Below, the action of position adjusting mechanism 3 is described.

When changing the position of alignment pin 2, looser a bolt B1, B2, and relax the coupling force of alignment pin 2, and linkage component 31 ~ 34 can be made to rotate around point of contact P1 ~ P4 each other.

In this condition, (Fig. 1 when the direction making alignment pin 2 to the point of contact P1 realized close to bolt B 1 is moved, with reference to white arrow), because point of contact P1 is fixed on workbench WB, therefore, point of contact P3, P4 of being symmetrically located at the bolt B 2 of position across straight line Lm (linking the straight line of the point of contact P2 of the alignment pin 2 and point of contact P1 of bolt B 1) just move to direction away from each other (Fig. 1, with reference to white arrow).

On the other hand, when the direction making alignment pin 2 to the point of contact P1 away from bolt B 1 is moved (Fig. 1, with reference to black arrow), point of contact P3, P4 of bolt B 2 just move to approximating direction (Fig. 1, with reference to black arrow).

Thereby, it is possible to make the position of alignment pin 2 move to the direction away from point of contact P1, until linkage component 32 and linkage component 33 contact with each other on straight line Lm, in this condition, alignment pin 2 is configured at apart from the point of contact P1 position farthest with workbench WB.

At this, when set this moment from point of contact P1 to the spacing distance of point of contact P2 as r time, by the B1 that loosers a bolt, position adjusting mechanism 3 also can move to the circumferential direction around point of contact P1, therefore, alignment pin 2 finally can be configured at the desired position of the inner side of the circular arc of radius r.

And, after alignment pin 2 is configured at desired position, by B1, the B2 of tighting a bolt, and improve the coupling force of alignment pin 2, and linkage component 31 ~ 34 can not be rotated around point of contact P1 ~ P4 each other, the position desired by alignment pin 2 can being held on workbench WB.

As mentioned above, in the first embodiment, (1) a kind of supporting arrangement 1, be arranged at the workbench WB of mounting workpiece W, assigned position holding workpieces W on workbench WB, wherein be configured to: by connecting member (bolt B 1, B2, bolt part 23) multiple linkage component 31 ~ 34 is linked, form cyclic position governor motion 3, position adjusting mechanism 3 is placed on workbench WB, and the P1 of in the point of contact of linkage component 31 ~ 34 is supported on workbench WB, on a P2 in other points of contact except being supported on the point of contact of workbench WB, be provided with the alignment pin 2 (engaging part) engaged with workpiece W, when changing the position of alignment pin 2 of workbench WB, weaken connecting member (bolt B 1, B2, bolt part 23) coupling force, the linkage component 31 ~ 34 linked at point of contact can be rotated each other relatively, when the position of the alignment pin 2 of stationary work-table WB, improve connecting member (bolt B 1, B2, bolt part 23) coupling force, the linkage component 31 ~ 34 linked at point of contact can not be rotated each other relatively.

When forming like this, by means of only the coupling force linking linkage component 31 ~ 34 connecting member each other (bolt B 1, B2, bolt part 23), the position desired by just alignment pin 2 can being held on workbench WB.

Thus, not needing the dedicated location maintaining body (locking mechanism) arranged in addition for alignment pin being held in desired position, just the position of alignment pin 2 can be held in desired position with simple structure.In addition, owing to not needing to arrange dedicated location maintaining body in addition, therefore, it is possible to suppress the increase of the number of parts of supporting arrangement 1, the cost of manufacture of supporting arrangement 1 can be suppressed.

In addition, owing to being provided with alignment pin 2 on the position adjusting mechanism 3 being placed in workbench WB, therefore, it is possible to the position desired by being stably held on workbench WB by alignment pin 2, and the bearing strength of workpiece W can be guaranteed.

(2) what the point of contact P1 being supported on workbench WB adopted is that the bolt B 1 linking linkage component 31 and linkage component 32 at this point of contact P1 is screwed into the bolt hole WBa being arranged at workbench WB, and be supported on the structure of workbench WB, what alignment pin 2 adopted is possess the bolt part 23 linking linkage component 33 and linkage component 34 integratedly, and is provided with the structure of alignment pin 2 and bolt part 23 coaxially.

When the work on hand platform of position of alignment pin can not be changed, because the position of the datum hole Wa of the workpiece (gearbox) of each type of automatic transmission is different, so each type needs to prepare dedicated.And, in the production line of automatic transmission, because the automatic transmission of same type is concentrated multiple stage and carries on a production line, so when a type prepares a dedicated, the increasing number of the workbench that will prepare can be caused.

When forming as described above, position desired by alignment pin 2 can being configured on workbench WB by position adjusting mechanism 3, only change the position of the bolt hole WBa of workbench WB, just position adjusting mechanism 3 can be arranged at the optional position of workbench WB.

Thus, even if the position of the datum hole Wa of the workpiece (gearbox) of each type of automatic transmission is different, also the position of the position alignment datum hole Wa of alignment pin 2 suitably can be changed, therefore, it is possible to the workbench WB providing multiple type jointly to use.

Thus, compared with the existing situation preparing a workbench with a type, the quantity of the workbench that should prepare on a production line can be suppressed, the reduction of the production cost (initial cost) of production line can be realized.

And then, in the existing situation that a type prepares a workbench, need the wide space being used for the workbench that keeping does not use, but because workbench of the present invention is the workbench WB that multiple type shares, therefore, the space that can be used in custodianship platform is narrower than existing, can realize effective utilization of idle space.

In addition, when adding the type of the automatic transmission of carrying on a production line, when work on hand platform, in order to alignment pin etc. is arranged at desired position, need the bamboo product of workbench and make again, and needing the time until make production line correspond to the type added.

When of the present invention supporting arrangement 1, due to can the supporting-point of the workbench of change of location governor motion 3 simply, therefore, when alignment pin 2 can not be configured at the position as object on workbench WB in the position adjusting mechanism 3 being supported on workbench WB, by changing the bearing position of the position adjusting mechanism 3 of workbench WB, alignment pins can be configured in all positions on workbench WB.Therefore, compared with existing, can the short time and simply correspond to add type.

And then, in the existing situation that a type prepares a workbench, whenever changing the type that will produce, all need to make production line stop and carrying out the replacing of weight and workbench.When of the present invention supporting arrangement 1, even if change the type that will produce, also need hardly to change workbench WB, the dwell time of the production line come along with the change of the type that will produce can be made shorter than existing.Thus, the raising of production efficiency can be expected.

In addition, by alignment pin 2 and the connecting member linking linkage component 33,34 are integrally constituted, preparing the different alignment pin of multiple external diameter, and when changing the type of the automatic transmission of carrying on a production line, only be replaced by the alignment pin of the external diameter matched with the datum hole Wa of new workpiece W (gearbox), just suitably can keep new workpiece W.

(3) what adopt is following structure, namely, on the linkage component 34 being positioned at a side of workbench WB side in the linkage component 33,34 that the point of contact P2 arranging alignment pin 2 links, and pedestal portion 34a1 (wide width part) be provided with in a 34a side, end of its length direction than 34b side, the other end more fabric width, the point of contact P2 arranging alignment pin 2 is the 34a side, end being provided with pedestal portion 34a1.
