Description

Technical Field

[0001] This utility model relates to the field of laser processing auxiliary tool technology, specifically a laser processing auxiliary fixture. Background Technology

[0002] Among existing technologies, SUS material forming requires a material thickness of 0.03mm-1.0mm. Considering cost and effectiveness, laser processing is currently the best processing method among various processing techniques available on the market.

[0003] In the laser cutting process, in order to ensure the cutting quality, it is usually necessary to adopt the suspended cutting method and use auxiliary gas to optimize the cutting effect and reduce burr generation. However, in actual operation, suspended cutting and auxiliary air blowing should be used. When cutting to the same edge of the workpiece, the workpiece is prone to slight deformation due to the combined effect of the material's own weight and the blowing force of the auxiliary gas, which eventually leads to step-like defects on the cutting edge. At the same time, the cutting efficiency, cutting accuracy and cutting yield are very low.

[0004] Therefore, there is an urgent need for a laser processing auxiliary fixture to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a laser processing auxiliary fixture to solve the problems mentioned in the background art.

A pressure-drawing assembly, installed on the carrier box, is used to assist in the pressure-drawing process inside the carrier box; And, a pressure roller assembly installed on the carrier box to assist in clamping and flattening the placed material.

[0007] The support assembly includes a mounting groove at the upper end of the support box, on which a support plate for placing materials is placed, and multiple sets of through holes are formed on the support plate.

[0008] Two sets of the pressure roller assembly are symmetrically arranged on the bearing box.

[0009] The pressure roller assembly includes a mounting frame fixed to a carrier box, a U-shaped frame connected to the mounting frame via an elastic component, a pressure roller mounted on the U-shaped frame for pressing against the material placed on the carrier plate, and a rotating component mounted on the U-shaped frame for rotating the pressure roller.

[0010] The rotating assembly includes a mounting shaft rotatably connected to a U-shaped frame, the pressure roller is fixed to the mounting shaft, and a drive motor for driving the mounting shaft is mounted on the U-shaped frame.

One end of the sliding rod is fixed to the U-shaped frame. A spring is sleeved on the outside of the sleeve. The two ends of the spring are respectively connected to the mounting frame and the U-shaped frame.

[0012] The pressure extraction assembly includes a blower installed on one side of the carrier box. The blower is provided with an air inlet and an air outlet. The air inlet is connected to the interior of the carrier box by a corrugated pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a laser processing auxiliary fixture. During the laser cutting process of SUS material forming, the load-bearing component, the suction component, and the pressure roller component work together to flatten, limit, and adsorb the SUS material.

[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] Please see Figure 1-4 The present invention provides a laser processing auxiliary fixture, including a carrier box 1, and further comprising: A load-bearing component, mounted on the load-bearing box 1, is used to assist in supporting the processing materials. A pressure-drawing assembly, disposed on the carrier box 1, is used to assist in the internal pressure-drawing of the carrier box 1; And, a pressure roller assembly installed on the carrier box 1 to assist in clamping and flattening the placed material; It should be noted that during the laser cutting process for SUS material, the SUS material is flattened, limited, and adsorbed through the cooperation of the load-bearing component, the pressure component, and the pressure roller component. Through adsorption and elastic limiting, deformation of the SUS material is avoided during subsequent cutting, ensuring cutting efficiency, cutting accuracy, and cutting yield.

[0018] The support assembly includes a mounting groove 201 opened at the upper end of the support box 1, a support plate 202 for placing materials is placed on the mounting groove 201, and multiple sets of through holes 203 are opened on the support plate 202. It should be noted here that the support plate 202 placed on the mounting groove 201 facilitates the support of materials.

[0019] Two sets of pressure roller assemblies are symmetrically arranged on the bearing box 1; It should be noted here that the extrusion limiting effect is ensured by using two sets of symmetrically arranged pressure roller assemblies.

[0020] The pressure roller assembly includes a mounting frame 401 fixed on the bearing box 1, a U-shaped frame 402 connected to the mounting frame 401 by an elastic component, a pressure roller 403 for pressing against the material placed on the bearing plate 202, and a rotating component for rotating the pressure roller 403. It should be noted that during the laser cutting process of SUS material forming, the SUS material is supported and limited by a fixture. During the support and limiting process, the U-shaped frame 402 is pulled away from the support plate 202, creating a gap between the pressure roller 403 on the U-shaped frame 402 and the support plate 202. At this time, the SUS material to be processed is placed flat on the support plate 202. After the SUS material is placed, the pulling of the U-shaped frame 402 is released. Through the elastic force of the elastic component, the U-shaped frame 402 is pushed to reset and the pressure roller 403 is pressed against the placed SUS material. After pressing against each other, the placed SUS material is supported and limited.

[0021] The rotating assembly includes a mounting shaft 501 rotatably connected to a U-shaped frame 402, a pressure roller 403 fixed to the mounting shaft 501, and a drive motor 502 for driving the mounting shaft 501 mounted on the U-shaped frame 402. It should be noted that the driving action of the drive motor 502 and the connecting action of the mounting shaft 501 facilitate the rotation of the pressure roller 403.

[0022] The elastic component includes multiple sets of sleeves 601 fixed on the mounting bracket 401. A slide rod 602 is slidably connected to the sleeve 601. One end of the slide rod 602 is fixed to the U-shaped bracket 402. A spring 603 is sleeved on the outside of the sleeve 601. The two ends of the spring 603 are respectively connected to the mounting bracket 401 and the U-shaped bracket 402. It should be noted that the sleeve 601 and the slide rod 602 facilitate the telescopic connection between the auxiliary mounting bracket 401 and the U-shaped bracket 402, and the spring 603 facilitates the reset of the U-shaped bracket 402 after telescopic movement.

[0023] The pressure extraction assembly includes a blower 301 installed on one side of the carrier box 1. The blower 301 is provided with an air inlet and an air outlet. A corrugated pipe 302 is connected between the air inlet and the interior of the carrier box 1. It should be noted here that the internal pressure of the bearing box 1 is extracted by the driving action of the exhaust fan 301 and the connecting action of the bellows 302.

[0024] Working principle: During the process of forming and processing SUS material using laser cutting, the SUS material is supported and limited by a fixture. During the support and limiting process, the U-shaped frame 402 is pulled away from the support plate 202, so that the pressure roller 403 on the U-shaped frame 402 and the support plate 202 are separated. At this time, the SUS material to be processed is placed flat on the support plate 202. After the SUS material is placed, the pull on the U-shaped frame 402 is released. Through the elastic force of the elastic component, the U-shaped frame 402 is pushed to reset and the pressure roller 403 is pressed against the placed SUS material. After pressing against each other, the placed SUS material is supported and limited. After being supported and limited, the installation shaft 501 and the pressure roller 403 are driven to rotate by the drive motor 502, so that the two sets of pressure rollers 403 rotate in opposite directions. Since the two sets of pressure rollers 403 are pressed against the SUS material, the rotation of the two sets of pressure rollers 403 pulls the placed and limited SUS material to both sides to flatten it, which is convenient for subsequent higher quality laser cutting. After the SUS material is flattened and positioned, the interior of the carrier box 1 is compressed by the suction action of the exhaust fan 301 and the connection action of the corrugated pipe 302. During the compression process, the flattened and positioned SUS material is adsorbed through the through holes 203 on the carrier plate 202. Through adsorption and elastic positioning, the deformation of the SUS material is prevented during subsequent cutting, thus ensuring cutting efficiency, cutting accuracy and cutting yield.
