Abstract

The utility model relates to a special locking nut of a combined cutter tower for lathing and milling on a numerical control lathe and a rotary cutter tower on a machining center machine. A cutter shank adopts a locking nut locking structure and utilizes a V-shaped groove of a V-shaped slotted cutter shank to realize the functions of facilitating mounting, fixing and taking out a V-shaped slotted cutter shank and replacing a multi-axis device by locking a locking nut clockwise or loosening the locking nut counterclockwise. The utility model has the advantages that the V-shaped slotted cutter shank has short replacement time, high speed and convenient replacement; the multi-axis device can be mounted; the functions of the multi-axis device can be replaced; and drilling and tapping can be finished in one step to shorten the operation time and greatly improve the machining efficiency.

Description

The special-purpose locking nut of rotating knife tower

Technical field

The utility model relates to and a kind ofly is used for the numerically controlled lathe car, mills, the special-purpose locking nut of rotating knife tower of compound cutter tower and machining center machine rotary type tower, belongs to the special-purpose locking nut of rotating knife tower 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

Purpose of design of the present utility model, handle of a knife adopts the locking nut locking mode and utilizes V-type groove handle of a knife V-type groove, and the locking of locking 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.

In order to realize above-mentioned purpose of design.Cutter tower in the locking nut locking device described in the utility model V-type groove handle of a knife (1-1) of all adopting international standards.Utilize the advantage of V-type groove handle of a knife V-type groove (1-2), V-type groove handle of a knife (1-1) and in-line homalocephalus tool shank cartridges (1-8) are fastenedly connected with locking nut (1-5).V-type groove handle of a knife U type groove (1-3) is aimed at locking nut boss (1-6) coincide V-type groove handle of a knife outer cone (1-4) and in-line homalocephalus tool shank cartridges inner cone (1-9), after the in-line homalocephalus tool shank cartridges (1-8) of packing into, locking nut (1-5) is clockwise rotated and can lock; Otherwise, locking nut (1-5) rotated counterclockwise can unclamp V-type groove handle of a knife (1-1), shorten V-type groove handle of a knife (1-1) the replacing time greatly and provide and change V-type groove handle of a knife (1-1) facilitated method.The benefit of doing like this is: general cutter tower handle of a knife locking mode adopts the rear pull type locking mode, and the handle of a knife afterbody has a blind rivet, oil pressure control knife striking cylinder, by knife striking cylinder to the effect of butterfly spring, make mechanical three calvus work, 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 (Fig. 2-1), and at car, mill, boring, bore, attack all can not exchange and all belong to special parts, and VDI tool rest (Fig. 2-1) costs an arm and a leg.This cutter tower structure adopts the locking nut locking mode, and adapted international standard V-type groove handle of a knife, can rapid changing knife reaches and adds required any standardization V-type groove handle of a knife cutter in man-hour, and is required with low cost, and has environmental protection efficacy concurrently.Locking 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.

Technical scheme: the special-purpose locking nut of rotating knife tower, it comprises the cutter tower, the V-shaped groove of V-type groove handle of a knife and V-type groove handle of a knife and in-line homalocephalus tool shank cartridges are fastenedly connected by locking nut in the locking device in the described cutter tower.

The utility model is compared with background technology, and the one, the handle of a knife replacing time is short, speed is fast and be convenient to replacing; The 2nd, the function that multi-shaft device and replacing multi-shaft device can be installed, its boring, tapping can disposablely be finished, and the activity duration shortens, and increases substantially working (machining) efficiency.
