A steering knuckle marking machine

Abstract

The invention belongs to the field of production and manufacture of auto parts, and specifically discloses a steering knuckle marking machine, which includes a marking machine body, a printing head and an ink cartridge. The printing head is fixedly connected with a push rod, and the push rod is hinged with a pawl , there is a rotating shaft inside the ink cartridge, and the marking machine body above the ink cartridge is slidably connected with a ratchet bar that engages with the pawl. degree, the ratchet rack is provided with a rotation drive mechanism for driving the rotation of the shaft; the outer circle of the shaft is connected with several fan-shaped paddles, the rotation axis of the fan-shaped paddles extends radially along the shaft, and several fan-shaped paddles along the The rotating shafts are distributed circumferentially and can be spliced ​​into circular plates. The rotating shaft is provided with a paddle adjusting mechanism for adjusting the angle of the fan-shaped paddles. The edges of the fan-shaped paddles are attached to the inner wall of the ink box. The invention can prevent ink delamination, keep the pressure inside the ink box constant, and the printing quality is good.

Description

technical field [0001] The invention relates to the field of auto parts production and manufacturing, in particular to a steering knuckle marking machine. Background technique [0002] Automobile steering knuckle, also known as "horn", is one of the important parts in the automobile steering axle, which can make the car drive stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car. When the car is running, it bears variable impact loads, so it is required to have high strength. [0003] Before the steering knuckle leaves the factory, it is necessary to mark the steering knuckle, and print the logo of the enterprise on its surface to prove that it is a product of a certain enterprise. At present, when printing the logo, the worker often puts the steering knuckle on the marking machine Marking at the marking hea...

Problems solved by technology

[0003] Before the steering knuckle leaves the factory, it is necessary to mark the steering knuckle, and print the logo of the enterprise on its surface to prove that it is a product of a certain enterprise. At present, when printing the logo, the worker often puts the steering knuckle on the marking machine Marking at the marking head of the marking machine, because the ink cartridge of the marking machine is stationary, the ink in the ink cartridge is prone to delamination when it is standing still, resulting in different shades of the printed logo and poor quality of the printed mark

And the ink in the ink box needs to maintain a certain pressure so that the ink can reach the print head smoothly, but as the amount of ink in the ink box decreases, the liquid pressure in the ink box gradually decreases, which will lead to the thickness of the printed logo line different
