Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, and in particular to a shockproof support structure for a lead screw drive. Background Technology
[0002] A cutting machine is a common material cutting device that can quickly cut sheet materials into the required size. Laser cutting mainly relies on the laser moving along a designed trajectory to achieve the cutting of a specified pattern.
[0003] During operation, the working parts of the cutting machine need to move frequently on the working surface, especially the laser-equipped cutting parts. Common methods of moving the cutting parts include belt or lead screw drive to achieve the effect of moving along a specified route. However, lead screw drive has low stability and will vibrate during transmission. The vibration will also intensify as the lead screw lengthens. This will cause the cutting machine to produce certain errors due to vibration during cutting, thus affecting the cutting quality.
[0004] Therefore, a new method is needed to solve the above problems. Utility Model Content
[0005] In order to solve the above problems, this utility model provides a shockproof support structure for screw drive.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a screw-driven anti-vibration support structure, including a movable frame, on which a screw and a laser component are installed. A threaded sleeve that cooperates with the screw is installed inside the laser component. The screw rotates to make the laser component move along the screw. Two anti-vibration blocks are provided on the screw. A stabilizing rod is fixedly connected between the two anti-vibration blocks. The bottoms of the two anti-vibration blocks are slidably connected to the movable frame.
[0007] By adopting the above configuration, two anti-vibration blocks connected to the moving frame restrict the lead screw, thereby achieving a higher degree of integrity between the lead screw and the moving frame. This allows the moving frame to be used to improve the stability of the lead screw and reduce its vibration during operation. At the same time, the anti-vibration blocks can also divide the lead screw into three parts, each with two ends, which to some extent shortens the length of the lead screw, turning the vibration of a long lead screw into the vibration of three short lead screws, thus further weakening the vibration.
[0008] Furthermore: the shock-absorbing block includes a base and a main body, the top of the main body has a notch that mates with the lead screw, and the notch is provided with threads.
[0009] By adopting the above settings, the anti-vibration block not only achieves a closer fit with the lead screw, thereby further enhancing its stability, but also allows the anti-vibration block to move together with the lead screw, thus weakening vibrations in different parts.
[0010] Furthermore: the movable frame is provided with a sliding groove, and the base is provided with a locking block for cooperating with the sliding groove.
[0011] By adopting the above configuration, the sliding groove further ensures the sliding fit between the shock-absorbing block and the moving frame.
[0012] Furthermore, the laser component is installed between the two anti-vibration blocks.
[0013] By adopting the above settings: since the stabilizing rod between the two anti-vibration blocks is fixed, the distance between the two anti-vibration blocks is also fixed, thus the length of the lead screw in the middle section is also fixed, and the vibration generated by it is also fixed. At this time, in addition to the reduction of the vibration of the lead screw by the anti-vibration blocks and the stabilizing rod, the stability of the laser component when moving on the lead screw is greatly guaranteed, thereby ensuring the processing quality of the cutting machine.
[0014] Furthermore, the distance between the two shock-absorbing blocks is greater than 1 / 3 of the length of the lead screw and less than 1 / 2 of the length of the lead screw.
[0015] By adopting the above settings, further limiting the length of the middle section of the lead screw not only ensures that the laser component has sufficient room to move, thus ensuring its flexibility, but also ensures that the length of the middle section of the lead screw is within a reasonable range, preventing excessive vibration due to excessive length, thereby ensuring its stability.
[0016] Compared with the prior art, the advantages of this utility model are:
[0017] By setting anti-vibration blocks at both ends of the stabilizer, the lead screw is effectively divided into three sections, each with at least one end serving as an anti-vibration block. This reduces the impact of increased length on the lead screw's stability. Furthermore, since the laser component is positioned between two anti-vibration blocks, the actual length affecting the laser component is fixed to the distance between the two blocks. Moreover, the anti-vibration blocks are mounted on a movable frame, which further enhances the lead screw's stability, resulting in higher stability for the laser component during lead screw transmission.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1 to 3 As shown, a screw-driven anti-vibration support structure includes a movable frame 1, on which a screw 2 and a laser component are mounted. A threaded sleeve that mates with the screw 2 is installed inside the laser component. Rotation of the screw 2 causes the laser component to move along the screw 2. A motor can be installed at one or both ends of the screw 2. The motor drives the screw 2 to rotate, changing the connection between the screw 2 and the threaded sleeve. This causes the threaded sleeve to move the laser component axially along the screw 2, thus achieving movement of the laser component on the X-axis. The laser component and the screw 2 can then be mounted on a mounting bracket slidably connected to the movable frame 1. The sliding of the mounting bracket achieves movement of the laser component on the Y-axis. The combination of these two components enables the cutting of a set pattern.
[0025] like Figure 1 and Figure 4 As shown, two anti-vibration blocks 21 are provided on the lead screw 2. A stabilizing rod 22 is fixedly connected between the two anti-vibration blocks 21. The bottom of the two anti-vibration blocks 21 is slidably connected to the moving frame 1. The two anti-vibration blocks 21 connected to the moving frame 1 restrict the lead screw 2, so that the lead screw 2 and the moving frame 1 have a higher overall integrity. Thus, the moving frame 1 can be used to improve the stability of the lead screw 2 and reduce its vibration during operation. At the same time, the anti-vibration blocks 21 can also divide the lead screw 2 into three parts, each of which has two ends. To a certain extent, this shortens the length of the lead screw 2, so that the vibration of one long lead screw 2 becomes the vibration of three short lead screws 2, thereby further weakening the vibration.
[0026] like Figure 4As shown, the shock absorber 21 includes a base 211 and a main body 212. The top of the main body 212 has a notch 213 that mates with the lead screw 2. The notch 213 has a thread 214. The shock absorber 21 not only achieves a tighter fit with the lead screw 2, thereby further enhancing its stability, but also allows the shock absorber 21 to move together with the lead screw 2, thus weakening the vibration of different parts. The movable frame 1 has a sliding groove 11, and the base 211 has a locking block 215 for mates with the sliding groove 11. The sliding groove 11 further ensures the sliding fit between the shock absorber 21 and the movable frame 1, and also ensures that the vibration generated by the lead screw 2 can be transmitted to the movable frame 1, and then the stability of the movable frame 1 itself can counteract the vibration, thereby weakening the vibration.
[0027] like Figure 1 As shown, the laser component is installed between two anti-vibration blocks 21. Since the stabilizing rod 22 between the two anti-vibration blocks 21 is fixed, the distance between the two anti-vibration blocks 21 is also fixed, which makes the length of the lead screw 2 in the middle section fixed, and thus the vibration generated by the component is also fixed. In addition, the anti-vibration blocks 21 and the stabilizing rod 22 weaken the vibration of the lead screw 2, thereby ensuring the stability of the laser component when it moves on the lead screw 2, thus ensuring the processing quality of the cutting machine.
[0028] like Figure 1 As shown, the distance between the two anti-vibration blocks 21 is greater than 1 / 3 and less than 1 / 2 of the length of the lead screw 2. Further limiting the length of the middle section of the lead screw 2 not only ensures that the laser component has sufficient room for movement, thus ensuring its flexibility, but also ensures that the length of the middle section of the lead screw 2 is within a reasonable range, so that the vibration will not increase due to excessive length, thereby ensuring its stability.
[0029] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
