Specific embodiment
With reference to the accompanying drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
It describes in detail bright.
A kind of displacement platform stroke range regulating mechanism, displacement platform includes the sliding rail 11 and sliding block 20 for constituting sliding cooperation, sliding
Position switch 30a, 30b are set on the pedestal 10 of 11 side of rail, and sliding block 20 is equipped with spacing stepless continuous adjustable first, second
Touching lever 21a, 21b can be suitable for high-precision measurement and test site to meet the required precision that sliding block 20 is displaced distance
Scape, first, second touching lever 21a, 21b are located between contact 31a, 31b of the first and second position switch and constitute touching formula with it and match
It closes.
It should be noted that touching formula cooperation mentioned here, not only includes that touching lever is directly contacted with two components of contact,
It further include that touching lever enters in the sphere of action of contact, it is logical without the related circuit realized in the case where practical contact in two components
Disconnected control.For example, metal touching lever, which enters in the magnetic field, makes oscillation electricity when contact is the coil magnetic field of frequency stabilization concussion
Road variation, and then generate control signal.That is, the first touching lever 21a and first position switch 30a, the second touching lever 21b and the
Two position switch 30b composition has contact or contactless position switch.
As shown in Figure 3,4, when first, second touching lever 21a, 21b is in position shown in Fig. 3, the stroke range of sliding block 20
For L3+L4；When first, second touching lever 21a, 21b is in position shown in Fig. 4, the stroke range of sliding block 20 is L3 '+L4 '.
When in use, first, second touching lever 21a, 21b between spaced apart two position switch 30a, 30b
As sliding block 20 is subjected to displacement under the driving of power source and the guiding of sliding rail 11.When sliding block 20 is to first position switch 30a institute
When side is moved to the position that the first touching lever 21a is touched with first position switch contact 31a, power source stops driving sliding block 20
It moves, rests on sliding block 20 at the touching position, then side where power source drive sliding block 20 to the second contact 31a is displaced, until
Second touching lever 21b is touched with second position switch contact 31b, and power source stops that sliding block 20 is driven to be displaced again, and backward first
Side displacement where position switch 30a.
Specifically as shown in Fig. 1,2,5,20 side of sliding block is equipped with sliding slot 22, and there is cunning in one end of first, second touching lever 21a, 21b
It moves block to be located in sliding slot 22, the other end of first, second touching lever 21a, 21b prolongs to the region between first and second contact 31a, 31b
It stretches and intersects with the line of first and second contact 31a, 31b, have position locking between first, second touching lever 21a, 21b and sliding slot 22
Unit.Position lock cell is avoided that first, second touching lever 21a, 21b and first, second position switch contact 31a, 31b is touched
When be subjected to displacement caused by sliding block 20 displacement accuracy reduction, after releasing position locking, first, second touching lever 21a, 21b
It can realize that spacing stepless continuous is adjustable under the guiding of sliding slot 22 again.
In the present embodiment, the sliding slot 22 is the closing slot that vallecular cavity bottom is big, opening is small, and screw 23 runs through first
Closing in portion after touching lever 21a or the second touching lever 21b across 22 vallecular cavity of sliding slot is threadedly engaged in its vallecular cavity bottom with nut 24, is constituted
Position lock cell between first, second touching lever 21a, 21b and sliding slot 22.
In the specific implementation, i.e., when position lock cell is locked, screw 23 is by the body of rod of first, second touching lever 21a, 21b
Being pressed on the side wall of sliding block 20 makes the two constitute the cooperation that is connected, and guarantees the reliable of the first, second position touching lever 21a, 21b
Property, preventing touching lever 21a, 21b from sliding occurring when sliding block 20 works changes the stroke range of sliding block 20.First, second touching lever
21a, 21b and 10 clearance fit of pedestal, avoid first, second touching lever 21a, 21b from interfering at work with pedestal 10, guarantee
The stability that sliding block 20 works.
Preferably, the flute length of sliding slot 22 is oriented parallel to the rail length direction of sliding rail 11, such first, second touching lever 21a,
Spacing between 21b is consistent with the shift length of sliding block 20.For quicklook know first, second touching lever 21a, 21b's
The side wall of spacing size, pedestal 10 or sliding block 20 is equipped with the scale 41 of first, second touching lever 21a, 21b spacing of measurement.
Preferably, as shown in Figure 1, pedestal 10 is equipped with blend stop 12, blend stop 12 is located at first, second contact 31a, 31b's
Side is simultaneously located at the evacuation position of first, second touching lever 21a, 21b displacement path.Guarantee the first, second touching lever 21a, 21b
The unimpeded of path is moved, to guarantee the Stability and dependability that sliding block 20 works.
