Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a laser cutting device for automobile exhaust pipes, the core structure of which is mainly composed of a base plate 1, a support frame 2 is provided on the base plate 1, and a laser cutting head 3 for laser cutting is installed on the support frame 2.

[0023] In the area from the left end to the right end of the base plate 1, a fixed seat 4, a low slide rail 5 and a high slide rail 6 are arranged in sequence. A drive motor 7 is installed on the fixed seat 4, and the output end of the drive motor 7 is connected to a threaded shaft 8.

[0024] A movable block 9 is screwed onto the threaded shaft 8. The movable block 9 is connected to the low slide rail 5 through the first slider 10. A movable support plate 11 is provided above the movable block 9. The movable support plate 11 is provided with a clamping groove 12 for fixing the workpiece. The clamping groove 12 is located directly below the laser cutting head 3.

[0025] Each of the four side walls of the clamping groove 12 is equipped with threaded clamping rods 13 for fixing the workpiece, while the bottom end of the clamping groove 12 is equipped with a second slider 14, which slides on the high slide rail 6 to facilitate the positioning and movement of the workpiece in the vertical direction. This design allows the laser cutting device to more accurately control the position of the workpiece during cutting operations, thereby improving the cutting accuracy and efficiency.

[0026] Specifically, in the structural design of the base plate 1, a bearing fixing seat 15 is specially set. This design allows the threaded shaft 8 to pass smoothly through and be fixed inside the preset bearing, ensuring the stability and load-bearing capacity of the shaft.

[0027] To elaborate further, the edge of the base plate 1 is carefully designed with multiple small supports 16. These supports 16 not only provide stable support for the entire structure, but also have a precision photoelectric sensor 17 mounted on top of each support 16. The function of these sensors 17 is to monitor the movement status of the first slider 10 on the low slide rail 5 in real time, ensuring its precise movement.

[0028] In this design, the number of low-profile guide rails 5 is determined to be two, and they are arranged in a front-to-back sequence. Correspondingly, the number of moving blocks 9 is also designed to be two, and both moving blocks 9 are firmly connected to the moving support plate 11. This design allows the two moving blocks 9 to work together to complete the predetermined moving task.

[0029] The clamping slot 12 features a specially designed strip-shaped opening 18 at its bottom. This design facilitates precise cutting operations by the laser cutting head 3. The strip-shaped opening 18 provides sufficient space and convenience for the cutting head, thereby improving the efficiency and accuracy of the entire processing.

[0030] Working principle: When this utility model is in operation, the base plate 1 serves as the basic support structure for the entire device, and the support frame 2 is installed on the base plate 1 to fix the laser cutting head 3.

[0031] The base plate 1 is provided with a fixed seat 4, a low slide rail 5, and a high slide rail 6 from left to right. A drive motor 7 is mounted on the fixed seat 4, and the drive end of the drive motor 7 is connected to a threaded shaft 8.

[0032] A movable block 9 is screwed onto the threaded shaft 8. The movable block 9 is connected to the low slide rail 5 through the first slider 10, so as to move along the low slide rail 5.

[0033] A movable support plate 11 is provided above the movable block 9. The movable support plate 11 is provided with a clamping groove 12. The clamping groove 12 is located below the laser cutting head 3 and is used to fix the car exhaust pipe to be cut.

[0034] The four side walls of the clamping groove 12 are provided with threaded clamping rods 13. By rotating the threaded clamping rods 13, the exhaust pipe in the clamping groove 12 can be clamped or released, thereby fixing and releasing the exhaust pipe.

[0035] The bottom end of the clamping groove 12 is provided with a second slider 14, which is slidably mounted on the high slide rail 6, so that the moving support plate 11 can move in the vertical direction to adapt to the cutting requirements of exhaust pipes at different heights.

[0036] The base plate 1 is provided with a bearing mounting seat 15, and the threaded shaft 8 passes through the bearing mounting seat 15 to ensure the stability of the threaded shaft 8 during rotation and reduce friction.

[0037] The edge of the base plate 1 is provided with multiple small brackets 16, and photoelectric sensors 17 are installed on the brackets 16 to monitor the position of the first slider 10 on the low slide rail 5, so as to ensure the accuracy of the cutting process.

[0038] There are two low slide rails 5, which are distributed in front and behind. There are also two corresponding moving blocks 9. Both moving blocks 9 are fixedly connected to the moving support plate 11, which ensures the stable movement of the moving support plate 11.

[0039] The bottom of the clamping groove 12 is provided with a strip opening 18, which facilitates the laser cutting head 3 to perform cutting operations and allows the exhaust gas generated during cutting to be discharged.

[0040] With the above structure, the laser cutting head 3 can move along the low slide rail 5 and the high slide rail 6 under the control of the drive motor 7 to perform precise laser cutting on the automobile exhaust pipe clamped in the clamping slot 12.
