AI Technical Summary

Technical Problem

During the machining of existing bearing housings, the positions of the pressure grooves and threaded holes of the upper and lower fixed seats are prone to deviation, which can lead to the bearings being unable to be installed or not being securely fixed, making it difficult to meet the accuracy requirements.

Method used

An integrated processing device for threaded holes in bearing seats is adopted, which integrates casting, positioning, drilling and tapping, and grooving. The casting mechanism forms the blank, the positioning mechanism precisely positions it, the first processing mechanism drills and taps simultaneously, and the second processing mechanism forms the groove, realizing the synchronous, efficient and precise processing of the upper and lower fixed seat blanks.

Benefits of technology

Ensure precise alignment of the upper and lower fixed seats to improve assembly accuracy, reduce positional deviations, increase processing efficiency and product quality, and meet the production requirements of high-precision bearing seats.

Abstract

This invention discloses an integrated machining device for threaded holes in bearing housings, relating to the field of bearing housing machining technology. This integrated machining device integrates casting, positioning, drilling and tapping, and grooving to achieve simultaneous machining of the upper and lower fixed housing blanks, avoiding positional deviations in the grooving and threaded holes caused by step-by-step machining, ensuring precise alignment and improving assembly accuracy. The positioning mechanism utilizes an auxiliary rod to pre-form holes, which are then fixed by the insertion of a mounting plate and radial expansion of the positioning component, ensuring coaxiality of the two blanks. The first machining mechanism employs a drilling and tapping method with simultaneous advancement and rotation, achieving efficient and precise machining. The second machining mechanism uses an adjustable-radius rotary milling cutter to precisely form the grooving. The casting mechanism can be flipped for demolding, creating a closed machining environment to reduce debris splashing, and automatically cleaning debris, reducing maintenance costs. The overall process is highly integrated and automated, significantly improving processing efficiency and product quality, meeting the production requirements of high-precision bearing housings.
