Description

Technical Field

[0001] This utility model relates to the field of laser welding machine fixture technology, specifically a positioning device for a laser welding machine. Background Technology

[0002] Laser welding machines, also known as laser welding machines or laser welding machines, are machines used for laser material processing. They are highly automated and have a simple welding process. According to their working method, they are divided into laser mold welding machines, automatic laser welding machines, laser spot welding machines, fiber optic transmission laser welding machines, etc. They can weld dots, lines, circles, squares, or any planar shapes drawn by AutoCAD software. When welding sheet metal workpieces, a positioning device is required to fix and position the sheet metal so that the welding machine can weld the sheet metal.

[0003] A search of the utility model patent with publication number CN215512310U reveals an auxiliary plate positioning device for a plastic laser welding machine. When clamping the plate workpiece, the first clamp holds the plate workpiece perpendicular to the horizontal plane, while the second clamp holds it parallel to the horizontal plane, thereby adjusting the vertical position of the two plates to be welded. This facilitates the welding and processing of different types of vertically connected products. However, in use, it can only perform vertical positioning for two plates and cannot perform acute or obtuse angle welding positioning according to the processing requirements of the workpiece, thus reducing its practicality. Therefore, this application proposes a positioning device for a laser welding machine. Utility Model Content

[0004] The purpose of this invention is that existing positioning devices can only position vertically and cannot position at acute or obtuse angles according to processing requirements. This invention provides a positioning device for laser welding machines.

A first positive and negative screw rod is rotatably threaded through the inner wall of the U-shaped plate on the opposite side. Both ends of the first positive and negative screw rod are threaded with pressure plates.

[0008] Furthermore, a groove is provided on the base, and a second positive and negative lead screw is rotatably inserted through the inner wall of the groove on opposite sides. Two adjusting plates are slidably inserted in the groove, and the two adjusting plates are respectively threaded onto the two ends of the second positive and negative lead screw.

[0009] Furthermore, a support plate is connected to the inner wall of the ring plate, and the support plate is connected to the adjustment plate. A clearance groove is provided through one side of the movable sleeve, and the support plate is inserted into the clearance groove.

[0010] Furthermore, a shaft is rotatably mounted on the adjusting plate, and a support plate is fixedly connected to the shaft. A fixing component for fixing the shaft is provided on the adjusting plate.

[0011] Furthermore, the fixing member includes an insertion hole on the outer periphery of the shaft, and an insertion rod with its end engaged with the insertion hole is slidably disposed on the adjusting plate. A limiting plate is fixed on the insertion rod, and a spring sleeved on the insertion rod is installed between the limiting plate and the adjusting plate.

[0012] Furthermore, two of the U-shaped plates are provided with outer rods, and the other two U-shaped plates are provided with inner rods, with the two inner rods respectively inserted into and cooperating with the two outer rods.

[0013] Furthermore, rubber pads are provided on opposite sides of both pressure plates.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] This embodiment provides a positioning device for a laser welding machine, mainly to solve the problem that existing positioning devices can only perform vertical positioning and cannot perform acute or obtuse angle positioning according to processing requirements. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0023] A positioning device for a laser welding machine, comprising:

[0024] A base 1 has two annular plates 2 on it. Two movable sleeves 3 are slidably fitted onto the annular plates 2. The movable sleeves 3 can slide along the circumference of the annular plates 2. A knob 4 is threaded through the movable sleeve 3, with its end abutting against the annular plate 2. After the movable sleeve 3 is slidably adjusted, the knob 4 is turned so that its end abuts against the annular plate 2. The pressing force is used to fix the movable sleeve 3 to the annular plate 2. A U-shaped plate 5 is provided on one side of the movable sleeve 3. A first positive and negative threaded rod 6 is rotatably threaded through the inner wall of the U-shaped plate 5 on opposite sides. Both ends of the first positive and negative threaded rod 6 are threaded with pressure plates 7. Preferably, one end of the pressure plate 7 overlaps with the inner wall of the U-shaped plate 5, so that the part to be welded is placed on the inner wall. The sheet material is placed inside the U-shaped plate 5 and between the two pressure plates 7. The first positive and negative screw 6 is turned, and under the action of the bidirectional screw, the two pressure plates 7 move synchronously in opposite directions. When the two pressure plates 7 approach each other, the sheet material is centered and clamped and fixed inside the U-shaped plate 5. When welding and positioning the sheet material, the two sheet materials are clamped and fixed by the corresponding two U-shaped plates 5 (using the two pressure plates 7 inside the U-shaped plate 5 for centering and pressing). Then, the movable sleeve 3 is slid and adjusted to adjust the angle of the two sheet materials. After the angle is adjusted, the knob 4 is turned to fix the movable sleeve 3, thereby fixing the angle of the two sheet materials to facilitate welding.

[0025] In this application, by setting two ring plates 2, the U-shaped plate 5 is slidably set on the ring plate 2 through the movable sleeve 3. The two plates are initially clamped and fixed by the corresponding two U-shaped plates 5. After the two plates are fixed, the movable sleeve 3 is slidably adjusted accordingly, and the plates are finally fixed by the knob 4. This allows the two plates to be positioned at right angles, acute angles and obtuse angles after they are fixed. The two plates can also be horizontally aligned to meet diverse welding positioning needs, thereby improving practicality.

[0026] like Figure 1 As shown, in this embodiment, a groove 9 is provided on the base 1. A second positive and negative screw 10 is rotatably inserted through the inner wall of the groove 9 on opposite sides. Two adjusting plates 11 are slidably inserted into the groove 9, and the two adjusting plates 11 are respectively threaded onto the two ends of the second positive and negative screw 10. Two ring plates 2 are respectively set on the two adjusting plates 11. When the second positive and negative screw 10 is twisted to rotate, under the bidirectional thread and the sliding limit of the groove 9, the two adjusting plates 11 can be driven to move synchronously in opposite directions. By setting the two ring plates 2 on the two adjusting plates 11 respectively, the distance between the two ring plates 2 can be adjusted, thus making it suitable for positioning plates of different sizes.

[0027] like Figure 2 and Figure 4 As shown, in this embodiment, a support plate 12 is connected to the inner wall of the ring plate 2. The support plate 12 is connected to the adjusting plate 11. A clearance groove 13 is provided through one side of the movable sleeve 3. The support plate 12 and the clearance groove 13 are inserted into each other. By setting the support plate 12 on the ring plate 2 and opening the clearance groove 13 on the movable sleeve 3 to be inserted into the support plate 12, even if the ring plate 2 is connected to the adjusting plate 11, the movable sleeve 3 can still slide 360 ​​degrees along the ring plate 2 to meet the positioning adjustment of large angle.

[0028] like Figure 4 As shown, in this embodiment, a shaft 14 is rotatably mounted on the adjusting plate 11, and the support plate 12 is fixedly connected to the shaft 14. A fixing member 15 for fixing the shaft 14 is provided on the adjusting plate 11. When some plates are welded at vertical, acute angle, and obtuse angles, double-sided welding is required. By rotatably mounting the shaft 14 on the adjusting plate 11 and fixing the support plate 12 to the shaft 14, the ring plate 2 can be rotated and adjusted so that the orientation of the plate can be adjusted without removing the plate, which is convenient for double-sided welding. After the angle is adjusted, the shaft 14 is fixed by the fixing member 15 so that the plate is in a stable state during welding, thereby improving practicality.

[0029] like Figure 4As shown, in this embodiment, the fixing member 15 includes insertion holes 1501 formed on the outer periphery of the shaft 14. Preferably, there are several insertion holes 1501 distributed in a ring along the outer surface of the shaft 14. An insertion rod 1502 with its end engaged with the insertion hole 1501 is slidably disposed on the adjusting plate 11. A limiting plate 1503 is fixed on the insertion rod 1502. A spring 1504 sleeved on the insertion rod 1502 is installed between the limiting plate 1503 and the adjusting plate 11. When it is necessary to release the fixing, the insertion rod 1502 is pulled. 02. Once disengaged from the insertion hole 1501, the adjusting ring plate 2 can be rotated freely. After the ring plate 2 is rotated and adjusted, the insertion rod 1502 is inserted into the corresponding insertion hole 1501, thereby fixing the shaft 14. By setting the limiting plate 1503 and the spring 1504, the elastic force of the spring 1504 makes the insertion rod 1502 more stable in the insertion hole 1501. The overall structure of the fixing part 15 allows for fixing or unfixing simply by pulling the insertion rod 1502, making the operation simple and convenient.

[0030] like Figure 1 As shown, in this embodiment, two U-shaped plates 5 are each provided with an outer rod 16, and two other U-shaped plates 5 are each provided with an inner rod 17. The two inner rods 17 are respectively inserted into and cooperate with the two outer rods 16. Preferably, as shown... Figure 1 As shown, the outer rod 16 and the inner rod 17 are connected to the two ring plates 2 and the corresponding U-shaped plates 5. The insertion and cooperation of the inner rod 17 and the outer rod 16 allows the corresponding U-shaped plates 5 on the two ring plates 2 to be slidably adjusted at the same time, so as to more conveniently clamp and fix the plate.

[0031] like Figure 3 As shown in this embodiment, rubber pads 8 are provided on opposite sides of the two pressure plates 7. By providing rubber pads 8 on the pressure plates 7, not only can the friction be increased, making the clamping of the plate more stable, but also the clamping marks caused by the rigid clamping of the plate can be avoided, thereby improving practicality.

[0032] like Figure 2 As shown, in this embodiment, a scale ring 18 is provided on the ring plate 2, and a pointer 19 is provided on the movable sleeve 3 to cooperate with the scale ring 18 for measurement. Preferably, the thickness of the scale ring 18 is less than the width of the clearance groove 13, so that the scale ring 18 will not affect the normal sliding of the movable sleeve 3. The pointer 19 is aligned with the movable sleeve 3 for positioning. Since the plate is aligned with the U-shaped plate 5 after it is fixed, and the U-shaped plate 5 is aligned with the movable sleeve 3, the plate is aligned with the pointer 19 after it is fixed. Through the measurement cooperation of the pointer 19 and the scale ring 18, the angle of the two adjacent plates can be more accurately controlled to ensure the positioning effect.

[0033] The working process of this utility model is as follows: When positioning the plate, first place both ends of the plate in the corresponding two U-shaped plates 5, and place the plate between the two pressure plates 7. Twist the first positive and negative screw 6 to rotate. Under the action of the bidirectional screw, the two pressure plates 7 move synchronously in opposite directions. When the two pressure plates 7 approach each other, the plate is centered and clamped and fixed in the U-shaped plates 5. After both plates are fixed, slide the movable sleeve 3 to adjust the angle of the two plates. After adjusting the angle, turn the knob 4 to fix the movable sleeve 3, thereby positioning the two plates. The sliding cooperation between the movable sleeve 3 and the ring plate 2 allows the two plates to be positioned at right angles, acute angles, and obtuse angles after they are fixed. The two plates can also be horizontally aligned to meet diverse welding positioning needs, thereby improving practicality.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
