Description

Modular boring machine

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 the gear-box,, then need successively process each hole if it is processed with general boring machine.Earlier gear-box is placed on the building bed, good with clamps, process first hole then; 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, unclamp anchor clamps this moment earlier, 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 anchor clamps, the processing dimension of adjustment boring cutter is reprocessed second hole.By that analogy, when processing a hole on the gear-box, require a great deal of time, and the common deviation ratio of its processing back precision is bigger.

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; The clamping device that is used for the clamping gear-box is installed on the workbench; But the both sides of said workbench also are provided with the left and right boring device of left and right translation, all convex with the boring cutter axle on the said left and right boring device, and are provided with boring cutter symmetrically on the overhanging end of boring cutter axle.Though; This modular boring machine helps improving working (machining) efficiency, still, and for the clamping device of clamping gear-box; Because there is certain difference in the size of workpiece; And the cutter machining center is fixed with the distance of clamping device, so has certain error between the processed workpiece, causes workpiece accuracy not high.

Summary of the invention

To 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 following:

Modular boring machine, the workbench that comprises the boring machine lathe bed and be positioned at boring machine lathe bed middle part is equipped with the clamping device that is used for the clamping gear-box on the workbench; But the both sides of said workbench also are provided with the left and right boring device of left and right translation; All convex with the boring cutter axle on the said left and right boring device, and be provided with boring cutter symmetrically on the overhanging end of boring cutter axle, said 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 is symmetrical set a pair of clamping device that is positioned at workpiece locating area left side and right side on the base, and each clamping device comprises drive unit; And the anchor clamps that are fixedly connected with drive unit; Said anchor clamps are slidingly fitted in the chute on the base, and a controller that is used to send action command is fixed on base, and the output of controller is electrically connected the drive unit of clamping device.

Adopted such scheme, because symmetrically arranged clamping device is equal apart from the distance of workpiece locating area, and the center between the 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, and the speed that clamping device moves is spent mutually, therefore after workpiece to be machined is held grips; Workpiece to be machined is a benchmark with the workpiece to be machined center adding man-hour all the time; Thereby the tolerance of workpiece to be machined itself is shared by the left and right sides, and the tolerance of its both sides reduces, so the positioning accuracy of workpiece to be machined is improved.

In addition, the present invention can make the cramping body of clamping device move with the mode of sliding through switching driving device, and perhaps the roll mode through the rolling element device makes its motion, can decide as required like this and select concrete manner of execution.Owing to utilize rolling element to realize motion, its major advantage is that its frictional force is little, motion is nimble, is difficult for producing creeping phenomenon; Positioning accuracy is higher, and it is less to rub, 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 helped increasing further the positioning accuracy to workpiece like this.If for requiring the not high workpiece of positioning accuracy, cramping body only need move under common sliding mode and get final product.
