TECHNICAL FIELD

[0001] The utility model relates to the field of industrial equipment, especially a piston assembly of diaphragm. BACKGROUND

[0002] In many fields such as industrial production, chemical conveying, medical equipment, the piston assembly of diaphragm as a key component plays a decisive role in the stable operation and performance of the system.

[0003] In the hydraulic drive mechanical manufacturing equipment, if the traditional single-piston diaphragm piston assembly is used, only different parts of the workpiece can be pressed one by one, which not only leads to uneven force on the workpiece, affecting the processing quality, but also greatly prolongs the processing time and reduces the production efficiency; driving two pistons to work can significantly improve the working efficiency and precision of the equipment. For example, in a large hydraulic machine, in order to realize uniform pressure on a large workpiece, two pistons often need to act simultaneously. Based on this, we propose a piston assembly of diaphragm. SUMMARY

[0006] The motor is stably installed on the fixed seat, which provides power source for the whole assembly. The rotary rod is sleeved with the fixed sleeve, which is fixed on the fixed seat and limits the rotary rod to ensure its stability during rotation. One end of the rotary rod is fixedly connected with the output shaft of the motor, and when the motor starts, the output shaft drives the rotary rod to rotate. The other end of the rotary rod is rotatably connected with one end of the deflection shaft rod, so that the rotary motion of the motor is smoothly transmitted to the deflection shaft rod.

[0007] The other end of the deflection shaft rod is connected with the movement shaft center, which also performs circular motion with the rotation of the deflection shaft rod. The outer side of the movement shaft center is connected with one end of the guide rod, which plays a key role in transmitting motion and guiding. It transmits the circular motion of the movement shaft center to the connecting shaft center frame, so that the connecting shaft center frame moves along a specific trajectory.

[0008] The bottom end of the connecting shaft frame is connected with one end of the connecting block, and the other end of the connecting block is connected with the movable shaft block.

[0009] The inner side of the groove frame plate is slidably connected with the piston rod, and the piston rod is connected with the connecting shaft frame.

[0010] After the motor is started, the output shaft drives the rotating rod to rotate, the rotating rod drives the deflection shaft rod to move through the deflection shaft, the movement axis on the deflection shaft rod makes a circular motion, and the movement is transmitted to the connecting shaft frame through the guide rod, the connecting shaft frame drives the connecting block and the movable shaft block to move, the movable shaft block slides in the movable clamping groove, and the deflection shaft frame plate slides on the groove frame plate, so that the piston rod and the piston head make reciprocating motion in the diaphragm pump cavity, and relevant functions are realized.

[0011] As a further improvement of the utility model, the top end of the piston rod is fixedly connected with the piston head, and the piston head is located in the diaphragm pump cavity.

[0012] As a further improvement of the utility model, when the connecting shaft frame moves, the movable shaft block slides in the movable clamping groove, and the deflection shaft frame plate slides on the inner side of the groove frame plate through the slider on the bottom surface thereof.

[0013] As a further improvement of the utility model, the piston rod is provided with two groups, and the two groups of piston rods are connected with the connecting shaft frame, so that the assembly can drive two piston heads to work simultaneously.

[0014] As a further improvement of the utility model, the two groups of connecting blocks drive the two groups of movable shaft blocks to slide in the two groups of movable clamping grooves respectively, and the deflection shaft frame plate slides on the inner side of the groove frame plate through the slider on the bottom surface thereof, thereby driving the two groups of piston rods to make reciprocating linear motion.

[0015] As a further improvement of the utility model, the two groups of piston heads work simultaneously to realize more uniform pressure on large workpieces, and the working efficiency and precision of the equipment can be significantly improved.

[0016] Compared with the prior art, the utility model has the beneficial effects that:

[0017] 1、The utility model discloses two groups of movable clamping slots cooperate with movable axle blocks, and the slider connecting structure of deflection axle frame plate and groove frame plate, effectively enhance motion guide and constraint.

These structures cooperate with each other to further accurately guide and effectively constrain the motion, ensuring the accuracy and stability of the whole motion process.

[0029] The inner side of the slot frame plate 14 is slidably connected with the piston rod 15, and the piston rod 15 is connected with the connecting shaft frame 9.

[0030] Specific technical solutions, when the motor 2 is started, the output shaft drives the rotating rod 3 to rotate, the rotating rod 3 drives the deflection shaft 5 to move through the deflection shaft 6, the motion shaft 7 on the deflection shaft 5 performs circular motion, which is transmitted to the connecting shaft frame 9 through the guide rod 8, the connecting shaft frame 9 drives the connecting block 10 and the movable shaft block 11 to move, the movable shaft block 11 slides in the movable clamping groove 12, and the deflection shaft frame plate 13 slides on the slot frame plate 14, finally driving the piston rod 15 and the piston head 16 to reciprocate in the diaphragm pump cavity 17, realizing the related functions.

The two sets of piston rods 15 are provided, and the two sets of piston rods 15 are connected with the connecting shaft frames 9, so that the assembly can drive two piston heads 16 to work at the same time. The deflection shaft frames 13 are arranged in an inclined manner on the surface of the groove frame plate 14, and the inclined design is helpful to optimize the force transmission and movement coordination.

[0032] The two sets of connecting blocks 10 drive the two sets of movable shaft blocks 11 to slide in the two sets of movable clamping grooves 12 respectively, and the deflection shaft frame plate 13 slides in the groove frame plate 14 through the bottom sliding block, and simultaneously drives the two sets of piston rods 15 to do reciprocating linear motion.

[0034] The overall working principle of the patent technical solution is as follows:

[0035] Power input and preliminary transmission: the motor 2 is fixedly installed on the fixed seat 1, and after starting, the output shaft of the motor 2 drives the rotating rod 3 to rotate. The fixed sleeve 4 sleeved on the surface of the rotating rod 3 plays a limiting role, so as to ensure the stable rotation of the rotating rod 3. One end of the rotating rod 3 is fixedly connected with the output shaft of the motor 2, and the other end is rotatably connected with one end of the deflection shaft 5 through the deflection shaft 6, so that the rotary motion of the motor 2 is transmitted to the deflection shaft 5.

[0036] Motion conversion and transmission: the other end of the deflection shaft 5 is connected with the motion shaft 7, and the motion shaft 7 also does circular motion with the rotation of the deflection shaft 5. One end of the guide rod 8 connected with the outside of the motion shaft 7, and the circular motion of the motion shaft 7 is transmitted to the connecting shaft frame 9 through the guide rod 8. The guide rod 8 plays a role in transmitting motion and guiding in this process, so that the connecting shaft frame 9 moves along a specific trajectory.
