Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a safety protection device for ultra-precision numerical control machine tools. Background Art

[0002] With the continuous development of science and technology, the workpieces being processed are becoming increasingly precise and accurate. As a type of precision machining equipment, CNC machine tools are generally equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, and represent them in coded digital form, which is then input into the CNC device through an information carrier. After computational processing, the CNC device sends various control signals to control the movement of the machine tool, automatically processing parts according to the shape and size required by the drawing.

[0003] CNC machine tools effectively address the challenges of machining complex, precise, small-batch, and high-variety parts. Compared to manual machining, they offer fewer errors and higher efficiency. However, lathe operations still require human presence to handle emergencies and material loading and unloading. Because machining equipment is sharp and moves at high speeds, operators should maintain a safe distance from the equipment. Furthermore, workpiece debris is generated during machining, and some debris can move at high speeds and pose a risk of injury, necessitating the protection of both personnel and equipment.

[0004] The patent document with publication number CN217991820U discloses an ultra-precision CNC machine tool safety protection device, which moves the long rejection plate through the coordinated use of a fixed plate, a motor, a threaded rod, a threaded block, an L-shaped block, a rotating block, a toothed plate, a gear one, a guide block, a round rod and a gear two. The ultra-precision CNC machine tool safety protection device has the advantage of good safety. During actual use, it can effectively prevent waste chips from splashing at will, thereby effectively ensuring the personal safety of the user. At the same time, the protection device can store the long rejection plate after use, saving space, facilitating user use, and improving the practicality of the protection device.

[0005] However, research has found that the existing ultra-precision CNC machine tool safety protection devices have certain disadvantages when used:

[0006] This safety protection device can prevent waste chips from causing harm to the human body by using a long reject plate, and can be stored away when the workpiece processing is completed, saving space. However, in actual application, since the control components of the long reject plate are stored in the cavity at the top of the machine tool, additional space is required, which easily increases the size of the CNC machine tool and affects the appearance. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, the embodiment of the present application provides an ultra-precision CNC machine tool safety protection device. By arranging the protective plate and the protective back frame on the inner side of the machining groove in the middle of the CNC machine tool, when the rotating cylinder controls the gear to flip, and the protective plate is driven by the arc rack to slide along the inner surface of the arc guard plate under the support of two track arc plates and the arc guard plate, the protective plate can be retracted into the inner side of the protective back frame. The structure is simple, which is conducive to reducing the volume of the CNC machine tool and ensuring the technical effect of beautiful appearance.

[0012] Preferably, the rotating cylinder controls the gear to flip to a fixed angle by rotating the rotating shaft, so that the gear drives the arc-shaped rack meshing with it to drive the protective plate to move, and the protective plate slides from one side to the other along the inner surface of the arc-shaped protective plate and is stored in the inner side of the protective back frame.

[0013] Preferably, a track arc plate is processed on the top inner wall of one side of the arc guard plate, and an arc groove is formed between the outer wall of the track arc plate and the inner wall of the arc guard plate. The arc guard plate is concentrically arranged with the track arc plate, and the two ends of the protective plate are respectively slidably connected to the inside of the two arc grooves.

[0027] Example 1:

[0028] An ultra-precision CNC machine tool safety protection device, such as Figure 1-Figure 5 As shown, it includes a CNC machine tool 1, a protective back frame 3 provided on the back of the middle part of the CNC machine tool 1, and a protective plate 8 provided on the front of the middle part of the CNC machine tool 1. A processing groove 2 is processed on the top of the center of the CNC machine tool 1. The protective back frame 3 includes an L-shaped plate 301. A curved guard plate 302 is integrally formed on one side of the L-shaped plate 301. A visual glass 4 is embedded in the interior of the protective plate 8.

[0029] like Figure 3 As shown, the inner surfaces of both ends of the protective plate 8 are processed with arc-shaped racks 12, the inner side of one arc-shaped rack 12 is meshedly connected with a gear 11, and one side of the gear 11 is assembled and connected with a rotating cylinder 7;

[0030] Among them, by making the protective back frame 3 and the protective plate 8 both accommodated in the interior of the processing tank 2, and assembling the rotating cylinder 7 into the interior of the CNC machine tool 1, when the rotating cylinder 7 is started, it controls the rotation of the rotating shaft, thereby controlling.

[0031] The rotating cylinder 7 rotates the rotating shaft to control the gear 11 to flip a fixed angle, so that the gear 11 drives the arc-shaped rack 12 meshing with it to drive the protective plate 8 to move, so that the protective plate 8 slides from one side to the other side along the inner surface of the arc-shaped guard plate 302 and is finally stored inside the protective back frame 3 (because the protective plate 8 and the protective back frame 3 are both located inside the processing groove 2 at the center of the CNC machine tool 1, the overall volume of the CNC machine tool 1 will not be changed);

[0032] Secondly, in order to provide a movable track for the protective plate 8, the protective plate 8 can be ensured to move stably along the inner surface of the arc-shaped protective plate 302. Figure 2 and Figure 3 As shown, a track arc plate 9 is processed on the top inner wall of one side of the arc-shaped guard plate 302, and an arc-shaped groove 10 is formed between the outer wall of the track arc plate 9 and the inner wall of the arc-shaped guard plate 302. By arranging the arc-shaped guard plate 302 and the track arc plate 9 concentrically, the arc-shaped guard plate 302 and the track arc plate 9 can be used to provide a track for the protective plate 8, so that the two ends of the protective plate 8 are respectively slidably connected to the inside of the two arc-shaped grooves 10, so as to position the protective plate 8 when it moves;

[0033] Secondly, in order to ensure the stable installation of the long plate 6, the support guard plate 8 slides between the track arc plate 9 and the arc guard plate 302, as shown in FIG. Figure 2 and Figure 3 As shown, the bottom of one side of the L-shaped plate 301 is assembled and fixed to the bottom inner wall of the back side of the processing groove 2, and the bottom inner wall of the front side of the processing groove 2 is assembled and connected with a supporting base 5. By assembling and fixing the two ends of the two track arc plates 9 to the back sides of the two ends of the supporting base 5, the supporting base 5 can be used to support one end of the track arc plate 9 to prevent the end of the track arc plate 9 away from the L-shaped plate 301 from being deformed by the gravity of the protective plate 8;

[0034] At the same time, when the protective plate 8 is in a state of blocking the passage between the curved guard plate 302 and the top of the supporting chassis 5, the protective plate 8 is slid toward the bottom inside the curved groove 10 along the inner surface of the curved guard plate 302. After the surface of one side of the protective plate 8 is in contact with the top surface of the supporting chassis 5, the passage between the curved guard plate 302 and the top of the supporting chassis 5 is completely blocked.

[0035] Secondly, in order to limit the movement of the protective plate 8 along the axial direction inside the arc-shaped protective plate 302, so as to avoid affecting the meshing between the gear 11 and the arc-shaped rack 12, as shown in FIG. Figure 3 As shown, limiting arc plates 13 are processed on the inner walls of both ends of the protective plate 8. By locating the two limiting arc plates 13 between the two track arc plates 9, and with one side surface of the two limiting arc plates 13 respectively fitted with one side surface of the two track arc plates 9, the two track arc plates 9 and the two limiting arc plates 13 can be used to cooperate to limit the left and right movement of the arc-shaped protective plate 302.

[0036] The utility model provides an ultra-precision CNC machine tool safety protection device by arranging a protective plate 8 and a protective back frame 3 on the inner side of a processing groove 2 in the middle of a CNC machine tool 1. When the rotating cylinder 7 controls the gear 11 to flip a fixed angle (here, the rotating cylinder 7 can be selected to rotate 30 degrees or 45 degrees, and the overall dimensions of the protective plate 8 and the protective back frame 3 are adjusted according to actual conditions to make the two compatible), the gear 11 drives the arc-shaped rack 12 engaged with it to drive the protective plate 8 to move, so that the protective plate 8 slides from one side to the other side along the inner surface of the arc-shaped guard plate 302 under the support of the two track arc plates 9 and the arc-shaped guard plate 302, and finally the protective plate 8 is retracted into the inner side of the protective back frame 3. The structure is simple and easy to maintain, and will not affect the overall volume of the CNC machine tool 1.

[0037] Example 2:

[0038] On the basis of Example 1, Figure 1-Figure 5 As shown, this embodiment is an additional structure between the track arc plates 9, and a long plate 6 is installed between the inner side surfaces of the middle parts of the two track arc plates 9;

[0039] The middle portion of the long rejection plate 6 is located between the two long rejection plates 6, and the outer surface of the long rejection plate 6 is higher than the outer surface of the track arc plate 9. This facilitates the surface of the long rejection plate 6 to fit the surface of the protective plate 8 when the protective plate 8 slides between the track arc plate 9 and the curved guard plate 302. During the movement of the protective plate 8, the long rejection plate 6 fixed to the track arc plate 9 can be used to remove metal debris on the inner surface of the protective plate 8.

[0040] Secondly, by making the inner surface of the sight glass 4 flush with the inner surface of the protective plate 8, after the surface of the part of the rejection long plate 6 extending from between the two track arc plates 9 is fitted with the inner surface of the protective plate 8 and the sight glass 4, it can be ensured that when the protective plate 8 slides inside the arc groove 10, the surface of the rejection long plate 6 is fitted with the inner surface of the sight glass 4, and the metal debris adhered to the inner surface of the sight glass 4 is removed, ensuring that the operator of the CNC machine tool 1 can observe the processing status of the workpiece through the sight glass 4.

[0041] The present invention provides a safety protection device for ultra-precision CNC machine tools. By assembling a reject long plate 6 between the inner sides of two track arc plates 9, when the reject long plate 6 is made to protrude from between the two track arc plates 9, the outer surface of the reject long plate 6 is made higher than the outer surface of the track arc plate 9 and fits with the surface of the sight glass 4 inside the protective plate 8. Since the inner surface of the protective plate 8 is flush with the inner surface of the sight glass 4, it can be ensured that when the protective plate 8 slides inside the arc groove 10, the surface of the reject long plate 6 fits with the inner surface of the sight glass 4, and metal debris adhered to the inner surface of the sight glass 4 is removed, ensuring that the operator of the CNC machine tool 1 can observe the processing status of the workpiece through the sight glass 4, and there will be no problem of metal debris adhering to the inner surface of the sight glass 4, which affects the light transmittance performance of the sight glass 4.

[0042] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
