Description
Technical field
The utility model belongs to machining equipment technology field, is specifically related to a kind of frock clamp of anti-machining deformation.
Background technology
In prior art, the frock clamp that roughing is used is single cone inner support fixture, its inside is bullet, tapered sleeve integral body is 5 valve structures, frock easily causes product gross distortion because cooperation place is whole for taper surface causes workpiece two ends discontinuity in clamping process, even produces the phenomenon such as burst apart in the time of seriously, caused waste to a certain degree, thereby be badly in need of improving.
Summary of the invention
The utility model object is to provide a kind of frock clamp of anti-machining deformation, and this fixture can make in frock clamping process stressed even, thereby reduces the generation of frock damage phenomenon in process.
Technical solution adopted in the utility model is as follows.
A frock clamp for anti-machining deformation, this instrument comprises cone, key, tapered sleeve, addendum cone head, nut, pull bar;
Wherein tapered sleeve is located between addendum cone head and cone; Tapered sleeve and cone cooperation place end face are that taper surface, tapered sleeve and addendum cone head cooperation place end face are taper surface;
The elongated end of cone in tapered sleeve is cylinder, and addendum cone head is located and is connected with centrum by pull bar by the cylinder of cone elongated end;
Key is located in the keyway in cone, is positioned at cone and tapered sleeve cooperation place;
Pull bar passes the hole at cone center, and extends through and expose from addendum cone head, and bared end and nut are fixed.
The frock clamp of described anti-machining deformation, tapered sleeve two ends are zigzag, can effectively prevent that blank inwall due to casting from having clamping that the residues such as splashings, scum cause and the distortion in process.
The frock clamp of described anti-machining deformation, tapered sleeve mid diameter is than the little 4mm of two ends diameter, can effectively prevent that blank inwall due to casting from having clamping that the residues such as splashings, scum cause and the distortion in process.
The frock clamp of described anti-machining deformation, uniformly on the outer wall of tapered sleeve middle part has three U-shaped grooves, inwall residue, iron filings etc. can be clamp-oned in this U-shaped groove, prevents clamping that inwall residue causes and the distortion in process.
The frock clamp of described anti-machining deformation, is provided with packing ring between nut and addendum cone head.
During concrete use, cone is connected with lathe, and tapered sleeve is contained in cone, and tapered sleeve one end coordinates with cone middle part taper surface, and the other end coordinates with addendum cone head taper surface.Tapered sleeve rotates with cone under the drive of key.Pull bar passes the hole at cone center, and is connected with oil cylinder by screw thread, and addendum cone head, packing ring, nut coordinate with pull bar, make tapered sleeve in cone, realize axial rotation under the drive of oil cylinder, and is longitudinally producing distortion, thereby realizes the clamping of workpiece.
The frock clamp of anti-machining deformation provided by the utility model, cone matches with inclined-plane, tapered sleeve inwall two ends, when clamping, two ends are simultaneously stressed, stressed in the same size, can effectively prevent the distortion in frock clamping and process, thereby significantly reduce percent defective, thereby there is good application value.
Accompanying drawing explanation
Fig. 1 is the frock clamp structural representation of anti-machining deformation provided by the utility model;
Fig. 2 is the tapered sleeve structural representation in the frock clamp of anti-machining deformation provided by the utility model, and wherein A is the rip cutting cross-sectional view of tapered sleeve, and B is the plan structure schematic diagram of tapered sleeve.
The specific embodiment
Below in conjunction with embodiment, the application is further explained to explanation.
Embodiment
As shown in Figure 1 and Figure 2, the frock clamp of anti-machining deformation provided by the utility model, comprises cone 1, key 2, tapered sleeve 3, addendum cone head 4, nut 6, pull bar 5;
Wherein tapered sleeve 3 is located between addendum cone head 4 and cone 1; Tapered sleeve 3 is taper surface with cone 1 cooperation place end face, and tapered sleeve 3 is taper surface with addendum cone head 4 cooperation place end faces;
The elongated end of cone 1 in tapered sleeve 3 is cylinder, and addendum cone head 4 is located and passed through pull bar 5 by the cylinder of cone 1 elongated end and is connected with centrum 1;
Key 2 is located in the keyway in cone 1, is positioned at cone 1 and tapered sleeve 3 cooperation places;
Pull bar 5 passes the hole at cone 1 center, and extends through and expose from addendum cone head 4, and bared end and nut 6 are fixing.
Tapered sleeve 3 two ends are zigzag, can effectively prevent that blank inwall due to casting from having clamping that the residues such as splashings, scum cause and the distortion in process.
Tapered sleeve 3 mid diameters are than the little 4mm of two ends diameter, can effectively prevent that blank inwall due to casting from having clamping that the residues such as splashings, scum cause and the distortion in process.
Uniformly on tapered sleeve 3 middle part outer walls have three U-shaped grooves, inwall residue, iron filings etc. can be clamp-oned in this U-shaped groove, prevent clamping that inwall residue causes and the distortion in process;
Between nut 6 and addendum cone head 4, be provided with packing ring 7.
During concrete use, cone 1 is connected with lathe by bolt, and key 2 is contained in the keyway in cone 1, and tapered sleeve 3 is contained in cone 1, and tapered sleeve 3 one end coordinate with cone 1 middle part taper surface, and the other end coordinates with addendum cone head 4 taper surfaces.Tapered sleeve 3 rotates with cone 1 under the drive of key 2.Pull bar 5 passes the hole at cone 1 center, and is connected with oil cylinder by screw thread, and addendum cone head 4, packing ring 7, nut 6 coordinate with pull bar 5, make tapered sleeve 3 realize axial rotation under the drive of oil cylinder in cone 1, and is longitudinally producing distortion, thereby realizes the clamping of workpiece.
The frock clamp of anti-machining deformation provided by the utility model, compared to existing frock clamp, because cone coordinates closely with inclined-plane, tapered sleeve inwall two ends, when clamping, two ends are simultaneously stressed, stressed in the same size, can effectively prevent the distortion in frock clamping and process, thereby significantly reduce percent defective, thereby there is good application value.
