[0046] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. 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.

[0047] like Figure 1 and Figure 1aThe compact field source position and angle adjustment base shown, the base and the source constitute a compact field source assembly, the compact field source is installed on the compact field source position and angle adjustment base, and the compact field source assembly is fixedly installed on a plane, such as installed on the ground of a test site. The compact field source position and angle adjustment base includes a translation mechanism for realizing three translational degrees of freedom, and a rotation mechanism for realizing three rotational degrees of freedom. The translation mechanism and the rotation mechanism realize the posture adjustment of the compact field source in the six degrees of freedom directions of space through an assembly relationship. Through the compact field source assembly composed of the base and the source, the left and right, front and back, and lifting position translation adjustment of the source can be realized through simple operation, and the azimuth, pitch, and roll angle rotation adjustment of the source can be realized. The source can be accurately adjusted to the focus of the reflection surface, automatically locked when adjusted in place, and remain stable for a long time.

[0048] like Figure 2 The structural diagram of the left / right / front / back translation slide shown in the figure, the translation mechanism further includes:

[0049] The left and right translation slide 1 is used to adjust the position of the compression field source in the left and right directions;

[0050] The front and rear translation slide 2 is used to adjust the position of the compression field source in the front and rear directions;

[0051] Preferably, the left and right translation slide is installed at the bottom layer of the base, and the connection interface designed by the adjustment base and the ground is installed on the left and right translation slide 1, so that the left and right translation slide 1 can be fixedly connected to the ground by bolts. A threaded rod 12 is arranged on the left and right translation slide 1, and the threaded rod 12 is installed along the axial direction of the left and right translation slide 1. A slide 11 that can move along the threaded rod 12 is mounted on the threaded rod 12, so that the left and right position of the collapse source can be adjusted. A guide rail 13 is also installed on one side of the threaded rod 12, and the guide rail 13 passes through the slide 11. By setting the guide rail 13, the slide 11 can play a supporting role during the movement process, so that the slide 11 is more stable during the movement process. The front and rear translation slide 2 is fixedly installed on the slide 11, and the front and rear translation slide 2 is arranged perpendicular to the left and right translation slide 1, so that the front and rear position of the collapse source can be adjusted, and the six-degree-of-freedom position and angle of the collapse source 7 can be accurately adjusted to ensure that the collapse source is stable and safe during the test.

[0052] Preferably, a crank 14 is installed at one end of the threaded rod, and the front-rear translation slide 2 and the left-right translation slide 1 have the same structure.

[0053] like Figure 2aThe exploded structure diagram of the left / right / front / back translation slide shown in the figure also includes a connecting piece 15 and a distance measuring device 16 in the left / right / front / back translation slide. The connecting piece 15 is a sheet-like object with a bent shape. One end of the connecting piece 15 is connected to the distance measuring device 16, and the other end is connected to the slide 11. The distance measuring device 16 and the slide 11 are translated synchronously through the connecting piece 15, and the distance meter on the distance measuring device 16 is used to record and display the moving distance of the slide 11.

[0054] Combination Figure 2 and Figure 2a It can be seen that the left and right translation slides, front and back translation slides (as well as the vertical lifting slide to be mentioned below) all use trapezoidal screw transmission with self-locking function to achieve translational motion and self-locking. Since the trapezoidal angle is greater than the inclination angle of the screw and the torque of the trapezoidal screw is greater than the friction torque, the left and right / front and back translation slides all have good self-locking performance, and the automatic locking function can be realized when the slide is adjusted into place.

[0055] like Figure 3 The azimuth rotating slide 8 shown is used to realize the lateral movement of the compression field collapse source. The bottom surface of the azimuth rotating slide 8 is fixedly connected to the top surface of the front and rear translation slide 2, and the top surface of the azimuth rotating slide 8 is fixedly connected to the bottom surface of the vertical lifting slide 3.

[0056] The azimuth rotating slide 8 is used to realize the horizontal rotation of the source. The azimuth rotating slide 8 adopts a precision worm gear structure transmission, which can rotate in any forward and reverse direction and automatically lock when in place. By manually rotating the rotating handle at the worm input end, the worm gear can be driven to rotate to achieve the angle adjustment of the slide. There is a laser-engraved ruler on the outer periphery of the table surface of the slide, and the ruler can rotate relative to the table surface to facilitate the initial positioning and angle reading during angle adjustment.

[0057] like Figure 3a As shown, the azimuth rotating slide 8 includes a rotating table 81, a worm wheel 82, a worm 83, a stopper 84 and a motor 85. The top surface of the rotating table 81 is connected to the vertical lifting slide 3, and the bottom surface of the rotating table 81 is fixedly connected to the upper side of the worm wheel 82. The worm wheel 82 and the worm 83 are combined to form a worm gear structure. The motor 85 is connected to one end of the worm 83. The threaded end of the worm 83 meshes with the teeth on the edge of the worm wheel 82. The worm gear structure rotates under the drive of the motor 85, further driving the rotating table 81 and the vertical lifting slide 3 to rotate, thereby realizing the lateral movement of the entire compression field source position and angle adjustment base.

[0058] like Figure 4 Combined with Figure 4a , Figure 4b and Figure 4cThe vertical lifting slide 3 shown in the figure is used to adjust the vertical position of the compression field collapse source; the vertical lifting slide 3 is installed on the upper surface (i.e., the top surface) of the azimuth rotating slide 8, and the vertical lifting slide 3 and the azimuth rotating slide 8 are fixed by bolts, which can realize the up and down position lifting and adjustment of the collapse source.

[0059] The vertical lifting slide 3 includes a top surface and a bottom surface, and a folding and unfolding mechanism is arranged between the top surface and the bottom surface. The bottom surface of the vertical lifting slide is fixedly installed on the azimuth rotating slide, and the top surface of the vertical lifting slide is fixedly connected to the bottom surface of the pitch angle slide.

[0060] A folding and unfolding mechanism 36 is arranged between the top surface 31 and the bottom surface 35 of the vertical lifting slide. The bottom surface 35 of the vertical lifting slide 3 is fixedly installed on the upper side of the azimuth rotating slide 8. The top surface 31 of the vertical lifting slide 3 is fixedly connected to the bottom surface of the pitch angle slide 4. A folding and unfolding mechanism 36 is arranged between the top surface 31 and the bottom surface 35 of the vertical lifting slide 3. The folding and unfolding mechanism is used to change the distance between the bottom surface and the top surface of the vertical lifting slide.

[0061] Specifically, a screw 32 is installed on the lower surface of the top surface 31, one end of the screw is connected to the screw adjustment knob 33, the screw adjustment knob 33 is used to receive external force to move the folding mechanism 36, the folding mechanism 36 is an X-shaped structure with two folding arms, the two folding arms are folding arm 361 and folding arm 362, the folding arm 361 and the folding arm 362 intersect at the rotating shaft 363, and the two folding arms can rotate around the rotating shaft 363. Since the folding arms 361 and 362 are rotatably connected to the top surface 31 and the bottom surface 35 respectively, when the folding arms 361 and 362 rotate around the rotating shaft 363, the top surface 31 and the bottom surface 35 can be driven to move in the vertical direction. A sliding rod 34 is installed on the bottom surface 35, and the folding mechanism 36 clamps a sliding block 37. The sliding block 37 is sleeved on the sliding rod 34. When the screw adjustment knob 33 is rotated, the folding mechanism changes the distance between the top surface 31 and the bottom surface 35. The sliding block 37 slides along the sliding rod 34 as the folding mechanism 36 is unfolded, thereby realizing the change of the distance of the entire adjustment base in the vertical direction.

[0062] like Figure 5The pitch angle slide 4 shown in the figure has the function of adjusting the pitch angle to achieve the compression field collapse source. The bottom surface of the pitch angle slide is fixedly connected to the top surface of the vertical lifting slide, and the pitch angle slide includes an upper pitch angle slide and a lower pitch angle slide. The side of the upper pitch angle slide facing the lower pitch angle slide is a convex surface, and the lower pitch angle slide has a concave surface that matches the outer contour of the convex surface. The upper and lower pitch angle slides can move relative to each other along the contact surface between the convex surface and the concave surface. The bottom surface of the pitch angle slide 4 is fixedly connected to the bottom surface of the vertical lifting slide 3, and the top surface of the pitch angle slide 4 is fixedly connected to the rolling and rotating slide 6 through a fixed workpiece 5. The pitch angle slide 4 transmits the pitch action to the rolling and rotating slide 6 through the fixed workpiece.

[0063] like Figure 5a to Figure 5d As shown, relative motion can be generated between the upper pitch angle slide 41 and the lower pitch angle slide 42, and the convex surface of the upper pitch angle slide 41 and the concave surface of the lower pitch angle slide 42 form a contact surface, and the upper and lower pitch angle slides 41 and 42 can generate relative motion along the contact surface, thereby changing the angle of the pitch angle slide 4 relative to the horizontal plane. Specifically, a threaded rod 43 is provided in the middle of the lower pitch angle slide 42, and a rack 44 corresponding to the threaded rod 43 is provided in the middle of the upper pitch angle slide 41, and the engagement between the rack 44 and the threaded rod 43 enables relative motion between the upper and lower pitch angle slides 41 and 42. A push handle 45 is installed on one side of the lower pitch angle slide for pushing the lower pitch angle slide 42, so that relative motion is generated between the upper and lower pitch angle slides by external force.

[0064] like Figure 6 and Figure 6a , Figure 6b The rolling rotary slide 6 shown in the figure has the function of rotating along its axis according to the compression field source to realize rolling motion. The rolling rotary slide 6 includes a rotating connection plane 61, a worm wheel 62, a worm 63, a stopper 64 and a rotating handle 65 at the worm input end. The worm wheel 62 and the worm 63 form a worm gear structure. Under the rotation of the rotating handle 65 at the worm input end, the worm wheel 62 can rotate, thereby driving the rotating connection plane 61 and the source 7 to rotate. There is a laser engraved ruler on the periphery of the upper table surface of the rolling rotary slide 6, and the ruler can rotate relative to the table surface to facilitate the initial positioning and angle reading during angle adjustment.

[0065] like Figure 7 Combined with Figure 6 and Figure 1 , Figure 1aAs shown, a fixed workpiece 5 is passed between the rolling and rotating slide 6 and the collapse source 7, and the fixed workpiece 5 includes a horizontal plane and a vertical plane. The horizontal plane is fixedly connected to the top surface of the pitch angle slide, and the vertical plane is fixedly connected to the rolling and rotating slide, and reinforcing ribs are installed between the horizontal plane and the vertical plane.
