Description

Technical Field

[0002] There is a certain degree of interference fit between the armature and the casing at normal temperature and pressure. The commonly used method is to use a hot oven to heat the casing to a set temperature, allowing the casing to expand naturally using the principle of thermal expansion and contraction, so that the armature can easily enter the casing and realize the integrated assembly of the armature and the casing.

[0003] At present, commonly used assembly equipment such as a large torque motor armature assembly equipment disclosed in the patent application with publication number CN118249589A can effectively realize the mass production of armatures and housings and high-quality, high-performance, and high-reliability production, avoid impact during processing, and effectively ensure the magnetic saturation of materials. The existing armature assembly equipment forms a high-frequency induction magnetic field on the induction coil, and the high-frequency induction magnetic field performs magnetic induction heating on the motor housing. The armature and the clamping claw and other components move downward under the action of the high-precision vertical electric cylinder. When the lower half of the armature enters the housing, the bottom buffer electromagnet and the buffer electromagnet push rod are linked to realize magnetic support for the high-power density armature. By controlling the power of the buffer electromagnet and the vertical position posture of the buffer electromagnet push rod, combined with the real-time measurement value of the pressure sensor, the magnitude change of the electromagnetic thrust received by the high-power density armature is judged, and the measured value of the pressure sensor is used as input to adjust the power of the buffer electromagnet and the movement position of the buffer electromagnet push rod to ensure that the armature slowly enters the housing and the armature end face slowly contacts the armature support step inside the housing.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

By providing the contact block 6c, when the two half-circles 6a are misaligned with each other, the contact and power supply state is always maintained, thereby avoiding power failure between the two half-circles 6a. Furthermore, each of the half-circles 6a includes multiple layers of coils, and a support column 6d is provided between two adjacent layers of coils to play a reinforcing role.

In order to avoid shaking of the housing positioning and mounting assembly during press installation, the dual-axis cylinder 13 is used to push the positioning block 14 against the positioning groove 7a to avoid shaking.

[0045] Combination Fig.11 As shown, the driving mechanism includes an electric screw 15 and a single-rod cylinder 16; the electric screw 15 is installed on the partition 2, the tail end of the cylinder body of the single-rod cylinder 16 is connected to the screw nut on the electric screw 15, and the telescopic rod of the single-rod cylinder 16 is connected to the tooling mounting plate 7.

When heating, a high-frequency induction magnetic field is formed on the induction coil 6, and the high-frequency induction magnetic field performs magnetic induction heating on the motor housing 9. The temperature sensor 19 also monitors the temperature of the motor housing 9 in real time. When the temperature induction heating of the motor housing 9 reaches a preset temperature, the temperature closed-loop controller 21 controls the high-frequency heater 20 to stop working, thereby realizing temperature closed-loop control of the equipment with special anti-electromagnetic interference coating.

[0049] The armature assembly equipment provided in this embodiment mainly includes the following processes during operation:

[0050] S1. Place the high power density armature 10 into the armature clamping tool, and start the first clamping cylinder 28 and the second clamping cylinder 29 to clamp the high power density armature 10.

[0051] S2. Use the casing positioning and installation assembly to install the motor casing 9 to be heated, use the driving mechanism to drive the casing positioning and installation assembly to move along the guide rail 11 to just below the induction coil 6, use the rodless cylinder 4 to drive the induction coil 6 to descend and sleeve it on the outside of the motor casing 9 for heating. After the heating is completed, use the driving mechanism to drive the casing positioning and installation assembly to move along the guide rail 11 to just below the high-power-density armature 10, use the high-precision vertical electric cylinder 24 to drive the high-power-density armature 10 to descend, and install the high-power-density armature 10 into the motor casing 9.

[0052] S3. Before the high-power-density armature 10 is installed into the motor housing 9, the coaxiality of the high-power-density armature 10 and the motor housing 9 is detected by the laser interferometer 17. The electric screw 15 adjusts the coaxiality of the high-power-density armature 10 and the motor housing 9 in real time according to the measured size of the laser interferometer 17. In the process of position adjustment, in order to achieve a combination of rapid positioning and adjustable precision positioning, a dual combination design of the electric screw 15 and the single-rod cylinder 16 is adopted. The single-rod cylinder 16 can quickly realize the heated motor housing 9 to reach the heating position and the press-fitting position. The thermal stress of the induction heating will cause a certain position error. When the laser interferometer 17 detects that the coaxiality of the high-power-density armature 10 and the motor housing 9 has a large deviation, the coaxiality position is compensated and adjusted by the electric screw 15 to meet the high-precision press-fitting position requirements of the process.
