Abstract
The utility model discloses a high precision positioning claw. The claw is shaped like three steps, wherein the clamping surface of the claw is an arc surface which sticks to the surface of a workpiece to be machined; the bottom surface of the claw is a plane and fits with the chuck of the lathe spindle; the claw is provided with an inner counter bore; and the claw is connected with the chuck of the lathe spindle through a screw which fits with the inner counter bore. Sticking working surface of the arc surface of the claw and the surface of the lathe spindle chuck is in a vertical state; and the main axis of the clamped workpiece coincides with the spindle base line of the lathe chuck, namely the spindle base line of the machined workpiece is perpendicular to the direction of the machining movement. By adopting the utility model, the verticality and circular runout of the machined workpiece can be effectively ensured.
Description
Technical field
The utility model relates to a kind of claw, particularly a kind of hi-Fix claw.
Background technology
In the machining, especially fine finishining shaft element or cylindrical work require very high to its axiality (also can become circle beats).
Be processed as example with turning.Usually, by turnery (for example: axle), process the location by the clamping of lathe spindle chuck.Specifically as shown in Figure 1.
There is a shortcoming in this direct clamping in the locate mode of lathe spindle: because therefore non-applying of lathe chuck and contacting of workpiece to be machined cannot say for sure that main shaft baseline and the machine direction demonstrate,proved by the clamping body are in plumbness.In twice clamping process, also can not guarantee that work piece is in same center.Therefore, if workpiece directly is clipped on the scroll chuck of lathe, will certainly influence the axiality (far beating) of workpiece to be machined.Therefore when axle class that is processed with the degree of precision requirement or columniform nose circle face, perpendicularity, axiality (circle is beated) often can not get guaranteeing.Even if on some higher multifunction machine of precision also is like this.
By changing spindle chuck, increase on the spindle chuck claw with by the contact area of clamping body, make clamping firm.Work piece is steady when guaranteeing to cut, and helps high accuracy and forms.But this mode, cost are very high.Whether the new chuck of changing also is a pipe uncertain factor with addition of construction equipment main shaft size files.Whole reform technology complexity involves a wide range of knowledge.
The problem that prior art exists: because therefore non-applying of lathe chuck and contacting of workpiece to be machined cannot say for sure that main shaft baseline and the machine direction demonstrate,proved by the clamping body are in plumbness.In twice clamping process, also can not guarantee that work piece is in same center.Therefore, if workpiece directly is clipped on the scroll chuck of lathe, will certainly influence the axiality (far beating) of workpiece to be machined.Therefore when axle class that is processed with the degree of precision requirement or columniform nose circle face, perpendicularity, axiality (circle is beated) often can not get guaranteeing.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of hi-Fix claw is provided, the subsides and the face on claw and workpiece to be machined surface are fitted fully, assurance is in plumbness by the main shaft baseline and the machine direction of clamping body, promptly guarantees to add the perpendicularity and the axiality in man-hour.
In order to reach above-mentioned effect, the technical solution adopted in the utility model is as follows:
A kind of hi-Fix claw, described claw be three grades step-like, the clamping face of described claw is the arc surface of fitting with the workpiece to be machined surface, the bottom surface of described claw is the plane, and match with the lathe spindle chuck, offer counterbore on the described claw, described claw joins by screw and the lathe spindle chuck that matches with described interior counterbore.
Further, the clamping size files of the clamping face of described claw is than the big 0.05～0.10mm of processed axle external diameter.
Further, the diameter of counterbore is than the big 1～2mm of external diameter of described screw upper cap nut on the described interior counterbore, and the diameter of through hole is than the big 1～2mm of described screw external screw thread on the described interior counterbore.
The technique effect that described technical scheme reaches is as follows: this hi-Fix claw makes by the main shaft of clamping workpiece and overlaps with lathe chuck main shaft baseline, and promptly the main shaft baseline of processing work and working motion direction are perpendicular.The perpendicularity, the circle that guarantee workpiece to be machined are effectively beated.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is existing lathe spindle chuck clamping location front schematic view.
Fig. 2 is special claw front view.
Fig. 3 looks cutaway view for a special claw left side.
Fig. 4 locatees positive schematic diagram for hi-Fix claw clamping.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 3, claw 100 profiles and lathe spindle claw that the utility model provides are similar, and it is specially three grades ledge structure.
The utility model is designed to the plane with claw 100 bottom surfaces 102, and matches with the lathe spindle chuck; Clamping face 101 with claw 100 is designed to and the surperficial arc surface (as shown in Figure 2) of fitting of workpiece to be machined simultaneously.The perpendicularity, the circle that guarantee workpiece to be machined are effectively beated.
For realizing that claw 100 and lathe spindle chuck join, the utility model offers in one counterbore 200(as shown in Figure 3 on the intermediate step of claw 100), this claw 100 connects, is fixed in claw 100 internal threads on the lathe spindle chuck by the screw thread that matches with interior counterbore 200.
The diameter of the counterbore 201 in being somebody's turn to do on the counterbore 200 is than the big 1～2mm of external diameter of screw upper cap nut, and through hole 202 diameters on the interior counterbore 200 are than the big 1～2mm of screw external screw thread.
Before the each use of the utility model, earlier claw 100 is screwed on the lathe spindle chuck.Lathe tool according to the turning of processed axle outside dimension, makes it the clamping size files than the big 0.05～0.10mm of processed axle external diameter to clamping face 101, the binding face that makes claw 100 with fitted but not lathe chuck partial face contact by the nose circle face of the workpiece of clamping.
As shown in Figure 4, at this moment working face 102 faces of the clamping face 101 of claw 100 and lathe spindle chuck surface in vertical state, overlapped with lathe chuck main shaft baseline by the main shaft of clamping workpiece 300, promptly the main shaft baseline of processing work and working motion direction are perpendicular.The perpendicularity, the circle that guarantee workpiece to be machined are effectively beated.
No matter this type claw installs still dismounting, all locatees by screw and lathe spindle chuck.The claw process structure is simple, and processability is good.Selected material LY12 belongs to light material, sticking cutter can not take place in the cutting, collapse the cutter phenomenon.Have very high intensity and good cutting self lubricity, the comprehensive process performance is good.Not only easy to loading and unloading, laborsaving, whole with changing also shortening greatly of time, efficient and reliability height.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
