Description

Technical Field

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

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting. During the cutting process, the material needs to be placed on a specialized cutting bed.

[0003] In laser cutting, the workpiece is typically placed on a support platform composed of multiple serrated support frames to provide stable support and reduce laser reflection. Existing positioning devices can usually only perform positioning operations at a few fixed points, and these positioning points are mostly located on both sides of the sheet metal. The working principle is mainly to use positioning blocks or clamps on both sides of the sheet metal, aligning the edges of the sheet metal with the positioning blocks or clamping it with the clamps, thereby determining the position of the sheet metal on the support platform. This ensures that the positioning device can only perform positioning operations on precisely oriented sheet metal. Utility Model Content

[0004] The purpose of this invention is to provide a plate positioning device for a laser cutting machine, addressing the problem that existing positioning devices, as mentioned in the background, typically only allow positioning at a few fixed points, and these points are mostly located on the sides of the plate. Its working principle primarily involves setting positioning blocks or clamps on both sides of the plate, fitting the plate's edges against the positioning blocks or clamping them to determine the plate's position on the support platform, thus ensuring that the positioning device can only perform positioning operations on regular plates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plate positioning device for a laser cutting machine, comprising a support platform and a positioning part:

[0006] The support platform has several horizontally arranged support plates for supporting the sheet metal inside. The positioning part is located on the top of the support platform. The positioning part has a positioning frame located on the side of the support plate. A side slider is horizontally slidable inside the positioning frame. The side slider is engaged with the support plate. The side slider is displaced to fix the position of the positioning frame. A sliding rod is provided on the top of the positioning frame. A lower pressure plate is vertically nested and slidably arranged on the side of the sliding rod. A spring b is provided on the top of the lower pressure plate. A top cover is provided on the top of the sliding rod. The spring b is located between the top cover and the lower pressure plate. The bottom surface of the lower pressure plate abuts against the top surface of the sheet metal.

[0007] By adopting the above technical solution, the support plate can be used to stably support the plate. The positioning frame can be fixed in a suitable position by the snap-fit ​​connection between the side slider and the support plate. At the same time, by using the sliding lower pressure plate nested on the slide rod and the spring b, the lower pressure plate can be tightly pressed against the top surface of the plate under the elastic action of the spring b, so as to achieve effective positioning of the plate, prevent the plate from shifting during laser cutting, and ensure cutting accuracy.

[0008] Preferably, the support platform also has a slot formed on the side of the support plate, which engages with the side slider.

[0009] By adopting the above technical solution, the side slider can be accurately engaged with the support plate, which enhances the connection stability between the positioning frame and the support plate.

[0010] Preferably, the positioning part also has a groove formed inside the positioning frame, and the side slider is laterally embedded in the groove and slidably connected to the positioning frame.

[0011] By adopting the above technical solution, the side slider can slide smoothly laterally along the slide groove inside the positioning frame.

[0012] Preferably, there are two side sliders, which are arranged symmetrically in mirror image along the center of the positioning frame. A spring a is provided on the side of each side slider, and the spring a is located in the middle of the two side sliders.

[0013] By adopting the above technical solution, the elasticity of spring a can be used to push the two side sliders to move outward.

[0014] Preferably, the positioning part also has a lifting rod that is vertically slidably disposed inside the positioning frame. The bottom of the lifting rod is provided with a guide groove. A transmission shaft is horizontally disposed inside the side slider. The transmission shaft is embedded in the guide groove and slidably connected to the lifting rod. The top of the guide groove extends outside the positioning frame and is provided with a pressure cap.

[0015] By adopting the above technical solution, the lifting rod can be made to slide vertically inside the positioning frame by pressing the pressure cover. Since the drive shaft is embedded in the guide groove, the vertical sliding of the lifting rod will be converted into the lateral sliding of the side slider in the slide groove through the cooperation of the guide groove and the drive shaft, thereby facilitating the separation of the side slider from the support plate slot.

[0016] Preferably, the positioning part also has a limiting rod disposed on the top of the lower pressure plate, the spring b is nested outside the limiting rod, the limiting rod passes vertically through the top cover and is vertically slidably connected to the top cover.

[0017] By adopting the above technical solution, the spring b can be limited by the limiting rod to prevent the spring b from shifting during compression and extension.

[0018] Preferably, there are four limiting rods, and the four limiting rods are arranged in a central rotational symmetric structure around the center of the positioning frame.

[0019] By adopting the above technical solution, the four limiting rods can limit and guide the lower pressure plate from different directions, ensuring that the movement of the lower pressure plate in the vertical direction is more stable.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: by providing a positioning part, the support plate can be used to stably support the plate. By engaging the side slider with the support plate, the positioning frame can be fixed in a suitable position. At the same time, by using the lower pressure plate nested on the slide rod and the spring b, the lower pressure plate can be tightly pressed against the top surface of the plate under the elastic action of the spring b, thereby achieving effective positioning of the plate and preventing displacement of the plate during laser cutting, thus ensuring cutting accuracy.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a plate positioning device for a laser cutting machine, comprising a support platform 1 and a positioning part 2.

[0031] The support platform 1 has several support plates 101 arranged horizontally inside for supporting the plates. The positioning part 2 is located on the top of the support platform 1. The positioning part 2 has a positioning frame 201 located on the side of the support plate 101. A side slider 205 is slidably arranged horizontally inside the positioning frame 201. The support platform 1 also has a slot 102 opened on the side of the support plate 101. The slot 102 is engaged with the side slider 205, which improves the connection stability between the positioning frame 201 and the support plate 101.

[0032] The positioning frame 201 has a slide rod 203 on its top, and a lower pressure plate 211 is vertically nested and slidably mounted on the side of the slide rod 203. A spring b213 is mounted on the top of the lower pressure plate 211, and a top cover 204 is mounted on the top of the slide rod 203. The spring b213 is located between the top cover 204 and the lower pressure plate 211. The bottom surface of the lower pressure plate 211 abuts against the top surface of the material. The support plate 101 can be used to stably support the material. The positioning frame 201 can be fixed in a suitable position by the engagement of the side slider 205 with the support plate 101. At the same time, the lower pressure plate 211 nested and sliding on the slide rod 203 and the spring b213 can make the lower pressure plate 211 tightly abut against the top surface of the material under the elastic action of the spring b213, thereby achieving effective positioning of the material and preventing displacement of the material during laser cutting, thus ensuring cutting accuracy.

[0033] Example 2

[0034] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a plate positioning device for a laser cutting machine, comprising a positioning part 2, a side slider 205, and a lower pressure plate 211.

[0035] A sliding groove 202 is provided horizontally inside the positioning frame 201. The side slider 205 is horizontally embedded in the sliding groove 202 and slidably connected to the positioning frame 201, so that the side slider 205 can slide smoothly horizontally along the sliding groove 202 inside the positioning frame 201.

[0036] There are two side sliders 205, which are mirror-symmetrically arranged along the center of the positioning frame 201. A spring a207 is provided on the side of the side slider 205. The spring a207 is located in the middle of the two side sliders 205. The elasticity of the spring a207 can be used to push the two side sliders 205 to move outward.

[0037] A lifting rod 208 is vertically slidably installed inside the positioning frame 201. A guide groove 209 is provided at the bottom of the lifting rod 208. A drive shaft 206 is horizontally installed inside the side slider 205. The drive shaft 206 is embedded in the guide groove 209 and slidably connected to the lifting rod 208. The top of the guide groove 209 extends outside the positioning frame 201 and is provided with a pressure cap 210. The lifting rod 208 can be vertically slid inside the positioning frame 201 by pressing the pressure cap 210. Since the drive shaft 206 is embedded in the guide groove 209, the vertical sliding of the lifting rod 208 is converted into the horizontal sliding of the side slider 205 in the slide groove 202 through the cooperation of the guide groove 209 and the drive shaft 206, thereby facilitating the separation of the side slider 205 from the slot 102 of the support plate 101.

[0038] A limit rod 212 is integrally provided on the top of the lower pressure plate 211. The spring b213 is nested outside the limit rod 212. The limit rod 212 passes vertically through the top cover 204 and slides vertically with the top cover 204. The limit rod 212 can be used to limit the spring b213 and prevent the spring b213 from deviating during compression and extension.

[0039] There are four limit rods 212. The four limit rods 212 are arranged in a central rotational symmetry structure around the center of the positioning frame 201, which allows the four limit rods 212 to limit and guide the lower pressure plate 211 from different directions, ensuring that the movement of the lower pressure plate 211 in the vertical direction is more stable.

[0040] Working principle: First, place the plate on the support plate 101 of the support platform 1. When the position of the positioning frame 201 needs to be adjusted, press the cover 210 to make the lifting rod 208 slide vertically downward inside the positioning frame 201. Since the drive shaft 206 is embedded in the guide groove 209, the vertical sliding of the lifting rod 208 will be converted into the lateral sliding of the side slider 205 in the slide groove 202 through the cooperation of the guide groove 209 and the drive shaft 206. At this time, the side slider 205 overcomes the elastic force of the spring a207 and retracts into the positioning frame 201, thereby separating the side slider 205 from the slot 102 on the side of the support plate 101. Then, the positioning frame 201 can be moved to the appropriate position along the arrangement direction of the support plate 101. After reaching the appropriate position, release the cover 210. The elastic force of the spring a207 pushes the two side sliders 205 to move outward, so that the side sliders 205 re-enter the slot 102 on the side of the support plate 101, realizing the positioning of the positioning frame 201. After the positioning frame 201 is fixed in place, the lower pressure plate 211 is nested and slidably arranged on the slide rod 203, and the spring b213 at the top of the lower pressure plate 211 is located between the top cover 204 and the lower pressure plate 211. The elastic action of the spring b213 will make the lower pressure plate 211 tightly abut against the top surface of the plate. At the same time, the four limiting rods 212 with a central rotational symmetry structure around the center of the positioning frame 201 can limit and guide the lower pressure plate 211 from different directions, ensuring that the movement of the lower pressure plate 211 in the vertical direction is more stable, and further ensuring the reliable positioning of the plate by the lower pressure plate 211 on the plate. In this way, the stable support of the plate by the support plate 101, the engagement of the side slider 205 and the slot 102 to fix the position of the positioning frame 201, and the tight abutment of the lower pressure plate 211 against the top surface of the plate under the action of the spring b213, achieve effective positioning of the plate, prevent the plate from shifting during the laser cutting process, and ensure the accuracy of laser cutting.
