Position of the locating part 6 relative to pedestal 1 is adjusted, it is easy to adjust laborsaving.
There is the phenomenon that unexpected loss of excitation in magnetic working table 100 in order to prevent, in some embodiments, is optimized and sets
Meter is provided with magnetic locking device.As shown in Fig. 1, Fig. 1 and Fig. 4, magnetic working table 100 can also include: lock piece 7, locking
Part 7 is switchably located on pedestal 1 between lockup state and unlocked state, and in lockup state, lock piece 7 limits locating part 6
Relative motion occurs between actuating strut 413 or between locating part 6 and actuator 3, avoids 22 unintentional rotation of the second magnetic pole, prevents
There is the phenomenon that unexpected loss of excitation in magnetic working table 100；In unlocked state, lock piece 7 can permit locating part 6 and actuating strut 413
Or relative motion occurs between locating part 6 and actuator 3, it is easy to implement the state switching of magnetic working table 100.
In example as depicted in figs. 1 and 2, lock piece 7 is pivotally arranged in first magnetic pole 21 an of magnetic suction disc 2
On, in the erasing state of Fig. 1 signal, lock piece 7 is located at unlocked state, can permit and occur between locating part 6 and actuating strut 413
Relative motion realizes state switching at this point, actuator 3 can be mobile with drive actions bar 413；And in the magnetisation shape of Fig. 4 signal
State, lock piece 7 turn to lockup state, at this point, lock piece 7 is only butted between actuating strut 413 and the first magnetic pole 21, limitation movement
Bar 413 is mobile relative to locating part 6, so as to which the second magnetic pole 22 is locked at magnetisation position, that is, by magnetic working table 100
It is locked at magnetisation state.
In example as shown in Figure 4, locating part 6 is equipped with the first limit hole, and action piece 421 is equipped with the second limit
Hole, lock piece 7 are configured to lock pin, and lock pin is movably arranged in the first limit hole.In the erasing state of Fig. 4 signal, lock
Stop member 7 is located at unlocked state, and action piece 421 is removable relative to locating part 6, at this point, actuator 3 can be with drive actions part 421
It is mobile, realize state switching；And when the second magnetic pole 22 turns to magnetisation position, the first limit hole and the second limit hole can be just
Right, for lock piece 7 in turn through the first limit hole and the second limit hole, limitation action piece 421 is mobile relative to locating part 6, will
Second magnetic pole 22 is locked at magnetisation position.
As Figure 1-Figure 5, elastic component 23 can be torque spring.That is, the second magnetic pole 22 of each magnetic suction disc 2
The driving force pivoted from magnetisation position to demagnetization position can be provided by the restoring force of torque spring.That is, actuator 3 drives the second magnetic
During pole 22 turns to magnetisation position from demagnetization position, torque spring stores power, multiple after the driving force for discharging actuator 3
Torque spring applies restoring force simultaneously to multiple second magnetic poles 22 respectively under the action of elastic force, makes multiple second magnetic poles 22 simultaneously
Demagnetization position is returned back to, disposable to complete switching, easy switching is laborsaving, high-efficient.
In some embodiments, as shown in Figure 1 and Figure 5, it can be equipped between two adjacent the first magnetic poles 21 every magnetic part 9,
Magnetic field to avoid two adjacent magnetic suction discs 2 interacts, further, two of each first magnetic pole 21 it is extreme between
It can also be equipped with every magnetic part 9, to reduce the probability of magnetic flux leakage generation, so that the magnetic attraction stability of magnetic working table 100 and can
It is further promoted by property.
Advantageously, as Figure 1-Figure 5, each magnetic suction disc 2 can have there are two elastic component 23, to provide enough recoveries
Power meets the second magnetic pole 22 from magnetisation position to power needed for demagnetization position, also, two elastic components 23 are respectively arranged on magnetic force suction
The both ends of disk 2, on the one hand, the both ends stress of the second magnetic pole 22 can be made, uniform force, rotational stability is good, on the other hand, if
Elastic component 23 in end, which can facilitate, to be repaired and safeguards to it, if elastic component 23 damages, can also realize quick-replaceable,
Difficulty is low, high-efficient.
Optionally, actuator 3 can be jack, hydraulic cylinder, electric pushrod or worm and gear component.That is, driving force
It is simple to can be operating mechanism as a result, can throw a sprat to catch a herring, realization is effectively laborsaving, greatly reduces labor intensity, improves effect
Rate.For jack, hydraulic cylinder, electric pushrod and worm and gear component specific structure, it is ripe for those skilled in the art
Know, those skilled in the art can comprehensively consider driving force demand, installation space, cost etc. on the basis of having read above
Therefore, to the type of actuator 3, setting position and connection type etc. carry out adaptability select and set, the present invention to this not
Make specific limit.
In conclusion magnetic working table 100 according to an embodiment of the present invention, by by magnetisation twist machine in the related technology
Structure is focused on a labour-saving force application mechanism by being flexible coupling, the technologies such as jack, electric pushrod, worm and gear for utilizing,
It can throw a sprat to catch a herring, reach good laborsaving purpose, operating mechanism is also very simple.Also, demagnetization utilizes to be pacified on the second magnetic pole 22
The strength that the elastic component 23 of dress is sprung back, it is only necessary to open lock piece 7, the driving force that release actuator 3 applies, multiple second magnetic poles
22 can simultaneously automatic rotary to demagnetization position, demagnetization is disposably completed, and can not only be reduced labor intensity, but also can reduce
The frequency and service working time are operated, shift efficiency is improved.
