Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, two parallel beams 3,6,13,20 that overhang in the present embodiment connect into an entirety by end plate 2,10,12,19, the slide rail that becomes 7,16 motions of transducer clamping assembly, the beam that overhangs can slide on backboard 1, to adapt to the plank to be checked of different-thickness.The two pairs of housing screw top boards 4,8,14,17 and housing screw 5,9,15,18 can move on beam overhanging, and in the time tightening housing screw, whole basic machine just can be fixed on tested wood materials 11.
The head of beam of overhanging has and is similar to the structure that tenon is the same, matches with the chute on backboard 1, and the beam that makes to overhang can move up and down in chute.The beam sides that overhangs is also processed the chute penetrating, universal overlap joint piece 705 in probe clamping assembly 7,706(are as accompanying drawing 2) can in chute, move around, make whole probe clamping assembly there is degree of freedom along chute direction (X to), necessary time, can probe be clamped to assembly by screw and be fixed on and overhang on beam.The latter half has the slide rail identical with the first half and probe clamping assembly.
The side of housing screw top board 5,9,15,18 has and is similar to the structure that tenon is the same, can be inserted in the chute of the beam that overhangs and can be fixed on slide rail, housing screw 5,9,15,18 with matching can be fixed on whole frame on plank to be checked or by sample to be checked and be clamped in frame, for the compression of follow-up probe provides stable condition.
Probe clamping assembly as shown in Figure 2, probe clamping assembly is mainly by clamping screw 701, handle 702,703, nut 704, universal overlap joint piece 705,706, spring top board 727, spring conductor rod 732,733,734,735, spring 723,724,725,726, probe fixed head 718 and probe clip 714,717 compositions.Match with the axle head of universal overlap joint piece 705,706 in two holes of universal adapting piece 704 sides, universal adapting piece 704 can be rotated around the axis of universal overlap joint piece 705,706, make it to have the rotary freedom of A axle, namely make the probe 713 of below there is the degree of freedom of rotating along A axle.Screw 736,737 through universal adapting piece former and later two holes be tightened on nut 738, nut 738 can be rotated around former and later two axially bored lines of universal adapting piece, make it to have the rotary freedom of B axle, namely make the probe 713 of below there is the degree of freedom of rotating along B axle.So far probe can a bit be done the swing of any direction within the specific limits around space, has realized the adjustment of any attitude.Probe clip 714 and 717 can press from both sides surely on probe 713 by tightening screw 715,716, the upper surface of probe clip 714 and 717 respectively has two screws, screw 708,709,710,711 is tightened in the screw of probe clip 714 and 717 upper surfaces through the chute of probe fixed head 718 both sides, make to pop one's head in 713 and the probe clip 714 and 717 of fixed thereon can move along the chute axis direction of probe fixed head, make probe there is the degree of freedom along X-direction.Spring conductor rod 732,733,734,735 is admittedly tightened and is fixed on probe fixed head by nut 719,720,721,722 after passing the through hole on probe four angles of fixed head, through hole on 727 4 angles of spring top board matches with spring conductor rod, and fixing by nut 728,729,730,731, spring top board can be moved up and down along the axis direction of spring conductor rod.Between spring top board and probe fixed head, have spring 723,724,725,726, it is upper that the snap-in force of spring top board is not directly delivered to probe, but pass to probe by spring, thereby reached the controlled requirement of snap-in force.The shaft part of clamping screw 701 lower ends matches with the center pit of spring top board with the shaft shoulder, and locked in center pit by shaft end ring 707, clamping screw can only be rotated around spring top board center pit axis, so just ensured that the probe of lower end does not rotate along with the rotation of screw rod in the time that rotary screw presses down, probe has been passed in the motion only screw rod being moved up and down.Clamping screw 701 matches with nut 738 to move and has realized the degree of freedom of probe along screw axis (Z axis) direction, so far, probe has had X, Y, Z and A, the axial degree of freedom of B, can in space, carry out free-position adjustment, meet the requirement of testing environment to Ultrasonic NDT fixture.Probe in the present embodiment is selected the nonmetal probe of Guangdong Shantou Goworld Co., Ltd. Ultrasonic Instrument Branch Company, and probe model is 100K-40F.
