Precision shaft butt joint equipment and precision shaft butt joint method

Abstract

The invention discloses precision shaft butt joint equipment. The precision shaft butt joint equipment comprises an aligning portion sleeving a first shaft, a detecting portion and a correcting portion, wherein the detecting portion and the correcting portion sleeve a second shaft. The aligning portion, the detecting portion and the correcting portion are coaxially distributed and fixedly connected, sensing devices for acquiring surface radian information of the first shaft and the second shaft correspondingly are mounted on the aligning portion and the detecting portion correspondingly, the sensing device on the detecting portion acquires at least two sets of radian information at different positions of the surface of the second shaft in order to determine radial and axial deviations of the first shaft and the second shaft, and a force applying device for beating the surface of the second shaft to correct the deviations is arranged on the correcting portion. The precision shaft butt joint method includes the steps that the aligning portion and the detecting portion are used for acquiring the deviations between the two shafts, the correcting portion is used for correcting the deviations, and precision shaft butt joint between the first shaft and the second shaft is achieved. A double-section detection method is adopted, the axial and radial deviations between the two shafts tobe subjected to butt joint can be directly acquired, and then two-way precision butt joint between the two shafts is directly achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly production equipment, in particular to a precision shaft butt joint equipment and a precision shaft butt joint method. Background technique [0002] In the assembly or production process of precision transmission equipment, two or more parts that require coaxiality are usually installed together. Common forms include shaft-to-shaft connections, flanges between shafts with flanges The mutual fitting connection of the end faces and so on. In order to achieve the coaxiality requirements between shafts, it is often realized through some auxiliary devices at present. The existing auxiliary devices have various forms, such as universal joints, couplings, spherical bearings, etc. However, there are also shafts that are directly connected without any connectors. The direct connection between shafts is also common in the assembly and measurement of precision transmission equipment, which is co...

Problems solved by technology

At present, for the docking of precision transmission shafts, most of the shafts are firstly detected by special instruments, and then the docking of the shafts is realized through one-to-one matching. Multiple devices are required to realize the docking of the shafts, and the detection is cumbersome. Poor interchangeability with shaft docking

At the same time, during the docking process of the two shafts, high coaxial assembly accuracy is required. The axial installation accuracy is guaranteed during the shaft docking process and the radial installation accuracy is ignored, which will easily cause discontinuous transmission or jamming, and more seriously, it will lead to the use of precision transmission parts. The life is shortened, and the machine press-in connection is prone to deformation or damage to the connecting shaft and other unfavorable factors

[0005] At present, for the butt joint of shafts between precision transmission parts, there is no operation method that satisfies high assembly accuracy, good economy and high time efficiency. In order to better solve this kind of problem, the inventor has designed a , the special equipment to realize the precision docking of shafts and shafts between transmission parts and the docking method based on this equipment
