It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0022] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0023] The following will further illustrate the present utility model in conjunction with the attached Figures 1 - 3 drawings.

[0024] To solve the problems existing in the background art, the present application proposes the following technical solution: a laser engraving device for metal processing.

[0025] In the specific technical solution, it includes a processing frame 1 and a steering component 2. The middle position of the processing frame 1 is hollow, and the hollow part is mainly below the engraving. A waste collection box is placed below the hollow part. During engraving, the carved dust falls through the hollow part into the waste collection box. And when rotating the processing piece, the hollow setting will not hinder the processing piece. The steering component 2 is arranged above the processing frame 1, and the steering component 2 is used to change the processing surface of the metal processing piece;

[0026] The steering component 2 includes a steering column 201. An inner groove 202 is opened inside the steering column 201. Four through grooves 203 are opened on the outside of the steering column 201. The four through grooves 203 are equidistantly arranged. A sliding frame 204 is slidably installed inside the inner groove 202. The middle part of the sliding frame 204 is circular and fits and slides inside the inner groove 202. Four protrusions are arranged on the circular edge, and the protrusion parts slide in the corresponding through grooves 203 respectively. Four insertion columns 205 are fixed on one side of the sliding frame 204. And on the other side of the sliding frame 204, a spring 206 and a connecting column 207 are respectively fixed. One end of the connecting column 207 extends to the outside of the steering column 201, and an adjusting handle 208 is fixed at the end of the connecting column 207 extending to the outside of the steering column 201. A boosting rod 209 is fixed on one side of the steering column 201.

[0027] A positioning component 3 is arranged above the processing frame 1. The positioning component 3 is used to fix the metal processing piece. The positioning component 3 includes two L-shaped support plates 301. The supporting surfaces below the two L-shaped support plates 301 are used as the bottom support points when positioning the processing piece. On the opposite sides of the two L-shaped support plates 301, two cylinders 302 are fixed through support plates respectively. The cylinders 302 are electrically connected to an external control system through the prior art. Two limiting grooves 303 are opened on the opposite sides of the two L-shaped support plates 301 respectively. A clamping plate 304 slides between the two limiting grooves 303. One end of the telescopic rod of the cylinder 302 is fixed on the clamping plate 304 and is used to drive the clamping plate 304 to lift and lower. A plurality of suction cups 305 are fixed below the clamping plate 304.

[0028] Place the processing piece between the two L-shaped support plates 301. Push the clamping plate 304 downward through the cylinder 302 until the clamping plate 304 clamps the processing piece, and press the suction cups 305 against and adsorb on the upper surface of the processing piece. When the steering component 2 rotates the positioning component 3 later, it can prevent the processing piece from slipping between the clamping plate 304 and the L-shaped support plates 301.

[0029] There are two grooves 4 opened above the processing frame 1. A bidirectional lead screw 5 rotates inside one of the grooves 4. One end of the bidirectional lead screw 5 penetrates and extends to one side of the processing frame 1, and the penetration part is rotatably connected. A traction rod 6 is fixed inside the other groove 4. A motor 7 is fixed on one side of the processing frame 1. The motor 7 is electrically connected to an external control system through the prior art, and one end of the output shaft is fixed to one end of the bidirectional lead screw 5 for driving the bidirectional lead screw 5 to rotate. Two moving plates 8 are threadedly installed on the outside of the bidirectional lead screw 5. Both of the two moving plates 8 slide on the traction rod 6. According to the size of the workpiece to be processed, the motor 7 is started. The motor 7 drives the bidirectional lead screw 5 to rotate, so that the two moving plates 8 move relatively, changing the distance between the two L-shaped support plates 301 to make it suitable for supporting workpieces of different sizes.

[0030] Two L-shaped support plates 301 are respectively fixed on the opposite sides of the two moving plates 8. The steering column 201 is rotatably installed inside one of the moving plates 8 and is fixed to one side of the L-shaped support plate 301 close to it. Four jacks 9 are opened on one side of this moving plate 8. Both the jacks 9 and the plug posts 205 are conical, which is convenient for the plug posts 205 to quickly slide into the jacks 9 along the conical holes after one end of the plug posts 205 corresponds to the jacks 9. One end of the steering column 201 is fixed to one side of the L-shaped support plate 301.

[0031] Guide grooves 10 are opened on both sides of the processing frame 1. A driving frame 11 slides between the two guide grooves 10. The driving frame 11 is driven by a driving track to realize the forward and backward movement of the laser engraving head 13. A lifting frame 12 is fixed in front of the driving frame 11. A left-right driving mechanism is arranged on the driving frame 11 for changing the position of the lifting frame 12 in the left-right direction. The lifting frame 12 can be an oil cylinder. A laser engraving head 13 is fixed below the lifting frame 12. The laser engraving head 13 realizes the movement on the X-axis, Y-axis and Z-axis under the drive of the driving frame 11 and the lifting frame 12.

[0032] For those skilled in the art to fully understand the technical solution, the following is an overall overview of this application:

[0033] During use, after the workpiece is fixed by the positioning component 3, the laser engraving head 13 engraves on the workpiece under the drive of the drive frame 11 and the lifting frame 12. After one side of engraving is completed, the adjusting handle 208 and the assisting rod 209 can be directly held, and the adjusting handle 208 is pulled towards the assisting rod 209. The adjusting handle 208 then pulls the sliding frame 204 through the connecting column 207 to squeeze the spring 206 until the inserting column 205 disengages from the jack 9. According to the position of the engraving surface, the tightly held assisting rod 209 and the adjusting handle 208 are rotated until the positioning component 3 drives the workpiece to rotate the engraving surface to the corresponding orientation of the laser engraving head 13. The adjusting handle 208 is released, and the elastic force of the spring 206 pushes the sliding frame 204 and the inserting column 205 until the inserting column 205 slides into the jack 9 along the inclined inner wall thereof, and then the orientation of the positioning component 3 can be fixed. The conversion of the engraving surface of the workpiece is convenient and fast, effectively improving the engraving efficiency of the device.
