Description

Technical Field

[0001] The present invention belongs to the technical field of cutting machines, and in particular relates to a fast manual tool-changing magnetic engraving and cutting all-in-one machine. Background Art

[0002] In modern manufacturing, engraving and cutting are crucial process steps, widely used in a variety of fields, including mold manufacturing, handicraft processing, and mechanical parts processing. With the continuous advancement of industrial technology and the growing market demand for product diversification and refinement, more stringent requirements are being placed on the performance, efficiency, and versatility of processing equipment.

[0003] At present, common cutting machines on the market have many limitations in terms of tool fixing methods and function integration, which seriously restrict the further improvement of processing efficiency and product quality.

[0004] In terms of tool fixing methods: Most existing cutting machines use the traditional method of screw locking to fix the tool, such as in lathes and other equipment. This fixing method has obvious disadvantages in actual operation. On the one hand, the installation and disassembly process of the tool is extremely cumbersome, resulting in slow tool change speed. Operators need to use special tools, such as wrenches, to repeatedly tighten and loosen the screws. The whole process is time-consuming and labor-intensive, greatly reducing production efficiency. Especially in scenarios where tools need to be replaced frequently to adapt to different processing requirements. On the other hand, during long-term use, the screw locking method is prone to wear and loosening between the screws and the threaded holes due to frequent tightening and loosening operations. This will not only affect the stability of the tool fixation, but also cause the tool to shake and deflect during processing, thereby reducing processing accuracy. In severe cases, it may even cause safety accidents such as tool falling off, posing a potential threat to equipment and operators.

[0005] From the perspective of functional integration: existing cutting machines have relatively limited functions and are often only able to focus on a specific function within engraving or cutting. For example, some engraving machines are only capable of finely engraving patterns and text on the surface of materials, but are unable to cope with processing tasks that require deep cutting to remove large amounts of material. Meanwhile, while cutting machines can complete material cutting, they perform poorly in areas such as engraving complex patterns and fine contour processing. This functional limitation means that in actual production, in order to complete a part that requires multiple processing requirements, multiple different types of equipment are often required to perform engraving and cutting processes separately. This not only increases equipment acquisition costs and floor space, but also requires frequent transfer and repositioning of workpieces between different devices, further increasing processing time and the potential for error accumulation, making it difficult to meet the urgent demand for efficient, integrated processing in modern manufacturing.

[0006] Therefore, the inventor is committed to designing a cutting machine to solve the above problems. Summary of the Invention

[0049] Reference Figure 1 and Figure 2 In the present invention, the cutting function of the magnetic engraving and cutting machine is preferably turning. Specifically, the left end of the work table 2 is rotatably connected to a tail top 21 through a T-shaped frame, and the right end of the work table 2 is rotatably connected to a clamping claw 22 through a frame seat. A rotating motor 23 is fixed on the frame seat, and the rotating motor 23 drives the clamping claw 22 to rotate through a belt drive. The tail top 21, the clamping claw 22 and the cutting device composed of the cutting shell 5 and its internal parts together constitute a turning structure.

[0050] Reference Figures 1 to 18 The working principle of the fast manual tool change magnetic engraving and cutting machine of the present invention is as follows:

[0051] Turning process:

[0052] Open the cover 111, use the claw 22 to clamp one end of the workpiece to be turned, and the tail 21 to support the other end of the workpiece to be turned;

[0053] On the one hand, the longitudinal movement motor 241 drives the longitudinal movement screw 242 to rotate, thereby driving the longitudinal movement slider 24 to slide longitudinally along the two longitudinal movement guide rods (i.e., slide back and forth), so that the work table 2 and the tail top 21 and the clamping claw 22 holding the workpiece to be turned on the work table 2 move longitudinally to a suitable position together, thereby adjusting the position of the workpiece to be turned;

[0054] On the other hand, the transverse motor 31 drives the transverse screw 32 to rotate, thereby driving the transverse slider 3 to slide horizontally along the two transverse guide rods (i.e., slide left and right). The vertical slider 4, cutting housing 5, clamping member 7, adjustment sleeve 6, and cutting motor 54 on the transverse slider 3 also move horizontally to adjust the horizontal position of the tool 74.

[0055] On the other hand, the vertical motor 41 drives the vertical screw 42 to rotate, thereby driving the vertical slider 4 to slide vertically along the two vertical guide rods (i.e., slide up and down). The cutting housing 5, the clamping member 7, the adjustment sleeve 6, and the cutting motor 54 on the vertical slider 4 also move vertically therewith, thereby adjusting the vertical position of the tool 74.

[0056] The output shaft of the cutting motor 54 drives the adjustment sleeve 6 to rotate. Since the clamping member 7 is vertically limitedly connected to the adjustment sleeve 6 through the pin 73, the clamping member 7 and the pin 73 rotate together with the adjustment sleeve 6, ultimately controlling the rotation of the cutter 74.

[0057] The rotating motor 23 drives the claw 22 to rotate through a belt drive, and then drives the workpiece to be turned clamped between the tail top 21 and the claw 22 to rotate. The tool 74 can then perform a turning and removing operation on the outer cylindrical surface of the workpiece to be turned to obtain a size and surface quality that meets the design requirements.

[0058] Carving process:

[0059] Place the piece to be engraved on the work surface 2 (you can also use a fixture to position it);

[0060] The longitudinal movement motor 241 drives the longitudinal movement screw 242 to rotate and adjust the longitudinal position of the work table 2;

[0061] Since the laser emitter 10 is magnetically connected to the cutting housing 5, the lateral position of the laser emitter 10 can be adjusted by rotating the lateral movement screw 32 driven by the lateral movement motor 31, and the vertical position of the laser emitter 10 can be adjusted by rotating the vertical movement screw 42 driven by the vertical movement motor 41.

[0062] After the position of the laser emitter 10 is adjusted, the laser head 101 can then engrave the workpiece.

[0063] Tool changing process:

[0064] Remove the laser transmitter 10;

[0065] The operator holds the handle 91 with one hand and manually controls the entire rotary loosening member 9 to rotate downward. The two torsion springs 96 are elastically deformed. At the same time, the two rotating shafts 93 rotate together with the rotary loosening member 9. Each rotating shaft 93 drives the corresponding eccentric shaft 94 to rotate in the corresponding limiting hole 81 of the pressing member 8. The pressing member 8 moves downward and presses down the two ends of the pin 73 (i.e., the part where the pin 73 extends outside the adjustment sleeve 6), so that the entire clamping member 7 moves downward and the spring 63 is compressed. When the rotary loosening member 9 rotates downward to 90 degrees, the clamping claw at the lower end of the clamping member 7 extends outside the adjustment sleeve 6, loosening the tool 74 (such as Figure 18 As shown), the tool 74 can be replaced;

[0066] After the tool 74 is replaced, the handle 91 is released. On the one hand, the two torsion springs 96 restore their elastic deformation, and the entire rotary loosening tool 9 rotates upward and resets under the elastic force of the two torsion springs 96. The two rotating shafts 93 rotate and reset, and the two eccentric shafts 94 drive the tool pressing member 8 to move upward. On the other hand, the spring 63 restores its elastic deformation, and the clamping member 7 moves upward under the elastic force of the spring 63. The pin 73 also moves upward with the clamping member 7 until the clamping claw at the lower end of the clamping member 7 extends into the adjusting sleeve 6 to clamp the new tool 74 (such as Figure 17 As shown), the new tool 74 is replaced;

[0067] Install the laser transmitter.
