Description

DETAILED DESCRIPTION

[0034] The following further explains this patent with reference to the accompanying drawings. However, the scope of protection of this patent is not limited to specific implementation methods. Example 1

[0035] like Figure 1 As shown, the utility model discloses an alarm angle vibration test tooling, which is used to realize target tracking measurement of the azimuth and pitch directions of an alarm product 4 under a single-axis turntable, and is characterized by comprising: a base 1, a reinforcement frame 2, and a mounting frame 3.

[0036] The mounting frame 3 is fixed to the reinforcement frame 2 by welding, and the bottom of the reinforcement frame 2 is fixed to the base 1 by welding.

[0037] The azimuth direction test positioning holes are set on the installation frame including the upper frame and the left frame; the pitch direction test positioning holes are set on the lower frame and the right frame of the installation frame.

[0038] When using, Figure 5 As shown, first, the alarm product 4 is installed on the mounting frame 3 through the azimuth direction test positioning holes and fastening screws on the mounting frame 3, and then the base 1 is installed on the single-axis turntable through the base fixing holes 5 and fastening screws. In conjunction with the test equipment, the azimuth direction tracking target test of the alarm product 4 can be realized.

[0039] like Figure 6 As shown, after the azimuth direction test is completed, the alarm product 4 is removed from the mounting frame 3, and then the alarm product 4 is installed on the mounting frame 3 through the pitch direction test positioning hole on the mounting frame 3. In conjunction with the test equipment, the pitch direction tracking target test of the alarm product 4 can be realized.

[0040] like Figure 7 As shown, under two different installation postures of the alarm product 4, the optical axis deviation accuracy of the product can be effectively guaranteed, and the tracking target test in the azimuth and pitch directions can be achieved without excessive adjustment of the state of the test equipment.
