Abstract
The invention discloses a jacking knife, and relates to the field of machining equipment, in particular to the jacking knife. The jacking knife comprises knife bits and a bracket mounted on a slide plate in a machine tool, and is characterized in that a knife body is fixedly connected to the bracket, wherein the other end is connected with a pipe joint; the other end of the knife body is in threaded connection with a knife disc; the multiple knife bits are arranged on the knife disc, and are fastened on the knife disc through wedges; the knife disc and the knife bits are connected by screws; and the knife disc, the knife body and the bracket are all hollowed, and are communicated with each other. The jacking knife can realize multi-knife sectional cutting, is small in single cutting width, is low in knife loss, facilitates the chip removal and the heat dissipation, and improves the working efficiency.
Description
Technical field
The present invention relates to machining device field, be specifically related to trepanning tool.
Technical background
In technique, when draw ratio L/D >=5 in hole, be referred to as deep hole, hole is divided into again blind hole and through hole by its shape.The processing of deep hole, blind hole is a difficult point in mechanical processing technique, its difficulty be following some: (1) directly can not observe the working condition of cutter in process, indirectly can only judge wearing and tearing and the working condition of cutter.(2) heat in metal cutting is is not easily scattered and disappeared, and the design of cutter parameters is very difficult.(3) chip removal difficulty, owing to can not directly observe, is difficult to judge that whether hole internal chip evacuation is smooth and easy, scraps as the plug that is hampered then can cause the sharply wearing and tearing of cutter even to damage.(4) because the major part of cutter all works in the cavity of workpiece, the physical dimension of cutter is restricted, and cutter must keep enough intensity and rigidity, the global design of cutter is very difficult, and common way adds man-hour, and cutter consumption is large, efficiency is low, and cost is high.
Summary of the invention
In order to solve the problem, the invention provides one and can realize multitool segmentation cutting, single cutting width is few, and cutter losing quantity is little, and is conducive to the discharge of chip and the trepanning tool of heat radiation.
Trepanning tool of the present invention, comprise cutter head and be arranged on the bearing on lathe middle slide plate, it is characterized in that, described bearing is fixedly connected with a cutter hub, the other end is connected with a pipe joint, the described cutter hub other end has been threaded a cutterhead, described cutterhead is provided with several cutter heads, cutter head is fastened on cutterhead by wedge, and cutterhead and cutter head adopt screw to be connected, described cutterhead, cutter hub, bearing are hollow, and are interconnected.
Preferably, cutterhead inside and outside is provided with guide pad, and cutterhead is also provided with some chip areas.
Preferably, on cutterhead, the sword face of some cutter heads is stretched out size and is differed 0.3mm successively, and width increases 0.3mm successively.
The present invention can realize multitool segmentation and cut, and single cutting width is few, and cutter losing quantity is little, and is conducive to discharge and the heat radiation of chip, improves production efficiency.

Detailed description of the invention
Trepanning tool of the present invention, the bearing 6 comprising cutter head 1 and be arranged on lathe middle slide plate, described bearing 6 is fixedly connected with a cutter hub 5, the other end is connected with a pipe joint 7, pipe joint 7 is for passing into cooling fluid, described cutter 5 other end has been threaded a cutterhead 4, described cutterhead 4 is provided with several cutter heads 1, cutter head 1 is fastened on cutterhead 4 by wedge 2, and cutterhead 4 adopts screw to be connected with cutter head 1, described cutterhead 4, cutter hub 5, bearing 6 are hollow, and are interconnected, and are convenient to the outflow of cutting and cooling fluid.Cutterhead 4 inside and outside is provided with guide pad 3, cutterhead 4 is also provided with some chip areas 8.On cutterhead 4, the sword face of some cutter heads 1 is stretched out size and is differed 0.3mm successively, and width increases 0.3mm successively.
Cutterhead 4 clamps cutter head 1, and by thread connection on cutter hub 5, its outside studs with guide pad 3, and material is YG6, replaceable after wearing and tearing; The inner guide pad 3 YG6 being also housed and making, with the supporting material heart, prevents it sagging; Cutterhead 4 is designed with chip area 8, material selection 40Cr, heat treatment hardness 35HRC.Cutter hub 5 selects 45 steel.Cutter head 1 selects carbide alloy, adopts segmentation to cut and is beneficial to a point bits chip removal; The general not slope of width of chip exceedes chip space 1/3, is beneficial to chip removal.Adopt multitool segmentation to cut, cutter head 1 sword face is stretched out size and is differed 0.3mm successively, and cutting face becomes stairstepping.Its erection sequence to be noted when cutter head 1 is installed.As long as the amount of feeding is less than 0.3mm and just reliably can divides bits during cutting.Decreasing cutting width by giving multitool segmentation cutting, alleviating the cutting load of blade, also improving the machining condition of cutlery.
When trepanning tool is installed, workpiece first processes pilot hole, to ensure the axiality of workpiece and cutterhead 4, should note the fiting property in cutter and hole, to avoid vibration.First open cool motors during use, when cannelure fills cutting fluid, open dynamic main shaft and drive workpiece to rotate, cutter then just can be driven to cut.During parking, first feed-disabling motion must stop main axis again, finally just can close cooling device, in jacking process, when parking starts, by this procedure operation, otherwise must can cause serious consequence.In use procedure, must note color and the Vibration Condition of observing chip at any time, note abnormalities, necessary This vehicle stops frequently inspection, cuts after fixing a breakdown again.
