Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of scribing devices, and particularly relates to a chemical milling device. Background Technology
[0002] Chemical milling (CMM) is a machining technique that uses chemical solutions to mill the exposed surfaces of parts. It's a process that utilizes the principle of chemical corrosion to machine parts. Before CMM, the parts need to be cleaned and degreased, and a peelable CMM protective coating that resists the corrosive solution is applied to the surface. Then, a CMM template is used to position and shape the parts. The CMM protective coating is then removed from the areas to be milled. Finally, the parts are immersed in the corrosive solution to corrode the exposed surfaces, resulting in parts with the desired shape, dimensions, and precision.
[0003] Knowing the arc to determine the center position and then engraving the shape, chemical milling tools are mainly used for engraving circular areas in chemical milling. Currently, for flat and skin-like parts in circular chemical milling areas, workers generally carve two arcs according to the template shape, then connect and carve the line connecting the two ends of the arc, measure its length with a ruler, carve the perpendicular bisector, and determine the center by the intersection of the two perpendicular bisectors. This method of determining the center is complex, has large errors, and is inefficient. Utility Model Content

[0029] Three slide rails are axially connected to the main rod, ensuring that the slide rails can rotate freely around the main rod. The carving knife and two fixed rods are connected to the slider and the fixed rods are fixed by locking bolts. The pulley and slider can slide freely on the slide rails. The specific steps of the method are as follows:
[0030] Step 1: Align the tip of the fixing rod with the outer contour line of the engraved and milled adhesive, and tighten the locking bolt to fix the slider position.
[0031] Step two: The center pin is pressed out by the main shaft and secured by the locking bolt, thus determining the center. Then, the fixing rod is retracted to prevent it from affecting the engraving knife.
[0032] Step 3: Align the engraving tool with the outer contour of the chemical milling adhesive and engrave the shape. The slide rail has markings, which can also be used to determine the radius.
[0033] The locking device bolts 3 are respectively installed on the main rod 1, the slider 8, and the pulley 5. This locking device is used to lock and fix the snap pin 2, preventing it from sliding. The locking device is a screw type, providing excellent stability.
