Embodiment Construction

[0026] The present invention is specifically described below in conjunction with accompanying drawing,

[0027] Take Figure l-1 to Figure 1-4 The machined part is shown as an example. The part is a molded part, and the margin around the part and the holes in 7 spatial directions on the part need to be processed with high precision by a three-dimensional laser cutting machine. Solve the positioning problem of parts with plate-type high-precision fixture.

[0028] According to the size of the parts, a mutual support structure of one bottom plate and multiple vertical and horizontal support plates is adopted. There are no less than 3 support plates or the spacing is no greater than 100mm. The surface of the support plate is the projection curve projected to the lower surface of the part according to the position of the support plate using UG drawing software. Draw the UG model diagram of the part, and create a bottom plate slightly larger than the part at a position 100mm be...

Abstract

The invention discloses a plate-type high-precision clamp special for laser processing. The plate-type high-precision clamp comprises a base plate and a mutually-supporting structure of a plurality of longitudinal supporting plates and a plurality of transverse supporting plates, and the upper molded surfaces of the longitudinal supporting plates and the upper molded surfaces of the transverse supporting plates are molded by UG cartographic software according to projection curves formed by the fact that the positions of the supporting plates are mapped to the lower surface of a part. Interference fit mutually-inserting assembly structures with back chipping are applied to the longitudinal supporting plates, the transverse supporting plates and the base plate. The plate-type high-precision clamp has the advantages that self designing, laser processing program compiling and laser device self machining can be achieved, the time for completing one clamp is normally shorter than two days, the requirements for rapid updating and upgrading of products, high laser processing efficiency and high flexibility are met, and the manufacturing cost of the clamp is greatly reduced. As the plate-type high-precision clamp is low in manufacturing cost and rapid and convenient to manufacture, high storeroom, management and transport cost required by hundreds of common clamps is saved.

Description

technical field [0001] The invention relates to the field of mechanical processing, more specifically to the special processing specialty of material processing engineering, especially the field of laser processing. Background technique [0002] Laser processing includes laser cutting, laser welding, laser drilling, laser cladding, laser marking, etc. In addition to flat parts and round and square parts with simple shapes, special fixtures are required for high-precision and high-efficiency laser processing of three-dimensional parts. General fixture manufacturing requires turning, milling, drilling, tapping, clamping, assembly and other work to complete, with high cost and long processing cycle, which does not meet the high processing efficiency and high flexibility requirements of rapid product upgrading. Since laser processing is a micro-cutting force processing technology, the processing force can be ignored during the processing, as long as the fixture is sufficient to...
