[0019] The present invention can be explained in more detail by the following examples, but the present invention is not limited to the following examples.

[0020] Combined with attachment Figures 1 to 3 The tooling for measuring the height of a bearing assembly comprises a height measuring instrument 1, a measuring gauge 2 and a pressure cover 5. The height measuring instrument 1 is a G906 height measuring instrument. A bearing to be measured 3 is provided on the workbench of the height measuring instrument 1. A pressure cover 5 is provided on the large end surface of the outer ring of the bearing to be measured 3. Figure 2 、 3 As shown, the gland 5 includes a gland body, a measuring limit surface 501, a crossbeam 502, a semicircular hole 503 and a measuring working surface 504. A downwardly concave measuring limit surface 501 is provided on the upper surface of the gland body, and two semicircular holes 503 penetrating to the bottom of the gland body are symmetrically provided on the measuring limit surface 501. A crossbeam 502 is provided between the two semicircular holes 503, and a measuring working surface 504 is provided under the crossbeam 502. In specific implementation, the outer shape of the gland body is any one of a circle or a polygon, wherein a circle is preferred. When it is a polygon, it is preferably a square. The flatness of the measuring limit surface 501 on the pressure cover 5 is ≤0.003mm, the flatness of the measuring working surface 504 on the pressure cover 5 is ≤0.003mm, and the parallelism of the measuring working surface 504 and the measuring limit surface 501 is ≤0.005mm. A measuring table 2 is provided above the measuring working surface 504 on the pressure cover 5. The measuring table 2 is provided on the rocker arm of the height measuring instrument 1. The measuring table pressure head 4 at the lower end of the measuring table 2 is pressed on the measuring working surface 504 to form the tooling for measuring the bearing assembly height.

[0021] During specific implementation, through the setting of the pressure cover 5, the pressure cover 5 provides appropriate pressure to ensure that the outer ring of the tested bearing 3 fits the inner component, so that the assembly height can be accurately measured, and the interference of the retainer of the tested bearing 3 on the large end face of the outer ring can be avoided. The force of the pressure cover 5 acts on the large end face of the outer ring of the tested bearing 3 to provide appropriate pressure. Both calibration and measurement act on the same position point of the pressure cover 5.

[0022] When the utility model is implemented, the specific measurement method includes the following steps:

[0023] Step 1: Zero the measuring meter:

[0024] First, select the appropriate gland 5 and standard height block according to the specifications of the bearing 3 to be measured. Then, place the standard height block and gland 5 together on the workbench of the height measuring instrument 1 to calibrate the measuring table 2 to zero. After the zeroing is completed, remove the standard height block.

[0025] Step 2: Measure the assembly height of the bearing under test:

[0026] Continue with the previous step, such as Figure 1 As shown, the bearing 3 to be measured is placed on the workbench of the height measuring instrument 1. After the measuring limit surface 501 of the pressure cover 5 is matched with the large end face and outer diameter of the outer ring of the bearing 3 to be measured, the measuring gauge pressure head 4 on the measuring gauge 2 is brought into contact with the measuring working surface 504, and the measuring gauge 2 is used to measure the assembly height.

[0027] The utility model uses the height instrument G906 and the pressure cover 5 in combination to effectively measure the assembly height of large thin-walled tapered roller bearings, providing real and reliable data for setting and adjusting process parameters in the production and processing process.
