Description

Technical Field

[0001] This invention belongs to the field of stamping equipment, and in particular relates to a stamping equipment for automatically tilting the stamping surface of the motor base plate mounting hole. Background Technology

[0002] A motor mount is a basic component used to mount and fix a motor. Its functions include stabilizing and fixing the motor, protecting the motor, transmitting power, and adjusting the mounting position and angle. It is mostly made of cast iron, steel plate, or aluminum alloy, and its structure includes integral, adjustable, and modular types. The surface is often treated with phosphate blackening or painting to enhance performance. An integral motor mount has a central motor shaft hole surrounded by a ring of support surfaces with motor mounting holes, the positions of which correspond to the mounting holes on the motor itself.

[0003] The motor is manufactured and assembled by the motor manufacturer with a motor mounting plate. However, after the motor mounting plate is fixed to the motor, there is always a discrepancy between the mounting holes on the mounting plate and the motor shaft. This causes the motor shaft to tilt when the motor is installed onto the motor mount. To ensure the accuracy of the motor shaft shaft, adjustments must be made for each installation to meet the required accuracy. However, since the installation position of each motor is different, the adjustments are different for each installation, making installation and correction time-consuming and severely impacting installation efficiency.

[0004] However, product assembly manufacturers cannot control the production of motor manufacturers. Therefore, an automatic tilting angle stamping device for the motor mount hole punching surface is proposed. The device produces motor mounts specifically according to the motor installation parameters from the motor manufacturer, thereby ensuring the axial accuracy of the motor shaft during motor installation. Summary of the Invention

[0005] This invention provides an automatic tilting angle stamping device for the motor mount hole stamping surface. The worktable is designed as a tiltable structure. After the motor mount is placed and fixed on the worktable, it can tilt with the worktable. When the upper punch presses to the tilted part, it stamps an inclined micro-protrusion around the motor mount hole, thereby ensuring that the periphery of the mounting hole in this part is consistent with the corresponding position of the motor mounting plate to be installed. After multiple micro-protrusions cooperate with each other, it can ensure that the motor axis meets the installation requirements after the motor is installed, reduce the time required for motor installation and adjustment, reduce installation and correction work, and improve installation efficiency.

[0006] The specific technical solution of the present invention is as follows: an automatic tilting angle stamping device for the stamping surface of a motor base plate mounting hole, comprising a frame, a stamping upper die head disposed on the upper part of the frame, a worktable disposed on the lower part of the frame, and a tilting device disposed below the worktable to support the worktable and enable the worktable to tilt at any angle; a positioning column and a motor base plate fixing device are disposed on the worktable, and an elastic support component is disposed on the surface of the worktable corresponding to the position of the motor base plate mounting hole, and a shaft hole positioning component adapted to the shaft hole of the motor base plate is disposed at the center of the worktable; the tilting of the worktable is based on the center of the shaft hole of the motor base plate; the stamping position of the stamping upper die head corresponds to the position of the motor base plate mounting hole, and the stamping upper die head is a telescopic structure.

[0007] The worktable holds the motor base plate. A fixing device secures the motor base plate, and positioning pins position it so that the stamping position of the upper stamping die aligns with the mounting hole position on the motor base plate, ensuring the correct positioning of the micro-protrusion. A tilting device supports the worktable and tilts it according to the parameters of the motor mounting plate. After tilting, the motor base plate on the worktable tilts accordingly, ensuring the micro-protrusion processed by the upper stamping die meets the requirements. The parameters of the micro-protrusions around the mounting holes on the motor base plate are determined based on the installation parameters of the motor mounting plate. Once the installation parameters of the motor mounting plate are determined, the parameters of the micro-protrusions can be obtained through design calculations. A shaft hole positioning component on the worktable positions the shaft holes. When the worktable tilts, it tilts with the center of the shaft hole on the motor base plate as a reference. This ensures that the height and angle of the micro-protrusions processed by the upper stamping die after the worktable is tilted, guaranteeing that the motor axis meets the requirements after the motor mounting plate is installed and fixed. This design reduces the time required for motor installation and adjustment, alleviates installation and correction work, and improves installation efficiency. Simultaneously, a position sensor is installed on the shaft hole positioning component to provide feedback on the tilt angle of the worktable, ensuring that the micro-protrusions formed after the worktable is tilted meet the requirements. The elastic support component supports the area around the motor base plate mounting holes and also clamps the area around the mounting holes during stamping by the upper stamping die, ensuring the micro-protrusions are formed correctly. The upper stamping die uses a telescopic structure, allowing the number of upper stamping dies involved in each stamping operation to be selected according to actual needs. Depending on the parameters of the micro-protrusions, if the parameters of each micro-protrusion are different, one upper stamping die is used for individual forming; if the parameters of two or more micro-protrusions are the same, multiple upper stamping dies form them simultaneously. When the worktable does not need to be tilted, the tilting device only serves a supporting function, and all upper stamping dies work simultaneously, forming micro-protrusions around the mounting holes of the motor base plate at the same time.

[0008] Preferably, the upper stamping die includes a stamping lifting main rod and a fixed plate disposed at the end of the lifting main rod. A telescopic stamping head is mounted on the fixed plate, and the position of the telescopic stamping head corresponds to the position of the mounting hole on the motor base plate. The extension and retraction of the upper stamping die is achieved through the extension and retraction of the telescopic stamping head. The lifting main rod drives the fixed plate to rise and fall, and the fixed plate drives the telescopic stamping head downward to perform stamping. The telescopic stamping head extends when it is needed to perform stamping. The telescopic stamping head can adopt various structures, such as a cylinder with a telescopic function or a cam mechanism.

[0009] Preferably, the fixed plate is provided with an axial telescopic hole, the telescopic punch head is disposed in the telescopic hole, and a reset member is disposed in the telescopic hole, which is connected to the telescopic punch head. The telescopic hole serves as a moving channel for the telescopic punch head to extend and retract, guiding the extension and retraction of the telescopic punch head and ensuring the positional accuracy of the telescopic punch head; after the telescopic punch head extends, the reset member can independently reset the telescopic punch head, or it can play an auxiliary role when the telescopic punch head retracts automatically.

[0010] Preferably, the fixed plate has a radial groove, and a drive component for extending the telescopic punch head is disposed within the groove. The telescopic drive component includes a drive head and a cylinder. The cylinder is connected to the drive head and pushes the drive head to move within the groove. The drive head is connected to the tail end of the telescopic punch head. When the drive head moves forward, it pushes the telescopic punch head to extend. The drive component moves radially within the radial groove, and the drive head pushes the telescopic punch head to extend, while simultaneously transmitting the punching power from the fixed plate to the telescopic punch head.

[0011] Preferably, the upper end of the telescopic stamping head is provided with a wedge surface, and the drive head is provided with an inclined push part adapted to the wedge surface and a forward push part adapted to the upper surface of the telescopic stamping head. As the drive head moves radially, the inclined push part on the drive head cooperates with the wedge surface at the upper end of the telescopic stamping head, thereby pushing the telescopic stamping head to extend. After the telescopic stamping head extends to the end, the forward push part on the drive head contacts the upper surface of the telescopic stamping head, thereby transmitting stamping power. In order to ensure the cooperation between the wedge surface and the inclined push part, the upper end of the telescopic stamping head is designed as a non-rotating structure, or the outer surface of the telescopic stamping head is provided with an anti-rotation structure.

[0012] Preferably, the tilting device includes multiple sets of telescopic components. These telescopic components are located at the lower part of the frame and connected to the worktable. The multiple sets of telescopic components are symmetrical about the center of the worktable, and the number of telescopic components is an even number. The telescopic components work together to tilt the worktable to the required angle. The even number of telescopic components symmetrically arranged facilitates worktable tilt control.

[0013] Preferably, each telescopic component includes a telescopic part, a ball joint, and a connecting seat. The telescopic part is located at the lower part of the frame. The telescopic end of the telescopic part is connected to the ball seat, which is hinged to the ball joint. The other end of the ball joint is hinged to the connecting seat.

[0014] Preferably, the telescopic component uses a telescopic hydraulic cylinder, which is vertically positioned with its axis parallel to the telescopic axis of the upper stamping die. Using a telescopic hydraulic cylinder as the telescopic component supporting the worktable leverages the incompressibility of hydraulic oil and the high rigidity and lack of elastic deformation of the cylinder, thus achieving rigid support for the worktable. Therefore, when the hydraulic cylinder supports the worktable, it will not elastically sink due to load changes, ensuring the angular and height accuracy of the boss forming.

[0015] Preferably, the shaft hole positioning component includes a fixed column and a positioning ball column that are hinged to each other. The fixed column is located in the lower part of the frame. The upper end of the fixed column is a spherical seat, and the end of the positioning ball column is a ball head. The ball head cooperates with the spherical seat. A pressure cap is provided on the positioning ball column. The edge of the pressure cap presses against the edge of the shaft hole of the motor base plate. A position sensor is provided on the positioning ball column.

[0016] Preferably, a through hole is provided in the middle of the worktable, through which the shaft hole positioning component passes; a stamping cavity is provided on the worktable at the position corresponding to the motor base plate mounting hole, the diameter of the stamping cavity is larger than the diameter of the upper stamping die, and an elastic support component is provided in the stamping cavity; the elastic support component includes a support plate and an elastic support body, the upper end of the elastic support body is connected to the back of the support plate, and the lower end of the elastic support body is connected to the bottom of the stamping cavity.

[0017] The beneficial effects of the present invention are: 1. The present application supports the worktable by tilting device and tilts it according to the parameter requirements of the motor mounting plate. After the worktable is tilted, the motor base plate on the worktable tilts accordingly, so that the micro-protrusion processed by the stamping die meets the requirements. 2. A shaft hole positioning component is set in the middle of the worktable. After the motor base plate is placed and fixed on the worktable, the shaft hole positioning component positions the shaft hole of the worktable. When the worktable is tilted, it is tilted with the center of the shaft hole of the motor base plate as the reference. In this way, after the worktable is tilted, the height and angle of the micro-protrusion processed by the stamping die head are ensured that the motor axis meets the requirements after the motor mounting plate is installed and fixed, thereby reducing the time required for motor installation and adjustment, reducing installation and correction work, and improving installation efficiency. 3. In order to determine whether the tilt of the worktable meets the requirements, a position sensor is also installed on the shaft hole positioning post. The sensor can monitor the tilt angle of the shaft hole positioning post in real time, thereby ensuring that the micro-protrusion formed after the worktable is tilted meets the requirements. 4. An elastic support component is set on the worktable. After the motor base plate is placed and fixed, the elastic support component is located below the motor base plate and supports the area around the motor base plate mounting hole. When the upper stamping die is stamping, it clamps the area around the motor base plate mounting hole together with the upper stamping die. As the telescopic stamping head stamps, it always presses against the area around the motor base plate mounting hole to prevent deformation or jumping around the mounting hole and ensure that the forming of the micro boss meets the requirements. 5. The upper stamping die adopts a telescopic structure. The appropriate number of upper stamping dies can be selected according to actual needs. Based on the parameter requirements of the micro-bodies, a single upper stamping die can stamp individually, or multiple upper stamping dies can stamp simultaneously to ensure stamping efficiency. When the parameters of each micro-bodies are different, one upper stamping die is used for forming. When the parameters of two or more micro-bodies are the same, multiple upper stamping dies are used for forming simultaneously. When the worktable does not need to be tilted, the tilting device only serves a supporting function. All upper stamping dies work simultaneously, and the micro-bodies around the mounting holes of the motor base plate are formed simultaneously. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings. Example

[0020] like Figure 1 Figure 2 As shown, an automatic tilting angle stamping device for motor mount hole stamping surfaces includes a frame 1, a stamping upper die head located on the upper part of the frame, a worktable 3 located on the lower part of the frame, and a tilting device 6 located below the worktable in the lower part of the frame, which supports the worktable and allows it to tilt at any angle. A recessed cavity 27 with a shape adapted to the motor mount plate is provided on the worktable, a central boss 29 is provided at the center of the worktable, and a fixing device 4 is provided around the perimeter of the worktable. The fixing device adopts a quick-clamp structure, and its fixing end can extend into the upper part of the recessed cavity to press the motor mount plate. A control panel is provided on the side of the frame, and a hydraulic system 7 connected to the tilting device is provided on the lower side of the frame.

[0021] like Figure 3 Figure 4 As shown, the upper stamping die is a telescopic structure, including a stamping lifting main rod 8 and a fixed plate 9 located at the end of the lifting main rod. A telescopic stamping head 11 is mounted on the fixed plate, with its position corresponding to the mounting hole on the motor base plate. In this embodiment, there are five telescopic stamping heads. A stamping drive mechanism is located on the upper part of the frame, connected to the upper end of the lifting main rod. The stamping drive mechanism can be a cam drive mechanism or a hydraulic drive mechanism. In this embodiment, the motor base plate is made of 1.3mm thick aluminum alloy, and the diameter of the micro-protrusion is 8mm. Based on safety calculations, the stamping of a single micro-protrusion requires a stamping force of 8.4KN. Therefore, the total stamping power of the lifting main rod is 50.4KN, and a 10-ton hydraulic drive mechanism 2 is selected.

[0022] The fixed plate is disc-shaped and has an axial telescopic hole 20. A telescopic punch head is positioned within this hole, which is a stepped hole. The telescopic punch head extends downwards from the smaller diameter hole, and a cap 16 is provided at the larger diameter end of the telescopic hole. A guide head 18 is located at the upper end of the telescopic punch head, with its outer diameter matching the larger diameter of the telescopic hole. A reset element 19 is located within the telescopic hole and is connected to the telescopic punch head. The reset element is a spring, sleeved around the telescopic punch head. One end of the spring contacts the stepped portion of the telescopic hole, and the other end contacts the end of the guide head. A wedge surface 23 is located at the upper end of the guide head, with its edge passing through the center of the upper end of the guide head. Axial guide planes 24 are provided on both sides of the guide head's outer surface. A plane corresponding to the guide plane is located at the position of the telescopic hole, and these planes contact the guide planes to restrict the rotation of the telescopic punch head. A radial groove 15 is provided within the fixed plate, communicating with a telescopic hole. A driving component for extending the telescopic punch head is located within the groove. The telescopic driving component includes a driving head 17 and a cylinder 10. The cylinder is connected to the driving head and pushes the driving head to move within the groove. The driving head contacts the upper end of the guide head of the telescopic punch head. When the driving head moves forward, it pushes the telescopic punch head to extend. The driving head is square-shaped, and on the side facing the guide head, there is an inclined push part 22 adapted to the wedge surface and a forward push part 21 adapted to the upper surface of the telescopic punch head. When the cylinder retracts, under the action of the reset component, the telescopic punch head retracts back into the fixed plate, at which point the surface of the inclined push part contacts the wedge surface. Figure 8 As shown, when the telescopic punch head needs to extend, the cylinder pushes the drive head to move into the groove, and the oblique push part pushes the wedge surface, so that the telescopic punch head overcomes the elastic force of the reset part and extends out of the telescopic hole until the surface of the positive push part of the drive head contacts the axial upper end face of the guide head. The pressure of the cylinder is maintained, and the drive head is stationary in the fixed plate. Under the drive of the hydraulic drive mechanism, the fixed plate moves downward, and the lower end of the telescopic punch head contacts the periphery of the motor base plate mounting hole to perform micro-bore stamping.

[0023] like Figure 1 Figure 2 Figure 5As shown, the tilting device 6 includes multiple sets of telescopic components. These components are located at the lower part of the frame and connected to the worktable. The multiple sets of telescopic components are symmetrical about the center of the worktable, and the number of telescopic components is an even number. The telescopic components work together by rising and falling to drive the worktable to tilt as required. In this embodiment, there are 12 sets of telescopic components. Each telescopic component includes a telescopic member, a ball joint rod 13, and a connecting seat 12. The telescopic member is located at the lower part of the frame. The telescopic end of the telescopic member is connected to a ball seat 26. Ball heads 25 are provided at both ends of the ball joint rod. The ball head at the end of the ball joint rod is inserted into the ball seat to form a hinge, and the other ball head of the ball joint rod is inserted into the connecting seat to form a hinge. In this embodiment, the telescopic member uses a telescopic hydraulic cylinder 14. The telescopic hydraulic cylinder is vertically positioned, and its axis is parallel to the telescopic axis of the upper stamping die. The lower part of the frame has a mounting cavity for telescopic hydraulic cylinders. The telescopic hydraulic cylinders are housed within this cavity and kept vertically fixed. The hydraulic system is connected to the telescopic hydraulic cylinders via hydraulic pipelines. Control valves are installed on these pipelines; opening and closing these valves controls the raising and lowering of the telescopic hydraulic cylinders, thereby controlling the tilt angle of the worktable. The control valves include check valves and safety valves to ensure safe operation. In this embodiment, 12 telescopic hydraulic cylinders support the worktable, and 63mm diameter cylinders are selected based on a 10-ton load capacity.

[0024] like Figure 6 As shown, a through hole 34 is provided in the center of the worktable. A shaft hole positioning component is provided in the lower part of the frame. The shaft hole positioning component includes a fixed column 32 and a positioning ball column 31 that are hinged to each other. A position sensor is provided on the positioning ball column. The fixed column is located in the lower part of the frame. The upper end of the fixed column is a spherical seat, and the end of the positioning ball column is a ball head. The ball head mates with the spherical seat. The fixed column passes through the through hole. The axis of the fixed column coincides with the axis of the lifting main rod. The center of the ball head at the end of the positioning ball column is located at the center of the central boss of the worktable. The outer diameter of the spherical seat of the fixed column is smaller than the diameter of the through hole. The upper surface of the positioning ball column is provided with external threads. A pressure cap 30 is provided on the positioning ball column. The pressure cap is placed on the external threads of the positioning ball column. The motor base plate 28 is placed on the worktable. The shaft hole of the motor base plate corresponds to the through hole of the worktable. The edge of the pressure cap presses against the edge of the shaft hole of the motor base plate. The tilt of the worktable is based on the center of the shaft hole of the motor base plate.

[0025] like Figure 7As shown, a stamping cavity 37 is provided on the worktable at the position corresponding to the motor base plate mounting hole. The diameter of the stamping cavity is larger than the diameter of the telescopic stamping head, and an elastic support component is provided inside the stamping cavity. The elastic support component includes a support plate 35 and an elastic support body 36. The upper end of the elastic support body is connected to the back of the support plate, and the lower end of the elastic support body is connected to the bottom of the stamping cavity. The tilting device drives the worktable to tilt, and the upper stamping die head moves downward. The lower end of the extended telescopic stamping head contacts the periphery of the motor base plate mounting hole. The support plate and the end face of the telescopic stamping head clamp the periphery of the mounting hole. As the lower stamping die head continues to move downward, the stamping head forms a micro-protrusion around the motor base plate mounting hole.

[0026] The tilting device is achieved through the combined action of multiple telescopic components. The control panel inputs the installation parameters of the motor mounting plate and controls the lifting and lowering of the corresponding telescopic components by setting the control program. The control panel also controls the extension and retraction of the corresponding cylinders, thereby causing the required telescopic punch head to extend. The position sensor on the positioning ball column provides real-time feedback on the tilt angle of the worktable.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
