[0010] In the above-mentioned pump cover bearing press-fit height detection device, the detection seat is provided with a mounting seat, the height gauge is eccentrically fixed on the mounting seat, and the mounting seat is provided with a mounting through hole for the probe to pass through.

[0011] In the above-mentioned pump cover bearing press-fit height detection device, a multi-level stepped structure is formed between the mounting seat, the detection seat corresponding to the detection cavity, the detection seat corresponding to the detection reference surface, and the lower convex ring.

[0012] In the above-mentioned pump cover bearing press-fit height detection device, the height gauge is a digital display height gauge. Furthermore, the mounting sleeve of the digital display height gauge is inserted into the mounting through hole and locked in place by radial bolts.

[0013] In the above-mentioned pump cover bearing press-fit height detection device, the pump cover bearing press-fit height detection device further includes a calibration mold.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-7 :

[0028] A pump cover bearing press-fit height detection device, comprising:

[0029] The workpiece to be inspected includes a pump cover 11 and a bearing 12. The pump cover 11 has an outer circumference ring 13 and an inner circumference bearing seat 14. The outer circumference ring 13 and the bearing seat 14 form a pump cover cavity 15. The bearing 12 is press-fitted into the bearing seat 14. The workpiece to be inspected is placed on the inspection table with the bearing 12 facing upward.

[0030] The detection assembly includes a detection base 21 and a height gauge 22. The bottom outer edge of the detection base 21 forms a detection reference surface 23, and the interior is provided with a detection cavity 24 for accommodating the bearing seat 14. The height gauge 22 is mounted on the detection base 21, and its probe 25 extends vertically into the detection cavity 24. During detection, the detection reference surface 23 is in contact with the outer edge ring 13 of the pump cover 11, and the probe 25 abuts against the upper end face of the bearing 12.

[0031] Comparison Appendix Figures 1 to 4The detection method and principle of this embodiment are as follows: The workpiece to be tested is placed on the testing table with the bearing 12 facing upwards, and then the testing seat 21 is placed on the workpiece to be tested. At this time, the testing reference surface 23 of the testing seat 21 is in contact with the outer edge ring 13 of the pump cover 11. The distance between the bottom end of the probe 25 and the testing reference surface 23 is the distance between the outer edge ring 13 of the pump cover 11 and the upper end face of the bearing 12. Since the distance between the upper end face of the bearing 12 and the outer edge ring 13 of the pump cover 11 is constant when the bearing 12 is assembled in place, the bearing 12 can be judged to be assembled in place by the degree of the height gauge 22.

[0032] Furthermore, in order to ensure the accuracy of the test and to facilitate the concentric placement of the test seat 21 on the workpiece to be tested, the bottom of the test seat 21 is provided with a lower convex ring 26 located between the test reference surface 23 and the test cavity 24. The outer peripheral surface of the lower convex ring 26 abuts against the outer side wall of the pump cover inner cavity 15 to form a centering structure, and a gap is left between the bottom plane of the lower convex ring 26 and the bottom of the pump cover inner cavity 15.

[0033] To facilitate the installation of the altimeter 22, a mounting base 27 is provided on the detection base 21. The altimeter 22 is eccentrically fixed on the mounting base 27, and a mounting through hole for the probe 25 to pass through is provided in the mounting base 27.

[0034] The aforementioned mounting base 27, the detection base 21 corresponding to the detection cavity 24, the detection base 21 corresponding to the detection reference surface 23, and the lower convex ring 26 form a multi-level stepped structure. The detection component with the above structure has a lower cost, is lighter, and is easier to grip.

[0035] In this embodiment, the altimeter 22 is a digital altimeter 22. Furthermore, the mounting sleeve of the digital altimeter 22 is inserted into the mounting through hole and locked in place by radial bolts.

[0036] This embodiment also provides a calibration tool for the pump cover 11 bearing 12 press-fit height detection device:

[0037] Specifically, the pump cover 11 bearing 12 press-fit height detection device also includes a calibration mold. The calibration mold includes a calibration base 31 and a calibration boss 32. The calibration base 31 is provided with a first calibration reference surface 33 that abuts against the bottom of the detection seat 21. The calibration boss 32 is provided with a second calibration reference surface 34 that abuts against the probe 25 of the height gauge 22. During calibration, the height of the detection seat 21 is the same as during the detection, and the height of the second calibration reference surface 34 on the calibration boss 32 is the same as the standard assembly height of the bearing 12.

[0038] The first verification reference surface 33 is disposed in the middle of the verification base 31, and the first verification reference surface 33 is in contact with the bottom plane of the lower convex ring 26 of the detection seat 21; furthermore, the annular plane outside the verification boss 32 forms the first verification reference surface 33.

[0039] Comparison Appendix Figures 5 to 6 The specific verification method and principle of this embodiment are as follows: The verification mold is placed on the testing table with the verification boss 32 facing upwards, and then the testing seat 21 is placed on the verification mold. At this time, the first verification reference surface 33 is in contact with the bottom plane of the lower convex ring 26 of the testing seat 21. The first verification reference surface 33 ensures that the height of the testing seat 21 is consistent during testing and verification. The standard assembly height of the bearing 12 is determined by the second verification reference surface 34. The height of the bottom end of the probe 25 is the standard height when the bearing 12 is assembled. Furthermore, the verification reading of the height gauge 22 is set to zero. During testing, the difference between the assembly height of the bearing 12 and the reference value can be determined based on the positive and negative readings of the height gauge 22.

[0040] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
