Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of for electric automobile gear device gear, when detecting profile of tooth teeth directional, use metering fixture.
Background technology
Form of gear tooth teeth directional measuring instrument is for measuring the instrument of involute profile error and the helix tooth alignment error of roller gear or cutter for gear wheel.At present, when electric automobile gear device form of gear tooth teeth directional is detected, fixture used comprises tapering mandrel, gear and tapering mandrel interference fit, thereby gear is fixed on mandrel, mandrel is fixed on form of gear tooth teeth directional measuring instrument and measures again, this mode, because the stationkeeping ability of mandrel is poor, make to feel relieved unreliable, measuring accuracy is poor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of electric automobile gear device form of gear tooth teeth directional metering fixture of feeling relieved reliable, measuring accuracy is high.
The technical solution of the utility model is as follows: a kind of electric automobile gear device form of gear tooth teeth directional metering fixture, it is characterized in that: comprise mandrel, gland (2) and nut (4), described mandrel comprises columniform base (1a), axostylus axostyle (1b) and screw rod (1c), described axostylus axostyle (1b) is arranged on the right side of base (1a), the right-hand member of described axostylus axostyle (1b) is established screw rod (1c), described base (1a), the diameter of axostylus axostyle (1b) and screw rod (1c) reduces successively, described base (1a), the axis of axostylus axostyle (1b) and screw rod (1c) is on same straight line, on described screw rod (1c), be set with gland (2), described gland (2) is locked by screw rod (1c) and nut (4).
Adopt technique scheme, by electric automobile gear device gear set on axostylus axostyle, with axostylus axostyle interference fit, play positioning action, on the other hand, electric automobile gear device gear one end face contacts location with base, other end contacts location with gland, avoid gear to beat, centering is reliable, has improved measuring accuracy.
In technique scheme: in order further to improve measuring accuracy, avoid gear to beat, be also set with pressing plate (3) on the screw rod (1d) between described nut (4) and gland (2).
In technique scheme: for convenient suit pressing plate, described pressing plate (3) is provided with centre bore, and described pressing plate (3) is provided with a breach communicating with centre bore (3a).When dress pressing plate, can pressing plate be enclosed within screw rod from this breach like this.
In technique scheme: be provided with cannelure (1a-1) on the right flank of described base (1a).Its effect: a reduces frock overall weight, and b plays cutter relieving effect while contributing to processing tool to lean on face grinding to guarantee to beat, and c. reduces repeated clamping face, guarantees the authenticity of measurement data.
In technique scheme: described gland is provided with centre bore on (2), the diameter of described gland (2) is less than measures part root diameter, described gland (2) is provided with circular groove (2a) near the side of axostylus axostyle (1b), and the diameter of described this circular groove (2a) should be determined according to the fitted position of institute's measuring products.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, and easy to use, easy to operate, measuring accuracy is high.
