Further improvement of the present invention scheme is that have pin on short vertical part corresponding with holddown spring both ends and long vertical part
Hole, is respectively fixed with the first fore-set and the second top in two pin holes, holddown spring both ends respectively with the first fore-set and the second fore-set
Neighboring terminal be connected.
Further improvement of the present invention scheme is that have the first screw hole on the short vertical part between the first fore-set and displacement sensor,
There is the first rod aperture on long vertical part corresponding with the first screw hole, there is the first screw between the first rod aperture and the first screw hole, the first screw
Front end is screwed in after passing through the first rod aperture on the outside of the first rod aperture in the first screw hole, and makes the nail lid of the first screw and long vertical part outside
Between there are gaps.
Further improvement of the present invention scheme is that have the second screw hole on the short vertical part under the first fore-set, in the second screw hole
There is the second screw.There is lower pin hole on long vertical part corresponding with the second screw hole, have spacer pin in lower pin hole；Spacer pin and the second screw
Neighboring terminal stretch out in the spacing between short vertical part and long vertical part and there are gaps between the two.
Further improvement of the present invention scheme is that there is pin cap in lower limit pin one end adjacent with the second screw, described
Pin cap is protruded in the inside of long vertical part.
The reference block is pin, and one end adjacent with displacement sensor has nail to cover, the inner end of displacement sensor and the nail
Lid offsets.
The thickness of groove bottom of the lateral slot is 0.3 ~ 0.4mm
The lateral slot is arc-shaped slot, and the line between axial and short, long vertical part is perpendicular.
As can be seen from the above scheme, since the present invention contains bottom plate and controller, there are U-shaped seat, the U-shaped seat on bottom plate
Containing short vertical part and long vertical part, there is lateral slot on the inside of long vertical part root, long vertical part upper end is connected with measuring staff in parallel, short perpendicular
There is lateral aperture in portion at the upper end, there is displacement sensor in lateral aperture, and displacement sensor is connected by conducting wire with controller.Institute
Displacement sensors are rod-shaped, and longitudinal direction is perpendicular with the longitudinal direction of short vertical part, long vertical part and measuring staff.It is corresponding with displacement sensor
Long vertical part on have reference block, displacement sensor inner end offsets with reference block.During measurement, in reference block, spring and displacement sensing
Under the action of device, the spacing between long vertical part and short vertical part with measuring staff can adjust in limited range, even if tested circular hole is inclined
Difference is larger, and measuring staff can still entered in tested circular hole.Again due to having lateral slot on the inside of long vertical part root so that long vertical part is adjacent to it
Thickness between the interior outside of root only has 0.3 ~ 0.4mm.In this way so that vertical part has good elasticity.When being terminated on measuring staff
The interior bowlder of tested circular hole is touched, if the position of circular hole, there are deviation, measuring staff can generate under the resilient force of place vertical part
Deflection, the deflection pass to sensor by the present invention flexible U-shaped pedestal variation, it is achieved thereby that workpiece from
Dynamic detection.Since only measuring staff front end is stretched into measured hole when measuring, the larger auto parts in test position space are can be not only used for
On, it is also possible on the smaller auto parts in test position space, the scope of application is unrestricted.
