Description

A kind of high accuracy centering tool device
Technical field
The utility model relates to a kind of centering tool device,, especially a kind of high accuracy centering tool device.
Background technology
Milling train is the equipment of metallurgy industry extensive use, and quill shaft is the main parts size on the coiling machine in the milling train.And quill shaft generally all is to process on large-scale high-precision numerical control door frame milling machine, and the centering instrument plays critical effect in this process.At present, the domestic high accuracy centering tool device that still lacks, many parts can only be processed on plain-milling machine, and this has just increased difficulty of processing greatly, and precision can't guarantee.Because this type of product consumption of metallurgy industry is big, processing can not be satisfied the production needs far away on Digit Control Machine Tool now.
Summary of the invention
In order to solve the problem of quill shaft machining accuracy, the utility model provides a kind of high accuracy centering tool device, and this survey tool can not only guarantee the centering required precision, and volume is little, quick and convenient, the highly versatile of operation.
The technical solution of the utility model is by centering plate 1, centering chi 2, U-lag 3, straight pin 4, attachment screw 5, adjust screw 6, arc clamp 7 is formed, wherein centering plate 1, centering chi 2, U-lag 3, straight pin 4, attachment screw 5 interconnect forms the centering body; Center at centering plate 1, be provided with a datum hole, four point of interface places at two the orthogonal diameters and the excircle of circular centering plate 1, be respectively arranged with four U-lags 3 that size is identical, both sides at U-lag 3, along being parallel to diametric(al), by straight pin 4 a rectangular centering chi 2 is installed respectively, and the measurement face of centering chi 2 is parallel with two orthogonal diameters of datum hole respectively, by attachment screw 5 centering chi 2 is fixed on the centering plate 1, on the excircle of centering plate 1, be installed with and adjust screw 6, arc clamp 7 is arranged, promptly constitute high accuracy centering tool device described in the utility model at the next door card of adjusting screw 6.
The beneficial effects of the utility model are, can guarantee the high accuracy centering, and easy to operate, simple in structure, highly versatile.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is centering body structure figure in this high accuracy centering instrument.
Fig. 2 is clamp minor structure figure in this high accuracy centering instrument.
Among Fig. 1: 1. centering plate, 2. centering chi, 3.U shape groove, 4. straight pin, 5. attachment screw, 6 adjust screws, 7. arc clamp.
The specific embodiment:
A kind of high accuracy centering tool device of the utility model as shown in Fig. 1,2, be by centering plate 1, centering chi 2, U-lag 3, straight pin 4, attachment screw 5, adjustment screw 6, arc clamp 7 are formed, wherein centering plate 1, centering chi 2, U-lag 3, straight pin 4, attachment screw 5 interconnect forms the centering body; Center at centering plate 1, be provided with a datum hole, four point of interface places at two the orthogonal diameters and the excircle of circular centering plate 1, be respectively arranged with four U-lags 3 that size is identical, both sides at U-lag 3, along being parallel to diametric(al), by straight pin 4 a rectangular centering chi 2 is installed respectively, and the measurement face of centering chi 2 is parallel with two orthogonal diameters of datum hole respectively, attachment screw 5 is fixed on centering chi 2 on the centering plate 1, on the excircle of centering plate 1, be installed with and adjust screw 6, arc clamp 7 is arranged, promptly constitute high accuracy centering instrument described in the utility model at the next door card of adjusting screw 6.
During use locating hole on the centering body is enclosed within on the big end cylindrical of part to be processed quill shaft, locating hole end face and part to be processed quill shaft end face are adjacent to, adjusting is along the radially adjustment screw 6 of datum hole circumference uniform distribution, the datum hole center that processes in advance on the datum hole and quill shaft on the centering body is overlapped, promptly be that this centering tool positioned benchmark overlaps with the part to be processed machining benchmark, eliminated the error of installing and using of this alignment device like this.With arc clamp 7 the centering body is clamped on the quill shaft then, promptly finishes this centering.
