Abstract
The invention provides a protective door device. The protective door device comprises a protective door, a balancing weight for balancing the protective door, a lever for connecting the protective door with the balancing weight, a fulcrum on the lever, a support member arranged on the fulcrum, and a buffer damping device fixed on the support member. The buffer damping device comprises a support seat fixed on the support member, a stud arranged on the upper end of the support seat, a spring rod sleeved in the stud, a rotating shaft arranged on the lower end of the support seat, a rotating arm which is axially connected with the rotating shaft, a roller which is axially connected with the rotating arm, and an extension spring connected between the spring rod and the rotating arm, wherein, the roller is positioned below the lever. The protective door device has the beneficial effects that the effect that the balancing weight is not contacted with an operating board is achieved by adjusting the tensile force size and residual deformation range of the extension spring so that the operating table top and even the whole laser equipment are free from the action of residual impact moment, thus ensuring stability of workpieces during the machining process.
Description
[technical field]
The protection field that the present invention relates to a kind of Laser Processing refers more particularly to a kind of protective door device.
[background technology]
Owing to consider that when laser aid is operated laser can cause laser hazard to operating personnel and environment on every side, therefore a protective door device be set on the laser work platform.
Fig. 1 is the structural representation of existing protective door device, and existing protective door device is to utilize lever balance theory, with the protective door 100 and balancing weight 400 counterweighs of the fulcrum on the lever 200 about 210, can reach the labour-saving purpose.Owing to introduced operator's thrust F after the balance, in the protective door use, often limit the maximum open angle of protective door 100, spacing with beam 500 (soft rubber class) usually, because beam 500 elasticity are limited, strain is little, when the balancing weight 400 of big quality strikes beam 500, the strain of beam 500 almost moment reach the limit of resiliency in position, afterwards unnecessary vibrations are transmitted on the complete machine, and then cause the workpiece vibrations, and noise appears.Because in the laser marking process, trickle vibrations may influence the mark effect, so we must eliminate this vibrations.

[specific embodiment]
The present invention is further described below in conjunction with description of drawings and the specific embodiment.
With reference to figure 2-Fig. 5, described protective door device comprises: the protective door 100 that is used to isolate, the balancing weight 400 that is used for balance protective door 100, connect the lever 200 of protective door 100 and balancing weight 400, at the fulcrum on the lever 200 210, be installed on support member 300 on the fulcrum 210, to be positioned at lever 200 other and be fixed on the damping device 600 that is used for whole protective door device buffering on the support member 300.
Whole protective door device is fixed on the operating table surface 700.
With reference to figure 6-Fig. 9, damping device 600, comprise supporting seat 610, supporting seat 610 is provided with convex platform 611 and lower convex platform 612, damping device 600 also comprises: be installed in the double-screw bolt 630 on the convex platform 611, be set in the spring pull bar 620 in the double-screw bolt 630, be installed in the rotating shaft 660 on the lower convex platform 612, with the rotating shaft 660 axial turning arms 670 that are connected, turning arm 670 movable ends inboard and be positioned at lever 200 belows one roller 680 is installed, be connected the extension spring 650 between spring pull bar 620 and the turning arm 670, and between roller 680 and the turning arm 670 is that axis is connected, and roller 680 can turning arm 670 be to roll in the center.
In the present embodiment, an also sheathed locking nut 640 between the upper surface of convex platform 611 and the double-screw bolt 630, be used for the spacing fixing of protective door device double-screw bolt 630, balancing weight 400 is not contacted with operating table surface 700, avoided influencing the stability of workpiece processing because of balancing weight 400 bump operating table surface 700.Because balancing weight 400 does not contact with operating table surface 700, in the present embodiment, balancing weight does not need for 400 times as old structure beam 500 to be set, and sees Fig. 1.
Particularly, on turning arm 670, be provided with a hasp 671, be used for fixing extension spring 650 lower ends.
Particularly, roller 680 adopts polyurethane material (being called for short PU) in the present embodiment, and lever 200 is positioned on the roller 680, and roller 680 can further absorb the portion of energy of lever 200 pair rollers 680, eliminates the noise that produces because of bump simultaneously.
Particularly, be provided with a spacing border 613 corresponding to lower convex platform 612, restriction turning arm 670 slewing areas at turning arm 670.When the roller on the turning arm 670 680 is in when not being subjected to lever 200 pressure status, be the initial position of turning arm 670.
The operation principle of this protective door device is as follows:
In the assembling process of whole protection door gear, referring to Fig. 6-Fig. 8, make turning arm 670 be in initial position, be that roller 680 is not subjected to lever 200 pressure, this moment, protective door was in closed condition, by turn double-screw bolt 630, drove pulling force size and residual deformation scope that spring pull bar 620 is regulated extension spring 650, satisfy the state parameter that uses until reaching one, guarantee the requirement that balancing weight 400 can not contact with operating table surface 700 in the use.By screwing locking nut 640 that double-screw bolt 630 is spacing fixing subsequently.In the process of using, will need not locking nut 640 is regulated.
In use, when operating personnel open when opening protective door 100 by handle 110, lever 200 and roller 680 bumps, roller 680 are subjected to the downward pressure of lever 200.Clashing into moment, extension spring 650 sponges bump moment fully with enough big strain.Simultaneously,, can absorb lever 200 pair rollers 680 portion of energy, play cushioning effect, absorb the noise that is caused because of bump because roller 680 is polyurethane material (being called for short PU).When protective door 100 is in open mode, balancing weight 400 can not contact with operating table surface 700, acts on problem on the complete machine thereby solved surplus bump moment that old structure exists.
The present invention is installed a damping device 600 additional at existing protective door device, by regulating the pulling force size and the residual deformation scope of extension spring 650, reach the effect that balancing weight 400 can not contact with operating table surface 700 in the use, make operating table surface 700 and even whole laser equipment (figure does not show) exempt from the effect of surplus bump moment, guaranteed the stability in the workpiece process.
Although with reference to the accompanying drawings; a kind of protective door device of the present invention is illustrated; but above-mentioned disclosed content only is in order to understand the present invention better; rather than limit the scope of claim by any way; so all according to the described structure of patent claim of the present invention, feature and principle do etc. change or modify, be included in protection scope of the present invention.
