Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a laser processing device. Background Technology

[0002] Currently, small and medium-sized desktop laser processing equipment has an enclosed processing space at the front of the machine. During processing, the object to be processed is placed on the processing table. Therefore, the size of the object is limited by the processing table or processing space. When processing long and narrow objects, the object cannot be placed due to the limited processing space, thus making processing impossible. Therefore, there is a need to design a laser processing equipment that can temporarily process long and narrow objects. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a laser processing device that can temporarily change the processing space, making it convenient for processing long and narrow objects.

[0004] A laser processing device includes a body with a processing space in the middle. The processing space has a notch in the middle of its rear side, which extends rearward to form an extension space. The rear side of the extension space has a rear connecting plate that is detachably connected to the body. The upper end of the front side wall of the processing space has an opening, and a cover is provided above the processing space. One end of the cover is rotatably connected to the body, and the other end of the cover abuts against the lower end face of the opening.

[0005] Furthermore, the lower end of the opening is provided with an intermediate plate that is rotatably connected to the machine body or detachably connected to the machine body.

[0006] Furthermore, a lower side plate is provided below the middle plate, and a rotating connection structure connects the middle plate and the lower side plate.

[0007] Furthermore, at least one end of the intermediate plate is provided with a connection structure between it and the body, and the intermediate plate is connected to the body through the connection structure.

[0008] Furthermore, the front ends of the two side walls of the opening are respectively recessed to form concave holes that cooperate with the end of the intermediate plate. The connecting structure is provided between the front end face of the concave hole and the intermediate plate. When the end of the intermediate plate enters the concave hole, the intermediate plate is connected to the machine body through the connecting structure.

[0009] Furthermore, the connection structure includes a push-button door lock, with the fixing part of the push-button door lock disposed on the front end face of the recess, and the locking part of the push-button door lock disposed on the end of the intermediate plate.

[0010] Furthermore, the processing space is equipped with a processing table, which is connected to a lifting mechanism. The lifting mechanism includes lead screws located at the four corners of the processing space. The lead screws are threadedly connected to nut blocks, which are connected to the processing table. The lead screws are rotatably connected to the machine body. The lead screws are fitted with synchronous pulleys, and all synchronous pulleys are connected by a synchronous belt. The synchronous belt is connected to a drive synchronous pulley, which is connected to a drive motor.

[0011] Furthermore, a handle is attached to the middle of the rear connecting plate.

[0012] The beneficial effects of this utility model are as follows: By setting an extension space on the rear side of the processing space and setting a rear connecting plate on the machine body corresponding to the extension space, the long and narrow workpieces can pass through the processing space for processing, the processing space can be temporarily adjusted, and it is convenient to use.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 8 As shown.

[0028] Example 1: See Figure 1 , Figure 2 as well as Figure 3A laser processing device includes a body 10, a processing space 6 in the middle of the body 10, a notch 4 in the middle of the rear side of the processing space 6, the notch 4 extending rearward to form an extension space 8, a rear connecting plate 14 detachably connected to the body 10 in the rear side of the extension space 8; an opening 16 in the upper end of the front side wall of the processing space 6, a cover 1 in the upper part of the processing space 6, one end of the cover 1 being rotatably connected to the body 10, and the other end of the cover 1 abutting against the lower end face of the opening 16.

[0029] Compared with the prior art, the improvements of this technical solution are as follows: 1. An extension space 8 is formed on the rear side of the processing space 6, and the extension space 8 is isolated from the outside by a detachable rear connecting plate 14; 2. An opening 16 is formed on the front side of the processing space 6, preferably, the lower end face of the opening 16 is lower than the upper end face of the extension space 8. During normal operation, the workpiece is placed in the processing space 6, and the cover 1 and the machine body 10 cooperate to enclose the processing space 6, forming a closed space. When it is temporarily necessary to process a long and narrow object, the width of the long and narrow object needs to be less than or equal to the width of the extension space 8 and the width of the processing space 6. At this time, the cover 1 needs to be opened, and if necessary, the rear connecting plate 14 is also opened. The operator puts on protective gear and then inserts the long and narrow object into the processing space 6. One end of the long and narrow object extends into or passes through the extension space 8, and the other end of the long and narrow object can be supported by other support frames or suspended at the opening 16 on the front side of the processing space 6. The cover 1 can be rotatably connected to the machine body 10 by a hinge.

[0030] See Figure 1 , Figure 3 as well as Figure 5 The lower end of the opening 16 is provided with an intermediate plate 5 that is rotatably connected to the body 10 or detachably connected to the body 10.

[0031] When a long, narrow object is required to be fed during processing, it needs to be coordinated with a conveying mechanism, such as a belt conveyor. The long, narrow object is placed on the belt conveyor and conveyed forward by the belt. In order to enable the long, narrow object to enter the worktable in the processing space 6 smoothly, in this embodiment, a middle plate 5 is provided at the lower end of the front opening 16. The middle plate 5 can be rotatably connected to the machine body 10 or detachably connected. If a rotatable connection is used, the middle plate 5 is flipped outward to expose the worktable. If a detachable connection is used, it can be directly removed to expose the worktable.

[0032] See Figure 1 , Figure 3 as well as Figure 5 A lower side plate 17 is provided below the middle plate 5, and a rotating connection structure connects the middle plate 5 and the lower side plate 17.

[0033] To facilitate the rotation of the intermediate plate 5 relative to the body 10, a rotating connection structure is provided between the intermediate plate 5 and the lower side plate 17 in this embodiment. The rotating connection structure can be a hinge 9 or the like; the intermediate plate 5 is flipped over by the hinge 9.

[0034] Of course, other structures can also be used, such as: the lower ends of the middle plate 5 have rotating shafts extending outward on both sides, and the body 10 is provided with shaft holes that cooperate with the rotating shafts, so that the middle plate 5 can rotate relative to the body 10 through the rotating shafts.

[0035] See Figure 5 , Figure 6 At least one end of the intermediate plate 5 is provided with a connection structure between it and the body 10, and the intermediate plate 5 is connected to the body 10 through the connection structure.

[0036] To ensure the intermediate plate 5 remains vertical during normal operation, a connection structure is provided between the end of the intermediate plate 5 and the body 10 in this embodiment. This connection structure can be based on existing technology, such as a snap-fit ​​structure or a plug-in structure. Alternatively, a pin structure can be used, such as a movable pin on the intermediate plate 5 and a socket on the body 10; the intermediate plate 5 is connected to or disconnected from the body 10 by inserting or removing the movable pin into the socket. This is existing technology and will not be described in detail here.

[0037] See Figure 3 , Figure 5 The front ends of the two side walls of the opening 16 are respectively recessed to form recessed holes 11 that cooperate with the end of the intermediate plate 5. The front end face of the recessed hole 11 and the intermediate plate 5 are provided with the aforementioned connecting structure. When the end of the intermediate plate 5 enters the recessed hole 11, the intermediate plate 5 is connected to the body 10 through the connecting structure.

[0038] To facilitate the connection between the intermediate plate 5 and the body 10, and to ensure that the intermediate plate 5 does not interfere with the side wall, a recessed hole 11 is provided at the front end of the side wall of the opening 16 in this embodiment. The recessed hole 11 is used to accommodate the end of the intermediate plate 5. At the same time, a connecting structure is provided between the front end face of the recessed hole 11 and the intermediate plate 5, so that the intermediate plate 5 can be connected or separated from the body 10 through the connecting structure. The connecting structure can be Velcro, such as: the hook part of Velcro is glued to the end of the intermediate plate 5, and the thread part of Velcro is provided on the front end face of the recessed hole 11.

[0039] See Figure 6 The connection structure includes a push-button door lock, with the fixing part 13 of the push-button door lock disposed on the front end face of the recess 11, and the locking part 12 of the push-button door lock disposed on the end of the intermediate plate 5.

[0040] The push-button door lock allows for easy flipping of the middle plate 5 and connection to the body 10.

[0041] See Figure 2The processing space 6 is equipped with a processing table 2, which is connected to a lifting mechanism. The lifting mechanism includes lead screws 3 located at the four corners of the processing space 6. The lead screws 3 are threadedly connected to nut blocks 7, which are connected to the processing table 2. The lead screws 3 are rotatably connected to the machine body 10. The lead screws 3 are fitted with synchronous pulleys, and all synchronous pulleys are connected by a synchronous belt. The synchronous belt is connected to a drive synchronous pulley, which is connected to a drive motor (not shown in the figure).

[0042] To facilitate workpiece processing, the internal processing table 2 is raised and lowered via a lifting mechanism to adjust the height of the workpiece. Specifically, connecting blocks are attached to the four corners of the processing table 2, and these connecting blocks are fixed to the nut blocks 7 with bolts. Lead screws 3 are connected to the machine body 10 via bearings, allowing them to rotate relative to the machine body 10. Lead screws 3 are connected to a drive motor via a synchronous belt mechanism. The drive motor drives all lead screws 3 to rotate together, maintaining consistent rising and falling motion, thus ensuring the stability of the worktable. When processing long and narrow objects, the height of the worktable needs to be adjusted so that the end of the object can enter or extend into the extension space 8. The synchronous belt, synchronous pulley, and drive motor constitute the synchronous belt drive mechanism, which can be existing technology and will not be described in detail here.

[0043] See Figure 7 A handle 15 is connected to the middle of the rear connecting plate 14.

[0044] The handle 15 is provided to assist in the installation and removal of the rear connecting plate 14.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
