Detection device of travel switch
Technical field
The utility model relates to mold machining technology field, particularly relates to a kind of pick-up unit that can easy detection travel switch whether can normally work.
Background technology
Whether the mould overwhelming majority meets the requirements of travel switch with the motion for detection of ejector retainner plate and slide block.Mould needs hot flow path and travel switch to mould to detect before die trial after producing.Traditional detection travel switch is the resistance grade test with multimeter, give in addition electric current of tested travel switch with the built-in power of multimeter, and the resistance of current measurement travel switch accordingly, because travel switch is off state when normally not by touch-control, and when touched, approach an off state, embody a very little self-resistance, so need to judge by resistance value when with multimeter test travel switch, if travel switch is disconnected, need to investigate each travel switch erection sequence whether wrong and need to verify which travel switch erection sequence mistake, adjust, detect and then testing with multimeter, also need to adjust again if do not become, this just causes repetitive operation, inefficiency, detect strongly professional and require high to testing staff's specialty, a people is difficult to competent.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of pick-up unit that can easy detection travel switch whether can normally work is provided.
For realizing the technical scheme that the purpose of this utility model adopts be:
A kind of detection device of travel switch, comprise detection box, be fixedly installed on the multiple pilot lamp that detect on box side panel, be arranged on the power supply that detects box inside, and be arranged on described detection box one side panel and the multipair connection terminal corresponding with described pilot lamp, wherein, described pilot lamp one end is communicated with a utmost point of described power supply, and another utmost point of the other end of this pilot lamp and power supply is connected to respectively two paired connection terminals.
Described detection box comprises front cover body and the bonnet being fixedly connected with described front cover body, described pilot lamp is arranged on the leading flank of front cover body, described power supply is fixedly installed on front cover body inside, and described connection terminal is fixedly installed on the electric connection of both sides, cap body front and back on bonnet and after realizing.
Be provided with fixed pin in described front cover body both sides, rotatably be provided with snap fit in described bonnet both sides, described snap fit comprise two parallel interval settings and by bonnet the sealed plate in the middle of being clamped in, the pressing plate that two described sealed plates are fixedly connected with, on described sealed plate, be provided with can be sealed with described fixed pin matchingly latch hook.
On described front cover body or bonnet, be fixedly installed rubber washer, the rubber washer described in when current cover body and bonnet are sealed is clamped between the two.
Compared with prior art, the beneficial effects of the utility model are:
Pick-up unit of the present utility model only needs the two ends of travel switch to access accordingly two paired connection terminals in use, between power supply and pilot lamp, seal in travel switch by connection terminal, when travel switch is not touched, this loop, pilot lamp place disconnects, if touched, this this circuit closed pilot lamp is bright, straightforward by the bright no judgement of pilot lamp, left-hand seat easily, simultaneously in the time having malfunction elimination problem, because travel switch is connected in the loop of pilot lamp always, viewing lamp state easily in investigation problem, without back and forth between travel switch and checkout equipment, improve investigation efficiency.

Figure 1 shows that structural representation of the present utility model;
Figure 2 shows that the internal circuit configuration schematic diagram of stroke closing detecting apparatus of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, 2, detection device of travel switch of the present utility model comprises detection box, be fixedly installed on the multiple pilot lamp 1 that detect on box leading flank, be fixedly installed on the power supply 2 that detects box inside, and be arranged on described detection box afterbody and the multipair connection terminal corresponding with described pilot lamp, wherein, every pair of wire connection terminals is two, and it is corresponding with a pilot lamp and a travel switch to be connected respectively.Described pilot lamp one end is communicated with a utmost point of described power supply, and another utmost point of the other end of described pilot lamp and power supply is connected to respectively two paired connection terminals 9.Specifically, described detection box comprises front cover body 3 and the bonnet 4 being fixedly connected with described front cover body, described pilot lamp is arranged on the leading flank of front cover body, described power supply is fixedly installed on front cover body inside, and described connection terminal is fixedly installed on bonnet and realizes the electric connection of both sides.It should be noted that, power supply generally can adopt dry cell or accumulator, for avoiding power supply to rock in front cover body, also can in described front cover body, the structures such as battery compartment be set, meanwhile, described connection terminal can be selected commercially available multiple connection terminal, enables with inner and is connected with battery and pilot lamp, outside and each travel switch is connected, and does not repeat them here its structure.
Pick-up unit of the present utility model only needs the two ends of travel switch to access accordingly two paired connection terminals in use, between power supply and pilot lamp, seal in travel switch by connection terminal, when travel switch is not touched, this loop, pilot lamp place disconnects, if touched, this this circuit closed pilot lamp is bright, straightforward by the bright no judgement of pilot lamp, left-hand seat easily, simultaneously in the time having malfunction elimination problem, because travel switch is connected in the loop of pilot lamp always, viewing lamp state easily in investigation problem, without back and forth between travel switch and checkout equipment, improve investigation efficiency.
Further, for improving the sealing that detects box, also be convenient to dismounting and change battery simultaneously, be provided with fixed pin 8 in described front cover body both sides, rotatably be provided with snap fit in described bonnet both sides, described snap fit comprises two parallel interval settings and bonnet is clamped in to middle sealed plate 6, the pressing plate 9 that two described sealed plates are fixedly connected with, on sealed plate, be provided with can be sealed with described fixed pin matchingly latch hook 7, simultaneously, on front cover body or bonnet, be also fixedly installed rubber washer 5, rubber washer described in when current cover body and bonnet are sealed is clamped between the two.Rotation snap fit can be realized locking or the release of latch hook and fixed pin, can easily front cover body be locked or be separated with bonnet like this, whole process can not form and disturb interconnector, be clamped in rubber washer between the two simultaneously, make the locking and unlocking process strengthen more easily the sealing that both connect simultaneously.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
