Abstract
The invention discloses a self-centering clamp of an internal gear ring and gear measuring instrument. The self-centering clamp comprises a base (2), a measuring instrument (5) and a measured gear ring (4), locking bolts (1) are arranged at the bottom of the base (2), and the base (2) is fixed with the measuring instrument (5) through the locking bolts (1). Arc-shaped openings (6) are formed at the positions, corresponding to the measured gear ring (4), of the upper surface of the base (2). A measuring bar (3) is arranged at the edge of each arc-shaped opening (6), and the measured gear ring (4) is disposed on the measuring bars (3), and is rotated to enable the measuring bars (3) to be located in tooth spaces of the measured gear ring. The self-centering clamp of the internal gear ring and gear measuring instrument has the advantages that the measuring bar is adopted to replace a cylinder and positioning column structure in an existing device, and accordingly cost is saved, processes are simplified, and a self-locking function can be well realized.
Description
Technical field
The present invention relates to a kind of inner gear ring gear measurement instrument self-centering fixture.
Background technology
In the production technology of automobile gear, the very important characteristic when accuracy class of bull gear is Element Design and manufacture, the quality of this characteristic has directly had influence on the overall performance of part, to such an extent as to affect noise and the transmission efficiency of whole speed changer.The accuracy class of bull gear is all to measure by gear measurement machine now, but detect with domestic gear testing amount instrument, at first will make the axle center of the reference circle of gear ring and measuring instrument concentric, be generally by showing with dial gauge and artificial reference circle to reach gear ring and the concentric state in axle center of measuring instrument adjusted.So both unstable, and efficiency is very low.
Summary of the invention
The invention provides a kind of inner gear ring gear measurement instrument self-centering fixture, adopt length bar to substitute cylinder and the locating dowel structure in existing apparatus, both save cost, simplified operation, can well realize auto-lock function, can directly make fast and accurately again the axle center of the reference circle of gear ring and measuring instrument concentric, thereby improve detection efficiency, reduce measure error.
The present invention has adopted following technical scheme: a kind of inner gear ring gear measurement instrument self-centering fixture, and it comprises base, measuring instrument and tested gear ring, in the bottom of base, is provided with clamping screw, described clamping screw is fixed base and measuring instrument; The upper surface and the tested gear ring corresponding position that it is characterized in that described base are provided with arc opening, at the edge of arc opening, are provided with length bar, and tested gear ring is placed on length bar, by rotating tested gear ring, make length bar be arranged in the teeth groove of tested gear ring.
The upper surface of described base is arranged with three arc openings, and the edge of each arc opening is equipped with a length bar.
The present invention has following beneficial effect: the present invention adopts length bar to substitute cylinder and the locating dowel structure in existing apparatus, both save cost, simplified operation, can well realize auto-lock function, can directly make fast and accurately again the axle center of the reference circle of gear ring and measuring instrument concentric, thereby improve detection efficiency, reduce measure error.
The accompanying drawing explanation
Fig. 1 structural representation of the present invention.
Fig. 2 is for being top view of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, the present invention is a kind of inner gear ring gear measurement instrument self-centering fixture, and it comprises base 2, measuring instrument 5 and tested gear ring 4, in the bottom of base 2, is provided with clamping screw 1, and described clamping screw 1 is fixing with measuring instrument 5 by base 2; The upper surface of described base 2 and tested gear ring 4 corresponding positions are arranged with three arc openings 6, the edge of each arc opening 6 is equipped with a length bar 3, tested gear ring 4 is placed on length bar 3, by rotating tested gear ring 4, make length bar 3 be arranged in the teeth groove of tested gear ring, rotate gear ring according to the direction of arc opening, now the reference circle of gear ring is just concentric with the axle center of measuring instrument, and length bar is locked gear ring.
