Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and more specifically, to a fixing device for cutting parts. Background Technology

[0002] In the production of new energy vehicles, rectangular-mouthed bent tube parts are used in the structural design of battery packs, vehicle power systems, and body structures. During the processing of these parts, laser cutting machines are used to cut long holes and round holes on the surface of the parts.

[0003] Existing fixing devices consist of parallel clamps that apply pressure to both ends of the part to fix it in place. However, laser cutting generates a lot of heat, and the combined effect of applying opposing pressure to the part causes stress to concentrate in the bent section, which can easily lead to deformation of the part and affect the processing quality. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a fixing device for cutting parts, which solves the problem that laser cutting generates a lot of heat and, combined with applying opposing pressure to the parts, causes stress to concentrate in the bent part, which can easily lead to deformation of the parts and affect the processing quality of the parts.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing device for cutting parts, including a worktable, a three-axis moving frame is provided on the worktable, a laser cutter is provided on the three-axis moving frame, a fixed base is also fixedly installed on the worktable, a tray is symmetrically arranged above the fixed base, symmetrical vertical plates are fixedly installed on the tray, hydraulic telescopic rods are fixedly installed on the opposite sides of the vertical plates, the telescopic end of the hydraulic telescopic rod is fixedly connected to a fixing plate for fixing both ends of the bent pipe part, a rotating shaft is also fixedly fixed on the tray, a gear one is fixedly installed in the middle of the rotating shaft, an adjusting frame is rotatably connected to the rotating shaft, a drive motor one is fixedly installed on the adjusting frame, a gear two is fixedly connected to the output end of the drive motor one, and the gear one and gear two mesh with each other;

[0006] The workbench is equipped with a flipping assembly for flipping and turning tube parts, and a distance adjustment assembly for adjusting the distance between the two trays is also provided on the workbench.

[0007] Preferably, the two fixing plates on the same tray are parallel to each other, and the tray has a circular structure.

[0008] Preferably, the flipping assembly includes two drive frames, which are symmetrically fixedly mounted on a fixed base. A second drive motor is fixedly mounted on the top of each drive frame, and a third gear is fixedly connected to the output end of the second drive motor. A horizontal toothed roller is fixedly connected to the adjusting frame, and the third gear meshes with the toothed roller.

[0009] Preferably, the adjusting assembly includes two toothed plates, which are symmetrically arranged on a fixed base and can slide horizontally on the fixed base. Each toothed plate is fixedly mounted with a support frame, the top of which is rotatably connected to the toothed roller. A drive motor is fixedly mounted inside the fixed base, and a gear is fixedly connected to the output end of the drive motor, which meshes with the toothed plate.

[0010] Preferably, the toothed roller has a toothed length greater than that of the gear three.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention drives a motor to rotate a gear, which in turn rotates a transmission tray to an angle that matches the angle of the bent pipe part. Then, by extending a hydraulic telescopic rod, two fixing plates can clamp and fix the end of the bent pipe part, thereby reducing the stress on the middle of the bent pipe part, preventing deformation of the bent pipe part, and avoiding affecting the processing quality of the part.

[0013] This invention drives a second motor to drive a third gear to rotate, which in turn drives the gear three to mesh and rotate the toothed roller. This causes the bent pipe part held by the fixed plate to rotate at a certain angle along with the adjusting frame, so that the laser cutter can cut multiple sides of the bent pipe part without having to disassemble and fix it again, thus improving the cutting efficiency.

[0014] This invention uses a three-drive motor to drive a four-drive gear to rotate. The four-drive gear then meshes with a toothed plate that slides horizontally along a fixed base. The distance between the two trays can be adjusted according to the length of the bent pipe parts at different ends, thereby improving the overall applicability of the device.

[0025] The three-axis moving frame 2 can move in the xyz three-axis directions, which is existing technology.

[0026] Specifically, the drive motor 13 drives the gear 14 to rotate, causing the gear 14 to mesh with the gear 11 and rotate the transmission tray 6 to an angle that matches the bent pipe part 4. Then, the hydraulic telescopic rod 8 extends, allowing the two fixing plates 9 to clamp and fix the end of the bent pipe part 4, thereby reducing the force on the middle of the bent pipe part 4 and preventing deformation of the bent pipe part 4.

[0027] Preferably, the two fixing plates 9 on the same tray 6 are parallel to each other, and the tray 6 has a circular structure.

[0028] Preferably, the flipping assembly 15 includes two drive frames 151, which are symmetrically fixedly mounted on the fixed base 5. A second drive motor 152 is fixedly mounted on the top of the drive frame 151. A third gear 153 is fixedly connected to the output end of the second drive motor 152. A horizontal toothed roller 154 is fixedly connected to the adjusting frame 12. The third gear 153 and the toothed roller 154 mesh with each other.

[0029] Specifically, by driving the gear 153 to rotate via the second drive motor 152, the gear 153 can mesh with the transmission roller 154 to rotate, thereby causing the bent pipe part 4 held by the fixed plate 9 to rotate 90° with the adjusting frame 12, so that the laser cutter 3 can cut multiple sides of the bent pipe part 4 without having to disassemble and fix the bent pipe part 4 again.

[0030] Preferably, the pitch adjustment assembly 16 includes two toothed plates 161, which are symmetrically arranged on the fixed base 5 and can slide horizontally on the fixed base 5. Each toothed plate 161 is fixedly mounted with a support frame 162, the top of which is rotatably connected to the toothed roller 154. A drive motor 163 is fixedly mounted inside the fixed base 5, and a gear 164 is fixedly connected to the output end of the drive motor 163. The gear 164 meshes with the toothed plate 161.

[0032] Preferably, the toothed roller 154 has a toothed length greater than that of the gear 153, so that the gear 153 and the toothed roller 154 remain engaged during the adjustment of the pitch adjustment assembly 16.

[0033] The working process of this utility model is as follows:

[0034] In use, the drive motor 13 drives the gear 2 14 to rotate, causing the gear 2 14 to mesh with the gear 11 and rotate the transmission tray 6 to an angle that matches the bent pipe part 4. At the same time, the drive motor 3 163 drives the gear 4 164 to rotate, and the gear 4 164 then meshes with the toothed plate 161 to slide horizontally along the fixed base 5. The distance between the ends of the bent pipe part 4 is adjusted by adjusting the distance between the two trays 6. Then, the bent pipe part 4 is placed on the tray 6. Then, the hydraulic telescopic rod 8 is extended, which allows the two fixed plates 9 to clamp and fix the ends of the bent pipe part 4. Then, the three-axis moving frame 2 drives the laser cutter 3 to cut the bent pipe part 4. Then, the drive motor 2 152 drives the gear 3 153 to rotate, causing the bent pipe part 4 clamped by the fixed plate 9 to rotate 90° with the adjusting frame 12, cutting multiple sides of the bent pipe part 4.
