Description
Technical field
The utility model relates to a kind of parts pick-up unit, especially relates to a kind of contactor and opens apart from excess of stroke measurement mechanism.
Background technology
In order to guarantee the operate as normal of contactor, all stipulated the requirement of the clearance between open contacts excess of stroke in the design, but, all will carry out the clearance between open contacts excess of stroke for this reason when test product dispatches from the factory and measure because part's machining errors and rigging error cause clearance between open contacts excess of stroke instability.Manual method commonly used makes contact contact, and is furnished with dial gauge and pilot lamp, thereby measures the opening apart from the excess of stroke of each phase.But this method speed is slow, precision is low, and the labour intensity height, is unfavorable for large-lot production.
The utility model content
The purpose of this utility model is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of measuring speed is fast, precision is high, and adopts robotization, and the contactor that can enhance productivity is greatly opened apart from excess of stroke measurement mechanism.
The purpose of this utility model can be achieved through the following technical solutions: a kind of contactor is opened apart from excess of stroke measurement mechanism, it is characterized in that, this device is by test product clamping platform, control the controller of whole device and be arranged on opening of test product clamping platform side and form apart from excess of stroke monitor station, described opening apart from excess of stroke monitor station comprises support, be arranged on the slide unit on the support, the slide unit that is connected with slide unit drives cylinder, described slide unit is provided with a plurality of powered electrodes, screw mandrel, stepper motor, measure assembly, line slideway, described powered electrode closely contacts with the contact of test product, one end of described screw mandrel is connected with stepper motor, the other end of described screw mandrel is threaded with the measurement assembly, described measurement assembly is set on the line slideway, formation can be along the syndeton of line slideway slip, described measurement assembly comprises sounding rod, magnet, the make-and-break signal contact, the termination of described sounding rod one end is connected with the touching of the armature post of test product, the other end of described sounding rod and magnet adhesive, this end termination are provided with a contravention of make-and-break signal contact.
Described powered electrode is provided with 4 pairs.
Compared with prior art, the utlity model has following advantage:
1, degree of accuracy height.Owing to adopt stepper motor as power, use high-speed collection card (PCI-1712) to gather contact adhesive signal again, what therefore draw opens apart from excess of stroke accuracy to size height.
2, the fast throughput rate of speed is fast.Owing to adopt the high-speed collection card of multichannel, therefore a stepper motor motion just can be measured opening apart from excess of stroke data of three-phase, so the throughput rate height, and an about test product only needs 5-7 second.
3, automaticity height.Because adopt computer control, cylinder and stepper motor are power source, therefore as long as, just can measure automatically by the one push start signal.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan structure synoptic diagram of Fig. 1.
1 is that test product, 2 is that powered electrode, 3 is that sounding rod, 4 is that magnet, 5 is that line slideway, 6 is that signal contact, 7 is that screw mandrel, 8 is that slide unit, 9 is that stepper motor, 10 is a slide unit driving cylinder among Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1 and Figure 2, a kind of contactor is opened apart from excess of stroke measurement mechanism, and this device is by the controller (for commercially available controller) of the test product clamping platform that is used for the clamping test product, the whole device of control and be arranged on opening apart from excess of stroke monitor station of test product clamping platform side and form.This is opened apart from excess of stroke monitor station and comprises support, is arranged on the slide unit 8 on the support, the slide unit driving cylinder 10 that is connected with slide unit 8.Slide unit 8 is provided with 4 pairs of powered electrodes 2, screw mandrel 7, stepper motor 9, measures assembly, line slideway 5.Measure assembly and comprise sounding rod 3, magnet 4, make-and-break signal contact 6.The termination of sounding rod 3 one ends is connected with the touching of the armature post of test product 1.The other end of sounding rod 3 and magnet 4 adhesives, this end termination are provided with a contravention of make-and-break signal contact 6.When measuring, powered electrode 2 closely contacts with the contact of test product major loop and switches on.One end of screw mandrel 7 is connected with stepper motor 9, the other end of screw mandrel 7 is threaded with the measurement assembly, measuring assembly is set on the line slideway 5, formation can be along the syndeton of line slideway 5 slips, when stepper motor 9 rotates, can drive screw mandrel 7 rotations, on line slideway 5, advance thereby drive sounding rod 3.
The utility model adopts stepper motor to replace the test product adhesive by mechanical drive, test product is in the simulation adhesive, the test product contact signal that records by high-speed collection card, displacement signal with stepper motor is combined to again, can show opening apart from the excess of stroke of each phase on computer screen, what such stepper motor motion can be measured three-phase opens apart from the excess of stroke degree of accuracy height, and speed is fast, has reached test product and has detected requirement.Test product 1 arrives the relevant position, slide unit drives cylinder 10 actions moves forward slide unit 8, make the powered electrode 2 and the contact of test product major loop combine closely and switch on, stepper motor 9 action this moment makes screw mandrel 7 rotations drive sounding rod 3 to advance on line slideway 5, be not subjected to external force at sounding rod 3 and do the time spent, sounding rod 3 is held by magnet 4, this moment, signal contact disconnected, run into the armature post of test product 1 when sounding rod 3 after, sounding rod 3 is thrown off with magnet 4, next two signal contact 6 conductings, stepper motor begins numeration, when sounding rod 3 pushes up conducting to the normally opened contact of each phase, the stroke of stepper motor 9 be exactly each phase opened apart from.Next make test product 1 energising adhesive, at this moment two signal contacts 6 disconnect, stepper motor 9 is rotated, driving slide unit 8 advances, after can making sounding rod 3 run into the armature post of test product 1 so again, two signal contacts 6 are connected, be exactly total the total kilometres journey of stepper motor 9 at this moment, computing machine is according to total journey and open distance and calculate each excess of stroke mutually automatically, and is presented on the computer screen.
