The spring bladder 754 then expands, further increasing the holding force, increasing the holding force on the two end surfaces of the bearing, thereby greatly increasing the holding effect on the bearing.
More specifically, a relief valve 78 is disposed in the second control chamber, and when the pressure in the second control chamber is too high, the pressure is relieved outwards through the relief valve 78.
Specifically, the clamping member 7 further includes: a connection member 77, a connection rod 771, an annular plate 772. The annular plate 772 is fixedly connected with the clamping tube 71, the connecting rod 771 is fixedly connected with the annular plate 772, the connecting member 77 is fixedly connected with the annular plate 772, and the connecting member 77 is fixedly connected with the first hinging block 4.
The working flow is as follows:
when the bearing is used, the bearing is firstly placed on the third supporting plate 21, then the first driving air cylinder 51 controls the transmission plate 52 to move downwards, the second hinging block 53 moves downwards, the first hinging block 4 is driven by the first hinging block 4 to move through the fastener 6, the first hinging block 4 moves near the axle center of the supporting piece 2 under the guidance of the multi-section telescopic guide rod 55, and the first hinging block 4 drives the clamping pipe 71 to move near the axle center of the supporting piece 2 together through the connecting component 77, so that the lateral abutting of the clamping pipe 71 and the bearing is realized. Then the second driving cylinder 61 drives the fastener 6 support 2 to move upwards, the fastener 6 support 2 is in contact with the transmission connecting rod 54, and then the fastener 6 support 2 enables the transmission connecting rod 54 to be acted on by force, so that the effect that the first hinging block 4 is acted on by force close to a bearing, and the side face of the bearing is clamped tightly is achieved.
The clamping tube 71 approaches the side of the bearing until abutting the side of the bearing, so that the air tap 73 abuts the side of the bearing, then the outside of the spray head 733 is subjected to an external force, the spray head 733 moves close to the fixing rod 731, the fixing rod 731 is fixed, so that the sealing plate 732 is stationary relative to the fixing rod 731, the spray head 733 moves close to the fixing rod 731, which corresponds to the movement of the sealing plate 732 away from the end face of the second air cavity, so that the through groove at the second air cavity is opened, and then the first air cavity is communicated with the accommodating cavity through the second air cavity and the through groove. After the end face of the second air cavity in the nozzle 733 abuts against the sealing plate 732, the nozzle 733 is limited by the sealing plate 732, so that the nozzle 733 cannot move away from the fixing rod 731 under the action of the spring 734, the nozzle 733 is in the first state, and at the moment, the nozzle 733 is partially located outside the clamping tube 71. When the clamp pipe 71 contacts the side of the bearing, the nozzle 733 is pressed against the side of the bearing, and the nozzle 733 moves to a position where the second state of the nozzle 733 is located under the action of the pressure. The pressure relief valve 78 then brings the receiving chamber to a negative pressure, so that the holding tube 71 adsorbs the side of the bearing by the negative pressure, and a further fixation of the bearing is achieved.
The air pump 764 is used for sucking air in the first control chamber into the second control chamber through the fourth air pipe 763, the arc-shaped air pipe 762 and the third air pipe 761, and then the first control chamber becomes negative pressure, so that the air tap 73 can adsorb the side of the bearing, then the first control chamber becomes negative pressure, the two piston plates 74 can be close to each other, then the air in the first control chamber reaches the second control chamber, the pressure in the second control chamber is increased, the speed of the two piston plates 74 moving towards each other is increased, and then the pressure cannot be reduced until the negative pressure in the first control chamber reaches the limit. In this process, the pressure of the second control chamber increases, so that the air of the second control chamber reaches the first driving cylinder 51 of the holder 7 through the communication port 752, then reaches the second air tube 753, and then reaches the elastic air bag 754, and the elastic air bag 754 is inflated. Since the two piston plates 74 move the two first driving cylinders 51 of the clamping member 7 toward each other, the fixing blocks 755 on the first driving cylinders 51 of the clamping member 7 move together with the first driving cylinders 51 of the clamping member 7, and the pressing plates 756 on the fixing blocks 755 abut against the end surfaces of the bearings, thereby clamping the end surfaces of the bearings. The spring bladder 754 then expands, further increasing the holding force, increasing the holding force on the two end surfaces of the bearing, thereby greatly increasing the holding effect on the bearing.
