2) subject cable is not fixed reliably:Cable is tested in this device to be disposed on cable deck, and The function of clamping fixation is not provided with, cable is tested in test process may move so that electric arc fails.
3) waste of material:Comprehensively and effectively, it is necessary to change steel blade often, certain economy can not be caused by spent material Loss.
The content of the invention
The purpose of this utility model is to provide a kind of parallel arc generating means that can continuously produce parallel arc.
In order to achieve the above object, the technical solution of the utility model there is provided it is a kind of be used continuously it is full-automatic simultaneously Join arc generating device, including be arranged in the upper and lower Dao Qie mechanisms and transfer mechanism of table top bottom plate, will be flat where table top bottom plate Face is set to X/Y plane, it is characterised in that Dao Qie mechanisms include Z axis drive mechanism, non-conductive bottom plate and non-conductive lever arm, non-to lead One end of electric lever arm is connected with Z axis drive mechanism, and the other end is provided with steel blade, and the middle part of non-conductive lever arm is with usheing to seat Bearing hinge connection, rolling bearing units are fixed on table top bottom plate, and non-conductive lever arm is driven around non-conductive lever arm by Z axis drive mechanism Pin joint between rolling bearing units is rotated, and subject cable is fixed on non-conductive bottom plate by active grab, non-conductive lever After arm rotates, drive steel blade to be tangentially tested cable, cause short circuit to trigger parallel arc;
The oblique translation of non-conductive bottom plate is driven by transfer mechanism.
Preferably, the Z axis drive mechanism includes Z axis servomotor, Z axis servomotor driving electric cylinders module, electric cylinders mould Group drives floating hinge joint, and one end of the non-conductive lever arm is connected with floating hinge joint.
Preferably, the transfer mechanism include 30 ° oblique with Y-axis installation X-axis servomotors and with the non-conductive bottom The spacing detection lug of sensing of plate synchronization action, X-axis servomotor drive the non-conductive bottom plate and the spacing detection lug of sensing synchronous Oblique translation, right-hand member photoelectric limit switch and left end are respectively equipped with two extreme positions for sensing spacing detection lug translation Photoelectric limit switch.
Preferably, the subject cable is fixed on the non-conductive bottom plate by two sets of active grabs, the steel Subject cable of the insert tangential processed between two sets of active grabs.
The utility model has the following advantages that:Parallel arc can be continuously generated, and does not need manual intervention;Ensure that by Examination cable is reliably fixed, so as to ensure that successful stability occurs for parallel arc;The electric arc effect in view of detection process Damage to consumptive material, farthest improve the utilization rate of consumptive material.
Brief description of the drawings
Fig. 1 is prior art parallel arc fault generating means front view;
Fig. 2 is the full-automatic parallel arc generating means equal axes axonometric drawing provided by the utility model being used continuously;
Fig. 3 is the full-automatic parallel arc generating means side view provided by the utility model being used continuously.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
With reference to Fig. 2 and Fig. 3, a kind of full-automatic parallel arc generating means cloth being used continuously provided by the utility model The position up and down of table top bottom plate 5 is placed in, top is mainly Dao Qie mechanisms, and bottom is transfer mechanism.
Dao Qie mechanisms are fixed on non-conductive bottom plate 6 by active grab 14 by cable 7 is tested.Z axis servomotor 8 drives Electric cylinders module 9 drives floating hinge joint 10 to move, so that non-conductive lever arm 11 rotates around rolling bearing units 13, drives steel Blade 12 is tangentially tested cable 7, causes short circuit to trigger parallel arc.The cutting edge of steel blade 12 is caused to damage in electric arc effect Or after the point of contact damage of subject cable 7, Z axis servomotor 8 inverts, and drives remaining part, finally makes steel blade 12 remote It is tested cable.
Now, the X-axis servomotor 3 of 30 ° of installations oblique with Y-axis in the bottom of table top bottom plate 5, i.e. transfer mechanism is transported Turn, drive non-conductive 6 oblique translation of bottom plate, stop in place, Z axis servomotor 8 operates again, drives its remaining part Part, steel blade 12 is tangentially tested cable 7, again result in short circuit so as to trigger parallel arc.
Right-hand member photoelectric limit switch 1 and left end photoelectric limit switch 2 are watched by sensing spacing detection lug 4 to limit X-axis The stroke range of motor 3 is taken, ensures the safety of mechanism kinematic.
The utility model can continuously generate parallel arc, and not need manual intervention.Implementation is:In electric arc effect After causing the cutting edge of steel blade 12 to damage or be tested the point of contact damage of cable 7, Z axis servomotor 8 inverts, and drives its remaining part Part, finally make steel blade 12 away from subject cable.Now, the X-axis servomotor 3 of 30 ° of installations oblique with Y-axis operates, and drives Non-conductive 6 oblique translation of bottom plate, stops in place, and Z axis servomotor 8 operates again, drives remaining part, finally makes Steel blade 12 is tangentially tested cable 7, again results in short circuit so as to trigger parallel arc.
The utility model ensure that subject cable is reliably fixed, so as to ensure that successful stability occurs for parallel arc. Embodiment is:It is fixed on using two sets of active grabs 14 by cable 7 is tested on non-conductive bottom plate 6.
The utility model damage of electric arc effect to consumptive material in view of detection process, farthest improves consumptive material Utilization rate.Its implementation is:The X-axis servomotor 3 of 30 ° of installations oblique with Y-axis operates, and drives non-conductive bottom plate 6 oblique Translation so that steel blade 12 is tangent in the position different compared with when testing before from subject cable 7 when testing again, causes short Road is so as to triggering parallel arc.So it is being used repeatedly until that the whole cutting edge of steel blade gathers spot failure, or is being tested cable After suitable point of contact can not being provided again, just need to change steel blade and be tested cable.
