An end that is connected with described clamp at described frock body is provided with T-shaped groove, and described clamp is equipped with chute on the both sides, and described clamp is stuck on the T-shaped groove of described frock body.
Described clamp is two pairs, is divided into flat grip piece and cambered surface clamp; The end that described flat grip piece (5) contacts with the knob clamped position is planar structure; The end that described cambered surface clamp contacts with the knob clamped position is globoidal structure.
The planar structure of described flat grip piece is provided with spongy layer.
On the globoidal structure of described cambered surface clamp broached-tooth design is set.
It is inboard that described flat grip piece is located at described cambered surface clamp.
The torsion-testing method of described vehicle air conditioning panel knob utilizes described vehicle air conditioning panel knob torsion-testing clamping tool to realize, may further comprise the steps:
(1) at first the air-conditioning panel knob is kept flat with surface level on, choose clamp according to air-conditioning panel knob profile, simultaneously rotation is positioned at the nut at the bolt two ends on the clamp, adjusts the clamp position, makes clamp slowly near the knob outward flange;
(2) when clamp contact knob outward flange, fine-tuning nut makes slowly locking knob of clamp, and nut stops the rotation after the knob locking;
(3) joint pin on frock body opposite side connects torque gauge, carries out the knob torsion-testing, after being completed, reads that reading gets final product on the torque gauge.
In the described step (1), when knob is " 1 " character form structure, select the flat grip piece, at first knob is placed in the middle of the flat grip piece of paired setting, then the nut of swivel bolt both sides simultaneously, nut promotes the flat grip piece and relatively moves, and makes clamp slowly near the knob outward flange; When knob is circular configuration, select the cambered surface clamp, at first knob is placed in the middle of the cambered surface clamp of paired setting, the nut of swivel bolt both sides simultaneously then, nut promotes the cambered surface clamp and relatively moves, and makes clamp slowly near the knob outward flange.
Described vehicle air conditioning panel knob torsion-testing clamping tool and torsion-testing method thereof, the technical scheme of employing has the following advantages:
At first, the frock that clamps, the clamp that arranges in pairs is connected by the mode that slide block and chute cooperate with the frock body, under the effect of power, clamp all can relatively move along the frock body, and the distance between the clamp can be regulated, and clamp can be used for the clamping and positioning of the knob of different size;
Secondly, the pinching end of clamp is to clamp the adaptive structure of contact position with knob, and described clamping tool can by flat grip piece and cambered surface clamp are set at the frock body, be applicable to the clamping and positioning demand of the knob of different profiles;
Again secondly, described clamping tool, one overlaps frock, can be suitable for the torsion-testing of the knob of multiple moulding, has saved resource; This general form clamp fixture only has a cover simultaneously, and convenient management has overcome single clamp fixture because quantity is more, uses easily and obscures, the defective of unsuitable storage and managenent;
Again secondly, described clamping tool, applicability is strong, and reliability is high, and simple to operate, easy to carry, cost of manufacture is low, and test speed is fast, high efficiency;
At last, described torsion-testing method utilizes described clamping tool to realize, this method of testing is easy to operate fast, and test speed is fast, high efficiency.
