Abstract
The utility model discloses a tool for drawing a circle on a curved surface, which comprises a bracket (2), a circular column (3) passing through the bracket (2) and having a conical bottom end, a rod member (1) connected to the circular column (3), a connecting sleeve (9) connected with the end part of the rod member (1) and a drawing rod (8) connected with the connecting sleeve (9). The circular column (3) is movably connected with the bracket (2) through a bearing (5), a radial through hole is formed at the upper end of the circular column (3), the rod member (1) passes through the through hole, a bolt hole is formed in the vertical position of the through hole in the radial direction, and a bolt (6) is fitted inside the bolt hole and is butted against the rod member (1). The tool provided by the utility model has simple structure and convenient use, and can ensure the quality of circle drawing and setting out on the curved surface.
Description
Technical field
The utility model relates to a kind of curved surface and draws the sired results tool.
Background technology
In field of machining, usually pipe to be communicated on another root pipe, need dig out on the connected tube surface before the processing one with the big or small adaptive hole of tube connector, because the pipe surface is a cylinder, can't draw the circle setting-out with common compasses, must use curved surface and draw round specific purpose tool, otherwise since setting-out not the brigadier cause welding difficulty, perhaps cause pipeline to scrap.
The utility model content
The utility model provides one one kinds of curved surfaces to draw the sired results tool, can not only draw circle on cylinder, can also draw circle at sphere and other irregular surface.
The technical solution adopted in the utility model is: curved surface is drawn the sired results tool, it is characterized in that it comprises support, passes cylinder that support and bottom are taper, is connected in rod member on the cylinder, is connected the adapter sleeve of Rod end and is connected the bar of drawing on the adapter sleeve, cylinder connects by bearing and support are movable, the cylinder upper end is provided with radial direction through hole, rod member passes through hole, hanging down of through hole radially is provided with screw from the position, is combined with screw in the screw, and screw is squeezed on the rod member.
Adopt technique scheme, be actually the projection theory of utilizing circle, cylinder is most advanced and sophisticated aims at the home position that institute's setting-out of wanting is justified, unclamp the hold-down screw on the rod member, the slip rod member is determined to be screwed rod member behind the setting-out radius according to graduation mark, keep cylinder perpendicular to the circle centre position curved surface as far as possible, rotate rod member, draw bar awl point and can on curved surface, draw vestige down, can finish setting-out.
For making things convenient for sizing, rod member is provided with scale marker.By scale marker, can accurately know the radius of setting-out like this.
Rotate for convenient, the upper end of cylinder is connected with handle.Hold handle when rotating like this, the convenient rotation.
In sum, the beneficial effects of the utility model are: the curved surface that utilizes round projection theory to make is drawn the sired results tool, and it is simple in structure, and is easy to operate, can draw round setting-out at arbitrary surfaces.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1, rod member, 2, support, 3, cylinder, 4, latch, 5, bearing, 6, screw, 7, handle, 8, draw bar, 9, adapter sleeve.
The specific embodiment
The utility model curved surface is drawn the sired results tool, as shown in Figure 1, it comprises support 2, pass cylinder 3 that support 2 and bottom are taper, be connected in rod member 1 on the cylinder 3, be connected the adapter sleeve 9 of rod member 1 end and be connected and draw bar 8 on the adapter sleeve 9, cylinder 3 is by bearing 5 and 2 movable connections of support, cylinder 3 upper ends are provided with radial direction through hole, and rod member 1 passes through hole, and the upright position of through hole radially is provided with screw, be combined with screw 6 in the screw, screw 6 is squeezed on the rod member 1.Rod member 1 is provided with scale marker.The upper end of cylinder 3 is connected with handle 7.Latch 4 is to be used for support 2 is carried out fixed stop.
The utility model in use, determine the setting-out radius earlier, unclamp rod member 1 hold-down screw 6, adjust rod member according to the graduation mark on the rod member 1, on the setting-out part, determine the setting-out center of circle again, to bore point and aim at the setting-out center of circle, adjust handle 7 and support 2, make cylinder 3 axial lines and circle centre position curved surface keep vertical, more stable in operating process in order to make cylinder 3, can be at aperture of setting-out circle centre position subdrilling, to bore point and put in the aperture, revolving rod 1 then, carries out positive and negative 360 ° of rotations, can be during rotation with have gentle hands by drawing bar 8, stroke bar 8 following stroke points are left a trace on the setting-out part and are the setting-out circle.
