Abstract
Description
Technical Field
[0001] The utility model relates to the field of pneumatic tools, and more specifically, to an anti-splash safety protection device for impact-type pneumatic tools. Background Art
[0002] When impact pneumatic tools such as pneumatic impact drills and pneumatic rivet guns are used on automated production lines, they are usually installed on special machines to achieve more precise, efficient and stable work.
[0003] However, during use, the strong impact between the tool and the workpiece will generate a large amount of debris and particles. These splashes may not only cause harm to the machine operator's body, but also affect the safety of the surrounding environment.
[0004] The current protective structure is generally next to the impact pneumatic tool machine, and a protective plate (transparent) is driven up and down by a lifting device to shield the processing part during processing, thereby protecting the surroundings. However, when the protective plate is moved downward for protection (in the initial state, the protective plate is at a high place and will not block the staff from loading and unloading the machine), it is easy to accidentally hit the staff's arm due to negligence, causing injury to the staff. This runs counter to the installation of protection. At the same time, since different impact pneumatic tool machines have different processing parts, this is prone to incompatibility, resulting in the processing part not being completely shielded, and the safety protection effect is poor.
[0005] Therefore, in order to solve the above technical problems, the present application proposes an anti-splash safety protection device for impact-type pneumatic tools. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model aims to provide a splash-proof safety protection device for impact-type pneumatic tools.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an impact-type pneumatic tool splash-proof safety protection device, comprising a transparent outer plate which is hollow inside and has an opening at the bottom, an inner transparent plate which is slidably connected inside the transparent outer plate, and the inner transparent plate extends from the opening at the bottom thereof, and a rubber pad is provided inside the inner transparent plate, and the safety protection device also comprises:

[0009] A lifting assembly, which is mounted on an impact pneumatic tool processing machine and is used to drive the transparent outer plate and the inner transparent plate to move up and down;
[0010] The height adjustment component is installed between the elastic component and the lifting component, and is used to adjust the height of the transparent outer plate and the inner transparent plate relative to the lifting end of the lifting component to adapt to the processing part of the pneumatic tool on the machine.

[0012] Preferably, sliding rods for sliding sleeves are fixedly connected to both sides of the interior of the shell, and the elastic buffer plate is fixed between the two sliding sleeves to maintain the elastic buffer plate's vertical linear movement.
[0013] Preferably, the lifting assembly includes a vertical plate fixed to the impact pneumatic tool processing machine, the upper and lower sides of the surface of the vertical plate are fixedly connected with bearing seats, and the inside of the bearing seat is fixedly connected with a bearing, and the screw rod is rotatably supported by the bearing, and a lifting block is threadedly connected to the outer wall of the screw rod, and the surface of the lifting block is connected to the shell through a cross bar, and a motor for driving the screw rod to rotate is provided on the surface of the vertical plate near the top, and a guide rail A is fixedly connected to the surface of the vertical plate between the two bearing seats, and one side of the lifting block is slidably connected to the guide rail A through a slider A.

[0016] Preferably, the transparent outer plate and the inner transparent plate are made of tempered glass and are arc-shaped, so that the protective performance is good and the protective range is large.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] 1. When the lifting assembly is operated to drive the transparent outer plate and the inner transparent plate to move downward to shield and protect the processing part, if the staff's arm is not detached in time, it will first hit the rubber pad at the bottom of the inner transparent plate, which is relatively soft to prevent the staff from being scratched.

[0031] When the lifting component 4 is operated to drive the transparent outer plate 1 and the inner transparent plate 2 to move downward to shield and protect the processing part (to prevent splashing), if the staff's arm is not detached in time, it will first hit the rubber pad at the bottom of the inner transparent plate 2. The rubber pad is relatively soft to avoid scratches on the staff. At the same time, the inner transparent plate 2 is forced to move toward the inside of the transparent outer plate 1, and the elastic component in the elastic component 3 is used to buffer the elastic component to prevent the staff from being injured. Among them, the material of the transparent outer plate 1 and the inner transparent plate 2 is preferably tempered glass, which has high strength and good protection performance.

[0032] The elastic component 3 includes a shell 31 with a bottom opening fixed on both sides of the transparent outer plate 1, an elastic buffer plate 34 is movably connected inside the shell 31, a spring 35 is fixedly connected between the top of the elastic buffer plate 34 and the inner surface of the shell 31, a connecting rod 36 is fixedly connected to the bottom of the elastic buffer plate 34, and a connecting plate 37 fixed to the bottom of the inner transparent plate 2 is welded to the end of the connecting rod 36, sliding rods 32 for sliding sleeves 33 are fixedly connected on both sides of the inside of the shell 31, and the elastic buffer plate 34 is fixed between the two sliding sleeves 33. The lifting assembly 4 includes a vertical plate 41 fixed to the impact pneumatic tool processing machine, and the upper and lower sides of the surface of the vertical plate 41 are fixedly connected to bearing seats 42, and the inside of the bearing seat 42 is fixedly connected to a bearing 43, and the screw rod 44 is rotatably supported by the bearing 43. A lifting block 45 is threadedly connected to the outer wall of the screw rod 44, and the surface of the lifting block 45 is connected to the shell 31 through a cross bar 46.
