Abstract

The utility model belongs to the technical field of a lathe fitting for mechanical processing, which is used for processing the outer circular slots of parts of the shaft class. The utility model is characterized in that the front and the rear cutter containing slots of a common cutter holder are widened, and two to five special slotting cutters can be surely contained; the cutter holder is provided with twenty-four M12 type screw holes, wherein, the screw holes on the front and the rear cutter containing slots form staggered arrangement to ensure that the slotting cutters can be tightly clamped at any position. Compared with gang cutters in some factories, the utility model has the advantages of convenient adjustment and operation, simple cutters, low fabrication cost, low worker's technical quality requirement and high efficiency.

Description

Multifunctional lathe tool post

The utility model belongs to machining lathe accessories technical field, is used for the outer garden groove of working shaft-like part.

The engine lathe knife rest adopts the square pattern of side direction dress cutter at present, and every side only can be adorned one on cutter, adorns four on cutter altogether, and each feeding is used one, and its excess-three handle is selected in withdrawing knife rest transposition then.The part grooving that this knife rest is concentrated for the outer garden of axle class groove, clamping workpiece often, the transposing cutter is frequent, the part quality instability, workman's technical quality requires high, and work efficiency is extremely low, waste a large amount of cutter hub materials, be not suitable for the outer garden groove of working shaft-like part in enormous quantities.

In the groove process of garden, cutter is arranged in use outside motor skiving axle in south dynamic power machine company.But complex manufacturing technology, the expense costliness, and it is radially all fixing with axial dimension to piece together back row's cutter, can not adjust, not only dimensional tolerance is little, and size is interfered mutually during making, can not reface with blunt back cutter, scrap wherein one cutter, cause whole row's cutter to be scrapped, waste a large amount of high speed steel and product man-hour.Adopt the numerically controlled lathe grooving, though cutter energy automatic displacement, index time is long, and the cutter compensation error is big, and feed speed is wayward, destroys grooving cutter easily.Be not suitable for the processing of the outer garden of minor axis class in enormous quantities groove.

The purpose of this utility model provides a kind of multi-purpose machine knife rest, makes engine lathe be suitable for the processing of the outer garden of many specifications minor axis in enormous quantities groove, realize multiple cut, and the dress cutter is easy to adjust.

The technical solution of the utility model is: the front and back knife holder slot of plain cutter holder is widened, guaranteed to hold 2-5 special-purpose grooving cutter.Left and right sides knife holder slot keeps the width of plain cutter holder, and groove is to the lathe tool of adorning a big cutting data.24 M of the top layout of knife rest ₁₂Screw hole, wherein before and after screw interlaced arrangement above the knife holder slot, to guarantee that grooving cutter can both clamp in any position.The hole of the middle part retainer belt taper key groove of knife rest guarantees that knife rest is fixedly clamped on lathe carriage, and processing four calibration keyways in bottom surface are accurately to locate after the assurance transposition.

Fig. 1 is the utility model front view.

Fig. 2 is the utility model vertical view.

Fig. 3 is the utility model work schematic diagram.

Knife rest (3) is fastened on the lathe carriage by axle (2) and clamping transposition handle (1), and standard axle (6) clamping is used M behind the aligning in knife holder slot ₁₂Hexagonal sunk screw (4) is fastening.The dress cutter finishes, and the lathe saddle is fixed on the body of lathe bed, takes away standard axle like this and changes part to be processed, need only accurately grasp the amount of feeding of middle carriage, gets final product so that the outer garden groove time processing of part is come out.Can drive the knife rest transposition when unclamping clamping transposition handle (1), use its excess-three knife holder slot.(5) be lathe tool.

Inclined to one side grooving cutter about special-purpose grooving cutter is equipped with respectively do not interfere to realize different axial dimension grooves processing fashionable dress cuttves, and length overall is consistent so that certain regulated quantity is radially arranged.About inclined to one side 45 ° of special-purpose lathe tools, can satisfy the requirement that chamfering and light end face are got length overall.These cutters all adopt the common straightcarbon steel material to do cutter hub, do cutter head with the YT15 carbide chip, with the raising tool life, and the long 60mm of cutter, it is fixed that thick 10-20mm, height and thickness look the workpiece size.

Convenient for tool calibra-tion, produce standard by part to be processed during actual the use, save the adjustment time.

The utility model has been realized the function of rack cutting on engine lathe, kept the repertoire of former plain cutter holder again.The groove processing of the outer garden of axle class is compared with engine lathe knife rest grooving, and efficient improves 2-5 doubly, saves the time and the adjustment time of clamping workpiece, can guarantee the unification of every batch of accessory size, is adapted to produce in enormous quantities.

The utility model is compared the work efficiency height with row's cutter of some factory, and adjusting operation is convenient, and the simple manufacturing expense of cutter is low, and workman's technical quality requires low, is suitable for the machining of big-and-middle-sized machinery plant Short Axis Kind streamline China and foreign countries garden groove. The utility model used so far at our factory from August, 92, and is functional, reaches designing requirement, and it makes profits 44.02 ten thousand yuan.

Claims

1, a kind of multi-purpose machine knife rest is characterized in that the front and back knife holder slot of plain cutter holder is widened, and guarantees to hold 2-5 special-purpose grooving cutter, arranges 24 M above the knife rest ₁₂Screw hole, wherein before and after screw interlaced arrangement above the knife holder slot, to guarantee that grooving cutter can both clamp in any position.
