Technical Field

[0001] The invention relates to the technical field of press-fitting machines, and in particular to a gear press-fitting error-proofing fixture which can be adjusted quickly. Background Art

[0002] Gear press fitting refers to a processing technology that uses mechanical pressure to assemble gears to shafts or other components. Usually, gears undergo heat treatment, grinding and other processes during the manufacturing process, and the press fitting process is mainly to accurately fix the processed gears to the predetermined position. Reasonable pressure needs to be controlled during the press fitting process. Excessive pressure may cause damage to the gears or shafts, and too little pressure may cause loose assembly. The accuracy of press fitting directly affects the working performance of the gears, especially the matching requirements of gears and shafts need to meet strict tolerance standards.

[0003] There are still some problems when pressing existing gears, such as:

[0004] Due to manual operation or inadequate fixture design, gears may appear on the front and back sides incorrectly during assembly, affecting production efficiency and quality.

The active fixture automatically adjusts the front and back sides to avoid manual inspection and rework. The fixed fixture precisely clamps to ensure the position accuracy of the gears during assembly, improves production efficiency, and reduces operational errors and manual intervention during assembly.
