Description

Technical Field

[0001] This application relates to the field of pipe measurement technology, specifically to a pipe straightness testing device. Background Technology

[0002] Pipes, as important industrial materials, are widely used in construction, machinery, chemical industries, and are also a key material in the manufacture of sports equipment such as fishing rods. Straightness is one of the important indicators for evaluating pipe quality, directly affecting subsequent processing, installation, and performance. However, existing pipe straightness testing technologies still have many shortcomings and cannot meet the ever-increasing production demands. Traditional testing methods mostly rely on manual visual inspection or simple mechanical devices for judgment. Manual inspection is not only highly subjective, inaccurate, and inefficient, but also difficult to accurately quantify straightness errors and cannot meet the needs of mass production. Especially for slender pipes such as fishing rods, which have extremely high straightness requirements, existing testing methods are ineffective.

[0003] Therefore, it is of great significance to develop a pipe straightness testing device that is simple in structure, easy to operate, and has high testing accuracy. Utility Model Content

[0004] The purpose of this application is to provide a pipe straightness testing device.

[0005] The embodiments of this application can be implemented through the following technical solutions:

[0006] A pipe straightness testing device includes: a base on which a first track and a second track are provided, which are parallel to each other; a clamping mechanism and a supporting mechanism coaxially arranged on the first track, wherein the clamping mechanism and the supporting mechanism jointly support and position the pipe to be tested so that the axis of the pipe is parallel to the first track; and a measuring mechanism slidably connected to the second track, wherein the measuring mechanism is used to measure whether the distance from the outer side of the pipe to the measuring reference is consistent along the axial direction of the pipe.

[0007] Furthermore, the clamping mechanism includes a clamping part and a clamping base; the clamping base is disposed on the first track, the clamping part is coaxially disposed with the pipe to be tested, one end of the clamping part is rotatably connected to the clamping base, and the other end is provided with a clamp for detachable connection with the end of the pipe to be tested.

[0008] Furthermore, the chuck is a variable-diameter movable chuck.

[0009] Furthermore, the number of the support mechanisms is at least one, and they are arranged coaxially on the first track on the same side as the clamping mechanism.

[0010] Furthermore, the support mechanism is provided with a support space that is adapted to the outer diameter of the pipe to support and position the pipe.

[0011] Furthermore, the support mechanism includes a support base, a first support part, and a second support part. The lower end of the support base is connected to the first track, and the upper end is provided with an opening. The opening gradually narrows from top to bottom. The first support part and the second support part are symmetrically arranged on both sides of the opening, forming a support space for accommodating the pipe together with the opening.

[0012] Furthermore, the opening is V-shaped; the first support portion and the second support portion have the same shape, both being disc-shaped.

[0013] Furthermore, the support base has symmetrical horizontally extending grooves on both sides of the opening, and the first support part and the second support part are slidably connected to the support base through the grooves.

[0014] Furthermore, the support base is also provided with scale lines, which are adapted to the extension direction of the slide groove.

[0015] Furthermore, the measuring mechanism includes a caliper base and a vernier caliper. The bottom end of the caliper base is slidably connected to the second track, and the upper end is connected to the vernier caliper. The measuring direction of the vernier caliper is perpendicular to the extension directions of the first track and the second track.

[0016] The pipe straightness testing device provided in the embodiments of this application has at least the following beneficial effects:

[0017] This application sets up a first and a second track that are parallel to each other. With the help of a clamping mechanism and a support mechanism, the pipe axis is made parallel to the first track. By sliding the measuring mechanism on the second track, the distance from the outer side of the pipe to the measuring reference can be accurately measured along the pipe axis. By comparing the consistency of the distances at each point, the straightness of the pipe can be accurately determined to meet the standard. The structure is simple and easy to operate. Compared with the traditional method of manually checking straightness, it significantly improves the detection accuracy and efficiency and can meet the detection needs of mass production.

[0018] The variable diameter clamp and variable support space design of the support mechanism can adapt to the testing of pipes with different diameters, which greatly improves the versatility of the testing device and reduces the trouble and cost of changing testing equipment for different pipe diameters.

[0019] The support mechanism of this application combines a unique V-shaped open support base and a disc-shaped support design to provide stable and reliable support and positioning for the pipe, prevent the pipe from shaking or shifting during the testing process, ensure the accuracy and stability of the measurement data, and further improve the reliability of the test results.

[0030] Combination Figure 1 and Figure 2 As shown in the figure, this application provides a pipe straightness testing device, which includes a base 1, a clamping mechanism 2, a supporting mechanism 3, and a measuring mechanism 4. A first track 11 and a second track 12 are arranged parallel to each other on the base 1. The clamping mechanism 2 and the supporting mechanism 3 are coaxially arranged on the first track 11 along the extension direction of the first track 11. The clamping mechanism 2 and the supporting mechanism 3 together provide support and positioning for the pipe to be tested, so that the axis of the pipe to be tested is parallel to the extension direction of the first track 11. The measuring mechanism 4 is slidably connected to the second track 12. It is used to measure the distance between the outer side of the pipe and the measuring reference along the axial direction of the pipe. By providing quantitative data, it is determined whether the distances are consistent, thereby determining the straightness of the pipe.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, the clamping mechanism 2 includes a clamping part 21 and a clamping base 22. The clamping base 22 is disposed on the first track 11. One end of the clamping part 21 is connected to the clamping base 22, and the other end is provided with a chuck 211. The chuck 211 is used for detachable connection with the end of the pipe to be tested. When connected, the clamping part 21 and the pipe to be tested are coaxially arranged. In some preferred embodiments, the chuck 211 is a variable-diameter movable chuck, which can be used to clamp pipes of various diameters. In some preferred embodiments, one end of the clamping part 21 is connected to the clamping base 22. The clamping part 21 is rotatably connected relative to its axis, thereby rotating the pipe to be tested relative to its axis by rotating the clamping part 21, so as to more conveniently and quickly detect the straightness of different sides of the pipe. In some specific embodiments, the end of the clamping part 21 near the clamping base 22 is provided with a rotating shaft 212. The clamping base 22 is provided with a through hole that is adapted to the rotating shaft 212. The rotating shaft 212 passes through the through hole and is limited by the locking nut 213, thereby realizing that the relative position of the clamping part 21 and the clamping base 22 is fixed along the extension direction of the pipe axis and rotatably connected relative to the axis.

[0032] Furthermore, such as Figure 4As shown, the support mechanism 3 includes a support base 31, a first support part 32, and a second support part 33. The bottom end of the support base 31 is disposed on the first track 11, and the top end of the support base 31 is provided with an opening. The opening gradually narrows from top to bottom. The first support part 32 and the second support part 33 are symmetrically disposed on the support base 31 on both sides of the opening. The sides of the first support part 32 and the second support part 33 together with the opening form a support space adapted to the outer diameter of the pipe to be tested, so as to further realize the support and positioning of the pipe.

[0033] In some alternative embodiments, the number of the support mechanisms 3 may be one, two or more, which are coaxially arranged sequentially on one side of the clamp 211 to further improve the positioning accuracy and support stability of the pipe to be tested.

[0034] In some preferred embodiments, the opening of the support base 31 is V-shaped, and the first support part 32 and the second support part 33 have the same shape, both being disc-shaped. The support space formed in this way can better achieve the support stability of the pipe and prevent it from swaying relative to each other. In addition, when the support part is disc-shaped, it is in point contact with the outer wall of the pipe, which can reduce frictional resistance and minimize the interference of support factors on the straightness measurement of the pipe, so that the measurement results more accurately reflect the actual straightness of the pipe.

[0035] In some preferred embodiments, the first support portion 32 and the second support portion 33 can move horizontally relative to the support base 31. Specifically, horizontally extending grooves 312 can be provided at corresponding positions on both sides of the opening of the support base 31. The relative movement of the first support portion 32 and the second support portion 33 can be achieved through the grooves 312. The size of the support space can be adjusted by the movement of the two support portions to adapt to the support of pipes with different diameters.

[0036] In some preferred embodiments, the slide 312 is also provided with scale lines 311, thereby enabling more precise adjustment of the size of the support space;

[0037] Furthermore, the measuring mechanism 4 can be a conventional device capable of measuring distance, such as a laser displacement sensor, a contact displacement sensor, or a caliper. In some preferred embodiments, the measuring mechanism 4 includes a caliper base 41 and a vernier caliper 42. The bottom end of the caliper base 41 is slidably connected to the second track 12, and the upper end of the caliper base 41 is connected to the vernier caliper 42. The vernier caliper 42 is configured such that its measuring direction is perpendicular to the extension directions of the first track 11 and the second track 12. That is, when the inspection is in progress, the distance between the outer wall of the pipe to be inspected and the measurement reference set on the vernier caliper 42 at that position can be measured by the vernier caliper 42. Furthermore, as the measuring mechanism 4 slides on the second track 12, the distance between the outer wall of the pipe to be inspected and the measurement reference set on the vernier caliper 42 at different positions can be measured. By comparing the consistency of the distances measured at various locations, the straightness of the pipe to be inspected can be determined.

[0038] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
