Description

Technical Field

[0001] The present application relates to the technical field of motor stator and rotor processing, and in particular to an automatic lamination mechanism for a high-speed stamping die for a motor stator and rotor. Background Art

[0002] The stator and rotor are the core components of the motor. The main function of the stator is to generate a rotating magnetic field, providing the magnetic field environment required for the motor to work. The rotor rotates under the action of the rotating magnetic field, converting electrical energy into mechanical energy, thereby driving the load to operate. During the motor production process, the lamination quality of the stator and rotor directly affects the performance and efficiency of the motor. The automatic lamination mechanism can achieve high-speed and high-precision lamination operations, greatly improving production efficiency and product quality. Lamination usually refers to the process of placing pieces of punched sheets together in a certain order and direction.

[0003] However, the stacking mechanism of the motor stator and rotor stamping die in the existing technology cannot ensure stable and controllable intervals for the discharge of most sheets, and may not be able to ensure the time interval for discharge, making it difficult for subsequent processing to match the discharge rhythm, affecting production efficiency. If the discharge speed and time interval cannot be adjusted according to actual production needs, the production process lacks flexibility and is difficult to adapt to different production tasks and process requirements. In addition, the stacking mechanism of the motor stator and rotor stamping die in the existing technology cannot make up for the uneven thickness of the raw materials. The existing technology usually cannot effectively handle the uneven thickness of the punching sheets during the stacking process. When the raw materials are uneven in thickness, the stacked products are prone to defective products with one side thick and the other side thin, which greatly reduces the yield rate.

[0004] In response to the above-mentioned related technologies, the inventors proposed an automatic lamination mechanism for a high-speed stamping die for a motor stator and rotor to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0031] Example 1

[0032] An automatic lamination mechanism for high-speed stamping die of motor stator and rotor, Figure 1-2 , including a lower plate 1, an upper plate 2 is fixed on the upper end of the lower plate 1, a bracket 3 is fixed on one side of the upper end of the upper plate 2, a discharge pipe 4 is penetrated on one side of the upper end of the upper plate 2, a cylinder 5 is fixed on the other side of the upper end of the upper plate 2, the output end of the cylinder 5 passes through the upper plate 2 and is fixed with a lifting plate 51, four positioning columns 53 are fixed on the upper end of the lifting plate 51, and the upper ends of the four positioning columns 53 are connected with the upper plate 2, a stacking column 52 is fixed on the lower end of the lifting plate 51, a support plate 6 is slidably provided on the upper end of the lower plate 1, a support box 7 is fixed on the upper end of the support box 7, and a mold tube is rotatably provided on the upper end of the support box 7 8. The lower plate 1 and the upper plate 2 constitute the main body of the frame. Multiple punches are stacked in the discharge pipe 4. The discharge is controlled by the discharge control structure. Multiple punches fall into the mold tube 8. The support plate 6 can slide to drive the mold tube 8 to move through the support box 7. The cylinder 5 serves as a driving structure for the stacking process. Specifically, the cylinder 5 is started, and the output end pushes the lifting plate 51 down. The stacking column 52 at the lower end of the lifting plate 51 then drops down to perform a stacking operation on the material in the mold tube 8. The four positioning columns 53 at the upper end of the lifting plate 51 ensure the stability of the lifting plate 51 during the lifting process. The overall structural design is simple and reliable.

[0033] Reference Figure 2The first servo motor 32 is provided with a first half-gear 34 on one end of the bracket 3, and a first half-gear 34 is provided on the outer surface of the bracket 3. The first half-gear 34 is rotated by the bracket 3. A connecting rod 35 is fixed on the outer surface of the first half-gear 34. A sliding column 36 is provided on one end of the connecting rod 35, and the outer surface of one end of the sliding column 36 is slidably connected with the inner wall of the reciprocating groove 33. The outer surface of the first half-gear 34 is meshed with a toothed plate 37. The lower end of the toothed plate 37 is fixed with a baffle 38. A limit plate 39 is fixed on the upper end of the upper plate 2. The lower end of the baffle 38 is slidably connected to the limit plate 39. One end of the baffle 38 is connected to one side of the outer surface of the discharge pipe 4. When the discharge control is required, the mold tube 8 moves to the bottom of the discharge hook 4, the first servo motor 32 is started, driving the shaft 31 to rotate on the bracket 3, and the shaft 3 The reciprocating groove 33 on the outer surface of the first half face gear 34 rotates accordingly, causing the sliding post 36 to slide in the reciprocating groove 33. Since one end of the sliding post 36 is connected to the connecting rod 35, which is fixed to the upper side of the outer surface of the first half face gear 34, the rotation of the reciprocating groove 33 drives the first half face gear 34 to rotate intermittently. When the first half face gear 34 rotates, it pushes the tooth plate 37 to move. The baffle plate 38 at the lower end of the tooth plate 37 slides along the limit plate 39. When the baffle plate 38 moves out of the discharge pipe 4, the discharge pipe is opened. Then, with the reverse movement of the first half face gear 34, the baffle plate 38 blocks the discharge pipe 4, completing the outflow of one sheet. The sheet falls into the mold tube 8 for stacking. Through the cooperation of the first servo motor 32, the rotating shaft 31, the first half face gear 34, the tooth plate 37 and the baffle plate 38, the sheet units in the discharge pipe 4 can be accurately controlled to be discharged in sequence. The discharge time intervals are uniform, controllable and stable, which facilitates the automatic lamination process and improves production efficiency.

[0034] Reference Figure 3 A lifting plate 81 is provided on the lower inner wall of the mold tube 8, and lifting grooves 82 are provided on both sides of the outer surface of the mold tube 8 for use with the lifting plate 81. The design of the lifting plate 81 and the lifting groove 82 in the mold tube 8 facilitates the removal of the stacked discs in the mold tube 8 and improves the convenience of operation.

[0035] The implementation principle of the embodiment of the present application is as follows: the lower plate 1 and the upper plate 2 constitute the frame body, and multiple punches are stacked in the discharge pipe 4. The discharge is controlled by the discharge control structure, and multiple punches fall into the mold tube 8. The support plate 6 can slide to drive the mold tube 8 to move through the support box 7. The cylinder 5 serves as a driving structure for the stacking processing. Specifically, the cylinder 5 is started, and the output end pushes the lifting plate 51 down, and the stacking column 52 at the lower end of the lifting plate 51 drops accordingly, and the material in the mold tube 8 is stacked. The four positioning columns 53 at the upper end of the lifting plate 51 ensure the stability of the lifting plate 51 during the lifting process. The overall structural design is simple and reliable to use.

[0036] When discharge control is required, when the mold tube 8 moves to the bottom of the discharge hook 4, the first servo motor 32 is started, driving the rotating shaft 31 to rotate on the bracket 3, and the reciprocating groove 33 on the outer surface of the rotating shaft 31 rotates accordingly, causing the sliding column 36 to slide in the reciprocating groove 33. Since one end of the sliding column 36 is connected to the connecting rod 35, and the connecting rod 35 is fixed to the upper side of the outer surface of the first half-face gear 34, the rotation of the reciprocating groove 33 will drive the first half-face gear 34 to rotate intermittently. When the first half-face gear 34 rotates, it pushes the gear plate 37 to move, and the lower end of the gear plate 37 The baffle 38 slides along the limit plate 39. When the baffle 38 moves out of the discharge pipe 4, the discharge pipe opens. Then, with the reverse movement of the first half-face gear 34, the baffle 38 blocks the discharge pipe 4, completing the outflow of one of the sheets. The sheet falls into the mold tube 8 for stacking. Through the cooperation of the first servo motor 32, the rotating shaft 31, the first half-face gear 34, the tooth plate 37 and the baffle 38, the sheet units in the discharge pipe 4 can be accurately controlled to discharge in sequence. The time intervals for discharge are the same, controllable and stable, which is convenient for automatic lamination processing and improves production efficiency.

[0037] The design of the lifting plate 81 and the lifting groove 82 in the mold tube 8 facilitates the removal of the stacked discs in the mold tube 8 and improves the convenience of operation.

[0038] Example 2

[0039] The difference between this embodiment and embodiment 1 is that:

[0040] Reference Figure 3, a second servo motor 71 is provided on one side of the upper end of the support plate 6, and a driving column 72 is fixedly provided at the output end of the second servo motor 71. One end of the driving column 72 passes through the support box 7 and is fixedly provided with a second half-face gear 73. The outer surface of the second half-face gear 73 is meshed with a side gear 74. The lower end of the side gear 74 is rotatably connected to the lower inner wall of the support box 7. The radius of the side gear 74 is twice the radius of the second half-face gear 73. A pillar 75 is fixedly provided at the upper end of the side gear 74. The upper end of the pillar 75 passes through the support box 7 and is fixedly connected to the mold tube 8. When the sheet falls into the mold tube 8 from the discharge pipe 4, the second servo motor 71 is started, driving the driving column 72 to rotate, and the driving column The second half-face gear 73 at one end of 72 rotates accordingly, driving the side gear 74 to rotate, and the support 75 at the upper end of the side gear 74 drives the mold tube 8 to rotate, thereby realizing the rotation of the mold tube 8. Through the cooperation of the second servo motor 71, the driving column 72, the second half-face gear 73, the side gear 74 and the support 75, the mold tube 8 rotates once every time a punching sheet falls, so that the uneven thickness of the punching sheets can compensate for each other during the stacking process, greatly reducing the problem of defective products with one side thick and the other side thin due to the uneven thickness of the raw materials, thereby significantly improving the overall quality of the punching sheets, ensuring that the products meet higher quality standards, greatly reducing the defective rate, and improving the yield rate of the punching sheets.

[0041] Reference Figure 3 A guide rail 61 is fixedly provided at the upper end of the lower plate 1. Two electric sliders 62 are provided on the upper end of the guide rail 61 when it slides. The upper ends of the two electric sliders 62 are fixedly connected to the support plate 6. The setting of the guide rail 61 and the electric slider 62 enables the support plate 6 to flexibly adjust its position, thereby driving the mold tube 8 to move to a suitable position for operation, which improves the adaptability and operational convenience of the equipment.
