Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, specifically a positioning mechanism for laser marking of magnetic rings. Background Technology

[0002] Laser marking technology is one of the largest applications of laser processing. Laser marking uses a high-energy-density laser to locally irradiate a workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thus leaving a permanent mark. Magnetic rings are ring-shaped magnetic conductors made of ferrite material and are key components in electronic circuits used to suppress high-frequency electromagnetic interference. Magnetic rings are often used for anti-counterfeiting purposes using laser marking.

[0003] Existing positioning mechanisms for laser marking of magnetic rings are complex in structure, inconvenient to maintain, and pose safety hazards because the installation and removal of the magnetic ring are performed directly below the laser marker. Therefore, those skilled in the art have provided a positioning mechanism for laser marking of magnetic rings to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a positioning mechanism for laser marking of magnetic rings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning mechanism for laser marking of magnetic rings includes a base, a fixed clamping block, and a movable clamping block. A fixed mounting plate is vertically welded to one side of the top of the base. A mounting post is threadedly connected to the top of the side of the fixed mounting plate. A conical fixed clamping block is positioned at the top of the mounting post. A ball screw drive mechanism is bolted to the other side of the top of the base. A connecting plate is bolted to the top of the slider of the ball screw drive mechanism. A movable mounting plate is vertically welded to one side of the top of the connecting plate. The movable mounting plate has a conical fixed clamping block positioned at the top of its side. The base is connected to a positioning rod via a threaded connection. The positioning rod is coaxial with the mounting column. A limit ring is welded onto the positioning rod. A conical movable clamping block is slidably connected to the positioning rod between the limit ring and the movable mounting plate. A spring is provided between the movable clamping block and the movable mounting plate. A magnetic ring to be processed is provided between the fixed clamping block and the movable clamping block. Columns are vertically welded to the four corners of the top of the base. A top mounting plate is fixedly connected to the top of the columns by bolts. A laser marking device is provided at the bottom of the top mounting plate.

[0007] As a further embodiment of this utility model: the tail of the fixing block is provided with a connecting internal thread, the mounting post is threadedly connected to the fixing block, and the top of the mounting post and the center position of the fixing block are provided with a positioning hole.

[0008] As a further improvement of this utility model: a pressure sensor is provided at the bottom of the round hole at the top of the mounting column, the mounting column is slidably connected to the positioning rod, and a pressure relief hole is provided at the bottom of the round hole at the top of the mounting column.

[0009] As a further improvement of this utility model: a sliding hole is provided at the center of the movable clamping block, and the positioning rod is slidably connected to the sliding hole.

[0010] As a further improvement of this utility model: a first reinforcing rib is welded between the inner ends of the fixed mounting plate and the base, and a second reinforcing rib is welded between the movable mounting plate and the connecting plate.

[0011] As a further improvement of this utility model, the limiting ring has a relatively large width to provide auxiliary support for the magnetic ring to be processed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, a positioning rod is threadedly connected to the top side of the movable mounting plate. The positioning rod and the mounting column are coaxial. When the magnetic ring to be clamped is clamped and fixed, the ball screw transmission mechanism drives the slider to move towards the fixed mounting plate, so that the positioning rod passes through the fixed clamping block and slides with the mounting column, ensuring the coaxiality of the movable clamping block and the fixed clamping block. The spring pushes the movable clamping block and the fixed clamping block to fix the magnetic ring to be clamped together, improving the accuracy and stability of the fixation. The structure is simple and reliable and easy to use.

[0014] 2. In this utility model, by welding a limiting ring onto the positioning rod, the limiting ring limits the movement of the movable clamping block to prevent it from slipping off. The limiting ring also limits the displacement of the positioning rod to prevent excessive movement of the positioning rod from damaging the pressure sensor located inside the mounting column. The wider limiting ring also supports the magnetic ring to be clamped, making the downward angle of the entrance of the magnetic ring to be clamped smaller, thus improving the smoothness of contact between the top of the fixed clamping block and the magnetic ring to be clamped.

A fixed mounting plate 2 is vertically welded to one side of the top of the base 1. A mounting post 6 is threadedly connected to the top of the side of the fixed mounting plate 2. A conical fixed clamping block 7 is provided on the top of the mounting post 6. A ball screw transmission mechanism 8 is bolted to the other side of the top of the base 1. A connecting plate 9 is bolted to the top of the slider 19 of the ball screw transmission mechanism 8. A movable mounting plate 10 is vertically welded to one side of the top of the connecting plate 9. A positioning insert 12 is threadedly connected to the top of the side of the movable mounting plate 10. Positioning rod 12 is coaxial with mounting column 6. A limiting ring 18 is welded on positioning rod 12. A conical movable clamping block 14 is slidably connected between positioning rod 12 and the limiting ring 18 and movable mounting plate 10. A spring 13 is provided between movable clamping block 14 and movable mounting plate 10. A magnetic ring 15 to be processed is provided between fixed clamping block 7 and movable clamping block 14. Columns 4 are vertically welded to the four corners of the top of base 1. A top mounting plate 5 is fixedly connected to the top of column 4 by bolts. A laser marking device 16 is provided at the bottom of top mounting plate 5. Fixed clamping block 7 and movable clamping block 14 are used together to clamp firmly. The installation and removal of the magnetic ring to be clamped are both carried out on the side of the marking machine, making it safer to use.

[0024] The fixed clamp 7 has an internal thread 20 at its tail. The mounting post 6 and the fixed clamp 7 are connected by a thread. The top of the mounting post 6 and the center of the fixed clamp 7 are provided with a positioning hole. The fixed clamp 7 is easy to disassemble and install, and easy to maintain.

[0025] Among them, a pressure sensor 17 is provided at the bottom of the round hole at the top of the mounting column 6. The mounting column 6 is slidably connected to the positioning rod 12. A pressure relief hole is provided at the bottom of the round hole at the top of the mounting column 6. The laser marking device 16 is started by the pressure sensor 17, which saves the starting steps and is simple and reliable to use.

[0026] The movable clamping block 14 has a sliding hole 21 at its center. The positioning rod 12 is slidably connected to the sliding hole 21. The movable clamping block 14 is installed from the threaded end of the positioning rod 12, making disassembly and maintenance convenient.

[0027] Among them, the inner ends of the fixed mounting plate 2 are welded to the base 1 with a first reinforcing rib 3, and the movable mounting plate 10 is welded to the connecting plate 9 with a second reinforcing rib 11 to improve the welding strength between the fixed mounting plate 2 and the movable mounting plate 10.

[0028] The limiting ring 18 has a larger width, which provides auxiliary support for the magnetic ring 15 to be processed and improves the smoothness of the clamping process.

[0029] The working principle of this utility model is as follows: First, the magnetic ring to be clamped is installed on the positioning rod 12. At this time, the movable mounting plate 10 is located on one side of the base 1 along with the slider 19, avoiding the position below the laser marking device 16. The positioning rod 12 is inserted into the center of the magnetic ring to be clamped. At this time, the movable clamping block 14 is in contact with the limiting ring 18 under the action of the spring 13. One end of the magnetic ring to be clamped is in contact with the movable clamping block 14, the middle part of the magnetic ring to be clamped is supported by the limiting ring 18, and the other side of the magnetic ring to be clamped is suspended and does not contact the positioning rod 12. Next, the ball bearing is activated. The ball screw drive mechanism 8, through its slider 19, drives the movable mounting plate 10 towards the fixed mounting plate 2 via the connecting plate 9, until the limiting ring 18 is in contact with the top of the fixed clamping block 7. The spring 13 is compressed, and the magnetic ring to be clamped is held and fixed by the conical structure of the fixed clamping block 7 and the movable clamping block 14, and is concentric with the positioning rod 12. At this time, the positioning rod 12 is inserted into the positioning hole at the top of the mounting column 6, triggering the pressure sensor 17 to start the laser marking machine 16, marking the top side of the positioned magnetic ring. The clamping is secure, the positioning accuracy is high, and it is easy to use. After marking, the ball screw drive mechanism 8 operates, causing the magnetic ring to be clamped to leave the lower position of the laser marking machine along with the positioning rod 12 and the movable clamping block 14. The magnetic ring can then be disassembled. The installation and disassembly of the magnetic ring are performed by the operator on the side of the laser marking machine 16, making it safer to use.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
