[0002] Machine tool sliding doors are special protective doors designed specifically for industrial machine tools (especially CNC machine tools), and are typically installed at the front or side opening of the machine tool. They use a sliding opening mechanism (the door panels slide horizontally along a track) and are primarily used to isolate and protect the machining area of ​​the machine tool.

[0003] Stable operation of sliding doors is crucial. Currently, sliding doors on the market use V-shaped wheel guides. However, these guides lack an upper and lower clamping structure (please refer to utility model patents with announcement numbers CN211589428U or CN210948283U). During long-term operation of the machine tool, due to factors such as vibration, the weight of the door body, and sheet metal deformation, the door wheels are prone to loosening, derailment, jamming, or falling off, posing safety hazards.

[0004] Therefore, improving the safety of guide rails is an urgent problem to be solved. Utility Model Content

It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, but is for illustrative purposes only and is not a drawing based on the original dimensions.

[0033] Stable operation of sliding doors is crucial. Currently, sliding doors on the market use V-shaped wheel guides. However, these guides lack a tight upper and lower clamping structure, which can easily lead to loosening, derailment, jamming, or detachment of the door wheels, posing safety hazards.

[0034] To ensure the stability of the sliding door's movement, please refer to... Figure 1 and 2 This utility model provides a machine tool protection device, including a sliding door 100, a sliding component 200 and a protective frame 300.

[0035] The sliding door 100 can be opened or closed to allow operators to load or unload materials. The sliding door 100 is slidably connected to the protective frame 300 via the sliding assembly 200. The sliding door 100 can be a single door or a double door; this embodiment uses a double door as an example, but is not limited to this. The protective frame 300 has an opening, which the sliding door 100 can cover.

[0036] The detailed structure of the sliding component 200 is described below. Please refer to [link / reference]. Figure 3-6 The sliding assembly 200 includes a slidable rolling mechanism 210 and a guide plate 220. The rolling mechanism 210 is connected to the sliding door 100, and the guide plate 220 is fixedly connected to the protective frame 300. The rolling mechanism 210 and the guide plate 220 are slidably engaged. The sliding door 100 is mounted above the rolling mechanism 210. The guide plate 220 is vertically positioned and spaced from the inner side of the protective frame 300 to allow the rolling mechanism 210 to pass through. For example, the mounting base 213 is supported below the sliding door 100, and both ends of the guide plate 220 are fixed to the inner side of the protective frame 300. Alternatively, the guide plate 220 can be U-shaped to facilitate its installation inside the protective frame 300. It is understood that any other installation of the guide plate 220 inside the protective frame 300 is acceptable, as long as there is a gap between the guide plate 220 and the protective frame 300 allowing the rolling mechanism 210 to slide.

[0037] Please refer to Figure 3 and 5 The detailed structure of the rolling mechanism 210 is described below. The rolling mechanism 210 includes a first roller 211, a second roller 212, and a mounting base 213. The first roller 211 and the second roller 212 are along the width direction of the guide plate 220. Figure 3The first roller 211 and the second roller 212 are arranged vertically at intervals on the mounting base 213. Both the first roller 211 and the second roller 212 can roll relative to the mounting base 213, and the first roller 211 and the second roller 212 roll simultaneously, with the first roller 211 and the second roller 212 rotating in opposite directions. The number of the first roller 211 and the second roller 212 can be selected according to the actual situation. Furthermore, the number of mounting bases 213 can also be adjusted according to the actual situation, as long as the sliding door 100 can slide stably and safely.

[0038] Please refer to Figure 4 and 5 The internal structure of the first roller 211 and the second roller 212 is described in detail below. The first roller 211 and / or the second roller 212 include a wheel body 201, a bearing 202, and a connecting shaft 203. The wheel body 201, the bearing 202, and the connecting shaft 203 are sequentially sleeved together. The connecting shaft 203 includes a threaded section 2031 and a mounting section 2032. The connecting shaft 203 is detachably mounted on the mounting base 213 through the threaded section 2031, and the bearing 202 is sleeved on the mounting section 2032. The wheel body 201 is annular, the bearing 202 is also annular, and the connecting shaft 203 extends horizontally. A groove 207 is provided on the outer periphery of the wheel body 201. The groove 207 is annular, and there are stop portions 2071 on both sides of the groove 207. The guide plate 220 is limited to the groove 207 by the stop portions 2071. By providing the groove 207, the guide plate 220 can be axially limited along the connecting shaft 203, preventing the guide plate 220 from detaching from the first roller 211 or the second roller 212 along the axial direction.

[0039] Please refer to Figure 4 The inner circumferential side of the wheel body 201 is provided with an annular groove 2072, and the bearing 202 is installed in the annular groove 2072. The width of the annular groove 2072 is adapted to the width of the bearing 202, so as to facilitate the positioning of the outer ring of the bearing 202 in the annular groove 2072 and facilitate the assembly of the bearing 202 with the inner circumference of the wheel body 210.

[0040] Please refer to Figure 5 and 6 The mounting base 213 is fixedly connected to the sliding door 100. The guide plate 220 passes between the first roller 211 and the second roller 212, and the first roller 211 and the second roller 212 are movably clamped on the guide plate 220. By setting the first roller 211 and the second roller 212, the guide plate 220 can be clamped in the vertical direction, thereby preventing the guide plate 220 from falling off in the vertical direction, and ensuring that the first roller 211 and the guide plate 220 maintain a rolling connection, thus ensuring the stability and safety of the sliding door 100's movement.

[0041] Please refer to Figure 3 and 6 To prevent the bearing 202 from moving axially relative to the connecting shaft 203 and to ensure the stability of the bearing 202 after installation with the connecting shaft 203, a positioning element 2033 protrudes from the outer periphery of the connecting shaft 203. The positioning element 2033 is located between the threaded section 2031 and the mounting section 2032, and one side of the bearing 202 abuts against the positioning element 2033. In this embodiment, the positioning element 2033 is annular and is sleeved on the outer periphery of the connecting shaft 203. The positioning element 2033 abuts against the inner ring of the bearing 202, thereby positioning the bearing 202 in the installation position. In some other embodiments, the positioning element 2033 and the connecting shaft 203 are integrally formed, thereby improving the connection strength between the positioning element 2033 and the connecting shaft 203, reducing the installation process of the connecting shaft 203, and increasing the production volume of the connecting shaft 203. Furthermore, the rolling mechanism 210 also includes a positioning bolt 204, which includes a shaft portion 205 and a limiting flange 206 connected to one end of the shaft portion 205. The shaft portion 205 is coaxially arranged with the connecting shaft 203 and threadedly engaged. The bearing 202 is axially located between the positioning member 2033 and the limiting flange 206. The diameter of the limiting flange 206 is larger than the diameter of the shaft portion 205, thus forming a limiting area between the limiting flange 206 and the positioning member 2033. By adjusting the depth of the screw connection between the shaft portion 205 and the connecting shaft 203, the distance between the limiting flange 206 and the positioning member 2033 can be adjusted, thereby limiting bearings 202 of different widths.

[0042] To prevent the first roller 211 and the second roller 212 from being contaminated by cutting fluid and chips inside the machine tool, the rolling mechanism 210 further includes a cover plate 214, which covers the mounting base 213. Each of the first roller 211, the second roller 212, and a portion of the guide plate 220 is disposed within the cavity enclosed by the cover plate 214 and the mounting base 213. The mounting base 213 is also provided with a clearance opening 2131 for the guide plate 220 to pass through. In this embodiment, the cover plate 214 is plate-shaped, and the mounting base 213 is frame-shaped, thereby forming a receiving space after the cover plate 214 and the mounting base 213 are assembled. In some other embodiments, the cover plate 214 may be frame-shaped, and the mounting base 213 may be plate-shaped. In some other embodiments, both the cover plate 214 and the mounting base 213 are frame-shaped. As long as the cover plate 214 and the mounting base 213 form a receiving space after assembly, they can protect the first roller 211 and the second roller 212.

[0043] To facilitate adjustment of the position of the first roller 211 or the second roller 212 relative to the mounting base 213 along the width direction of the guide plate 220, please refer to... Figure 5 The mounting base 213 is provided with an adjustment hole 2132 for mounting the first roller 211 or the second roller 212. The adjustment hole 2132 extends along the width direction of the guide plate 220. The first roller 211 and / or the second roller 212 are fixed to different positions of the adjustment hole 2132 by fasteners, thereby adjusting the distance between the first roller 211 and the second roller 212. The fasteners can be bolts.

[0044] To facilitate high-precision adjustment of the position of the first roller 211 or the second roller 212 relative to the mounting base 213 along the width direction of the guide plate 220, the machine tool protective device also includes an adjusting bolt. The adjusting bolt is screwed onto the mounting base 213 and abuts against the connecting shaft 203 of the first roller 211 and / or the second roller 212. Each time the adjusting bolt rotates one revolution, the first roller 211 and / or the second roller 212 rises along the width direction of the guide plate 220 by the pitch of the adjusting bolt, thereby enabling high-precision and accurate adjustment of the height of the first roller 211 and / or the second roller 212 relative to the mounting base 213.

[0045] The aforementioned machine tool protective device includes a sliding door 100, a sliding assembly 200, and a protective frame 300. The sliding door 100 is slidably connected to the protective frame 300 via the sliding assembly 200. The sliding assembly 200 includes a relatively slidable rolling mechanism 210 and a guide plate 220. The rolling mechanism 210 is connected to the sliding door 100, and the guide plate 220 is fixedly connected to the protective frame 300. The rolling mechanism 210 includes a first roller 211, a second roller 212, and a mounting base 213. The first roller 211 and the second roller 212 are spaced apart on the mounting base 213 along the width direction of the guide plate 220. The mounting base 213 is fixedly connected to the sliding door 100. The guide plate 220 passes between the first roller 211 and the second roller 212, and the first roller 211 and the second roller 212 are movably clamped on the guide plate 220.

[0046] By setting the first roller 211 and the second roller 212, the guide plate 220 can be clamped in the vertical direction, thereby preventing the guide plate 220 from falling off in the vertical direction. This ensures that the first roller 211 and the guide plate 220 maintain a rolling connection, guaranteeing the stability and safety of the sliding door 100's movement.

[0047] This utility model also provides a machine tool, including a base and the aforementioned machine tool protective device, wherein the protective frame 300 is fixedly connected to the base.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0049] The above-listed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
