Description

Technical Field

[0001] This utility model relates to the field of laser cutting processing technology, specifically a stable suspension device for processing the body of a laser cutting machine. Background Technology

[0002] A laser cutting machine tool is a precision machining device that uses a high-energy laser beam to cut materials. It generates high temperatures on the material surface through a focused laser beam, causing the material to rapidly evaporate or melt. Assisted gas then blows away the molten material, thus achieving precise cutting. This type of machine tool is widely used in the processing of both metallic and non-metallic materials, and features high cutting speed, high precision, good cut quality, and a high degree of automation.

[0003] Currently, laser cutting machine tool bodies are composed of multiple structures and occupy a large area. Their size and weight cause vibrations during movement. The vibrations generated when the machine tool body moves can be transmitted to the suspension bracket through its structure. Moreover, because the machine tool body is large, its center of gravity changes during movement, which affects the stability of the suspension bracket. Therefore, a stable suspension device for laser cutting machine tool body processing is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stable suspension device for laser cutting machine tool body processing. It has advantages such as improved stability of the suspension support during movement, and solves the problem that vibrations generated when the machine tool body moves can be transmitted to the suspension support through its structure. Furthermore, because the machine tool body is large, its center of gravity changes during movement, which affects the stability of the suspension support.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable suspension device for laser cutting machine bed processing, comprising a base, a support platform, a cutting table, two suspension brackets, a suspension plate, and a drive cutting assembly, wherein the top of the base is provided with a reinforced vibration-resistant structure;

[0006] The reinforced vibration-damping structure includes four reinforced connecting frames fixedly installed between two suspension brackets. Connecting plates are fixedly installed on the outer walls of both sides of the suspension brackets. A side rod is fixedly installed on the side of the connecting plate away from the suspension bracket. A counterweight is fixedly installed on the side rod away from the connecting plate. A rubber plate is fixedly installed on the top outer wall of the counterweight. Four pulleys are rotatably connected inside the counterweight. Two limiting slides are fixedly installed on the top outer wall of the base. Two rubber sleeves are fitted onto the outer wall of the suspension bracket.

[0007] Furthermore, the drive cutting assembly includes an electric slide fixedly installed on the bottom outer wall of the suspension plate. A suspension connecting frame is fixedly installed on the movable shaft of the electric slide. An electric lifting rod is fixedly installed on the bottom outer wall of the suspension connecting frame. A laser cutting seat is fixedly installed on the telescopic shaft of the electric lifting rod. A laser cutting head is fixedly installed on the bottom of the laser cutting seat. Two drive motors are fixedly installed on the front outer wall of the support platform. A threaded rod is fixedly installed on the output shaft of the drive motor. Threaded rings are fixedly installed at both ends of the bottom of the suspension bracket.

[0008] Furthermore, there are four threaded rings, which are threadedly connected to the outer peripheral walls of two threaded rods respectively. The support platform has a sliding groove inside, and the threaded rings and the suspension bracket are slidably connected inside the sliding groove and are of compatible size.

[0009] Furthermore, the reinforcing connecting frame is X-shaped, with four reinforcing connecting frames located between two connecting plates, and the two connecting plates are respectively fixedly installed on the outer walls of the left and right sides of the suspension bracket.

[0010] Furthermore, the side rod is installed at an inclined angle, and the side rod passes through the interior of the rubber plate and is installed on the top of the counterweight.

[0011] Furthermore, the counterweight is slidably connected inside the limiting slide, the limiting slide is U-shaped, and the pulley is slidably connected inside the bottom of the limiting slide.

[0012] Furthermore, the support platform is fixedly installed on the top of the base, the cutting table is fixedly installed on the top of the support platform, the suspension bracket is slidably connected inside the support platform, and the suspension plate is fixedly installed between the two suspension brackets.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This stable suspension device for laser cutting machine tool body processing uses an electric slide, drive motor, threaded rod, threaded ring, and electric lifting rod to move the laser cutting head in the X, Y, and Z directions. The stability of the connection between the two suspension connecting frames is improved by the reinforcement of the connecting frame and the connecting plate. The side rod, counterweight, and pulley achieve a gravity balance effect, which can offset part of the weight of the suspension bracket and the machine tool body it supports. This reduces the burden on the suspension system, reduces swaying and vibration caused by uneven weight distribution, and thus improves the stability of use. Attached Figure Description

[0024] A side rod 16 is fixedly installed on the side of the connecting plate 15 away from the suspension bracket 4. A counterweight 17 is fixedly installed on the side of the side rod 16 away from the connecting plate 15. A rubber plate 18 is fixedly installed on the top outer wall of the counterweight 17.

[0025] The drive cutting assembly includes an electric slide table 6 fixedly installed on the bottom outer wall of the suspension plate 5. A suspension connecting frame 7 is fixedly installed on the movable shaft of the electric slide table 6. An electric lifting rod 8 is fixedly installed on the bottom outer wall of the suspension connecting frame 7.

[0029] The working principle of the above embodiments is as follows:

[0030] The electric slide 6 is started, which drives the laser cutting head 10 to move left and right through the suspension connecting frame 7 for adjustment. At the same time, the electric lifting rod 8 is started to move the laser cutting head 10 upward to adjust the height. Then, the drive motor 11 is started to drive the threaded rod 12 to rotate. At this time, the threaded ring 13 will drive the suspension bracket 4 to move back and forth for adjustment. At this time, the laser cutting head 10 can cut the material. When the suspension bracket 4 moves and works, the rubber sleeve 21 absorbs part of the vibration generated by the suspension bracket 4, reducing the transmission of vibration on the suspension bracket 4. Through the action of the counterweight 17, the effect of gravity balance can be achieved, which can offset part of the weight of the suspension bracket 4 and the machine tool body it supports. This can reduce the burden on the suspension system, reduce the swaying and vibration caused by uneven weight, and thus improve the stability of use.
