Abstract
The utility model belongs to the technical field of welding processing devices and provides a protective door lifting mechanism for welding. The protective door lifting mechanism for welding comprises a bearing seat, a rotary drum, a protective roller shutter, a chain wheel and chain mechanism, a gear and rack mechanism and an air cylinder, wherein the rotary drum is arranged on the bearing seat, the protective roller shutter is sleeved on the rotary drum, one end of the chain wheel and chain mechanism is connected with the rotary drum, the other end of the chain wheel and chain mechanism is connected with the gear and rack mechanism, and the gear and rack mechanism is connected with the air cylinder. The protective door lifting mechanism for welding has the advantages that the stroke is increased through a gear, a rack and larger and small chain wheels, the stroke of the protective roller shutter is finally increased to 1690mm, and the purpose of integrally protecting operators is achieved. A protecting valve is added at an exhaust port of the air cylinder, so that under the condition that no air exists, the exhaust port is closed, the air cylinder cannot perform action, the protective roller shutter does not descend, and the operators are protected.
Description
Technical field
The utility model relates to the welding processing equipment technical field, particularly relates to a kind of welding protective door elevating mechanism.
Background technology
When auto parts welding, generally all need to use protective door that the scene is protected; existing mechanism is because the stroke of cylinder is limited; if the oversize meeting of stroke here has influence on guidance quality; so the stroke of whole lifting generally has only about 300-400mm; it can only be that protection is arrived operating personnel's chest with top that butt welding fetches; can't accomplish effective protection veritably; in addition because protective door is directly installed on the top; when dying since the deadweight effect; the protection roller shutter can fall automatically, causes security incident easily.
The utility model content
Technical problem to be solved in the utility model is the present situation at prior art, and a kind of welding protective door elevating mechanism is provided, and increases stroke by the protective door elevating mechanism, reaches the purpose to operating personnel's integral protection simultaneously.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of welding protective door elevating mechanism, it is characterized in that, comprise bearing support, cylinder, protection roller shutter, sprocket wheel link chain mechanism, pinion and rack and cylinder, described cylinder is arranged on the bearing support, the protection roller shutter is set on the cylinder, one end of sprocket wheel link chain mechanism is connected with cylinder, and the other end is connected with pinion and rack, and pinion and rack is connected with cylinder.
The measure of taking for the optimization such scheme specifically comprises:
Use in the protective door elevating mechanism in above-mentioned a kind of welding, described sprocket wheel link chain mechanism comprises hinge wheel, minor sprocket and chain, described chain connects minor sprocket and hinge wheel simultaneously, minor sprocket is fixedlyed connected with cylinder, and described pinion and rack comprises gear, tooth bar and rotate coaxially that rack and pinion is connected with a joggle, gear be installed in rotate coaxial on, hinge wheel also be installed in rotate coaxial on, described cylinder is provided with cylinder rod, cylinder rod is fixedlyed connected with the tooth bar lower end.
Use in the protective door elevating mechanism in above-mentioned a kind of welding, have exhaust opening on the described cylinder, exhaust opening is provided with protective valve.Do not having under the situation of gas like this, exhaust opening is closed, and cylinder is with regard to akinesia, and the protection roller shutter just can not descend yet, and has protected operating personnel.
Compared with prior art; advantage of the present utility model is to increase stroke by the form of rack-and-pinion, big minor sprocket; finally make the stroke of protection roller shutter increase to 1690mm; reached the purpose to operating personnel's integral protection, increased protective valve at cylinder exhaust port, do not had under the situation of gas; exhaust opening is closed; cylinder is with regard to akinesia, and the protection roller shutter just can not descend yet, and has protected operating personnel.
