Abstract
The invention discloses an external grinding tool for a thin-walled cylindrical part and belongs to the field of precise machining. According to the external grinding tool, the thin-walled cylindrical part is clamped in the clamping modes of end face positioning and axial tensioning when the thin-walled cylindrical part is ground. The grinding tool comprises a mandrel (1) with threads, fastening screws (2), the ground part (3), a base plate (4) and a compression nut (5). The external grinding tool for the thin-walled cylindrical part is simple in structure and convenient to operate; radial clamping force can be prevented from being generated when the thin-walled cylindrical part is ground, and the problem that the precise grinding precision of the thin-walled cylindrical part is affected due to deformation of the part caused by radial clamping force is effectively solved.
Description
Technical field
The invention belongs to precision optical machinery manufacture field, be specifically related to a kind of cylindricalo grinding frock of thin wall cylinder part.
Background technology
The accurate grinding problem of thin cylinder part receives the concern of precision optical machinery field colleague always.In mechanical processing process, the uneven plastic deformation that the external force that is installed causes produces accessory size and the overproof main cause of the accuracy of form and position.
Chucking method during grinding part is a lot, and modal is the mode adopting scroll chuck to be installed, and now part is by radial load effect, firmly excessive during clamping, cause part ovalize or more serious situation to be polygon, hold not tight, likely make loose-parts when turning and scrap.Another kind of mode is by grinding inner bore of part match grinding mandrel, then the mode that is installed top on mandrel is withstood by grinding machine is top, this kind of mode is applicable to the accurate grinding of the stronger part of self rigidity, for thin cylinder part, because match grinding mandrel can produce radial load, cause part, when non-grinding, certain distortion just occurs, for the cylindricalo grinding of high-precision part, this method is also inapplicable.
For the feature of self poor rigidity of thin cylinder part, during particularly grinding high accuracy precision component, the mode that is installed during grinding is the key factor of restriction accessory size and the accuracy of form and position always, grinding mandrel is changed through a lot, such as: reduce coordinating tapering, changing on mandrel the center hole degree of depth etc. of grinding inner bore of part and mandrel, all fundamentally solution radial direction power that is installed impact that thin-walled parts is out of shape.
Summary of the invention
The technical problem to be solved in the present invention is: for the feature of self poor rigidity of thin cylinder part, proposes a kind of cylindricalo grinding frock of thin wall cylinder part.
The technical solution used in the present invention is: a kind of cylindricalo grinding frock of thin wall cylinder part, and this frock comprises threaded mandrel, clamp-screw, grinding part, backing plate and clamp nut; The using method of this frock is:
1), by top for grinding machine to withstand threaded mandrel two ends top, grinding A face, B face, when A face and grinding part, and the plane of threaded mandrel and grinding feature contacts, when B face and grinding part, the cylindrical that threaded mandrel coordinates with grinding part;
2), by grinding part tape loaded threaded mandrel, tighten up with clamp-screw, before tightening up, first empty handle, tightens up after cylindrical grinding until centering on lathe;
3), load onto backing plate, and tighten with clamp nut.
Wherein, grinding part is fixed on threaded mandrel by clamp-screw; The other end is by backing plate and clamp nut compacting grinding part.
Wherein, be matched in clearance in diametric(al) between threaded mandrel and grinding part, when grinding part, grinding machine is top, and to withstand threaded mandrel two ends top, with amesdial centering grinding part outer, fixed by clamp-screw, finally by clamp nut by backing plate compacting on grinding part.
Wherein, surface figure accuracy between threaded mandrel, grinding part, backing plate, clamp nut contact surface is according to different grinding element precision indexs, and can correspondingly improve, surface figure accuracy is higher, the radial direction power that is installed produced is less, and the precision index of grinding part is easier close to machine tool precision.
The present invention's advantage is compared with prior art:
(1) the threaded mandrel 1, in the present invention, only needs to be ground to matched in clearance with during grinding part 3 match grinding, does not need strict taper fit, fundamentally stops radial direction and to be installed power;
(2) mating surface between the threaded mandrel 1, in the present invention, clamp-screw 2, grinding part 3, backing plate 4, clamp nut 5 is the contact in face and face entirely, fundamentally stops radial direction and to be installed power;
(3), in the present invention, in order to tackle the impact brought at the radial grinding force of grinding stage generation, the generation of corresponding radial-thrust force respectively contacts a friction for normal pressure generation by grinding fixture, instead of pure radial direction is installed power, the size of frictional force regulates by the screw thread of clamp nut 5 with threaded mandrel 1.

Fig. 2 is the left TV structure schematic diagram of cylindricalo grinding frock main body of thin wall cylinder part of the present invention.
Detailed description of the invention
The present invention is further illustrated below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1 to Figure 2, the cylindricalo grinding frock of a kind of thin wall cylinder part of the present invention, comprising: threaded mandrel 1, clamp-screw 2, grinding part 3, backing plate 4, clamp nut 5, and its specific implementation method is as follows:
1), first by top for grinding machine to withstand threaded mandrel 1 two ends top, grinding A face, B face;
2), by grinding part 3 tape loaded threaded mandrel 1, tighten up with clamp-screw 2, before tightening up, first empty handle, tightens up after cylindrical grinding until centering on lathe;
3), load onto backing plate 4, and tighten with clamp nut 5.
Frock practical application: a collection of outside diameter is 120mm, diameter of bore is 108mm, and length is the part of 150mm, size 150 end flat degree, the depth of parallelism require 0.001mm, cylindrical 120 requires to join work with brearing bore, and interference requires 0.003mm to 0.006mm, cylindricity 0.003mm.After utilizing this frock, size and the accuracy of form and position all reach drawing requirement.
Non-elaborated part of the present invention belongs to techniques well known.
The above; be only part detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, any those skilled in the art are in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.
