Abstract
A large-sized and efficient deep hole machining boring head belongs to machining equipment for inner holes and deep holes. The boring head mainly comprises a boring head body, wherein the boring head body is provided with a boring rod joint; one side of the boring head body is provided with at least one boring hole sticker holder; the inside of the boring head body is also provided with a floating tool post and cooling and lubricating oil pipes; the cooling and lubricating oil pipes are respectively communicated with the boring hole sticker holder and the floating tool post; and the outside of the boring head body is also provided with a guide holder. The boring head body adopts a weld structure and is fixed with the guide holder; more than one boring hole sticker and a floating boring cutter block can be arranged on the boring head at the same time, thereby completing both rough machining and finish machining of an inner hole within one stroke; the center of the boring head is provided with a cooling lubricating fluid inlet, and lubricating fluid enters the boring head from the inside of the boring rod via a central cooling pipe of the boring head body and is sprayed to each boring cutter cutting edge through each cooling and lubricating oil pipe, thereby realizing complete cooling and lubrication of the boring cutter cutting edges and high-speed and efficient deep hole boring.
Description
Technical field
The utility model relates to a kind of deep hole drilling and boring machine boring head, relates in particular to a kind of boring head of large hydraulic headstock gear cylinder inner bore deep hole machining.
Background technology
Existing deep hole machining mostly is overall structure greatly with boring head, owing to will control boring head weight, boring head length is shorter, and the supporting position is also shorter, adds lacking of cutter dress in man-hour, working (machining) efficiency is lower, because guiding length is shorter, the linearity of machining hole is relatively poor, can only process the aperture in the certain size scope, general regulated quantity is in 30～50mm scope, and the hole of scale out need make new boring head.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of cutter that installs additional many, working (machining) efficiency height, the large-scale high-effective deep hole processing boring head that the linearity of machining hole is good.
The purpose of this utility model is achieved in that a kind of large-scale high-effective deep hole processing boring head, comprise boring head body 5, boring head body 5 is provided with boring bar joint 6, boring head body 5 one sides are provided with at least one bore hole sharp knife seat 1, also be provided with the tool rest 3 that floats in the boring head body 5, be provided with cooling, lubricating oil pipe 2 in the boring head body 5, cooling, lubricating oil pipe 2 are switched to bore hole sharp knife seat 1 and unsteady tool rest 3 places respectively; Boring head body 5 outsides also are provided with guide holder 4.
Large-scale high-effective deep hole processing boring head provided by the utility model, boring head adopts Welding Structure, be set with guide holder on it, an above bore hole sharp knife and can be installed simultaneously the floating boring tool piece on the boring head, one stroke can be finished thick, the fine finishining of endoporus.The boring head center is provided with a cooling-lubricant inlet, cooling fluid enters from boring bar inside through boring head body center cooling tube, spray to each boring cutter cutting edge by each cooling, lubricating oil pipe on the boring head body, realized the abundant cooling and lubricating of boring head cutting edge, can realize that high-speed and high-efficiency ground carries out deep hole boring.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done a step explanation.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The utility model adopts following structure: a kind of large-scale high-effective deep hole processing boring head, comprise boring head body 5, boring head body 5 is provided with boring bar joint 6, boring head body 5 one sides are provided with at least one bore hole sharp knife seat 1, also be provided with the tool rest 3 that floats in the boring head body 5, be provided with cooling, lubricating oil pipe 2 in the boring head body 5, cooling, lubricating oil pipe 2 are switched to bore hole sharp knife seat 1 and unsteady tool rest 3 places respectively; Boring head body 5 outsides also are provided with guide holder 4.
Referring to Fig. 1 and Fig. 2, bore hole sharp knife seat 1 of the present utility model is welded on the boring head body 5, inside is provided with cooling, lubricating pipe, by sharp knife cooling, lubricating oil pipe 2 three single-blade boring cutter pieces to installing respectively, be that the bore hole sharp knife cools off, lubricates, can realize the headstock gear cylinder inner bore is carried out roughing; The floating tool rest 3 of bore hole can be installed adjustable twolip boring cutter piece, adjustable twolip boring cutter piece floats in the floating tool rest 3 of bore hole, can in rectangular channel, slide, can borrow the cutting force that acts on the symmetrical blade to come its cutting position of autobalance during boring, therefore the harmful effect that beating of the manufacturing of boring cutter piece, alignment error and boring bar etc. causes can be compensated for, thereby higher aperture precision and thinner surface roughness can be obtained.Can realize the headstock gear cylinder inner bore is carried out semifinishing and fine finishining; Adjustable twolip boring cutter piece relies on the floating cutter cooling, the lubricating oil pipe that are welded in the floating tool rest both sides of bore hole to cool off, lubricate.Boring head body 5 is welded to form by five gripper shoes and middle steel pipe, is the basic element of character of boring head, and it forms a whole other each parts; The effect of boring bar joint 6 is by square thread boring bar on whole boring head and the boring machine to be linked up; Cooling, lubricating oil pipe 2 are the main entrance of whole boring head cooling, lubricating oil, by the oil pipe access cooling fluid at boring bar center; Guide holder 4 is the bore hole guiding parts, by being contained in 12 birch support guides on the guiding wood seat.
