Description

Technical Field

[0002] According to ISO standards, a rotating body supported by a bearing is called a rotor. Rotors are mostly the main rotating parts in power machinery and working machinery. Typical rotors include turbine machinery rotors, motor rotors, rotors of various pumps, and rotors of turbine compressors. Usually, the structure of a rotor includes an iron core in the middle section and a rotating shaft at both ends of the iron core. Before the rotor and stator are assembled, it is necessary to install an E-type retaining ring and a bearing on the rotating shaft of the rotor. The E-type retaining ring is also called an E-type retaining ring. It is a kind of fastener that is installed in the shaft groove of a machine or equipment to prevent the axial movement of parts on the shaft. Because its shape is like an E-shape, people are accustomed to calling it an E-type retaining ring.

[0003] The assembly process of the rotor is mostly done manually, and the assembly mainly includes the following steps: the first step is that the worker clamps the circlip with a circlip pliers, and then holds the two handles of the circlip pliers to open the circlip so that the circlip can be smoothly inserted into the rotating shaft. When the circlip is inserted into the predetermined position, the two handles are released, and the circlip is firmly stuck in the circlip position of the rotating shaft; the second step is that the worker pushes the bearing into the rotating shaft through a bearing installation tool, such as a bearing push device, and finally fixes the bearing in the predetermined position of the bearing.

The feeding mechanism 2 is arranged on the side of the workbench 1, and comprises a vibrating plate 21 for placing springs and a spring output slideway 22 connected thereto; the spring output slideway 22 extends toward the workbench 1; the material shifting mechanism 3 and the rotor fixing mechanism 4 are arranged on the workbench 1 in parallel front and back, and the material shifting mechanism 3 is used to receive the springs conveyed by the spring output slideway 22; the rotor The fixing mechanism 4 is used to fix the rotor with the retaining spring to be pressed; the first pressing mechanism 5 is arranged on the side of the workbench 1, and is located on one side of the material moving mechanism 3 and the rotor fixing mechanism 4, and is used to grab the retaining spring on the material moving mechanism 3, and move it to the rotor fixing mechanism 4 to press the retaining spring on one side of the rotor; the second pressing mechanism 6 is installed horizontally on the workbench 1, and is located on the other side of the material moving mechanism 3 and the rotor fixing mechanism 4, and is used to grab the retaining spring on the material moving mechanism 3, and move it to the rotor fixing mechanism 4 to press the retaining spring on the other side of the rotor. It can be seen from this that the equipment of the present invention mainly automates the press-fitting process of the retaining springs on both sides of the rotor. The retaining springs are placed in batches in the vibrating plate, the vibrating plate automatically vibrates the retaining springs out, and then outputs the retaining springs through the retaining spring output slideway. The material moving mechanism can move left and right on the workbench to receive the conveyed retaining springs, and can move close to the first press-fitting mechanism and the second press-fitting mechanism on both sides. Since there are retaining springs on both sides of the rotor that need to be press-fitted, the material moving mechanism needs to receive two retaining springs at a time, and then slide to the first press-fitting mechanism. The first press-fitting mechanism can move left and right, front and back, and can be lifted and lowered to grab the retaining springs on the material moving mechanism, and then move to the rotor fixing mechanism. After the retaining springs are placed on the rotor where the retaining springs need to be press-fitted, the material moving mechanism moves toward the direction of the second press-fitting mechanism, and the second press-fitting mechanism can move left and right to grab the retaining springs on the material moving mechanism and then move to the rotor fixing mechanism to press the retaining springs into the other side of the rotor where the retaining springs need to be press-fitted. In this way, the entire press-fitting process is completed quickly and accurately.
