Turning fixture for gleason spiral bevel gear

Abstract

The technology provides a turning fixture for an arc-teeth cone gear. The turning fixture for the Gleason spiral bevel gear can be connected to a lathe and can carry out turn an inner hole and a plane of the Gleason spiral bevel gear to improve the processing efficiency and ensure the processing quality. The turning fixture for the Gleason spiral bevel gear comprises a clamp base used for being connected with a spindle, a clamp is fixed on the clamp arc-teeth cone gear base, and a bearing plate is arranged on the clamp; at least three positioning balls, evenly located on the circumferential direction of the Gleason spiral bevel gear, are arranged on the bearing plate. The Gleason spiral bevel gear is pressed tightly on the positioning balls by three pressing plates sleeved on three pulling bars. Lower ends of the pulling bars are connected with a fork-shaped plate through the clamp; a spherical pair is formed by a center portion of the fork-shaped plate and a movable sliding block; a center screw rod is arranged on the movable sliding block to be connected to a spindle oil cylinder of the lathe; and the pressing plates are connected with the pulling bars by screw pairs.

Description

technical field [0001] The technology relates to a tool for turning a spiral bevel gear. Background technique [0002] Spiral bevel gears such as figure 1 As shown, the surface hardness of the spiral bevel gear is HRC58-62, the pitch circle of the gear is 0.06 mm to the circular runout of the inner hole, the large plane T is 0.025 mm to the circular runout of the inner hole, the flatness is 0.015 mm, and the roughness requirement is Ra1.6; Its special structure is that there is an internal spline at the front of the inner hole φ58.50.0190, the minor diameter of the internal spline is φ55.6, and the length of the relief groove φ59 between the two is only 5 mm. According to the traditional grinding method For processing, first grind the inner hole φ58.50.019 0, and then polish the T surface; the processing is time-consuming and laborious, mainly because the length of the relief groove φ59 is only 5 mm, and the back and forth movement of the grinding wheel is not easy to contr...
