Description
Technical field
The utility model is related to a kind of bridge-type small stair external diameter stopper measuring tool.
Background technology
Generally when the external diameter seam of part is measured, due to that cannot be measured by the short micrometer that limited of step, general platform
Rank is referred to as small stair when being highly 3~10mm, is as shown in Figure 1 the part 5 with small stair 51；And the certainty of measurement of slide calliper rule
Low, duplicate measurements uniformity is poor, and measurement inconvenient operation, and the skill set requirements to measuring operating personnel are of a relatively high, typically
Surveyor cannot measure accurate data, human factor is too high, so as to influence the processing efficiency and the accuracy of manufacture of part, very
To scrapping for part is caused, great difficulty is caused to processing, improve the difficulty of processing and processing cost of part.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of bridge-type small stair external diameter stopper measuring tool, this measurer gram
Its external diameter seam that part taken when having small stair is convenient for measuring operation using micrometer or the defect of kind of calliper, improves survey
Accuracy of measurement, reduces part machining cost, it is ensured that part machining quality.
In order to solve the above technical problems, the utility model bridge-type small stair external diameter stopper measuring tool includes saddle seat, internal diameter thousand
Divide table, gauge head and lock-screw, the saddle seat bottom surface is provided with recess, and the recess front end is provided with step, rear end inwall and is provided with
Screw, the step is provided with through hole vertically, and open slot, the open slot position of the step are provided with below the step through-hole
Vertical axial is provided with locking screw holes, and the gauge head is located at the screw of the saddle seat recess rear end inwall by screw thread, described interior
The measuring staff of footpath amesdial penetrates the through hole of the step, and the lock-screw is twisted the locking screw holes in the step and fastens institute
State inside dial indicator.
Further, the flatness error≤0.003mm of the saddle seat bottom surface recess plane.
Include saddle because the utility model bridge-type small stair external diameter stopper measuring tool employs above-mentioned technical proposal, i.e. this measurer
Shape seat, inside dial indicator, gauge head and lock-screw, saddle seat bottom surface are provided with recess, and recess front end is provided with step, rear end inwall and sets
There is screw, step is provided with through hole vertically, open slot is provided with below step through-hole, the open slot position vertical axial of step sets
There are locking screw holes, gauge head is located at the screw of saddle seat recess rear end inwall by screw thread, and the measuring staff of inside dial indicator penetrates step
Through hole, lock-screw twists the locking screw holes in step and fastens inside dial indicator.This measurer overcomes part has small
Its external diameter seam is convenient for measuring operation using micrometer or the defect of kind of calliper during rank, improves certainty of measurement, reduces part
Machining cost, it is ensured that part machining quality.
Brief description of the drawings
The utility model is described in further detail with implementation method below in conjunction with the accompanying drawings：
Fig. 1 is the part schematic diagram with small stair；
Fig. 2 is the utility model bridge-type small stair external diameter stopper measuring tool structural representation.
Specific embodiment
Embodiment is as shown in Fig. 2 the utility model bridge-type small stair external diameter stopper measuring tool includes saddle seat 1, thousand points of internal diameter
Table 2, gauge head 3 and lock-screw 4, the bottom surface of the saddle seat 1 are provided with recess 11, and the front end of the recess 11 is provided with step 12, rear end
Inwall is provided with screw 13, and the step 12 is provided with through hole 14 vertically, and the lower section of the step through-hole 14 is provided with open slot 15, institute
The position vertical axial of open slot 15 for stating step 12 is provided with locking screw holes 16, and the gauge head 3 is located at the saddle seat by screw thread
The screw 13 of the rear end inwall of recess 11, the measuring staff of the inside dial indicator 2 penetrates the through hole 14 of the step 12, the locking screw
Nail 4 is twisted the locking screw holes 16 in the step 12 and fastens the inside dial indicator 2.
Preferably, the flatness error≤0.003mm of the plane of 1 bottom surface recess of the saddle seat 11.
When part small stair external diameter seam is measured, saddle seat is positioned over the small stair external diameter seam of part, saddle seat
Under the seam of the origin reference location plane laminating part of recess on locating surface, inside dial indicator probe and gauge head bear against part and stop
Mouth outer ring, by gauge head against mobile saddle seat on the basis of point, reads inside dial indicator measured value, and inside dial indicator measured value is most
The seam external diameter is greatly.This measurer duplicate measurements uniformity is good, and metering system is simple, less demanding to survey crew.This amount
Lamps structure is simple, easy to make, low cost of manufacture, has good practicality during part machining operation.
