Abstract
The utility model provides a boring bar device for a large span coaxial hole group. The boring bar device is characterized by comprising a boring and milling power head, a shaft coupling, a spherical hinge connecting bar, a lengthened boring bar, sliding bearings and fixed bracket components, wherein the boring and milling power head, the shaft coupling, the spherical hinge connecting bar and the lengthened boring bar are sequentially connected through flanges; square holes are formed in the two end parts of the lengthened boring bar; the sliding bearings and the fixed bracket components are positioned on the lengthened boring bar; the sliding bearings are positioned at two ends of the lengthened boring bar; the two fixed bracket components are clung to the side surfaces of the sliding bearings respectively. According to the boring bar device for the large span coaxial hole group, as the sliding bearings are assembled by the lengthened boring bar and matched with the fixed bracket components simultaneously and bolts are arranged in the positioning bracket components to satisfy the processing requirement of large span workpieces, the processing precision is improved greatly; when the boring bar device is in use, all that needed is to adjust the positioning bracket components and the bolts in the positioning bracket components, the boring is facilitated and the operation is quite simple.
Description
Technical field
The utility model belongs to processing equipment technical field, relates in particular to the boring bar device of a kind of large span axiality hole group.
Background technology
At present, for large-scale engineering machinery and large scale hoisting machinery, often run into when mounted the fraising connection of rotating of large span, so the axiality of both sides hinge hole processing directly has influence on precision of equipment installation and running quality, required precision is higher.Existing processing method precision is too low, and axiality both cannot accurately be controlled also and cannot accurately measure, and directly had influence on the product quality of home-made model.For this reason, it is a kind of for processing the boring bar device of large span axiality hole group that application number is that 200920278303.4 Chinese patent discloses, and it is characterized in that: comprise unit head flange, shaft coupling, boring bar flange, boring bar one, boring bar two, locating support assembly and connecting rod; One end of shaft coupling connects unit head flange, and the other end is connected with boring bar one by boring bar flange; The other end of boring bar one connects locating support assembly one and is connected with connecting rod; The other end of connecting rod is connected with boring bar two; The other end of boring bar two connects locating support assembly two.This patent couples together two boring bars to adapt to the processing request to large span workpiece by connecting rod, and has improved machining accuracy.The both sides of described connecting rod are provided with wear-resisting support set assembly.But just because of it, with connecting rod, two boring bars are coupled together, caused processed complex, inconvenience is installed, also affected machining accuracy, and its wear-resisting support set assembly is to be assembled by a plurality of findings, processing is inconvenient, error is larger simultaneously.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides the boring bar device of a kind of large span axiality hole group, it is characterized in that comprising boring and milling unit head, shaft coupling, ball pivot connecting rod, lengthen boring bar, sliding bearing and m, described boring and milling unit head, shaft coupling, ball pivot connecting rod is connected by flange successively with lengthening boring bar, described lengthening boring bar both ends are provided with square hole, described sliding bearing and m are positioned on described lengthening boring bar, two described sliding bearings are positioned at described lengthening boring bar two ends, two described ms are fitted with described sliding bearing side respectively.
Adjusting bolt in described m is over against described sliding bearing periphery.
The beneficial effects of the utility model are: lengthening boring bar is the slender axles through grinding, guarantee linearity, utilize to lengthen boring bar and substituted original two boring bars and connecting rod, have simplified overall structure, make, easy for installation; Utilize sliding bearing to substitute wear-resisting support set assembly, sliding bearing is the standard component of buying on the market, and error is significantly less than wear-resisting support set assembly, also, without processing and assembling, has saved man-hour, has improved machining accuracy.The utility model is by lengthening boring bar assembling sliding bearing, be fixed bracket component simultaneously, and in locating support assembly, bolt is set, to adapt to the processing request to large span workpiece, greatly improve machining accuracy, during use, only needed to regulate locating support assembly and inner bolt thereof, just can carry out bore hole, operate very simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, boring and milling unit head; 2, shaft coupling; 3, ball pivot connecting rod; 4, lengthen boring bar; 5, sliding bearing; 6, m; 7, workpiece.
As shown in Figure 1, boring and milling unit head 1, shaft coupling 2, ball pivot connecting rod 3 and lengthening boring bar 4 are connected by flange successively, lengthen boring bar 4 both ends and be provided with square hole, sliding bearing 5 and m 6 are positioned at and lengthen on boring bar 4, two sliding bearings 5 are positioned at and lengthen boring bar 4 two ends, lengthening boring bar 4 both sides closely cooperates and is integral with sliding bearing 5 respectively, two ms 6 are fitted with sliding bearing 5 sides respectively, and the adjusting bolt in m 6 is over against sliding bearing 5 peripheries.
During use, both sides m 6 is fixed on workpiece 7, with the hole rough alignment of need processing, then by adjusting the extension elongation of adjusting bolt in m 6, comes accurate centering to lengthen the position of boring bar 4 and sliding bearing 5; Lengthen boring bar 4 both ends and be equipped with square hole, cutter is loaded in the square hole lengthening on boring bar 4, in 90 ° of directions, with sunk screw, compresses, and just can process hole.Change tool length can process the aperture of different size; The position of conversion cutter on lengthening boring bar 4 or the length of lengthening boring bar 4, can adapt to the span requirement in hole.
By embodiment, to of the present utility model, have been described in detail above, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
