Description
Technical field
The utility model is applicable to axle positioning clamp for machining field, refers more particularly to a kind of positioning fixture for automotive transmission axostylus axostyle.
Background technology
Speed changer axostylus axostyle is the important driving parts in speed changer, and all rotating parts in speed changer are all contained on axle, and are able to mutual location by axle, so the quality of speed changer axostylus axostyle precision will directly affect the transmission of whole speed changer.In prior art, man-hour is being added to axostylus axostyle, first axostylus axostyle is being positioned, axostylus axostyle lower end is being stretched in the locating hole in positioning jacket, upper end is being processed, if axostylus axostyle is long, when processing it, axis body can be made to produce violent oscillatory motion, easily there is eccentric situation in workpiece, the gear processed will be caused like this to occur eccentric, thus have a strong impact on crudy, be badly in need of solving the problems of the technologies described above for this reason.
Utility model content
What the utility model solved is add man-hour to axostylus axostyle in prior art, because fixture positioning precision is not high, axis body can be made to produce violent oscillatory motion, thus affect the technical problem of crudy.
In order to solve the problems of the technologies described above, the utility model provides a kind of positioning fixture for automotive transmission axostylus axostyle, comprise positioning jacket, the locating hole matched with axostylus axostyle is provided with in positioning jacket, also comprise locking device, locating centre seat, locating centre, locating centre fixed cover, connecting bolt and Compress Spring, positioning jacket is threaded connection and is fixed on locating centre seat, locating centre fixed cover has a holding tank, Compress Spring is provided with in this holding tank, locating centre is provided with on Compress Spring, connecting bolt runs through locating centre fixed cover and Compress Spring is threaded in locating centre, locating centre fixed cover is threaded in bottom locating centre seat, locating centre extends upwardly in locating hole, described locking device comprises the spacing hole be located on locating centre and the lock pin be slidably connected on locating centre seat, be stuck in spacing hole by lock pin, locating centre is fixed on locating centre seat.
Adopt technique scheme, when positioning fixture to speed changer axostylus axostyle, axostylus axostyle is put in locating hole, by screw, positioning jacket and locating centre seat are fixed again, be provided with in locating centre fixed cover and realize by Compress Spring the locating centre that moves up and down, locating centre fixed cover is screwed in locating centre seat, makes locating centre extend among the axis hole of speed changer axostylus axostyle, realize accurately locating.For the axostylus axostyle of different length, the restoring force by the Compress Spring below locating centre makes the axostylus axostyle of locating centre to different length position.After location, be stuck in the spacing hole of locating centre by lock pin, thus avoiding in process, what spring produced it rocks.So, speed changer axostylus axostyle inside is fixed by locating centre, and outside is clamped by positioning jacket, so when processing, effectively reduce the shaking volume of axostylus axostyle, and the problem that the crudy caused is not good.
Further, be connected for the ease of the axial thread of positioning jacket with locating centre seat, described positioning jacket is designed to up-small and down-big cone.
Further, the center line of locating centre, positioning jacket, locating centre fixed cover and connecting bolt keeps point-blank.Locating centre is navigated in the axis hole of speed changer axostylus axostyle accurately.
Further, described connecting bolt and locating centre fixed cover are matched in clearance.Be convenient to the dismounting of connecting bolt and locating centre fixed cover.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model for the positioning fixture of automotive transmission axostylus axostyle;
Fig. 2 is the structural representation of locating centre in the present embodiment.
Detailed description of the invention
As shown in Figure 1, the technical program provides a kind of positioning fixture for automotive transmission axostylus axostyle, comprise positioning jacket 1, be provided with the locating hole matched with axostylus axostyle in positioning jacket 1, this positioning fixture also comprises locating centre seat 3, locating centre 2, locating centre fixed cover 5, connecting bolt 6 and Compress Spring 4.Positioning jacket 1 is up-small and down-big cone, its lower end is fixedly connected with locating centre seat 3 by axially arranging screw, locating centre fixed cover 5 has a holding tank, Compress Spring 4 is installed in this holding tank, locating centre 2 is provided with on Compress Spring 4, connecting bolt 6 runs through locating centre fixed cover 5 and Compress Spring 4 is threaded in locating centre 2, and locating centre fixed cover 5 is threaded in bottom locating centre seat 3, and locating centre 2 extends upwardly in locating hole.In addition, the center line of locating centre 2, positioning jacket 1, locating centre fixed cover 5 and connecting bolt 6 should keep point-blank.
As shown in Figure 2, described locking device comprises the spacing hole 8 be located on locating centre 2 and the lock pin 7 be slidably connected on locating centre seat, the vertical direction of locating centre 2 evenly offers several spacing hole 8.On locating centre seat 3, horizontal slip is connected with lock pin 7, by being inserted in spacing hole 8 by lock pin 7, thus realizes locating centre 2 to be firmly fixed on locating centre seat 3.
When positioning fixture to speed changer axostylus axostyle, axostylus axostyle is put in locating hole, by screw, positioning jacket 1 and locating centre seat 3 are fixed again, be provided with in locating centre fixed cover 5 and realize by Compress Spring 4 locating centre 2 that moves up and down, locating centre fixed cover 5 is screwed in bottom locating centre seat 2, make locating centre 2 extend among the axis hole of speed changer axostylus axostyle, realize accurately locating.For the axostylus axostyle of different length, the restoring force by the Compress Spring 4 below locating centre 2 makes the axostylus axostyle of locating centre 2 pairs of different lengths position.After location, be stuck in the spacing hole 8 of locating centre 2, thus avoid in process by lock pin 7, what spring 4 produced it rocks.So, speed changer axostylus axostyle inside is fixed by locating centre 2, and outside is clamped by positioning jacket 1, so when processing, effectively reduce the shaking volume of axostylus axostyle, and the problem that the crudy caused is not good.
