The working principle and the using method are as follows:
presetting:
the upper part of the adjustable pressing seat 402 is adjusted according to the shape of the workpiece, and parts with different specifications are installed through the positioning pin holes.
The sensing position-limiting strip 602 is adjusted to a proper position (generally, the maximum stroke end of the movable carrier plate) by adjusting the screw rod three.
And (4) carrying out no-load test operation on the equipment, adjusting the position of the detection block 604 according to the shape of the workpiece, and adjusting the position of the movable end on the clamping base.
The work is as follows:
the workpiece to be assembled is placed on a movable support plate (generally a cuboid plastic plate, and a corresponding fixing groove is formed in the cuboid plastic plate).
The bearing to be assembled is placed on the adjusting clamping base, and the electromagnet adsorbs the bearing to be assembled, so that the position of the bearing to be assembled is ensured not to deviate.
The movable carrier plate is placed on the second roller shaft 502, the distance sensor outputs signals to the microprocessor, the microprocessor outputs signals to the second servo motor, the second servo motor is started to drive the movable carrier plate to a preset position, the distance sensor outputs signals to the microprocessor again, the microprocessor outputs signals to the first push rod motor 504, the first push rod motor 504 is started to enable the weighing panel 505 to move upwards, the roller 506 is higher than the first roller shaft 501 and the second roller shaft 502, the microprocessor outputs signals to the starting devices of the power oil cylinder 401 and the power air cylinder 301 in a delayed mode, and the power oil cylinder 401 and the power air cylinder 301 start a pressing process.
After the pressing procedure is completed, the power oil cylinder 401 and the power air cylinder 301 are reset, the microprocessor outputs a signal to the first servo motor, and the first servo motor is started, so that the assembled workpiece leaves.
In this process, the ram 401 is often operated over distance due to the complexity of the workpiece and the association with other components, as shown in fig. 11. At this time, if the power cylinder 301 is still operated in the extended state, since the thrust of the power cylinder 401 is several tens times that of the power cylinder 301, the piston of the power cylinder 301 is forcibly retracted, resulting in cylinder burst damage.
In the invention, when the power cylinder 401 runs at an over-distance, the infrared obstacle avoidance sensor outputs a signal to the microprocessor, the microprocessor outputs a signal to the cylinder protection system, the two-position five-way solenoid valve I101 is electrified, the two-position five-way solenoid valve II 102 is powered off, and the power cylinder 301 enters a third working condition.
The gas enters the atmosphere from the A gas outlet pipe 1015 of the first two-position five-way electromagnetic valve to the second A gas outlet pipe 1025 of the second two-position five-way electromagnetic valve (the air pump does not need to be closed, the time is saved, and the service life of the air pump is prolonged).
And the gas on one side of the piston flows out from the gas outlet pipe 1024 of the two-position five-way electromagnetic valve II B to the gas outlet pipe 1022 of the two-position five-way electromagnetic valve II 01.
Gas on the other side of the piston flows out from the gas outlet pipe 1015 of the two-position five-way electromagnetic valve A to the gas outlet pipe 1013 of the two-position five-way electromagnetic valve 02.
The air at the two ends of the piston is in an open state, the piston can be rapidly decompressed, the power cylinder 301 cannot be damaged under the force applied by the power oil cylinder 401, the cylinder explosion probability is obviously reduced, and the service life of the cylinder is prolonged.
In addition, when the oil cylinder 701 exceeds the specified stroke (or reaches the maximum specified stroke), the power cylinder immediately enters a third working condition (namely, the protection system is regulated and controlled according to software and an oil cylinder operation rule). And converting into a free working state. Therefore, complex control programs such as various sensors, PLC and the like can be saved.
The cost is obviously reduced, and the cylinder explosion probability can be further reduced by matching the two methods.
Example 3 referring to fig. 12-13, under the control of a two-position five-way solenoid valve, if a common cylinder rod is electrified, the common cylinder rod is retracted after the electrification, and vice versa, and two working states, namely the extended state and the retracted state, the common cylinder rod is in a stressed state, as shown in fig. 12.
In FIG. 12, A, B represents the inlet and outlet of a conventional cylinder I802 or two-position five-way solenoid valve III 801, and if A is the inlet, B is the outlet; if A is the air outlet, B is the air inlet. P is the compressed air inlet and O1 and O2 are the exhaust, typically leading to the atmosphere through the muffler.
The left side of the figure 12 shows the three 801 power-off states of the two-position five-way electromagnetic valve, and P-A and B-O1 are communicated respectively; P-B and A-O2 were blocked separately. The right side of FIG. 12 is the three 801 energized state of the two-position, five-way solenoid valve with P-A and B-O1 blocked respectively; P-B and A-O2 are on, respectively.
The protection system suitable for the cylinder comprises the two-position five-way electromagnetic valve and the common cylinder, wherein the two-position five-way electromagnetic valves are adopted to control the common cylinder, so that the common cylinder can be in a free state without stress except for the two stressed working states. The unstressed free state means that two air ports A and B of a common cylinder are communicated with the atmosphere, and a piston of the common cylinder cannot be acted by a compressed air source.
Under the working condition, in the stroke of the common cylinder, the common cylinder rod is subjected to huge reverse acting force, and the common cylinder and the air circuit element cannot be damaged.
The invention is used for absorbing the reverse displacement caused by the unbalance of the two oil cylinders, and is more convenient, more economical and safer compared with the traditional servo control system.
The structural principle of the invention is shown in fig. 13, and fig. 13 is also an innovative point of the patent.
A two-position five-way electromagnetic valve A901 and a two-position five-way electromagnetic valve B902 are adopted to control a common air cylinder II 903. The port A of the two-position five-way electromagnetic valve A901 is closed by a choke, and the port B and the port P of the two-position five-way electromagnetic valve A901 are communicated with the port B of the common cylinder II 903 and the port B of the two-position five-way electromagnetic valve B902 respectively; the port of the two-position five-way electromagnetic valve B902A is connected with the port of a second common air cylinder 903A, and the port of the two-position five-way electromagnetic valve B902P is connected with a compressed air source (such as an air pump).
As shown in fig. 13, three operating states of the normal cylinder two 903 can be realized by controlling the energization states of the two-position five-way solenoid valve a 901 and the two-position five-way solenoid valve b 902, respectively. Fig. 13 shows the extended state on the left, the free state in fig. 13, and the retracted state on the right in fig. 13.
An A port of a second common cylinder 903 in a free state, A-A-O2-atmosphere; port B, B-O1-atmosphere, compressed air source is blocked at port a of two-position five-way solenoid valve a 901. The piston of the second ordinary cylinder 903 is not subjected to the acting force of the compressed air source.
