To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the embodiment of a part of the invention, rather than whole embodiments.Based on the embodiment in the present invention, every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
In the specific embodiment of the present invention, as shown in figure 1, for the loading fixture 100 in industry CT, including：First chuck 4, the second chuck 1 and clamping limb 2.The first sunk structure 40 is provided with the surface of the first chuck 4.Second chuck 2 is movably set in the top of the first chuck 4, and provided with the second sunk structure 10 that can be alignd with the first sunk structure 40.Clamping limb 2 forms clamping face through the center of the second sunk structure 10 and in end face.Wherein, clamp area D is surrounded between first the 40, second depression 10 of depression and clamping face, clamp area D size can adjust with the activity of clamping limb 2, as shown in Figures 2 and 3.Thus, fixture 100 can clamp the detection piece of different shape and size, have versatility.
In the specific embodiment of the present invention, as shown in figure 1, the first sunk structure 40 and the second sunk structure 10 are configured to v-depression.It is readily appreciated that, the shape of the first sunk structure 40 and the second sunk structure 10 can have any shape, as long as can form certain clamp area D between the two.For example, the section of sunk structure can also be arc or semicircle.Further, clamping limb 2 is shaft-like that clamping face is plane and passes through the center of the second sunk structure 10, and can be moved in clamp area D center position area.Preferably, the width of the clamping face of clamping limb 2 is equal to or less than 1/3rd of the v-depression A/F of the first sunk structure 40.In this case, when detection piece is the metalwork of reduced size, as shown in Fig. 2 detection piece is placed in v-depression, clamping limb 2 extends its clamping face top to the surface of detection piece, and detection piece is held in fixture 100 by three geometrical clamps.In addition, when detection piece is the metalwork of large-size, as shown in figure 3, detection piece is placed in v-depression, clamping limb 2 shrinks its clamping face top to the surface of detection piece, and detection piece is by 2 five common fixed clamps of point of four side walls of two v-depressions and clamping limb in fixture 100.
In order to realize the quick opening and closing of fixture 100 and the convenience using process, in the specific embodiment of the present invention, as shown in figure 1, fixture 100 also includes lead 5 and pushing hands 6.One end of lead 5 is fixedly connected with the second chuck 1, and the other end is connected through the first 4, folder and with pushing hands 6.Thus, pushing hands 6 can be promoted when fixture 100 works makes the second chuck 1 away from the first chuck 4 in order to be put into detection piece.Preferably, the elastic caoutchouc 3 for being used for connecting the first chuck 4 and the second chuck 1 is provided with around lead 5, and then under the elastic force effect of elastic caoutchouc 3 the first chuck 4 can be made to be closed with the second chuck 1.
In order to strengthen the stability of clamping, on the surface of the first sunk structure 40 and the second sunk structure 10, and elastomeric pad 7 is fitted with the clamping face of clamping limb 2.Wherein, the elastomeric pad 7 being arranged on the first sunk structure 40 has the size bigger than the elastomeric pad 7 being arranged on the second sunk structure 10.Specifically, the elastomeric pad 7 conformed on lower grooves two side is longer than conforming to the elastomeric pad 7 on upper grooves two side.Because when detection piece is smaller, only it is clamped using lower recess and clamping limb 2, the second chuck 1 to top only can be just used when the depth for the groove that the height of detection piece is more than the first chuck of bottom 2.
In addition, elastomeric pad 7 can also play buffer protection function to detection piece.
Further, in order to avoid fixture 100 is excessive to radiation absorption, the picture quality of retained part detection piece is influenceed, the first chuck 4, the second chuck 1 and clamping limb 2 are by low density non-metallic material, for example, plastics and rubber are made.
In order to make it easy to understand, the first chuck 4 is referred to as quiet chuck by us, the second chuck 1 is referred to as dynamic chuck.As shown in figure 1, the dynamic clamping face of chuck 1 is formed by being bonded elastomeric pad 7 on V-type groove surface, to increase clamping contact area, strengthen clamping stability.Clamping limb 2 can realize the movement and fixation of its end clamping face as the case may be by moving the threaded connection of the center position of chuck 1.Two one end of lead 5 are connected through a screw thread the bare terminal end for being fastened on dynamic chuck 1, and the other end is anchored in pushing hands 6 after passing through the unthreaded hole of quiet chuck 4.Similar, the clamping face of quiet chuck 4 is also made up of V-type groove surface fitting elastomeric pad 7.Between dynamic chuck 1 and quiet chuck 4, uniform some suitable elastic caoutchoucs of root long degree on circumferencial direction of lead 5, for example, can be 4, play a part of the dynamic and static chuck of closure.
Our the use processes of the fixture 100 to the present invention carry out simple illustration below.
When fixture 100 works, pushing hands 6 is promoted first to resist the convergent force of elastic caoutchouc 3, clamp area D is to sufficiently large size for expansion, is put into detection piece.Afterwards, pushing hands 6 is unclamped, in the presence of the convergent force of elastic caoutchouc 3, the detection piece between each clamping face, due to the effect of elastomeric pad 7, enough clamped areas can be ensured to ensure the stability and fastness of clamping.When the size of detection piece is smaller, as shown in Figure 2, it is only necessary to move clamping limb 2 along the direction of quiet chuck 4 and arrive correct position, ensure that the clamping face of clamping limb 2 is contacted with detection piece, clamped.And when part is larger, as shown in figure 3, moving clamping limb 2 along the opposite direction of quiet chuck 4 arrives suitable position, principal security moves the clamping face of chuck 1 and contacts and clamp with detection piece.
In summary, fixture 100 of the invention can provide enough contacts area, and then ensure the stability of clamping by setting the clamping face of dynamic chuck 1, quiet chuck 4 to be made up of V-groove fitting elastomeric pad 7.Go for the clamping of relatively broad various sizes of detection piece by setting moveable clamping limb 2 ensure that.In addition, dynamic chuck 1, quiet chuck 4 are linked together by elastic caoutchouc 3, quick-clamping is realized on the premise of can there is enough contraction closing forces ensureing it.Finally, fixture 100 is mainly made using the plastics and rubber of low density non-metallic material, thus, the loss to ray is less, and finally ensure that will not lose detection information too much.
