Please refer to fig. 1, fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6.
The radial support mechanism for seeker adjustment in this embodiment includes a radial support assembly 20 and a base 30.
The base 30 is an L-shaped structure, a bearing hole connected with the tail part of the seeker to be debugged is formed in the vertical surface of the base 30, and the tail part of the seeker to be debugged can be installed in the bearing hole and rotates relative to the base 30; the bottom of the radial support component 20 is fixedly arranged on the bottom surface of the base 30 by using a screw 40, and the normal line of the bottom surface of the base 30 at the installation position of the radial support component 20 is vertically intersected with the axis of the bearing hole; the top of the radial support assembly 20 supports the seeker 10 as it rotates relative to the base 30. If the radial support component 20 is not used, the seeker 10 is in a cantilever installation mode, large deformation is generated due to self weight, the rotation precision is affected, and after the radial support component 20 is used, the seeker 10 is changed into two-end support, and the rotation precision can be guaranteed. The mounting holes of the base 30 for mounting the radial support assembly 20 are designed into multiple groups, and the mounting position of the radial support assembly 20 can be adjusted along the direction parallel to the axis of the bearing hole according to the difference of the length and the weight distribution of the seeker 10, so as to achieve the optimal supporting effect.
The radial support assembly 20 includes a roller 21, a roller shaft 22, a flexible bracket 23, a first stud 24, a countersunk screw 25, an adjustment nut 26, a second stud 27, a roller retainer 28, and a nut 29. The radial support assembly 20 supports the guide head 10 by means of rollers 21 mounted on top.
The flexible support 23 has two symmetrical arms, and the roller 21 is fixed on the arm of the flexible support 23 through the roller shaft 22 and the roller retainer 28. The outer wall of the roller 21 is made of high polymer materials, so that the abrasion of the roller 21 to the outer wall of the guide head 10 can be reduced. The rolling bearing is arranged in the middle of the roller 21, the outer wall of the roller 21 is connected with the outer ring of the rolling bearing in a gluing mode, two ends of the inner ring of the rolling bearing are respectively pressed by the roller shaft 22 and the roller retainer ring 28, the roller 21 can freely rotate around the roller shaft 22, so that the radial support assembly 20 is guaranteed to generate rolling friction on the seeker 10 when supporting the seeker 10, and the abrasion of the outer wall of the seeker 10 can be reduced.
The roller shaft 22 passes through a circular hole in the flexible support 23, and the roller 21 is mounted on the flexible support 23, and the roller 21 can rotate relative to the flexible support 23 but cannot move in the axial direction. The tail part of the roller shaft 22 is provided with threads and is fastened by a nut 29; the head of the roller shaft 22 is designed to be non-cylindrical and can be inserted into a corresponding groove of the flexible bracket 23, the head of the roller shaft 22 can be clamped by the groove, and when the nut 29 is screwed, the roller shaft 22 cannot rotate, and no additional tool is needed.
The flexible support 23 is made of a material with a small elastic modulus, and when the radial support assembly 20 supports the seeker 10, the flexible support 23 can generate a certain deformation amount to adapt to a matching error between the radial support assembly 20 and the seeker 10.

The first stud 24 is engaged with the adjustment nut 26 by right-hand threads and the second stud 27 is engaged with the adjustment nut 26 by left-hand threads. When the adjusting nut 26 rotates clockwise, the first stud 24 and the second stud 27 move away from each other, and the flexible support 23 is driven to move away from the base 30, that is, the radial support assembly 20 increases the support height; when the adjusting nut 26 rotates counterclockwise, the first stud 24 and the second stud 27 approach each other, and the flexible support 23 is brought close to the base 30, that is, the radial support assembly 20 reduces the support height, so that the function of adjusting the support height of the radial support assembly 20 is achieved.
The upper part of the second stud 27 is designed with a D-shaped column, the section of the D-shaped column is a D-shaped section formed by cutting a part of a cylinder, and a D-shaped hole is correspondingly formed in the first stud 24 and is slightly larger than the D-shaped column. The "D" shaped post is always within the "D" shaped aperture throughout the adjustment stroke of the radial support assembly 20 being raised or lowered, and therefore the first and second studs 24, 27 are only axially movable and cannot rotate relative to each other. The middle part of the adjusting nut 26 is provided with an observation hole, which is convenient for observing the distance between the first stud 24 and the second stud 27 in the height adjusting process.
When the threads of the first stud 24, the adjusting nut 26 and the second stud 27 are designed, a proper helix angle is selected according to the friction coefficient between mutually contacted materials, and the threads can be ensured to be self-locked, so that the adjusted support height cannot be changed, and stable support is provided.
