Abstract
The Present invention discloses method for maintaining a sleeve barrel of a special machine tool controlled numerically. The method mainly comprises the steps that a tail seat and the sleeve barrel of the machine tool are disassembled; a cast iron rod is fixed to a clamp seat which can make reciprocating and rotary movement; chrome oxide is sprayed on the cast iron rod by a spray coating machine; a cast iron grinding rod makes reciprocating movement and rotary movement in the sleeve barrel horizontally and simultaneously to grind a plastic sleeve in the sleeve barrel until that the size of the plastic sleeve is matched with that of the sleeve barrel. The maintenance method of the present invention is simple and practical, obviously reduces the maintenance cost of the expensive machine tool, and prolongs the service life of the machine tool.
Description
Technical field
The present invention relates to a kind of method for maintaining of plant equipment, particularly a kind of method of keeping in repair dedicated digit controlled machine tool plastic jacket.
Technical background
Lathe such as lathe, milling machine, grinding machine, planer etc. are field of machining plant equipment commonly used, are used for processing various plant equipment.Lathe is the important process equipment with the system axle shape product of sending a car.At present, along with development of numerical control (NC) technology, lathe has developed into the Digit Control Machine Tool that adopts computer or microcomputer control procedure and machining accuracy.But Digit Control Machine Tool costs an arm and a leg, and a for example Americanized name is called Cincinnati TC200 type series lathe, and its tailstock studs with plastic sheath, and sleeve is a steel part, promotes sleeve by hydraulic means and moves back and forth in plastic sheath.Time one is long, because the influence of temperature and humidity, plastic sheath expands, and tailstock and sleeve gap dwindle, and make under the normal oil pressure, and sleeve can not move back and forth in tailstock, influences the range of work.The tailstock and the replacement cost height of sleeve of Cincinnati TC200 type series lathe, the general repair method that adopts edge tin zinc-copper cover, not only the repair cycle long, need spend tens0000 yuan.And there are two aspect defectives in this repairing mode, and the first has changed the former project organization of lathe, and its two tin zinc-copper overlaps and do not have elasticity of plastics good, influences part processing precision.
Summary of the invention
The present invention is directed to expensive Repairing of Numerically Controlled Machine Tool or replacing tailstock and sleeve program complexity in the prior art, expensive shortcoming provides a kind of method of keeping in repair the specialized nc machine tool sleeve simple and efficient, that quality is controlled easily, expense is cheap.The concrete grammar of maintenance is as follows:
1. determine the actual size of tailstock and sleeve;
2. determine the size of grinding rod according to the actual size of tailstock and sleeve;
3. use cast iron to make grinding rod;
4. grinding rod is fixed on the rotation chuck;
5. smearing material on grinding rod is chromium oxide grinding grease;
6. the moving grinding rod of rotating clamp dribbling is made rotation and horizontal reciprocating movement in plastic sheath, grinds plastic sheath repeatedly, has expanded the plastic sheath gap, till the suitable dimension internal diameter;
7. extraction grinding rod;
8. sleeve is installed in the tailstock.
The advantage of the process of repairing sleeve of the present invention is:
1. make cylinder iron as the grinding rod material, hardness is moderate, and is lower, durable than copper, steel grinding rod cost, long service life.
Maintenance time short, only need 8 hours usually, save enterprise's lathe rehabilitation cost.It should be noted that making is the applicant's initiative as grinding rod grinding plastic sheath cylinder iron, its result of use is remarkable.
Specific embodiment
Below the embodiment of the invention is further described, but not as a limitation of the invention.
The method step of the method for the invention maintenance special purpose machine tool tailstock and sleeve is:
(1) dismounting tailstock tool and sleeve;
(2) use measuring instrument to measure the internal diameter of described sleeve, determine to need to expand the concrete size of sleeve diameter;
(3) prepare the cast iron grinding rod according to the size of need expansion sleeve diameter;
(4) cast iron bar is fixed on the deck that to do back and forth and rotatablely move;
(5) use spray coating mechanical on cast iron bar, to spray chromium oxide;
(6) starting deck makes the cast iron grinding rod make horizontal reciprocating movement simultaneously and rotatablely move in plastic sheath;
(7) internal diameter of plastic sheath is extended to the size of defined;
(8) grinding rod is shifted out sleeve;
(9) plastic sheath is arranged in the tailstock, and sleeve is installed in the plastic sheath;
(10) tailstock tool and sleeve are combined
Specific embodiment of the present invention has been done detailed explanation to the content of invention.For the general engineering technology personnel of this area, without departing from the premise in the spirit of the present invention, any conspicuous change to it is done all constitutes infringement of patent right of the present invention, and with corresponding legal responsibilities.
Claims (2)
1. method of keeping in repair the specialized nc machine tool sleeve, the step of this method is:
(1) determines the actual size of tailstock and sleeve;
(2) determine the size of cast iron grinding rod according to the actual size of tailstock and sleeve;
(3) make the cast iron grinding rod according to required size;
(4) grinding rod is fixed on the chuck;
(5) on grinding rod, smear abrasive pastes;
(6) start chuck, make it drive grinding rod and in plastic sheath, make rotation and horizontal reciprocating movement, to expand the plastic sheath gap, till the suitable dimension internal diameter;
(7) extract grinding rod out;
(8) plastic sheath is arranged in the tailstock, and sleeve is installed in the plastic sheath.
2. a kind of method of keeping in repair the specialized nc machine tool sleeve according to claim 1, the material that it is characterized in that abrasive pastes is a chromium oxide.
