Abstract
A deep hole double-cutter boring head. The boring machine is characterized in that a double-blade boring cutter seat is arranged below a boring head body, double blades fixed by screws are arranged on the double-blade boring cutter seat, 2 hard alloy guide blocks welded with hard alloy blades by screws are arranged on the outer upper surface of the boring head body, one hard alloy guide block and the double-blade boring cutter seat are on the same diameter in the circumferential direction, the included angle between the two guide blocks is 100 degrees, 3 bakelite guide blocks fixed by screw washers are uniformly distributed in the circumferential direction behind the hard alloy guide blocks, and a square horn hole A is formed in the lower portion of the left end of the boring head body. The deep-hole double-cutter boring head has the characteristics of compact structure, reasonability and novelty, the maximum advantage of the boring head is 3-4 times higher than that of the boring head adopting the traditional deep-hole machining mode, and the machining precision is stable and reliable.
Description
Technical field
The utility model relates to deep hole machining dedicated tool, especially the deep hole double-pole boring head in a kind of machine cut processing cutting field.
Background technology
At present, former deep hole machining if run into big processing capacity, needs heavy boring feed several times or heavy boring---half right boring two procedures is finished, and number of cutters is many, changes cutter and fairlead is time-consuming, effort and complex process, and operating efficiency is low.
The utility model content
In order to overcome the deficiency that existing deep hole processing cutter exists, the utility model provides a kind of novel deep hole double-pole boring head, this deep hole double-pole boring head, by the size of each branch of control cutter, reduce the manufacturing procedure of workpiece, in the one-pass stroke, thick, half essence and fine finishining to the workpiece internal orifice dimension, excise more allowance, reach the dimensional requirement in aperture rapidly, realize efficiently, characteristics efficiently.
The technical scheme that its technical problem that solves the utility model adopts is: deep hole double-pole boring head, it is that the below of boring head body has a double blade boring cutter seat, on the double blade boring cutter seat double blade that is screwed is arranged, there are 2 above the external circle of boring head and are screwed the carbide alloy guide pad that is welded with carbide chip, one of them hard closes guide pad and double blade boring cutter seat circumferencial direction on same diameter, angle is 100 ° between two guide pads, the back of carbide alloy guide pad, there are 3 bakelite guide pad circumferencial directions of fixing with the screw packing ring evenly to distribute the side of having, the left end bottom bellmouth orifice A of boring head body.
Deep hole double-pole boring head, the cutter front end is furnished with the machine clip variable-position blade, can select different cutting parameters for use according to the required precision after material, mechanical performance, allowance and the processing of different workpieces, selects different blades simultaneously for use.Can select the import coated chip for use, to improve cutting speed.
When workpiece to be machined is blind hole, can be by opening the square bellmouth orifice A on the boring head body, chip removal in smear metal and cooling fluid realized by boring bar in boring head.
On the circumference that the opposite of blade and cutting force distribute, be mounted with two groups of carbide alloy guide pads, the distribution of guide pad makes it effectively offset the radial cutting force in the process, with the stationarity that keeps process and the linearity in hole.
The afterbody of cutter is that the targeting part that fabroil is made is installed, the effect of bakelite guide pad is: 1. when boring cutter is just cut workpiece, carbide alloy guide pad and bakelite guide pad closely contact with fairlead in the cutter fairlead, for boring cutter provides correct guiding; 2. after the workpiece process finishing, boring head is followed boring bar backward during withdrawing, and carbide alloy guide pad and bakelite guide pad are bearing on the hole wall all the time, thereby avoided because of the contacting of the sagging cutter head that causes under the boring head deadweight effect and hole wall, making, machining hole can not be scratched.
The beneficial effects of the utility model are, novel deep hole double-pole boring head, this cutter have compact conformation, reasonable novel features, and its sharpest edges are than improving work efficiency 3-4 times with traditional deep hole machining mode, and machining accuracy is reliable and stable.
