clamps piece-holder is fixed on the Working position, boring head is along treating that moving axially of workpiece process workpiece.After workpiece machines; The jaw of automatically centering fixture unclamps, and the mechanical arm of upper and lower material robot arm device is placed into the workpiece to be processed on the stock shelf on the workpiece locating support, oriented workpiece to be processed on the workpiece locating support is placed in the automatically centering fixture, the workpiece that has machined in the automatically centering fixture is placed in the blanking rack simultaneously through 360 ° of rotations of mechanical arm connecting rod once more.Reach the automated exchanged cutter of pipe class workpiece, the purpose of processing automatically.

The beneficial effect of the utility model is, can the automated exchanged cutter workpiece, and the material loading of workpiece, location, blanking are accomplished simultaneously, and be simple in structure, and automaticity is high.

1. bed pieces among the figure, 2. boring head, 3. feeding motor, 4. boring bar; 5. automatically centering fixture, 6. jaw, the 7. upper and lower material robot arm device of quadric chain, 8. finished work on the blanking rack; 9. the workpiece in the anchor clamps, 10. workpiece to be processed on the locating support is waitd upon processing work on 11. stock shelfs, 12. stock shelfs; 13. blanking rack, 14. mechanical arms, 15. mechanical arm connecting rods, 16. locating supports.

The specific embodiment

In Fig. 1; Many the flat respectively pendulum of stock shelf workpiece to be processed 11 are on stock shelf 12; When workpiece to be processed 10 on the locating support 16 after upper and lower material robot arm device 7 is placed in the automatically centering fixture 5 through quadric chain; Anchor clamps jaw 6 is to the radial direction clamping work pieces of workpiece, and after the workpiece in the anchor clamps 8 clamped, the boring bar 4 on the boring head 2 rotated; The axial direction of workpiece moves through the cutter that is installed on the boring bar workpiece is processed boring head in the driving lower edge of feeding motor 3; Machine the back boring head and retreat, the workpiece 9 in the anchor clamps that the upper and lower material robot arm device of quadric chain will machine is placed in the blanking rack 13, and finished work 8 rolls in the blanking rack along the slope automatically in the blanking rack; The upper and lower material robot arm device of quadric chain also is placed on the workpiece locating support, workpiece to be processed on the locating support 10 is placed in the automatically centering fixture waiing upon processing work 11 on the stock shelf simultaneously simultaneously, and other workpiece to be processed on the stock shelf tumbles along the slope automatically.

In embodiment illustrated in fig. 2; After workpiece machines; Anchor clamps jaw 6 unclamps; When mechanical arm connecting rod 15 clockwise directions of the upper and lower material robot arm device 7 of quadric chain turn to 180 ° of positions, workpiece to be processed 11 parallel picking-ups on the workpiece 9 in the anchor clamps that mechanical arm 14 will machine under the drive of mechanical arm connecting rod simultaneously, the workpiece to be processed 10 on the locating support 16, the stock shelf, the mechanical arm connecting rod is rotated further the workpiece that has machined and withdraws from anchor clamps by the top of anchor clamps jaw.

State embodiment illustrated in fig. 3 when turning to 90 ° of positions, that workpiece to be processed is parallel on the workpiece in the anchor clamps that mechanical arm will machine, the workpiece to be processed on the locating support, the stock shelf when holding up the extreme higher position for the mechanical arm connecting rod of the upper and lower material robot arm device of quadric chain.
