Abstract
An automatic butt connection mechanism for capstan and low-temp fluid delivering unit features that an insulating elastic sleeve tube is used between the cooling medium supplying system and the one of the fluid inlets on polygonal capstan. When said polygonal capstan ais turned by an angle, said elastic sleeve tube can be automatically withdrawn and then connected with another fluid inlet in working state.
Description
Technical field:
The present invention relates to a kind of cutterhead self-closing cryogen conveying device, relevant with the metal cutting process technology, be mainly used in the sub-cooled of lathe grinding point, reach work cutter spacing to indexable polygonal cutterhead, the purpose of low-temperature cooling media is provided.
Background technology:
Existing lathe, especially numerically controlled lathe adopt indexable polygonal cutterhead more, and 6～8 cutter installation sites are generally arranged.During machining,, often need cooling agent is injected cutting region in order to cool off cutter; Generally be by external pipe, directly the mode of spray is finished this work.Along with development of technology, by cutter with holes, to spray the mode of the cooling of finish from inside to outside and grow up, this mode is called as interior cold working.So, the anchor clamps that cold drill bit, interior cold milling cutter, interior cold lathe tool and interior cold working are used in having occurred etc.
The later stage nineties, pollute in order to reduce finish, bring into use the DRY CUTTING mode abroad, this mode is cut with very high speed (speed of mainshaft 2～60,000 rev/min), high strength cutter, very little cutting depth, allow processing heat be taken away by smear metal more than 95%, realize no oiling processing.But this mode is with high content of technology, the equipment one-time investment big, the cutter price is expensive.
Recent years, the processing mode of the another kind of no oiling of appearance that is: replaces finish with gas again, processing stand is implemented the mode of cooling.Cost is much lower, cold working in also being fit to certainly.
The end of the nineties, inventors etc. have tried out compressed-air actuated temperature have been reduced to--20 ℃～--30 ℃, and the cold air shower nozzle placed from the position of cutting point 20 millimeter, spray the machining mode of cutter blade tip, respond well.But we found among the De Shi Practice in several years: pipeline colod-application in arranging on lathe is relatively more difficult, has to use the mode of external cooling to be processed; Especially with the indexable polygonal cutterhead of numerically controlled lathe the time, use cryogenic gas to spray cutting, often interfering because of shower nozzle or pipeline influence operation, and cooling effect is also not ideal enough, and there are the following problems again to use interior cold working instead:
● owing to be not incubated measure, temperature loss was very serious when cryogenic gas passed through cutter platform, cutterhead, tool rest to cutter;
● in order to reduce temperature loss, use the mode that near cold air duct shower nozzle direct and that cutter is connects firmly instead, the insulation problem can solve preferably; But processing must be unloaded cool air hose again during tool changing, wait polygonal cutterhead transposition to finish after, again from new insertion, very inconvenient.
Summary of the invention:
The objective of the invention is to: overcome above-mentioned weak point of the prior art, and provide a kind of coolant temperature loss little, polygonal cutterhead can free transposition, and do not interfere with cooling medium supply system (or cool air hose---down with), can automatic capturing, the cutterhead self-closing cryogen conveying device of connection.
Feature of the present invention is: adopt and on lathe cutter platform the transition Connection Block is set, be provided with the hollow elasticity cover of insulation measure on the transition Connection Block; One end of hollow elasticity cover communicates with the cooling medium supply system that the insulation measure is arranged, the other end is under elastic reaction, be close to the arrival end that polygonal cutterhead enters that fluid passage of duty, and near the cooling medium supply system cooling medium shower nozzle with being arranged on cutter of insulation measure connected; During the cutter transposition, hollow elasticity cover contracts after automatically, and after transposition finished, the hollow elasticity cover was close to the arrival end that cutterhead enters that fluid passage of duty again automatically, the structure of connecting with near the cooling medium shower nozzle the cutter that puts in place.In addition, described insulation measure will comprise: the structure that adopts measures such as vacuum heat-preserving, the high thermal resistance heat-insulating material making of use or parcel.
Description of drawings:
Accompanying drawing one, be the structure chart of transposition cutterhead self-closing insulation passage, wherein:
The polygonal cutterhead of 1----; The 2----arrival end; 3----transition Connection Block; 4----cutter platform;
5----hollow elasticity cover; 6----cooling medium supply system; The 7----spring.
Among the figure, lathe cutter platform 4 is provided with transition Connection Block 3, is provided with the hollow elasticity cover of handling through insulation 5 on transition Connection Block 3; One end of hollow elasticity cover 5 communicates with the cooling medium supply system 6 that the insulation measure is arranged, and hollow elasticity cover 5 is close to the arrival end 2 of that fluid passage that enters duty on the cutterhead 1 under the compressing of contained spring 7; During the cutterhead transposition, hollow elasticity cover 5 contracts after automatically, after transposition finishes, connect with arrival end 2 automatically again from that fluid passage of newly entering duty, low-temperature cooling media be transported to Tool in Cutting point near.
The specific embodiment:
Figure one, be a kind of embodiment of cutterhead self-closing cryogen conveying device, can be from seeing among the figure: be provided with transition Connection Block 3 at lathe cutter platform 4, transition Connection Block 3 be provided with the hollow elasticity cover of making of insulation material 5; One end of hollow elasticity cover 5 communicates with the cooling medium supply system that the insulation measure is arranged; In its inside spring 7 is housed, makes the other end under elastic reaction, be close to the arrival end 2 that enters that fluid passage of duty on the polygonal cutterhead 1, constitute and the fluid passage that has insulation measure cooling medium supply system to communicate; During cutterhead 1 transposition, hollow elasticity cover 5 contracts after automatically, and the cone of its front end withdraws from from the taper hole on the arrival end 2, after transposition finishes, automatically insert taper hole again and connect, cooling medium (gas or liquid) is transported near the cutting point with arrival end 2 from that fluid passage of newly entering duty.In order to prevent unnecessary leakage, also be provided with sealing part on the next door of cone.
Claims (2)
1, cutterhead self-closing cryogen conveying device is characterized in that: adopt and on lathe cutter platform the transition Connection Block is set, be provided with the hollow elasticity cover of insulation measure on the transition Connection Block; One end of hollow elasticity cover communicates with the cooling medium supply system that the insulation measure is arranged, the other end is under elastic reaction, be close to the arrival end that polygonal cutterhead enters that fluid passage of duty, and near the cooling medium supply system cooling medium shower nozzle with being arranged on cutter of insulation measure connected; During polygonal cutterhead transposition, the hollow elasticity cover contracts after automatically; After transposition finished, the hollow elasticity cover was close to the arrival end that polygonal cutterhead enters that fluid passage of duty again automatically, the structure of connecting with near the cooling medium shower nozzle the cutter that puts in place.
