Embodiment Construction
[0028] refer to Figure 1 to Figure 2 , the present invention provides a motor rotor guide bar rolling compression expansion machine, including a frame 1, a guide rail is fixed on the frame 1, and a workbench 2 that can slide left and right along the guide rail is installed on the guide rail. The upper surface of the platform 2 is rollingly installed with two supporting cylinders 2-1 whose axial direction is parallel to the length direction of the guide rail. The cylinder walls of the supporting cylinders 2-1 abut against the outer wall of the rotor to support the rotor; The right end is fixed with a first driving mechanism 3, and the first driving mechanism 3 is connected with the rotor through a linkage structure 4 to drive the rotor to rotate; it also includes a rolling mechanism 5 installed on the frame 1, and the rolling mechanism 5 includes The second driving mechanism 6 that moves up and down with the roller 5-1 that presses against the guide bar and the driving roller ...

The invention relates to the related field of a motor rotor assembly device and particularly relates to a motor rotor bar rolling tension machine. The invention aims to solve a technical problem thatan existing collision mode has high noise and the quality is difficult to guarantee. The Motor rotor bar rolling tension machine provided by the invention is provided with two support cylinders for supporting a rotor, a roller which can move up and down and a movable worktable, the roller performs rolling and tensioning along a single bar through the movement of the movable worktable, and a firstdriving mechanism for rotating the rotor is also set to complete the rolling of all bars one by one. Compared with an existing collision tension mode, on one hand, the noise is greatly reduced and canbe controlled to be lower than 30 decibels, on the other hand, dimensional tolerances such as depth and width can be controlled at 0.03mm, and the tension accuracy and quality are greatly improved. Moreover, compared with an existing automatic collision tension machine, 50% of processing time can be saved for the rolling and tension of each rotor, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the related field of motor rotor assembly equipment, in particular to a motor rotor guide bar rolling and expansion machine. Background technique [0002] After the motor guide bar is embedded in the rotor slot, it needs to be tightened to ensure the firmness of the connection between the guide bar and the rotor. There are two main ways to tighten the existing guide bars: [0003] One is a hand-held impact tensioner. During operation, put the impact head into the rotor slot, open the start valve, and move the impact machine evenly in the axial direction while the impact head impacts the expansion type. After one slot has been expanded, check the impact depth. If the depth is shallow, impact again , to ensure that the expansion depth meets the tolerance until all the grooves are collided. There are three main disadvantages in this method: one is that the labor intensity is high, and it takes a lot of physical strength of the ...
