Description

Technical Field

[0001] This utility model mainly relates to the field of laser cutting equipment technology, specifically a positioning and lifting device for laser cutting equipment. Background Technology

[0002] Currently, when processing long aluminum profile tubes in a cutting and machining center, an internal support clamp is usually used at the feeding end. This involves inserting a slot corresponding to the shape of the aluminum profile tube into the tube and spreading it open to hold the aluminum profile in place. However, due to the excessive length and weight of the aluminum profile tube, it is difficult to ensure its stability during the cutting process by relying solely on the clamping at the feeding end. Therefore, a lifting device needs to be installed between the feeding end and the laser head processing end. After the aluminum profile tube is supported by the clamp, the lifting device rises and supports the tube from the middle position to prevent the tube from sagging or swaying due to its own weight.

[0003] However, the lifting device in the positioning and lifting device of existing laser cutting equipment is generally fixed. In the actual cutting process, when the first part of the cutting is completed and the feeding end moves the aluminum profile tube towards the laser head processing end, the lifting device will deviate from the middle position of the aluminum profile tube, causing the support position of the aluminum profile tube to change. The inaccuracy of the support position will directly affect the cutting accuracy and quality of the aluminum profile tube, increase the scrap rate, reduce production efficiency, and may also damage the cutting equipment, increasing equipment maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing large-scale aluminum profile laser cutting processes, where the lifting device cannot always be accurately positioned in the middle of the tube due to the excessive length and weight of the aluminum profile tube, thus affecting cutting accuracy and quality, increasing scrap rate, and raising equipment maintenance costs. Therefore, this invention proposes a positioning and lifting device for laser cutting equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning and lifting device for laser cutting equipment includes a support platform. A first screw and a second screw are provided on the support platform. A spur gear is fixedly connected to one end of each of the first and second screws. A gear belt is sleeved on the outer surface of the two spur gears. A clamping mechanism and a supporting mechanism are respectively provided on the first and second screws. The thread pitch on the first screw is set to be twice the thread pitch on the second screw. When the first screw drives the pipe on the clamping mechanism to move, the supporting mechanism on the second screw is always located in the middle position of the pipe.

[0007] As a further description of the above technical solution, the support platform has two first elongated holes and a second elongated hole at both ends. The first screw and the second screw are respectively rotatably installed in one of the first elongated holes and the second elongated hole. The ends of the first screw and the second screw near the spur gear both pass through the support platform. The support platform has a through hole above the second screw. The support platform has a fixing plate at the lower end of the through hole. A first motor is fixedly installed on the fixing plate. The output end of the first motor passes through the fixing plate. Bevel gears are fixedly installed on both the output end of the first motor and the second screw. The two bevel gears mesh with each other.

[0008] As a further description of the above technical solution, the clamping mechanism includes a movable plate slidably mounted on a support platform, a first screw passing through the movable plate and threadedly connected to the movable plate, an elongated rod on the movable plate, a housing on the elongated rod, and four clamping blocks inside the housing. The four clamping blocks are evenly spaced along the outer surface of the housing, and all four clamping blocks pass through the housing and are slidably connected to it.

[0009] As a further description of the above technical solution, a cylinder is fixedly installed on the housing, the output end of the cylinder passes through the housing and is fixedly connected to a support block, a slot is provided on the side of the clamping block near the housing, a transmission rod is provided between the slot and the support block, and the two ends of the transmission rod are respectively hinged to the slot and the support block.

[0010] As a further description of the above technical solution, the support mechanism includes a movable block slidably mounted in a second elongated hole, a second screw passing through the movable block and threadedly connected to the movable block, a lead screw rotatably mounted on the movable block, a second motor fixedly mounted at the lower end of the movable block, the output end of the second motor passing through the movable block and fixedly connected to the lead screw, and a support rod sleeved on the lead screw, and the support rod threadedly connected to the lead screw.

[0011] As a further description of the above technical solution, the movable block is provided with a sliding rod, and a U-shaped limiting rod is fixedly connected to the support rod, and the sliding rod is slidably installed inside the limiting rod.

[0012] As a further description of the above technical solution, a first fixing rod is fixedly installed in another first elongated hole, and a second fixing rod is fixedly installed in the second elongated hole. The first fixing rod passes through the moving plate and is slidably connected to the moving plate, and the second fixing rod passes through the moving block and is slidably connected to the moving block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, by setting the thread pitch on the first screw to twice that on the second screw, the support mechanism on the second screw can always be accurately positioned in the middle of the pipe when the first screw drives the clamping mechanism to move the pipe. This effectively avoids pipe swaying or shifting due to inaccurate support position, thus ensuring the precision of laser cutting and making the cut aluminum profiles more accurate in size, meeting the requirements of high-precision processing. Furthermore, since the support mechanism is always positioned in the middle of the pipe, it provides stable support for the pipe, enhancing the stability of the pipe throughout the cutting process. Even when processing long aluminum profile pipes, it can ensure their stability during the cutting process, reducing equipment failures or processing accidents that may be caused by pipe instability, and improving the safety and stability of processing.

[0022] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0023] Please refer to the appendix carefully. Figures 1-4 As shown, this utility model provides a technical solution: a positioning and lifting device for laser cutting equipment, including a support platform 10. The support platform 10 is provided with a first screw 20 and a second screw 21. One end of the first screw 20 and the second screw 21 are fixedly connected to a spur gear 28. The outer surface of the two spur gears 28 is fitted with a gear belt 29. The first screw 20 and the second screw 21 are respectively provided with a clamping mechanism and a supporting mechanism. The thread pitch on the first screw 20 is set to be twice the thread pitch on the second screw 21. When the first screw 20 drives the pipe on the clamping mechanism to move, the supporting mechanism on the second screw 21 is always located in the middle position of the pipe. Through the transmission cooperation of the two spur gears 28 and the gear belt 29, the first screw 20 and the second screw 21 can rotate synchronously.

[0024] Specifically, by setting the thread pitch on the first screw 20 to twice the thread pitch on the second screw 21, when the first screw 20 drives the clamping mechanism to move the pipe, the support mechanism on the second screw 21 can be accurately positioned in the middle of the pipe, thereby effectively avoiding the pipe shaking caused by the offset of the support position, ensuring the accuracy of the laser cutting path, and thus ensuring that the dimensional error of the cut aluminum profile is extremely small when cutting large aluminum profile pipes, achieving high-precision processing standards and meeting the industrial production needs with extremely high cutting precision requirements;

[0025] The support mechanism is always positioned in the middle of the pipe, providing uniform and stable support force. During the cutting process, even when facing long aluminum profile pipes, it can effectively resist the instability caused by the weight of the pipe itself and the cutting force, keeping the pipe stable throughout the cutting process. This improves the cutting quality, reduces the additional impact on the cutting equipment caused by pipe shaking, and extends the service life of the equipment.

[0026] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the support platform 10 has two elongated holes 101 and 102 at its two ends. The first screw 20 and the second screw 21 are rotatably installed in one of the first elongated holes 101 and 102, respectively. The ends of the first screw 20 and the second screw 21 near the spur gear 28 both pass through the support platform 10. The support platform 10 has a through hole 103 above the second screw 21. The support platform 10 has a fixing plate 104 at the lower end of the through hole 103. The fixing plate 104 has a first motor 14 fixedly installed on it. The output end of the first motor 14 passes through the fixing plate 104. Both the output end of the first motor 14 and the second screw 21 have bevel gears 13 fixedly installed on them. The two bevel gears 13 mesh with each other. The first motor 14 drives the bevel gears 13 connected to the output end of the first motor 14 to rotate. Through the transmission of the bevel gears 13 on the second screw 21, the second screw 21 is driven to rotate.

[0027] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the clamping mechanism includes a movable plate 26 slidably mounted on the support platform 10, a first screw 20 passing through the movable plate 26 and threadedly connected to the movable plate 26, an elongated rod 27 on the movable plate 26, a housing 271 on the elongated rod 27, and four clamping blocks 30 inside the housing 271. The four clamping blocks 30 are evenly spaced along the outer surface of the housing 271, and all four clamping blocks 30 pass through the housing 271 and are slidably connected to it.

[0028] The outer sides of the four clamping blocks 30 are provided with anti-slip textures. The anti-slip textures on the outer sides of the clamping blocks 30 contact the inner wall of the aluminum profile tube to increase friction and prevent the clamping blocks 30 from shifting away from the aluminum profile tube when it is pushed to move. This achieves stable clamping and fixing of the aluminum profile tube. By having the four clamping blocks 30 extend out from the four directions of the housing 271 at the same time, the four clamping blocks 30 can be brought close to the inner wall of the aluminum profile tube to clamp and fix the aluminum profile tube.

[0029] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a cylinder 33 is fixedly installed on the housing 271. The output end of the cylinder 33 passes through the housing 271 and is fixedly connected to a support block 31. A slot 301 is provided on the side of the clamping block 30 near the housing 271. A transmission rod 32 is provided between the slot 301 and the support block 31. The two ends of the transmission rod 32 are hinged to the slot 301 and the support block 31, respectively.

[0030] In detail, when clamping and fixing the aluminum profile tube, the cylinder 33 is activated, causing the cylinder 33 to pull the support block 31 to slide inside the housing 271. The transmission rod 32, which is hinged to the support block 31, also moves accordingly. Since the other end of the transmission rod 32 is hinged to the slot 301 on the clamping block 30, the movement of the transmission rod 32 will drive the clamping block 30 to slide outward along the outer surface of the housing 271, so that the four clamping blocks 30 extend out of the housing 271 at the same time until they are close to the inner wall of the aluminum profile tube. Since the four clamping blocks 30 are evenly spaced along the outer surface of the housing 271, they will clamp the aluminum profile tube evenly.

[0031] In one embodiment of this utility model, such as Figure 3 As shown, the support mechanism includes a movable block 22 slidably mounted in the second elongated hole 102, a second screw 21 passing through the movable block 22 and threadedly connected to the movable block 22, a lead screw 23 rotatably mounted on the movable block 22, a second motor 24 fixedly mounted at the lower end of the movable block 22, the output end of the second motor 24 passing through the movable block 22 and fixedly connected to the lead screw 23, and a support rod 25 sleeved on the lead screw 23, and the support rod 25 threadedly connected to the lead screw 23.

[0032] The second motor 24 drives the lead screw 23 to rotate. A support rod 25 is sleeved on the lead screw 23 and the two are threaded together. When the second motor 24 drives the lead screw 23 to rotate, the support rod 25 can move up and down along the lead screw 23, thereby adjusting the height of the support rod 25 to adapt to pipes of different diameters or different placement states, providing stable support for the pipes, ensuring that the pipes will not shake or shift due to unstable support during the cutting process, and improving the cutting accuracy and quality.

[0033] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the movable block 22 is provided with a sliding rod 221, and the support rod 25 is fixedly connected with a U-shaped limiting rod 251. The sliding rod 221 is slidably installed in the limiting rod 251. Through the limiting action of the limiting rod 251 and the sliding rod 221, when the lead screw 23 rotates, the support rod 25 is prevented from rotating with the lead screw 23, thus preventing it from rising stably.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a first fixing rod 11 is fixedly installed in another first elongated hole 101, and a second fixing rod 12 is fixedly installed in a second elongated hole 102. The first fixing rod 11 passes through the moving plate 26 and is slidably connected to the moving plate 26. The second fixing rod 12 passes through the moving block 22 and is slidably connected to the moving block 22. By setting the first fixing rod 11 and the second fixing rod 12, the moving plate 26 and the moving block 22 can only move along the direction of the first fixing rod 11 and the second fixing rod 12 during the movement, preventing the moving plate 26 and the moving block 22 from shaking or deviating during the movement and exceeding their normal movement range, thereby enhancing the stability and reliability of the entire device.

[0035] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
