Description

Technical Field

[0001] The invention relates to the technical field of sealing ring press-fitting, and more specifically to a motor shaft sealing ring press-fitting device. Background Art

[0002] The motor shaft seal is a key component used to prevent the motor from being contaminated by liquid or solid particles. As the application field of motors continues to expand, the performance requirements for motor shaft seals are becoming higher and higher. However, there are many problems in the traditional installation process of motor shaft seals, which seriously affect the operating efficiency and service life of the motor.

[0003] 1. Instability of manual operation

[0004] The traditional installation method of motor shaft seal rings mainly relies on manual operation. The operator needs to hold the seal ring and put it on the motor shaft, and then press it by knocking. Since manual operation is affected by the worker's technical level and physical condition, the instability during the installation process is relatively large. For example, when the operator takes the seal ring, it is difficult to ensure that the seal ring is perpendicular to the installation surface. This non-vertical state can easily cause the seal ring to tilt or warp during the installation process, which in turn affects the motor's operating efficiency and sealing and waterproofing effect.

[0005] 2. Scratches and damage issues

[0006] During manual operation, scratches are likely to occur between the seal ring and the motor shaft surface. Such scratches not only cause changes in the shape and size of the seal ring, but may also leave scratches on the motor shaft. These scratches will reduce the surface quality of the motor shaft, increase the friction coefficient, and even cause early wear and failure of the motor shaft. In addition, scratches may also damage the surface of the seal ring and affect its sealing performance.

[0007] 3. Low production efficiency

[0008] Due to the limitations of manual operation, the traditional motor shaft seal ring installation method has low production efficiency. Operators need to spend a lot of time and energy to complete the installation of each seal ring. This not only increases production costs, but also limits the production scale and market competitiveness of the motor.

[0009] 4. Security Risks

[0010] During manual operation, operators need to hold heavy objects and perform knocking actions for a long time, which can easily lead to operator fatigue and hand injuries. In addition, due to the risk of scratches and collisions during operation, the safety of operators is difficult to guarantee.

[0011] 5. Difficulty of quality control

[0012] Due to the instability of manual operation, the traditional motor shaft seal ring installation method has great difficulties in quality control. Each operator's skill level and operating habits are different, which leads to inconsistency in the quality of seal ring installation. In addition, due to the lack of effective quality inspection methods, it is difficult to detect and solve problems in the installation process in a timely manner.

[0013] At present, follow-up remedial measures are usually taken to deal with the above problems: ① When abnormal noise is detected at the motor test station, rework is carried out; ② When scratches are found on the shaft during the packaging stage, they are repaired by manual grinding. Although the existing solutions can alleviate the impact of the problem to a certain extent, the inaccuracy and instability in the manual installation process, as well as the resulting quality problems, have not been fundamentally solved.

[0014] Therefore, it is necessary to develop an automated and intelligent motor shaft sealing ring press-fitting device to improve production efficiency, reduce costs, protect the safety of operators, and ensure the installation quality of the motor shaft sealing ring. Summary of the invention

Although in the embodiment of the present invention, it is shown that two feeding mechanisms 2a, 2b are respectively arranged on both sides of the frame 1, it is also possible to arrange two feeding mechanisms on one side of the frame 1 and another feeding mechanism on the other side of the frame, and other numbers of feeding mechanisms are also feasible. The number of feeding mechanisms depends on the number of pressing heads, that is, a number of feeding mechanisms are arranged according to the number of pressing heads configured for the pressing mechanism in the press-fitting device, which can be configured according to actual needs.

[0066] Specifically, the frame 1 may include: a press-fitting operation table 10 for placing the motor M, the motor M being placed on a tooling plate 11, the tooling plate 11 being placed on the press-fitting operation table 10, and a radio frequency identification tag T being provided on the tooling plate 11, the radio frequency identification tag T carrying configuration information of the motor M on the tooling plate 11. As an example, the tooling plate 11 on which the motor M is placed is moved from the previous process to the press-fitting operation table 10 on the motor shaft seal ring press-fitting device.

[0069] In an embodiment of the present invention, the electric control system 3 may be connected to the press-fitting mechanism 13, the servo mechanism 14, the motor shaft positioning mechanism 15, and the feeding mechanisms 2a and 2b.

Figure 5Bshown).

[0075] like Figure 2 As shown, each motor shaft positioning assembly may include two symmetrically arranged tightening cylinders 150 ( Figure 2 Only one is shown in the figure, and another tightening cylinder is provided on the other symmetrical side). The two symmetrically arranged tightening cylinders 150 are opposite and spaced apart, and a clamping portion 151 is provided at the end of each tightening cylinder 150 (such as Figure 6B As shown in FIG. 1 , the clamping portion 151 has an arc inner surface, and the clamping portions 151 of the two symmetrically arranged clamping cylinders 150 cooperate to clamp the motor shaft MA of the lifted motor M, and the inner surface of the clamping portion 151 is in close contact with the shaft surface of the motor shaft MA.

[0090] c) Move the pressing mechanism to the position of the sealing ring picking platform, and align the selected pressing head with the sealing ring picking platform to automatically pick up the sealing ring. Figure 4A and Figure 4B As shown, a designated pressing head among the three pressing heads in the pressing mechanism 13 is aligned with the sealing ring picking table of the feeding mechanism 2a, and then automatically picks up the sealing ring.

[0091] d) Move the pressing mechanism 13 to the position just above the position to be pressed. Figure 5A and Figure 5B As shown, a designated pressing head 130 among the three pressing heads in the pressing mechanism 13 is positioned just above the motor shaft MA to be pressed.
