Description

Technical Field

[0001] This invention relates to the field of motor parts processing technology, and in particular to a clamping device used in motor parts processing. Background Technology

[0002] In automotive motor manufacturing, the stator and rotor are essential components of the motor. They work together to convert electrical energy into mechanical energy through electromagnetic induction, which is crucial for the motor to achieve power output or generate electrical energy. They are also part of the overall manufacturing process. In actual production, they are pressed together with a clamping device to stack the qualified stamped laminations and form them into a single unit.

[0003] Existing clamping devices generally use manual feeding, placing the laminations one by one. After the number and height of the laminations meet the requirements, the clamping operation is then performed. However, due to the high precision alignment requirements of the laminations and the lack of precision in manual repetitive actions, it is easy for the laminations to become stuck during downward movement. Auxiliary tools are needed to knock them down, which is not only labor-intensive but also time-consuming. In addition, when the laminations are not clamped, there is air in the gaps. Direct clamping can easily cause air retention, affecting the overall quality of the stator and rotor. Summary of the Invention

Detailed Implementation

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0036] Reference Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a clamping device for processing motor parts. The clamping device for processing motor parts includes a clamping component 1, an external component 2, and a positioning component 3. By setting the external component 2 and the positioning component 3, uniform air jet treatment can be performed when the material moves down one by one to achieve the purpose of auxiliary lubrication and avoid blockage. Before the clamping operation, a negative pressure air extraction operation is performed to ensure the quality of the subsequent stator and rotor finished products. The discharged gas can also be used as an air jet source, without the need to set up additional pressurization equipment.

[0037] Specifically, the clamping assembly 1 includes a bearing seat 11, a hydraulic cylinder 12 is provided on the top of the bearing seat 11, a bracket 13 is fixed to the output end of the hydraulic cylinder 12, and a pressure equalizing ring 14 is fixed to the bottom of the bracket 13.

[0038] Specifically, the external component 2 is located on the top of the support base 11 and includes a positioning sleeve 21 fixed to the top of the support base 11. A sealing cylinder 22 is fixed to the outer ring of the positioning sleeve 21. An air extraction component 23 is provided on the top of the sealing cylinder 22. A driving component 24 is provided inside the sealing cylinder 22. A pushing component 25 is provided on the outer ring of the positioning sleeve 21. An air supply component 26 is provided on one side of the air extraction component 23. A hollow ring 27 is provided at the bottom of the inner cavity of the positioning sleeve 21.

[0039] By setting the air extraction component 23, displacement can be carried out simultaneously when the bracket 13 moves down to press, so as to achieve the purpose of negative pressure air extraction and ensure the quality of subsequent product processing.

[0040] By using the drive component 24 and the pusher component 25, the gas flow can be used during the evacuation process to assist in the pressure and positioning with the pusher component 25, which is beneficial to the quality of subsequent production and processing.

[0041] Specifically, the positioning component 3 is located on the top of the support base 11 and includes a positioning post 31 fixed at the center of the top of the support base 11. An upper sealing plate 32 is slidably connected to the top of the outer ring of the positioning post 31, and a lower sealing plate 34 is fixed to the bottom of the outer ring of the positioning post 31. A stator and rotor lamination 35 is placed between the upper sealing plate 32 and the lower sealing plate 34, and an auxiliary flow component 33 is provided on the outer ring of the positioning post 31.

[0042] By setting the auxiliary flow component 33, multiple auxiliary flow jets can be applied to the contact surface between the stator and rotor laminations 35 and the positioning post 31 during the downward movement of the stator and rotor laminations 35, which is beneficial for stacking multiple stator and rotor laminations 35 in sequence. Example 2

[0043] Reference Figures 2 to 11 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, a support rod 13-1 is fixed at the bottom of the bracket 13, and the bottom end of the support rod 13-1 protrudes from the bottom end of the equalizing ring 14.

[0045] The air extraction component 23 includes an auxiliary shell 23-1 fixed to the outer ring of the positioning sleeve 21. A first toothed plate 23-2 is slidably connected to the top of the auxiliary shell 23-1. A gear 23-3 is provided at the center of the auxiliary shell 23-1. A second toothed plate 23-5 is slidably connected to the bottom of the auxiliary shell 23-1. An auxiliary frame 23-6 is fixed to the bottom of the second toothed plate 23-5. A sealing head 23-7 is fixed to the bottom of the auxiliary frame 23-6.

[0046] The bottom of the first toothed plate 23-2 is fixed with a first spring 23-4. The bottom end of the first spring 23-4 is fixed inside the auxiliary shell 23-1. The auxiliary frame 23-6 is slidably connected to the sealing cylinder 22. The sealing head 23-7 is slidably connected inside the sealing cylinder 22.

[0047] The support rod 13-1 can move down together with the bracket 13 and the equalizing ring 14, and make contact with the first toothed plate 23-2 in advance, thereby pressing the first toothed plate 23-2 to move down gradually, completing the air extraction operation.

[0048] The first toothed plate 23-2 meshes with the gear 23-3, and the gear 23-3 meshes with the second toothed plate 23-5. Through the arrangement of the first toothed plate 23-2, the gear 23-3 and the second toothed plate 23-5, when the first toothed plate 23-2 moves downward, the second toothed plate 23-5 is driven by the gear 23-3 to gradually move upward.

[0049] The connection between the auxiliary frame 23-6 and the sealing cylinder 22, and the connection between the sealing head 23-7 and the sealing cylinder 22 are all sealed. With this design, when the support rod 13-1 moves down and presses against the first toothed plate 23-2 to move down simultaneously, the gear 23-3 will cooperate to make the second toothed plate 23-5 move up, thereby driving the auxiliary frame 23-6 and the sealing head 23-7 to move, which will increase the air storage space at the bottom of the sealing cylinder 22 and form a negative pressure to achieve the purpose of air extraction.

[0050] The driving component 24 includes a transmission pipe 24-1 fixed to the positioning sleeve 21. A cover 24-2 is provided over the transmission pipe 24-1. A pressing block 24-4 is fixed to one side of the cover 24-2. A displacement plate 24-5 is slidably connected to the bottom of the sealing cylinder 22. A support bar 24-3 is fixed to the other side of the cover 24-2. A second spring 24-31 is fixed on the support bar 24-3. The other end of the second spring 24-31 is fixed to the transmission pipe 24-1. A vent hole 24-21 is provided on the outer ring of the cover 24-2. A groove 24-41 is provided on the top of the pressing block 24-4. A through groove 24-51 is provided on the displacement plate 24-5 and is slidably connected to the groove 24-41.

[0051] A transfer valve 22-1 is fixed on one side of the sealing cylinder 22. There are two transfer valves 22-1. Both transfer valves 22-1 are equipped with a first check valve. The first check valve on the top transfer valve 22-1 has a flow direction from the outside to the sealing cylinder 22, while the first check valve on the bottom transfer valve 22-1 has a flow direction from the sealing cylinder 22 to the outside.

[0052] The ventilation holes 24-21 are designed as small holes and are distributed in a circular array on the cover 24-2.

[0053] A second check valve is installed on the transmission pipe 24-1, with the flow direction from the positioning sleeve 21 to the sealing cylinder 22.

[0054] By setting the drive component 24, when the bottom of the inner cavity of the sealing cylinder 22 is in a negative pressure state, the gas in the positioning sleeve 21 can be extracted and replenished to discharge the air in the positioning sleeve 21, which is beneficial to the pressing process of multiple stator and rotor laminations 35.

[0055] As the sealing head 23-7 gradually moves upward, the space inside the sealing cylinder 22 increases while the gas volume remains constant, creating a negative pressure environment. The gas inside the sealing cylinder 22 is transmitted to the sealing cylinder 22 via the transmission pipe 24-1. Due to the small diameter of the vent hole 24-21 and the large gas flow rate, the cover 24-2 automatically shifts, and the second spring 24-31 is compressed. With the cooperation of the inclined groove 24-41 and the through groove 24-51, it is used to push the displacement plate 24-5 upward.

[0056] The pusher 25 includes a displacement frame 25-1 that is slidably connected to the outer ring of the positioning sleeve 21. A connecting plate 25-2 is rotatably connected to the top of the displacement frame 25-1. A sealing strip 25-3 is rotatably connected to the top of the connecting plate 25-2. A sealing groove 25-4 is provided on the positioning sleeve 21 and is slidably connected to the sealing strip 25-3.

[0057] The top of the displacement frame 25-1 is fixed to the bottom of the displacement plate 24-5, and the sealing groove 25-4 and the sealing strip 25-3 are sealed.

[0058] The displacement frame 25-1 is equipped with a counterweight, meaning that the displacement frame 25-1 will automatically move downwards due to gravity when no external force is applied.

[0059] When the displacement frame 25-1 moves upward together with the displacement plate 24-5, under the connection of the connecting plate 25-2, multiple sealing strips 25-3 will slide simultaneously in the sealing groove 25-4 and be placed in the sealing cylinder 22 to push multiple stator and rotor laminations 35 to ensure that multiple stator and rotor laminations 35 are aligned; similarly, when the displacement frame 25-1 moves downward due to its own weight, the sealing strips 25-3 will retract into the sealing groove 25-4.

[0060] The gas supply component 26 includes a first gas supply pipe 26-1 fixed to one side of the sealing cylinder 22, and a second gas supply pipe 26-2 provided on the other side of the sealing cylinder 22. A return gas straight pipe 26-21 is fixed on the second gas supply pipe 26-2. One end of the first gas supply pipe 26-1 and the second gas supply pipe 26-2 are both fixed to the outer ring of the hollow ring 27. A gas supply hole 27-1 is opened in the inner ring of the hollow ring 27. A compression wheel 26-3 is provided on one side of the auxiliary shell 23-1. A positioning shaft 26-31 is fixed in the inner ring of the compression wheel 26-3 and is fixed to the inner ring of the gear 23-3. A protective shell 26-4 is fixed on one side of the auxiliary shell 23-1. A compression hose 26-5 is provided inside the protective shell 26-4. A filter head 26-51 is fixed at one end of the compression hose 26-5, and the other end of the compression hose 26-5 is connected to the second gas supply pipe 26-2.

[0061] The outer ring of the hollow ring 27 is equipped with a third one-way valve, with the flow direction from the first gas supply pipe 26-1 to the hollow ring 27, or from the second gas supply pipe 26-2 to the hollow ring 27; the return gas straight pipe 26-21 is equipped with a fourth one-way valve, with the flow direction from the outside to the second gas supply pipe 26-2.

[0062] The hollow ring 27 is embedded in the positioning post 31, and the air outlet 27-1 is connected to the air storage cavity 31-2.

[0063] When gear 23-3 rotates continuously, it drives extrusion wheel 26-3 to rotate, which is used to extrude extrusion hose 26-5, so that outside air is continuously replenished into hollow ring 27 through second air supply pipe 26-2. At the same time, as sealing head 23-7 moves upward, air above sealing cylinder 22 is input into hollow ring 27 through first air supply pipe 26-1, and finally placed into air storage chamber 31-2 for storage, so that the air volume in air storage chamber 31-2 increases and is in a positive pressure state.

[0064] A positioning rod 31-1 is fixed to the outer ring of the positioning post 31, and an air storage chamber 31-2 is opened inside the positioning post 31.

[0065] The auxiliary flow component 33 includes an arc-shaped groove 33-1 formed on the outer ring of the positioning post 31. A protrusion 33-2 is provided on the outer ring of the positioning post 31. An arc-shaped rod 33-4 is fixed in the arc-shaped groove 33-1 and is slidably connected to the protrusion 33-2. A third spring 33-5 is sleeved on the arc-shaped rod 33-4. A rotating plate 33-6 is rotatably connected in the positioning post 31.

[0066] One end of the third spring 33-5 is fixed inside the arc-shaped groove 33-1, and the other end of the third spring 33-5 is fixed on the protrusion 33-2. A rotating groove 33-7 is opened at the top of the inner cavity of the arc-shaped groove 33-1 and is slidably connected with the rotating plate 33-6. A protruding groove 33-8 is opened at the top of the inner cavity of the rotating groove 33-7. A flow equalization groove 33-3 is opened at the bottom of the inner cavity of the protruding groove 33-8. A support groove 33-9 is opened on one side of the inner cavity of the rotating groove 33-7.

[0067] The arc-shaped rod 33-4 can guide the displacement of the protrusion 33-2, ensuring the stability of the movement of the protrusion 33-2.

[0068] The inner ring of the stator and rotor lamination 35 has a winding slot 35-1. The inner diameter of the winding slot 35-1 is larger than the diameter of the protrusion 33-2, in order to avoid the presence of the protrusion 33-2 affecting the normal assembly of the stator and rotor lamination 35.

[0069] The rotating plate 33-6 and the rotating groove 33-7 are sealed. The protruding groove 33-8 is protruding from the rotating groove 33-7. That is, when the rotating plate 33-6 rotates below the protruding groove 33-8, the positive pressure gas in the gas storage chamber 31-2 will be transmitted through the support groove 33-9, the rotating groove 33-7 and the protruding groove 33-8, and finally sprayed through the flow equalization groove 33-3 to the space between the stator and rotor laminations 35 and the positioning column 31, which is conducive to the gradual falling and stacking of the stator and rotor laminations 35.

[0070] In use, the stator and rotor laminations 35 are lowered and fitted onto the positioning post 31. At the same time as the stator and rotor laminations 35 are inserted, the protrusions 33-2 are pressed down, causing the protrusions 33-2 to slide along the arc-shaped rod 33-4. The third spring 33-5 is compressed, and the protrusions 33-2 enter the arc-shaped groove 33-1 and squeeze the rotating plate 33-6 to rotate and open, so that the support groove 33-9 and the rotating groove 33-7 are connected. Finally, the positive pressure gas in the gas storage chamber 31-2 is ejected through the flow equalization groove 33-3, which helps the third spring 33-5 to quickly move down and stack.

[0071] After the multiple third springs 33-5 are stacked, the upper sealing plate 32 is fitted inside the positioning post 31 and sealed with the inner wall of the positioning sleeve 21.

[0072] The hydraulic cylinder 12 extends to work, causing the bracket 13, support rod 13-1 and pressure equalizing ring 14 to move down together. The support rod 13-1 first contacts the first toothed plate 23-2, pressing the first toothed plate 23-2 down. The first spring 23-4 is compressed, the gear 23-3 rotates, and the second toothed plate 23-5 gradually moves up, so as to drive the auxiliary frame 23-6 and the sealing head 23-7 to move, and the air storage space at the bottom of the sealing cylinder 22 increases.

[0073] Air at the bottom of the positioning sleeve 21 enters the sealing cylinder 22 through the transmission pipe 24-1 and the vent hole 24-21 to achieve negative pressure air extraction, which is used to eliminate air between multiple stator and rotor laminations 35 and ensure the quality of subsequent pressing and forming.

[0074] Because the vent 24-21 is small, as gas is introduced, the cover 24-2 will shift a certain distance, increasing the distance between the cover 24-2 and the transmission pipe 24-1 to meet the gas introduction requirements. The second spring 24-31 is compressed, and the pressing block 24-4 shifts along with the cover 24-2. With the cooperation of the inclined groove 24-41 and the through groove 24-51, the displacement plate 24-5 gradually moves upward.

[0075] As the displacement plate 24-5 moves upward, it drives the displacement frame 25-1 to move. With the cooperation of the connecting plate 25-2, the sealing strip 25-3 moves inward and contacts multiple stator and rotor laminations 35, achieving the purpose of alignment.

[0076] During the upward movement of the sealing head 23-7, the gas at the top of the sealing cylinder 22 is input into the hollow ring 27 through the first gas supply pipe 26-1. As the gear 23-3 rotates continuously, the extrusion wheel 26-3 rotates synchronously with the cooperation of the positioning shaft 26-31 to extrude the extrusion hose 26-5. This causes the outside air to be filtered by the filter head 26-51 and continuously input into the hollow ring 27. With the assistance of the gas supply hole 27-1, the gas is continuously filled into the gas storage chamber 31-2, so that the gas in the gas storage chamber 31-2 is kept in a positive pressure state, which meets the above-mentioned requirements for the blowing gas source.
