Description

Technical Field

[0001] This utility model relates to the field of laser nozzle technology, and in particular to an angle-adjustable laser nozzle. Background Technology

[0002] In the field of laser processing, semi-automatic laser nozzles are key components widely used in processes such as cutting, welding, and cleaning. Their main function is to guide the laser beam and assist in gas ejection to achieve high-precision machining of the workpiece. Traditional semi-automatic laser nozzles typically employ a fixed-angle design or a limited angle adjustment mechanism, which presents significant limitations in practical applications.

[0003] Most semi-automatic laser nozzles currently on the market only support limited angle positioning and cannot achieve stepless adjustment, making them unsuitable for processing complex curved surfaces or special positions. Furthermore, they lack an active locking mechanism after adjustment, making them inconvenient for users. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an angle-adjustable laser nozzle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An angle-adjustable laser nozzle includes a frame and a nozzle main unit. A drive shaft is mounted on the nozzle main unit via a fixed column, and the drive shaft is inserted into the frame. Stops are movably arranged on the frame on both the upper and lower sides of the fixed column. Fixing frames are fixedly arranged on the frame on both the left and right sides of the stops. The stops are guided to move by vertical guide columns on the fixing frames, and each fixing frame has a movable frame for locking the stops.

[0006] In addition, a preferred structure is that side plates are fixedly installed on both the upper and lower sides of the fixing frame, and vertical guide columns are fixedly installed between the side plates on both sides, with a fixing ring fixedly installed in the middle of each vertical guide column.

[0007] In addition, a preferred structure is that outer plates are fixedly provided on both sides of the stop member, and the outer plates are guided to move by vertical guide columns.

[0008] In addition, a preferred structure is that multiple horizontal guide columns are fixedly arranged between the side plate and the frame, and springs are installed on the side plate facing the frame.

[0009] In addition, a preferred structure is that guide plates are fixedly installed on both the upper and lower sides of the movable frame, the guide plates are guided to move by horizontal guide columns, and the other end of the spring is connected to the guide plate.

[0010] In addition, a preferred structure is that locking plates are fixedly provided at both ends of the movable frame, and the locking plates are adapted to the outer plate.

[0011] The beneficial effects of this utility model are as follows: the nozzle host is rotated by the transmission shaft, which can realize stepless angle adjustment. The movable frame drives the locking plate to cooperate with the outer plate on the stop, and the fixed column is locked under the preload of the spring. This can effectively prevent the nozzle from loosening or shifting during processing. The device has a simple and convenient structure, which improves the flexibility of angle adjustment and the stability of locking. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-6 An angle-adjustable laser nozzle includes a frame 1 and a nozzle host 2. A drive shaft 22 is mounted on the nozzle host 2 via a fixed column 21, and the drive shaft 22 is inserted into the frame 1. Stops 5 are movably arranged on the frame 1 on both the upper and lower sides of the fixed column 21. Fixing frames 3 are fixedly arranged on the frame 1 on both the left and right sides of the stop 5. The stop 5 is guided to move by vertical guide columns 32 on the fixing frames 3, and each fixing frame 3 is movably arranged with a movable frame 4 for locking the stop 5.

[0016] The fixed frame 3 has side plates 31 fixedly installed on both its upper and lower sides, and vertical guide posts 32 fixedly installed between the side plates 31. A fixing ring 321 is fixedly installed in the middle of each vertical guide post 32. The stop member 5 has outer plates 51 fixedly installed on both sides, and the outer plates 51 are guided to move by the vertical guide posts 32. The fixing rings 321 limit the movement distance of the outer plates 51 on both sides.

[0017] Multiple horizontal guide columns 33 are fixedly installed between the side plate 31 and the frame 1, and springs 34 are installed on each side plate 31 facing the frame 1. Guide plates 42 are fixedly installed on the upper and lower sides of the movable frame 4. The guide plates 42 are guided to move by the horizontal guide columns 33, and the other end of each spring 34 is connected to the guide plate 42. The springs 34 provide a preload force to the movable frame 4, ensuring that the movable frame 4 can be locked to the outside of the outer plates 51 on both sides. It is worth noting that the springs 34 are high-strength anti-vibration springs in the prior art to ensure that they still have sufficient preload force in extreme environments. The springs 34 are prior art and are not related to the technical problem of easy angle adjustment that needs to be solved in this technical solution, so they will not be described in detail in this application.

[0018] The movable frame 4 has locking plates 41 fixedly installed at both ends, and the locking plates 41 are adapted to the outer plate 51.

[0019] In this embodiment, the rotation of the drive shaft 22 drives the nozzle host 2 to rotate, thereby achieving stepless angle adjustment of the nozzle host 2. Furthermore, the drive shaft 22 is equipped with a damping system, as is common in the prior art, to ensure its stability after rotation. These are all prior art technologies and will not be elaborated upon further. Next, a locking mechanism additionally provided in this application is used for further locking.

[0020] Furthermore, when rotating the nozzle host 2, simply pull the movable frames 4 on both sides outward through the horizontal guide columns 33 to release the locking plate 41 from locking the outer plates 51 on both sides. At this time, the stoppers 5 on both sides will loosen. Then, simply rotate the nozzle host 2 directly. When it is adjusted to a suitable angle, simply pull the stoppers 5 on the upper and lower sides towards the center. This will clamp the fixed column 21 through the stoppers 5, thus locking the nozzle host 2 after adjustment.

[0021] When the stoppers 5 on both sides clamp the fixed post 21, the outer plates 51 on both the upper and lower sides are located in the middle. At this time, the movable frame 4 can automatically reset by the elastic force of the spring 34, and the locking plate 41 can be clamped between the outer plates 51 on both the upper and lower sides to fix the stoppers 5, thereby locking the nozzle host 2.

[0022] Furthermore, coarsely ground anti-slip pads are provided on the contact surfaces between the stop 5 and the fixing post 21 to improve their stability during locking. Also, when the locking plate 41 clamps the outer plates 51 on both sides, the outer side of the locking plate 41 is also clamped by the side plates 31 to ensure the clamping effect on the outer plates 51. At this time, the elastic preload of the spring 34 further ensures the locking effect.

[0023] In this invention, the nozzle host 2 is rotated by the transmission shaft 22, which can achieve stepless angle adjustment. The movable frame 4 drives the locking plate 41 to cooperate with the outer plate 51 on the stop 5, and the fixed column 21 is locked under the preload of the spring 34. This can effectively prevent the nozzle from loosening or shifting during processing. The device has a simple and convenient structure, improves the flexibility of angle adjustment and locking stability, and is easy for users to use.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
