Description

Technical Field

[0001] This utility model relates to the field of brake pipe joint testing technology, and in particular to a testing device for hard brake pipe joints of automobiles. Background Technology

[0002] Automobile brakes, also known as vehicle braking, refer to a series of specialized devices that apply a certain force to certain parts of a vehicle (mainly the wheels) to forcibly brake it to a certain extent. The functions of the braking system are: to forcibly decelerate or even stop a moving vehicle according to the driver's requirements; to keep a stopped vehicle stable under various road conditions (including on slopes); and to maintain a stable speed for a vehicle traveling downhill.

[0003] In the existing technology, the brake pipe joint needs to be manually rotated to fix it in a designated position during inspection. Then, the surface and internal parts of the pipe are inspected by a testing instrument. It is necessary to check the precision of the external connecting thread teeth and whether the internal surface is flat. However, the traditional inspection method is not convenient for clamping and fixing, requires manual operation, is inefficient, and has a slow inspection speed, which affects the inspection efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for automotive brake pipe rigid pipe joints, which solves the problems of traditional testing methods being inconvenient to clamp and fix, requiring manual operation, resulting in low efficiency and slow testing speed, thus affecting testing efficiency.

[0005] To achieve the above objectives, a testing device for automotive brake pipe hard connectors is provided, comprising: a testing platform, a first fixed plate fixedly connected to one side of the top of the testing platform, a first threaded rod connected to the interior of the first fixed plate after rotation, a movable plate threadedly connected to the upper middle part of the first threaded rod, a detector fixedly connected to one side of the movable plate and the top of the first fixed plate, a second fixed plate fixedly connected to the other side of the top of the testing platform, an upper arc-shaped clamping plate provided at the top of the second fixed plate, a second threaded rod threadedly connected to both ends of the interior of the upper arc-shaped clamping plate, a small motor fixedly connected to the bottom end of the second threaded rod, the small motor being fixedly connected to the second fixed plate, a turntable rotatably connected to the interior center of the testing platform, and a concave frame fixedly connected to the top of the turntable.

[0006] As a preferred technical solution of this utility model, a second motor is fixedly connected to the top of the inner part of the concave frame, and a bidirectional screw is fixedly connected to the drive end of the second motor.

[0007] As a preferred technical solution of this utility model, threaded blocks are threadedly connected to both sides of the middle part of the bidirectional screw.

[0008] As a preferred technical solution of this utility model, a rotating rod is rotatably connected to one side of the threaded block, and a clamping plate is rotatably connected to one end of the rotating rod.

[0009] As a preferred technical solution of this utility model, both sides of the clamping plate are fixedly connected with sliding rods, and the sliding rods are slidably engaged with the outer wall of the concave frame.

[0010] As a preferred technical solution of this utility model, a fixing frame is fixedly connected to the bottom center of the testing platform.

[0011] As a preferred technical solution of this utility model, a drive motor is fixedly connected to the middle of the bottom end of the fixed frame, and the drive end of the drive motor is fixedly connected to the turntable.

[0012] As a preferred technical solution of this utility model, a brake rigid tube is clamped between the second fixing plate and the upper arc-shaped clamping plate.

[0013] The above-mentioned solution has the following beneficial effects: This utility model comprises a small motor, a second threaded rod, an upper arc-shaped clamping plate, and a first fixing plate. Driven by the small motor, the second threaded rod rotates, engaging with the upper arc-shaped clamping plate via a threaded connection. This allows for threaded movement of the upper arc-shaped clamping plate, which is then pressed down to clamp the brake tube. After clamping, the detector at the top of the first fixing plate can easily inspect the interior of the brake tube. This structure achieves automated clamping, improving ease of use and solving the problem of the time-consuming and labor-intensive traditional manual bolt clamping method.

[0014] This utility model comprises a first threaded rod, a movable plate, a concave frame, and a clamping plate. Driven by a second motor, the bidirectional screw rotates, causing the clamping plate to expand outward. The clamping plate then clamps and holds the inner wall of the brake tube. A servo motor drives the first threaded rod, causing the detector on one side of the movable plate to move up and down, and the outer side of the concave frame to move the brake tube, thus detecting the surface of the brake tube. Simultaneously, the drive motor starts, causing the turntable and the concave frame to rotate, facilitating the detection of the entire circumferential surface with the detector.

[0019] Reference Figure 1-4This utility model discloses a testing device for automotive brake hose hard pipe joints, comprising: a testing platform 1, a first fixed plate 3 fixedly connected to one side of the top of the testing platform 1, a first threaded rod 4 connected to the inside of the first fixed plate 3 after rotation, and a servo motor driving the first threaded rod 4. A moving plate 13 is threadedly engaged with the first threaded rod 4 to achieve threaded movement, thereby raising and lowering a detector 2 on one side of the moving plate 13. The moving plate 13 is threadedly connected to the upper middle part of the first threaded rod 4, and detectors 2 are fixedly connected to one side of the moving plate 13 and the top of the first fixed plate 3. The detector 2 at the top of the first fixed plate 3 inspects the inside of the brake hose 6 to prevent damage to the inner wall of the brake hose 6. A second fixed plate 2 is fixedly connected to the other side of the top of the testing platform 1. The fixed plate 9 is used to fix the brake hard tube 6 to the top of the second fixed plate 9 and the inner side of the upper arc-shaped clamping plate 8. The upper arc-shaped clamping plate 8 is provided at the top of the second fixed plate 9. The upper arc-shaped clamping plate 8 can move threadedly. Pressing down the upper arc-shaped clamping plate 8 can clamp the brake hard tube 6. The two ends of the upper arc-shaped clamping plate 8 are threadedly connected to the second threaded rod 12. The bottom end of the second threaded rod 12 is fixedly connected to the small motor 7. The small motor 7 drives the second threaded rod 12 to rotate. After rotation, it engages with the upper arc-shaped clamping plate 8 threadedly. The small motor 7 is fixedly connected to the second fixed plate 9. The turntable 14 is rotatably connected to the middle of the inside of the testing table 1. The top of the turntable 14 is fixedly connected to the concave frame 5. The brake hard tube 6 is sleeved on the outside of the concave frame 5.

[0020] A second motor 15 is fixedly connected to the top of the concave frame 5. Driven by the second motor 15, the bidirectional screw 19 rotates. After rotation, it engages with the threaded block 17, thus achieving threaded movement. The drive end of the second motor 15 is fixedly connected to the bidirectional screw 19. Threaded blocks 17 are threadedly connected to both sides of the middle of the bidirectional screw 19. A rotating rod is rotatably connected to one side of the threaded block 17. A clamping plate 16 is rotatably connected to one end of the rotating rod. This causes the threaded block 17 to move closer to the center. The support of the rotating rod after it moves closer allows the clamping plate 16 to expand outwards. The holding plate 16 can clamp the inner wall of the brake hard tube 6. The two sides of the holding plate 16 are fixedly connected to the sliding rods 18, which slide in cooperation with the outer wall of the concave frame 5. The bottom center of the detection table 1 is fixedly connected to the fixing frame 11, and the bottom center of the fixing frame 11 is fixedly connected to the drive motor 10. When the drive motor 10 is started, it drives the turntable 14 and the concave frame 5 to rotate, which facilitates the detection of the entire circumferential surface with the detector 2. The drive end of the drive motor 10 is fixedly connected to the turntable 14. The brake hard tube 6 is clamped between the second fixing plate 9 and the upper arc-shaped clamping plate 8.

[0021] Working principle: In use, the brake rigid tube 6 is first fixed to the top of the second fixing plate 9 and the inner side of the upper arc-shaped clamping plate 8. This is then driven by a small motor 7, which rotates the second threaded rod 12. This rotation engages with the upper arc-shaped clamping plate 8, allowing for threaded movement and downward pressure. This pressure clamps the brake rigid tube 6, facilitating inspection of the interior of the brake rigid tube 6 by the detector 2 at the top of the first fixing plate 3, preventing damage to the inner wall of the brake rigid tube 6. Simultaneously, the brake rigid tube 6 can be fitted onto the outside of the concave frame 5. Driven by the second motor 15, the bidirectional screw 19 rotates. After the movement, the screw engages with the threaded block 17, enabling threaded movement. The threaded block 17 is moved closer to the center, and the support of the rotating rod expands the clamping plate 16 outward. The clamping plate 16 clamps the inner wall of the brake tube 6. At this time, the servo motor drives the first threaded rod 4, and the moving plate 13 engages with the first threaded rod 4, enabling threaded movement. The detector 2 on one side of the moving plate 13 moves up and down, and the outer brake tube 6 of the concave frame 5 moves up and down, enabling detection of the surface of the brake tube 6. At the same time, the drive motor 10 starts and drives the turntable 14 and the concave frame 5 to rotate, which facilitates the detection of the entire circumferential surface with the detector 2.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
