A plurality of pressing blocks 3 capable of rotating independently are arranged on the transverse shaft 13, gaps are reserved between every two adjacent pressing blocks 3, and the problem that the rotation of the pressing blocks 3 is influenced or the pressing blocks are blocked due to contact friction between every two adjacent pressing blocks 3 is solved through the gaps; in a preferred embodiment, the gap between adjacent compacts 3 is 0.15-1.0mm, such as 0.20mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, 0.85mm, 0.9mm, 0.95mm, etc.
In the device, a position-adjustable limiting rod 111 is arranged at the corresponding position of the fixing plate 11 and each pressing block 3, and a limiting frame 14 is formed between each limiting rod 111 and the air bag 2. The pressing block 3 comprises an upper matching part 31 and a lower pressing part 32, when the pressing block is assembled, the middle position of the pressing block 3 is matched with the transverse shaft 13, the matching part 31 is upwards positioned in the limiting frame 14, and the pressing part 32 extends towards the oblique lower part of one side of the fixing plate 11. When the device is used, the initial position of the pressing block 3 is determined through the limiting frame 14, and the method specifically comprises the following steps: after the airbag 2 is inflated, the position of the limiting rod 111 on the fixing plate 11 is adjusted, and then the width of the limiting frame 14 (i.e. the distance between the end of the limiting rod close to the airbag side and the airbag) is adjusted, so that the initial position of the matching part 31 of the pressing block 3 in the limiting frame 14 can be determined, and the position of the pressing block 3 is determined. In addition, the size becomes when gasbag 2 inflates and expands to can promote cooperation portion 31 removes (briquetting rotates as a whole), controls gasbag 2 air feed pressure through air feeder, adjusts the atmospheric pressure and the inflation volume of gasbag 2, and then the regulation is right the size of briquetting 3 holding power just also can play the pressure size of adjusting briquetting 3 to the work piece production. When a workpiece contacts the pressing part 32, referring to fig. 4, the pressing block 3 is subjected to an external force F from bottom to top, so that the pressing block 3 can be driven to rotate around the transverse shaft 13, and during the rotation, the matching part 31 generates pressure on the airbag 2 to enable the airbag 2 to generate certain deformation (referring to fig. 4), but the position of the limiting rod 111 is always unchanged, so that the pressing block 3 can only rotate to the side where the airbag 2 is located in the initial state; when the external force disappears, the air bag 2 pushes the pressing block 3 to reset.
The structure principle and the technical effect of the device are as follows: after the air bag 2 is inflated, the air bag 2 provides the same pressure for all the pressing blocks 3, and the pressure is constant without independent adjustment.
