Description
Technical field
The present invention relates to the axial workpiece centering machine, especially relate to a kind of portable lathe that is used for the processing of axial workpiece centre bore.
Background technology
Centre bore is the benchmark of axis products processing, and first procedure of Machining of Shaft-type Parts is exactly a centering, but does not have easy and high-efficiency method is processed all the time.Traditional processing method is to utilize the rotation of lathe clamping workpiece one end, with tailstock main shaft dress center bit centering.If the major axis series products also will add centre frame on the support level frame earlier, with tailstock main shaft dress centre drill centering, waste time and energy again.Run into large-scale, eccentric serious, the irregular product of external form and then need go up the lathe centering again through the line alignment, its cost is quite big.
Summary of the invention
The invention provides a kind of small-sized portable lathe that is used for the processing of axial workpiece centre bore.
This portable lathe that is used for the processing of axial workpiece centre bore provided by the invention comprises three-jaw self-centering chuck, fuselage, main shaft guide pin bushing, gear shaft, handwheel, drilling rod, spline housing, motor, drill chuck and center bit; Said self-centering chuck is installed in the front end of fuselage, and motor is installed in the rear end of fuselage; Said fuselage is offered centre bore, and main shaft guide pin bushing, gear shaft, drilling rod, spline housing and drill chuck are installed in this hole; The output shaft of motor stretches in the said centre bore and is connected with spline housing, cover drilling rod in the front end of spline housing, and the middle part overcoat main shaft guide pin bushing of drilling rod, front end connect drill chuck, the front end face mounting center drill bit of drill chuck; Gear shaft is installed on the fuselage, is positioned at a side of main shaft guide pin bushing, and it is meshed with tooth bar on the main shaft guide pin bushing, and handwheel sleeve is in the outer end of gear shaft.
The center line of the output shaft of said motor, main shaft guide pin bushing, spline housing, drilling rod, drill chuck, center bit and three-jaw self-centering chuck and the central lines of fuselage centre bore.
Said spline housing band internal spline.
The present invention compared with prior art; Have that overall weight is light, volume is less; Carry more conveniently, can be directly workpiece be installed in the advantage of finding out the center of workpiece on the three-jaw self-centering chuck of front fuselage, for vast machinery production enterprise brings efficient economic processing convenient.Because driving member main shaft guide pin bushing of the present invention and spline housing, the assembly parts of drilling rod and drill chuck and center bit are installed in the centre bore of fuselage, gear shaft is positioned at a side of main shaft guide pin bushing; Through the tooth bar transmission, the motion that moves through handwheel of gear shaft drives, so entire equipment is simple in structure between the two; Operate also simple; Weight is also light, can directly equipment be taken to the workpiece place as required, workpiece is installed to the center of fast finding out workpieces on the three-jaw self-centering chuck of front fuselage; Shake handwheel and can get qualified centre bore, time saving and energy saving.Especially large-scale, complicated product, it is obvious more that superiority of the present invention embodies.
Description of drawings
Fig. 1 looks sketch map for master of the present invention.
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2, the present invention includes three-jaw self-centering chuck 1, fuselage 2, main shaft guide pin bushing 3, gear shaft 4, handwheel 5, drilling rod 6, spline housing 7, motor 8, drill chuck 9 and center bit 10; Said three-jaw self-centering chuck 1 is installed in the front end of fuselage 2, and motor 8 is installed in the rear end of fuselage 2; Said fuselage 2 is offered centre bore 21, and main shaft guide pin bushing 3, gear shaft 4, drilling rod 6, spline housing 7 and drill chuck 9 are installed in this hole; The output shaft 11 of motor 8 stretches in the said centre bore 21 and is connected with spline housing 7, cover drilling rod 6 in the front end of spline housing 7, and the middle part overcoat main shaft guide pin bushing 3 of drilling rod 6, front end connect drill chuck 9, the front end face mounting center drill bit 10 of drill chuck 9; Gear shaft 4 is installed on the fuselage 2, is positioned at a side of main shaft guide pin bushing 3, and it is meshed with tooth bar 31 on the main shaft guide pin bushing 3, and handwheel 5 is enclosed within the outer end of gear shaft 4; The central lines of the center line of the output shaft 11 of motor 8, main shaft guide pin bushing 3, spline housing 7, drilling rod 6, drill chuck 9, center bit 10 and self-centering chuck 1 and fuselage 2 centre bores 21; Spline housing 7 band internal splines.
In conjunction with Fig. 1, Fig. 2; Earlier workpiece is installed in the center of finding out workpiece on the three-jaw self-centering chuck 1, starter motor 8 then, and the output shaft 11 of motor 8 drives spline housing 7 rotations; Thereby spline housing 7 drives drilling rod 6 rotations, and drilling rod 6 drives center bit 10 rotation at a high speed through drill chuck 9; Shake handwheel 5; 4 rotations of handwheel 5 driven gear axles; Transmit, drive main shaft guide pin bushing 3 motion forward in fuselage hole 21 through tooth bar 31, main shaft guide pin bushing 3 drives drilling rod 6 motions, travels forward with center bit 10 thereby drive drill chuck 9; Because qualified centre bore can be got in the center of the center of drilling rod 6, the center of drill chuck 9, center bit 10 and the center of three-jaw self-centering chuck 1 on same horizontal linear.Oppositely shake handwheel 5, main shaft fairlead 3 is moved backward, drive drilling rod 6, drill chuck 9 and center bit 10 and retreat, disable motor 8 unclamps three-jaw self-centering chuck 1, takes out workpiece and gets final product.
