Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled machine tools, in particular to a protective door for numerically controlled machine tools. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The computer in the CNC device performs a series of processing on the information recorded in digital and character encoding through the input device, and then sends instructions to the machine tool spindle and feed actuators through the servo system and programmable controller. The machine tool body completes the processing of the workpiece according to these instructions.

[0003] During the operation of the CNC machine tool, the protective door plays a certain role in installation protection. It can prevent the debris generated by the CNC machine tool and the water used for cooling from splashing onto the observer's body, and reduce the moisture of the CNC machine tool observer's clothes and the situation of being scratched by cutting debris.

[0004] However, the traditional protective door has a simple structure and can only provide basic protection and splash prevention functions. In actual application, since the traditional protective doors are mostly cooperated with I-shaped slide rails, such dry friction will cause the gap to become larger, and at the same time, it will cause the friction during the sliding process to increase, resulting in the protective door sliding slowly and the noise increasing during sliding, which in turn results in the protective door having poor protection effect and unstable installation. It has certain installation risks and is not conducive to building a high-quality workshop environment. At the same time, dust and cutting chips often enter the interior of the slide during the cutting process, which makes it difficult for the protective door to slide effectively. Therefore, there is an urgent need for a protective door for CNC machine tools. Utility Model Content

[0009] In addition, a preferred structure is that an extension arm is installed at one end of the mounting seat, an arc-shaped protective cover is fixedly installed at one end of the extension arm, and the arc-shaped protective cover is arranged on the outer side of the moving wheel.

[0010] In addition, a preferred structure is that limiting columns are installed on both sides of the bottom of the mounting seat, elastic clips are installed on the limiting sleeves of the limiting columns, and rotating arms are rotatably installed on both sides away from the limiting columns.

[0011] In addition, a preferred structure is that the elastic clip is V-shaped, and two sides of the elastic clip are respectively clamped and installed in the clamping groove, and the other end of the elastic clip is limited by a limiting column.

[0012] In addition, a preferred structure is that a through hole is opened at one end of the rotating arm, a bearing member is installed in the through hole, and the bearing member is connected to the moving wheel.

[0013] The beneficial effects of the utility model are:

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A protective door for a CNC machine tool comprises a protective door body 1, a plurality of limit blocks 2 are installed in the middle of the bottom end of the protective door body 1, a plurality of sets of rotating arms 6 are arranged through a mounting seat 5 on the side away from the limit blocks 2, a moving wheel 3 is rotatably installed at one end of the rotating arm 6, and a card slot 61 is arranged on the inner wall of the rotating arm 6, an elastic clip 8 is card-connected and installed in the middle of the card slot 61, and the other end of the elastic clip 8 is fixed by a limit column 10.

[0024] Furthermore, a plurality of mounting seats 5 are respectively arranged on both sides of the outer bottom end of the protective door body 1 , and a plurality of sets of rotating arms 6 are rotatably mounted on both ends of the mounting seats 5 .

[0025] Furthermore, an extension arm 7 is installed at one end of the mounting seat 5 , and an arc-shaped protective cover 4 is fixedly installed at one end of the extension arm 7 . The arc-shaped protective cover 4 is arranged on the outer side of the moving wheel 3 .

[0026] Furthermore, limiting columns 10 are installed on both sides of the bottom of the mounting seat 5, and elastic clips 8 are installed in the upper limit sleeve of the limiting columns 10, and rotating arms 6 are rotatably installed on both sides away from the limiting columns 10.

[0027] Furthermore, the elastic clip 8 is V-shaped, and the two sides of the elastic clip 8 are respectively clamped and installed in the clamping groove 61, and the other end of the elastic clip 8 is limited by the limiting column 10. The tightening force generated by the elastic clip 8 tightens the rotating arms 6 on both sides, and enables the moving wheel 3 to slide stably and smoothly in the slide rail.

[0028] Furthermore, a through hole is formed at one end of the rotating arm 6, and a bearing member 9 is installed in the through hole, and the bearing member 9 is connected to the moving wheel 3. The bearing member 9 ensures the stability of the rotation of the moving wheel 3.

[0029] In this embodiment, the protective door body 1 slides smoothly on the designated slide rail through the limit block 2 and the moving wheel 3 set at the bottom. During actual use, the inner wall of the rotating arm 6 is clamped with an elastic clip 8 through the card slot 61. The outward tightening force generated by the elastic clip 8 makes the rotating arm 6 expand outward and makes the moving wheel 3 slide steadily.

[0030] At the same time, an arc-shaped protective cover 4 is provided on one side of the moving wheel 3 through an extension arm 7. The arc-shaped protective cover 4 protects the front end of the moving wheel 3 and can guide debris and other sundries during its movement to prevent the sundries from entering the interior of the moving wheel 3 and affecting its moving stability.

[0031] After long-term use, the elastic clip 8 is taken out through the slot 61 and the limiting column 10 and replaced for maintenance to ensure the sliding stability of the moving wheel 3.

[0032] In the actual use process, the card slot 61 and the limiting column 10 play the role of limiting the installation of the elastic clip 8 to avoid the elastic clip 8 from shifting.

[0033] Among them, during actual use, the reset performance of the elastic clip 8 can improve the absorption and buffering capacity of the protective door body 1 against external impact forces, avoiding direct losses caused by hard collisions. At the same time, the limit block 2 can effectively prevent the protective door body 1 from derailing, and the two sides of the limit block 2 always slide in the slide rails.

[0034] In the utility model, a limit block 3 and a moving wheel assembly are respectively provided at the bottom of the protective door body 1. During actual use, the moving wheel assembly is tightened outward by an elastic clip and slides firmly on the designated guide rail, while being able to effectively alleviate external impact force. After long-term use, the elastic clip 8 in the card slot 61 can be removed and replaced to ensure the stable use of the moving wheel assembly, effectively increase the installation stability of the protective door, and ensure its sliding smoothness.

[0035] At the same time, the setting of the bottom limit block can effectively prevent derailment and ensure the smooth sliding of the protective door. The arc-shaped protective cover set on the outside of the moving wheel can effectively prevent debris from entering the moving wheel and ensure its sliding stability.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
