[0023] like Figure 1 , Figure 2 and Figure 4 As shown, a muffler pipe cutting device of this embodiment includes a device body 1 and a workbench 2, a cutting device 7 and a pressing device 8 installed on the device body 1. The workbench 2 is arranged horizontally and fixedly installed on the device body 1. A placement seat 3 for placing the muffler pipe is installed on the workbench 2. The upper surface of the placement seat 3 in this embodiment is an arc-shaped surface that fits the outer surface of the muffler pipe to be processed. Lugs 31 are provided on both sides of the placement seat 3. The lugs 31 are penetrated by holes for screws to pass through. The workbench 2 is provided with threaded holes 24 corresponding to the positions of the above-mentioned holes, and a plurality of threaded holes 24 are arranged at intervals along the radial direction of the muffler pipe for adapting to the installation of placement seats 3 of different sizes (refer to Figure 1), when installing the placement seat 3, first place the placement seat 3 on the workbench 2, then pass one end of the fastening screw through the through hole on the lug 31 and then screw it into the corresponding threaded hole 24, so as to achieve the installation and fixation of the placement seat 3. When the size of the muffler to be processed changes and the placement seat 3 needs to be replaced, just loosen and remove the fastening screw, and the placement seat 3 can be removed and replaced with a placement seat 3 of matching size. When installing the new placement seat 3, repeat the above installation steps. In this embodiment, at least one slideway 22 is provided on the workbench 2 along the axial extension of the muffler to be processed, and the placement seat 3 is slidably matched with the above slideway 22.

With this structure, it is more convenient to initially limit the placement seat 3, prevent the placement seat 3 from being displaced in the horizontal direction, and is conducive to improving the installation reliability of the placement seat 3.
[0024] The clamping device 8 and the cutting device 7 are respectively located above the placement seat 3. Specifically, a bracket is fixedly provided on the equipment body 1, and the clamping device 8 and the cutting device 7 are both installed on the bracket. The cutting device 7 adopts the structure in the prior art, and this embodiment will not be repeated. In this embodiment, there are two clamping devices 8, which are respectively set on both sides of the cutting device 7, and are used to clamp and fix the two sides of the part to be cut on the muffler to ensure the smooth progress of the cutting work. The clamping device 8 includes a driving member 81 and a pressing plate 82. The driving member 81 adopts a cylinder, and the cylinder is fixedly installed on the bracket, and the telescopic end of the cylinder is connected to the pressing plate 82 by bolts. The bottom surface of the pressing plate 82 is an arc surface that fits the outer surface of the muffler to be processed. The pressing plate 82 is arranged relative to the placement seat 3. When the telescopic end of the cylinder is extended, it drives the pressing plate 82 to move in the direction close to the muffler until it is pressed against the outer surface of the muffler, and cooperates with the placement seat 3 to achieve the clamping and fixing of the muffler. When the size of the muffler pipe to be processed changes, the lower pressing plate 82 is removed and replaced with a pressing plate 82 of a matching size.
[0025] In order to facilitate confirmation of the cutting size and position of the muffler to be processed, this embodiment is provided with a retractable movable plate 4 on one side of the workbench 2, and one end of the movable plate 4 is slidably connected to the workbench 2. The sliding connection method adopts the structure in the prior art and is not repeated here. A baffle 42 is fixedly provided at the other end of the movable plate 4. The baffle 42 extends radially along the muffler and is used to limit the end face position of the muffler. After the movable plate 4 is moved, the baffle 42 is fixed to the position of the equipment body 1 through the limit seat 5. The limit seat 5 is installed on the equipment body 1 in an adjustable position. The limit seat 5 is connected to the baffle 42 through a connector 9, and the distance between the limit seat 5 and the baffle 42 is relatively adjustable. Specifically, the limit seat 5 includes a horizontal plate 51 and a vertical plate 52 that are fixed together, the vertical plate 52 is connected to the baffle 42 through a connecting member 9, the horizontal plate 51 is connected and fixed to the device body 1 through a fastening bolt, and the device body 1 is provided with a plurality of adjustment holes 11 at intervals along the moving direction of the moving plate 4, and the plurality of adjustment holes 11 correspond to the installation positions of the horizontal plate 51. The connecting member 9 is a locking bolt, one end of which passes through the vertical plate 52 and the baffle 42 and is fastened by a nut, the axis of the locking bolt is parallel to the axis of the muffler, and both are arranged in the horizontal direction, and a nut is threadedly connected to the outer side of the locking bolt at a position between the vertical plate 52 and the baffle 42, and the baffle 42 is clamped and fixed between the two nuts. When the moving plate 4 is moved, the limit seat 5 is moved to a suitable position along the moving direction of the moving plate 4, and then one end of the fastening bolt is passed through the horizontal plate 51 and the adjustment hole 11 at the corresponding position on the device body 1 in sequence, and then fastened by a nut, so that the limit seat 5 is fixedly installed on the device body 1. Then one end of the connecting member 9 is passed through the vertical plate 52 and the baffle 42 in sequence, and then fastened by a nut. Since the position of the baffle 42 on the connecting member 9 is limited by clamping two nuts, when the position of the baffle 42 needs to be fine-tuned, it is only necessary to loosen the nuts on both sides of the baffle 42 to adjust the horizontal position of the baffle 42. After adjustment, tighten the two nuts to fix the position of the baffle 42.
[0026] In addition, a measuring assembly 6 is also installed on the workbench 2 of this embodiment, and the measuring assembly 6 includes a rotatably mounted rotating shaft 61 and a measuring ruler 62 with one end wound around the outside of the rotating shaft 61, and the other end of the measuring ruler 62 is fixedly connected to the moving plate 4.

An observation window 21 for checking the value of the measuring ruler 62 is opened on the workbench 2 of this embodiment at the position corresponding to the cutting point of the cutting device 7.
[0027] During the cutting operation, first place the silencer pipe to be processed on the placement seat 3, with one end against the baffle 42, then move the silencer pipe to drive the movable plate 4 and the baffle 42 to move together, and at the same time check the value displayed on the measuring ruler 62 through the observation window 21. When the value of the measuring ruler 62 displayed in the observation window 21 meets the processing requirements, stop moving, and fix the position of the baffle 42 through the limit seat 5, then the cylinder of the clamping device 8 can be controlled to start, and the pressure plate 81 can be controlled to move down until the silencer pipe is pressed and fixed between the placement seat 3 and the pressure plate 81; then the cutting device 7 is started, and the cutting operation can be carried out.
[0028] Since chips are generated during the cutting operation, in order to collect the chips in a centralized manner, a mounting groove 23 is provided on the workbench 2 at a position directly opposite the cutting device 7, and a chip collecting box is detachably installed in the mounting groove 23. The specific structure of the chip collecting box in this embodiment is a box-shaped structure with an opening at the upper end, and the upper end opening is bent outward to form a flange.
