Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to shown in Fig. 1 to Fig. 3, the preferred embodiment of the utility model clamp body bottom and top feed system, comprises the first servomotor 1, shaft coupling 2, rolling lead screw nut assembly 3, clamp body assembly 4 and frame 5.This clamp body bottom and top feed system is arranged on respectively the both sides of frame 5 individually.
The first servomotor 1 connects with rolling lead screw nut assembly 3 by shaft coupling 2, and the first servomotor 1 is fixed on the top of frame 5.Rolling lead screw nut assembly 3 comprises the rolling lead screw 31 and the nut 32 that cooperatively interact, and rolling lead screw 31 one end are connected with shaft coupling 2, and its other end is connected with clamp body assembly 4, and nut 32 is arranged in frame 5.The first servomotor 1 drives clamp body assembly 4 to carry out bottom and top feed motion by rolling lead screw nut assembly 3.
In frame 5, be also provided with line slideway 6, clamp body assembly 4 can move on line slideway 6.In the present embodiment, line slideway 6 is accurate straight ball-guide, ensures stability and the accuracy of clamp body assembly 4 bottom and top feed motions.On rolling lead screw 31, be also socketed with bearing 33, stability when raising rolling lead screw 31 rotates.Bearing 33 is arranged in frame 5.
Clamp body assembly 4 comprises clamp body 41, clamp body fixed head 42, clamp body clamping cylinder 43 and worm and gear assembly (not shown), and clamp body fixed head 42, clamp body clamping cylinder 43 and worm and gear assembly are separately fixed on clamp body 41.Be provided with thimble 44 in the bottom of clamp body 41, workpiece is fixed on the end of thimble 44.
