But the inventor finds that there are the following problems at least in the prior art:
Lack the device that is specifically designed to stretching neutron absorbing layer carrier in the prior art.
Summary of the invention
The invention provides a kind of neutron absorbing layer carrier stretching device, the neutron absorbing layer carrier that is used to stretch makes the neutron absorbing layer carrier have higher flatness.
For achieving the above object, the present invention solves the problems of the technologies described above the technical scheme that adopted as described below:
A kind of neutron absorbing layer carrier stretching device, comprise the clamping unit that is used to clamp described neutron absorbing layer carrier, described neutron absorbing layer carrier is positioned on the worktable, described clamping unit one end is connected with fixed block on being fixed in described worktable by spring, described fixed block is provided with screwed back shaft, described back shaft one end withstands described draw unit, and described back shaft moves and realize stretching to described neutron absorbing layer carrier along screw thread corresponding on the described fixed block under the acting force of described spring.
Further, described clamping unit has four, is arranged in four limits of the neutron absorbing layer carrier of rectangle, wherein, one end of two adjacent clamping units is connected with fixed block on being fixed in described worktable by spring respectively, and two other clamping unit directly is fixed on the worktable.
Further, described clamping unit comprises some elbow folders, and described elbow folder has clamp.
Further, a side of the described neutron absorbing layer carrier of the clamping of described clamp is provided with rubber strip.
Further, the draw direction of described neutron absorbing layer carrier is X, Y direction, and described elbow folder is evenly arranged along described X, Y direction.
Further, be connected with equally spaced spring more than two between described clamping unit and the described fixed block.
The present invention is after having taked technique scheme, described back shaft moves horizontally along screw thread rotation and along draw direction, under the acting force of described spring, realize stretching to described neutron absorbing layer carrier, make the neutron absorbing layer carrier have higher flatness, stretching carrier area is big, the stretching required time is short, can realize that large tracts of land, many materials, high-precision neutron absorbing material carrier stretch.
Description of drawings
Fig. 1 is the structural representation of neutron collimator;
Fig. 2 is the structural representation of embodiment of the invention neutron absorbing layer carrier stretching device.
Embodiment
Present invention is described below in conjunction with the drawings and specific embodiments.
Embodiment
The embodiment of the invention provides a kind of neutron absorbing layer carrier stretching device, and as shown in Figure 2, the embodiment of the invention can realize that to the stretching of neutron absorbing layer carrier at X, Y both direction the direction of diagram arrow is the draw direction of X, Y.Neutron absorbing layer carrier 6 is fixed on the worktable 5, neutron absorbing layer carrier stretching device comprises the clamping unit 3 that is used to clamp neutron absorbing layer carrier 6, clamping unit 3 one ends are connected with fixed block 4 on being fixed in worktable 5 by spring, fixed block 4 is provided with screwed back shaft 8, back shaft 8 one ends withstand clamping unit 3, back shaft 8 moves and makes clamping unit 3 produce displacement under the acting force of described spring along screw thread corresponding on the fixed block 4, realizes the stretching to described neutron absorbing layer carrier 6.
As shown in Figure 2, clamping unit has four, be arranged in four limits of the neutron absorbing layer carrier of rectangle, wherein, one end of two clamping units 3 that the right side is adjacent with upside is connected with fixed block 4 on being fixed in described worktable by spring respectively, in the present embodiment, in the through hole of spring between clamping unit 3 and fixed block 4, two other clamping unit 3 of left side and downside directly is fixed on the worktable.Like this, the left side of neutron absorbing layer carrier stretching device, downside are stiff end, and right side and upside are the mobile terminal.Certainly, the present invention is not limited to the arrangement form among the embodiment, is the arrangement form of mobile terminal etc. around for example, and stiff end of the present invention or mobile terminal also are not limited to the fixed form among the embodiment.
Clamping unit 3 can move freely at X or Y direction among Fig. 2, be connected with equally spaced spring more than two between clamping unit 3 and the fixed block 4, back shaft 8 has screw thread, can control the spacing of clamping unit 3 and fixed block 4, back shaft 8 is slow when mobile, and clamping unit 2 can retreat equably.
