Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool protective covers, and particularly relates to a protective cover for a machine tool. Background Art

[0002] A machine tool protective cover is a device used to protect the machine tool and the working environment. It is usually made of flexible materials (such as PVC, polyurethane, nylon, etc.), and can form an adjustable isolation area around the machine tool to prevent substances such as cutting fluid, debris, and dust from splashing out, and at the same time can also prevent operators from accidentally contacting machine parts.

[0003] A transparent plate (hereinafter referred to as an observation plate) is installed on the machine tool protective cover for operators to view the processing state of the workpiece inside the machine tool. However, the side walls at both ends of the observation plate are respectively on the inside and outside of the machine tool. When the temperature difference between the inside and outside of the machine tool is large, fog is likely to appear on it, making it impossible for operators to view the inside of the machine tool. Therefore, this application proposes a protective cover for a machine tool. Summary of the Utility Model

The right-angled side in the right trapezoidal structure is flush with the outer wall of the observation plate, and the hypotenuse in the right trapezoidal structure inclines from top to bottom towards the side close to the observation plate.

[0009] Preferably, there are two lower exhaust ports, and the inner wall of the lower exhaust port is flush with the outer wall of the observation plate.

[0010] Preferably, a water storage box for storing water droplets sliding down from the protective door is detachably installed inside the lower connecting piece. A clamping mechanism is installed inside the water storage box, and the clamping mechanism is used to fix and release the position between the water storage box and the protective door.

[0011] Preferably, the clamping mechanism includes a handle which penetrates the outer wall of the water storage box and is rotatably connected to the box. A circular plate is fixedly installed on the part of the handle inserted into the water storage box. The circular plate is rotatably connected to a connecting plate through a first connecting rod. The other end of the connecting plate is hinged to a pull rod through a second connecting rod. The pull rod is slidably connected to a square pipe fixed in the water storage box.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1-5 , a protective cover for a machine tool, including a machine tool body 1, a protective cover 2, a protective door 3, and an observation plate 4. The observation plate 4 is installed on one or more of the protective doors 3. The observation plate 4 is made of a transparent material, through which the internal situation of the machine tool body 1 can be observed to check the processing progress. The protective door 3 is a part of the protective cover 2 and has the function of opening and closing. The observation plate 4 is to isolate the processing area from the staff, avoiding the contact between the cutting fluid and waste during the processing and the area where the staff is active, and avoiding risks;

[0025] In a further embodiment, the upper and lower ends of the observation plate 4 are respectively installed on the upper connecting piece 5 and the lower connecting piece 7. The upper connecting piece 5 is connected to the exhaust pipe of the power pump 6. The intake pipe of the power pump 6 passes through the protective door 3. An upper exhaust port 501 aligned with the outer wall of the observation plate 4 is provided inside the upper connecting piece 5. The power pump 6 can send the outside air into the inside of the upper connecting piece 5 and discharge it through the upper exhaust port 501. The upper exhaust port 501 is set as a right trapezoidal structure, with the upper part wide and the lower part narrow. There are two upper exhaust ports 501, and the two upper exhaust ports 501 are symmetrically distributed with respect to the center line of the observation plate 4. The right-angled side in the right trapezoidal structure is flush with the outer wall of the observation plate 4, and the hypotenuse in the right trapezoidal structure inclines from top to bottom towards the side close to the observation plate 4. The gas blows towards the outer surface of the observation plate 4 through the upper exhaust port 501, blowing away the moisture on the outer surface of the observation plate 4. Part of the water droplets will slide down along the observation plate 4 under the action of the gas and its own gravity;

[0026] Specifically, a lower exhaust port 701 is provided inside the lower connecting piece 7. There are two lower exhaust ports 701. The inner wall of the lower exhaust port 701 is flush with the outer wall of the observation plate 4, which is used for gas flow and water droplet flow, and the water droplets are poured into the water storage box 8.

[0027] In a further embodiment, a water storage box 8 for storing the water droplets sliding off the protective door 3 is detachably installed in the lower connecting member 7. A clamping mechanism 9 is installed in the water storage box 8, and the clamping mechanism 9 is used to fix and release the position between the water storage box 8 and the protective door 3;

[0028] Specifically, the clamping mechanism 9 includes a handle 901. The handle 901 penetrates the outer wall of the water storage box 8 and the two are rotatably connected. A circular plate 902 is fixedly installed on the part of the handle 901 inserted into the water storage box 8. The circular plate 902 is rotatably connected to a connecting plate through a first connecting rod. The other end of the connecting plate is hinged to a pull rod 903 through a second connecting rod. The pull rod 903 is slidably connected to a square tube 904 fixed in the water storage box 8. A card slot for the cooperation of the pull rod 903 is arranged in the protective door 3. It should be noted that there are two connecting plates, and the two connecting plates are circumferentially arranged around the center of the circular plate 902;

[0029] More specifically, a sector part 905 is installed on one side of the handle 901 close to the outer wall of the water storage box 8. The sector part 905 is attached to the outer wall of the water storage box 8, and a sector block is fixedly installed on the outer wall of the water storage box 8. Two elastic components 906 are installed between the sector block and the sector part 905. The elastic components 906 are inserted into an arc tube, and the arc tube is fixedly installed on the sector block. The sector block and the elastic components 906 can provide the function of keeping the circular plate 902 in the state as Figure 3 、 Figure 4 shown. At this time, the pull rod 903 is inserted into the card slot in the protective door 3, and their positions are fixed. The water storage box 8 is used to receive the water droplets sliding off the outer surface of the observation plate 4. Rotating the handle 901 can pull the pull rod 903 out of the card slot. At this time, the water storage box 8 can be taken out of the protective door 3, which is convenient for separating the two and pouring out the water droplets in the water storage box 8. These water droplets are mixed with the dust adhering to the outer surface of the observation plate 4, and there are many impurities, which are easy to breed bacteria. Therefore, it needs to be cleaned regularly.
