Abstract
The utility model relates to a digital control screw bolt milling machine, in particular to a tail block specially used for digital control milling machines of spiral rotors. The technical solution of the tail block is characterized by comprising a tail block upper body, a tail block main shaft hole, a tail block lower body and a locking screw bolt, wherein the tail block main shaft hole is arranged on the tail seat upper body, the bottom of the tail block upper body is connected with the tail block lower body, the tail block lower body is installed on a machine tool through the locking screw bolt, one side of the tail block upper body is provided with a cam-ring chuck, the inner hole of the cam-ring chuck is the same with the tail block main shaft hole, and the tail block main shaft hole is the same with the inner hole of the main shaft of a digital control bolt milling machine. The tail block has the beneficial effects that the structure is simple, an existing digital control milling machine of spiral rotors is modified into the milling machine which can process multiple types of rotors, the processing ability of the machine tool is improved, and the economical benefit is improved.
Description
One, technical field:
The utility model relates to a kind of numerical-control screw rod milling machine, the special-purpose tailstock of particularly a kind of digital control helical rotor milling machine.
Two, background technology:
The rotor of screw pump and screw drill is the important part in the instrument of oil field, and complex structure, and machine tool equipment can't be finished the processing to them, needs special numerical-control screw rod milling machine.Be with top on the existing numerical-control screw rod milling machine tailstock, withstand in the tail end centre bore of rotor blank material, front end is tightened by chuck, the rotor length that processes like this is subjected to the restriction of lathe bed length, maximum machining length 4.4m, because product constantly updates, it is long that the length requirement of processing rotor reaches 5-6m, like this, original numerical-control screw rod milling machine is just undesirable.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of special-purpose tailstock of digital control helical rotor milling machine that can process longer rotor is provided.
Its technical scheme is: comprise tailstock upper body, tailstock spindle hole, tailstock lower body and clamping screw, the tailstock upper body is provided with the tailstock spindle hole, the bottom of tailstock upper body connects the tailstock lower body, the tailstock lower body is installed on the lathe bed by clamping screw, one side of described tailstock upper body is installed scroll chuck, the endoporus of scroll chuck is identical with the tailstock spindle hole, and described tailstock spindle hole is identical with the main shaft endoporus of numerical-control screw rod milling machine.
With the top scroll chuck that changes into, the effect of scroll chuck is identical with top effect, so just can process the rotor of being longer than numerical-control screw rod milling machine lathe bed.
The beneficial effects of the utility model are: simple in structure, with existing digital control helical rotor milling machine repack into can processing multiple types rotor, improved the working ability of lathe, improved economic benefit.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representations before the longer rotor of the utility model processing connects cutter;
Accompanying drawing 3 be the longer rotor of the utility model processing connect behind the cutter structural representation;
Among the last figure: claw 9, scroll chuck 10, lathe bed 11, tailstock spindle hole 12, clamping screw 13, tailstock upper body 14, tailstock lower body 15 behind headstock bottom 1, rotor blank material 2, main shaft endoporus 3, milling machine spindle 4, headstock top 5, chuck 6, the preceding claw 7 of hydraulic pressure, facing cutter 8, the hydraulic pressure.
Five, the specific embodiment:
1-3 in conjunction with the accompanying drawings, the utility model will be further described:
With reference to accompanying drawing 1, the utility model comprises tailstock upper body 14, tailstock spindle hole 12, tailstock lower body 15 and clamping screw 13, tailstock upper body 14 is provided with tailstock spindle hole 12, the bottom of tailstock upper body 14 connects tailstock lower body 15, tailstock lower body 15 is installed on the lathe bed 11 by clamping screw 13, one side of described tailstock upper body 14 is installed scroll chuck 10, and the endoporus of scroll chuck 10 is identical with tailstock spindle hole 12, and described tailstock spindle hole 12 is identical with the main shaft endoporus of numerical-control screw rod milling machine.
With reference to accompanying drawing 2-3, mainly form on the lathe bed 11 of numerical-control screw rod milling machine by claw 9 and lathe bed 11 behind claw 7, facing cutter 8, the hydraulic pressure before headstock bottom 1, rotor blank material 2, main shaft endoporus 3, milling machine spindle 4, headstock top 5, chuck 6, the hydraulic pressure.During use,, rotor blank material 2 are installed with reference to accompanying drawing 2 when the rotor length of processing during greater than 4.4m, be provided with main shaft endoporus 3 and milling machine spindle 4 between headstock bottom 1 and the headstock top 5, begin processing from right to left, when being worked into about 2.2m, the parking withdrawing is write down X, the Y of this moment, the value of Z.At this moment, before the hydraulic pressure behind claw 7 and the hydraulic pressure claw 9 hold rotor blank material 2 tightly and do not unclamp.Unclamp the chuck 6 of front end and the scroll chuck 10 of tailstock, before the hydraulic pressure behind claw 7 and the hydraulic pressure claw 9 hold rotor blank material 2 tightly and move right (as Fig. 3) with facing cutter 8 integral body, this moment the rotor blank material with hydraulic pressure front and back claw between any relative motion can not be arranged.Rotor blank material 2 processing part passes in tailstock spindle hole 12, outside the rotor of having processed, put on the thin-walled cover of a band opening, the internal diameter of thin-walled cover is than the big 0.2-0.4mm of the rotor diameter of having processed, and the scroll chuck 10 on the tailstock is by chucking thin-walled cover chucking rotor.Centering also tightens chuck 6 on the numerical-control screw rod milling machine headstock, in the X, the Y that write down, Z value input control panel display panel.Start continues processing, and we are called " connecing cutter " this process, by twice or three times " connecing cutter ", just can process the rotor of any desired length, has improved the working ability of lathe greatly.
