Background technology
At present using the direct clamping thin-walled parts of common scroll chuck or using the elastic jacket and thin-walled for opening three bar grooves Part together clamping on scroll chuck.The shortcomings that this structure, is:It is easily produced under the action of clamping force because part wall is thin Change shape, and a cylindrical hole is obtained after endoporus is ground on lathe, but unclamps after claw removes part and restore to become due to elastic Camber triangle, so as to which required machining accuracy be not achieved.
Invention content
The utility model is in view of the above-mentioned problems, provide a kind of numeral-controlled internal grinder thin-walled parts clamping mould, the clamping tire Tool can reduce thin-walled parts in process, and radial force is small, effectively reduce part deformation, improve processing quality.
According to the technical solution of the utility model:A kind of numeral-controlled internal grinder thin-walled parts clamping mould, it is characterised in that: Including power chuck, one side end face of power chuck is fixedly connected with disk, and terminal pad is fixedly connected with main shaft;Oil is set in inner hole of spindle Cylinder pull rod, oil cylinder pull rod are fastenedly connected with power chuck;Another side end face of power chuck is along the circumferential direction uniformly arranged three cards Disk claw, by three chuck jaws clampings, mould stretches into one end in chuck jaws and passes through the claw that is formed on chuck jaws mould Limiting section positions, and thin-walled parts installation station is formed on mould, it is thin that the threaded connection of mould outer circumference face is useful for positioning fixation The clamp nut of wall part.
As further improvement of the utility model, the endoporus of the mould includes the first hole set gradually from inside to outside Portion, the second hole portion, third hole portion, the 4th hole portion, the 5th hole portion.
As further improvement of the utility model, the endoporus of the power chuck is fixed with locating piece, oil cylinder pull rod with Locating piece is fixedly connected.
As further improvement of the utility model, root and the chuck jaws endoporus junction of the claw limiting section are set It is equipped with circular arc chamfering.
As further improvement of the utility model, the connecting portion of the main shaft is equipped in the endoporus of terminal pad, Using taper fit between terminal pad and main shaft connecting portion, fastened and connected by attachment screw between terminal pad and spindle flange face It connects.
The utility model has technical effect that:The utility model product structure is simple, compact, has processing and manufacturing cost It is relatively low and be easier to implement, the features such as performance is stablized again, precision is high, service life is long, it both ensure that high efficiency, in turn ensure high-precision Degree and flexibly multifunctionality.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the right view of Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1,2, including main shaft 1, terminal pad 2, oil cylinder pull rod 3, power chuck 4, mould 5, annular projection portion 5-1, One hole portion 5-2, the second hole portion 5-3, third hole portion 5-4, the 4th hole portion 5-5, the 5th hole portion 5-6, thin-walled parts 6, clamp nut 7th, chuck jaws 8, claw limiting section 8-1 etc..
As shown in Figure 1, 2, the utility model is a kind of numeral-controlled internal grinder thin-walled parts clamping mould, including power chuck 4,4 one side end face of power chuck is fixedly connected with disk 2, and terminal pad 2 is fixedly connected with main shaft 1;Oil cylinder pull rod is set in 1 endoporus of main shaft 3, oil cylinder pull rod 3 is fastenedly connected with power chuck 4;4 another side end face of power chuck is along the circumferential direction uniformly arranged three chucks Claw 8, for mould 5 by three 8 clampings of chuck jaws, mould 5 stretches into one end in chuck jaws 8 by being formed on chuck jaws 8 Claw limiting section 8-1 is positioned, and thin-walled parts 6 are formed on mould 5 and install station, 5 outer circumference face of mould is threadedly coupled and is useful for The clamp nut 7 of the fixed thin-walled parts 6 of positioning.The outer profile of clamp nut 7 is uniformly arranged gap slot.
The endoporus of mould 5 include set gradually from inside to outside the first hole portion 5-2, the second hole portion 5-3, third hole portion 5-4, 4th hole portion 5-5, the 5th hole portion 5-6.
The endoporus of power chuck 4 is fixed with locating piece, and oil cylinder pull rod 3 is fixedly connected with locating piece.
The root of claw limiting section 8-1 is provided with circular arc chamfering with 8 endoporus junction of chuck jaws.
The connecting portion of main shaft 1 is equipped in the endoporus of terminal pad 2, using cone between 1 connecting portion of terminal pad 2 and main shaft Degree coordinates, and is fastenedly connected between 1 flange face of terminal pad 2 and main shaft by attachment screw.
The course of work of the utility model is as follows:Power chuck 4 is connect by terminal pad 2 with workpiece transmission main shaft 1, main shaft 1 drives revolution by motor.Chuck jaws 8 are mounted on 4 outer end face of power chuck, and clamping and the release of chuck jaws 8 pass through oil cylinder Pull rod 3 moves left and right to realize.Chuck jaws 8 be installed in place after by the internal grinding head of lathe come autogenous grinding claw limiting section 8-1 End face and clamping Inner arc.Autogenous grinding can ensure that three chuck jaws 8 clamp arc surface with one heart so as to ensure mould 5 by chuck card Pawl 8 clamps securely.Two endoporus guide cylinder faces of mould 5 exist with the benchmark outer circle clearance control of thin-walled parts 6 to be processed Within 0.025-0.04mm, it should ensure that thin-walled parts 6 are convenient to mount and dismount, ensureing again cannot be too loose to influence part revolution at a high speed When it is eccentric.Thin-walled parts 6 screw clamp nut 7 after being packed into mould 5 so that the both sides of the face of thin-walled parts 6 are secured in a press.This The radial direction of sample thin-walled parts 6 in clamping and processing does not stress substantially, so as to effectively reduce the clamping and machining deformation of part.
The utility model product clamps mould using the soft claw of power chuck, does not clamp thin-walled parts directly, avoids part Pinching deformation;Claw autogenous grinding on lathe, it is concentric with main shaft to ensure;Mould is by nut compressing component end face with constant zero Part ensures that part does not stress radially.
