Abstract
The utility model relates to a lever inner diameter meter able to eliminate gaps. An inner diameter meter is applied to measure tolerance of an inner dimension and the shape, which is achieved in the way that a movable probe is provided at one end of the main body of the inner diameter meter frame; when the movable probe moves, the lever is driven to revolve and the probe of the indicator is driven by the mandrel so that the needle of the indicator revolves. But this structure can not remove invalid stroke between the movable probe and the lever, which makes the needle not able to restore and provides a poor indicating stability. The lever inner diameter meter able to eliminate gaps in the utility model comprises a main body (2), a movable probe (1), a lever (3), a mandrel (4) and a tapered spring (5); wherein the movable probe is provided at one end of the main body (2), the tapered spring is provided on the movable probe (1); moving of the movable probe (1) enables the lever (3) to revolve; the movable probe (1) contacts with the lever (3) all along. The utility model is applied to measure tolerance of an inner dimension and a shape.
Description
Technical field: the utility model relates to a kind of lever inside meter of eliminating the gap that has.
Background technology: inside meter is measured the inside dimension and the shape error thereof of part, be that main body one end by the internal diameter dial framework is equipped with movable gauge head, when movable gauge head moves, make the lever revolution, promote the gauge head of indicating gauge by push rod, indicator gage finger is turned round finish.But the idle motion between this kind structure existence activity gauge head and lever can't be eliminated, and being reflected on the table is that pointer does not return original position, and stability of display is poor.
Summary of the invention:
The technical problems to be solved in the utility model: provide a kind of movable gauge head to contact all the time with lever, no-idle running makes pointer return zero, the lever inside meter with elimination gap that stability of display is high.
The technical scheme that addresses the above problem:
Has the lever inside meter of eliminating the gap, its composition comprises: main body, movable gauge head, lever, push rod and awl spring, one end of described main body is equipped with movable gauge head, on described movable gauge head, the awl spring is housed, moving of described movable gauge head, make the lever revolution, movable gauge head contacts with lever all the time.
The above-mentioned lever inside meter with elimination gap, an end of described movable gauge head has tapering.
Beneficial effect compared with prior art:
1. of the present utility model have the lever inside meter of eliminating the gap, owing to improved the structure of movable gauge head, increased the awl spring, and it is fixed thereon that the movable gauge head behind the remodeling helps boring spring.
2. this product utilizes the elastic force of spring owing to increased the awl spring, and movable gauge head is contacted with lever all the time, has avoided idle motion, has overcome inside meter and has not returned zero disadvantage, has improved the stability of inside meter.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is structural representations of movable gauge head.
Below in conjunction with the concrete embodiment of description of drawings:
Embodiment 1.
Has the lever inside meter of eliminating the gap, its composition comprises: main body 2, movable gauge head 1, lever 3, push rod 4 and awl spring 5, one end of described main body 2 is equipped with movable gauge head 1, awl spring 5 is housed on described movable gauge head 1, moving of described movable gauge head 1, make lever 3 revolutions, movable gauge head 1 contacts with lever 3 all the time.
Embodiment 2.
The above-mentioned lever inside meter with elimination gap, an end of described movable gauge head 1 has tapering.
Claims (2)
1. one kind has the lever inside meter of eliminating the gap, its composition comprises: main body, movable gauge head, lever, push rod and awl spring, it is characterized in that: an end of described main body is equipped with movable gauge head, on described movable gauge head, the awl spring is housed, moving of described movable gauge head, make the lever revolution, movable gauge head contacts with lever all the time.
2. the lever inside meter with elimination gap according to claim 1, it is characterized in that: an end of described movable gauge head has tapering.
