Description

Technical Field

[0001] This utility model belongs to the technical field of metal parts processing equipment, and in particular relates to an automatic feeding mechanism for the production of seat belt gears. Background Technology

[0002] Currently, the main protective measures for automobiles include seat belts, anti-collision body structures, and airbag protection systems. Car seat belts are a traditional passive safety feature that ensures safe driving. In the event of a violent collision, the pretensioner tightens the seat belt, restricting the position of the driver or passengers and preventing them from colliding with objects inside the vehicle such as the steering wheel, windshield, seat back, and doors. The seat belt gear is one of the most critical components used in car seat belts and their systems. When the car seat belt is used for cushioning, this gear needs to rotate to provide cushioning force and ultimately hold the seat belt in place, thus highlighting its importance.

[0003] The current production process for seat belt gears involves first stamping sheet metal on a vertical punch press, then phosphating it, followed by machining on a vertical three-station cold forging press, then vibrating and cleaning the forged parts, and finally welding two identical small gears together before electroplating. In this process, each step is relatively independent, requiring manual transfer of parts between steps, resulting in wasted manpower and resources. The subsequent welding process, in particular, requires manual loading, which is time-consuming. Consequently, production efficiency and quality cannot keep pace with customer demands and production rhythm. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an automatic feeding mechanism that can orderly transfer the half gear disk from one station to another, reduce manual intervention, improve the efficiency of parts turnover, and lay the foundation for fully automated welding.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] An automatic feeding mechanism includes a worktable, a feeding and positioning mechanism, and a rotating clamping mechanism fixed on the worktable. The feeding and positioning mechanism includes a support base A, a first loading platform, a first feeding cylinder, a first feeding block, a second loading platform, a second feeding cylinder, and a second feeding block.

The positioning block; the second loading platform is fixed to one side of the first loading platform, and a second feeding cylinder is fixed to one side of the second loading platform. The piston rod of the second feeding cylinder is fixed to the second feeding block and drives the second feeding block to reciprocate along the length of the second loading platform; the rotating clamping mechanism includes a support base B, a vertical moving cylinder, a rotating cylinder, and a clamping assembly. The vertical moving cylinder is fixed to the support base B, and the rotating cylinder is fixed to the piston rod of the vertical moving cylinder by a mounting support plate. A connecting plate is fixed to the output end of the rotating cylinder, and two clamping assemblies are respectively fixed to both ends of the connecting plate.

[0007] As a preferred embodiment, the clamping assembly includes a gripper cylinder, grippers, and a top block. The gripper cylinder is fixed to the end of the connecting plate, and the two grippers are connected to the gripper cylinder. The top block is also fixed to the end of the connecting plate and is located between the two grippers.

[0008] As a preferred embodiment, the top of the support base A is also fixed with a mounting support plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention employs a feeding and positioning mechanism and a rotating clamping mechanism. The feeding and positioning mechanism uses two sets of feeding cylinders and feeding blocks arranged at an angle to each other to cooperate in feeding, enabling the entire mechanism to meet the needs of more confined spaces. The feeding position can be flexibly adjusted, making it more widely applicable.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] like Figures 1 to 6 As shown, an automatic feeding mechanism includes a worktable 1, a feeding and positioning mechanism 2, and a rotating clamping mechanism 3 fixed on the worktable 1. The feeding and positioning mechanism 2 includes a support base A21, a first loading platform 27, a first feeding cylinder 23, a first feeding block 26, a second loading platform 28, a second feeding cylinder 29, and a second feeding block 210. The first loading platform 27 is fixed to the top of the support base A21. The first feeding cylinder 23 is disposed at one end of the first loading platform 27. The piston rod of the first feeding cylinder 23 is fixed to the first feeding block 26 and drives the first feeding block 26 to reciprocate along the length of the first loading platform 27. The other end of the first loading platform 27 is provided with a side fixing... Positioning cylinder 211 and side positioning block 212; the second loading platform 28 is fixed to one side of the first loading platform 27, and a second feeding cylinder 29 is fixed to one side of the second loading platform 28. The piston rod of the second feeding cylinder 29 is fixed to the second feeding block 210 and drives the second feeding block 210 to reciprocate along the length direction of the second loading platform 28; a mounting support plate A22 is also fixed to the top of the support base A21. The first loading platform 27 is fixed to the support base A21 through a side bracket and a gap is left between it and the mounting support plate A22. A guide rail 24 is fixed on the mounting support plate A22. A slider 25 is provided on the guide rail 24. One end of the first feeding block 26 is fixed to the slider 25.

[0030] The first loading platform 27 has a baffle strip on the side away from the second loading platform 28, and an incoming material detection sensor A213 is fixed on the baffle strip. The second loading platform 28 also has a baffle strip on the side near the second feeding cylinder 29, and a limiting strip is provided on the other side of the second loading platform 28 near the first loading platform 27, with an L-shaped stop at the top of the limiting strip. An incoming material detection sensor B214 is fixed on the baffle strip of the second loading platform 28.

[0031] The first loading platform 27 and the second loading platform 28 are integrally formed, so there is no gap between them and no height difference exists. The half gear disk 100 can be pushed more smoothly from the second loading platform to the first loading platform and finally enter the designated position.

[0032] The working process of the above mechanism is as follows: When the incoming material detection sensor B detects the part, the second feeding cylinder 29 pushes the half gear disk to the position of the incoming material detection sensor A through the second feeding block 210 and then retracts. After the incoming material detection sensor A detects the half gear disk, the first feeding cylinder pushes the part to the side positioning block 212 through the first feeding block 26 and clamps it by the side positioning cylinder 211. The bottom of the first loading platform 27 is also equipped with two positioning sensors. When the positioning sensor detects the half gear disk, the next action is performed. If the positioning sensor detects that the half gear disk is not in position, the side positioning cylinder 211 retracts, the first feeding cylinder drives the first feeding block to retract, and then pushes the part again. The side positioning cylinder clamps it again, and the positioning is completed.

[0033] like Figure 5 and Figure 6 As shown, the rotating clamping mechanism 3 includes a support base B31, a vertical moving cylinder 32, a rotating cylinder 34, and clamping components. The vertical moving cylinder 32 is fixed on the support base B31. The rotating cylinder 34 is fixed to the piston rod of the vertical moving cylinder 32 through a mounting support plate B33. The rotating cylinder 34 is fixed on the mounting support plate B33. A connecting plate 35 is fixed to the output end of the rotating cylinder 34. Two clamping components are respectively fixed to both ends of the connecting plate 35.

[0034] The clamping assembly includes a gripper cylinder 36, grippers 37, and a top block 38. The gripper cylinder 36 is fixed to the end of the connecting plate 35, and the two grippers 37 are connected to the gripper cylinder 36. The top block 38 is also fixed to the end of the connecting plate 35 and is located between the two grippers 37.

[0035] The working process of the above mechanism is as follows: When the positioning sensor detects that the half gear disk 100 is in position, the up-down movement cylinder descends to the position, and one gripper cylinder drives the gripper to clamp the half gear disk 100. At this time, the top block also supports the half gear disk 100. The top block can prevent the part from loosening during the clamping and movement process. At the same time, another gripper cylinder drives the gripper to release the gripper and put the half gear disk 100 into the next process. Then, cylinder B drives the positioning column to retract, and cylinder A drives the push block to retract. The up-down movement cylinder rises to the position, and the rotation cylinder rotates to the position, so that the half gear disk 100 reaches the next process again. This cycle can realize the continuous transfer of the half gear disk 100 to the next process, which greatly improves the turnover efficiency of the parts.

[0036] like Figure 1 As shown, a detection mechanism 4 is also fixed on the worktable. The detection mechanism 4 includes a support rod base 41, an adjusting block 42, and a laser sensor. The support rod base 41 is fixed on the worktable 1, at least one adjusting block 42 is fixed on the top of the support rod base 41, and the laser sensor is fixed to the adjusting block 42 and aligned with the unloading point of the rotating clamping mechanism 3. After the preceding actions are completed, the laser sensor detects whether the part is placed in place and performs corresponding processing.
