Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a door opening and closing structure for a laser cutting machine. Background Technology
[0002] In modern manufacturing, laser cutting machines, as high-precision processing equipment, are widely used in aerospace, automobile manufacturing, electronic equipment and many other fields.
[0003] Traditional laser cutting machines often use hinged doors or sliding doors as access channels. However, these two door structures have significant drawbacks in practical applications: Hinged doors rotate and open around the machine frame, creating a fan-shaped area that overlaps with the space required for equipment spacing, making it difficult to achieve high-density equipment deployment in limited workshop space and severely restricting the improvement of site utilization; Sliding doors, although they save some lateral space by sliding in a straight line, require the track to be installed outside the equipment, which not only occupies valuable working area around the equipment, but also the protruding track structure cannot fit tightly with the main body of the equipment, failing to meet the requirements for embedded installation and making it difficult to integrate into the overall production line layout.
[0004] In addition, both traditional door structures cannot completely cover the equipment opening because the door frame, track and other components are external, which makes it easy for dust and debris generated by laser cutting operations to spill out and spread, affecting the workshop environment and posing safety hazards. Moreover, the design of separating the door from the equipment destroys the smoothness and harmony of the overall appearance. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a door opening and closing structure for laser cutting machines, which solves the technical problems that existing laser cutting machines require a large space to open when using hinged doors, while sliding doors need to be deployed outside the equipment, thus failing to meet the requirements for embedded installation.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a door opening and closing structure for a laser cutting machine, comprising a laser cutting machine, wherein a door body is installed on the laser cutting machine, and opening and closing mechanisms connected to the laser cutting machine are provided on both the upper and lower sides of the door body.
[0007] The door opening and closing mechanism includes a door opening and closing guide groove installed on a laser cutting machine, a connector installed on the door body, a slider adapted to the door opening and closing guide groove installed on the connector, a support component to assist the sliding of the door body on the laser cutting machine, buffer components to reduce impact force at both ends of the door opening and closing guide groove, and a dust removal component to collect dust in the groove.
[0008] A further improvement is that the interior of the door guide groove is hollow, and its overall shape is L-shaped, with the L-shaped bend having an arc surface structure.
[0009] A further improvement is that the support assembly includes optical shafts symmetrically mounted on the laser cutting machine, horizontal support rails sliding on the optical shafts, L-shaped connecting channel steels mounted on the door body, rotating shafts mounted on the top of the horizontal support rails and the bottom of the L-shaped connecting channel steels, and a connecting arm mounted between the two sets of rotating shafts.
[0010] A further improvement is that the buffer assembly includes a sleeve installed at the end of the door guide groove, and the sleeve is filled with hydraulic oil. A flexible spring is installed on the inner wall of the sleeve, and a piston rod sliding on the sleeve is installed at the end of the flexible spring. A damping hole is opened on the piston rod, and a rubber impact block is installed at the end of the piston rod.
[0011] A further improvement is that the dust removal assembly includes rubber airbags installed on the inner walls of both sides of the switch door guide groove. The rubber airbags have arrayed exhaust holes that are inclined toward the bottom of the switch door guide groove, and the exhaust holes are tapered holes that are wider inside and narrower outside. A dust collection box is installed on the switch door guide groove.
[0012] A further improvement is that a door handle is installed on the door, and an observation window made of transparent tempered glass is installed on the door.
[0013] By employing the above technical solution, this utility model provides a door opening and closing structure for a laser cutting machine, which has at least the following beneficial effects:
[0014] 1. This utility model allows the door to be pulled open smoothly by connecting the slider along the arc-shaped structure at the corner of the door opening guide groove. Compared with traditional swing doors, this reduces the opening radius and saves the space required for opening. When closing the door, the slider slides along the arc-shaped structure at the corner of the door opening guide groove to complete the inward locking, thus closing flush with the outer wall of the laser cutting machine and achieving embedded installation.
[0015] 2. This utility model connects the horizontal support guide rail and the L-shaped connecting channel steel through the connecting arm, thereby providing auxiliary support for the door body and preventing the door opening and closing guide groove from deforming under stress alone. When the door is opened, the L-shaped connecting channel steel moves with the door body and rotates through the cooperation of the rotating shaft and the connecting arm until the door body is pulled open parallel to the laser cutting machine. At this time, as the slider slides along the door opening and closing guide groove, it pulls the horizontal support guide rail to slide horizontally along the optical axis, thereby improving the stability when opening and closing the door.
[0016] 3. When the slider slides to the end of the switch door guide groove, the slider pushes the rubber block, which pushes the piston rod to slide into the sleeve and squeeze the flexible spring. During this process, the damping hole squeezes the hydraulic oil in the sleeve. The incompressibility of the hydraulic oil and the elasticity of the spring achieve double buffering, thereby avoiding the slider from directly hitting the switch door guide groove and causing damage to the switch door guide groove, and even affecting the overall sealing performance of the laser cutting machine.
[0017] 4. As the slider slides along the door guide groove, it squeezes the rubber airbags on both sides of the door guide groove, and blows the gas inside out at an angle through the exhaust hole. This gradually blows the dust at the bottom of the door guide groove into the dust collection box on one side. The dust in the dust collection box can be removed periodically with a vacuum cleaner. Each time the door is opened, the door guide groove is cleaned, reducing the dust content in the door guide groove and making the door opening and closing smoother. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Example 1
[0035] Addressing the issues of existing laser cutting machines where hinged doors require significant space to open, and sliding doors need to be externally mounted, thus failing to meet the requirements for embedded installation, this embodiment provides a new door structure for laser cutting machines. This structure reduces the opening radius, saves space, and closes flush with the outer wall of the laser cutting machine, achieving embedded installation. Please refer to... Figures 1-7 The laser cutting machine uses a door opening and closing structure, including a laser cutting machine 1, a door body 2 installed on the laser cutting machine 1, and door opening and closing mechanisms 3 connected to the laser cutting machine 1 on both the upper and lower sides of the door body 2. The door opening and closing mechanism 3 reduces the opening radius and saves the space required for opening the door, and closes flush with the outer wall of the laser cutting machine 1 to achieve embedded installation.
[0036] Since the existing laser cutting machine 1 uses a swing door that requires a large space to open, and a sliding door that needs to be deployed outside the equipment, it cannot meet the requirements for embedded installation. Therefore, this device is equipped with a door opening and closing mechanism 3. The door opening and closing mechanism 3 includes a door opening and closing guide groove 31 installed on the laser cutting machine 1, a connector 32 installed on the door body 2, a slider 33 adapted to the door opening and closing guide groove 31 installed on the connector 32, a support component 34 for assisting the sliding of the door body 2 on the laser cutting machine 1, a buffer component 35 for reducing impact force at both ends of the door opening and closing guide groove 31, and a dust removal component 36 for collecting dust in the groove inside the door opening and closing guide groove 31.
[0037] The door guide groove 31 has a hollow structure inside, and its overall shape is L-shaped. The corner of the L-shape is an arc surface structure. When the door body 2 is pulled, the slider 33 is driven by the connector 32 to smoothly open along the arc surface structure at the corner of the door guide groove 31. Compared with the traditional swing door, the opening radius is reduced, saving the space required for opening. When closing the door, the slider 33 slides along the arc surface structure at the corner of the door guide groove 31 to complete the inward snap, thereby closing flush with the outer wall of the laser cutting machine 1, realizing embedded installation.
[0038] Because the door body 2 is relatively heavy, relying solely on the door opening and closing guide groove 31 for support over a long period of time would cause the door opening and closing guide groove 31 to deform, and even lead to the door body 2 falling off. Therefore, the device is also equipped with a support assembly 34. The support assembly 34 includes an optical axis 341 symmetrically mounted on the laser cutting machine 1, a horizontal support guide rail 342 sliding on the optical axis 341, an L-shaped connecting channel steel 343 mounted on the door body 2, and a rotating shaft 344 mounted on the top of the horizontal support guide rail 342 and the bottom of the L-shaped connecting channel steel 343. A connecting arm 345 is installed between the two sets of rotating shafts 344. 345 connects the horizontal support guide rail 342 and the L-shaped connecting channel steel 343, thereby providing auxiliary support for the door body 2 and preventing the door opening and closing guide groove 31 from deforming under stress alone. When the door body 2 slides open in the door opening and closing guide groove 31 via the slider 33, the L-shaped connecting channel steel 343 also moves accordingly. Through the cooperation of the rotating shaft 344 and the connecting arm 345, the door body 2 is pulled open parallel to the laser cutting machine 1. At this time, as the slider 33 slides along the door opening and closing guide groove 31, it pulls the horizontal support guide rail 342 to slide horizontally along the optical axis 341, thereby improving the stability when opening and closing the door.
[0039] When the door 2 is fully opened or closed, the slider 33 will impact the door guide groove 31, causing the laser cutting machine 1 to vibrate. Over time, this will damage the sealing performance at the connection between the laser cutting machine 1 and the door 2. Therefore, the device is also equipped with a buffer assembly 35. The buffer assembly 35 includes a sleeve 351 installed at the end of the door guide groove 31, and the sleeve 351 is filled with hydraulic oil. A flexible spring 352 is installed on the inner wall of the sleeve 351, and a piston rod 353 sliding on the sleeve 351 is installed at the end of the flexible spring 352. The piston rod 353 is provided with damping. A rubber stopper 355 is installed at the end of the piston rod 353 and the hole 354. When the slider 33 slides to the end of the door opening guide groove 31, the slider 33 pushes the rubber stopper 355, which pushes the piston rod 353 to slide into the sleeve 351 and squeeze the flexible spring 352. During this process, the damping hole 354 squeezes the hydraulic oil in the sleeve 351. The incompressibility of the hydraulic oil and the elasticity of the spring are used to achieve double buffering, thereby avoiding the slider 33 from directly hitting the door opening guide groove 31 and causing damage to the door opening guide groove 31, and even affecting the overall sealing performance of the laser cutting machine 1.
[0040] A door handle 41 is installed on the door body 2, and an observation window 42 made of transparent tempered glass is installed on the door body 2. The door can be opened and closed by pulling the door handle 41, and the observation window 42 can be used to observe the processing situation inside the laser cutting machine 1 in real time.
[0041] Example 2
[0042] In a long-term working environment, dust will inevitably accumulate in the door guide groove 31, which will affect the smooth movement of the slider 33. Therefore, based on Embodiment 1, as... Figures 1-7 As shown, the device also includes a dust removal assembly 36, which includes rubber airbags 361 installed on the inner walls of both sides of the door guide groove 31. The rubber airbags 361 have arrayed exhaust holes 362 that are inclined towards the bottom of the door guide groove 31, and the exhaust holes 362 are tapered holes that are wider on the inside and narrower on the outside. A dust collection box 363 is installed on the door guide groove 31. When the door is opened, as the slider 33 slides along the door guide groove 31, it squeezes the rubber airbags 361 on both sides of the door guide groove 31, and blows the gas inside out at an angle through the exhaust holes 362, thereby gradually blowing the dust at the bottom of the door guide groove 31 into the dust collection box 363 on one side. The dust in the dust collection box 363 can be removed periodically by using a vacuum cleaner. The door guide groove 31 is cleaned every time the door is opened, which reduces the amount of dust in the door guide groove 31 and makes the door opening and closing smoother.
