Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to a motor riveting device. Background Technology

[0002] A geared motor is a device that converts electrical energy into mechanical energy. It consists of two parts: a motor and a gearbox. The motor provides the power source, while the gearbox is responsible for speed reduction and torque output.

[0003] The rotor is a key component of the motor. During the motor assembly process, after the rotor is pressed into the protective housing, the protective housing needs to be riveted to fix the rotor in place.

[0004] In existing motor production, the riveting of protective housings requires not only riveting multiple points on the protective housings separately, but also fixing the gearbox motor. This involves many moving mechanisms, a lengthy process, and low production efficiency.

[0005] Therefore, there is an urgent need for a motor riveting device to solve the above-mentioned technical problems. Summary of the Invention

[0006] Based on the above, the purpose of this invention is to provide a motor riveting device that can simultaneously rivet and fix a gearbox motor through a single downward extension action of a single riveting power mechanism, thereby shortening the operation process, improving production efficiency, and reducing equipment costs.

The power block is provided with an inclined structure, which is inclined towards the riveting station in the vertical upward direction.

[0017] A guide block is slidably mounted on the power seat in a horizontal direction. The guide block is connected to the inclined structure. When the power block moves downward, it drives the guide block to extend horizontally toward the riveting station.

[0018] A riveting block is installed at the end of the guide hole facing the riveting station and is used to rivet the protective shell.

[0019] As an optional technical solution for the motor riveting device, the power seat is provided with a horizontal first clearance hole on the side facing the riveting station. The first clearance hole is connected to the lifting hole. The power block is provided with a horizontal through second clearance hole.

The detection hole extends in the same direction as the first clearance hole and communicates with the lifting hole. The riveting assembly also includes a distance sensor, which is fixed to the power seat. The distance sensor can detect the horizontal movement distance of the guide block through the detection hole.

[0022] As an optional technical solution for the motor riveting device, the riveting assembly further includes an elastic reset member, one end of which is connected to the power base and the other end of which is connected to the power block. The elastic reset member has a tendency to pull the power block upward.

[0023] As an optional technical solution for the motor riveting device, two riveting mechanisms are provided, and the two riveting mechanisms are symmetrically arranged on both sides of the horizontal direction of the riveting station.

[0030] The motor riveting device provided by this invention uses a riveting power mechanism to drive a lower support plate downwards. A pressure box assembly and a top column are mounted on the lower surface of the lower support plate. As the lower support plate moves downwards, the top column pushes the riveting assembly downwards, causing it to extend horizontally towards the motor at the riveting station, thereby riveting the protective housing.

[0043] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This embodiment provides a motor riveting device that acts on the gearbox motor 100 to rivet the protective housing of the motor portion, so that the upper edge of the protective housing forms an inwardly recessed limiting part, thereby fixing the rotor therein. Figures 1-4 As shown, the motor riveting device includes a base, a riveting power mechanism 1, a lower support plate 2, a pressure box assembly 3, and a riveting mechanism. The base includes a bottom plate 10, a top plate 20, and four pressure shaft columns 30. The top plate 20 is mounted on top of the bottom plate 10 via the four pressure shaft columns 30.

[0045] Furthermore, such as Figure 1 and Figure 2 As shown, the riveting power mechanism 1 is located on the top plate 20, and its output end is vertically extended downwards. The lower support plate 2 is connected to the output end of the riveting power mechanism 1. The pressure box assembly 3 is installed on the lower surface of the lower support plate 2. The pressure box assembly 3 can move downwards with the lower support plate 2 to press against the gearbox. The riveting mechanism includes a top column 4 and a riveting assembly 5. The top column 4 is installed on the lower surface of the lower support plate 2, and the riveting assembly 5 is located on the bottom plate 10. The top column 4 can move downwards with the lower support plate 2 to push the riveting assembly 5 downwards, so that the riveting assembly 5 extends horizontally toward the motor at the riveting station, thereby riveting the protective housing.

[0046] Specifically, the motor riveting device provided in this embodiment drives the lower support plate 2 to move downward through the riveting power mechanism 1. A pressure box assembly 3 and a top column 4 are installed on the lower surface of the lower support plate 2. As the lower support plate 2 moves downward, the top column 4 pushes the riveting assembly 5 downward, causing it to extend horizontally towards the motor at the riveting station, thereby riveting the protective housing. Simultaneously, the pressure box assembly 3 moves downward and presses down on the gearbox from the top, thus fixing and limiting the overall position of the gearbox motor 100 and preventing it from shifting during the riveting process. In summary, the motor riveting device provided by this invention can simultaneously rivet and fix the gearbox motor 100 through a single downward extension action of the riveting power mechanism 1, shortening the operation process, improving production efficiency, and reducing equipment costs.

[0047] For example, such as Figure 1 and Figure 2As shown, the riveting power mechanism 1 includes a riveting drive component 11, a linear bearing 12, and a downward pressing guide rod 13. The riveting drive component 11 is mounted on the top plate 20. The output end of the riveting drive component is vertically inserted into the top plate 20 and connected to the downward pressing support plate 2. The linear bearing 12 is vertically inserted into the top plate 20. The downward pressing guide rod 13 is inserted through the linear bearing 12, and the lower end of the downward pressing guide rod 13 is connected to the downward pressing support plate 2.

[0048] For example, the riveting drive 11 is a linear electric actuator. In other embodiments, the riveting drive 11 may also be other linear drive components such as cylinders or hydraulic cylinders.

[0049] For example, such as Figure 1 and Figure 2 As shown, the riveting drive component 11 has two linear bearings 12 and two downward guide rods 13 at its two ends in the horizontal direction. The upper ends of the two adjacent downward guide rods 13 are connected by a fixing rod plate 14. The fixing rod plate 14 can connect the two adjacent downward guide rods 13 to improve the overall rigidity, and can also mechanically limit the downward movement limit of the downward guide rods 13 to improve reliability.

[0050] For example, such as Figure 1 and Figure 2 As shown, the motor riveting device also includes a linear displacement sensor 8 and a pressing induction bracket 9. The linear displacement sensor 8 is installed in the first detection clearance hole 201 on the top plate 20, and the first detection clearance hole 201 vertically penetrates the top plate 20. The pressing induction bracket 9 is installed on the top surface of the lower pressing support plate 2, and the pressing induction bracket 9 passes through the first detection clearance hole 201. When the pressing drive component is fully retracted, the linear displacement sensor 8 detects the pressing induction bracket 9. The linear displacement sensor 8 and the pressing induction bracket 914 can automatically detect whether the riveting drive component 11 extends downward and whether the riveting drive component 11 retracts into place.

[0051] For example, the linear displacement sensor 8 employs an optical proximity switch.

[0052] For example, such as Figure 2As shown, the riveting power mechanism 1 also includes a floating joint 15, a connecting flange 16, a pressure sensor 17, a connecting plate 18, and multiple support columns 19. The floating joint 15 is installed at the output end of the riveting drive component 11. The lower end of the floating joint 15 is provided with a boss. The connecting flange 16 is sleeved on the top of the boss. The pressure sensor 17 is installed on the top of the lower support plate 2 through the connecting plate 18. The connecting flange 16 and the connecting plate 18 are connected by multiple support columns 19. When the riveting drive component 11 extends downward, the floating joint 15 can press against the pressure sensor 17. Specifically, when the riveting drive component 11 begins to extend downwards, the floating joint 15 and the pressure sensor 17 are spaced apart. The floating joint 15 drives the lower support plate 2 to move downwards through the connecting flange 16, connecting plate 18, and support column 19. At this time, the detection value of the pressure sensor 17 is zero. When the pressure box assembly 3 abuts against the gearbox from above, the riveting drive component 11 continues to extend downwards, and the distance between the floating joint 15 and the pressure sensor 17 gradually decreases until they are completely in contact. At this time, the detection value of the pressure sensor 17 gradually increases until the riveting operation is completed or the detection value of the pressure sensor 17 reaches the preset value, at which point the riveting drive component 11 stops extending downwards. The setting of the pressure sensor 17 can automatically detect the extension amount of the riveting drive component 11 and avoid excessive tightening pressure, thereby improving reliability and fault tolerance.

[0053] For example, such as Figure 3 and Figure 4 As shown, the riveting assembly 5 includes a power base 51, a power block 52, a guide block 53, and a riveting block 54. The power base 51 is mounted on the base plate 10 via a support plate 59 and a support block 591. The power base 51 has a lifting hole 511 with at least an upper opening, which extends vertically. The power block 52 slides vertically through the lifting hole 511 and can extend from the upper opening of the lifting hole 511 to abut against the top post 4. The power block 52 has an inclined structure that is inclined vertically upward toward the riveting station. The guide block 53 slides horizontally on the power base 51 and is connected to the inclined structure. When the power block 52 moves downward, it drives the guide block 53 to extend horizontally toward the riveting station. The riveting block 54 is installed at the end of the guide hole facing the riveting station. The front end of the riveting block 54 has a wedge-shaped riveting part for riveting the protective housing.

[0054] Specifically, when the power block 52 moves downward along the lifting hole 511 under the action of the top column 4, the guide block 53 extends horizontally toward the riveting station under the action of the inclined structure, so that the wedge-shaped riveting part at the front end of the riveting block 54 presses against and rivets the protective sleeve, thereby realizing the conversion from vertical action to horizontal action, so as to realize riveting in the horizontal direction. Compared with the scheme of setting the riveting power component horizontally, it saves more horizontal space.

[0055] For example, such as Figure 4 As shown, the power seat 51 has a horizontal first clearance hole 512 on the side facing the riveting station. The first clearance hole 512 is connected to the lifting hole 511. The power block 52 has a horizontal through second clearance hole 521. The first clearance hole 512 and the second clearance hole 521 are connected to each other. The guide block 53 is slidably disposed in the first clearance hole 512 and the second clearance hole 521.

[0056] For example, such as Figure 4 As shown, the inclined structure is configured as an inclined guide hole 522, which is connected to the second clearance hole 521. A guide roller 55 is rotatably connected to the side wall of the guide block 53 by a pin. The guide roller 55 is inserted into the inclined guide hole 522 and can roll along the inclined guide hole 522.

[0057] For example, the power block 52 is provided with inclined guide holes 522 on two opposite side walls, and the guide block 53 is rotatably connected to two opposite side walls. The two guide rollers 55 are rolled in a one-to-one correspondence with the two inclined guide holes 522 to improve the stability of the horizontal movement of the guide block 53 and ensure the riveting quality.

[0058] For example, such as Figure 3 As shown, the riveting assembly 5 also includes an elastic reset member 57. One end of the elastic reset member 57 is connected to the power seat 51, and the other end is connected to the power block 52. The elastic reset member 57 has a tendency to pull the power block 52 upward to drive the power block 52 to reset upward, while simultaneously driving the riveting block 54 to reset and retract.

[0059] For example, such as Figure 3 As shown, the elastic reset member 57 is a tension spring. A first fastening screw 571 is fixed on the outer side wall of the power seat 51. A lifting clearance hole 514 extending vertically is also provided on the same side wall of the power seat 51. A second fastening screw 572 is fixed on the side wall of the power block 52. The second fastening screw 572 extends out from the lifting clearance hole 514. The two ends of the elastic reset member 57 are respectively connected to the first fastening screw 571 and the second fastening screw 572.

[0060] For example, such as Figure 3 and Figure 4As shown, the power base 51 has a detection hole 513 on the side opposite to the first clearance hole 512. The detection hole 513 extends in the same direction as the first clearance hole 512 and communicates with the lifting hole 511. The riveting assembly 5 also includes a distance sensor 56, which is fixed to the power base 51. The distance sensor 56 can detect the horizontal movement distance of the guide block 53 through the detection hole 513, thereby detecting whether the guide block 53 has extended into place. Furthermore, the coordinated arrangement of the distance sensor 56, the linear displacement sensor 8, and the pressure sensor 17 detects from multiple points whether the power is smoothly transmitted to the riveting block 54, so that the riveting block 54 extends into place normally. If the motor riveting device malfunctions, the problem can be quickly identified by the detection values ​​of the distance sensor 56, the linear displacement sensor 8, and the pressure sensor 17.

[0061] For example, distance sensor 56 employs a photoelectric sensor.

[0062] For example, such as Figure 3 and Figure 4 As shown, the power seat 51 is connected to a guide sleeve 58 on the side facing the riveting station. The guide sleeve 58 has a riveting relief hole that extends in the same direction as and communicates with the first relief hole 512. The guide block 53 is slidably placed in the riveting relief hole.

[0063] For example, such as Figure 1 and Figure 2 As shown, the motor riveting device also includes a linear module 7 and a motor mold 6. The linear module 7 extends horizontally and passes through the riveting station. The motor mold 6 is installed at the output end of the linear module 7. The motor mold 6 is used to accommodate the gearbox motor 100 to be riveted. The linear module 7 can drive the motor mold 6 to reach or leave the riveting station.

[0064] For example, the linear module 7 adopts the linear motor module in the prior art, and its specific structure will not be described in detail here.

[0065] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
