[0002] A motor, also known as an electric motor, is a device that can convert electrical energy into mechanical energy. The motor is mainly composed of a casing, stator, rotor, brushes, end covers, shafts, bearings and other components. During the motor assembly process, a riveting device is required to rivet the motor's bearings, rotor, stator, casing and other assembly components.

[0003] When processing the bearing assembly of the motor, it is usually necessary to put the motor bearing workpiece on the support, and then use the cylinder to drive the punch head to punch and rivet the bearing workpiece. However, in the actual processing process, when the punch head contacts the bearing, due to the mutual squeezing and friction, heat will be generated, which will increase the temperature of the punch head, resulting in weakening of its surface hardness and increased wear, thereby affecting the service life of the punch head. At the same time, the punch head is prone to thermal deformation when it is heated, which affects the accuracy and stability of the punch head, and then affects the quality of the bearing workpiece, which is not conducive to the assembly and production of the motor. Utility Model Content

[0004] The utility model aims to solve the problem that during the use of the current riveting device, the punch head is prone to generate heat, resulting in an increase in the temperature of the punch head, which not only affects the service life of the punch head but also affects the processing quality of the workpiece, and proposes a riveting device for assembling a motor.

[0025] Example:

[0026] Reference Figure 1-Figure 5 The embodiment of the utility model provides a riveting device for assembling a motor, comprising a machine base 1 with a bracket 2 installed, and also comprising: a punch head 3, installed on the bracket 2, wherein a driving part for driving the punch head 3 to move up and down is provided on the bracket 2, a turntable 4 is rotatably connected to the top of the machine base 1, and a plurality of supports 5 are fixedly installed on the top of the turntable 4, wherein the number of the supports 5 is 8 and they are arranged in a ring shape on the top of the turntable 4, and the bottom end of the punch head 3 faces the top end of the support 5; a pair of blowing hoods 6, both installed on the bracket 2, wherein the blowing port of the blowing hood 6 faces the punch head 3, and an air supply part for making the blowing hood 6 blow intermittently is provided on the bracket 2.

[0027] Specifically, during use, through the setting of the driving part, the mounting plate 32 and the punch head 3 can be driven to move up and down, so as to punch and rivet the bearing workpiece on the support 5. At the same time, through the setting of the air supply part, the surface of the punch head 3 can be blown each time it moves upward and resets after punching, so as to blow away the heat generated by the punching of the surface of the punch head 3, thereby achieving the effect of cooling down and preventing the punch head 3 from continuously punching and causing its temperature to rise, thereby accelerating wear or deformation. It can not only improve the service life of the punch head 3, but also improve the processing quality of the workpiece, which is beneficial to the assembly and production of the motor. In addition, through the coordinated use of the turntable 4, multiple supports 5 and the punch head 3, it is convenient to continuously punch the bearing workpiece, thereby greatly improving the assembly and production efficiency of the motor.

[0028] The driving part includes a cylinder 31 fixedly mounted on the bracket 2 , an output end of the cylinder 31 is fixedly connected to a mounting plate 32 , and the punch head 3 is fixedly mounted on the bottom of the mounting plate 32 .

[0029] Specifically, when in use, the cylinder 31 is started, and the output end of the cylinder 31 drives the mounting plate 32 and the punch head 3 to move up and down, so that the bearing workpiece on the support 5 can be punched and riveted.

[0030] The air delivery part includes a telescopic airbag 61 fixed on the mounting bracket 2, the bottom end of the telescopic airbag 61 is fixedly connected to the top of the mounting plate 32, the top of the telescopic airbag 61 is connected to an air inlet pipe 62, and the bottom of the telescopic airbag 61 is connected to the blowing hood 6 through a hose 63, and a one-way valve is installed in the air inlet pipe 62 and the hose 63.

[0031] Specifically, during use, when the mounting plate 32 moves downward, the telescopic airbag 61 is stretched to allow outside air to enter the telescopic airbag 61; when the mounting plate 32 moves upward to reset, the telescopic airbag 61 is compressed to allow the air in the telescopic airbag 61 to continuously blow toward the surface of the punch head 3 through the hose 63 and the blowing hood 6, so that the surface of the punch head 3 can be blown to cool down each time the punch head 3 is reset upward after punching, and through the setting of the one-way valve, the air inlet pipe 62 can only take in air, while the hose 63 can only exhaust air.

[0032] A support plate 7 is fixedly connected to the bracket 2, and a shaft rod 71 is rotatably connected to the support plate 7. A torsion spring 75 is installed between the shaft rod 71 and the support plate 7. The blow hood 6 is fixedly connected to one end of the shaft rod 71, and a vertical plate 72 is fixedly connected to the bracket 2; a plurality of arc blocks 73 are fixedly connected to the surface of the vertical plate 72, and the number of the arc blocks 73 is 10-12, preferably 10, and are linearly arranged longitudinally on the vertical plate 72. A cam 74 is fixedly connected to the end of the shaft rod 71 away from the blow hood 6. When the punch head 3 moves up and down, the cam 74 will slide over the plurality of arc blocks 73 in sequence.

[0033] Specifically, during use, when the cylinder 31 drives the mounting plate 32 to move up and down, it also drives the support plate 7, the blowing hood 6 and the shaft rod 71 to move synchronously, so that the cam 74 slides over multiple arc blocks 73 in sequence. During the sliding process, when the top angle of the cam 74 contacts and squeezes the arc surface of the arc block 73, the cam 74 drives the shaft rod 71 and the blowing hood 6 to rotate, and twists the torsion spring 75. When the top angle of the cam 74 disengages from the arc block 73, under the elastic force of the torsion spring 75, the cam 74 and the blowing hood 6 are quickly rotated and reset. By sliding multiple arc blocks 73 in sequence by the cam 74, the blowing hood 6 can be driven to swing continuously to expand the blowing range of the blowing hood 6 and make the wind blow more evenly on the surface of the punching head 3, thereby further improving the cooling effect on the punching head 3.

[0034] A motor 41 is fixedly installed inside the base 1, and a rotating rod 42 is rotatably connected inside the base 1. The surface of the rotating rod 42 and the output end of the motor 41 are fixedly connected with mutually meshing bevel gears 43, and the top end of the rotating rod 42 is fixedly connected to the bottom of the turntable 4.

[0035] Specifically, during the upward movement and resetting process of the punch head 3, when punching the bearing workpiece on the next support 5, by starting the motor 41, the output end of the motor 41 drives the bevel gear 43 and the rotating rod 42 to rotate, thereby driving the turntable 4 to rotate 45° and drive the next support 5 to move to the bottom of the punch head 3 so that the punch head 3 can be punched again.

[0036] A filter element 8 is detachably mounted at the air inlet of the air inlet pipe 62 .

[0037] Specifically, by providing the filter element 8 , the air entering the telescopic airbag 61 can be filtered to prevent dust and impurities in the air from entering the telescopic airbag 61 .

[0038] The specific working process is as follows: when the riveting device for assembling the motor is used, the bearing assembly of the motor is first sleeved on the multiple supports 5 on the top of the turntable 4 in sequence, and then the cylinder 31 is started. The output end of the cylinder 31 drives the mounting plate 32 and the punch head 3 to move downward, so as to perform stamping and riveting on the bearing workpiece on the support 5. At the same time, when the mounting plate 32 moves downward, the telescopic airbag 61 is stretched to allow the outside air to enter the telescopic airbag 61. When a bearing workpiece is stamped, the cylinder 31 drives the mounting plate 32 and the punch head 3 to move upward and reset. The telescopic airbag 61 is compressed through the mounting plate 32, so that the air in the telescopic airbag 61 is continuously blown toward the surface of the punch head 3 through the hose 63 and the blowing hood 6, and the surface of the punch head 3 can be blown each time the punch head 3 moves upward and resets after punching, so as to blow away the heat generated by the punching of the surface of the punch head 3, thereby achieving the effect of cooling, preventing the punch head 3 from continuously punching and causing its temperature to rise, thereby accelerating wear or deformation, which can not only improve the service life of the punch head 3, but also improve the processing quality of the workpiece, which is beneficial to the assembly and production of the motor;

[0039] During the upward movement and resetting process of the punch head 3, when punching the bearing workpiece on the next support 5, the turntable 4 is driven to rotate 45° and the next support 5 is driven to move to the bottom of the punch head 3, and then the punch head 3 is driven by the cylinder 31 again to continuously punch and rivet the bearing workpiece on the support 5. Similarly, the worker only needs to remove the stamped and riveted bearing workpiece and replace it with a bearing workpiece to be processed. By using the turntable 4, multiple supports 5 and the punch head 3 in coordination, the bearing workpiece can be conveniently punched continuously, thereby greatly improving the assembly production efficiency of the motor.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
