Description

Technical Field

[0001] This utility model relates to the field of metal cutting, and in particular to a structure for a through-weld hole cutting gun. Background Technology

[0002] The design of weld holes facilitates the smooth release of gases generated during welding, thereby ensuring weld quality. Furthermore, weld holes reduce stress concentration at weld junctions, preventing structural damage caused by stress concentration. Therefore, in the cutting and processing of metal components, weld holes are typically cut using a cutting gun. For example, a weld hole cutting gun disclosed on the China Patent Network (publication number CN220050366U) is used. This type of weld hole cutting gun, equipped with a cutting line positioning device, allows for pre-loosening of bolts according to the required weld hole radius, adjusting the distance between the positioning rod and the cutting nozzle, and then tightening the bolts. During cutting, the suspended end of the positioning rod rests against the cutting surface of the metal sheet, the gas source is turned on, and the cutting nozzle is gradually rotated around the contact point between the positioning rod and the metal sheet to complete the R-angle cutting of the weld hole. This eliminates the need for scribing, improving the cutting accuracy of the weld hole.

[0003] However, the aforementioned patented and existing weld hole cutting guns have some shortcomings: the existing method of adjusting the cutting radius using bolts has poor adjustment stability, and during use, the bolts are prone to loosening, causing deviation and displacement of the cutting gun, resulting in inconsistent cutting radii and poor cutting quality. Therefore, those skilled in the art have provided a weld hole cutting gun structure to solve the problems mentioned in the background. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a weld hole cutting gun structure that solves the problem mentioned in the background art, where the existing weld hole cutting guns have poor adjustment stability and are prone to cutting deviations.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a through-weld hole cutting gun structure, including vertically opposite support rods and an electromagnetic magnet, wherein the support rods and the electromagnetic magnets are connected by a rotating seat;

[0006] The arm of the supporting pole is equipped with a cutting and positioning mechanism, and a cutting gun head is installed through the support of the cutting and positioning mechanism.

[0007] The cutting alignment mechanism includes an adjusting guide rail installed on the upper end of the support pole arm. The slide rail of the adjusting guide rail is internally connected to an alignment screw, and an alignment slide is provided on the outer side of the shaft of the alignment screw, which guides the adjusting guide rail. A support seat for supporting the cutting gun head is provided on the front side of the frame of the alignment slide.

[0008] As a further technical solution of this utility model: a calibration knob is installed at one end of the shaft of the calibration lead screw.

[0009] As a further technical solution of this utility model: the upper end of the slide rail of the adjustment guide is provided with a scale, and the back plate of the calibration slide is provided with a pointer that is opposite to the indication of the scale.

[0010] As a further technical solution of this utility model: the supporting pole is a hollow pole structure, and a conduit connected to an electromagnet is installed through the hollow cavity of the supporting pole.

[0011] As a further technical solution of this utility model: the supporting upright and the rotating seat are rotatably connected to each other, and the electromagnetic magnet is fixedly connected to the rotating seat.

[0012] This utility model provides a through-weld hole cutting gun structure, which has the following advantages compared with the prior art:

[0013] 1. When using the weld hole cutting gun designed in this way, the operator can adjust the distance between the cutting gun head and the support column by simply turning the knob, based on the pre-adjustment of the cutting alignment mechanism driven by the screw. This allows for adjustment and alignment of the cutting radius of the cutting gun head. The overall operation is simple and convenient, while also providing better adjustment stability and reducing the likelihood of loosening or deviation.

[0014] 2. In the welding hole cutting gun of this design, during the cutting process, the combination of the support rod and the electromagnetic magnet serves as the cutting center of the welding hole. Then, by energizing the electromagnetic magnet, the electromagnetic magnet and the metal plate are magnetically positioned to locate the cutting center. This allows the cutting gun head to rotate smoothly in the circumferential direction during arc cutting, improving the cutting quality. After cutting, it is only necessary to disconnect the power to the electromagnetic magnet. Attached Figure Description

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a through-weld hole cutting gun structure: a through-weld hole cutting gun structure, including a vertically opposite support rod 1 and an electromagnetic magnet 3, and the support rod 1 and the electromagnetic magnet 3 are connected by a rotating seat 2. The support rod 1 is a hollow rod structure, and a conduit 9 connected to the electromagnetic magnet 3 is installed through the hollow cavity of the support rod 1. The support rod 1 and the rotating seat 2 are rotatably connected to each other, and the electromagnetic magnet 3 and the rotating seat 2 are fixedly connected to each other. By energizing the electromagnetic magnet 3, it maintains its magnetic attraction and is fixed to the metal material. By using the electromagnetic magnet 3 to coincide with the fixed point of the cutting circle, and then based on the rotational support of the support rod 1, when performing arc cutting, the combination of the cutting gun head 8 and the support rod 1 rotates and cuts along the rotating seat 2, which has better cutting stability and more efficient cutting quality.

[0022] The arm of the support pole 1 is equipped with a cutting alignment mechanism, and a cutting head 8 is installed through the support of the cutting alignment mechanism. The cutting alignment mechanism includes an adjusting guide rail 4 installed at the upper end of the arm of the support pole 1. An alignment screw 5 is connected inside the slide rail of the adjusting guide rail 4, and an alignment slide 6 is provided on the outer side of the shaft of the alignment screw 5, which is guided by the adjusting guide rail 4. A support seat 7 for supporting the cutting head 8 is provided on the front side of the frame of the alignment slide 6. An alignment knob 10 is installed at one end of the shaft of the alignment screw 5. By rotating the alignment knob 10, the alignment screw 5 is driven to rotate. During the rotation of the alignment screw 5, the alignment slide 6 is pushed to slide horizontally along the slide rail of the adjusting guide rail 4, and then the combination of the support seat 7 and the cutting head 8 is pushed to slide horizontally, thereby adjusting and aligning the distance between the cutting head 8 and the support pole 1, and then adjusting and aligning the cutting radius of the cutting arc of the cutting head 8. The adjustment is simple and convenient, and the stability after adjustment is better.

[0023] The upper end of the slide rail of the adjusting guide rail 4 is provided with a scale 12, and the back plate of the calibration slide 6 is provided with a pointer 11 that is opposite to the indication of the scale 12. When the calibration slide 6 slides, it drives the pointer 11 to slide horizontally in sync. The pointer 11 corresponds to the mark of the scale 12 and serves as the cutting adjustment scale line of the cutting gun head 8.

[0024] The working principle of this utility model is as follows: When using a cutting gun to cut through weld holes, the cutting position of the cutting gun head 8 is pre-adjusted according to the cutting radius of the weld hole. Then, taking the combination of the support rod 1 and the electromagnet 3 as the cutting center, the positioning knob 10 is rotated to drive the positioning screw 5 to rotate, which pushes the positioning slide 6 to slide horizontally along the slide rail of the adjustment guide rail 4. Then, the combination of the support seat 7 and the cutting gun head 8 is pushed to slide horizontally to adjust and calibrate the distance between the cutting gun head 8 and the support rod 1, and then the cutting radius of the cutting arc of the cutting gun head 8 is adjusted and calibrated.

[0025] After adjusting and calibrating the cutting radius of the cutting gun head 8, the electromagnetic magnet 3 is placed at the center of the weld hole to be cut. By energizing the electromagnetic magnet 3, it maintains its magnetic attraction and is fixed to the metal material. When the metal material to be cut cannot be magnetically attracted, magnetic metal material can be added to its back plate to magnetically fix the electromagnetic magnet 3. Then, by aligning the electromagnetic magnet 3 with the center of the cutting circle, the combination of the cutting gun head 8 and the support rod 1 rotates along the rotating seat 2 directly above the electromagnetic magnet 3 during arc cutting. This results in better cutting stability and higher cutting quality when cutting weld holes in metal materials.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
