By more visible to Fig. 7 (a) and Fig. 7 (b), the main shaft of same specification, the internal withdraw type spindle nose 97(that the fore bearing radial ball bearing 104 of the spindle nose 105 that tradition overhangs and front axle journal are significantly smaller than the reinforced main tapping of the utility model is shown in Fig. 7 (a)), and the spindle taper hole 106 for erecting tools extends forward, strengthen the length that overhangs of the spindle nose 105 overhanging, made to cut rigidity and reduce.
Taking Z3050 specification as example, by the bearing capacity comparison of two kinds of main tappings that main shaft adopts, see the following form:
Result shows, the radial drilling machine of the unique innovation of the utility model electromechanical integration, have increase performance, designs simplification, Yi Zao, should use, the feature of energy-conservation, easy manipulation, specific as follows:
One, complete machine external form changes
The upper and lower side bus of rocking arm is hyperbola, and traditional is the type of raising up.See Fig. 1.Because hyperbola can reduce the height of rocker-arm way in space, thus the height of increase column root, in order to increase the rigidity of column.
Two, on radial drilling machine, adopt two-speed motor
Adopt two-speed motor to realize the switching of main transformer speed high and low rotating speed, both can increase speed change class, time saving and energy saving again, press push button moment.The utility model is in most of service time like this, and while loading below 70%, (boring exists
when lower), the green energy conservation gear work that available horsepower is 2.2kw.When meeting when load surpasses 70%, (boring exists
when above), then to select power be the powerful gear work of redness of 2.8kw.Can avoid like this using all the time under high power state working, to reach the effect of energy-conservation, reduction of discharging, low-carbon (LC), and flexible operation, one touch existing.
Three, adopt ripe packaged reducer technology
The inner column of radial drilling machine, outer column clamp and rocking arm clamps, traditional hydraulic clamp complex structure, and the utility model adopts ready-made packaged reducer technology, realizes the clamping at above-mentioned two positions, simple, reliable, easily manufactures.See Fig. 2, Fig. 3.
Four, adopt the mature technology of electromagnetic clutch
(1) the utility model adopts four of electromagnetic clutch, and three electromagnetic clutch of employing are switched in the rotating of main transformer speed, are respectively: forward, brake, reversion.The course of work: when forward electromagnetic clutch connection work, brake and the power-off of reversion electromagnetic clutch.In the time that instruction is reversion work, when the power-off of forward electromagnetic clutch, brake electric magnet clutch is connected power-off after 0.3 second, main shaft can moment reduction of speed, parking, the work of reversion electromagnetic clutch, realizes reversion.Electromagnetic clutch is all interlocked action in an integrated package, and whole action completed (capable of regulating) in 0.3～0.5 second, and this structure replaces the rotating that former whole hydraulic system completes to switch action, sees Fig. 4.
(2) journey is determined in boring, tapping switching and boring, tapping, because feeding and rotating all adopt electromagnetic clutch to complete, the utility model is established one stroke switch on feeding dial, when main shaft work feed is during to desired depth, the travel switch set up of collision: 1. in the time that change-over switch is adjusted to boring work and keeps off, the power-off of feeding electromagnetic clutch, main shaft is feed-disabling, manually retracted (main shaft still rotates), sees Fig. 4, Fig. 5.2. in the time that change-over switch is adjusted to tapping work gear, at once start three electromagnetic clutch of main transformer speed, main shaft reversion is return automatically.This structure had both replaced the machinery of radial drilling machine complexity in decades to determine journey structure, had increased again self-tapping retraction newly.
Five, improve feeding insurance and radial up-down safeties
Two place's safeties all adopt manual adjustment friction plate, simple in structure, reliable, with simple Dai Fan.See Fig. 5, Fig. 6.
Six, adopt strength principal axis header structure
The utility model adopts the powerful main-shaft head structure of internal withdraw type, replaces traditional exposed main-shaft head structure.Because spindle nose adopts 3182113 conical bore double row cylindrical rollers, make to be reduced in fore bearing in instrument cone tail, so reduce the length that overhangs of main shaft and instrument, greatly increase the cutting rigidity of main shaft, improve the machining accuracy of lathe.The use that the more applicable mold manufacturing industry of lathe and ground tackle are manufactured, is shown in Fig. 7.
