A fully automatic detection device for motor fuel injection pipe

Abstract

This utility model belongs to the technical field of testing devices, and relates to a fully automatic testing device for motor fuel injection pipes. It includes a housing, inside which a first rotating ring and a second rotating ring are rotatably arranged. The same pipe is mounted on both the first and second rotating rings. Each of the first and second rotating rings is equipped with a clamping assembly for fixing the pipe. A horizontal threaded rod is rotatably arranged at the top of the housing, and a slide is threaded onto the threaded rod. The slide is horizontally slidably connected to the inside of the housing. A testing assembly is located at the bottom of the slide. A driving assembly is located on one side of the housing, driving the threaded rod and the second rotating ring to rotate alternately. The advantage is that when testing the pipe fixed on the first and second rotating rings, the motor drives the connecting shaft to rotate, causing the connecting shaft to drive the second rotating ring to rotate, thus rotating the pipe and the first rotating ring. Combined with the horizontal movement of the slide, this allows the flaw detector to inspect the entire pipe, making the inspection more thorough.

Technical Field

[0001] This utility model belongs to the technical field of testing devices, and relates to a fully automatic testing device for motor fuel injection pipes. Background Technology

[0002] An electric motor oil injection pipe specifically refers to a metal pipe assembly integrated into the motor cooling structure. Its core function is to deliver cooling oil to the critical heat-generating parts of the motor for directional spray cooling. After production, the electric motor oil injection pipe needs to undergo a comprehensive evaluation of its sealing performance, structural integrity, and material defects to ensure its reliability; therefore, testing equipment is required.

[0003] A fuel injection pipe inspection tool for an engine disclosed in Chinese patent CN215894486U includes a base, an inverted U-shaped plate, a fuel injection pipe body, an inspection mechanism, and two sets of clamping assemblies distributed at equal distances. The inverted U-shaped plate is welded to the top outer wall of the base, and the fuel injection pipe body is placed on the top of the base. The two sets of clamping assemblies distributed at equal distances are respectively arranged on both sides of the inverted U-shaped plate, and the inspection mechanism is located on the top of the inverted U-shaped plate.

[0004] The inspection tool is used to inspect by moving the flaw detector horizontally. However, the fuel injection pipe is fixed during the inspection, which means that the flaw detector can only inspect one position on the fuel injection pipe, resulting in an incomplete inspection.

[0005] To solve the above problems, this utility model proposes a fully automatic detection device for motor fuel injection pipe. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a fully automatic detection device for motor fuel injection pipes.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a box body, and the box body is rotatably provided with a first rotating ring and a second rotating ring. The same tube body is provided on the first rotating ring and the second rotating ring, and a clamping component for fixing the tube body is provided on both the first rotating ring and the second rotating ring.

[0008] A horizontal threaded rod is rotatably installed at the top of the box, and a slide is threadedly fitted on the threaded rod. The slide is horizontally slidably connected to the inside of the box, and a detection component is installed at the bottom of the slide.

[0009] A drive assembly is provided on one side of the housing, which drives the threaded rod and the second rotating ring to rotate alternately.

[0010] Furthermore, the first rotating ring rotates through one side of the housing, and the second rotating ring rotates through one side of the housing corresponding to the first rotating ring. The first rotating ring and the second rotating ring are arranged coaxially.

[0011] The interior of the first rotating ring is through, and the end of the second rotating ring away from the first rotating ring is sealed. The tube passes through the first rotating ring, and one end of the tube extends into the second rotating ring and abuts against the sealing surface inside the second rotating ring.

[0012] Furthermore, the clamping assembly includes a plurality of first electric push rods. The plurality of first electric push rods in the clamping assembly located on the first rotating ring are uniformly and fixedly connected to the side of the first rotating ring. The plurality of first electric push rods in the clamping assembly located on the second rotating ring are uniformly and fixedly connected to the side of the second rotating ring. The telescopic end of each first electric push rod faces the tube body.

[0013] Each of the first electric push rods has a clamping plate fixedly connected to its telescopic end. The side of the clamping plate closest to the tube body is arc-shaped, and the arc-shaped surface of each clamping plate movably abuts against the outer surface of the tube body.

[0014] Furthermore, a clearance groove is provided on the inner wall of the first rotating ring and the second rotating ring at each first electric push rod, and the clamping plate is movably engaged in the corresponding clearance groove.

[0015] Furthermore, one end of the threaded rod is rotatably connected to a side of the housing where a first rotating ring is provided, and the other end of the threaded rod rotatably passes through a side of the housing where a second rotating ring is provided. The end of the threaded rod extending outside the housing is fixedly fitted with a first gear.

[0016] Furthermore, a guide rod is fixedly connected inside the housing, the guide rod is parallel to the threaded rod, and one end of the slide is slidably sleeved on the guide rod.

[0017] Furthermore, the drive assembly includes a motor, an L-shaped support frame is fixedly connected to one side of the housing, the motor is fixedly connected to the support frame, the end of the motor's output shaft is rotatably connected to the side of the housing, and an incomplete gear is fixedly sleeved on the motor's output shaft;

[0018] A rotating shaft is rotatably connected to one side of the housing, and a second gear is fixedly sleeved on the rotating shaft. The teeth on the incomplete gear mesh with the first gear and the second gear.

[0019] A belt drive is provided between the rotating shaft and the second rotating ring.

[0020] Furthermore, the belt drive component includes a belt, and a connecting shaft is coaxially fixedly connected to the side of the second rotating ring away from the first rotating ring. Pulleys are fixedly sleeved on both the connecting shaft and the rotating shaft, and the belt drive is sleeved on the two pulleys.

[0021] Furthermore, the detection assembly includes a flaw detector, a second electric push rod is fixedly installed at the bottom of the carriage, a mounting plate is fixedly connected to the bottom of the telescopic end of the second electric push rod, the flaw detector is fixedly installed on the top of the mounting plate, and the probe of the flaw detector is fixedly connected to the bottom of the mounting plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When the fully automatic motor-driven fuel injection pipe inspection device inspects the pipe body fixed on the first and second rotating rings, the motor drives the connecting shaft to rotate, which in turn drives the second rotating ring to rotate, causing the pipe body and the first rotating ring to rotate. In conjunction with the horizontal movement of the slide, the flaw detector can inspect the entire pipe body, making the inspection more comprehensive.

[0024] 2. The fully automatic detection device for the motor-driven fuel injection pipe is equipped with an incomplete gear. When the incomplete gear meshes with the second gear, it drives the pipe body to rotate. When the incomplete gear meshes with the first gear, it drives the slide to move horizontally. This causes the pipe body and the slide to move alternately, so that the flaw detector can detect the rotating pipe body. When the flaw detector moves, the pipe body no longer rotates. Therefore, it is not necessary to use a separate drive source to drive the flaw detector and the pipe body, thus reducing production costs. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A fully automatic detection device for motor fuel injection pipes includes a housing 1. Inside the housing 1, a first rotating ring 3 and a second rotating ring 6 are rotatably arranged. The same pipe body 2 is arranged on the first rotating ring 3 and the second rotating ring 6. The pipe body 2 is the pipe body of the motor fuel injection pipe.

[0032] The first rotating ring 3 rotates through one side of the housing 1, and the second rotating ring 6 rotates through the opposite side of the housing 1. The first rotating ring 3 and the second rotating ring 6 are arranged coaxially.

[0033] Annular grooves are formed on the outer surfaces of the middle parts of the first rotating ring 3 and the second rotating ring 6, and through holes that fit the grooves are formed on both sides of the housing 1. The first rotating ring 3 and the second rotating ring 6 are positioned on the housing 1 by the cooperation of the through holes and the grooves.

[0034] The interior of the first rotating ring 3 is through-hole, and the end of the second rotating ring 6 away from the first rotating ring 3 is sealed. The tube 2 passes through the first rotating ring 3, and one end of the tube 2 extends into the second rotating ring 6 and abuts against the sealing surface inside the second rotating ring 6. This facilitates the movement of the tube 2 through the first rotating ring 3.

[0035] Both the first rotating ring 3 and the second rotating ring 6 are equipped with clamping components for fixing the tube body 2.

[0036] The clamping assembly includes several first electric push rods 4. The several first electric push rods 4 in the clamping assembly located on the first rotating ring 3 are uniformly and fixedly connected to the inner side of the first rotating ring 3; the several first electric push rods 4 in the clamping assembly located on the second rotating ring 6 are uniformly and fixedly connected to the inner side of the second rotating ring 6. The telescopic end of each first electric push rod 4 faces the tube body 2, allowing the telescopic end of each first electric push rod 4 to move towards the tube body 2.

[0037] Each first electric push rod 4 has a clamping plate 5 fixedly connected to its telescopic end. The side of the clamping plate 5 closest to the tube body 2 is arc-shaped. The arc-shaped surface of each clamping plate 5 movably abuts against the outer surface of the tube body 2. By pushing the clamping plates 5 with the first electric push rod 4, several clamping plates 5 cooperate to clamp the tube body 2. A rubber layer can be provided on the arc-shaped surface of the clamping plate 5 so that the rubber layer contacts the tube body 2 when clamping, avoiding excessive clamping force that could damage the tube body 2.

[0038] On the inner walls of the first rotating ring 3 and the second rotating ring 6, there are relief grooves at each of the first electric push rods 4, and the clamping plate 5 is movably engaged in the corresponding relief groove. By moving the clamping plate 5 into the relief groove, the tube 2 can be moved onto the first rotating ring 3 and the second rotating ring 6.

[0039] A horizontal threaded rod 11 is rotatably mounted on the top of the housing 1.

[0040] One end of the threaded rod 11 is rotatably connected to a side of the housing 1 where the first rotating ring 3 is located, and the other end of the threaded rod 11 rotatably passes through a side of the housing 1 where the second rotating ring 6 is located. A first gear 10 is fixedly fitted onto the end of the threaded rod 11 that extends outside the housing 1. This allows the threaded rod 11 to be arranged along the length of the tube 2.

[0041] A slide 13 is threaded onto the threaded rod 11, and the slide 13 is horizontally slidably connected to the inside of the housing 1. When the threaded rod 11 rotates, it drives the slide 13 to move horizontally.

[0042] A guide rod 12 is fixedly connected inside the housing 1, and the guide rod 12 is parallel to the threaded rod 11. One end of the slide 13 is slidably sleeved on the guide rod 12. The guide rod 12 positions the threaded rod 11.

[0043] A detection component is provided at the bottom of the carriage 13.

[0044] The inspection components include a flaw detector 20. A second electric push rod 14 is fixedly installed at the bottom of the carriage 13, and the second electric push rod 14 is arranged vertically.

[0045] The bottom of the telescopic end of the second electric push rod 14 is fixedly connected to a mounting plate 15, which allows the second electric push rod 14 to push the mounting plate 15 up and down. The flaw detector 20 is fixedly installed on the top of the mounting plate 15, and the probe of the flaw detector 20 is fixedly connected to the bottom of the mounting plate 15.

[0046] The flaw detector 20 is an industrial non-destructive testing device used to detect microscopic defects (such as cracks, pores, inclusions, etc.) inside or on the surface of a workpiece without damaging the material, thereby ensuring safe equipment operation and product quality. The flaw detector 20 is an existing product and is also used in patent CN215894486U mentioned in the background art, therefore it can be used to inspect the pipe body 2.

[0047] A drive assembly is provided on one side of the housing 1, which drives the threaded rod 11 and the second rotating ring 6 to rotate alternately.

[0048] The drive assembly includes a motor 8. An L-shaped support frame 7 is fixedly connected to one side of the housing 1, and the motor 8 is fixedly connected to the support frame 7. The end of the output shaft of the motor 8 is rotatably connected to the side of the housing 1. An incomplete gear 9 is fixedly fitted on the output shaft of the motor 8. The motor 8 drives the incomplete gear 9 to rotate.

[0049] A rotating shaft 18 is rotatably connected to one side of the housing 1, and a second gear 16 is fixedly mounted on the rotating shaft 18. The teeth on the incomplete gear 9 mesh with the first gear 10 and the second gear 16. When the incomplete gear 9 meshes with the first gear 10, the teeth on the incomplete gear 9 do not contact the second gear 16, so that the incomplete gear 9 can only drive one of the first gear 10 and the second gear 16 to rotate at a time.

[0050] A belt drive is provided between the rotating shaft 18 and the second rotating ring 6.

[0051] The belt drive includes a belt 17. A connecting shaft 19 is coaxially fixedly connected to the side of the second rotating ring 6 away from the first rotating ring 3. Pulleys are fixedly sleeved on both the connecting shaft 19 and the rotating shaft 18. The belt 17 is driven to rotate synchronously on the two pulleys. The belt 17 drives the connecting shaft 19 and the rotating shaft 18 to rotate synchronously.

[0052] Working principle:

[0053] In use, move the tube body 2 to one side of the first rotating ring 3. Insert one end of the tube body 2 into the first rotating ring 3, so that one end of the tube body 2 moves into the second rotating ring 6. Continue until the end of the tube body 2 abuts against the sealing surface inside the second rotating ring 6. At this time, the tube body 2 is located between several clamping plates 5 on the first rotating ring 3 and the second rotating ring 6.

[0054] Start the first electric push rod 4, so that the telescopic end of the first electric push rod 4 pushes the clamping plate 5 to move towards the tube body 2 until several clamping plates 5 are all in contact with the outer surface of the tube body 2, and clamp and fix the tube body 2.

[0055] The second electric push rod 14 is activated, and its telescopic end pushes the mounting plate 15 downward, causing the flaw detector 20 and its probe to move downward. This continues until the probe of the flaw detector 20 reaches the top of the pipe body 2, allowing the probe to inspect the pipe body 2.

[0056] Start motor 8, which drives incomplete gear 9 to rotate. The teeth on incomplete gear 9 drive second gear 16 to rotate, while first gear 10 does not rotate.

[0057] The second gear 16 drives the rotating shaft 18 to rotate, and the rotating shaft 18 drives the connecting shaft 19 to rotate via the belt 17, causing the second rotating ring 6 to rotate. The second rotating ring 6 drives the tube body 2 and the first rotating ring 3 to rotate, causing the tube body 2 to rotate at the bottom of the probe, and the probe detects the rotating tube body 2.

[0058] After the tube body 2 rotates one revolution, the teeth on the incomplete gear 9 disengage from the second gear 16, and the tube body 2 stops rotating. Then, the incomplete gear 9 drives the first gear 10 to rotate, causing the threaded rod 11 to rotate. The threaded rod 11 drives the slide 13 to move horizontally, and the slide 13 slides on the guide rod 12.

[0059] The slide 13 drives the second electric push rod 14, the mounting plate 15, and the flaw detector 20 to move, so that the probe moves on the tube body 2.

[0060] Then, the teeth on the incomplete gear 9 disengage from the first gear 10, causing the flaw detector 20 to stop moving. The incomplete gear 9 then continues to drive the tube body 2 to rotate, thereby enabling the probe to detect the outer surface of the next location on the tube body 2, thus achieving automatic detection of the tube body 2.

[0061] After the tube body 2 is inspected, the first electric push rod 4 is activated, which pulls the clamping plate 5 to move away from the tube body 2. Because the tube body 2 has weight, it will move downward under the action of gravity, thus remaining on the clamping plate 5 below.

[0062] The clamps 5 located on the top and sides will leave the tube body 2, and then the tube body 2 will be removed from the first rotating ring 3.

[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
