Description

Technical Field

[0001] This utility model relates to the technical field of motor manufacturing, and in particular to a motor rotor balance block riveting device. Background Technology

[0002] In the motor manufacturing process, rotor dynamic balancing is a critical step. In order to correct the rotor imbalance, balance blocks are usually riveted to specific positions on the rotor.

[0003] Existing motor rotor balance block riveting devices, such as the refrigeration compressor motor rotor balance block riveting machine disclosed in utility model patent application number 201220546976.5, mainly include a frame, an upper pressing mechanism, a lower pressing mechanism, a pushing mechanism, a discharging mechanism, a pressurizing device, and a control center. In use, the rotor semi-finished product is placed on the workbench at the punched center hole and positioned. The inner hole of the rotor is aligned with the punched center hole of the workbench. The pressurizing device drives the upper hydraulic rod of the upper pressing mechanism to move down and the lower hydraulic rod of the lower pressing mechanism to move up, until the riveting head of the upper hydraulic rod and the lower pressure head of the lower hydraulic rod are pressed into the inner hole of the stator.

[0004] However, most existing riveting devices require manual loading and unloading, resulting in low work efficiency and unsuitability for mass production. Furthermore, motor rotor balance blocks typically have two or more riveting points, and existing riveting devices often require manual adjustment of the riveting position, which is very troublesome. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a motor rotor balance block riveting device that not only facilitates the loading and unloading of the rotor, improving work efficiency and facilitating continuous manufacturing in the factory, but also facilitates the rotation of the rotor and the adjustment of the riveting position, eliminating the trouble of manual adjustment and positioning.

[0006] This utility model discloses a motor rotor balance block riveting device, including a riveting mechanism; it also includes a guiding mechanism, a driving mechanism, a bearing mechanism, a lifting mechanism, and a rotating mechanism.

The lifting mechanism is installed on the riveting mechanism and drives the rotating mechanism to rise and fall. The rotating mechanism is installed on the lifting mechanism and drives the bearing mechanism to rotate. The operator places the rotor semi-finished product on the bearing mechanism. The driving mechanism drives the bearing mechanism to move on the guiding mechanism. When the bearing mechanism moves to the riveting position, the riveting mechanism performs riveting processing on it. Then, the lifting mechanism pushes the rotating mechanism to lift, and the rotating mechanism drives the rotor semi-finished product on the bearing mechanism to rotate, which facilitates the adjustment of the riveting position. After the riveting is completed, the lifting mechanism drives the rotating mechanism to fall, and the driving mechanism drives the bearing mechanism and the rotor to unload.

The four sets of transmission wheels are mounted on the four sets of rotating shafts respectively, and the toothed conveyor belts are tensioned and mounted on the two sets of transmission wheels on the same side. When the dual-head motor is started, the dual-head motor drives the two sets of rotating shafts to rotate synchronously through the two sets of right-angle steering gears. The rotating shafts drive the transmission wheels to rotate, thereby driving the two sets of toothed conveyor belts to rotate synchronously.

[0010] Preferably, the carrying mechanism includes a pallet, two sets of racks, a turntable, and a positioning seat. The pallet is slidably mounted on two sets of guide rails. Both sets of racks are mounted on the pallet and mesh with two sets of toothed conveyor belts respectively. The turntable is rotatably mounted on the pallet, and the positioning seat is mounted on the turntable. The bottom of the positioning seat has a positioning groove. The operator places the rotor semi-finished product, which is pre-set with balance blocks and rivets, on the positioning seat. The two sets of toothed conveyor belts and the two sets of racks mesh and drive, thereby driving the pallet forward along the two sets of guide rails.
