Description

Technical Field

[0001] The utility model relates to the technical field of submersible motor welding, in particular to a submersible motor segment welding device. Background Art

[0002] Submersible screw pump is one of the commonly used oil production equipment in the oil field industry. It is mainly composed of submersible motor, protector, connecting shaft, screw pump, oil outlet pipe and other components. Among them, the submersible motor in the submersible screw pump needs to output a large torque, and it is usually assembled and welded into a large direct-drive motor in the shape of a long strip by assembling multiple motor units. At present, the welding process between motor units often uses multiple pairs of parallel and rotatable support rollers or support rollers on the welding processing table to position and support each motor unit, and then manually adjust the position of each motor unit so that each motor unit is aligned head to tail. Finally, the manual hand-held welding equipment is used to rotate and weld each motor head and tail gap in turn to obtain the required submersible motor. The above-mentioned manual welding process of adjusting the position of the motor unit is not only labor-intensive and inefficient, but also frequently moves the motor unit on the support roller or support roller, which will also wear the support roller or support roller, resulting in a decrease in the positioning accuracy of the motor unit and a decrease in the welding quality.

[0003] In addition, during the rotation welding process of each motor unit, it is necessary to manually fix the motor unit housing with one hand. Although this can prevent the motor unit from rotating abnormally, as more motor units are welded, not only does the difficulty and strength of manually fixing the motor unit with one hand increase, but it is also extremely difficult to stably control the rotation of the motor, resulting in a decrease in welding quality.

[0036] The working principle of this embodiment:

[0037] When welding and processing of submersible motors is required, each motor unit is first placed on two pairs of support rollers 10 and 11 on each mobile support platform 2 by means of a lifting device; then the worm gear 74 and worm 751 reduction motor 32 on each mobile support platform 2 are started to control the drive gear 33 to rotate and mesh with the rack 31. Since the rack 31 is fixed on the welding processing table 1 and the gear 33 rotates at the bottom of the mobile support platform 2, the mobile support platform 2 will slide on the welding processing table 1 under the meshing of the gear 33 and the rack 31, thereby replacing manual movement of the motor units to move them closer to each other and align them head to tail;

[0038] Then the turning cylinder 61 will extend the piston rod, so that the piston rod pushes the connecting rod 1 62 and the connecting rod 2 63. Since one end of the shorter connecting rod 1 62 is hinged on the handle body 51 of the motor pressure rod 5, and one end of the longer connecting rod 2 63 is hinged on the hinged support plate 451 on the U-shaped mounting plate 45, and the angle between the connecting rod 1 62 and the connecting rod 2 63 is an acute angle, the connecting rod 1 62 and the connecting rod 2 63 will drive the motor pressure rod 5 to turn relative to the U-shaped mounting plate 45 under the push of the piston rod. At the same time, the motor pressing assembly 7 including the T-shaped bracket 71, the Y-shaped plate 72, the driving shaft 73, the driven shaft 76 on the U-shaped fork 52 of the motor pressure rod 5 will turn over to the upper part of the housing close to the motor unit;

[0039] Afterwards, the compression belt 79 mounted on the pulley 1 77 of the driving shaft 73 and the pulley 2 78 on the two driven shafts 76 will contact and press on the top of the motor unit shell, thereby realizing automatic compression and fixation of the motor unit. If it is necessary to control the motor unit to rotate for rotation welding at this time, the servo motor 75 can be started to drive the worm 751 to rotate and engage the worm wheel 74, so that the worm wheel 74 drives the driving shaft 73 to rotate. Finally, the pulley 1 77 on the driving shaft 73 will drive the compression belt 79 to move, so that the friction of the compression belt 79 drives the motor unit to rotate, thereby replacing manual work to achieve the effect of automatically fixing the motor unit and automatically controlling the stable rotation of the motor unit.

[0040] The automatic movement structure, automatic fixing, rotation control and other structures of the above-mentioned motor unit not only reduce the high labor-intensive tasks such as manual movement and fixing of the motor, but also the automatic movement and automatic fixing are faster and more stable than manual methods. Therefore, while improving the welding processing efficiency of the submersible motor to a certain extent, it also effectively guarantees the welding quality of the submersible motor.
