Description

Technical Field

[0001] This utility model relates to the field of industrial quick-clamp chuck technology, specifically to a quick-clamp chuck for a laser marking machine. Background Technology

[0002] As we all know, laser marking machines are widely used in many industries such as electronics, automobiles and hardware due to their advantages such as high precision and non-contact processing, which greatly improves the quality and efficiency of product marking. The chuck is an important component of the laser marking machine, responsible for fixing the workpiece and ensuring the stability and accuracy of the marking process.

[0003] In existing technologies, traditional three-jaw chucks or special clamps usually require manually tightening multiple locking bolts to fix the workpiece, which takes a lot of time to adjust and fix the position of the workpiece. This makes it inconvenient to clamp the workpiece quickly, and it is also inconvenient to quickly disassemble and replace the workpiece after marking, which can easily reduce the marking efficiency of the laser marking machine.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1, please refer to Figures 1 to 4A quick-clamp chuck for a laser marking machine includes a mounting head 1, a rotating track 2, a chuck head 3, a rotating disk 4, a tension spring 5, a positioning pin 6, rotating handles 7, and jaws 8. The rotating track 2 is fixedly connected to one side of the mounting head 1. The chuck head 3 is detachably connected to one side of the rotating track 2. The rotating disk 4 is rotatably positioned between the rotating track 2 and the chuck head 3. The tension spring 5 is detachably connected to the rotating track 2 via a fixed base. The positioning pin 6 is detachably connected to the rotating disk 4, and the tension spring 5 and the positioning pin 6 are detachably connected. Multiple rotating handles 7 are arranged in a circular array on the rotating disk 4. When the laser marking machine motor drives the mounting head 1 and the chuck 3 to rotate to the appropriate position, the rotating handle 7 at the corresponding position can be rotated by force. There are three jaws 8, which are all slidably set on the chuck 3. Each of the three jaws 8 is equipped with multiple clamping posts 15. The multiple clamping posts 15 are of different specifications and can clamp workpieces of different specifications. The mounting head 1, chuck 3, rotating disk 4, rotating handle 7 and jaws 8 are all made of aluminum. The rotating track 2 and the limit rod 12 are both made of stainless steel. The use of stainless steel for the rotating track 2 can reduce the wear resistance between the tension spring 5 and the rotating track 2.

[0037] refer to Figure 3 The fixed base includes a fixed sleeve 9 and a fixed screw 10. The fixed sleeve 9 is connected through the rotating track 2, and the fixed screw 10 is threadedly connected to the fixed sleeve 9. A fixed screw groove matching the fixed screw 10 is opened on the inner side wall of the fixed sleeve 9, and one side of the tension spring 5 is fixedly connected to the fixed screw 10.

[0038] Rotating the fixing screw 10 within the fixing screw groove allows for the installation and removal of the fixing screw 10 on the fixing sleeve 9, facilitating the installation and removal of the tension spring 5 on the rotating track 2. This allows for adjustment of the installation position and angle of the tension spring 5 according to actual working requirements.

[0039] refer to Figure 1 as well as Figure 3 The rotating disk 4 has a positioning port that matches the positioning pin 6, and a hanging ring 11 is detachably provided between the tension spring 5 and the positioning pin 6.

[0040] The positioning pin 6 can be quickly installed and removed on the rotating disk 4 through the positioning port. The hanging ring 11 can quickly install the tension spring 5 on the positioning pin 6. The tension spring 5 can be fixed on one side of the positioning pin 6 or on the other side of the positioning pin 6 in the opposite direction. The pulling direction of the tension spring 5 can be adjusted according to the clamping requirements of the workpiece to be marked by the laser marking machine.

[0041] refer to Figure 2 as well as Figure 4The chuck 3 has three limiting ports for the sliding of the claw 8, and the claw 8 is fixedly connected to the side of the rotating disk 4 with a limiting rod 12. The rotating disk 4 has three limiting tracks for the movement of the limiting rod 12.

[0042] When the rotating disk 4 rotates, the three limit rods 12 will move simultaneously in the three limit tracks, so as to drive the three jaw clamps 8 to move simultaneously. When the three jaw clamps 8 move, the three limit ports will limit the movement trajectory of the three jaw clamps 8 respectively, so that the three jaw clamps 8 can stably clamp the workpiece.

[0043] refer to Figure 1 Multiple connecting screws 13 are threaded between the chuck 3 and the mounting head 1, and the mounting head 1 has a mounting port that matches the motor shaft. Multiple set screws 14 are detachably provided on the mounting head 1.

[0044] By tightening multiple connecting screws 13 between the clamp 3 and the mounting head 1, the clamp 3 can be installed and removed on the mounting head 1 for easy replacement. Simultaneously, after the motor shaft of the laser marking machine is installed in the mounting port, multiple set screws 14 can be used to omnidirectionally hold and position the motor shaft, improving the stability of the motor shaft on the mounting head 1. This enhances the stability of the connection between the motor and the mounting head 1, allowing the motor shaft, mounting head 1, and clamp 3 to rotate concentrically. Depending on actual requirements, the mounting port can accommodate motor shafts of different diameters, such as 5mm, 6mm, 8mm, 10mm, or 12mm.

[0045] It should also be noted that the quick-clamp chuck of this laser marking machine can be used to produce different colors according to customer requirements, such as various solid colors and various mixed colors.

[0046] In summary, the laser marking machine uses a quick-clamp chuck to first place the workpiece to be marked between the three jaws 8. Based on the workpiece's specifications and clamping requirements, the tension spring 5 is pulled to the appropriate direction, and the hanging ring 11 is attached to the positioning pin 6. When the tension spring 5 is in the positive direction, the three jaws 8 gradually close to provide external support and clamping for the workpiece (at this time, the workpiece is located within the clamping range formed by the three jaws 8). When the tension spring 5 is in the negative direction, the three jaws 8 gradually open to provide internal support and clamping for the workpiece (at this time, the three jaws 8 are located in the inner circle of the workpiece). Then, force is applied to the rotating handle 7 at the appropriate position to rotate the rotating disk 4. When the rotating disk 4 rotates, the three jaws 8 move simultaneously, allowing for rapid clamping of the workpiece. The tension spring 5 then applies tension to the positioning pin 6 and the rotating disk 4, tightening the three jaws 8, thus improving the stability of the three jaws 8 in clamping the workpiece and simultaneously enhancing the stability of the laser marking machine during workpiece marking.

[0047] Example 2, please refer to Figure 5as well as Figure 6 To improve the applicability of the quick-clamp chuck for the laser marking machine, different types of chuck steps can be installed according to the specifications of the workpiece to be marked, such as one-step or two-step chuck, which can improve the positioning accuracy and clamping effect for workpieces of different specifications.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
