The device comprises a large-size boring-milling machine and a profiling device arranged on one side of the large-size boring-milling machine and is characterized in that a dovetail slideway device is arranged on a workbench of the boring-milling machine; a sliding block is arranged at the upper part of the dovetail slideway device; brackets are arranged on two sides of the sliding block; pressing shoes are arranged on the brackets and are used for fastening a workpiece through jackscrews; a cutter rod shaft penetrates through the workpiece; one end of the workpiece is supported at the tail of the cutter rod shaft, and the other end of the workpiece is supported into a main shaft of the boring-milling machine; the cutter rod shaft is provided with a cutter disk; a boring cutter head is fixedly clamped on the cutter disk; the sliding block is fixedly connected with a connection plate on the profiling device; the other end of the connection plate is freely connected with an arc elongated notch in the template device through a roller mechanism; the template is fixedly connected with a fixing bracket; the workpiece fixed on the workbench is driven by the workbench to drive a dovetail slideway to move in the axial direction; the sliding block is driven by the connection plate to move in the radial direction; and the cutter rod shaft is driven by the main shaft of the boring-milling machine to rotate.
Description
Technical field
The utility model relates to the processing unit (plant) of major diameter curve bend inner chamber, relates in particular to the processing and manufacturing of metallurgical crystallizer large round billet inner water sleeve.
Background technology
Disk crystallizer inner water sleeve is a vitals in the crystallizer assembly, it is set in the outside of crystallizer copper pipe and the gap certain with the gabarit maintenance of copper pipe, form a fixing water seam, guarantee that the cycle of higher pressure cooling water passes through equably, make the crystallization copper pipe absorb equably the heat of the molten steel in copper pipe, in order to make molten steel form the protegulum of equal thickness in condensation process.In view of the equal non-straight length of the jacket pipe of crystallizer and copper pipe, be all the bend pipe with certain radian, so difficulty of processing is very large.Although varied about the processing method of crystallization water jacket device both at home and abroad, be to adopt Digit Control Machine Tool to process the method with different circular sections bus on the cylindrical pipe pipe to realize basically.Its shortcoming is that the process-cycle is long, cost is high, machining accuracy is low and is yielding, especially major diameter round mold inner water sleeve.In order to overcome these shortcomings, the truning fixture that the inventor had once designed a kind of copying device feeding and had a swivelling tool-holder is realized the turning processing of this special workpiece.But this device is only applicable to the workpiece of diameter less, but can't realize for the processing of large diameter curve bend.
Summary of the invention
Goal of the invention of the present utility model; be to overcome the shortcoming that existing processing unit (plant) can't adapt to major diameter curve bend inner chamber processing needs, propose a kind of boring and milling machine that utilizes and realize the device of major diameter curve bend inner chamber boring-mill work in conjunction with the master form mechanism that is positioned at the one side.
The technical solution of the utility model is achieved in that
A kind of major diameter curve bend inner chamber pattern processing unit (plant), comprise a large-scale boring and milling machine and the copying apparatus that is positioned at a side, it is characterized in that: the workbench of boring and milling machine is provided with the dovetail runner device, its top is with slide block, carriage is equipped with in the slide block both sides, pressure shoes is housed on carriage, pressure shoes is by the fastening workpiece of jackscrew bar, there is cutter spindle to pass through in workpiece, the one end is supported on cutter spindle tail support frame, the other end is supported in the main shaft of boring and milling machine, on described cutter spindle, cutterhead is housed, clamping cutter head on cutterhead; Described slide block is fixedly connected with connecting plate on copying apparatus, and the other end freely is connected with the arc long rabbet of template by roller mechanism, and template is fixedly connected with support; The workbench of boring and milling machine drives the dovetail slideway device and does axially-movable; Slide block moves radially constrained motion by the connecting plate band; Described cutter spindle is rotated by the main shaft drive of boring and milling machine.
Described cutterhead is fixed on cutter spindle by the cutterhead clamp nut.
Compared with prior art, advantage of the present utility model is apparent, is mainly manifested in:
(1) be suitable for the inner chamber processing of large diameter bent-tube boiler straight length, easy and simple to handle, machining accuracy is high.
(2) utilize existing equipment to carry out technological improvement, simple in structure, be easy to realize.
