Description

Technical Field

[0001] The utility model belongs to the technical field of welding protection, in particular to a workpiece welding processing protection mechanism. Background Art

[0002] Workpiece refers to the object to be processed during machining. It can be a single part or a combination of several parts fixed together. There are various types of workpiece processing methods, including turning, milling, planing, grinding, casting, forging, etc. The processing procedures of workpieces also change with the changes in processing methods. Welding is a common way to connect two parts together. It uses high temperature to melt metal or welds two workpieces with melted solder. Therefore, this is a way to connect metal workpieces. During welding, protective devices are generally used to protect operators and metal workpieces. The protective device isolates the metal workpiece from the operator to ensure the welding quality of the metal workpiece. Generally, the protective cover is a protective mask, which needs to be held by the welder for protection. Such a protective mask can only protect the face and eyes, and is extremely inconvenient to operate. One hand holds it and the other hand welds. There are safety hazards, which affect the safety of the welder. However, such a workpiece welding protective structure has poor protection effect and safety hazards, which affect the safety of the welder. Utility Model Content

A clamping groove 7 is opened on one side of the placement groove 6, and a fixing plate 8 is connected to both sides of the upper end of the base 1, and a clamping block 9 is connected to one end of the fixing plate 8, and one end of the clamping block 9 extends to the inside of the clamping groove 7. One end of the clamping block 9 is arranged in an inclined structure, and one end of the clamping block 9 extends through and extends to the inside of the fixing plate 8 and is connected to a pressing plate 10, and one end of the pressing plate 10 is connected to a spring 11, and the springs 11 have telescopic properties, so that the clamping block 9 can be telescopic according to usage requirements, and one end of the spring 11 is connected to one side of the inner part of the fixing plate 8.

[0021] Reference Figure 4 The adsorption component 5 includes a suction fan 51 installed on one side of the upper end of the protective cover 2, and the waste generated by the welding of the protective cover 2 is absorbed by the suction fan 51. One end of the suction fan 51 is connected to an absorption pipe 52, and one end of the absorption pipe 52 extends through the inside of the protective cover 2. The output end of the suction fan 51 is connected to a filter box 53, and one end of the filter box 53 is connected to a dust filter 54. The dust filter 54 blocks dust in the air to prevent dust from entering the inside of the protective cover 2. One side of the inside of the filter box 53 is connected in sequence to an activated carbon filter plate 55, an organic resin adsorption plate 56 and an activated fiber plate 57. When the exhaust gas enters the inside of the filter box 53, under the multiple adsorption and filtration of the activated carbon filter plate 55, the organic resin adsorption plate 56 and the activated fiber plate 57, the harmful substances in the welding fume are effectively processed, thereby avoiding the operator from inhaling welding fume and causing injuries such as coughing and asthma, protecting the operator's safety during welding work, and preventing the exhaust gas from polluting the environment.

Under the action of external force, the clamping block 9 drives the pressure plate 10 to squeeze the spring 11, so that the clamping block 9 is retracted to the inside of the fixed plate 8. At this time, the fixed plate 8 is inserted into the placement groove 6. When the clamping block and the clamping groove 7 are in the same horizontal plane, the clamping block is inserted into the clamping groove 7 under the elastic potential energy of the spring 11, so that the protective cover 2 and the base 1 are fixedly connected, which plays a protective role for the welder. The exhaust gas generated by welding is absorbed into the inside of the filter box 53 by the suction fan 51. Under the multiple adsorption and filtration of the activated carbon filter plate 55, the organic resin adsorption plate 56 and the activated fiber plate 57, the harmful substances in the welding fume are effectively processed, so as to avoid the operator from inhaling welding fume and causing coughing and asthma, thereby protecting the operator's safety during welding work and avoiding the pollution of the environment by the exhaust gas.
