Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically a clamping device for sheet metal laser cutting. Background Technology

[0002] Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density laser beam through an optical system. The laser beam then irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point, thus completing the cutting process. Before cutting sheet metal, it is necessary to fix the sheet metal in place to facilitate subsequent laser cutting processing.

[0003] Existing sheet metal laser cutting equipment mostly uses two clamping plates to hold and fix the outer wall of the sheet metal pipe when cutting it. Since the surface of the sheet metal pipe is relatively smooth, the sheet metal pipe is prone to axial sliding during cutting, which causes deviation in the cutting area, resulting in offset of the cut and reduced cutting quality.

[0004] Therefore, a clamping device for sheet metal laser cutting is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a clamping device for sheet metal laser cutting to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A clamping device for sheet metal laser cutting includes: a processing table, a support frame fixedly installed on the top surface of the processing table, a moving device movably installed on the bottom surface of the support frame, and a laser cutting device fixedly installed on the bottom surface of the moving device;

[0008] A fixing mechanism is provided above the processing table. The fixing mechanism includes an arc-shaped frame located above the processing table for clamping and fixing the workpiece.

[0009] A clamping mechanism is provided on both sides of the fixing mechanism. The clamping mechanism includes an arc plate located on one side of the arc frame. Two fixing blocks are fixedly installed on the side of the arc plate for pressing and fixing the two ends of the workpiece.

[0010] Preferably, the top surface of the processing table is provided with a movable groove, and two support plates are slidably connected to the inner wall of the movable groove. Support rods are fixedly installed on the top surfaces of the two support plates by bolts. Multiple arc-shaped frames are provided, and the two ends of the two support rods are fixedly connected to the outer walls of the multiple arc-shaped frames respectively.

[0011] Preferably, the two support plates are respectively provided with threaded holes on their sides, a motor is fixedly installed on the side of the processing table, a bidirectional lead screw is fixedly installed at the output end of the motor, the other end of the bidirectional lead screw is rotatably extended through the side of the processing table into the interior of the moving groove via a first bearing seat, one end of the bidirectional lead screw is rotatably connected to the inner wall of one side of the moving groove via a second bearing seat, and the outer wall of the bidirectional lead screw is threadedly connected to the inner walls of the two threaded holes.

[0012] Preferably, the top surfaces of both ends of the support rod are provided with grooves, the inner walls of the grooves are slidably connected with movable blocks, the movable blocks are fixedly installed on both sides, the inner walls of the two grooves are provided with limiting grooves, and the inner walls of the two limiting grooves are slidably connected to the outer walls of the two limiting blocks respectively.

[0013] Preferably, the side of the movable block is elastically connected to the inner wall of the tank via a spring, and a push plate is fixedly installed on the other side of the movable block. A through hole is provided through the inner wall of the arc-shaped frame. One end of the push plate slides through the inner wall of the tank and extends into the arc-shaped frame. The outer wall of the push plate is slidably connected to the inner wall of the through hole.

[0014] Preferably, two hinge blocks are fixedly installed on the outer wall of the arc-shaped frame, and adjusting rods are respectively hinged to the inner walls of the two hinge blocks. The two adjusting rods are fixedly connected to the side of the fixed block.

[0015] Preferably, fixed rods are fixedly installed on the upper and lower sides of the two movable blocks respectively, and adjustment grooves are opened through the top surfaces of the two adjustment rods respectively. The inner walls of the two adjustment grooves are slidably connected to the outer walls of the two fixed rods respectively, and circular plates are fixedly installed on the other ends of the two fixed rods respectively.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] When the sheet metal of the pipe is clamped and fixed by the arc frame, the outer wall of the sheet metal of the pipe is pressed and moved by the push plate. The push plate drives the moving block to move and presses the spring. When the moving block drives the fixed rod to move, it slides in the adjustment groove, thereby driving the adjustment rod to rotate. The other end of the adjustment rod drives the fixed block and the arc plate to move. The arc plate presses and fixes the edges of both ends of the sheet metal of the pipe. This makes it less likely for axial movement to occur during the cutting of the sheet metal of the pipe, thus ensuring the accuracy of the cutting and improving the cutting quality.

[0018] By turning on the motor, the bidirectional lead screw is driven to rotate. When the bidirectional lead screw rotates, it causes the two support plates to move closer to each other. The two support plates then move the two support rods, which in turn move the two arc-shaped frames closer to each other to clamp and fix the outer wall of the sheet metal fitting. This makes the sheet metal fitting less likely to move during processing and improves the processing quality. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figure 1-5 As shown, this application provides a clamping device for sheet metal laser cutting, including: a processing table 1, a support frame 101 fixedly installed on the top surface of the processing table 1, a moving device 102 movably installed on the bottom surface of the support frame 101, and a laser cutting device 103 fixedly installed on the bottom surface of the moving device 102.

[0031] The fixing mechanism 2 is set above the processing table 1. The fixing mechanism 2 includes an arc-shaped frame 205 located above the processing table 1, which is used to clamp and fix the workpiece.

[0032] Specifically, such as Figure 1-4 As shown, a movable groove 201 is provided on the top surface of the processing table 1. Two support plates 202 are slidably connected to the inner wall of the movable groove 201. Support rods 204 are fixedly installed on the top surface of the two support plates 202 by bolts. Multiple arc-shaped frames 205 are provided. The two ends of the two support rods 204 are fixedly connected to the outer wall of the multiple arc-shaped frames 205 respectively.

[0033] In this embodiment: the support plate 202 is limited by the moving groove 201 to ensure that the movement of the support plate 202 is more stable. The support rod 204 and the arc frame 205 can be used to fix the sheet metal of the pipe fittings conveniently and quickly.

[0034] Specifically, such as Figure 1-4 As shown, threaded holes are respectively opened through the sides of the two support plates 202. A motor 203 is fixedly installed on the side of the processing table 1. A bidirectional lead screw 206 is fixedly installed at the output end of the motor 203. The other end of the bidirectional lead screw 206 extends through the side of the processing table 1 to the inside of the moving groove 201 through the first bearing seat. One end of the bidirectional lead screw 206 is rotatably connected to the inner wall of one side of the moving groove 201 through the second bearing seat. The outer wall of the bidirectional lead screw 206 is threadedly connected to the inner wall of the two threaded holes.

[0035] In this embodiment: by turning on the motor 203, the bidirectional lead screw 206 is driven to rotate. The bidirectional lead screw 206 drives the two support plates 202 to move closer or further apart, thereby driving the arc frame 205 to fix and remove the sheet metal of the pipe.

[0036] The clamping mechanism 3 is set on both sides of the fixing mechanism 2. The clamping mechanism 3 includes an arc plate 314 located on one side of the arc frame 205. Two fixing blocks 313 are fixedly installed on the side of the arc plate 314 for pressing and fixing the two ends of the workpiece.

[0037] Specifically, such as Figure 1-5 As shown, grooves 301 are provided on the top surfaces of both ends of the support rod 204. A moving block 302 is slidably connected to the inner wall of the groove 301. Limiting blocks 303 are fixedly installed on both sides of the moving block 302. Limiting grooves 304 are provided on the inner walls of both sides of the groove 301. The inner walls of the two limiting grooves 304 are slidably connected to the outer walls of the two limiting blocks 303 respectively.

[0038] In this embodiment: the moving block 302 is initially limited by the groove 301, and the moving block 302 is further limited by the limiting groove 304 and the limiting block 303, so that the moving block 302 moves more smoothly.

[0039] Specifically, such as Figure 1-5 As shown, the side of the movable block 302 is elastically connected to the inner wall of the groove 301 by a spring 305. A push plate 306 is fixedly installed on the other side of the movable block 302. A through hole 307 is opened through the inner wall of the arc frame 205. One end of the push plate 306 slides through the inner wall of the groove 301 and extends into the arc frame 205. The outer wall of the push plate 306 is slidably connected to the inner wall of the through hole 307.

[0040] In this embodiment: when the tubular sheet metal is clamped and fixed by the arc frame 205, the outer wall of the tubular sheet metal is pressed and moved against the push plate 306, and the push plate 306 drives the moving block 302 to move, thus promoting the transmission of the subsequent structure.

[0041] Specifically, such as Figure 1-5 As shown, two hinge blocks 308 are fixedly installed on the outer wall of the arc frame 205. Adjusting rods 309 are respectively hinged to the inner walls of the two hinge blocks 308. The two adjusting rods 309 are fixedly connected to the side of the fixed block 313.

[0042] In this embodiment: by rotating the adjusting rod 309, the fixing block 313 and the arc plate 314 are driven to rotate to press and fix the edges of both ends of the pipe sheet metal, so that the pipe sheet metal is not easy to move during processing, thus improving the processing quality.

[0043] Specifically, such as Figure 1-5 As shown, two moving blocks 302 are fixedly mounted with fixed rods 311 on their upper and lower sides respectively. Two adjusting rods 309 are respectively provided with adjusting grooves 310 through their top surfaces. The inner walls of the two adjusting grooves 310 are slidably connected to the outer walls of the two fixed rods 311 respectively. The other ends of the two fixed rods 311 are respectively fixedly mounted with circular plates 312.

[0044] In this embodiment: the push plate 306 drives the moving block 302 to move, the moving block 302 drives the fixed rod 311 to move, the fixed rod 311 moves on the inner wall of the adjusting groove 310 and drives the adjusting rod 309 to rotate, thereby driving the arc plate 314 to rotate and fix the two ends of the pipe sheet metal.

[0045] Specifically, the solution is as follows: The motor 203 is turned on, driving the bidirectional lead screw 206 to rotate. When the bidirectional lead screw 206 rotates, it causes the two support plates 202 to move closer together. The two support plates 202 then move the two support rods 204, which in turn move the two arc-shaped frames 205 closer together to clamp and fix the outer wall of the pipe fitting sheet metal. This prevents the pipe fitting sheet metal from moving during processing, improving processing quality. When the arc-shaped frames 205 clamp and fix the pipe fitting sheet metal, the outer wall of the pipe fitting sheet metal presses against the push plate 306. The push plate 306 moves the moving block 302 and presses the spring 305. When the moving block 302 moves the fixed rod 311, it slides in the adjusting groove 310, which in turn drives the adjusting rod 309 to rotate. The other end of the adjusting rod 309 drives the fixed block 313 and the arc plate 314 to move. The arc plate 314 presses and fixes the edges of both ends of the pipe sheet metal, so that when the pipe sheet metal is cut, it is not easy for axial movement to occur, resulting in deviation of the cutting position, ensuring the accuracy of cutting and improving the cutting quality.

[0046] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0047] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
