Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] See Figure 1 , Figure 2 and Figure 3 This utility model provides a high-precision foam inlaid steel wire positioning structure, including: a worktable 1, a first through groove 2 provided on the worktable 1, a one-way screw 3 rotatably provided in the first through groove 2, a sliding block 4 provided on the one-way screw 3, one end of the one-way screw 3 passing through the side wall of the first through groove 2 and connected to a first motor 5, the first motor 5 being connected to the side wall of the worktable 1, a sliding seat 6 provided on the sliding block 4, and the top surface of the sliding seat 6 being connected to a support base 10 through a cylinder 7;

[0031] The adjusting assembly 9 includes a fixed block 901, a bidirectional lead screw 902, a moving block 903, and a moving rod 904. The fixed blocks 901 are disposed on both sides of the top surface of the support base 10. The bidirectional lead screw 902 is rotatably disposed between the two fixed blocks 901. The bidirectional lead screw 902 is connected to the second motor 11, which is disposed on the support base 10. The moving blocks 903 are symmetrically disposed on the bidirectional lead screw 902. The moving rods 904 are disposed on the side walls of the moving blocks 903. Clamping assemblies 12 are disposed on the opposite side walls of the two moving rods 904. The clamping assemblies 12 are used to fix the wire mesh 8.

[0032] The workbench 1 has support legs on its bottom surface, a unidirectional lead screw 3 has an external thread, and a sliding block 4 has an internal thread that matches the external thread. There are two moving blocks 903 and two moving rods 904. The bidirectional lead screw 902 has two threaded areas with opposite directions, and the moving block 903 has a thread that matches the threaded area.

[0033] Specifically, first, the second motor 11 is started, the bidirectional lead screw 902 rotates between the two fixed blocks 901, the moving blocks 903 move towards or away from each other on the bidirectional lead screw 902, and the moving rods 904 move synchronously until the distance between the two clamping components 12 on the two opposing moving rods 904 reaches the required distance for clamping the wire mesh 8.

[0034] Then, control cylinder 7 to position support base 10 at a suitable height, and fix both ends of wire mesh 8 onto clamping assembly 12.

[0035] Finally, the first motor 5 is started, which drives the one-way screw 3 to rotate in the first through slot 2. The sliding block 4 moves on the one-way screw 3, and the sliding seat 6 moves synchronously with the cylinder 7 and the support seat 10. The moving rod 904 moves accordingly, and the position of the wire mesh 8 driven by the clamping component 12 on it also moves accordingly. Then, the height of the wire mesh 8 is adjusted by the cylinder 7, and the wire mesh 8 is placed in the foaming mold for subsequent foaming processes.

[0036] It should be noted that the connection position between the moving rod 904 and the clamping assembly 12 has a downward protrusion. The height of this connection position can be preset according to the depth of the foaming mold to adapt to the foaming mold.

[0037] In some embodiments, the clamping assembly 12 includes a fixed base 1201, an abutment block 1202, a pressure block 1203, and a screw 1204. The fixed base 1201 is connected to the side wall of the moving rod 904. The abutment block 1202 is fixedly disposed at the bottom of the fixed base 1201. The pressure block 1203 is slidably disposed on the side wall of the fixed base 1201. The screw 1204 is rotatably disposed inside the fixed base 1201 and is screwed to the pressure block 1203. The top end of the screw 1204 passes through the fixed base 1201 and is connected to the rotating rod 13.

[0038] The fixed base 1201 is screwed to the side wall of the moving rod 904. The rotating rod 13 rotates to drive the screw 1204 to rotate, which drives the pressure block 1203 to slide on the fixed base 1201. The bottom surface of the pressure block 1203 and the top surface of the fixed base 1201 respectively abut against the connecting end 23 of the wire mesh 8 and clamp the connecting end 23 of the wire mesh 8.

[0039] In some embodiments, the support base 10 is provided with a second through groove 14, and the bottom end of the movable block 903 is at least partially located within the second through groove 14. When the movable block 903 moves on the bidirectional screw 1204 driven by the threaded rotation of the screw, a small portion of the bottom end of the movable block 903 is located within the second through groove 14, which limits the movement of the movable block 903 on the horizontal plane, thus ensuring smoother movement.

[0040] See Figure 4 and Figure 6 In some embodiments, a gear 15 is provided at the top of the rotating rod 13. The gear 15 meshes with the toothed plate 16. The toothed plate 16 is provided on the sliding rod 17, which is slidably provided on the top surface of the worktable 1.

[0041] As the sliding block 4 moves within the first through slot 2, the gear 15 moves from one side of the toothed plate 16 to the other. During this movement, the protruding teeth on the toothed plate 16 cause the gear 15 to rotate, which in turn drives the rotating rod 13 to rotate, thus driving the pressure block 1203 to move on the fixed seat 1201 and clamp the wire mesh 8. The sliding position of the sliding rod 17 is adjusted according to the distance between the two moving rods 904.

[0042] In some embodiments, a first groove 18 is symmetrically arranged on the top surface of the workbench 1, and a slot block 19 is provided at the bottom end of the sliding rod 17. The slot block 19 slides in the first groove 18, and the sliding rod 17 is slidably connected to the first groove 18 through the slot block 19.

[0043] In this process, the second motor 11 drives the bidirectional lead screw 902 to rotate, and the moving block 903 moves on the bidirectional lead screw 902. The distance between the two sets of adjusting components 9 changes, thereby adjusting the sliding position of the sliding rod 17. The slot block 19 moves in the first groove 18, so that the gear 15 and the toothed plate 16 remain engaged. Then, the first motor 5 drives the sliding block 4 to move in the first through groove 2. The sliding seat 6, the support seat 10 and the adjusting components 9 on it also move synchronously. The gear 15 engages and moves on the toothed plate 16. The rotating rod 13 rotates, driving the screw 1204 to rotate in the fixed seat 1201. The pressure block 1203 moves downward on the side wall of the fixed seat 1201. The fixed block 901 and the pressure block 1203 clamp the connecting end 23 of the wire mesh 8.

[0044] It should be noted that the one-way lead screw 3 drives the sliding block 4 to move along a fixed length within the first through slot 2. When the sliding block 4 moves away from the first motor 5 and reaches the side wall of the through slot, the clamping assembly 12 clamps the connecting end 23 of the wire mesh 8. Since the height of the sliding rod 17 is fixed, when the telescopic end of the cylinder 7 extends upward and reaches the maximum stroke of the cylinder 7, the gear 15 meshes with the toothed plate 16. When the telescopic end of the cylinder 7 retracts, the gear 15 disengages from the toothed plate 16.

[0045] In some embodiments, the bottom surface of the sliding seat 6 is provided with sliding edges 20 at both ends, and the top surface of the worktable 1 is symmetrically provided with second grooves 21. The sliding edges 20 are located in the second grooves 21. When the sliding block 4 moves in the first through groove 2, the sliding edges 20 move in the second grooves 21. Through the cooperation between the sliding edges 20 and the second grooves 21, the movement of the sliding seat 6 on the worktable 1 is more stable, and the accuracy of wire placement is improved.

[0046] In some embodiments, the abutment block 1202 is provided with a fixing groove 22, which is used to position the connecting end 23 of the wire mesh 8. The fixing groove 22 matches the connecting end 23 of the wire mesh 8. When the abutment blocks 1202 on both sides are specifically adjusted to the clamping distance of the wire mesh 8, the fixing grooves 22 on both sides will limit the connecting end 23 on both sides of the wire mesh 8 to prevent the wire mesh 8 from moving.

[0047] It should be noted that the connecting end 23 of the wire mesh 8 is the position used in subsequent processes to connect with the car seat frame in order to strengthen the strength of the car seat and improve its shock absorption performance.

[0048] See Figure 4In some embodiments, the rotating shaft of the second motor 11 is provided with an active bevel tooth 24, which meshes with a driven bevel tooth 25, which is sleeved on the bidirectional lead screw 902. The rotation of the rotating shaft of the second motor 11 drives the active bevel tooth 24 to rotate, and the driven bevel tooth 25 rotates synchronously, providing rotational power to the bidirectional lead screw 902.

[0049] In some embodiments, a groove 26 is provided on the inner sidewall of the first through groove 2, and a slider 27 is provided on the outer sidewall of the sliding block 4. The slider 27 slides within the groove 26, and the sliding block 4 is slidably connected to the groove 26 via the slider 27. The cooperation between the slider 27 and the groove 26 makes the movement of the sliding block 4 within the first through groove 2 more stable.

[0050] In some embodiments, the first motor 5 is mounted on a fixed frame 28, which is connected to a connecting frame 29, which is fixed to the side wall of the worktable 1. Through the arrangement of the fixed frame 28 and the connecting frame 29, the first motor 5 can make direct contact with the worktable 1, making it easier to disassemble and maintain the first motor 5, which has a larger load capacity compared to the second motor 11.

[0051] Work process

[0052] First, start the second motor 11. The bidirectional lead screw 902 rotates between the two fixed blocks 901. The moving blocks 903 move towards each other on the bidirectional lead screw 902. The bottom ends of the moving blocks 903 move towards each other in the second through slot 14. The moving rods 904 move synchronously until the distance between the two clamping components 12 on the two opposing moving rods 904 reaches the required distance for clamping the wire mesh 8.

[0053] Then, the extension end of the control cylinder 7 is extended so that the gear 15 is at the same height as the gear plate 16 and meshes with it.

[0054] Next, the first motor 5 is started, the one-way screw 3 rotates in the first through slot 2, the sliding block 4 moves on the one-way screw 3 towards the sliding rod 17, the sliding seat 6 moves synchronously with the cylinder 7 and the support seat 10 on it, the moving rod 904 moves accordingly, the convex teeth on the toothed plate 16 drive the gear 15 to rotate, the rotating rod 13 rotates, driving the screw 1204 to rotate, driving the pressure block 1203 to move downward on the side wall of the fixed seat 1201. As the moving rod 904 moves, the pressure block 1203 and the fixed block 901 clamp and fix the connecting tube of the wire mesh 8.

[0055] Finally, the telescopic end of the control cylinder 7 retracts, the height of the wire mesh 8 connected to the clamping assembly 12 is adjusted, the gear 15 moves downward, disengages from the toothed plate 16, and places the wire mesh 8 into the foaming mold for subsequent foaming processes.

[0056] The clamping assembly 12 is driven by the first motor 5 to move and clamp the wire mesh 8 through the interaction of the rotating rod 13 and gear 15 on the clamping assembly 12, and the toothed plate 16 on the sliding rod 17. The second motor 11 drives the horizontal relative position of the two clamping assemblies 12, and the vertical height of the clamping assembly 12 is controlled by the lifting and lowering of the cylinder 7 to accommodate wire mesh 8 of different specifications, thus increasing the applicability of this equipment in semi-exposed wire inlay processes.
