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. According to the lever principle, the air bag 2 applies external force to the matching part 31, and the pressing part 32 acts on the upper surface of the workpiece to form feeding pressing force. When the air pressure adjusting device is used, the air pressure can be changed through the air supply device at any time to adjust the working pressure of the air pressure adjusting device, the air pressure adjusting device is simple and convenient, labor is saved, and the working efficiency is improved. In addition, the device limits the rotation amount of the pressing block 3 within a certain range, and always provides constant pressing force for the upper surface of a contacted workpiece, so that the stability and the reliability in pressing are improved, and the reason why the device adopts the air bag 2 to provide pressure is that: the air pressure of the air bag 2 is constant through the air supply device, the problem that pressing force changes due to rotation of the pressing block 3 is avoided, and the pressure on a workpiece is kept unchanged during pressing. It is to be noted that: if the pressing force is reduced when the surface of the workpiece is machined, the position of the workpiece cannot be effectively limited, so that the workpiece generates large vibration due to machining, the machining effect of the surface of the workpiece is influenced, the surface of the workpiece is finally unqualified, the rework rate and the rejection rate are improved, and the production cost is greatly improved; on the contrary, if the pressing force becomes large, the smoothness of the movement of the workpiece is affected. Based on the above, therefore, a specific embodiment of the present device is derived.
