The inner end of any part each means initiating terminal of the part along direction a, the outer end of any part in the utility model
Each mean clearing end of the part along direction a.
Specifically scheme is：Chuck mounting seat 10 is provided with guide pin bushing 30, pilot hole is provided with chuck mounting seat 10, leads
Set chuck 20 is slidably mounted in pilot hole along direction a, and clamping part 201 is located at the outside of chuck mounting seat 10, and governor motion is adjusted
Section guide pin bushing chuck 20 moves along direction a, and the outer peripheral face of outer stomidium inwall against the clamping part 201 of pilot hole adjusts clamping part
201 pairs of bars 200 are clamped, and direction a is the moving direction of bar 200.The size that so can adapt to bar 200 is fitted
Answering property clamps regulation so that gap is small as far as possible, ensures the machining accuracy of workpiece.
Detailed scheme is that inner end and the adapter sleeve 90 of guide pin bushing chuck 20 are connected as a single entity, and governor motion includes being used to push
The sliding sleeve 40 that adapter sleeve 90 moves, sliding sleeve 40 are slidably mounted on along direction a inside the inner end of chuck mounting seat 10, sliding sleeve 40
Ring flange 50 is set with the inner end of chuck mounting seat 10, encloses to form sky between sliding sleeve 40, chuck mounting seat 10 and ring flange 50
Cavity region, boss is provided with the periphery wall of guide pin bushing 30, cavity area is separated into the A chambers 401 and B chambers mutually completely cut off by boss
Room 402, moved by the air pressure adjustment sliding sleeve 40 adjusted in A chambers 401 and B chambers 402.So sliding sleeve 40 is just as one
Cylinder piston is the same, is moved by pneumatically adjusting sliding sleeve 40, so as to promote guide pin bushing chuck 20 to move, so as to adjust folder
Hold clamping degree of the portion 201 to bar 200.More detailed scheme is that Thrust nut 60, Thrust nut 60 are provided with sliding sleeve 40
Nut bore passed through for bar 200, ejector sleeve section is provided with the outer face of Thrust nut 60, is installed in chuck mounting seat 10 limited
Position circle 70, spacing collar 70 and 10 corresponding arrangement of chuck mounting seat, the internal orifice dimension of spacing collar 70 are more than the outer tube diameter of ejector sleeve section.Even
Female connector 90 is reducing body, including outer more than pipeline section B along the direction a pipeline section A being sequentially arranged and pipeline section B, pipeline section A external diameter
Footpath, chuck mounting seat 10 are connected with spacing collar 70 by lock-screw 21, the lock between chuck mounting seat 10 and spacing collar 70
It is arranged with compression spring 22 with the nail of tight screw 21, is provided with pressing plate 80 on the pipe table top of pipeline section A and pipeline section B junctions, presses
The through hole passed through for lock-screw 21 is opened up on plate 80, compression spring 22 drives pressing plate 80 to be carried out to close to the side of ring flange 50
It is mobile.It can so prevent clamping part 201 from clamping tension to bar, ensure the demand of work pieces process.
Operation principle of the present utility model is similar to the operation principle of cylinder, when main shaft chuck 100 clamps the workpiece of bar 200
When being penetrated from the inner end of guide pin bushing 30, compressed air is at this moment poured in A chambers 401, B chambers 402 discharge gas, A chambers 401 and B
The pressure differential of chamber 402 promotes sliding sleeve 40 to be moved forward along direction a so that the end face for the Thrust nut 60 being attached thereto and connection
The end contact fitting of set 90 promotes forward, promotes guide pin bushing chuck 20 to move forward and is unclamped so that guide pin bushing chuck 20 and rod
Expect that 200 crest clearances increase, be easy to bar 200 to penetrate guide pin bushing chuck 20.It is pushed into when main shaft chuck 100 clamps the workpiece of bar 200
During the suitable Working position in the front end of guide pin bushing chuck 20, by changing the airintake direction of A chambers 401 and B chambers 402, to B chambers
Gas, the discharge gas of A chambers 401 are rushed in 402, sliding sleeve 40 is moved along the direction with direction a contraries.At the same time,
The pressure acted on pressing plate 80 reduces, and at this moment compression spring 22 unclamps resilience, promotes pressing plate 80 to promote adapter sleeve 90 to be moved back
Dynamic, guide pin bushing chuck 20 is moved rearwards contraction.At this moment guide pin bushing chuck 20 and the gap of the outer surface of bar 200 are minimized, and are carried significantly
The high machining accuracy of part.
Locking-adjustable screw 21 makes guide pin bushing chuck 20 have the power pulled back in the utility model, pre-adjusts guide pin bushing chuck
Gap between 20 and workpiece external diameter（≤0.02mm）.When one end of bar 200 is pressed from both sides by the main shaft chuck 100 that main shaft outer end connects
Tightly, and the other end is fixed in place by guide pin bushing chuck 20, front end cutter and the axial distance of guide pin bushing 30 are relative constant, composition
Rigid connection structure, guide sleeve device provided by the utility model play a part of support.Guide pin bushing 30 in the utility model is solid
Be scheduled in frame 300, chuck mounting seat 10 with outside guide pin bushing 30 be fixedly connected by several positioning screws 31, its center with
Spindle nose keeps coaxially arranged.Rotated by the high speed of rear portion main shaft, complete the machining of part, fill the performance of main shaft
Distribution is waved, and improves machining accuracy.
After often processing a part, by the Lifting Device or main axle moving in the main shaft of rear portion, bar 200 is pushed away forward
Enter, bar 200 is stretched out guide pin bushing chuck 20 to suitable distance, continue to process second part, the like.So, main shaft
Chuck 100 clamps bar 200 and moved forward by guide sleeve device, efficiently accomplishes the processing of axle class or disk-like accessory, saves dress
The time of workpiece is unloaded, greatly increases production efficiency.
The utility model compared with similar products, it is simple in construction, safe and reliable, production efficiency is high, part locating and machining essence
Spend that high, rigidity is good, consumables cost is low, the range of work is wide, the processing especially suitable for slender axles.
