Description

Positioning tool for laser marking of electromechanical equipment Technical Field The invention relates to the technical field of positioning, in particular to a positioning tool for laser marking of electromechanical equipment. Background The existing positioning mechanism for the laser marking of the electromechanical equipment generally adopts a simple fixed clamping mode in structural design, the traditional positioning device is usually only provided with a basic clamping seat and a plurality of fixed pressing blocks or bolt fasteners, the electromechanical equipment workpiece to be marked is fixed at a preset position through mechanical pressing force, and then laser marking operation is carried out, however, the fixed mode which simply relies on static mechanical pressing has various technical defects, firstly, the external dimension, the structural shape and the surface characteristic of the electromechanical equipment workpiece are extremely different, the motor shell, the control box body, the sensor assembly, the power distribution cabinet panel and other various types are covered, the external outline of the various workpieces has various forms such as a cylinder shape, a square shape, a special-shaped curved surface and the like, the surface materials comprise different materials such as a metal casting, a sheet metal part, a plastic shell and the like, the clamping surface and the pressing point of the traditional fixed clamping mechanism are usually fixed according to the size of a certain specific workpiece, the lack of flexible adjustment adaptability to different workpiece shapes and sizes leads to too small gap or contact area between the clamping point and the workpiece, vibration and air flow impact generated by high-speed movement of a laser head can be transmitted to the clamped workpiece in the laser marking process, the workpiece is easy to generate tiny displacement or shake in the clamp due to insufficient clamping force or uneven stress, the workpiece position deviation in the marking process directly leads to the fact that laser light spots cannot precisely fall on a preset marking path, quality defects such as dislocation, deformation, line breakage and the like occur in marking patterns, characters or codes, the definition and the identifiability of marking information are seriously affected, and the traditional plane clamping mechanism is more difficult to realize stable and reliable fixation for irregular workpieces with a convex structure on the surface, often need operating personnel to adjust clamping position repeatedly and test marking confirmation many times, not only increased supplementary adjustment time and reduced production efficiency, still aggravated clamping part's wearing and tearing because of frequent loading and unloading clamp operation, single fixed clamping structure still easily leaves indentation or fish tail at work piece clamping position to the local pressure concentration of work piece surface simultaneously, especially to the high-grade electromechanical product of surface spraying treatment or decorative shell, the surface damage that the centre gripping caused belongs to unacceptable quality problem, in addition traditional clamping mechanism often need whole dismantlement change anchor clamps or adjust clamping structure by a wide margin when changing different specification work pieces, the production beat of marking operation of many varieties of little batch electromechanical equipment has been restricted to the adjustment time length of taking a mould. The traditional electromechanical device laser marking positioning mechanism can only fix a workpiece to a single horizontal placing posture for laser marking, the marking surface of the workpiece is limited in a vertical upward fixing direction, a laser head can only vertically irradiate from right above for marking operation, the rigid positioning mode lacking the angle adjusting capability is difficult to meet the diversified process requirements of the actual electromechanical device laser marking, because the positions needing marking on the electromechanical device product are often distributed on a plurality of different sides and surfaces with different angles of the product, for example, a motor shell needs to respectively mark nameplate information, production batch and quality authentication marks on a plurality of positions on the end face, the cylindrical side face and the bottom face, a control box needs to respectively mark operation instructions, warning marks and product parameters on a front panel, the side face and an inclined face, for marking areas on the side surfaces, inclined surfaces, curved surfaces or back surfaces of the workpieces, if the positioning mechanism cannot adjust the posture angle of the workpieces to enable the marking surfaces to face the direction of the laser head, the workpieces must be manually turned over by an operator to be clamped and positio
