Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, specifically a method for forming a rotating automotive seat. Background Technology

[0002] Currently, car seats are generally designed with a concave shape based on ergonomic principles to ensure comfort. This places high demands on the flatness of the structure and the precision of the molding of each tilt angle. However, the inspection of common rotating seats is not accurate enough, resulting in poor molding effects. The corresponding operating procedures and methods are also not fully applicable to the requirements of testing and molding the flatness of the concave structure and the tilt angle of each layer. Summary of the Invention

[0003] The purpose of this invention is to provide a method for molding a rotating car seat, in order to solve the problems that the detection of common rotating seats is not accurate enough, resulting in poor molding effect, and that the corresponding operation process and method cannot be fully applied to the requirements of detecting the flatness of the concave structure and the tilt angle of each layer.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a method for forming a rotating car seat, wherein the forming fixture for the forming method includes a worktable, a guardrail, a first clamp, a second clamp, a positioning pin, and a sensor. A positioning seat is mounted in the middle of the worktable, and a lifting device is provided on the outside of the positioning seat. The sensor is mounted on the first clamp and / or the second clamp and the positioning seat. The forming method includes the following steps:

[0005] S1. Positioning of workpiece: Press the rotating seat into the groove of the enclosure and position it on the output shaft of the lifting device. The first clamp and the second clamp are pressed onto the rotating seat. The positioning seat passes through the central through hole of the rotating seat and is positioned on the worktable.

[0006] S2, Component assembly: The positioning pin is inserted into the outer through hole of the recessed structure in the middle of the rotating seat and snapped onto the worktable. The sensor is assembled on the first clamp and / or the second clamp and the positioning seat, with its probe abutting against the upper surface of the rotating seat.

[0007] S3. Flatness detection: The lifting device lifts or pulls down the outer side of the central through hole of the rotating seat. When the height of the top surface of the output shaft of the lifting device at the end of the lifting is the same as the height of the outer side of the same layer on the concave structure of the rotating seat, the values ​​of the sensors in the center and the outer side are recorded. When the difference between the two is within the set range, it indicates that the flatness is qualified; otherwise, subsequent correction is performed.

[0008] S4. Correction and shaping: The lifting device performs a reciprocating pushing operation on the rotating seat in the opposite direction of bending.

[0009] S5. Molding and unloading: The rotating seats that have been corrected in step S4 are inspected in step S3. For those that do not meet the standards, steps S3 and S4 are repeated. The qualified rotating seats are removed in reverse order of steps S1 and S2.

[0010] As a further description of the above technical solution:

[0011] The enclosure is equipped with positioning bolts that penetrate the side edge of the rotating seat.

[0012] As a further description of the above technical solution:

[0013] The insertion rod at the bottom of the positioning seat is slidably disposed in the central through hole and engaged with the card seat on the worktable. A connecting platform is provided in the middle of the positioning seat, the sensor is positioned on the top surface of the connecting platform, and the probe passes through the hole of the connecting platform.

[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0017] The workbench is provided with several positioning fixtures corresponding to the positioning pins and sensors. The positioning fixtures are positioning clamps or storage boxes.

[0018] As a further description of the above technical solution:

[0019] The central recessed structure of the rotating seat is distributed in multiple layers from the inside out. In steps S3 and S4, the flatness of the rotating seat is detected and corrected layer by layer from the outside to the inside.

[0020] As a further description of the above technical solution:

[0021] When performing the inner layer inspection and correction of the recessed structure, the positioning pin of the outer layer is fixed on the worktable to position the top or bottom surface of the recessed structure of that layer.

[0022] As a further description of the above technical solution:

[0023] The setting range of the sensor value difference between the center and the outer side in step S3 is based on the maximum upward or downward tilt angle of each layer of the rotating seat recess structure corresponding to the flatness qualification standard.

[0024] As a further description of the above technical solution:

[0025] The sensor is a pressure sensor. In step S3, when the value of the outer sensor is high, the rotating seat is corrected upwards; otherwise, it is corrected downwards. In this embodiment, the output shafts of the first clamp, the second clamp, and the lifting device are at the same distance from their corresponding probes, and their contact points with the rotating seat are collinear. All sensors are positioned at the same height.

[0026] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0027] This invention uses clamps to position the rotating seat and form a rotation fulcrum. A lifting device lifts the rotating seat, and a pressure sensor senses the height of the corresponding position on the product, enabling precise detection of the vertical curvature of the product. The flatness of the rotating seat is corrected by the reciprocating push and pull of the lifting device. This method of detecting and forming is also applicable to the flatness detection and correction of each layer of a stepped concave structure. Positioning pins limit the deformation direction of the corresponding layer of the concave structure during detection and correction, ensuring stable and accurate detection and correction operations for each layer.

When the rotating seat is positioned, the pressure attachment is rotated onto it, and the side bolts abut against the side of the pressure attachment, thus completing the structural shaping and positioning of the rotating seat.

[0039] The molding method includes the following steps:

[0040] S1. Positioning of workpiece: Press the rotary seat 100 into the groove of the enclosure 2 and position it on the output shaft of the lifting device. The first clamp 3 and the second clamp 4 are pressed onto the rotary seat 100.

The sensor 8 is assembled on the first clamp 3 and / or the second clamp 4 and the positioning seat 6, and its probe 81 abuts against the upper surface of the rotating seat 100.

[0042] S3. Flatness detection: The lifting device lifts or pulls down the outer side of the central through hole of the rotating seat 100. When the height of the top surface of the output shaft of the lifting device at the end of the lifting is the same as the height of the outer side of the same layer on the concave structure of the rotating seat 100, the values ​​of the central and outer sensors 8 are recorded. When the difference between the two is within the set range, it indicates that the flatness is qualified; otherwise, subsequent correction is performed.

[0043] S4. Correction and shaping: The lifting device performs a reciprocating pushing operation on the rotating seat 100 in the opposite direction of bending.

[0044] S5. Molding and unloading: The rotating seat 100 that has been corrected in step S4 is inspected in step S3. For those that do not meet the standards, steps S3 and S4 are repeated. The qualified rotating seats 100 are taken out in reverse order of steps S1 and S2.

[0050] When performing the inner layer inspection and correction of the recessed structure, the positioning pin 7 of the outer layer is fixed on the worktable 1 to position the top or bottom surface of the recessed structure of that layer.

[0051] The setting range of the numerical difference between the central and outer sensors 8 in step S3 is based on the maximum upward or downward tilt angle of each layer of the concave structure of the rotating seat 100 corresponding to the flatness qualification standard.

[0052] The sensor 8 is a pressure sensor. In step S3, when the value of the outer sensor 8 is high, the rotating seat 100 is corrected upwards; otherwise, it is corrected downwards. In this embodiment, the output shafts of the first clamp 3, the second clamp 4, and the lifting device are at the same distance from the corresponding probe 81, and their contact points with the rotating seat 100 are collinear. Furthermore, all sensors 8 are positioned at the same height.
