A kind of airtight detection mold lifting mechanism
Technical field
The utility model relates to a kind of airtight detection mold lifting mechanism for air tightness detection apparatus.
Background technology
Tubular workpiece needs to carry out air-leakage test to it in process of production, come into the market to prevent substandard products, the Detection results of general air tightness detection apparatus is bad, testing requirement can not be reached, and be not suitable with the detection speed of enterprise's large-scale production, therefore need to design a kind of complete function, Detection results is good, and the air tightness detection apparatus of enterprise's large-scale production needs can be adapted to, and design a kind of mold lifting mechanism for this air tightness detection apparatus.
Utility model content
For the technical problem of above-mentioned existence, the purpose of this utility model is: propose a kind of airtight detection mold lifting mechanism for air tightness detection apparatus.
Technical solution of the present utility model is achieved in that a kind of airtight detection mold lifting mechanism, comprises fixed head, fixed head is provided with holder and fixed mount; Described holder is provided with bed die, fixed mount is provided with slidably main lifting platform and secondary lifting platform; Described fixed mount is provided with main lift cylinders, main lifting platform is provided with secondary lift cylinders; Described main lift cylinders controls main lifting of lifting table, and secondary lift cylinders controls secondary lifting of lifting table; The downside of described secondary lifting platform is provided with mold, and the shape of mold matches with bed die.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Airtight detection mold lifting mechanism of the present utility model, during work, main lifting platform is controlled to decline fast by main lift cylinders, bed die stops close to lift cylinders main after mold, control secondary lifting platform descending at slow speed by secondary lift cylinders, bed die is coordinated with mold workpiece is fixed, the mode be elevated by two-stage cylinder, both ensure that cylinder operation speed, in turn ensure that the stability that mould coordinates.
