[0002] With the rapid development of my country's economy, sophisticated electronic testing equipment such as radar, cameras, and sensors are widely used in various fields and industries to achieve detection and testing functions.

[0003] Because a single detection device has a limited detection range, and because these devices are typically fixed in place, they often have significant blind spots during operation. Therefore, it is usually necessary to install multiple detection devices in the area to be inspected, with each device inspecting the area from different angles. While this reduces the blind spots, it also increases equipment costs. In view of this, this application proposes a multi-degree-of-freedom detection fixture. Utility Model Content

The lifting assembly is used to drive the inspection device to move along the Z direction, and the first rotating assembly is used to drive the inspection device to rotate.

[0006] Specifically, the lifting assembly includes a lead screw motor, a nut seat, and a connecting plate. The body of the lead screw motor is fixed to the column, and the connecting plate is connected to the lead screw of the lead screw motor through the nut seat. The connecting plate is used to support the testing equipment.

[0007] Specifically, the first rotating assembly includes a first motor, a worm gear connected to the output shaft of the first motor, and a worm wheel connected to the worm gear.

[0008] Specifically, the tooling further includes a second rotating assembly for connecting the base and the column. The second rotating assembly includes a second motor, a first gear disposed on the output shaft of the second motor, and a second gear rotatably connected to the base. The second gear meshes with the first gear, and the column is disposed on the second gear.

[0009] Specifically, the tooling further includes a traversing assembly for connecting the lifting assembly and the first rotating assembly. The traversing assembly includes a third motor, a slider, and a guide rail. The third motor and the guide rail are mounted on the connecting plate.

[0024] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.

[0025] Furthermore, the terms "first" and "second" are used only to distinguish between different terms in description and do not have any special meaning.

[0026] like Figure 1 As shown, the multi-degree-of-freedom detection fixture of this embodiment includes a base 1, a column 2 disposed on the base 1, a lifting assembly 3 disposed on the column 2, a first rotating assembly 4 connected to the lifting assembly 3, and a detection device 5 connected to the first rotating assembly 4. The base 1 is used to connect to the ground or a platform; the lifting assembly 3 is used to drive the detection device 5 to move along the Z direction; and the first rotating assembly 4 is used to drive the detection device 5 to rotate.

[0027] By adopting the above solution, the detection device 5 of this embodiment can adjust its position in the Z-axis direction under the drive of the lifting component 3 and rotate under the drive of the first rotating component 4, which can increase the detection range of a single detection device 5. Using the tooling of this embodiment in the area to be detected can save the cost of the detection device 5 while meeting the detection requirements.

[0028] Combination Figures 1 to 3 As shown, the lifting assembly 3 in this embodiment includes a lead screw motor 31, a nut seat 32, and a connecting plate 33. The body of the lead screw motor 31 is fixed to the column 2, the connecting plate 33 is connected to the lead screw of the lead screw motor 31 via the nut seat 32, and the detection device 5 is mounted on the connecting plate 33. Furthermore, in conjunction with... Figure 1 and Figure 3 The column 2 can be composed of four plates, which are hollow. Most of the lifting assembly 3 can be set inside the column 2. One of the plates has a window for the connecting plate 33 to extend from the inside of the column 2 to the outside. The detection device 5 is set on the part of the connecting plate 33 located outside the column 2.

[0029] like Figure 4 As shown, the first rotating assembly 4 in this embodiment includes a first motor (not shown), a worm gear 41, and a worm wheel 42. The worm gear 41 is connected to the output shaft of the first motor, and the worm wheel 42 is rotatably connected to the connecting plate 33 of the lifting assembly 3 and cooperates with the worm gear 41. The detection device 5 is connected to the worm wheel 42. When the first motor drives the worm gear 41, it rotates, driving the worm wheel 42 and the detection device 5 on it, thereby achieving a precise rotational movement of the detection device 5 within ±180°.

[0030] Combination Figure 1 and Figure 5As shown, the multi-degree-of-freedom detection fixture in this embodiment also includes a second rotating component 6, which is disposed between the base 1 and the column 2, and is used to drive the column 2 to rotate 360° relative to the base 1. Specifically, the second rotating component 6 includes a second motor 61, a first gear 62, and a second gear 63. The body of the second motor 61 is fixed to the base 1, and its output shaft is connected to the first gear 62. The second gear 63 is rotatably connected to the base 1 and meshes with the first gear 62. The column 2 is disposed on the second gear 63. Preferably, the diameter of the second gear 63 is larger than the bottom area of ​​the column 2 to improve the reliability of the connection between the two. At the same time, the diameter of the second gear 63 is also larger than the diameter of the first gear 62. With the above scheme, when the second motor 61 drives, under the transmission of the first gear 62 and the second gear 63, the column 2 can achieve 360° rotation, further increasing the detection range of the detection device 5.

[0031] like Figure 4 As shown, the multi-degree-of-freedom detection fixture of this embodiment may further include a transverse component 7, which is used to connect the lifting component 3 and the first rotating component 4. Specifically, the transverse component 7 includes a third motor 71, a slider 72, and a guide rail 73. The body of the third motor 71 and the guide rail 73 are fixed to the connecting plate 33 of the lifting component 3. The output shaft of the third motor 71 and the guide rail 73 both extend horizontally. The slider 72 is connected to the output shaft of the third motor 71 and to the guide rail 73. The first rotating component 4 is disposed on the slider 72. When the third motor 71 drives the slider 72 to move linearly, it can drive the detection device 5 to move linearly in the horizontal direction, adjusting the horizontal position of the detection device 5 and further increasing the detection range of the detection device 5.

[0032] The detection device 5 in this embodiment can be one or more of radar, camera, and sensor.

[0033] The detection device 5 in this embodiment also includes a microcomputer for electrically connecting with the lifting assembly 3, the first rotating assembly 4, the second rotating assembly 6, the transverse moving assembly 7 and the detection device 5.

[0034] In summary, the method of using the multi-degree-of-freedom detection fixture in this embodiment is as follows: According to the range or position to be detected, the position and rotation angle of the detection device 5 are adjusted by one or more of the lifting component 3, the first rotating component 4, the second rotating component 6 and the transverse component 7. At the same time, the microcomputer records the data of each scanning position, and the preset parameters can be directly called in the future to realize the automated operation of the detection device 5 without manual intervention.
