[0022] See also Figure 1 - Figure 4The utility model provides a technical solution: a pneumatic plug-in device for automobile brake hose, comprising a device body 1, a U-shaped frame 2 is fixedly connected to the top of the device body 1, a positioning assembly 4 is arranged on the inner side of the U-shaped frame 2, a guide rail assembly 5 is arranged inside the device body 1, a joint assembly 6 is detachably connected to the top of the guide rail assembly 5, a protective box 3 is fixedly connected to the top of the U-shaped frame 2, the positioning assembly 4 comprises an electric cylinder 41, one of the electric cylinders 41 is fixedly connected to the inside of the protective box 3, and the bottom end of the electric cylinder 41 extends to the inside of the U-shaped frame 2, another electric cylinder 41 is fixedly connected to the inside of the device body 1, and the top end of the electric cylinder 41 extends to the inside of the U-shaped frame 2, and the bottom end of one of the electric cylinders 41 and the inside of the U-shaped frame 2 is fixedly connected to a first clamping hose. The top of the other electric cylinder 41 is fixedly connected with a second hose clamping fixture 43 located on the inner side of the U-shaped frame 2. The first hose clamping fixture 42 and the second hose clamping fixture 43 are both provided with arc grooves 44 inside. First, the hose is placed between the first hose clamping fixture 42 and the second hose clamping fixture 43, and the two electric cylinders 41 are started. The first hose clamping fixture 42 and the second hose clamping fixture 43 are driven by the electric cylinders 41 to fit together and approach each other, so that the first hose clamping fixture 42 and the second hose clamping fixture 43 clamp the hose. At this time, the arc grooves 44 in the first hose clamping fixture 42 and the second hose clamping fixture 43 wrap the hose, and chamfers are provided inside, so that the hose will not be clamped during work, which protects the hose and reduces damage to the hose.

[0023] Furthermore, the guide rail assembly 5 includes a movable groove 51, and two movable grooves 51 are both arranged inside the device body 1. Two gears 53 are rotatably connected inside the device body 1, and the two gears 53 are fixedly connected by a connecting shaft. The outside of the device body 1 is fixedly connected with a driving motor 52, and the output shaft of the driving motor 52 extends to the inside of the device body 1 and is fixedly connected to one of the gears 53. The outsides of the two gears 53 are meshed with racks 54, and the tops of the two racks 54 are fixedly connected with connecting members 55, and the tops of the two connecting members 55 are fixedly connected with fixing plates 56, and a mounting plate 57 is fixedly connected between the two fixing plates 56.

Use fixing bolts 62 to install it on the mounting plate 57, then place the joint in the joint groove 64, start the driving motor 52, and drive one of the gears 53 to rotate through the driving motor 52. When one of the gears 53 rotates, the other gear 53 is driven to rotate through the connecting shaft. When the two gears 53 rotate at the same time, the rack 54 meshing therewith will be driven to move horizontally in the movable groove 51, so that the joint in the joint groove 64 moves toward the direction of the hose, slides to a specified distance, and the sleeve is completely inserted into the hose. Thus, the joint hose is assembled by applying pressure through the electric cylinder 41, which reduces manpower and improves efficiency. The guide rail assembly 5 ensures that the sleeve is accurately inserted into the hose, thereby ensuring the concentricity of the hose and the joint, and reducing the risk of the hose being worn, making the insertion of the tube simple and easy.

At this time, the arc groove 44 in the first hose clamping fixture 42 and the second hose clamping fixture 43 wraps the hose, and the inside is chamfered, so that the hose will not be clamped during work, which protects the hose and reduces damage to the hose. Subsequently, the clamping joint fixture 63 is installed on the mounting plate 57 through the disassembly plate 61 using the fixing bolts 62, and then the joint is placed in the joint groove 64, and the drive motor 52 is started to drive one of the gears 53 to rotate. When one of the gears 53 is driven to rotate, When the gear 53 rotates, it drives another gear 53 to rotate through the connecting shaft. When the two gears 53 rotate at the same time, it drives the meshing rack 54 to move horizontally in the movable groove 51, so that the joint in the joint groove 64 moves toward the direction of the hose and slides to the specified distance. The sleeve is completely inserted into the hose. Thus, the joint hose is assembled by applying pressure through the electric cylinder 41, which reduces manpower and improves efficiency. The guide rail assembly 5 ensures that the sleeve is accurately inserted into the hose, thereby ensuring the concentricity of the hose and the joint and reducing the risk of hose wear, making insertion simple and easy. The disassembly plate 61 can replace the tooling for different products. The product is accurately clamped by the gap between the first hose clamping tooling 42 and the second hose clamping tooling 43, and the chamfer ensures that the product will not be damaged during the work process, which perfectly solves the problem of time-consuming and labor-intensive insertion.
