Description

A housing and stator heat fitting mechanism Technical Field

[0001] This invention relates to the field of thermal fitting technology for housings and stators, and more particularly to a thermal fitting mechanism for housings and stators. Background Technology

[0002] The installation of a motor utilizes the principle of thermal expansion and contraction. First, the motor casing is heated to expand, and then the stator is placed inside the expanded casing. After the casing cools down, the casing and stator are installed. During installation, the motor casing is prone to tilting and falling over, making it impossible to install the stator. Furthermore, it is difficult to reset the casing after tilting and to re-center the motor. Traditional casing-stator heat-fitting mechanisms can only fit casings and heat-fitting devices of a single size, and cannot be adjusted according to the actual needs of the stator and casing sizes, thus limiting the applicability of the device. To solve this problem, we have redesigned a casing-stator heat-fitting mechanism. Summary of the Invention

[0012] Compared with related technologies, the housing and stator heat-shrink mechanism provided by the present invention has the following advantages:

[0013] This invention provides a heat-shrinking mechanism for the housing and stator. The stator is installed at the wedge-shaped inner support positioning and clamping mechanism at the top of the heat-shrinking lower clamping mechanism. After installation and fixation, the heat-shrinking lower clamping mechanism and the inner support clamping and unlocking mechanism are directly and fixedly connected. A housing is installed inside the housing heating coil, and the housing is directly clamped by two symmetrical housing jaws. Simultaneously, the housing clamping cylinder presses and fixes the housing from the top. The second housing heating coil heats the housing, increasing its inner diameter. The housing and stator are directly squeezed together for a heat-shrinking connection. After the connection is complete, cooling is achieved by blowing air through a cooling nozzle. As the housing cools, it contracts, enveloping the entire stator, thus completing the entire heat-shrinking process between the housing and stator.

[0014] This invention provides a heat-shrinking mechanism for the housing and stator. The housing is fixedly connected by a bird's beak clamping mechanism, which increases the ease of fixing and facilitates the disassembly of the bird's beak clamping mechanism and the housing. This allows for easy replacement of different specifications of wedge-type inner support positioning and clamping mechanisms for the fitting of different stators.

[0015] This invention provides a shell and stator heat fitting mechanism, which is directly mounted on the bird beak unlocking hook block via a bird beak clamping mechanism. Simultaneously, the entire inclined wedge-type inner support positioning clamping mechanism is connected to the inner support mechanism unlocking top block. The bird beak unlocking opening cylinder controls the height of the bird beak unlocking hook block, while the inner support mechanism unlocking retraction cylinder controls the height of the inner support mechanism unlocking top block. This, in turn, controls the overall height of the inclined wedge-type inner support positioning clamping mechanism. By controlling the height, the fitting depth of different shells can be controlled, improving the flexibility of the fitting operation and increasing the overall versatility of the device.

A second housing heating coil 14 is fixedly installed. An infrared temperature sensor 15 is fixedly installed on one side of the second housing heating coil 14. The housing is detachably installed inside the housing heating coil 9. The housing gripper 10 is connected to the housing by clamping. The housing clamping cylinder 7 is connected to the housing by top compression. A cooling pipe is installed inside the heating coil transformer 12. The cooling pipe and the cooling nozzle 8 are connected. A housing is fixedly installed on one side of the top of the heat jacket lower clamping mechanism 2.

[0026] In the implementation plan, the stator is installed at the inclined wedge-type inner support positioning and clamping mechanism 17 at the top of the heat-shrinking lower clamping mechanism 2. After installation and fixation, the heat-shrinking lower clamping mechanism 2 and the inner support clamping and unlocking mechanism 3 are directly fixedly connected. A housing is installed inside the housing heating coil 9, and the housing is directly clamped by the symmetrical housing jaws 10 on both sides. At the same time, the housing clamping cylinder 7 presses and fixes the housing from the top. The second housing heating coil 14 heats the housing, thereby increasing the inner diameter of the housing. The housing and stator are directly squeezed and fitted together. After the fitting is completed, the cooling nozzle 8 blows air to cool the housing.

[0027] Please refer to Figures 1-7. Based on Embodiment 1, the present invention provides a technical solution: the bird beak clamping mechanism 21 includes a mounting base 211.

The housing bird beak clamping head 215 and the mounting base 211 are connected by a movable connector. A vent hole 216 is provided at the bottom end of the mounting base 211.

[0028] In the implementation example, the bird beak clamping mechanism 21 is used to fix the housing, increasing the ease of fixing and facilitating the disassembly of the bird beak clamping mechanism 21 and the housing. This allows for easy replacement of different specifications of the wedge-type inner support positioning clamping mechanism 17 for different stator connection operations. Example

[0029] Please refer to Figures 1-7. Based on Embodiment 1, the present invention provides a technical solution: the inclined wedge-type internal support positioning and clamping mechanism 17 includes an internal support clamping flap 171. A fixed positioning seat 172 is fixedly installed on the edge of the internal support clamping flap 171. A mechanism base 173 is fixedly welded to the bottom end of one side of the fixed positioning seat 172. A spreading spring 174 is fixedly installed on the bottom surface of one side of the internal support clamping flap 171. A piston shaft 175 is provided inside the internal support clamping flap 171. A retraction spring 176 is provided at the connection between the internal support clamping flap 171 and the mechanism base 173. The unlocking mechanism 3 includes a mounting base 22. An inner support mechanism unlocking retraction cylinder 25 is fixedly mounted at the top center of the mounting base 22. An inner support mechanism unlocking top block 26 is movably connected to the top of the inner support mechanism unlocking retraction cylinder 25. Bird beak unlocking opening cylinders 23 are fixedly mounted on both sides of the top of the mounting base 22. Bird beak unlocking hook blocks 24 are movably connected to the top of each bird beak unlocking opening cylinder 23. The connection relationship between the bird beak unlocking hook block 24 and the unlocking block 214 is a clamping connection. The connection relationship between the inner support mechanism unlocking top block 26 and the inner support clamping flap 171 is a clamping connection.

[0030] In the implementation case, the bird beak clamping mechanism 21 is directly installed on the bird beak unlocking hook block 24. At the same time, the entire inclined wedge-type inner support positioning clamping mechanism 17 is connected to the inner support mechanism unlocking top block 26. The bird beak unlocking opening cylinder 23 can control the height of the bird beak unlocking hook block 24, and the inner support mechanism unlocking retraction cylinder 25 can control the height of the inner support mechanism unlocking top block 26. In turn, the overall height of the inclined wedge-type inner support positioning clamping mechanism 17 can be controlled. By controlling the height, the control of different shell fitting depths can be achieved, improving the flexibility of fitting operations and increasing the overall versatility of the device.

[0031] Working principle:

[0032] The stator is installed at the inclined wedge-type inner support positioning and clamping mechanism 17 at the top of the heat fitting lower clamp mechanism 2. After installation and fixation, the heat fitting lower clamp mechanism 2 and the inner support clamping and unlocking mechanism 3 are directly fixedly connected. A shell is installed inside the shell heating coil 9. The shell is directly clamped by the shell clamping claws 10 on both sides. At the same time, the shell clamping cylinder 7 presses and fixes the shell from the top. The shell is heated by the second shell heating coil 14, which increases the inner diameter of the shell. The shell and stator are directly squeezed and fitted together. After the fitting is completed, the cooling nozzle 8 blows air to cool down the shell. The shell can shrink and wrap the entire stator, thus realizing the whole process of heat fitting between the shell and the stator.

[0033] The bird beak clamping mechanism 21 secures the housing, simplifying the fixing process and facilitating disassembly between the mechanism and the housing. This allows for easy replacement of different specifications of the wedge-type inner support positioning clamping mechanism 17 for different stator fitting operations. The bird beak clamping mechanism 21 is directly mounted on the bird beak unlocking hook block 24. The wedge-type inner support positioning clamping mechanism 17 is connected to the inner support mechanism unlocking top block 26. The bird beak unlocking opening cylinder 23 controls the height of the bird beak unlocking hook block 24, while the inner support mechanism unlocking retraction cylinder 25 controls the height of the inner support mechanism unlocking top block 26. This, in turn, controls the overall height of the wedge-type inner support positioning clamping mechanism 17. By controlling the height, the fitting depth of different housings can be controlled, improving the flexibility of the fitting operation and increasing the overall versatility of the device.

[0034] The XY floating head 4 can move in the X and Y directions to generate different torques. The suction pipe 13 is directly connected to the suction hood 5 to absorb the smoke and dust generated by heating in a timely manner, improving the cleanliness of the working environment. The cooperation between the stator positioning component 19 and the stator support column 18 facilitates the confirmation of the position between the shell and the stator, ensuring the effect of precise fitting.

[0035] The function of the beak clamping mechanism is to clamp the shell flange after heat fitting, keeping the shell flange surface in contact with the lower clamping surface. This is because the shell and stator will rebound during the cooling and shrinkage process after fitting, requiring a certain force to keep the shell surface in contact with the tooling. The unlocking mechanism below the beak clamping mechanism keeps the shell beak clamping head 215 open during heat fitting; otherwise, the shell will collide with this clamping head 215 during the heat fitting process. If the product stator is different, the lower clamping fixture is quickly switched to different wedge-type internal support mechanisms. If the shell height is different, the upper clamping shell clamping block switching cylinder 11 automatically switches to the appropriate shell height.
