It has become one of the leading technologies for increasing oil field production and improving the ultimate recovery rate of difficult-to-use reserves. As a mainstream pneumatic control crawler, the main control component cylinder is composed of a cylinder barrel, an end cover, a piston, a piston rod and a seal. When the cylinder is working, the piston is lubricated by the oil mist in the compressed air. Usually, there is water in the compressed air. Water will corrode the cylinder barrel and decompose the oil mist, which is not conducive to lubrication and affects the service life of the cylinder. The cylinder liner, as the core component of the internal combustion engine, plays a vital role in the operation of the internal combustion engine. Due to the requirements of the working environment of the internal combustion engine, the inner surface of the cylinder liner has strict requirements in terms of dimensional accuracy, shape accuracy, roughness, etc. The specifications of the cylinder liner are different, and the weight of the blank is also different.

[0034] Specifically, start the motor 4 connected to the support plate 2 to drive the winding roller 5 to rotate. The rotation of the winding roller 5 will drive the lifting rope 6 to be wound. During the winding process, the lifting rope 6 will slide on the outer wall of the pulley 9, which can effectively reduce the wear of the lifting rope 6. It is worth mentioning that when the motor fails, we can also manually turn the handle 12 to drive the winding roller 5 to rotate. At this time, the lifting rope 6 will carry the movable plate 10 to slide on the outer wall of the vertical pole 7, realizing the movement of the movable plate 10, thereby driving the mounting plate 11 and the mechanical arm 13 to adjust the height after completing the above preparations.

[0035] Reference Figure 3-Figure 5The upper surface of the movable plate 10 is fixedly connected with a mounting plate 11, and the upper surface of the mounting plate 11 is rotatably connected with a mechanical arm 13.

[0036] Specifically, the robot arm 13 is started to drive the crossbeam 14 to move above the raw material. Then, the motor 2 15 is started to drive the screw 16 to rotate. The rotation of the screw 16 will cause the two sliding blocks 18 to slide on the outer wall of the guide rod 17, thereby adjusting the distance between the two sets of clamping plates 20. Subsequently, the cylinder body 19 connected to the sliding block 18 is started. The cylinder will drive the clamping plate 20 to move inward to clamp the raw material. At the same time, the micro air pump 21 is started to extract the air inside the vacuum suction cup 23 through the exhaust pipe 22, and the raw material is adsorbed by the vacuum suction cup 23 to improve the stability of the raw material clamping.

[0038] Specifically, when we need to start the device, first, by pushing the fixed seat, with the help of the rolling function of the universal wheel, the device is moved to the appropriate position, and then, the support rod 25 is pulled to drive the screw 26 to move. At this time, the handle 27 is turned to rotate the screw 26. This rotation will generate a force inside the support rod 25, so that the support foot 28 is in contact with the ground, thereby achieving the purpose of stabilizing the base 1 and the entire device.

[0039] like Figure 1 As shown, a safety shield is provided on the winding roller 5, and the lifting rope 6 passes through the guide rope hole on the safety shield. The safety shield is provided on the winding roller 5 to play a role of safety protection and improve the safety of the lifting fixture operation.
