Abstract
The utility model provides a calibration sphere deposited randomly, which comprises a magnet steel 1, a magnet steel sheath 7 out of the magnet steel and a caulking 8 on the magnet steel sheath; wherein, the magnet steel and the magnet steel sheath are arranged in the magnet steel base 6. The utility model also comprises a calibration sphere 3 which is fixed on a connecting bar 4 with the other end arranged in the magnet steel base and a bolt 5 is provided between the connecting bar and the magnet steel base. After loosening the bolt, the connecting bar can rotate within the scope of 180 degrees. When being in alignment with the calibration, the measurement rod can be fixed by bolts. The magnet steel of the utility model will catch up any place necessary for placing the calibration sphere. The calibration work can be realized regardless of the dimensions of the gears. If only the end area of the gear is more than that of the magnet steel, the calibration sphere can realize the function of calibration. The utility model has the advantages of simple structure, convenient processing and reliable deposition.
Description
(1) technical field
The utility model relates to a kind of detecting instrument, specifically a kind of device that is used for the gear calibration.
(2) background technology
Gear measuring center is when detecting the gear of size Φ 0-Φ 300mm, and calibrating stem is when calibration ball, and measuring error is in allowed band.But when detecting size greater than the gear of Φ 300mm, because measuring staff is long, there is " shake " phenomenon in calibrating stem when calibration ball.Like this, will bring measuring error.Particularly when the gear that detects greater than φ 1000mm, calibrating stem can't touch calibration ball at all, causes and can't accurately detect.
(3) summary of the invention
The purpose of this utility model is to provide a kind of placement calibration ball at random no matter the gear size all can accurately be measured.
The purpose of this utility model is achieved in that it comprises magnet steel 1, magnet steel has magnetic steel sleeve 7 outward, have stifled 8 on the magnetic steel sleeve, magnet steel and magnetic steel sleeve are assemblied in the magnet steel seat 6, it also comprises calibration ball 3, calibration ball is fixed on the connecting link 4, and the other end of connecting link is assemblied in the magnet steel seat, and is provided with screw 5 between connecting link and the magnet steel seat.
The utility model can also comprise some architectural features like this:
1, fixedlying connected between the calibration ball of being narrated and the connector is riveted joint.
2, the other end of described connecting link is that connecting link cooperates at the magnet steel seat internal clearance with assembling between the magnet steel seat.
The utility model is after unclamping screw 5, and connecting link can rotate in 180 ° of scopes.After sounding rod and calibrated sphere position alignment, available screw 5 is fixed.The end face of magnet steel, magnet steel seat, magnetic steel sleeve adopts correct grinding, and the surface reaches Ra0.8.Needs are placed wherein, magnet steel of the present utility model need only be held where to get final product.Its major advantage is embodied in:
1, no matter the gear size all can realize calibration operation.As long as the end area 〉=magnet steel area of gear, calibration ball just can realize its function.
2, simple in structure, easy to process, it is firm to place.No matter where gauge head is positioned at, as long as rotate calibration ball, all can contact with calibrating stem.
3,, promoted mechanical measurement to high precision, faster, the better development of high-level efficiency direction along with the development of gear measurement technology.Device of the present utility model can be used on the calibration operation on the part that detects various non-rules, can raise the efficiency, and satisfies the demand of measuring accuracy.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
(5) embodiment
For a more detailed description to the utility model for example below in conjunction with accompanying drawing:
The composition of placing calibration ball at random comprises magnet steel 1, and magnet steel has magnetic steel sleeve 7 outward, has stifled 8 on the magnetic steel sleeve, magnet steel and magnetic steel sleeve are assemblied in the magnet steel seat 6, calibration ball 3 is fixed on the connecting link 4, and the other end of connecting link is assemblied in the magnet steel seat, and is provided with screw 5 between connecting link and the magnet steel seat.Fixedlying connected between the calibration ball of being narrated and the connector is riveted joint.The other end of described connecting link is that connecting link cooperates at the magnet steel seat internal clearance with assembling between the magnet steel seat.
Claims (3)
1, a kind of calibration ball of placing at random, it comprises magnet steel (1), magnet steel has magnetic steel sleeve (7) outward, have stifled (8) on the magnetic steel sleeve, magnet steel and magnetic steel sleeve are assemblied in the magnet steel seat (6), and it also comprises calibration ball (3), it is characterized in that: calibration ball is fixed on the connecting link (4), the other end of connecting link is assemblied in the magnet steel seat, and is provided with screw (5) between connecting link and the magnet steel seat.
