Embodiment Construction
[0023] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0024] Such as figure 1 As shown, the present invention is a jig for measuring the runout rate of a bearing, which includes a movable outer frame, a sensor assembly installed on the movable outer frame, and a bearing fixing assembly installed in the middle of the movable outer frame. The bearing fixing assembly includes a The base is connected with a fixed rod for fixing the inner frame of the bearing through the motor, and a support frame for installing the movable outer frame is also connected to the base;
[0025] The movable outer frame includes an X-axis direction outer frame and a Y-axis direction outer frame, wherein the support frame includes two symm...

The invention discloses a bearing run-out rate measurement clamp. The bearing run-out rate measurement clamp mainly comprises an X axis direction outer frame and a Y axis direction outer frame. The Yaxis direction outer frame is installed on a support frame of a pedestal and can move along a Y axis direction and along the support frame. The X axis direction outer frame is installed on the Y axisdirection outer frame and can perform a reciprocating motion in the X axis direction along the Y axis direction outer frame. A bearing clamping mechanism is installed inside the Y axis direction outerframe in order to realize clamping of the bearing outer frame. A top pressure fixing mechanism comprises a top pressure housing connected to a screw in a rotation manner. An ejection plate is connected to the top pressure housing in a sliding manner. The end of the screw is in contact with the back of the ejection plate. The front surface of the ejection plate is elastically connected to the other side of the top pressure housing. An ejection rod array is arranged in the front side of the ejection plate. The ejection rods penetrate through the top pressure housing and project out to contact with the bearing. A fixed rod is arranged on the pedestal for driving the bearing in order to make the bearing outer frame deflect under driving of the bearing inner frame.
Description
technical field [0001] The invention relates to a jig for measuring the beating rate of a bearing, which belongs to the field of bearing quality inspection equipment. Background technique [0002] In the production process of some high-precision bearings, it is generally necessary to carry out relevant inspections on the bearings before leaving the factory, such as: when the bearing rotates, the coaxiality of the bearing inner frame and outer frame when the bearing rotates, and the inner frame of the bearing when the bearing rotates Yaw rate, these parameters will greatly affect the stability of the bearing during rotation and the coaxiality during transmission. If the above parameters are not measured, the entire transmission system will have a certain degree of circular runout when used. The vibration of the transmission system affects the stability of the system. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overc...
