Technical Field

[0001] This utility model relates to the technical field of automotive seat production equipment, specifically a seat slide rail rolling and riveting device. Background Technology

[0002] In the production of car seats, the riveting of the seat rails is a critical process, as its quality directly affects the safety and lifespan of the seat. Traditional seat rail riveting methods often use stamping and riveting, which has problems such as low riveting precision, stress concentration at the riveting joint, and significant damage to the rail material.

[0003] Roll riveting, as a novel riveting process, offers advantages such as high riveting precision, uniform stress distribution, and minimal material damage, and is increasingly being used in seat rail riveting. However, existing roll riveting devices are complex in structure, inconvenient to operate, and lack high positioning accuracy, affecting riveting quality and production efficiency.

[0004] Therefore, a seat slide rail rolling and riveting device with simple structure, accurate positioning and convenient operation is needed. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, this utility model provides a seat slide rail rolling riveting device, including a frame 1, a drive mechanism 2 fixedly installed on the frame 1, the output end of the drive mechanism 2 being connected to the rolling riveting mechanism 4 through a transmission component 3, the rolling riveting mechanism 4 including a riveting component 41 and a mounting base 42, the riveting component 41 being rotatably installed on the mounting base 42, the mounting base 42 being installed on one side surface of a movable frame 6, the movable frame 6 using a hydraulic mechanism installed on the surface of the frame 1 as a power source, the frame 1 also being provided with a positioning mechanism 7 for positioning the seat slide rail, the positioning mechanism 7 including a positioning block 71 and a clamping component 72, the positioning block 71 being fixed on the frame 1, the clamping component 72 cooperating with the positioning block 71 to clamp and position the seat slide rail;

[0027] The transmission component 3 is a gear transmission component, including a driving gear 31 and a driven gear 32. The driving gear 31 is fixedly connected to the output end of the drive mechanism 2, and the driven gear 32 meshes with the driving gear 31. The driven gear 32 is fixedly connected to the mounting base 42 through a connecting shaft.

[0028] The clamping assembly 72 includes a cylinder 721 and clamping blocks 722. The cylinder 721 is fixed on the frame 1. The piston rod of the cylinder 721 is fixedly connected to the clamping blocks 722. There are four clamping blocks 722, which are arranged on both sides of the inner wall of the slot in the positioning block 71.

[0029] The operator places the seat rail to be riveted into the positioning groove 711 of the positioning block 71, ensuring a tight fit between the seat rail and the positioning groove 711. The clamping assembly 72 is activated, extending the piston rod of the cylinder 721 and driving the four clamping blocks 722 to move from both sides of the inner wall of the groove in the positioning block 71 towards the seat rail until the clamping blocks 722 are in close contact with the seat rail, completing the clamping and positioning of the seat rail. The drive mechanism 2 and the hydraulic mechanism are then activated. The hydraulic mechanism drives the moving frame 6 to move along the guide block 5 towards the seat rail. Simultaneously, the drive mechanism 2 drives the drive gear 31 to rotate, which in turn drives the driven gear 32 to rotate. Power is transmitted to the mounting base 42 via the connecting shaft, causing the riveting piece 41 to rotate accordingly. When the riveting piece 41 contacts the riveting position of the seat rail, the roll riveting operation begins.

[0030] It should be noted that the drive mechanism 2 is a servo motor. The servo motor is fixedly mounted on the other side surface of the moving frame 6 through a motor mount. The number of the drive mechanism 2 is matched with the number of the riveting parts 41. The drive mechanism 2 uses a servo motor, which is matched with the number of the riveting parts 41, and can drive multiple riveting positions simultaneously.

[0031] The rolling riveting mechanism 4 also includes a pressure sensor, which is set between the mounting base 42 and the transmission assembly 3 to detect the pressure of the riveted part 41 on the seat slide rail. The pressure sensor in the rolling riveting mechanism 4 can detect the pressure of the riveted part 41 on the seat slide rail in real time, which makes it easy for the operator to adjust the hydraulic mechanism according to the actual situation, so as to ensure that the riveting pressure is within a suitable range and avoid poor riveting due to excessive or insufficient pressure.

[0032] The positioning block 71 is provided with a positioning groove 711 that matches the seat slide rail, ensuring that the seat slide rail will not shift during the riveting process.

[0033] The frame 1 is also equipped with a T-shaped guide block 5, and the moving frame 6 slides on the surface of the guide block 5, which improves the stability of the moving frame 6.

[0034] The bottom of the frame 1 is equipped with adjusting feet 8, which can be used to adjust the level of the device and ensure the overall stability of the device.

[0035] Working principle and process: The operator places the seat rail to be riveted into the positioning groove 711 of the positioning block 71, ensuring a tight fit between the seat rail and the positioning groove 711. The clamping assembly 72 is activated, extending the piston rod of the cylinder 721, which drives the four clamping blocks 722 from both sides of the groove in the positioning block 71 towards the seat rail until the clamping blocks 722 are in close contact with the seat rail, completing the clamping and positioning of the seat rail. The drive mechanism 2 and hydraulic mechanism are then activated. The hydraulic mechanism drives the moving frame 6 to move along the guide block 5 towards the seat rail. Simultaneously, the drive mechanism 2 drives the drive gear 31 to rotate, which in turn drives the driven gear 32 to rotate. Power is transmitted to the mounting base 42 via the connecting shaft, causing the riveting part 41 to rotate accordingly. When the riveting part 41 contacts the riveting position of the seat rail, the roll riveting operation begins. During the riveting process, the pressure sensor monitors the riveting pressure in real time and transmits the data to the control system. If the pressure exceeds or falls below the preset value, the control system can issue an alarm and control the hydraulic mechanism to adjust the pressure of the moving frame 6 to ensure that the riveting pressure is within a suitable range. After the riveting operation is completed, the drive mechanism 2 stops working, and the hydraulic mechanism drives the moving frame 6 to move the riveted part 41 away from the seat slide rail. The piston rod of the cylinder 721 of the clamping assembly 72 retracts, causing the clamping block 722 to release the seat slide rail. The operator then removes the riveted seat slide rail from the positioning groove 711, completing one riveting cycle.
