Description

Technical Field

[0001] This invention relates to the field of press-fitting technology, specifically a press-fitting device for stator cores of motors used in new energy vehicles. Background Technology

[0002] Currently, the new energy vehicle industry is developing rapidly. As the core component of the drive system, the manufacturing process of the motor directly determines the vehicle's power performance, energy efficiency, and reliability. The pressing of the stator core and frame is a crucial step in motor assembly and plays a decisive role in the overall quality of the motor. The fit between the stator core and frame requires extremely high precision. Insufficient interference fit during pressing will lead to loosening and vibration during operation, causing excessive noise and energy loss; while excessive interference may cause the silicon steel sheets of the core to loosen or the frame to deform, and in severe cases, may even lead to motor burnout.

[0003] Currently, many factories assume that both the stator core and the frame are of good quality during the press-fitting process, and that the burrs on the outer wall of the stator core and the inner wall of the frame are within the set standard range. However, during the press-fitting process, some stator cores and frames still have clustered and unevenly distributed burrs. These burrs will affect the press-fitting quality of the stator core and frame. We need to locate and clean these burrs. At the same time, we need to set up a pressure regulating device for pressing the stator core to maintain a stable speed when pressing the stator core into the frame, avoiding pressing too fast or too slow, which would affect the quality and efficiency of the press-fitting. Summary of the Invention

[0004] The purpose of this invention is to provide a stator core pressing device for new energy vehicle motors to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The pressing device includes a worktable, a hydraulic module, a clamping slide, a clamping module, a burr detection module, a burr cleaning module, and a speed control module. The hydraulic module is rotatably connected to the worktable, the clamping slide is slidably connected to the worktable, the clamping module is slidably connected to the clamping slide, the burr detection module is slidably connected to the worktable, the burr detection module is fixedly connected to the clamping slide, the burr detection module and the burr cleaning module are signal connected, the burr cleaning module and the hydraulic module are slidably connected, the speed control module and the hydraulic module are fixedly connected, and the speed control module and the hydraulic module are signal connected.

[0007] The pressing device is equipped with a controller, which receives signals from the burr detection module and the speed control module, and controls the operation of the hydraulic module, clamping slide, clamping module, burr detection module, burr removal module, and speed control module. The worktable is divided into upper and lower surfaces. The hydraulic module is located on the upper surface of the worktable, and the clamping slide is located on the lower surface, between the upper and lower surfaces. The clamping slide is used to transport the machine base before and after pressing. The clamping module is installed on the clamping slide. The stator core is positioned on the burr detection module by an external robotic arm. The clamping module clamps and positions the machine base and stator core. The burr detection module works with the clamping module to press the inner surface of the machine base. The outer wall of the stator core and the wall itself are divided into multiple vertical gap areas. An external air source is introduced into the burr detection module, which monitors the gas flow rate. If the flow rate value detected in a certain gap area is lower than the set value, it indicates that there are many or large burrs in that area. The clamping module releases the stator core and the frame, and the burr removal module locates and removes the burrs on the inner wall of the frame and the outer wall of the stator core in that area. After removal, the hydraulic module is activated to press the stator core into the frame. During the pressing process, the speed control module controls the output power of the hydraulic module to maintain a stable pressing rate of the stator core into the frame, ensuring pressing quality and efficiency.

[0008] Furthermore, the hydraulic module includes an electric rotating column and a hydraulic cylinder. The electric rotating column is rotatably connected to the worktable. The hydraulic cylinder is located at the top of the electric rotating column. The output end of the hydraulic cylinder is hinged to the speed control module. The burr removal module is located at the top of the electric rotating column. The burr removal module and the electric rotating column are slidably connected. The hydraulic cylinder and the speed control module are signal connected. The speed control module and the electric rotating column are fixedly connected.

[0009] The electric rotating column is installed on the upper surface of the workbench. By rotating the electric rotating column, the hydraulic cylinder and the burr removal module can be switched. The hydraulic cylinder is responsible for pressing the stator core.

[0010] Furthermore, the clamping module includes a stator core clamping cylinder, a stator core clamping plate, a base clamping cylinder, a base clamping push rod, and a base clamping insert plate. The stator core clamping cylinder is fixedly connected to the worktable. Multiple stator core clamping cylinders and multiple stator core clamping plates are provided. The multiple stator core clamping cylinders and multiple stator core clamping plates are fixedly connected in a one-to-one correspondence. The base clamping cylinder is fixedly connected to the clamping slide. The output end of the base clamping cylinder is hinged to one end of the base clamping push rod, and the other end of the base clamping push rod is hinged to the base clamping insert plate. The base clamping insert plate and the clamping slide are slidably connected.

[0011] When the base clamping cylinder is activated, the output end of the base clamping cylinder pulls down the base clamping push rod, which in turn pushes the base clamping insert plate. The base clamping insert plate clamps and positions the base. Simultaneously, multiple stator core clamping cylinders are activated, pushing the stator core clamping plate to position and clamp the stator core.

[0012] Furthermore, when multiple stator core clamping plates clamp the stator core, adjacent stator core clamping plates are in close contact with each other, and there is a gap between each stator core clamping plate and the outer wall of the stator core, with the gaps between each stator core clamping plate and the outer wall of the stator core being mutually separated.

[0013] Each stator core clamping plate is also equipped with a connection port at its upper end. External air enters the spaced gaps through the connection port. The gaps between each stator core clamping plate and the outer wall of the stator core are separated from each other, which can more accurately locate the area where the burrs are on the outer wall of the stator core.

[0014] Furthermore, the number of clamping plates on the machine base is equal to the number of clamping plates on the stator core. After the clamping plates clamp the machine base, there is a gap between the burr detection module and the machine base. The clamping plates separate the gap between the burr detection module and the machine base. The gaps between the burr detection module, the clamping plates, and the machine base, as well as the gaps between the clamping plates and the outer wall of the stator core, are connected in a one-to-one correspondence.

[0015] The burr detection module, the base clamping plate, the gap between the bases, and the gap between the stator core clamping plate and the outer wall of the stator core are connected in a corresponding manner. The airflow passes through the burr detection module, the base clamping plate, the gap between the bases, and the gap between the stator core clamping plate and the outer wall of the stator core in sequence, and then enters the burr detection module. The burr detection module monitors the flow rate of the passing gas, so as to simultaneously detect burrs on the outer wall of the stator core and the inner wall of the base along the path.

[0016] Furthermore, the burr detection module includes detection baffles, gas flow monitoring devices, and return springs. The number of detection baffles is the same as the number of stator core clamping plates. The detection baffles pass through the worktable and are slidably connected to it. One end of the return spring is fixedly connected to the bottom end of the worktable, and the other end of the return spring is fixedly connected to the bottom end of the detection baffle. The number of gas flow monitoring devices is the same as the number of detection baffles. The gas flow monitoring devices are fixedly connected to the bottom ends of the detection baffles one by one. The gas flow monitoring devices are slidably connected to the worktable and are signal-connected to the burr cleaning module.

[0017] A gap exists between the detection baffle and the inner wall of the base. The base clamping plate separates this gap, with the separation position matching the separation position between each stator core clamping plate and the outer wall of the stator core. Furthermore, the gaps between the base clamping plate, the detection baffle, and the inner wall of the base are vertically connected to the gaps between the stator core clamping plates and the outer walls of the stator core. The airflow sequentially passes through the detection baffle, the gap between the base clamping plate and the base, and the gap between the stator core clamping plates and the outer walls of the stator core, before entering the gas flow monitoring device. The gas flow monitoring device monitors the passing gas... The gas flow rate is monitored to simultaneously detect burrs on the outer wall of the stator core and the inner wall of the machine base along the path. If the detected gas flow rate is lower than the preset value, the gas flow rate monitoring device sends a signal to the controller. The controller receives the signal and controls the clamping module to release the stator core and the machine base. The electric rotating column rotates, moving the burr cleaning module directly above the stator core. The burr cleaning module is then activated to clean the outer wall of the stator core and the inner wall of the machine base in the corresponding area. When the hydraulic cylinder presses the stator core, the stator core presses down on the detection baffle, and the return spring is compressed to ensure that the detection baffle does not affect the pressing of the stator core.

[0018] Furthermore, the burr removal module includes cleaning cylinders and cleaning scrapers. The number of cleaning cylinders is the same as the number of stator core clamping plates. The cleaning cylinders are fixedly connected to the electric rotating column, and the cleaning cylinders are located at the top of the electric rotating column. The number of cleaning scrapers is the same as the number of cleaning cylinders. The output end of the cleaning cylinder and the top of the cleaning scraper are fixedly connected in a one-to-one correspondence.

[0019] The controller associates the gas flow monitoring device with its corresponding vertical cleaning cylinder. When the gas flow detected by one or more gas flow monitoring devices is lower than the preset value, the controller receives a signal from one or more gas flow monitoring devices. The controller then controls the clamping module to release the stator core and the machine base, the electric rotating column rotates, and the vertical cleaning cylinder of one or more gas flow monitoring devices is activated, pushing the cleaning scraper to clean the outer wall of the stator core and the inner wall of the machine base in the corresponding area.

[0020] Furthermore, the speed control module includes a speed control mounting bracket, a speed control cylinder, a speed control slider, a speed control rod, a pressure switch, and a pressure reducing switch. The speed control mounting bracket is installed inside the electric rotating column and is fixedly connected to the electric rotating column. The speed control cylinder is fixedly connected to the electric rotating column. The output end of the speed control cylinder is hinged to one end of the speed control rod, and the other end of the speed control rod is hinged to the output end of the hydraulic cylinder. The speed control rod and the speed control slider are rotatably connected, and the speed control slider and the speed control mounting bracket are slidably connected. The pressure switch and the speed control slider are fixedly connected, and the pressure switch is located on one side of the speed control rod. The pressure reducing switch and the speed control slider are fixedly connected, and the pressure reducing switch is located on the other side of the speed control rod. The speed control rod abuts against the pressure switch and the pressure reducing switch on both sides respectively.

[0021] Both the pressure-increasing and pressure-reducing switches are linear switches. When the pressure-increasing switch is pressed, the power of the hydraulic cylinder increases; when the pressure-reducing switch is pressed, the power of the hydraulic cylinder decreases. When the hydraulic cylinder presses the stator core, the speed-regulating cylinder starts simultaneously. The speed-regulating cylinder pulls down one end of the speed-regulating rod, the speed of which is set by the operator via the controller. The output end of the hydraulic cylinder pulls down the other end of the speed-regulating rod. When the output end of the hydraulic cylinder pulls the speed-regulating rod faster than the speed-regulating cylinder, the speed-regulating rod rotates at the speed-regulating slider. The rotating speed-regulating rod presses down the pressure-reducing switch, reducing the power of the hydraulic cylinder and decreasing the pressure of pressing the stator core until the speed-regulating rod is horizontal, preventing excessive pressing speed from affecting product quality. When the output end of the hydraulic cylinder pulls the speed-regulating rod slower than the speed-regulating cylinder, the speed-regulating rod rotates at the speed-regulating slider. The rotating speed-regulating rod presses down the pressure-increasing switch, increasing the power of the hydraulic cylinder and increasing the pressure of pressing the stator core until the speed-regulating rod is horizontal, ensuring the pressing speed.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The burr detection module of the present invention, together with the clamping module, divides the inner wall of the machine base and the outer wall of the stator core into multiple vertical gap regions. An external air source is introduced into the burr detection module, which monitors the gas flow rate through the burr detection module and determines whether there are a large number of burrs agglomerated on the inner wall of the machine base and the outer wall of the stator core in each gap region.

[0024] 3. In this invention, when the hydraulic cylinder presses the stator core, the speed-regulating cylinder is simultaneously activated. The speed-regulating cylinder pulls down one end of the speed-regulating rod, the pulling speed of which is set by the operator via a controller. The output end of the hydraulic cylinder pulls down the other end of the speed-regulating rod. When the output end of the hydraulic cylinder pulls the speed-regulating rod faster than the speed-regulating cylinder pulls the speed-regulating rod, the speed-regulating rod rotates at the speed-regulating slider. The rotating speed-regulating rod depresses the pressure-reducing switch, reducing the power of the hydraulic cylinder and decreasing the pressure of pressing the stator core until the speed-regulating rod is horizontal, preventing excessive pressing speed from affecting product quality. When the output end of the hydraulic cylinder pulls the speed-regulating rod slower than the speed-regulating cylinder pulls the speed-regulating rod, the speed-regulating rod rotates at the speed-regulating slider. The rotating speed-regulating rod depresses the pressure-increasing switch, increasing the power of the hydraulic cylinder and increasing the pressure of pressing the stator core until the speed-regulating rod is horizontal, ensuring the pressing rate.

[0036] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example: Figure 1 - Figure 10 As shown, this invention provides a technical solution for a stator core pressing device for new energy vehicle motors:

[0038] like Figure 1 and Figure 2 As shown, the pressing device includes a worktable 1, a hydraulic module 2, a clamping slide 3, a clamping module 4, a burr detection module 5, a burr cleaning module 6, and a speed control module 7. The hydraulic module 2 is rotatably connected to the worktable 1, the clamping slide 3 is slidably connected to the worktable 1, the clamping module 4 is slidably connected to the clamping slide 3, the burr detection module 5 is slidably connected to the worktable 1, the burr detection module 5 is fixedly connected to the clamping slide 3, the burr detection module 5 is signal-connected to the burr cleaning module 6, the burr cleaning module 6 is slidably connected to the hydraulic module 2, the speed control module 7 is fixedly connected to the hydraulic module 2, and the speed control module 7 is signal-connected to the hydraulic module 2.

[0039] The pressing device is equipped with a controller, which receives signals from the burr detection module 5 and the speed control module 7, and controls the operation of the hydraulic module 2, clamping slide 3, clamping module 4, burr detection module 5, burr removal module 6, and speed control module 7. The worktable 1 is divided into upper and lower surfaces. The hydraulic module 2 is located on the upper surface of the worktable 1, and the clamping slide 3 is located on the lower surface of the worktable 1, between the upper and lower surfaces. The clamping slide 3 is used to transport the machine base before and after pressing. The clamping module 4 is installed on the clamping slide 3. The stator core is positioned on the burr detection module 5 by an external robotic arm. The clamping module 4 clamps and positions the machine base and stator core. The burr detection module 5 works in conjunction with the clamping module. Block 4 divides the inner wall of the machine base and the outer wall of the stator core into multiple vertical gap areas. An external air source is introduced into the burr detection module 5, which monitors the gas flow rate. If the flow rate value detected in a certain corresponding gap area is lower than the set value, it indicates that there are many or large burrs in that area. The clamping module 4 releases the stator core and the machine base, and the burr removal module 6 locates and removes the burrs on the inner wall of the machine base and the outer wall of the stator core in that area. After removal, the hydraulic module 2 is activated to press the stator core into the machine base. During the pressing process, the speed control module 7 controls the output power of the hydraulic module 2 to maintain a stable pressing rate of the stator core into the machine base, ensuring pressing quality and pressing efficiency.

[0040] like Figure 2 and Figure 3 As shown, the hydraulic module 2 includes an electric rotating column 21 and a hydraulic cylinder 22. The electric rotating column 21 is rotatably connected to the worktable 1. The hydraulic cylinder 22 is located at the top of the electric rotating column 21. The output end of the hydraulic cylinder 22 is hinged to the speed control module 7. The burr removal module 6 is located at the top of the electric rotating column 21. The burr removal module 6 is slidably connected to the electric rotating column 21. The hydraulic cylinder 22 is signal-connected to the speed control module 7. The speed control module 7 is fixedly connected to the electric rotating column 21.

[0041] The electric rotating column 21 is installed on the upper surface of the workbench 1. By rotating the electric rotating column 21, the hydraulic cylinder 22 and the burr removal module 6 can be switched. The hydraulic cylinder 22 is responsible for pressing the stator core.

[0042] like Figures 2 to 5As shown, the clamping module 4 includes a stator core clamping cylinder 41, a stator core clamping plate 42, a base clamping cylinder 43, a base clamping push rod 44, and a base clamping insert plate 45. The stator core clamping cylinder 41 is fixedly connected to the worktable 1. Multiple stator core clamping cylinders 41 and multiple stator core clamping plates 42 are provided. Multiple stator core clamping cylinders 41 and multiple stator core clamping plates 42 are fixedly connected one-to-one. The base clamping cylinder 43 is fixedly connected to the clamping slide 3. The output end of the base clamping cylinder 43 is hinged to one end of the base clamping push rod 44, and the other end of the base clamping push rod 44 is hinged to the base clamping insert plate 45. The base clamping insert plate 45 and the clamping slide 3 are slidably connected.

[0043] When the base clamping cylinder 43 is activated, the output end of the base clamping cylinder 43 pulls down the base clamping push rod 44, the base clamping push rod 44 pushes the base clamping insert plate 45, and the base clamping insert plate 45 clamps and positions the base. At the same time, multiple stator core clamping cylinders 41 are activated, pushing the stator core clamping plate 42 to position and clamp the stator core.

[0044] like Figure 2 and Figure 10 As shown, when multiple stator core clamping plates 42 clamp the stator core, adjacent stator core clamping plates 42 are in close contact with each other, and there is a gap between each stator core clamping plate 42 and the outer wall of the stator core. The gaps between each stator core clamping plate 42 and the outer wall of the stator core are separated from each other.

[0045] Each stator core clamping plate 42 is also provided with a connection port at its upper end. An external air source enters the gaps between the plates through the connection port. The gaps between each stator core clamping plate 42 and the outer wall of the stator core are separated from each other, which can more accurately locate the area where the burrs are on the outer wall of the stator core.

[0046] like Figure 3 and Figure 6 As shown, the number of base clamping plates 45 is equal to the number of stator core clamping plates 42. After the base clamping plates 45 clamp the base, there is a gap between the burr detection module 5 and the base. The base clamping plates 45 separate the gap between the burr detection module 5 and the base. The gap between the burr detection module 5, the base clamping plates 45, and the base, and the gap between the stator core clamping plates 42 and the outer wall of the stator core are connected one by one.

[0047] The burr detection module 5, the base clamping plate 45, the gap between the bases, and the gap between the stator core clamping plate 42 and the outer wall of the stator core are connected in a corresponding manner. The airflow passes through the burr detection module 5, the base clamping plate 45, the gap between the bases, and the gap between the stator core clamping plate 42 and the outer wall of the stator core in sequence, and then enters the burr detection module 5. The burr detection module 5 monitors the flow rate of the passing gas, so as to simultaneously detect burrs on the outer wall of the stator core and the inner wall of the base along the path.

[0048] like Figure 3 and Figure 9 As shown, the burr detection module 5 includes a detection baffle 51, a gas flow monitoring device 52, and a reset spring 53. The number of detection baffles 51 is the same as the number of stator core clamping plates 42. The detection baffles 51 pass through the worktable 1 and are slidably connected to the worktable 1. One end of the reset spring 53 is fixedly connected to the bottom end of the worktable 1, and the other end of the reset spring 53 is fixedly connected to the bottom end of the detection baffle 51. The number of gas flow monitoring devices 52 is the same as the number of detection baffles 51. The bottom ends of the gas flow monitoring devices 52 and the detection baffles 51 are fixedly connected one-to-one. The gas flow monitoring devices 52 are slidably connected to the worktable 1 and are signal-connected to the burr cleaning module 6.

[0049] A gap is left between the detection baffle 51 and the inner wall of the base. The base clamping plate 45 separates the gap between the detection baffle 51 and the inner wall of the base. The separation position is the same as the separation position between each stator core clamping plate 42 and the outer wall of the stator core. The gaps between the base clamping plate 45, the detection baffle 51 and the inner wall of the base, and the gaps between the stator core clamping plate 42 and the outer wall of the stator core are vertically connected. The airflow passes sequentially through the gaps between the detection baffle 51, the base clamping plate 45 and the base, and the stator core clamping plate 42 and the outer wall of the stator core, and then enters the gas flow monitoring device 52. The gas flow monitoring device 52 monitors the flow. The gas flow rate is monitored to simultaneously detect burrs on the outer wall of the stator core and the inner wall of the machine base along the path. If the detected gas flow rate is lower than the preset value, the gas flow monitoring device 52 sends a signal to the controller. The controller receives the signal and controls the clamping module 4 to release the stator core and the machine base. The electric rotating column 21 rotates, moving the burr cleaning module 6 directly above the stator core. The burr cleaning module 6 is activated to clean the outer wall of the stator core and the inner wall of the machine base in the corresponding area. When the hydraulic cylinder 22 presses the stator core, the stator core presses down on the detection baffle 51, and the reset spring 53 is compressed to ensure that the detection baffle 51 does not affect the pressing of the stator core.

[0050] like Figure 1As shown, the burr removal module 6 includes a cleaning cylinder 61 and a cleaning scraper 62. The number of cleaning cylinders 61 is the same as the number of stator core clamping plates 42. The cleaning cylinders 61 are fixedly connected to the electric rotating column 21, and the cleaning cylinders 61 are located at the top of the electric rotating column 21. The number of cleaning scrapers 62 is the same as the number of cleaning cylinders 61. The output end of the cleaning cylinder 61 and the top end of the cleaning scraper 62 are fixedly connected one-to-one.

[0051] The controller associates the gas flow monitoring device 52 with its corresponding vertical cleaning cylinder 61. When the gas flow detected by one or more gas flow monitoring devices 52 is lower than the preset value, the controller receives a signal from one or more gas flow monitoring devices 52. The controller then controls the clamping module 4 to release the stator core and the machine base, the electric rotating column 21 rotates, and the cleaning cylinder 61 of one or more gas flow monitoring devices 52 in the vertical direction is activated, pushing the cleaning scraper 62 to clean the outer wall of the stator core and the inner wall of the machine base in the corresponding area.

[0052] like Figure 3 , Figure 7 and Figure 8 As shown, the speed control module 7 includes a speed control mounting bracket 71, a speed control cylinder 72, a speed control slider 73, a speed control rod 74, a pressure switch 75, and a pressure reduction switch 76. The speed control mounting bracket 71 is installed inside the electric rotating column 21 and is fixedly connected to the electric rotating column 21. The speed control cylinder 72 is fixedly connected to the electric rotating column 21. The output end of the speed control cylinder 72 is hinged to one end of the speed control rod 74, and the other end of the speed control rod 74 is hinged to the output end of the hydraulic cylinder 22. The speed control rod 74 and the speed control slider 73 are rotatably connected, and the speed control slider 73 is slidably connected to the speed control mounting bracket 71. The pressure switch 75 is fixedly connected to the speed control slider 73 and is located on one side of the speed control rod 74. The pressure reduction switch 76 is fixedly connected to the speed control slider 73 and is located on the other side of the speed control rod 74. The speed control rod 74 abuts against the pressure switches 75 and 76 on both sides respectively.

[0053] Both the pressure-increasing switch 75 and the pressure-reducing switch 76 are linear switches. When the pressure-increasing switch 75 is pressed, the power of the hydraulic cylinder 22 increases; when the pressure-reducing switch 76 is pressed, the power of the hydraulic cylinder 22 decreases. When the hydraulic cylinder 22 presses the stator core, the speed-regulating cylinder 72 starts simultaneously. The speed-regulating cylinder 72 pulls down one end of the speed-regulating lever 74, and the pulling speed is set by the operator via the controller. The output end of the hydraulic cylinder 22 pulls down the other end of the speed-regulating lever 74. When the speed at which the output end of the hydraulic cylinder 22 pulls the speed-regulating lever 74 is faster than the speed at which the speed-regulating cylinder 72 pulls the speed-regulating lever 74, the speed-regulating lever... The speed control lever 74 rotates at the speed control slider 73. The rotating speed control lever 74 presses down the pressure reducing switch 76, reducing the power of the hydraulic cylinder 22 and the pressure of pressing the stator core until the speed control lever 74 is horizontal, preventing the pressing speed from being too fast and affecting product quality. When the output end of the hydraulic cylinder 22 pulls the speed control lever 74 at a slower speed than the speed control cylinder 72 pulls the speed control lever 74, the speed control lever 74 rotates at the speed control slider 73. The rotating speed control lever 74 presses down the pressure increasing switch 75, increasing the power of the hydraulic cylinder 22 and the pressure of pressing the stator core until the speed control lever 74 is horizontal, ensuring the pressing speed.

[0054] The working principle of this invention: The pressing device is equipped with a controller, which receives signals from the burr detection module 5 and the speed control module 7, and controls the operation of the hydraulic module 2, clamping slide 3, clamping module 4, burr detection module 5, burr removal module 6, and speed control module 7. The worktable 1 is divided into upper and lower surfaces. The hydraulic module 2 is located on the upper surface of the worktable 1, and the clamping slide 3 is located on the lower surface of the worktable 1, between the upper and lower surfaces. The clamping slide 3 is used to transport the machine base before and after pressing. The clamping module 4 is installed on the clamping slide 3. The stator core is positioned on the burr detection module 5 by an external robotic arm. The clamping module 4 clamps and positions the machine base and the stator core. The burr detection module 5 is equipped with... The clamping module 4 divides the inner wall of the machine base and the outer wall of the stator core into multiple vertical gap areas. An external air source is introduced into the burr detection module 5, which monitors the gas flow rate. If the flow rate value detected in a certain corresponding gap area is lower than the set value, it indicates that there are many or large burrs in that area. The clamping module 4 releases the stator core and the machine base. The burr removal module 6 locates and removes the burrs on the inner wall of the machine base and the outer wall of the stator core in that area. After removal, the hydraulic module 2 is activated to press the stator core into the machine base. During the pressing process, the speed control module 7 controls the output power of the hydraulic module 2 to maintain a stable pressing rate of the stator core into the machine base, ensuring pressing quality and pressing efficiency.
