Description

Technical Field

[0001] This application relates to the field of high-pressure oil pipe testing technology, and more specifically, to a pipe fitting angle testing device. Background Technology

[0002] In modern industry, high-pressure oil pipes are widely used in fuel injection systems, hydraulic systems, and other fields. The accuracy of their shape and dimensions directly affects system performance and safety. Traditional inspection methods mainly rely on manual measurement or simple tools, which suffer from low efficiency, poor accuracy, and susceptibility to human factors.

[0003] A search revealed that Chinese patent CN207763666U discloses a three-coordinate positioning fixture for measuring high-pressure oil pipes. This device can adjust the position of the V-block by adjusting the bolts, and combined with the self-centering positioning effect of the V-shaped positioning surface on the high-pressure oil pipe, the three-coordinate positioning fixture can be adjusted according to the size and spatial shape of the high-pressure oil pipe itself, ensuring that the high-pressure oil pipe under test will not deform during measurement, thus improving the detection accuracy.

[0004] When using the above-mentioned device to inspect high-pressure oil pipes, it can only detect the bending shape of the pipe fittings, but cannot detect the position of the pipe fitting ends. In view of this, we propose a pipe fitting angle detection device. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a pipe fitting angle detection device to solve the problems mentioned in the background art.

[0007] 2. Technical Solution

[0008] This application is achieved through the following technical solution:

[0009] A pipe fitting angle detection device includes a base, a limiting post fixedly installed on the top of the base, a limiting groove formed on the limiting post, detection posts on both sides of the limiting post, the detection posts fixedly installed on the base, a detection shaft slidingly passing through the upper part of the detection post, a threaded part at the end of the detection shaft near the limiting post, a detection nut threadedly connected to one end of the detection shaft, a detection plate connected to the end of the detection shaft away from the limiting post, the detection plate moving in a plane perpendicular to the axial direction of the detection shaft, and a marking plate fixedly installed on the detection post.

[0010] As an optional solution to the technical solution of this application, the detection shaft is fixedly connected to a limiting ring, which is disposed on one side of the threaded portion.

[0011] As an optional solution to the technical solution of this application, the upper surface of the marking plate is provided with a marking groove, and the detection plate is adapted to the marking groove.

[0012] As an optional solution to the technical solution of this application, the detection plate is rotatably connected to the outside of the detection shaft.

[0013] As an optional solution to the technical solution of this application, two limiting grooves are provided, and the two limiting grooves are respectively opened on the upper surface and the side surface of the detection column.

[0014] As an optional solution to the technical solution of this application, a fixing post is provided between the limiting post and the detection post. The fixing post is fixedly installed on the base, and a fixing rod is horizontally slidably connected to the upper part of the fixing post. A fixing groove is opened on the end face of the fixing rod.

[0015] As an optional solution to the technical solution in this application, both the limiting post and the detection post are fixedly installed on the base with bolts.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] This application uses a sliding connection of a detection shaft to the upper part of the detection column. When detecting the bending shape of the high-pressure oil pipe by rotating the detection nut onto the detection shaft, the length of the detection shaft penetrating into the detection nut can be observed through the set marking groove and detection plate, thereby determining the position of the end of the high-pressure oil pipe. If the detection plate cannot enter the marking groove, it indicates that the position of the end of the high-pressure oil pipe does not meet the standard. Attached Figure Description

[0022] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0023] Please see Figure 1 and Figure 2This application provides a pipe fitting angle detection device, including a base 1, a limiting post 2 fixedly installed on the top of the base 1, a limiting groove 201 opened on the limiting post 2, detection posts 3 on both sides of the limiting post 2, the detection posts 3 fixedly installed on the base 1, a detection shaft 4 slidingly passing through the upper part of the detection post 3, a threaded part at one end of the detection shaft 4 near the limiting post 2, a detection nut 5 threadedly connected to one end of the detection shaft 4, a detection plate 6 connected to the end of the detection shaft 4 away from the limiting post 2, the detection plate 6 moving in a plane perpendicular to the axial direction of the detection shaft 4, and a marking plate 7 fixedly installed on the detection post 3.

[0024] When inspecting the high-pressure oil pipe, first, place the inspection nut 5 on both ends of the high-pressure oil pipe, then place the high-pressure oil pipe in the limiting groove 201 of the limiting post 2, move the inspection nut 5 to the end of the inspection shaft 4, and rotate the inspection nut 5 to the outside of the threaded part on the inspection shaft 4. If the inspection nut 5 can be smoothly rotated to the outside of the threaded part on the inspection shaft 4, it indicates that the bending shape of the high-pressure oil pipe meets the standard. After the inspection nut 5 is rotated to the outside of the threaded part on the inspection shaft 4, observe the relative positional relationship between the inspection plate 6 and the marking plate 7 to determine whether the length of the end of the high-pressure oil pipe meets the standard.

[0025] Preferably, the detection shaft 4 is fixedly connected to a limiting ring 401, which is located on one side of the threaded part. The user can determine whether the bending shape of the high-pressure oil pipe meets the standard by observing the contact between the detection nut 5 and the limiting ring 401.

[0026] Preferably, the upper surface of the marking plate 7 has a marking groove 701, and the detection plate 6 is adapted to the marking groove 701. The detection plate 6 is rotatably connected to the outside of the detection shaft 4. When the detection nut 5 is rotated, the detection shaft 4 can drive the detection plate 6 to move towards the limiting post 2. If the length of the high-pressure oil pipe end meets the standard, the detection plate 6 can move along the upper surface of the marking plate 7 into the marking groove 701. If the length of the high-pressure oil pipe end is greater than the set standard, the high-pressure oil pipe end will abut against the detection shaft 4, preventing the detection plate 6 from entering the marking groove 701.

[0027] Preferably, there are two limiting grooves 201, which are respectively opened on the upper surface and side of the detection column 3. A fixing column 8 is provided between the limiting column 2 and the detection column 3. The fixing column 8 is fixedly installed on the base 1. A fixing rod 9 is horizontally slidably connected to the upper part of the fixing column 8. A fixing groove 901 is opened on the end face of the fixing rod 9.

[0028] When fixing the high-pressure oil pipe through the limiting groove 201, the high-pressure oil pipe can also be fixed through the fixing groove 901 at the end of the fixing rod 9, which increases the fixing effect of the high-pressure oil pipe and prevents the high-pressure oil pipe from moving during the testing process.

[0029] Preferably, both the limiting post 2 and the detection post 3 are fixedly installed on the base 1 with bolts, which makes it convenient for users to replace the limiting post 2 and the detection post 3, and is suitable for testing high-pressure oil pipes of different specifications.
