Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe cutting devices, and in particular to a positioning and cutting device for connecting steel pipes in electric vehicles. Background Technology

[0002] With the popularization of green travel concepts and the rapid development of the new energy vehicle industry, electric vehicles have become an important part of the transportation sector. As one of the core structural components of electric vehicles, the manufacturing precision and safety of the frame are directly related to the overall vehicle performance and service life. Among them, the connecting steel tube, as a key support component of the frame, has its processing quality directly affecting the strength, rigidity and assembly precision of the frame.

[0003] When steel pipe cutting devices are in use, traditional steel pipe cutting devices mostly adopt manual chuck positioning or simple mechanical limit structures. The cutting size adjustment depends on manual calibration, which has problems such as large fluctuations in positioning accuracy and complex operation. Especially in mass production scenarios, the frequent need for size adjustment leads to a longer production cycle, and manual intervention is prone to introducing error accumulation. In addition, conventional unloading methods mostly use free fall or simple inclined guide plates. When steel pipes collide with hard structures, they are prone to surface damage such as dents and scratches, resulting in an increased defect rate. In mass production, traditional cutting equipment leads to an increased material waste rate due to positioning errors, and the rework cost caused by unloading damage is high. These problems are particularly prominent in the processing of high-precision pipe components such as electric vehicle frames and steering brackets, becoming key bottlenecks restricting production efficiency and product quality.

[0004] Therefore, to address the issues of low positioning accuracy and high unloading damage rate in mass production of steel pipes, a positioning and cutting device for connecting steel pipes in electric vehicles can be designed. When in use, the entire process utilizes a gear and rack mechanism to achieve millimeter-level cutting size adjustment, hydraulic drive to ensure cutting plane stability, and a rotating unloading mechanism to prevent deformation damage caused by the free fall of steel pipes in traditional equipment. Simultaneously, the reciprocating motion design ensures the continuity of batch cutting. Through mechatronics innovation, this device solves the defects of low positioning accuracy, high unloading damage rate, and low mass production efficiency in steel pipe cutting, providing a high-precision, high-reliability, and low-cost pipe processing solution for the electric vehicle manufacturing industry. Utility Model Content

[0005] To overcome the challenges of frequent size adjustments in mass production scenarios when using steel pipe cutting equipment, which leads to extended production cycles and the accumulation of errors due to manual intervention, and the fact that conventional unloading methods often employ free fall or simple inclined guide plates, which can easily cause dents, scratches, and other surface damage when steel pipes collide with rigid structures, resulting in a higher defect rate, it is difficult to simultaneously solve the problems of low positioning accuracy and high unloading damage rate in steel pipe cutting.

After the steel pipe is cut, the drive... The fixed arc frame rotates, and the cut steel pipes automatically roll into the product collection frame under gravity. Then the device rotates in the opposite direction to reset and start the next cycle. The entire process achieves millimeter-level cutting size adjustment through a gear and rack mechanism, and hydraulic drive ensures the stability of the cutting plane. The rotating unloading mechanism avoids deformation damage caused by the free fall of steel pipes in traditional equipment. At the same time, the reciprocating motion design ensures the continuity of batch cutting. Through mechatronics innovation, this device solves the defects of low positioning accuracy, high unloading damage rate, and low batch production efficiency in steel pipe cutting, providing a high-precision, high-reliability, and low-cost pipe processing solution for the electric vehicle manufacturing industry.

Since the adjusting gear meshes with the adjusting toothed plate, the rotation of the adjusting gear causes the adjusting toothed plate to slide smoothly outwards. At this time, the adjusting toothed plate can then drive the movable positioning frame to slide smoothly outwards, adjusting the distance between the movable positioning frame and the fixed arc-shaped frame, forming a variable cutting size positioning structure. Subsequently, the end of the steel pipe is precisely abutted against the inner wall of the positioning frame after loading. At this point, the laser cutting equipment starts and completes a single cut. After the steel pipe is cut, the fixed... The curved frame rotates, and the cut steel pipes automatically roll into the product collection frame under gravity. Then, the device rotates in the opposite direction to reset and start the next cycle. The entire process achieves millimeter-level cutting size adjustment through a gear and rack mechanism, and hydraulic drive ensures the stability of the cutting plane. The rotating unloading mechanism avoids deformation damage caused by the free fall of steel pipes in traditional equipment.

[0026] Please see Figure 1 and Figure 4The adjustment assembly also includes a mounting slot 17, a drive motor 18, a drive shaft 19, a drive gear 20, and a driven half gear 21. The mounting slot 17 is provided through the interior of the fixed base 2. The drive motor 18 is fixedly installed inside the mounting slot 17.

Activating the hydraulic cylinder 26 can push the fixed seat 2 to move smoothly inward.

[0027] When the steel pipe cutting device is in use, when positioning the steel pipe cutting position, firstly, starting the adjusting motor 7 will drive the adjusting gear 9 to rotate through the adjusting shaft 8.

[0028] Subsequently, starting the hydraulic cylinder 26 can push the fixed seat 2 to move smoothly inward. The fixed seat 2 can then drive the slide 24 to move smoothly along the slide rod 23, so that the end of the steel pipe after loading accurately abuts against the inner wall of the positioning frame. At this time, the laser cutting equipment 1 starts to complete a single cut. After the steel pipe is cut, starting the active motor 18 can drive the active gear 20 to rotate through the active shaft 19.

Then the device rotates in the opposite direction to reset and start the next cycle.

[0029] The entire process achieves millimeter-level cutting size adjustment through a gear and rack mechanism, hydraulic drive ensures the stability of the cutting plane, and a rotary unloading mechanism avoids deformation damage caused by the free fall of steel pipes in traditional equipment. At the same time, the reciprocating motion design ensures the continuity of batch cutting. Through mechatronics innovation, this device solves the defects of low positioning accuracy, high unloading damage rate, and low batch production efficiency in steel pipe cutting, providing a high-precision, high-reliability, and low-cost pipe processing solution for the electric vehicle manufacturing industry.

Since the adjusting gear 9 meshes with the adjusting toothed plate 6, the rotation of the adjusting gear 9 can drive the adjusting toothed plate 6 to slide smoothly outward. At this time, the adjusting toothed plate 6 can drive the movable positioning frame 4 to slide smoothly outward, and the distance between the movable positioning frame 4 and the fixed arc frame 3 will be adjusted accordingly, forming a variable cutting size positioning structure.
