Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] When implementing: Figure 1-4 As shown, a fixture for a fiber laser cutting device includes a supporting base 1, a positioning base plate 2 and an adjusting box 5: the top outer wall of the supporting base 1 is slidably mounted with a positioning base plate 2, the side of the positioning base plate 2 is provided with an adjusting control mechanism 3, the top of the positioning base plate 2 is provided with a lifting control mechanism 4, the side of the lifting control mechanism 4 is provided with a clamping limit mechanism 6, the adjusting control mechanism 3 includes a limit frame 31, an extension plate 32, a mounting plate 33, a locking bolt 34 and a threaded hole 35, the outer walls on both sides of the positioning base plate 2 are symmetrically provided with limit frames 31, the limit frames 31 are set in an "L" shape, the outer walls of the sides of the supporting base 1 at the bottom are symmetrically provided with extension plates 32, the outer walls of the bottom end of the extension plates 32 are provided with mounting plates 33, and the mounting plates 34 are installed. The top outer wall of the mounting plate 33 is threadedly connected with a locking bolt 34, and the bottom outer wall of the mounting plate 33 is slidably installed with the top outer wall of the extension plate 32. The top outer wall of the extension plate 32 is evenly spaced with threaded holes 35, and the locking bolt 34 and the threaded holes 35 are threadedly connected; when the position of the positioning base plate 2 needs to be adjusted, the locking bolt 34 needs to be unscrewed from the inside of the mounting plate 33, and then the positioning base plate 2 is changed from a locked state to a movable state. Subsequently, the positioning base plate 2 is pushed to the appropriate position and the locking bolt 34 is screwed into the threaded hole 35 at the corresponding position. The setting of the extension plate 32 here serves as an auxiliary support for the mounting plate 33, and the setting of the limit frame 31 serves as a connection effect for the positioning base plate 2 and the mounting plate 33.

[0022] The lifting control mechanism 4 includes a first support column 41, a second support column 42, a control motor 43 and a limiting worm 44. The top outer wall of the positioning base plate 2 is provided with a first support column 41 and a second support column 42. The first support column 41 is arranged as a cavity structure, and the side outer wall of the first support column 41 is provided with a control motor 43. The control motor 43 is connected to one end of the limiting worm 44, and the other end of the limiting worm 44 is slidably installed with the side inner wall of the first support column 41. A limiting worm gear 45 is connected above the limiting worm 44, and the limiting worm gear 45 is arranged on the outside of the support shaft 46. Both ends of the support shaft 46 are rotatably installed with the side inner wall of the first support column 41. A limiting gear 47 is arranged on the outside of the support shaft 46. A limiting rack 48 is meshed with the side of the limiting gear 47. The limiting rack 48 is slidably installed with the side inner wall of the first support column 41. The limiting rack 48 is located on the side outer wall of the bottom end and is provided with a connecting block. When the adjusting box 5 is moved to the appropriate position, the control motor 43 can be turned off. Since the transmission of the limiting worm 44 and the limiting worm gear 45 has a self-locking function, the adjusting box 5 can still maintain the unchanged position after the control motor 43 is turned off. It is noted here that the setting of the second support column 42 has the effect of auxiliary support for the adjusting box 5.

[0023] The clamping limit mechanism 6 includes a driving motor 61, a reciprocating screw rod 62 and an auxiliary bar 63. The side inner wall of the adjusting box 5 is provided with a driving motor 61, the driving motor 61 is connected to one end of the reciprocating screw rod 62, and the other end of the reciprocating screw rod 62 is rotatably installed with the side inner wall of the adjusting box 5. The side of the reciprocating screw rod 62 is provided with an auxiliary bar 63 in parallel, and both ends of the auxiliary bar 63 are connected to the two side inner walls of the adjusting box 5. The reciprocating screw rod 62 and the auxiliary bar 63 are symmetrically provided with limit blocks 64 on the outside. The outer walls of both sides of the limit block 64 are provided with protrusions, and the protrusions are slidably installed with the side inner wall of the adjusting box 5, and the protrusions are connected to the side outer wall of the mounting member 65. The mounting member 65 is slidably installed with the side outer wall of the adjusting box 5, and the side outer wall of the mounting member 65 is provided with a supporting back plate 66, and the side outer wall of the supporting back plate 66 is provided with a resisting tooth pad 67; when it is necessary to limit the cutting piece At this time, it is necessary to first place the end of the workpiece above the positioning base plate 2 and ensure that the workpiece is located in the middle position of the two interference tooth pads 67, and then turn on the drive motor 61. When the drive motor 61 is turned on, it will automatically drive the reciprocating screw 62 to rotate and then drive the limit block 64 to move. Here, due to the setting of the auxiliary bar 63, the reciprocating screw 62 will only drive the limit block 64 to realize the horizontal sliding trajectory movement when rotating. Then the movement of the limit block 64 will automatically drive the mounting part 65 to move, and then the movement of the mounting part 65 will automatically drive the support back plate 66 to move and then drive the interference tooth pad 67 to move. As the two interference tooth pads 67 move in their trajectory, the workpiece will be automatically clamped in the middle position of the two interference tooth pads 67. At this time, the drive motor 61 can be turned off. It should be noted that the drive motor 61 has a self-locking function. After being turned off, the interference tooth pad 67 can still maintain its position unchanged after moving.

[0024] When the utility model is in use, when it is necessary to control the overall height of the adjustment box 5, it is necessary to first turn on the control motor 43. When the control motor 43 is turned on, it will automatically drive the limiting worm 44 to rotate and then drive the limiting worm gear 45 to rotate. Then, the limiting worm gear 45 will automatically drive the support shaft 46 to rotate when it rotates. When the support shaft 46 rotates, it will automatically drive the limiting gear 47 to rotate. Then, the limiting gear 47 will automatically drive the limiting rack 48 to move, and then the movement of the limiting rack 48 will automatically drive the connecting block to move and then drive the adjustment box 5 to move. After the section box 5 moves to the appropriate position, the control motor 43 can be turned off. Since the transmission of the limiting worm 44 and the limiting worm wheel 45 has a self-locking function, the adjustment box 5 can still maintain the same position after the control motor 43 is turned off. It is noted here that the setting of the second support column 42 has an auxiliary support effect on the adjustment box 5; when it is necessary to limit and clamp the workpiece to be cut, it is first necessary to place the end of the workpiece above the positioning base plate 2, and ensure that the workpiece is in the middle position of the two interfering tooth pads 67, and then turn on the drive motor 61. When the drive motor 61 is turned on, When the reciprocating screw 62 is rotated, the limit block 64 is automatically driven to move. Due to the setting of the auxiliary bar 63, the reciprocating screw 62 will only drive the limit block 64 to realize the sliding track movement in the horizontal direction when it rotates. Then the limit block 64 will automatically drive the mounting part 65 to move, and the movement of the mounting part 65 will automatically drive the support back plate 66 to move, and then drive the interference tooth pad 67 to move. As the two interference tooth pads 67 move along the track, the workpiece will be automatically clamped in the middle position of the two interference tooth pads 67. At this time, the drive motor 61 can be turned off. It is noted that the driving motor 61 has a self-locking function, and after being turned off, the abutting tooth pad 67 can still maintain the position after movement; when the position of the positioning base plate 2 needs to be adjusted, the locking bolt 34 needs to be unscrewed from the inside of the mounting plate 33, and then the positioning base plate 2 is changed from a locked state to a movable state, and then the positioning base plate 2 is pushed to the appropriate position and the locking bolt 34 is screwed into the threaded hole 35 at the corresponding position. The setting of the extension plate 32 here has an auxiliary supporting effect on the mounting plate 33, and the setting of the limit frame 31 has a connecting effect on the positioning base plate 2 and the mounting plate 33.

[0025] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
