Description
Technical field
This utility model is related to feed handoff technique field, is based particularly on the many feeds of high accuracy and automatically changes feedback system
Guiding rail mechanism.
Background technology
Most of radar systems all only have the fixing feed of single or multiple feeds at present.Feedback many feeds thunder can certainly be moved
The system of reaching has the features such as radar system resource utilization is high, detectivity is strong, therefore has excellent very well in some particular cases
Gesture.Many feeds automatically change the key equipment that feedback system is this kind of radar system, and it can will need the feedback of work as needed automatically
Source shifts at focal position, changes the Focus accuracy after feedback and repeats the performance that Focus accuracy decides whole radar system.At present
In " design of large-scale radio telescope many feeds switching mechanism " that in domestic disclosed data, middle electric 54 Wang Yu wise man is write
Elaborate a kind of rotation Huan Kui mechanism.
During changing feedback, it is a very important step that feed focuses, and Focus accuracy decides whole radar system
Performance.Traditional guiding rail mechanism adopts high precision ball line slideway bad due to its corrosion resistance mostly, high cost, week
Phase is long, causes the anti-wear performance of ball line slideway poor, and under long-time use, less stable.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides the base that a kind of wearability is good and stability is high
Automatically change the guiding rail mechanism of feedback system in the many feeds of high accuracy.
The purpose of this utility model is achieved through the following technical solutions: automatically changes feedback system based on the many feeds of high accuracy
Guiding rail mechanism, the many feeds of described high accuracy automatically change feedback system and include fixed cylinder and moving cylinder, and moving cylinder is set with
In the outside of fixed cylinder, and moving cylinder can be slided with respect to fixed cylinder, and the lateral wall of described fixed cylinder vertically sets
It is equipped with multiple guide rails assembling boss, the installation surface of multiple guide rails assembling boss is located in same perpendicular, and guide rails assembling is convex
Four guide rails vertically are installed with platform, the inwall of described moving cylinder are fixed with multiple slide blocks, slide block with lead
Rail is slidably matched, and is additionally provided with wearing layer between slide block and the contact surface of guide rail.
Further, the cross section of described slide block is l type structure.
Further, described wearing layer is soft PTFE ribbon.
Further, the side wall of described fixed cylinder and moving cylinder is equipped with lightening hole, lightening hole passes through screw solid
Surely there is cover plate.
This utility model has the advantage that
1st, this utility model is used as guidance set, and the contact surface in guide rail and slide block by line slideway and slide block cooperation
Between wearing layer is set, both are used in combination and remain the low advantage of higher abrasion resistance, coefficient of friction, it is to avoid its dimensionally stable
Property difference shortcoming it is ensured that the overall performance of slide block.
2nd, multiple guide rails assembling boss are arranged on the side wall of fixed cylinder, using guide rails assembling boss as the installation base of guide rail
Accurate so that the working (finishing) area when processing reference for installation is little, flatness is easily guaranteed that, and reduces machining period, saves equipment
Manufacturing cost.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the fit structure schematic diagram of guide rail and slide block；
In figure: 1- fixed cylinder, 2- moving cylinder, 3- guide rails assembling boss, 4- guide rail, 5- slide block, 6- wearing layer.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described, but protection domain of the present utility model is not limited to
Described below.
As shown in figure 1, automatically change the guiding rail mechanism of feedback system based on the many feeds of high accuracy, described high accuracy is many
Feed automatically changes feedback system and includes fixed cylinder 1 and moving cylinder 2, and moving cylinder 2 is set in the outside of fixed cylinder 1, and moving cylinder 2 energy
Enough slide with respect to fixed cylinder 1, the lateral wall of described fixed cylinder 1 is vertically provided with multiple guide rails assembling boss 3, many
The installation surface of individual guide rails assembling boss 3 is located in same perpendicular, guide rails assembling boss 3 is installed with four edges perpendicular
Nogata to guide rail 4, the inwall of described moving cylinder 2 is fixed with multiple slide blocks 5, slide block 5 is slidably matched with guide rail 4, in slide block 5
It is additionally provided with wearing layer 6 and the contact surface of guide rail 4 between.
As shown in Fig. 2 the cross section of described slide block 5 is l type structure, the bottom surface of guide rail 4 and side and slide block 5
Two medial surface align respectively, and are provided with wearing layer 6 between guide rail 4 surface relative with slide block 5, in the present embodiment
In, preferably, described wearing layer 6 is soft PTFE ribbon, politef resistant of high or low temperature is good, wearability is good,
Coefficient of friction is low, and guide rail 4 and slide block 5 all using 4cr13 rustless steel as main body, its good, corrosion resistance of rigidity is good, machinability
Good, both are used in combination and remain the advantage that PTFE anti-wear is good, coefficient of friction is low, it is to avoid its poor dimensional stability
Shortcoming it is ensured that the overall performance of slide block.
It is equipped with lightening hole, lightening hole not only can mitigate overall weight on the side wall of described fixed cylinder 1 and moving cylinder 2,
It is alternatively arranged as service hatch, lightening hole is fixed with cover plate by screw, cover plate can be taken off in maintenance after knockout screw, not tie up
When repairing, lightening hole is sealed by cover plate, is suitable for various adverse circumstances.
