Description
技术领域technical field
本发明涉及电机零件检测设备技术领域，具体涉及一种转轴圆跳动检测装置。The invention relates to the technical field of motor parts detection equipment, in particular to a detection device for circular runout of a rotating shaft.
背景技术Background technique
转轴作为电机内部重要的旋转部件，其加工精度对电机振动、噪音及使用寿命有较大影响。其中，转轴上各表面的圆跳动是衡量加工精度及同轴度的重要指标，目前的检测手段是靠车床来进行测量。如图1所示，现有的检测装置包括车床、卡盘、卡爪及测量机构，卡盘与车床的侧壁活动连接，卡盘能够在竖直面内做圆周运动，卡盘与卡爪连接，卡爪能够沿径向松夹，卡爪用于将转轴的端部固定，转轴跟随卡爪和卡盘作旋转运动，通过测量机构检测转轴各表面的圆跳动。The rotating shaft is an important rotating part inside the motor, and its machining accuracy has a great influence on the vibration, noise and service life of the motor. Among them, the circular runout of each surface on the rotating shaft is an important index to measure the machining accuracy and coaxiality. The current detection method is to measure by a lathe. As shown in Figure 1, the existing detection device includes a lathe, a chuck, jaws and a measuring mechanism. Connected, the claws can be loosened in the radial direction, and the claws are used to fix the end of the rotating shaft. The rotating shaft follows the claws and the chuck for rotational movement, and the circular runout of each surface of the rotating shaft is detected by the measuring mechanism.
利用车床测量转轴的圆跳动时，无法将要测量的部位一次测量完成，需要二次装夹才能测量完所有部位，工作效率低。同时，车床属于加工设备，不是检测设备，其费用昂贵，采用机床进行转轴的圆跳动检测容易造成机床的损耗，降低机床的使用寿命。When using a lathe to measure the circular runout of the rotating shaft, the parts to be measured cannot be measured at one time, and all parts need to be clamped twice to measure all the parts, and the work efficiency is low. At the same time, the lathe belongs to the processing equipment, not the testing equipment, and its cost is expensive. Using the machine tool to detect the circular runout of the rotating shaft will easily cause the loss of the machine tool and reduce the service life of the machine tool.
