Description

Technical Field

[0001] This invention relates to the field of spring assembly technology, and more specifically to a spring assembly device. Background Technology

[0002] In the assembly and production of spring-related products, some core components have a compact internal space structure and narrow installation channels, which brings significant challenges to the assembly operation.

[0003] For certain specifications of lower cover-type parts, there are mounting slots and matching mating slots inside. The annular spring must be precisely assembled into the mounting slot, and the rubber pin must be properly fitted into the mating slot. Because the mounting hole diameter for these parts is relatively small, operators cannot directly access the hole with their hands. This not only results in low assembly efficiency, making it unsuitable for mass production, but also makes it difficult to guarantee assembly accuracy. This can easily lead to quality issues such as improper spring installation, misalignment of the rubber pin, spring deformation, or detachment, directly affecting the subsequent performance of the product.

[0057] The conveying assembly includes a second vertical plate 69, a first rodless cylinder 64, a rotary motor 65, a rotating plate 66, a first vertical push cylinder 67, and a parallel cylinder 68.

[0058] The second upright plate 69 is fixedly installed on the upper left side of the base plate 1; the first rodless cylinder 64 is fixedly installed on the rear end of the second upright plate 69; the rotary motor 65 is fixedly installed on the upper end of the moving end of the first rodless cylinder 64; the rotating plate 66 is rotatably installed on the lower end of the moving end of the first rodless cylinder 64; the output end of the rotary motor 65 is fixedly connected to the rotating plate 66.

[0059] The lower end of the rotating plate 66 is symmetrically fixed with the first vertical push cylinder 67 on both the left and right sides;

[0060] The output end of the first vertical push cylinder 67 is fixedly connected to the parallel cylinder 68;

[0061] The tight pressing mechanism 7 includes a pneumatic slide 71, a contour pressing block 72, a pressing block 73, a vertical guide rod 74, a reset spring 75, a laser sensor 76, and a third upright plate 77.

[0062] The third upright plate 77 is fixedly installed on the upper rear side of the base plate 1; the pneumatic slide table 71 is fixedly installed on the front side of the third upright plate 77; the contouring pressure block 72 is fixedly installed on the lower side of the moving end of the pneumatic slide table 71; the vertical guide rod 74 is slidably connected to the front side of the contouring pressure block 72; a reset spring 75 is wound around the lower outer side of the vertical guide rod 74; one end of the reset spring 75 is fixedly connected to the vertical guide rod 74; the other end of the reset spring 75 is fixedly connected to the contouring pressure block 72; and a pressing block 73 is fixedly installed at the lower end of the vertical guide rod 74.

[0063] The laser sensor 76 is fixedly installed at the upper middle part of the cam divider 2;

[0064] In this invention, the operator places the lower cover 9 containing the spring 10 into the fixed seat 41 at the loading and unloading station and limits it with the limiting rod 42 and the limiting block 43.

[0065] Subsequently, the cam divider 2 and the rotary disk 3 drive the fixed seat 41 to move clockwise to the bottom of the contact block 55 of the first torque testing mechanism. Then, the first servo slide assembly 51 controls the torque testing motor 52 to move downward until the contact block 55 contacts the spring 10 and continuously compresses the spring 10. Then, the torque testing motor 52 controls the drive shaft 53 to rotate, so that the contact block 55 follows the drive shaft 53 to drive the spring 10 to rotate. During the rotation, the dynamic torque sensor 54 will detect the torsion of the drive shaft 53 to determine whether the spring 10 is in the correct assembly state.

[0066] At the same time, the vibratory feeder 61 controls the rubber PIN to move forward in a horizontal state into the two receiving slots 621 on the rear side of the transfer cylinder 62. Then, the drive motor 63 drives the transfer cylinder 62 to rotate upward 90 degrees, so that the rubber PIN is in a vertical state.

[0067] Subsequently, the two first vertical push cylinders 67 push the parallel cylinder 68 downward, and then the parallel cylinder 68 clamps and fixes the two rubber pins. The first vertical push cylinder 67 drives the parallel cylinder 68 to reset upward, and removes the rubber pins from the receiving groove 621.

[0068] When the fixed seat 41 moves to the right of the position of the second upright plate 69, the first rodless cylinder 64 then drives the rotating plate 66 to move to the right until the rotating plate 66 moves above the fixed seat 41. Then the drive motor 63 controls the rotating plate 66 to rotate, so that the rubber PIN is aligned with the mating groove 92 of the lower cover 9.

[0069] Subsequently, the first vertical push cylinder 67 controls the parallel cylinder 68 to move downward, installing the rubber pin into the mating groove 92;

[0070] Then the rotary table 3 continues to rotate, causing the lower cover 9 to move below the contouring block 72. Then the pneumatic slide table 71 controls the contouring block 72 and the pressing block 73 to move downwards simultaneously. The pressing block 73 presses against the lower cover 9, causing the vertical guide rod 74 to move upwards and compress the reset spring 75, thus preventing the lower cover 9 from shifting.

[0071] During the movement, the contouring block 72 will come into contact with the rubber PIN and press it into the mating groove 92;

[0072] Then the pneumatic slide 71 drives the contouring block 72 and the pressing block 73 to reset upwards. Then the laser sensor 76 can detect whether the height of the pressed rubber PIN has completed the tight pressing operation.

[0073] Then the rotating disk 3 rotates, causing the lower cover 9 to move to the second torque testing mechanism for re-inspection.

[0074] Example 3: In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the oil dispensing mechanism 8 includes a fourth vertical plate 81, a second vertical push cylinder 82, an oil dispensing nozzle 84, and a second rodless cylinder 85; the fourth vertical plate 81 is fixedly installed on the upper right side of the base plate 1; the second rodless cylinder 85 is fixedly installed on the front end of the fourth vertical plate 81; the second vertical push cylinder 82 is fixedly installed on the moving end of the second rodless cylinder 85; the output end of the second vertical push cylinder 82 is fixedly connected to the oil dispensing nozzle 84; the oil dispensing nozzle 84 is connected to an external oil pump through a liquid guide pipe;

[0075] In this invention, the rotating disk 3 drives the lower cover 9 to move below the oil nozzle 84, the second rodless cylinder 85 controls the second vertical push cylinder 82 to move to the left, and then the second vertical push cylinder 82 drives the oil nozzle 84 to move downward, so that the oil nozzle 84 moves into the mounting groove 91 and contacts the spring 10. Then the external oil pump discharges oil through the oil nozzle 84 into the mounting groove 91 to complete the oiling operation.

[0076] Finally, the rotary table 3 drives the lower cover 9 back to the loading and unloading station. Then, the operator moves the lower cover 9, which has completed the assembly of the spring 10 and the rubber PIN, out and puts in the next lower cover 9 that needs to be assembled.

[0077] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
