Abstract
The utility model discloses a device driven by a ball screw pair. The device comprises a positioning pin fixedly installed and two scissor bodies which are hinged together through the positioning pin. The device further comprises the ball screw pair, a driving assembly and a guide assembly, the ball screw pair is provided with a lead screw and a nut, the driving assembly is movably connected with the lead screw so as to drive the lead screw to rotate, the nut is installed on the lead screw in a sleeved mode, the nut is in slip fit with the guide assembly, two driving pins are installed on the nut in an inserting mode, the two driving pins can rotate relative to the radial direction of the nut, the scissor bodies correspond to the driving pins one to one, and the tail ends of the scissor bodies are hinged to the corresponding driving pins. The device can achieve automatic shearing of scissors and avoid the phenomenon that the scissors shake vertically when closed, and is long in service life and high in carrying capacity.
Description
Technical field
The utility model relates to a kind of device driving with ball screw assembly.
Background technology
At present, the scissors of prior art mostly adopts people's hand operated, in the time need to cutting out large piece or harder object, adopts people's hand operated to be difficult to cut out, and in the time of the scissors closure of this structure, there will be up and down shake, and service life is not long.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, a kind of device driving with ball screw assembly, is provided, and it can realize the automatic shearing of scissors, and the phenomenon of having avoided scissors to shake up and down in closed, long service life, bearing capacity is strong.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of device driving with ball screw assembly, comprise hard-wired alignment pin and pass through two hinged scissor bodies of alignment pin, also comprise ball screw assembly, driven unit and guidance set, ball screw assembly, has leading screw and nut, driven unit and leading screw are flexibly connected so that it drives leading screw rotation, nut sleeve is contained on leading screw, and slide nut fits on guidance set, on nut, be fitted with two drive pins, and two drive pins moving radially of nut relatively, described scissor body and drive pin are corresponding one by one, and the tail end of scissor body is hinged on corresponding drive pin.
Adopt after technique scheme, when driven unit action, when making leading screw rotation, nut is axially moving with respect to leading screw forward or backward under the effect of guidance set, thereby the edge of a knife that drives two scissor bodies opens or be closed, thereby realize the automatic shearing of scissors, and the phenomenon of having avoided scissors to shake up and down in closed, long service life, bearing capacity is strong.
Brief description of the drawings
Fig. 1 is the structural representation of the device driving with ball screw assembly, of the present utility model.
Detailed description of the invention
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below.
As shown in Figure 1, a kind of device driving with ball screw assembly, comprise hard-wired alignment pin 1 and pass through two hinged scissor bodies 2 of alignment pin 1, also comprise ball screw assembly, driven unit and guidance set, ball screw assembly, has leading screw 3 and nut 4, driven unit and leading screw 3 are flexibly connected so that it drives leading screw 3 to rotate, nut 4 is sleeved on leading screw 3, and nut 4 is sliding to be fitted on guidance set, on nut 4, be fitted with two drive pins 5, and two drive pins 5 moving radially of nut 4 relatively, scissor body 2 and drive pin 5 are corresponding one by one, and the tail end of scissor body 2 is hinged on corresponding drive pin 5.
Operation principle of the present utility model is as follows:
When driven unit action, when leading screw 3 is rotated, nut 4 is axially moving with respect to leading screw 3 forward or backward under the effect of guidance set, thereby the edge of a knife that drives two scissor bodies 2 opens or is closed, thereby realize the automatic shearing of scissors, and the phenomenon of having avoided scissors to shake up and down in closed, long service life, bearing capacity is strong.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
