Abstract
The utility model relates to a high-precision hole positioning device, which belongs to a hole positioning device of a special detection fixture of machining parts. A taper key is positioned in a taper key way on a body, a connecting piece is sleeve-jointed at one end of the taper key, the connecting piece is connected with the body through a guiding screw in sliding way, and a spring piece is connected with the connecting piece through the key. The utility model has the advantages: the structure is novel, the device can accurately locate the center of a part hole, so the error of the measuring result of the detection fixture is extremely similar to that of the three-dimensional measuring result, the measuring result of the detection fixture is genuine and believable, and users can accept the measuring result.
Description
Technical field
The utility model belongs to the hole positioning device of the special-purpose inspection jig of machine-made spares.
Background technology
Localization part is the position of placing tested zero, parts reference field or datum hole, therefore is also referred to as standard apparatus.Its effect is to make the reference field of tested part and measurement mechanism keep certain relative position, thereby guarantees the rationality and the stability of measurement.The stability of location is the most critical link in the inspection jig design, and the choose reasonable location is the basis that guarantees measurement accuracy.Inspection jig not location just can not be worked, and locatees unreasonablely, also can make the measuring error increasing of inspection jig, finally causes and can not use.
At present in the special-purpose inspection jig design of machine-made spares, when relating to the high accurate hole location, usually adopt grouping mandrel location, be easy to generate the gap between hole and the axle like this, the product hole can not accurately be located, the resultant error of measurement result and three-dimensional coordinates measurement is very big, makes the user not accept measurement result.
Summary of the invention
The utility model provides a kind of high accurate hole locating device, the big problem of measuring result error that exists when adopting grouping mandrel location to solve.The technical scheme that the utility model is taked is: the tiltedly strong taper key groove that is positioned on the body, and web member is socketed in a tiltedly strong end, and web member and body are slidingly connected by guider screw, and spring leaf is connected with web member by key.
The utility model advantage is a novel structure, and it can accurately locate the center in product hole, makes the resultant error of inspection jig measurement result and three-dimensional coordinates measurement very close, makes the inspection jig measurement result genuine and believable, thereby makes the user accept measurement result.

Embodiment
The tiltedly strong 1 taper key groove that is positioned on the body 3, web member 2 are socketed in a tiltedly end of strong 1, and web member 2 is slidingly connected by guider screw 6 with body 3, and spring leaf 5 is connected with web member 2 by key 4.
By tiltedly strong 1 changing diameter dimension with the relative motion of web member 2, the elastic force by spring leaf fixes diameter dimension, plays Self-centering Action, makes the location very accurate.
Claims (1)
1. high accurate hole locating device is characterized in that: the tiltedly strong taper key groove that is positioned on the body, and web member is socketed in a tiltedly strong end, and web member and body are slidingly connected by guider screw, and spring leaf is connected with web member by key.
