[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0024] like Figure 1-5 As shown, a gas sensor incident angle test tool is characterized in that it includes:

[0025] A test base 1, one end of which has a stepped rotation mounting hole 14, and the other end of the test base 1 is mounted with a mounting seat 12;

[0026] A left and right steering stepper motor 13, which is mounted on the test base 1 below the rotating mounting hole 14;

[0027] A rotating assembly connected to the left and right steering stepping motors 13;

[0028] A launch assembly connected to the mounting base 12;

[0029] The receiving end of the rotating assembly and the transmitting end of the transmitting assembly are located on the same straight line.

[0030] Furthermore, the rotating assembly includes a rotating disk 2, a support column 21, and a left and right steering platform 22. The rotating disk 2 cooperates with the rotating mounting hole 14 and is connected to the left and right stepper motors. The support column 21 is vertically fixed on the rotating disk 2. The left and right steering platform 22 is fixed above the support column 21. A pitch steering stepper motor 23 is connected to one side of the left and right steering platform 22. A pitch steering platform 24 connected to the pitch steering stepper motor 23 is rotatably connected to the left and right steering platform 22. The pitch steering platform 24 is concave and has a plug-in slot on the edge. The sensor adapter plate 25 is connected to the pitch packing platform through the plug-in slot. The sensor adapter plate 25 can be replaced according to the sensor model. The left and right angles are adjusted by connecting the left and right steering stepper motor 13 to the rotating plate. The pitch steering stepper motor 23 is connected to the pitch steering platform 24 to adjust the pitch angle, so as to provide for subsequent testing of signal strengths at different angles.

[0031] Furthermore, the transmitting assembly includes a sensor bracket 31, a transmitting end sensor 37 and a distance adjustment bracket 34. The lower end of the sensor bracket 31 has a T-shaped base 32 connected and fixed to the mounting seat 12. The distance adjustment bracket 34 is fixed to the upper end of the sensor bracket 31. A sensor mounting seat 36 is fixed to the front end of the distance adjustment bracket 34. The transmitting end sensor 37 is fixed on the sensor mounting seat 36.

[0032] Furthermore, the sensor bracket 31 has a horizontal crossbar 33 at its upper end, the distance adjustment bracket 34 is mounted on the horizontal crossbar 33 and has a long strip-shaped adjustment slot 38, and a fixing screw 35 is provided between the distance adjustment bracket 34 and the horizontal crossbar 33 through the adjustment slot 38. By changing the position of the distance adjustment bracket 34 on the horizontal crossbar 33, the shooting distance can be adjusted by tightening the fixing screw 35.

[0033] Furthermore, a cylindrical foot 11 is provided at the lower end of the test base 1 for stabilization.

[0034] Furthermore, a receiving end sensor 26 is installed on the sensor adapter board 25 .

[0035] The sensor beam distance of this test fixture can be adjusted arbitrarily between 2cm-13cm. The signal test angle is controlled by the left and right steering stepper motor 13 and the pitch steering stepper motor 23, eliminating manual adjustment and achieving precise angles. Due to the use of automated adjustment testing, the fixture can be placed in a temperature-controlled oven to perform testing at a specified temperature. Due to the use of motor-driven angle testing, the angles in both directions can be set very finely. After turning to an angle, more comprehensive data can be collected through computer recording, and a 3D emission angle diagram of the sensor can be drawn through software.

[0036] Under the premise of a predetermined test distance, the transmitting end sensor 37 and the receiving end sensor are fixed on the workpiece position, and the two sensors are respectively connected to the oscilloscope and the signal source end. Through the micro-adjustment control of the left and right steering stepper motor 13 and the pitch steering stepper motor 23, the transmitting and receiving signals within the pitch angle and left and right angle range can be tested. Through data collection at each angle, the data can be statistically analyzed to obtain the effective transmitting angle of the sensor and the signal strength value at each angle.

[0037] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0038] The technical solutions in the above embodiments have clearly and completely described the contents of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
