Abstract
The utility model relates to a fixture for processing a radial hole in a gear shaft of a gearbox. The fixture comprises a hydraulic cylinder, a piston, a disc spring, a live center, the gear shaft, a positioning plate, a fixed center, a spindle, a coupler and a servo motor, wherein the piston is located in the hydraulic cylinder, one end of the piston is used for jacking up a workpiece, and the other end of the piston is connected to the live center through the disc spring; and centering of the gear shaft is performed by the live center and the fixed center under the action of disc spring, at the same time, the positioning plate is used for determining the axial position of the gear shaft and drives the gear shaft to rotate under the drive of the spindle, and the spindle is connected with the servo motor through the coupler. The fixture for processing the radial hole in the gear shaft of the gearbox is compact in integral structure, capable of accurately clamping and positioning the gear shaft and capable of realizing high-accuracy rotary indexing through the servo motor.
Description
Technical field
The utility model belongs to metal-working plant technical field, more particularly relates to a kind of ring for the special fixture of gearbox gear axle radial hole processing.
Background technology

Utility model content
In order to overcome above-mentioned technical problem, the purpose of this utility model be to provide a kind of can be accurately by gear shaft clamping and positioning, and can realize by servomotor the fixture of the processing gearbox gear axle radial hole of its high-precision circular index.
For achieving the above object, embodiment of the present utility model adopts following technical scheme:
A kind of fixture of processing gearbox gear axle radial hole, it comprises hydraulic cylinder, piston, dish spring, live center, gear shaft, positioning disk, back dead centre, main shaft, shaft coupling and servomotor, wherein said piston is arranged in its one end of described hydraulic cylinder for jack-up workpiece, the other end of described piston is connected to described live center by dish spring, under the active force of described dish spring, described gear shaft is felt relieved by live center and back dead centre, and by described positioning disk, determined the axial location of described gear shaft simultaneously, described positioning disk drives described gear shaft revolution under the driving of described main shaft, described main shaft is connected by between described shaft coupling and described servomotor.
Technique effect of the present utility model is: the fixture compact overall structure of this novel processing gearbox gear axle radial hole, it can be accurately by gear shaft clamping and positioning, and can realize its high-precision circular index by servomotor.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the fixture of processing gearbox gear axle radial hole of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, it shows the concrete structure of the fixture of processing gearbox gear axle radial hole of the present utility model, the fixture of this processing gearbox gear axle radial hole comprises hydraulic cylinder 1, piston 2, dish spring 3, live center 4, gear shaft 5, positioning disk 6, back dead centre 7, main shaft 8, shaft coupling 9, servomotor 10, wherein piston 2 is arranged in described hydraulic cylinder 1, its one end is for jack-up workpiece, the other end of institute's piston 2 is connected to described live center 4 by dish spring 3, under the active force of described dish spring 3, described gear shaft 5 is felt relieved by live center 4 and back dead centre 7, and the while is by the axial location of described positioning disk 6 definite described gear shafts 5, described positioning disk 6 drives described gear shaft 5 revolutions under the driving of described main shaft 8, described main shaft 8 is connected by between described shaft coupling 9 and described servomotor 10.
Operation principle of the present utility model: add man-hour by hydraulic pressure by piston 2 jack-up workpiece in hydraulic cylinder 1, under the active force of dish spring 3, gear shaft 5 is by 7 centering of live center 4 and back dead centre, and by positioning disk 6, determines its axial location simultaneously.Positioning disk 6 can driven gear axle under the driving of main shaft 8. 5 revolutions, and and servomotor 10 between direct-connected by shaft coupling 9, guarantee the rotary position precision of workpiece.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; the technical staff of any skilled is in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
