Description of drawings:
Fig. 1 is a structure chart of the present invention.
Embodiment:
The present invention is made up of stay-warm case mechanism and energising contact mechanism.Stay-warm case mechanism mainly is made of parts such as ceramic block 13, heat-preservation cotton 9, inner cap 11, enclosing cover 10, ceramic block 12, adjustment screw 14, supporting bracket 6, urceolus 8, inner cores 4, its structural principle is: stay-warm case is clipped in heat-preservation cotton 9 between the two with inner/outer tube 4,8, upper and lower side blocks with inner cap 11, enclosing cover 10, ceramic block 13, ceramic block 12 respectively, forms an insulation entity.Inner cap is connected by ceramic block 12 with enclosing cover, and regulates the gap of inner cap and enclosing cover by ceramic block 12, and they are not contacted, and heat can not be conducted to the external world; The ceramic block 13 of bottom also has the outwards effect of conduction of heat that prevents in the cup type stay-warm case in addition, and next heat-preservation cotton that is clipped between inner/outer tube can prevent that heat directly is radiated the external world from interior bucket.Because this cup type stay-warm case has adopted above structure, therefore, when it covers the magnetron heating, can play good heat insulation effect.
The energising contact mechanism mainly is made up of spring 18 (2), support plate 17, support plate 7, ceramic wafer 16, binding post 2 (2), ceramic wafer 15 (2).Its structural principle is: two ceramic wafers 15 are enclosed within respectively on two binding posts 2, pass ceramic wafer 16 then.On two pipe binding posts, put two springs 18 respectively again, pass support plate 17 again, respectively two binding posts are fixed on support plate 17 and the ceramic wafer 16 with nut 19 simultaneously; In addition, also support plate 17 and ceramic wafer 16 are separately fixed on the support plate on 7, make two binding posts can only rely on the effect of spring and move up and down with bolt.When magnetron heated, even produce a lot of heats, but because ceramic wafer 16 can prevent heat radiation to spring, not outer ceramic wafer 16 can prevent that the heat that support plate 7 absorbs from passing to spring again, thereby makes the ILS of spring.In addition; two ceramic wafers 15 that are enclosed within two binding post lower ends can rely on it self weight; and because ceramic wafer 15 adopts taper surface with binding post mating surface place; therefore it can freely fall to binding post bottom; therefore; even under special circumstances; cause two binding posts to swing; two terminals are directly contacted; can only be that two ceramic wafers 15 come in contact; and ceramic wafer 15 is insulators, so can not cause the risk of short-circuits situation, has so just increased the safeguard protection coefficient to magnetron.
The whole operation of existing common apparatus is to finish installation, dismounting and the contact pressing of warming plate by manual operation, complex operation but also in dismounting during warming plate not only, operating personnel will cause operating condition abominable with the warming plate that hand goes to contact roasting heat, and its locating effect is bad.And the pneumatic principle that the present invention adopts is realized automatic control by cylinder, makes stay-warm case to descend automatically and to rise, and moves steadily, and stay-warm case adopts floating type design simultaneously.Have guide function concurrently, two binding posts by electric contact mechanism adopt the free design that independently moves up and down in addition.Guaranteed can not cause damage when this automatic positioning mechanism descends, so not only improved production efficiency, improved operating condition simultaneously magnetron.Its structural principle is: when this automatic positioning mechanism moves down in the process that covers magnetron, when the diameter largest portion of magnetron begins to enter stay-warm case, because ceramic block 13 adopts horn designs, has good guide effect, make magnetron enter inner core very smoothly, bigger because of the inner core internal diameter again than magnetron external diameter, stay-warm case is moved down, when the upper end of magnetron and inner cap near the time, because the horn mouth design is adopted in inner cap and supporting bracket bottom, and the aperture in the hole that the inner cap ceramic block is opened is bigger than the external diameter of magnetron upper end, therefore, by three guiding, stay-warm case can be covered very easily, and the upper surface and the inner cap lower surface of the largest segment of magnetron tightly are close to, thereby make the magnetron upper end pass cup type stay-warm case, for contacting with the energising contact mechanism, two contacts of magnetron prepare, in the process that two contacts of magnetron contact, because the lower surface contact area of binding post is bigger with respect to the contact area of the contact point of magnetron, even magnetron skew certain angle is (in the production, the workman will with the naked eye adjust the position of magnetron, make it be in best station), binding post is contacted with the magnetron contact, in addition, owing to be with spring on two binding posts, even just differ in two contacts, two binding posts also can independently move up and down, and two binding posts can closely be contacted with two contacts of magnetron, thereby make magnetron in mechanism, locate automatically, and be in the optimum position.
