Problems solved by technology
Because the circuit boards have different sizes and thicknesses, the positioning clamps on some fixtures can be adjusted to suit the size or thickness of the circuit boards. There are generally four positioning clamps on the fixtures for clamping the circuit boards. The four sides of the structure, but this kind of structure can only be positioned at the beginning. When the positioning is good, it will be more troublesome to fine-tune

The invention discloses a structurally optimized circuit board cutting positioning fixture. Uprights are fixed on the four corners of a bottom plate, the top ends of the uprights are fixed on a top plate, a rectangular discharge hole is formed in the center of the top plate, a plurality of guide ways are fixed on the top plate around the discharge hole, sliders are inserted in the guide ways, positioning bases are fixed on the sliders, each positioning base comprises a bearing plate fixed on one slider, vertical rear plates are fixed on both sides of the rear end of the bearing plate, and a horizontal supporting plate is fixed at the top ends of the rear plates; a lower ball is embedded in the front end of the bearing plate, a pressing plate is arranged over the lower ball, an upper ball is embedded in the lower end surface of the pressing plate, a plurality of vertical guide posts are fixed on the upper end surface of the pressing plate, the upper ends of the guide posts run through the supporting plate and are fixed on a connecting plate, compressed springs sleeve the guide posts, and both ends of each compressed spring respectively abut against the pressing plate and the supporting plate. The structure of the structurally optimized circuit board cutting positioning fixture is simple, and the structurally optimized circuit board cutting positioning fixture can be finely adjusted again after initial positioning, realizing the high-precision positioning of a circuit board and guaranteeing the quality of laser cutting.
Description
[0001] Technical field: [0002] The invention relates to the technical field of laser processing equipment, in particular to a circuit board cutting and positioning fixture with an optimized structure. [0003] Background technique: [0004] Laser cutting is currently a commonly used thermal processing method for some sheets. When the sheet is cut under the laser generator, it is often necessary to position and clamp the sheet through a fixture. For example, the laser cutting of some circuit boards is no exception. Because the circuit boards have different sizes and thicknesses, the positioning clamps on some fixtures can be adjusted to suit the size or thickness of the circuit boards. There are generally four positioning clamps on the fixtures for clamping the circuit boards. The four sides of the structure, but this kind of structure can only be positioned at the beginning. When the positioning is good, it is more troublesome to fine-tune it. [0005] Invention content: ...
