Description
Technical Field
The utility model relates to a mistake proofing structure, in particular to a mistake proofing structure controlled by pure pneumatic.
Background
The welding fixture can well guarantee the size of a welded part, improve assembly precision and welding efficiency, and simultaneously face another common problem, namely error proofing, no matter aerospace, automobiles or furniture appliances, a plurality of similar parts always appear in the welded part, or products needing to distinguish the front side and the back side and distinguish left and right parts.
In actual production process, the more product of size difference, the more special product of shape, can be through the appearance mistake proofing, the mistake proofing hole mistake proofing, this is accomplished more easily, but there are some products, self difference is little, perhaps the trompil can influence the outward appearance, influence service function, product property ability etc. to this type of product, now use photoelectricity mostly, automatically controlled mistake proofing such as proximity switch, this type mistake proofing requires for welding work station higher, need supporting equipment, the cost is higher and also damage more easily.
Therefore, a mistake-proofing structure with good adaptability, wide application range and low cost needs to be researched urgently.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the defects of the technology and provide a mistake-proofing structure controlled by pure pneumatic.
In order to solve the technical problems, the utility model provides a pure pneumatic control mistake proofing structure which comprises a first air cylinder, an air valve, a second air cylinder, a mounting frame and a placing groove, wherein the first air cylinder is arranged at the top of the mounting frame, the output end of the first air cylinder is provided with a pressing arm, the air valve is provided with an air inlet switch, an air outlet hole and an air whistle mounting hole, the air inlet of the first air cylinder is connected with the air outlet hole through a pipeline, the output end of the second air cylinder is provided with a telescopic rod, one end, far away from the second air cylinder, of the telescopic rod is provided with a top plate, and a top plate body is provided with a thimble.
As an improvement, the placing groove is provided with a workpiece, and one end of the side wall of the workpiece body, which is close to the placing groove, is provided with a through hole.
As an improvement, an adjusting valve is arranged in an air whistle mounting hole of the air valve, and an air whistle is arranged at the outlet of the adjusting valve.
Compared with the prior art, the utility model has the advantages that: the device can effectively save the manufacturing cost of the welding tool, effectively avoid batch production accidents caused by mistaken clamping of workers and improve the production efficiency.

Detailed Description
The error-proofing structure of the present invention controlled by pure pneumatic will be further described in detail with reference to the accompanying drawings.
With reference to fig. 1-4, a by pure pneumatic control's mistake proofing structure, includes cylinder 2, pneumatic valve 3, No. two cylinders 6, mounting bracket 10 and standing groove 11, cylinder 2 sets up in mounting bracket 10 top, the output of cylinder 2 is equipped with compresses tightly arm 14, pneumatic valve 3 is equipped with air inlet switch 16, venthole 15 and gas whistle mounting hole 13, 2 air inlets of cylinder pass through the pipe connection with venthole 15, the output of No. two cylinders 6 is equipped with telescopic link 8, the one end that No. two cylinders 6 were kept away from to telescopic link 8 is equipped with roof 9, roof 9 plate body is equipped with thimble 7.
As the preferred embodiment of the embodiment, the placing groove 11 is provided with the workpiece 1, and one end of the side wall of the body of the workpiece 1, which is close to the placing groove 11, is provided with a through hole 12.
As the preferred embodiment of the embodiment, the air whistle mounting hole 13 of the air valve 3 is provided with the regulating valve 4, and the outlet of the regulating valve 4 is provided with the air whistle 5.
When the device is used, after a workpiece 1 is clamped and placed in the placing groove 11, the second cylinder 6 pushes the top plate 9 to move through the telescopic rod 8, when the workpiece 1 is clamped and placed correctly, the ejector pin 7 enters the through hole 12, the top plate 9 pushes the air inlet switch 16 to act to open the air valve 3, driving air enters the first cylinder 2 through the pipeline from the air outlet 15 of the air valve 3, and the first cylinder 2 drives the pressing arm 14 to press the workpiece 1, so that the welding work can be continued; when work piece 1 presss from both sides the dress and places the mistake, thimble 7 can't get into through-hole 12 to make the unable antedisplacement of roof 9 open air inlet switch 16, drive gas will be discharged by the gas whistle mounting hole 13 of pneumatic valve 3 this moment, the gas whistle mounting hole 13 of pneumatic valve 3 is equipped with governing valve 4, governing valve 4 exit is equipped with gas whistle 5, and drive gas will blow gas whistle 5, reminds operating personnel, governing valve 4 can be used to adjust drive gas flow, thereby control gas whistle 5's sound size.
