[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment 1:

[0025] This embodiment provides a main fixture structure for 3D sewing of automobile seat sheets, such as Figure 1-3 As shown, it includes an upper main clamp 1 and a lower main clamp 2. The upper main clamp 1 is slidably arranged below the upper bracket 4 by connecting the slide rail 3. The lower main clamp 2 is fixed above the lower bracket 5. The upper main clamp 1 is provided with an upper acupuncture suction cup 6, and the lower main clamp 2 is provided with a lower acupuncture suction cup 7. The upper acupuncture suction cup 6 cooperates with the lower acupuncture suction cup 7.

[0026] As an implementation mode, a lifting cylinder 8 is provided between the upper main clamp 1 and the upper bracket 4 , which is used for the lifting and lowering micro-movement of the upper main clamp 1 .

[0027] As an implementation mode, a buffer 9 is provided between the upper main clamp 1 and the upper bracket 4 to provide a buffering and shock absorbing effect during the lifting process.

[0028] As an implementation mode, a lifting position fine-tuning bolt 10 is provided between the upper main clamp 1 and the upper bracket 4 , which can fine-tune the lifting position of the upper main clamp 1 .

[0029] As an implementation mode, the upper main clamp 1 is connected to the upper acupuncture suction cup 6 via an upper slide rail 11 .

[0030] As an implementation mode, the lower main clamp 2 is connected to the lower acupuncture suction cup 7 via the lower lower rail 12 , and the lower lower rail 12 is connected to the lower clamp 2 via the cylinder 13 , thereby realizing the independent lifting and lowering of the lower acupuncture suction cup 7 .

[0031] As an implementation mode, a linear bearing 14 is provided between the lower sliding rail 12 and the lower main clamp 2 to guide the lifting.

[0032] As an implementation manner, a finger cylinder 15 is provided on the lower slide rail 12 for fastening and locking the slide rail after positioning.

[0033] As an implementation manner, a suction cup 16 is provided on the lower slide rail 12 for positioning the upper sheet after placement.

[0034] The present invention provides a main clamp structure for 3D sewing of car seat sheets, and its working principle is as follows: the upper and lower sheets are gradually placed on the lower main clamp 2, the needling cylinder of the lower needling suction cup extends, and the needling is obliquely inserted into the sponge body of the lower sheet to lock the sheet, and the upper sheet is simultaneously placed on the rear of the lower sheet, and the suction cup 16 sucks the upper sheet to lock it; the upper main clamp 1 moves to the rear side just above the lower main clamp 2, the lifting cylinder 8 of the upper main clamp 1 extends, the upper main clamp 1 descends, the needling of the upper needling suction cup 6 of the upper main clamp 1 extends, and the needling is obliquely inserted into the sponge body of the lower sheet to lock the sheet, and the suction cup 16 sucks the upper sheet to lock it. The plate 16 releases the vacuum pressure, the lifting cylinder 8 of the upper main clamp 1 retracts, and the upper main clamp 1 is lifted into place to complete the grabbing of the upper and lower sheets; during the sewing process, the cylinders of the needle sucker of the sewn sheet are released one by one to release the locking state, effectively solving the distortion and tearing of the sheet caused by different trajectories. The cylinder of the needle sucker is closed and lowered after the needle is pierced, which can better solve the interference of the sewn sheet to the unsewn parts during the sewing process. For sheets of different shapes, the position of the slide rail is adjusted in turn according to the sewing edge of the sheet, and the finger cylinder 15 is locked. The overall structural design ensures the sewing process and has stronger compatibility.
