Compared with the prior art, the testing device has the advantages that the measuring accuracy is high, the measuring range is wide, the automatic degree is high and the like.
Description
Technical field
The utility model relates to a kind of product performance test device, especially relates to a kind of electrical apparatus release impulsive force proving installation.
Background technology
In order to guarantee the normal separating brake of air-break, generally all adopting magnetictrip is power source, when the external world sends into the separating brake electric signal, just can make the magnetictrip action, the electromagnetic force that is produced by it makes electrical apparatus release activity axle impact the stressed lever of brake separating mechanism, thereby makes the air-break separating brake.In order to guarantee normal separating brake, its electromagnetic force must be greater than the mechanical force of brake separating mechanism, otherwise normal separating brake, so must carry out the test of impulsive force during product export.Generally do not test in the factory at present, and depend on product design, the product that must cause like this coming into the market has part to be unacceptable product, when the user uses substandard product, gently then causes any property loss, and is heavy then cause casualties.Therefore a kind of device that magnetictrip is carried out the impulsive force test of utility model is a problem demanding prompt solution.
The utility model content
The purpose of this utility model is exactly that a kind of measuring accuracy height, measurement range is wide, automaticity is high electrical apparatus release impulsive force proving installation are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of electrical apparatus release impulsive force proving installation; it is characterized in that; this device comprises support; controller and be arranged on stepper motor on the support; shaft coupling; screw mandrel; the slide unit table top; web joint; the shock sensors seat; shock sensors; impact head; anchor clamps; quick tong; protective cover; linear potentiometer; described stepper motor is connected with screw mandrel by shaft coupling; described screw mandrel is threaded with the slide unit table top; driving the slide unit table top slides on support; one end of described web joint is fixed on the slide unit table top; the other end of described web joint is provided with the shock sensors seat; this shock sensors seat is provided with shock sensors; described shock sensors is connected with impact head; described anchor clamps are located at the impact head anterior position; these anchor clamps are provided with quick tong; described protective cover is connected with support; and anchor clamps and impact head are covered described controller and stepper motor; shock sensors; linear potentiometer connects.
Described protective cover is provided with handle.
Compared with prior art, the utlity model has following advantage:
1, owing to adopt shock sensors, therefore the impulsive force ratio of precision of measuring is higher.
2, because the closed loop slide unit table top that adopts stepper motor and linear potentiometer to form, so displacement is very accurate, and displacement can change by designing requirement, therefore can measure the product of complete series.
3, automaticity height.As long as owing to adopt controller, and to adopt stepper motor be power source, and shock sensors is the signal message source, therefore by the one push start button, just can finish automatically and measure and the function of judgement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1 be stepper motor, 2 for shaft coupling, 3 for screw mandrel, 4 for the slide unit table top, 5 for web joint, 6 for the shock sensors seat, 7 for shock sensors, 8 for impact head, 9 for quick tong, 10 for protective cover, 11 for handle, 12 for electrical apparatus release, 13 for anchor clamps.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1; a kind of electrical apparatus release impulsive force proving installation, this device comprise support, controller and are arranged on stepper motor 1 on the support, shaft coupling 2, screw mandrel 3, slide unit table top 4, web joint 5, shock sensors seat 6, shock sensors 7, impact head 8, anchor clamps 13, tong 9, protective cover 10, handle 11, linear potentiometer fast.Stepper motor 1 is connected with screw mandrel 3 by shaft coupling 2.Screw mandrel 3 is threaded with slide unit table top 4, drives slide unit table top 4 and slides on support.One end of web joint 5 is fixed on the slide unit table top 4.The other end of web joint 5 is provided with shock sensors seat 6, and this shock sensors seat 6 is provided with shock sensors 7.Shock sensors 7 is connected with impact head 8.Anchor clamps 13 are located at impact head 8 anterior position, and these anchor clamps 13 are provided with quick tong 9.Protective cover 10 is connected with support, and anchor clamps 13 and impact head 8 are covered.Protective cover 10 is provided with handle 11.Controller is connected with stepper motor 1, shock sensors 7, linear potentiometer.
Because product when mounted, between electrical apparatus release and the brake separating mechanism certain distance is arranged, just to measure the impulsive force of leaving activity axle certain distance, at this moment just to measure the original position of electrical apparatus release activity axle earlier, make shock sensors slow astern set a distance then, so just can measure the impulsive force of requirement.The utility model adopts stepper motor 1 and linear potentiometer to form the closed loop slide unit, shock sensors 7 is installed on the slide unit table top 4, when stepper motor 1 rotates, shock sensors 7 is advanced, when shock sensors 7 is run into electrical apparatus release activity axle, just be set at the original position of electrical apparatus release, and then make stepper motor 1 retreat the certain distance of product requirement, just can measure the electrical apparatus release impulsive force of assigned position.At first manually electrical apparatus release (product) 12 is put into anchor clamps 13, compress electrical apparatus release 12 with quick tong 9 then, and connect the electrical apparatus release power lead, close protective cover 10 down with handle 11 at last.Next just can be by start button, equipment just detects automatically: at first stepper motor 1 inhour is rotated, drive shaft coupling 2 and screw mandrel 3 rotations, thereby slide unit table top 4 is travelled forward, it drives web joint 5, shock sensors seat 6, shock sensors 7 and impact head 8 and travels forward, and when impact head 8 was run into the activity axle of electrical apparatus release 12, shock sensors 7 was sent signal, the original position that arrives electrical apparatus release 12 is described, stepper motor 1 stops operating immediately.Next stepper motor 1 clockwise rotates, and drives impact head 8 and moves backward, and linear potentiometer begins to measure mobile size simultaneously, (can set) after meeting the requirements of displacement, and stepper motor 1 just stops operating.Make electrical apparatus release 12 energisings at last, the activity axle of electrical apparatus release 12 is ejected, when running into impact head 8, shock sensors 7 just can indicate corresponding impulsive force value, and compares with required value, judges whether this electrical apparatus release 12 is qualified, and shows on screen.
