The DC brushless hydraulic pump includes a motor and an oil pump, the motor being driven by a mobile power supply. A pipe positioning module is provided on the surface of the chassis, and flaring modules and clamping modules corresponding to the pipe positioning modules are provided at different positions on the surface of the chassis. The flaring modules and clamping modules are driven by corresponding hydraulic cylinders. The chassis of this utility model is a small integrated structure, small in size and light in weight, easy to move and carry, and suitable for processing in different occasions. The motor can be driven by a mobile power supply, and the motor drives the oil pump to deliver hydraulic oil to the hydraulic cylinders. The solenoid valve can control the opening and closing of the pipeline. The hydraulic cylinders, together with the flaring modules and clamping modules, can realize the clamping and flaring of pipes.

[0005] Preferably, the hydraulic cylinder is equipped with a first piston rod extending longitudinally and a second piston rod extending laterally, respectively. The first and second piston rods are respectively connected to the clamping module and the flaring module. The motor can be driven by a mobile power supply, which in turn drives the oil pump to deliver hydraulic oil to the hydraulic cylinder. The solenoid valve controls the opening and closing of the pipeline. The hydraulic cylinder drives the first and second piston rods to reciprocate. The first piston rod cooperates with the clamping module to clamp and position the pipe fitting, and the second piston rod cooperates with the flaring module to flare the pipe fitting.

[0006] Preferably, the pipe fitting positioning module includes a flared positioning block fixed to the surface of the chassis, the flared positioning block having a hollow structure.

[0009] Preferably, the limiting baffle has a window at its end, and the flaring positioning block has a fine-tuning groove corresponding to the limiting baffle on its outer side. The fine-tuning groove is used to accommodate the adjustment of the limiting baffle. In the initial state, the end of the pipe will abut against the tail end of the limiting baffle. After the machine box is opened, the limiting baffle moves with the sliding fixture, and the flaring process can be performed through the window.

[0010] Preferably, the clamp module further includes a fine-tuning scale slidably mounted on the surface of the fine-tuning module, the fine-tuning scale abutting against the surface of the limiting baffle. During adjustment, the fine-tuning scale can display the fine-tuning distance.

One end of the flaring slider is fixedly connected to a second piston rod, and the other end of the flaring slider is provided with a detachable flaring mold.
