Abstract
The utility model discloses a portable pneumatic saw, which can cut off workpieces quickly by that the air is compressed to push a plunger make alternating motion to do work. The utility model which has the advantages of time saving and labor saving is suitable for the requirements of the maintenance work of industrial and mining establishments.
Description
The utility model relates to a kind of portable pneumatic saw, especially multi-functional pneumatic saw.
When industrial and mining enterprises keeped in repair, running into needed sawed-off steel, when non-ferrous metal, timber, plastics, insulation material, often adopts hand saws, and labour intensity is big.
The utility model provides a kind of Pneumatic saw, in the place that compressed air source is arranged, can finish the work that in the past needs handwork convenient and strength-savingly.
The utility model is achieved in that compressed air passes through switching control pilot by air inlet, and reversal valve enters a side of cylinder, promotes piston and moves.After piston moved a segment distance, lance promoted reversal valve, opens cylinder opposite side air admission hole, and previous air admission hole and steam vent communicate, and piston moves in the opposite direction.Go down and so forth, the piston band connecting rod and is done straight reciprocating motion.Piston nose is equipped with saw blade, so just can reach the purpose of work.File or scraper can also be changed on the piston rod, so just other operations can be finished.
The utility model is simple in structure, and is easy to operate, reduces labor intensity.
In conjunction with the Pneumatic saw front section view, introduce an embodiment.
The bottom of manual saw handle 11 is as compressed-air actuated import, and compressed air passes through switching control pilot 12, approach axis commutation valve body 13, and reversing valve core 14 is in the right of valve body 13, has closed rear exhaust port.At this moment the air admission hole of front end housing 5 communicates with front-seat gas port, and compressed air enters cylinder back cover 10 promotion pistons 9 and moves to left.When piston 9 during near the dead point, piston rod 6 is being with lance 16 also to move to left side bump pull bar 15, reversing valve core 14 is moved to left, the passage of sealing back cylinder cover 10, open the passage of cylinder protecgulum 5, make compressed air enter cylinder block 7 from the left side, promote piston 9 and move right, the air on cylinder body 7 the right is discharged by the final vacuum hole by the passage of back cylinder cover 10.When piston 9 moved to right near the dead point, lance 16 clashed into reversing valve core 14 again and moves to right, the inlet channel in shifter cylinder 7 left sides.So repeatedly, piston rod 6 is moved back and forth fast, and saw blade 1 is to be fixed on the piston rod leading section by 2 Screws 2, has therefore reached the purpose of work.The leading section of piston rod 6 is contained in the axle sleeve 4, can slide.Piston 4 is equipped with sealing ring 8.Open a straight trough along axis direction on the front end housing 5, lance 16 can slide in groove, prevents the rotation of piston rod like this.Screw 3 is used for fixing other cutters of changing, as file, scraper etc.Can enlarge range of application of the present utility model.
