Abstract
The invention relates to a connecting rod mechanism of a numerical control cutting machine, which comprises a base body and five parallelogram connecting rod mechanisms arranged on the base body, wherein a motor driving device is arranged at the front end of each connecting rod, and a cutting gun mechanism is arranged at the tail end of each connecting rod. The cutting torch is characterized in that all connecting rods are arranged in a layered mode, the fact that the rod sets do not conflict when the connecting rods rotate at any angle is achieved, and when the cutting torch moves along with the connecting rod mechanism, the position of a working point at the tail end of the cutting torch can be fixed. Therefore, the mechanism only changes the attitude of the cutting gun without changing the position of the working point of the cutting gun when rotating, and solves the problem of working point deviation when the attitude of the rotating shaft of the traditional multi-shaft cutting machine is changed.

Technical Field
The invention relates to the field of numerical control cutting machines, in particular to a connecting rod mechanism of a numerical control cutting machine.
Background
The existing numerical control cutting machine relates to multi-axis three-dimensional cutting, particularly when a groove is cut, a cutting gun needs to rotate by a certain angle, so that a working point of the cutting gun can deviate, the offset needs to be calculated and compensated through a numerical control system, meanwhile, the working stroke of compensation quantity needs to be specially set during equipment design, the equipment cost is increased, and the production efficiency is reduced. A quadrilateral link mechanism in a horizontal multi-axis cutting machine can solve the problem, but the rotation angle of the quadrilateral link mechanism is limited, self-interference can be caused when the rotation angle exceeds the limit, and the posture that a gun head is parallel to a base body cannot be realized, so that the quadrilateral link mechanism can only be used in the horizontal cutting machine. The existing solution in the field of vertical multi-axis cutting is that a vertical rotating mechanism of an infinite rotary head has the defects of being large in structure and large in motion inertia, and also generating the problems of increasing cost and reducing efficiency.

In order to solve the defects in the prior art, the invention provides the connecting rod mechanism of the numerical control cutting machine, which can simply and conveniently realize the infinite rotation of the vertically-installed connecting rod mechanism according to a Cartesian coordinate system, is light and portable as a whole and reduces the motion inertia introduced to the whole motion mechanism.
The technical scheme adopted by the invention is as follows:
the motor driving device drives the quadrilateral connecting rod mechanism on the base body, the mechanism has only one degree of freedom and a determined motion track, and the working point of the cutting gun is fixed when the cutting gun rotates.
The invention has the beneficial effects that: simple structure, the lightweight realizes that the burning torch is fixed when rotatory under the prerequisite of inertia burden is not brought to the system, makes multiaxis numerical control cutting machine needn't design pendulum rifle compensation stroke again, and because of need not walk the compensation stroke, has reduced the length of whole cutting orbit, has improved cutting work efficiency.
