[0020] 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.

[0021] This utility model provides, for example Figure 1-4 The positioning fixture for seat tray riveting shown includes a fixed frame 1, a riveting assembly 2 on the top of the fixed frame 1, a worktable 3 on the table surface of the fixed frame 1, the worktable 3 being connected to the fixed frame 1 by bolts, a mounting plate 4 on the top of the worktable 3, a mounting groove 5 on the top of the worktable 3, a cross groove 6 on the surface of the mounting plate 4, and threads in both the mounting groove 5 and the cross groove 6. The mounting plate 4 and the worktable 3 are connected by bolts, a placement plate 7 is welded to the top of the mounting plate 4, a limiting plate 8 is welded to the top of the placement plate 7, and a limiting rod 9 is fixedly connected to the top of the placement plate 7. By using the limiting plate 8 and the limiting rod 9, the seat tray to be riveted is placed between the limiting plate 8 and the limiting rod 9, and the limiting plate 8 and the limiting rod 9 limit the seat tray, thereby quickly aligning the seat tray for riveting and facilitating the riveting process.

[0022] The riveting assembly 2 includes a locking plate 21 connected to the top of the fixing frame 1. The locking plate 21 is connected to the top of the fixing frame 1 by bolts. A cylinder 22 is fixedly connected to the top of the locking plate 21. An air pump is connected to the cylinder 22 through a pipe, and gas is delivered to the cylinder 22 so that the output end of the cylinder 22 extends, thereby pushing the riveting head 23 to move downward. The use of connecting the cylinder 22 to the air pump is prior art and is a common technique used by those skilled in the art, so it will not be described in detail. The output end of the cylinder 22 is fixedly connected to the riveting head 23. By using the cylinder 22 to push the riveting head 23, the riveting head 23 can be used to rivet the rivets on the seat tray.

[0023] The top of the placement plate 7 is provided with a slot 10, and the limiting plate 8 is located on one side of the slot 10. The slot 10 is designed to lock the side of the seat tray that is connected to the seat. Since the side of the seat tray needs to be connected to the seat, it is generally thin, so it can be locked into the slot 10. The slot 10 can also limit the position of the seat tray.

[0024] Two fixing blocks 11 are welded to the front side of the limiting plate 8. Each fixing block 11 has two grooves on opposite sides, and springs 12 are fixedly connected within these grooves. The springs 12 only position the seat tray; they do not clamp it, thus preventing the seat tray from wobbling. To maintain the stability of the seat tray, it can be manually supported on both sides. Since the travel distance of the cylinder 22 is fixed, it will not cause injury to the hands. Furthermore, the rivet head 23 rivets from top to bottom, and the springs 12 are located on both sides. The spring 12 will not transmit force to the spring 12. The other end of the spring 12 is fixedly connected to the compression rod 13, and the other end of the compression rod 13 is fixedly connected to the positioning clamp 14. By placing the seat tray between the two positioning clamps 14 and compressing the positioning clamps 14, the positioning clamps 14 compress the spring 12 through the compression rod 13, thereby compressing the spring 12. The springs 12 on both sides have the same elastic force. Through the restoring property of the spring 12, the seat tray is placed in the middle position, thereby better positioning the seat tray.

[0025] A triangular plate 15 is fixedly connected to the top of the positioning clamp 14. The hypotenuse of the triangular plate 15 is arc-shaped. When the seat tray is placed on the top of the triangular plate 15 and pressed down, the friction causes the triangular plate 15 to move to both sides, thereby pressing the seat tray between the two positioning clamps 14.

[0026] Working principle of this utility model:

[0027] By placing the seat tray between two positioning clamps 14 and pressing the positioning clamps 14, the positioning clamps 14 compress the spring 12 through the pressing rod 13, thereby compressing the spring 12. The springs 12 on both sides have the same elastic force. Through the restoring property of the spring 12, the seat tray is positioned in the middle position, and the left and right positions of the seat tray are positioned. The seat tray to be riveted is placed between the limiting plate 8 and the limiting rod 9. The limiting plate 8 and the limiting rod 9 limit the front and rear positions of the seat tray, so that the riveting position of the seat tray can be quickly aligned. By using the cylinder 22 to push the riveting head 23, the rivets on the seat tray can be riveted.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
