[0022] Reference Figure 1-Figure 3A positioning device for surface marking comprises a bottom plate 1, two fixing seats 2 are fixed to the upper surface of the bottom plate 1 by bolts, two fixing columns 7 are welded between the two fixing seats 2, a sliding seat 8 is slidably connected to the outer sides of the two fixing columns 7, a turntable 13 is rotatably connected to the upper surface of the slide seat 8, two connecting seats 16 are fixed to the top of the turntable 13 by bolts, a limiting groove 19 is provided on one side of the two connecting seats 16, a slider 17 is slidably connected in the limiting groove 19, a scribing wheel 15 is rotatably connected between the two sliders 17, a spring 14 is welded to the bottom of the limiting groove 19, and the spring 14 is fixed to the slider 17, and a spring 14 is welded to the bottom of the limiting groove 19, and the spring 14 is fixed to the slider 17, and a spring 14 is welded to the upper surface of the slide seat 8. There is an insertion component for fixing the turntable 13, and a rotating hole is opened on one side of the two fixing seats 2, and a threaded ring 25 is rotatably connected in the rotating hole. A threaded rod 3 is threadedly connected in the threaded ring 25, and a clamping plate 5 is rotatably connected at one end of the threaded rod 3. A telescopic component that enables the clamping plate 5 to move horizontally is provided on one side of the two fixing seats 2, and a fixing component that limits the threaded ring 25 is provided on the other side of the two fixing seats 2. The threaded rod 3 is rotated. At this time, since the threaded ring 25 is fixed and cannot be rotated, the threaded rod 3 will move through the threaded engagement with the threaded ring 25, and the threaded rod 3 will push the clamping plate 5 to move horizontally through the telescopic component and The clamping plates 5 rotate to clamp the workpiece, so that the cylindrical workpiece or the plate workpiece can be fixed. When the plate workpiece is to be marked and positioned, the slide 8 is directly pulled to move along the fixed column 7, and the slide 8 drives the turntable 13 to move, so that the marking wheel 15 moves. During the movement, the marking wheel 15 is in close contact with the plate workpiece under the action of the spring 14, so that the friction between the marking wheel 15 and the plate workpiece causes the marking wheel 15 to rotate during the movement, so that the plate workpiece is marked. When it is necessary to mark a cylindrical workpiece, the plug-in assembly is not The turntable 13 is then fixed and then rotated to rotate the marking wheel 15. After the marking wheel 15 rotates ninety degrees, the turntable 13 is fixed by the plug-in assembly. Then the fixing assembly no longer fixes the threaded ring 25. Then the threaded rod 3 is rotated. At this time, since the clamping plate 5 clamps the cylindrical workpiece, the threaded rod 3 cannot move, so that the threaded rod 3 drives the threaded ring 25 to rotate, and drives the clamped cylindrical workpiece to rotate, so that the marking wheel 15 marks and marks the cylindrical workpiece, thereby realizing marking and positioning of different types of workpieces, thereby improving the application range of the positioning device.

[0023] In the utility model, the plug-in assembly includes a connecting plate 23, the connecting plate 23 is welded to the upper surface of the slide seat 8, a sliding opening is provided on one side of the connecting plate 23, a latch 20 is slidably connected in the sliding opening, two second sockets 24 are provided on the circumferential outer wall of the turntable 13, and the latch 20 is plugged into one of the second sockets 24, and an adsorption assembly for fixing the latch 20 is provided on one side of the connecting plate 23, and the adsorption assembly includes a second magnetic block 22, and the second magnetic block 22 is bonded to one side of the connecting plate 23. The first magnetic block 21 is bonded to the side of the latch 20 close to the second magnetic block 22, and the first magnetic block 21 and the second magnetic block 22 are attracted to each other. The distance between the two second sockets 24 is one-fourth of the circumference of the turntable 13. When the latch 20 is pulled to move, the latch 20 will drive the first magnetic block 21 to move, so that the first magnetic block 21 and the second magnetic block 22 are separated, and the latch 20 and the second socket 24 are separated. At this time, the turntable 13 can be rotated. When the scoring wheel 15 rotates 90 degrees, the latch 20 is inserted into another second socket 24 on the turntable 13 to fix the turntable 13. The fixing assembly includes two support plates 9, which are respectively welded to one side of the two fixing seats 2 in opposite directions. A avoidance opening is opened on one side of the two support plates 9, and a plug rod 10 is slidably connected in the avoidance opening. A first socket 11 is opened on the outer wall of one side of the threaded ring 25, and the plug rod 10 is plugged into the first socket 11. The plug rod 10 is pulled to move, so that the plug rod 10 is disengaged from the first socket 11 on the threaded ring 25, so that the threaded ring 25 is no longer fixed. The telescopic component is two telescopic rods 4, and the two telescopic rods 4 are fixed to one side of the fixing seat 2 close to the clamping plate 5 by bolts. One end of the telescopic part of the two telescopic rods 4 is fixed to the clamping plate 5. The clamping plate 5 will stretch the telescopic rod 4 during the movement, so that the clamping plate 5 moves horizontally. A protective pad is bonded to one side of the clamping plate 5, and the protective pad is equal to the clamping plate 5. The protective pad can prevent the clamping plate 5 from causing damage to the surface of the workpiece.

[0024] Working principle: when in use, the threaded rod 3 is rotated. At this time, since the threaded ring 25 is fixed and cannot be rotated, the threaded rod 3 will move through the threaded engagement with the threaded ring 25, and the threaded rod 3 will push the clamping plate 5 to move and rotate between the clamping plate 5, and the clamping plate 5 will stretch the telescopic rod 4 to make the clamping plate 5 move horizontally, so that the clamping plate 5 clamps the workpiece, so that the cylindrical workpiece or the plate workpiece can be fixed. When the plate workpiece is to be marked and positioned, the slide 8 is directly pulled to move along the fixed column 7, and the slide 8 will drive the turntable 13 to move, so that the marking wheel 15 moves, and the marking wheel 15 will be in close contact with the plate workpiece under the action of the spring 14 during the movement, so that the friction between the marking wheel 15 and the plate workpiece causes the marking wheel 15 to rotate during the movement, so as to mark the plate workpiece. When marking a workpiece, the latch 20 is pulled to move, and the latch 20 will drive the first magnetic block 21 to move, so that the first magnetic block 21 is disengaged from the second magnetic block 22, and the latch 20 is disengaged from the second socket 24, and then the turntable 13 is rotated to rotate the marking wheel 15. After the marking wheel 15 rotates ninety degrees, the latch 20 is inserted into another second socket 24 on the turntable 13 to fix the turntable 13, and then the insertion rod 10 is pulled to move, so that the insertion rod 10 is disengaged from the first socket 11 on the threaded ring 25, and then the threaded rod 3 is rotated. At this time, since the clamping plate 5 clamps the cylindrical workpiece, the threaded rod 3 cannot move, so that the threaded rod 3 drives the threaded ring 25 to rotate, and drives the clamped cylindrical workpiece to rotate, so that the marking wheel 15 marks and marks the cylindrical workpiece, thereby realizing marking and positioning of different types of workpieces, thereby improving the application range of the positioning device.
