Technical field
The utility model relates to a kind of stair-stepping clearance ruler that can be used for accurate measurement clearance value.
Background technology
For guaranteeing that part assembles smoothly and the proper motion of kinematic pair, gap is inevitable.There is positive role in suitable gap to maintaining mechanical system steady running and premium properties; But gap may cause the problems such as the undesired vibration of mechanical system, sealing are not good, life-span reduction improperly.Therefore the measurement of studying gap width has practical significance.People have invented the structure of a series of exquisitenesses and the size that mode is carried out measurement clearance value.Such as, the combination that utilizes gap clearance gauge is measurement clearance value accurately; Utilize the triangle clearance gauge size of measurement clearance value easily; The clearance meter that has now even occurred some electronic types, comprises capacitance gap instrument and laser clearance meter etc.In Chinese patent CN202582447U, disclose a kind of clearance measurement tool, it adopts the rectangular parallelepiped or the front latter linked mode of right cylinder that increase gradually to form stair-stepping clearance measurement tool, can be advantageously used in automobile production.
At present, more for clearance measurement mode, however main gap measuring apparatus and mode have following deficiency: gap clearance gauge combination operation is complicated, in the process of combination, can bring error; Triangle clearance gauge, in the process of filling in, can be introduced the power perpendicular to gap direction, and the gap width forming for soft material is measured and can be introduced error; The clearance meter cost of electronic type is higher.In CN202582447U, disclosed clearance measurement tool, because both sides are all stepped, is difficult to alignment gap, thereby can not insert in gap easily, and measuring error is larger, can not accurately measure.
Summary of the invention
For solving above-mentioned one or more technical matters, the utility model discloses a kind of clearance ruler, clearance ruler comprises: coupling arrangement (1), total range clearance ruler (2) and a plurality of minutes range clearance rulers (3), described coupling arrangement (1) by total range clearance ruler (2) with described a plurality of minutes range clearance ruler (3) link together, total range clearance ruler (2) possesses around the ability of coupling arrangement (1) rotation with minute range clearance ruler (3), the corresponding one-component journey clearance ruler (3) of each scale of total range clearance ruler (2), within each minute, range clearance ruler (3) is the further segmentation to the corresponding meter full scale of total range clearance ruler (2).
Total range clearance ruler and a minute range clearance ruler all have end face and bottom surface, and bottom surface is a plane, and end face is stairstepping, is divided into a plurality of ladder planes, and each ladder plane is parallel with bottom surface, the corresponding gap width of each ladder plane.
On total range clearance ruler and minute range clearance ruler, there is through hole or groove, by coupling arrangement, by through hole or groove, a plurality of clearance rulers are linked together.
Coupling arrangement is pin, bolt or screw.
The beneficial effects of the utility model are:
1. read easily, it is convenient to measure, and because bottom surface is plane, thereby be easy to insert in space, measure accurately.
2. described in, stepped clearance ruler has different specifications, can select according to clearance measurement accuracy requirement.
3. described in, stepped clearance ruler does not need to carry out stack combinations.
4. described in, stepped clearance ruler is stepped, compares slope or leg-of-mutton clearance ruler, in the process of measuring, can not produce the acting force perpendicular to gap, and measuring accuracy is higher.
5. described in, stepped clearance ruler does not need electronic component, and cost is lower, and easy to operate.
Accompanying drawing explanation
Accompanying drawing illustrates embodiment of the present utility model, it should be noted that, accompanying drawing only, for illustrating principle of the present utility model, does not limit its scope, and accompanying drawing is not necessarily drawn in proportion.
Fig. 1 is the overall diagram of the utility model clearance ruler:
Fig. 2 is total range clearance ruler front view and the vertical view of the utility model clearance ruler:
1, coupling arrangement; 2, total range clearance ruler; 3, divide range clearance ruler.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are described in further details.
It should be noted that, the embodiment in the utility model is only for know-why is described, and unrestricted scope of the present utility model.In the situation that not departing from the utility model spirit and scope, by reading the utility model, those skilled in the art will recognize that various modification of the present utility model and change, these modification and change are also within the application's protection domain.
As shown in Figure 1, clearance ruler consists of total range clearance ruler 2, a plurality of minutes range clearance rulers 3 and coupling arrangement 1.Total range clearance ruler 2 and a minute range clearance ruler 3 are linked together by coupling arrangement 1.Wherein coupling arrangement 1 can be the coupling arrangements such as pin, screw, bolt or line, on total range clearance ruler 2 and minute range clearance ruler 3, there is the through hole corresponding with coupling arrangement 1 or groove, thereby coupling arrangement 1 links together total range clearance ruler 2 and a minute range clearance ruler 3 with through hole or groove fit, make total range clearance ruler 2 and minute range clearance ruler 3 can rotary moveable.Certainly, also can adopt other any movable connection method to connect total range clearance ruler 2 and minute range clearance ruler 3.As shown in Figure 1, each minute range clearance ruler 3 is the further segmentations to the corresponding scale of total range clearance ruler 2.The first minute range clearance ruler 3 that is for example close to total range clearance ruler 2 is the further segmentations to 0.90 scale of total range clearance ruler 2, and second component journey clearance ruler 3 is the further segmentations to 0.80 scale of total range clearance ruler 2, etc.Thereby a minute range clearance ruler 3 has higher precision.
As shown in Figure 2, each total range clearance ruler 2 or a minute range clearance ruler 3 have end face and bottom surface.Wherein bottom surface is a plane, and end face is stairstepping, is divided into a plurality of ladder planes, and each ladder plane is parallel with bottom surface.The corresponding gap width of each ladder plane.
During use, first total range clearance ruler 2 is tucked in gap, if total range clearance ruler 2 is stuck, uses respective components journey clearance ruler 3 instead and measure, obtain more accurate gap width.
Concrete operation step is:
Step 1: use total range clearance ruler 2, be tucked in gap, until total range clearance ruler 2 blocks, read the gap width of stuck position;
Step 2: according to the reading of step 1, select corresponding minute range clearance ruler 3 (if the reading of step 1 is 0.80mm, need to select minute range clearance ruler of 0.81-0.90mm range), be tucked in gap, until clearance ruler blocks, read the gap width of stuck position, be the gap width of measurement;
Step 3: if lower to gap width accuracy requirement, only need to perform step one; Accuracy requirement is higher, need to perform step in order one and step 2.
Total range clearance ruler 2 of clearance ruler of the present utility model and minute range clearance ruler 3 one sides are stepped, and one side is plane, and integral body is flat, the corresponding gap width of each ladder, reads easily, and it is convenient to measure, and because bottom surface is plane, thereby be easy to insert in space, measure accurately.
