[0002] A vertical machining center is a machine tool used for high-precision metal processing and part manufacturing. It has the characteristics of a fixed workbench and the tool moving in the vertical direction. Vertical machining centers are widely used in fields such as aerospace, automotive manufacturing, mold manufacturing, and machining. It can perform various machining operations such as milling, drilling, tapping, and cutting, and has the characteristics of high precision, high efficiency, and flexibility.

[0003] The existing patent with the publication number CN220761841U discloses a protection mechanism for a vertical machining center. Although it has the function that by driving a lead screw to rotate through a driving motor, a slider can drive a cleaning block to slide, and at this time the cleaning block can drive a rubber wiper to clean the surface of the visible glass. By starting a small water pump, multiple nozzles can spray water on the surface of the visible glass, which can improve the cleaning effect of the rubber wiper.

[0004] Based on the above, the inventor found the following problems: However, this protection mechanism has been in a static state all the time, resulting in inconvenience when placing an object to be processed in the vertical machining center, and it is also inconvenient to take out the processed workpiece. At the same time, when using the rubber wiper for cleaning, there are objects moving on the surface of the protection mechanism, which affects the operation of workpiece processing.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a protection mechanism for a vertical machining center is provided, in order to achieve a more practical value purpose. Summary of the Utility Model

[0026] Embodiment:

[0027] As shown in the appended Figure 1 to the appended Figure 4 shown:

[0028] The present utility model provides a protective mechanism for a vertical machining center, including a base 1. A machining center body 2 is fixed on the top of the base 1. A processor 3 is fixed on the top of the middle part of the machining center body 2. A first chute 4 and a second chute 5 are opened at the bottom of one side of the opening of the machining center body 2. A first driven rack 10 is slidably connected inside the first chute 4, and a second driven rack 11 is slidably connected inside the second chute 5. A first support rod 6 is fixed in the middle of the side of the base 1 close to the opening of the machining center body 2. A servo motor 7 is fixed on the top of the first support rod 6. A rotating shaft 8 is fixed at the power output end of the servo motor 7. A driving gear 9 is fixed at one end of the rotating shaft 8. A first connecting rod 101 is fixed on one side of the first driven rack 10, and a second connecting rod 111 is fixed on one side of the second driven rack 11. Transparent toughened glasses 12 are fixed on the tops of both the first connecting rod 101 and the second connecting rod 111.

[0029] Among them, the first chute 4 is located above the middle left side of the bottom of the machining center body 2, and the second chute 5 is located below the middle right side of the bottom of the machining center body 2. The sum of the length values of the first chute 4 and the second chute 5 is greater than the width value of the opening of the machining center body 2, so that the first driven rack 10 can move fully in the first chute 4, and the second driven rack 11 can move fully in the second chute 4.

[0030] Among them, the first driven rack 10 and the second driven rack 11 are arranged in parallel. Both the first driven rack 10 and the second driven rack 11 are meshed with the rotating shaft 8. By driving the rotating shaft 8 to rotate through the servo motor 7, the driving gear 9 is driven to rotate, thereby driving the first driven rack 10 and the second driven rack 11 to move in the opposite directions, and further driving the two transparent toughened glasses 12 to move closer to the middle simultaneously, or to separate from both ends simultaneously.

[0031] Among them, the height value of the second connecting rod 111 is greater than the height value of the first connecting rod 101. A groove 112 is opened at one end of the second connecting rod 111 close to the servo motor 7, so that the bottoms of the two transparent toughened glasses 12 can be at the same height. By providing the groove 112, when the second connecting rod 111 moves to the servo motor 7, the second connecting rod 111 will not touch the rotating shaft 8 and will not affect the rotation of the servo motor 7.

[0032] Among them, at the top of both ends of the open side of the machining center body 2, second support rods 13 are fixedly installed. At one end of each of the two second support rods 13, a cleaning scraping rod 14 is fixedly installed, and the two transparent tempered glass panes 12 are respectively cleaned by the correspondingly arranged two cleaning scraping rods 14.

[0033] Among them, one side of the cleaning scraping rod 14 is attached to one side of the transparent tempered glass 12, and the height value of the transparent tempered glass 12 is adapted to the height value of the cleaning scraping rod 14. Water guide pipes 15 are fixedly installed on the opposite sides of the two cleaning scraping rods 14. By guiding water through the water guide pipes 15, the two water guide pipes 15 spray water simultaneously.

[0034] Among them, the two water guide pipes 15 are hermetically connected in a communicating manner, and drain holes 151 are provided near the second support rods 13 on the water guide pipes 15. A plurality of drain holes 151 are provided, and the plurality of drain holes 151 are arranged vertically and equidistantly. The water sprayed by the two water guide pipes 15 is sprayed on the inner surface of the transparent tempered glass 12. As the transparent tempered glass 12 moves, the water droplets are driven to move towards the cleaning scraping rod 14, and the cleaning scraping rod 14 cleans the transparent tempered glass 12 when it moves.

[0035] The specific usage method and function of this embodiment:

[0036] In this utility model, when a workpiece needs to be placed in the middle of the machining center body 2, first, control the servo motor 7 to rotate, drive the rotating shaft 8 to rotate, and then drive the driving gear 9 to rotate, thereby driving the first driven rack 10 and the second driven rack 11 to move in opposite directions. Then, drive the two transparent tempered glass panes 12 to separate from both ends simultaneously. After placing the workpiece in the machining center body 2, control the servo motor 7 to rotate in the reverse direction, so that the two transparent tempered glass panes 12 move towards the middle simultaneously, and the two transparent tempered glass panes 12 are closed for protection during processing. After processing is completed, control the servo motor 7 to rotate, drive the two transparent tempered glass panes 12 to separate from both ends simultaneously, and at the same time guide water through the water guide pipes 15. The two water guide pipes 15 spray water simultaneously. The water sprayed by the two water guide pipes 15 is sprayed on the inner surface of the transparent tempered glass 12. As the transparent tempered glass 12 moves, the water droplets are driven to move towards the cleaning scraping rod 14, and the cleaning scraping rod 14 cleans the transparent tempered glass 12 when it moves. Then, remove the processed workpiece.
