Abstract
The device is a large flange circle-drawing tool, of which an adjusting plate is arranged at the face of a rectangular support plate, which assumes an adjustable connection; one end of the adjusting plate is provided with a scratch awl, of which the height is adjustable; the tow back ends of a rolling body is vertical to a support plate. The central distance of the rolling body is adjustable, which comprises a rolling sleeve and a positioning shaft; a position limit step is arranged at one end of the rolling sleeve near the support plate. The utility model is used for a large flange, which can draw a circle without identifying the center of a flange; the concentric circle in different diameters can be drawn on different sizes of flanges by means of adjusting central distance of the rolling body and position of the scratch awl, which is convenient for drawing circle rapidly and accurately.
Description
Technical field
The utility model relates to a kind of mechanical processing industry scoring tool, in particular for stroke sired results tool of big ring flange.
Background technology
The connecting hole of using the ring flange of connector as plant equipment always generally is distributed on the concentric circles of ring flange, before the processing, need mark this concentric circles earlier, determine the connecting hole center again, traditional method be with wooden unit or parallels plug in the interior circle of ring flange, find out the ring flange center with geometric method, again with the circle of planing greatly.Run into the big ring flange of diameter more than 1m, this method bothers very much, and it is time-consuming to require great effort, and the center of circle is difficult for drawing standard, an influence stroke circle accuracy.
The utility model content
The technical problems to be solved in the utility model provides a kind of big ring flange and draws the sired results tool, can mark the concentric circles of different-diameter on big ring flange easily and fast, exactly with this instrument.
The technical solution of the utility model is: be provided with a rectangle support plate in this instrument, be provided with adjustable plate in the front of support plate, both become adjustable connection, and adjustable plate is provided with scriber, and a rolling element perpendicular to support plate is respectively established at the two ends, the back side of support plate.
Further scheme is the long lumbar hole that is respectively equipped with on described support plate, the adjustable plate along its length, and support plate, adjustable plate are connected by the screw that passes long lumbar hole, nut; Described scriber is threaded with adjustable plate, and is provided with locking nut; Described rolling element is the rolling cover that is enclosed within on the locating shaft, and locating shaft and support plate are clamped by nut, and the support plate connecting portion has long lumbar hole along its length; Described rolling cover is provided with limited step near an end of support plate.
During use, mix up the centre-to-centre spacing of two rolling elements earlier, with its inside and outside circle that blocks ring flange, do not have the gap substantially, regulate the scriber position again, on the other hand press down scriber, a hand propelled support plate can mark the concentric circles of different-diameter on the ring flange of different size.Draw circle with this instrument, need not to find out the ring flange center, adjust easily, easy to operate, quick, there is not the gap between each movement parts substantially, guarantee to draw the circle precision.Described rolling element adopts the cover that rolls, and the one end has limited step, then further improves the stationarity of drawing in the circle, reduces frictional resistance.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
As figure, the front of rectangle support plate 1 is provided with adjustable plate 2, and both are connected by screw, nut, and connecting portion has respectively along the long lumbar hole of support plate, adjustable plate length direction.The external part of adjustable plate is provided with scriber 4, and its height is adjustable by screw thread and locking nut.A rolling element perpendicular to support plate is respectively established at two ends, the support plate back side, and this rolling element is by the cover 3 that rolls, and locating shaft 5 constitutes, and locating shaft passes the long lumbar hole of support plate, and by the screw thread and the nut clamping of one end, the cover that rolls has limited step by support plate one end.
