Description
Technical field
The present invention relates to the Machining Technology for Cutting field, be specifically related to a kind of modular boring machine.
Background technology
Usually there are a plurality of holes to need processing on gear-box, if with general boring machine, it is processed, need successively to process each hole.First gear-box is placed on the building bed, fixes with fixture, then process first hole; After processing, regain boring cutter, whether the aperture error of measuring processing reaches request, if do not reach, and the processing dimension of adjustment boring cutter, processing again; Then process second hole, first unclamp fixture this moment, the carrier wheel case, and with the pivot of second the hole fine registration boring cutter that will process, to guarantee the centre-to-centre spacing between two holes, after clipping with fixture, the processing dimension of adjustment boring cutter is reprocessed second hole.By that analogy, require a great deal of time when processing a hole on gear-box, and after its processing, the common deviation ratio of precision is larger.
The modular boring machine that is used for working gear-box, the workbench that comprises the boring machine lathe bed and be positioned at boring machine lathe bed middle part, clamping device for the clamping gear-box is installed on workbench, but the both sides of described workbench also are provided with the left and right boring device of left and right translation, all convex with the boring cutter axle on described left and right boring device, and be provided with symmetrically boring cutter on the overhanging end of boring cutter axle.Although, this modular boring machine is conducive to improve working (machining) efficiency, but, for the clamping device of clamping gear-box, because there is certain difference in the size of workpiece, and the tool sharpening center is fixed with the distance of clamping device, therefore has certain error between the workpiece after processing, causes workpiece accuracy not high.
Summary of the invention
For above-mentioned technical problem, the purpose of this invention is to provide a kind of modular boring machine that can improve the clamping workpiece precision.
The technical scheme that realizes the object of the invention is as follows:
modular boring machine, the workbench that comprises the boring machine lathe bed and be positioned at boring machine lathe bed middle part, clamping device for the clamping gear-box is installed on workbench, the both sides of described workbench also are provided with can be left, the left side of right translation, right boring device, a described left side, all convex with the boring cutter axle on right boring device, and be provided with symmetrically boring cutter on the overhanging end of boring cutter axle, described clamping device comprises base, the central region of base is the workpiece locating area, base is provided with the chute that is positioned at workpiece locating area left side and right side, also be symmetrical arranged a pair of clamping device that is positioned at workpiece locating area left side and right side on base, each clamping device comprises drive unit, and the fixture that is fixedly connected with drive unit, described fixture is slidably fitted in chute on base, one is fixed on base for the controller that sends action command, the output of controller is electrically connected to the drive unit of clamping device.
adopted such scheme, because the distance of symmetrically arranged clamping device apart from the workpiece locating area equates, and the center between symmetrically arranged clamping device is identical with the center of workpiece to be machined, in the course of the work, symmetrically arranged clamping device is controlled by same controller, the speed that clamping device moves is spent mutually, therefore after workpiece to be machined is held mechanism's clamping, workpiece to be machined is adding man-hour all the time take the workpiece to be machined center as benchmark, thereby the tolerance of workpiece to be machined itself is shared by the left and right sides, the tolerance of its both sides reduces, therefore the positioning accuracy of workpiece to be machined is improved.
In addition, the present invention can make the cramping body of clamping device move in the mode of sliding by switching driving device, and perhaps the roll mode by the rolling element device makes its motion, can decide as required like this and select concrete manner of execution.Realize motion owing to utilizing rolling element, its major advantage is that its frictional force is little, motion is nimble, be difficult for producing creeping phenomenon, positioning accuracy is higher, rubs less, and the life-span is long lubricated simple, therefore, when workpiece was needed hi-Fix, the mode that can switch to the rolling element device was moved, and was conducive to like this increase further the positioning accuracy to workpiece.If for requiring the not high workpiece of positioning accuracy, cramping body only need to move under common sliding mode and get final product.
