Embodiment Construction
[0030] A method and device for measuring the height of the lock of the outer ring of the miniature bearing of the present invention will be further described below in conjunction with specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the implementation Examples are not intended to limit the present invention.
[0031] Measuring device for the height of the lock of the outer ring of the miniature bearing, such as figure 1 and Figure 4 As shown, it includes a torsion spring meter 1, a base 2, and a column 3 vertically fixed on the base 2. The base 2 is provided with a moving mechanism for fixing the outer ring of the bearing under test and capable of reciprocating translation. The translation path of the moving mechanism is the same as that of the column 3. It is perpendicular to each other, and it is characterized in that: the column 3 is covered with a tail plate 4, the outer peripheral surface of the tail ...

The invention discloses a miniature bearing outer ring locking notch height measuring device and measuring method. The device comprises a torsion spring meter, a base and a stand column, the base is provided with a moving mechanism which is used for fixing an outer ring of a measured bearing and can achieve reciprocating translation, the stand column is sleeved with a tail board, the peripheral face of the tail board is provided with a fastening screw fastened on the stand column, and the tail board is provided with a dividing disc; the torsion spring meter is installed on the dividing disc through a position adjusting mechanism and provided with a measuring claw; a certain included angle is formed between the measuring claw and the outer ring of the measured bearing by adjusting the fixed position of the dividing disc on the stand column through the fastening screw and adjusting the rotation angle of the dividing disc in the vertical direction, and the measuring claw can enter a channel of the outer ring of the measured bearing to conduct measurement by adjusting the torsion spring meter through the position adjusting mechanism to drive the measuring claw to rotate. The device can stably and reliably measure the height of a locking notch of the outer ring and reduce measuring errors and is especially suitable for detecting the height of the locking notch of the miniature bearing outer ring with the outer diameter size smaller than 5 mm.
Description
technical field [0001] The invention relates to the field of a miniature bearing detection method and a detection device thereof, in particular to a measurement device and a measurement method for the locking height of the outer ring of a miniature bearing. Background technique [0002] Due to the limitation of the assembly size of the main engine, the bearings used in many working conditions have to use miniature bearings. In addition to the influence of factors such as actual force, the bearings used must be angular contact ball bearings. Since the bearing used is an angular contact ball bearing, a slope needs to be ground on the inner or outer ring, and the angle and height of the slope have strict requirements. Generally, the detection of the lock is carried out with a dial indicator. Point the probe of the dial indicator to the maximum diameter of the bearing ring. At this time, adjust the dial of the dial indicator to zero, and then drive the dial indicator through the...
