Description

Technical Field

[0001] The utility model relates to the technical field of grooving machines, in particular to an automatic tool changing device for a grooving machine. Background Technique

[0002] A grooving machine (also known as a slot milling machine or a slot planing machine) is a mechanical device used for precise cutting and processing of materials (especially metals and woods). It is mainly used to plane slot holes or grooves on the surface of materials to meet different processing requirements. The spindle: the component for installing the tool, which can rotate at different speeds and is used to drive the tool for cutting. Different tools are selected according to the processing requirements for cutting, grooving or milling. Common tools include straight groove cutters, disc cutters, etc. The main uses of the grooving machine are slot hole processing, used to open slots on the surface of materials. These slot holes can be used for assembly, fitting installation or as part of other processing steps, cutting grooves on the material to enhance the strength of the structure or for assembly, trimming and repairing the workpiece to ensure the accuracy of dimensions and shapes.

[0003] The existing spindle of the grooving machine can only fix a single tool bit. When different types of grooves need to be planed, different types of tool bits need to be replaced. When manually replacing the tool bit, the existing tool bit needs to be disassembled and a new tool bit needs to be installed. This process usually takes a considerable amount of time. Such frequent operations not only increase the processing time but also affect the production efficiency. After replacing the tool bit, tool setting is also required again, especially resetting the Z-axis coordinate. This process usually involves precise measurement and adjustment, further increasing the time cost. The process of replacing the tool bit and resetting the tool will cause the interruption of the production line, thus reducing the continuity and overall efficiency of the production line. During the process of resetting the tool, precision errors may occur, especially during manual adjustment, which may result in the size of the finally processed slot holes not meeting the requirements, thus affecting the quality of the product. When manually replacing the tool bit and setting the tool, operators may make mistakes, resulting in the tool bit not being firmly fixed or the coordinate setting being inaccurate, thus affecting the processing precision.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Reference Figures 1-5, the present utility model discloses an automatic tool changing device for a grooving machine, including a grooving machine moving system 1 and a grooving tool head holder 2 installed on the outer surface of the grooving machine moving system 1. A rotating cavity 3 is provided inside the grooving tool head holder 2. A motor 4 is installed on the inner wall of the rotating cavity 3. A rotating shaft 5 is installed on the outer surface of the output end of the motor 4. A rotating disk 6 is installed on the outer surface of the rotating shaft 5. Air pressure cavities 7 are evenly provided inside the rotating disk 6. A tool head fixing tube 8 is movably installed on the inner wall of the air pressure cavity 7. Tool head fixing components are evenly installed on the outer surface of the tool head fixing tube 8. A tool head stable pushing-out component is installed on the outer surface of the grooving tool head holder 2.

[0021] The tool head fixing components include a threaded groove 9 and a threaded nail 10. The threaded groove 9 is provided inside the tool head fixing tube 8. The threaded nail 10 is movably installed on the inner wall of the threaded groove 9. The tool head stable pushing-out component includes a hydraulic rod 11 and an electromagnet clamping column 13. The hydraulic rod 11 is installed on the outer surface of the grooving tool head holder 2. The electromagnet clamping column 13 is installed on the outer surface of the output end of the hydraulic rod 11. Fixing cavities 15 are provided inside the tool head fixing tube 8. Moving cavities 16 are evenly provided inside the tool head fixing tube 8. The inner wall of the fixing cavity 15 is in movable contact with the outer surface of the electromagnet clamping column 13. A connecting spring 12 is installed on the inner wall of the moving cavity 16. A magnetic clamping block 17 is installed on one end surface of the connecting spring 12. The outer surface of the magnetic clamping block 17 is in movable contact with the inner wall of the moving cavity 16. Claw slots 14 are evenly provided on the outer surface of the electromagnet clamping column 13. The inner wall of the claw slot 14 is in movable contact with the outer surface of the magnetic clamping block 17, which facilitates the automatic replacement of the tool heads inside different tool head fixing tubes 8 inside the rotating disk 6, reduces the labor intensity of the operator, and avoids errors and accidents that may be caused by improper manual operation.

[0022] The rotation of the rotating disk 6 can quickly and accurately complete the tool head replacement, significantly shortening the tool changing time. The efficient tool head replacement process reduces the downtime of the equipment, thereby improving the overall production efficiency, improving the processing quality, and reducing the errors caused by unstable tool heads. The rotating disk 6 can accommodate various different types of tool heads inside and can quickly switch to the required tool head, which provides great flexibility for processing diversified products, makes the operation more intuitive and systematic, and reduces the complexity of the operation.

[0023] Working principle and usage process of the utility model: When it is necessary to replace different types of tool heads to groove the board, the controller controls the motor 4 to work. The motor 4 drives the rotating shaft 5 to perform a rotational motion. The rotating shaft 5 drives the rotating disk 6 to perform a rotational motion, so that the tool head of the type to be used moves below the hydraulic rod 11. When there is no tool head inside the tool head fixing tube 8, one end of the tool head is inserted into the tool head fixing tube 8, and the screw 10 is screwed into the thread groove 9 to fix the tool head in the tool head fixing tube 8, which facilitates the automatic replacement of the tool heads inside different tool head fixing tubes 8 of the rotating disk 6. It reduces the labor intensity of the operator, avoids errors and accidents that may be caused by improper manual operation. The rotational motion of the rotating disk 6 can quickly and accurately complete the tool head replacement, significantly shortening the tool change time. The efficient tool head replacement process reduces the downtime of the equipment, thereby improving the overall production efficiency, improving the processing quality, and reducing the errors caused by unstable tool heads. The rotating disk 6 can accommodate various different types of tool heads and can quickly switch to the required tool head, which provides great flexibility for processing diversified products, makes the operation more intuitive and systematic, and reduces the complexity of the operation.

[0024] When the tool head replacement of the rotating disk 6 is completed, the controller controls the hydraulic rod 11 to work, so that the hydraulic rod 11 drives the electromagnet clamping column 13 to insert into the fixing cavity 15 at the top of the tool head fixing tube 8. When the hydraulic rod 11 drives the electromagnet clamping column 13 to push the tool head fixing tube 8, the tool head fixing tube 8 moves in the air pressure cavity 7. The other air pressure cavities 7 push and suspend the tool head fixing tube 8, and the electromagnet clamping column 13 is powered on, so that the electromagnet clamping column 13 has magnetism. The magnetic block 17 has the opposite magnetism to the corresponding surface of the electromagnet clamping column 13, so that an attractive force is generated between the magnetic block 17 and the electromagnet clamping column 13, causing the magnetic block 17 to drive the connecting spring 12 to move in the moving cavity 16, and the magnetic block 17 is inserted into the card slot 14, so that the electromagnet clamping column 13 is stably connected to the tool head fixing tube 8, making the tool head inside one tool head fixing tube 8 and the tool heads inside other tool head fixing tubes 8 on two horizontal lines, so that the tool head inside one tool head fixing tube 8 stably grooves the board. The stable tool head can ensure the cutting depth and accuracy of the board during the grooving process, reduce deviation, and improve the processing quality. The stable tool head can evenly distribute the pressure, reduce the wear of the tool, thereby extending its service life, reducing the replacement frequency. When the tool head is stable, the tool vibrates less, the noise can be reduced, and at the same time, the processed surface can be ensured to be smooth and flat.
