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 high-precision PETS parts and reflecting mirror parts batch production labor clamps, such as Fig. 1 institute
Show, including chuck 1, pedestal 2 and clamping cap 3, the top of the pedestal is workpiece mounting portion 21, the top surface of the workpiece mounting portion
It is equipped with workpiece base installing hole 211, the outer cylinder of the workpiece mounting portion is equipped with external screw thread.The clamping cap is equipped with interior
The cover shape of screw thread, the top surface of the clamping cap are equipped with upper and lower perforative through-hole 31.Under installation condition, the clamping cap is by upper
It is buckled in downwards on the workpiece mounting portion 21, inner side end is pressed on the top surface of workpiece, and clamping cap passes through its internal screw thread and institute
It states workpiece mounting portion and is threadedly coupled fixation.The profile of the through-hole is located at workpiece pedestal installation on same level perspective plane
Within the profile in hole or the two locally intersects, and the chuck is located at the lower part of the pedestal and its claw grips the base
The lower part 22 of seat.
Preferably, the center of workpiece base installing hole described in the vertical face of the through-hole.
The level of the pedestal (usually technique pedestal) of the horizontal profile and workpiece to be mounted of the workpiece base installing hole
Profile is consistent, generally polygon, and to prevent circumferentially rotating for workpiece, preferably rectangle, structure is simpler.
The horizontal direction linear dimension of the workpiece base installing hole 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 base installing hole and the pedestal of workpiece answers smaller, and the work
Assembly precision between part base installing hole and the pedestal of workpiece should at least be not less than the precision prescribed of workpiece.
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 base installing hole 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 base installing hole, to fix the workpiece in the height direction.
The pin hole radially extended 212 and 32, installation condition can be each provided on the workpiece mounting portion and clamping cap
Under, a positioning pin 4 is also cross the two pin holes on the workpiece mounting portion and clamping cap and matched.The pedestal with
Radial pin connection is carried out between clamping cap, and the threaded connection between pedestal and clamping cap described in process can be effectively prevented
Loosening is generated under the outer force-disturbances such as vibration, keeps clamping more reliable.
Threaded connection between the pedestal and clamping cap is preferably threadedly coupled using limit.What the limit was threadedly coupled
Structure specifically: radial concave point 213, the internal threaded regions of the clamping cap are equipped in the external screw thread region of the workpiece mounting portion
Relative position is equipped with radial salient point (not shown) in domain, and during screw thread screws, salient point is interfered with concave point
Phenomenon, the salient point are embedded in the angular limit function that the concave point realizes screw thread, make on the workpiece mounting portion and clamping cap
Two pin hole alignment, convenient for the plug of positioning pin.
The depth of the concave point is about 0.2-0.3mm, and there is flash on concave point periphery.
When installation, workpiece is first packed into the workpiece base installing hole on the pedestal, is then revolved on the pedestal
The tight clamping cap, until the concave point that the salient point insertion pedestal external threaded surface of interior threaded surface setting is arranged on clamping cap, this
Shi Suoshu pedestal is overlapped with the axis of the pin hole of clamping cap, and the positioning pin is finally injected in two pin holes.
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.
