Description
Technical field
The utility model relates to 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
With in the production technology, door for vacuum chamber is very important owing to relate to the vacuum seal effect in vacuum welding, requires to possess good sealing performance and high voltage performance.Because workpiece need frequently pass in and out vacuum chamber in the large-scale production process, needs frequent switch door for vacuum chamber, door for vacuum chamber must be stressed even, simple to operation, stable, is convenient to safeguard.In the prior art, the technical scheme that approaches the most with the application is the door for vacuum chamber in usefulness, 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, because traditional single-shaft-rotation formula door for vacuum chamber structure, need artificial the compression and locking during operation, slow and time-consuming, cause prouctiveness low, be not suitable with the sheet slab vacuum welding and use with vacuum chamber.And this type of door easily causes a both sides sealing pressure inhomogeneous because short near rotating shaft one side rotational travel, so that equipment is prone to deformed damaged, this is the existing weak point of prior art.
Summary of the invention
Technical problem to be solved in the utility model, 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, have at guide rail 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 ends up and down two guide wheels of being fixed with outstanding door dignity slide at the doorframe boss up and down on the right side of door body, corresponding with door body upper block, about the doorframe boss, between the right side at two ends and the doorframe guide wheel guide rail is arranged.This structure can make translation between the Men Tiyu doorframe, and opens or close a body by the guide wheel on the door body and the guide wheel guide rail on the doorframe.So this programme can be fit to large-scale vacuum chamber door, and can guarantee all even sealings of pressure at both sides of door, and the 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 a door body, and the characteristics of this programme are that the internal orifice periphery at described doorframe has the doorframe boss, at this doorframe boss weather strip are arranged; Horizontal guide rail is arranged above described doorframe, this guide rail have along guide rail move 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; On the door dignity at the up and down two ends adjacent with doorframe, the right side of described door body, up and down two guide wheels that are fixed with outstanding door dignity slide at the doorframe boss; About described doorframe boss, between the right side at two ends and the doorframe guide wheel guide rail is arranged.The concrete characteristics of this programme also have, and described driving coaster is by the motor-driven reducer, and output gear of speed reducer drives sheave and consists of.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.The projection angle that a 10-18 degree is arranged between the axle wired-AND gate body plane of described left connecting rod and right connecting rod.Described door frame boss exceeds doorframe 35-45 millimeter.
The beneficial effect of this programme can learn according to the narration to such scheme, because in this scheme, at the internal orifice periphery of doorframe the doorframe boss arranged, and at this doorframe boss weather strip arranged.Horizontal guide rail is arranged above described doorframe, this guide rail have along guide rail move 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.On the door dignity at the up and down two ends adjacent with doorframe, the right side of described door body, be fixed with honorable up and down two guide wheels of outstanding door and slide at the doorframe boss, about described doorframe boss, between the right side at two ends and the doorframe guide wheel guide rail corresponding with guide wheel arranged.This structure, the door body is hinged by left and right connecting rod and two coasters, and that two coasters are guide rails above doorframe is mobile, so Men Tike and doorframe relative translation.Up and down two guide wheels that are fixed with outstanding door dignity owing to two ends about the right side of door body slide at the doorframe boss, and are corresponding with door body upper block, between the right side at two ends and the doorframe guide wheel guide rail arranged about the doorframe boss.The existence of guide wheel can make a body on doorframe during translation, and the Men Tiyu doorframe does not contact.When closing body, guide wheel breaks away from the doorframe boss and glides along the guide wheel guide rail, makes the Men Tixiang doorframe draw close and contact sealing.When the door capable of being opened body, guide wheel separates the Men Tiyu doorframe and opens the door along moving on to the doorframe boss on the guide wheel guide rail.So this programme can be fit to the large-scale vacuum chamber with door, is conducive to frequent opening and closing, and is easy to operate, and can guarantee all even sealings of pressure at both sides of door, and the door body is not yielding.This shows that the utility model compared with prior art has outstanding substantive distinguishing features and significant progressive, the beneficial effect of its enforcement also is apparent.
