Abstract
The invention belongs to a friction reduction vibration isolation technology and relates to a sliding liner plate apparatus used in installation bracket of an avionic device. The sliding liner plate apparatus comprises: a sliding gasket, a double-sided glue film, a supporting plate, a front fixed block, a rear fixed block, a fixed screw and a rear supported plate. By using the apparatus, a pushing force needed during electronic equipment is pushed into the installation bracket can be reduced. A surface treatment result of a cabinet bottom and a supporting plate surface which are contacted during the mutual sliding of the electronic equipment can not be damaged. Buffering and isolation effects can be achieved when the electronic equipment is impacted and vibrates. By using the apparatus, rapid loading and unloading of the avionic device can be guaranteed.
Description
Technical field
The invention belongs to the antifriction vibration isolation technique, relate to a kind of slip lining device that is used for installation bracket.
Background technology
In the time of along with the avionic device standardization of products, modularization development, to the Fast Installation and the higher requirement of dismounting proposition of product, the most frequently used a kind of quick handling mode is fixed to cabinet on the installation bracket through screw locking device exactly.And existing installation bracket destroys cabinet enamelled coating and supporting plate surface-treated layer easily because skin-friction force is bigger, not only influences attractive in appearancely, and makes the tolerance variation of electronic equipment to environment.Firmly more also can cause the connector damage when electronic equipment chassis loads and unloads in addition, directly have influence on the effect that electronic equipment connects fast.Also having existing supporting plate surface is that rigidity contacts with cabinet, causes mechanical damage when being vibrated or impacting easily.
Summary of the invention
The objective of the invention is: the objective of the invention is to propose a kind of frictional force can not only reduce avionic device and on installation bracket, load and unload the time, and can carry out the device of vibration isolation protection electronic equipment chassis.
Technical scheme of the present invention is:
A kind of slip lining device that is used for installation bracket is characterized in that, comprises two liners, two two-sided glued membranes, supporting plate, preceding fixed block, back fixed block, hold-down screw, rear carrier plate.The bottom of supporting plate is a rectangle, and two sides panel beating bending is a vertical plane parallel to each other.Rear carrier plate vertically is installed on the rear portion of supporting plate.Liner is a kind of soft PTFE ribbon, and two liners are with on the parallel upper surface that is bonded in the supporting plate bottom of two two-sided glued membranes, and arranged direction is parallel with the supporting plate two sides, and is vertical with rear carrier plate, forms two smooth sliding contact planes.Liner and double faced adhesive tape film length exceed the two ends of the bottom surface of supporting plate; The part that exceeds is to the reverse side bending of supporting plate bottom; And be bonded in the reverse side of supporting plate bottom; Preceding fixed block is fixed on the lower surface of supporting plate bottom with the back fixed block, and will be tight to the liner and the double faced adhesive tape mould of the bending of supporting plate lower surface reverse side through hold-down screw in the rear and front end of supporting plate.
Described liner and two-sided glued membrane are with the installation site of acetone soln pre-determined bit in the supporting plate bottom.
Described liner, two-sided glued membrane, supporting plate are 90 ℃-160 ℃ of temperature, bond together when exerting pressure 0.1MPa-0.7MPa.
Described liner is a kind of soft PTFE ribbon of having filled inorganic filler (graphite and bronze) and organic filler (polyimides).
Described liner and two-sided glued membrane can also be respectively the arbitrary shapes of equal thickness.
Said supporting plate and rear carrier plate are metal sheeting design.
Advantage of the present invention is: liner and two-sided glued membrane are bonded on the supporting plate with the hot-press method of warming and pressurizing, and technology is simple; This device uses composite filled polytetrafluoroethylene to make liner, and existing certain degree of hardness is wear-resisting again; This device solves the creep problem of conventional adhesion process, Heat stability is good satisfies the air environment harsh environmental conditions; Not only the flatness precision was high after liner was bonding, and adhesive strength is high, is difficult for peeling off or coming off; Be convenient to maintenance and replacing.

1-slip lining device comprises fixed block behind fixed block before the sliding mats, the two-sided glued membrane of 2-, 3-supporting plate, 4-, the 5-, 6-hold-down screw, 7-rear carrier plate, 8-cabinet, 9-installation bracket, 10-gum layer, 11-slip lining.
Embodiment:
Below in conjunction with accompanying drawing the present invention is elaborated.
The application site of the present invention in avionic device is as shown in Figure 1, and slip lining 11 upper surfaces for the bottom surface of electronic equipment chassis 8 and installation bracket 9 provide the contact-making surface of low frictional resistance.
As can beappreciated from fig. 2; Slip lining 11 is parts of installation bracket 9 structures; Liner 1 is generally using with two-sided glued membrane 2; The liner that processes 1 and two-sided glued membrane 2 temperature be 103 ℃, the condition of pressure 0.5MPa be bonded in supporting plate 3 bottoms upper surface on, form two smooth sliding contact planes.The part that liner 1 and two-sided glued membrane 2 exceed pallet length bends and is bonded in the lower surface of supporting plate 3 bottoms downwards, and its degree of crook satisfies the requirement of the bending radius of liner 1 and two-sided glued membrane 2, and is as shown in Figure 4, guarantees can not rupture because stress concentrates.The hot pressing bonding method uses mould to accomplish, and all there is gum layer shown in Figure 5 10 on two surfaces of two-sided glued membrane 2, and gum layer 10 can melt under 103 ℃, the condition of 0.5MPa and is glassy colloid, and solidify the cooling back, bonds together liner 1 and supporting plate 3 securely.
As can beappreciated from fig. 3, slip lining 11 has 7 kinds of parts, is respectively liner 1, two-sided glued membrane 2, supporting plate 3, preceding fixed block 4, back fixed block 5, hold-down screw 6, rear carrier plate 7.At the two ends of supporting plate, with hold-down screw 6 bonding liner 1, two-sided glued membrane 2, supporting plate 3 and rear carrier plate 7 are fixed on preceding fixed block 4 and the back fixed block 5 respectively.
When loading and unloading electronic equipment aboard, electronic equipment chassis 8 pushes or pulls out on the upper surface slave unit installation bracket 9 of slip lining 11.
