Description
Technical field
The utility model relates to machining application, and particularly a kind of lathe finishing of internal diameter uses the fixture being used for fixing thin slice or thin ring wall class workpiece.
Background technology
The finishing of internal diameter of thin slice thin ring wall class workpiece is generally process on numerically controlled lathe or engine lathe.Thin slice thin ring wall class workpiece has the feature of the wall thickness little (8 ~ 15mm) between thickness little (5 ~ 10mm), two rings, and the machining accuracy that its design feature determines its endoporus directly affects by installation way.In most cases, this kind of workpiece is generally that the cylindrical of direct clamping workpiece is processed, and the factor due to clamping force makes thin slice thin ring wall class workpiece deform on diameter and thickness direction, and its precision is difficult to be guaranteed.
Summary of the invention
The utility model is for above-mentioned technical problem, a kind of special structure is proposed, change its installation way, it is axial grip that thin slice or thin ring wall class workpiece are shifted by radial clamping, thin slice thin ring wall class diameter of work direction is not deformed, to ensure the thin slice thin annular workpieces finishing of internal diameter fixture of thin slice thin ring wall class inner hole of workpiece machining accuracy.
For reaching above object, be achieved through the following technical solutions:
A kind of thin slice thin annular workpieces finishing of internal diameter fixture, comprises, positioning base and gland;
Positioning base is provided with stepped groove;
Gland is assemblied in positioning base by bolt assembly and is provided with stepped groove end face;
Gland is processed with and stepped groove shape same via, and the hole size of gland is less than stepped groove maximum diameter of hole part;
Adopt the utility model of technique scheme, realize thin slice or thin annular workpieces and embed by arranging stepped groove at positioning base and be positioned on the ladder table top of stepped groove, then by installing the ladder table top that Work-sheet pressing is held on stepped groove by gland on the axial direction of stepped groove, axial compression is formed;
And thickness of workpiece can be greater than the ladder degree of depth of stepped groove and gland and positioning base stepped groove end face and has gap herein, namely gland and positioning base form the clamping with gap.
As preferably, positioning base comprises, internal thread outer sleeve and external screw thread inner core; Internal thread outer sleeve inwall front end is smooth surface; External screw thread inner tank theca front end is smooth surface; External screw thread inner core is threaded connection and is assemblied in internal thread outer sleeve inside, and external screw thread inner core front end outer wall and internal thread outer sleeve front inner wall form stepped groove inwall jointly;
Positioning base also comprises, and is nested with to be assemblied in external screw thread inner core and to stretch out in locking positioning ring in the thread surface of internal thread outer sleeve rear end;
Positioning base is divided into internal thread outer sleeve and external screw thread inner core Screw assembly by this structure, positioned by locking positioning ring internal threads outer sleeve again, and then external screw thread inner core front end outer wall and internal thread outer sleeve front inner wall form stepped groove inwall jointly, so form the step-thickness adjustable of a stepped groove, make thin slice that this device suitable thicknesses is different or thin annular workpieces.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of description, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

In figure: 1, positioning base, 1.1, stepped groove, 1.2, internal thread outer sleeve, 1.3, external screw thread inner core, 1.4, locking positioning ring, 2, gland, 3, bolt assembly.
Note: in accompanying drawing Fig. 2, two chain-dotted lines formation annulus represent processing work.
Detailed description of the invention
A kind of thin slice thin annular workpieces finishing of internal diameter fixture as depicted in figs. 1 and 2, comprises, positioning base 1 and gland 2;
Positioning base 1 is provided with stepped groove 1.1;
Gland 2 is assemblied in positioning base 1 by bolt assembly 3 and is provided with stepped groove 1.1 end face;
Gland 2 is processed with and stepped groove 1.1 shape same via, and the hole size of gland 2 is less than stepped groove 1.1 maximum diameter of hole part;
Adopt the utility model of technique scheme, realize thin slice or thin annular workpieces and embed by arranging stepped groove 1.1 at positioning base 1 and be positioned on the ladder table top of stepped groove 1.1, then by installing the ladder table top that Work-sheet pressing is held on stepped groove 1.1 by gland 2 on the axial direction of stepped groove 1.1, axial compression is formed;
And thickness of workpiece L3 can be greater than the ladder degree of depth L4 of stepped groove 1.1 and gland 2 has gap L 2 with positioning base 1 stepped groove 1.1 end face herein, namely gland 2 and positioning base 1 form the clamping with gap L 2.
As preferably, positioning base 1 comprises, internal thread outer sleeve 1.2 and external screw thread inner core 1.3; Internal thread outer sleeve 1.2 inwall front end is smooth surface; External screw thread inner core 1.3 outer wall front end is smooth surface; External screw thread inner core 1.3 is threaded connection and is assemblied in internal thread outer sleeve 1.2 inside, and external screw thread inner core 1.3 front end outer wall and internal thread outer sleeve 1.2 front inner wall form stepped groove 1.1 inwall jointly;
Positioning base 1 also comprises, and is nested with to be assemblied in external screw thread inner core 1.3 and to stretch out in locking positioning ring 1.4 in the thread surface of internal thread outer sleeve 1.2 rear end;
