Abstract

The title of the present invention is a milling fixture for crankshaft speed sensor main body assembly. It belongs to the technical field of fixtures. It mainly solves the problem that the existing wire cutting process cannot meet the mass production of factories due to low production efficiency. Its main features are: including the right body and the left body; the upper part of the right body is the right half-step hole body, the lower part is the right seat body, and the right seat body is provided with two identical right step holes, and the hole direction of the right step hole is It is perpendicular to the hole direction of the right half-step hole body; the upper part of the left body is the left half-step hole body, the lower part is the left base body, and the left base body is provided with two identical left step holes, and the left step hole is aligned with the left The hole direction of the half-step hole body is vertical; the right base body is the same as the left base body, and the right half-step hole body and the left half-step hole body have the same size and opposite directions. The invention has the characteristics of quickness, convenience and high processing efficiency, and is mainly used for the milling process of the main body assembly of the crankshaft speed sensor and the similar ABS body assembly whose shape of the clamping end cannot be clamped.

Description

technical field

[0001] The invention belongs to the technical field of fixtures for crankshaft speed sensors, and in particular relates to a milling fixture for a main body assembly of a crankshaft speed sensor. Background technique

[0002] At present, the requirements for engine emissions are getting higher and higher, and the emissions must meet the requirements of Euro III or National IV. The present invention is aimed at a milling fixture for Euro III Weichai crankshaft speed sensor main body assembly. Since the main body assembly of the crankshaft speed sensor is molded several times, it is necessary to leave the necessary intermediate metal mandrel process head for this process during injection molding, but this process head must be removed after the final molding. Since the main body assembly of the crankshaft speed sensor has a complex shape after injection molding, the three-jaw chuck or spring collet on the lathe cannot clamp the main body assembly, so that the t...
