Description

Technical Field

[0001] This utility model belongs to the field of bushing pressing technology, specifically relating to an angle adjuster bushing pressing device. Background Technology

[0002] An adjuster is a device installed on a car seat to adjust the seat back angle. With the continuous advancement of industrial production, the types and structures of car seat adjusters, as a core component of car seats, are becoming increasingly diverse. Correspondingly, the adjuster bushing, located in the core part of the adjuster, bears and transmits torque loads, ensuring the strength and rigidity of the seat / back connection and increasing occupant protection in the event of a collision; therefore, its types are also increasing. Due to its large diameter, thin wall, and small height, the adjuster bushing is easily deformed during the pressing process of the adjuster and bushing using existing automated pressing equipment, which can easily lead to a low yield rate of the final product. How to better maintain the shape of the bushing during the pressing process, thereby reducing deviations and ensuring pressing quality, has become a technical problem that needs to be solved. Utility Model Content

[0021] This utility model proposes a bushing pressing device for an angle adjuster. To make the purpose, technical solution, and advantages of this utility model clearer, the following description, in conjunction with the appendix, is provided. Figures 1-6 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0022] An angle adjuster bushing pressing device includes a bushing pressing mechanism, a bushing feeding mechanism, and an angle adjuster placing mechanism. An angle adjuster transferring mechanism is provided between the angle adjuster placing mechanism and the bushing pressing mechanism.

[0023] The bushing feeding mechanism is located on one side of the bushing pressing mechanism and includes a feeding conveyor belt 1 connected to the output end of an external bushing feeding mechanism. A bushing cutting mechanism is located on one side of the feeding conveyor belt 1. The bushing cutting mechanism includes a cutting cylinder 21, with a slide rail on one side. A connecting plate 22 is mounted on the slide rail, and one side of the connecting plate 22 is connected to a cutting plate 23. The cutting plate has a bushing cutting opening at its distal end. The movement direction of the cutting plate 23 is perpendicular to the horizontal movement direction of the feeding conveyor belt 1. When the cutting cylinder 21 operates, it drives the cutting plate 23 via the connecting plate 22 to push the bushing 24 towards the bushing pressing mechanism.

[0024] The bushing pressing mechanism includes a pressing frame 6. In this embodiment, the pressing frame is a C-shaped frame. A pressing table 26 is provided in the middle of the pressing frame 6, and a pressing port is opened on the pressing table 26. A lower pressing head 65 is provided on the pressing port. An upper pressing cylinder 61 is provided on the upper part of the pressing frame 6, and the upper pressing head 63 is connected to the upper pressing cylinder 61. A lower pressing cylinder 64 is provided on the lower part of the pressing frame 6, and the lower pressing cylinder 64 is arranged opposite to the upper pressing cylinder 61. A lower pressing rod is connected to the lower pressing cylinder 64. A frame cylinder 66 is provided on one side of the lower pressing cylinder 64. A hollow seat 661 protrudes upward on the frame. When the frame cylinder 66 is working, it will drive the frame upward, thereby driving the hollow seat 661 to move upward. The lower pressure rod is placed inside the hollow seat 661. The pressing cylinder 64 operates, driving the lower pressure rod to move up and down within the hollow seat 661. The cutting plate moves the bushing to the pressing table 26, and the cylinder on the pressing machine frame drives the corresponding pressing head and pressing rod to cooperate in pressing the bushing. A baffle plate 25 is provided at one end of the pressing table 26.

[0025] Specifically, the upper pressure head 63 is cylindrical in shape, with evenly distributed retaining edges 631 around its outer circumference. The bottom of each retaining edge 631 is a certain distance from the bottom of the upper pressure head 63, the distance being approximately equal to the height of the bushing. The lower pressure head 65 has an embedded groove 651 that mates with the upper pressure head 63 and the retaining edges. The gap between the lower and upper pressure heads corresponds to the position where the bushing is to be pressed into the angle adjuster.

[0026] The upper end face of the pressing head 65 has two upwardly protruding straight blocks 652 on both sides, with the distance between the two straight blocks 652 being approximately equal to the diameter of the bushing. When the pressing head 65 rises to its position, the baffle plate 25 will be positioned between the two straight blocks 652, thus stopping the far end of the bushing. The near end stop of the bushing is limited by the bushing cutting opening of the cutting plate.

[0027] The angle adjuster transfer mechanism includes a transfer drive 52 and a transfer plate 5 placed on the transfer drive 52. Both ends of the transfer plate 5 are provided with fixtures 51 for placing the angle adjuster. When the transfer drive 5 is working, it drives both ends of the transfer plate 5 to switch below the pressing operation table 26.

[0028] An angle adjuster loading mechanism is provided on the outside of the angle adjuster transfer mechanism. The angle adjuster loading mechanism includes a platform 4 and an angle adjuster loading fixture 41 placed on the platform 4. The angle adjuster 7 is placed on the angle adjuster loading fixture 41. An angle adjuster transfer mechanism (not shown in the figure) is also provided above the platform 4. The angle adjuster transfer mechanism is equipped with a transfer gripper for picking up the angle adjuster on the platform and transferring it to the angle adjuster transfer mechanism. At the same time, it can also transfer the angle adjuster that has completed bushing pressing on the angle adjuster transfer mechanism to the platform 4 to await final removal.

[0029] To better understand this utility model, the following describes the operation between the angle adjuster and the bushing pressing:

[0030] The angle adjuster to be pressed is picked up by the angle adjuster transfer mechanism and placed on the angle adjuster fixture on the material platform 4. The transfer drive operates, causing the transfer plate 5 to rotate horizontally 180°, rotating the angle adjuster to be pressed to the pressing position below the pressing operation table 26. The frame cylinder operates, causing the hollow seat to move upward. The top of the hollow seat will abut against the bottom end face of the adjuster and lift it up. Usually, the angle adjuster is removed from the transfer plate 5, meaning that the pressing force of the subsequent bushing will ultimately be borne by the frame. The pressing cylinder actuates, driving the pressing rod to extend upwards through the hollow seat into the angle adjuster. The bushing 24, after being output from the bushing feeding mechanism, enters the feeding conveyor belt 1 and is transported to the bushing cutting mechanism. The bushing cutting cylinder operates, pushing the bushing into the lower pressing head of the bushing pressing mechanism. The upper cylinder operates, driving the upper pressing head downwards. During the pressing process, the bushing is pressed through the gap between the upper and lower pressing heads into the angle adjuster via the retaining edge, completing the bushing installation within the angle adjuster. Because the bushing's circumference is confined between the upper and lower pressing heads, and there are limits around the circumference, the bushing will not deform during the pressing process, thus ensuring the quality of the pressing. After pressing is completed, each cylinder returns to its original position, ready for the next pressing cycle.
