Abstract
The utility model provides go-no go caliper gauge used for low-conical degree circular conical surface detection. With the go-no go caliper gauge adopted, accurate and real-time detection of a workpiece in a machining process can be realized; standstill in production caused by the only reliance on three-coordinate detection can be avoided; a new product debugging cycle can be effectively shortened; the detection of the go-no go caliper gauge will not damage a workpiece to be detected; and the problem of mismatching between detection results and three-coordinate detection data can be solved. The go-no go caliper gauge used for the low-conical degree circular conical detection is characterized in that the whole go-no go caliper gauge is reverse C-shaped; the overall thickness of the go-no go caliper gauge is the distance from a section to be detected to a detection reference plane; an upper edge and a lower edge of a C-shaped opening is horizontally parallel to each other; the external side ends of the inner walls of the upper edge and the lower edge are both provided with a go-end limiting edge; and the internal side end of each go-end limiting edge is provided with a no go-end limiting edge.
Description
Technical field
The utility model relates to the pick-up unit field of combustion machine pneumatic plant guide vane, especially relates to the pick-up unit field of the combustion machine pneumatic plant guide vane department of assembly circle of position conical surface, is specially a kind of stop-pass calliper that detects for low tapering circular conical surface.
Background technology
combustion machine pneumatic plant guide vane is positioned at department of assembly's circle of position conical surface 5 at two ends, 6 are low tapering circular conical surface, see Fig. 1, its machining precision is high, the processing of this circular conical surface mainly with numerical control turning and cylindricalo grinding as main manufacturing process, it need to can directly be measured in real time work status and obtain measurement data on lathe, and the machining precision that finally guarantees of the adjustment of carrying out accordingly machined parameters, at present international examining report is all to submit the three-dimensional testing result as the approval foundation, but general processing enterprise can not be equipped with expensive three-dimensional detector, therefore usually need to be with the product censorship, and it is time-consuming that three-dimensional detects complex operation, therefore easily cause to produce and pause, only detect data according to three-dimensional in the new product debug phase especially and adjust cutting parameter, its debugging cycle is long, in actual production, also there is processing enterprise to adopt traditional cubing to measure in real time, it comprise one with the high precision feeler gauge of outside cone angle as check gauge and a ring gauge that is used for cone angle in the band of workpiece calibration, its shortcoming is that the manufacture difficulty of ring gauge is large, manufacturing cost is high, and the measurement of finding in actual use ring gauge requires high to testing staff's operating gesture, because its tapering is less, operating personnel's undue force easily causes ring gauge or check gauge to take off from workpiece, cause the damage of workpiece conical surface, affect the surface quality of workpiece, be difficult to control simultaneously the applying degree of the ring gauge conical surface and the workpiece conical surface, cause testing result unstable, adopt in addition testing result that traditional cubing obtains and three-dimensional to detect data and do not mate, can't detect data with three-dimensional and carry out deviation ratio pair.
Summary of the invention
For the problems referred to above, the utility model provides a kind of stop-pass calliper for low tapering circular conical surface detection, it can realize accurately the detecting in real time workpiece in process, the production of avoiding only relying on the three-dimensional detection to cause pauses, effectively shorten the new product debugging cycle, and its detection can not damage workpiece for measurement, and can solve testing result and the unmatched problem of three-dimensional detection data.
Its technical scheme is such, it is characterized in that: its integral body is instead " C " shape, its integral thickness is that cross section to be detected is to the distance between the detection reference face, the top of described C shape opening be below horizontal parallel, the outboard end of described top, following inwall is provided with the go side position-limited edge, and the medial extremity of described go side position-limited edge is provided with the not-go-end position-limited edge.
It is further characterized in that:
Distance between described top and following go side position-limited edge is the design greatest wear dimension limit in cross section to be detected;
Distance between described top and following not-go-end position-limited edge is the design minimum dimension in cross section to be detected;
Described go side position-limited edge, not-go-end position-limited edge are made chamfer with a side-locating face respectively.
A kind of stop-pass calliper for low tapering circular conical surface detection of the utility model, it is simple in structure, and is easy to use, can realize the real-time detection in processing or debug process, thereby improves the efficient of debugging, processing; And because its go side position-limited edge, not-go-end position-limited edge are made chamfer with a side-locating face respectively, can effectively avoid other position of conical surface entity, avoid interfering, reduce it to the damage of the conical surface, guarantee the applying of locating surface and detection reference face, guarantee the accuracy of detection architecture; In addition, its detection position is identical with the three-dimensional detection position, and the evaluation mechanism that detects with three-dimensional is also identical, so it can keep the consistance of testing result and three-dimensional testing result, is convenient to carry out verification with the three-dimensional testing result and contrasts.

Embodiment
See Fig. 2 and Fig. 3, its integral body of stop-pass calliper that the utility model is used for low tapering circular conical surface detection is instead " C " shape, its integral thickness d is that cross section to be detected is to the distance between detection reference face M, the top 1 of described C shape opening is horizontal parallel with following 2, the outboard end of top 1, following 2 inwall is provided with go side position-limited edge 3, the medial extremity of go side position-limited edge 3 is provided with not-go-end position-limited edge 4, and the distance L between top 1 and following 2 go side position-limited edge 3 is the design greatest wear dimension limit in cross section to be detected; Distance between top 1 and following 2 not-go-end position-limited edge
lDesign minimum dimension for cross section to be detected; Go side position-limited edge 3, not-go-end position-limited edge 4 are made chamfer 8,9 with a side-locating face A respectively.Use when detecting, see Fig. 4, with a side-locating face A of the stop-pass calliper 7 reference field A ＇ near blade to be measured, keep the profile circle in cross section to be measured parallel with the side-locating face A that stop-pass detects calliper, whether the size of measuring this cross section circle falls into interior the getting final product of scope that special-purpose stop-pass detects calliper.In Fig. 1, m1 is that cross section M1 to be detected is to the distance between detection reference face M, m2 is that cross section M2 to be detected is to the distance between detection reference face M, m is that the workpiece for measurement outermost face is to the distance between detection reference face M, d1 is workpiece for measurement outermost end cross section profile diameter of a circle, d2 is workpiece for measurement innermost end portions cross section profile diameter of a circle, and in Fig. 3, n is not-go-end position-limited edge width.When needs adopt the three-dimensional detector to carry out verification to testing result, only need directly scan cross section to be detected cylindrical with the three-dimensional detector, the detection architecture of three-dimensional testing result and above-mentioned employing special use cartoon calliper is carried out verification compare and get final product.
