Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings.

As shown in fig. 1, a prevent to scurry mould of activity on axle sleeve, fix bush 2 on die holder 1, it is connected with axle sleeve 3 to rotate on bush 2's the inner wall, the top fixedly connected with die 4 of axle sleeve 3, die 4 is used for stamping forming motor 11 iron core piece, the one end circumference spacing connection that die 4 was kept away from to axle sleeve 3 has worm wheel 5, worm wheel 5 is connected with the transmission of worm 6, worm 6 and motor 11 fixed connection, the inner wall of worm wheel 5 carries out circumference spacing connection through the key with axle sleeve 3, and the key is conventional technical structure, the tip fixedly connected with retaining ring 7 of die 4 is kept away from to axle sleeve 3, retaining ring 7 is used for preventing worm wheel 5 from breaking away from, the one end that retaining ring 7 was kept away from to worm wheel 5 offsets with bush 2, the one end that worm wheel 5 was kept away from to bush 2 is equipped with spacing groove 2.1, be equipped with the spacing step 3.1 that offsets with axle sleeve 3 on the axle sleeve 3.

Be equipped with retaining ring 7 in the one end of axle sleeve 3, and retaining ring 7 is used for spacing worm wheel 5, and guarantee the connection structure who offsets between worm wheel 5 and the bush 2, it is spacing to have realized the ascending removal of lower extreme of axle sleeve 3, and through the offset of spacing groove 2.1 and spacing step 3.1, it is spacing to have realized the decurrent removal in upper end of axle sleeve 3, thereby it is spacing to have realized the axial of axle sleeve 3, the axial removal has been avoided, and add bearing again between axle sleeve 3 and bush 2, can guarantee the pivoted smooth and easy nature between axle sleeve 3 and the bush 2.

As shown in fig. 1-2, be equipped with gasket 8 between bush 2 and the worm wheel 5, be equipped with six springs 9 between gasket 8 and the retaining ring 7, springs 9 are in compression state, six springs 9 evenly set up along the circumference of retaining ring 7, be equipped with the spring hole 5.1 that supplies spring 9 to pass on the worm wheel 5, be equipped with dowel 10 between worm wheel 5 and the gasket 8, dowel 10 is used for making fixed worm wheel 5 and gasket 8 carry out circumference spacing connection.

Because there is the region of offsetting between axle sleeve 3 and the bush 2, but both are the relation of relative rotation again, just cause the wearing and tearing that appear axle sleeve 3 or bush 2 in the rotation process easily, so increase the design of gasket 8, when wearing and tearing, wear and tear to gasket 8 preferentially to the protection axle sleeve 3 and bush 2, its easy maintenance, cheap.

However, after the gasket 8 is worn, the shaft sleeve 3 may move upwards, and a gap between the shaft sleeve 3 and the bushing 2 is generated, so that the position accuracy of the female die 4 is affected, and the quality problem of the iron core sheet of the stamping motor 11 is caused, and the maximum distance between the gasket 8 and the retainer ring 7 can be always maintained through the design of the spring 9 and the limiting design of the limiting groove 2.1 and the limiting step 3.1, after the gasket 8 is worn, the limiting groove 2.1 and the limiting step 3.1 are still guaranteed to abut against each other, the shaft sleeve 3 is prevented from moving upwards, the position of the female die 4 is guaranteed, and the spring 9 in the six circumferentially uniform arrays can guarantee the uniformity of the stress of the shaft sleeve 3, and the deflection of the stress of the shaft sleeve 3 is avoided.

The design of dowel 10 is in order to guarantee 8 and worm wheel 5's synchronous rotations of gasket, because do not carry out the synchronous rotation in-process between gasket 8 and the worm wheel 5, drive worm wheel 5 rotates the back, gasket 8 just rotates under the effort of spring 9, spring 9 atress is along spring 9's radial this moment, very easily cause the transformation of deformation and elastic force direction to spring 9, the life who causes spring 9 easily descends by a wide margin, be unfavorable for spring 9's life, and dowel 10's use only need on worm wheel 5 and gasket 8 process corresponding dowel hole 5.2 can, then the both ends of dowel 10 insert respectively worm wheel 5, in the dowel hole 5.2 of gasket 8.

Finally, the long-term use quality of the shaft sleeve 3 in the rotating use process is guaranteed, the stability of the female die 4 is guaranteed, and the chute has better consistency in the machining process.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. The present invention is not limited to the above embodiments, and the specific structure thereof is allowed to be changed. All changes which come within the scope of the invention as defined by the independent claims are to be embraced within their scope.
