Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber laser cutting machines, in particular to an induction laser cutting head for an optical fiber laser cutting machine. Background Art

[0002] Fiber laser cutting machine is a highly efficient and precise cutting device, widely used in cutting metal, non-metal and other materials. The performance of the laser cutting head directly affects the cutting quality and efficiency.

[0003] In the prior art, after searching, it was found that a Chinese patent disclosed a new type of inductive laser cutting head for a fiber laser cutting machine, and its application number is 201520969579.2. This patent mainly installs a distance sensor on the side of the cutting head of the fiber laser cutting machine. The distance sensor is connected to the computer control system. The distance sensor is arranged in a slot on the side of the cutting head. The slot is fixed to the side of the cutting head by screws. A through hole is provided at the front end of the slot. The set screw passes through the through hole to fasten the distance sensor. A straight notch is provided on the upper part of the distance sensor. The bolt passes through the straight notch to fix the distance sensor to the side of the cutting head. Although the above-mentioned utility model can automatically raise or lower according to the height of the plate, the distance between the cutting head and the plate is kept constant, thereby achieving a better cutting effect. At the same time, fixing the distance sensor in the slot realizes the simple installation of the distance sensor. The height of the sensor can be adjusted more conveniently through the screws on the side and front end of the distance sensor, and the sensor can be prevented from accidentally falling. However, when installing the distance sensor, the above-mentioned cutting head needs to install multiple screws on both sides and the top to fix the distance sensor, which is cumbersome to install.

Therefore, those skilled in the art provide an inductive laser cutting head for a fiber laser cutting machine to solve the problems raised in the above-mentioned background technology.

[0022] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figure 1 and Figure 3 , an embodiment of the utility model is an inductive laser cutting head for a fiber laser cutting machine, which includes a cutting head 1 and a distance sensor 5 arranged on the outside of the cutting head 1. Two guide rails 2 with a convex structure are fixedly connected to the outside of the cutting head 1 in a symmetrical manner, and two slide rails 3 that are compatible with the guide rails 2 are slidably connected to the outside of the two guide rails 2. A connecting plate 6 is connected between each two opposite slide rails 3 by a fixed connection. Two mounting plates 4 with a C-shaped structure are fixedly connected between the two connecting plates 6 in a symmetrical manner, and the distance sensor 5 is inserted between the two mounting plates 4. A positioning assembly is provided on one side of one of the mounting plates 4 and located in front of the distance sensor 5. The positioning assembly is used to prevent the distance sensor 5 from sliding off between the mounting plates 4. An adjustment assembly is provided between the cutting head 1 and the distance sensor 5. The adjustment assembly is used not only to adjust the height of the distance sensor 5, but also to prevent the mounting plate 4 from sliding downward;

[0024] Specifically, the sliding cooperation of the slide rails 3 and the guide rails 2 ensures the stability of the front-to-back position of the mounting plate 4 on the connecting plate 6. The provided adjustment assembly is easy to operate and can realize the positioning operation of the mounting plate 4. The adjustment assembly can also facilitate the adjustment of the height of the mounting plate 4, thereby making the height adjustment operation of the distance sensor 5 simpler and more efficient. When the distance sensor 5 is inserted between the two C-shaped mounting plates 4, the distance sensor 5 can be limited on both sides, above and below, and at the rear. At the same time, a positioning assembly is provided on the distance sensor 5 to prevent the distance sensor 5 from sliding off the inside of the mounting plate 4. The positioning assembly is easy to operate, making the installation of the distance sensor 5 convenient and highly practical.

[0025] Reference Figure 1 、 Figure 3 and Figure 4 The positioning assembly includes a groove 11 provided inside the mounting plate 4, a baffle 13 movably connected to the inside of the groove 11, three connecting rods 12 equidistantly arranged and slidably connected to the inside of the mounting plate 4, three fixing plates 14 fixedly connected to the outside of the corresponding connecting rods 12, three springs 15 sleeved on the outside of the corresponding connecting rods 12, and an operating plate 16 provided on the outside of the mounting plate 4 and located on one side of the groove 11. One end of the three connecting rods 12 is fixedly connected to the baffle 13, and the other end extends to the outside of the mounting plate 4 and is fixedly connected to the operating plate 16. The spring 15 is located on the side of the fixing plate 14 away from the baffle 13. The baffle 13 extends to the outside of the groove 11 and fits in with the front side of the distance sensor 5.

[0026] Specifically, when the distance sensor 5 is installed inside the mounting plate 4, pulling the operating plate 16 to the left causes the connecting rod 12 to move to the left. The moving connecting rod 12 simultaneously drives the baffle 13 to move to the left into the groove 11, and the distance sensor 5 can be inserted between the mounting plates 4. Releasing the operating plate 16 pushes the fixing plate 14 to the right under the action of the spring 15. The moving fixing plate 14 causes the connecting rod 12 to move to the right, causing the baffle 13 to move to the outside of the groove 11. The baffle 13, which is in contact with the outside of the distance sensor 5, acts as a limiter to prevent the distance sensor 5 from moving or slipping, ensuring the stability of the distance sensor 5 and facilitating operation, making the installation and removal of the distance sensor 5 more convenient.

[0027] Reference Figure 1 、 Figure 2 and Figure 3 The adjustment assembly includes a second die plate 9, a screw 7, and a first die plate 8. The second die plate 9 is fixedly connected to the outside of the cutting head 1. The first die plate 8 is rotatably connected to one end of the screw 7. The screw 7 is internally threadedly connected to the connecting plate 6. The screw 7 is located above the distance sensor 5. The first die plate 8 and the second die plate 9 are connected in a cooperative manner. The adjustment assembly also includes a knob 10, which is fixedly connected to the other end of the screw 7 to facilitate the user to operate the screw 7.

[0028] Specifically, the first threaded plate 8 is tightly coupled to the second threaded plate 9 under the positioning action of the screw 7, thereby fixing the position of the mounting plate 4 to ensure stable operation of the distance sensor 5. When the height of the distance sensor 5 needs to be adjusted, the knob 10 is turned to drive the screw 7 to rotate so that the first threaded plate 8 moves and separates from the second threaded plate 9, thereby unlocking the mounting plate 4, allowing the height of the distance sensor 5 to be adjusted up and down. This is simple to operate and flexible to use.

[0029] Reference Figure 1 and Figure 3 A scale line 17 is provided on the outer surface of the cutting head 1 and on one side of the distance sensor 5 so that the user can accurately control the moving distance of the distance sensor 5 .

[0030] Reference Figure 3 and Figure 4 The side of the baffle 13 opposite to the distance sensor 5 is set as a slope structure. When the distance sensor 5 moves toward the inner side of the mounting plate 4 and is inserted between the mounting plates 4, the set slope facilitates the moving distance sensor 5 to push the baffle 13 to move into the inside of the groove 11, making it convenient for the distance sensor 5 to be inserted into the inner side of the mounting plate 4.

[0031] Working principle: the first tooth plate 8 is tightly connected with the second tooth plate 9 under the positioning action of the screw rod 7, so that the position of the mounting plate 4 can be fixed. When the distance sensor 5 is inserted between the two C-shaped mounting plates 4, the inclined surface provided facilitates the movable distance sensor 5 to push the baffle 13 to move to the inside of the groove 11, which is convenient for the distance sensor 5 to be inserted into the inner side of the mounting plate 4. The operating plate 16 pushes the fixing plate 14 to move to the right under the action of the spring 15. The moving fixing plate 14 can make the connecting rod 12 move to the right so that the baffle 13 moves to the outside of the groove 11. The baffle 13 that fits the outside of the distance sensor 5 can play a limiting role to prevent the distance sensor 5 from moving or slipping, thereby ensuring the stability of the distance sensor 5 and making the installation of the distance sensor 5 convenient.

[0032] When the height of the distance sensor 5 needs to be adjusted, the knob 10 is turned to drive the screw 7 to rotate so that the first tooth plate 8 moves and separates from the second tooth plate 9, and the mounting plate 4 can be unlocked to facilitate the up and down movement to adjust the height of the distance sensor 5. The operation is simple and flexible to use.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
