Description

Technical Field

[0001] This utility model relates to the field of riveting device technology, and in particular to a riveting device for manufacturing motor fan covers. Background Technology

[0002] In the field of motor manufacturing, the stability and reliability of motor shrouds directly affect the heat dissipation performance and operational safety of motors. As a key link in motor shroud manufacturing, the degree of automation and adaptability of riveting equipment plays a decisive role in production efficiency and product quality. With the diversification of motor models and the rapid iteration of market demands, the limitations of traditional riveting devices in dealing with shrouds of different specifications are becoming increasingly apparent. There is an urgent need for a new type of riveting equipment that can improve operational convenience and be compatible with multiple workpiece models to meet the needs of modern manufacturing for flexible production and high-precision machining.

[0003] Existing motor fan cover riveting devices typically use fixed-specification mechanical clamps to position and hold the workpiece. The clamp structure is mostly a rigid frame of a single size, relying on manual adjustment or replacement of the clamps to adapt to fan covers of different curvatures and sizes. The technical principle of this type of device is mainly based on mechanical limiting and rigid clamping, and the workpiece is fixed by fixing bolts or manual knobs. Moreover, the metal debris generated during the riveting process mostly relies on manual cleaning or simple brush cleaning.

[0004] However, the existing technology has the following problems: due to the lack of multi-dimensional adjustment capability and adaptive clamping function of the fixture, when different specifications of motor fan covers need to be processed, the operator needs to spend a lot of time disassembling and replacing the entire set of fixtures. Moreover, the fixed workpiece is prone to positioning deviation due to insufficient fixture adaptability, which in turn affects the riveting accuracy. This problem of inconvenient fixing and poor adaptability not only leads to low riveting efficiency, but also increases the equipment debugging cost and workpiece loss rate of enterprises. It is difficult to meet the requirements of modern motor manufacturing industry for efficient production and fine processing. Therefore, a riveting device for motor fan cover manufacturing is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 An embodiment of this utility model is provided: a riveting device for manufacturing a motor fan cover, including a base plate 1, the base plate 1 is made of steel plate, a support column 2 is fixedly connected to the top of the base plate 1 for supporting the riveting assembly and the fixing assembly, a riveting assembly is provided above the side wall of the support column 2, and a fixing assembly is provided below the riveting assembly for positioning and clamping the motor fan cover.

[0035] The fixing assembly includes a base 6 made of cast iron. A rotating disk 7, made of aluminum alloy, is rotatably connected to the base 6 via bearings. A fixed disk 8 is located on the side of the rotating disk 7 and is fixedly connected to the base 6 at its bottom. Multiple sliding grooves 14 are formed on the side wall of the rotating disk 7, arranged at a 45° angle to guide the movement of the guide column 12. A power assembly is located on the other side wall of the rotating disk 7, driving its rotation. The power assembly is located inside the base 6. Multiple guide grooves 9 are formed on the side wall of the fixed disk 8, each containing a sliding groove 10. The guide grooves 9, 10, and 14 are all circumferentially distributed with equal spacing. The guide grooves 9 restrict the slider 11. The direction of movement is controlled by slide groove 14, which restricts the movement of guide post 12. Sliding sliders 11, made of mold steel, are slidably connected inside guide groove 9. Guide posts 12, made of cylindrical pins and hardened, are fixedly connected to the bottom of slider 11. Guide posts 12 are slidably connected inside slide groove 10 and slide groove 14 to transmit the rotational motion of the rotating disk 7 to slider 11. A clamping plate 13, made of spring steel and with anti-slip texture on its inner surface, is fixedly connected to the top of slider 11 to hold the motor fan cover. A fixing plate 5, made of thick steel plate, is fixedly connected to the side wall of base 6 by welding to the side wall of support post 2 to reinforce base 6. For structural stability, a drive motor is installed on its side wall to drive the base 6 to rotate, thereby rotating the clamped motor fan cover, facilitating subsequent riveting operations on the motor fan cover shell. The power component includes an electric actuator 16, which is existing technology and will not be described in detail here. A connecting seat 17 is fixedly connected to the bottom of the electric actuator 16. The connecting seat 17 consists of a two-section rotatable rocker arm made of cast iron. The side wall of the connecting seat 17 is fixedly connected to the inner wall of the base 6. A connecting block 15 is fixedly connected to the output end of the electric actuator 16. The connecting block 15 is identical to the connecting seat 17 and is used to transmit the linear motion of the actuator to the rotating disk 7. The side wall of the connecting block 15 is fixedly connected to the outer wall of the rotating disk 7. The riveting assembly includes a riveter 4, which uses a pneumatic riveter. The riveting machine uses a riveting device 4, which is existing technology and will not be described in detail here. The side wall of the riveting device 4 is fixedly connected to the side wall of the support column 2. A control console 3 is provided on the side of the riveting device 4. The control console 3 is made of ABS engineering plastic and integrates a PLC control system and operation buttons for inputting control commands. The control console 3 is existing technology and will not be described in detail here. The side wall of the control console 3 is fixedly connected to the side wall of the support column 2. An operating table 18 is provided below the riveting device 4. The operating table 18 is made of thick steel plate and its side wall is fixedly connected to the side wall of the support column 2. Fixed columns 21 are fixedly connected to the four corners of the bottom of the operating table 18. The bottom of the fixed columns 21 is fixedly connected to the top of the base plate 1 to support the operating table 18 and keep it horizontal.

[0036] Specifically, when using the riveting device for manufacturing the motor fan cover, the operator first places the motor fan cover between the clamping plates 13, aligning the center of the fan cover with the axis of the rotating disk 7. Then, the operator inputs a start command through the control console 3, causing the motor-driven lead screw of the electric push rod 16 to rotate. The output end, with the electric push rod 16 body as the support point, moves forward in a straight line, driving the rotating disk 7 to rotate clockwise. The rotation of the rotating disk 7 causes the slide groove 14 on the side wall to move in a circular motion. The inclination angle of the slide groove 14 causes the internal guide post 12 to generate a radial component force in the slide groove 14 and the slide groove 10 of the fixed disk 8. Guided by the slide groove 14, the guide post 12 moves in a circular motion with the rotating disk 7 on one hand, and slides in a straight line along the axis of the slide groove 10 on the other hand. The radial sliding of the guide post 12 drives the slider 11 to move. Under the constraint of the guide groove 9, the slider 11 can only move radially towards the center of the fixed disk 8. Moving in a straight line, the slider 11 moves, causing the clamping plate 13 to slide synchronously towards the center. The anti-slip texture on the inner side of the clamping plate 13 comes into contact with the outer wall of the motor fan cover, generating friction. As the clamping plate 13 continues to move, the friction gradually increases until the outer wall of the motor fan cover is firmly clamped. At this point, the electric push rod 16 reaches the preset stroke and automatically stops moving. Subsequently, the drive motors on the side walls of the fixed plate 5 and the base 6 start, driving the rotating disk 7 and the fixed disk 8 to rotate as a whole. The motor fan cover moves in a circle with the rotating disk 7. Under the instruction of the PLC control system, the riveter 4 performs riveting operations on multiple riveting positions on the outer wall of the motor fan cover in sequence according to the preset trajectory and sequence. After each position is riveted, the rotating disk 7 rotates at a specified angle until all riveting points are processed. This achieves adaptive clamping of the clamping plate 13 for motor fan covers of different diameters without the need to change the clamps, improving the versatility of the equipment and production efficiency.

[0037] Reference Figure 4 and Figure 5The inner wall of the operating table 18 is slidably connected to a chip collection tray 22, which is made of stainless steel with a stainless steel mesh bottom, possessing corrosion resistance and easy-to-clean properties. It is used to collect metal chips generated during riveting operations. A fixed box 19 is fixedly connected to the bottom of the operating table 18. Multiple fans 20 are bolted to the inner wall of the fixed box 19. The fans 20 are axial flow fans, arranged in an array to generate negative pressure to suck up metal chips. The fans 20 are existing technology and will not be described in detail here. A movable plate 23 is slidably connected inside the chip collection tray 22. The movable plate 23 is made of engineering plastic, and its bottom is equipped with symmetrical return springs 27 made of spring steel. One end of each return spring 27 is fixedly connected to... Inside the chip collection drawer 22, the other end of the return spring 27 is fixedly connected to the outer wall of the movable plate 23 to provide the return force of the movable plate 23. Locking rods 24 are provided on both the left and right sides of the movable plate 23. The locking rods 24 are made of stainless steel. The outer walls of the locking rods 24 are fixedly connected to the limit blocks 25 by welding. The outer walls of the locking rods 24 and the limit blocks 25 are slidably connected in the guide holes inside the chip collection drawer 22 to lock the chip collection drawer 22 to the operating table 18. Limiting springs 26 are sleeved on the outer walls of the locking rods 24. The limiting springs 26 are made of spring steel. One end of the limiting springs 26 is fixedly connected to the inside of the chip collection drawer 22, and the other end of the limiting springs 26 is fixedly connected to the side wall of the limit blocks 25 to provide the return force for the locking rods 24 when unlocking.

[0038] Specifically, during the riveting operation, metal debris generated by the collision between the motor fan shroud and the rivet falls onto the surface of the workbench 18. At this time, multiple fans 20 inside the fixing box 19 rotate at high speed, generating a downward airflow that creates negative pressure on the surface of the workbench 18. Under the action of the airflow, the metal debris enters the chip collection tray 22 from the surface of the workbench 18, thus collecting the debris. When the riveting operation is completed and the worker needs to clean the chip collection tray 22, firstly, the worker presses the movable plate 23 inward by hand. The displacement of the movable plate 23 causes the return spring 27 at its bottom to be compressed. At the same time, the inward movement of the movable plate 23 causes the locking rods 24 on both sides to lose lateral pressure. At this time, the limit spring 26 returns to its original position, pushing the limit block 25 and the locking rod 24 inward, causing one end of the locking rod 24 to disengage from the lock inside the workbench 18. The fixed end is inserted into the recess on the side wall of the movable plate 23 to unlock the chip collection tray 22. Then, the operator can pull the chip collection tray 22 outward to remove it from the inside of the operating table 18, empty and clean the metal chips inside. After cleaning, align the chip collection tray 22 with the guide rail of the operating table 18 and push it inward to its original position. Then, release the hand that pressed the movable plate 23, and the return spring 27 releases the stored elastic potential energy, pushing the movable plate 23 to reset outward. During the reset process, the outer wall of the movable plate 23 squeezes the locking rod 24, causing the locking rod 24 to move outward. One end is inserted into the locking hole inside the operating table 18, and the other end is disengaged from the recess of the movable plate 23, thus restoring the mechanical locking between the chip collection tray 22 and the operating table 18. This achieves rapid cleaning of metal chips and avoids chip accumulation that affects riveting accuracy and equipment operation.

[0039] Working principle: When using the riveting device for manufacturing motor fan covers, the operator first places the motor fan cover between the clamping plates 13. Then, the electric push rod 16 is started through the control console 3. The output end of the electric push rod 16 pushes the connecting block 15 to move, thereby driving the rotating disk 7 to rotate. The rotation of the rotating disk 7 causes the slide groove 14 to rotate as well, which in turn causes the multiple guide posts 12 inside the slide groove 14 to move as well. The displacement of the guide posts 12 causes multiple sliders 11 to slide inside the guide groove 9. The displacement of the sliders 11 then causes the clamping plates 13 to slide inward to clamp and fix the outer wall of the motor fan cover. Subsequently, the motors on the side walls of the fixing plate 5 and the base 6 drive the entire motor fan cover to rotate. The riveter 4 performs riveting operations on multiple positions on the outer wall of the motor fan cover in sequence, thereby achieving the effect of quickly fixing motor fan covers of different sizes.

[0040] During the riveting process, metal shavings accumulate on the surface of the workbench 18. At this time, multiple fans 20 inside the fixed box 19 at the bottom of the workbench 18 start to rotate, sucking the metal shavings into the shavings collection drawer 22. After the riveting operation is completed, the worker presses the movable plate 23 inward. The inward displacement of the movable plate 23 compresses the return spring 27 and causes the locking rod 24, which was originally inserted into the workbench 18, to lose its lateral compressive force. Consequently, under the push of the limiting spring 26 on its outer wall, one end... The chip collection tray 22 is unlocked by disengaging from the operating table 18 and inserting the other end into the recessed side wall of the movable plate 23. This allows the operator to remove the chip collection tray 22 and clean it. The chip collection tray 22 is then inserted into the movable plate 23, the movable plate 23 is released, and the return spring 27 pushes the movable plate 23 back to its original position. The outer wall of the movable plate 23 then presses against the locking rod 24, causing one end to insert into the operating table 18. This completes the fixing of the chip collection tray 22, thereby achieving the effect of quickly cleaning metal chips and preventing chips from affecting the riveting accuracy.
