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.
Cut in the process in that laser is wet, can utilize rearmounted water guide, preposition water guide, with the coaxial water guide of laser beam, and multiple water guide mode such as laser beam disalignment water guide.In an embodiment of the utility model, can adopt rearmounted water guide mode.As shown in Figure 1; Aqueduct in the utility model is a seamless pipe that external diameter is littler than pipe internal diameter to be processed; Aqueduct is connected with water supply module; Import to tubing to be processed inside with the cooling water that will have certain pressure, overflow from tubing, seal with seal plug in tube end for preventing current.Whole tubing is to pass from the interior of rotating shaft of hollow together with aqueduct.Therefore need the inside of rotating shaft is sealed, to prevent aqueduct fracture or aqueduct and tubing afterbody junction seepage is arranged, current get into motor to be influenced the operate as normal of motor or burns out motor.
More specifically, rotating shaft is a hollow structure inside, so that pull bar is passed through from the centre, the rotating shaft of hollow can also be realized tubing conveying function and wet cutting operation function simultaneously.In addition, can the tubing of the rotating shaft that passes hollow entirely be sealed in the pull bar, as shown in Figure 1.Pull bar is the hollow and thin-walled seamless pipe of an internal diameter greater than tube outer diameter, therefore even aqueduct fracture or aqueduct have water to reveal with the tubing junction, current also just leakage in the annular seal space of pull bar, can not be emitted to interior of rotating shaft.In one example, cut processing when adopting rearmounted water guide mode when wet, whole tubing immerses in the aqueduct, even at this moment aqueduct is revealed, current also are to be limited in can not being leaked to the operate as normal that interior of rotating shaft influences motor in the hollow sealing chamber of pull bar.
In an embodiment of the utility model, the clamping of tubing and unclamp through the cooperation of pull bar and clamp part and by the cylinder principle and realize.When left air cavity was inflated, high pressure gas cognition was pushing away pull bar 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 rotating shaft 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.
