Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor rotor core processing technology, specifically to a riveting fixture for motor rotor cores. Background Technology
[0002] The rotor core is made by stacking rotor laminations in a certain pattern, connecting them with rivets, and then using a hydraulic press to flatten the rivet heads, so that the rotor laminations are stacked into the rotor core. At the same time, the rivet connection also ensures the structural strength of the rotor core.
[0003] After the rotor cores are stacked, they need to be riveted and tightened. Using manual riveting one by one is inefficient, the riveting pressure is uneven, and the consistency is poor. Moreover, the cores are prone to displacement during riveting, which leads to product quality problems. Utility Model Content
[0004] The main objective of this invention is to provide a riveting fixture for motor rotor cores to solve the aforementioned technical problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a riveting fixture for a motor rotor core, comprising a conveyor table, a conveyor track on the conveyor table, a riveting device on one side of the conveyor track, and a limiting structure on one side of the riveting device; a photoelectric receiver and a photoelectric transmitter are provided below the riveting device, and the photoelectric receiver and photoelectric transmitter are symmetrically arranged on both sides of the conveyor track; a main control device is also provided on the conveyor table.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the riveting device includes a frame, a hydraulic cylinder is provided on the frame, and a riveting plate is provided at the output end of the hydraulic cylinder.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting structure includes a cross frame, a motor is provided on one side of the cross frame, a bidirectional lead screw is provided at the output end of the motor, a first threaded seat and a second threaded seat are provided on the bidirectional lead screw, a first limiting block and a second limiting block are respectively provided at the bottom of the first threaded seat and the second threaded seat, and the first limiting block and the second limiting block are located directly below the riveting device.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the first limiting block and the second limiting block are arc-shaped structures.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the front end of the conveyor is provided with a control panel, the main control device is set on the control panel, and the photoelectric receiver, photoelectric transmitter, motor and hydraulic cylinder are electrically connected to the main control device respectively.
[0010] The beneficial effects of this utility model are as follows: In this utility model, by setting up a conveyor table, the iron core is placed on the conveyor track of the conveyor table. When the iron core is conveyed to the position between the photoelectric receiver and the photoelectric generator, the main control device controls the conveyor belt to stop moving. Then, by controlling the motor to rotate, it drives the bidirectional lead screw to move, so that the first threaded seat and the second threaded seat move towards each other. At this time, the first limit block and the second limit block approach each other and limit the iron core. Then, by starting the hydraulic cylinder, the riveting plate drives the riveting plate to rivet the iron core, ensuring that the iron core does not deviate during riveting and improving the riveting efficiency.
