Description
Technical field
The utility model belongs to machining fixture technical field, and in particular to a kind of brill of splined shaft pinhole easy to process
Set.
Background technique
Just like pin shaft connection type shown in Fig. 4 in the installing and using of gear pump, due to the presence of spline teeth, in tooth
Relative position both when the main tooth splined shaft of wheel pump is connected with connector sleeve is also just fixed, this requires that selling on spline housing and axis
The position in hole wants relatively uniform, in actual processing we provide the position of pin hole in the middle position of two tooth forms, as shown in Figure 5.
But if directly processed in actual processing, the middle position of two tooth forms of splined shaft is not easy centering, and pinhole is easy to bore partially,
Assembly is influenced, and processing efficiency is also low.
Summary of the invention
Place, the utility model provide a kind of splined shaft pinhole easy to process in order to overcome the above-mentioned deficiencies of the prior art
Drill bushing.
The utility model is achieved by the following technical solution: a kind of drill bushing of splined shaft pinhole easy to process, packet
Rectangular chuck clamping axis is included, chuck clamps the spindle nose putting hole that axis is equipped with blind hole structure, is held by a chuck the end of axis
The side that do not penetrate through of face to spindle nose putting hole is equipped with threaded hole I, is equipped with adjusting screw in threaded hole I；The one of chuck clamping axis
Side is additionally provided with the drill jig sets of holes and threaded hole II for penetrating into spindle nose putting hole, is equipped with drill jig sleeve, threaded hole II in drill jig sets of holes
Positioning screw is inside installed, the bathtub construction between the end construction of positioning screw and two teeth of processed splined shaft matches；
It is at least vertical with one adjacent side that chuck clamps side of the axis equipped with drill jig sets of holes and threaded hole II.
Further, the spindle nose putting hole is 0.10~0.15mm bigger than the major diameter of processed splined shaft.
Further, the sides adjacent of the side holding vertical relation of drill jig sets of holes and threaded hole II is equipped with chuck clamping axis
Face includes the side that centerline hole keeping parallelism relationship is placed with spindle nose.
Drilling processing is carried out the beneficial effects of the utility model are: splined shaft is located in the spindle nose putting hole of drill bushing,
It can facilitate on splined shaft, accurately and fast process the higher pinhole of position degree.

Specific embodiment
Below according to drawings and examples, the present invention will be further described.
As shown in Figure 1 to Figure 3, a kind of drill bushing of splined shaft pinhole easy to process is clamped including rectangular chuck
Axis 2, chuck clamp the spindle nose putting hole 7 that axis 2 is equipped with blind hole structure, are held by a chuck the end face of axis 2 to spindle nose putting hole 7
Side is not penetrated through and is equipped with threaded hole I, is equipped in threaded hole I and adjusts screw 1, adjusts the axis that screw 1 adjusts the pinhole of splined shaft
To position；The drill jig sets of holes and threaded hole II for penetrating into spindle nose putting hole 7, i.e. drill jig are additionally provided in the side of chuck clamping axis 2
The radial position of spindle nose putting hole 7 is arranged in sets of holes and threaded hole II, is equipped with drill jig sleeve 5 in drill jig sets of holes, in threaded hole II
Positioning screw 6 is installed, the bathtub construction between the end construction of positioning screw 6 and two teeth of processed splined shaft matches；
It is at least vertical with one adjacent side that chuck clamps side of the axis 2 equipped with drill jig sets of holes and threaded hole II.As shown in figure 3, drill jig
Sets of holes and threaded hole II are located at the side of horizontal plane 3, wherein the plane perpendicular with horizontal plane 3 is for horizontal plane
3 carry out the verification plane 4 of level correction.
Further, the spindle nose putting hole 7 is 0.10~0.15mm bigger than the major diameter of processed splined shaft.
As the improvement of the present embodiment, as shown in figure 3, to horizontal plane 3 carry out level correction verification plane 4 be with
The side of 7 center line keeping parallelism relationship of spindle nose putting hole, to facilitate the correction in drill bushing horizontal location.
The utility model use process: the middle line position of index chuck and small-sized tailstock is adjusted on vertical knee-type milling machine first
It sets, and according to drawing requirement pin hole to the distance of spline shaft end, adjustment adjusts screw, then with the card of index chuck clamping drill bushing
Disk folder holds axis, and estimates adjustment level, next the pedestal for verifying dial gauge is adsorbed on the workbench of vertical knee-type milling machine, percentage
Table contact and returns to zero percentage list index to the verification plane of drill bushing, then moves up and down the workbench of vertical knee-type milling machine, reads
Deviate numerical value, then accordingly adjusts index chuck claming angle, and the workbench for moving up and down vertical knee-type milling machine again carries out school
It tests, until dial gauge do not have deviation, shows the verification plane of drill bushing absolute upright.Horizontal plane and verification due to drill bushing
Plane be it is completely vertical, the horizontal plane of drill bushing is also indicated that after the completion of verification, and also adjustment is horizontal.Then splined shaft is installed
To the spindle nose putting hole of drill bushing, tail portion is withstood with small-sized tailstock central axis, the circumferentially positioned screw of splined shaft is then tightened, due to this
The end construction color keyway shape of screw matches, and splined shaft both ends are all that top is held, so in the mistake of the screw-driving
The center position of two tooth form of splined shaft also determines that centering in journey, next adjusts drill bit to the position of drill jig sleeve, directly drills through
?.
Next the method only needs the workpiece that changes the outfit, tightens the positioning of splined shaft circumferential direction after drill bushing position adjusts
Screw greatly improves work efficiency, while also ensuring the position of pinhole.
