Abstract
One surveys thread profile gauge soon, comprise blade, sawtooth group is measured respectively by pinned connection in the two ends of described blade length direction, each measurement sawtooth group comprises multiple stacked sawtooth sample plate, and the sawtooth specification difference on sawtooth sample plate, the middle part of described blade extends to form blade arm respectively to both sides in the width direction, each blade arm is provided with chute, measure baffle plate to be stuck in chute by the slide block on it and laterally to slide along it, the length direction of described measurement baffle plate is vertical with the length direction of blade arm; Described blade arm is respectively equipped with scale.The utility model structure is simple, reasonable in design, easy to operate, compares the measuring method that normal thread rule add vernier caliper, can quick and precisely measure screw thread specification, more reasonably utilize resource.
Description
Technical field
The utility model relates to survey instrument field, is specifically related to a kind of fast survey thread profile gauge can measuring the large path of internal and external threads.
Background technology
At present, thread profile gauge function singleness, only has the function measuring ridge number and thread form angle, namely be stuck in screw thread according to screw thread swaging clamp and measure, cannot directly measure thread size footpath, for screw thread specifications and models, also need by vernier caliper measurement thread size footpath, to table look-up or additive method is reached a conclusion.At present for those skilled in the art, need thread profile gauge and vernier caliper two kinds of instruments when measuring screw thread specification, cause the waste of resource, inefficiency and also workload large.
Utility model content
For above deficiency, the fast survey thread profile gauge that the utility model provides a kind of structure simple, reasonable in design, easy to operate.
The concrete technical scheme of the utility model is: comprise blade, sawtooth group is measured respectively by pinned connection in the two ends of described blade length direction, each measurement sawtooth group comprises multiple stacked sawtooth sample plate, and the sawtooth specification difference on sawtooth sample plate, the middle part of described blade extends to form blade arm respectively to both sides in the width direction, each blade arm is provided with chute, measure baffle plate to be stuck in chute by the slide block on it and laterally to slide along it, the length direction of described measurement baffle plate is vertical with the length direction of blade arm; Described blade arm is respectively equipped with scale.
Such scheme can be improved to further:
Described sawtooth sample plate can positioning and locking when bearing pin rotates extremely consistent with blade length direction.
Described blade arm is formed by connecting side by side by two panels clamping plate, and on two panels clamping plate respectively correspondence be provided with chute; Described measurement baffle plate to be clamped between two panels clamping plate and to be coordinated with corresponding slide by the slide block that two sides is respectively equipped with; The outside surface of described two panels clamping plate is equipped with scale.
The utility model structure is simple, reasonable in design, easy to operate, compares the measuring method that normal thread rule add vernier caliper, can quick and precisely measure screw thread specification, more reasonably utilize resource.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1-2, one surveys thread profile gauge soon, the two ends of blade 1 length direction connect respectively by bearing pin 2 measures sawtooth group, each measurement sawtooth group comprises multiple stacked sawtooth sample plate 3, and the sawtooth specification difference on sawtooth sample plate 3, the middle part of blade 2 extends to form blade arm 4 respectively to both sides in the width direction, and blade arm 4 is formed by connecting side by side by two panels clamping plate, and on two panels clamping plate respectively correspondence be provided with chute 5; Measure baffle plate 6 to be clamped between two panels clamping plate and to be slidably matched with corresponding chute 5 by the slide block 7 that two sides is respectively equipped with; The length direction measuring baffle plate 6 is vertical with the length direction of blade arm 4; The outside surface of two panels clamping plate is equipped with scale 8.
The use-pattern of this instrument is see Fig. 3-4, when large path measured by this instrument with thread form angle root for benchmark, when designing, sawtooth sample plate is indicated the tooth body degree of depth, after numerical value measured by ruler, external thread is then measured numerical value and is subtracted the tooth body degree of depth and be path, i.e. L1-H1 in this way, measurement numerical value adds the tooth body degree of depth and is large footpath, i.e. L1+H1; Internal thread is then measured numerical value and is added the upper tooth body degree of depth and be large footpath, i.e. L2+H2 in this way, otherwise is path; Like this large path of internal and external threads.
The above is preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; likely to concrete size; or partial structurtes go out some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
