Abstract
Description
Technical Field
[0001] This utility model relates to the field of elbow pipe technology, specifically to a laser cutting device for elbow pipes. Background Technology
[0002] An elbow is a pipe fitting that changes the direction of a pipeline. It is typically made of metal or high-performance plastic and has a specific bending angle and radius. In the intake and exhaust systems of an automotive engine, elbows precisely guide airflow, optimize gas flow paths, improve engine intake efficiency and exhaust smoothness, thereby enhancing power performance and reducing emissions. Simultaneously, in automotive fuel delivery and cooling systems, elbows also function to connect different components and optimize pipeline layout, ensuring the stable and reliable operation of each system.
[0003] After the elbow pipe is shaped, both ends need to be cut to meet the qualified diameter standard. However, it is not convenient to fix elbow pipes with different internal diameters on a separate cutting table. Also, after fixing, it is not convenient to adjust the position where cutting is required. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a laser cutting device for elbow pipes, including a cutting table, a mounting platform fixedly connected to the top of the cutting table, a mounting plate one fixedly connected to the right end of the mounting platform, a servo motor mounted on the top of the mounting plate one, a lead screw fixedly connected to the output end of the servo motor, a moving platform threadedly connected to the surface of the lead screw, a connecting platform fixedly connected to the bottom of the moving platform, an electric hydraulic rod mounted on the front of the connecting platform, a cutting head mounted on the output end of the electric hydraulic rod, a second mounting plate fixedly connected to the top of the cutting table, an electric telescopic rod fixedly connected to the front of the second mounting plate, a movable arc plate fixedly connected to the output end of the cutting table, a connecting block fixedly connected to the bottom of the movable arc plate, a slider fixedly connected to the surface of the connecting block, a spring fixedly connected to the rear end of the connecting block, a sliding groove opened inside the cutting table, and a fixed platform fixedly connected to the top of the cutting table.
[0005] The above technical solution involves setting up a movable arc plate and a fixed platform, activating an electric telescopic rod, and using the electric telescopic rod to extend the movable arc plate to the rear end, placing the elbow pipe to be processed between the movable arc plate and the fixed platform. Subsequently, the output end of the electric telescopic rod drives the movable arc plate to move towards one end closer to the surface of the elbow pipe until the pipe is fixed. The distance between the movable arc plate and the fixed platform can be adjusted to facilitate the fixing of elbow pipes with different inner diameters.
[0006] As a further improvement to the above solution, the left end of the lead screw penetrates the inner wall of the mounting platform.
[0007] With the above technical solution, the left end of the lead screw penetrates the inner wall of the mounting platform. This design can ensure the stability of the lead screw during rotation and prevent the lead screw from deviating during operation. This ensures that the moving platform connected to the lead screw by the thread can move linearly according to the rotation of the lead screw, thereby improving the accuracy of the cutting operation of the entire device.
[0008] As a further improvement to the above solution, the cutting head is located above the fixed platform.
[0009] As a further improvement to the above solution, two sliders are provided, and the two sliders are evenly distributed on the left and right ends with the center of the front of the connecting block symmetrically.
[0010] With the above technical solution, two sliders are set and symmetrically distributed at both ends of the connecting block's front center. This symmetrical distribution allows the connecting block to maintain balance when moving or under force. During the movement of the curved plate, the two sliders work together to slide more stably within the groove, ensuring the smoothness of the curved plate's movement and thus ensuring the stability of the fixing or adjustment operation of the elbow pipe.
[0011] As a further improvement to the above solution, the slider is slidably connected inside the groove.
[0012] With the above technical solution, the slider is slidably connected inside the groove. This connection method provides guidance for the movement of the movable arc plate, so that the movable arc plate can only move in the direction of the groove, thereby precisely controlling the movement trajectory of the movable arc plate, and thus ensuring that the fixing or adjustment operations of the elbow pipe related to the movable arc plate can be carried out accurately.
[0013] As a further improvement to the above solution, a support platform is fixedly connected to the bottom of the cutting table, a cabinet door is hinged to the front of the support platform, and a support pad is fixedly connected to the bottom of the support platform.
[0014] Through the above technical solution, the support platform at the bottom of the cutting table provides additional support for the entire cutting device, increasing its stability. The cabinet door is hinged to the front of the support platform, facilitating access to its interior, such as for storing tools or parts related to the cutting device. Support pads are located at the bottom of the support platform, serving two purposes: firstly, to cushion the impact of vibrations generated during operation on the ground or placement surface; and secondly, to increase the friction between the support platform and the placement surface, further enhancing the device's stability.
[0015] As a further improvement to the above solution, the number of cabinet doors is set to four, and the four cabinet doors are evenly distributed on the surface with respect to the center of the front of the support platform.
[0016] As a further improvement to the above solution, the number of support pads is set to four, and the four support pads are evenly distributed on the surface with respect to the center of the bottom of the cutting table.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This invention involves setting up a movable arc plate and a fixed platform. Activating an electric telescopic rod causes the movable arc plate to extend and retract towards the rear, placing the elbow pipe to be processed between the movable arc plate and the fixed platform. Subsequently, the output end of the electric telescopic rod moves the movable arc plate closer to the surface of the elbow pipe until the pipe is fixed. The distance between the movable arc plate and the fixed platform can be adjusted to facilitate the fixing of elbow pipes with different inner diameters.
[0019] This invention features a movable stage, a servo motor, and a lead screw driven by the output of the servo motor. The rotation of the lead screw causes the movable stage to move on the surface of the lead screw, allowing it to be adjusted to a suitable position for cutting. Attached Figure Description

[0029] When in use, the electric telescopic rod 11 is activated, which drives the movable arc plate 12 to extend and retract to the rear end, placing the elbow pipe to be processed between the movable arc plate 12 and the fixed platform 17. Then, the output end of the electric telescopic rod 11 drives the movable arc plate 12 to move towards one end of the elbow pipe surface until the pipe is fixed.
