Description
Technical field
The invention belongs to Automated assembly technical field, more particularly to a kind of anti-sticking screwdriver bit.
Background technology
In the stud nut of electric type automotive-type product shell wire harness etc., traditional production line is filled by common screwdriver bit
On tighten rifle assembling.Card is difficult to ensure with the quality stability for being continuously increased, manually producing of recruitment cost.In the spanner of nut
Situations such as position size material is handled, common screwdriver bit tightens inefficiency, easily produces and blocks when tightening, and moment of torsion is excessive to cause report
It is alert, so that influence productive temp is damaged and tightens rifle, cause bigger unnecessary cost.
The content of the invention
The present invention provides a kind of anti-sticking screwdriver bit, to solve the situation that existing screwdriver bit is blocked when tightening.
A kind of anti-sticking screwdriver bit, the screwdriver bit head of the screwdriver bit has middle cavity, and the hollow intracavitary is provided with a screwdriver bit air bag, batch
Cavity is connected with the middle cavity having in the middle part of screwdriver bit in head portion,
Cavity has tail end gas baffle plate in the middle part of screwdriver bit,
A universal gas-tpe fitting is provided with the middle part of screwdriver bit, the universal gas-tpe fitting one end is connected with the middle cavity in the middle part of screwdriver bit,
The other end connection air pump equipment of universal gas-tpe fitting.
Crack on the screwdriver bit head that screwdriver bit head has axial direction.
The present invention is different from traditional screwdriver bit and carries out nut assembling, and tensioning power tightens screwdriver bit.The quality of screwdriver bit is high, work effect
Rate is high, success rate is high.
Brief description of the drawings
Fig. 1 is anti-sticking screwdriver bit appearance schematic diagram of the present invention.
Fig. 2 is anti-sticking screwdriver bit front view of the present invention.
Fig. 3 is L-L profiles in Fig. 2.
Wherein, 1 --- screwdriver bit body, 2 --- universal gas-tpe fitting, 3 --- screwdriver bit head, 4 --- screwdriver bit air bag,
5 --- tail end gas baffle plate, 6 --- crack on screwdriver bit head.
Embodiment
The present invention needs to install air bag in screwdriver bit head design, installs universal gas-tpe fitting, then installs tail end and stops
Gas block panel.
As shown in Figures 2 and 3, anti-sticking screwdriver bit of the invention, the screwdriver bit head of the screwdriver bit has middle cavity, the hollow intracavitary
Provided with a screwdriver bit air bag, cavity is connected with the middle cavity having in the middle part of screwdriver bit in screwdriver bit head, and cavity has tail in screwdriver bit middle part
Hold and a universal gas-tpe fitting is provided with the middle part of gas baffle plate, screwdriver bit, the universal gas-tpe fitting one end connects with the middle cavity in the middle part of screwdriver bit
It is logical, the other end connection air pump equipment of universal gas-tpe fitting.Crack on the screwdriver bit head that screwdriver bit head has axial direction.
Tighten before screwdriver bit tightens to nut, source of the gas gives gas universal gas joint, and then air bag air inlet causes screwdriver bit to expand, tightened
Rifle and the universal gas-tpe fitting rotation of screwdriver bit are tightened, and in place, source of the gas return-air, deflated balloon, screwdriver bit diminishes screw-down torque, exits nut
Spanner position.
