[0002] When making the fan-shaped hole in the middle of the sprocket model, it is not easy to draw the fan-shaped hole due to the existence of the middle hub. Even if it is barely drawn with a compass and a high-level line drawing method, the accuracy of its size is not easy to measure. Use the internal When measuring with a card, it will be hindered by the outer ring of the sprocket model, and when using a wild card, it will be hindered by the hub of the sprocket model

The invention discloses a telescopic measuring and drawing gauge. The telescopic measuring and drawing gauge comprises a transverse ruler and two moving rulers slidably mounted on the transverse rulers in a sleeving mode. Scale lines are marked on the transverse ruler and the moving rulers correspondingly, the two moving rulers can slide towards the two ends of the transverse ruler correspondingly, and first positioning devices are arranged between the moving rulers and the transverse ruler; each moving ruler is slidably sleeved with a sliding sleeve, and second positioning devices are arranged between the moving rulers and the sliding sleeves; a vertical rod is assembled on each sliding sleeve in a vertical sliding mode, and third positioning devices are arranged between the sliding sleeves and the vertical rods; and a steel needle or a line-drawing pen are arranged at the lower end of each vertical rod, and fourth positioning devices are arranged between the steel needles or the line-drawing pens and the vertical rods. The telescopic measuring and drawing gauge is suitable for an annular face with the center and the periphery which are different in height, the measuring gauge andline-drawing are combined, under the situation that a tool is not replaced, the functions of measuring and line-drawing can be achieved, and the telescopic measuring and drawing gauge can be used forprecise line-drawing of a sector hole in the middle of a chain wheel model.
Description
technical field [0001] The invention belongs to the technical field of model processing, and in particular relates to a scalable drawing gauge. Background technique [0002] When making the fan-shaped hole in the middle of the sprocket model, it is not easy to draw the fan-shaped hole due to the existence of the middle hub. Even if it is barely drawn with a compass and a high-level line drawing method, the accuracy of its size is not easy to measure. Use the internal When measuring with a card, it will be hindered by the outer ring of the sprocket model, and when using a wild card to measure, it will be hindered by the hub of the sprocket model. Contents of the invention [0003] In order to solve the above problems, the present invention provides a retractable measuring gauge, which can realize accurate drawing of the fan-shaped hole in the middle of the sprocket model. [0004] In order to achieve the above object, the present invention adopts the following technical so...
