Abstract

The present invention relates to a novel synchronous precision detection device and method for a gear rolling machine. It solves the technical problem that after the existing assembly is completed, it is necessary to wait until the parts are processed to know the quality of the synchronous performance of the machine tool. It includes an upper bed and a lower bed that are arranged in parallel and correspond to each other, and a processing space is formed between the upper bed and the lower bed. The upper bed and the lower bed are axially movable on the side corresponding to each other, and the sliding seats are respectively connected to a gear rolling drive mechanism that can drive the two sliding seats to slide alternately.

[0002] Gear rolling machines are widely used in the processing of various involute splines, involute serrations, threads, oil grooves, screws and knurling. Gear rolling machines use two gear rolling plates to move against each other repeatedly to process teeth, keys, etc. on the surface of circular blanks. At present, after the production and assembly of gear rolling machines, it is necessary to wait until the parts are processed to know the quality of the machine tool synchronization performance. The synchronization performance of the gear rolling machine directly affects the cold rolling accuracy of the gear rolling. At the same time, there is a delay in the maintenance of the synchronization of the gear rolling machine, and failure to maintain it in time will affect the normal operation of the gear rolling machine.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a thoracoscopic fixation device [201420785601.3], including an upper cover, a base, an upper slide, and a lower slide, and the upper and lower slides are respectively connected to the upper and lower drive devices.
