In addition, for convenience of representation, in the drawings, when the measuring board is used as a square, the main board is schematically represented as a rectangle.
The working process of the utility model is as follows:
the scheme is used for detecting the installation position when the brake is installed on the inclined plane of the motor base. When the brake is installed on the inclined plane of the motor base, the brake is well matched with the base, so that the bolt holes are required to be perpendicular to the inclined plane and preferably have equal depth; in addition, in order to make the friction body of the brake well contact with the motor shaft, it should also be ensured that the opening position on the base bevel corresponds to the motor shaft, i.e. the motor shaft axis should be located on the perpendicular bisector of the base bevel.
When the detection tool is adopted for detection:
firstly, detecting a bolt hole on a base; screwing the measuring pin into the screw hole of the base until the measuring pin cannot rotate, namely the measuring pin (or a limit column at the lower part of the measuring pin) is at the bottom; as shown in fig. 1, the tail plate of the detection plate is used for leaning against the machine base, the main plate is leaning against the measuring pin, the vertical condition of the main plate is checked, and meanwhile, the external height of the measuring pin can be measured by utilizing scale marks on the main plate so as to evaluate the depth of four bolt holes; and after the inspection, the angle is changed to continue the inspection, one is inspected, and the rest bolt holes are inspected in the same way. After the inspection, the relative positions between the adjacent three measuring pins are inspected in turn by using the right angles of the inner sides of the main board and the tail board, namely, whether the angles formed by the adjacent three measuring pins are right angles or not, and particularly, see fig. 2.
Secondly, detecting the position deviation of the machine base and the motor shaft; referring to fig. 3 and 4, the main board is placed on the stand, the bolt holes on the main board are aligned with the bolt holes on the stand (narrow sides), the main board is fixed on the stand through bolts, the edge of the stand is positioned in the middle of the depth gauge clamping groove, and data are read out and recorded through scale marks; the depth gauge body is propped against the inner side of the depth gauge clamping groove of the main board, the vernier measuring surface of the depth gauge is attached to the main board, and the bottom of the depth gauge body is contacted with the shaft surface of the motor shaft, so that the depth value is measured. And after the measurement is finished, the main board is detached and the rest group of data is measured. After the measurement is finished, comparing the edge position data and the depth data of the machine base, thereby judging whether the opening position of the machine base and the corresponding position of the motor shaft meet the requirements.

hole site verticality detection, namely screwing a long pin into a screw hole to be detected of the machine base, and enabling the bottom end of the long pin to be pressed against the bottom of the screw hole to be detected of the machine base; and detecting verticality of the measuring plate in the transverse direction and the longitudinal direction on one screw hole, and judging that the measuring plate meets the design value.
Hole position degree detection, namely dismantling a long pin and installing four short pins; and measuring the position degree of the short pin and the perpendicularity between the screw holes in two adjacent longitudinal and transverse directions, and obtaining the qualified product.
And detecting hole site symmetry, removing the unused short pins, and mounting the main board on the mounting surface of the brake to be tested of the stand through one short pin. And installing a screw at the notch of the main board, tightly attaching the main board to the screw in the measuring direction, fixing the main board by the screw, propping the depth gauge body against the inner side of the groove of the main board, attaching the measuring surface of the vernier of the depth gauge to the main board, and contacting the bottom of the depth gauge body with the shaft surface of the machine base so as to measure the depth value. And removing the screw, taking down the main board, turning over the main board by 180 degrees, and measuring a depth value corresponding to the screw hole on the machine base opposite to the measured screw hole of the machine base. And comparing the results of the two measurements, and if the measurement deviation is smaller than the design value, the installation hole position of the base brake accords with the symmetry requirement.
