The utility model belongs to mechanical field.
Many pipelines can be touched in people's daily life, such as water pipe, steam heating pipe etc., especially irony pipeline, owing to limiting by length, tapping must be carried out, namely open internal thread or external screw thread at pipe ends, current tapping has old-fashioned way to be manual, and general employing is less now, major part engineering adopts tapping machine, existing tapping machine is substantially all electronically controlled main equipment, and equipment is huge, complex structure.
Summary of the invention
The purpose of this utility model is to provide a kind of pneumatic tapper being carried out pipe tapping by cylinder, gear conduction.
Cylinder of the present utility model is fixed on riser, the piston rod of cylinder is fixedly connected with slide bar by fixed mount, slide bar is placed on sliding pallet, sliding pallet axle is connected on riser, slide bar is installed with tooth bar, tooth bar and Jie's gears meshing, Jie's gear is coaxially connected with gear wheel by macro-axis, and macro-axis is arranged on riser; Gear wheel engages with pinion, and is clamped by pedestal outside gear wheel and pinion; The axis of pinion is through riser, and the axis other end is provided with tapping-head; Cylinder is connected with air pump by pipeline.
The utility model structure is simple, reasonable in design, by the gear motion between the piston movement of cylinder and gear, drives tapping-head to carry out tapping to pipe.

Detailed description of the invention
Cylinder 7 of the present utility model is fixed on riser 2, the piston rod 10 of cylinder 7 is fixedly connected with slide bar 1 by fixed mount 11, fixing by fixed mount 11, can ensure that piston rod 10 is when seesawing, band moving slide-bar 1 also does and synchronously seesaws, slide bar 1 is placed on sliding pallet 8, sliding pallet 8 axle is connected on riser 2, sliding pallet 8 there is pulley, the bar at center is fixed on riser 2, be enclosed within pulley on bar when slide bar seesaws, reduce the friction (resistance) between slide bar 1 and sliding pallet 8, slide bar 1 is installed with tooth bar 6, tooth bar 6 and slide bar 1 are synchronized with the movement, tooth bar 6 engages with Jie's gear 9, while tooth bar 6 does and seesaws, Jie's gear 9 is driven to rotate, Jie's gear 9 is coaxially connected with gear wheel 3 by macro-axis 13, Jie's gear 9 and gear wheel 3 coaxial, so, while Jie's gear 9 rotates, gear wheel 3 also does coaxial rotating in same direction, and the tooth footpath of the gear 9 that is situated between is less than the tooth footpath of gear wheel 3, macro-axis 13 is arranged on riser 2, macro-axis 13 is axles that Jie's gear 9 and gear wheel 3 share, Jie's gear 9 and gear wheel 3 can be rotated centered by this axle, gear wheel 3 engages with pinion 4, the tooth footpath of gear wheel 3 is greater than the external diameter of pinion 4, when such gear wheel 3 rotates, pinion 4 is driven to carry out antiport fast, and clamped by pedestal 5 outside gear wheel 3 and pinion 4, pedestal 5 is fixed with the pedestal of gear wheel 3 and pinion 4, do not affect the rotation of gear wheel 3 and pinion 4, only play restriction to outside pinion 3 and pinion 4, by the clamping of pedestal 5 and riser 2, minimizing gear wheel 3 and pinion 4 carry out deflection and rotate, and remain engagement, the axis 15 of pinion 4 is through riser 2, and axis 15 other end is provided with tapping-head 14, and the rotation of such pinion 4 drives tapping-head 14 to rotate simultaneously, can carry out screwing operation by needing the pipe of tapping on tapping-head 14, cylinder 7 is connected with air pump 12 by pipeline, air pump 12 is for cylinder 7 provides source of the gas and arrange, air pump 12 can pass through electrical equipment control, be set to air feed, air-breathing back and forth carry out, the piston rod of such cylinder 7 can do drawback movement when reaching at full capacity timely, so just ensures that slide bar also does the reciprocating motion of forward-reverse simultaneously.By above structure, do front-rear reciprocation movement at the supply effect drop shot of source of the gas, tapping is responsible in the motion of forward, and reverse motion is responsible for unloading the pipe of having attacked silk.
