Description
Technical field
The utility model relates to isolating switch detection field, and more particularly it relates to a kind of handle operation mechanism of miniature circuit breaker checkout equipment.
Background technology
Isolating switch usually all needs to carry out properties detection to it after production and processing completes, wherein one is the on off test of isolating switch, usually by isolating switch being fixed on fixing fixture in automatic detection system, the connection terminal at the two ends of isolating switch is electrically connected with the detecting unit for detecting break-make, again by the break-make of stirring handle control isolating switch of stirring on isolating switch back and forth, when handle stir be in ON state time, the connection terminal at isolating switch two ends requires to be in conducting state, when handle stir be in OFF state time, require that the connection terminal at isolating switch two ends is in off-state, if any one there is mistake in both, then this isolating switch break-make detects defective.
Authorization Notice No. is that the Chinese patent of CN201637824 U discloses a kind of delivery life test device of plastic case circuit breaker, comprise worktable, it is characterized in that, described worktable is provided with test board, isolating switch to be detected is placed in test, this worktable is provided with for clamping isolating switch to be detected to make its fixing locating device simultaneously, for promoting circuit breaker operation mechanism to make the closing device of breaker closing to be detected, for separating brake/buckle device and the trip gear for realizing circuit breaker tripping to be detected again promoting breaker open operation to be detected or detain again, described locating device, closing device, the start/stop of buckle device and trip gear of separating brake/is again controlled by controller.According to its instructions and accompanying drawing, its combined floodgate separating brake all promotes operating grip by cylinder and realizes.But for the miniature circuit breaker that market generally uses, there is certain defect in this testing agency, because the operating grip of miniature circuit breaker is all shorter and smaller, when being fixed on test board, the piston rod of cylinder is not easy to promote operation to it, and the impetus that cylinder does is rectilinear motion, and the operating grip of miniature circuit breaker is initially and tilts to certain angle, cylinder promotes to produce an acting force towards operator arbor portion to operating grip in operating grip process, because operating grip is shorter, the position of its axle portion and handle and cylinder contact is more close, therefore the percussive action be subject to is larger, the each link be easily connected with operating grip miniature circuit breaker inside causes damage, thus the quality of product is impacted, the testing goal of expection cannot be reached.
Utility model content
For the deficiency that prior art exists; the purpose of this utility model is to provide a kind of miniature circuit breaker checkout equipment handle operation mechanism; its more convenient handle to miniature circuit breaker in testing process carries out make-break operation; and to the operating mechanism of miniature circuit breaker, there is better protectiveness, effectively improve the quality of products.
For achieving the above object, the utility model provides following technical scheme: a kind of handle operation mechanism of miniature circuit breaker checkout equipment, comprise test board, described test board is provided with the posting for clamping isolating switch, described posting is provided with the lengthening handle with circuit breaker operating handle coaxial linkage, described test board is provided with the driving cylinder for operating lengthening handle, described driving cylinder is provided with the piston rod extending cylinder body, connecting rod is provided with between the other end in described lengthening handle its axle portion relative and piston rod, one end and the lengthening handle of described connecting rod are hinged, the other end and piston rod hinged, described test station is when horizontality, piston rod is positioned at the top of lengthening handle.
By adopting technique scheme, when isolating switch is carried out break-make or is detected mechanical life, miniature circuit breaker is fixed on the posting internal fixtion on test board, the operating grip of miniature circuit breaker is and is articulated with in housing, housing is extended for operation by human hand in one end, lengthening handle on posting can with the operating grip coaxial linkage of this isolating switch, make both motion processes consistent, and effectively increase the length of the handle that original isolating switch moves for confession checkout equipment, be more convenient for operation and detect, handle is all positioned at the end place of handle by the place moved, the increase of decreased food, effectively increase the distance between this stressed place and circuit breaker operating handle axle portion, the percussive action that moves be subject to is reduced, better protective effect is played to the operating mechanism of isolating switch.Also abandoned drove piston rod directly to promote the mode of circuit breaker operating handle with cylinder simultaneously in the past, because operating grip is hinged state, its movement locus is a cambered surface, therefore the loading angle of its best is also that the arc of its movement locus adjoint is to acting force, in the past during cylinder linear pushing operating grip, power can cause greater impact to the operating mechanism of isolating switch in the housing of isolating switch greatly, easily causes operating mechanism to damage.This programme arranges a connecting rod by hinged between lengthening handle end and the piston rod of driving cylinder, connecting rod and piston rod, articulated structure is between lengthening handle, when driving air cylinder driven piston rod to do rectilinear motion, piston rod pulls connecting rod, connecting rod pulls lengthening handle again, because piston rod is placed in the upper end of lengthening handle, therefore now first lengthening handle is subject to a pulling force obliquely, and this pulling force is all the time with the angle change that lengthening handle moves, reach the mode that a simulation staff moves, staff moves power used be namely an arc to acting force, thus avoid cylinder and move impact to circuit breaker operation mechanism in the process of operating grip, better protective effect is played to the isolating switch in detecting, improve the quality of products.
The utility model is set to further: described lengthening handle is that inverted T-shaped structure includes vertical portion and lateral part, the top of described vertical portion and rod hinge connection, described lateral part is connected with the operating grip of isolating switch, two ends and the posting of described lateral part are hinged, and its hinged place is on the extended line of the axis of circuit breaker operating handle.
By adopting technique scheme, the structure of lengthening handle and isolating switch coaxial linkage is further described, this lengthening handle is for being inverted T-shaped structure, the top of vertical portion and rod hinge connection, lateral part is connected with the operating grip of isolating switch and reaches interlock effect, and isolating switch is in fixing and posting, the extended line of the axis of its operating grip inherently has overlapping position with the framework of posting, the two ends of lengthening handle lateral part are just articulated with this place, thus make the axis of lengthening handle and the dead in line of circuit breaker operating handle, reach the effect of a coaxial linkage, coaxial linkage makes lengthening handle reach consistent with the motion process of the operating grip of isolating switch, be more convenient for detecting, and it is stressed more balanced, be more conducive to moving of operating grip.
The utility model is set to further: the side of the relative test board in described lateral part is provided with the draw-in groove for inlay card circuit breaker operating handle.
By adopting technique scheme, the connected mode of lengthening handle and circuit breaker operating handle is further described, by the side of test board relative to lateral part, draw-in groove is set for inlay card circuit breaker operating handle, make both can reach the effect of interlock, both separation convenient, use more convenient again.
