Description
Technical Field
The utility model relates to the field of wire harness machines, in particular to a driving structure of a wire harness machine.
Background
When the wire harness machine is used for welding, the main welding rod needs to move up and down, the size of the wire harness machine is small, the air cylinder for driving the main welding rod to move is not large in space design, the welding pressure required by the wire harness machine is generally completed by the air cylinder with the cylinder diameter of 100mm, and the traditional solution is that the air cylinder with the cylinder diameter of 50mm is used for driving in a lever amplification mode. The scheme of realization is that the cylinder is placed horizontally, and the cylinder stroke is increased to obtain larger welding pressure. Referring to fig. 1, in the conventional method, a main welding rod 1 is connected with an oblique waist-shaped hole of a lever device 3 through a driving shaft, the lever device 3 is connected with a piston rod horizontally arranged in a cylinder 2, the cylinder 2 drives the lever device 3 to move rightwards during operation, and the lever device 3 drives the main welding rod 1 to move downwards through the oblique waist-shaped hole; the inclination of the inclined waist-shaped hole in the middle of the lever device 3 is less than 45 degrees, so that the lever amplification function is realized; this structure lever means 3 need pass main welding rod 1 completely for the size on both sides is thinner about main welding rod 1, and processing yielding makes the size difficult to guarantee, thereby presss from both sides the line when leading to the welding.
SUMMERY OF THE UTILITY MODEL
