Abstract

The present invention relates to the technical field of high-pressure oil pipe detection, and discloses a clamping tooling for high-pressure oil pipe detection, including a tooling assembly. A clamping component for assembling a high-pressure oil pipe body is fixedly arranged inside the tooling assembly. By starting the hydraulic rod, and with the cooperation of the smoothness detection component and the marking component, when there are bumps on the inner wall of the high-pressure oil pipe, the sponge marking block can automatically mark the high-pressure oil pipe body with bumps.

Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure oil pipe detection, and specifically to a clamping tooling for high-pressure oil pipe detection. Background Technique

[0002] The high-pressure oil pipe is a component of the high-pressure oil circuit. It is required that the oil pipe can withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipeline. The vehicle high-pressure oil pipe mainly appears in diesel engines with high-pressure injection and direct-injection gasoline engines with high-pressure injection, and can withstand the oil pressure required during the operation of the engine;

[0003] In the patent application with the application publication number of CN109632213B, it includes an outer detection component and an inner detection component. The inner detection component includes an inner plug and an inner joint. The inner plug is used for sealing connection with one end of the inner oil pipe to be detected, and the inner joint is used for sealing connection with the other end of the inner oil pipe to be detected. A first interface is provided on the inner joint, and the first interface is used for communicating with the inner oil pipe to be detected. The outer detection component includes an outer plug and an outer joint. The outer plug is hermetically sleeved on the inner plug, and the outer plug is used for sealing connection with one end of the outer oil pipe to be detected. The outer joint is hermetically sleeved on the outer joint, and the outer joint is used for sealing connection with the other end of the outer oil pipe to be detected. A second interface is provided on the outer joint, and the second interface is used for communicating with the annular space between the outer oil pipe to be detected and the inner oil pipe to be detected. This invention can be used for the sealing detection of double oil pipes.

[0004] In the prior art including the above patents, after the high-pressure oil pipe is produced, it is necessary to detect its airtightness and the flatness of the inner wall. The existing detection methods usually require step-by-step detection of the high-pressure oil pipe. When performing flatness detection and airtightness detection, the high-pressure oil pipe needs to be repositioned and installed on different detection devices, which increases the operation steps and time and reduces the detection efficiency. During the separate detection process, the high-pressure oil pipe will undergo multiple loading, unloading, and positioning operations, which increases the risk of damage to the oil pipe during the detection process. If there are problems in any link of the flatness detection or airtightness detection, it may lead to misjudgment of the quality of the high-pressure oil pipe. Such misjudgment may cause potential safety hazards because the high-pressure oil pipe needs to withstand great stress and pressure when working in harsh environments such as high pressure and high temperature.

[0041] The sealing component 4 includes two sealing rings 42 fixed to both ends of the propulsion frame 141.

[0042] The smoothness detection component 2 includes a plurality of telescopic touch plates 21 sliding on the first detection disc 15, and the plurality of telescopic touch plates 21 are distributed in an annular array. A telescopic spring 22 is fixedly arranged between each telescopic touch plate 21 and the first detection disc 15.

A torsion spring is arranged between each transmission pipe 26 and the first detection disc 15. The end of the transmission pipe 26 inside the first detection disc 15 is fixedly connected to the end of the transmission pipe 26 inside the second detection disc 16. A plurality of clamping blocks 261 in contact with the plurality of L-shaped clamping blocks 25 are fixedly arranged on the outer arc wall of each transmission pipe 26. A plurality of ventilation holes are formed in each transmission pipe 26. The plurality of telescopic touch plates 21 on the first detection disc 15 and the plurality of telescopic touch plates 21 on the second detection disc 16 are arranged in an interleaved manner. The outer sides of the plurality of telescopic touch plates 21 on the first detection disc 15 and the plurality of telescopic touch plates 21 on the second detection disc 16 are combined into a circle and fit the inner wall of the high-pressure oil pipe body 12 without dead angles;

[0043] The marking component 3 includes an outer fixed pipe 31 fixed on the transmission pipe 26 inside the first detection disc 15. A plurality of spiral transmission plates 32 are fixedly arranged on the outer arc wall of the outer fixed pipe 31;

[0044] The marking component 3 further includes a fixed frame 33 fixed on the tooling assembly 1, and the fixed frame 33 is located on the side of the high-pressure oil pipe body 12 away from the smoothness detection component 2. A transmission cylinder 34 is fixedly arranged inside the fixed frame 33. A plurality of transmission rods 341 are fixedly arranged on the inner wall of the transmission cylinder 34. A piston cylinder 35 is fixedly arranged above the transmission cylinder 34 on the fixed frame 33. One end of the piston cylinder 35 is fixedly provided with a connecting pipe communicated with the transmission cylinder 34. A piston rod 36 penetrating below it is slidably arranged inside the piston cylinder 35. A sponge marking block 37 is fixedly arranged at the bottom end of the piston rod 36.

[0045] A data processing terminal 13 is installed at the top end of the tooling assembly 1, and the data processing terminal 13 is located on the other side of the high-pressure oil pipe body 12. A data processing module is connected between the displacement sensor 23 and the data processing terminal 13 through an electric wire.

[0046] The first detection disc 15 is provided with first telescopic grooves matching with a plurality of telescopic touch plates 21, and a relatively sealed state is formed between the plurality of telescopic touch plates 21 and the inner wall of the first detection disc 15. The second detection disc 16 is provided with second telescopic grooves matching with the plurality of telescopic touch plates 21, and a relatively sealed state is formed between the plurality of telescopic touch plates 21 and the inner wall of the second detection disc 16. Inner sliding grooves matching with L-shaped clamping blocks 25 are formed in each of the plurality of inner fixing plates 24.

[0047] A plurality of spiral drive plates 32 are distributed in an annular array on the outer fixing tube 31, and a plurality of drive rods 341 are distributed in an annular array on the inner wall of the drive cylinder 34.

[0048] The clamping assembly 11 includes a clamping table 111 fixed to the inner wall of the tooling assembly 1. Two clamping seats 113 slide on the clamping table 111. Two electric telescopic rods 112 are installed at the top of the clamping table 111, and the output ends of the two electric telescopic rods 112 are respectively fixedly connected to the two clamping seats 113. The top end of each clamping seat 113 contacts the arc-shaped outer wall of the high-pressure oil pipe body 12.

[0049] When detecting the high-pressure oil pipe body 12, the two ends of the high-pressure oil pipe body 12 can be placed between the two clamping seats 113, and then the two electric telescopic rods 112 are started simultaneously to drive the two clamping seats 113 to slide on the top of the clamping table 111, so as to straighten the high-pressure oil pipe body 12 and make the contact surface between the end of the high-pressure oil pipe body 12 close to the sponge marking block 37 and the sponge marking block 37 be in the same plane. Since the above belongs to the prior art, no more elaboration is made here.

[0050] At this time, the hydraulic rod 14 can be started to drive the propulsion frame 141 fixedly connected to its output end to move towards the high-pressure oil pipe body 12. Under the connection of the sealing ring 42, the first detection disk 15 and the second detection disk 16 fixedly connected to the sealing ring 42 can be driven to move simultaneously. When any one of the two sets of telescopic touch plates 21 on the first detection disk 15 and the second detection disk 16 contacts the convex block on the inner wall of the high-pressure oil pipe body 12, when the telescopic touch plate 21 on the first detection disk 15 contacts the convex block, the telescopic touch plate 21 can be pushed to slide into the first detection disk 15, and at the same time, the telescopic spring 22 is compressed. At this time, the displacement sensor 23 can record the position of the convex block, and the displacement sensor 23 detects the moving distance and sends the data to the data processing terminal 13 through the data processing module. At the same time, the sliding of the telescopic touch plate 21 can drive the inner fixed plate 24 fixedly connected to it to slide, so that the L-shaped clamping block 25 is in close contact with the clamping block 261. Since the position of the clamping block 261 is relatively stationary, the L-shaped clamping block 25 can be pushed to slide inside the inner chute, and at the same time, the return spring 251 is compressed. When the top of the L-shaped clamping block 25 slides below the clamping block 261, under the elastic force of the return spring 251, the L-shaped clamping block 25 can slide towards the clamping block 261 until it slides below the clamping block 261. At this time, under the limiting action of the clamping block 261, the telescopic spring 22 is in a compressed state. With the continuous propulsion of the hydraulic rod 14, when the multiple spiral drive plates 32 on the outer fixed tube 31 contact the multiple drive rods 341 fixed to the inner wall of the drive cylinder 34, the connecting tube inside the drive cylinder 34 can be butted against the outer fixed tube 31 at this time. And since the drive rod 341 is relatively stationary at this time, and the drive rod 341 can push along the outer wall of the spiral drive plate 32 during this process, the outer fixed tube 31 can drive the two drive tubes 26 to rotate respectively around the connection positions of the first detection disk 15 and the second detection disk 16, and at the same time compress the torsion springs fixed between the drive tubes 26 and the first detection disk 15 and the second detection disk 16 respectively. When the self-rotation of the drive tube 26 drives the clamping block 261 to move to a position separated from the L-shaped clamping block 25, the L-shaped clamping block 25 can move towards the outside of the first detection disk 15 under the elastic force of the telescopic spring 22, and the telescopic touch plate 21 can slide simultaneously. Since the internal space where the first detection disk 15 is butted against the connection tube through the outer fixed tube 31 is in a sealed state, and the sliding of the telescopic touch plate 21 can apply negative pressure to this internal space, the piston rod 36 sliding inside the piston cylinder 35 can slide upwards and drive the sponge marking block 37 to move upwards, so as to mark the high-pressure oil pipe body 12, which is convenient for the operator to identify.

[0051] The sealing assembly 4 further includes a fixed disk 41 fixed to the outer wall of the propulsion frame 141. The inside of the fixed disk 41 is hollow, and the fixed disk 41 is located at the central position between the two sealing rings 42. A connecting cylinder 43 is fixedly arranged on the transmission pipe 26 inside the second detection disk 16. One end of the connecting cylinder 43 close to the fixed disk 41 is fixedly provided with a port disk 44. A blocking disk is fixedly arranged between the other end of the connecting cylinder 43 and the transmission pipe 26. And the port disk 44 rotates on the inner wall of the fixed disk 41. A plurality of communicating rods 45 slide on the port disk 44. Both ends of each communicating rod 45 penetrate from the inside of the fixed disk 41 to both sides of the outer wall of the fixed disk 41. Both ends of each communicating rod 45 extend into the two sealing rings 42 respectively. A plurality of arc-shaped chutes 441 matching the plurality of communicating rods 45 are formed on the port disk 44. A plurality of straight chutes 411 matching the plurality of communicating rods 45 are formed on the fixed disk 41. Two sealing push rods 46 are respectively fixed at both ends of each communicating rod 45. And each sealing push rod 46 slides on the inner wall of the sealing push rod 46. A sealing ring 47 is fixedly arranged on the arc-shaped outer wall of each sealing push rod 46. Each group of sealing push rods 46 is fixedly connected to the inner wall of the sealing ring 47.

[0052] The plurality of straight chutes 411 are distributed in a circular array on the fixed disk 41. The plurality of arc-shaped chutes 441 are distributed in a circular array on the port disk 44. A plurality of movable through slots matching the plurality of communicating rods 45 are formed on each sealing push rod 46.

[0053] An air inlet hole is formed in the sealing push rod 46 on the side close to the hydraulic rod 14, and an air inlet pipe is fixedly arranged inside the air inlet hole.

[0054] When detecting the high-pressure oil pipe body 12, by starting the two electric telescopic rods 112 and cooperating with the clamping assembly 11, the high-pressure oil pipe body 12 can be straightened. Then start the hydraulic rod 14. At the same time, with the cooperation of the smoothness detection assembly 2, when the transmission pipe 26 is pushed towards the transmission cylinder 34, the transmission pipe 26 can rotate. At this time, the connecting cylinder 43 fixedly connected to the transmission pipe 26 can be driven to rotate, and then the port disk 44 can be driven to rotate. Since the plurality of communicating rods 45 are slidably connected to the plurality of arc-shaped chutes 441 formed on the port disk 44, and the plurality of communicating rods 45 slide inside the plurality of straight chutes 411 formed on the fixed disk 41 at the same time, and at this time the fixed disk 41 is in a relatively static state, the plurality of communicating rods 45 can be made to slide towards the arc-shaped outer wall direction of the fixed disk 41 at the same time. Then drive the plurality of sealing push rods 46 respectively slidably connected to the two sealing rings 42 to push and squeeze the sealing ring 47, so that the sealing ring 47 is deformed, and the sealing ring 47 is closely attached to and clamped and sealed with the inner wall of the high-pressure oil pipe body 12, playing a sealing role. Furthermore, by docking the output end of the airtightness detector with the air inlet pipe, the airtightness of the high-pressure oil pipe body 12 can be directly detected.

[0055] Working principle and usage process of the present invention: When detecting the high-pressure oil pipe body 12, by starting two electric telescopic rods 112 and cooperating with the clamping assembly 11, the high-pressure oil pipe body 12 can be in a straightened state. Then, the hydraulic rod 14 is started. At the same time, with the cooperation of the smoothness detection assembly 2 and the marking assembly 3, assuming that the telescopic touch plate 21 on the first detection disk 15 contacts the convex block during this process, the transmission pipe 26 can rotate self-driven, and then the sponge marking block 37 can move upward under the negative pressure, so as to mark the high-pressure oil pipe body 12. At the same time, the displacement sensor 23 on the corresponding telescopic touch plate 21 can record the position of the convex block, and the displacement sensor 23 detects the moving distance and sends the data to the data processing terminal 13 through the data processing module. The self-rotation of the transmission pipe 26, with the cooperation of the sealing assembly 4 at the same time, enables multiple sealing push rods 46 to push the sealing ring 47, causing the sealing ring 47 to deform and making the sealing ring 47 closely adhere to the inner wall of the high-pressure oil pipe body 12 for clamping and sealing. Furthermore, by docking the output end of the airtightness detector with the air inlet pipe, the airtightness of the high-pressure oil pipe body 12 can be detected.

The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
