Specific embodiment

According to Fig. 1 to Figure 24, embodiments of the invention one, there is haulage gear 100, switching mechanism 200 and localization machine Structure 300.

Haulage gear 100 is the assembly of kit-of-parts, and this mechanism is used for supplying power to switching mechanism 200, by its band The activity of dynamic switching mechanism 200.Switching mechanism 200 is also the assembly of multiple parts, and it will be supplied to the work required for its target Dynamic process.Detent mechanism 300 is also the assembly of multiple parts, and it is the installation foundation for installing workpiece, and workpiece is to change After varied angle or orientation, fixed clamp is in detent mechanism 300.Switching mechanism 200 is detent mechanism 300 in the present embodiment Installation foundation, the integral installation of detent mechanism 300 is in switching mechanism 200.

Haulage gear 100 has the first Mobile Forms, the second Mobile Forms and resting state, haulage gear during the first Mobile Forms 100 and switching mechanism 200 separate and link, during the second Mobile Forms, haulage gear 100 and switching mechanism 200 separate and relative Activity, during resting state, haulage gear 100 and switching mechanism 200 are fitted and spacing.

First Mobile Forms, the second Mobile Forms and resting state are all to express three engagement process respectively, this three processes Middle haulage gear 100 and switching mechanism 200 have the relation of cooperating, and are respectively：

When haulage gear 100 and switching mechanism 200 are in the first Mobile Forms, belong to both corresponding components and exist It is spatially separated, but yet suffers from so that both parts of being connected between the two, be exactly haulage gear 100 Associated components drive switching mechanism 200 corresponding component；

When haulage gear 100 and switching mechanism 200 are in the second Mobile Forms, belong to both corresponding components still So be spatially separated from, but from unlike the first Mobile Forms both be relative motion relation, be both some be quiet Only and another with respect to its activity, be exactly that switching mechanism 200 is in activity for the associated components of haulage gear 100 It is in static；

When haulage gear 100 and switching mechanism 200 are in resting state, belonging to both corresponding components is laminating , also make both mutually spacing and static just because of both laminatings.

First Mobile Forms have the first active path a, and the first active path a is straight line.First Mobile Forms are haulage gears 100 motor process, the first active path a is a virtual technical term, is therefore expressed with dotted line in the accompanying drawings, it is to lead Draw the mechanicses that mechanism 100 should follow it is meant that haulage gear 100 have preset along this first active path The rule of a line activities, the first linear active path a structure is relatively easy, easily assembles and keeps in repair.

Second Mobile Forms have the second active path b, and the second active path b is straight line.First Mobile Forms also lead Draw the motor process of mechanism 100, and the second active path b is also a virtual technical term, therefore in the accompanying drawings with dotted line Expression, it be mechanicses that haulage gear 100 should be followed it is meant that haulage gear 100 have preset along this The rule of the second active path b line activities, the second linear active path b structure is relatively easy, easily assembles and keeps in repair.

First active path a or the second active path b will not be limited only to rectilinear configuration, in fact haulage gear to be realized 100 and three kinds of switching mechanism 200 cooperation forms, the structure choice of haulage gear 100 is infinite, such as with this setted structure Active path can be circular, or the first active path a is straight line, and the second active path b is then non-rectilinear, when If structure relatively can be complicated if right first active path a and the second active path b different shaping, so that body becomes big Take more spaces.

First Mobile Forms have the first active path a, and the second Mobile Forms have the second active path b, the first active path a With the second active path b reverse-fitting.Reverse-fitting herein refer to haulage gear 100 the first Mobile Forms direction of motion and The second Mobile Forms direction of motion of haulage gear 100 is contrary, rather than refers to the first active path a and the second active path b originally The shape of body is contrary, for example, be just directed to for aforesaid straight line or circular not saying forward or backwards, reversely setting to make Obtain structure to simplify and stable performance.

Second Mobile Forms, resting state, the first Mobile Forms switch successively.This means that being transitioned into first from the second Mobile Forms lives Dynamically, all can live through this engagement process of resting state, rather than ignore resting state and be directly realized by the first Mobile Forms and the second work Dynamic switch, but this be also only for the situation under normal operation for, need the state of fixing a breakdown and debugging stage, Aforementioned two states are all manual intervention mutually to change it is not necessary to can achieve through resting state, and its advantage is to bring structure Compact effect stable and reliable for performance.

Switching mechanism 200 has rotating shaft 201, and rotating shaft 201 has axial line c, and axial line c is straight line, and rotating shaft 201 is with axle center Overturn centered on line c.Be used rotating shaft 201 as be towed mechanism 100 act on and be achieved turn over function part it is easy to system Make and process.Upset can be described as turning round or rotating again.Rotating shaft 201 is more crucial part in switching mechanism 200, haulage gear One of 100 purpose is that its upset of drive.Axial line c is the centrage of rotating shaft 201, and special instruction is present invention explanation Lower case in book accompanying drawing, such as the representative such as a, b, c is all virtual technical term, is also on geometric meaning, actual product Product occur a little trickle deviation when assembling runs because of reasons such as precision, but must not believe that this deviation just can disengage it from The protection domain of invention is covered it should think that protection scope of the present invention comprises to be contained in claims of the present invention Implication.

Rotating shaft 201 has rotating shaft limiting section 203 and the servo-actuated portion of rotating shaft 204, haulage gear 100 and rotating shaft during the first Mobile Forms Limiting section 203 separates, and during the first Mobile Forms, haulage gear 100 and the servo-actuated portion of rotating shaft 204 link, haulage gear during the second Mobile Forms 100 and rotating shaft limiting section 203 separate, haulage gear 100 and the servo-actuated portion of rotating shaft 204 relative motion, resting state during the second Mobile Forms When haulage gear 100 and rotating shaft limiting section 203 fit, during resting state, haulage gear 100 and rotating shaft servo-actuated portion 204 are all static.Turn The refinement structure further of axle 201, is that rotating shaft 201 is marked off rotating shaft limiting section 203 and the different portions in the servo-actuated portion of rotating shaft 204 Position is so that spacing and servo-actuated two functions have suitable reality constructs and are achieved.When the first Mobile Forms and the second Mobile Forms Haulage gear 100 and rotating shaft limiting section 203 be all individually separated and be not in contact with, and haulage gear 100 during the first Mobile Forms Servo-actuated portion 204 links with rotating shaft, is exactly the entirety that haulage gear 100 drives the servo-actuated portion of rotating shaft 204 or even rotating shaft 201, And haulage gear 100 and the servo-actuated portion of rotating shaft 204 relative motion during the second Mobile Forms, it is exactly haulage gear 100 in independence Activity and now rotating shaft servo-actuated portion 204 is static, exactly because haulage gear 100 and rotating shaft limiting section 203 paste during resting state Splice grafting makes rotating shaft 201 overall static after touch.

Rotating shaft limiting section 203 has the spacing plane of rotating shaft 205.The increase contact area being contacted by face can bring spacing can The effect leaned on.

Rotating shaft limiting section 203 has a spacing plane 205 of two rotating shafts, during the spacing plane 205 of two rotating shafts with axial line c is The heart is symmetrical arranged.Further increase contact area with static effect when improving spacing.

Indexing for rotating shaft 201 upset needs, and the spacing plane of rotating shaft of the present invention has four, and for two to symmetrically setting Put, be applied to when rotating shaft 201 rotates 90 degree spacing respectively, the section of therefore now rotating shaft 201 is square, if applying in the same manner In the indexing occasion of other angles, when such as 60 degree, then preferably processed the spacing plane of six rotating shafts, and for three to symmetrically setting Put, now its section is hexagon, the like.

Haulage gear 100 have cylinder block 101, cylinder piston rod 102, the first traction piece 103, the second traction piece 104 with And push rod 105, cylinder block 101 and the second traction piece 104 fixing assembling, push rod 105 and cylinder piston rod 102 fixing assembling, push away Bar 105 and the first traction piece 103 fixing assembling, cylinder piston rod 102 and the assembling of cylinder block 101 relative motion, the first traction piece 103 and second traction piece 104 be respectively provided with traction limiting section 106, during the first Mobile Forms two traction limiting sections 106 divide each other From during the second Mobile Forms, two traction limiting sections 106 close up each other, and during resting state, two traction limiting sections 106 respectively and overturn Mechanism 200 fits and spacing.

It is the relation interfixing that so-called fixing assembling refers to running during operation after assembling, and this section is relatively Relative motion for specifically cylinder piston rod 102 and cylinder block 101 assembles, and the assembling of this relative motion contains two mistakes Journey：One of which is the effectiveness of cylinder piston rod 102 script, and this cylinder piston rod 102 is past in the internal cylinder barrel of cylinder block 101 Multiple move, both cylinder block 101 has been static and cylinder piston rod 102 cylinder block 101 activity relatively；Wherein another kind then be pressurization and produce The raw power of promoting comprehensively to cylinder block 101, the power of promoting comprehensively may be in initial press cylinder piston rod 102 in cylinder block 101 Just produce during activity in internal cylinder barrel it is also possible to move to the limit of the internal cylinder barrel of cylinder block 101 in cylinder piston rod 102 Position is both continued pressurization after side wall and is led to, but whether how, this power of promoting comprehensively is among the first Mobile Forms or second Necessarily lead among Mobile Forms.

During the first Mobile Forms, two traction limiting section 106 expression separated from one another is both increasings in air line distance Greatly, on the contrary two traction limiting sections 106 close up expression each other during the second Mobile Forms is both reductions in air line distance, Two traction limiting section 106 certainly can make to the spacing more reliable of switching mechanism 200 although in principle a traction spacing Portion 106 already enables spacing to switching mechanism 200.Traction limiting section 106 is simply in expression traction limiting section 106 or the second Traction piece 104 is used for contacting the position of switching mechanism 200, should be substantially the first traction piece 103 and the second traction piece 104 Separated from one another or close up each other or and switching mechanism 200 fit and spacing.

Traction limiting section 106 has rigid backing plate 107, during resting state rigid backing plate 107 and switching mechanism 200 fit and Spacing.Specifically rigid backing plate 107 is fixedly connected with traction limiting section 106, for contacting switching mechanism 200, and should Wear and shock-resistant material selected by rigid backing plate 107, to ensure its service life.

Traction limiting section 106 has resilient sleeper-bearing, and during resting state, resilient sleeper-bearing and switching mechanism 200 are fitted and spacing. Flexible material is easy to for comparing aforementioned rigid material buffer, and certain life-span is longer, but comparatively positioning precision can be because becoming Shape deviation and decline, but this deformation is quite trickle, if the deformation of larger stroke then must calculate default change Shape amount and do not affect positioning precision.

Traction limiting section 106 has the spacing plane 108 of traction.In aforesaid switching mechanism 200, there is the spacing plane of rotating shaft During 205 premise, draw spacing plane 108 and plane 205 spacing with rotating shaft formed face and contact, position-limiting action stable and reliably.

Haulage gear 100 has the first slide block 109, the second slide block 110 and line rail 111, the first traction piece 103 and first Slide block 109 fixing assembling, the second traction piece 104 and the second slide block 110 fixing assembling, the first slide block 109 and line rail 111 straight line phase To slidable fit, the second slide block 110 is with line rail 111 straight line relative to slidable fit.

First traction piece 103 and the first slide block 109 can be two individual components or an one same material Part, the second traction piece 104 and the second slide block 110 are also such in the same manner, and line rail 111 is hard-wired, then the first slide block 109 is for static line rail 111 with the relative slip of the second slide block 110, thus the first traction piece 103 and the second traction Part 104 is also that the line rail 111 of geo-stationary slides, similar to the matching relationship of train and rail.

Switching mechanism 200 has with movable sprocket 206, and haulage gear 100 has conduction chain 112 and elastic traction part 113, Conduction chain 112 and engage assembling with movable sprocket 206, conduction chain 112 and elastic traction part 113 are linked and packed, the first activity During state, in conduction chain 112, during the second Mobile Forms, elastic traction part 113 pretension acts on and leads elastic traction part 113 compensating action Draw chain 112.

What the structure of this section of record solved is principle ins and outs when haulage gear 100 and switching mechanism 200 cooperation, Haulage gear 100 is driven with conduction chain 112 and turns round with movable sprocket 206, but necessary added resilience traction piece 113, because leading Drawing chain 112 will necessarily cause it to change with respect to the distance with movable sprocket 206, change so needing and can compensating relative position Compensating part, elastic traction part 113 now plays this effect by elastic deformation, is benefit during aforesaid first Mobile Forms Repay effect, and then need to be the action preparation of next round in advance after conduction chain 112 resets, then need to keep and with movable sprocket 206 engagement, therefore elastic traction part 113 need pretension to act on conduction chain 112, make both keep expanding force.

The following is the two ways that haulage gear 100 and its conduction chain 112 match：

Wherein mode one, referring primarily to Figure 13, is that haulage gear 100 has the first towing point 114, conduction chain 112 and One towing point 114 fixing assembling.As long as so making the first towing point 114 move, just necessarily drive conduction chain 112 and servo-actuated Sprocket wheel 206 moves；

Second another way is that haulage gear 100 has driving chain sprocket 115, and conduction chain 112 and driving chain sprocket 115 are nibbled Attach together and join, driving chain sprocket 115 and the first traction piece 103 rolling assembling, conduction chain 112 and the first traction piece 103 fixing assembling, Elastic traction part 113 and the second traction piece 104 are linked and packed.In the first traction piece 103 and 104 activity of the second traction piece, lead Draw sprocket wheel 115 just to drive conduction chain 112 or even move with movable sprocket 206.

As can be seen that the difference of mode one and mode two is to drive the mode of conduction chain 112, mode one is the equal of Direct pull and mode two are the equal of that engagement drives, and thus can amplify out a lot of derived structures：Traction may not necessarily be lain in The attachment structure at chain 112 two ends, can connect the first traction piece 103 other end with one end and connect the second traction piece 104；Or two End is all connected to the first traction piece 103 or is all connected to the second traction piece 104；First towing point 114 may come from countless Plant the associated components that it is installed, such as ball, straight-bar etc., in Figure 14, this associated components is indicated with i.

This section be still aforementioned derived structure accommodation, can be found in Figure 14：Switching mechanism 200 has supporting roller 207, traction machine Structure 100 has elastic traction part 113, and during the first Mobile Forms, elastic traction part 113 and supporting roller 207 sliding friction elasticity draw Stretch, elastic traction part 113 and supporting roller 207 sliding friction elastical retraction during the second Mobile Forms.

Flexible structure described in the preceding paragraph, its essence will be that elastic traction part 113 and the sliding friction of supporting roller 207 are joined Conjunction relation, purely relies on the sliding friction of elastic traction part 113 supply to order about supporting roller 207 and turns round, but now elastic traction part The 113 three-in-one effects simultaneously undertaking driving, elastic deformation, pretension, its elastic deformation effect and pretension effect reference respectively Aforementioned.

Elastic traction part 113 adopts form of springs in the present embodiment, and two ends connect conduction chain 112 and second respectively and lead Draw part 104, this is eaily assembling mode, but can be installed in remaining position of conduction chain 112 completely, or even Can be to play annexation between the conduction chain 112 of two-phase seperation.

Referring to Figure 15, haulage gear 100 has the first towing point 114, and the first towing point 114 and axial line c have first Traction line segment d, the first traction line segment d and axial line c is vertically-mounted, and during the first Mobile Forms, the first traction line segment d increases.First leads Lead segments d are substantially the vertical lines that the first towing point 114 arrives between axial line c, because the first towing point 114 is remote in the first Mobile Forms Make its growth from rotating shaft 201.

Haulage gear 100 has the second towing point 116, and the second towing point 116 and axial line c have the second traction line segment e, Second traction line segment e and axial line c is vertically-mounted, and during the first Mobile Forms, the second traction line segment e increases.Second traction line segment e with First traction line segment d of epimere is in the same manner.

First towing point 114 and the second towing point 116 have traction line segment f, and during the first Mobile Forms, traction line segment f increases. Line between this traction line segment f i.e. this 2 points, increases because 2 points separate during the first Mobile Forms, correspondingly, if second lives Then can draw close and reduce because of 2 points when dynamic.

Switching mechanism 200 has phantom ring 208, ratchet 209, and ratchet 209 has resting state and Mobile Forms, haulage gear 100 have traction teeth 117, and during the first Mobile Forms, ratchet 209 is in resting state, ratchet 209 and traction teeth 117 during the first Mobile Forms Geo-stationary, during the second Mobile Forms, ratchet 209 is in Mobile Forms, and during the second Mobile Forms, ratchet 209 is relative with traction teeth 117 alive Dynamic.

Phantom ring 208 essence is the lasso being socketed in the outside of rotating shaft 201 and being secured to, and traction teeth 117 essence is then It is fixed on the gear ring of the inner side with movable sprocket 206, if phantom ring 208 and traction teeth 117 want that realizing linkage need to depend on ratchet 209 The unidirectional follow-up action brought, is the first Mobile Forms of haulage gear 100 during ratchet 209 resting state, now ratchet 209 because and Traction teeth 117 abuts and both are static, and therefore haulage gear 100 carries pawl 209 and phantom ring 208 He by traction teeth 117 The entirety of rotating shaft 201, on the contrary during the second Mobile Forms, ratchet 209 is no longer on aforesaid abutted position, traction teeth 117 and ratchet 209 are in relative motion cooperation：Can be that traction teeth 117 all in activity and has certain contact and association with ratchet 209, popular For be that traction teeth 117 ratchet 209 relatively skids, also or traction teeth 117 activity and ratchet 209 is static etc..

Switching mechanism 200 has elastic component 210, and ratchet 209 and phantom ring 208 relatively rotate assembling, and elastic component 210 assembles Between phantom ring 208 and ratchet 209.

When being used spring as elastic component 210, elastic component 210 is to act on ratchet 209 all the time, ratchet herein 209 and phantom ring 208 relatively rotate assembling refer to ratchet 209 and phantom ring 208 have the relation that can relatively rotate rather than Definitely it is fixedly connected, but when being the first Mobile Forms that ratchet 209 and phantom ring 208 remain geo-stationary as previously described Carve, and be so-called to relatively rotate relation in the second Mobile Forms.

When being used spring as elastic component 210, specific structure is：Phantom ring 208 is provided with holding tank 211, first gear Side 212 and the second rib 213, holding tank 211 is with phantom ring 208 avris space insertion so that ratchet 209 is from laterally fitting into Enter this this holding tank 211, positive free surrounding space insertion makes ratchet 209 outer under the action of the spring to holding tank 211 with phantom ring 208 Protrude from phantom ring 208, ratchet 209 has rotation section 214 and contact part 215, ratchet 209 rotates around it in the geometry in portion 214 Central axis, ratchet 209 links after leaning on its contact part 215 and traction teeth 117 conflict, and the first rib 212 acts on rotation-limited Portion 214 makes ratchet 209 be unlikely to deviate from holding tank 211, and the second rib 213 acts on spacing contact part 215 and makes ratchet 209 are unlikely to evagination angle of departure spends greatly.

Detent mechanism 300 has yoke plate 301, matrix 302, lock pin 303, and matrix 302 has matrix locking cylinder 304, lock Pin 303 and yoke plate 301 fixing assembling, lock pin 303 and the assembling of matrix 302 relative motion, lock pin 303 has lock pin first inclined-plane 305, matrix locking cylinder 304 has matrix piston rod 306, and matrix piston rod 306 has matrix piston rod inclined-plane 307.This section Yoke plate 301 in the detent mechanism 300 recorded, for being directly loaded up workpiece to be added, workpiece to be added is fixedly connected with yoke plate 301, Lock pin 303 is fixedly connected with yoke plate 301 again, and workpiece therefore to be added, yoke plate 301, lock pin 303 are assembled into an entirety, by base The conflict on block piston rod inclined-plane 307 and lock pin the first inclined-plane 305 agrees with the straight-line feed conversion of motion making matrix piston rod 306 The overall relative motion with respect to substrate 302 being located for lock pin 303, completes its locking positioning in substrate 302, using oblique The mode of face cooperation locks can be had action precisely and reduce the effect worn and torn.

Lock pin 303 has lock pin first through hole 308, and lock pin the first inclined-plane 305 is located among lock pin first through hole 308.This Lock pin 303 is divided into two parts by structure, and a part is used for being threaded to be threadably secured assembling with yoke plate 301, Another part then arranges lock pin first through hole 308, two sides when being located at lock pin first through hole 308 when matrix piston rod inclined-plane 307 It can be played with the position-limiting action of both sides so as to advancing or exiting more smooth.

When workpiece to be added is loaded in detent mechanism 300, it can also carry out independent of turning over respect to detent mechanism 300 The upset of rotation mechanism 200, referred to as independent overturn, be unlikely to obscure with the upset of aforementioned switching mechanism 200 that is to say, that to be added Workpiece has two kinds of upset modes, is respectively：The first when switching mechanism 200 overturns, detent mechanism 300 and workpiece to be added Overall overturn therewith, even if it is two when being that switching mechanism 200 stops upset, workpiece to be added also can be with respect to switching mechanism 200 He Detent mechanism 300 is independent to be overturn, and both can sequentially be carried out it is also possible to synchronous carried out certainly.

Enable aforementioned independent upset and comprise Manual structure and two kinds of motor-driven structure on the whole：

Manual structure therein is embodiment three, and detent mechanism 300 has positioning and locking cylinder 309, positioning and locking cylinder 309 have positioning piston rod 310, and positioning piston rod 310 has positioning piston rod inclined-plane 311.

This structure is additionally arranged second effect and operating principle is equal to the positioning and locking cylinder of matrix locking cylinder 304 309, but the direction of action of two locking cylinders is different, when any of which locking cylinder moves back cylinder, can be by workpiece to be added Unload from matrix 302 with yoke plate 301 and the overall of lock pin 303, and be loaded into another locking cylinder in variable locking direction And by its locking, but need to manually adjust the fixed angle that lock pin 303 and workpiece to be added are relative to yoke plate 301 before loading, finally Obtain making the result of locking again after workpiece adjustment angle to be added.

In aforesaid lock pin 303, two locking cylinders are all cooperation lock pin the first inclined-planes 305 naturally it is also possible to lock pin 303 improve it is simply that lock pin 303 has lock pin the second inclined-plane 312.The direction on this lock pin the second inclined-plane 312 is different from lock pin First inclined-plane 305, in order to positioning piston rod inclined-plane 311 para-position cooperation, two inclined-planes are corresponding to correspond to two locking gas respectively Cylinder, the advantage on setting lock pin the second inclined-plane 312 is need not after the entirety of unloading workpiece and yoke plate 301 and lock pin 303 again Remove to manually adjust the fixed angle that lock pin 303 and workpiece to be added are relative to yoke plate 301.

Lock pin 303 has lock pin the second through hole 313, and lock pin the second inclined-plane 312 is located among lock pin the second through hole 313.With When sample can also be located at lock pin the second through hole 313 positioning piston rod inclined-plane 311 when matrix piston rod inclined-plane 307, two sides are permissible It is played with the position-limiting action of both sides so as to advancing or exiting more smooth.

Matrix piston rod 306 has the first reference line g, and positioning piston rod 310 has the second reference line h, the first base Line of collimation g and the second reference line h is vertically-mounted.First reference line g and the second reference line h is not two irregular shapes The piston rod inclined-plane centrage of shape, and be that they install the centrage of the cylinder barrel being located it is adaptable to adjustment angle is perpendicular respectively Two processing stations occasion.

Lock pin first through hole 308 and lock pin the second through hole 313 insertion assembling.Make lock pin 303 delicate structure compact.

Lock pin the first inclined-plane 305 and lock pin the second inclined-plane 312 intersect assembling.Both Figure of description have intersecting lens j.Thing In reality, lock pin the first inclined-plane 305 and lock pin the second inclined-plane 312, lock pin first through hole 308 and lock pin the second through hole 313 are two-by-two all It is identical moulding, lock pin 303 therefore structure is compacter and outward appearance is more brief attractive in appearance.

Motor-driven structure therein is embodiment one and embodiment two, and detent mechanism 300 has positioning cylinder 313, alignment pin Axle 314 and positioning gear 315, positioning cylinder 313 has piston rod tooth bar 316, positioning gear 315 and piston rod tooth bar 316 Engagement assembling, alignment pin 314 and matrix 302 fixing assembling, alignment pin 314 and positioning gear 315 fixing assembling.Piston rod Tooth bar 316 is provided in the tooth bar of positioning cylinder 313 piston rod periphery, it can be directly on this piston rod processing and obtain, Fill after can also being and fix on the piston rod, by the linear motion of positioning cylinder 313 piston rod, drive positioning gear 315 And rotate together with the alignment pin 314 fixing with it, matrix 302, adjust the angle with respect to switching mechanism 200 and orientation.

Matrix 302 has matrix the first location division 317, and positioning cylinder 313 has piston rod location division 318.This two fixed Position portion is by inconsistent cooperation, and piston rod location division 318 essence is the face at the end end of piston rod in positioning cylinder 313, definitely Ground says be moved along a straight line by piston rod location division 318 so that by its tailpiece of the piston rod end promote matrix 302, position gear 315 with And alignment pin 314, but the matching relationship of both does not occur in the linearly operating of each positioning cylinder 313, this It is because that the main positioning of matrix 302 relies on aforesaid rack-and-pinion cooperation to complete, simply coordinate in rack-and-pinion and occur Error or because abrasion lead to rack-and-pinion that the situations such as idle running occur when, both conflict and bring auxiliary aforementioned just can occur The result of positioning.

In addition it is also provided with extra auxiliary location structure：Detent mechanism 300 has auxiliary positioning portion 319, and matrix 302 has There is matrix the second location division 320.The effect of block is played in matrix the second location division 320, but is not that both can occur every time Conflict result, but only produce when revolution is excessive, therefore it has two prevents inertia effect, and the first prevents piston rod The revolution that brings of inertia that tooth bar 316 orders about positioning gear 315 is excessive, and it two is to prevent piston rod location division 318 from ordering about matrix The revolution that the inertia of the first location division 317 brings is excessive, thus playing the effect of precise positioning.

Auxiliary positioning portion 319 has auxiliary through hole 321, alignment pin 314 and auxiliary through hole 321 activity assembling.Auxiliary is fixed Position portion 319 and auxiliary through hole 321 essence are all the different parts of a projection, and this projection can be arranged on the outer of rotating shaft 201 Wall.Positioning gear 315 is located at centre, and both sides are two auxiliary through hole 321 respectively, then is then outwards two protrusions of matrix 302 Position, to be fixedly connected with the two ends of alignment pin 314, provides and can simplify volume while required performance as far as possible.

Detent mechanism 300 has jacket casing 322, jacket casing 322 and rotating shaft 201 fixing assembling, and jacket casing 322 and rotating shaft 201 are axially Roll adjustment assembling relatively.When embodiment three selects the structure of this extra increase of jacket casing 322, aforesaid auxiliary positioning portion 319 He Auxiliary through hole 321 be located projection just can with jacket casing 322 integral structure manufacture and obtain, if but there is no jacket casing 322, then must As embodiment two, rotating shaft 201 must be set to stagewise combinative structure, otherwise because aforesaid projection exists, rotating shaft 201 assembling will Can be extremely difficult, jacket casing 322 solves this problem easily,

The axially opposing roll adjustment assembling of jacket casing 322 and rotating shaft 201 refers to that jacket casing 322 has the pin-and-hole 323 of insertion, and has Axially back and forth position point, rotating shaft 201 also has the pin-and-hole 324 of insertion, and so after dismounting pin, jacket casing 322 just can be with respect to Axially activity before and after rotating shaft that it is socketed 201, complete after before and after's roll adjustment again with pin simultaneously will both fixing assemblings, complete to adjust Whole.

Supplementary notes, the positioning and locking cylinder 309 in Manual structure or the positioning cylinder 313 in motor-driven structure are made With differing, but installation site is identical, is all mounted in the end end of rotating shaft 201.

Below in conjunction with the integration introduction being applied to sole mould 900 occasion and being operated as air operated fixture principle, sole mould 900 need its five faces are processed, but during sole mould 900 processing, cutter is unidirectional it is therefore desirable to air operated fixture completes Rotation, to process four sides, and the process of one bottom surface of upset processing, also has more senior multi-directional cutting tool to carve certainly Machine but high cost enterprise and require high-caliber operator, also or immaturity and high cost enterprise three-dimensional printing technology, therefore Carry out the scheme that sole mould 900 processing remains more reality using this air operated fixture at this stage：

Sole mould 900 is connected to yoke plate 301, the matrix piston rod of matrix locking cylinder 304 generally by being screwed 306 propulsions, lock pin 303 are locked, the lock pin 303 of this process has a little displacement towards rotating shaft 201, and cylinder block 101 is Beidirectional model, from the beginning of with air pressure capable of being increased, straight line is drawn close each other for the first traction piece 103 and the second traction piece 104, now turn Axle 201 cannot drive it jointly to turn round because traction teeth 117 is skidded with respect to ratchet 209, spacing up to the traction lasting till both sides Till plane 108 is fitted with the spacing plane of both sides rotating shaft 205 of rotating shaft 201 respectively, as so-called second Mobile Forms.

Resting state is that rotating shaft 201 is static, the process of tool sharpening sole mould 900.

The revolution of rotating shaft 201 just can start when separated from one another in the first traction piece 103 and the second traction piece 104, and first When traction piece 103 and the second traction piece 104 separate, its driving chain sprocket 115 orders about with movable sprocket 206 by conduction chain 112, this When ratchet 209 and traction teeth 117 conflict thus linking completely, drive the whole of phantom ring 208 and rotating shaft 201 with movable sprocket 206 Body turns round, and elastic traction part 113, from the spring being relatively easy to acquisition, also begins to stress stretching, plays to compensate and leads because of first Draw part 103 and the second traction piece 104 separates conduction chain 112 potential difference leading to, because needing four sides to sole mould 900 all It is processed, therefore rotating shaft 201 needs to turn round four times, the angle of revolution is 90 degree every time, certain first traction piece 103 and second Traction piece 104 farthest limits distance separated from one another is default, can just order about rotating shaft and turn 90 degrees for 201 times, reaches distal pole Range line from after now the first Mobile Forms finish, both again draw close and repeat aforesaid second Mobile Forms afterwards.

Supplementary notes, whether Manual structure or motor-driven structure, it is all double, may correspond to double Knife carries out operation simultaneously, to improve working (machining) efficiency, it can be said that detent mechanism 300 is dual, is simultaneously fitted to overturn The both sides of mechanism 200, Figure of description is only marked to one of detent mechanism 300, the duplex of embodiment two and three Position is in different angles and is intended merely to conveniently its structure is shown, and is synchronous and symmetrical during actual job.

The difference of embodiment one, two, three, is the rotating shaft 201 in detent mechanism 300 and switching mechanism 200, says Bright book accompanying drawing is mainly shown to the inside of embodiment one, but the haulage gear 100 of three embodiments is all consistent, because This can entirely by reference to the internal structure of embodiment one.
