Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and in particular to a protective structure for machining centers. Background Technology

[0002] A machining center is a highly automated CNC machine tool primarily used for machining workpieces with complex shapes. It features high efficiency, high precision, and multifunctionality. For safety, machining centers are typically equipped with protective structures, including sliding doors, for easy loading, unloading, and maintenance.

[0003] Machining centers generate debris and dust during processing. Due to design flaws in some machining center sliding doors, these debris can easily accumulate in the slide rails, making cleaning difficult. Prolonged use of the machining center can affect the normal operation of the sliding doors, causing them to jam and become sluggish.

[0004] For example, Chinese patent application number CN202222600711.5 describes a novel noise reduction device for machining centers, comprising a vertical machining center housing. The inner bottom wall of the housing has a track groove, and a first sliding door and a second sliding door are slidably connected to the inner wall of the track groove. The housing, the first sliding door, and the second sliding door are all constructed of sound-insulating panels and protective steel plates fixedly installed on both sides of the sound-insulating panels. A guide block made of magnet is provided on the left side of the first sliding door, and a guide groove matching the guide block is provided on the right side of the second sliding door. This design makes it easy for foreign objects to accumulate between the guide rail and the guide groove, making cleaning difficult. After prolonged use, the machining center may experience problems such as jamming and uneven operation of the sliding doors.

[0005] For example, Chinese patent application CN201820444087.5 discloses a sliding door for a machining center, specifically stating that "by setting sealing rubber on both sides of the upper and lower tracks, particles such as iron filings are not easily allowed to enter the sliding door tracks when the door is open or closed; by installing rubber blocks on both sides of the bottom of the sliding door panel, not only can small particles on the tracks be prevented from falling into the ball bearing grooves, but the rubber blocks can also clean debris from the tracks when the sliding door moves." However, foreign objects can still enter the tracks, and cleaning is inconvenient. After prolonged use, the machining center will affect the normal operation of the sliding door, leading to problems such as jamming and uneven movement. Utility Model Content

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] Please refer to Figures 1 to 5As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a protective structure for a machining center.

[0032] The cutting debris falls from top to bottom, so it won't fall onto the first guide rail 22 or the first slider 115. Meanwhile, since the second guide rail 16 is suspended, the debris won't accumulate there; instead, it will fall directly from the side of the second guide rail 16 into the pedal 114. The track doesn't need cleaning, so the sliding door 20 won't experience jamming even after prolonged use.

[0033] This application provides a protective structure for a machining center, including a protective body 10. The protective body 10 has a sliding door 20 with a window 21. A first guide rail 22 is located at the top of the sliding door 20, and a pulley 23 is located at the bottom. A first slider 115 is located at the top of the protective body 10. A second guide rail 16 is suspended inside the protective body 10, and a foot pedal 114 is located below the second guide rail 16. A clearance groove 17 is located at the bottom of the protective body 10, with the end of the second guide rail 16 extending into the clearance groove 17. The first guide rail 22 slides along the first slider 115, and the pulley 23 moves along the second guide rail 16. A housing 110 is located at the first edge of the protective body 10, and an air conditioner 111 is externally mounted on the door panel 113 of the housing 110. The protective body 10 can be assembled from stainless steel plates. The window 21 is made of transparent plastic or glass, allowing observation of the machining center's working status. The height of the first guide rail 22 and the first slider 115 is higher than the working height of the machining center's cutting head, so that the cutting chips will not fall onto the first slider 115 and the first guide rail 22. The second guide rail 16 is suspended inside the protective body 10. The cutting chips from the machining center will fall onto the pedal 114, and the second guide rail 16 will not accumulate chips, so it does not need to be cleaned. The chips on the pedal 114 are very easy to clean; regular cleaning is sufficient. The end of the second guide rail 16 extends into the relief groove 17, allowing the sliding door 20 to move back and forth within the relief groove 17. The relief groove 17 can control the movement trajectory of the sliding door 20, preventing it from deviating. In addition, the pulley 23 moves along the second guide rail 16, which also cleans the second guide rail 16. Even better, a brush is provided on the side of the pulley 23, which can clean the second guide rail 16 when the pulley 23 moves. A handle 25 is provided on the sliding door for easy opening and closing. The first guide rail 22 is preferably a cylindrical guide rail.

[0034] Preferably, the inner side of the protective body 10 is provided with a plurality of mounting seats 15, and the second guide rail 16 is suspended from the side of the mounting seat 15. The structure of the mounting seat 15 is one of L-shaped, strip-shaped, or U-shaped. The mounting seat 15 can be set on the inner wall of the protective body 10 by screws or clips. In this embodiment, the structure of the mounting seat 15 is U-shaped, and the second guide rail 16 is fixed to the mounting seat 15 by screws. The mounting seats 15 are arranged at intervals, which also helps to allow waste to fall from the second guide rail 16 onto the pedal 114.

[0035] Preferably, the second guide rail 16 is one of the following: a T-shaped guide rail, an L-shaped guide rail, a hollow guide rail, a triangular guide rail, a rectangular guide rail, a dovetail guide rail, a circular guide rail, and a V-shaped guide rail. In this embodiment, the second guide rail 16 is a V-shaped guide rail, and the pulley 23 is also a V-shaped pulley 23. The second guide rail 16 and the pulley 23 are mutually compatible. This structure is a self-cleaning structure, meaning that the second guide rail 16 does not require cleaning, and no debris will fall onto the second guide rail 16.

[0036] Preferably, the inner side of the sliding door 20 is provided with a mounting frame 24, and the window 21 is embedded in the mounting frame 24. The mounting frame 24 is made of stainless steel profile or tubing. The mounting frame 24 is fixed to the inner side of the sliding door 20 with screws. The window 21 can be assembled to the mounting frame 24 by glue or screws.

[0037] Preferably, a mounting bracket 18 is provided at the top of the sliding door 20, and the first guide rail 22 is disposed on the mounting bracket 18; a limiting part 19 is provided at the end of the mounting bracket 18, which can be stopped by the first slider 115, thereby limiting the opening and closing range of the sliding door. The limiting part 19 is formed by bending from the mounting bracket 18, and the structure of the limiting part 19 is L-shaped.

[0038] Preferably, the protective body 10 includes a first side plate 11 and a second side plate 13, which are connected together. A first reinforcing rib 12 is provided on the inner side of the first side plate 11, and a second reinforcing rib 14 is provided on the inner side of the second side plate 13. Both the first and second side plates 11 are made of stainless steel. The first reinforcing rib 12 connects the first side plate 11 together, and the second reinforcing rib 14 connects the second side plate 13 together. Stainless steel sheets or profiles are used to connect the first and second side plates 11 and 13. The first reinforcing rib 12 is formed by bending from the first side plate 11, and the second reinforcing rib 14 is formed by bending from the second side plate 13. This design reduces the overall weight of the protective structure and makes assembly very convenient.

[0039] Preferably, the second side panel 13 forms a chassis 110, and the door panel 113 of the chassis 110 is fixed to the chassis 110 with screws or clips. A partition 112 is provided on the second side panel 13, and the partitions 112 are spliced ​​together to form the chassis 110. An air conditioner 111 is externally mounted on the door panel 113, and the air conditioner 111 cools the equipment inside the chassis 110 to ensure the normal operation of the equipment.

[0040] Preferably, the sliding doors 20 are secured together by latches or magnets, ensuring they remain closed and do not come loose. Even better, the sliding doors 20 are equipped with an interlocking switch connected to the industrial control host. When the sliding doors 20 are opened, the machining center automatically pauses operation to ensure personnel safety.

[0041] Preferably, the bottom of the sliding door 20 is provided with at least two pulleys 23, and the length of the first slider 115 is greater than twice the cross-sectional thickness of the first guide rail 22. The number of pulleys 23 can be set as needed. The first guide rail 22 is preferably a circular guide rail. The length of the first slider 115 is at least twice the diameter or width of the first guide rail 22, and this proportional configuration allows the sliding door 20 to move more smoothly.

[0042] In summary, the key design feature of this invention is that the waste chips generated during cutting fall from top to bottom, preventing them from landing on the first guide rail 22 or the first slider 115. Simultaneously, since the second guide rail 16 is suspended, the waste chips fall directly from the side of the second guide rail 16 into the pedal 114, eliminating the need for track cleaning. Therefore, the sliding door 20 will not experience any jamming issues even after prolonged use, and opening is extremely smooth.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
