Since it can be used in both rotary transmission and linear transmission, the motor can be seen in most mechanical transmission mechanisms of mechanical automation equipment. It can be said that in the field of automation The demand of various equipment manufacturers for motor products is also increasing day by day. Therefore, in order to meet the increasing market demand of customers for motor products, major motor manufacturing companies have begun to try their best to shorten the production cycle of motors and improve the efficiency of manufacturing, and the traditional manual assembly line assembly in the past It is an effective method to change the motor production mode of the operation to the motor automation production line mode, so the motor automation production equipment is gradually popularized and applied in various motor manufacturing enterprises.

From the perspective of the existing motor manufacturing process, the motor is mainly composed of two parts: the stator and the rotor. The stator and the rotor of the motor are important components for the motor to realize the conversion of electrical energy into mechanical energy. Whether it is the traditional manual operation mode or the current stage of automation The production mode is inseparable from the production and assembly of the motor stator and rotor. Among them, the motor rotor, as the rotating body of the motor torque output, can be said to be one of the most important parts of the motor as the middle core of the motor. In order to ensure the stability and accuracy of the motor rotor rotation in the production process, it is often necessary The two ends of the rotor shaft are respectively equipped with fixed shaft sleeves, bearings and other parts, so the assembly of the motor rotor usually refers to the process of installing the fixed shaft sleeve and bearings on the motor rotor shaft, so the quality of the production and assembly of the motor rotor Control and production efficiency often determine the quality and production cycle of the entire motor. Although at the present stage, with the promotion and application of motor automation production lines, the production and assembly of motor rotors can basically be completed by equipment automation, but there are still problems that need to be solved urgently in the current automatic assembly and production of motor rotors. positioning problem.

Low. For some devices applicable to the positioning of various types of motor rotors, although they can meet the needs of coaxial positioning of various motor rotors, when operating, it is often necessary to manually adjust the positioning device for positioning the motor rotors for different motor rotor products ( For example, a patent: the patent number is: CN202021803765.6, the name is: a motor rotor bearing press-fitting device), which is not only cumbersome and time-consuming, but also has certain requirements for the technical level of the operator, which is extremely detrimental to the quality Control and automate production. It can be seen that once the motor automation production line is replaced to produce different motor products, the motor rotor automatic assembly link must first manually replace the corresponding rotor positioning fixture or manually adjust the rotor positioning device, regardless of which method is adopted. In this way, the problems of high pertinence, low adaptability, poor versatility, cumbersome adjustment, time-consuming, low flexibility, and low efficiency still exist in the assembly and positioning of the motor rotor.

The motor rotor flexible positioning pressurized bearing device can automatically coaxially clamp and position and pressurize bearings for multiple different types of motor rotors with the same shaft diameter. For example: the motor rotors shown in Fig. 13 to Fig. 15 are loaded with pressure bearings, and the shaft diameters of the positions for bearing pressure at both ends of these motor rotors are the same.

Its workflow is as follows:

As shown in Figures 16 to 19, first the rotor shaft of the product A is automatically grabbed by the robot manipulator and placed on the lifting adjustment mechanism 3. At this time, the left and right ends of the rotor shaft are respectively placed in the left support gap 330 and the right support gap 340 Middle; then the lifting adjustment mechanism 3 raises the rotor shaft of product A to a specified height, ensuring that the axis of the rotor shaft of product A at this time coincides with the axes of the left sleeve pressure hole 10 and the right sleeve pressure hole 20; then clamp The clamping cylinder 21 of the clamping mechanism 2 drives the front clamping part 22 and the rear clamping part 23 to move closer to the center to clamp the iron core of the rotor shaft of the product A synchronously; the front clamping part 22 and the rear clamping part 23 are clamped in place Afterwards, the elevating frame 32 of the lifting adjustment mechanism 3 then descends and retracts back to its original position and leaves the rotor shaft of the product A. 23 still coincides with the axes of the left press hole 10 and the right press hole 20 under the joint action of 23.

As shown in Figure 20 to Figure 23, then the robot manipulator automatically grabs the fixed shaft sleeve and fits it on the rotor shaft of product A, and the left and right ends of the rotor shaft must be fitted with the fixed shaft sleeve; then the robot manipulator automatically grabs The bearings are respectively loaded into the left sleeve pressure hole 10 and the right sleeve pressure hole 20; because the front and rear hole walls of the left sleeve pressure hole 10 are respectively symmetrically provided with the left elastic top pressure ball body 101 and the front and rear hole walls of the right sleeve pressure hole 20 respectively The right elastic top pressure ball body 201 is symmetrically arranged, so when the robot manipulator automatically grabs the bearing and puts it into the left bushing hole 10 and the right bushing hole 20 respectively, the outer ring of the bearing will put the left bushing hole 10 and the right bushing hole The balls inside 20 are extruded, because the forces are interactive, and at this time, the outer rings of the bearings installed in the left sleeve pressure hole 10 and the right sleeve pressure hole 20 will be simultaneously squeezed by the reaction force of the balls Positioning, thereby ensuring that the bearings that are packed into the left sleeve pressure hole 10 and the right sleeve pressure hole 20 will not fall off due to mechanism vibration or slight touch when the manipulator of the robot leaves the reset. And after ensuring that the manipulator of the robot is away from the safe range, the left drive cylinder 30 and the right drive cylinder 40 start working simultaneously, the left drive cylinder 30 retracts, and the right drive cylinder 40 stretches out to drive the left sleeve pressing mechanism 4 and the right cover respectively. The pressing mechanism 5 moves towards the direction close to the rotor shaft of the product A at the same time. When the left driving cylinder 30 and the right driving cylinder 40 are both in place, the pressing of the left casing pressing hole 10 and the right casing pressing hole 10 in the left casing pressing mechanism 4 are respectively completed. The bearings on the right bushing pressure hole 20 in the mechanism 5 are respectively loaded on the shafts on the left and right sides of the product A rotor shaft that has been clamped by the clamping mechanism 2 and has completed the assembly of the fixed shaft sleeve.

So far, the installation of the fixed shaft sleeve and the bearing on the rotor shaft of product A has been completed, that is, the assembly of the product A rotor has been completed. As shown in Figure 24 to Figure 25, then the front clamping part 22 and the rear clamping part 23 of the clamping mechanism 2 are reset away from the rotor of the product A, so as to reserve enough space for the robot manipulator to grab the rotor of the assembled product A to the next assembly station for use. And when the robot manipulator is in place to clamp the rotor of product A, the left drive cylinder 30 and the right drive cylinder 40 start to reset simultaneously, the left drive cylinder 30 stretches out, and the right drive cylinder 40 retracts to drive the left sleeve pressing mechanism 4 and the right The sleeve pressing mechanism 5 moves backward in the direction away from the rotor of product A at the same time, at the same time, the left ejector mechanism 6 and the right ejector mechanism 7 move respectively, and the left ejector cylinder 62 of the left ejector mechanism 6 moves from left to right Eject out the bearing installed in the left sleeve pressure hole 10, and the right ejector tube 72 of the right ejector mechanism 7 ejects the bearing in the right sleeve pressure hole 20 from right to left. Thus, it is ensured that the bearings mounted on the left bushing hole 10 and the right bushing hole 20 can be smoothly installed on the left and right ends of the rotor shaft of product A every time, avoiding the problem that the machining accuracy of the rotor shaft of product A is not in place. When it fits loosely with the inner hole of the bearing, sometimes the bearings on the left bushing pressure hole 10 and the right bushing pressure hole 20 cannot be installed on the rotor shaft of product A when the left bushing pressure mechanism 4 and the right bushing pressure mechanism 5 are retracted and reset. In the case of product A, reduce the matching accuracy requirements between the rotor shaft of product A and the inner hole of the bearing, and improve the success rate of automatic pressure loading of the rotor bearing of product A. So far, the assembly process of product A rotor has been completed.

And when the production line is switched from producing motor product A to motor product B with the same shaft diameter, because the two V-shaped clamping notches on the clamping mechanism 2 (the front V-shaped clamping notch 220 and the rear V-shaped clamping notch 230 ) can be suitable for centering and clamping iron cores of various diameters, and the lifting adjustment mechanism 3 can ensure that the rotor shafts of different types of motors with the same shaft diameter are automatically raised to the position of the left sleeve pressure hole 10 and the right sleeve pressure hole 20 The height positions where the three axes coincide, so as long as the shaft diameter of the motor product does not change, it can ensure that the rotor shafts of different types of motors are clamped and positioned in the clamping mechanism 2. The axes of 20 coincide, so that the above-mentioned assembly action process can be repeated to automatically complete the assembly process of motor rotors with different types of coaxial diameters, eliminating the need to manually replace the corresponding rotor positioning jig or manually adjust the rotor positioning device. While improving the efficiency, the flexibility of the device is also improved.

The above-mentioned embodiments are preferred embodiments of the present invention, and all structures similar to those of the present invention and equivalent changes made should fall within the scope of protection of the present invention.
