Description

Technical Field

[0001] The utility model relates to the technical field of engraving machines, and in particular to a main shaft cooling mechanism for engraving machines. Background Art

[0002] The engraving machine is a CNC processing equipment used for engraving, cutting, carving, hollowing and other processing of various materials. In order to avoid the engraving machine generating too high a temperature when processing the material, causing the material to deform and affect the engraving effect, a spindle cooling mechanism is often added to the engraving machine.

[0003] The existing spindle cooling mechanism of the engraving machine is to set a nozzle near the spindle side of the engraving machine, and continuously supply water to the nozzle through a water storage tank to ensure that the nozzle can continuously cool the engraving tool.

[0004] Although this method can achieve the use of a nozzle to cool the engraving tool, it still has the following disadvantages: the engraving tools used by the engraving machine for engraving different materials have different lengths and widths. In order to ensure that the movement of the engraving machine spindle does not affect the nozzle, the nozzle is often fixed on the spindle. When the engraving tool replaced by the engraving machine is longer or shorter than the previous tool, the nozzle position is difficult to change, making it difficult for the nozzle to align with the tip of the engraving tool, resulting in less coolant passing through the position on the tip that needs to be cooled, and low cooling efficiency.

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 2 to Figure 6As shown, this embodiment proposes a spindle cooling mechanism for an engraving machine, and its structure includes a mounting frame 3. The driving motor 5 in this embodiment is fixedly arranged on the mounting frame 3, the spindle 51 is fixedly arranged on the output shaft of the driving motor 5, the engraving tool 52 is detachably arranged on the spindle 51, the mounting nozzle 6 is arranged on the mounting frame 3, the water pipe 21 is fixedly arranged on the mounting nozzle 6, and the water storage tank 2 is connected to the other end of the water pipe 21. The sliding structure is arranged between the mounting nozzle 6 and the mounting frame 3, and is used to adjust the position of the mounting nozzle 6 relative to the mounting frame 3 along the Z-axis direction. The control structure is arranged on the sliding structure, and is used to control the sliding structure. The water storage tank 2 in this embodiment can be arranged next to the engraving machine body 1. The engraving machine body 1 in this embodiment is a prior art, and this embodiment will not be repeated.

[0029] The sliding structure in this embodiment includes a sliding rail 4, which is fixedly connected to the mounting frame 3. The sliding hole 41 is set on the side of the sliding rail 4 away from the mounting frame 3, the sliding groove 42 is set in the sliding rail 4, the sliding member 82 is slidingly set in the sliding groove 42, the sliding direction of the sliding member 82 is parallel to the center line of the engraving tool 52, the first mounting plate 8 is set on the sliding member 82, the connecting member 81 is fixedly set between the first mounting plate 8 and the sliding member 82, the connecting member 81 is slidingly connected to the sliding hole 41, and the first mounting plate 8 is fixedly connected to the installation nozzle 6. The sliding member 82 in this embodiment can be selected as a rectangular parallelepiped structure. Through the cooperation between the sliding member 82 and the sliding rail 4, the installation nozzle 6 is not easily deviated during sliding, ensuring that the installation nozzle 6 can always be aligned with the engraving tool 52. The installation nozzle 6 can be more accurately aligned with the engraving tool 52.

[0030] The installation nozzle 6 in this embodiment includes an extension tube 62 and a nozzle tube 61, and the end of the nozzle tube 61 is aligned with the bottom of the engraving tool 52. There is an obtuse angle between the extension tube 62 and the nozzle tube 61, which is used to ensure that the water flows through the obtuse angle between the nozzle tube 61 and the extension tube 62, so that the water flow can flush the engraving material at the bottom through the oblique angle, which can not only ensure that the heat generated by the friction between the installation nozzle 6 and the engraving material during engraving is reduced, but also the powder generated by the engraving material can be sprayed and washed away, ensuring that the engraving material is clean and tidy after engraving. The extension tube 62 and the nozzle tube 61 are integrally formed. Such a design reduces the production process between the extension tube 62 and the nozzle tube 61, improves production efficiency, and reduces production costs.

[0031] The mounting hole 83 in this embodiment is provided on the first mounting plate 8, the second mounting plate 621 is fixedly provided at the end of the extension tube 62, the extension tube 62 passes through the mounting hole 83, the second mounting plate 621 abuts against the first mounting plate 8, the mounting bolts 622 are provided on the second mounting plate 621, and the second mounting plate 621 is fixedly installed with the first mounting plate 8 by the mounting bolts 622. Such a design enables the installation nozzle 6 to be detachable relative to the first mounting plate 8, and facilitates the disassembly, maintenance and installation of the installation nozzle 6.

[0032] The control structure in this embodiment includes a control bolt 71, which is arranged on the top of the mounting frame 3. The screw rod 7 is rotatably arranged in the sliding rail 4, the control bolt 71 is fixedly connected to the screw rod 7, and the first threaded hole 821 is arranged on the sliding member 82, which is threadedly connected to the screw rod 7. The sliding of the sliding member 82 relative to the sliding rail 4 is achieved by rotating the control bolt 71. Since the rotation stroke of the control bolt 71 is much larger than the movement stroke of the sliding member 82, it is ensured that the sliding position control of the sliding member 82 is more accurate. In this embodiment, the screw rod 7 is used to control the movement of the sliding member 82, so that when the control bolt 71 controls the screw rod 7 to rotate to a suitable position, the screw rod 7 can achieve self-locking with the first threaded hole 821, ensuring that the installation nozzle 6 will not be offset during the movement of the main shaft 51.

[0033] In this embodiment, the second threaded hole 511 is arranged at the bottom of the main shaft 51, and the top of the engraving tool 52 is fixed to the second threaded hole 511 by threaded connection. Such a design ensures that the engraving tool and the main shaft 51 are detachably connected, and facilitates the disassembly, replacement and installation of the engraving tool by the main shaft 51. Moreover, the threaded connection between the engraving tool and the second threaded hole 511 ensures the stable installation of the engraving tool.

[0034] A guide plate 9 is also fixed on the top of the mounting frame 3 in this embodiment. The water pipe 21 is made of rubber material to ensure that the water pipe 21 has a certain degree of scalability, which is convenient for installing the nozzle 6 and prevents the water pipe 21 from breaking during the movement. The water pipe 21 passes through the guide plate 9 and is fixedly connected to the guide plate 9. The design of the guide plate 9 ensures that the water pipe 21 is fixed before entering the nozzle 6, so that the front water pipe 21 will not be randomly stacked due to the movement of the main shaft 51, making the equipment more neat and beautiful.

[0035] The working process of this embodiment is as follows: when the replaced engraving tool 52 is different in length from the original engraving tool 52, first rotate the original engraving tool 52 and remove it, then replace the new engraving tool 52 on the main shaft 51, and then rotate the control bolt 71, and the control bolt 71 drives the screw rod 7 to rotate and adjust the position of the installation nozzle 6, so that the installation nozzle 6 is aligned with the tip of the engraving tool 52.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
