Description
Technical field
The present invention relates to a kind of machine tool accessory, the disassembly mechanism that a kind of tailstock tool is top.
Background technology
Along with industries such as automobile, internal combustion engine, Aero-Space, shipbuilding, military project household electrical appliances, universal machine, pump valve industry, decelerators
Develop rapidly the continuous progress with high speed machining, automaticity, reliability and the use to lathe of the domestic each relevant industries
The requirement in life-span improves constantly.For some lathes needing processing longaxones parts (such as piston rod, gear shaft),
Generally requiring during finishing and use tailstock to improve machining accuracy, tailstock centre is the key components of tailstock, in process
In usually need to change, the convenience that the life-span of tailstock centre and tailstock centre are changed, directly affect the automaticity of lathe
Reliability with complete machine.And for traditional tailstock tool, the end of its tailstock centre is reserved with screw thread and nut, use process
In can only by workman's manual rotation nut and by tailstock centre dismantle, the mode of this manual teardown tailstock centre is the most time-consuming takes
Power, and screw thread is easy to wear, causes tailstock centre to be continuing with, and reduces automaticity and the reliability of lathe, increases
The later stage use cost of user.
Summary of the invention
The technical problem to be solved is: for the deficiencies in the prior art, it is provided that the demountor that a kind of tailstock tool is top
Structure, tailstock centre can conveniently and efficiently be dismantled by this disassembly mechanism, improves lathe and changes the efficiency of tailstock centre, thus improves
The automaticity of lathe and reliability, increase lathe service life, reduces client's use cost.
The present invention solves the technical scheme that above-mentioned technical problem used: the disassembly mechanism that a kind of tailstock tool is top, including set
Cylinder and be set in the tailstock body outside described sleeve, the front end of described tailstock body is installed with the first end cap, in described sleeve
It is provided with mandrel, the first push rod, the second push rod, piston and sealing lid, if described mandrel is fixed on described by dry bearing
In sleeve, offer in described mandrel and be sequentially connected logical the first inner chamber, the second inner chamber and the 3rd inner chamber, the first described top
Bar is positioned in the second described inner chamber and coordinates with described mandrel small-gap suture, the first described push rod by some holding screws with
Described mandrel is connected, and the outside of the first described push rod is provided with and the described corresponding clamp screw in some holding screw positions
Nail axial channel, the end of one of them described holding screw extend in described holding screw axial channel, and described the
One end of two push rods extend in the 3rd described inner chamber, and the other end of the second described push rod is connected with described piston thread,
The described outside sealing in lid is fixed on described sleeve and being set in the second described push rod, the rear end of described sleeve is fixed
Having the second end cap, the second described end cap to be set in the outside of tailstock centre, the front end of described sleeve is installed with the 3rd end cap,
Described sleeve, sealing are covered and are formed with the first oil pocket between piston, are formed between described sleeve, piston and the 3rd end cap
Second oil pocket, described piston is provided with and is respectively connected with, with the first described oil pocket and the second described oil pocket, the oil transportation hole that leads to,
Described oil transportation hole is connected with extraneous oil pump, and during tailstock work, tailstock centre is embedded in the first inner chamber and tailstock centre and first
Have between push rod between the first gap, the first push rod and the second push rod and there is the second gap, described holding screw axial channel
Length more than the degree of depth in described the first gap, described tailstock body is provided with for the movement travel of described sleeve is entered
The position-limit mechanism of row regulation, the first described gap and the degree of depth sum in the second described gap are less than the maximum fortune of described sleeve
Dynamic stroke.
After the present invention installs, being arranged on by tailstock centre in the first inner chamber, in the course of work, the fluid of extraneous oil pump is through oil transportation hole
Enter in the first oil pocket or the second oil pocket, promote sleeve together with the 3rd end cap, piston, sealing lid, the second push rod, mandrel and the
Two end caps move forward and backward, and then drive tailstock centre to move forward and backward.In second oil pocket during oil-feed, sleeve travels forward, by limit
The movement travel of sleeve is limited to minimum by position mechanism, and when sleeve moves forward to extreme position, (now tailstock centre is in work
Position) time, make the first push rod can not contact with the afterbody of tailstock centre, the first push rod and the second push rod can not contact (even if tail
Have between the first gap, the first push rod and the second push rod between top and the first push rod of seat and there is the second gap), so can ensure
Tailstock can normally work, and when tailstock works, mandrel is together with bearing with tailstock centre high-speed rotation, carries out workpiece
Processing；When needs take off tailstock centre, again by position-limit mechanism, the movement travel of sleeve is limited to maximum stroke movement,
Sleeve moves forward together with the 3rd end cap, piston, sealing lid, the second push rod, mandrel and the second end cap and covers this
During big movement travel, the equal vanishing of the degree of depth in the first gap and the second gap, the second push rod promotes the first push rod to be moved rearwards by,
First push rod pushes up pressure tailstock centre again, and guiding and position-limiting action are played in the movement of the first push rod by holding screw axial channel, and tight
More than the setting of the degree of depth in the first gap, the length determining screw axial guide groove can ensure that the first push rod can push up pressure tailstock centre, again may be used
Preventing the first push rod to tailstock centre top degree of pressing through, tailstock centre ejects smoothly the most at last, it is achieved the purpose dismantled by tailstock centre.
After tailstock centre dismounting, if desired it is reinstalled tailstock centre, only needs first to be arranged in the first inner chamber by tailstock centre, then by oil
Liquid inputs in the first oil pocket, promotes sleeve to drive the 3rd end cap, piston, sealing lid, the second push rod, mandrel and the second end cap one
Playing rearward movement, when the operating position of sleeve rearward movement to tailstock centre, the first gap, the degree of depth in the second gap are recovered again
Initial value, the first push rod does not contacts with the afterbody of tailstock centre, the first push rod and the second push rod do not contact, and tailstock can start normally
Work.The top process of above-mentioned dismounting, mounted tailstock is convenient, safe efficient, is conducive to improving lathe and changes tailstock centre
Efficiency, thus improve automaticity and the reliability of lathe, increases lathe service life, reduces client's use cost.
Described position-limit mechanism be arranged between the front end of described tailstock body and the first described end cap and with the front end of tailstock body and
