Embodiment
Below in conjunction with the drawings and specific embodiments, the connection clamping force, the pulling-out force proving installation that the bearing load power of proposition that the utility model adopts are connected product further describe.
Please refer to Fig. 1, Fig. 3, the described bearing load power of the present embodiment connects connection clamping force, the pulling-out force proving installation of product, comprises the tension tester (not shown); Test fixture 7, described tension tester connects described test fixture 7, and to being arranged to be measured 1 in described test fixture 7, to be measured ground stereographic map can referring to Fig. 2, carry out the pulling-out force test.Proving installation also comprises the clamping force test department, and described clamping force test department comprises rigid sheet 2, and described rigid sheet one end is held in described to be measured 1, other end connecting rope 4; Described rope 4 passes a fixed pulley 3, and the other end of described rope connects weight 5; Sensor 6, when described weight 5 positions change, in order to detecting the position of weight 5, described sensor 6 and described tensile test mechatronics, and the weight position signalling is reached tension tester.Described installation of sensors is in the side of described weight 5, horizontal level is lower than described weight, and described sensor 6 horizontal levels 2mm place below described weight 5 in the present embodiment is when described weight falls, through before described sensor, sensor produces induced signal.
Process of the test is as follows in the present embodiment:
1, rigidity thin slice 2 is seated in two connecting test spares 1 that are connected and installs, make it clamped.
2, test block 1 is arranged in tension tester test fixture 7, connects 2 one of rigidity thin slices with connecting rope 4, by pulley 3, connects weight 5;
3, adjust rope lengths, make inductor 6 be located at the side of weight 5 lower than weight 2mm left and right.
4, puller system is started working and is tested, and when test block 1 produces distortion, occurs becoming flexible, and weight 5 pulls the rigidity thin slice 2 that is held in test block 1.
5, weight 5 glides, and to this point of microcomputer tensile test " power-position " curve record, is the maximum clamping force of maximum test block by inductor 6 communication just at this moment.
6, continue to test with pulling-out force with advancing test, acquisition pulling-out force test result.
Compared with prior art, the connection clamping force that is used for bearing load power connection product that employing the utility model proposes, the proving installation of pulling-out force, when bearing load power edge joint product is connected clamping force and pulling-out force, test, realized fast, simply realizing test purpose.
Above in order to illustrate and to describe to the description of the utility model preferred embodiment, be not want the utility model limit or be confined to disclosed concrete form, obviously, may make many modifications and variations, these modifications and variations may be obvious to those skilled in the art, within should being included in the scope of the present utility model by the appended claims definition.
