Description
Technical Field
The invention relates to the field of coaxiality adjustment, in particular to a multi-platform coaxiality adjusting device.
Background
In some vacuum tests of mechanical mechanisms, it is often necessary to provide a drive or a load to a measured object in a vacuum tank, and therefore, apparatuses for vacuum tests generally include two types, namely a vacuum tank drive apparatus and a vacuum tank loading apparatus. The vacuum tank driving equipment is mainly used for providing external drive for a tested object to be subjected to a vacuum test and collecting parameters such as driving moment of an input end; the vacuum tank loading equipment is mainly used for providing external load for a driving mechanism for carrying out vacuum test, and can acquire parameters such as load moment, rotating speed and the like of an output end. The vacuum tank driving device includes a vacuum tank and a driving device, and the vacuum tank loading device includes a vacuum tank and a loading device. During the installation process, the measured object needs to be installed in a vacuum tank and connected with a driving device or a loading device. If the vacuum test needs to provide driving and loading conditions for the tested object in the vacuum tank at the same time, a vacuum tank driving device and a vacuum tank loading device are generally combined into one device.
When the vacuum driving test is carried out on the tested object, the motor in the driving device provides driving force, and the output torque and the rotating speed are transmitted to the tail end output shaft through a series of transmission devices. The output end of the driving device transmits torque and rotating speed to the input end of the tested object, so that the requirement on the coaxiality between the output shaft of the driving device and the input shaft of the tested object is high, and the requirement on the alignment between the output shaft of the driving device and the input shaft of the tested object is met.
When a vacuum loading test is carried out on a tested object, a motor in the tested object provides driving force, the output torque and the output rotating speed are subjected to planetary transmission, the rotating speed is reduced at a certain transmission ratio, the torque is increased, and the output rotating speed and the output torque are transmitted to a tail end output shaft and a gear above the tail end output shaft through an electromagnetic clutch (in a power-on state). The output end of the tested object transmits torque and rotating speed to the input end of the loading device, so that the requirement on the coaxiality between the output shaft of the tested object and the input shaft of the loading device is high, and the output shaft of the tested object and the input shaft of the loading device also need to be aligned.
The performance test of the tested object generally comprises a rotating speed mode and a torque mode, and if the coaxiality error between the connecting shaft of the tested object and the connecting shaft of the equipment is overlarge, on one hand, the rotating shaft of the tested object vibrates violently at a high rotating speed, the accuracy of a collected value is influenced, the test result is inaccurate, parts on the tested object are seriously damaged even, and the safety of a test platform is damaged; on the other hand, in the long-time operation process of the equipment, the vibration of the equipment can be caused by the overlarge coaxiality error, so that the bearing generates heat, and further the bearing and the coupler on the equipment are damaged. Therefore, the coaxiality between the connecting shaft of the object to be measured and the connecting shaft of the device needs to be measured and corrected, and the deviation is adjusted to be within an allowable range.
In a vacuum test environment, a switching port on a vacuum tank is required to be connected between a tested object and equipment, the switching port is generally provided with a sealing element and is fixedly installed on a tank body of the vacuum tank, one end of the sealing element in the vacuum tank is connected with the tested object, and one end of the sealing element outside the vacuum tank is connected with the equipment. In practical cases, in order to facilitate the vacuum test, the coaxiality between the sealing member and the device connecting shaft is generally directly ensured in accordance with the mounting dimension, and the coaxiality between the sealing member and the device connecting shaft needs to be measured and corrected. In addition, under the working condition of simultaneously providing driving and loading for the measured object in the vacuum tank, the coaxiality of the key connection position on the transmission link of the whole device needs to be further verified. To facilitate handling and maintenance of the apparatus, the apparatus is usually disconnected from the seal on the vacuum tank when the object to be tested is not subjected to a vacuum test.
At present, at the in-process of the axiality between adjusting equipment connecting axle and the sealing member, artificially through the whole equipment of jack jacking come the operating height of adjusting equipment usually, adjust the horizontal work position of equipment through removing whole equipment in the horizontal direction, the adjustment degree of difficulty is big, waste time and energy, and hardly finely tune to when carrying out the axiality between equipment connecting axle and the sealing member and adjust the work, efficiency is lower.
