[0025] The utility model provides Figures 1 to 6 An automatic detection and positioning mechanism for an instrument is shown, comprising:
[0026] The testing platform 1 has a support leg 20 fixedly provided at each of the four corners of the bottom end of the testing platform 1.

[0027] Two first clamping plates 3, a connecting plate 4 is fixed on the top of the first clamping plate 3, both ends of the two connecting plates 4 extend into the four first communicating ports 6 respectively, a first adjustment component is provided between the bottom end of the first clamping plate 3 and the top of the testing platform 1, two second clamping plates 5 are provided on the top of the testing platform 1, the two second clamping plates 5 are respectively provided on the front and rear sides of the two first clamping plates 3, the two ends of the two second clamping plates 5 respectively pass through the four second communicating ports 7, and a second adjustment component is provided between the second clamping plate 5 and the top of the testing platform 1.
[0028] The first adjustment component includes two first slide grooves 8 opened at the top of the detection platform 1, and a first slider 9 is provided inside the first slide groove 8. The top of the two first sliders 9 are fixedly connected to the bottom ends of the two first clamping plates 3 respectively. A first bidirectional screw rod 10 is provided inside the two first slide grooves 8, and the two ends of the first bidirectional screw rod 10 pass through the two first sliders 9 respectively. The first bidirectional screw rod 10 and the two ends inside the first slide groove 8 are both rotationally connected, and the first bidirectional screw rod 10 and the two first sliders 9 are both threadedly connected and the thread directions are opposite. A first motor 11 is fixedly provided on one side of the detection platform 1, and one end of the first bidirectional screw rod 10 is fixedly connected to the output shaft of the first motor 11.
[0029] The second adjustment component includes two second slide grooves 12 opened at the top of the detection platform 1, which are vertically distributed between the two second slide grooves 12 and the two first slide grooves 8. A second slider 13 is provided inside the second slide groove 12, and the tops of the two second sliders 13 are fixedly connected to the bottom ends of the two second clamping plates 5 respectively. A second bidirectional screw rod 14 is provided inside the two second slide grooves 12, and the two ends of the second bidirectional screw rod 14 pass through the two second sliders 13 respectively. The second bidirectional screw rod 14 and the two ends inside the second slide groove 12 are both rotationally connected, and the second bidirectional screw rod 14 and the two second sliders 13 are both threadedly connected and the thread directions are opposite. A second motor 15 is fixedly provided at the front end of the detection platform 1, and one end of the second bidirectional screw rod 14 is fixedly connected to the output shaft of the second motor 15.
[0030] A first rubber pad 16 is fixed on the inner side of the first clamping plate 3, and a second rubber pad 17 is fixed on the middle inner side of the second clamping plate 5. A pressure sensor 18 is embedded in the middle inner side of the first clamping plate 3 and the middle inner side of the second clamping plate 5. The four pressure sensors 18 are respectively arranged on the inner sides of the two first rubber pads 16 and the two second rubber pads 17. A controller 19 is fixed on a corner at the front end of the detection platform 1. The pressure sensor 18 is connected to the input end and the output end of the controller 19 respectively with the first motor 11 and the second motor 15.
[0031] Place the instrument on the top of the test bench 1 between the two first clamping plates 3 and the two second clamping plates 5, start the first motor 11, and the output shaft of the first motor 11 drives the first bidirectional screw 10 to rotate. Since the first bidirectional screw 10 is threadedly connected to the first slider 9, the two first sliders 9 approach each other as the first bidirectional screw 10 rotates, and the two first sliders 9 drive the two first clamping plates 3 to approach each other. The two first clamping plates 3 will drive the two first rubber pads 16 to clamp and fix the instrument. Similarly, start the second motor 15, and the output shaft of the second motor 15 drives the second bidirectional screw 14 to rotate. Since the second bidirectional screw 14 is threadedly connected to the second slider 13 Therefore, the two second sliders 13 approach each other as the second bidirectional screw 14 rotates, and the two second sliders 13 drive the two second clamping plates 5 approach each other, and the two second clamping plates 5 will drive the two second rubber pads 17 to clamp and fix the instrument. When the two first rubber pads 16 and the two second rubber pads 17 are squeezed around the instrument, the pressure sensor 18 will receive pressure. At this time, the pressure sensor 18 transmits a signal to the controller 19, and the controller 19 controls the first motor 11 and the second motor 15 to stop, so that the instrument can be pushed and clamped in the center of the test platform 1. The detection structure is located at the top of the center of the test platform 1, so that the instrument can be tested.
[0032] The utility model uses two first clamping plates 3 and two second clamping plates 5 to push the instrument to move and position the instrument at the center of the top of the test table 1, so that the instrument can be positioned and fixed more accurately, and no manual adjustment is required, so that the positioning and clamping process of the instrument is relatively simple and convenient, and the positioning and fixing efficiency is high. The multiple pressure sensors 18 can detect the extrusion force during the clamping process, which can prevent the clamping process from damaging the instrument. This embodiment specifically solves the problem that when the instrument is tested and fixed in the prior art, most of them use two plates to clamp and fix the instrument in the middle from both sides of the instrument, which makes it impossible to adjust the front and rear position of the instrument and cannot be positioned in the middle position of the device. Therefore, it is necessary to adjust the front and rear position of the instrument before clamping, which makes the clamping and positioning process of the instrument more troublesome.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
