Abstract
A kind of arc measuring rule of simple and easy portable, the utility model relates to the technical field of automobile speed variator piece test.The utility model is the survey instrument in order to overcome existing case of transmission circular arc, and its structure is simple, there is design defect, measuring accuracy low and cannot determine the problem of arc position.Its technical scheme is: it is flat sheet, and its left-hand end is circular arc no-go gage end, and its left side central portion is provided with the first circular positioning datum boss, and its right-hand end is circular arc drift end, and its right side central is provided with the second circular positioning datum boss.The utility model beneficial effect: simple and reasonable, body weight is light, and instrument manufacture difficulty is low, and expense is few, and consumptive material is economized; Measuring method is easily understood, simple operation, measures consuming time short, effectively improves operating efficiency; Can the multiple piece number housing of compatible measurement, reduce ineffective time, enhance productivity, measuring accuracy is high.
Description
Technical field
The utility model relates to the technical field of automobile speed variator piece test.
Background technology
The survey instrument of existing case of transmission circular arc, its structure is simple, but there is design defect, the problem that measuring accuracy is low.Major defect is low to the identification of measurement result, there is certain error to the confirmation of part eligible state.And can only measure arc diameter, and measuring accuracy is poor.And the position degree of circular arc cannot be determined, three-dimensional also cannot be measured.
Summary of the invention
The purpose of this utility model is to provide a kind of arc measuring rule of simple and easy portable, and the utility model is the survey instrument in order to overcome existing case of transmission circular arc, and its structure is simple, there is design defect, measuring accuracy low and cannot determine the problem of arc position.The arc measuring rule of a kind of simple and easy portable of the present utility model, its technical scheme is: it is flat sheet, its left-hand end is circular arc no-go gage end 1, its left side central portion is provided with the first circular positioning datum boss 2, its right-hand end is circular arc drift end 3, and its right side central is provided with the second circular positioning datum boss 4.
The utility model beneficial effect: simple and reasonable, body weight is light, and instrument manufacture difficulty is low, and expense is few, and consumptive material is economized; Measuring method is easily understood, simple operation, measures consuming time short, effectively improves operating efficiency; Can the multiple piece number housing of compatible measurement, reduce ineffective time, enhance productivity, measuring accuracy is high.After application the utility model, a large amount of Measuring Time has been saved in production scene, decreases unworthy working time, improves measuring accuracy and measures efficiency.Avoid because cutter Integrated Chip and the wear and tear defective phenomenon of arc size that causes and machine coordinates initial point change the position offset problem produced, effectively solve the difficulty that three-dimensional cannot be measured, solve the hidden danger of quality for many years existed.

Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is the utility model one-piece construction schematic diagram in use.
Embodiment
Embodiment one: composition graphs 1, Fig. 2 illustrate present embodiment, the technical scheme of present embodiment is: it is flat sheet, its left-hand end is circular arc no-go gage end 1, its left side central portion is provided with the first circular positioning datum boss 2, its right-hand end is circular arc drift end 3, and its right side central is provided with the second circular positioning datum boss 4.
Principle of work:
Composition graphs 3 illustrates, the circular positioning datum boss 4 of first circular positioning datum boss 2 or the second of the present utility model to be loaded in case of transmission in casing part pilot hole 5, circular arc drift end 3 is near circular arc position and part is close in lower surface, there is gap circular arc no-go gage end 1 lower surface, cannot circular arc be pressed close to, represent that this part is pieces O.K..In case of transmission production line BA14R casing R13 the measurement of R28 arc position and size.
