Abstract
The utility model relates to a combined boring and rolling head for machining a deep hole. The boring and rolling head comprises a boring head body, cutter body seats, boring cutters, supporting sleeves and a roller, wherein the roller is fixedly connected with the boring head body through a connecting block; a row of balls are arranged on the roller; the cutter body seats are symmetrically arranged at the two ends of the boring head body; the boring cutters are fixedly arranged on the cutter body seats; an included angle is formed between the plane of the boring cutters and the plane of the cutter body seats; and flow guide chip removal grooves are formed at the cutter body seats on the boring head body. By the boring and rolling head, machining efficiency, the finish of a machined surface and rolling quality can be improved, loss can be reduced, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of deep hole deep hole machining dedicated tool, relates in particular to a kind of combined boring head for deep hole.
Background technology
Boring head is a kind of cutter of deep hole processing in the metal processing, is used for the cylinder body processing of oil cylinder more, is a kind of compound tool that boring and roll extrusion can be accomplished processing simultaneously.
Domestic at present, abroad have in mainly employing mode of deep hole machining process: 1, TTG mode (heavy boring+right boring+roll extrusion); 2, TGG mode (half right boring+roll extrusion+roll extrusion); 3, drill gun; 4, hone; 5 other.Wherein 1, the TTG mode process in row cut bad control, workpiece processing back inner surface fineness is difficult for guaranteeing, is prone to waste product, and is bigger as far as large hydraulic oil cylinder cost allowance.Though 2, the TGG mode has overcome the problem that row cuts in the processing to a certain extent, twice roll extrusion workpiece is prone to cause the workpiece inner-wall material tired, defectives such as crackle, peeling occur, is prone to waste product equally.And the ball in the TGG mode on the boring head and the raceway consumption is big, the process-cycle is long, matching requirements are high when being prone to cause long-time shut-down platform.3, drill gun technology is suitable for the less demanding product of workpiece inner wall surface, and is comparatively rare in the processing of major diameter multistage hydraulic cylinder.4, hone processing is high, effective with right machining accuracy, but production efficiency is low, and the consumptive material consumption is big.
The Chinese patent Granted publication number is CN 2905282Y, and Granted publication day is that the utility model patent on May 30th, 2007 discloses a kind of combined boring head for deep hole, and it is that the left side has the boring head body, and there is the connection cutter hub centre, and the right is connected with joint.Push rod is installed in the center that connects cutter hub and big piston; Boring head body the right connects cutter hub and was with last week and is evenly distributed, and is contained in the roller on the tapered sleeve with what key connected; Connecting the cutter hub right side has the supporting disk that is contained on the push rod, and there is big piston on the supporting disk right side, and guide pad is contained on the joint cylindrical; Quick oily joint is installed in the joint; Two and half fine boring cutters are installed on the boring head body Far Left up and down; The fine boring cutter piece that two rectangle is formed is installed on the boring head body of the left side.
Said apparatus belongs to TTG mode (heavy boring+right boring+roll extrusion), and row cut bad control during the TTG mode was processed, and workpiece processing back inner surface fineness is difficult for guaranteeing, is prone to waste product, and is bigger as far as large hydraulic oil cylinder cost allowance.
Summary of the invention
The purpose of the utility model is to overcome the problem that the existing apparatus crudy is poor, loss is high, and a kind of crudy height, the low combined boring head for deep hole of loss are provided.
For realizing above purpose; The technical solution of the utility model is: a kind of combined boring head for deep hole; Comprise boring head body, cutter hub seat, boring cutter, support set and roller, said roller is connected with the boring head body-fixed through contiguous block, and said roller is provided with row's ball; Said boring head body two ends are symmetrically arranged with the cutter hub seat; Be installed with boring cutter on the said cutter hub seat, said boring cutter plane and cutter hub seat planar shaped have angle, and are positioned at cutter hub seat place on the said boring head body and are provided with the water conservancy diversion chip area.
The scope of said angle is 45 °～85 °.
Said support set symmetry is installed on boring head body both sides, and said support set becomes 90 ° of angles with the cutter hub seat.
Said cutter hub seat is adjustable cutter hub seat.
Said ball is an olive shape.
Compared with prior art, the utlity model has following benefit:
1, the utility model adopts TG mode (right boring+roll extrusion) to make, and has reduced by one group of boring cutter, has lowered production cost.
2, the utility model adopts the multiple cut technology on boring head, boring cutter; Be provided with the water conservancy diversion chip area; Improve the cooling effect of lathe rotating speed and process; The boring cutter work in-process forms gradual cutting, under equal processing conditions, can strengthen the cutting speed and the depth of cut, enhances productivity and processed surface smoothness.
3, the cutter hub seat in the utility model is adjustable cutter hub seat, makes the cutter hub seat to adjust according to actual conditions, uses more convenient.
4, in the utility model ball be shaped as olive shape because the structure of olive is unique, can guarantee that roll extrusion is meticulousr, the roll extrusion better quality.
