The specific embodiment

The embodiment of topping machanism described in the utility model is described below with reference to the accompanying drawings.Those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode or its combination.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.In addition, in this manual, accompanying drawing draws not in scale, and identical Reference numeral is represented identical part.

Fig. 1 is sketch map, shows the described die body support of first embodiment of the present utility model.Fig. 2 is sketch map, shows the fixed cell of the described die body support of Fig. 1 and being connected of rotating unit.Fig. 3 is sketch map, shows the position-limiting unit of the described die body support of Fig. 1.Fig. 4 is sketch map, shows the position-limiting unit of the described die body support of Fig. 1 and being connected of rotating unit.Fig. 5 is sketch map, shows the load bearing unit of the described die body support of Fig. 1.

As shown in Figure 1, described die body support 1000 fixed cells 100, rotating unit 200, position-limiting unit 300 and load bearing unit 400 of first embodiment of the present utility model.

Fixed cell 100 has at least one through hole 101.Fixed cell 100 is installed in the patchhole on the CT bed board, thereby die body support 1000 and die body (not shown) are fixed to CT fixed bed or CT moving bed.

As shown in Figure 2, the parallel position on the both sides sidewall 210,220 of rotating unit 200 is provided with through hole 230, and rotating unit 200 is vertically connected at fixed cell 100, and here, fixed cell 100 removably connects with vertical being connected between the rotating unit 200.For example bolt connects, and after the through hole 201 overlapping alignment with the through hole 101 of fixed cell 100 and rotating unit 200, by through hole 101 and through hole 201, adopts nut to fix on bolt.By adjusting the chucking degree of bolt, rotating unit 200 can be around fixed cell 100 rotations.

As shown in Figure 3, have a plurality of gear mouths 340 on the side of position-limiting unit 300, for example 3, gear mouth 340 can present even distribution or uneven distribution in the side of position-limiting unit 300.By the present gear mouth 340 of conversion die body, realize that the die body (not shown) is in the change of vertical direction position.

A plurality of through holes 330 that be arranged in parallel in the two side 310,320 of position-limiting unit 300, this through hole 330 is used for the distance element roll adjustment of vertical direction, and here, the scope of distance element is less than the distance between two adjacent gear mouths, normally 5mm.The sidewall that closely causes on the same side between the through hole 330 breaks, and usually through hole 330 multiple rows is distributed.

In addition, as shown in Figure 4, position-limiting unit 300 is connected with rotating unit 200, and here, being connected between position-limiting unit 300 and the rotating unit 200 removably connects.For example, through hole 230 be arranged in parallel on the two side 210,220 of rotating unit 200, with the through hole 230 of rotating unit 200 respectively with the 330 overlapping alignment of two of position-limiting unit 300 parallel through holes after, by through hole 230 and through hole 330, adopt nut to fix on bolt.When position-limiting unit 300 needs vertically or during the horizontal direction fine setting, 5mm for example, with the bolt on the through hole 330 vertically or move horizontally a through hole 330 and get final product.And because position-limiting unit 300 is connected with rotating unit 200 bolts, position-limiting unit 300 can be rotated around rotating unit 200, further changes position-limiting unit 300 at the height of vertical direction.

As shown in Figure 5, load bearing unit 400 is connected with described position-limiting unit 300, these load bearing unit 400 1 sides have hook 410, hook 410 is hooked on the gear mouth 340 of position-limiting unit 300, the sidewall 420,430 of load bearing unit 400 opposite sides is provided with two positioning bolts 440,450, the die body (not shown) is placed between the positioning bolt 440,450.Move positioning bolt 440,450, the motive force of this horizontal direction of die body (not shown), the movement that can produce horizontal direction in the same direction simultaneously.

Fig. 6 is sketch map, shows the described die body support of second embodiment of the present utility model.Fig. 7 is sketch map, shows the clamping bolt in the use of the support of die body described in Fig. 6.As shown in Figure 6 and Figure 7, the difference of Fig. 6, Fig. 7 and Fig. 1 is, the die body support 1000 in the present embodiment ' also comprise clamping bolt 500.Load bearing unit 400 is with after position-limiting unit 300 is connected, clamping bolt 500 is by the through hole 411 on hook 410 surfaces, link to each other with the sidewall of gear mouth 340, when another sidewall of gear mouth 340 is adjacent to hook 410 inboards, locking clamping bolt 500 makes load bearing unit 400 be fixed on the position-limiting unit 300.Thus, the motif position that is positioned at load bearing unit 400 inside can not be offset, to avoid influence calibration effect.And, when reusing 1000 ' time of die body support, can be directly used in the suspension die body.

Fig. 8 is sketch map, shows the described die body support of the 3rd embodiment of the present utility model.Fig. 9 is sketch map, shows the carrying bolt in the use of the support of die body described in Fig. 8.Fig. 8, Fig. 9 and Fig. 1 and Fig. 6 difference is, the die body support 1000 in the present embodiment ' ' also comprise carrying bolt 600.Carrying bolt 600 links to each other with position-limiting unit 300 by the through hole 202 on rotating unit 200 surfaces, and carrying bolt 600 provides the support force of horizontal direction for the position-limiting unit 300 that departs from vertical direction.Thus, when position-limiting unit 300 is the axle rotation with the bolt to vertical direction at an angle the time around rotating unit 200, be subjected to the contrary vertical position that rotates to of gravity effect for fear of position-limiting unit 300 and the load bearing unit 400 that is attached thereto, provide the support force of a horizontal direction by carrying bolt 600, thereby improve the stability of position-limiting unit 300 and load bearing unit 400.

Under above-mentioned instruction of the present utility model; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment; and these improvement and distortion; all drop in the protection domain of the present utility model; those skilled in the art should be understood that; above-mentioned specific descriptions are just explained the purpose of this utility model better, and protection domain of the present utility model is limited by claim and equivalent thereof.
