The state of reason.
One easy self-checking unit 3 with one heart is installed above the seat of honour 16 of pivot mechanism 1, the device can be first
Concentric locating detection is carried out to three claws 27 when step installs the positioning fixture.
When positioning fixture is tentatively installed, it is necessary to which the annular workpieces 5 of a standard calibrate the concentric essence of three claw groups 2
Positioning fixture, is first tentatively installed in place, i.e., first the kidney-shaped mounting hole on one of bottom plate 20 hangs down with its length direction by degree
Straight claw group 2 is transversely mounted on the work top 4 of drilling machine (parallel with the horizontal T-slot on the work top 4 of drilling machine),
Two other claw group 2 is respectively arranged on the work top 4 of drilling machine with mounted claw group 2 into 120 ° of at an angles again
(the kidney-shaped mounting hole opened up on the bottom plate 20 of the two claw groups 2 is parallel with its length direction), then a standard component 5 is passed through
Contour support block 50 is placed in three claw groups 2, clamps standard component 5 with three claws 27, Fig. 2 is shown three claws 27 and pressed from both sides
Tightly on the inner headed face of standard component 5, pass through the infra-red ray detection device installed on drilling machine, the circle of the standard component 5 after detection clamping
Whether the center of circle of the heart and the mandrel 11 for passing the seat of honour 16 is in same point, if not same point is, it is necessary to pass through concentric self-checking unit 3
It is concentric between three claws 27 to detect, the push rod of the dial gauge 34 of concentric self-checking unit 3 is leaned against to the outside of standard component 5
Face, while the bearing roller 354 of sag-resistant mechanism is against to the upper surface of standard component 5, concentric self-checking unit 3 is rotated, makes percentage
Periphery of the table 34 along standard component 5 turns around, and observation dial gauge 34 just can measure the shift value of some claw 27, then pass through
Operation handle finely tunes the position of the claw 27, to ensure that three claws 27 are concentric.Concentric self-checking unit is removed after adjustment
3, machined for annular element end-face hole just can be carried out, then sets the center of drilling machine as the circle centre position, it is fixed to be installed after can making
The center of circle of whole workpiece need not be detected during the workpiece of position, it is only necessary to which the home position of the mandrel 11 in seat of honour 16 of detection is daily
It is no to be varied from.Enable workpiece after so doing quickly and accurately repeated clamping.
Periphery to be clamped in standard component 5, first three claw bodies 271 are reversibly mounted on claw base 270
And be displaced outwardly expanding, standard component 5 is placed in the inner side of claw body 271 to be clamped.
After positioning fixture using the present invention, installation one workpiece of positioning only needs a quarter of an hour, compared to former each work
Three point measure and the calculating to home position are also carried out after part installation positioning, the installation positioning of a workpiece just needs one and half
Hour to two hours, greatlys save the time to wait in workpiece process.
The positioning fixture of the present invention, the diameter of work for installing positioning is 1.5 meters to 4 meters, is highly 100mm to 300mm, its
The precision of repeated clamping is within 0.05mm, while guaranteed efficiency, can also ensure higher repeated clamping precision.
1. the positioning fixture of the present invention can carry out the detection of self precision, because Rig up error causes three when avoiding installing
Individual claw install positioning the workpiece center of circle and the customized center of circle of table top it is misaligned；
2. the positioning fixture of the present invention is after installation and debugging completion, except unit one needs to check the center of circle, behind
Need not be checked, and dismount simple, repeatable accuracy is high；
3. the positioning fixture of the present invention can carry out clamping to the external diameter or internal diameter of annular workpieces, without annular workpieces
Outer rim or inner edge are all simultaneously full circle, therefore applicability is more extensive.
Above example is used for illustrative purposes only, rather than limitation of the present invention, the technology people about technical field
Member, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all equivalent
Technical scheme should also belong to scope of the invention, should be limited by each claim.
