Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a fixing structure for laser cutting machine parts. Background Technology

[0002] Laser cutting boasts advantages such as high precision, high speed, and smooth cuts, leading to its widespread application in numerous fields including machinery manufacturing, automotive, electronics, and aerospace. With the increasing prevalence of laser cutting machines, the requirements for object fixation during the cutting process are becoming increasingly stringent. Ensuring object stability during cutting is crucial to fully leveraging the advantages of laser cutting and improving cutting quality and efficiency.

[0003] The existing laser cutting machine object fixing structure has a poor fixing effect, cannot be adjusted according to the curved or sharp edges of the object being clamped, has significant limitations, and is not very practical. Furthermore, the object may move during cutting, and the clamp cannot be adjusted in multiple directions, further complicating its practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of poor fixing effect in the existing technology, inability to adjust according to the arc or edge of the clamped object, large limitations, poor practicality, and the phenomenon that the object may move during cutting, and the inability to adjust the clamping plate in multiple directions. Therefore, a laser cutting machine object fixing structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laser cutting machine object fixing structure, including a collar, four supports evenly distributed at the top of the collar, a first telescopic rod installed on the inner wall of the supports, a movable frame fixed to the output end of the first telescopic rod, a second telescopic rod installed on the inner top wall of the movable frame, a movable block fixed to the output end of the second telescopic rod, a third telescopic rod provided on one side of the movable block, the output end of the third telescopic rod passing through the movable block and fixed to a support plate, a motor installed at one end of the support plate, a prismatic clamping block fixed to the output end of the motor, a fourth telescopic rod installed inside the prismatic clamping block, a connecting plate fixed to the output end of the fourth telescopic rod, and multiple arc-shaped clamping blocks fixed to the end of the connecting plate away from the fourth telescopic rod.

[0006] Preferably, the top outer wall of the collar is fixed with a toothed edge, and a stabilizing plate is rotatably connected between the support plate and the prismatic clamping block on the outside of the motor.

[0007] Preferably, mounting plates are fixed to both sides of the bottom end of the bracket, and both mounting plates are fixed to the collar by bolts.

[0008] Preferably, one end of the movable block is fixed to a fixing frame, and the landing end of the second telescopic rod is installed on the end of the fixing frame facing the movable block.

[0009] Preferably, the movable block has a connecting groove that matches the second telescopic rod.

[0010] Preferably, the prismatic clamping block has an inner cavity, and the fourth telescopic rod, connecting plate and arc-shaped clamping block are all located in the inner cavity. One end of the prismatic clamping block has a connecting hole that matches the arc-shaped clamping block, and the connecting hole is connected to the inner cavity.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the opposing surfaces of an object with sharp edges can be clamped and fixed by the opposite movement of two prismatic clamping blocks. The synchronous operation of two fourth telescopic rods drives two connecting plates to move towards each other, thereby moving two sets of arc-shaped clamping blocks out of the two prismatic clamping blocks. When the two prismatic clamping blocks move towards each other, the two sets of arc-shaped clamping blocks can contact the object beforehand, clamping and fixing the curved edges at both ends of the object. Furthermore, the clamping angle of the arc-shaped clamping blocks can be adjusted by the operation of the motor, enhancing practicality. Additionally, the device can drive the entire moving frame to move laterally by the operation of the first telescopic rod, and the moving block can be raised and lowered by the operation of the second telescopic rod, thereby adjusting the position of the prismatic clamping blocks. This facilitates adjustment based on the movement of the object during cutting, further enhancing practicality. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a laser cutting machine object fixing structure, including a collar 1, four supports 3 evenly distributed at the top of the collar 1, a first telescopic rod 6 installed on the inner wall of the support 3, a movable frame 7 fixed at the output end of the first telescopic rod 6, a second telescopic rod 8 installed on the inner top wall of the movable frame 7, a movable block 9 fixed at the output end of the second telescopic rod 8, a third telescopic rod 11 provided on one side of the movable block 9, the output end of the third telescopic rod 11 passing through the movable block 9 and fixed with a support plate 12, a motor 14 installed at one end of the support plate 12, a prismatic clamping block 15 fixed at the output end of the motor 14, a fourth telescopic rod 18 installed inside the prismatic clamping block 15, a connecting plate 19 fixed at the output end of the fourth telescopic rod 18, and multiple arc-shaped clamping blocks 20 fixed at the end of the connecting plate 19 away from the fourth telescopic rod 18.

[0021] The overall effect of Embodiment 1 is that by moving the two prismatic clamping blocks 15 towards each other, the opposite surfaces of the object with sharp edges can be clamped and fixed. By operating the two fourth telescopic rods 18 synchronously, the two connecting plates 19 are driven to move towards each other, thereby moving the two sets of arc-shaped clamping blocks 20 out of the two prismatic clamping blocks 15. At this time, when the two prismatic clamping blocks 15 move towards each other, the two sets of arc-shaped clamping blocks 20 can contact the object in advance, and can clamp and fix the positions of the object with arc edges at both ends. Moreover, by operating the motor 14, the clamping angle of the arc-shaped clamping blocks 20 can be adjusted, making it more practical. In addition, by operating the first telescopic rod 6, the device can drive the entire moving frame 7 to move laterally. By operating the second telescopic rod 8, the moving block 9 can be raised and lowered, thereby driving the entire prismatic clamping block 15 to adjust its position, which is convenient for adjusting the movement of the object during cutting, making it more practical.

[0022] Example 2, as Figure 1-4 As shown, the top outer wall of the collar 1 is fixed with a toothed edge 2. A stabilizing plate 16 is rotatably connected between the support plate 12 and the prismatic clamping block 15 located outside the motor 14. Mounting plates 4 are fixed on both sides of the bottom end of the bracket 3. Both mounting plates 4 are fixed to the collar 1 by bolts 5. A fixing frame 10 is fixed to one end of the moving block 9. The sitting end of the second telescopic rod 8 is installed on the end of the fixing frame 10 facing the moving block 9. A connecting groove 13 matching the second telescopic rod 8 is opened in the moving block 9. An inner cavity 17 is opened in the prismatic clamping block 15. The fourth telescopic rod 18, the connecting plate 19 and the arc-shaped clamping block 20 are all located in the inner cavity 17. A connecting hole 21 matching the arc-shaped clamping block 20 is opened at one end of the prismatic clamping block 15, and the connecting hole 21 is connected to the inner cavity 17.

[0023] The overall effect of embodiment 2 is that, through the setting of the toothed edge 2, the roller ring 1 can be driven to rotate by the external drive structure, thereby driving the four prismatic clamping blocks 15 to rotate around the object, and the position to be clamped can be adjusted, making it more practical. Through the setting of the mounting plate 4 and bolts 5, other supports 3 can be installed on the ring 1 by rotation. Through the setting of the stabilizing plate 16, the prismatic clamping blocks 15 can be auxiliaryly supported, avoiding the problem of damage caused by the motor 14 supporting the prismatic clamping blocks 15 alone, thus making it more stable.

[0024] Working principle: When using this device, a cavity matching the collar 1 is pre-cut on the worktable of the laser cutting machine. The collar 1 is then installed and rotatably connected to the worktable. At this point, the gears of an external drive device mesh with the toothed edge 2. The operation of the external drive device drives the toothed edge 2 and the collar 1 to rotate as a whole, thereby causing the four prismatic clamping blocks 15 to rotate around the object, adjusting their clamping positions. The synchronous operation of the two third telescopic rods 11 causes the two opposing sets of prismatic clamping blocks 15 to move towards each other, clamping and fixing the object on all four sides. The opposite movement of two prismatic clamping blocks 15 clamps and fixes the opposite faces of the object with sharp edges. The synchronous operation of the four telescopic rods 18 drives the two connecting plates 19 to move towards each other, thereby moving the two sets of arc-shaped clamping blocks 20 out of the two rhomboid clamping blocks 15. At this time, when the two rhomboid clamping blocks 15 move towards each other, the two sets of arc-shaped clamping blocks 20 can contact the object in advance, and can clamp and fix the object at the position with arc edges at both ends. Moreover, through the operation of the motor 14, the clamping angle of the arc-shaped clamping blocks 20 can be adjusted, making it more practical. In addition, through the operation of the first telescopic rod 6, the device can drive the moving frame 7 to move laterally as a whole. Through the operation of the second telescopic rod 8, the moving block 9 can be raised and lowered, thereby driving the rhomboid clamping blocks 15 to adjust their position as a whole, which is convenient for adjusting the movement of the object during cutting, making it more practical.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
