Abstract
The utility model discloses a boring bar used for processing main bearing holes and thrust surfaces, which comprises five pairs of boring cutter rows arranged in the middle of the boring bar, and a pair of boring cutter rows arranged on a rear toothed plate of the boring bar, and the toothed plate is meshed with a rack on a push rod. The utility model realizes the purpose of processing the main bearing holes of a four-cylinder machine body and the thrust surfaces at both sides of the rear main bearing hole in one step by the special arrangement of the boring cutters, has high processing precision and high working efficiency, and is suitable for mass production .
Description
Technical field
The utility model relates to a kind of machine tools, particularly a kind ofly is used for the boring bar that machining spindle holds hole and thrust surface.
Background technology
The processing of main bearing hole and thrust surface is an important content in the diesel-engine body processing, and machining accuracy and form and position tolerance are all had higher requirements, present processing mode also has multiple, but mostly can not when guaranteeing machining accuracy, also guarantee to process work efficiency, can not realize production in enormous quantities, thereby limit the development of diesel-engine body processing industry.
The utility model content
The purpose of this utility model provides a kind of boring bar that machining spindle holds hole and thrust surface that is used for, have can disposablely process, precision height, work efficiency height and the characteristics that can be mass-produced.
For achieving the above object, by the following technical solutions:
A kind ofly be used for the boring bar that machining spindle holds hole and thrust surface, comprise and arrange five pairs of boring cutter rows that are installed in the boring bar middle part and be installed in a pair of boring cutter row on the tooth plate of boring bar rear end, described tooth plate is meshed with tooth bar on the push rod.
Described boring cutter row is all fixed by trip bolt.
The utility model is arranged on five pairs of boring cutter rows on the boring bar by utilization, has realized dividing the purpose of thick, smart twice processing body main bearing hole, has five boring cutters to cut five grades of main bearing holes simultaneously respectively in the wherein said boring cutter row; Utilization is oppositely arranged on a pair of boring cutter board on the tooth plate, axially reciprocating by push rod drives and does radial expansion and move, under the cooperation that boring bar only rotates, finish turning to the both sides thrust surface, thereby realized the purpose of disposable processing four cylinder body body main bearing holes and one grade of main bearing hole both sides, rear end thrust surface, and machining accuracy height, work efficiency height, be fit to produce in enormous quantities.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
To be that the utility model embodiment is described be used for the positive cross-sectional schematic that machining spindle holds the boring bar of hole and thrust surface to Fig. 1.
Among the figure:
1, boring bar; 2, the boring cutter row at boring bar middle part; 3, push rod; 4, tooth plate; 5, trip bolt.
The specific embodiment
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
As shown in Figure 1, described in the utility modelly be used for the boring bar that machining spindle holds hole and thrust surface, comprise arranging and be installed in five pairs of boring cutter rows 2 at boring bar 1 middle part and be installed in a pair of boring cutter row on the boring bar 1 rear end tooth plate 4, described tooth plate 4 is meshed with tooth bar on the push rod 3, and the boring cutter row 2 and the boring cutter row on the tooth plate at described boring bar middle part are all fixed by trip bolt 5.
During use, pass through the main shaft orientation of boring bar 1 earlier, then boring bar 1 is stretched into workpiece to be processed and carry out the worker and advance, main bearing hole is carried out thick, smart twice processing, and boring bar 1 stops to move and only rotates then, and the rear end boring cutter extends radially out does the crosscut campaign, after machining, the rear end boring cutter radially contracts and moves back, and boring bar 1 rewind down is finished operation then.Workpiece has been finished the turning processing of the twice boring pin and the thrust surface of main bearing hole in one-time positioning and clamping process.
