Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a hot pressing device for a motor stator end cover. Background Art

[0002] Before the stator end cover of the motor is pressed together with the stator of the motor, the stator usually needs to be heated first to facilitate hot pressing. When using the existing hot pressing equipment, multiple motor stators to be pressed need to be placed in a heating furnace for heating, and then transported to the pressing equipment one by one, and then pressed together with the stator end cover. This operation method is time-consuming and labor-intensive, and it is impossible to accurately control the temperature of the motor stator during press-fitting. The temperature of some stators is inconsistent during press-fitting due to the long interval heating time. There may also be a large drop in the temperature of the stator heated first, which does not meet the requirements of hot pressing. The above will lead to poor hot pressing effect and reduce the yield rate of the motor. Summary of the invention

[0061] As a preferred embodiment of the present invention, the present invention provides a motor stator end cover hot pressing device, comprising:

[0062] frame;

[0063] A stator press-fitting mechanism is arranged on the frame and is used to carry the wound stator block and drive the stator block to perform lifting motion;

[0064] An end cover clamping mechanism, arranged at the top of the stator press-fitting mechanism, for clamping the stator end cover press-fitted with the stator block;

[0065] A pre-press-fitting heating mechanism, arranged beside the stator press-fitting mechanism, for heating the stator end cover clamped in the end cover clamping mechanism;

[0066] A high-frequency heating power supply is arranged beside the pre-press-fitting heating mechanism and is electrically connected to the pre-press-fitting heating mechanism, and is used to energize the pre-press-fitting heating mechanism;

[0067] The process switching mechanism is arranged on the frame and is drivingly connected with the end cover clamping mechanism, and is used to drive the end cover clamping mechanism to move between the stator pressing mechanism and the pre-pressing heating mechanism to switch the process.

[0068] Through the design of the hot pressing equipment, different from the traditional hot pressing method, the process switching mechanism drives the end cover clamping mechanism to slide horizontally between the pre-pressing heating mechanism and the stator pressing mechanism to switch the process, wherein the pre-pressing heating mechanism heats the stator end cover clamped and held by the end cover clamping mechanism, and the stator pressing mechanism drives the stator block placed thereon to be hot-pressed toward the held stator end cover, so that the temperature of the motor stator during press-fitting can be accurately controlled, the efficiency of hot pressing can be improved, the yield rate of the product obtained by hot pressing can be greatly improved, and it has better promotion value.

[0069] A preferred embodiment of a motor stator end cover hot pressing device of the present invention is described below in conjunction with the accompanying drawings.

[0070] See also Figure 1 and Figure 2 , the hot pressing equipment comprises:

[0071] Rack 1 provides support and installation space for other components.

[0072] The stator pressing mechanism 2 is arranged on the frame 1, and is used to carry the wound stator block 7 and drive the stator block 7 to perform lifting movement;

[0073] The end cover clamping mechanism 3 is arranged on the top of the stator press-fitting mechanism 2 and is used for clamping the stator end cover which is press-fitted with the stator block 7 .

[0074] The traditional hot pressing method is to clamp the stator block with a jig, and then drive the stator end cover toward the clamped stator block for hot pressing. Because the traditional hot pressing method needs to heat the stator blocks one by one, such a hot pressing method is required. Different from the traditional hot pressing method, the hot pressing device clamps the stator end cover with the end cover clamping mechanism 3, and then drives the stator block 7 placed thereon toward the clamped stator end cover for hot pressing through the stator pressing mechanism 2, because the hot pressing device heats the stator end cover.

[0075] The pre-press-fitting heating mechanism 4 is arranged beside the stator press-fitting mechanism 2 and is used to heat the stator end cover clamped in the end cover clamping mechanism 3 by adopting a high-frequency heating method.

[0076] The high-frequency heating power supply 5 is arranged beside the pre-press-fitting heating mechanism 4 and is electrically connected to the pre-press-fitting heating mechanism 4 for energizing the pre-press-fitting heating mechanism 4 .

[0077] The process switching mechanism 6 is arranged on the frame 1 and is transmission-connected with the end cover clamping mechanism 3, and is used to drive the end cover clamping mechanism 3 to move between the stator pressing mechanism 2 and the pre-pressing heating mechanism 4 to switch the process. It can be understood that the process switching mechanism 6 can also move the stator pressing mechanism 2 to the loading and unloading stations to put in the stator end cover to be pressed and take out the stator end cover after pressing.

[0078] See also Figures 7 to 9 Specifically, the stator press-fitting mechanism 2 includes:

[0079] The stator press-fitting fixture table 21 is slidably connected to the frame 1 and is provided with a circle of mounting tables for mounting the stator blocks 7 , on which a plurality of wound stator blocks 7 can be placed.

[0080] The press-fitting driver 22 is fixed on the frame 1, located at the bottom of the stator press-fitting fixture table 21 and cooperates with the stator press-fitting fixture table 21 in transmission. The press-fitting driver 22 is used to drive the stator press-fitting fixture table 21 to move up and down. In the process of the press-fitting driver 22 controlling the stator press-fitting fixture table 21 to move up and down, when the end cover clamping mechanism 3 is moved to the top of the stator press-fitting mechanism 2 under the control of the process switching mechanism 6, the stator press-fitting mechanism 2 cooperates with the end cover clamping mechanism 3 to complete the press-fitting of the stator block 7 and the stator end cover. It can be understood that in the above process, the stator clamp in the end cover clamping mechanism 3 has been heated by the pre-press-fitting heating mechanism 4.

[0081] See also Figures 4 to 6 , the stator press-fitting mechanism 2 also includes:

[0082] The lifting plate 23 is fixed to the bottom end of the stator press-fitting fixture 21 , is located between the stator press-fitting fixture 21 and the press-fitting driver 22 , and is in driving cooperation with the output end of the press-fitting driver 22 .

[0083] The pressure sensor 24 is disposed on the top boost plate 23 .

[0084] The stator material sensor 25 is arranged on the frame 1 and is located beside the stator press-fitting fixture table 21 .

[0085] The setting of the top-lifting plate 23 is equivalent to the press-fitting driver 22 acting on the top-lifting plate 23 when working, and then by pushing the top-lifting plate 23 to move up and down, the stator press-fitting fixture table 21 fixedly connected to the top-lifting plate 23 is synchronously lifted and lowered, so that the hot pressing process between the stator block 7 and the stator end cover is more stable. The role of the pressure sensor 24 and the stator material sensor 25 is to detect whether the stator block 7 is placed on the loading platform of the stator press-fitting fixture table 21, that is, through the dual feedback of the pressure sensor 24 and the stator material sensor 25, the quality of the press-fitting process is grasped and quality control is performed.

[0086] See also Figure 3 , the process switching mechanism 6 includes:

[0087] The displacement driver 61 is arranged on the frame 1. Specifically, in this embodiment, the displacement driver 61 is installed on the workbench 11 of the frame 1.

[0088] The mounting plate 62 is drivingly connected to the output end of the displacement driver 61 , an end cover clamping mechanism 3 is provided on the mounting plate 62 , and a first guide rail 12 slidably matched with the mounting plate 62 is provided on the workbench 11 .

[0089] Start the displacement driver 61. When working, the displacement driver 61 will drive the mounting plate 62 to slide horizontally. The end cover clamping mechanism 3 is installed on the mounting plate 62. Therefore, the end cover clamping mechanism 3 and the stator end cover clamped by the end cover clamping mechanism 3 can slide horizontally between the pre-pressing heating mechanism 4 and the stator pressing mechanism 2 to switch the process. Specifically, when the stator block 7 and the stator end cover are hot-pressed, the stator end cover is first clamped and held by the end cover clamping mechanism 3, and then the end cover clamping mechanism 3 is moved to the pre-pressing heating mechanism 4 by the process switching mechanism 6, and the high-frequency heating power supply 5 is started. The pre-pressing heating mechanism 4 heats the stator end cover clamped in the end cover clamping mechanism 3 by high-frequency heating. After the stator end cover is heated to a specified temperature, the process switching mechanism 6 moves the end cover clamping mechanism 3 and the heated stator end cover to the stator pressing mechanism 2, and the stator pressing mechanism 2 cooperates with the end cover clamping mechanism 3 to complete the hot pressing of the stator and the stator end cover.

[0090] See also Figures 7 to 9 Specifically, the end cover clamping mechanism 3 includes:

[0091] The clamping base 33 is fixed on the mounting plate 62 .

[0092] The end cover clamping fixture 31 is arranged on the clamping base 33 and is used to clamp the stator end cover which is press-fitted with the stator block 7 .

[0093] The condensation water path 32 is disposed on the end cover clamping fixture 31 and is used to cool the stator end cover clamped on the end cover clamping fixture 31 . The condensation water path 32 includes a condensation water inlet end 321 and a condensation water outlet end 322 .

[0094] The setting of the condensation water channel 32 can keep the stator end cover in the end cover clamping fixture 31 at a constant temperature, realize accurate control of the temperature during the press-fitting of the motor stator, meet the requirements of hot pressing, and better perform hot pressing between the stator and the stator end cover.

[0095] The end cap clamping mechanism 3 also includes:

[0096] A clamping adjustment driver 34 is provided on the clamping base 33;

[0097] The sliding platform 35 is slidably connected to the clamping base 33, on which the end cap clamping fixture 31 is fixed, and the sliding platform 35 is transmission-matched with the output end of the clamping adjustment driver 34. Specifically, in this embodiment, the clamping base 33 is provided with a second guide rail 331 that is slidably matched with the sliding platform 35.

[0098] The function of the clamping adjustment driver 34 is to control the position of the end cover clamping fixture 31 for fine adjustment. Such a setting can better clamp and hold the stator end cover.

[0099] The end cover material sensor 36 is arranged on the frame 1 and is located beside the end cover clamping fixture 31 .

[0100] In this embodiment, the stator material presence sensor 25 and the end cover material presence sensor 36 may be photoelectric sensors.

[0101] See also Figure 4 Specifically, the pre-pressing heating mechanism 4 includes:

[0102] The coil support platform 42 is slidably connected to the frame 1 .

[0103] The high-frequency heating coil 41 is mounted on a coil support 42 and is electrically connected to a high-frequency heating power source 5 .

[0104] The lifting driver 43 is arranged on the frame 1 and cooperates with the coil support platform 42 to drive the coil support platform 42 and the high-frequency heating coil 41 to move up and down.

[0105] The temperature sensor 44 is arranged on the frame 1 and is located beside the high-frequency heating coil 41. The temperature sensor 44 is used to measure the temperature of the stator end cover in real time. After the stator end cover is heated to the specified temperature, the process switching mechanism 6 moves the end cover clamping mechanism 3 and the heated stator end cover to the stator pressing mechanism 2. The stator pressing mechanism 2 cooperates with the end cover clamping mechanism 3 to complete the thermal pressing of the stator and the stator end cover.

[0106] Under normal conditions, the lifting driver 43 drives the coil support platform 42 and the high-frequency heating coil 41 to descend. When the stator end cover needs to be heated, the lifting driver 43 drives the coil support platform 42 and the high-frequency heating coil 41 to rise, so that the end cover clamping fixture 31 can be in the heating area of ​​the high-frequency heating coil 41. After starting the high-frequency heating power supply 5, the high-frequency heating power supply 5 energizes the high-frequency heating coil 41 during operation, so that an induced magnetic field is generated in the high-frequency heating coil 41. When the end cover clamping mechanism 3 moves to the high-frequency heating coil 41, the stator end cover clamped and held in the end cover clamping fixture 31 will generate eddy currents and then heat and expand.

[0107] See also Figures 7 to 9 , and also includes a centering tool 8, which is used to adjust the position of the stator block 7 and the stator end cover before the stator block 7 and the stator end cover are heat-pressed together, so that the stator block 7 is distributed along the axial circumference of the stator end cover, and the centering tool 8 includes;

[0108] The self-aligning press-fitting boss 81 cooperates with the stator end cover to locate the position of the stator end cover;

[0109] The centering and positioning platform 82 is coaxially fixed on the centering and pressing boss 81. The connection between the centering and positioning platform 82 and the centering and pressing boss 81 is used to adjust the position of the stator block 7 so that the stator block 7 is distributed along the axis of the stator end cover. When the centering and positioning platform 82 is inserted into the stator pressing fixture 21, each stator block 7 placed on the loading platform on the stator pressing fixture 21 will be pushed to a position distributed along the axis of the stator end cover, and the position of the stator block 7 before pressing will be corrected to ensure the quality of the motor after pressing.
