[0001] The utility model belongs to the technical field of automobile safety belt retractor production equipment, and particularly relates to a riveting equipment for a safety belt retractor connecting plate. BACKGROUND

[0002] The connecting plate is a connecting block between the safety belt retractor and the automobile frame, is responsible for fixing the retractor, transmitting load, adjusting the installation angle, and enhancing the structural strength. In the prior art, the connecting plate is riveted on the retractor through a riveting equipment.

[0003] The use steps of the riveting equipment of the prior art are as follows: an operator installs the retractor and the connecting plate, and a rivet in a tool of the equipment, a detection camera on the equipment detects whether the retractor and the connecting plate are installed in place through photographing, after the detection camera confirms that the retractor and the connecting plate are installed in place, the riveting equipment rivets the retractor and the connecting plate together, the operator takes down the riveted product, and uses a caliper to detect the height of the rivet after riveting.

[0004] The equipment and the riveting method of the prior art have the following defects:

[0005] 1. When the retractor, the connecting plate, and the rivet are installed in the tool of the riveting equipment together, because there is a gap between the two, the subsequent riveting process is more likely to produce defective products.

[0006] 2. Because there are many specifications of the connecting plate, if the position of the connecting plate is not fixed during detection, the detection camera is likely to make a false detection, so that subsequent processing produces defective products.

[0007] 3. In order to ensure the consistency of the production rhythm of each process, the operator generally only detects the first and last pieces produced by the riveting equipment using the caliper; firstly, the full-coverage detection of the size of the parts cannot be realized, and secondly, once the last piece is detected to be unqualified, the previous parts need to be rechecked, which is likely to cause the unqualified parts and rework.

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0032] Please see Figures 1 to 4 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0033] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0034] Please see Figure 1 This utility model provides a riveting device for a seat belt retractor connecting plate. Like existing riveting devices, this riveting device also includes:

[0035] like Figure 1 and Figure 2 The retractor fixture 1 shown is used to hold the retractor A.

[0036] like Figure 1 and Figure 2 The connecting plate fixture 2 shown is used to hold the connecting plate B.

[0037] like Figure 2 The detection camera 3 shown is used to detect the placement positions of the retractor A and the connecting plate B;

[0038] like Figure 1The riveting module 4 shown is used to rivet the placed retractor A and the connecting plate B together. After the detection camera 3 detects that the positions of the retractor A and the connecting plate B are correct, the riveting module 4 starts to work.

[0039] This riveting equipment differs from existing riveting equipment in that it also includes:

[0040] like Figure 1 and Figure 2 The flattening module 5 shown is used to press the placed retractor A and the connecting plate B together to eliminate the gap between their mating surfaces. This solves the problem in the prior art where, when the retractor A and the connecting plate B are installed together in the fixture of the riveting equipment, gaps easily exist between their mating surfaces, making it easier for defective products to occur during subsequent rivet installation and riveting processes.

[0041] like Figure 2 The displacement sensor 6 shown is used to detect the height of the rivet after the retractor A and the connecting plate B are riveted together. This displacement sensor 6 can inspect each workpiece, thus solving the problem in the prior art where, to ensure consistency in production cycles across processes, operators typically only use calipers to inspect the first and last pieces produced by the riveting equipment. This approach fails to achieve full coverage of part dimensions, and if the last piece fails inspection, the preceding parts need to be re-inspected, easily leading to batch defects and rework. The displacement sensor 6 can be adjusted in height as needed; the specific height adjustment method is not detailed here.

[0042] like Figure 1 and Figure 2 As shown, the connecting plate fixture 2 of this riveting equipment can adjust the position of the connecting plate B in both the horizontal and vertical directions, thereby solving the problem in the prior art where the inspection camera 3 is prone to false detection due to the large number of specifications of the connecting plate B, which would also lead to the production of defective products in subsequent processing.

[0043] In general, the working process of this riveting equipment is as follows: the operator places the retractor A and the connecting plate B on their respective fixtures. The connecting plate fixture 2 adjusts the position of the connecting plate B according to its specifications. The clamping module clamps the gap between the connecting plate B and the retractor A. The detection camera 3 checks whether the position of the clamped retractor A and the connecting plate B is correct. After the detection camera 3 confirms that there is no error, the riveting module 4 rivets the retractor A and the connecting plate B together. Finally, the displacement sensor 6 detects the height of the rivet to determine whether the riveting quality of this equipment is qualified. This improves the riveting quality between the retractor A and the connecting plate B, reduces the scrap rate, and reduces the labor intensity of the operator.

[0044] In another implementation, please refer to Figure 4The flattening module 5 includes a flattening telescopic cylinder 51, a flattening rod 52, and a fulcrum 53. The tail end of the flattening rod 52 is hinged to the telescopic end of the flattening telescopic cylinder 51. The fulcrum 53 is fixedly installed, and the middle part of the flattening rod 52 is hinged to the fulcrum 53. A flattening block 54 is fixedly connected to the head end of the flattening rod 52. The flattening block 54 can be designed in the shape of a palm to imitate the operation of a worker flattening the connecting plate B in the prior art. This embodiment provides a specific structural form of the flattening module 5. This structural form is simple, reliable in operation, and easy to maintain.

[0045] In another implementation, please refer to Figure 4 The connecting plate fixture 2 includes a base 21, a lifting rod 22, a lifting tightening knob 23, a horizontal moving rod 24, and a horizontal moving tightening knob 25. The base 21 is fixedly installed and has a lifting groove 26. The lifting rod 22 is slidably installed in the lifting groove 26. When the lifting tightening knob 23 is tightened, the lifting rod 22 is fixed in the lifting groove 26. The horizontal moving rod 24 has a horizontal moving groove 27 in the middle. The horizontal moving tightening knob 25 is rotatably installed on the top of the lifting rod 22. The horizontal moving groove 27 is fitted onto the horizontal moving tightening knob 25. When the horizontal moving tightening knob 25 is tightened, the horizontal moving rod 24 is fixed to the top of the lifting rod 22. In this embodiment, the connecting plate fixture 2 achieves the function of adjusting the position of the connecting plate B in both the horizontal and vertical directions using only two long rods with grooves in the middle, two knobs, and a base 21. The number of parts is small, the production cost is low, and it is easy to operate manually.

[0046] In another implementation, please refer to Figure 3 The riveting equipment also includes a transfer module 7, on which the retractor fixture 1 and the connecting plate fixture 2 are fixedly mounted. The transfer module 7 transfers the placed retractor A and the connecting plate B to the detection position of the detection camera 3, the riveting position of the riveting module 4, and the detection position of the displacement sensor 6. This avoids interference between different components and modules, and more importantly, ensures the safety of production. The specific structure of the transfer module 7 will be described below.

[0047] In another implementation, please refer to Figure 3The transfer module 7 includes a transfer power unit 74, a transfer slide rail 71, a transfer slider 72, and a support plate 73. The transfer slide rail 71 is fixedly installed on the riveting equipment via a transfer base 21, and the support plate 73 is slidably connected to the transfer slide rail 71 via the transfer slider 72. The transfer power unit 74 drives the support plate 73 to slide. The retractor fixture 1 and the connecting plate fixture 2 are both fixedly installed on the support plate 73. The flattening module 5 is fixedly connected to the support plate 73. The initial positions of the retractor fixture 1 and the connecting plate fixture 2 are located at the front end of the equipment. The riveting position of the riveting module 4 is located at the rear end of the equipment. When the operator uses the riveting equipment, the retractor A and the connecting plate B are placed in the two fixtures located at the front end of the riveting equipment, while the riveting module 4, which rivets the retractor A and the connecting plate B together, is located at the rear end of the riveting equipment, thereby avoiding personal injury to the operator from the riveting equipment and improving the safety of the riveting equipment.

[0048] In other implementations, such as Figure 1 and Figure 2 As shown, generally speaking, a retractor A will have multiple connecting plates B. Depending on the number of connecting plates B installed, multiple riveting devices can be set up. The parameters of different riveting devices can be adjusted to adapt to the installation of different connecting plates B, which will not be elaborated here.

[0049] In summary, this utility model improves the riveting quality between the retractor A and the connecting plate B by eliminating the gap between the mating surfaces of the retractor A and the connecting plate B through the flattening module 5, allowing the connecting plate fixture 2 to adjust the position of the connecting plate B in both horizontal and vertical directions, and using the displacement sensor 6 to detect the height of the rivets after riveting. This reduces the scrap rate and the labor intensity of the operator. It also addresses the following issues in the prior art: when the retractor A and the connecting plate B are installed together on the riveting equipment, gaps easily exist between their mating surfaces, making subsequent rivet installation and riveting processes more prone to defects; because the connecting plate B has many specifications, the inspection camera 3 is prone to false detections, which also leads to subsequent defective products; and to ensure the consistency of production rhythm in each process, operators generally only use calipers to inspect the first and last parts produced by the riveting equipment, which cannot achieve full coverage inspection of part dimensions, and if the last part fails inspection, the preceding parts need to be re-inspected, easily causing batch defects and rework. Therefore, this utility model effectively overcomes the shortcomings of the prior art and has high industrial application value.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
