Description
Affiliated technical field
The utility model relates to a kind of electric main shaft cut cooling system.
Background technology
Lathe is used cutting fluid and is cooled off cutter and workpiece in the course of work of cutting metal, cutting fluid plays cooling, lubricates and assist the function of chip removal in working angles.In the general processing all is from the outside cutting fluid to be sprayed onto cutting zone, because electric speed of mainshaft height, cutting speed is fast, and the time compole that blade contacts with workpiece is short, makes the cutting fluid of outside spray all not enter cutting zone, has influenced the performance of cooling fluid function.
Summary of the invention
The purpose of this utility model is to provide the electric alignment of shafts discharging device of a kind of top feed flow, to solve the problem of electric main shaft cutting cooling.
Technical scheme of the present utility model is summarized as follows:
The electric alignment of shafts discharging device of a kind of top feed flow comprises direct linkage type swivel joint, spacer and straight-through quick connector and O-ring seals, end face O-ring seals, inboard O-ring seals.The direct linkage type swivel joint is connected with the armature spindle of electric main shaft by left hand thread, and spacer is fixed on the bearing block, and straight-through quick connector is connected with the direct linkage type swivel joint by gas thread from the top of electric main shaft.Inboard O-ring seals is housed between direct linkage type swivel joint and the spacer, and the central through hole of straight-through quick connector, direct linkage type swivel joint, armature spindle communicates.
The swivel joint maximum speed can reach 20000r/min, when electric spindle operation, armature spindle drives the axle rotation together of direct linkage type swivel joint, cooling fluid is by leading directly to quick connector in the direct linkage type swivel joint flows to the central through hole of armature spindle, and then be sprayed onto on the workpiece by the hollow cutter, make the function of cooling fluid bring into play better.
The utility model practicality simple in structure, effective has not only effectively guaranteed the cooling of cutting zone, and the chip removal that has realized working angles has improved the durability of cutter and the crudy of workpiece with lubricated.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
In electricity main shaft when cutting,, one of major function of cutting fluid just is that it can take away heat in metal cutting rapidly from the machining area of lathe effectively, thereby reduces the temperature rise of cutting zone, improves the machining accuracy of tool life and workpiece; Another function of cutting fluid is exactly lubricated, after cutting fluid enters cutting region, will penetrate into the contact-making surface of cutter, workpiece, and, form one deck lubricating film, to reduce friction attached on the metal surface, alleviate the bonding phenomenon of smear metal and cutter, help improving the surface quality of workpiece; It is to assist chip removal that cutting fluid also has an effect, and cutting fluid can be dashed tiny chip from workpiece or cutter, is beneficial to improve the machining accuracy of part and the service life of cutter.
In the general processing all is from the outside cutting fluid to be sprayed onto cutting zone, because electric speed of mainshaft height, cutting speed is fast, the time compole that blade contacts with workpiece is short, make the cutting fluid of outside spray can not all enter cutting zone, influenced the performance of above-mentioned cooling fluid function, even and outside hydrojet from different orientation a plurality of points spray also have unavoidably the dead angle dash less than, thereby the effect of chip removal is assisted in influence.If from the cutter inboard cutting fluid directly is sprayed onto cutting point, the above-mentioned functions of cutting fluid will further be brought into play, and for the foregoing reasons, design the electric alignment of shafts discharging device of this top feed flow.
During the cutting of electricity main shaft, cutter is along with armature spindle [8] rotates at a high speed with rotation speed n together, its inner cutting fluid is also along with rotation together, but straight-through quick connector [3] and the water pipe of introducing cutting fluid can't rotate together, so a direct linkage type swivel joint [1] is installed in armature spindle [8] upper end, direct linkage type swivel joint [1] maximum speed can reach 20000r/min, can satisfy the cutting requirement of electric main shaft.
As shown in Figure 1, the electric alignment of shafts discharging device of this top feed flow comprises direct linkage type swivel joint [1], spacer [2], straight-through quick connector [3] and O RunddichtringO [4], end face O RunddichtringO [6], inboard O RunddichtringO [7].Direct linkage type swivel joint [1] is connected on the armature spindle [8] of electric main shaft by left hand thread, and spacer [2] is fixed on the bearing block [10].Straight-through quick connector [3] is connected in the top of direct linkage type swivel joint [1] by gas thread; O RunddichtringO [4] can prevent that foreign matter and greasy dirt from entering the inner bearing [9] that damages of electric main shaft by the installing hole that leads directly to quick connector [3]; Installing end face O RunddichtringO [6] additional also is in order to prevent that foreign matter and greasy dirt are by entering electric main shaft inside in conjunction with the slit; And inboard O RunddichtringO [7] can be done further protection, the more important thing is to prevent that direct linkage type swivel joint [1] from influencing machining accuracy in when work vibration.During the electricity spindle operation, the axle that armature spindle [8] drives direct linkage type swivel joint [1] rotates at a high speed with rotation speed n, and direction of rotation sees it is counterclockwise from bottom to top, and their connecting thread is a left hand thread, so can not occur at work connecting loosening phenomenon, guarantee the reliability of device.
The cooling fluid that has a certain pressure flows in the central through hole of armature spindle [8] through flexible pipe, straight-through quick connector [3], direct linkage type swivel joint [1], and then is sprayed onto on the workpiece by hollow handle of a knife or sealing chuck pressure cap and hollow cutter.Cooling fluid has just been carried out inner cooling to cutter when flowing through the cutter mesopore, can prolong the service life of cutter; When flowing out the outside, certainly will pass through workpiece, again workpiece be cooled off and lubricates; Drive also rotation in ejection of cooling fluid because cutter rotates at a high speed, so the tiny smear metal meeting around the cutter is rushed at the periphery, avoiding smear metal to be bonded at influences machining accuracy and cutter life on cutter or the workpiece.
Claims (2)
1. the electric alignment of shafts discharging device of a top feed flow comprises direct linkage type swivel joint [1], spacer [2], straight-through quick connector [3] and O RunddichtringO [4], end face O RunddichtringO [6], inboard O RunddichtringO [7]; It is characterized in that: direct linkage type swivel joint [1] is connected on the armature spindle [8] of electric main shaft by left hand thread, and spacer [2] is fixed on the bearing block [10], and straight-through quick connector [3] is connected with direct linkage type swivel joint [1] by gas thread from the top of electric main shaft; Install inboard O RunddichtringO [7] additional between direct linkage type swivel joint [1] and the spacer [2]; The central through hole of straight-through quick connector [3], direct linkage type swivel joint [1], armature spindle [8] communicates.
