The utility model discloses the device can carry out the clamping to the helical gear, and the pitch cylinder that can change different gradients comes the helical gear of the different helical angles of clamping, and the device uses helical gear tooth portion pitch circle as the benchmark, has guaranteed required precision such as helical gear terminal surface, shaft hole are beated well, has good using value widely.
Description
Technical Field
The utility model discloses a pitch circle chuck, especially a pitch circle chuck for helical gear.
Background
Gears are one of the drive components that are widely used in machines. The common gears generally comprise a bevel gear and a straight gear, and the bevel gear has the advantage that the application range of the gear is wider than that of the straight gear, so the bevel gear is frequently used in actual production, and the semi-finished product of the bevel gear is inevitably required to be reprocessed according to production requirements in the application process. At present, a gear with a larger size and an axle hole is usually clamped by matching a gear end face with an expansion mandrel, but the gear without the axle hole is not suitable; or for the gear with higher accuracy requirements such as end face and shaft hole run-out, if the method is used, the end face, the shaft hole and the like of the gear cannot meet the use requirements, and the gear is easy to wear due to run-out in the use process, so that the production benefit is influenced.
Disclosure of Invention
To above not enough, the utility model discloses the device provides a pitch circle chuck for helical gear.
The utility model discloses the device mainly includes helical gear, section cylinder, jack catch, holder, O shape circle, pillar, film dish, transition dish and push rod. The push rod penetrates through an inner hole of the transition disc to be matched with the transition disc coaxially, the thin film disc is fixed on the transition disc through a bolt and coaxial with the transition disc, three supporting columns are fixed on the thin film disc and are evenly distributed in the circumferential direction, a clamping jaw is fixed at the top of each supporting column through a screw, a joint cylinder is connected to each clamping jaw through a dovetail groove, and the O-shaped ring, the retainer and the helical gear are sequentially placed on a plane supported by inclined planes of the three supporting columns coaxially.
The utility model discloses the device includes following technical scheme:
the utility model discloses the device uses helical gear tooth portion pitch circle as the benchmark, and three pillar is that the circumference evenly fixes on the holder, all installs a jack catch on every pillar, and the pitch cylinder that the gradient is the same with helical gear helix angle degree of degrees passes through the dovetail to be fixed on the jack catch, and the jack catch can be followed the radial direction of gear and removed at the pillar top, fixes jack catch and pitch cylinder and comes the tight helical gear of the tight different diameters of clamp in suitable position, and can change the pitch cylinder of corresponding gradient to the helical gear of different helix angles.
The utility model discloses the advantage and the positive effect that the device had:
1. the device takes the pitch circle of the tooth part of the helical gear as a reference, and ensures the accuracy of the end face, the shaft hole run-out and the like of the helical gear.
2. The pitch cylinders with different inclinations can be replaced to clamp bevel gears with different helix angles.
3. Compact structure, stability and reliability.
