Embodiment 1
[0025] Such as Figure 1~2 As a preferred embodiment, the motor 1 of the oil and gas pipeline desilting device is installed on the motor base 7, the motor 1 is connected to the rotating shaft 2, the rotation of the motor 1 drives the rotating shaft 2 to rotate, and the rotating shaft 2 is fixedly connected to an adjustable chuck 3, which can be adjusted The chuck 3 and the rotating shaft 2 are coaxial, and a plurality of connecting claws 4 are arranged on the end face of the adjustable chuck 3. The adjustable chuck 3 and the connecting claws 4 are similar to the three-jaw adjustable chuck on the machine tool. The radial position of the connecting claws 4 on the end surface of the adjustable chuck 3 can be adjusted to realize "opening" and "shrinking" of multiple connecting claws 4 in the radial direction. For example, by setting the connecting claw 4 and the adjustable chuck 3 through the threaded connection of the end face, and setting the limiting device that the connecting ...
Embodiment 2
[0029] Such as image 3As shown, the adjustable chuck 3 of this embodiment uses the second motor 34 to adjust the position of the connecting claw 4 in the radial direction of the chuck. Specifically, the adjustable chuck 3 includes a fixed disk 31, a rotating disk 32, and a blocking disk 33; the fixed disk 31, the rotating disk 32, and the blocking disk 33 are coaxially arranged; one end of the fixed disk 31 is connected to the rotating shaft 2. The other end of the fixed disc 31 is provided with a cavity 311 for accommodating the turntable 32, the turntable 32 is placed in the cavity 311, and the turntable 32 and the fixed disc 31 are rotatably connected, and the rotatably connected This is achieved by inserting the matching shaft 310 on the fixed disk 31 into the matching hole 321 of the rotating disk 32 . The turntable 32 has an end face thread 320; the connecting claw 4 is composed of three parts, the first part 40 has an end face matching thread 400 matched with the end ...
