Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a fixing and clamping module for laser-cut workpieces. Background Technology

[0002] Laser cutting is a processing technology that uses a high-energy-density laser beam to irradiate a workpiece, causing the workpiece material to melt, vaporize, or sublimate rapidly, thereby achieving the purpose of cutting. It is widely used in industries such as automobile manufacturing, aerospace, and machinery manufacturing to cut various metal sheets, such as stainless steel, carbon steel, and aluminum alloys. In addition, it also has important applications in the processing of non-metallic materials such as electronics, plastics, wood, and fabrics.

[0003] Currently, when laser cutting pipe-like workpieces, the two ends of the pipe are usually clamped and fixed. In order to further improve the stability of pipe-like workpieces during cutting, the outer wall of the pipe is also clamped in addition to the two ends. However, since the current clamping mechanism usually clamps the two ends first and then the outer wall of the pipe, the stroke is relatively long, which affects the processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fixing and clamping module for laser-cut workpieces to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixed clamping module for laser-cut workpieces includes a frame with a placement platform for placing the workpiece on the frame. The fixing mechanism includes: a first clamp fixedly mounted on the frame; a second clamp slidably mounted on the frame and positioned relative to the first clamp; multiple side clamps arranged in a circumferential direction and slidably connected to the frame; a transmission mechanism slidably mounted on the frame and movably connected to each side clamp; and a bidirectional screw rotatably connected to the frame and threadedly connected to the second clamp and the transmission mechanism, respectively, so that the second clamp and the transmission mechanism can move towards or away from each other.

[0007] Furthermore, the transmission device includes a transmission rod, which is U-shaped and has one end threadedly connected to a bidirectional screw. It is also rotatably connected to a plurality of connecting rods that correspond one-to-one with the pressure rods. The ends of the connecting rods are rotatably connected to the corresponding side pressure devices, and the other end of the transmission rod is slidably connected to a guide rod on the frame.

[0008] Furthermore, the side pressure device includes a slider slidably connected to the frame, one side of the slider being rotatably connected to the transmission rod, and the other side being provided with a pressing part.

[0009] Furthermore, the pressing part includes a second screw rotatably connected to the slider, a pressure rod threadedly connected to the second screw, the pressure rod being slidably connected to the slider, and a twist cap being connected to one end of the second screw through the slider.

[0010] Furthermore, the first clamp includes a first clamp plate fixedly connected to the frame.

[0011] Furthermore, the second clamp includes a clamping rod, which is U-shaped. One end of the clamping rod is threadedly connected to a bidirectional screw and a second clamping plate is fixedly connected to the end of the clamping rod. The other end is slidably connected to a guide rod on the frame.

[0012] Furthermore, the outer surface of the pressure rod is provided with an anti-slip pad.

[0013] In the above technical solution, the laser-cut workpiece fixing and clamping module provided by this utility model has the following beneficial effects:

[0014] By rotating the bidirectional screw through the established fixing mechanism, the second clamp and the transmission device move in opposite directions. The second clamp moves towards the first clamp to cooperate with it in clamping both ends of the workpiece. The transmission device moves away from the first clamp and drives each side pressure device to move towards the outer wall of the workpiece until the outer wall is clamped. This invention can simultaneously clamp and fix both ends and the outer wall of a pipe, providing a strong fixing effect and reducing clamping time, thereby improving processing efficiency.

[0015] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] Please see Figure 1-5 A laser-cut workpiece clamping module includes a frame 6, on which a workpiece placement platform 62 is provided. The module includes a fixing mechanism comprising: a first clamp 1 fixedly mounted on the frame 6; a second clamp 2 slidably mounted on the frame 6 and positioned relative to the first clamp 1; multiple side clamps 3 arranged in a circumferential pattern and slidably connected to the frame 6; a transmission device 4 slidably mounted on the frame 6 and movably connected to each side clamp 3; and a bidirectional screw 5 rotatably connected to the frame 6 and threadedly connected to both the second clamp 2 and the transmission device 4, allowing the second clamp 2 and the transmission device 4 to move towards or away from each other. It is understood that a motor is fixedly mounted on the frame 6, and the output end of the motor is fixedly connected to the end of the bidirectional screw 5, thereby providing driving force for the rotation of the bidirectional screw 5.

[0027] Furthermore, the transmission device 4 includes a transmission rod 41, which is U-shaped. One end of the transmission rod 41 is threadedly connected to the bidirectional screw 5 and is rotatably connected to a plurality of connecting rods 42 that correspond one-to-one with the pressure rod 33. The end of the connecting rod 42 is rotatably connected to the corresponding side pressure device 3, and the other end of the transmission rod 41 is slidably connected to the guide rod 61 on the frame 6.

[0028] When the bidirectional screw 5 rotates, the transmission rod 41 is slidably connected to the guide rod 61 and its rotation is restricted. Therefore, the rotation of the bidirectional screw 5 drives the transmission rod 41 to move along the axial direction of the bidirectional screw 5. The movement of the transmission rod 41 drives each side pressure unit 3 to slide on the frame 6 through the connecting rod 42.

[0029] Furthermore, the side pressure device 3 includes a slider 31 slidably connected to the frame 6. One side of the slider 31 is rotatably connected to the transmission rod 41, and the other side is provided with a pressing part. The transmission rod 41 drives the slider 31 to move on the frame 6 in a direction toward or away from the workpiece via the connecting rod 42. It is worth noting that the side pressure device 3 is arranged circumferentially and coaxially with the workpiece placed on the placement table 62, so that the side pressure device 3 can simultaneously press against the workpiece.

[0030] Furthermore, the pressing part includes a second screw 32 rotatably connected to the slider 31. A pressure rod 33 is threadedly connected to the second screw 32, and the pressure rod 33 is slidably connected to the slider 31. One end of the second screw 32 passes through the slider 31 and is connected to a cap 34. Some pipe-like workpieces are not perfectly circular and have an arc shape, making it difficult for the above structure to completely clamp the outer wall of the workpiece. By rotating the cap 34, the second screw 32 is driven to rotate, and the rotation of the second screw 32 drives the pressure rod 33 to move along the slider 31, thereby allowing individual adjustment of the distance between a single pressure rod 33 and the outer wall of the workpiece to clamp the outer surface of non-circular arc-shaped workpieces. It is understood that the cap 34 can be replaced with a motor, which is fixedly mounted on the slider 31 and fixedly connected to the second screw 32 to drive the second screw 32 to rotate, achieving electric adjustment.

[0031] Furthermore, the first clamp 1 includes a first clamp plate fixedly connected to the frame 6.

[0032] Furthermore, the second clamp 2 includes a clamping rod 21, which is U-shaped. One end of the clamping rod 21 is threadedly connected to the bidirectional screw 5 and a second clamping plate 22 is fixedly connected to the end. The other end is slidably connected to the guide rod 61 on the frame 6.

[0033] When the bidirectional screw 5 rotates, the clamping rod 21 is restricted from rotating by the guide rod 61. Therefore, the rotation of the bidirectional screw 5 drives the clamping rod 21 to move towards or away from the first clamp 1.

[0034] Furthermore, the outer surface of the pressure rod 33 is provided with an anti-slip pad to increase the friction with the outer wall of the workpiece.

[0035] Working principle: The rotation of the bidirectional screw 5 drives the transmission rod 41 to move along the axial direction of the bidirectional screw 5. The movement of the transmission rod 41 drives the slider 31 to move on the frame 6 in a direction toward or away from the workpiece to clamp the outer wall of the workpiece. At the same time, the rotation of the bidirectional screw 5 drives the clamping rod 21 to move toward or away from the first clamp 1 to clamp both ends of the workpiece. This utility model can simultaneously clamp and fix both ends of the pipe and the outer wall, with a strong fixing effect and reduced clamping time, thereby improving processing efficiency.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
