The cutting worktable adopts a cubic structure and is made of cast iron. Furthermore, a workpiece groove is set in the middle of the cutting worktable. During processing, the workpiece is placed in the workpiece groove. The laser beam quality is stable, the cutting efficiency is high, and the service life is long.

[0004] However, laser cutting machines have limited functionality and can only position parts of a single specification. They cannot reliably limit the cutting of parts of different specifications, which affects the overall stability and accuracy of laser cutting. Utility Model Content

[0005] The purpose of this invention is to provide a laser cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting machine, including a working chamber, a central controller installed on the right side of the front end of the working chamber, a display screen on the top of the central controller, a working cavity inside the left side of the working chamber, a fixing plate fixedly connected to the rear end of the working cavity, a linear motor inside the fixing plate, a laser cutting head fixedly connected to the front end of the linear motor, a vacuum cleaner outside the laser cutting head, and a clamping mechanism and a loading and unloading mechanism. The clamping mechanism is used for limiting the cutting of different specifications of parts, and the loading and unloading mechanism is used for installing and removing the vacuum cleaner from the laser cutting head.

[0007] Preferably, the central controller is used to control and start the electrical equipment inside the cutting machine, and a sealed chamber door is installed at the front end of the working chamber.

[0008] Preferably, the clamping mechanism includes hollow seats fixedly connected to the left and right sides of the bottom end of the working cavity. A limiting slide rod is slidably connected to the inner side of the hollow seat. A sealing sleeve is fixedly connected inside the hollow seat. The sealing sleeve is filled with electrorheological fluid. A second spring is fixedly connected inside the sealing sleeve. A conductive sheet is fixedly connected to the outer side of the hollow seat. A power supply is fixedly connected to the left and right sides of the bottom end of the working cavity. A first connecting seat is fixedly connected to the inner side of the limiting slide rod. A fixing rod is fixedly connected to the inner top of the first connecting seat. A slider is slidably connected to the outer side of the fixing rod. A third spring is fixedly connected to the outer side of the slider. A pressure sensor is fixedly connected to the center position of the inner side of the first connecting seat. A second connecting seat is fixedly connected to the bottom end of the slider. Rollers are equidistantly and evenly rotatably connected to the lower surface of the second connecting seat. A servo motor is fixedly connected to the center position of the top end of the second connecting seat. The output shaft end of the servo motor is equipped with the roller at the center position of the lower surface of the second connecting seat.

[0009] Preferably, the sealing sleeve is made of conductive rubber, and the elastic force of the third spring is less than that of the second spring.

[0010] Preferably, the loading and unloading mechanism includes a take-up shaft rotatably connected to the center of the right side of the working chamber, a torsion spring coaxially fixed to the rear end of the take-up shaft, a slot provided at the center of the right side of the laser cutting head, a locking block movably connected to the inside of the right side of the vacuum cleaner and engaging with the slot, a movable block fixed to the right side of the locking block, a first spring fixed to the right side of the movable block, a pull rope fixed to the center of the right side of the movable block, and the right side of the pull rope fixed to the take-up shaft.

[0011] Preferably, the pull rope is wound with multiple strands on the take-up shaft, and the length of the pull rope is less than the moving length of the linear motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of laser cutting machine has a clamping mechanism at the bottom of the working cavity. When the workpiece to be cut is placed in the center of the clamping mechanism, the rotating roller on the clamping mechanism contacts the workpiece. The second connecting seat drives the slider to squeeze the third spring. At the same time, the first connecting seat squeezes the second spring in the sealing sleeve through the limiting slide rod. The reaction force of the squeezed second spring can push the first connecting seat to move through the limiting slide rod, and the first connecting seat pushes the rotating roller to fit against the outer surface of the workpiece through the second connecting seat. At this time, the outer side of the second connecting seat is in close contact with the pressure sensor on the first connecting seat. The pressure sensor senses the pressure and can control the power supply to start the power supply through the central controller. At this time, the power supply to the conductive sheet can supply power to the electrorheological fluid in the sealing sleeve and solidify the electrorheological fluid, thus fixing the position of the clamping mechanism. This effectively performs the positioning of workpieces of different specifications. The servo motor in the second connecting seat can drive the rotating roller at the center of the second connecting seat to rotate, thereby controlling the longitudinal position adjustment of the clamped workpiece and improving the overall applicability and stability of the laser cutting machine. 2. This type of laser cutting machine features a vacuum cleaner mounted on the outside of the laser cutting head. The vacuum cleaner's position is fixed outside the laser cutting head by a locking block inside the vacuum cleaner that engages with a slot on the laser cutting head. When the linear motor drives the laser cutting head to move from right to left, the vacuum cleaner pulls the cord on the take-up shaft to release the wire. Once the wire release is complete, as the laser cutting head continues to move the vacuum cleaner, the cord can be pulled out of the slot on the laser cutting head by a movable block. The vacuum cleaner can then be removed from the laser cutting head for inspection and maintenance. This modular design increases the functionality of the laser cutting machine while improving the convenience of its inspection and maintenance. Attached Figure Description

[0016] 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.

[0017] like Figure 1-6 As shown, this utility model has the following two specific embodiments.

[0018] Example 1 A laser cutting machine includes a working chamber 1, a central controller 101 installed on the right side of the front end of the working chamber 1, a display screen 102 on the top of the central controller 101, a working cavity 2 inside the left side of the working chamber 1, a fixing plate 202 fixedly connected to the rear end of the working cavity 2, a linear motor 203 inside the fixing plate 202, a laser cutting head 3 fixedly connected to the front end of the linear motor 203, a vacuum cleaner 4 outside the laser cutting head 3, and a clamping mechanism and a loading and unloading mechanism. The clamping mechanism is used for limiting the cutting of different specifications of cutting parts, and the loading and unloading mechanism is used for installing and removing the vacuum cleaner 4 on the laser cutting head 3. When the linear motor 203 is started, it can drive the laser cutting head 3 to move laterally back and forth inside the working cavity 2. At the same time, when the vacuum cleaner 4 is started, it can suck the exhaust gas generated by the laser cutting head 3 into the cavity and centrally transport and filter it through the air supply pipe.

[0019] The central controller 101 is used to control and start the electrical equipment inside the cutting machine, and a sealed chamber door 201 is installed at the front end of the working chamber 2.

[0020] The clamping mechanism includes hollow seats 5 fixedly connected to the left and right sides of the bottom end of the working chamber 2. A limit slide rod 501 is slidably connected to the inside of the hollow seats 5. A sealing sleeve 502 is fixedly connected inside the hollow seats 5, and the inside of the sealing sleeve 502 is filled with electrorheological fluid. A second spring 503 is fixedly connected inside the sealing sleeve 502. A conductive sheet 504 is fixedly connected to the outside of the hollow seats 5. A power supply 206 is fixedly connected to the left and right sides of the bottom end of the working chamber 2. A first connecting seat 6 is fixedly connected to the inside of the limit slide rod 501. A [missing information - likely a component or material] is fixedly connected to the top of the first connecting seat 6. A fixed rod 601 is slidably connected to a slider 602. A third spring 603 is fixed to the outside of the slider 602. A pressure sensor 604 is fixed to the center of the inner side of the first connecting seat 6. A second connecting seat 7 is fixed to the bottom end of the slider 602. A rotating roller 8 is equidistantly and evenly rotatably connected to the lower surface of the second connecting seat 7. A servo motor 701 is fixed to the center of the top end inside the second connecting seat 7. The rotating roller 8 at the center of the lower surface of the second connecting seat 7 is mounted on the output shaft end of the servo motor 701. When the first connecting seat 6 comes into contact with the workpiece, the second connecting seat 7 can push the slider 602 to compress the third spring 603. At the same time, the first connecting seat 6 can compress the second spring 503 inside the hollow seat 5 through the limiting slide rod 501. At this time, due to the reaction force of the second spring 503 being compressed, the first connecting seat 6 can push the rotating roller 8 on the second connecting seat 7 to press against the outer surface of the workpiece. At the same time, the outer side of the second connecting seat 7 can press the pressure sensor 604 on the first connecting seat 6. At this time, the pressure sensor 604 can sense that the pressure signal exceeds the threshold and input the signal into the central controller 101, causing the central controller 101 to control the start of the power supply 206. At this time, the power supply 206 can energize the sealing sleeve 502 through the conductive sheet 504, so that the electrorheological fluid inside the sealing sleeve 502 is energized and solidified, which can complete the position fixation of the limiting slide rod 501, the first connecting seat 6, the second connecting seat 7, and the rotating roller 8, and stably perform the workpiece clamping work. At the same time, the servo motor 701 on the second connecting seat 7 can start and drive the rotating roller 8 to rotate. At this time, the rotating roller 8 can push the clamped workpiece to adjust its longitudinal position.

[0021] The sealing sleeve 502 is made of conductive rubber, and the elastic force of the third spring 603 is less than that of the second spring 503.

[0022] Example 2 The difference from Embodiment 1 is that this embodiment discloses a loading and unloading mechanism for disassembling and replacing the vacuum cleaner 4 on the laser cutting head 3: The loading and unloading mechanism includes a take-up shaft 204 rotatably connected to the center of the right side of the working chamber 2. A torsion spring 205 is coaxially fixed to the rear end of the take-up shaft 204. A slot 301 is provided at the center of the right side of the laser cutting head 3. A locking block 401 is movably connected to the inside of the right side of the vacuum cleaner 4, which engages with the slot 301. A movable block 402 is fixed to the right side of the locking block 401. A first spring 403 is fixed to the right side of the movable block 402. A pull rope 404 is fixed to the center of the right side of the movable block 402. The right side of the pull rope 404 is fixed to the take-up shaft 204. The linear motor 203 drives the laser cutting head 3 and the vacuum cleaner 4 to move to the left. At this time, the vacuum cleaner 4 can pull the pull rope 404 to release the wire, and the pull rope 404 drives the take-up shaft 204 to rotate while twisting the torsion spring 205. When the wire release by the pull rope 404 is finished, as the vacuum cleaner 4 continues to move, the pull rope 404 can be moved by the movable block 402 to pull the locking block 401. When the laser cutting head 3 and the vacuum cleaner 4 move from left to right, the reaction force of the torsion spring 205 being twisted can drive the pull rope 404 to quickly rewind through the take-up shaft 204.

[0023] The pull rope 404 has multiple strands wound on the take-up shaft 204. The length of the pull rope 404 is less than the moving length of the linear motor 203. In addition, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0024] In this embodiment, when in use: the sealed chamber door 201 is opened, and the workpiece to be cut can be placed inside the bottom of the working chamber 2. At this time, the left and right sides of the workpiece are in contact with the rotating rollers 8 on the clamping mechanism. The rotating rollers 8 can push the slider 602 through the second connecting seat 7 to squeeze the third spring 603. At the same time, the first connecting seat 6 can squeeze the second spring 503 inside the hollow seat 5 through the limiting slide rod 501. At this time, due to the reaction force of the second spring 503 being squeezed, the rotating rollers 8 on the second connecting seat 7 can be pushed by the first connecting seat 6 to press against the outer surface of the workpiece. At this time, the outer side of the second connecting seat 7... Pressing the pressure sensor 604 allows the pressure sensor 604 to control the power supply 206 to be energized via the central controller 101. At this time, the power supply 206 can energize the sealing sleeve 502 through the conductive sheet 504, thereby energizing and solidifying the electrorheological fluid inside the sealing sleeve 502. This can fix the positions of the limit slide bar 501, the first connecting seat 6, the second connecting seat 7, and the rotating roller 8, and stably perform the workpiece clamping work. The linear motor 203 drives the laser cutting head 3 to move, which can effectively perform workpiece cutting work. At the same time, the vacuum cleaner 4 can suck the gas generated during cutting into the interior for centralized treatment.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
