The upper frame 3 and the lower frame 2 are moved upward to open the transparent window 15 of the horizontal machining center, and the transparent window 15 is used to facilitate the operation of the horizontal machining center. The upper frame 3 and the lower frame 2 cooperate with each other to cover the transparent window 15. When the upper frame 3 and the lower frame 2 are moved upward to open the transparent window 15 of the horizontal machining center, the lower frame 2 slides to be located on one side of the upper frame 3, so that the upper frame 3 and the lower frame 2 are stacked, and then the lower frame 2 pushes the upper frame 3 upward to expose the transparent window 15. The stacking of the lower frame 2 and the upper frame 3 reduces the space occupied in the vertical direction.

[0025] As a technical solution further provided by the utility model, a first transparent glass 31 is fixedly mounted on the upper frame 3 , and a second transparent glass 22 is fixedly mounted on the lower frame 2 .

[0026] Specifically, in order to facilitate observation of the horizontal machining center and protect the horizontal machining center at the same time, the first transparent glass 31 fixedly installed on the upper frame 3 and the second transparent glass 22 fixedly installed on the lower frame 2 are used to protect the horizontal machining center, and the cutting conditions in the horizontal machining center can be observed through the transparent glass.

[0027] Furthermore, a workbench 11 is provided on the top of the outer frame 1 , and a limiting frame 12 for allowing the upper frame 3 and the lower frame 2 to move therein is fixedly installed on the top of the workbench 11 .

[0028] Specifically, in order to provide certain support and protection for the upper frame 3 and the lower frame 2 when they move upward, when the lower frame 2 pushes the upper frame 3 upward, the lower frame 2 and the upper frame 3 can slide in the limit frame 12 at the same time, and the limit frame 12 is used to support the lower frame 2 and the upper frame 3. In order to cover the transparent window 15, the inner walls on the opposite sides of the limit frame 12 are symmetrically provided with slides 16, and the upper frame 3 is slidably set in the slides 16. When the slides 16 are used to make the lower frame 2 disengage from the upper frame 3 when pushing, the upper frame 3 is located on one side of the transparent window 15. When the lower frame 2 slides down to the lowest position, the lower frame 2 and the upper frame 3 cooperate with the second transparent glass 22 and the first transparent glass 31 arranged thereon to cover the transparent window 15.

[0029] Furthermore, side plates 21 are symmetrically arranged on the outer walls of the lower frame 2 on opposite sides, and the two side plates 21 are respectively threadedly rotated with the screw rod 4 axially rotatably arranged in the outer frame 1 .

[0030] Specifically, in order to drive the lower frame 2 to move upward and push the upper frame 3 , the screw rods 4 are rotated respectively to make the side plates 21 and the screw rods 4 threadably rotate, and then the lower frame 2 moves upward and pushes the upper frame 3 .

[0031] Furthermore, a driving rod 6 and an auxiliary shaft rod 5 symmetrically arranged for axial rotation are axially rotated in the workbench 11. The first wedge gears 61 fixedly installed at both ends of the driving rod 6 are respectively meshed with the second wedge gears 51 fixedly installed at the first ends of the two auxiliary shaft rods 5. The second wedge gears 51 fixedly installed at the second ends of the auxiliary shaft rods 5 are respectively meshed with the third wedge gears 41 fixedly installed on the outer wall of the screw rod 4.

[0032] Specifically, Figure 4 As shown, a main motor 7 is fixedly installed in the workbench 11, and a first gear 71 is fixedly installed at the output end of the main motor 7, and the first gear 71 is meshed with a second gear 72 fixedly installed on the outer wall of the driving rod 6. The second gear 72 is driven by the first gear 71 through the main motor 7, and then the driving rod 6 rotates, and the first wedge gears 61 at both ends of the driving rod 6 are respectively meshed with the second wedge gears 51 fixedly installed at the first ends of the two auxiliary shafts 5 to rotate the two auxiliary shafts 5, and then the second wedge gears 51 set at the second ends of the two auxiliary shafts 5 are respectively meshed with the third wedge gears 41 fixedly installed on the outer wall of the screw 4, so that the two screws 4 rotate at the same time, and at this time, the side plate 21 and the screw 4 threadedly rotate.

[0033] Furthermore, a first cleaning block 32 is fixedly mounted on the bottom of the upper frame 3 , and the first cleaning block 32 is movably disposed on the second transparent glass 22 .

[0034] Specifically, since a large amount of debris is generated during the cutting process of metal parts in the horizontal machining center, in order to clean the first transparent glass 31 and the second transparent glass 22, a second cleaning block 8 is fixedly installed on the top of the outer frame 1, and the second cleaning block 8 is movably arranged on the first transparent glass 31. When the lower frame 2 moves upward to gradually locate on one side of the upper frame 3, the first cleaning block 32 scrapes the second transparent glass 22 to clean the surface of the second transparent glass 22. Then, when the lower frame 2 pushes the upper frame 3 to move upward, the second cleaning block 8 scrapes the first transparent glass 31 to clean the surface of the first transparent glass 31.

[0035] Furthermore, the lower frame 2 is provided with an inclined surface 23 at one side of the bottom end of the second transparent glass 22 . The lower frame 2 is movably disposed on a support platform 13 disposed in the outer frame 1 , and a cutting inclined surface 14 is disposed on the support platform 13 .

[0036] Specifically, the debris dropped when the second cleaning block 8 scrapes the first transparent glass 31 and the debris dropped when the first cleaning block 32 scrapes the second transparent glass 22 slide along the cutting bevel 14 provided on the support 13 into the horizontal machining center respectively. The bevel portion 23 can facilitate the debris dropped from the second transparent glass 22 to slide along the bevel portion 23 onto the cutting bevel 14.

[0037] Furthermore, the upper frame 3 and the lower frame 2 are stainless steel frames.

[0038] Furthermore, the first cleaning block 32 and the second cleaning block 8 are flexible sponge blocks respectively.

[0039] Working principle: The main motor 7 drives the second gear 72 by the first gear 71, and then the driving rod 6 rotates, and the first wedge gears 61 at both ends of the driving rod 6 are respectively engaged with the second wedge gears 51 fixedly installed at the first ends of the two auxiliary shafts 5 to rotate the two auxiliary shafts 5, and then the second wedge gears 51 set at the second ends of the two auxiliary shafts 5 are respectively engaged with the third wedge gears 41 fixedly installed on the outer wall of the screw 4, so that the two screws 4 rotate at the same time, and at this time the side plate 21 and the screw 4 threadedly rotate. When the lower frame 2 moves up to gradually be located on one side of the upper frame 3, the first cleaning block 32 scrapes the second transparent glass 22 to clean the surface of the second transparent glass 22, and then when the lower frame 2 pushes the upper frame 3 to move up, the second cleaning block 8 scrapes the first transparent glass 31 to clean the surface of the first transparent glass 31. At the same time, the lower frame 2 and the upper frame 3 slide to be located in the limit frame 12, and the limit frame 12 is used to support the lower frame 2 and the upper frame 3, and the transparent window 15 is exposed. The main motor 7 is driven again to move the lower frame 2 downward, and the upper frame 3 is slidably set in the slide 16. When the slide 16 is used to make the lower frame 2 disengage from the upper frame 3, the upper frame 3 is located on one side of the transparent window 15. When the lower frame 2 slides down to the lowest position, the lower frame 2 and the upper frame 3 cooperate with the second transparent glass 22 and the first transparent glass 31 set thereon to cover the transparent window 15.
