In the said equipment,, will further improve by the availability that satisfies the described equipment of following necessary condition when suitable assembling with when turning round required mechanism.
(1) suitably arranges each unit.
If the arrangement of each unit is inappropriate, for example, loss may take place from driver element in driving force to another unit transmission course, perhaps, if the problem that driving direction drifts about may appear in driven in translation.In addition, with regard to described sensor unit,, can not accurately measure the operating condition of another unit if sensing location is inappropriate, thereby, the timing of signal is also become inappropriate.
(2) settle each mechanical composition unit securely.
Receive at driver element with from described driver element driving force with the unit of carrying out scheduled operation, can produce a kind of stress, this pressure makes whole unit under the reaction force acts of described driving force, moves along the reverse direction of driving direction.In other words, when each unit not by firm fixedly the time, the position of each unit can change along with the reacting force of described driving force, because the driving body such as cam turns round repeatedly, wherein rotation axis is eccentric and the defective that causes turning round, entire mechanism can be in the state (clattering state) that a kind of so-called click clatter that is caused by vibration etc. is made a sound, so that entire mechanism finally can't turn round.
(3) be easy to change the arrangement position of each unit.
For example, be placed upside down under the situation of scheduled unit in front and back or according to the situation when a unit and another elements exchange, perhaps under the situation of the arrangement position of fine-adjusting unit several times, be necessary to make the unit to be easy to adhere to and separate with respect to attachment such as rail 10X.Here, adhere to easily with separating and be meant that simple to operate, this operation of adhering to separating do not need speciality tool, and needn't use very big power.In brief, this is meant and adheres to/separate and mobile unit can be finished at short notice, does not need special expertise, instrument and very big power in the operation.
This point is conflicted mutually with above-mentioned requirement (2).Contradictory relation may cause usually like this: when firm fixed cell, adhere to the convenience of separating and can reduce; When raising is adhered to the convenience of separating, can sacrifice fixing firm degree again.Yet,, on its availability, will step major step as equipment if these two attributes can coexist each other.
Consider the above-mentioned prior art in the above-mentioned viewpoint, from forming nearly all this angle of needed mechanical hook-up, it almost is perfect as equipment.But because each mechanical hook-up is fixed to predetermined rail 10X by bolt B shown in Figure 12, B can easily satisfy about firmly fixing each unit in the condition (2) by tighting a bolt.Yet, need be such as the instrument of turnscrew and adjustable wrench with set bolt, and the fine setting of at every turn carrying out the position all needs to repeat to unclamp and the operation of the B that tights a bolt.Therefore, being difficult to should be easy in the realization (3) finely tunes the arrangement of unit.In addition, the described bolt clear opening of each unit is to be used for fine setting at the elliptical aperture that the Y direction is extended, and does not also claim it is to finely tune expediently far away in the mode of carrying out the fine setting on the Y direction.
Summary of the invention

Embodiment
[first embodiment]
To be described in detail one embodiment of the present of invention with reference to the accompanying drawings.
Fig. 1 to Fig. 4 illustrates the structure according to the anchor clamps of the unit of first embodiment of the invention.
Fig. 1 and Fig. 2 are the diagrammatic sketch of structure that the separable mechanism of anchor clamps is shown substantially, and according to first embodiment, this separable mechanism will be contained in the described anchor clamps.
Separable mechanism uses permanent magnet, as will be described later, control the described permanent magnet magnetic line of force the infiltration situation so that the base material of described mechanism and absorption target adsorb or separate.Described separable mechanism is made up of 2 pieces 30 and 31 that show among the figure, and piece 30 and 31 all is to construct like this, makes them to rotate relatively around its axle center.In the following description, spill spin block 3 situations are given an example and explained.In schematic structure, piece 30 and 31 all is processed into cylindrical shape.
At first, the structure of description block 30.Reference number 32 is to be processed into tabular permanent magnet, and it is constructed to have the magnet of the brute force of this degree: whole anchor clamps can be adsorbed securely and be fixed on the described base material.The piece of being made by the magnetic permeability material forms body 33a and 33b places and is fixed on the permanent magnet 32, makes permanent magnet 32 is clipped in therebetween, thereby intactly construct cylindrical first 30 on whole.Permanent magnet 32 is placed on piece 30 the insides, makes each magnetic pole be positioned on two cylindrical first 30 end surfaces.
Then, form body 34a, 34b by piece for second 31 and form the dividing plate 35 that body 34a and 34b clip by these pieces and form with the magnetic permeability that is similar to first 30.Be configured to for second 31 cylindrical, from the appearance, its have with first 30 basic identical.Yet different with permanent magnet 32, dividing plate 35 is nonmagnetic substances.Therefore, described dividing plate will be called as non magnetic dividing plate.
Above-mentioned first 30 end surfaces and second 31 a end surfaces is placed in intimate contact mutually in making the piece 30 can be around the state of its axle center rotation.Like this, shown in Figure 1A, when the end surfaces that the end surfaces of forming body 33a and 33b when each piece of first and each piece of second are formed body 34a and 34b was in mutually closely state of contact on the whole, these pieces composition bodies separately became one to constitute a magnetic permeability path.Therefore, the magnetic line of force of permanent magnet 32 sees through the base material 36 as fixed object, as shown in Figure 2.In other words, when each piece 30,31 was in state shown in Figure 1A, the separable mechanism that is made up of piece 30,31 was by the firm base material 36 that is adsorbed onto.
Simultaneously, shown in Figure 1B, revolve when turning 90 degrees when first 30 that is in Figure 1A state, the combination that piece is formed main body in the piece 30,31 is cancelled.Therefore, the magnetic line of force of permanent magnet 32 only penetrates first piece composition body 33a, 33b and second piece is formed body 34a, 34b, does not arrive second 31 bottom as absorption surface.So, can not go up the absorption affinity of base material 36 and to produce at the absorption surface (second one end surfaces as illustrated in Figure 1) of the separable mechanism of second end surfaces.In other words, only allow first 30 and second 31 around its axle center and revolve turn 90 degrees, just can control the penetrating of the magnetic line of force of permanent magnet 32, thereby very easily will be attached on the described base material and separate with it in conjunction with the clamp body of separable mechanism.In addition, though can be difficult to realize making second 31 rotation that firmly is adsorbed onto on the base material 36 at the first 30 relative magnetic line of force of controlling permanent magnet 32 when turning 90 degrees that revolves with second 31.Therefore, by rotate control for first 30 second magnetic line of force on the absorption surface be reality feasible.
Fig. 3 and Fig. 4 diagram are in conjunction with the anchor clamps of adsorbing mechanism illustrated in figures 1 and 2.
In rotating cylinder 37 inside, place and fixed to have and formed body 33a, 33b with the permanent magnet 32 of similar platy structure illustrated in figures 1 and 2 and piece, make piece form body 33a, 33b permanent magnet 32 is clipped in the middle.In other words, illustrated in figures 1 and 2 is fixed in the rotating cylinder 37, and first 30 is constructed to rotating cylinder 37 rotations.
By formed by piece that body 34a, 34b be clipped in that therebetween non magnetic dividing plate 35 forms per two 31 processed, place and be fixed in this tube.Although pin 42 protrudes as the handle that is used to rotate rotating cylinder 37 from rotating cylinder 37 tops in Fig. 3, these pins omit in Fig. 4.
Consider said structure, first 30 permanent magnet 32 is vertical mutually with second 31 non magnetic dividing plate 35 among Fig. 4 A, and as shown in the figure, in stationary magazine creel 38, first piece composition body 33a, 33b and second piece are formed body 34a, 34b and are not combined.Therefore, the bottom of the magnetic line of force no show fixed block 31 of permanent magnet 32, therefore, described anchor clamps are not adsorbed to base material 36, but are in the state that can move freely.
In Fig. 3, the pedestal of reference number 41 outgoing mechanism component units, and each mechanism stable is fixed to pedestal 41.The 41 notch 41a that are formed for installing each anchor clamps 40 on the pedestal of each unit.When the pedestal 41 of this mechanism component units was placed on the precalculated position of base material 36, the stationary magazine creel 38 of anchor clamps 40 was positioned this notch place.Under this state, the slip-proofing device 39 that the pressing section 38A that give prominence to from stationary magazine creel 38 peripheries provide and the surface adjacency of pedestal 41.
When pedestal 41 is positioned over position suitable on the base material 36, the rotating cylinder 37 that is placed on the anchor clamps 40 on the notch 41a revolved to locking direction turn 90 degrees.Like this, shown in Fig. 4 B, the piece that first 30 piece is formed body 33a, 33b and second 31 is formed main body 34a, 34b and is combined, and the magnetic force of permanent magnet 32 penetrates base material 36, and anchor clamps 40 just are adsorbed onto pedestal 36 securely like this.In the case, because the bottom part and the gap W1 between the base material 36 of the slip-proofing device 39 of anchor clamps 40 are set to the value littler than the thickness of pedestal 41, anchor clamps 40 are adsorbed onto on the base material 36 securely, make slip-proofing device 39 distortion and compacted to eliminate this difference to be pressed against on the pedestal 41, shown in Fig. 4 B.More specifically, anchor clamps 40 self firmly and securely are fixed to base material 36, and pedestal 41 is firmly fixed at the precalculated position by anchor clamps 40 by slip-proofing device 39.If carry out fine setting to pedestal 41 positions, turn 90 degrees once to the release sidespin by making rotating cylinder 37, can discharge this stationary state fully.Therefore, at this in the case, the placement location of pedestal 41 obtains fine setting, and after fine setting is finished, rotates rotating cylinder 37 once more to the locking side, to firmly fix this pedestal.
In structure shown in Figure 3, pin 43 is outstanding from anchor clamps 40, and pin 43 inserts and location pin through hole 41b wherein forms on pedestal 41.When settling anchor clamps 40, pin 43 is inserted among the pin through hole 41b, is easy to carry out the operation to anchor clamps 40 like this.
Because stationary magazine creel 38 sides firmly and stably are fixed on the base material 36 with pedestal 41 by anchor clamps 40, rotating cylinder 37 can easily be rotated to unlocking condition on top.But, be placed in described notch and rotating cylinder 37 is rotated from released state with under the situation of lock-out state at anchor clamps 40, when beginning the rotation of rotating cylinder 37, stationary magazine creel 38 is not adsorbed onto on the base material 36, this may cause that stationary magazine creel 38 and turnbarrel 37 rotate synchronously, perhaps may change the position of whole anchor clamps 40.Therefore, what the user must consider is with a hand stationary magazine creel 38 to be firmly fixed, and rotating cylinder 37 is rotated carefully in this state.In this example, when pin 43 is meshed with pin through hole 41b,, all use a hand-screw to change turnbarrel 37, make anchor clamps 40 easily to be adsorbed and to separate no matter be in the lock state still released state.
[second embodiment]
Fig. 5 and Fig. 6 illustrate according to the anchor clamps in the second embodiment of the invention 43.
Fig. 5 illustrates the composition situation of the separable mechanism that will be contained in the anchor clamps 43, and wherein, reference number 44a, 44b refer to form body with the piece of magnetic permeability material, and reference number 45a, 45b refer to be formed the non magnetic dividing plate that body 44a, 44b are clipped in the middle by piece.Reference number 46 finger-types become the columniform permanent magnet of axle center on the direction vertical with figure.Each magnetic pole is in the radially formation of this cylindrical shape, and permanent magnet 46 can rotate around the axle center in this piece.
In the state of Fig. 5, the magnetic pole of permanent magnet 46 is positioned and places to form main 44a, 44b in the face of piece separately, and like this, the magnetic line of force of permanent magnet 46 penetrates into piece by base material 36 and forms body 44a, 44b.In other words, when the magnetic pole of the location permanent magnet 46 of level as shown in the figure, this separable mechanism is adsorbed securely and is fixed on the base material 36.In addition, when by with permanent magnet 46 from then on state revolve and turn 90 degrees, when each magnetic pole was located in non magnetic bulkhead sides, the described magnetic line of force was not formed body 44a, the 44b from piece and is penetrated out, thereby makes separable mechanism lose absorption affinity.
The anchor clamps 43 of Fig. 6 A and Fig. 6 B illustrate the anchor clamps based on the said structure structure.Reference number 47 expression is used to make the lever of permanent magnet 46 rotations of a part that forms these anchor clamps 43.By operating lever 47, the magnetic pole of permanent magnet 46 is changed 90 degree, so that anchor clamps 43 are adsorbed to base material 36 or from its separation, as shown in Figure 5.
The tight part of reference number 43A finger pressure, its sidewall sections from the jig main body 43 that forms rectangle basically protrudes.These pressing sections 43A is fixedly secured to jig main body 43, makes to carry out the adjustment of position on the vertical direction by bolt 43Aa.Slip-proofing device 39 protrudes to the direction of fixed target from pressing section 43A, is similar to anchor clamps 40.
Here, the function of slip-proofing device 39 (characteristic) is described in detail below with reference to Fig. 7.The structure of the schematically illustrated described anchor clamps of Fig. 7.
In other words, suppose that the absorption affinity F1 that is produced by the magnetic force of anchor clamps 43 is 15kg.If distance W 1 is 10mm for the width W 2 of the pedestal 41 of 9mm and unit between slip-proofing device 39 and the base material 36 when not adsorbing, for fixed target pedestal 41, the reacting force F2=7.5kg and the pressure F3=7.5kg that establish pressure under ideal conditions are appropriate.
More specifically, in said circumstances, the elasticity coefficient K=7.5kg/Lmm of slip-proofing device 39.Under this state, if the thickness W2 of fixed target pedestal 41 has ± deviation of 0.1mm, the reacting force F2=7.5kg ± 0.75kg of pressure, similarly, pressure F3 also becomes 7.5kg ± 0.75kg (seeing Fig. 7 B).
Therefore, under any circumstance, anchor clamps 43 or fixed target pedestal 41 all may drift to 6.75kg.But in many cases, this enough is used for fixing the unit of common teaching.More than be description, form when main, one or more anchor clamps are used for each unit, make it possible to easily obtain required bed knife when forming the unit to the absorption affinity of anchor clamps.
[the 3rd embodiment]
Fig. 8 illustrates the anchor clamps according to the 3rd embodiment.
The magnetic line of force of control magnet makes anchor clamps adhere to or separate with base material 36 among above-mentioned arbitrary embodiment.In the above-mentioned arbitrary embodiment and the 4th embodiment that will here describe after a while,, by force anchor clamps are separated with base material 36 by the strength opposite with the absorption affinity of magnet.
Permanent magnet (Horseshoe magnet in illustrative example) 60 is contained in the anchor clamps 43, and anchor clamps 43 are adsorbed onto on the base material 36 by permanent magnet 60.Reference number 61 is represented lever, and it is configured to rotate around its axis of rotation L.In addition, the distance setting from the bottom 61a of lever 61 to axis of rotation L is than 36 the longer value of distance from axis of rotation L to base material.Therefore, when the magnetic force of anchor clamps 43 by permanent magnet 60 was adsorbed onto on the base material 36, the angle that lever 61 is positioned to tilt was shown in Fig. 8 A.
In this case, lever 61 rotates to directions X, because the length setting of rotation wall must be than 36 the distance from axis of rotation L to base material in the lever 61, rotation by lever 61 bottoms, whole anchor clamps 43 are risen against the magnetic force direction of permanent magnet 60, make the stationary state of pedestal 41 be released.Thus, owing to be inversely proportional to, only, the absorption affinity of whole anchor clamps 43 is significantly reduced by anchor clamps 43 and base material 36 are separated a little by the absorption affinity of magnetic force generation and the quadratic power of distance.For example, when identical when being made as 15kg in the absorption affinity F1 of permanent magnet 60 and the last example, whole anchor clamps 43 are separated about distance of 1 to 2mm from base material 36, anchor clamps 43 just can easily be removed from base material 36.
[the 4th embodiment]
It is the improved embodiment of the 3rd embodiment that present embodiment can be described as.
More specifically, in the 4th embodiment, being used for the device that anchor clamps 43 separate from base material 36 is not lever 61, but directly forms at pressing section 43A.Perhaps, rotation and the screw rod (male thread) of box thread part 62 by being threaded, described box thread part 62 (structure as shown in the figure) is outstanding from pressing section 43A, makes anchor clamps 36 or to break away from (state shown in Fig. 9 B) by firm fixing (state shown in Fig. 9 A).
Figure 10 A and Figure 10 B are depicted as the situation of the anchor clamps 43 of use second embodiment with the component units coupling of a plurality of mechanisms.
In the drawings, reference character U 1 refers to the driver unit, and it provides driving force to another unit.The drive motor M that is used to produce described driving force is fixed on pedestal 41A, and coupling unit 50A is installed on the drive motor M, forms the part of coupling mechanism 50.
Reference character U 2 refers to machine assembly, and its driving force that is configured to utilize driver unit U1 to be provided is carried out scheduled operation.Schematic structure comprises coupling unit 50B, is used for and the screw rod 48 of link 50B coupling and the slide block 49 that is threaded with screw rod 48.
Installation to these unit then will be described.At first, driver unit U1 is placed in the precalculated position on the base material 36.When described installation position is suitable,, make and under this state, lever 47 is rotated along directions X the ora terminalis part that pressing section 43b is positioned the pedestal 41A of driver unit U1 with first anchor clamps 43 (hereinafter referring to) of release (lever 47 places the state of Y side among Fig. 6 A) with reference number 43-1.Like this, the absorption that anchor clamps 43-1 is firm also is fixed to base material 36 sides, is fixed to base material 36 with the pedestal 41A with driver unit U1.Owing to have only independent anchor clamps 43-1, the position of driver unit U1 self might be changed by the reacting force of drive motor M rotating force, in the case, next anchor clamps 43-2 is placed in the another location of pedestal 41A, with more firm fixed pedestal 41A.In this operation, if necessary the position of driver unit U1 is finely tuned, can carry out the locking and unlocking to described anchor clamps by the lever of operating each anchor clamps, thereby very easily finely tune, this situation with embodiment above is similar.
After finishing the installation of driver unit U1, U2 is placed in correct position with machine assembly, makes the correct coupling of coupling unit 50A of coupling unit 50B and the driver unit U1 of machine assembly U2.In the case, by with driver unit U1 fixation case similar operation, the pedestal 41B of machine assembly U2 is fixed on the base material 36 by anchor clamps 43-3.In addition, U1 is similar with the driver unit, when being necessary to fix more firmly, can fix by using next anchor clamps 43-4 etc. as required.
