Description

Quick-acting overtravel limit switch multiple contact bridge
The present invention relates to one to after a mechanical signal is imported into, will produce simultaneously or the not quick-acting overtravel limit switch multiple contact bridge of changing-over fast simultaneously of 2-10 level.
Extensively adopt travel switch at present in the world, Siemens 3SE3 series is arranged; The terraced adopted XCK of the company series of France; The Japan's W2D of Omron Corp series and China 2 * K3 series all are the products with " quick-acting overtravel limit switch multiple contact bridge " same kind.
The 3SE3 of Siemens production series travel switch is wherein advanced a kind of, and China has introduced production, below just from the have a talk prior art situation of travel switch of the serial travel switch of Siemens 3SE3:
3SE3 series travel switch divides snap-action (being that wink is moving) switch and slow motion (i.e. wriggling) switch two big classes.
1, snap switch: it has a two-sided bridge that touches that silver point is arranged, and is supported on the slide block by two spring supports, has the energy storage effect, by releasing energy suddenly, makes and touches bridge and realize quick changing-over.It has a pair of normally opened contact and a pair of normally-closed contact, according to it the contact logarithm and touch the bridge number, can claim that it is that bridge travel switch (Figure 10) is singly touched in the secondary snap-action.It is not subjected to the influence of actuating speed this switch, even if actuating speed is lower than 0.1 mm/second, the changing-over of switch remains fast (shifting time is not more than 0.04 second), thereby snap switch changing-over time combustion arc duration is short.This travel switch also has: action force is little, repetitive operation precision advantages of higher.
The bridge travel switch is singly touched in the secondary snap-action two big defectives: one be switch contact changing-over kind very little, have only this a kind of; One is the normally open contact and the normally closed interlock distance too near (or claiming to open apart from little) of switch, generally can only be used on the circuit of identical polar.Because the snap-action travel switch has top defective, be stranded this and make the scope of application of switch be subjected to bigger restriction.
What 3SE3 slow motion switch its contact changing-over kind had a secondary also have three grades, have singly to touch bridge, and two bridges that touch are also arranged; Have and open distance for a short time, also have large opening or the like.The slow motion travel switch of large opening can be used for the circuit of opposed polarity.The kind that has can realize that time-delay disconnects the function of (promptly intersecting).
3SE3 slow motion travel switch has a very big shortcoming, touch bridge exactly and do not have energy storage mechanism, actuating speed is exactly the changing-over speed that the trip switch touches bridge, thereby actuating speed to touch the speed of bridge changing-over when low also low thereupon, cause contact changing-over combustion arc duration long, influence the useful life of whole travel switch, if actuating speed is lower than 1 mm/second, changing-over obstacle in contact also can take place, so the slow motion travel switch can not show a candle to snap-action and singly touches the bridge travel switch on electric property.
The objective of the invention is to avoid above-mentioned existing snap-action travel switch weak point, and multiconductor changing-over simultaneously is provided, time-delay is connected and time-delay disconnects three types 2-10 level snap-action travel switch, and the above multiple-pole switch of bridge is touched in snap-action three, can realize the mixing time-delay changing-over of contact.
The objective of the invention is to realize by following design:
By housing (1), push rod (2), slide block (3), touch bridge (4), spring(-supported) mount (5) or reed (11), contact (8), touch bridge (7), quick-acting overtravel limit switch multiple contact bridge that back-moving spring (9), block (6), cover plate (10) constitute, the projection (18) of block (6) is compressed into the groove (19) of housing (1) and the groove (20) of cover plate (10), block (6) is the position that is used for guaranteeing to touch bridge (4), significant feature is to reach the identical travel switch of progression, although contact changing-over kind difference, shell at the same level is general; The slide block (3) of mounting spring frame (5) has 2~9 fulcrum of spring (21), distance between the two adjacent fulcrum of spring (21) equates, or differ ± 0.5~1.5mm, realize changing-over simultaneously, time-delay is connected and time-delay disconnects 2~10 grades of snap-action travel switches of three types, the multiple-pole switch that snap-action three bridges are above is to realize the mixing time-delay changing-over of contact; 2~9 pairs of v-depressions (27) of mutual correspondence are processed in the two sides that the slide block (22) of reed (11) is installed.At the open type travel switch, be that contact (8) is fixed on the cover plate (10) with screw assemblies (12), respectively there is small embossment (23) at cover plate (10) two ends, stick in the cover plate corresponding grooves, the sealed type travel switch, be that lead-in wire (15) directly is welded on the contact (8), lead-in wire (15) is drawn by housing side opening (24) or last hole (25), make the contact pitch compactness like this, be convenient to any arrangement of multiple-pole switch, travel switch total length more than three grades and three grades is reduced, between push rod (2) and the slide block (3) seal closure (16) is housed, at side opening (24) or go up between hole (25) and the lead-in wire (15), with epoxy resin or silicon rubber (26) pouring sealing, cover plate (10) seals with the epoxy resin pouring with housing (1).
Quick-acting overtravel limit switch multiple contact bridge of the present invention has above advantage:
1, to touch the bridge changing-over all be fast, so it has possessed whole advantages that the bridge travel switch is singly touched in the 3SE3 of Siemens Company snap-action.The contact changing-over kind of quick-acting overtravel limit switch multiple contact bridge (two 28 kinds on bridges that touch, three touch 63 kinds on bridge, four touch bridge kind more than 100) is considerably beyond the kind number of Siemens 3SE3 slow motion travel switch (secondary and three grades totally 9 kinds).Quick-acting overtravel limit switch multiple contact bridge can be realized large opening, is used on the circuit of opposed polarity.And the still existing defective shortcoming of slow motion of Siemens 3SE3 series travel switch snap-action is all given to overcome by quick-acting overtravel limit switch multiple contact bridge, thereby we can say that the electric property of quick-acting overtravel limit switch multiple contact bridge has surpassed the level of existing advanced travel switch.
2, Siemens 3SE3 slow motion travel switch has time-delay on-delay break function, but the time that is prolonged is very of short duration.This function is relevant with actuating speed, and actuating speed is slow more, and it is long relatively more to delay time, but actuating speed is slow excessively, and there is harmful effect in life-span of slow motion switch.We calculate by limit actuating speed 1 mm/second of 3SE3 slow motion travel switch defined, and the time-delay of switch is no more than 2 seconds, and at this moment it has been in very bad changing-over state.
The actuating speed of quick-acting overtravel limit switch multiple contact bridge does not influence the quick changing-over of switch.We are by the actuating speed calculation of 0.1 mm/second, the time-delay of switch can reach 15 seconds, calculate by 0.05 mm/second, the switch time-delay can reach 30 seconds, and the switch contact shifting time still is within 0.04 second, thus quick-acting overtravel limit switch multiple contact bridge possessed can be by the delay function of the long period of practical application.
3, quick-acting overtravel limit switch multiple contact bridge has the program control function.For example bridge travel switch (Figure 27) is touched in a Pyatyi snap-action four, and trip map (Figure 28) shows that its changing-over kind belongs to one normally closed four and often starts Cheng Kaiguan, the normally closed disconnection of the first order when 1.5mm is arrived in switch motion, second level closure; The 3rd is extremely closed in the time of 2 millimeters, fourth stage closure in the time of 2.5 millimeters, level V closure in the time of 3 millimeters.If actuating speed is 0.1 mm/second, every grade of action of switch is spaced apart 5 seconds.A quick-acting overtravel limit switch multiple contact bridge so just can carry out program control to lathe.The 3SE3 travel switch will realize that said procedure control then needs five switches.Quick-acting overtravel limit switch multiple contact bridge is all surpassing existing travel switch level on utility function on the kind in sum.
