The special-purpose rotating knife tower of turnning and milling numer centre
Technical field
The utility model relates to and a kind ofly is used for the numerically controlled lathe car, mills, the special-purpose rotating knife tower of turnning and milling numer centre of compound cutter tower and machining center machine rotary type tower, its cutter tower is divided into 4,6,8,12 four big specifications, belongs to the special-purpose rotating knife tower of turnning and milling numer centre and makes the field.
Background technology
In the background technology, cutter tower handle of a knife locking mode adopts the rear pull type locking mode at present, and the handle of a knife afterbody has a blind rivet, and oil pressure control knife striking cylinder to the effect of butterfly spring, makes mechanical three calvus work by knife striking cylinder, and gripper is caught the blind rivet post-tensioning, and handle of a knife is strained; General cutter tower need be joined VDI tool rest (Fig. 2-1), at car, mill, boring, bore, attack all can not exchange and all belong to special parts, not only the VDI tool rest costs an arm and a leg, handle of a knife is difficult for changing, and this handle of a knife loosening phenomenon of easy generation in process, in addition in the time need processing multi-hole position with one side, all need progressively unit processing, boring, tapping disposablely to finish, during different workpieces, can not install multi-shaft device additional, so waste man-hour, working (machining) efficiency is not good; On the spindle drive mode, general spindle drive all adopts the spline transmission in addition, and spline manufacturing process is loaded down with trivial details, the cost costliness.The easy beat in cutter tower orientation reaches the cutter tower and moves up and down (because the cutter tower only radially rotatablely moves), can not effectively reduce friction; Cutter tower rotational structure is to adopt the two-piece type clutch configuration in addition, and when the cutter tower need rotate, the cutter tower was just rotatable with calibration fluted disc disengagement raised bottom, so running accuracy is low, stability is not good.
Summary of the invention
One of purpose of design of the present utility model, handle of a knife adopts the nut check mode and utilizes V-type groove handle of a knife V-type groove, and the locking of nut clockwise direction is unclamped counterclockwise, to reach the purpose of being convenient to install, fix, take out V-type groove handle of a knife and changing multi-shaft device;
Two of purpose of design of the present utility model is installed multiaxis and is gone on the cutter tower;
Three of purpose of design of the present utility model, spindle drive adopt the concavo-convex connection kind of drive of a word;
Four of purpose of design of the present utility model, the rotation of cutter tower adopt high-accuracy worm gear, worm screw to cooperate the structure of triple plate clutch driven rotary;
Five of purpose of design of the present utility model, the rotation of cutter tower adopt the rotation of crossed roller bearing carrying cutter tower.
In order to realize one of above-mentioned purpose of design, cutter tower in the special nut locking device described in the utility model V-type groove handle of a knife 1-1. that all adopts international standards utilizes the advantage of V-type groove handle of a knife V-type groove 1-2, with special nut 1-5 V-type groove handle of a knife 1-1 is fastenedly connected with in-line homalocephalus tool shank cartridges 1-8. V-type groove handle of a knife U type groove 1-3 is aimed at locking special nut boss 1-6 V-type groove handle of a knife outer cone 1-4 and in-line homalocephalus tool shank cartridges inner cone 1-9 are coincide, behind the in-line homalocephalus tool shank cartridges of packing into the 1-8, special nut 1-5 is clockwise rotated and can lock; Otherwise, special nut 1-5 rotated counterclockwise to unclamp V-type groove handle of a knife 1-1, shortening V-type groove handle of a knife 1-1 greatly changes the time and replacing V-type groove handle of a knife 1-1 is provided facilitated method. and the benefit of doing like this is: general cutter tower handle of a knife locking mode adopts the rear pull type locking mode, the handle of a knife afterbody has a blind rivet, oil pressure control knife striking cylinder to the effect of butterfly spring, makes mechanical three calvus work by knife striking cylinder, gripper is caught the blind rivet post-tensioning, and handle of a knife is strained; General in addition cutter tower need be joined VDI tool rest 2-1; at car, mill, boring, bore, attack all can not exchange and all belong to special parts; and VDI tool rest 2-1 costs an arm and a leg. this cutter tower structure adopts the special nut locking mode; and adapted international standard V-type groove handle of a knife; can rapid changing knife reach and add required any standardization V-type groove handle of a knife cutter in man-hour; required with low cost; and having environmental protection efficacy concurrently. special nut also adopts pin 1-7 protection fastener, has guaranteed that loosening phenomenon does not take place in process V-type groove handle of a knife.
In order to realize two of above-mentioned purpose of design, the utlity model has the function that multi-shaft device 3-1 can be installed and change multi-shaft device.This function when needing the processing multi-hole position with one side, does not need progressively single hole processing at most of workpiece to be processed.After installing multi-shaft device additional, boring, tapping can disposablely be finished, and the activity duration shortens, and significantly improves working (machining) efficiency.During the processing different workpieces, replaceable multi-shaft device just can be finished in short a few minutes.Only note the correct orientation that multi-shaft device is installed.Multi-shaft device is installed on the multi-shaft device upper shell, and multi-shaft device upper shell 3-2 adopts the triple bond location, and its processing effect can keep high accuracy.
In order to realize three of above-mentioned purpose of design, along with science and technology development, require to improve existing transmission shaft structure and performance, in order to be applicable to the needs of the special-purpose rotating knife tower of turnning and milling numer centre condition of work, the utility model has designed the kind of drive of word connection power transmission shaft, i.e. word connection power transmission shaft kind of drive structure is made of in proper order guide holder 4-4, wear plate 4-6, in-line homalocephalus tool shank cartridges 1-8, spindle drive axle 4-2.Guide holder 4-4 is fastened on the base indirectly, and guide holder circle body normal plane is opened a circular hole 4-3, so that spindle drive axle 4-2 connects transmission, outer round surface has in-line guide groove 4-5, and the both ends of the surface distance is with normal plane circular hole center symmetry up and down.Wear plate 4-6 is installed in left surface and the right flank of guide holder in-line guide groove 4-5, effectively reduces friction, prolongs product service life.When in-line homalocephalus tool shank cartridges 1-8 was installed, in-line homalocephalus tool shank cartridges 1-8 afterbody became the in-line homalocephalus partly to pack in the guide holder in-line guide groove 4-5.When the cutter tower when rotated, drive in-line homalocephalus tool shank cartridges and do 360 deg circulation rotation with guide holder in-line guide groove.Behind the cutter tower rotation special angle, after in-line homalocephalus tool shank cartridges afterbody in-line homalocephalus changes over to and coincide in the spindle drive axle in-line groove 4-1, gradually drive spindle drive axle 4-2 rotation by servomotor, make the rotation of in-line homalocephalus tool shank cartridges, pack in in-line homalocephalus tool shank cartridges V-type groove handle of a knife and cutter can be processed part.The kind of drive that one word connects power transmission shaft improves the service behaviour that a word connects transmission mechanism, guarantee the reliability of its work, under the service load running, have that bearing capacity is big, structural rigidity good, shock resistance is strong, temperature rise is low, distortion is little, long service life, and processing is simple, low cost of manufacture, is convenient to the advantage of plant maintenance, maintenance and maintenance.
