Description

Technical Field

[0001] This utility model relates to the field of machine tool protective cover technology, and in particular to a machine tool safety protective cover. Background Technology

[0002] Machine tool protective covers are auxiliary devices installed on machine tools. They generally consist of a track and a movable protective cover or glass protective door. The protective cover can shield the splashes generated by the machine tool during operation and prevent them from spreading outward, thereby protecting the workers. However, the existing safety protective covers installed on machine tools generally have the problem of taking up a lot of space in actual use.

[0003] For example, Chinese utility model patent CN222643950U discloses a safety guard for CNC machine tools, which relates to the field of CNC machine tool technology and includes the main body of the CNC machine tool. Although this solution allows the slider and the frame fixed at the top of the slider to slide out directly through the opening, making it convenient to clean the frame, the frame of the guard adopts an arch bridge design, spanning both sides of the machine tool. Even if the guard frame can be moved to one side along the sliding grooves on both sides, it still occupies a large space above the machine tool. If the machine tool needs to process large-sized workpieces, it may be impossible to load the material due to the large space occupied by the frame above the machine tool. Based on this, a machine tool safety guard that can solve the above problems is proposed. Utility Model Content

[0004] To address the technical problem of insufficient loading space caused by the large space occupied by machine tool protective covers, this utility model provides a machine tool safety protective cover.

[0005] This utility model is achieved using the following technical solution: a machine tool safety guard, comprising two reinforcing plates, with multiple outer connecting rods and multiple inner connecting rods fixedly connected between the two reinforcing plates respectively. The multiple outer connecting rods and multiple inner connecting rods are arranged in a circumferential array, and the circumference of the multiple inner connecting rods is located inside the circumference of the multiple outer connecting rods. Rollers are rotatably connected to both ends of each outer connecting rod and inner connecting rod. A trapezoidal groove is formed on the side of each roller. Track plates are rotatably connected to the upper and lower grooves of the rollers on both sides. A curved metal plate is fixedly connected between the track plates on both sides. A curved glass window is installed on the curved metal plate. A mounting and fixing mechanism is provided on one side of the reinforcing plate, and a push handle mechanism is provided on the lower side of the curved metal plate.

[0006] As a further improvement to the above solution, the mounting and fixing mechanism includes a second slide rod that is slidably connected to the two reinforcing plates. A connecting plate is fixedly connected to the lower side of the two reinforcing plates. A first slide rod is slidably connected to the lower side of the connecting plate. A machine tool docking plate is fixedly connected to both ends of the first slide rod and the second slide rod. The machine tool docking plate is installed on one side of the machine tool.

[0007] As a further improvement to the above solution, the push handle mechanism includes a fixed plate fixedly connected to the lower side of the curved metal plate, and multiple push handles are installed on the outer side of the fixed plate.

[0008] As a further improvement to the above solution, an arc-shaped box is simultaneously fitted on the outer side of multiple outer connecting rods and multiple inner connecting rods, and the two sides of the arc-shaped box are respectively fixedly connected to one side of two reinforcing plates.

[0009] As a further improvement to the above solution, a baffle is fixedly connected to the side of the arc-shaped box near the curved glass window, and a limiting groove is provided on the baffle.

[0010] As a further improvement to the above solution, a stop block is fixedly connected to the side of the curved metal plate away from the curved glass window, and the stop block is configured to cooperate with the baffle.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The machine tool safety guard of this utility model can be stored in the arc-shaped box by rollers when not in use, thereby saving space on one side of the machine tool worktable and facilitating material loading during machine tool processing;

[0013] 2. This utility model adds track plates to both sides of the curved metal plate, and installs rollers with trapezoidal grooves on both the outer and inner connecting rods. This results in less resistance, lower noise, and smoother movement when the curved glass window is extended or retracted. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example:

[0024] Please combine Figure 3 This embodiment of a machine tool safety guard includes two reinforcing plates 4. Multiple outer connecting rods 15 and multiple inner connecting rods 16 are fixedly connected between the two reinforcing plates 4. The multiple outer connecting rods 15 and multiple inner connecting rods 16 are arranged in a circumferential array, and the circumference of the multiple inner connecting rods 16 is located inside the circumference of the multiple outer connecting rods 15. Rollers 14 are rotatably connected to both ends of each outer connecting rod 15 and inner connecting rod 16. Each roller 14 has a trapezoidal groove on its side. Track plates 11 are rotatably connected to the upper and lower grooves of the two rollers 14. Curved metal plates 9 are fixedly connected between the two track plates 11. Curved glass windows 7 are installed on the curved metal plates 9. A mounting and fixing mechanism is provided on one side of the reinforcing plate 4, and a push handle mechanism is provided on the lower side of the curved metal plate 9.

[0025] It should be noted that the outer side of the reinforcing plate 4 is provided with reinforcing ribs, which are intended to improve the rigidity of the reinforcing plate 4 and provide support for the stability of the curved glass window 7. The groove on the roller 14 adopts a trapezoidal design, which can effectively prevent the reinforcing plate 4 from derailing when it moves at high speed.

[0026] Please combine Figure 2 As shown, the mounting and fixing mechanism includes a second slide rod 3 that is slidably connected to the two reinforcing plates 4. A connecting plate 12 is fixedly connected to the lower side of the two reinforcing plates 4. A first slide rod 2 is slidably connected to the lower side of the connecting plate 12. A machine tool docking plate 1 is fixedly connected to both ends of the first slide rod 2 and the second slide rod 3. The machine tool docking plate 1 is installed on one side of the machine tool.

[0027] The above technical solution facilitates the transfer and repositioning of the curved glass window 7 along the longitudinal direction of the machine tool, providing flexibility in the use of the protective cover.

[0028] Please combine Figure 1 As shown, the push handle mechanism includes a fixed plate 8 that is fixedly connected to the lower side of the curved metal plate 9. Two push handles 10 are installed on the outer side of the fixed plate 8. The push handles 10 facilitate the user to pull out the curved glass window 7 and also facilitate longitudinal movement.

[0029] Please combine Figure 2 As shown, multiple outer connecting rods 15 and multiple inner connecting rods 16 are simultaneously fitted with arc-shaped housings 5. The arc-shaped housings 5 ​​can prevent external dust from entering the roller 14 area. The two sides of the arc-shaped housings 5 ​​are respectively fixedly connected to one side of two reinforcing plates 4.

[0030] Please combine Figure 3 As shown, a baffle 6 is fixedly connected to the side of the arc-shaped box 5 near the curved glass window 7. A limit groove 17 is provided on the baffle 6. A stop block 13 is fixedly connected to the side of the curved metal plate 9 away from the curved glass window 7. The stop block 13 is set in cooperation with the baffle 6.

[0031] It should be noted that the limiting groove 17 after the baffle 6 is opened allows the curved metal plate 9 to rotate in an arc shape inside the limiting groove 17. When it rotates to the end, the baffle 6 can interfere with and block the stop block 13 installed on one side of the curved metal plate 9, thereby preventing it from falling off.

[0032] The implementation principle of a machine tool safety guard in this application embodiment is as follows: When the machine tool is working and grinding, it is necessary to block the splashes through the guard. First, the arc-shaped box 5 on one side is moved upward to the processing area on one side along the first slide rod 2 and the second slide rod 3. Then, the curved metal plate 9 inside the arc-shaped box 5 is pulled down by the pusher 10 on the baffle 6 located above. The curved metal plate 9 will rotate within the circumferential trajectory formed by the inner and outer rollers 14. The rollers 14 use their own grooves to limit the track plates 11 installed on both sides of the curved metal plate 9 to prevent the track plates 11 from deviating.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
