Abstract
The utility model relates to a pitch circle six-point positioning fixture, which is used for controlling concentricity of a load driven spiral bevel gear inner bore and a pitch circle. The pitch circle six-point positioning fixture consists of a fixture component and six positioning ball heads. The six positioning ball heads are uniformly distributed at six fixed positions of the fixture positioning components according to the number of teeth of a driven bevel gear of a processed part. The driven bevel gear is arranged on the six positioning ball heads to be fixed and positioned, and then is machined on a fixture of a grinding machine after being locked by a fastener. The pitch circle six-point positioning fixture is characterized in that three positioning points are changed into six positioning points, thereby being capable of reflecting actual deformation condition of heat treatment of gears, increasing positioning precision of pitch circles of gears, effectively guaranteeing consistency of concentricity of the grinded gear inner bore and the pitch circle, and then meeting requirements on gear contact precision and meshing quality.
Description
Technical field
The utility model relates to the improvement of a kind of pitch circle positioning fixture and method, is specifically related to a kind of pitch circle six point location anchor clamps, in order to the concentricity of control driven spiral bevel gear endoporus of loading machine and pitch circle.
Background technology
Prior art when grinding loading machine driven wheel of differential endoporus, employing be pitch circle three-point fix anchor clamps and localization method, as shown in Figure 1.Because gear has distortion when heat treatment, with pitch circle three-point fix mill endoporus, though more advanced than scroll chuck folder cylindrical location, but can not fine assurance endoporus and the concentricity of pitch circle, thereby the gear contact precision influenced.
The purpose of this utility model is to improve positioning fixture, improves positioning accuracy.
The utility model content
To achieve these goals, the utility model adopts following scheme:
Pitch circle three-point fix anchor clamps are improved to pitch circle six point location anchor clamps.Because gear heat treatment has distortion, anchor point can reflect gear heat treatment deformation reality after increasing at 6 by 3 better, improves the pitch circle positioning accuracy, guarantee that effectively concentricity and pitch circle after the bore grinding are consistent, thereby reach gear contact precision and meshing quality requirement.
Description of drawings
Fig. 1 is prior art pitch circle three-point fix anchor clamps schematic diagrames.
Fig. 2 is a structural representation of the present utility model, and it is made up of clamp body assembly and six location bulbs.
Fig. 3 is six location bulb position views in the utility model anchor clamps.
Specific embodiments
The utility model is described in further detail below in conjunction with embodiment:
With reference to shown in Figure 2, pitch circle six point location anchor clamps are made up of clamp body assembly and six location bulbs.With reference to shown in Figure 3, six location bulbs are evenly distributed on six position locations in the anchor clamps positioning component according to the number of teeth of part to be processed driven wheel of differential.Driven wheel of differential is placed on stationary positioned on six location bulbs, is locked on the anchor clamps of grinding machine with securing member then and processes.It is characterized in that, anchor point changes 6 points into by 3, can reflect the actual conditions of gear heat treatment deformation better, improves the pitch circle positioning accuracy, guarantee that effectively concentricity and pitch circle after the bore grinding are consistent, thereby reach gear contact precision and meshing quality requirement.
