Digital controlled lathe with multiple machining heads
Technical field
The invention belongs to field of mechanical technique, relate to a kind of numerically controlled lathe, particularly a kind of numerically controlled lathe that adopts a plurality of headstocks that a plurality of same workpiece are processed simultaneously.
Background technology
Along with the development of machinery manufacturing industry, engine lathe can not adapt to present production needs gradually.Numerically controlled lathe has solved above-mentioned shortcoming, and it to the automatic cyclic process of workpiece, can guarantee the homogeneity with a collection of workpiece size according to programme-control cutter stored in the computer, has improved the quality of product greatly.But existing numerically controlled lathe cost is higher, and it can only process a workpiece at every turn, and operating efficiency is not high.
Chinese patent 02231472.5 provides a kind of " double end numerically controlled lathe ", and it is to be provided with a geared head symmetrical with former geared head at the lathe guide rail other end.Drive cutter and move adding the planker of man-hour by the centre, thus processing work.After the workpiece completion of processing of left end, cutter can be processed the right-hand member workpiece, and cutter is processed in the process of right-hand member workpiece automatically, the workpiece of left end can be unloaded.Therefore, numerically controlled lathe is in the state of processing work always, and its working (machining) efficiency has raising slightly than centre numerically controlled lathe.But this double end numerically controlled lathe have only a cutter in use in work, so the raising of its working (machining) efficiency is not obvious, can't thoroughly solve the ineffective problem of numerically controlled lathe owing to adopt a cutter.
Summary of the invention
The objective of the invention is provides a kind of digital controlled lathe with multiple machining heads of novelty at the existing the problems referred to above of existing numerically controlled lathe, makes it have production efficiency height, low, the convenience operation of cost.
Purpose of the present invention can realize by following technical proposal: this digital controlled lathe with multiple machining heads, comprise a body, digital control system, headstock and motor, on the bed body saddle and upper slide rest are arranged, two main shafts are housed in the described headstock, it is characterized in that, on the described bed body saddle and a upper slide rest are arranged, upper slide rest is located on the saddle, two knife rests are arranged: lower slide and upper tool post on upper slide rest, upper tool post by several strut fixation on lower slide, the position of each knife rest is corresponding to the inner of each root main shaft, and the outer end of each root main shaft links by transmission mechanism and motor.
This digital controlled lathe with multiple machining heads is in the processing work process, and motor drives all main shafts by transmission mechanism and rotates together, is clamped in workpiece on the main shaft also along with rotation.At this moment, the cutter on each upper slide rest carries out machining to the workpiece that rotates simultaneously under the control of digital control system.
In above-mentioned digital controlled lathe with multiple machining heads, the outer end of described each root main shaft is joining by belt and machine shaft.Motor rotates each root main shaft by the transmission of belt together.
In above-mentioned digital controlled lathe with multiple machining heads, the outer end of described each root main shaft is joining by gear train and machine shaft.In this case, motor is the transmission by gear train, and each root main shaft is rotated together.
In above-mentioned digital controlled lathe with multiple machining heads, described two main shafts are arranged in parallel about being.
In above-mentioned digital controlled lathe with multiple machining heads, described two main shafts are to be arranged in parallel up and down.
Compared with prior art, this digital controlled lathe with multiple machining heads has the following advantages:
1, but therefore every of lathe equal workpiece of clamping of main shaft can be processed several workpiece simultaneously, and the operating efficiency of lathe improves several times, and the user also can save artificial and production site when reducing process equipment.
2, this digital controlled lathe with multiple machining heads is when producing, owing to be the same time several workpiece to be processed, so the quality of its product can be consistent; In addition, also capable of reducing energy consumption, have higher utility.

The specific embodiment
As shown in the figure, this digital controlled lathe with multiple machining heads comprises parts such as a body 1, digital control system 2, headstock 3, main shaft 4, saddle 5, upper slide rest 6 and motor 9.Main shaft 4 is loaded in the headstock 3, and digital control system 2 is controlled moving of saddles 5 and upper slide rest 6, thereby 11 pairs of workpiece of cutter are processed.In the present embodiment, two main shafts 4 are housed in the headstock 3, these two main shafts 4 are arranged in parallel up and down.Belt 12 is placed in main shaft 4 outer ends and motor 9 rotating shafts, also is with a belt 12 between two main shafts 4.During motor 9 work, two main shafts 4 are rotated together by belt 12 transmissions.
In the present embodiment, on the bed body 1 saddle 5 and a upper slide rest 6 are arranged, upper slide rest 6 is located on the saddle 5.Two knife rests are arranged on upper slide rest 6: lower slide 7 and upper tool post 8, upper tool post 8 is fixed on the lower slide 7 by several poles 10.The position of lower slide 7 and upper tool post 8 is corresponding with two above-mentioned main shafts 4.
On lower slide 7 and upper tool post 8, identical cutter 11 is housed.Cutter 11 is corresponding to the inner of main shaft 4, and these two cutters 11 are consistent with spacing between the pairing main shaft 4.
This digital controlled lathe with multiple machining heads is when work, and two main shafts 4 rotate simultaneously.Digital control system 2 is being controlled moving of saddle 5, upper slide rest 6, simultaneously identical workpiece is processed.
