Description

Technical Field

[0001] The utility model relates to the field of pipe bending processing equipment, in particular to a non-standard elbow auxiliary measuring device. Background Art

[0002] It is very troublesome to measure the size of elbows with unconventional angles (angles other than 90 degrees). Each bend needs to be manually laid out to measure the size of the elbow. Whether it is a bent pipe or a bend welded with an elbow and a pipe, as long as it is a non-90-degree bend, it is necessary to lay out and find the measurement center point of the elbow. Figure 1 For example, the production process of the pipe is cutting - bending - laying out to find the measurement center point of the elbow - measuring the distance from the center point of the elbow to the two ends of the pipe - cutting the excess length of the pipe according to the drawing size - welding the flange. In this process, the difficulty lies in how to find the measurement center point of the elbow on the pipe that has been bent and formed, because the measurement center point of the elbow is the intersection of the center lines of the straight pipes on both sides of the elbow, not the midpoint of the center arc of the elbow. After the pipe is bent, the measurement center point of the elbow is found by laying out, and the size of the two ends of the elbow that needs to be cut can be determined, but the process of laying out and comparing is time-consuming, especially for projects with more elbows, which require repeated and complicated laying out work, and the operation efficiency is not high. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a non-standard elbow auxiliary measurement device, which can quickly and accurately find the center points of elbows with various diameters and angles without lofting, facilitate subsequent size measurement, and improve work efficiency.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a non-standard elbow auxiliary measuring device, including two groups of clamping seats respectively clamped on the pipes at both ends of the elbow, a first connecting rod is arranged at the center line position of the clamping seat, one end of the first connecting rod is connected to the clamping seat, and the other ends of the two groups of first connecting rods are provided with a rotating seat, and the two groups of rotating seats are rotatably installed on the measuring needle.

[0005] In a preferred solution, the card mounting seat includes two groups of side panels, the tops of the two groups of side panels are connected by a connecting mechanism, and one end of the first connecting rod is connected to the connecting mechanism.

[0006] In a preferred embodiment, the connecting mechanism includes two groups of second connecting rods, which are cross-arranged, and the intersection of the second connecting rods is hingedly connected to the first connecting rod via a pin. One end of the second connecting rod close to the measuring needle is hingedly connected to one end of one group of side panels, and the other end is hingedly mounted on the slider, and a sliding groove that cooperates with the slider is provided on the top of the side panel.

[0007] In a preferred solution, the end of the first connecting rod is hinged to the ends of two groups of third connecting rods respectively, and the other end of the third connecting rod is hinged to the slider.

[0008] The utility model provides a non-standard elbow auxiliary measurement device. Through the hinged connection of the ends of two sets of measuring needles, the two sets of clamping seats can be relatively rotated to adapt to elbows of different angles. The two sets of clamping seats are clamped at both ends of the elbow. The position of the measuring needle is the center of the elbow. The center point of elbows of various diameters and angles can be quickly and accurately found, which is convenient for subsequent dimensional measurement and improves work efficiency. The preferred connection mechanism enables the two sets of side plates to move relative to each other or away from each other, thereby adjusting the distance between the two sets of side plates, which can adapt to the measurement of elbows of different diameters.

[0014] like Figure 2~3 As shown, a non-standard elbow auxiliary measurement device includes two groups of clamping seats 1 respectively clamped on the pipes at both ends of the elbow, and the first connecting rod 2 is set at the center line position of the clamping seat 1, that is, the first connecting rod 2 is set at the center line position of the straight pipe section at both ends of the elbow, and one end of the first connecting rod 2 is connected to the clamping seat 1. The other ends of the two groups of first connecting rods 2 are provided with a rotating seat 201, and the two groups of rotating seats 201 are rotatably mounted on the measuring needle 3, and the measuring needle 3 is arranged perpendicular to the first connecting rod 2. Specifically, the measuring needle 3 is rotatably mounted on the two groups of rotating seats 201 through bearings at the same time, so that the two groups of first connecting rods 2 can rotate along the hinged position with the measuring needle 3, and the two groups of clamping seats 201 can be rotated relative to the measuring needle 3, so that the two groups of clamping seats can be rotated according to different bending angles, so that they can be clamped at both ends of the elbow.

[0015] The card mounting seat 1 includes two groups of side plates 101 , the tops of the two groups of side plates 101 are connected by a connecting mechanism, and one end of the first connecting rod 2 is connected to the connecting mechanism.

[0016] During specific use, the connecting mechanism can be set as a top plate, and the two sets of side plates 101 and the top plate form a U-shaped structure. The width of the card mount 1 is consistent with the outer diameter of the bent pipe. The relative angles of the two sets of card mounts 1 are adjusted and they are turned upside down at both ends of the bent pipe. The position of the measuring needle 3 is the center of the bent pipe.

[0017] The above connection mechanism makes the card-mounting seat 1 only have a fixed size, that is, the distance between the two sets of side plates 101 cannot be adjusted. Therefore, as another preferred embodiment, the connection mechanism includes two sets of second connecting rods 102, the two sets of second connecting rods 102 are cross-arranged, the two sets of second connecting rods 102 have the same length, the intersection is located at the center of the second connecting rods 102, the intersection of the second connecting rods 102 is hingedly connected to the first connecting rod 2 through a pin, one end of the second connecting rod 102 close to the measuring needle 3 is hingedly connected to one end of one set of side plates 101, and the other end is hingedly mounted on the slider 103, and the top of the side plate 101 is provided with a slide groove 104 that cooperates with the slider 103.

[0018] The ends of the first connecting rod 2 are hinged to the ends of the two groups of third connecting rods 105 respectively. The length of the third connecting rod 105 is half the length of the second connecting rod 102. The other end of the third connecting rod 105 is hinged to the slider 203. The slider 203 is a long strip slider. The second connecting rod 102, the slider 203 and the third connecting rod 105 form a parallelogram connecting rod mechanism. The first connecting rod 2 is pushed and pulled to deform the slider 203 and move along the slide groove 104. At the same time, the two groups of side plates 101 are moved relative to or away from each other, thereby adjusting the distance between the two groups of side plates 101 to adapt to the measurement of bent pipes with different diameters.

[0019] During specific use, the slide groove 104 is an inverted “T”-shaped slide groove or a dovetail-shaped slide groove, and the slider 103 moves along the slide groove 104 to prevent the slider 103 from moving upward and out of the slide groove 104 .

[0020] During specific use, pull the first connecting rod 2, adjust the distance between the two groups of side plates 101 of the two groups of clamping seats 1, make the distance between the two groups of side plates 101 of the clamping seats 1 consistent with the outer diameter of the pipes at both ends of the elbow, adjust the relative angle of the first connecting rod 2 corresponding to the two groups of clamping seats 1, and install the two groups of clamping seats 1 on the pipes at both ends of the elbow. At this time, the position corresponding to the measuring needle 3 is the center point of the elbow. According to the design size requirements, the corresponding size position of the measuring needle 3 and the pipes at both ends of the elbow is measured by a measuring ruler, and marked, and then cut at the marked position. After cutting, weld the flanges at both ends of the elbow to complete the processing of the elbow.

[0021] by Figure 1 Take pipe making as an example.

[0022] 1) Cut the material according to the drawing size and leave enough space for bending. The cutting length is 1000mm.

[0023] 2) Input coordinates and use CNC pipe bending machine to bend 70° into shape.

[0024] 3) Clip the two sets of mounting seats 1 onto the bent pipe so that the inner sides of the two side plates 101 are in close contact with the outer wall of the pipe.

[0025] 4) The location of measuring needle 3 is the measurement center point of the elbow.

[0026] 5) Use a ruler to measure the distance from the measuring needle to the end of the pipe and cut off the excess size.

[0027] 6) Weld the flanges together to complete the pipeline production.

[0028] The device can be adapted to the size measurement of elbows with different diameters and angles. It has strong applicability and does not require repeated lofting during the measurement process. It can very intuitively display the position of the elbow measurement center point, thereby improving work efficiency.
