Description

Technical Field

[0001] This utility model belongs to the field of laser chuck technology, specifically relating to a laser chuck with positioning and guiding function. Background Technology

[0002] The laser chuck is the core clamping device in a laser cutting machine. It uses high-precision pneumatic or CNC technology to stably fix round tubes, square tubes, and irregularly shaped tubes, achieving precise positioning and rotation during the cutting process. It also has anti-deformation design and pressure regulation function to ensure the cutting quality and efficiency of thin-walled tubes and heavy tubes.

[0003] The positioning and guiding function of the laser chuck is achieved by using sensors integrated on the chuck (such as laser displacement sensors) to detect the actual position of the workpiece in real time and send the deviation data to the control system. After calculation, the system drives the actuator (usually to adjust the movement path of the laser cutting head) to accurately compensate for the deviation. This ensures that even if there are errors in the installation of the workpiece or the workpiece itself is deformed, the laser beam can still cut accurately according to the preset program, ultimately achieving high-precision processing.

[0004] Currently, the positioning jaws of laser chucks move synchronously. When slight deviations occur, they cannot be adjusted independently. This phenomenon has become a problem that urgently needs to be solved by people in this field. Utility Model Content

[0014] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-5 The present invention provides a technical solution: a laser chuck with positioning and guiding function, including a main frame 1 and a fixed frame 2. A gear 7 is connected to the back of the main frame 1 by a bearing. The gear 7 meshes with a gear 8. The center of the gear 8 is fixedly connected to the output end of a motor 3. The motor 3 is fixedly connected to the fixed frame 2. The gear 8 is set in the fixed frame 2 and is not connected to the fixed frame 2. The fixed frame 2 is fixedly connected to one side of the main frame 1.

[0016] The cylinder assembly 9 is fixedly connected to the other side of the main frame 1, and four interfaces are provided on the cylinder assembly 9.

[0017] It should be added that the cylinder assembly 9 is existing technology, which uses compressed air as a power source and converts the linear motion generated by air pressure into radial clamping motion through a wedge mechanism, thereby realizing the clamping and releasing of the workpiece.

[0018] The main frame 1 is connected to the chuck body 4 by a bearing at the front. A wedge mechanism is set inside the chuck body 4 (not shown in the figure).

[0019] It should be added that the wedge mechanism is existing technology. The wedge mechanism is a mechanical transmission device composed of a triangular wedge, a slide and a drive component. It is the core transmission component that uses the principle of inclined plane to amplify the axial tension of the cylinder and convert it into the radial clamping force of the jaw.

[0020] The chuck body 4 is fixedly connected to the position sensor 6. There are four position sensors 6, which are distributed in four equal parts on the chuck body 4.

[0021] The chuck body 4 is slidably connected to the jaw assembly 16. The jaw assembly 16 includes a jaw bar 15, a slider 5, and a contact plate 13. There are four jaw assemblies 16, which are equally distributed on the chuck body 4, and each jaw assembly 16 is located between two position sensors 6.

[0022] Four slots are provided on the chuck body 4. The slider 5 is located in the slots of the chuck body 4. One end of the claw rod 15 is fixedly connected to one side of the slider 5, and the other end of the claw rod 15 is fixedly connected to the contact plate 13. Several limiting blocks 14 are provided on the contact plate 13. The limiting blocks 14 pass through the contact plate 13 and are slidably connected to the contact plate 13. The limiting blocks 14 are fixedly connected to the fixing plate 12. The other side of the fixing plate 12 is connected to the threaded rod 11 by a bearing. The threaded rod 11 passes through one end of the claw rod 15 and is threadedly connected to the second stepper motor 10. The second stepper motor 10 is fixedly connected to the claw rod 15.

[0023] Working principle: When the laser chuck needs to work, motor 3 starts, driving gear 8 to rotate, which in turn drives gear 7 to rotate, thus allowing the chuck body 4 to rotate. At the same time, cylinder assembly 9 works, causing the wedge mechanism inside the chuck body 4 to convert the linear motion generated by air pressure into radial clamping motion, thereby allowing jaw assembly 16 to clamp or release the workpiece.

[0024] When a workpiece passes through the central hole of the chuck body 4, the position sensor 6 begins to identify the center point of the workpiece. When a deviation is detected between the center point of the workpiece and the center point of the chuck body 4 (e.g., when the center point of the workpiece is to the upper left of the center point of the chuck body 4), the two stepper motors 10 on the left and top start working respectively, driving the threaded rod 11 to rotate and controlling the height of the limit block 14 until the center point of the workpiece coincides with the center point of the chuck body 4. The jaw lever 15 then moves slightly to make the front end of the contact plate 13 flush with the limit block 14, ensuring the maximum contact area with the workpiece. Based on self-centering, the chuck body 4, through the identification of the position sensor 6, causes the two stepper motors 10 to work separately, finely adjusting the position of the workpiece to keep it on the center line of the chuck body 4, ensuring the accuracy of machining.
