Detailed Description
The utility model is described in further detail below with reference to the following examples of the drawings.
As shown in the figure, a detection apparatus for detecting that the flange of the outer ring of a cylindrical roller bearing is not back gouged comprises a support, a connecting block 9, a measuring head 2 and a displacement sensor, wherein the displacement sensor in this embodiment adopts a digital display dial indicator 3, the support comprises a base 4 and a column 5, the column 5 is fixed on the base 4, the connecting block 9 is fixedly connected with the column 5, a sensor locking mechanism is arranged on the connecting block 9, the sensor locking mechanism comprises a sleeve 6 and a locking bolt 7, the sleeve 6 is fixed on the shell of the digital display dial indicator 3, the sleeve 6 vertically penetrates through the connecting block 9 downwards, the locking bolt 7 is in threaded connection with the connecting block 9 and radially abuts against the sleeve 6, so that the sleeve 6 is fixed, a hand wheel 8 is fixedly arranged on the locking bolt 7, a measuring rod 31 of the digital display dial indicator 3 penetrates through the sleeve 6, the lower end of the measuring rod 31 is fixedly connected with the measuring head 2, and a front end face 21 and a lower end face 22 of the measuring head 2 are both planar, and the lower end surface 22 of the measuring head 2 is an inclined surface, so that the measuring head 2 is in line contact with the flange 11 of the bearing outer ring 1 during detection.
In the above embodiment, since the rib 11 of the bearing outer ring 1 is generally small in thickness, the inclination angle of the lower end surface 22 of the probe 2 is preferably 5 ° ± 1 ° in order to allow the lower end surface 22 of the probe 2 to be in better contact with the rib 11.
In the above embodiment, the use method of the detection device is as follows: the standard cylindrical roller bearing outer ring is placed on the base station 4, the hand wheel 8 is screwed to enable the sleeve 6 to move up and down and enable the measuring head 2 to be in contact with the flange 11 of the standard outer ring, zeroing the digital display dial indicator 3, locking the sleeve 6 at the moment, then placing the outer ring 1 of the cylindrical roller bearing to be measured on the base platform 4, enabling the measuring head 2 to lean against the inner side of the upper end of the retaining edge 11 (namely, above the tool withdrawal groove), then slowly moving the outer ring 1 to enable the front part of the lower end of the measuring head 2 to be in line contact with the retaining edge 11, as shown in FIG. 3, the reading of the digital dial indicator 3 is observed at this time, if the height tolerance of the rib 11 is exceeded, the rib of the outer ring is determined to be unqualified in size or not to be back-gouged, and is determined to be an unqualified product, since the non-back chipping is usually discontinuous, the outer ring 1 of the bearing needs to be rotated to detect multiple points of the flange 11 during detection, so as to ensure the accuracy of detection.
The scope of the present invention includes, but is not limited to, the above embodiments, and the scope of the present invention is defined by the appended claims, and any substitutions, modifications, and improvements that may occur to those skilled in the art are intended to fall within the scope of the present invention.
