Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a laser cutting auxiliary device for door and window production. Background Technology

[0002] Laser cutting refers to the use of a high-power-density laser beam to irradiate the material being cut, which quickly heats the material to its vaporization temperature, causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf, thus completing the cutting of the material.

[0003] However, when lasers cut sheet metal, once the sheet is fixed on the laser cutting machine, it can generally only cut one side of the sheet. This cannot meet the multi-sided cutting requirements of profiles such as angle steel and channel steel. Furthermore, in some factories, sheet metal is still manually loaded onto the laser cutting machine. However, the position of the sheet metal placed manually varies, requiring further adjustment of its angle and position, which is time-consuming and labor-intensive. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a laser cutting auxiliary device for door and window production, which can reduce the clogging of the filter structure and reduce the tedious process of manually disassembling the filter structure for replacement and cleaning.

[0005] The objective of this utility model is achieved through the following technical solution: According to an embodiment of this disclosure, a laser cutting auxiliary device for door and window production is provided, including a base frame and a clamping assembly; The bottom frame is provided with a fixed component and a movable component on its left and right sides respectively. The workpiece is placed on the bottom frame at the position between the fixed component and the movable component. The clamping assembly includes two coaxially arranged clamping structures, which are respectively disposed on the fixed assembly and the movable assembly. The clamping structures are used to abut against the ends of the workpiece. The fixed assembly is fixedly installed on the base frame. The bottom of the front and rear ends of the movable assembly is provided with a first slider, which is movably disposed on a first slide rail. The first slide rail is disposed at the front and rear ends of the base frame and extends in the left and right direction.

[0006] As a preferred embodiment, a first motor is provided on the bottom frame, the output shaft of the first motor extends in the left and right direction, and the output shaft of the first motor is connected to a lead screw through a reduction mechanism. A nut block is threaded onto the lead screw, and the nut block is fixedly connected to the moving component.

[0007] As a preferred embodiment, the fixed component and the moving component have the same structure, both including a box body. A second motor is installed on the side of the box body. The output shaft of the second motor extends in the left-right direction and is connected to the drive gear installed in the box body. The drive gear meshes with the drive rack. The drive rack extends in the front-back direction and is installed on the connecting plate. The bottom of the connecting plate is movably mounted on the second slide rail via a second slider. The second slide rail extends in the front-back direction and is installed in the box body. The connecting plate is also equipped with a driven rack, which meshes with a driven gear. The driven gear is connected to the clamping structure through a transmission shaft.

[0008] As a preferred embodiment, baffles are provided at both ends of the second slide rail inside the housing; and a stop is provided at the end of the driven rack on the connecting plate.

[0009] As a preferred embodiment, the clamping structure includes a base plate, the side of the base plate facing the workpiece is connected to a limiting plate via a buffer spring, and the side of the limiting plate facing the workpiece is provided with an L-shaped limiting member and a limiting structure, and the limiting structure and the L-shaped limiting member define a clamping space for clamping the workpiece.

[0010] As a preferred embodiment, the limiting structure includes a limiting cylinder mounted on the limiting plate. The piston rod of the limiting cylinder points to the angle between the L-shaped limiting member and the limiting pressure block. The clamping space is defined between the limiting pressure block and the L-shaped limiting member.

[0011] As a preferred embodiment, the clamping components are arranged in several groups at intervals along the front-back direction, and each group of clamping components is used to clamp a workpiece.

[0012] As a preferred embodiment, the bottom of the fixing component is connected to the bottom frame via a fixing block.

[0013] In summary, compared with the prior art, this utility model has the following beneficial effects: 1. The distance between the fixed component and the moving component is adjusted by the first motor to accommodate angle steel parts of different lengths; 2. The angle steel workpiece is clamped by a limit cylinder and an L-shaped limit component.

[0016] 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.

[0017] Example: Figures 1 to 6 As shown, a laser cutting auxiliary device for door and window production includes a base frame 1 and a clamping assembly 2; The bottom frame 1 is provided with a fixed component 31 and a movable component 32 on its left and right sides respectively. The workpiece 5 is set on the bottom frame 1 at the position between the fixed component 31 and the movable component 32. The clamping assembly 2 includes two coaxially arranged clamping structures 20, which are respectively disposed on the fixed assembly 31 and the moving assembly 32. The clamping structures 20 are used to abut against the end of the workpiece 5. The fixed assembly 3 is fixedly installed on the bottom frame 1. The bottom of the front and rear ends of the moving assembly 32 is provided with a first slider 41, which is movably disposed on a first slide rail 42. The first slide rail 42 is disposed at the front and rear ends of the bottom frame 1 and extends in the left and right direction.

[0018] Specifically, a first motor 43 is provided on the bottom frame 1. The output shaft of the first motor 43 extends in the left and right direction, and the output shaft of the first motor 43 is connected to the lead screw 45 through the reduction mechanism 44. A nut block 46 is threadedly connected to the lead screw 45, and the nut block 46 is fixedly connected to the moving component 32.

[0019] In practice, the deceleration mechanism 44 can be a gearbox purchased directly from the market.

[0020] In this embodiment, the first motor drives the lead screw to rotate, and the lead screw drives the moving component to move on the first slide rail through the nut, thereby adjusting the distance between the fixed component and the moving component to accommodate angle steel parts of different lengths.

[0021] Specifically, the fixed component 31 and the moving component 32 have the same structure, both including a housing 300. A second motor 301 is installed on the side of the housing 300. The output shaft of the second motor 301 extends in the left-right direction and is inserted into the housing 300. The output shaft of the second motor 301 is connected to the drive gear 302 disposed in the housing 300. The drive gear 302 is meshed with the drive rack 303. The drive rack 303 extends in the front-back direction and is installed on the connecting plate 304. The bottom of the connecting plate 304 is movably disposed on the second slide rail 306 through the second slider 305. The second slide rail 306 extends in the front-back direction and is disposed in the housing 300. The connecting plate 304 is also provided with a driven rack 307, which meshes with a driven gear 308. The driven gear 308 is connected to the clamping structure 20 through the transmission shaft 309.

[0022] In practice, the lead screw 45 is mounted on the base frame via a lead screw support with bearings. This lead screw support can be purchased directly from the market, and the specific structure of the lead screw support is not the subject of this application.

[0023] In this embodiment, the second motor drives the drive gear to rotate. The drive gear is connected to the drive rack through meshing to drive the displacement on the second slide rail on the connecting plate. This causes the driven rack on the second slide rail to drive the driven gear to rotate, thereby causing the clamping structure to rotate and achieving the effect of rotating the angle steel workpiece for cutting and processing the two sides of the angle steel.

[0024] Specifically, baffles 310 are provided at both ends of the second slide rail 306 inside the housing 300; and a stop block 311 is provided at the end of the driven rack 307 on the connecting plate 304.

[0025] In this embodiment, baffles and blocks are used to limit the displacement of the active rack, driven rack, and second slide rail, so as to avoid the situation where the active rack disengages from the active gear and the driven rack disengages from the driven gear due to excessive displacement.

[0026] Specifically, the clamping structure 20 includes a base plate 201. The side of the base plate 201 facing the workpiece 5 is connected to the limiting plate 203 via a buffer spring 202. The side of the limiting plate 203 facing the workpiece 5 is provided with an L-shaped limiting member 204 and a limiting structure 205. The limiting structure 205 and the L-shaped limiting member 204 define a clamping space for clamping the workpiece 5.

[0027] Of course, depending on the actual situation, only the moving component can be equipped with a buffer spring, while the fixed component can be free of buffer springs. In this way, the fixed component is in a relatively stable state. When the angle steel workpiece is loaded into the clamping component, the angle steel workpiece only needs to apply pressure to one side of the moving component and is fixed under the restoring action of the buffer spring, which improves stability.

[0028] Specifically, the limiting structure 205 includes a limiting cylinder 206 mounted on the limiting plate 203. The piston rod 207 of the limiting cylinder 206 points to the angle between the L-shaped limiting member 204 and the piston rod 207 is connected to the limiting pressure block 208. The clamping space is defined between the limiting pressure block 208 and the L-shaped limiting member 204.

[0029] In this embodiment, the displacement of the limiting pressure block is controlled by the piston rod of the limiting cylinder to adjust the size of the clamping space, thereby achieving the clamping of the angle steel workpiece.

[0030] Specifically, the bottom of the fixing component 31 is connected to the bottom frame 1 via a fixing block 47.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
