Abstract
The utility model discloses a machining tool for ultra thin-walled cylinder type workpieces. The machining tool comprises a supporting seat, a locating ring, an expansion sleeve, a connecting sleeve, a central spindle and a gland. A shaft ring is formed close to the left end of the central spindle, a stepped shaft is formed on the other side of the shaft ring, and an outer thread is formed on the small-diameter stepped shaft close to a shaft shoulder. The stepped end of the central spindle penetrates through a center hole of the connecting sleeve. A gasket and a nut are sequentially screwed into the outer thread of the central spindle in an assembling groove, the central spindle is fixedly connected with the connecting sleeve, the expansion sleeve is mounted on the outer circle of the connecting sleeve, and the supporting seat abuts against the expansion sleeve through the locating ring. The left end of the tower-shaped gland abuts against the right end of the connecting sleeve. By means of the machining tool for the ultra thin-walled cylinder type workpieces, the problem that the ultra thin-walled cylinder type workpieces cannot be clamped is solved, meanwhile, workpiece deformation in the clamping and machining process can be avoided, the machining precision and the mounting and dismounting efficiency are improved, and an effective solution is provided for batch machining of the ultra thin-walled cylinder type workpieces.
Description
Technical field
The utility model belongs to a kind of harness of workpiece processing, is specifically related to a kind of processing harness of ultra-thin-wall cylinder class workpiece.
Background technology
Ultra-thin-wall tube kind part is because its wall is thin; under nature, conventionally can be irregular ellipticity; therefore in ultra-thin-wall tube kind part machining; the positioning and clamping difficulty for the treatment of processing parts is very large; in some cases, need to will process thickness to the periphery of this kind of ultra-thin-wall cylinder class part only has the endless belt that hairline is thick, causes requirement positioning accuracy request high because wall is thin; otherwise in processing, workpiece is very easily damaged, guarantee that machining accuracy difficulty is larger.
At present, be directed to the processing of ultra-thin-wall tube kind part, field of machining or a great difficult problem.
Summary of the invention
The utility model proposes for solving the problem of prior art existence, its objective is the processing harness that a kind of ultra-thin-wall cylinder class workpiece is provided.
The technical solution of the utility model is: a kind of processing harness of ultra-thin-wall cylinder class workpiece, comprise supporting base, locating ring, expansion sleeve, adapter sleeve, mandrel and gland, in the left part near mandrel, form the axle collar, opposite side at the axle collar forms multidiameter, on the minor diameter multidiameter near shaft shoulder place, is formed with external screw thread.The stepped end of mandrel, through the centre bore of adapter sleeve, is screwed into pad, nut successively the external screw thread place of mandrel in assembling groove, and mandrel and adapter sleeve are fixed, and expansion sleeve is arranged on the cylindrical place of adapter sleeve, and supporting base holds out against expansion sleeve by locating ring.The left end of turriform gland holds out against the right-hand member of adapter sleeve.
Described expansion sleeve is the cylinder that internal diameter has tapering, and the tapering of internal diameter is 1:20～30.
Described adapter sleeve is the cylinder that external diameter has tapering, and the tapering of external diameter is 1:20～30.
The utility model has solved the problem that ultra-thin-wall cylinder class workpiece cannot clamping, also avoided workpiece in clamping and process to deform simultaneously, machining accuracy and the efficiency of loading and unloading have been improved, for the processing of ultra-thin-wall cylinder class batch workpieceization provides effective solution.

The specific embodiment
Below, with reference to drawings and Examples, the utility model is elaborated:
As shown in Figure 1, a kind of processing harness of ultra-thin-wall cylinder class workpiece, comprise supporting base 1, locating ring 2, expansion sleeve 3, adapter sleeve 5, mandrel 6 and gland 9, mandrel 6 both ends of the surface form installs with centre bore 10, in the left part near mandrel 6, form the axle collar 11, opposite side at the axle collar 11 forms multidiameter, on the minor diameter multidiameter near shaft shoulder place, be formed with external screw thread 12, the stepped end of mandrel 6 is through the centre bore of adapter sleeve 5, successively by being screwed into pad 7, nut 8 and being screwed into external screw thread 12 places of mandrel 6, mandrel 6 and adapter sleeve 5 is fixing in assembling groove 13.
As shown in Figure 2,3, expansion sleeve 3 has the cylinder of tapering for internal diameter, and the tapering of internal diameter is 1:20～30, and adapter sleeve 5 has the cylinder of tapering for external diameter, and the tapering of external diameter is 1:20～30, at the left end of adapter sleeve 5, forms assembling groove 13.
Expansion sleeve 3 is arranged on the cylindrical place of adapter sleeve 5, and supporting base 1 holds out against expansion sleeve 3 by locating ring 2.The left end of turriform gland 9 holds out against the right-hand member of adapter sleeve 5.
The centre bore 10 at mandrel 6 two ends is processed into High Precision Central hole, to guarantee workpiece to be processed 4 and mandrel 6 high-precision coaxial degree requirements.
Installation process of the present utility model:
Locating ring 2 is placed on supporting base 1, workpiece to be processed 4 is placed on outside locating ring 2, axial location for workpiece to be processed 4, expansion sleeve 3 is placed in workpiece to be processed 4, the adapter sleeve 5 that fixes mandrel 6 is placed in expansion set 3, the male cone (strobilus masculinus) of adapter sleeve 5 agrees with mutually with the inner conical surface of expansion sleeve 3, described workpiece to be processed 4 and adapter sleeve 5 matched in clearance, with 9 pairs of adapter sleeves 5 of turriform gland, apply external force, adapter sleeve 5 is moved left vertically, because expansion sleeve 3 is monolithic construction, expansion sleeve 3 is slot-less full circle face with the contact-making surface of workpiece to be processed 4, expansion sleeve 3 cylindricals are increased, thereby by the swollen circle of workpiece to be processed 4 swelling.
The utility model has solved the problem that ultra-thin-wall cylinder class workpiece cannot clamping, also avoided workpiece in clamping and process to deform simultaneously, machining accuracy and the efficiency of loading and unloading have been improved, for the processing of ultra-thin-wall cylinder class batch workpieceization provides effective solution.
