[0002] With the continuous development of society and the continuous progress of technology, the related technologies for guide shaft inspection and fixing are also constantly improving. After the guide shafts of subway, high-speed rail and other rail vehicles are produced, they need to be strictly inspected to confirm whether they meet the factory standards. A laser diameter gauge is installed on the inspection and fixing device. The laser diameter gauge can detect the shaft diameter. The inspection and fixing device can be used to inspect and process the guide shaft.

[0003] The current devices for fixing and inspecting guide shafts are not convenient for fixing guide shafts of different diameters, which makes it inconvenient to inspect guide shafts of different diameters in the future, thus hindering the use of the inspection and fixing devices. Utility Model Content

Therefore, a rail transit guide shaft detection and fixing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rail transit guide shaft detection and fixing device includes a support frame, a detection frame fixedly connected to the support frame, a laser diameter measuring instrument mounted on the detection frame, a reciprocating screw rotatably connected to the support frame, a slider threadedly connected to the reciprocating screw, and a mounting frame provided below the slider. The mounting frame has two fixing rings, one of which is fixedly connected to the mounting frame, and the other is slidably connected to the mounting frame. Each fixing ring has multiple T-shaped clamps slidably connected to it. Each fixing ring also has a moving component, which includes multiple sliding rods slidably mounted on the fixing ring. Each sliding rod is connected to a corresponding T-shaped clamp via a first hinge rod and is connected by an annular plate. The mounting frame also has a driving component.

[0006] Preferably, the drive assembly includes an electric push rod fixedly mounted on the mounting bracket. The drive end of the electric push rod is fixedly connected to a limit frame. Two moving blocks are provided on the limit frame. One of the moving blocks is fixedly connected to the limit frame, and the other moving block is slidably connected to the limit frame. The two moving blocks are respectively connected to the corresponding annular plate through two second hinge rods.

[0007] Preferably, the limiting frame has a T-shaped groove for the moving block to slide back and forth, and a rectangular rod is fixedly connected inside the mounting frame, wherein one of the fixing rings is fixedly connected to the rectangular rod, and the other fixing ring is slidably connected to the rectangular rod.

[0008] Preferably, an electric telescopic rod is fixedly connected to the slider, and a concave frame is fixedly connected to the telescopic end of the electric telescopic rod. The mounting frame and the concave frame are rotatably connected.

[0009] Preferably, servo motors are fixedly connected to both the support frame and the concave frame.

Each servo motor is equipped with an electromagnetic brake at its drive end.

[0010] Preferably, a crossbar is fixedly connected to the support frame, and the slider and the crossbar are slidably connected.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Through the cooperation of the moving component and the driving component, multiple T-shaped clamps can move radially, which can stably clamp rail transit guide shafts of different diameters, solving the problem of inconvenience in fixing guide shafts of different diameters and greatly expanding the applicability of the device.

[0012] By utilizing the transmission and cooperation of reciprocating lead screw and slider and the drive of servo motor, the guide shaft can move and rotate automatically. Combined with laser diameter measuring instrument, it can complete multi-directional and automated detection without the need for frequent manual adjustments, which significantly improves detection efficiency and reduces the intensity of manual operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The laser diameter measuring instrument is used to detect the diameter of the guide shaft. A reciprocating screw 3 is rotatably connected to the support frame 1, and a slider 5 is threadedly connected to the reciprocating screw 3. A mounting frame 4 is provided below the slider 5. The mounting frame 4 is provided with two fixing rings 8, one of which is fixedly connected to the mounting frame 4, and the other is slidably connected to the mounting frame 4. Each fixing ring 8 has... The sliding connection has multiple T-shaped clamps 15. Each fixed ring 8 is equipped with a moving component. The moving component includes multiple slide rods 16 slidably mounted on the fixed ring 8. The multiple slide rods 16 are connected to the corresponding T-shaped clamps 4 through first hinge rods 17. The two ends of each first hinge rod 17 are respectively hinged to the corresponding slide rod 16 and the corresponding T-shaped clamp 15. The T-shaped clamps 15 are arranged radially along the fixed ring 8 and are used to clamp the guide shaft. The multiple slide rods 16 are connected through an annular plate 9. Each slide rod 16 is fixedly connected to the annular plate 9. The annular plate 9 can drive the multiple slide rods 16 to slide synchronously. The mounting frame 4 is equipped with a driving component.

[0018] The drive assembly includes an electric push rod 14 fixedly mounted on the mounting frame 4. The drive end of the electric push rod 14 is fixedly connected to a limiting frame 13. Two moving blocks 11 are provided on the limiting frame 13. One moving block 11 is fixedly connected to the limiting frame 13, and the other moving block 11 is slidably connected to the limiting frame 13. The two moving blocks 11 are respectively connected to the corresponding annular plate 9 through two second hinge rods 10. The two ends of each hinge rod 10 are respectively hinged to the corresponding moving block 11 and the corresponding annular plate 9. The limiting frame 13 is provided with a T-shaped groove for the moving block 11 to slide back and forth. A rectangular rod 18 is fixedly connected inside the mounting frame 4. One fixed ring 8 is fixedly connected to the rectangular rod 18, and the other fixed ring 8 is slidably connected to the rectangular rod 18. The fixed ring 8 fixed to the mounting frame 4 is fixedly connected to the rectangular rod 18, and the fixed ring 8 sliding to the mounting frame 4 is slidably connected to the rectangular rod 18. The rectangular rod 18 provides guidance for the sliding fixed ring 8.

[0019] An electric telescopic rod 6 is fixedly connected to the slider 5. A concave frame 7 is fixedly connected to the telescopic end of the electric telescopic rod 6. The mounting frame 4 and the concave frame 7 are rotatably connected. Servo motors 19 are fixedly connected to both the support frame 1 and the concave frame 7. The drive ends of the two servo motors 19 are fixedly connected to the reciprocating lead screw 3 and the mounting frame 4, respectively. Each servo motor 19 is equipped with an electromagnetic brake at its drive end. The electromagnetic brake is used to lock the position when the servo motor stops to ensure structural stability. A crossbar 2 is fixedly connected to the support frame 1. The slider 5 and the crossbar 2 are slidably connected. The crossbar 2 guides the slider 5 to ensure that the slider 5 moves stably along the axial direction of the reciprocating lead screw 3.

[0020] In this invention, the guide shaft is placed in the area between two fixed rings 8 and between multiple T-shaped clamps 4. The guide shaft is in contact with the surfaces of the two lower T-shaped clamps 4. When the electric push rod 14 is activated, its driving end pushes the limiting frame 13 downward. The limiting frame 13 drives two annular plates 9 to move simultaneously along the reciprocating screw 3 through two second hinge rods 10. When the annular plates 9 move, they drive multiple sliding rods 16 to slide on the fixed rings 8. The sliding rods 16 push the T-shaped clamps 15 to move radially along the fixed rings 8 to the guide shaft through the first hinge rod 17 until the multiple T-shaped clamps 15 clamp and fix the guide shaft. During this process, the fixed rings 8 do not slide relative to the mounting frame 4. Since the moving block 11 can slide in the T-shaped groove of the limiting frame 13, this structure can adapt to guide shafts of different lengths and achieve clamping of guide shafts of different specifications.

[0021] The servo motor 19 connected to the reciprocating lead screw 3 is started, which drives the reciprocating lead screw 3 to rotate, thereby driving the slider 5 to slide along the crossbar 2, so that the mounting frame 4 and the fixed guide shaft move axially along the reciprocating lead screw 3. The guide shaft passes through the laser diameter measuring instrument on the detection frame 12 to complete the diameter detection.

[0022] The height of the mounting frame 4 can be adjusted by the electric telescopic rod 6 to adapt to different detection height requirements; starting the servo motor 19 connected to the mounting frame 4 can drive the mounting frame 4 to rotate, which in turn drives the guide shaft to rotate, realizing the detection of different circumferential positions of the guide shaft, and also facilitating the unloading of the guide shaft after detection.
