Described camshaft signal wheel positioner comprises that suit is supported on the locating ring that supports the pillar top, the end face of described locating ring is provided with the alignment pin that is used for positioning cam axis signal wheel, and the arranged outside of locating ring is useful on locating ring is fixed on the fastening bolt that supports on the pillar.The locating ring suit is supported on and supports the pillar top, can be that rotate at the center to support pillar, adjust after the corner that locating ring supports pillar (being relative camshaft) relatively according to the design needs, screw the fastening bolt in the locating ring outside, locating ring is fixed, then the wheel of the signal after the heating is stuck on the alignment pin of locating ring end face, has so just realized the location of camshaft signal wheel with respect to camshaft.
The end face of described locating ring has endless groove or a plurality of locating hole, and described alignment pin is installed in endless groove or the locating hole.The position of alignment pin and angle just can be taken turns according to concrete camshaft signal and be adjusted like this, increase the scope of application.
Described alignment pin can be avoided the rotation of folk prescription camshaft signal wheel when the location like this for being installed in the bulge-structure on the locating ring both direction at least.
Described fastening bolt is at least three, the angle of the angle of adjacent two fastening bolts is identical, can not only guarantee that like this locating ring is fixed on suitable angle, can also prevent from when press-fiting the camshaft signal wheel, to cause the inclination of locating ring, guarantee to press-fit precision because of unbalance stress.
The top of described support pillar is provided with and supports the seat of honour that pillar is fixedlyed connected, and described camshaft signal wheel positioner is movably arranged on the top at the seat of honour.
The bottom of described support pillar is provided with and supports following that pillar is fixedlyed connected, and it is inner that described camshaft location structure is arranged on down seat.
Fixedly connected by screw thread with supporting between the pillar in the described seat of honour.
Fixedly connected by screw thread with supporting between the pillar for described following, following bottom is provided with the screwed hole that is used for fixing rubber cushion.
Support following that pillar is provided with the seat of honour of camshaft signal wheel positioner and/or has the camshaft location structure, can be to signal wheel shaft neck length degree not simultaneously at the camshaft front end, support the needs that press-fit that pillar satisfies different camshafts by changing, increase the scope of application.
Fixedlying connected by screw thread with supporting between the pillar in the described seat of honour, following, is convenient for changing.
Described following bottom is provided with the screwed hole that is used for fixing rubber cushion, and the bottom fixes rubber cushion during use, so that play the effect of buffering and damping when press-fiting.
Each parts dismounting flexibly of engine camshaft signal wheel press-installation fixture of the present utility model, the arbitrarily conversion adjustment of angle of location, cam shaft can also be changed when change in size and support pillar to adapt to variation, its practicality is strengthened greatly, break the limitation of single product frock, be suitable for the press-fiting of various camshaft signals wheel of development phase.
