Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, be arranged on for pulling capacity measurement jig of the present utility model on the desktop 11 of a frame 1, desktop is necessary for plane and horizontal positioned, to reduce the measuring error of pulling capacity tool.The pulling capacity measurement jig comprises a base 2 that is located on the desktop, base 2 is provided with a back up pad 21 of erectting, back up pad 21 is provided with a liftable dynamometer 3, and dynamometer 3 is by on the screw mandrel 4 that is connected a transmission, and screw mandrel 4 is arranged on the back up pad 21.Wherein, the two ends of screw mandrel 3 are connected on the two screw mandrel fixed blocks 41 that are arranged on the back up pad 21, and be provided with two parallel with screw mandrel 4 guide rod 42 in the both sides of screw mandrel 4, motor 5 is arranged on the below of screw mandrel 4, it is by being fixed on the motor fixing base 51, and this motor fixing base 51 is arranged on the screw mandrel fixed block 41 that is positioned at the below.
Dynamometer 3 is connected on the dynamometer fixed block 6, on guide rod 42, then be provided with sliding shoe 43, dynamometer fixed block 6 is connected sliding shoe 43 front ends, drives dynamometer 3 thereby the sliding shoe on the guide rod 42 is movable, thereby can regulate rising or the decline of dynamometer 3 by the activity of screw mandrel 4.Simultaneously, be arranged on back up pad 21 1 sides in order to the display screen 44 of regulating real screw mandrel 3 parameters, and be connected with screw mandrel 4, display screen is provided with power light 441 and starting switch 442, and on the main interface 443 of display screen 44 manual and automatic two parts is arranged, and can switch by " manually " or " automatically " printed words that point touches on it, but the numeral input speed numerical value of 44 tactile pages of display screen, change parameter, or the digital zero clearing that will change are confirmed the parameter that sets behind the tactile acknowledgement key of point.
Pull bar below dynamometer 3 or stay cord are provided with a hook 31, below dynamometer hook 31, be provided with a hook fixed block 7, this hook fixed block 7 is arranged on and is positioned at back up pad 21 the place aheads on the base 2, hook fixed block 7 is provided with a hook 71, hook fixed block 7 can be fixed on the base 2 by hexagon socket head cap screw, hook 71 be positioned at dynamometer hook 31 under, and can two hooks 31,71 be positioned on the same vertical straight line by regulating hook fixed block 7.Simultaneously, also can carry out parameter on the dynamometer 3 and set, dynamometer 3 is provided with the panel 32 of a debugging, which is provided with on ﹠ off switch and zero key, and can write down hook 31 values of thrust of surveying at the display screen of panel when pressing " PEAK/TRACK ".
When the pulling capacity measurement jig will carry out the pulling capacity test to product, for in the present embodiment being plastic product for cast, hook 71 on hook 31 on the dynamometer and the hook fixed block 7 is adjusted to the appropriate location, product is hooked between two hooks, regulating hook fixed block 7 is positioned on the same vertical straight line two hooks, two hooks catch on product cast gate diagonally opposing corner up and down, after treating that product is put well, regulating screw mandrel 4 automatic modes rises, the drive dynamometer rises, and product on dynamometer the hook uphill process and pullled by the application of force upwards, after breaking, product stops, the dynamics when breaking is measured and noted down down to dynamometer 3, can learn the maximum holding capacity of product by dynamometer 3, tests out the pulling capacity of product.Need to prove, what test in the present embodiment is the plastic product of cast, for other products, product as sheet, two above-mentioned hooks can be set to clamp structure respectively, so can corresponding fixture be set in order to being connected the two ends of product at dynamometer and hook fixed block according to the form of different product, thereby the lower end of product is fixed, the upper end is connected on the dynamometer to drive by dynamometer and upwards spurs and carry out dynamometry simultaneously.
The use of pulling capacity measurement jig of the present utility model is as follows: at first, the socket that plugs in presses the button the main interface of demonstration on the screen to be shown, and the revolution parameter that sets respectively earlier manually or automatically is set at main interface.The on ﹠ off switch of pressing on the dynamometer panel is opened dynamometer, press " ZERO " build make zero after, press " PEAK/TRACK " back on the dynamometer panel and can write down the maximum pull that measures in the drawing process on the dynamometer display screen when measuring.During measurement, set earlier the rotating speed that lock pin is manually or automatically wanted respectively, again under manual mode, point touches " rising " and " decline ", link up with to correct position for two about adjusting, hexagon socket head cap screw on the adjusting base two hooks is up and down adjusted on the vertical straight line, hook catches on product cast gate diagonally opposing corner, after treating that product is put well, automatic mode rises, and stops after product is broken, at this moment, the numerical value that shows on the dynamometer is the final value of thrust of breaking product, writes down data, finishes a work flow.
Pulling capacity measurement jig of the present utility model, product is fixed between two fixtures, wherein an end is fixed, the other end is then by being fixed on the fixture on the dynamometer, simultaneously, dynamometer can carry out the lifting activity by the screw mandrel that connects a transmission, dynamometer rising activity, carry out drawing and break until product being fixed on product between two fixtures, and test out pulling force numerical value by dynamometer, thus can detect the pulling capacity of product, it is simple in structure, the operation of can applying in a flexible way of each structure, easy to use.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
