Problems solved by technology

In the processing and production process of various parts, since the precision of the direct-connected spindle of the machining center equipment is directly related to the processing quality, the machining center equipment operating at full capacity will replace a large number of direct-connected spindles for maintenance every year. The dynamic accuracy of the direct-coupled spindle cannot be tested, and it can only be installed on the equipment for testing, which affects the production efficiency of the equipment

Abstract

A straight-joint type spindle running-in testbed is disclosed. A support seat is fixed on a platform by bolts, a straight-joint spindle is mounted to the support seat, the straight-joint spindle is precisely positioned through a clamping block by using bolts, fastening bolts perform clamping fixation, a vibration sensor is installed at the bearing position of the straight-joint spindle, vibrationmonitoring is implemented on a running bearing, a drive motor lifting adjustment device is installed on a drive motor front-rear adjustment device through bolts, one end of a coupling is linked and fixed to the output shaft end of the drive motor, and the drive motor and the coupling are installed on the drive motor lifting adjustment device to carry out the running-in test on the straight-joint spindle, and the vibration frequencies at different rotational speeds are monitored by the vibration sensor. The straight-joint type spindle running-in testbed is suitable for running in various straight-joint spindles with different external dimensions, quickly and simply carries out clamping and adjustment of the straight-joint spindle, prolongs the service life of the spindle, and is applied tothe technical field of manufacturing in the modern metal part processing industry and the equipment manufacturing industry.

Description

technical field [0001] The invention relates to a direct-connected spindle running-in test bench in the technical field of modern metal parts processing industry and equipment manufacturing industry. Background technique [0002] In recent years, the direct-coupled spindle run-in test bench is a direct-coupled spindle run-in experimental device used in the maintenance process of the direct-coupled spindle of the machining center equipment. Finally, the dynamic run-in test is carried out, and the vibration, sound and heat generation of the direct-coupled spindle during operation are monitored at the same time. Moreover, the test bench is suitable for the run-in experiment of direct-coupled spindles of different models and shapes, avoiding the need for maintenance of direct-coupled spindles. It is installed on the equipment for running-in test, which ensures the maintenance quality of the main shaft, improves the service life of the main shaft, and reduces the production and o...
