Description

Technical Field

[0001] This application relates to the field of stator insulation end plate installation technology, and in particular to a pressing device for insulation end plates. Background Technology

[0002] The stator is the stationary part of an electric motor or generator, and its main function is to generate a rotating magnetic field. In a generator, the stator windings cut the magnetic lines of force generated by the rotor, thereby producing an electric current; in an electric motor, the rotating magnetic field generated by the stator drives the rotor to rotate. Insulating end plates are parts that prevent the ends of the stator from coming into contact with other components and causing a short circuit. They protect the insulation of the stator coils and prevent damage to the coil insulation caused by vibration, impact, or scratches from foreign objects.

[0003] When installing the insulating end plate on the stator, the insulating end plate and the stator are in clearance fit. The existing installation method usually uses manual installation of the insulating end plate. This installation method relies more on the operator's skill level. In addition, the edge of the insulating end plate is relatively thin. When the insulating end plate is inserted into the stator by hand, the edge is easy to deform. It is difficult to align the insulating end plate with the stator slot by hand, making the installation difficult and the operation quite challenging. Utility Model Content

[0032] When installing the insulating end plate on the stator, the insulating end plate and the stator are in clearance fit. The existing installation method usually uses manual installation of the insulating end plate. This installation method relies more on the operator's skill level. In addition, the edge of the insulating end plate is relatively thin. When the insulating end plate is inserted into the stator by hand, the edge is easy to deform. It is difficult to align the insulating end plate with the stator slot by hand, making the installation difficult and the operation quite challenging.

[0033] In view of this, this application proposes a pressing device for insulating end plates.

[0034] In the embodiments of this application, reference is made to Figures 1 to 6 The aforementioned pressing device for insulating end plates includes a pressing assembly 1 and a controller. The pressing assembly 1 includes a base plate 110. A first positioning assembly 120 and a second positioning assembly 130 are provided on the base plate 110. The first positioning assembly 120 is used for the installation and positioning of the front insulating end plate 7, and the second positioning assembly 130 is used for the installation and positioning of the rear insulating end plate 9 and the stator 8. A moving assembly 180 is provided between the first positioning assembly 120 and the base plate 110. The moving assembly 180 is used to drive the first positioning assembly 120 to move towards the second positioning assembly 130, so that the front insulating end plate 7 moves closer to the stator 8, and the front insulating end plate 7 and the rear insulating end plate 9 are pressed onto the two ends of the stator 8 by compression.

[0035] Specifically, the first positioning component 120 and the second positioning component 130 are used to position the front insulating end plate 7, the rear insulating end plate 9 and the stator 8 respectively, ensuring the accuracy of the pressing process and realizing the precise positioning and installation of the front and rear insulating end plates 9 and the stator 8.

[0036] refer to Figure 2 and Figure 3 A first sensor 140 is provided on the first positioning component 120, and a second sensor 150 is provided on the second positioning component 130. The first sensor 140 is used to sense whether the front insulating end plate 7 is installed in place, and the second sensor 150 is used to sense whether the rear insulating end plate 9 is installed in place. The moving component 180, the first sensor 140, and the second sensor 150 are all electrically connected to the controller, which can ensure that the front insulating end plate 7 and the rear insulating end plate 9 are in the correct position, improve the reliability and safety of press fitting, and avoid the insulation end plate being squeezed and deformed due to improper installation of the front insulating end plate 7 and the rear insulating end plate 9.

[0037] refer to Figure 2 and Figure 3 A first stripping component 160 is provided on the first positioning component 120. The first stripping component 160 is used to remove the front insulating end plate 7 from the first positioning component 120. A second stripping component 170 is provided on the second positioning component 130. The second stripping component 170 is used to remove the rear insulating end plate 9 and the stator 8 from the second positioning component 130. This facilitates the removal of the insulating end plate and the stator 8 from the positioning component after pressing, thereby improving production efficiency, reducing manual intervention, and reducing labor intensity.

[0038] refer to Figure 2 and Figure 3 The first positioning component 120 includes a first mounting plate 121, which is mounted on the movable component 180. The first mounting plate 121 has a mounting hole 122, and a first positioning member 123 is slidably installed in the mounting hole 122. The first positioning member 123 is a cylindrical structure with a cross-sectional shape consistent with that of the front insulating end plate 7. The shape of the mounting hole 122 is consistent with that of the cross-sectional shape of the first positioning member 123. The first positioning member 123 is used to fit and position the front insulating end plate 7. That is, during installation, the front insulating end plate 7 is fitted on the outside of the first positioning member 123. By matching the shape of the first positioning member 123 with that of the front insulating end plate 7, the positioning of the front insulating end plate 7 is achieved by fitting. This can accurately fit and position the front insulating end plate 7, ensuring the positional accuracy of the front insulating end plate 7 during the pressing process.

[0039] refer to Figure 2 and Figure 3The first unloading assembly 160 includes a baffle 161. The baffle 161 is disposed on the side of the first mounting plate 121 away from the second positioning assembly 130. The baffle 161 is fixedly connected to the first mounting plate 121 by a plurality of connecting rods 162. A guide post 163 is disposed between the baffle 161 and the first positioning member 123. The first end of the guide post 163 is fixedly connected to the first positioning member 123, and the second end of the guide post 163 passes through the baffle 161 and is provided with a guide post cap 164. The diameter of the guide post cap 164 is larger than the diameter of the guide post 163. The guide post 163 is slidably connected to the baffle 161. A spring 165 is sleeved on the outside of the guide post 163. The two ends of the spring 165 are... Do not press against the first positioning member 123 and the baffle 161; during the process of the first positioning assembly 120 pressing the front insulating end plate 7 into the stator 8, the front insulating end plate 7 will first approach and contact the stator 8 under the drive of the first positioning member 123. The first positioning member 123 will counteract the force of the spring 165 and slide towards the baffle 161. As the first positioning assembly 120 continues to move, the first mounting plate 121 will press against one end of the front insulating end plate 7 and press the front insulating end plate 7 into the stator 8. Since the moving direction of the first positioning member 123 is opposite to the moving direction of the front insulating end plate 7, the front insulating end plate 7 will disengage from the first positioning member 123.

[0040] Specifically, in order to prevent the first positioning member 123 from dislodging from the mounting hole 122, a limiting block is provided between the first positioning member 123 and the baffle 161. The limiting block is fixedly installed on the baffle 161. When the first positioning member 123 moves to a certain position on the baffle 161, the baffle 161 will prevent the first positioning member 123 from continuing to move, thereby preventing the first positioning member 123 from dislodging from the mounting hole 122.

[0041] refer to Figure 2 and Figure 3 The first sensing element 140 includes a trigger switch 141, which is fixedly mounted on the baffle 161. A trigger rod 142 is disposed between the trigger switch 141 and the first mounting plate 121. The first end of the trigger rod 142 is connected to the trigger switch 141, and the second end of the trigger rod 142 extends to the side of the first positioning element 123 and passes through the first mounting plate 121. The trigger rod 142 is slidably connected to the first mounting plate 121 and is used to abut against the end face of the front insulating end plate 7. When the front insulating end plate 7 is fitted onto the first positioning element 123, it will push the trigger rod 142 to move toward the trigger switch 141, so that the trigger switch 141 can sense whether the front insulating end plate 7 is installed in place and transmit the signal that the front insulating end plate 7 is installed in place to the controller.

[0042] refer to Figure 3 and Figure 4The second positioning assembly 130 includes a second mounting plate 131, which is fixedly mounted on the base plate 110. A receiving groove 132 is formed on the end face of the second mounting plate 131 facing the first positioning assembly 120. The shape of the receiving groove 132 is consistent with the shape of one end of the rear insulating end plate 9, and the receiving groove 132 can accommodate the rear insulating end plate 9. A second positioning member 133 is disposed within the receiving groove 132. The first end of the second positioning member 133 is fixedly connected to the bottom surface of the receiving groove 132. The second positioning member 133 is used to mount the rear insulating end plate 9 and the stator 8, and also for positioning the rear insulating end plate 9. A positioning plate 134 is provided on one side facing the first positioning component 120. The positioning plate 134 is fixedly installed on the second mounting plate 131 by a connecting block. The positioning plate 134 has a positioning hole 135, which is sleeved on the outside of the second positioning component 133. A positioning notch 136 is provided on the side of the positioning hole 135. A positioning protrusion 801 is provided on the side of the stator 8. The positioning notch 136 is used to position the stator 8 through the positioning protrusion 801. The rear insulating end plate 9 is positioned by the second positioning component 133. The positioning plate 134 and the positioning notch 136 are used to position the stator 8, ensuring the installation accuracy of the rear insulating end plate 9 and the stator 8.

[0043] refer to Figure 3 The cross-sectional shape of the first end of the second positioning member 133 is consistent with the cross-sectional shape of the rear insulating end plate 9 and the stator 8. The second end of the second positioning member 133 is cylindrical, and the diameter of the second end of the second positioning member 133 is smaller than the diameter of the hole on the stator 8, so that the rear insulating end plate 9 and the stator 8 can be fitted onto the second positioning member 133.

[0044] refer to Figure 2 and Figure 3The second unloading assembly 170 includes a cylinder 171. The cylinder 171 is disposed on the side of the second mounting plate 131 facing away from the first positioning assembly 120.

A top block 174 is disposed between the third mounting plate 172 and the second mounting plate 131. The top block 174 is fixedly mounted on the telescopic rod of the cylinder 171. Multiple top rods 175 are fixedly mounted on the side of the top block 174 facing the first positioning assembly 120. The push rod 175 passes through the second mounting plate 131 and extends to the side of the second positioning member 133. The push rod 175 is slidably connected to the second mounting plate 131. The push rod 175 is used to abut against the end face of the rear insulating end plate 9. When the cylinder 171 is started, the telescopic rod of the cylinder 171 extends and moves the push rod 175 toward the first positioning assembly 120 through the push block 174, thereby pushing the rear insulating end plate 9 away from the second positioning member 133. The cylinder 171 drives the push rod 175, which can provide sufficient thrust to ensure that the rear insulating end plate 9 and the stator 8 are smoothly disengaged from the second positioning assembly 130. The operation is simple and highly automated.

[0045] refer to Figure 2 and Figure 3 The second sensing element 150 is an optical sensor, which is fixedly mounted on the second mounting plate 131. The optical sensor faces the second positioning element 133 and emits light. When the rear insulating end plate 9 is installed in place, the light is reflected or blocked by the rear insulating end plate 9. The optical sensor receives the corresponding signal and feeds it back to the controller. The optical sensor has the characteristics of non-contact detection, high detection accuracy, fast response speed, and can accurately detect whether the rear insulating end plate 9 is installed in place.

[0046] Specifically, a detection hole is provided on the second mounting plate 131 between the second sensor 150 and the receiving groove 132. The light from the second sensor can pass through the detection hole into the receiving groove 132 to facilitate detection of whether the insulating end plate 9 has entered the receiving groove 132.

[0047] refer to Figure 2 and Figure 3 The moving component 180 includes a sliding component and a driving component. The sliding component includes a guide rail 181 and a slider 182. The guide rail 181 is fixedly mounted on the base plate 110, and the slider 182 is slidably mounted on the guide rail 181. The first positioning component 120 is mounted on the slider 182, and the driving component is connected to the slider 182. The driving component is used to drive the slider 182. The combination of the sliding component and the driving component enables the first positioning component 120 to move smoothly and accurately. The cooperation between the guide rail 181 and the slider 182 ensures the straightness and stability of the movement.

[0048] Specifically, the drive component (existing technology) is preferably a pneumatic drive component, but it can also be an electric drive component or a hydraulic drive component.

[0049] refer to Figure 2 and Figure 3 The base plate 110 is mounted on the support box 2, which is supported on the ground by multiple support members 3. The drive assembly is located inside the support box 2. A protective cover 4 is also provided on the support box 2, covering the outside of the pressing assembly 1. The protective cover 4 has an opening on one side, and a light grating 5 and a control button 6 are provided at the opening. The light grating 5 and the control button 6 are electrically connected to the controller. The light grating 5 can sense whether anyone has entered the opening of the protective cover 4. If a human body or other object enters, the light grating 5 can feed the information back to the controller, which will then stop the machine, thereby protecting the operator's safety. The support box 2 and the support members 3 provide stable support for the pressing device, the protective cover 4 can protect the operator's safety and prevent accidents during the pressing process, and the light grating 5 and the control button 6 further improve the safety and convenience of operation.

[0050] This application's technical solution involves setting up a pressing assembly and a controller. The pressing assembly includes a base plate, on which a first positioning assembly and a second positioning assembly are mounted. The first positioning assembly is used for the installation and positioning of the front insulating end plate, and the second positioning assembly is used for the installation and positioning of the rear insulating end plate and the stator. A moving assembly is provided between the first positioning assembly and the base plate. The moving assembly drives the first positioning assembly to move towards the second positioning assembly, bringing the front insulating end plate closer to the stator. Through compression, the front and rear insulating end plates are pressed onto both ends of the stator. A first sensing element is provided on the first positioning assembly, and a second sensing element is provided on the second positioning assembly. The first sensing element is used to sense whether the front insulating end plate is installed. The second sensing element is used to detect whether the rear insulating end plate is installed in place, ensuring that the front and rear insulating end plates are in the correct positions and preventing deformation of the insulating end plates due to improper installation. This design uses the first and second positioning components to install and position the front and rear insulating end plates and the stator respectively. By moving the first and second positioning components closer together and pressing them, the front and rear insulating end plates can be pressed onto both ends of the stator. The pressing process is not affected by the operator's skill level and can quickly and accurately align the insulating end plates with the slots of the stator, thereby improving the pass rate and work efficiency of the pressing.
