They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "set up / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] Reference Figures 1-6 A laser cutting machine for processing treadmill parts includes a housing 1. A laser cutting mechanism 2 is fixedly installed inside the housing 1. The laser cutting mechanism 2 typically includes a laser head and a drive device for controlling the displacement of the laser head in the front-back, left-right, up-down directions. This is a mature existing technology and will not be described in detail here.

[0028] Two sets of clamping mechanisms 3 are arranged at the front and rear of the laser cutting mechanism 2. The clamping mechanism 3 includes a support plate 31 fixedly connected to the inner wall of the housing 1. A fixed block 32 is fixedly connected to the support plate 31. Several movable blocks 33 are equidistantly arranged on one side of the fixed block 32. In this embodiment, there are 6 movable blocks 33. Several movable blocks 33 are slidably connected to the support plate 31. Two first connecting rods 34 are coaxially hinged on the fixed block 32. Two second connecting rods 35 are coaxially hinged on the outermost movable block 33. Several X-shaped scissor connecting units 36 are arranged between the first connecting rods 34 and the second connecting rods 35. A driving mechanism 37 is fixedly installed on the support plate 31. The output end of the driving mechanism 37 is connected to one of the movable blocks 33.

[0029] The tops of the fixed block 32 and several movable blocks 33 are all fixed with clamping blocks 38. Each of the two adjacent clamping blocks 38 has a clamping groove 381 on its opposite side. It can be understood that the shape of the clamping groove 381 should match the shape of the pipe. For example, when the pipe is square, the clamping groove 381 is set to a corresponding square structure. When the pipe is round, the clamping groove 381 is set to a corresponding arc-shaped structure to ensure a good clamping effect.

[0030] A perforated mesh plate 4 is provided below the clamping mechanism 3. The perforated mesh plate 4 is fixedly connected to the inner wall of the box 1. A wind cover 5 is fixedly provided at the bottom of the box 1. A negative pressure fan 6 is connected to the wind cover 5 through a pipe. Box doors 7 are hinged to the front and rear sides of the box 1. An opening 8 for pipes to enter and exit is provided on the box door 7.

[0031] Additionally, the X-type scissor connection unit 36 ​​includes two support rods hinged together at the center. The support rods of two adjacent scissor units are hinged to each other. The support rod of the X-type scissor connection unit 36 ​​on one side edge is hinged to the first link 34, and the support rod of the X-type scissor connection unit 36 ​​on the other side edge is hinged to the second link 35.

[0032] When one of the movable blocks 33 moves, the X-shaped scissor unit composed of multiple hinged supports deforms, thereby driving the other movable blocks 33 to move synchronously. The structure is compact and stable, and can realize the synchronous movement of multiple movable blocks 33.

[0033] The drive mechanism 37 includes a motor fixedly mounted on a support plate 31. A drive wheel 371 is fixedly mounted on the output shaft of the motor. A support plate 31 is also fixedly mounted on the support plate 31. A driven wheel 372 is rotatably connected to the support. A transmission belt 373 is sleeved between the drive wheel 371 and the driven wheel 372. A connecting block 374 is fixedly mounted on a movable block 33. The connecting block 374 is fixedly connected to the transmission belt 373. In this embodiment, the connecting block 374 is located on the movable block 33, which is the third movable block 33 from the fixed block 32, that is, at the position where the driving force can act on the center of the movable block 33.

[0034] When the motor starts, the driving wheel 371, the driven wheel 372 and the transmission belt 373 work together, and the movable block 33 moves back and forth with the transmission belt 373 through the connecting block 374, thus realizing precise control of the movable block 33.

[0035] One of the movable blocks 33 is fixedly provided with a mounting block 9. A limiting rod 10 is fixedly provided on the side of the mounting block 9 facing the fixed block 32. A limiting block 11 for abutting the limiting rod 10 is fixedly provided on the support plate 31. In this embodiment, the mounting block 9 is provided on the movable block 33 closest to the fixed block 32. When the movable block 33 moves to the position of clamping the pipe fitting, the limiting rod 10 will abut against the limiting block 11, thereby restricting the further movement of the movable block 33 and limiting the sliding range of the movable block 33, thus avoiding excessive movement of the movable block 33.

[0036] A slide rail 12 is fixedly provided on the support plate 31, and a slide groove is provided at the bottom of the movable block 33 to slide in a straight line with the slide rail 12. Through the cooperation of the slide rail 12 and the slide groove, the movable block 33 can slide smoothly and stably in a straight line along the slide rail 12 when it is driven.

[0037] Rubber pads 13 are adhered to the inner walls of several clamping grooves 381. The rubber pads 13 have a certain elasticity and friction, which can better clamp the pipe and prevent it from sliding.

[0038] The door 7 has a through groove, and a transparent window 14 is embedded in the through groove, so that the staff can observe the cutting situation inside the box 1 without opening the door 7.

[0039] Working principle: When using this laser cutting machine, the multiple tubes to be cut are first pushed in through the opening 8 of the front door 7 of the housing 1, so that the tubes are located in the clamping groove 381 between the two clamping blocks 38. The drive mechanism 37 is started, which pushes one of the movable blocks 33 to slide along the support plate 31. Under the action of the X-type scissor connection unit 36, when one of the movable blocks 33 moves, the other movable blocks 33 move synchronously towards the fixed block 32 under the linkage of the X-type scissor connection unit 36, thereby driving the multiple clamping blocks 38 to clamp the tubes. The laser cutting mechanism 2 is then started to cut the tubes.

[0040] During the cutting process, metal shavings are generated and scattered inside the housing 1. The negative pressure fan 6 is activated and the shavings are extracted through the fan hood 5, thus keeping the inside of the housing 1 clean. After cutting is completed, the drive mechanism 37 operates in reverse, controlling the clamping block 38 to release the pipe from its fixation. At this point, the pipe can continue to be pushed, allowing the cut pipe to be pushed out from the rear of the housing 1 for the next round of cutting. This cycle is repeated to perform multiple consecutive cuts of a batch of pipes, greatly improving cutting efficiency.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
