[0007] A connecting plate is fixed to the vertical side of another movable frame, and an inlay plate is welded to the other side of the connecting plate. The outer periphery of the connecting plate and the inlay plate are respectively tightly attached to an inner ring and a collar, and the inner ring is fixed to the inner periphery of the collar.

[0008] In a further embodiment, a fixing plate is welded to the vertical inner wall of each of the two connecting frames, and a connecting frame of the same size is fixed to the other side of the collar. Telescopic rods are installed on both sides of the two fixing plates, and clamping plates are installed on the moving parts of the four telescopic rods. A second lead screw is inserted into the vertical inner wall of the two vertical frames through bearings. A second motor that provides power to the second lead screw is installed at the top of each of the two vertical frames, and the moving frame is sleeved on the outer periphery of the second lead screw through ball nuts.

[0009] In a further embodiment, a second linear motor is mounted on the top of the housing, and a laser cutting head for cutting is mounted on the drive end of the second linear motor.

[0010] In a further embodiment, a groove is provided on the vertical side of the box, and a first linear motor is installed at the top of the box. A partition that fits the inner wall of the groove is installed at the drive end of the first linear motor.

[0011] In a further embodiment, two fixing plates are installed on the vertical side of the box, and a collection box that fits the box is fixed between the two fixing plates.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] In use, the laser cutting bed local positioning device uses a first motor located on the vertical side of the bottom frame to drive the vertical frames on both sides to move towards each other, causing the two connecting frames to move closer or further apart. Then, the two connecting frames are brought to the same height. The fixing plate located on the vertical inner wall of the connecting frame extends and retracts through the telescopic rods on both sides of the fixing plate, so that the clamping plates on both sides can locally position and clamp the parts, thereby facilitating the clamping and fixing of parts of different sizes.

[0016] During processing, a fan is used to draw in air, causing dust and impurities to adhere to the surface of the filter screen. After a certain period of time, the fixing block set on the vertical side of the box is removed, allowing the collection box to fall off. Then, the collection box is moved, causing the insert frame to disengage from the slot. As the slot moves out of the box, the debris and impurities attached to the bottom surface of the filter screen are scraped off, making it easier to collect debris and impurities during the cutting process.

[0017] This laser cutting bed partial positioning device, after clamping the component, allows for multi-faceted processing. A second rotary motor on the vertical side of the connecting frame controls the frame's rotation, causing it to rotate synchronously via a side-connecting component. This rotation, limited by the collar and inner ring on the inlay disc, enables the component to rotate automatically, switching cutting surfaces. Alternatively, the second motor at the top of the vertical frame lowers the moving frame, placing the component on top of the disc. The first rotary motor then rotates, adjusting the component's orientation before clamping and fixing it again for cutting. This differs from existing devices that cannot effectively perform multi-faceted processing and require manual flipping. This device facilitates automatic multi-faceted processing of components of different sizes, saving manpower and improving efficiency. Furthermore, this laser cutting bed partial positioning device facilitates clamping and fixing of components of different sizes, collects debris and impurities during cutting, and enables automatic multi-faceted processing of components of different sizes, saving manpower and improving efficiency.

[0030] Example

[0031] Please see Figures 1 to 6The base 4 and the housing 1, which is set on top of the base 4 to protect the laser cutting bed, constitute the main body of the cutting bed. A bottom frame 11 is fixed to the inner bottom wall of the base 4. A first motor 15 is installed on the vertical side of the bottom frame 11. A first bidirectional lead screw with its end inserted into the bottom frame 11 is installed at the drive end of the first motor 15. Two vertical frames 22 are sleeved on the outer periphery of the first bidirectional lead screw. A fixed frame 14 is connected to the top of the bottom frame 11. A first rotary motor 23 is installed on the inner bottom wall of the fixed frame 14. A disc 19 is sleeved on the drive end of the first rotary motor 23 through a first rotating rod. A movable frame 24 is tightly attached to the vertical inner wall of both vertical frames 22. A second rotary motor 25 is installed on the vertical inner wall of one of the movable frames 24. A connecting rod is sleeved on the drive end of the second rotary motor 25 through a second rotating rod. A connecting plate 28 is fixed to the vertical side of frame 16 and another movable frame 24. An inlay plate 29 is welded to the other side of the connecting plate 28. After the component is clamped, if multi-sided processing is required, the second rotary motor 25 set on the vertical side of the connecting frame 16 controls the connecting frame 16 to rotate. The connecting frame 16 is connected to the side, and the other connecting frame 16 rotates synchronously under the limitation of the inlay plate 29 by the collar 26 and the inner ring 27. This allows the component to rotate automatically and switch the cutting surface. Alternatively, under the action of the second motor 17 at the top of the vertical frame 22, the movable frame 24 is lowered and the component is placed on the top of the disc 19. The first rotary motor 23 rotates to adjust the orientation of the component. Then, it is clamped and fixed again for cutting processing.

[0032] This device differs from existing devices that cannot effectively process components from multiple sides and require manual flipping. During use, this device facilitates automatic processing of top components of different sizes from multiple sides, saving manpower and improving efficiency. The outer periphery of the connecting plate 28 and the inlay plate 29 are respectively tightly attached to the inner ring 27 and the collar 26, and the inner ring 27 is fixed to the inner periphery of the collar 26. The other side of the collar 26 is fixed with a connecting frame 16 of the same size.

[0033] The vertical inner walls of the two connecting frames 16 are welded with fixing plates 21, and telescopic rods 20 are installed on both sides of the two fixing plates 21. Clamping plates 18 are installed on the moving parts of the four telescopic rods 20. The vertical inner walls of the two vertical frames 22 are fitted with second lead screws through bearings. The top of the two vertical frames 22 is fitted with a second motor 17 that provides power to the second lead screw. The moving frame 24 is sleeved on the outer periphery of the second lead screw through ball nuts. The top of the housing 1 is fitted with a second linear motor 9. The drive end of the second linear motor 9 is fitted with a laser cutting head 13 for cutting.

[0034] The vertical side of the housing 1 has a groove. The top of the housing 1 is equipped with a first linear motor 2. The drive end of the first linear motor 2 is equipped with a partition 3 that fits into the inner wall of the groove. Two fixing blocks 5 are installed on the vertical side of the housing 1. A collection box 7 that fits into the housing 1 is fixed between the two fixing blocks 5. The vertical side of the housing 1 has a slot. The vertical side of the collection box 7 is equipped with a frame 30 that fits into the inner wall of the slot. A filter screen 12 that is flush with the top wall of the slot is fixed on the vertical side of the housing 1. A top plate 6 is fixed to the inner wall of the collection box 7. Multiple fans 8 are installed on the top of the top plate 6.

[0035] The first linear motor 2, the second linear motor 9, the first motor 15, the second motor 17, the telescopic rod 20, the first rotary motor 23, the second rotary motor 25, and the fan 8 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0036] Working principle

[0037] When different sides of the laser cutting bed need to be cut, the second rotary motor 25 located on the vertical side of the moving frame 24 controls the connecting frame 16 to rotate, so that the connecting frame 16 on the other side can rotate synchronously in the limiting position of the collar 26 and the inner ring 27 on the inlay plate 29, so that the part can be flipped over. At the same time, the second motor 17 at the top of the vertical frame 22 controls the moving frame 24 to move down, placing the part on the top of the disc 19. The first rotary motor 23 rotates to adjust the orientation of the part, and then clamps and cuts it again, thus facilitating multi-sided processing.
