[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1: See Figures 1 to 4 As shown, a vibration detection installation structure of an angular displacement sensor includes an angular displacement sensor 1, wherein the angular displacement sensor 1 is installed on a vibrator via a vibration base plate 2;

[0030] A positioning hole 3 matching the angular displacement sensor 1 is provided in the middle of the vibration base plate 2, the rear end of the angular displacement sensor 1 is inserted into the positioning hole 3, and an annular groove 4 is provided on the outer surface of the front end of the angular displacement sensor, and the annular groove 4 is arranged outside the front side of the positioning hole 3;

[0031] At least two screw holes 5 are evenly distributed in an annular manner on the front end surface of the vibration base plate 2 outside the positioning hole 3;

[0032] At least two pressing pieces 6 are also provided, the inner end of each pressing piece 6 is inserted into the annular groove 4, the rear side surface of the outer end of the pressing piece 6 is against the front end surface of the vibration base plate 2, and each pressing piece 6 is provided with a connecting bolt 7, the rear end of the connecting bolt 7 is screwed to one of the screw holes 5, and the connecting bolt 7 and the pressing piece 6 limit the angular displacement sensor 1 in the positioning hole 3.

[0033] There are four screw holes, which are arranged on the front side of the vibration base plate outside the positioning hole, and there are also four pressing pieces.

[0034] In this embodiment, the vibration base plate is installed on the vibrator (not shown in the figure of the vibrator), and the vibration base plate can be connected to the vibrator by bolts or welding, and the vibration of the vibrator can be directly transmitted to the vibration base plate. When detection is required, the pressing piece is not installed first, and then the rear end of the angular displacement sensor is inserted into the positioning hole, and the rear end of the angular displacement sensor is against the rear end surface of the positioning hole (or the rear end of the angular displacement sensor is in contact with the vibrator). Among them, the outer surface of the angular displacement sensor is in contact with the inner surface of the positioning hole, and then the inner end of the pressing piece is inserted into the annular groove, and then the connecting bolt and the screw hole are connected, so as to realize the connection between the pressing piece and the vibration base plate. In this process, since the rear side surface of the outer end of the pressing piece will be against the front side surface of the vibration base plate, and its inner end is against the annular groove, the angular displacement sensor is limited, so that when the vibrator vibrates, the vibration force is directly transmitted to the angular displacement sensor through the vibration base plate, so as to perform vibration test on the angular displacement sensor. In this way, the installation efficiency of the angular displacement sensor is high, and the testing convenience and accuracy are also high. When disassembling, it is only necessary to separate the connecting bolts and the vibration base plate, and then the pressing piece can be removed from the annular groove, thereby realizing quick disassembly.

[0035] The cross section of the annular groove is an arc surface, and the inner end of the pressing piece is an arc connecting surface, and the arc connecting surface matches the annular groove. In this way, the four pressing pieces can be pressed against the annular groove, thereby realizing accurate positioning of the angular displacement sensor without shaking and good stability.

[0036] See also Figures 2 to 4 As shown, the front end of the connecting bolt 7 is provided with a screw head, and the screw head is arranged at the front side of the pressing piece 6. A washer 8 is sleeved on the connecting bolt 7, and the washer 8 is arranged between the screw head and the pressing piece 6. Among them, the size of the washer is larger than the size of the screw head. By setting the washer, the contact area between the screw head and the pressing piece is increased, thereby ensuring that the connecting bolt can stably lock the pressing piece on the vibration base plate.

[0037] See also Figures 2 to 4As shown, at least two grooves 9 are evenly distributed in an annular manner on the front end surface of the vibration base plate 2 outside the positioning hole 3, and the inner end of each groove 9 is connected to the positioning hole 3. The number of the grooves 9 matches the number of the screw holes 5. Each screw hole 5 is arranged in one groove 9, and the rear side surface of the outer end of the presser 6 abuts against the rear side wall of the groove 9. In this embodiment, there are four grooves, and the length of the groove is greater than the length of the presser.

[0038] The pressing member 6 includes a pressing plate 10 and a pad 11 . The inner end of the pressing plate 10 is inserted into the annular groove 4 , the outer end of the pressing plate 10 is connected to the front end of the pad 11 , and the rear end of the pad 11 abuts against the rear side wall of the groove 9 .

[0039] There is a distance between the rear end surface of the pressing plate 10 and the rear side wall of the groove 9 .

[0040] The pressure plate 10 is provided with a through hole 12 , and the rear end of the connecting bolt 7 passes through the through hole 12 and is screwed to the screw hole 5 .

[0041] In this embodiment, the width of the groove matches the width of the pad, so that after the angular displacement sensor is installed in the positioning block, the pad is then placed in the groove, close to the outer end of the groove. At this time, there is a certain distance between the inner end of the pressure plate and the angular displacement sensor, and then the pad is moved inward along the groove so that the inner end of the pressure plate is inserted into the annular groove. When the inner end of the pressure plate is against the inner surface of the annular groove, the through hole will be opposite to the screw hole, and then the connecting bolt is inserted into the through hole and the screw hole and screwed until the connecting bolt is locked. The pressing piece and the vibration base plate can be locked, so that the angular displacement sensor can be axially limited by the pressing piece, so that when the angular displacement sensor is undergoing vibration testing, it will not fall off and will always be in contact with the vibration base plate, thereby ensuring the accuracy and stability of the detection.
