Description

Technical Field

[0001] This utility model relates to the field of riveting mechanism technology, specifically a riveting mechanism for windshield wiper manufacturing. Background Technology

[0002] In the manufacturing process of windshield wipers, the riveting process is a key step in connecting various components of the wiper (such as the wiper arm and wiper blade connector, the motor output shaft and transmission components, etc.). The quality of the connection directly affects the service life and working stability of the wiper.

[0003] A search revealed a patent, CN219425578U, which discloses a wiper arm riveting and positioning mechanism. The mechanism includes a base plate with a rotation control component on its top surface. A rotating platform is positioned above the rotation control component, and a positioning seat is fixedly connected to the top surface of the rotating platform. The positioning seat has a first positioning component and a second positioning component for limiting the position of the wiper arm. A fixing frame is fixedly connected to the left side of the top surface of the base plate, and a riveting machine body is mounted on the surface of the fixing frame. The rotation control component includes a control motor, which is fixedly mounted on the top surface of the base plate. A motor shaft is fixedly connected to the output end of the control motor. This mechanism facilitates continuous riveting of wiper arms without requiring machine downtime for loading and unloading, effectively shortening the processing interval. It also allows for rapid positioning of the wiper arm during processing, further improving processing efficiency.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings: The aforementioned comparative document describes a method where several positioning seats are set on a rotating platform. Two wiper components to be riveted are secured within these seats, and the platform is rotated to a position below the riveting machine body. The riveting machine body then rivets the two wiper components together. However, in reality, some wiper components require riveting on both sides, such as when connecting the wiper head to the wiper arm. When using the riveting mechanism described in the comparative document, the riveted components need to be flipped over and riveted again, reducing the efficiency of riveting wiper components. Therefore, there is an urgent need in the art to improve the riveting mechanism used in wiper production to overcome the shortcomings of the prior art. Utility Model Content

A second drive motor 6 for driving the rotating disk 2 is fixedly installed inside the support frame 1. Two symmetrical support seats 7 are provided on one side of the rotating seat 4. Two clamping units for holding are provided on one side of each support seat 7. A third drive motor 8 for driving the two clamping units to move synchronously towards or away from each other is fixedly installed on the upper part of each support seat 7. A connecting frame 9 adapted to the rotating disk 2 is fixedly installed on one side of the support frame 1. The riveting machine body 10 is fixedly installed on the inner top wall of the connecting frame 9 and adapted to the position of the clamping units. A lifting mechanism is fixedly installed on the side of the connecting frame 9. The main controller 11, which achieves the programming control effect, includes a clamping unit comprising two movable plates 12 located on one side of the support base 7. Each of the two movable plates 12 has a positioning frame 13 on its opposite side. A first sliding block 14 is fixedly installed at one end of each movable plate 12. A first sliding groove 16 adapted to the first sliding block 14 is opened on one side of the support base 7. A first drive screw 15, one end of which is fixedly installed to the output end of the third drive motor 8, is rotatably connected in the first sliding groove 16. The first drive screw 15 passes through the first sliding block 14 and is threadedly connected to it. A first threaded post 17 passing through the movable plate 12 is fixedly installed on one side of the positioning frame 13. A first limit nut 18 for limiting and fixing is threadedly connected to the side of the first threaded post 17. A telescopic device 19 with telescopic effect is fixedly installed at the bottom of the connecting frame 9. A support 20 adapted to the riveting machine body 10 is fixedly installed at the upper end of the telescopic device 19.

[0022] The specific implementation method in this embodiment is as follows: The riveting machine body 10 described above is a known prior art technology, which can rivet two parts together with rivets. When it is necessary to rivet two parts of a windshield wiper, the ends of the two parts are connected, and the rivets are inserted between the ends of the two parts. The two parts are placed on the positioning brackets 13 on the two moving plates 12 respectively, and the positions to be riveted are aligned and positioned. The two third drive motors 8 are turned on, and the output of the third drive motors 8 drives the first drive screw 15 to rotate. The threads on the inner side of the first sliding groove 16 are symmetrical and opposite. When the first drive screw 15 rotates, it drives the two first sliding blocks 14 to move towards each other simultaneously within the first sliding groove 16. The first sliding blocks 14 drive the moving plate 12 to move, clamping and fixing the two parts. Then, the second drive motor 6 is turned on to rotate the wiper parts that have been positioned and clamped to directly below the riveting machine body 10. The telescopic device 19 is then activated. The telescopic device 19 is an electric telescopic rod or a hydraulic telescopic rod. The telescopic end of the telescopic device 19 drives the support 20 to move upward, and the support 20 abuts against... Connecting to the lower part of the component riveting position, the riveting machine body 10 is turned on. The lower end of the riveting machine body 10 moves down and rotates to rivet the two wiper components. After the upper part is riveted, the riveting machine body 10 moves the riveting head upward, the telescopic device 19 moves downward, and the first drive motor 5 is turned on. The output end of the first drive motor 5 drives the rotating seat 4 to rotate within the through-hole 3, flipping the component. Then, the telescopic device 19 again drives the support 20 to move upward, and the riveting machine body 10 moves downward to rivet the lower part of the two components, achieving... The multi-station riveting mechanism connects wiper components by rotating the first drive motor 5 to flip the riveted components on one side, enabling simultaneous riveting of two opposite sides of the wiper components, thus improving the efficiency of riveting wipers. The positioning frame 13 can rotate, and its angle can be adjusted, making it suitable for riveting two components at different angles. The first limiting nut 18 on the side of the first threaded post 17 is locked and fixed to limit the angle of the positioning frame 13, thus expanding the applicability of the riveting mechanism.

[0023] Example 2 Please see Figure 3 , Figure 4 and Figure 6 This embodiment includes the above embodiment, and further includes: a number of positioning frames 13, a second sliding block 21 fixedly installed at the lower end of the telescopic device 19 and the upper end of the riveting machine body 10, a second sliding groove 22 adapted to the second sliding block 21 being opened on the upper and lower side walls of the connecting frame 9, a second driving screw 23 being rotatably connected in the second sliding groove 22, and two fourth drive motors 24 fixedly installed on one side of the connecting frame 9, which synchronously drive the two second drive screws 23 to rotate respectively.

[0024] In this embodiment, the positioning brackets 13 are of several sizes. These positioning brackets 13 can be of the same size, enabling the riveting of several wiper components at once. Alternatively, the positioning brackets 13 can be of different sizes, using a matching size positioning bracket 13 to clamp and fix components of different sizes, thus improving the applicability of the riveting structure. When riveting several groups of wiper components, the components are aligned with their riveting positions and clamped and fixed. During riveting, the fourth drive motor 24 is activated. Two fourth drive motors 24 are... The output of the stepper motor and the fourth drive motor 24 drives the second drive screw 23 to rotate. The rotation of the second drive screw 23 drives the second sliding block 21 to slide in the second sliding groove 22. The two second sliding blocks 21 respectively drive the telescopic device 19 and the riveting machine body 10 to move, thereby adjusting the position of the riveting machine body 10 and the support 20. The riveting points of several sets of wiper parts are in a straight line and are adapted to the moving direction of the telescopic device 19 and the riveting machine body 10, so as to achieve the effect of riveting several sets of wiper parts at the same time, and further improve the efficiency of the riveting mechanism.

[0025] Example 3 Please see Figure 3 and Figure 5 This embodiment includes all the above embodiments, and further includes: a movable seat 28 is fixedly installed on one side of the bearing seat 7, a movable groove 29 adapted to the movable seat 28 is opened on one side of the rotating seat 4, a second threaded post 25 extending to the outside is fixedly installed on the upper part of the movable seat 28, an adjustment groove 26 adapted to the second threaded post 25 is opened on the upper part of the rotating seat 4, and a second limit nut 27 is threadedly connected to the side of the second threaded post 25.

[0026] In this embodiment, when different parts need to be riveted, the positions of the two bearing seats 7 can be adjusted to ensure the stability of the parts when clamping them. When the bearing seat 7 moves, the moving seat 28 slides in the moving groove 29, and the second threaded column 25 slides in the adjusting groove 26. After the position of the bearing seat 7 is adjusted to a suitable position, the second limit nut 27 is locked to limit and fix the position of the bearing seat 7.
