technical field

The utility model relates to a positioning and marking instrument, in particular to a positioning and marking instrument for an eccentric nozzle on a head and a cylinder body.

Background technique

At present, the traditional method of marking the head connecting pipeline and the obliquely inserting pipeline of the pressure vessel adopts the method of lofting and unfolding to draw the line, that is, the measured size after projection is drawn on the model drawing. The traditional method is time-consuming and laborious, especially when encountering When scribing large-diameter pipes, large-diameter eccentric or oblique intubation pipes, the accuracy of lofting cannot be guaranteed, and the efficiency is low. When the scribing work is carried out on the equipment head, because there is a certain shape deviation between the actual formed head and the theoretical shape, the connection line obtained by the traditional method of lofting and unfolding does not conform to the actual situation, which brings difficulties to the scribing work. Certain difficulty; Therefore be badly in need of developing a kind of scribing simple, high operating efficiency end cap and cylinder upper eccentric nozzle positioning scribing instrument, through retrieval, do not find identical or similar technical scheme with the utility model.

Utility model content

The technical problem to be solved by the utility model is to provide an instrument for locating and marking the eccentric nozzle on the head and cylinder with simple marking and high operating efficiency.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is: an eccentric nozzle positioning and marking instrument on the head and the cylinder body, and its innovative point is that it includes a circle center positioning disc, a rotating sleeve assembly and an infrared ray cantilever rod;

The center positioning disc includes a disc body, a sleeve A and a positioning round rod A; the sleeve A and the positioning round rod A are vertically welded to the center of the upper end and the lower end of the disc body respectively;

The rotating casing assembly includes a casing B arranged horizontally, a support cone vertically arranged on both sides of the lower end of the casing B, and a positioning round rod B; Inside the casing A, and parallel to the support cone; the distance between the positioning round rod B and the support cone is smaller than the radius of the disc body;

The infrared cantilever rod includes a cantilever rod body, a scanning pen support ring welded on the end of the cantilever rod body, and an infrared scanning pen installed on the support ring; the cantilever rod body is plugged and fitted in the casing B; The scanning pen is perpendicular to the cantilever rod body.

Further, two threaded holes are provided on the upper end of the sleeve B, and an adjusting bolt is installed respectively.

Further, the positioning round rod B has the same length as the supporting cone.

The utility model has the advantages of:

1) The eccentric nozzle positioning and marking instrument on the head and cylinder body is simple in structure, easy to manufacture and use, and low in cost. Changing the angle between the positioning rod A on the disc body and the part to be marked can be applied to eccentric tubes and oblique intubation tubes of various angles;

2) There are two threaded holes on the upper end of the casing B, and an adjusting bolt is installed respectively, which can adjust the extension length of the cantilever rod, so that it can be applied to the marking work of the connecting pipes of various diameters, and has a wide range of uses;

3) The length of the positioning round rod B is the same as that of the supporting cone, which is convenient for the cantilever rod to avoid large shaking when rotating around the axis and improve the accuracy.

Fig. 1 is a structural schematic diagram of an eccentric nozzle positioning and marking instrument on the head and cylinder of the utility model.

detailed description

As shown in Figure 1, the utility model discloses an eccentric nozzle positioning and marking instrument on the head and cylinder body, which includes a circle center positioning disk, a rotating sleeve assembly and an infrared cantilever rod connected in sequence.

The circle center positioning disk includes a disk body 12, a casing A11 and a positioning round bar A13;

The rotating bushing assembly includes a bushing B21 arranged horizontally, a support cone 23 vertically arranged on both sides of the lower end of the bushing B21, a positioning round rod B22 and an adjusting bolt 24; 24. The length of the positioning round rod B22 is greater than the length of the sleeve A11, and it is inserted into the sleeve A11 and parallel to the support cone 23; the length of the positioning round rod B22 is the same as that of the support cone 23, and the distance between them is smaller than the disc The radius of the body 12 .

The infrared cantilever rod includes a cantilever rod body 31, a scanning pen support ring 32 welded on the end of the cantilever rod body 31, and an infrared scanning pen 33 installed on the support ring 32; The scanning pen 33 is perpendicular to the cantilever body 31 .

When using the eccentric nozzle positioning and marking instrument on the head and cylinder, the rotating sleeve assembly and the center positioning disk are connected through the positioning round rod B22 and the sleeve A11, so that the rotating sleeve assembly can surround the center of the round rod B22 Axis rotation; use the four points drawn on the head or cylinder, and adjust the extension length of the cantilever rod 31 with reference to the size of the nozzle, so that the projection point of the infrared scanning pen 33 coincides with it, and use the adjustment bolt 22 after calibration. Adjust and fix; make the device rotate around the central axis of the round rod B22 to obtain the projection point of the infrared scanning pen 33 on the head or cylinder, and simultaneously draw the line with a scribe pen to obtain a practical connection line.
