Technical problem to be solved in the utility model provides the ATE (automatic test equipment) of mechanical component in a kind of earth leakage protective device, can carry out integration test to the various performances of the mechanical component of earth leakage protective device, guarantees that mechanical component reaches designing requirement.
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See figures.1.and.2, be respectively the ATE (automatic test equipment) stereographic map and the vertical view of mechanical component in the described earth leakage protective device of the utility model embodiment.
Described equipment comprises plant bottom case 10, test table 20, reaches test fixture.
Described plant bottom case 10 is octagon, and it is provided with 8 frock erecting frames, is respectively applied for 8 proving installations of the described test fixture of fixed installation.
Described test table 20 is installed on the described plant bottom case 10, and its axis overlaps with the axis of described plant bottom case, makes described test table 20 to rotate around the axis of described plant bottom case 10.Along the circumference of described test table 20, evenly be provided with 8 product mount pads 201 to be measured successively, be used for fixing and place described product to be measured.
When described test table 20 during with respect to plant bottom case 10 transfixions, must satisfy each product mount pad 201 to be measured just in time with a proving installation over against, specifically as shown in Figure 2; When described test table 20 when the axis of described plant bottom case 10 rotates, its each angle of rotating must just in time equal the angle between the adjacent proving installation of the two covers axis, make that when test table 20 stops operating described product mount pad 201 to be measured still is an one-to-one relationship with described proving installation.With Fig. 2 is that example describes, and evenly is provided with 8 cover proving installations among the figure, and the angle between then per two adjacent proving installation axis is 45 degree, and then described test table 20 each angles of rotating also can only be 45 degree.
The 8 cover proving installations that described test fixture comprises are followed successively by by its installation site: start bit 301, first running-in machine 302, second running-in machine 303, major and minor axis proving installation 304, break-make property testing device 305, tripping force proving installation 306, position measurement device 307, device for dotting 308.
Wherein, described start bit 301 is a product inlet to be measured, also is products export to be measured simultaneously.When test table 20 stopped operating, described operating personnel took off the product to be measured on the product sheet mount pad 201 to be measured that is currently located at described start bit 301 places and reappose a new product to be measured.
What deserves to be explained is, in the present embodiment, described product mount pad 201 to be measured is provided with spring pressuring plate, when operating personnel are placed on described product to be measured on the described mount pad 201, described spring pressuring plate can compress described product to be measured automatically, to guarantee that described product to be measured is not moved in test table 20 rotations and the test process.
Simultaneously, the left and right sides of described start bit 301 is respectively arranged with two start buttons, shown in button 301a and 301b among Fig. 1 and Fig. 2.Described start button is used to control the rotation of described test table 20.Have only when two start buttons are pressed simultaneously, described test table 20 just can rotate, and only rotates once, is 45 degree.This design is in order to guarantee operator's safety.When the operator rotates at control test table 20, must respectively right-hand man's a finger be pinned a start button, could make test table 20 rotate.Thus, in the time of can guaranteeing that test table 20 rotates, two hands of operator all are within the safe range, avoid taking place work accident.
Among the utility model embodiment, the structure of described first running-in machine 302 and second running-in machine 303 is identical, therefore, is that example describes with first running-in machine 302 only.
