The specific embodiment
Each preferred embodiment of the utility model below will be discussed.But it will be appreciated by those skilled in the art that the detailed description here as to the restriction of the utility model protection domain, the utility model also can be achieved through modification or other equivalent way of following each embodiment.
In an embodiment of the utility model, the shaft device that is used for the pneumatic clamping device of integrated thin-wall pipes comprises pull bar module, rotating shaft shell module and chuck module.
As an example, as shown in Figure 1, the pull bar module can comprise: 1. pull bar knob, 2. pull bar lid, 3. piston bush, 4. draw-bar seat, 5. cover, 6. rolling bearing, 7. axle sleeve, 8. pull bar, 9. tubing, 10. direct driving motor in the piston.The effect of pull bar module is the clamping of realization tubing and unclamps.The pull bar module clamps and the process of unclamping tubing realizes through the cylinder principle.As shown in the figure, the pull bar module is coupling on the mover of the direct driving motor in the shaft device regularly, can be rotated motion with mover.Chuck is then through being screwed into the right-hand member screwed hole of pull bar module from the rotating shaft left end.When the left air cavity of diagram was inflated, high pressure gas cognition was pushing away the pull bar module towards right motion, thereby drive pull bar chuck was strained towards right-hand member; Up to the internal conical surface of the end collar of the outer conical surface of chuck and shaft device left end paste dead till because the chuck of being joined is a collet, this chuck is held the internal conical surface of collar stuck; Bear simultaneously towards right pulling force, cause collet to tighten up, tubing is embraced; Keep this state, tubing will be held tightly by chuck always.In the time of tubing need being unclamped, give right air cavity inflation, left air cavity venting; Gases at high pressure promote piston boit and move towards the left side; Move towards the left side thereby drive pull bar, and then make the outer conical surface of collet and the internal conical surface of holding collar be separated, keep releasing orientation; This moment, collet relied on the elastic-restoring force of self to keep releasing orientation, and tubing is with released.In order to guarantee to adopt the sealing of 0 shape sealing ring between the air-tightness various piece.
In one example, the non-maintaining direct driving motor of high-performance be can adopt, the high speed feed that to realize rotating shaft, the high acceleration and high accuracy it is advantageous that.Motor takes directly to drive the design of joint pin, can omit reduction gearing, therefore can reach the high acceleration and the high accuracy of rotating shaft.Simultaneously, because direct driving motor is built-in, can directly combines with rotating shaft and need not use mechanical attachment device.
Joint pin is connected with direct driving motor through screw, the high-speed rotating shaft drive of rotor and the high speed rotation of the pull bar of joint pin interference fit, and pull bar clamps tubing, thus the high accuracy that realizes tubing is rotated.When pull bar was driven the high accuracy rotation by direct drive motor rotor, rolling bearing was used for tie-strut.Grease supply lubricating bearings can be supported 20000 commentaries on classics/per minutes.
Rotating shaft is a hollow structure inside, can let pull bar pass through from the centre, and the rotating shaft of hollow can be realized tubing conveying function and wet cutting operation function simultaneously.Pull bar be thin-wall seamless pipe and the pull bar internal diameter of hollow greater than tube outer diameter to hold tubing to be processed.Pull bar inside can form annular seal space.Cut when wetting and to add man-hour, adopt rearmounted water guide mode, this moment, whole tubing immersed in the aqueduct, in case aqueduct is revealed, current also are in the hollow sealing chamber of pull bar, can not be leaked to the operate as normal that interior of rotating shaft influences motor.
The chuck module is used for the auxiliary connecting rod module and realizes the clamping of tubing and unclamp.As shown in Figure 1, the chuck module comprises: 11. joint pins, 12. piston boits, 13. springs, 14. nose circles lid, 15. end inner caps, 16, bearing pin, 17. chuck installing rings, 18. end collars, 19. chucks.Collet segment is taked mazy seal form, makes to add man-hour wet cutting, and the water smoke of machining area can not enter into interior of rotating shaft.
Rotating shaft shell module comprises: 20. rear end caps, 21. thin-walled end caps, 22. rotating shaft outer walls, 23. right end caps, 24. mounting seat.Two external tappings are arranged on the shell: one is the encoder lead-out wire, and another is the motor power lead-out wire.In one example, the rotating shaft shell can adopt waterproof material to make, and classification of waterproof IP65 is so that anti-effectively dust and water spatter.Through mounting seat, rotating shaft integral body can be fixed on the linear axis upper mounting plate very easily.Integral body is convenient to install (being installed on the linear axis platform), location.In addition, alignment pin also capable of using is realized coarse positioning.
Can be at the inner sensor installation 25 of pull bar.Like this, wetting when cutting processing technology, if security alarm can be provided when having current to reveal.For example, when there was seepage aqueduct fracture or aqueduct and tubing afterbody junction in the machining area, said sensor sent safety alarm with shut-down operation.Secondly, this sensor also can be discerned metal material and nonmetallic materials, thereby is convenient to the tubing counting, realizes the automatic feed function.
