Abstract
A kind of radial drilling machine modified main shaft, comprising: main shaft, its feature is: power transmission shaft is installed in main shaft inside, Biserial cylindrical roller bearing is installed in one end of main shaft, Biserial cylindrical roller bearing dottle pin, circlip for hole and dust-proof cushion, rack sleeve is installed in main shaft outside, rack sleeve installs fairlead, hexagon socket cap head screw, the other end of main shaft installs deep groove ball bearing, Double-lip framework oil sealing, interior hexagonal cone end holding screw, deep groove ball bearing dottle pin, thrust ball bearing, spacer, round nut stop washer, round nut, spline housing, the utility model has the advantages that: reduce spindle deformation and non-easy damaged main shaft, main shaft has automatic tool withdrawal function.
Description
Technical field
The utility model relates to a kind of radial drilling machine, particularly relates to a kind of radial drilling machine modified main shaft.
Background technology
Existing radial drilling machine main shaft is general more elongated, yielding, and radial drilling machine main shaft is also without automatic tool withdrawal function, and radial drilling machine main shaft is easy damaged main shaft in withdrawing process.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly reduces spindle deformation and non-easy damaged main shaft, main shaft have the radial drilling machine modified main shaft of automatic tool withdrawal function.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of radial drilling machine modified main shaft, comprising: main shaft, its feature is: power transmission shaft is installed in main shaft inside, Biserial cylindrical roller bearing, Biserial cylindrical roller bearing dottle pin, circlip for hole and dust-proof cushion are installed in one end of main shaft, rack sleeve is installed in main shaft outside, rack sleeve is installed fairlead, hexagon socket cap head screw, the other end of main shaft installs deep groove ball bearing, Double-lip framework oil sealing, interior hexagonal cone end holding screw, deep groove ball bearing dottle pin, thrust ball bearing, spacer, round nut stop washer, round nut, spline housing.
The utility model has the advantages that: the splined shaft of main shaft on radial drilling machine is changed into separate type, and inversion is arranged on radial drilling machine, add oil storage place simultaneously, reduce the wearing and tearing of deep groove ball bearing, extend the service life of main shaft, when main shaft lifting certain altitude of the present utility model, the drill taper shank installed below main shaft will bump against power transmission shaft, drill taper shank is stressed to come off from main shaft, before comparing, radial drilling machine main shaft is without automatic tool withdrawal function, decrease operational ton, save time, improve working (machining) efficiency, avoid knocking main shaft simultaneously, the not yielding damage simultaneously reducing main shaft of main shaft, make radial drilling machine processing parts more stable, improve the machine tool accuracy of radial drilling machine.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described:
A kind of radial drilling machine modified main shaft, as shown in Figure 1, comprising: main shaft 11, its feature is: power transmission shaft 10 is installed in main shaft 11 inside, Biserial cylindrical roller bearing 14 is installed in one end of main shaft 11, Biserial cylindrical roller bearing dottle pin 16, circlip for hole 17 and dust-proof cushion 18, rack sleeve 12 is installed in main shaft 11 outside, rack sleeve 12 is installed fairlead 13, hexagon socket cap head screw 15, the other end of main shaft 11 installs deep groove ball bearing 9, Double-lip framework oil sealing 8, interior hexagonal cone end holding screw 7, deep groove ball bearing dottle pin 6, thrust ball bearing 5, spacer 4, round nut stop washer 3, round nut 2, spline housing 1.
The utility model beneficial effect: the splined shaft of main shaft on radial drilling machine 11 is changed into separate type, and inversion is arranged on radial drilling machine, add oil storage place simultaneously, reduce the wearing and tearing of deep groove ball bearing 9, extend the service life of main shaft 11, when main shaft 11 lifting certain altitude of the present utility model, the drill taper shank installed below main shaft 11 will bump against power transmission shaft 10, drill taper shank is stressed to come off from main shaft 11, before comparing, radial drilling machine main shaft 11 is without automatic tool withdrawal function, decrease operational ton, save time, improve working (machining) efficiency, avoid knocking main shaft 11 simultaneously, the on-deformable damage simultaneously reducing main shaft 11 of main shaft, make radial drilling machine processing parts more stable, improve the machine tool accuracy of radial drilling machine.
Embodiment recited above is only be described preferred embodiment of the present utility model; not design of the present utility model and protection domain are limited; under the prerequisite not departing from the utility model design concept; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement, all should fall into protection domain of the present utility model.
