The slot bottom facial contour of the workpiece pedestal mounting groove is polygon, preferably rectangle.
The slot bottom facial contour of the workpiece pedestal mounting groove, which preferably comprises, angularly positions straight flange at one.
The linear dimension of the groove bottom of the workpiece pedestal mounting groove is preferably according to the pedestal with the workpiece in respective party Upward unilateral fit tolerance is+0.02mm production.
The diameter of the positioning column is preferably+0.02mm production according to fit tolerance between the through-hole.
The shape of the pedestal is preferably in rotary structure.
The diameter on the top of the pedestal is typically larger than the lower part of the pedestal.
The depth of the workpiece pedestal mounting groove should be no more than the height of the pedestal of workpiece to be installed.
Further, the pin hole radially extended, installation condition are each provided on the workpiece mounting portion and clamping cap Under, a positioning pin is also cross the two pin holes on the workpiece mounting portion and clamping cap.
Gasket is also provided between the top surface of the workpiece and the head of screw of the screw.
The beneficial effects of the present invention are:
Using the present invention may be implemented lathe on workpiece do not have to carry out again it is traditional being straightened and adjusting back and forth, therefore can be obvious It saves manpower and saves working hour.
Since the present invention is equivalent to standard component, multiple workpiece may be implemented using unified coordinate system to process, therefore not Only the machining accuracy of single workpiece is high and reproducible with the precision between a batch of workpiece.
After applying the present invention, traditional that knife can be changed into fixture, therefore each workpiece can not had to primary Knife further saves working hour.
The configuration of the present invention is simple is small and exquisite, light, flexibly, is easy production, and can replace, the advantage when being used in batch production It is particularly evident.
The present invention cannot be only used for processing, and be also used in the measurement of some complex curved surface parts, once clamping is fixed, and it is fixed Position is reproducible, and the determination of measuring basis is simplified, therefore has also correspondinglyd increase measurement efficiency.
Detailed description of the invention
Fig. 1 is the explosive view of one embodiment of the present of invention.
Specific embodiment
The invention discloses a kind of frock clamps for being applicable in the batch production of high-precision small part, as shown in Figure 1, including chuck 1 and pedestal 2, the top of the pedestal is workpiece mounting portion 21, and the top surface of the workpiece mounting portion is equipped with the installation of workpiece pedestal Slot 211 is fixed with the positioning column 212 perpendicular to groove bottom, the height of positioning column in the groove bottom of the workpiece pedestal mounting groove Degree is lower than the height of workpiece.Under installation condition, the pedestal of workpiece is embedded in the workpiece pedestal mounting groove, and the positioning column passes through A through-hole on workpiece, and cooperate with the via clearance.The top of the positioning column is equipped with threaded hole, 3 screw thread of a screw It is connected in the threaded hole, the head of screw of the screw resists on the reserved positioning surface of the top surface of workpiece, by the workpiece pressure Tightly in the groove bottom of the workpiece pedestal mounting groove.The chuck is located at the lower part of the pedestal and its claw grips institute State the lower part 22 of pedestal.
The water of the pedestal (usually technique pedestal) of the slot bottom facial contour and workpiece to be mounted of the workpiece pedestal mounting groove Flat profile is consistent, generally polygon, and to prevent circumferentially rotating for workpiece, preferably rectangle, structure is simpler.
The slot bottom facial contour of the workpiece pedestal mounting groove is also possible to other shapes, such as round.Meanwhile the workpiece The slot bottom facial contour of pedestal mounting groove preferably comprises and angularly positions straight flange 213 at one, can prevent workpiece circumferential in process Play, processing may insure all to keep identical orientation angles to be mounted on fixture with a collection of workpiece before starting.
The linear dimension of the groove bottom of the workpiece pedestal mounting groove can according to the pedestal of workpiece to be installed corresponding Unilateral fit tolerance is+0.02mm production on direction.Certainly, it should specifically be determined with reference to the requirement on machining accuracy of workpiece.Workpiece Requirement on machining accuracy is higher, and the fit clearance between the workpiece pedestal mounting groove and the pedestal of workpiece answers smaller, and the work Assembly precision between part pedestal mounting groove and the pedestal of workpiece should at least be not less than the precision prescribed of workpiece.
The diameter of the positioning column is preferably+0.02mm production according to fit tolerance between the through-hole.
The shape of the pedestal is unlimited, simplifies for structure and needs, and is preferably in rotary structure, easy to process.
The lower part of the pedestal is mainly used for gripping for chuck, and size is unlimited.It is excellent in the embodiment shown in that figure The pedestal is arranged to up big and down small stepped shaft structure by choosing, i.e., the diameter on the top of the described pedestal is greater than under the pedestal Portion, chuck clamp when, claw is clamped on the outer cylinder of the lower part of the pedestal, the top surface of claw lean against the pedestal it is upper, On step surface between lower part.Certainly, the diameter of the lower part of the pedestal can also be greater than top, correspondingly, the pedestal The settable inner hole that Open Side Down in lower part can realize claw as positioning surface by the cylinder of inner hole and the inner end end face of inner hole Clamping.
The depth of the workpiece pedestal mounting groove should make the clamping cap will no more than the height of the pedestal of workpiece to be installed The pedestal of workpiece is firmly pressed in the workpiece pedestal mounting groove, to fix the workpiece in the height direction.
Gasket 4 is also provided between the top surface of the workpiece and the head of screw of the screw, in order to avoid the pressure of head of screw The top surface of defective work piece.
When installation, workpiece is passed through into the positioning column and is fitted into the workpiece pedestal mounting groove on the pedestal, at this time The top surface of the positioning column is not higher than the top surface of the workpiece, reserves positioning around the top of the especially not greater than described through-hole Then gasket is put on the top surface of workpiece in face, pass through gasket with screw and screw in the positioning column, until gasket is pressed on work On part top surface, the workpiece is pressed on the workpiece pedestal mounting groove at this time, completes workpiece determining in the height direction Position and clamping.
The present invention can be used for the batch production of high-precision, small part, help to significantly improve production efficiency and processing essence Degree.
