[0024] Please refer to Figures 1-4In the present embodiment, the upper end surface of the connecting plate 2 is provided with an auxiliary clamping oil passage hole 22, which is connected with a plurality of oil cylinders I 13 through high-pressure hoses. When auxiliary clamping is needed, the hydraulic pump station supplies oil to the auxiliary clamping oil passage hole 22, and the oil is transmitted to each oil cylinder I 13 through the high-pressure hoses, so that they act synchronously to drive the movable pressing plate 14 to press the workpiece. During the whole process, the hydraulic pressure is maintained at a certain value to ensure that the workpiece is always in a stable state. Especially in the case where the main clamping force is not enough to completely fix the workpiece with a complex shape, the upper end surface of the connecting plate 2 is provided with an auxiliary oil release hole 23, which is connected with a plurality of oil cylinders I 13 through high-pressure hoses. When the workpiece needs to be released, the external controller issues an instruction to make the hydraulic oil flow back from the oil cylinder I 13 to the auxiliary oil release hole 23 through the high-pressure hoses, so that the piston rod retracts, and the movable pressing plate 14 is released. During the releasing process, the hydraulic oil in the oil cylinder I 13 is completely discharged to ensure that the movable pressing plate 14 completely leaves the surface of the workpiece.

A workpiece body 5 is installed between the two side supporting nails 7 and the two movable pressing nails 15. A pneumatic sensing module is installed on the surface of the mounting seat 6 near the workpiece body 5. The upper end surface of the connecting plate 2 is provided with a gas detection hole 21, which is connected with the pneumatic sensing module through an air pipe. After the workpiece body 5 is placed in position, the external controller issues an instruction to make compressed air enter the pneumatic sensing module through the gas detection hole 21 and the air pipe. The pneumatic sensing module detects the position and state of the workpiece body 5 by using the pressure change of the compressed air, such as whether it exists and whether it is correctly aligned. After the detection is completed, the pneumatic sensing module feeds back the result to the external controller to confirm whether the workpiece is ready for processing.

[0025] In the process of work, four different workpieces share a set of clamping devices, and the positioning pin seat one 8, the positioning pin seat two 9, the movable pressing plate 14 and the rotary cylinder pressing plate 18 are replaced to complete the clamping of four different workpieces, and the position of the positioning pin seat one 8 and the positioning pin seat two 9 can be changed to adapt to different types of workpieces, so that each workpiece can be accurately placed in the same position. In order to adapt to different types and sizes of workpieces, the clamping mode can be changed by replacing or adjusting the movable pressing plate 14 and the rotary cylinder pressing plate 18. Through simple component replacement and adjustment, the needs of four different workpieces can be met. The clamping body 1 is the basic structure of the whole clamping device, which bears and integrates all other components. The fixed plate 3 provides additional support and stability, enhances the rigidity of the whole clamping device, and firmly fixes the connecting plate 2 on the clamping body 1. The main clamping oil way hole 4 is used to drive multiple oil cylinders two 17 to perform the main clamping action of the workpiece. When hydraulic oil enters the oil cylinder two 17 through the high-pressure hose, the piston rod extends, and then drives the rotary cylinder pressing plate 18 to move, realizing the main clamping action of the workpiece. When the workpiece needs to be loosened, the external controller issues an instruction to make the hydraulic oil flow back to the loosening oil way hole 20 from the oil cylinder two 17 through the high-pressure hose, and the piston rod retracts, and the rotary cylinder pressing plate 18 is loosened. In the loosening process, the hydraulic oil in the oil cylinder two 17 is completely emptied, ensuring that the rotary cylinder pressing plate 18 completely leaves the surface of the workpiece. When auxiliary clamping is needed, the hydraulic pump station supplies oil to the auxiliary clamping oil way hole 22, and the oil is transmitted to each oil cylinder one 13 through the high-pressure hose, so that they act synchronously to drive the movable pressing plate 14 to press the workpiece. In the whole process, the hydraulic pressure is maintained at a certain pressure to ensure that the workpiece is always in a stable state. Especially in the case where the main clamping force is not enough to completely fix the complex-shaped workpiece, when the workpiece needs to be loosened, the external controller issues an instruction to make the hydraulic oil flow back to the auxiliary loosening oil way hole 23 from the oil cylinder one 13 through the high-pressure hose, and the piston rod retracts, and the movable pressing plate 14 is loosened. In the loosening process, the hydraulic oil in the oil cylinder one 13 is completely emptied, ensuring that the movable pressing plate 14 completely leaves the surface of the workpiece. The horizontally placed oil cylinder one 13 pushes the connecting block 12, drives the movable pressing plate 14 and the movable pressing nail 15 to clamp and position, so that the transmission mechanism of horizontal clamping and positioning operates. When the workpiece body 5 is placed in place, the external controller issues an instruction to make compressed air enter the pneumatic sensing module through the air detection hole 21 and the air pipe. The pneumatic sensing module uses the pressure change of compressed air to detect the position and state of the workpiece body 5, such as whether it exists and whether it is correctly aligned. After the detection is completed, the pneumatic sensing module feeds back the result to the external controller to confirm whether the workpiece is ready for processing.

[0026] Through the above steps, four different workpieces share a set of fixture device, by replacing the positioning pin seat 8, positioning pin seat 9, movable pressing plate 14 and rotating cylinder pressing plate 18, a fixture for four different workpieces is completed, by changing the position of the positioning pin seat 8 and the positioning pin seat 9, different types of workpieces can be adapted, and it is ensured that each workpiece can be accurately placed in the same position, in order to adapt to different types and sizes of workpieces, the clamping mode can be changed by replacing or adjusting the movable pressing plate 14 and the rotating cylinder pressing plate 18, through simple component replacement and adjustment, the needs of four different workpieces can be met, so as to solve the problem that the common automobile accessory clamping device cannot adapt to different types of workpieces.
