Description
Technical field
What the present invention relates to is a kind of vacuum chamber hermatic door, the sealing door device that especially a kind of heavy slab electron beam welding vacuum chamber is used.
Background technology
In vacuum welding, with in production technology, door for vacuum chamber is extremely important owing to relating to vacuum seal effect, requires to possess good sealing performance and high voltage performance.Because workpiece in large-scale production process needs frequent turnover vacuum chamber, need frequent switch door for vacuum chamber, door for vacuum chamber is necessary stressed evenly, simple to operation, stable, is convenient to safeguard.In the prior art, the technical scheme approaching the most with the application is the door for vacuum chamber in use, mostly this door for vacuum chamber is the door for vacuum chamber that volume is less, for sheet slab vacuum welding vacuum chamber, because the volume of the larger vacuum chamber of workpiece is also large, due to traditional single-shaft-rotation formula door for vacuum chamber structure, when operation, need manually to compress and lock, slow and time-consuming, cause prouctiveness low, be not suitable with sheet slab vacuum welding vacuum chamber and use.And this type of door is due to short near rotating shaft one side rotational travel, easily causes a both sides sealing pressure inhomogeneous, makes equipment be prone to deformed damaged, this is the existing weak point of prior art.
Summary of the invention
Technical problem to be solved by this invention, be exactly for the existing deficiency of prior art, and the sealing door device technical scheme that provides a kind of heavy slab electron beam welding vacuum chamber to use, this scheme adopts horizontal guide rail above doorframe, on guide rail, have and can control two coasters that move along guide rail, two coasters pass through rod hinge connection with the left and right sides of door body, two guide wheels up and down that are fixed with outstanding door dignity at the upper and lower two ends, right side of door body slide on doorframe boss, corresponding with door body upper block, between the right side at the upper and lower two ends of doorframe boss and doorframe, there is guide wheel guide rail.This structure can make translation between Men Tiyu doorframe, and opens or close a body by the guide wheel guide rail on guide wheel and doorframe on door body.Therefore this programme can be applicable to door for large-scale vacuum chamber, and can ensure all even sealings of pressure at both sides of door, and door body is not yielding.
This programme is achieved by the following technical measures: the sealing door device that heavy slab electron beam welding vacuum chamber is used, include doorframe and door body, and the feature of this programme is to have doorframe boss at the internal orifice periphery of described doorframe, on this doorframe boss, has weather strip; Above described doorframe, there is horizontal guide rail, on this guide rail, have move along guide rail from fly block and drive coaster, the described left rod hinge connection that passes on left from fly block and described door body, the right side of described driving coaster and described door body is hinged by right connecting rod; In the door dignity at the up and down two ends adjacent with doorframe, the right side of described door body, two guide wheels up and down that are fixed with outstanding door dignity slide on doorframe boss; Between the right side at the described upper and lower two ends of doorframe boss and doorframe, there is guide wheel guide rail.The concrete feature of this programme also has, and described driving coaster is to drive reducer by motor, and output gear of speed reducer drives sheave to form.Its cross section of described guide rail is I shape.The surface roughness of described Men Tiyu doorframe adjacent surface is less than 3.2um.Between the axle wired-AND gate body plane of described left connecting rod and right connecting rod, there is the projection angle of a 10-18 degree.Described door frame boss exceeds doorframe 35-45 millimeter.
The beneficial effect of this programme can learn according to the narration to such scheme, in this scheme, have doorframe boss at the internal orifice periphery of doorframe, on this doorframe boss, has weather strip.Above described doorframe, there is horizontal guide rail, on this guide rail, have move along guide rail from fly block and drive coaster, the described left rod hinge connection that passes on left from fly block and described door body, the right side of described driving coaster and described door body is hinged by right connecting rod.In the door dignity at the up and down two ends adjacent with doorframe, the right side of described door body, be fixed with outstanding honorable two guide wheels up and down and slide on doorframe boss, between the right side at the described upper and lower two ends of doorframe boss and doorframe, there is the guide wheel guide rail corresponding with guide wheel.This structure, door body is hinged by left and right connecting rod and two coasters, and two coasters are to move on the guide rail above doorframe, therefore Men Tike and doorframe relative translation.Two guide wheels up and down that are fixed with outstanding door dignity due to upper and lower two ends, the right side at door body slide on doorframe boss, corresponding with door body upper block, between the right side at the upper and lower two ends of doorframe boss and doorframe, have guide wheel guide rail.The existence of guide wheel can make a body on doorframe when translation, and Men Tiyu doorframe does not contact.In the time closing body, guide wheel departs from doorframe boss and glides along guide wheel guide rail, makes Men Tixiang doorframe draw close and contact sealing.In the time of door capable of being opened body, guide wheel, along moving on to doorframe boss on guide wheel guide rail, separates Men Tiyu doorframe and opens the door.Therefore this programme can be applicable to door for large-scale vacuum chamber, is conducive to frequent opening and closing, easy to operate, and can ensure all even sealings of pressure at both sides of door, and door body is not yielding.As can be seen here, the present invention compared with prior art, has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.
