A kind of precision shaft docking equipment and precision shaft docking method

Abstract

The invention discloses a precision shaft docking device, which includes a straightening part sleeved on the first shaft, a detection part and a correction part sleeved on the second shaft, and the straightening part, the detection part and the correction part are coaxial Distributed and fixedly connected to each other, the alignment part and the detection part are respectively installed with distance sensors for obtaining the surface radian information of the first axis and the second axis, and the distance sensors on the detection part acquire at least two Set the radian information to determine the radial and axial deviation between the first shaft and the second shaft. The correction part is equipped with a force application device for hitting the surface of the second shaft to correct the deviation. The precision shaft docking method is to use the correction part and the The detection part obtains the deviation between the two shafts, and the correction part is used to correct the deviation to realize the precise shaft connection between the first shaft and the second shaft. Direct and radial bi-directional deviation, and then directly realize the bi-directional precise docking between the two shafts.

Description

Technical field[0001]The present invention relates to the technical field of mechanical assembly production equipment, and more particularly to a precision axis docking device and a precision axis docking method.Background technique[0002]During the assembly or production of precision drive, two parts or multiple parts required to be coaxial degree are usually installed together, and the common form includes a connection between the shaft parallel, and the flange is flanged between the flanged shaft. The mutual attachment of the end faces, and the like. In order to achieve coaxial requirements between the shaft and the shaft, it is often achieved by some auxiliary devices, and there are many forms of existing auxiliary devices, such as universal joints, couplings, spherical bearings, and the like. However, there is also no connection between the shaft and the shaft, and the direct connection between the shaft and the shaft is also more common during the assembly and measurement of th...

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
