Owing to adopted technique scheme, lifting device, comprise bottom plate as mounting base, be used to install the upper mounted plate of workpiece retainer parts, first strut and second strut are installed between described upper mounted plate and the described bottom plate, described first strut and second strut are " X " shape arranged crosswise, and the infall of described first strut and second strut is equipped with link pin; The lower end of described first strut is hinged on the described bottom plate by the first strut rotating shaft, the upper end of described first strut is provided with the first strut roller, described upper mounted plate is provided with orienting lug, and the described first strut roller is limited in described going up in the orienting lug and moves; The upper end of described second strut is hinged on the described upper mounted plate, and the lower end of described second strut is provided with the second strut roller, and described bottom plate is provided with down orienting lug, and the described second strut roller is limited in moving in the described orienting lug down; The engine installation that makes described first strut swing is installed on the described bottom plate; First strut and second strut that the utility model is arranged by " X " shape, and realize the lifting of workpiece by the swing that engine installation drives first strut, the less stroke of engine installation can be realized higher lifting, changed the present industry retainer parts have been directly installed on traditional method and a single state on the cylinder, broken away from the drawback of cylinder stroke decision lift height in the conventional practice, modern design, simple in structure, easy to operate, production efficiency is high.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in drawings, lifting device, comprise bottom plate 1 as mounting base, one of bottom plate 1 effect is that lifting device is installed in (for example on the die shoe of mould) on lathe or other equipment, be used to install the upper mounted plate 2 of workpiece retainer parts, first strut 3 and second strut 4 are installed between described upper mounted plate 2 and the described bottom plate 1, described first strut 3 and second strut 4 are " X " shape arranged crosswise, and the infall of described first strut 3 and second strut 4 is equipped with link pin 5; The lower end of described first strut 3 is hinged on the described bottom plate 1 by the first strut rotating shaft 31, the upper end of described first strut 3 is provided with the first strut roller 32, described upper mounted plate 2 is provided with orienting lug 32a, and the described first strut roller 32 is limited in moving in the described orienting lug 32a of going up; The upper end of described second strut 4 is hinged on the described upper mounted plate 2, and the lower end of described second strut 4 is provided with the second strut roller 42, and described bottom plate 1 is provided with down orienting lug 42a, and the described second strut roller 42 is limited in moving in the described orienting lug 42a down; The engine installation that makes 3 swings of described first strut is installed on the described bottom plate 1.
