Description
Technical field
What the present invention relates to is that a kind of vacuum chamber is used hermatic door, the hermatic door device that especially a kind of heavy slab electron beam welding vacuum chamber is used.
Background technology
Vacuum welding with production technology in, door for vacuum chamber requires to possess excellent sealing performance and high voltage performance owing to relate to the vacuum seal effect and very important.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, with the most approaching technical scheme of the application be door for vacuum chamber in usefulness, mostly this door for vacuum chamber is that the less vacuum chamber of volume is with door; Vacuum chamber is used in vacuum welding for sheet slab, because the volume of the big vacuum chamber of workpiece is also big, because traditional single shaft rotary type vacuum chamber door; Need manual work to compress and lock during operation; Slow and time-consuming, cause prouctiveness low, the vacuum welding of incompatibility sheet slab is used with vacuum chamber.And this type of door is prone to cause a both sides sealing pressure inhomogeneous because short near rotating shaft one side rotational travel, and the equipment that makes is prone to deformed damaged, and this is the existing in prior technology weak point.
Summary of the invention
Technical problem to be solved by this invention; Be exactly not enough to existing in prior technology; And the hermatic door device technique scheme that provides a kind of heavy slab electron beam welding vacuum chamber to use, this scheme is employed in the doorframe top has horizontal guide rail, on guide rail, has 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 two guide wheels up and down of being fixed with outstanding door dignity slide on the doorframe boss up and down on the right side of door body, and are corresponding with door body upper block, between right side and the doorframe at two ends the guide wheel guide rail arranged up and down at the doorframe boss.This structure can make translation between the Men Tiyu doorframe, and opens or close a body by guide wheel on the door body and the guide wheel guide rail on the doorframe.So this programme can be fit to the large-scale vacuum chamber with door, and can guarantee all even sealing of pressure at both sides of door, and the door body is not yielding.
This programme is realized through following technical measures: the hermatic door device that heavy slab electron beam welding vacuum chamber is used, include a doorframe and a door body, and the characteristics of this programme are that the internal orifice periphery at said doorframe has the doorframe boss, on this doorframe boss, weather strip are arranged; Horizontal guide rail is arranged above described doorframe; On this guide rail, have along guide rail move from fly block with drive coaster; The described left rod hinge connection that passes on left from fly block and said door body, the right side of described driving coaster and said door body is hinged through right connecting rod; On the door dignity at the up and down two ends adjacent with doorframe, the right side of said door body, two guide wheels up and down that are fixed with outstanding door dignity slide on 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 constitutes.Its cross section of described guide rail is an 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 every 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 on this doorframe boss, weather strip arranged.Horizontal guide rail is arranged above described doorframe; On this guide rail, have along guide rail move from fly block with drive coaster; The described left rod hinge connection that passes on left from fly block and said door body, the right side of described driving coaster and said door body is hinged through right connecting rod.On the door dignity at the up and down two ends adjacent, the right side of said door body with doorframe, be fixed with honorable two guide wheels up and down of outstanding door and on the doorframe boss, slide, 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 through left and right connecting rod and two coasters, and two coasters are on the guide rail above the doorframe, to move, so Men Tike and doorframe relative translation.Two guide wheels up and down that are fixed with outstanding door dignity owing to two ends about the right side of door body slide on the doorframe boss, and are corresponding with door body upper block, about the doorframe boss, between the right side at two ends and the doorframe guide wheel guide rail arranged.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, and the Men Tixiang doorframe is drawn close and contact seal.When opening the door 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, helps frequent opening and closing, and is easy to operate, and can guarantee all even sealing of pressure at both sides of door, and the door body is not yielding.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
