The specific embodiment
Each preferred embodiment of the present utility model below will be discussed.But it will be appreciated by those skilled in the art that herein detailed description as to the restriction of the utility model protection domain, the utility model also can be achieved by modification or other equivalent way of following each embodiment.
In an embodiment of the present utility model, the shaft device that is used for integrated thin-wall pipes Pneumatic clamping mechanism comprises pull bar module, rotating shaft shell module and chuck module.
As 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. piston inner sleeve, 6. rolling bearing, 7. axle sleeve, 8. pull bar, 9. tubing, 10. direct driving motor.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 by 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 by being screwed into the right-hand member screwed hole of pull bar module from the rotating shaft left end.When the left air cavity inflation of diagram, high pressure gas cognition is pushing away the pull bar module towards right motion, thereby drive pull bar chuck is strained towards right-hand member, until the subsides of the internal conical surface of the end collar of the outer conical surface of chuck and shaft device left end are dead, because the chuck of joining is collet, this chuck is held the internal conical surface of collar stuck, bear simultaneously the pulling force towards the right side, cause collet to tighten up, tubing is embraced, keep this state, tubing will be held tightly by chuck always.In the time of need to unclamping tubing, give right air cavity inflation, left air cavity venting, gases at high pressure pushing piston post moves towards the left side, move towards the left side thereby drive pull bar, and then so that the outer conical surface of collet is separated with the internal conical surface of holding collar, keep releasing orientation, this moment, collet relied on the elastic recovery force retaining releasing orientation of self, 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 high acceleration and the high accuracy of rotating shaft.Simultaneously, because direct driving motor is built-in, can need not use mechanical attachment device with the direct combination of rotating shaft.
Joint pin is connected with direct driving motor by screw, the high-speed rotating shaft drive of rotor and the High Rotation Speed of the pull bar of joint pin interference fit, and pull bar clamps tubing, thereby realizes the high-precision rotary of tubing.When pull bar was driven high-precision rotary by direct drive motor rotor, rolling bearing was used for tie-strut.Grease supply lubricating bearings can support 20000 to turn/per minute.
Rotating shaft is the structure of inner hollow, can allow 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 the thin-wall seamless pipe of hollow and pull bar internal diameter 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 normal operation that interior of rotating shaft affects motor.
As shown in Figure 1, the chuck module can comprise: 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.In an embodiment of the present utility model, nose circle lid, end inner cap, end collar and chuck form the labyrinth sealing form.As shown in the figure, nested against one another between nose circle lid and end inner cap, end inner cap and end collar and end collar and the chuck.In addition, also the rubber o-ring sealing can be adopted in each junction of above-mentioned parts.So, can prevent that sealing enters into interior of rotating shaft from these deathtraps.By taking mazy seal form, can be so that add man-hour wet cutting, the water smoke of machining area can not enter into interior of rotating shaft.
As example, rotating shaft shell module can comprise: 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 motor power outgoing line.In one example, the rotating shaft shell can adopt waterproof material to make, and classification of waterproof IP65 is so that anti-dust and water spatter effectively.By mounting seat, shaft device can be mounted and fixed on the linear axis platform very easily.Thereby be convenient to installation (being installed on the linear axis platform), the location of device integral body.In addition, also can utilize alignment pin, realize the location of shaft device.
In one example, can be in the inner annular seal space that forms of pull bar sensor installation 25.Like this, wetting when cutting processing technology, if can provide security alarm when having current to reveal.For example, when there was seepage aqueduct fracture or aqueduct in the machining area and tubing afterbody junction, described sensor sent safety alarm with shut-down operation.Secondly, this sensor also can be identified metal material and nonmetallic materials, thereby is convenient to the tubing counting, realizes the automatic feed function.
