A kind of holding device
Technical field
The utility model belongs to Machine Tool Fixture Design technical field, relates to one part end face holding device fast.
Background technology
Adding in process at the machine of part, need to position part and compress, compress position generally at the upper surface of part, in order to ensure that part can effectively recline locating surface, needs to hold out against the side of part, enabling part and locating surface by real.Traditional compression mode adopts housing screw to be held out against by the effect of support plate, but also need increase a self-locking nut and prevent loosening of screw in process, mounts and dismounts cumbersome, can not realize Fast Installation and the dismounting of part.
Summary of the invention
The object of the invention is: propose a kind of side that can realize part and hold out against fast and the device that can unclamp fast.
Technical scheme of the present invention is: a kind of holding device, this device comprises latch 1, support plate 2, housing screw 3, latch 1 is horizontally through the pilot hole of support plate 2, housing screw 3 passes vertically through support plate 2, the head of screw of housing screw 3 falls in the groove on latch 1, from latch 1 hold out against end, described groove is excessively helicla flute from level trough.
Latch 1 left-hand seat pommel overlaps on the shank contacted with support plate 2 spring 4, and spring 4 one end is stuck on support plate 2 in installing hole, and one end is stuck on latch 1 handle.
Advantage of the present invention is: the side that can realize part holds out against and the device that can unclamp fast fast.
Accompanying drawing explanation
Fig. 1 is a kind of holding device working state figure of the utility model;
Wherein, 1 is latch, and 2 is support plates, and 3 is housing screws, and 4 is springs, and 5 is workpiece.
Detailed description of the invention
Below the utility model is described in further details.
A kind of holding device, this device comprises latch 1, support plate 2, housing screw 3, latch 1 is horizontally through the pilot hole of support plate 2, housing screw 3 passes vertically through support plate 2, the head of screw of housing screw 3 falls in the groove on latch 1, from latch 1 hold out against end, described groove is excessively helicla flute from level trough.
Latch 1 left-hand seat pommel overlaps on the shank contacted with support plate 2 spring 4, and spring 4 one end is stuck on support plate 2 in installing hole, and one end is stuck on latch 1 handle.
The course of work of the present utility model is as follows:
By latch 1 by the pilot hole on support plate 2, and make groove on latch 1 by housing screw 3, under the guiding of support plate 2 hole and housing screw 3 head of screw, level trough on latch 1 and helicla flute can control the direction of motion and the rotation of latch 1, and then realize latch 1 and can be pressed on workpiece 5.Be arranged on spring 4 on support plate 2 and latch 1 along with moving horizontally of latch 1 can to the power of latch 1 one levels, latch 1 can effectively be reclined workpiece 5.During dismounting, spring 4 also plays and returns latch 1 and act on.
