Technical Field

[0001] The utility model relates to a detection device, in particular to a rotary depth detection device. Background Art

[0002] As Figure 9 shown, an installation groove 92 is provided on the part 9, and an installation hole 93 is provided at the bottom of the installation groove 92. The installation hole 93 is a stepped hole, and a washer 91 is installed at the top of the installation hole 93. After installing the washer 91, it is necessary to detect the installation height and flatness of the washer 91. Since the installation groove 92 is small, a conventional micrometer cannot be directly used for detection. Therefore, how to detect the installation height and flatness of the washer 91 is an urgent problem to be solved. Summary of the Utility Model

[0003] To solve the problem that the installation height and flatness of the above-mentioned washer cannot be detected, the utility model provides a rotary depth detection device, and the specific technical solution is as follows:

[0004] A rotary depth detection device includes a micrometer, and further includes: a detection seat provided with a detection hole and a detection column for inserting into the installation hole; a rotary device disposed in the detection hole and connected to the fixed rod of the micrometer; and a detection probe disposed on the detection rod of the micrometer.

[0005] Preferably, the rotary device includes: a thrust ball bearing disposed at the bottom of the detection hole and inserted on the detection rod; a rotary seat disposed in the detection hole and respectively connected to the thrust ball bearing and the fixed rod; and a fixing ring disposed at the top of the detection hole and movably abutted against the rotary seat.

[0006] Further, it further includes a set screw disposed on the rotary seat and pressing against the fixed rod.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The rotary depth detection device provided by the utility model uses the rotary seat to position the detection reference, and uses the rotatable micrometer to detect the installation height and flatness of the washer. The detection is convenient, simple, and has high detection efficiency. Brief Description of the Drawings

[0018] The present utility model will be further described in conjunction with the accompanying drawings.

[0019] As Figures 1 to 5 shown, a rotary depth detection device includes a micrometer 2, a detection seat 1, a rotating device and a detection probe 3. A detection hole 13 is provided at the top of the detection seat 1, and a detection column 11 is provided at the center of the bottom. The detection column 11 is matched with the mounting hole 93 and is in clearance fit, and can rotate freely in the mounting hole 93. A detection groove 12 is further provided at the bottom of the detection seat 1. The detection groove 12 communicates with the detection hole 13, and the detection column 11 is located at the center of the detection groove 12. The rotating device includes a thrust ball bearing 4, a rotating seat 5 and a fixing ring 6. The rotating seat 5 is a stepped shaft and is provided with a connection hole 53 and a screw hole 54. The screw hole 54 communicates with the connection hole 53 and is equipped with a set screw. The fixing rod 21 of the micrometer 2 is inserted into the connection hole 53 and is fixed on the rotating seat 5 through the set screw. The detection probe 3 is installed on the detection rod 22 of the micrometer 2. The detection probe 3 is located in the detection groove 12 and is arranged opposite to the washer 91. The rotating seat 5 is movably installed in the detection hole 13 and is located above the thrust ball bearing 4. The fixing ring 6 is installed at the top of the detection hole 13 through screws and is movably abutted against the shoulder of the rotating seat 5.

[0020] As Figures 6 to 9 shown, during detection, the detection column 11 is inserted into the mounting hole 93, so that the detection probe 3 abuts against the top of the washer 91. Rotate the dial of the micrometer 2 to align the pointer with the zero position, and then rotate the detection seat 1 for detection at multiple positions. When the dial of the micrometer 2 faces the side wall of the mounting groove 92, the micrometer 2 can be rotated. The micrometer 2 rotates through the rotating seat 5 and keeps the relative height of the micrometer 2 unchanged, so that the dial of the micrometer 2 faces the detector for convenient reading, realizing the rapid detection of the installation height and flatness of the washer 91. The overall structure is simple, the detection is convenient and fast.
