Abstract
The utility model relates to an electric tailstock of a lathe. A transmission screw of a tailstock of a known engine lathe is added with a single shaft numerical control system and a synchronous belt transmission mechanism to drive and control the linear movement of a tailstock sleeve tube. Thus, a cutter arranged at the tailstock sleeve tube can realize a plurality of numerical control and manual functions such as automatic operation according to the program, step feed or exit, continuous feed or exit, manual operation, etc., and all the manual functions of the traditional energy lathe can be realized under the power off condition. The utility model causes that a hole drilling function, a hole expanding function, a hole reaming function, etc., of the engine lathe can be realized with the automatic control; thus, the efficiency is higher, and the working accuracy is better.
Description
The technical field that the utility model relates to Metal Cutting Machine Tool (lathe) design and makes.
Tailstock---as a vitals on the horizontal lathe, its major function be on horizontal lathe to workpiece bore, expand, fraising or thimble is installed in order to the long workpiece of supporting etc.At present, technique known is that this tailstock person that can only lean on the machine operation manually finishes boring, reaming, fraising, the centering processing tasks of waiting for bus, and its shortcoming has following several:
(1) brill, fraising poor dimensional precision, surface roughness is poor.Because the hand feed meeting causes interrupted cut, and feed speed is fast or slow, therefore, the diameter in hole and depth dimensions precision all are difficult to guarantee, and the also easy scaling loss of drill bit; During fraising, because interrupted cut is left a trace at surface to be machined, feed speed can not stably be controlled again, and therefore, surface roughness after the fraising and dimensional accuracy can only be controlled at 7 class precisions or lower.The hinge blind hole is then more difficult.
(2) when a certain workpiece of batch machining, be difficult to realize repetitive positioning accuracy.
(3) because feed speed instability and cutting parameter are difficult to control, therefore, centre drill or drill bit fracture easily when drill centers or small diameter bore, and workpiece is scrapped.
Labour intensity is big when (4) holing.
(5) production efficiency is low.
Also having a kind of method in technique known is the straight-line motion mechanism that lathe tailstock is transformed into hydraulic driven.These needs that are mainly used in the production in enormous quantities are reused under the situation of tailstock thimble holding workpieces.Under the situation that has positioning accuracy request, repetitive positioning accuracy requirement, feed motion requirement and cutting speed to need often to change, then often can not meet the demands.
The purpose of this utility model is the electronic tailstock of a kind of novel lathe of design, it can not only keep every function of traditional lathe tailstock, and can realize the operation of automatic follow procedure, stepping feeding or withdraw from, continuous feed or many kinds of motion modes such as withdraw from, realize the multiple function of use of lathe tailstock.
The purpose of this utility model is achieved in that at the leading screw position of traditional lathe tailstock and connects a mechanical transmission mechanism, one stepper motor (or servomotor) is installed on transmission mechanism, and by the working method of the axle control module control step motor (or servomotor) in single shaft CNC (numerical control) system or CNC machine tools (numerical control) system, when stepper motor (or servomotor) is pressed CNC (numerical control) system program command job, by mechanical transmission mechanism, rotatablely moving of stepper motor (or servomotor) will be become the rectilinear motion of tailstock and cutting tool.And realize the automation control of motion and the multiple function of use of lathe tailstock.
Owing to adopted such scheme, the cutting tool on the lathe tailstock just can be by the program command work of CNC (numerical control) system, realize automatic follow procedure operation, stepping feeding or withdraw from, continuous feed or withdraw from, manual many kinds of digital control processing functions such as operation.Changed the backward situation that labour intensity is big, productivity ratio is low, machining accuracy is low that manual operations is in the past produced.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an overall construction drawing of the present utility model.
1. pressing plates, 2. base plates, 3. slide plates, 4. adjusting screw(rod)s, 5. adjusting nuts, 6. alignment pins, 7. round nuts 8. are stopped and are close to bar 9. tailstock main body 10. thimbles, 11. sleeve 12. hold-down bolts, 13. set lever 14. clamp nuts, 15. leading screw 16. motors, 17. digital control systems and control box 18. feed screw nuts 19. bearings 20. deceleration box 21. main synchronous pulley 22. Timing Belts 23. bearing glands 24. fastening screw nuts 25. handwheels 26. expansion sleeves 27. screws 28. passive and synchronous belt wheels 29. tight handle 30. eccentric shafts of stopping among the figure
In the drawings, sleeve (11) can be made free rectilinear motion in the through hole of tailstock main body (9), sleeve (11) connects firmly mutually with feed screw nut (18) again, leading screw (15) connects firmly mutually with passive and synchronous belt wheel (28), deceleration box (20) connects firmly mutually with tailstock main body (9), and motor (16) connects firmly mutually with deceleration box (20), and main synchronous pulley (21) connects firmly mutually with motor (16),, the digital control system and the operation panel (17) that are fixed on the tailstock main body (9) are realized being electrically connected with motor (16).According to this scheme, when motor (16) rotates, by main synchronous pulley (21), the effect of the mechanical transmission mechanism of band (22), passive and synchronous belt wheel (28), leading screw (15), feed screw nut parts such as (28) composition synchronously, sleeve (11) is with regard to moving linearly, and the cutting tool that is installed on the sleeve (11) is just made corresponding rectilinear motion.When the machine operation person by operating numerical control system and operation panel (17), make motor (16) when rotating according to certain rules, cutting tool is moving linearly according to certain rules just also.
Under the out-of-work situation of motor (16),, still can realize every manual function of traditional engine lathe by the handwheel (25) that connects firmly mutually with leading screw (15).
The utility model is applicable to that all kinds of horizontal digital-control lathes are supporting, is applicable to that also all kinds of horizontal engine lathes are supporting, and can carry out renewal and reform to existing all kinds of old horizontal engine lathe tailstocks.
