Description

Technical Field

[0001] This utility model relates to the technical field of hardware processing equipment, and more specifically, to a spring feeding device. Background Technology

[0002] A hinge is a common metal hinge structure used in furniture and other fields, as shown in the attached image. Figure 6 The schematic diagram of the hinge shown includes a hinge arm 34, with a cam 35 installed inside one end of the hinge arm 34. A hinge subarm 36 is then inserted and installed at the end of the hinge arm 34 near the cam 35. A spring support 37 is installed inside the hinge subarm 36, forming a spring cavity 38 between the spring support 37 and the hinge subarm 36. A spring 39 is placed inside the spring cavity 38. A pin 40 is then inserted to press the spring 39, causing the lower end of the spring 39 to press against the cam 35, thereby providing a damping effect during the swinging of the hinge subarm 36.

[0003] However, in the existing hinge assembly equipment structure, the hinge is usually placed on a fixture, which switches positions via a rotating worktable. When rotating to the spring installation process, the spring needs to be manually placed in the spring cavity 28. Then, the operator needs to use a tool to press the spring tightly before inserting the pin 40. During this process, because the spring 39 has a relatively large elastic force, the operator needs to exert a lot of force to press the spring 39 down. Then, during the process of inserting the pin 40, because the pin hole of the hinge arm 36 is relatively small, inserting the pin 40 is also quite troublesome, thus reducing the work efficiency of the spring installation process.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Combination Figures 1 to 6 The spring feeding device shown includes a fixture 1 for placing a hinge. The fixture 1 is mounted on a rotating work plate. A spring-releasing unit 2 is provided on one side of the rotating work plate, and a base 3 is provided on the other side of the spring-releasing unit 2. A spring-compressing unit 4 and a pin-guiding unit 5 are respectively mounted on the base 3. The spring-compressing unit 4 presses the spring 39 tightly into the hinge, and the pin-guiding unit 5 limits the spring 39 within the hinge. A pin-guiding unit 6 is provided on the side of the fixture 1 away from the base 3. The pin-guiding unit 6 presses a pin 40 against the pin-guiding unit 5, thus limiting the pin 40 and the spring 39 within the hinge. The beneficial effect is that the spring is automatically placed into the spring cavity 38 by the spring release unit 2, and then the spring 39 is pressed down by the spring compression unit 4. At the same time, the spring 39 is confined in the spring cavity 38 by the pin guide unit 5 to prevent the spring 39 from accidentally popping out. Then, the pin guide unit 6 presses the pin guide unit 5 with the pin 40, so that the pin guide unit 5 exits the hinge and the pin 40 enters the hinge, thereby completing the assembly of the spring 39. The whole process does not require manual operation, reducing labor intensity, saving time and effort, improving work efficiency, and preventing the spring 39 from falling out, making the assembly process more stable.

[0022] Specifically, the spring-releasing unit 2 in this embodiment includes a fixed rod 7, a vertical plate 8 installed on one side of the upper end of the fixed rod 7, a first slide plate 9 installed on the side of the vertical plate 8 via a first slide rail slider (41), a spring channel seat 10 installed on the side of the first slide plate 9, a spring inlet pipe 11 provided at the upper end of the spring channel seat 10, a first cylinder 12 installed at the upper end of the vertical plate 8, and the cylinder shaft of the first cylinder 12 connected to the first slide plate 9; when the fixture 1 rotates to below the spring channel seat 10, the spring channel seat 10 moves downward, so that the spring channel seat 10 corresponds to the spring cavity 38, and the spring 39 can be inserted from the spring inlet pipe 11, so that the spring 39 falls into the spring cavity 38, and then the fixture 1 rotates to the spring-compressing unit 4 via the rotating work plate. It is worth noting that the rotating work plate is a work plate structure driven by a motor, which is commonly used in hardware assembly production equipment, and is a technical structure that can be understood by those skilled in the art, and will not be described in detail here.

[0023] The compression spring unit 4 includes a connecting frame 13. A second slide plate 14 is mounted on the side of the connecting frame 13 facing the pin insertion unit 6 via a second slide rail slider (42). A second cylinder 16 mounted on the connecting frame 13 is connected to one side of the second slide plate 14. A compression hinge seat 15 is mounted on the second slide plate 14. A compression spring rod 18 is inserted into the compression hinge seat 15. The compression spring rod 18 can move up and down within the compression hinge seat 15. By pressing down the compression hinge seat 15, the hinge arm 36 on the hinge is pressed tightly to prevent the pin 23 and pin 40 from slightly shaking and failing during insertion. After the compression hinge seat 15 is pressed down, the compression spring rod 18 is pressed down to press down the spring 39 in the spring cavity 38.

[0024] It is worth noting that the upper end of the compression spring rod 18 is connected to the third cylinder 19 mounted on the upper end of the connecting frame 13. The cylinder shaft of the third cylinder 19 is connected to the compression spring rod 18 through the rod seat 17. Compression spring ends 20 are provided on both sides of the lower end of the compression spring rod 18. A pin groove 21 is provided between the two compression spring ends 20. The pin groove 21 can accommodate the pin 40 to pass through. This allows the compression spring ends 20 to press against both sides of the spring 39. After the spring 39 is compressed in the spring cavity 38, the pin groove 21 can facilitate the insertion of the guide pin 23 and the pin 40.

[0025] The pin-piercing unit 6 in this embodiment includes a pin holder 22 mounted on a connecting frame 13. The pin holder 22 is located below the second slide plate 14. A guide pin 23 is inserted into the pin holder 22. A fourth cylinder 24 mounted on a base 3 is provided on the side of the connecting frame 13 away from the pin holder 22. The cylinder shaft of the fourth cylinder 24 is connected to the guide pin 23. The guide pin 23 is driven by the fourth cylinder 24 to penetrate into the hinge arm 36. Since the spring 39 is compressed in the spring cavity 38, the guide pin 23 can pass through the pin groove 21, further stabilizing the spring 39 in the spring cavity 38.

[0026] The pin-through unit 6 includes a pin channel connector 25. The upper end of the pin channel connector 25 is mounted on a third slider 26 via a third slide rail slider (43). A pin channel seat 27 is mounted on the third slider 26. A pin channel is provided inside the pin channel seat 27. One end of the pin channel seat 27 is connected to a pin inlet pipe 28. A movable ejector pin 30 is located below the pin inlet pipe 28. The ejector pin 30 passes through one end of the pin channel seat 27. A mating seat 29 is installed at the other end of the pin channel seat 27. A pin outlet hole is opened at the end of the mating seat 29 closest to the fixture 1. The pin 30 can pass through the pin outlet hole, which is connected to the pin channel. After the guide pin 23 passes through the pin groove 21, the pin 40 is fed in from the pin inlet tube 28, causing the pin 40 to slide into the hole seat 29. The hole seat 29 moves closer to the hinge arm 36, and then the pin 40 is pushed into the hinge arm 36 by the pin 30, so that the pin 40 limits the spring 39. During the process of the pin 40 being pushed into the hinge arm 36, the pin 40 contacts the guide pin 23 and pushes the guide pin 23 out at the same time, so that the pin 40 can be inserted into the hinge arm 36 more stably.

[0027] It is worth noting that a fifth cylinder 31 is installed on the pin channel connecting seat 25 in this embodiment. The cylinder shaft of the fifth cylinder 31 is connected to the top pin 30. A sixth cylinder 33 is installed on the pin channel connecting seat 25 on one side of the fifth cylinder 31. A connecting block 32 is provided on one side of the third slider 26. The cylinder shaft of the sixth cylinder 33 is connected to the connecting block 32. The pin channel seat 27 can reciprocate under the drive of the sixth cylinder 33, so that the hole seat 29 can be brought closer to the hinge arm 36, reducing the gap so that the pin 40 can be pushed into the hinge arm 36. The fifth cylinder 31 can then drive the top pin 30 to move and push the pin 40 in.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
