[0032] The following will be combined with the drawings in 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.

[0033] like Figure 1 As shown, the utility model provides a detachable and sealed machine tool side door, comprising a machine tool body 1 and a side door 2 installed on the machine tool body 1;

[0034] Machine tool body 1, such as Figure 2-5 As shown, a door frame 11 is provided thereon, the door frame 11 is concave and a water retaining strip 12 is provided on the peripheral side, the water retaining strip 12 is tilted outward along the inner edge of the door frame 11, a water guide groove 13 is provided at the bottom of the door frame 11, the opening is upward, and at the same time, the height of the left wall of the water guide groove 13 is higher than the height of the right wall to prevent the cutting fluid from overflowing, an overflow groove 14 is arranged in parallel at the bottom of the water guide groove 13, and anti-splash holes are staggered at the bottom of the water guide groove 13 and the overflow groove 14 to improve the water leakage effect, have double-layer protection, and improve the waterproof performance;

[0035] Side door 2, such as Figure 6 As shown, it is nested in the door frame 11, and includes a door panel 21, both sides of the door panel 21 are respectively bent inwardly with a first hook-shaped folded edge 22, the top of the door panel 21 is bent inwardly with a second hook-shaped folded edge 23, and the bottom of the door panel 21 is bent outwardly with an L-shaped folded edge 24;

[0036] Specifically,

[0037] The side door 2 is nested in the door frame 11, wherein the bottom of the side door 2 is installed in the water channel 13 and supported by the right wall of the water channel 13, the L-shaped folded edge 24 extends into the machine tool body 1, the outer end surfaces of the first hook-shaped folded edge 22 and the second hook-shaped folded edge 23 of the side door 2 abut against the inner concave surface of the door frame 11, and are installed on the inner side of the water retaining strip 12, with multiple barriers to form a closed water retaining mechanical structure;

[0038] The height of the left wall of the water guide groove 13 is higher than that of the right wall to prevent the cutting fluid from overflowing. When the cutting fluid in the machine tool body 1 splashes toward the side door 2, a part of it is blocked by the water retaining bar 12, and then the rest flows along the water retaining bar 12 into the first hook-shaped folded edge 22, and then flows along the first hook-shaped folded edge 22 to the water guide groove 13, and flows back to the machine tool body 1 through the splash-proof hole.

[0039] Based on the above embodiments, Figure 7 As shown, it also includes an anti-slip screw assembly 3, which is used to lock or loosen the side door 2 and the machine tool body 1, including a screw head 31 and a screw rod 32 fixed at the bottom of the screw head 31, and the surface of the screw rod 32 is threadedly connected with a first nut and a second nut, the first nut is fixed to the inner end of the side door 2, and the second nut is fixed to the inner side of the machine tool body 1, and the first nut is coaxial with the second nut;

[0040] Specifically, two groups of anti-slip screws 3 are provided, which are symmetrically arranged at the upper ends of the side door 2 and the machine tool body 1. The screw head 31 is manually screwed to make the screw 32 screwed into the first nut and the second nut in turn. When the side door 2 is separated from the machine tool body 1, the screw head 31 is manually screwed to separate the screw 32 from the second nut. At the same time, the first nut and the screw 32 are still in a screwed state to avoid falling and adding unnecessary trouble.

[0041] On the basis of the above embodiment, a sealing ring 33 is installed between the screw head 31 and the side door 2 to prevent the cutting fluid from overflowing.

[0042] On the basis of the above embodiment, the first hook-shaped folded edge 22 and the second hook-shaped folded edge 23 are adapted to the inner concave depth of the door frame 11 .

[0043] Based on the above embodiments, Figure 8 As shown, an escape opening is provided at one end of the water retaining strips 12 on both sides that contacts the water guide groove 13 .

[0044] Specifically,

[0045] When installing the side door 2, the operator places the side door 2 in the water channel 13, and uses the right wall of the water channel 13 as a rotation support, and embeds the side door 2 into the door frame 11 clockwise. If no avoidance opening is provided, the side door 2 will inevitably interfere with the water retaining strip 12 during the installation process.

[0046] Based on the above embodiments, Fig. 9 As shown, the outer end surface of the second hook-shaped folded edge 23 protrudes from the outer end surface of the first hook-shaped folded edge 22;

[0047] Specifically,

[0048] Because the surfaces of the machine tool body 1 and the side door 2 need to be painted, when the side door 2 is installed in the door frame 11, the side door 2 uses the right wall of the water guide groove 13 as a rotation support. There is a situation that the lower end of the side door 2 first abuts against the inner concave surface of the door frame 11, resulting in the paint falling off of the lower part of the door frame 11 during the installation of the side door 2, which affects the appearance and the durability of the door frame 11. Therefore, the outer end face of the second hook-shaped folded edge 23 protrudes from the outer end face of the first hook-shaped folded edge 22. During installation, the second hook-shaped folded edge 23 first abuts against the inner concave surface of the door frame 11, which does not affect the overall waterproof structure and at the same time provides a certain protection for the door frame 11.

[0049] On the basis of the above-mentioned embodiment, a window is provided on the door panel 21, and a transparent acrylic plate 4 is installed in the window to assist the operator in observing the machining status of the machine tool.

[0050] In summary:

[0051] The utility model discloses a detachable and sealed machine tool side door. The machine tool body is provided with an inwardly concave sheet metal door frame, a water retaining strip and a water guide groove. The side door is provided with a sheet metal hook-shaped folding edge and an L-shaped folding edge to cooperate with the sheet metal to form a closed water retaining mechanical structure, which can perform multiple isolation on the cutting fluid sprayed toward the side door to prevent the cutting fluid from overflowing from the side door.

[0052] The utility model is provided with an anti-drop screw assembly, which not only ensures the sealing but also prevents falling and adding unnecessary trouble; at the same time, the outer end surface of the second hook-shaped folded edge protrudes from the outer end surface of the first hook-shaped folded edge, which plays a certain protective role on the door frame.
