The numerically controlled lathe comprises a first main shaft and a second main shaft. A first through hole for feeding materials is arranged along the axial line of the first main shaft, a second through hole is arranged along the axial line of the second main shaft and sequentially provided with a telescopic ejector rob and an inductive switch, at least one part of the telescopic ejector rob extends out of an opening of one side of the second through hole towards the first main shaft, and a signal line of the inductive switch extends out of the second main shaft through an opening of the other side of the second main shaft far away the first main shaft along the second through hole and then is connected to a numerical control system of the numerically controlled lathe. When the workpiece is positioned opposite to the second main shaft, an end head of the workpiece extrudes the telescopic ejector rod to trigger the inductive switch. The second main shaft of the numerically controlled lathe disclosed by the invention is internally provided with a workpiece position induction device, relative to the second main shaft, a raw material is only precisely positioned, and the main shafts and a cutter can be opened to machine, thus the yield of products is improved and the generation of accidents is avoided.
Description
Technical field
The present invention relates to a kind of numerically controlled lathe, relate in particular to the numerically controlled lathe that a kind of second spindle end can be discerned the induction location of workpiece automatically.
Background technology
Numerically controlled lathe is the main product of machine industry, be to realize the modern key equipment of equipment manufacturing the present age, the quantity of China's high-performance numerically controlled lathe and kind a few days ago, still can not satisfy the demand of domestic market, high-tech industry particularly, bearing as China is made the special manufacturer, the efficient numerically controlled lathe of axletree bearing roller still is badly in need of very much, because the machining accuracy height of numerically controlled lathe is advanced in performance, the efficient height adds auxiliary equipment, feeder for example, material receiver can be realized fully-automatic production, and a people manages multiple computer desk, saves a large amount of labours.
Numerically controlled lathe generally comprises the lathe bed that is positioned on the base in the prior art, and base also is provided with the main shaft block, and the main spindle box of band main shaft is installed on the main shaft block, and an end of main shaft has chuck and is used for fixing workpiece.
Some numerically controlled lathes have adopted two main axle structures, and two main shafts of coaxial positioned opposite can utilize the two ends of the chuck fixed clamp workpiece at spindle nose position.When workpiece, often need promote raw material to second major axes orientation from first main shaft, the length of feeding is generally controlled by the stroke of feeding hydraulic cylinder in the prior art, but when raw material slightly tilts or is crooked, although the stroke of feeding hydraulic cylinder has reached predetermined value, with respect to second main shaft, raw material is accurately not in place, process if start two main shafts this moment, will inevitably produce defective work.
Summary of the invention
The invention provides the numerically controlled lathe of a kind of pair of main shaft, wherein whether an end of second main shaft can to respond to workpiece automatically in place.
A kind of numerically controlled lathe that can discern the induction location of workpiece automatically, comprise first main spindle box and second main spindle box, be respectively equipped with first main shaft and second main shaft in first main spindle box and second main spindle box, and first main shaft and the second main shaft coaxial arrangement, axis along first main shaft is provided with first through hole that is used for feeding, axis along second main shaft is provided with second through hole, flexible push rod and inductive switch are installed in second through hole successively, flexible push rod at least a portion is extended the opening of second through hole towards first main shaft, one side, the holding wire of inductive switch extends second main shaft along second through hole from the opening away from first main shaft, one side, insert the digital control system of numerically controlled lathe again, when workpiece was in place with respect to second main shaft, extruding flexible push rod in the termination of workpiece triggered inductive switch.
The inwall of described second through hole is provided with limited step, is provided with back-moving spring between flexible push rod and limited step, and flexible push rod is applied thrust towards first major axes orientation.
During feeding, raw material is gradually near the second main shaft end face (promptly locating end face), and begin to push flexible push rod, make in flexible push rod compression reseting spring retraction second through hole, when the raw material termination contacts the second main shaft end face, promptly flexible push rod also is in extreme position and triggers inductive switch, after the digital control system of numerically controlled lathe is received signal in place, begins raw material in place is processed.
Have location of workpiece induction installation in second main shaft of numerically controlled lathe of the present invention, with respect to second main shaft, raw material has only accurately in place, just can open main shaft and cutter is processed, and has improved product percent of pass, has avoided the generation of accident.

The specific embodiment
Referring to accompanying drawing, a kind of numerically controlled lathe that can discern the induction location of workpiece automatically of the present invention comprises first main spindle box and second main spindle box, is respectively equipped with first main shaft and second main shaft 1 of coaxial arrangement in first main spindle box and second main spindle box.
Because main the improvement is second main shaft, 1 part, so only shown second main shaft, 1 part among the figure.
Second main shaft 1 is provided with the chuck 2 that is used for holding workpiece 3 towards a side of first main shaft.
Axis along first main shaft is provided with first through hole that is used for feeding, axis along second main shaft 1 is provided with second through hole, flexible push rod 4 and inductive switch 6 are installed in second through hole successively, flexible push rod 4 at least a portion are extended the opening of second through hole towards first main shaft, one side, the holding wire 7 of inductive switch 6 extends second main shaft 1 along second through hole from the opening away from first main shaft, one side, inserts the digital control system of numerically controlled lathe again.
The inwall of second through hole is provided with limited step, is provided with back-moving spring 5 between flexible push rod 4 and limited step, and flexible push rod 4 is applied thrust towards first major axes orientation.
During feeding, workpiece 3 is gradually near second main shaft, 1 end face, and begin to push flexible push rod 4, flexible push rod 4 compression reseting springs 5, and in retraction second through hole, when workpiece 3 terminations contact the end face 8 of chuck 2, promptly flexible push rod 4 also is in extreme position and triggers inductive switch 6, when flexible push rod 4 is in extreme position and the distance between the inductive switch 6 be W, as long as promptly enter the induction zone (for example being generally 1mm) that triggers inductive switch 6, after the digital control system of numerically controlled lathe is received signal in place, begin workpiece in place 3 is processed.
When second main shaft 1 rotates, need to keep inductive switch 6 relative static with holding wire 7, can in second through hole, one sleeve pipe be installed by bearing, inductive switch 6 and holding wire 7 are fixed in the sleeve pipe, second main shaft, 1 afterbody also is with the tail cover by bearing, sleeve pipe and tail cover relative fixed and all cooperating by bearing with second main shaft 1, tail are overlapped direct or indirect again and circumferential the fixing of second main spindle box maintenance.
Have location of workpiece induction installation in second main shaft of numerically controlled lathe of the present invention, with respect to second main shaft, raw material has only accurately in place, just can open main shaft and cutter is processed, and has improved product percent of pass.
