Abstract
The utility model belongs to a marking tool in pipe component machining, mainly used for scribing the intersecting lines of an insertion pipe and a socket pipe when pipes are vertically intersected and welded. The utility model is composed of a central shaft road, a turning block, and a scribing needle. When the utility model is used, the fixing end of the central shaft is arranged on a pipe on which lines need to be drawn; the radius of the scribing needle is fixed; the turning block drives the scribing needle to scribe the intersecting lines of the insertion tube and the socket pipe. Compared with the traditional lofting methods, the marking scriber has the advantages of high efficiency, convenient operation, accurate intersecting lines, and regular intersecting lines.
Description
The utility model belongs to a kind of line tool of pipe element processing.
In pipeline constructions such as existing ventilation, water pipe, coal gas; run into the situation that pipeline vertically passes through mutually through regular meeting; because intersection is a space curve; so the method for unwrapping wire generally is to obtain by the method for descriptive geometry to pass through mutually a little; method by setting-out is plotted on the pipeline then; process again, do loaded down with trivial detailsly like this, also can cause error.
The purpose of this utility model provides a kind of pipe communicated wire and plans, and can be used for the line tool of pipe element processing.This instrument intersection that can directly on pipeline, draw, accurately, convenient.
The utility model is made up of central shaft 1 and turning block 2 and scriber 3.One end wheel 4 is arranged on the central shaft, and the lower end connects with a positioning head 5 screw threads; Turning block 2 can move up and down and drive scriber 3 along central shaft and do 360 ° of rotations around central shaft together, turning block has a scallop 6 on the turning block shown in figure two, figure three, can be used for hinged scriber upper end, adjust the angle of scriber and central shaft, by required radius setting-out; Scriber 3 front ends are broken line shape, and the pin end contacts with tube wall all the time, and guarantee the figure accurately that draws on pipeline.
The utility model is mainly used in pipeline and vertically passes through welding mutually, can be respectively inserting the crossing intersection that draw on pipe and the bell-and-spigot pipe, and is easy and simple to handle with traditional setting out method specific efficiency height mutually, and the intersection that draws is accurate, regular.
Below in conjunction with drawings and Examples structure of the present utility model is described.
Figure one is the utility model structure chart
Figure two is the turning block front view
Figure three is the turning block vertical view
Figure four is a positioning head of the present utility model
The utility model material is the 45# steel, 340 millimeters of central shaft 1 length, diameter is 12 millimeters, and there is 7 millimeters screw thread at two ends, and there is end wheel 4 upper end, connect with central shaft 1 screw thread, lower end positioning head 5 is inversed taper platform shape, positioning head and central shaft 1 thread connection, and head has a projection, 5 millimeters of diameters are in order to the location; 12 millimeters of turning block 2 median pore diameter, be enclosed within on the central shaft, turning block is the chamfer triangle on one side, on one side be fan-shaped, the nail hole and the deep-slotted chip breaker of a location arranged, on fan-shaped in order to adjust the angle of scriber, 6.5 millimeters of nail bore dia and arc groove widths, two holes are arranged on the upper surface of turning block, and 3.5 millimeters of diameters are in order to fixing handwheel 7; 300 millimeters of scriber 3 length, 10 millimeters of diameters, 6.2 millimeters of head bore diameters locate to follow closely 6 millimeters in hole apart from 30 millimeters on head, with nail hole and groove on the scallop of turning block with cooperate, make circular motion with turning block, the scriber cross section is 6 * 10 millimeters, and the scriber bottom is 120 ° broken line shape tip, long 40 millimeters of point, wedge angle is 30 ° of angles, guarantees to contact with tube wall, draws and inserts the intersection of pipe and bell-and-spigot pipe.
