The plagioclase hole of deflecting plate drives two deflecting plates opposite to two respectively in this way, push pin 24 when moving along first direction
Direction movement, that is, counter motion shown in Fig. 3 down arrows.
, it should be understood that the principle of this programme is that have the tumbler in plagioclase hole by being arranged using wedge mechanism principle, will drive
Dynamic portion is converted to the direction movement vertical with first direction, the i.e. moving direction of positioning pin most along the driving campaign of first direction
It is vertical with the driving direction of driving portion eventually.In this way, driving portion does not need to be arranged with positioning pin in the same direction, to adapt to
The positioning operation to parts to be machined 100 of many occasions avoids interfering with process equipment.
By taking Figure 10-1 as an example, Figure 10-1 is principle when Fig. 3 mesoporous positioning tool positions parts to be machined 100
Figure；Figure 10-2 is schematic diagram when prior art mesoporous positioning tool positions parts to be machined 100.
Parts to be machined 100 is set there are two mounting plate 100a, and two mounting plate 100a are equipped with location hole 100b, and two

Side.As shown in Fig. 9-2, existing positioning tool needs to be arranged in the outside of a mounting plate 100a, the driving of driving portion 200 ' one
Longer positioning pin 300 ', while being inserted into the location hole 100b of two mounting plate 100a, in this way, required positioning pin 300 '
Length can be very long, and intensity is difficult to ensure, positioning is also just unreliable, moreover, operation when hole positioning tool can block welding is empty
Between, form interference.
And as shown in fig. 9-1, the hole positioning tool in this programme can be set in the side of two mounting plate 100a, and
It is located at the part of its pedestal 20 between two mounting plate 100a, the first positioning pin 31 and the second positioning pin are also at two peaces
Between loading board 100a, then two positioning pins can stretch out in opposite directions, be inserted into the location hole 100b of two mounting plate 100a respectively,
It realizes positioning, while the welding on the outside of any mounting plate 100a will not be operated and cause to interfere.Above-mentioned setting moves toward one another
Two positioning pins, be more suitable the positioning operating condition of this double mounting plate 100a or more mounting plate 100a, protrude into adjacent
The positioning to two neighboring mounting plate 100a is realized between mounting plate 100a simultaneously.For example, parts to be machined 100 can be vehicle
Subframe, two mounting plate 100a can be to be formed installation subframe bushing mounting base.
Under this application, as previously mentioned, when the pin plate 312 that plunger 311 is arranged is arranged in positioning pin, positioning pin
After the location hole 100b of insertion parts to be machined 100 is positioned, not only plunger 311 is inserted into location hole 100b and is determined
Position, pin plate 312 can also push against the wall surface of the component of setting location hole 100b, to increase the effect of positioning, such as Figure 10-1 institute
Show, the pin plate 312 of the first positioning pin 31 and the second positioning pin can be pushed against the interior sidewall surface of two mounting plate 100a respectively.
According to above-mentioned, since the telescopic direction of positioning pin and the driving direction of driving portion are different, specifically it is mutually perpendicular to, then
Adjustment is made to the positional relationship of driving portion and positioning pin, the two does not need to be arranged in the same direction, and when installation has higher
Flexibility, to avoid the interference between equipment.
It is appreciated that based on the above principles, tumbler is not limited to setting two, more tumblers can be set, still
By taking Fig. 4 as an example, multiple L shape deflecting plates can be set from top to bottom, by the same promotion pin 24 drive move, or from a left side to
The right multiple L shape deflecting plates of setting are driven movement or a tumbler also to can connect multiple fixed respectively by multiple positioning pins
Position pin, while driving multiple positioning pins to move, or a tumbler is only set and is correspondingly arranged a positioning pin, for example, only
First positioning pin 31 is set, only a position is positioned.This programme with no restrictions, can be according to the number of actual location point
Amount and characteristic distributions carry out the setting of tumbler and positioning pin.
