Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Please see Figure 1-11 A riveting device for a magnesium alloy forged bracket for a vehicle seat includes a base 1 and a column 2 fixedly mounted thereon, a riveting head 3 slidably mounted on the column 2, and further includes:

[0035] The base plate 51 is fixedly installed on the base 1;

[0036] The first support plate 54 and the second support plate 55 are both rotatably mounted on the base plate 51;

[0037] The limiting block 56 is slidably mounted on the second support plate 55;

[0038] The slide rail 61 is fixedly installed on the base plate 51. The slide rail 61 is located between the first support plate 54 and the second support plate 55. The slide rail 61 has an inclined groove, and a support rod 71 is slidably installed on the inclined groove. The support rod 71 is used to support the first support plate 54 and the second support plate 55.

[0039] The sliding support rod 71 allows it to move within the inclined groove. As it moves, it provides angular support to the first support plate 54 and the second support plate 55 in the same row, ensuring that they remain at the same inclination angle of 11 degrees. (Reference) Figure 4 The first support plate 54 and the second support plate 55 in the first row on the left are set at an inclination angle of 11 degrees relative to the plane. At this time, the first support plate 54 and the second support plate 55 in the first row on the left will support and position one end of the first workpiece 8 and the second workpiece 9. At the same time, the first support plate 54 and the second support plate 55 in the second and third rows on the left can be adjusted to rotate to an inclination angle of 11 degrees. At this time, the first support plate 54 and the second support plate 55 in the second and third rows will limit the bottom surface of the second workpiece 9 below. At the same time, the first support plate 54 and the second support plate 55 in the fourth, fifth and rear rows on the left will rotate to an inclination angle of 11 degrees. At this time, these first support plates 54 and the second support plate 55 will support and limit the first workpiece 8 above. The first support plate 54 and the second support plate 55 at an inclination angle of 11 degrees will keep the right ends of the first workpiece 8 and the second workpiece 9 aligned, thereby ensuring that the rivet holes on the first workpiece 8 and the second workpiece 9 are aligned.

[0040] The limiting block 56 is slidably installed on the second support plate 55. When the first support plate 54 and the second support plate 55, located at an inclination angle of 11 degrees, support the second workpiece 9 below, the minimum height of the second workpiece 9 can be determined. At the same time, the first support plate 54 and the second support plate 55, located at an inclination angle of 11 degrees, will determine the position of one end of the second workpiece 9. Meanwhile, the position of the limiting block 56 on the second support plate 55 can be slidably determined so as to determine the position of the other side end of the second workpiece 9. At this time, the position of the second workpiece 9 can be accurately determined simply by placing the second workpiece 9 on the first support plate 54 and the second support plate 55.

[0041] When the first support plate 54 and the second support plate 55 are under pressure, the pressure will be distributed to the support rod 71. At this time, the support rod 71 is set in the inclined groove and can contact the bottom wall of the inclined groove to bear part of the pressure.

[0042] The limiting block 56 is equipped with screws, so that the limiting block 56 can be fixed by the screws when it moves on the second support plate 55.

[0043] In another embodiment of the present invention: the base plate 51 is inclined toward the bottom end of the inclination angle 11;

[0044] When the base plate 51 is set, it is tilted downwards towards one end of the tilt angle 11. So when the first support plate 54 and the second support plate 55 are set at the tilt angles a, b, and c, respectively, and the limiting block 56 is engaged, when the base plate 51 is tilted downwards towards the tilt angle 11, the first workpiece 8 and the second workpiece 9 will slide towards the tilt angle 11 when placed on the first support plate 54 and the second support plate 55. At this time, the three end faces of the first workpiece 8 and the second workpiece 9 will be positioned by the first support plate 54, the second support plate 55 and the limiting block 56, so that the first workpiece 8 and the second workpiece 9 can be automatically slid and aligned after being placed directly.

[0045] In another embodiment of the present invention: the top ends of the first support plate 54 and the second support plate 55 are both triangular in shape;

[0046] Among them, reference Figure 5-7 When the rightmost end of the workpiece is positioned by the first support plate 54 and the second support plate 55 in the first row, the angle of the hypotenuse of the top triangle can be changed by rotating the angle of the first support plate 54 and the second support plate 55, so that the first workpiece 8 and the second workpiece 9 are staggered on the plane, thereby ensuring that the rivet holes on the first workpiece 8 and the second workpiece 9 are aligned.

[0047] like Figure 5 When the hypotenuse of the triangle at the top of the first support plate 54 and the second support plate 55 is rotated to a vertical position, the first workpiece 8 and the second workpiece 9 can remain vertical and flush when they come into contact with the hypotenuse of the triangle.

[0048] For example Figure 6 As the first support plate 54 and the second support plate 55 continue to rotate to the left, the hypotenuse of the triangular shape at the top of the first support plate 54 and the second support plate 55 tilts to the left. At this time, the upper first workpiece 8 will abut against the first support plate 54 first, while the lower second workpiece 9 will abut against the first support plate 54 later, thus creating a vertical misalignment between the first workpiece 8 and the second workpiece 9, with the upper first workpiece 8 slightly to the left. Figure 7 This allows the first workpiece 8 to be positioned further to the right when the first workpiece 8 and the second workpiece 9 are misaligned, thereby ensuring that the rivet holes on the first workpiece 8 and the second workpiece 9 are aligned.

[0049] In another embodiment of the present invention: a connecting strip 72 is fixedly installed between two support rods 71 ​​in the same group, and the connecting strip 72 is concave in shape, and a screw is threaded through the support rod 71;

[0050] Two support rods 71 ​​in the same group are connected by a concave connecting strip 72, which passes through the bottom of the slide rail 61. Therefore, when one of the straight rods is slid, the support rod 71 on the other side of the slide rail 61 can also be moved, thereby ensuring that the support rods 71 ​​on both sides of the slide rail 61 are kept at the same height, thus ensuring that the first support plate 54 and the second support plate 55 in the same row have the same tilt angle of 11 degrees.

[0051] The screw passes through the straight rod and fits against the slide rail 61, thus restricting the movement of the support rod 71 when the screw is tightened.

[0052] In another embodiment of the present invention: a slider 3.1 is fixedly installed on the riveting head 3, and a lead screw 4 is rotatably installed on the column 2, and the lead screw 4 is threadedly connected to the slider 3.1. A servo motor is provided inside the base 1, and the output end of the servo motor is fixedly connected to the lead screw 4. The servo motor can drive the lead screw 4 to rotate.

[0053] The bottom end of the riveting machine is fixedly installed with an abutment plate 68;

[0054] A slide frame 65 is slidably mounted on the slide rail 61, a support 66 is mounted on the slide frame 65, and a rivet is provided on the support 66.

[0055] A connecting seat 62 is fixedly installed on the base plate 51. A rotating plate 63 is rotatably installed on the connecting seat 62. The rotating plate 63 is located below the abutment plate 68, and a round rod 64.1 is fixedly installed at the end of the rotating plate 63 away from the abutment plate 68. The round rod 64.1 penetrates into the interior of the slide frame 65.

[0056] The sliding frame 65 is concave, and the round rod 64.1 passes through the concave shape. The sliding frame 65 is vertically slidably installed in the slide rail 61. When the riveting head 3 drives the abutment plate 68 to descend, the abutment plate 68 will contact the larger end of the rotating plate 63. At this time, the other end of the rotating plate 63 will drive the round rod 64.1 to rotate upward. At this time, the round rod 64.1 will drive the sliding frame 65 to rise, and the sliding frame 65 will drive the support 66 to rise.

[0057] The slide rail 61 has a groove 61.1, and the size of the groove 61.1 is adapted to the size of the rivet. Several rivets can be set through the groove 61.1. At the same time, the slide rail 61 can be connected to a vibrating screen or a feeder to feed the rivets until the rivets are located on the support 66. Since the support 66 is L-shaped, when the slide frame 65 rises, the support 66 will drive the rivets to rise and be inserted into the riveting holes of the first workpiece 8 and the second workpiece 9. At the same time, the riveting head 3 descends to rivet the top of the rivet until the riveting is completed. Then, the riveting head 3 rises and drives the abutment plate 68 to rise and move the support 66 back to reset so that the next rivet can rise.

[0058] In another embodiment of the present invention: a baffle 67 is fixedly installed on the support 66;

[0059] Since the base plate 51 is inclined downwards at an angle of 11, the rivets on the slide rail 61 will move toward the support 66 until they slide onto the support 66. When the support 66 rises, the rivets are prone to sliding below the support 66 and getting stuck. Therefore, by setting a baffle 67, when the support 66 rises, the baffle 67 also rises, thereby restricting the movement of other rivets.

[0060] In another embodiment of the present invention: a bottom groove 61.2 is provided on the slide rail 61;

[0061] The bottom groove 61.2 can be used to install a rotating plate 63 and a side plate 64, which facilitates their rotation.

[0062] In another embodiment of the present invention: a rotating rod 661 is rotatably mounted on the support 66, the rotating rod 661 is threaded through the slide frame 65, and a limiting strip 662 is fixedly mounted on the support 66, the limiting strip 662 slides through the slide frame 65;

[0063] The horizontal position of the support 66 can be finely adjusted by rotating the rotating rod 661, making it easier to align with the riveting hole, while the horizontal movement of the support 66 can be restricted by the limiting strip 662.

[0064] In another embodiment of the present invention: a spring 69 is fixedly installed between the bottom end of the rotating plate 63 and the bottom plate 51;

[0065] When the riveting head 3 moves the abutment plate 68 downward to push the rotating plate 63 to rotate, the spring 69 will be compressed. In the initial stage, the abutment plate 68 will push the rotating plate 63 to rotate, thereby causing the rivet to rise. After the rivet rises to the designated position, the abutment plate 68 will move downward from one side of the rotating plate 63. Figure 11 As shown, at this time, the downward movement of the abutment plate 68 will no longer drive the rotating plate 63 to rotate. The angle of the rotating plate 63 will be fixed, while the riveting head 3 can still descend to perform riveting operation on the rivet. After the riveting is completed, as the riveting head 3 rises, the abutment plate 68 will also rise until the abutment plate 68 is removed from one side of the rotating plate 63. Then, the spring 69 will push the rotating plate 63 to rotate and reset.

[0066] In another embodiment of the present invention: a connecting frame 52 is fixedly installed on the base plate 51, and a rotating shaft 53 is fixedly installed on both the first support plate 54 and the second support plate 55. The rotating shaft 53 is rotatably installed inside the connecting frame 52.

[0067] The first support plate 54 and the second support plate 55 are respectively installed in different connecting frames 52 via a rotating shaft 53.

[0068] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
