DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 , Figure 2 As shown, Figure 1 The front view of the laser cutting machine in the embodiment is shown. Figure 2 Shown is a partial schematic diagram of a clamping assembly in an embodiment;

[0025] The device includes:

[0026] Workbench;

[0027] The clamping assembly includes a support frame 21 symmetrically arranged on the workbench, a frame body 22 is rotatably arranged on one end of the support frame 21 close to each other, a bidirectional threaded rod 23 is rotatably arranged on the frame body 22, and sleeve blocks 24 are threadedly sleeved on opposite threaded sections of the bidirectional threaded rod 23, and mounting blocks 25 are arranged on one end of the sleeve blocks 24 on both sides close to each other, and a clamping block 26 is detachably arranged on the mounting block 25;

[0028] By rotating the bidirectional threaded rod 23 , the two sleeve blocks 24 on the same side approach each other, driving the corresponding clamping blocks 26 to approach each other to clamp the ends of the special-shaped part 1 . The symmetrically arranged clamping blocks 26 clamp the two ends of the special-shaped part 1 .

[0029] The end face of the clamping block 26 in contact with the special-shaped part 1 matches the shape of the special-shaped part 1, ensuring stable clamping of the special-shaped part 1; the clamping block 26 is detachably mounted on the mounting block 25, and the clamping block 26 can be replaced, so that when clamping different special-shaped parts 1, the clamping block 26 that matches it can be replaced, thereby realizing the clamping and cutting of special-shaped parts 1 of different shapes, with greater flexibility.

[0030] The frame 22, the bidirectional threaded rod 23, the sleeve block 24 and the mounting block 25 cooperate with each other to realize the driving of the clamping block 26, so that it can smoothly realize the clamping action; specifically, one end of the sleeve block 24 away from the mounting block 25 is movably abutted against the side wall of the frame 22, and the frame 22 acts as a limiter to prevent the sleeve block 24 from rotating with the rotation of the bidirectional threaded rod 23, so that the sleeve blocks 24 can move closer to or away from each other with the rotation of the bidirectional threaded rod 23;

[0031] Furthermore, a guide rod is also provided on the frame 22, and the sleeve block 24 can move outside the guide rod along the length direction of the guide rod, further playing a guiding role and making the movement of the sleeve block 24 more stable.

[0032] like Figure 2 , Figure 3 As shown, Figure 2 Shown is a partial schematic diagram of a clamping assembly in an embodiment. Figure 3It shows Figure 2 A schematic diagram of the structure enlargement at point A;

[0033] The detachable structure includes a horizontally arranged plug rod 31 on the mounting block 25, a correspondingly arranged plug hole for the plug rod 31 to pass through on the clamping block 26, and a limit block 32 is also arranged on the mounting block 25, and the limit block 32 is movably arranged on the mounting block 25 to prevent the clamping block 26 from being separated from the end of the plug rod 31;

[0034] The detachable structure also includes a movable rod 33 fixedly arranged at the upper end of the limit block 32. The movable rod 33 extends out of the top of the mounting block 25 and is provided with a gripping portion. A spring 34 is also sleeved on the outside of the movable rod 33. The two ends of the spring 34 are respectively connected to the limit block 32 and the mounting block 25.

[0035] The detachable structure can realize the rapid replacement of the clamping block 26. Specifically, two groups of plug rods 31 are provided on one mounting block 25, and correspondingly, two groups of plug holes for the plug rods 31 to pass through are correspondingly provided on the clamping block 26. When installing the clamping block 26, the plug rods 31 are inserted into the corresponding plug holes on the clamping block 26 to realize the initial installation, and then the clamping block 26 is further limited and fixed by the provided limit blocks 32, movable rods 33 and springs 34. After the clamping block 26 is initially installed, the limit blocks 32 are abutted against the adjacent plug rods 31 and the side walls of the clamping block 26 under the action of the springs 34, thereby realizing the limit.

[0036] When the clamping block 26 needs to be removed, the gripping portion of the movable rod 33 is manually lifted, the spring 34 is compressed, and the limit block 32 is lifted to a position that does not affect the clamping block 26 from being separated from the insertion rod 31, so that the clamping block 26 can be removed.

[0037] like Figure 4 As shown, Figure 4 What is shown is a schematic diagram of the cooperation between the limit block and the clamping block in the embodiment;

[0038] A magnet 1 321 is further provided at one end of the limiting block 32 close to the insertion rod 31 , and an embedded magnet 261 is provided at a position on the insertion rod 31 corresponding to the magnet 1 321 , and the magnet 1 321 and the magnet 2 261 are attracted to each other.

[0039] When the limit block 32 is in the limit state, it abuts against the adjacent insertion rod 31. By setting the mutually attracted magnet 1 321 and the mutually attracted magnet 261, the effect of limiting the separation of the clamping block 26 is further ensured. The mutually attracted magnet 1 321 and the mutually attracted magnet 261 can be separated from each other under a certain external force.

[0040] like Figure 1 As shown, Figure 1 What is shown is a schematic diagram of the front view of the laser cutting machine in the embodiment;

[0041] A driving member 27 is also provided on the outside of one support frame 21, and a mounting shaft is provided at one end of the frame bodies 22 on both sides that are away from each other, and the mounting shaft is rotatably mounted on the support frame 21 on the corresponding side through a bearing, and the output end of the driving member 27 is connected to the mounting shaft on the side;

[0042] The driving member 27 is a motor. When both ends of the special-shaped part 1 are clamped by the clamping blocks 26, the driving member 27 is turned on to realize the rotation of the special-shaped part 1 during the cutting process, which is more flexible.

[0043] The workbench includes a base 11 and a mounting frame 12 . The clamping assembly is arranged on the base 11 . A laser cutter 40 is arranged on the mounting frame 12 at a position corresponding to the clamping assembly.

[0044] The laser cutter 40 cuts the workpiece and can move in horizontal and vertical directions to achieve the cutting action.

[0045] Working principle: When the device is in use, first switch the clamping block 26 according to the special-shaped part 1 to be cut: manually lift the gripping portion of the movable rod 33 to compress the spring 34, lift the limit block 32 to a position that does not affect the insertion of the clamping block 26 into the insertion rod 31, and release the movable rod 33 after the insertion rod 31 is smoothly inserted into the corresponding insertion hole on the clamping block 26. At this time, the limit block 32 is close to the insertion rod 31, and the magnet 1 321 and the magnet 2 261 are attracted to each other, so as to achieve stable and fast installation of the clamping block 26;

[0046] The two ends of the special-shaped part 1 are clamped by the clamping block 26: by rotating the bidirectional threaded rod 23, the two sleeve blocks 24 on the opposite threaded sections of the bidirectional threaded rod 23 are close to each other, thereby clamping the ends of the special-shaped part 1.

[0047] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
