Above-mentioned a kind of fixture with double thread bar, the external screw thread that the upper outside of described hole internal thread and described threaded rod is provided with is complementary, and the external screw thread that the internal thread that is provided with in described push pipe and described threaded rod lower outside are provided with is complementary.
Above-mentioned a kind of fixture with double thread bar, described push rod outside vertical is provided with a poke rod.
Above-mentioned a kind of fixture with double thread bar, described top board and base plate are parallel to each other.
Above-mentioned a kind of fixture with double thread bar, described base plate is provided with a rectangular recess in a side of top board.
Above-mentioned a kind of fixture with double thread bar is provided with a through hole in the middle part of described threaded rod, is provided with a latch in described through hole.
A kind of fixture with double thread bar of the present utility model, adopted the following effect that has of as above scheme:
1, make push pipe can withstand workpiece in base plate by stirring the push pipe on poke rod rotation threaded rod and stirring latch rotation threaded rod, workpiece can firmly be fixed on base plate;
2, make simultaneously the operation of the detection faster convenience that becomes, reduce the operation of adding cushion block.
Description of drawings
The detailed description of non-limiting example being done by reading the following accompanying drawing of reference, the further feature of utility model, it is more obvious that purpose and advantage will become.
Fig. 1 is a kind of generalized section with fixture of double thread bar of the utility model.
As scheme reference: base plate 1, top board 2, support 3, through hole 4, push rod 5, hole 6, threaded rod 7, push pipe 8, poke rod 9, rectangular recess 10, latch 11, workpiece 12.
The specific embodiment
For technological means that utility model is realized, create feature, reach purpose and effect is easy to understand, lower combination specifically illustrates, and further sets forth the utility model.
Fig. 1 is a kind of fixture with double thread bar of utility model.as shown in Figure 1, a kind of fixture with double thread bar, comprise: a base plate 1 and a top board 2, be provided with support 3 between base plate 1 and top board 2, top board 2 centers are provided with through hole 4, be provided with push rod 5 in through hole 4, push rod 5 also can move back and forth in the through hole 4 of top board perpendicular to top board 2, this push rod 2 dorsad an end of base plate 1 be connected with the hydraulic means (not shown in FIG.) to control push rod 2 by hydraulic means back and forth flexible in through hole 4, push rod 5 is provided with hole 6 in an end face of base plate 1, hole 6 and threaded rod 7 upper end are joined, threaded rod 7 lower outsides are arranged with a push pipe 8.
In specific embodiment of the utility model, be equipped with internal thread in hole 6 and push pipe 8, upper outside and the lower outside of threaded rod 7 are equipped with external screw thread.
In specific embodiment of the utility model, the external screw thread that the upper outside of hole 6 internal threads and threaded rod 7 is provided with is complementary, and the external screw thread that the internal thread that is provided with in push pipe 8 and threaded rod 7 lower outsides are provided with is complementary.
In specific embodiment of the utility model, push pipe 8 outside vertical are provided with a poke rod 9, make push pipe 8 in threaded rod 7 inner rotary by stirring poke rod 9.
