Specific embodiments

[0033] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0034] As Figures 1 - 5 collectively shown, the present utility model provides a cutting mechanism for processing automobile exhaust pipes that is convenient for positioning, including a base 1. Above the base 1, a conveying assembly 2, a supporting assembly 3, and a positioning assembly 4 are sequentially installed horizontally. Above the side of the supporting assembly 3 close to the positioning assembly 4, a cutting assembly 5 is fixedly arranged.

[0035] The conveying assembly 2 includes a plurality of conveying rollers 21. The conveying rollers 21 are driven by a motor to rotate. Both ends of the conveying rollers 21 are rotatably supported by bearing seats 22 respectively. A plurality of conveying wheels 23 arranged at equal intervals are fixedly installed on the conveying rollers 21. The conveying wheels 23 are provided with V-shaped grooves for receiving the pipe body 6. The conveying assembly 2 can realize the synchronous conveying of a plurality of pipe bodies 6.

[0036] The supporting assembly 3 includes a plurality of ring bodies 31. The ring bodies 31 are sleeved on the pipe body 6 to be cut. The ring bodies 31 are fixedly connected above the base 1. Four uniformly distributed support arms 32 are installed on the side of the ring bodies 31. Pressing wheels 33 are installed inside the support arms 32 for pressing the outer pipe wall of the pipe body 6 to ensure the stability of the pipe body 6 during the cutting process.

[0037] The positioning component 4 includes a positioning plate 41 arranged in the vertical direction. The bottom of the positioning plate 41 is connected to a linear slide rail 43 through a slider 42, and the linear slide rail 43 is fixedly connected to the base 1.

The adjusting screw 45 is threadedly connected in a fixed seat 44, and the fixed seat 44 is fixedly connected to the base 1. A handwheel 46 is installed at one end of the adjusting screw 45 away from the positioning plate 41.

[0038] An infrared rangefinder 47 is installed at the top of the positioning plate 41. The infrared rangefinder 47 is used to measure the distance between the laser cutting head 51 and the positioning plate 41. The distance between the laser cutting head 51 and the positioning plate 41 is the cutting length of the pipe body 6.

[0039] By rotating the adjusting screw 45 through the handwheel 46, the positioning plate 41 slides along the linear slide rail 43. The infrared rangefinder 47 measures the distance between the laser cutting head 51 and the positioning plate 41 in real time, that is, the cutting length of the pipe body 6 is determined.

[0041] The specific working principle of the present utility model:

[0042] Through the conveying component 2, the synchronous conveying of multiple pipe bodies 6 is realized. After passing through the supporting component 3, the pipe bodies 6 abut against the side of the positioning plate 41 of the positioning component 4. The laser cutting head 51 realizes the cutting of multiple pipe bodies 6 during the lateral movement, significantly improving the cutting efficiency.

[0043] The cutting length of the pipe body 6 can be flexibly positioned. By rotating the adjusting screw 45 through the handwheel 46, the positioning plate 41 slides along the linear slide rail 43. The infrared rangefinder 47 at the top of the positioning plate 41 can measure the distance between the laser cutting head 51 and the positioning plate 41 in real time, that is, the cutting length of the pipe body 6 is determined. The cutting length value is obtained through the reading of the infrared rangefinder 47, realizing the precise adjustment of the cutting length.
