Abstract

The utility model discloses an expansion sleeve gear-grinding core shaft. The expansion sleeve gear-grinding core shaft comprises a core shaft body, an expansion sleeve sleeving the outer conical surface of the core shaft body and a fastening nut in threaded connection with the left end portion of the core shaft body; the core shaft body is in threaded connection with an adjusting nut which is in contact with the right end of the expansion sleeve; the fastening nut acts on the left end of the expansion sleeve so that the right end of the expansion sleeve is propped against an end face of the adjusting nut. The expansion sleeve gear-grinding core shaft is capable of adjusting the expansion degree of the expansion sleeve and improving the universality of the expansion sleeve.

Description

A kind of ringfeder roll flute mandrel
Technical field
The utility model relates to a kind of fixture using in roll flute process, is specifically related to a kind of ringfeder roll flute mandrel.
Background technology
Adopt gear grinding machines to add man-hour to gear, because roll flute belongs to fine finishining, therefore in roll flute process, need to use gear grinding clamp accurately to locate gear.Traditional gear grinding clamp adopts clearance-type roll flute mandrel location, and the gap length of this locate mode can affect positioning precision, easily causes roll flute effect bad, can not meet technological requirement.
CN 2920501 Y disclose a kind of " clamping apparatus for gear wheel processing ", and it can reduce the required precision of the interior hole dimension to processed gear to a certain extent.But there are the following problems for it: (1) can not be adjusted the expansion-contraction degree of expansible mandrel (being equivalent to ringfeder), the expansion-contraction degree of expansible mandrel is limited, a fixture can only be used for locating a kind of gear that internal orifice dimension is identical, for internal orifice dimension different gears within the specific limits, need to use different fixtures, versatility is bad; (2) binding nut (being equivalent to clamp nut) clamps expansible mandrel by plain washer, easily produces radial load and make expansible mandrel unbalance stress in binding nut precession process, easily causes locating inaccurate; (3) expansible mandrel has annular groove on its external cylindrical surface, but its in compacted dilatancy process, be easily out of shape inhomogeneous, thereby cause positioning precision not high.
CN 201776530 U disclose a kind of " mandrel gear grinding clamp rises ", and it can avoid excesssive gap to bring error to a certain extent, can guarantee technological requirement.But there are the following problems for it: (1) can not be adjusted the expansion-contraction degree of ringfeder, the expansion-contraction degree of ringfeder is limited, and a fixture can only be used for locating a kind of gear that internal orifice dimension is identical, for internal orifice dimension different gears within the specific limits, need to use different fixtures, versatility is bad; (2) nut (being equivalent to clamp nut) compresses ringfeder by plain washer, easily produces radial load and make ringfeder unbalance stress in nut precession process, easily causes locating inaccurate.
Summary of the invention
The purpose of this utility model is to provide a kind of ringfeder roll flute mandrel, to adjust the expansion-contraction degree of ringfeder, improves versatility.
Ringfeder roll flute mandrel described in the utility model, comprise mandrel body, be enclosed within the ringfeder in the outer conical surface of mandrel body and be threaded connection the clamp nut in mandrel body left part, described mandrel body has been threaded connection an adjusting nut, this adjusting nut contacts with the right-hand member of ringfeder, described clamp nut acts on the left end of ringfeder, and the right-hand member of ringfeder is resisted against on the end face of adjusting nut.
Further, in order to convert the precessional motion of clamp nut to rectilinear motion, make ringfeder only be subject to axial compressive force, to prevent ringfeder discontinuity, on described mandrel body, be connected with a single direction thrust ball bearing, the left side of this single direction thrust ball bearing contacts with described clamp nut, and right side contacts with the left end step end face of described ringfeder, and described clamp nut acts on the left end step end face of ringfeder by single direction thrust ball bearing.
Further, in order to make ringfeder when compacted, evenly, to improve positioning precision, described ringfeder is made up of by 3~6 silica gel strips are bonding the identical ringfeder bulk-breaking of 3~6 lobes in distortion.After considering cost, technique, positioning precision, as preferably, described ringfeder is made up of by four silica gel strips are bonding the identical ringfeder bulk-breaking of pintongs.
When adjusting nut is during to right rotation certain distance, the outer conical surface of ringfeder relative mandrel body under the pressure-acting of clamp nut and the single direction thrust ball bearing certain distance of doing more physical exercises to the right, because mandrel body is outer conical surface herein, it is large that its extruding force to ringfeder becomes, thereby ringfeder degrees of expansion is increased, can locate the larger gear of internal orifice dimension; When adjusting nut is during to anticlockwise certain distance, the outer conical surface of ringfeder relative mandrel body under the pressure-acting of clamp nut and single direction thrust ball bearing is lacked motion certain distance to the right, because mandrel body is outer conical surface herein, its extruding force to ringfeder diminishes, thereby ringfeder degrees of expansion is reduced, can locate the smaller gear of internal orifice dimension.
The utility model, by connecting adjusting nut, coordinates the outer conical surface of clamp nut and mandrel body, can adjust the expansion-contraction degree of ringfeder, can locate internal orifice dimension different gears within the specific limits, and versatility is good; Clamp nut acts on ringfeder by single direction thrust ball bearing, and in clamp nut precession process, ringfeder is only subject to axial compressive force, and ringfeder is stressed evenly, accurate positioning; Ringfeder is made up of by 3~6 silica gel strips are bonding the identical ringfeder bulk-breaking of 3~6 lobes, and ringfeder is when compacted, and dilatancy is even, has improved positioning precision, can meet technological requirement.
Accompanying drawing explanation
Fig. 1 is left view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Ringfeder roll flute mandrel as shown in Figure 1, Figure 2, Figure 3 shows, comprise mandrel body 4, be enclosed within the ringfeder 5 in the outer conical surface of mandrel body 4 and be threaded connection the clamp nut 1 in mandrel body 4 left parts, ringfeder 5 is made up of by four silica gel strips 3 are bonding the identical ringfeder bulk-breaking 51 of pintongs.On mandrel body 4, be connected with a single direction thrust ball bearing 2, the left side of single direction thrust ball bearing 2 contacts with clamp nut 1, the right side of single direction thrust ball bearing 2 contacts with the left end step end face of ringfeder 5, mandrel body 4 has been threaded connection an adjusting nut 6, this adjusting nut 6 contacts with the right-hand member of ringfeder 5, clamp nut 1 acts on the left end step end face of ringfeder 5 by single direction thrust ball bearing 2, the right-hand member of ringfeder 5 is resisted against on the end face of adjusting nut 6.
