The utility model can realize the index positioning in any angle of the main spindle through utilizing the peripheral shaft angle control function of a low-cost numerical control system, and has the characteristics of any angle indexing and high indexing precision.
Description
Technical field
The utility model belongs to the machining equipment technical field, particularly the numerically controlled lathe accessory.
Background technology
Has drilling, the numerically controlled lathe of milling function, high-end product---main shaft can drive feeding, because digital control system that need be high-grade and high-grade power knife rest are (at present, system and knife rest mainly rely on import) supporting, the lathe price is generally all more than 700,000 yuan, the CH7520 turning center of domestic certain machine tool plant for example, low-end product---main shaft is only done the interrupted division location, general using index dial (plate), the latch calibration, simple in structure, but can not realize arbitrarily angled calibration, limitation is big, for example Xi Anbei village XKNC-20FA is unit calibration location with 15 °.
Summary of the invention
The utility model purpose is the arbitrarily angled precision dividing apparatus of a kind of numerically controlled lathe C axle of design, utilizing economical CNC system periphery shaft angle degree control function to realize the arbitrarily angled calibration of main shaft location, and feasiblely have arbitrarily angled calibration, characteristics that indexing accuracy is high.
The arbitrarily angled precision dividing apparatus of numerically controlled lathe C axle, its be have with this device be installed on the main spindle box of lathe with main shaft on the angle block of right angle of dividing gear engagement, periphery axle servomotor is located the calibration that the dividing movement of motor passes to spindle index gear realization machine tool chief axis by tensioner cover and tensioner cover gland with coaxial being installed on the indexing means gear housing of hollow gear shaft; Cylinder be positioned at linear guides one side and by drive pressing plate drive indexing means property along the line guide rail move up and down realize indexing means with the spindle index gear meshing, separate; Gear is housed on hollow gear shaft.
At angle block of right angle one end wheel gear being housed meshes with gear and dividing gear respectively.
In the angle block of right angle bottom buffer spring and stroke collision block and stroke collision block are housed.
The economical CNC system periphery shaft angle degree control function of utilizing the utility model realizes the arbitrarily angled calibration of main shaft location, and feasiblely has arbitrarily angled calibration, characteristics that indexing accuracy is high.

The specific embodiment
As Figure 1-3, the arbitrarily angled precision dividing apparatus of numerically controlled lathe C axle, its be have with this device be installed on the main spindle box 1 of lathe with main shaft on the angle block of right angle 4 of dividing gear 13 engagements, periphery axle servomotor 12 is located the calibration that the dividing movement of motor passes to spindle index gear 13 realization machine tool chief axis by tensioner cover 11 and tensioner cover gland 8 with hollow gear shaft 9 coaxial being installed on the indexing means gear housing 10; Cylinder 14 is positioned at linear guides 3 one sides and drives indexing means property along the line guide rail 3 and move up and down the engagement that realizes indexing means and spindle index gear 13, separate by driving pressing plate 5; Gear 7 is housed on hollow gear shaft 9.At angle block of right angle 4 one ends wheel gear 2 being housed meshes with gear 7 and dividing gear 13 respectively.In the angle block of right angle bottom buffer spring 16 and stroke collision block 6 and stroke collision block 15 are housed.
This calibration device is installed in main spindle box top (installed surface guarantees that through grinding and scraping the installed surface knot touches rigidity) by angle block of right angle, with the engagement of dividing gear on the main shaft, separate and drive indexing means property along the line guide rail by the air cylinder driven pressing plate and move up and down, realize indexing means with the spindle index gear meshing, separate; Periphery axle servomotor is installed on the indexing means gear housing with hollow gear shaft is coaxial, by tensioner cover and tensioner cover gland the dividing movement of motor is passed to gear, realizes the calibration location of machine tool chief axis.Driving-chain adopts 1: 2 deceleration transmission, and gear 2 is a third wheel, and deceleration transmission had not only increased the moment of torsion of indexing means but also improved the precision of indexing means.Impact and overtighten for fear of when engagement cause gear to kill, this device designed buffer spring 9. with stroke collision block 1,15, guarantee the reliable and stable operation of indexing means.When main shaft enters the C Spindle Status, at first carry out the M19 main shaft and enter oriented approach, main axis rotation stops after finding zero-bit, carry out B0 instruction I/O Link axle simultaneously and get back to zero-bit, carry out the M58 gears engaged again, spindle index gear 13 teeth groove (top) and third wheel 2 tooth tops (groove) align, cylinder 14 pistons move down, two gears do not have the gap engagement, and the cylinder magnetic switch detects and puts in place, and it is directed to carry out the M18 cancellation then.Carry out and carry out M89 after Bxx location calibration is finished, main shaft is by mechanical grip, and rotary power head begins milling.Milling finishes and carries out the M90 main shaft and unclamp.
The process that the spindle index mode is converted to the spindle speed control mode is: at first stop the rotation of I/O Link axle, carry out on the M59 cylinder piston again and move, meshing gear separates, and carries out main shaft M03/M04 Sxxxx then, and main shaft is with regard to the admission velocity control mode.
Code control program (breviary) is as follows:
O1111
M19; The main shaft orientation
M50B0; The B axle is got back to zero-bit fast
