Abstract
Description
Technical Field
[0001] This application relates to the field of metal cutting technology, and in particular to a metal cutting auxiliary positioning component. Background Technology
[0002] Laser cutting is a common metal cutting device. It utilizes a high-energy-density laser beam focused on the surface of a material, causing the material to rapidly melt and vaporize. Simultaneously, high-pressure gas coaxial with the laser beam blows away the molten or vaporized material, thus achieving cutting. Its principle is based on the high-energy characteristics of lasers and the absorption and melting properties of materials to laser light. The laser beam is generated by a laser generator and focused onto the surface of materials such as sheet metal through an optical system. After absorbing laser energy, the material's temperature rises rapidly, reaching its melting point and beginning to melt. Upon further absorption of energy, it reaches its boiling point and vaporizes.
[0003] Currently, when using laser cutting equipment to cut metal, positioning fixtures are typically used to clamp and fix the metal in order to improve the cutting accuracy. However, in actual processing, it has been found that some parts of the metal need to be cut, so the position of the metal needs to be changed. However, repeated disassembly and reassembly of the metal will affect the processing efficiency. Therefore, to solve the above problems, this application provides a metal cutting auxiliary positioning component. Utility Model Content
[0004] To address the issue of needing to repeatedly disassemble and reassemble the metal when adjusting its position, this application provides a metal cutting auxiliary positioning component.
[0005] This application provides a metal cutting auxiliary positioning component, including a base with through holes at all four corners, a positioning adjustment component on the top of the base, a handwheel rotatably connected to one side of the base, a horizontal plate, a slot at the center of the top of the base, symmetrical sliding grooves on the top of the horizontal plate, sliders symmetrically slidably connected inside the sliding grooves on both sides, bolts installed on the sliders on both sides, clamping plates symmetrically fixedly connected to the sliders on both sides, a cavity on the inner side of the base, a worm gear rotatably connected inside the cavity, a rotating shaft rotatably connected inside the cavity, and a gear fixedly connected to the rotating shaft.
[0006] Preferably, the clamping plates on both sides are vertically arranged on the top of the horizontal plate, and the horizontal plate is arranged inside the slot.
[0007] Preferably, the worm gear is arranged laterally inside the cavity, and the handwheel is fixedly connected to the end of the worm gear.
[0008] Preferably, the worm is located on one side of the rotating shaft, and the worm is engaged with the gear.
[0009] Preferably, the slot is in communication with the cavity, and the horizontal plate is fixedly connected to the top of the rotating shaft.
[0010] In summary, this application includes the following beneficial technical effects:
[0011] By designing a positioning and adjustment component, when cutting metal using a laser cutting device, the metal is placed on top of the horizontal plate. Multiple sliders inside the side grooves are then moved, causing the clamping plates on both sides to move with the sliders, thus clamping the metal. The sliders and clamping plates are then locked with bolts. For subsequent adjustments, rotating the handwheel drives the worm gear, which in turn drives the rotating shaft and the horizontal plate, adjusting the position of the metal. Compared to existing technologies, this design allows for changing the position of the clamped metal without disassembly, facilitating processing of other parts of the metal and effectively improving processing efficiency.

[0017] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.
[0018] Example:
[0019] A metal cutting auxiliary positioning component is used for clamping and positioning metal during laser cutting, as shown in the reference. Figure 1The device includes a base 1, with through holes 2 at each of the four corners. The base 1 can be easily installed on a laser cutting device through the through holes 2. The top of the base 1 is equipped with a positioning adjustment component 3. The positioning adjustment component 3 can be used to adjust the position of the clamped metal during subsequent cutting, which is convenient for cutting other areas of the metal. A handwheel 4 is rotatably connected to one side of the base 1, which can be used to adjust the subsequent drive device.
[0020] In use, the base 1 is installed on the laser cutting equipment through the through hole 2. Then, the positioning adjustment component 3 is used to make it easy to adjust the position of the clamped metal during subsequent cutting, eliminating the need to disassemble the metal and facilitating the cutting and processing of other areas of the metal.
[0021] Reference Figure 2 - Figure 4 The positioning and adjusting assembly 3 includes a horizontal plate 5, which is circular. A slot 6 is formed at the center of the top of the base 1, and the horizontal plate 5 is positioned inside the slot 6, allowing it to rotate within it. Symmetrical sliding grooves 7 are formed on the top of the horizontal plate 5, facilitating the installation and subsequent movement of sliders 8. Sliders 8 are symmetrically slidably connected inside both sides of the sliding grooves 7, allowing them to move within the grooves. Bolts 9 are installed on both sides of the sliders 8, allowing them to lock after movement. Clamping plates 10 are symmetrically fixed to both sides of the sliders 8, facilitating the clamping and fixing of metal parts. Both clamping plates 10 are vertically positioned on the top of the horizontal plate 5. A cavity 11 is formed inside the base 1, allowing for... For the installation and operation of subsequent components, a worm gear 12 is rotatably connected inside the cavity 11. The worm gear 12 is horizontally positioned inside the cavity 11, and a handwheel 4 is fixedly connected to the end of the worm gear 12, so that rotating the handwheel 4 drives the worm gear 12 to rotate. A rotating shaft 13 is rotatably connected inside the cavity 11, and a gear 14 is fixedly connected to the rotating shaft 13. The slot 6 is kept in communication with the cavity 11, and a horizontal plate 5 is fixedly connected to the top of the rotating shaft 13, so that the horizontal plate 5 can rotate with the rotating shaft 13. The worm gear 12 is located on one side of the rotating shaft 13, and the worm gear 12 is engaged with the gear 14, so that the rotation of the worm gear 12 can drive the rotation of the gear 14. The worm gear 12 and the gear 14 can achieve self-locking. The self-locking condition of the worm gear 12 depends on the helix angle of the thread, the coefficient of friction, and the load. The thread self-locking condition can be calculated by the following formula: Self-locking condition = Coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above content is all existing technology. In practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated here.
[0022] During processing, the metal is placed on top of the horizontal plate 5, and then the multiple sliders 8 inside the sliding grooves 7 on both sides are moved, so that the clamping plates 10 on both sides move with the sliders 8, thereby clamping the metal through the clamping plates 10 on both sides. Then, the sliders 8 and the clamping plates 10 are locked by bolts 9. During subsequent adjustment, the handwheel 4 is turned, which drives the worm gear 12 to rotate, thereby driving the gear 14 to rotate, which in turn drives the rotating shaft 13 and the horizontal plate 5 to rotate, thereby adjusting the position of the metal.
[0023] This application embodiment discloses a metal cutting auxiliary positioning component. Its working principle is as follows: In use, the base 1 is installed on the laser cutting equipment through the through hole 2, and the metal is placed on top of the horizontal plate 5. At this time, multiple sliders 8 inside the sliding grooves 7 on both sides are moved, causing the clamping plates 10 on both sides to move with the sliders 8, thereby clamping the metal through the clamping plates 10. Then, the sliders 8 and clamping plates 10 are locked by bolts 9. For subsequent adjustment, the handwheel 4 is rotated, causing the worm gear 12 to rotate, which in turn drives the gear 14 to rotate, causing the gear 14 to drive the rotating shaft 13 and the horizontal plate 5 to rotate, thus adjusting the position of the metal.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
