The high-accuracy centring device for assembling the hole shaft parts comprises a body, a base seat, a supporting frame, a swing arm, hole part fixing pieces, a hole guide assembly power cylinder, a shaft guide assembly power cylinder, a hole guide assembly, ashaft guide assembly and a shaft pushing and clamping assembly; the base seat, the supporting frame and the swing arm are installed on the body, the supporting frame is located on the base seat, and the swing arm is located between the base seat and the supporting frame; the hole part fixing pieces are arranged on the base seat and are used for loading a hole part; the hole guide assembly power cylinder and the shaft guide assembly power cylinder are correspondingly and fixedly installed on the swing arm; the hole guide assembly is connected to the hole guide assembly power cylinder through afirst connecting rod, and the shaft guide assembly is connected to the shaft guide assembly power cylinder through a second connecting rod; and the shaft pushing and clamping assembly is arranged on the supporting frame and is used for loading a shaft part. According to the high-accuracy centring device for assembling hole shaft parts, the centring accuracy is high, the efficiency is high, the stability is good, a matching surface of a loaded product is protected conveniently, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the field of automatic assembly equipment for hole-shaft parts, in particular to a high-precision centering device and method for assembling hole-shaft parts. Background technique [0002] Hole-shaft assembly products are widely used in various industrial fields, such as the hydraulic servo actuator industry. The accuracy and reliability of the assembly of hole-shaft parts greatly affect the quality and working stability of the product. Effective assembly The previous centering link is particularly important, especially when it comes to the assembly of seals and small gaps, poor centering accuracy will cause damage to related components or surface quality defects. During high-precision assembly, manual alignment is extremely difficult. The use of automated assembly alignment is an important guarantee for improving product consistency and eliminating the influence of external factors. Especially when large parts are assembled, m...
