Description
Technical Field
[0001] This invention relates to the field of motor housing processing technology, and in particular to a punching device and punching method for a motor housing used in food processing. Background Technology
[0002] Punching dies are a pressure processing method that uses dies mounted on a press to apply pressure to materials, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. They are mainly used in industrial production. For example, punching dies are needed to punch holes in the outer shell and end caps of motor housings during production.
[0003] Existing technology discloses some invention patents for punching motor housings. Chinese utility model patent application number CN202020664082.0 discloses a punching mold for motor housings, including a base, a side support plate, a cylinder, an extrusion plate, a punching template, and clamping plates. A side support plate is welded to the center of one side of the base, and a hanging plate is welded to the inner top of the side support plate. A cylinder is fixed below the top of the hanging plate, and an extrusion plate is fixedly connected to the extended end of the cylinder. A punching template is fixed directly below the extrusion plate and on the base. Clamping plates are provided on both sides of the punching template.
[0004] When punching holes in the end cover of a motor, the end cover is first positioned and clamped, and then a punch is used to punch holes in the end cover. However, when punching mounting holes on the edge of the end cover, if the punching position is close to the edge of the end cover, the material may bulge outward during punching, resulting in uneven stress around the punched part of the end cover. At the same time, if the distance between the punching position and the edge of the end cover is too close, the end cover edge will have less bearing capacity, which may cause the end cover edge to break during punching. Summary of the Invention
[0005] The purpose of this invention is to solve the problems in the prior art where the distance between the punching position and the edge of the end cap is too close, which may cause the material to bulge outward during punching, resulting in uneven stress around the punched part of the end cap. At the same time, the distance between the punching position and the edge of the end cap is too close, which may lead to the end cap edge bearing less stress and thus breakage at the edge of the end cap during punching. Therefore, this invention proposes a punching device and punching method for a motor housing for food processing.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a punching device for a motor housing for food processing, comprising a base, side plates symmetrically fixed to the top of the base, support frames fixed to the top of each of the two side plates, a top plate fixed to the top of the two support frames, a first cylinder fixed to the bottom of the top plate, a mounting seat fixed to the telescopic end of the first cylinder, punches symmetrically fixed to the bottom of the mounting seat, material dropping holes symmetrically opened on the top of the base, an annular support block fixed to the top of the base, a cylinder fixed to the top of the annular support block, and a controller fixed to the front side of the support frame on the right side;
[0007] The top of the base is fixed with a pressing mechanism, which is used to fix the end cap and provide support for the side of the end cap.
[0008] The base is provided with a pressure detection mechanism on its top, which is used to detect the pressure between the pressing mechanism and the end cap side.
[0009] The top of the base is provided with a horizontal detection and adjustment mechanism, which is used to detect the horizontality of the upper surface of the end cap and adjust the surface of the end cap to be in a horizontal state.
[0010] During operation, if the punching position is close to the edge of the end cap, the material may bulge outwards during punching, resulting in uneven stress around the punched area on the end cap. Simultaneously, if the distance between the punching position and the edge of the end cap is too close, the end cap edge will have less load-bearing capacity, potentially leading to breakage at the edge during punching. This embodiment of the invention solves these problems. The specific implementation is as follows: First, the operator places the motor end cap to be punched on top of the base, then places the motor end cap on a matching annular support block, ensuring the cylinder on the annular support block extends from the shaft extension hole of the motor end cap, completing the initial installation of the end cap. Then, the pressing mechanism is activated to clamp both sides of the end cap. During clamping, the end cap can be rotated to ensure it is in the correct position before pressing and clamping both sides of the end cap. After the side is squeezed and clamped, a first request message is generated. Then, the first part of the pressing mechanism is activated to press the side of the end cap. Then, the controller activates the level detection and adjustment mechanism to detect the levelness of the upper surface of the end cap. If the upper surface of the end cap is not detected to be level, the level detection and adjustment mechanism is activated to adjust the upper surface of the end cap to be level. If the upper surface of the end cap is detected to be level, the first part of the pressing mechanism fixes and clamps the side of the end cap. Then, the second part of the pressing mechanism is controlled to clamp the side of the end cap. On the one hand, it can position the end cap, which is beneficial to improve the accuracy of the punching position. On the other hand, it can improve the support force on the edge of the end cap, which helps to prevent the edge of the end cap from breaking due to excessive outward force. Finally, the first cylinder is activated, and the first cylinder drives the punch to punch the end cap.
[0011] Preferably, the pressing mechanism includes two second cylinders, which are respectively fixed to opposite sides of the two side plates, and the output ends of the two second cylinders are each fixed with a mounting plate.
[0012] The two mounting plates are symmetrically provided with first mounting slots on opposite sides. The rear sides of the two mounting plates are fixed with motors by connecting brackets. The output shafts of the two motors pass through the side walls of the corresponding mounting plates and extend into the interior of the adjacent first mounting slots and are fixed with bidirectional threaded rods. The outer rings of the two bidirectional threaded rods are symmetrically threaded with pressure plates. The two pressure plates on the same bidirectional threaded rod are symmetrical about the middle of the bidirectional threaded rod.
[0013] Clamping assemblies are installed on the side walls of the two rear pressure plates. The two clamping assemblies are used together to fix and press the protruding part of the end cap.
[0014] During operation, the two second cylinders are activated, which drive the two side plates to move towards each other, squeezing and clamping the two sides of the end cap placed on top of the base. After the outer side of the end cap abuts against the side wall of the corresponding mounting plate, the controller controls the corresponding motor to start. The motor drives the corresponding bidirectional threaded rod to rotate, and the rotation of the bidirectional threaded rod drives the two pressure plates threaded to it to move towards each other. The four pressure plates squeeze the outer side of the end cap, cooperating with the two mounting plates to squeeze the edge of the end cap and provide support. The two pressure plates on the rear side drive the clamping assembly to fix and press the protruding part of the end cap, which helps to support the edge of the end cap during the punching process and helps to prevent the edge of the end cap from breaking during the punching process.
[0015] Preferably, the clamping assembly includes a first electric push rod, which is fixed to the rear side of the pressure plate. A fixing plate is slidably sleeved on the telescopic end of the first electric push rod. A slot is formed through the rear side of the fixing plate. The telescopic end of the first electric push rod extends through the outer wall of the fixing plate and enters the interior of the slot, where a sliding plate is fixed. The sliding plate is slidably connected to the slot. A sliding groove is formed on the side of the fixing plate away from the first electric push rod. A sliding block is slidably connected to the side wall of the fixing plate through the sliding groove. The sliding block matches the protruding side of the end cap. Two first elastic telescopic rods are fixed on the inner wall of the sliding groove. The telescopic ends of the two first elastic telescopic rods are fixedly connected to the side wall of the sliding block.
[0016] A locking assembly is installed inside the fixed plate. After the first electric push rod is activated, the locking assembly is used to position the fixed plate and the sliding block.
[0017] During operation, the movement of the pressure plate drives the first electric push rod to move synchronously. The first electric push rod drives the fixed plate and the sliding plate to move synchronously. The fixed plate drives the sliding block to move through the elastic force of the first elastic telescopic rod. After one side of the sliding block abuts against the edge of the end cap protrusion, as the fixed plate continues to move, the distance between the first elastic telescopic rod and the sliding block shortens, compressing the first elastic telescopic rod. The elastic force of the first elastic telescopic rod makes one side of the sliding block fit tightly against the outer side of the end cap protrusion. Then, the controller controls the first electric push rod to start. The first electric push rod pushes the sliding plate to move until it abuts against the side wall of the slot, and then continues to push the fixed plate to move. The fixed plate drives the sliding block to press against the side of the end cap protrusion, completing the clamping of the side of the end cap. After the sliding plate moves until it abuts against the side wall of the slot, the locking component is activated to fix the sliding block to the fixed plate, providing support for the outer side of the end cap protrusion. This helps to provide support force for the outer side of the end cap and helps to prevent the edge of the end cap from breaking during the punching process.
[0018] Preferably, the locking assembly includes a groove, a connecting groove, a first rack, and a trapezoidal block. The groove is formed on the side of the sliding block facing the corresponding sliding groove. A gear is rotatably connected to the inner wall of the groove. The connecting groove is formed on the inner wall of the sliding groove, and the groove and the sliding groove are connected through the connecting groove. The first rack is fixed to the inner wall of the sliding groove and meshes with the gear. A second elastic telescopic rod is symmetrically fixed to the top of the first rack. The telescopic ends of the two second elastic telescopic rods are jointly fixed to the second rack. The trapezoidal block is fixed to the side of the sliding plate facing the gear and is slidably connected to the connecting groove.
[0019] Preferably, the pressure detection mechanism includes two first pressure sensors, two second pressure sensors, and two third pressure sensors. The two first pressure sensors are respectively fixed on the arc-shaped surfaces of the two mounting plates, the two second pressure sensors are respectively fixed on the front sides of the two pressure plates located at the rear, and the two third pressure sensors are respectively fixed on the inner sides of the two sliding blocks.
[0020] Preferably, the level detection and adjustment mechanism includes an electronic level and four second mounting slots. The electronic level is fixed to the top of the mounting plate on the left side. The four second mounting slots are respectively opened at the bottom of the four pressure plates. A second electric push rod is fixed inside each of the four second mounting slots. A slider is fixed to the telescopic end of each of the four second electric push rods. The four sliders are slidably connected to the corresponding second mounting slots. Each of the four sliders has an inclined surface.
[0021] Preferably, the outer rings of both punches are fitted with springs, the tops of both springs are fixedly connected to the mounting base, the bottoms of all springs are fixed with rings, and all rings are slidably connected to the corresponding punches.
[0022] A negative pressure pump is fixed to the rear side of the mounting base via a connecting plate. Both of the two rings have cavities inside, and multiple air outlets are provided on the inner side of both rings. The negative pressure pump is fixedly connected to the two cavities via two pipes.
[0023] A camera is fixedly mounted on the bottom of the mounting base.
[0024] A punching method for a punching device for a motor housing in food processing, the punching method comprising the following steps:
[0025] Obtain first request information, which is generated by the pressure testing agency after obtaining first pressure information;
[0026] Generate the first control information;
[0027] The first control information is sent to the edge pressing mechanism to control the first part of the edge pressing mechanism to start the initial clamping;
[0028] Obtain second request information, which is generated by the pressure testing agency after obtaining second pressure information;
[0029] Generate second control information;
[0030] The second control information is sent to the level detection and adjustment mechanism to control the level detection and adjustment mechanism to perform level detection;
[0031] Obtain a third request information or obtain a fourth request information, wherein the third request information is generated by the horizontal detection and adjustment mechanism after obtaining tilt information, and the fourth request information is generated by the horizontal detection and adjustment mechanism after obtaining horizontal information;
[0032] If a third request is obtained, then third control information is generated.

[0036] The fifth control information is sent to the level detection and adjustment mechanism to control the level detection and adjustment mechanism to perform a secondary level detection;
[0037] If the fourth request information is obtained, then the fourth control information is generated;
[0038] The fourth control information is sent to the edge pressing mechanism to control the first part of the edge pressing mechanism to perform fixed clamping;
[0039] Obtain the sixth request information, which is generated by the pressure detection agency after obtaining the third pressure;

[0043] Generate the seventh control information;
[0044] The seventh control information is sent to the first cylinder to control the first cylinder to start;
[0045] The pressing mechanism comprises two parts: the left and right sides, and the rear side. A pressure detection mechanism generates first pressure information upon detecting contact between the pressing mechanism and the left and right sidewalls of the end cap, requesting the controller to control the first part of the pressing mechanism to initially clamp the front and rear sides of the end cap. A second pressure information is generated upon detecting contact between the first part of the pressing mechanism and the sidewalls of the end cap, requesting the controller to control the leveling adjustment mechanism for leveling. A third request is generated upon detecting a tilt on the end cap surface, requesting the controller to control the leveling adjustment mechanism to adjust the upper surface of the end cap to a horizontal position. After the end cap surface is leveled, a fifth request message is generated, requesting the controller to control the level detection and adjustment mechanism to perform a second level detection. After the level detection and adjustment mechanism detects that the end cap surface is level, a fourth request message is generated, requesting the controller to control the first part of the pressing mechanism to fix and clamp the side wall of the end cap. After the pressure detection mechanism detects that the first part of the pressing mechanism has fixed and clamped the side wall of the end cap, a sixth request message is generated, requesting the controller to control the second part of the pressing mechanism to clamp the outer side of the end cap protrusion. After the pressure detection mechanism detects that the second part of the pressing mechanism has fixed and clamped the side wall of the end cap protrusion, a seventh request message is generated, requesting the controller to control the first cylinder to start.
[0046] Preferably, the specific pressing method of the pressing mechanism includes the following steps:
[0047] Upon obtaining the first control information, the edge clamping mechanism initiates the first part of the initial clamping;
[0048] Upon receiving the fourth control information, the edge pressing mechanism initiates the first part of the initial fixing and clamping.
[0049] Upon receiving the sixth control information, the edge pressing mechanism initiates the second part for clamping.
[0050] Specifically, after obtaining the first control information, the pressure plate moves close to the outer wall of the end cover to initially clamp the outer wall of the end cover; after obtaining the fourth control information, the pressure plate moves close to the outer wall of the end cover to fix and clamp the outer wall of the end cover; and after obtaining the sixth control information, the sliding block clamps and supports the outer side of the end cover protrusion.
[0051] Preferably, the specific testing method of the pressure testing mechanism is as follows:
[0052] Obtain initial pressure information;
[0053] Generate the first request information;
[0054] Send the first request information to the controller;
[0055] Obtain second pressure information;
[0056] Generate a second request message;
[0057] Send the second request information to the controller;
[0058] Obtain third-party pressure information;
[0059] Generate third request information;
[0060] Send the third request information to the controller;
[0061] Obtain fourth pressure information;
[0062] Generate the fourth request information;
[0063] Send the fourth request information to the controller;
[0064] Specifically, when the arc-shaped surface on the mounting plate contacts the left and right sides of the end cap, the first pressure information is obtained and the first request information is generated. After the pressure plate initially contacts the outer side of the end cap, the second pressure information is obtained and the second request information is generated. After the pressure plate makes close contact with the outer side of the end cap, the sixth request information is generated. After the sliding block makes close contact with the outer side of the end cap protrusion, the seventh request information is generated.
[0065] Compared with the prior art, the present invention has the following beneficial effects:
[0066] 1. By using the edge clamping mechanism to fix and hold the edge of the end cap, the end cap can be positioned, which helps to improve the accuracy of the punching position. On the other hand, it can increase the support force on the edge of the end cap, thereby helping to prevent the edge of the end cap from breaking due to excessive outward force.
[0067] 2. The motor drives the corresponding bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the two pressure plates connected to it to move in opposite directions. The four pressure plates press against the outside of the end cap, and cooperate with the two mounting plates to press the edge of the end cap and provide support. The two pressure plates on the rear side drive the clamping assembly to fix and press the protruding part of the end cap, which helps to provide support for the edge of the end cap during the punching process and helps to prevent the edge of the end cap from breaking during the punching process.
[0068] 3. The first electric push rod pushes the slide plate until it abuts against the side wall of the slot, and then continues to push the fixed plate to move. The fixed plate drives the sliding block to press against the side of the end cap protrusion, thus clamping the side of the end cap. After the slide plate moves until it abuts against the side wall of the slot, the locking assembly is activated to fix the sliding block to the fixed plate, providing support for the outer side of the end cap protrusion. This helps to provide support force for the outer side of the end cap and helps to prevent the edge of the end cap from breaking during the punching process. Attached Figure Description

[0084] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0085] like Figures 2 to 12 The device shown is a punching device for a motor housing for food processing. It includes a base 1, side plates 2 are symmetrically fixed on the top of the base 1, support frames 3 are fixed on the top of the two side plates 2, and a top plate 4 is fixed on the top of the two support frames 3. A first cylinder 5 is fixed on the bottom of the top plate 4, a mounting seat 6 is fixed on the telescopic end of the first cylinder 5, and a punch 7 is symmetrically fixed on the bottom of the mounting seat 6. A material dropping hole 8 is symmetrically opened on the top of the base 1, an annular support block 9 is fixed on the top of the base 1, a cylinder 10 is fixed on the top of the annular support block 9, and a controller 11 is fixed on the front side of the support frame 3 on the right side.
[0086] A pressing mechanism is fixed to the top of the base 1. The pressing mechanism is used to fix the end cap and provide support for the side of the end cap.
[0087] A pressure detection mechanism is provided on the top of the base 1. The pressure detection mechanism is used to detect the pressure between the pressing mechanism and the edge of the end cap.
[0088] A horizontal detection and adjustment mechanism is provided on the top of the base 1. This mechanism is used to detect the horizontality of the upper surface of the end cap and adjust it to a horizontal state. During operation, if the punching position is close to the edge of the end cap, the material may bulge outwards during punching, resulting in uneven stress around the punched area on the end cap. Additionally, if the distance between the punching position and the edge of the end cap is too close, the edge of the end cap will have less load-bearing capacity, potentially leading to breakage at the edge during punching. This embodiment of the invention solves these problems. The specific implementation is as follows: First, the operator places the motor 15 end cap to be punched on the top of the base 1, and then places the motor 15 end cap on a matching annular support block 9, ensuring that the cylinder 10 on the annular support block 9 extends from the shaft extension hole of the motor 15 end cap, completing the initial installation of the end cap. Then, the pressing mechanism is activated to clamp both sides of the end cap, allowing the end cap to rotate during clamping. After the end cap is positioned correctly, both sides of the end cap are squeezed and clamped. After squeezing and clamping both sides of the end cap, a first request message is generated. Then, the first part of the pressing mechanism is activated to press the side of the end cap. Then, the controller 11 activates the level detection and adjustment mechanism to detect the levelness of the upper surface of the end cap. If the upper surface of the end cap is not detected to be level, the level detection and adjustment mechanism is activated to adjust the upper surface of the end cap to be level. If the upper surface of the end cap is detected to be level, the first part of the pressing mechanism fixes and clamps the side of the end cap. Then, the second part of the pressing mechanism is controlled to clamp the side of the end cap. On the one hand, the end cap can be positioned, which helps to improve the accuracy of the punching position. On the other hand, it can increase the support force on the edge of the end cap, which helps to prevent the edge of the end cap from breaking due to excessive outward force. Finally, the first cylinder 5 is activated, and the first cylinder 5 drives the punch 7 to punch the end cap.
[0089] As one embodiment of the present invention, the pressing mechanism includes two second cylinders 12, which are respectively fixed to the opposite sides of the two side plates 2, and the output ends of the two second cylinders 12 are each fixed with a mounting plate 13.
[0090] Two mounting plates 13 are symmetrically provided with first mounting slots 14 on opposite sides. Motors 15 are fixed to the rear side of both mounting plates 13 by connecting brackets. The output shafts of the two motors 15 pass through the side wall of the corresponding mounting plate 13 and extend into the interior of the adjacent first mounting slots 14 and are fixed with bidirectional threaded rods 16. The outer rings of the two bidirectional threaded rods 16 are symmetrically threaded with pressure plates 17. The two pressure plates 17 on the same bidirectional threaded rod 16 are symmetrical about the middle of the bidirectional threaded rod 16.
[0091] Clamping assemblies are installed on the side walls of the two rear pressure plates 17. The two clamping assemblies are used together to fix and press the protruding part of the end cap. During operation, the two second cylinders 12 are started. The two second cylinders 12 drive the two side plates 2 to move towards each other, squeezing and clamping the two sides of the end cap placed on the top of the base 1. After the outer side of the end cap abuts against the side wall of the corresponding mounting plate 13, the controller 11 controls the corresponding motor 15 to start. The motor 15 drives the corresponding bidirectional threaded rod 16 to rotate. The rotation of the bidirectional threaded rod 16 drives the two pressure plates 17 threaded to it to move towards each other. The four pressure plates 17 press against the outer side of the end cap, and cooperate with the two mounting plates 13 to squeeze the edge of the end cap and provide support. The two rear pressure plates 17 drive the clamping assemblies to fix and press the protruding part of the end cap, which helps to provide support for the edge of the end cap during the punching process and helps to prevent the edge of the end cap from breaking during the punching process.
[0092] In one embodiment of the present invention, the clamping assembly includes a first electric push rod 18, which is fixed to the rear side of the pressure plate 17. The telescopic end of the first electric push rod 18 is slidably fitted with a fixing plate 19. A slot 20 is opened through the rear side of the fixing plate 19. The telescopic end of the first electric push rod 18 extends through the outer wall of the fixing plate 19 and enters the interior of the slot 20 and is fixed with a sliding plate 22. The sliding plate 22 is slidably connected to the slot 20. A sliding groove 21 is opened on the side of the fixing plate 19 away from the first electric push rod 18. A sliding block 23 is slidably connected to the side wall of the fixing plate 19 through the sliding groove 21. The sliding block 23 matches the side of the end cap protrusion. Two first elastic telescopic rods 24 are fixed on the inner wall of the sliding groove 21. The telescopic ends of the two first elastic telescopic rods 24 are fixedly connected to the side wall of the sliding block 23.
[0093] A locking assembly is installed inside the fixed plate 19. After the first electric push rod 18 is activated, the locking assembly is used to position the fixed plate 19 and the sliding block 23. During operation, the first electric push rod 18 moves synchronously as the pressure plate 17 moves. The first electric push rod 18 moves the fixed plate 19 and the sliding plate 22 synchronously. The fixed plate 19 moves the sliding block 23 through the elastic force of the first elastic telescopic rod 24. After the sliding block 23 abuts against the edge of the end cap protrusion on one side, as the fixed plate 19 continues to move, the distance between the first elastic telescopic rod 24 and the sliding block 23 shortens, compressing the first elastic telescopic rod 24. The force causes one side of the sliding block 23 to fit tightly against the outer side of the end cap protrusion. Then, the controller 11 controls the first electric push rod 18 to start. The first electric push rod 18 pushes the slide plate 22 to move until it touches the side wall of the slot 20, and then continues to push the fixing plate 19 to move. The fixing plate 19 causes the sliding block 23 to press against the side of the end cap protrusion, completing the clamping of the side of the end cap. After the slide plate 22 moves until it touches the side wall of the slot 20, the locking assembly is activated to fix the sliding block 23 and the fixing plate 19, providing support for the outer side of the end cap protrusion. This helps to provide support force for the outer side of the end cap and helps to prevent the edge of the end cap from breaking during the punching process.
[0094] In one embodiment of the present invention, the locking assembly includes a groove 25, a connecting groove 26, a first rack 27, and a trapezoidal block 28. The groove 25 is formed on the side of the sliding block 23 facing the corresponding sliding groove 21. A gear 29 is rotatably connected to the inner wall of the groove 25. The connecting groove 26 is formed on the inner wall of the sliding groove 21, and the slot 20 and the sliding groove 21 are connected through the connecting groove 26. The first rack 27 is fixed to the inner wall of the sliding groove 21 and meshes with the gear 29. A second elastic telescopic rod 30 is symmetrically fixed to the top of the first rack 27. The telescopic ends of the two second elastic telescopic rods 30 are jointly fixed to the second rack 31. The trapezoidal block 28 is fixed to the sliding plate 22 facing the gear. On one side of wheel 29, trapezoidal block 28 is slidably connected to connecting groove 26. During operation, sliding plate 22 moves, causing trapezoidal block 28 to pass through connecting groove 26 and enter the interior of groove 25. The inclined surface of trapezoidal block 28 presses against the top of second rack 31, pushing second rack 31 to move downward. Second rack 31 moves downward and meshes with gear 29. Gear 29 is fixed under the symmetrical clamping of first rack 27 and second rack 31, thereby fixing the position of sliding block 23. The elastic force of first elastic telescopic rod 24 is transformed into the rigid force that fixes sliding block 23, providing more stable support for the outer side of end cap protrusion, which is conducive to the stable clamping of the outer side of end cap protrusion.
[0095] In one embodiment of the present invention, the pressure detection mechanism includes two first pressure sensors 32, two second pressure sensors 33, and two third pressure sensors 34. The two first pressure sensors 32 are respectively fixed to the arcuate surfaces of two mounting plates 13, the two second pressure sensors 33 are respectively fixed to the front sides of two pressure plates 17 located at the rear, and the two third pressure sensors 34 are respectively fixed to the inner sides of two sliding blocks 23. During operation, after the arcuate surface on the mounting plate 13 contacts the outer wall of the end cap, the first pressure sensor 32 acquires first pressure information, then controls the start motor 15 to drive the pressure plates 17 to initially clamp the side walls of the end cap, and then the second... Pressure sensor 33 acquires second pressure information, and then controller 11 controls the level detection and adjustment mechanism to adjust the levelness of the upper surface of the end cap. Next, controller 11 controls motor 15 to start. Motor 15 drives pressure plate 17 to clamp the outer wall of the end cap. Then, second pressure sensor 33 acquires third pressure information. Then, controller 11 controls first electric push rod 18 to start. First electric push rod 18 presses one side of sliding block 23 against the protruding side wall of end cap, so that third pressure sensor 34 acquires fourth pressure information. Then, controller 11 controls first cylinder 5 to start. First cylinder 5 drives punch 7 to descend and punch the end cap.
[0096] In one embodiment of the present invention, the level detection and adjustment mechanism includes an electronic level 35 and four second mounting slots 36. The electronic level 35 is fixed to the top of the mounting plate 13 on the left side. The four second mounting slots 36 are respectively opened at the bottom of the four pressure plates 17. A second electric push rod 37 is fixed inside each of the four second mounting slots 36. A slider 38 is fixed to the telescopic end of each of the four second electric push rods 37. The four sliders 38 are slidably connected to the corresponding second mounting slots 36. Each of the four sliders 38 has an inclined surface. During operation, the uneven surface of the end cap will cause the mounting hole punched during the punching process to be skewed, and the end cap will be unstable under force during the punching process. Cracks are more likely to occur when punching holes at the edges. The electronic level 35 can be used to detect the levelness of the upper surface of the end cap. If the end cap surface is flat, the motor 15 is started to clamp the outer side of the end cap. If the end cap surface is not flat, the controller 11 controls the second electric push rod 37 at the corresponding low position to start. The second electric push rod 37 pushes the slider 38 to move. The inclined surface of the slider 38 pushes the bottom of the end cap, so that the side of the end cap slides on the inclined surface, thereby raising the local height of the end cap and adjusting the upper surface of the end cap to be level. Then, the motor 15 is started to drive the pressure plate 17 to clamp the outer side of the end cap.
[0097] In one embodiment of the present invention, springs 39 are fitted around the outer rings of the two punches 7, the tops of the two springs 39 are fixedly connected to the mounting base 6, and rings 40 are fixedly attached to the bottoms of all the springs 39. All the rings 40 are slidably connected to the corresponding punches 7.
[0098] The negative pressure pump 41 is fixed to the rear side of the mounting base 6 by a connecting plate. The interior of the two rings 40 is provided with cavities 42, and the inner side of the two rings 40 is provided with multiple air outlets 43. The negative pressure pump 41 is fixedly connected to the two cavities 42 through two pipes 44 respectively.
[0099] A camera 45 is fixedly installed at the bottom of the mounting base 6. During operation, the ring 40 compresses the spring 39 as the punch 7 moves downward to punch, and the elastic force of the spring 39 provides pressure to the edge of the punching position on the top of the end cap, thereby increasing the stability of the end cap edge during the punching process. At the same time, after the first cylinder 5 is started, the negative pressure pump 41 starts to draw air, and the outside air enters the cavity 42 through the air outlet 43 through the two pipes 44 and then enters the interior of the pipes 44. The airflow generated by the rapid air flow can blow the end of the punch 7, thereby cleaning the end of the punch 7 and removing the debris that is attached to the end of the punch 7 due to the reciprocating punching. This helps to prevent the end cap from cracking due to unstable force during punching caused by uneven end. After punching is completed, the camera 45 can take pictures and collect data on the surface of the punched end cap after the first cylinder 5 drives the punch 7 to rise, thereby detecting whether there are cracks on the surface of the end cap.
[0100] like Figure 1 The method for punching holes in a punching device for a motor housing used in food processing includes the following steps:
[0101] Obtain first request information, which is generated by the pressure testing agency after obtaining first pressure information;
[0102] Generate the first control information;
[0103] The first control information is sent to the edge pressing mechanism to control the first part of the edge pressing mechanism to perform initial clamping;
[0104] Obtain second request information, which is generated by the pressure testing agency after obtaining second pressure information;
[0105] Generate second control information;
[0106] The second control information is sent to the level detection and adjustment mechanism to control the level detection and adjustment mechanism to perform level detection and adjustment;
[0107] Obtain third request information or fourth request information, both of which are generated by the level detection and adjustment mechanism after obtaining the levelness information;
[0108] If a third request is obtained, then third control information is generated.
[0109] The third control information is sent to the level detection and adjustment mechanism to control the level detection and adjustment mechanism to perform level adjustment;
[0110] Obtain the fifth request information, which is generated by the horizontal detection and adjustment mechanism after obtaining the horizontal adjustment completion information;
[0111] Generate the fifth control information;
[0112] The fifth control information is sent to the edge pressing mechanism to control the first part of the edge pressing mechanism to perform fixed clamping;
[0113] If the fourth request information is obtained, then the fourth control information is generated;
[0114] The fourth control information is sent to the edge pressing mechanism to control the first part of the edge pressing mechanism to perform fixed clamping;
[0115] Obtain the sixth request information, which is generated by the pressure detection agency after obtaining the third pressure;
[0116] Generate the sixth control information;
[0117] The sixth control information is sent to the edge pressing mechanism to control the second part of the edge pressing mechanism to clamp;
[0118] Obtain the seventh request information, which is generated by the pressure detection agency after obtaining the fourth pressure;
[0119] Generate the seventh control information;
[0120] The seventh control information is sent to the first cylinder 5 to control the first cylinder 5 to start;
[0121] The pressing mechanism consists of two parts: the left and right sides, and the rear side. The pressure detection mechanism generates first pressure information upon detecting contact between the pressing mechanism and the left and right sidewalls of the end cap, requesting the controller to control the first part of the pressing mechanism to initially clamp the front and rear sides of the end cap. The pressure detection mechanism then generates second pressure information upon detecting contact between the first part of the pressing mechanism and the sidewalls of the end cap, requesting the controller to control the leveling adjustment mechanism for leveling. Upon detecting a tilt on the end cap surface, the leveling adjustment mechanism generates a third request, requesting the controller to control the leveling adjustment mechanism to adjust the upper surface of the end cap to a horizontal position. After leveling the end cap surface, the leveling adjustment mechanism generates a fifth request, requesting the controller to control the leveling adjustment mechanism for a second leveling detection.
[0122] After the level detection and adjustment mechanism detects that the end cap surface is level, it generates a fourth request message, requesting the controller to control the first part of the pressing mechanism to fix and clamp the side wall of the end cap. After the pressure detection mechanism detects that the first part of the pressing mechanism has fixed and clamped the side wall of the end cap, it generates a sixth request message, requesting the controller to control the second part of the pressing mechanism to clamp the outer side of the end cap protrusion. After the pressure detection mechanism detects that the second part of the pressing mechanism has fixed and clamped the side wall of the end cap protrusion, it generates a seventh request message, requesting the controller to control the first cylinder 5 to start.
[0123] like Figure 13 As shown, in one embodiment of the present invention, the specific pressing method of the pressing mechanism includes the following steps:
[0124] Upon obtaining the first control information, the edge clamping mechanism initiates the first part of the initial clamping;
[0125] Upon receiving the fourth or fifth control information, the edge pressing mechanism initiates the first part of preliminary fixing and clamping.
[0126] Upon receiving the sixth control information, the edge pressing mechanism initiates the second part of the edge pressing process;
[0127] After obtaining the first control information, the pressure plate 17 moves close to the outer wall of the end cover to perform initial clamping on the outer wall of the end cover. After obtaining the fourth control information, the pressure plate 17 moves close to the outer wall of the end cover to perform fixed clamping on the outer wall of the end cover. After obtaining the sixth control information, the sliding block 23 clamps and supports the outer side of the end cover protrusion.
[0128] like Figure 14 As shown, in one embodiment of the present invention, the specific detection method of the edge pressing detection mechanism is as follows:
[0129] Obtain initial pressure information;
[0130] Generate the first request information;
[0131] Send the first request information to controller 11;
[0132] Obtain second pressure information;
[0133] Generate a second request message;
[0134] Send the second request information to controller 11;
[0135] Obtain third-party pressure information;
[0136] Generate third request information;
[0137] Send the third request information to controller 11;
[0138] Obtain fourth pressure information;
[0139] Generate the fourth request information;
[0140] Send the fourth request information to controller 11;
[0141] When the arc-shaped surface on the mounting plate 13 contacts the left and right sides of the end cap, the first pressure information is obtained and the first request information is generated. After the pressure plate 17 initially contacts the outer side of the end cap, the second pressure information is obtained and the second request information is generated. After the pressure plate 17 makes close contact with the outer side of the end cap, the sixth request information is generated. After the sliding block 23 makes close contact with the outer side of the end cap protrusion, the seventh request information is generated.
[0142] Working principle of this invention:
[0143] During operation, if the punching position is close to the edge of the end cap, the material may bulge outwards during punching, resulting in uneven stress around the punched area on the end cap. Simultaneously, if the distance between the punching position and the edge of the end cap is too close, the end cap edge will have less load-bearing capacity, potentially leading to breakage at the edge during punching. This embodiment of the invention solves these problems. The specific implementation is as follows: First, the operator places the motor 15 end cap to be punched on the top of the base 1, and then places the motor 15 end cap on a matching annular support block 9, ensuring that the cylinder 10 on the annular support block 9 extends from the shaft extension hole of the motor 15 end cap, completing the initial installation of the end cap. Then, the pressing mechanism is activated to clamp both sides of the end cap. During clamping, the end cap can be rotated to ensure it is in the correct position before pressing and clamping both sides of the end cap to complete the final installation. After the two sides of the cap are squeezed and clamped, a first request message is generated. Then, the first part of the pressing mechanism is activated to press the side of the end cap. Then, the controller 11 activates the level detection and adjustment mechanism to detect the levelness of the upper surface of the end cap. If the upper surface of the end cap is not detected to be level, the level detection and adjustment mechanism is activated to adjust the upper surface of the end cap to be level. If the upper surface of the end cap is detected to be level, the first part of the pressing mechanism fixes and clamps the side of the end cap. Then, the second part of the pressing mechanism is controlled to clamp the side of the end cap. On the one hand, the end cap can be positioned, which helps to improve the accuracy of the punching position. On the other hand, it can improve the support force on the edge of the end cap, which helps to prevent the edge of the end cap from breaking due to excessive outward force. Finally, the first cylinder 5 is activated, and the first cylinder 5 drives the punch 7 to punch the end cap.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
