Technical Field

[0001] The utility model relates to the technical field of laser engraving machines, and in particular to an adjustable positioning and fixing device for a passenger car VIN code engraving machine. Background Art

[0002] Laser engraving machines use laser beams to mark on the surfaces of various materials. The marking effect is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and texts. Laser engraving machines are mainly divided into CO2 laser engraving machines, semiconductor laser engraving machines, fiber laser engraving machines and YAG laser engraving machines. Laser engraving machines are mainly used in some occasions that require more sophisticated and higher precision, such as electronic components, integrated circuits, electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials and PVC pipes, etc.

[0003] The vehicle VIN code is directly engraved on the metal surface of the passenger seat crossbeam of the vehicle body by the laser beam of the laser engraving machine. Due to the slender structure of the crossbeam and the small supporting area, the laser engraving machine placed directly on the crossbeam will be unstable and even fall over, so it is necessary to design a positioning, supporting and fastening device for the laser engraving machine. During the research and development and trial production stage of automobiles, the output of trial vehicles is small and the models are many. The size and structure of the seat crossbeams of different models are different. However, the existing special tooling is only suitable for one model and cannot be adjusted. It cannot be quickly changed on multiple models, resulting in the laser engraving machine being unable to adjust the laser engraving position according to the position of the model seat, which affects the use effect of the laser engraving machine. It is urgent to design an adjustable VIN code engraving machine positioning and fixing device. Utility Model Content

[0020] The following is combined with Figures 1 to 4 The present invention will be further described in detail with reference to the specific implementation methods. To make the purpose, technical solutions and advantages of the implementation methods clearer, the technical solutions in the implementation methods will be clearly and completely described in combination with the drawings in the implementation methods of the present invention. The specific implementation methods described here are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] As attached Figure 1 As shown in the figure, an adjustable positioning and fixing device for a passenger car VIN code engraving machine comprises: a main connecting plate 1, a supporting leg 2, a buckle pad 3, a transition plate 4, a bracket 5, a positioning pin 6, and a hand screw 7. A rectangular through hole is set at the center of the main connecting plate 1, and a laser engraving is performed on the co-pilot seat crossbeam C of the vehicle body through the rectangular through hole. A supporting leg 2 is set at the bottom of the main connecting plate 1, as shown in the attached figure. Figure 3As shown, the two identical legs 2 are symmetrically arranged along the Y-axis of the main connecting plate 1, and the two identical legs 2 are bolted to the main connecting plate 1. The legs 2 are L-shaped, and the main connecting plate 1 is placed on the upper surface of the co-pilot seat cross beam C of the vehicle body through the legs 2. The oblique sides of the legs 2 are close to one side of the co-pilot seat cross beam C of the vehicle body, ensuring that the position and direction of the vehicle VIN code are accurately engraved. Snap-on pads 3 are respectively arranged on the front and rear sides of the main connecting plate 1, and the snap-on pads 3 are threadedly connected to the main connecting plate 1. There are 4 snap-on pads 3, which are fixed at the four corners of the main connecting plate 1 and are used to connect the quick clamping device of the laser engraving machine. Transition plates 4 are respectively arranged on the left and right sides of the main connecting plate 1, and the transition plates 4 are L-shaped bending plates. The main connecting plate 1 and the transition plate 4 are respectively provided with long holes in the X and Y directions, wherein the horizontal and vertical surfaces of the bending plate are provided with long holes, wherein the long holes provided on the horizontal surface are perpendicular to the direction of the long holes on the main connecting plate 1, and the relative positions of the transition plate 4 and the main connecting plate 1 can be adjusted in the X and Y directions, and the first bolt 8 and the second bolt 9 penetrate through the long holes on the transition plate 4 and the main connecting plate 1, and are fastened with the first nut 10 and the second nut 11, as shown in the attached Figure 4 As shown, the transition plate 4 is threadedly connected with the bracket 5, and the bracket 5 is an L-shaped bent plate. The upper plane of the bracket 5 is fitted with the upper surface of the passenger seat cross beam C of the vehicle body. The vertical surface of the bracket 5 is provided with a long strip hole that intersects with the long strip hole on the transition plate 4, so that the relative height and angle of the bracket 5 and the transition plate 4 can be adjusted.
