A kind of differential spider hole processing tool
The utility model relates to the Machining Technology field, specifically a kind of differential spider hole processing tool.
At present domestic mechanic factory workers is in production and processing, processing to the cross shaft hole of differential mechanism product generally all is that the horizontal milling machine that uses is processed, do not use the frock clamp of special secondary process, often positional precision is inconsistent for the corresponding cross shaft hole at two 180 degree angles that are separated by of the workpiece that processes like this, do not cooperate, do not meet the quality requirement of product demand producer, cause the loss of customer resources, and the labour intensity of common process is very large, the waste of material is also relatively large, the production efficiency of factory is very low, and the development of enterprise is very difficult.
The utility model content
For the deficiency that above-mentioned similar technical problem exists, the purpose of this utility model provides a kind of differential spider hole processing tool.
The technical solution of the utility model is: a kind of differential spider hole processing tool, comprise that workpiece fixing seat, location are from expansion core axle, supporting spring piece, angle locating shaft, it is characterized in that: the center of workpiece fixing seat is provided with a location from the expansion core axle, the location is provided with a supporting spring piece from the top of expansion core axle, the end face of workpiece fixing seat also is fixed with an angle locating shaft.
Described supporting spring piece can be elastic.
The utility model has the advantages that: by using this frock the cross shaft hole of differential mechanism is processed, not only reduced greatly workman's labour intensity, and can improve greatly the machining accuracy of product, the positional precision of the corresponding cross shaft hole at two 180 degree angles that are separated by of differential mechanism is very high, the qualification rate of product is greatly improved, satisfy the requirement of client to product quality, improved production efficiency and the competitiveness of enterprise.
