As shown in Figure 1, Fig. 1 is the structural schematic diagram of elastic expansion-sleeve clamp structure according to the present utility model.According to this reality
With a kind of elastic expansion-sleeve clamp structure of novel specific implementation mode, it to be used for powder metallurgy synchronizer tooth hub smart car, elastic expanding
Sleeve clamp structure include clamp body 1, pull rod shaft 2, rod head 4, bulb 5, taper body 6, multiple guide posts 7, ringfeder fixed plate 9,
Ringfeder gland 10, elastic expansion-sleeve 12, terminal pad 8 and locating pad 11.Clamp body 1 is fixed, and clamp body 1 has center
Hole is installed with pull rod shaft 2 in centre bore.One end of pull rod shaft 2 is in contact with one end of rod head 4, the outer diameter of rod head 4
Internal diameter with 1 center of clamp body sky is clearance fit.One end of bulb 5 and another end in contact of rod head 4, while bulb 5
It is connect with pull rod shaft 2 by screw.Rod head 4 has center hole, and washer 3 is also nested in center hole, and washer 3 is practical
Between pull rod shaft 2 and bulb 5.One end of taper body 6 has ring flange, has multiple through-holes on ring flange, ring flange
It is connect on one side with the front end face of clamp body 1 by bolt, the other end of taper body 6 has taper.Multiple guide posts 7 are arranged in taper
In multiple through-holes of 6 ring flange of body, one end of multiple guide posts 7 is connect by screw with the other end of rod head 4.Multiple guide posts
7 other end is in contact with one end of ringfeder fixed plate 9.Ringfeder fixed plate 9 toward outer contacting is again ringfeder gland 10, ringfeder pressure
Lid 10 and ringfeder fixed plate 9 are connected by screw with the other end of multiple guide posts 7.One end of elastic expansion-sleeve 12 has flange,
The inner edge diameter of ringfeder gland 10 is less than the outer diameter of 12 1 end boss of elastic expansion-sleeve, in this way, when ringfeder gland 10 and ringfeder are fixed
After plate 9 is connected by screw with the other end of multiple guide posts 7, the flange of 12 one end of elastic expansion-sleeve is also just locked in ringfeder pressure
Between lid 10 and ringfeder fixed plate 9, but ringfeder fixed plate 9 and ringfeder gland 10 compress after between the flange of elastic expansion-sleeve 12
Axial also there are the gaps 0.05~0.15mm, can ensure that elastic expansion-sleeve 12 can carry out axial turn before complete locking in this way
It is dynamic.The one side of terminal pad 8 is connect with the another side of ring flange, and terminal pad 8 has center hole.One end of locating pad 11 and connection
The another side of disk 8 connects, and the other end of locating pad 11 has with boss, with multiple grooves 14, the end face of boss on boss
For positioning surface 15 (please referring to Fig. 2).
In some embodiments, there is the other end of rod head 4 spherical concave surface, one end of bulb 5 to have spherical male
Face, spherical concave surface is abutted with spherical convex surface cooperation, and can mutually be slided with spherical surface.
In some embodiments, clamp body 1 and taper body 6 are all fixed, and pull rod shaft 2 can drive bulb 5 and draw
Knock-off joint 4 slides back and forth in the centre bore of clamp body 1, so that rod head 4 drives multiple guide posts 7 in multiple through-holes
It slides back and forth, finally enables multiple guide posts 7 that elastic expansion-sleeve 12 is driven to be moved forward and backward along taper body 6.
In some embodiments, the other end of elastic expansion-sleeve 12 is in petal-like structures, and the inner wall of petal-like structures is formed
With tapered taper hole, the taper of taper hole is corresponding with the taper of taper body 6；When elastic expansion-sleeve 12 is moved forward and backward along taper body 6
When, taper body 6 enables to petal design spreading or closure.
In some embodiments, one end of locating pad 11 has accommodating hole, the center hole structure of accommodating hole and terminal pad 8
At accommodating space, accommodating space is the mobile space of elastic expansion-sleeve 12.
In actual utilization, pass through pull rod shaft in rotary cylinder or angling cylinder (the utility model is not limited thereto)
2 driving elastic expansion-sleeves 12 make 12 distending of elastic expansion-sleeve clamp workpiece 13 to the movement of lathe spindle direction, otherwise workpiece 13 is unclamped in side
When, using multiple guide posts 7 and bulb 5, washer 3, rod head 4 and ringfeder fixed plate 9 between pull rod shaft 2 and elastic expansion-sleeve 12
It is connected with ringfeder gland 10, the outer diameter of rod head 4 reciprocatingly slides along the internal diameter of 1 centre bore of clamp body at this time, multiple to lead
Column 7 reciprocatingly slides in multiple through-holes of 6 ring flange of taper body, since bulb 5 and rod head 4 are sphere-contacts, thus
It can effectively prevent coupling because of 2 end face squareness of pull rod shaft and with pull rod shaft 2 and actuating unit (rotary cylinder or angling cylinder)
Thread coaxiality problem, the influence to 12 distending uniformity of elastic expansion-sleeve.Elastic expansion-sleeve 12 clamp position using spline structure with
Synchromesh gear hub internal spline tooth socket is corresponding, swelling internal spline major diameter when clamping, can effectively prevent when turning that power is excessive to cause work
Part 13 and fixture go out sliding phenomenon, are scrapped so as to cause workpiece 13 and tool damage.
In some embodiments, after ringfeder fixed plate 9 and ringfeder gland 10 compress between the flange of elastic expansion-sleeve 12
Axial also there are the gaps 0.05~0.15mm, and elastic expansion-sleeve 12 can rotate back and forth workpiece 13 before complete tensioner and position mould
15 residual scrap iron of face takes in the radial groove 14 of the positioning surface 15 of locating pad 11, prevents residual scrap iron from holding up workpiece 13, and
Cause 13 axial dimension of workpiece overproof.Taper body 6 coordinates taper to be 1 with elastic expansion-sleeve 12：5, elastic expansion-sleeve 12 clamps workpiece 13
When workpiece 13 can be driven to be moved to the positioning surface 15 of mould, therefore not by workpiece when can effectively prevent operator's card engaging workpiece 13
13 with 15 generation that is sturdy and leading to product axial dimension off-gage phenomenon of positioning surface of mould.Elasticity is only needed to change when replacing product
Ringfeder 12 and locating pad 11 not only shorten tooling replacing construction but also reduce tooling manufacturing cost, also increase simultaneously
Versatility.
In conclusion being proven this 12 fixture of powder metallurgy synchronizer tooth hub elastic expansion-sleeve, repeat to clamp workpiece 13
Axial precision in 0.005mm hereinafter, radial accuracy in 0.04mm hereinafter, the therefore elastic expansion-sleeve clamp structure energy of the utility model
Enough given birth in smart car synchromesh gear hub process is applied well, and successfully replaces grinding machine processing to reduce production with turnery processing
Product production cost.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of different examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
Formula is limited.
