One difficult point of processing technology.Since cantilever design local stiffness is weaker, in the process of the payload mounting surface of processing thereon
In, because cutting stress leads to the generation of flutter, to be difficult to ensure the flatness of payload mounting surface.
Innovative design of the present invention is a kind of for auxiliary support apparatus in cantilever flexible structure processing dressing process, and proposes
A kind of support method of adjustment, effective solution cantilever flexible structure process dressing process Flutter Problem, substantially increase and defend
The machining accuracy of star payload mounting surface.
The explanation or report for not finding technology similar to the present invention in space industry at present are also not yet collected into both at home and abroad
Similar data.
Summary of the invention
The Flutter Problem generated in dressing process is processed to solve cantilever design, the purpose of the present invention is to provide a kind of needles
To auxiliary support apparatus in cantilever flexible structure processing dressing process, and corresponding support method of adjustment is proposed, thus maximum limit
Degree eliminates the flutter in cantilever flexible structure processing dressing process, improves the machining accuracy of Satellite Payloads mounting surface.
In order to achieve the above object, the present invention provides one kind for auxiliary branch in cantilever flexible structure processing dressing process
Support arrangement, the device include: column, horizontal fixed link, rubber pad, swingle, support rod, nut, oblique fixed link.
The horizontal fixed link is located at column top surface, is connected with column, for installing support rod；
The oblique fixed link is connected with column and horizontal fixed link；
The swingle crosses support rod, and firm welding, and the height of support rod is adjusted for rotary supporting rod；
The rubber pad is by the way that glue is viscous and support bar top for protecting supporting surface reduces the impact of process
Power.
Further, the column is formed using iron casting, stands on ground, the load-carrying construction as whole device.
Further, the horizontal fixed link is connected by screw with column.
Further, the oblique fixed link is connected by screw with column and horizontal fixed link, for reinforcing horizontal fixed link
Rigidity reduces vibration.
Further, support rod design has one section of screw thread, is fixed in horizontal fixed link by nut, for to be added
Work cantilever flexible structure is supported, and reduces the flutter in process.
In order to improve the machining accuracy of Satellite Payloads mounting surface, the present invention also provides a kind of processing of flexible structure to repair
Whole auxiliary support apparatus method of adjustment, the specific steps are as follows:
Step 1: passing through downward pressure average value in finite element stimulation cantilever flexible structure process to be processed；
Step 2: calculating deflection of the rubber pad under the pressure that step 1 is calculated；
Step 3: machine tool chief axis installs dial gauge, presses table in face to be processed, dial gauge zero setting；
Step 4: adjusting support rod height, so that support rod is contacted the reverse side (Fig. 2) in face to be processed, percentage list index just has
Changed, but still in zero-bit；
Step 5: adjusting support rod makes support rod continue the deflection that ascending step 2 is calculated.
The present invention guarantees that flexible structure processes the stability of auxiliary support apparatus by big quality column, utilizes support rod pair
Face reverse side to be processed is supported, and reinforces the local stiffness of cantilever flexible structure, the elasticity of rubber pad is recycled to weaken processing
Machinery vibration in the process.In the process of adjustment auxiliary support apparatus, bearing height is accurately controlled using dial gauge, finally most
While limits eliminate flutter in cantilever flexible structure processing dressing process, the processing of Satellite Payloads mounting surface is improved
Precision.
