This invention discloses a welding device based on a robotic arm, relating to the field of welding technology. To address the issue of flexible connection, the device specifically includes a fixed base and a motion table connected to the fixed base via a multi-degree-of-freedom motion arm. A welding torch is connected to the other side of the motion table via a flexible connection mechanism. The flexible connection mechanism includes a mounting base and a housing. The housing is bolted to the outer wall of the motion table, and the inner wall of the housing is fixed with multiple limiting brackets for limiting the position of the mounting base. This invention achieves a flexible connection between the welding torch and the moving end of the multi-degree-of-freedom motion arm by using an elastic body between the moving end of the multi-degree-of-freedom motion arm and the welding torch. This elastic body has two deformation thin-walled regions, namely, a first deformation thin-walled region and a second deformation thin-walled region. This achieves a buffering effect, reducing the calibration pressure before welding and preventing the welding torch from getting stuck or detaching from the weld.

The utility model discloses a movable main mould stripping mechanism, including the movable rod of clearance fit assembly in the cold header body, the spring seat ring of one end of movable rod is provided with the restriction compression spring activity, the other end of movable rod is provided with the front fixed plate, and the stripping plate of the main mould mouth is assembled to the front fixed plate, the first step cavity of accommodating spring seat ring movement is provided in the cold header body, the second step cavity of accommodating front fixed plate movement is provided in the cold header body, and the third step cavity of accommodating compression spring movement is provided in the cold header body, and the whole movable main mould stripping mechanism is installed on the clamp moving mechanism of cold header, and power is provided by it. Through increasing movable main mould stripping mechanism on the clamp moving mechanism of cold header, the stripping plate can have back and forth action to the main mould mouth, and for the product that can not fall off naturally because of burr and the like, can push off from the main mould mouth, prevent being stuck.

The present application relates to air conditioning equipment technical field, specifically to a kind of air-cooled self-adapting constant temperature and humidity air conditioning unit, including air duct component, drive component, defrosting component and heat insulation component;Air duct component is arranged two groups respectively in the front and back of evaporator;Drive component is connected with air duct component;Defrosting component is arranged above evaporator;Heat insulation component is connected with drive component;Through ultrasonic defrosting and reverse cycle defrosting combination, and evaporator is closed to form vertical air duct in defrosting process, frost layer and water vapor will be blown into water collecting tank by the wind of small fan and discharged, ensure that subsequent dehumidification time will not be extended and can be greatly shortened defrosting time, to reduce energy consumption, solve the dehumidification before low temperature and high humidity working condition need first defrosting, and defrosting will lead to humidity rebound to make dehumidification time extend, cause energy consumption to increase problem.
