Abstract
The utility model provides a device for machining a long-distance high-coaxiality bearing hole, which is used for machining the high-coaxiality bearing hole on a bearing seat. The device comprises a boring rod, universal joints and a transmission shaft, wherein one end of the transmission shaft is connected with the boring rod and the other end of the transmission shaft is connected with the universal joints; the bearing seat is provided with an auxiliary supporting shaft seat which can solve the problem that down-warping is generated by poor rigidity of the boring rod; and more than two knife installing holes are arranged on the circumference of the boring rod. The device provided by the utility model has the beneficial effects that the technical scheme is adopted so that the coaxiality error is compensated through the two universal joints; a boring mill main shaft only generates a cutting rotary torque and an axial force which is axially fed; and knives on the boring rod are utilized to machine a hole in the bearing seat. The device disclosed by the utility model has the characteristics of simple mechanism, convenience for machining, reduction of work hours, cost saving, wide applicability and the like.
Description
Technical field
The utility model relates to a kind of rivet welding spare machined, especially relates to a kind of device of processing remote high-axiality dead eye.
Background technology
To the existing large scale computer process equipment (160 floor type boring machine) of our factory, want to guarantee the required precision of drawing, processing is very much difficulty, and axiality is not fine; Add even if also be difficult to machine, and cost is too high with the five-shaft numerical control boring machine.In order to save cost, make things convenient for machine to add, guarantee the drawing precision, thus utility model the logical a plurality of remote dead eyes of boring of a kind of boring bar have axiality to require process program.
The utility model content
The problem that the utility model will solve provides a kind of device of processing remote high-axiality dead eye, especially is fit to be processed with a plurality of remote dead eye that axiality requires.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of device of processing remote high-axiality dead eye, be used for the dead eye of processing high-axiality on bearing block, and comprise boring bar, universal joint and drive shaft; Power transmission shaft one end connects boring bar, and the other end is connected with universal joint; Bearing block is provided with and solves the supplemental support axle bed that the boring bar poor rigidity produces the downwarp problem.
Further, the boring bar circumference is provided with more than 2 and adorns tool bore.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, and through two universal joint compensating coaxial degree errors.Boring spindle only provides the axial force of cutting rotation torque and axial feed.Utilize boring bar to fix a cutting tool machining bearing seat endoporus.Characteristics such as it is simple to have mechanism, processes easyly, has reduced man-hour, practices thrift cost, and applicability is wide.Process program mechanism is simple, realizes easily, as long as the floor type boring machine specification is arranged suitably; The process program applicability is strong, as long as boring bar is enough long, adopts several supplemental support axle beds just can use this scheme more.
Description of drawings
Fig. 1 is the in running order sketch map of the utility model.
Among the figure:
1, frame 2, supplemental support axle bed 3, boring bar
4, gear-box 5, power transmission shaft 6, dress tool bore
7, universal joint 8, bearing block 9, boring spindle
The specific embodiment
As shown in Figure 1, the utility model provides a kind of device of processing remote high-axiality dead eye, is used for the dead eye of processing high-axiality on bearing block 8, comprises boring bar 3, universal joint 7 and power transmission shaft 5; Power transmission shaft 5 one ends connect boring bar 3, and the other end is connected with universal joint 7; Bearing block 8 is provided with and solves the supplemental support axle bed 2 that boring bar 3 poor rigidity produce the downwarp problem.Boring bar 3 circumference are provided with dress tool bore 6 more than 2.
The course of work of this instance: like Fig. 1, frame 1 right-hand member is provided with gear-box 4 near boring spindle 9 one sides, is welded with bearing block 8 on the gear-box 4, with supplemental support axle bed 2 coarse positionings, and welding supplemental support axle bed support; Workpiece is put on the workbench, guarantees that the bottom surface contacts well with workbench.Take away the last FE Tiler of bearing block 8 then, boring bar 3 FE Tiler on the fastener shaft bearing 2 that puts in; With supplemental support axle bed 2 coarse positionings, welding supplemental support axle bed support; Boring machine utilizes the Up Highway UHW and the side bus of the long boring bar of dial gauge centering, and the linearity that guarantees Up Highway UHW and side bus just can be located each supplemental support axle bed 2 in 0.02mm.Each aiding support axle bed 2 is near processed dead eye, to improve the axiality of each bearing saddle bore of processing.Through two universal joints, 7 compensating coaxial degree errors.9 of boring spindles provide the axial force of cutting rotation torque and axial feed.Utilize boring bar 3 to fix a cutting tool machining bearing seat 8 endoporus.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
