Abstract
The invention discloses a spline shaft positioning device comprising a positioning device body and a plurality of fastening screws. The positioning device body is in the shape of a cuboid and is internally provided with a positioning cavity penetrating the two opposite end faces of the positioning device body; the four side faces of the positioning device body are each provided with a threaded hole and a positioning hole; a positioning step is arranged on the far inner surface of the positioning cavity; in use, a spline shaft can stretch into the positioning cavity; a bearing retainer and a step of the spline shaft are positioned through the positioning step; pressing is performed through threaded connection of the fastening screws and the threaded holes, and therefore a drill bit can stretch into the positioning holes to drill holes; the positioning device body rotates by 90 degree every time one hole is drilled, and finally, machining of crossed holes is completed; the spline shaft can be firmly positioned, and positioning is not needed again after each time of hole punching; and the structure is simple, and the positioning effect is good.
Description
Technical field
The present invention relates to a kind of positioner, particularly relate to a kind of splined shaft positioner.
Background technology
The fast development manufactured along with China's industry and the progress of mechanical technique, by auto parts and components manufacturing industry also
Having brought the fast traffic lane of high speed development into, the competition of auto parts and components manufacture field is the most more and more fierce, has entered
Entering low margin age, this present situation forces mechanical processing industry constantly to innovate and to improve, and abandons conventional height
Power consumption, high consumptive material, high labor intensity and the mode of production of poor efficiency, positive searching is saved energy and reduce the cost, and saves
The new method of manpower and materials.
Splined shaft is a key components and parts on automobile, the same, all with flat key, woodruff key, taper key effect
Being transmission mechanical torque, the appearance at axle has longitudinal keyway, and the revolving part being enclosed within axle also has correspondence
Keyway, can keep with axle synchronous rotary.While rotating, have can also make longitudinal sliding motion on axle,
Such as gearbox gear-shift gear etc..
In actual production, the end of splined shaft typically requires making cross bore, and this is accomplished by entering splined shaft
Row location.Existing splined shaft positioner general structure is complicated, and is required for reorientating after each punching,
Complex operation, affects locating effect, and then affects drilling technology.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of splined shaft positioner, splined shaft can be carried out jail
Solid location, and every time after punching without again positioning, simple in construction, good positioning effect.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of splined shaft positioner, including positioner body and several trip bolt；Described positioner
Body is rectangular-shaped, and inside is provided with the positioning chamber running through two relative end faces of described positioner body；
Four sides of described positioner body be respectively equipped with near described positioner body one end screwed hole with
And the hole, location near the described positioner body other end；Described trip bolt is with described screwed hole screw thread even
Connect；Described positioning chamber is provided with positioning step away from the inner surface of one end, hole, described location.
The quantity of described trip bolt and screwed hole is four；Each side of described positioner body is equal
It is provided with a screwed hole.
The axis of four screwed holes on the side of described positioner body intersects vertically.
The quantity in hole, described location is four；Each side of described positioner body is equipped with a location
Hole.
The axis in the hole, four location on described this body side surface of positioner intersects vertically.
Advantage for present invention with effect is:
The splined shaft positioner of the present invention, including positioner body and several trip bolt；Positioner
Body is rectangular-shaped, and inside is provided with the positioning chamber running through two relative end faces of positioner body；Location
Four sides of device body set screwed hole and hole, location respectively；The remote inner surface of positioning chamber is provided with positioning step；
Splined shaft can be stretched into positioning chamber during use, utilize positioning step to carry out determining to bearing guard and the step of splined shaft
Position, and compressed with threadeding of screwed hole by trip bolt, thus drill bit is stretched into hole, location and enters
Row boring, is often drilled a hole by positioner body 90-degree rotation, is finally completed the processing of cross bore；Can
Splined shaft is firmly positioned, and without again positioning after each punching, simple in construction, locating effect
Good.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:
Fig. 1 is the generalized section of the splined shaft positioner of the present invention；
Fig. 2 is the axonometric chart of the splined shaft positioner of the present invention.
In figure: positioning chamber 1, positioning step 2, screwed hole 3, trip bolt 4, location hole 5, splined shaft
10, drill bit 20, positioner body 30.
Detailed description of the invention
As shown in Figure 1 to Figure 2, the present invention provides a kind of splined shaft positioner, including positioner body
30 and several trip bolt 4.Positioner body 30 is in rectangular-shaped, and inside is provided with runs through positioner originally
The positioning chamber 1 of two end faces that body 30 is relative.Four sides of positioner body 30 are respectively equipped with close
The screwed hole 3 of positioner body 30 one end and the hole, location 5 of close positioner body 30 other end.
Trip bolt 4 is threadeded with screwed hole 3.Positioning chamber 1 sets away from the inner surface of one end, hole 5, described location
Positioning step 2, positioning step 2 is had to adapt with the bearing guard of splined shaft 10 and the shape of step, with convenient
Splined shaft 10 is positioned.
Specifically, the quantity of trip bolt 4 and screwed hole 3 is four；Positioner body 30 each
Side is equipped with a screwed hole 3.The axis of four screwed holes 3 on the side of positioner body 30 hangs down
Straight crossing, with threadeding of screwed hole 3, splined shaft 10 can be compressed by trip bolt 4, strengthen
The effect of location.
Specifically, the quantity in hole 5, location is four；Each side of positioner body 30 is equipped with one
Hole 5, location.The axis in the hole 5, four location on positioner body 30 side intersects vertically, and can pass through will
Drill bit 20 stretches into hole 5, location and holes splined shaft 10, is often drilled a hole by positioner body 30
90-degree rotation, is finally completed the processing of cross bore, and every time after punching without again positioning, simple in construction,
Good positioning effect.
The present invention is not limited to above-described embodiment, and embodiment is exemplary, it is intended to be used for explaining the present invention,
And be not considered as limiting the invention.
