Description
Technical field
The utility model relates to a kind of processing unit (plant) of deep hole annular oil groove.
Background technology
The common processing method of deep hole annular oil groove adopts boring machine to utilize radial feeding device to realize the processing of oil groove.
Deep hole annular oil groove is more common on the axial workpieces such as oil cylinder, high especially for the required precision of hydraulic oil pipeline oil groove, for avoiding occurring that stress is concentrated, add and mainly adopt boring machine man-hour, utilize special radial feeding cutting tool, to improve working (machining) efficiency and quality, production cost is high.At present, existing inside holes topping machanism adopts wedge or eccentric to realize radial feed or the adjustment of cutter, its complex structure usually, and mounting and adjusting is more difficult, is difficult to realize disposable porous Continuous maching, inefficiency.Also the radial feeding device utilizing hydraulic system and feed cylinder to realize cutter is had, as the method that CN202684608U announces.Above method all utilizes molding cutter to process, its complex structure, and mounting and adjusting is more difficult, is difficult to the shape and the dimensional accuracy that ensure oil groove, be difficult to meet processing request, and cost is high for the oil groove that required precision is high.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, and aim to provide a kind of structure simple, cost is low, the processing unit (plant) of deep hole annular oil groove convenient to operation.
Implementation of the present utility model is, a kind of processing unit (plant) of deep hole annular oil groove, boring bar seat is fixed on horizontal NC lathe knife rest by alignment pin and bolt one, boring bar bolt two and trip bolt are fixed on boring bar seat for assembling in the hole of boring bar, boring head is threaded with boring bar, and lathe tool to be arranged in the square hole on boring head and to press solidly with housing screw.
During with the utility model deep hole processing annular oil groove, processing work endoporus oral area bore dia is large, make central axle sleeve and be assembled in workpiece oral area endoporus, with the tool setting of workpiece spindle end face, boring bar is with knife rest axial feed, and workpiece rotates, boring bar makes axis and radial feed with knife rest, according to the cross sectional shape figure of annular oil groove, numerical programming procedure, lathe tool is processed annular oil groove; Process rear first radial, more axial withdrawing.Turning adopts four layers of cutting, last cutter skin processing.
The utility model structure is simple, convenient to operation, flexibility strong, can ensure shape and the dimensional accuracy of annular oil groove.

Fig. 1 is the utility model apparatus structure schematic diagram,
Fig. 2 for carry out deep hole annular oil groove processing plane figure with the utility model,
Fig. 3 is the partial enlarged drawing of encircled portion in Fig. 2.
Detailed description of the invention
With reference to the accompanying drawings in detail the utility model is described in detail.
With reference to Fig. 1,2,3, the boring bar seat 2 of the processing unit (plant) of deep hole annular oil groove of the present utility model is fixed on horizontal NC lathe knife rest 1 by alignment pin 4 and bolt 1, boring bar 10 bolt 26 and trip bolt 5 are fixed on boring bar seat 2 for assembling in the hole of boring bar, boring head 9 is threaded with boring bar 10, and lathe tool 7 is arranged in the square hole on boring head 9 and also presses solidly with housing screw 8.On boring bar seat 2, the center of boring bar pilot hole is high consistent with the machine tool chief axis centre of gyration.
The utility model is adopted to be that the endoporus of the processing work 11 of deep hole annular oil groove is stepped hole, and oral area bore dia is greater than the bore dia of oil groove position to the concrete grammar that deep hole annular oil groove is processed.
For ease of tool setting, specially make central axle sleeve 12, sleeve outer circle diameter dimension φ D joins work by workpiece oral area actual measurement internal diameter size φ D1,0.01-0.025mm less of workpiece oral area actual measurement internal diameter.Ensure the outer little 0.01-0.025mm of diameter ratio shaft diameter of bore of central axle sleeve.Shaft shoulder outside diameter size φ C 10 ~ 15mm larger than sleeve outer circle diameter dimension φ D, it is identical that inner hole of shaft sleeve diameter dimension φ d and workpiece oil groove positions place diameter of bore survey size φ d1.
Central axle sleeve 12 is assembled in workpiece 11 oral area endoporus, the tool setting of central axle sleeve 12 endoporus hole surface is pressed during lathe tool tool setting, with the tool setting of workpiece 11 axial end, a kind of boring bar 10 of processing unit (plant) of deep hole annular oil groove is with knife rest 1 axial feed, according to the axial distance numerical value of oil groove position and workpiece 11 end face, move axially knife rest, lathe tool 7 moves to oil groove position vertically.For preventing point of a knife from scratching hole, oil groove place hole surface, vertically during feed, lathe tool 7 point of a knife and oil groove place endoporus hole surface stay 0.1mm gap.Radially and axial feed, workpiece 11 rotates with lathe spindle lathe tool, and boring bar is with knife rest feeding, and according to the cross sectional shape figure of annular oil groove, the conventional common nc program of establishment, lathe tool is processed annular oil groove by procedure.
For ensureing the radial and axial machining accuracy of annular oil groove and surface roughness, reduce in process due to the longer vibration caused of boring bar overhanging, when adopting the utility model turning deep hole annular oil groove, adopt layered cutting, be divided into four layers of cutting, divide equally every layer of cutting depth according to the deep hole annular oil groove degree of depth, control cutting depth and cutting speed, before last cutter, stay 0.1-0.2mm skin processing amount, carry out last cutter skin processing.
After annular oil groove completion of processing during withdrawing, for preventing lathe tool 7 point of a knife from pulling hole surface, first by lathe tool 7 radially withdrawing distance hole, oil groove place hole surface 2 ~ 3mm, then along Z-axis direction withdrawing.The oil groove cross sectional shape processed like this and drawing matching degree high, and oil groove position axial direction distance accuracy high.
The utility model structure is simple, convenient to operation, flexibility strong, can ensure shape and the dimensional accuracy of annular oil groove.
