Technical Field
The invention relates to the technical field of positioning devices for processing workpieces by using laser beams, in particular to a laser cutting positioning tool.
Background
Laser cutting is a cutting method which is used more frequently in cutting automobile panels. When cutting, the automobile panel needs to be positioned to ensure the accuracy of the cutting position. Generally, a positioning tool is adopted in positioning, and because the shape of the automobile covering part is irregular, each covering part needs to use a corresponding positioning tool. Because the automobile covering part is generally larger in size, the positioning tool is correspondingly larger in manufacturing in order to ensure the positioning precision and the cutting stability of the automobile covering part. When different types of automobile covering parts are cut, different positioning tools are needed, so that enterprises need to store a large number of positioning tools, the tool investment cost of the enterprises is high, the tools are large in size, and a large amount of production space of the enterprises needs to be occupied; and also inconvenient dismantlement and installation when changing the location frock influence machining efficiency.

The welding positions of the support plate and the connecting plate are arranged at the quarter of the vertical edge of the support plate, so that the stability of the edge of the support plate can be improved by fully utilizing the connecting force of spot welding, and the lower half parts of the crossed positions of the two support plates can be subjected to auxiliary fixing.
Further, the top corners of the first supporting plate and the second supporting plate are both rounded. By rounding off corners, the top corners of the first support plate and the second support plate are prevented from scraping the patterned workpiece.
Furthermore, the welding point on the first supporting plate uses the first supporting plate as the mirror image setting of the symmetry plane. The welding points are arranged through the mirror images, so that the deformation influence of temperature stress generated during welding on the first supporting plate can be reduced as much as possible.

After the cutting is completed, when the tool needs to be stored, the bolt on the connecting plate 2 and the fixing plate 1 are disassembled, so that the positioning unit and the fixing plate 1 can be separated, and the positioning unit is conveniently stored. The positioning unit is small in size and mass, and is convenient for workers to detach, install and the like.
Example two: as shown in fig. 2 and 3, the first embodiment is different from the first embodiment only in that: vertical grooves are formed in the vertical edges of the first supporting plate 3, oil storage fiber strips 8 are embedded in the grooves, and the oil storage fiber strips 8 are preferably cotton slivers. The first supporting plate 3 is welded with a driving box 7 made of heat conducting material, the driving box 7 is located on a main track of chip splashing when the workpiece is cut by laser, and the heat conducting material is preferably copper. An oil inlet 72 and an oil outlet 71 are arranged on the drive box 7, one end of the oil inlet 72 facing the inside of the drive box 7 is covered with an oil inlet shifting sheet 11 for preventing oil from flowing out of the drive box 7, the specific oil inlet shifting sheet 11 is a steel shifting sheet, the upper end of the oil inlet shifting sheet 11 is welded with the drive box 7, the oil inlet shifting sheet 11 can swing around a welding point under the self elastic action, oil outside the drive box 7 passes through the oil inlet 72 and pushes the oil inlet shifting sheet 11 to swing to enter the drive box 7, and when the external oil does not push the oil inlet shifting sheet 11, the oil inlet shifting sheet 11 covers the oil inlet 72 under the self elastic action, so that the oil in the drive box 7 is prevented from flowing outwards through the oil inlet 72, and the one-way valve effect is formed. An oil outlet shifting sheet 9 is arranged at the oil outlet 71, the oil outlet shifting sheet 9 is positioned at one side of the oil outlet 71, which is far away from the driving box 7, the material of the oil outlet shifting sheet 9 is the same as that of the oil inlet shifting sheet 11, and only the oil inside the driving box 7 can flow outwards through the oil outlet 71, so that the oil outside the driving box 7 is prevented from entering the driving box 7 through the oil outlet 71. The oil outlet 71 is communicated with the top of the groove to form an oil outlet pipe 6. The welding has oil storage box 5 on first backup pad 3, and oil storage box 5 is located the top of drive box 7, and the upper end of oil storage box 5 is less than the end of producing oil of play oil pipe 6, and the bottom of oil storage box 5 and the oil inlet 72 department intercommunication of drive box 7 have into oil pipe 10.
