Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a modular bed for a laser cutting machine. Background Technology

[0002] Laser cutting machines utilize the laser emitted by a laser, which is focused into a high-power-density laser beam through an optical path system and irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. As the relative position of the beam and the workpiece moves, a kerf is eventually formed, thus achieving the purpose of cutting.

[0003] During laser cutting, a large amount of high-temperature molten slag is generated. Some of this slag splashes onto the spikes at the top of the cutting bed, causing slag accumulation on the spikes. This can hinder the workpiece from being placed flat and affect the cutting effect. Therefore, it is necessary to replace the spikes.

[0004] Currently, manufacturers have developed modular bed frames, which consist of a bed frame and multiple spike modules distributed laterally at the top of the bed frame. Each spike module is secured to the bed frame at both ends along its longitudinal direction using multiple bolts. However, the large number of bolts used to secure the spike modules to the bed frame (typically 6-10) makes the assembly and disassembly of the spike modules cumbersome and reduces efficiency.

[0005] For example, in the patent with publication number CN217224145U, a "modular laser cutting machine conveying platform" is disclosed. In this patent, both ends of the spike module are fixed to the conveying platform (equivalent to a bed frame) by bolts. As can be seen from the attached drawings of the patent, each spike module is fixed to the conveying platform with a total of 6 bolts, which means that the efficiency of assembling and disassembling the spike module needs to be further improved.

[0006] Therefore, how to improve the efficiency of disassembling and assembling spike modules is a technical problem that needs to be solved. Utility Model Content

[0007] To address the aforementioned shortcomings of existing technologies, this invention proposes a modular bed for a laser cutting machine. This invention reduces the number of bolts used to fix the spike modules, thereby improving the efficiency of assembling and disassembling the spike modules.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A modular bed for a laser cutting machine includes a bed frame. Multiple spike modules are laid laterally on the top of the bed frame. Each spike module has a slot and a locking mechanism at both ends along the longitudinal direction. The locking mechanism includes a bracket connected to the bed frame. A bolt is threaded to the top of the bracket, and a slide is horizontally rotatably connected to the bottom of the bolt. A sliding pin is provided at the bottom of the slide and is located in an inclined hole in an inclined plate. A fixing plate is provided at the bottom of the inclined plate and is slidably connected to the bed frame along the longitudinal direction. An insert is provided on the fixing plate and engages with the slot.

[0010] Furthermore, multiple slots are provided laterally, and the number of inserts matches the number of slots.

[0011] Furthermore, the top of the carriage is provided with a rotating hole, the bottom of the bolt is rotatably engaged with the rotating hole in the horizontal plane, the bottom of the bolt is provided with two limiting rings, and the top of the carriage is located between the two limiting rings.

[0012] Furthermore, the top of the bed frame is provided with a guide rail that extends longitudinally, and the bottom of the fixing plate is provided with a dovetail groove, with the guide rail and the dovetail groove slidingly engaged longitudinally.

[0013] Furthermore, the spike module includes two support plates, with a plurality of spike plates arranged laterally between the two support plates. The long side of the spike plates extends longitudinally, and the support plates are provided with the slots.

[0014] Furthermore, the bed frame has a first beam extending longitudinally inside, a second beam extending laterally on top of the first beam, a support groove on top of the second beam, and the bottom of the spiked veneer is inserted into the support groove.

[0015] Furthermore, the top of the bed frame is provided with a step, and the support plate is provided on the step.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this invention, to remove a spike module, only two bolts in the locking mechanism need to be turned downwards; to install a spike module, only two bolts in the locking mechanism need to be turned upwards. Since each locking mechanism has only one bolt, only two bolts need to be turned for each spike module to be removed or installed. Compared with the prior art, this reduces the number of bolts that need to be turned, thus improving the efficiency of removing and installing spike modules.

[0018] 2. In this utility model, when multiple slots are arranged horizontally in the spike module and the same number of inserts are inserted into the slots, the area of ​​the locking mechanism pressing the spike module can be increased, which can improve the stability of the spike module installed on the bed frame.

[0019] 3. In this utility model, the spike module has a simple structure, is easy to process, and is conducive to improving processing efficiency.

[0020] 4. In this utility model, the setting of support groove and step can increase the support area of ​​the spike module, reduce the probability of the spike plate in the spike module sinking, bending and deforming, and improve the stability of the spike module in use.

Therefore, they should not be construed as limitations on this utility model.

[0035] Example:

[0036] See Figure 1 A modular bed for a laser cutting machine includes a bed frame 1 and multiple spike modules 2. In this embodiment, four spike modules 2 are provided, which are laid laterally on top of the bed frame 1.

[0037] See Figure 5 The spike module 2 includes two support plates 21, and a plurality of spike plates 22 distributed laterally are welded and fixed between the two support plates 21. The long side of the spike plates 22 extends longitudinally, and both support plates 21 are provided with a plurality of slots 211 laterally. In this embodiment, there are eleven spike plates 22 located between the two support plates 21, and four slots 211 are provided laterally on each support plate 21.

[0038] See Figure 3 The bed frame 1 has a first beam 11 welded and fixed inside, with its long side extending longitudinally. A second beam 12 is welded and fixed to the top of the first beam 11, with its long side extending laterally. The top of the second beam 12 is provided with support grooves 121, the number of which matches the number of all the spiked veneers 22. Furthermore, a step 13 is provided at the top of the bed frame 1, with its long side extending laterally.

[0039] When the spike module 2 is placed on top of the bed frame 1, the support plate 21 in the spike module 2 rests on the step 13, allowing the support plate 21 to be supported by the step 13. Furthermore, the bottom of the spike plate 22 in the spike module 2 is inserted into the support groove 121, allowing the spike plate 22 to be supported by the support groove 121. Therefore, the step 13 and the support groove 121 increase the support area for the spike module 2, reduce the probability of the spike plate 22 sinking, bending, or deforming, and improve the stability of the spike module 2 in use.

[0040] When the spike module 2 is removed from the top of the bed frame 1, the support plate 21 in the spike module 2 leaves the step 13, and the spike plate 22 in the spike module 2 is pulled out of the support groove 121.

[0041] See Figure 1 The spike module 2 is equipped with locking mechanisms 3 at both ends along the longitudinal direction.

[0042] See Figure 2 and Figure 4 The locking mechanism 3 includes a bracket 31, a bolt 32, a slide 33, a sliding pin 34, an inclined hole plate 35, a fixing plate 36, and an insert block 37. The bracket 31 is welded and fixed to the top of the bed frame 1, and the top of the bracket 31 is threaded with a bolt 32.

[0043] See Figure 7 The top of the slide 33 is provided with a rotating hole 331. The bottom of the bolt 32 rotates and engages with the rotating hole 331 in the horizontal plane. Two limiting rings 321 are welded and fixed to the bottom of the bolt 32. The top of the slide 33 is located between the two limiting rings 321. The two limiting rings 321 are used to prevent the bolt 32 from moving up and down in the rotating hole 331.

[0044] See Figure 4 A sliding pin 34 is welded and fixed to the bottom of the slide 33, and the sliding pin 34 is located in the inclined hole 351 of the inclined hole plate 35. A fixing plate 36 is welded and fixed to the bottom of the inclined hole plate 35, and the bottom of the fixing plate 36 is provided with a dovetail groove 361. A guide rail 14 is welded and fixed to the top of the bed frame 1. The guide rail 14 extends longitudinally and slides longitudinally with the dovetail groove 361. The fixing plate 36 is provided with a plug 37, which is an integral structure with the fixing plate 36, and the number of plugs 37 matches the number of slots 211.

[0045] The working principle of this embodiment is as follows:

[0046] (1) When it is necessary to remove a spike module 2:

[0047] ① See also Figures 10 to 9As the state changes, the worker screws down the bolt 32 in the locking mechanism 3. The bolt 32 causes the slide 33 to move down, and the slide 33 causes the sliding pin 34 to move down. The sliding pin 34 pushes the lower wall of the inclined hole 351, causing the inclined hole plate 35 to move away from the spike module 2. The inclined hole plate 35 causes the fixing plate 36 to leave the spike module 2 together, and the fixing plate 36 causes the insertion block 37 to leave the spike module 2 together, so that the insertion block 37 exits the slot 211 on the spike module 2, releasing the lock on the spike module 2.

[0048] Because locking mechanisms 3 are provided at both ends of the spike module 2, removing one spike module 2 only requires screwing down two bolts 32. Workers can use a manual wrench or an electric wrench to screw down the bolts 32.

[0049] ② See also Figures 9 to 8 Once the state changes, the worker can simply remove the spike module 2 upwards.

[0050] (2) When it is necessary to install a spike module 2:

[0051] ① See also Figures 8 to 9 As the state changes, the worker places the spike module 2 downwards onto the top of the bed frame 1.

[0052] ② See also Figures 9 to 10 As the state changes, the worker rotates the bolt 32 in the locking mechanism 3 upwards. The bolt 32 drives the slide 33 to move upwards, and the slide 33 drives the sliding pin 34 to move upwards. The sliding pin 34 pushes the upper wall of the inclined hole 351, causing the inclined hole plate 35 to move closer to the spike module 2. The inclined hole plate 35 drives the fixing plate 36 to move closer to the spike module 2, and the fixing plate 36 drives the insert block 37 to move closer to the spike module 2, so that the insert block 37 is inserted into the slot 211 of the spike module 2, thereby locking the spike module 2.

[0053] Because locking mechanisms 3 are provided at both ends of the spike module 2, when installing a spike module 2, it is only necessary to screw the two bolts 32 upwards.

[0054] Based on the above working principle, it can be seen that this embodiment has the following effects:

[0055] First, in this embodiment, to remove one spike module 2, only the bolts 32 in the two locking mechanisms 3 need to be turned downwards; to install one spike module 2, only the bolts 32 in the two locking mechanisms 3 need to be turned upwards. Since each locking mechanism 3 has only one bolt 32, only two bolts 32 need to be turned for each spike module 2 to be removed or installed. Compared with the prior art, this reduces the number of bolts 32 that need to be turned, which is beneficial to improving the efficiency of removing and installing spike modules 2.

[0056] Second, in this embodiment, when multiple slots 211 in the spike module 2 are arranged laterally and the same number of inserts 37 are inserted into the slots 211, the area of ​​the locking mechanism 3 pressing the spike module 2 can be increased, which can improve the stability of the spike module 2 installed on the bed frame 1.

[0057] Third, in this embodiment, the spike module 2 has a simple structure, is easy to process, and is conducive to improving processing efficiency.

[0058] 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.
