Abstract
The utility model provides a hold -down mechanism of real empty room box door, the cylinder fixing base is established to its characteristics on real empty room box, establish the cylinder on the cylinder fixing base, establishes the supporting seat between cylinder and box door on the cylinder fixing base, establishes the linking arm on the supporting seat, establishes the lever on cylinderpiston tip and linking arm, and the lever is articulated with the linking arm, and the one end and the cylinderpiston end connection of lever establish the buffering pressure pad on the other end of lever. The utility model discloses a cylinderpiston's removal, the buffering pressure pad of the lever other end can firmly compress tightly the box door reliably and make it to become sealed real empty room hold the chamber on the box, have save trouble, laborsaving, swift advantage, can be general on all kinds of big small -size's box, commonality, strong adaptability.
Description
Technical field
The utility model relates to vacuum chamber cabinet door, is specifically related to a kind of hold-down mechanism of vacuum chamber cabinet door, is a kind of hold-down mechanism of vacuum plating unit cabinet door.
Background technology
Nearly two during the last ten years, and high-end optical vacuum coating equipment is widely applied rapidly in China and popularizes.Vacuum plating unit in use, need the cabinet door shutting vacuum chamber, outer power forces together cabinet door and casing reliably, tightly simultaneously, do not allow the phenomenon having gas leakage between the two, make it cavity volume---the vacuum chamber of formation one sealing, this ensures that the vacuum pump of vacuum plating unit starts one of vacuum chamber work necessary precondition.
How providing the external force that one enough large like a cork, vacuum plating box body and cabinet door are forced together tightly, become the vacuum chamber cavity volume of a sealing and do not have a gap, is the key that hold-down mechanism needs to solve.At present, domestic originally mostly adopt the hold-down mechanism of Purely mechanical with existing vacuum plating unit, this type of hold-down mechanism is from structure point, and mainly contain two types, one is simple mechanical compaction mechanism, and two is more complicated mechanical compaction mechanisms.
For simple mechanical compaction mechanism, its advantage structure is simple, easily manufactured, with low cost, is mainly used in, on original and existing domestic vacuum plating unit, being applicable to the body structure of box body diameter size smaller (generally at below 800mm).Its shortcoming is together with chamber door is pressed onto with casing time, compares effort, when cabinet door have be out of shape in a small amount time, compress and more require great effort, and be only limitted to use compared with the compression of small box size, corresponding compressing component cam, rolling wheel wear are very fast, work-ing life is shorter, needs often regular maintenance and replacing.
For the hold-down mechanism of complexity, its complicated structure, manufacture the process-cycle long, production cost is higher, and accessory size is larger, for vacuum chamber box sizes less with bigger than normal all practical.Its advantage is when using this structure to compress cabinet door and casing, and stability of rotation is flexible, more laborsaving, even if cabinet door has distortion in a small amount, compress also more laborsaving, work-ing life is relatively long.Its shortcoming is that manufacture difficulty strengthens, and the process for processing cycle is elongated, and assembling manufacturing cost increases greatly, economical poor, and this also makes it on domestic vacuum plating unit, can not get widespread use.
Therefore, be necessary to manufacture and design that one saves trouble, laborsaving, vacuum chamber cabinet door hold-down mechanism efficiently.
Summary of the invention
Technical problem to be solved in the utility model designs a kind of hold-down mechanism of vacuum chamber cabinet door, and this hold-down mechanism is saved trouble when compressing vacuum chamber cabinet door, laborsaving, quick.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of hold-down mechanism of vacuum chamber cabinet door, comprise the cabinet door of vacuum chamber casing, cylinder permanent seat established by described vacuum chamber casing, cylinder established by cylinder permanent seat, supporting seat is established between cylinder permanent seat upper cylinder and cabinet door, supporting seat establishes connecting arm, lever is established in cylinder piston end and connecting arm, lever and connecting arm hinged, one end of lever is connected with cylinder piston end, and the other end of lever establishes buffer pressure pad.
The connection gas circuit of described cylinder establishes magnetic valve, and magnetic valve is controlled by push button.
The utility model adopts the hold-down mechanism of a kind of vacuum chamber cabinet door designed by technique scheme, due to cylinder being established by the cylinder permanent seat on vacuum chamber casing, cylinder piston end is connected with lever end, connecting arm is as the fulcrum of lever, by the movement of cylinder piston, the buffer pressure pad of the lever the other end can be pressed on casing solid and reliable for cabinet door, thus makes it the vacuum chamber cavity volume becoming sealing.The utility model is compared vacuum chamber cabinet door compressing method with traditional, have save trouble, laborsaving, advantage efficiently, there are good economic results in society.
Accompanying drawing explanation
Fig. 1 represents the structural representation of the hold-down mechanism of a kind of vacuum chamber cabinet door of the utility model.
Embodiment
Illustrate below in conjunction with the structure of accompanying drawing to the hold-down mechanism of a kind of vacuum chamber cabinet door of the utility model.
See Fig. 1, the hold-down mechanism of a kind of vacuum chamber cabinet door of the utility model, comprise the cabinet door 9 of vacuum chamber casing, vacuum chamber casing is established cylinder permanent seat 2, cylinder permanent seat 2 is established cylinder 1, the connection gas circuit of cylinder 1 establishes magnetic valve, magnetic valve is used for control cylinder clamping stroke, magnetic valve is controlled by push button, so that manipulating cylinder.Pneumatic clamping of the present utility model instead of pure mechanical force and compresses, and this type of optical vacuum filming equipment itself is with compressed air source unit, and this hold-down mechanism source of the gas used, does not need the corresponding compressed air source unit of special increase in addition.Supporting seat 3 is established between cylinder permanent seat 2 upper cylinder 1 and cabinet door 9, supporting seat 3 is established connecting arm 7, lever 4 is established in cylinder piston end and connecting arm 7, and lever 4 is hinged by bearing pin 6 with connecting arm 7, and one end of lever 4 is connected by bearing pin 5 with cylinder piston end.The other end of lever 4 is established buffer pressure pad 8, when compressing cabinet door, buffer pressure pad 8 is conducive to guard box surface, reduces tank surface wearing and tearing, ensures the reliably reliable of compression.
The utility model is when compressing the cabinet door 9 of vacuum chamber casing, and push button is by magnetic valve manipulating cylinder, and cylinder piston activation lever 4 is rotated around connecting arm 7, and under the effect of cylinder piston, buffer pressure pad 8 implements the compression operation to cabinet door.Owing to being pneumatic clamping, compress speed and the equal adjustable size of snap-in force, the utility model snap-in force is large, compresses reliable, time saving and energy saving.
Pneumatic clamping mechanism of the present utility model, can be general on the casing of all kinds of size dimension, only need by increase and decrease conversion pneumatic clamping mechanism quantity.There is low processing cost, versatility, adaptable feature.
