Abstract
The utility model relates to a V-shaped groove locating and eccentricity clamping mechanism of a center. In the process of measuring a shaft workpiece, the center is adopted as a locating component, which has a higher requirement to the reliability of the locating and clamping of the center. However, the precision of locating is lower, thus being hard to achieve the locating and clamping when the center distance of the center is smaller. The V-shaped groove locating and eccentricity clamping mechanism of the center consists of a vertical shaft (1). The vertical shaft (1) is fixed with a locating workpiece V-shaped block (9). A locking block (8) is arranged inside the vertical shaft (1) and the center (10) is arranged inside the through groove of the locking block (8) and the V-shaped groove of the locking block (8). An eccentric shaft (7) is arranged inside the locking block (8) and the two ends of the eccentric shaft (7) are supported on the vertical shaft (1). The eccentric shaft (7) tensions the locking block (8) through a bolt (4) in a tension device (12). The mechanism is applicable to a general measuring instrument of a two-flank gear rolling.
Description
Technical field: the utility model relates to a kind of top V-shaped groove location and eccentric clamp mechanism.
Background technology: in the measuring process of shaft-like workpiece, generally adopt top as setting element, therefore higher to top the location and the reliability requirement of clamping on measuring instrument.The last top of the existing pair of two-sided engagement general measuring instrument of column gear is to realize the location by the inner cylinder face of column, though this localization method is simple, clamping is convenient to realize, but the accuracy of location is relatively low, especially be subjected to the restriction of column wall thickness, be difficult to realize location and the clamping hour of top centre-to-centre spacing.
Summary of the invention: the purpose of this utility model provides a kind of can measuring center the location and eccentric clamp mechanism apart from the top V-shaped groove of less stem gear on the two-sided engagement general measuring instrument of two column gears.
Above-mentioned purpose realizes by following technical scheme:
Top V-shaped groove location and eccentric clamp mechanism, its composition comprises: column, described column and setting element vee-block are fixed, latch segment is equipped with in the inside of described column, be equipped with top in the V-shaped groove of the groove of described latch segment and described setting element vee-block, in the described latch segment eccentric shaft is arranged, the two end supports of described eccentric shaft is on described column, and described eccentric shaft is by the tension of the screw in take-up device latch segment.
Above-mentioned top V-shaped groove location and eccentric clamp mechanism, described take-up device comprises spring, described spring is installed between spring blind rivet and the arm-tie, described spring blind rivet is contained on the column, described arm-tie is contained on the described latch segment, described latch segment and described arm-tie are strained with described screw, on the described screw nut are arranged.
Above-mentioned top V-shaped groove location and eccentric clamp mechanism, described setting element vee-block and described column are screwed.
This technical scheme has following beneficial effect:
1. top V-shaped groove of the present utility model location and eccentric clamp mechanism, can be on the two-sided engagement general measuring instrument of two column gears measuring center apart from less stem gear, measure accurately, can make the minimum centers-distance of tested gear shaft reach 20mm, in the type measuring instrument, realized the breakthrough of minimum centers-distance measurement category.
2. this mechanism has realized top reliable location and clamping because of employing has the eccentric shaft of auto-lock function.
3. nut is equipped with in this mechanism on screw, can prevent that screw from becoming flexible in the course of the work.
4. the spring of this mechanism is installed between spring blind rivet and the arm-tie, makes latch segment remain certain pulling force to top, and can avoiding unclamping the eccentric shaft back centre like this, to produce bigger string moving, and top the realization relocated stably.
