Abstract
The invention discloses a lathe fixture for one-step clamping machining. Clamping error exists as twice clamping is usually necessary when parts with two end faces, an outer cylindrical surface and an inner hole needing to machine. The lathe fixture for one-step clamping machining comprises an elastic foundation body and an internal expanding cone, wherein the elastic foundation body comprises a mounting base and multiple elastic sheets, all of which are molded integrally; multiple mounting holes are formed in the mounting base; a main shaft positioning hole and a pull rod stretching-in hole are sequentially formed along the axial direction of the center of the mounting base; the main shaft positioning hole is a tapered hole; a small-diameter end is communicated with the pull rod stretching-in hole; multiple elastic sheets are distributed uniformly along the circumference and encircle to form an internal expanding cone mounting hole; the head part of the internal expanding cone mounting hole is a tapered hole while the tail part thereof is a cylindrical hole; the tail part of the cylindrical hole is communicated with the head part of the pull rod stretching-in hole; the internal expanding cone internally sleeves the internal expanding cone mounting hole of the elastic foundation body, and a connecting hole is formed along the axial direction of the center. The lathe fixture for one-step clamping machining can machine two end faces, the outer cylindrical surface and the inner hole through one-step clamping machining on the part, and can remove an error caused by twice clamping.
Description
Technical field
The invention belongs to mechanical manufacturing field, relate to a kind of fixture, be specifically related to a kind of turning attachment of clamped one time processing.
Background technology
Need to process the part of both ends of the surface, periphery and endoporus for one, conventionally all need twice clamping, first use the black skin clamping of part, process one of them end face and endoporus, then unload part, then the end face and the endoporus that go to location to process with another fixture.But the part of twice clamping exists clamping error, require the high part scrappage will be higher for axiality, and need two chassis beds just can complete operation.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of turning attachment of clamped one time processing is provided, part is carried out to clamped one time and just can complete both ends of the surface, periphery and endoporus processing, eliminate clamping error twice, save the lay day.
The present invention includes elastic foundation body and internal expanding cone.
Described elastic foundation body comprises integrated mount pad and multi-disc flexure strip; Described mount pad offers the multiple installing holes that are uniformly distributed along the circumference, and offers successively vertically main shaft orientation hole and pull bar in center and stretch into hole; Described main shaft orientation hole is bellmouth, and miner diameter end stretches into hole with pull bar and communicates, and the aperture of miner diameter end is greater than pull bar and stretches into the aperture in hole; Described multi-disc flexure strip is uniformly distributed along the circumference, and is encircled into internal expanding cone installing hole; The head of described internal expanding cone installing hole is bellmouth, and afterbody is cylindrical hole, and cylindrical hole and pull bar stretch into hole and coaxially arrange, and the afterbody of cylindrical hole is communicated with the head that pull bar stretches into hole.
Described internal expanding cone is nested with in the internal expanding cone installing hole of elastic foundation body, mate setting, and center offers connecting hole vertically with internal expanding cone installing hole.
Described multi-disc flexure strip, wherein the outer face of two flexure strips offers respectively an anti-rotation screwed hole.
Beneficial effect of the present invention:
The present invention carries out clamped one time to part just can complete both ends of the surface, periphery and endoporus processing, eliminates clamping error twice, saves the lay day, also saves and produces lathe.

Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of turning attachment of clamped one time processing comprises elastic foundation body 1 and internal expanding cone 2.
As shown in Fig. 3-1 and 3-2, elastic foundation body 1 comprises integrated mount pad 1-1 and 12 flexure strip 1-2; Mount pad 1-1 offers six installing hole 1-3 that are uniformly distributed along the circumference, and offers successively vertically main shaft orientation hole 1-4 and pull bar in center and stretch into hole 1-5; Main shaft orientation hole 1-4 is bellmouth, and miner diameter end stretches into hole 1-5 with pull bar and communicates, and the aperture of miner diameter end is greater than pull bar and stretches into the aperture of hole 1-5; 12 flexure strip 1-2 are uniformly distributed along the circumference, and are encircled into internal expanding cone installing hole 1-6, and wherein the outer face of two flexure strip 1-2 offers respectively an anti-rotation screwed hole 1-7; The head of internal expanding cone installing hole 1-6 is bellmouth, and afterbody is cylindrical hole, and cylindrical hole and pull bar stretch into hole 1-5 and coaxially arrange, and the afterbody of cylindrical hole is communicated with the head that pull bar stretches into hole 1-5.
As shown in Figure 4, internal expanding cone 2 is nested with in the internal expanding cone installing hole 1-6 of elastic foundation body, and 1-6 mates setting with internal expanding cone installing hole, and center offers connecting hole 2-1 vertically.
The turning attachment operation principle of this clamped one time processing:
Lathe spindle stretches in the main shaft orientation hole 1-4 of elastic foundation body, and elastic foundation body 1 is located by main shaft orientation hole 1-4 and end face, and fixes by screw and lathe spindle at each installing hole 1-3 place.In the tapping hole, axle center place of lathe pull bar, internal expanding cone 2 is fixing by the pull bar 3 of screw and lathe.Part 4 is nested with outside the flexure strip 1-2 of elastic foundation body, and fixing by screw and part 4 at anti-rotation screwed hole 1-7 place, prevent that part from adding revolution in man-hour.When the pull bar of lathe drives internal expanding cone 2 to move toward afterbody, internal expanding cone 2 struts each flexure strip 1-2 of elastic foundation body, thereby clamps part, and then with cutter, the both ends of the surface to part, periphery and endoporus are processed; When the pull bar of lathe drives internal expanding cone 2 to move toward head, flexure strip 1-2 sets back, thereby loosens the part machining.
