Abstract
The utility model relates to a kind of thin-wall part cutting antihunting protection; comprise positioning seat, clamping screw, briquetting; described positioning seat is fixed on part; on positioning seat, by screw thread, be provided with several circumferentially uniform clamping screws; clamping screw one end is provided with winding device, and the other end is pressed on the external diameter of inner diameter location to be processed on part by briquetting.The utility model adds man-hour in the thin-walled portion of part, plays good location, centering effect, and can prevent that part from trembling and being out of shape, have simultaneously lightweight, simple to operate, applied range, the high and advantage of injuring part not of dependability.
Description
Technical field
The utility model relates to a kind of protective device, especially a kind of thin-wall part cutting antihunting protection.
Background technology
In mechanical processing process, often run into thin wall component, wall thickness only has 1～3 millimeter.Especially for larger thin-wall part, under cutting tool effect, can tremble, be out of shape, if do not take external force to assist safeguard procedures, be difficult to process qualified products.For thin wall cylinder class part, in processing, often adopt during external diameter the internal expansion type spring piece that rises that thin wall cylinder inwall is propped up, prevent that thin wall cylinder is out of shape under cutter active force; When processing endoporus, should take effective auxiliary support apparatus to hold tightly to the part application of force from thin wall cylinder outer wall, the effect of opposing Tool in Cutting power.At machine, add in process, conventionally adopt self-control simple frock: according to machine-made spares external shape, manufacture a rigidity outer shroud, external annulus is installed housing screw, by screwing screw, steel loop and part hoop is integral, and plays reinforcement External Force Acting.This constructional device one is heavier, and to part, handling bring constant; The 2nd, with part, accurately do not locate, cause occurring deflection or loosening in part processing rotary course, there is potential safety hazard, can not meet again and control part deformation instructions for use.
Summary of the invention
The purpose of this utility model is to provide a kind of thin-wall part machining servicing unit: when this device is mainly used in thin-wall part processing endoporus (or internal structure), supplemental support external force is provided, have simple and light, prevent that part from trembling and the feature of distortion and good reliability.
Concrete technical scheme of the present utility model is; thin-wall part cutting antihunting protection comprises positioning seat, clamping screw, briquetting; described positioning seat is fixed on part; on positioning seat, by screw thread, be provided with several circumferentially uniform clamping screws; clamping screw one end is provided with winding device, and the other end is pressed on the external diameter of inner diameter location to be processed on part by briquetting.Described positioning seat is light material, in the position that clamping screw is installed, is provided with steel screw bushing, and steel screw bushing is located by holding screw, and clamping screw is provided with on steel screw bushing.The material of described positioning seat is aluminium, and the material of described briquetting is nylon.Described positioning seat is fixed on part by bolt, and the position that described bolt contacts with part is provided with locating piece, and the material of described locating piece is nylon.The position that described briquetting contacts with clamping screw is provided with groove, and clamping screw is pressed in groove.Described winding device is nut with holes.Locating surface on described positioning seat coordinates with plane and seam corresponding on part, plays the effect of centering, location.
As another kind of technical scheme of the present utility model, for having flange with holes on part, described clamping screw is fixed on the hole on the flange on part.
Positioning seat of the present utility model, as protective device main body, mainly plays two aspect effects: the one, be located by connecting with institute processing parts, and the 2nd, the controls of protective device is played to support and connection fixation.The structure of positioning seat can be according to part real space location positioning, if part has flange with holes, positioning seat can by bolt and part flange is lateral opening be connected and fixed; If part does not possess the structures such as hole, positioning seat correct position on part is fixedly held tightly.Screwing structure is to determine according to the special construction of protective device and part, and due to the restriction of Space configuration structure, when handling screwing mechanism, general spanner can use limited, so need to join, makes special spanner; For weight reduction, positioning seat adopts lightweight aluminium conventionally, but auxiliary force application structure adopts clamping screw to screw mode, and clamping screw repeatedly operation can cause aluminum positioning seat upper screwed hole screw thread damaged, therefore steel screw bushing is installed in positioning seat screwed hole position, is increased screw strength.In order to prevent that bolt from screwing in process, drive steel screw bushing to rotate, by holding screw, steel screw bushing is fixedly connected with positioning seat.Briquetting is the auxiliary spare part mainly contacting with part, apply external force and be delivered on part by briquetting, so the structural design of briquetting must to support outer wall shape and structure consistent with part, and take into full account part outer wall machine and add or cast profile, prevents briquetting interference.Considering that on the light basis of protective device structure, positioning seat adopts aluminium; For locating piece and the briquetting that prevents from contacting with part prevents from colliding with, scratching part, adopt the nonmetallic materials such as nylon 1010, this material flow performance is good, is conducive to apply external force and evenly transmits.The utility model is according to the design of part feature of processing; design a set of complete protective device; supplemental support external force can be provided, in the thin-walled portion of part, add man-hour, play good location, centering effect; and can prevent that part from trembling and being out of shape; have simultaneously lightweight, simple to operate, applied range; high and the advantage of injuring part not of dependability, has guaranteed the crudy of part thin-walled inner-diameter portion whose.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in the figure; thin-wall part cutting antihunting protection comprises positioning seat 1, clamping screw 3, briquetting 6; described positioning seat 1 is fixed on part 2; on positioning seat 1, by screw thread, be provided with several circumferentially uniform clamping screws 3; clamping screw 3 one end are provided with winding device, and the other end is pressed on the external diameter of inner diameter location to be processed on part 2 by briquetting 6.Described positioning seat 1 is light material, in the position that clamping screw 3 is installed, is provided with steel screw bushing 4, and steel screw bushing 4 is located by holding screw 5, and clamping screw 3 is provided with on steel screw bushing 4.The material of described positioning seat 1 is aluminium, and the material of described briquetting 6 is nylon.Described positioning seat 1 is fixed on part 2 by bolt 9, and the position that described bolt 9 contacts with part 2 is provided with locating piece 10, and the material of described locating piece 10 is nylon.Described briquetting 6 is provided with groove with the position that clamping screw 3 contacts, and clamping screw 3 is pressed in groove.Described winding device is nut with holes.Locating surface on described positioning seat 1 coordinates with plane and seam corresponding on part 2, plays the effect of centering, location.
