Abstract
The utility model discloses the cold shield plates of architecture advances on a kind of cryopump, it comprises the back-up ring of criss-cross fixed support and taper, the slot of shaping some inclinations on fixed support, back-up ring is plugged in support bracket fastened slot, on the lower side of back-up ring, elongation moulding has vertical ring body, shaping on ring body respectively have several breach, and the side of ring body breach forms flanging, and flanging to be leaned against on the support bracket fastened sidewall of back-up ring and is fixed on fixed support by rivet.Back-up ring in the utility model stationary shadow mask adopts riveted structure to replace welding manner, thus the assembling facilitating baffle is fixed, and decreases the time of assembling, improves manufacturing efficiency.
Description
Technical field:
The utility model relates to the technical field of vacuum low-temperature pump, more specifically to the cold shield plates of architecture advances on a kind of cryopump.
Background technique:
Cryopump is the vacuum pump utilizing low-temperature surface condensed gas, also known as condensate extractionpump.Cryopump is the vacuum pump that ultimate pressure is minimum, the speed of exhaust is maximum obtaining clean vacuum.Be provided with cold screen in cryopump, cold screen internal fixtion has absorbing array and baffle, and baffle is adsorbed with the high gas molecule of attached solidifying point, the low gas molecule of attached solidifying point through baffle by absorbing array is adsorbed.Existing baffle structure as shown in Figure 1, it is made up of the fixed support 1 of font and the back-up ring 2 of taper, back-up ring 2 is plugged on fixed support 1, general need to carry out soldering at each grafting point for anti-Sealing shield ring 2 comes off from fixed support 1 and fix, thus the task amount of soldering is comparatively large, baffle assembling is consuming time longer.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides the cold shield plates of architecture advances on a kind of cryopump, and it facilitates the assembly working of baffle to improve working efficiency.
Technology solution of the present utility model is as follows:
The cold shield plates of architecture advances on a kind of cryopump, comprise the back-up ring of criss-cross fixed support and taper, the slot of shaping some inclinations on fixed support, back-up ring is plugged in support bracket fastened slot, on the lower side of back-up ring, elongation moulding has vertical ring body, ring body forms several breach, the side of ring body breach forms flanging, flanging to be leaned against on the support bracket fastened sidewall of back-up ring and is fixed on fixed support by rivet.
The width of the breach on described ring body is greater than the thickness of every bar bracket lip on fixed support, and breach 211 sleeve is on fixed support.
The fixed support sidewall that the flanging of described ring body leans on mutually with flanging forms corresponding rivet hole.
Described fixed support and back-up ring all adopt red copper, and back-up ring is provided with multiple, and back-up ring is evenly distributed on fixed support to fixed support outer end by by fixed support center.
Described support bracket fastened four ends all form the flange of bending, and flange forms bolt through-hole.
The beneficial effects of the utility model are: the back-up ring in (1), its stationary shadow mask adopts riveted structure to replace welding manner, thus the assembling facilitating baffle is fixed, and decreases the time of assembling, improves manufacturing efficiency.(2), the welding quality of the existing baffle be welded and fixed by the restriction of the welding technique of assembler, baffle firmly and type quality vary with each individual, and it is little to adopt riveted structure to affect by human factor, baffle fixation, profile neat appearance.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of existing cold shield plates;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation that the utility model lacks part back-up ring;
Fig. 4 is the structural representation of the utility model back-up ring.
In figure: 1, fixed support; 2, back-up ring; 11, slot; 12, flange; 21, ring body; 211, breach; 212, flanging; A, rivet hole.
Embodiment:
Embodiment: see shown in Fig. 2 to 4, the cold shield plates of architecture advances on a kind of cryopump, comprise the back-up ring 2 of criss-cross fixed support 1 and taper, the slot 11 of shaping some inclinations on fixed support 1, back-up ring 2 is plugged in the slot 11 of fixed support 1, on the lower side of back-up ring 2, elongation moulding has vertical ring body 21, ring body 21 forms several breach 211, the side of ring body 21 breach 211 forms flanging 212, the sidewall that flanging 212 leans against back-up ring 2 fixed support 1 is fixed on fixed support 1 by rivet.
The width of the breach 211 on described ring body 21 is greater than the thickness of every bar bracket lip on fixed support 1, and breach 211 sleeve is on fixed support 1.
Corresponding rivet hole a is formed on the flanging 212 of described ring body 21 with on fixed support 1 sidewall that flanging 212 leans on mutually.
Described fixed support 1 and back-up ring 2 all adopt red copper, and back-up ring 2 is provided with multiple, and back-up ring 2 is evenly distributed on fixed support 1 to fixed support 1 outer end by by fixed support 1 center.
Four ends of described fixed support 1 all form the flange 12 of bending, and flange 12 forms bolt through-hole.
Working principle: the utility model adopts in baffle design riveted structure, thus adopt riveted joint to replace welding, both the assembly working of baffle had been facilitated, additionally reduce the time of assembling, improve manufacturing efficiency, simultaneously by the considerable influence (welding manner quality is larger by the impact of personnel's welding technique) reducing human factor, thus ensure that the aesthetics of baffle fastness and profile.
