Description

Technical Field

[0001] This utility model relates to the field of double-swing handheld welding guns, and more particularly to a double-swing handheld welding gun with protective function. Background Technology

[0002] In modern industrial production, welding is a crucial joining technology, and its importance is self-evident. As the manufacturing industry continues to demand higher welding quality, efficiency, and flexibility, various advanced welding equipment have emerged.

[0003] The double-swing handheld welding gun, a commonly used welding tool, utilizes front-focusing technology. It eliminates the need for an f-theta lens, using a motor to move the eyepiece back and forth along the laser beam's transmission direction. This real-time adjustment of the beam divergence angle compensates for the optical path difference between focal points outside the center of the laser beam, resulting in a flat focal plane. It can achieve a scanning range several times that of an f-theta lens while maintaining a near-diffraction-limited focused spot. This allows for more precise control of laser energy distribution during welding, improving welding accuracy and quality.

[0004] Existing double-swing handheld welding guns lack protective structures, and workers typically wear glasses to perform welding operations. However, glasses only protect the eyes and cannot prevent sparks and slag from flying during welding from injuring the operator's face, neck, or other parts of the body. Therefore, a double-swing handheld welding gun with protective functions is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a double-swing handheld welding gun with protective function, including a gun body 1, which serves as the main frame of the double-swing handheld welding gun. The gun body 1 integrates a double-swing drive mechanism, a key optical focusing system for front focusing design, and welding energy transmission channels such as laser beams or arc conduction paths. The front structure design of the gun body 1 must ensure that the focal position of the optical system is fixed in front of the workpiece, so as to facilitate precise control of the penetration depth. It is suitable for thin plates or high-precision welding scenarios. Slide rails 2 are fixedly installed on both the left and right sides of the front of the gun body 1. They are bolted to the outside of the gun body 1 and are used to install connecting blocks 3. Connecting blocks 3 are snapped onto the outside of the slide rails 2 to connect connecting seats 4 and slide rails 2. Connecting seats 4 are fixedly connected to the outside of the connecting blocks 3. Two sets of connecting seats 4 are provided, and the two sets of connecting seats 4 are used to support telescopic rods 5.

[0034] Reference Figures 2-4 A telescopic rod 5 is rotatably connected to the inner wall of the connecting seat 4. The length of the telescopic rod 5 can be adjusted manually to adjust the shielding component 6, improving the practicality of the device. The shielding component 6 is connected to the right side of the telescopic rod 5 via another set of connecting seats 4. The shielding component 6 is used to block sparks, slag, and strong light generated during welding, reducing injury to operators. The connecting block 3 includes a slider 31 that slides on the outside of the slide rail 2. The slider 31 slides on the slide rail 2, allowing the shielding component 6 to be installed on the gun body 1. The front side of the slider 31 is connected via… The mounting plate 32 is fixed with screws to secure the operating component 33 and the spring 34, and also facilitates maintenance. The operating component 33 is slidably connected to the lower front part of the slider 31 and the rear side of the mounting plate 32. Multiple sets of slots are opened on the outer side of the slide rail 2. The operating component 33 is inserted into the inner wall of the slot. By pressing the operating component 33, the operating component 33 is disengaged from the slot on the slide rail 2, releasing the limitation on the slider 31. The operating component 33 and the slider 31 are elastically connected by the spring 34. The elastic force of the spring 34 pushes the operating component 33 into the slot.

[0035] Reference Figures 1-3 The telescopic rod 5 includes a connecting rod a51 and a connecting rod b52. The connecting rod b52 is slidably connected to the inner wall of the connecting rod a51. By moving the connecting rods a51 and b52, the distance of the shielding member 6 can be adjusted to adapt to the protection requirements of different welding scenarios. The left side of the connecting rod a51 and the right side of the connecting rod b52 are both set as spherical. The spherical connection of the connecting rods a51 and b52 is rotatably connected to the inner wall of the connecting seat 4. By using the spherical connection of the connecting rods a51 and b52, the position of the shielding member 6 in three-dimensional space can be adjusted.

[0036] A set screw 53 is threaded to the rear side of the connecting rod a51. The front side of the set screw 53 abuts against the outside of the connecting rod b52. The set screw 53 is used to lock the connecting rod a51 and the connecting rod b52. A through groove is opened on the spherical side of the connecting seat 4 near the connecting rod a51 and the connecting rod b52. A bolt and nut are provided on the outside of the connecting seat 4. By rotating the bolt, the spherical pressing force of the connecting seat 4 on the connecting rod a51 and the connecting rod b52 can be adjusted, thereby preventing loosening.

[0037] Reference Figure 3 and Figure 5The shielding component 6 includes an outer frame 61, which is fixedly connected to the right side of a set of connecting seats 4 on the right side. A baffle 62 is horizontally inserted into the inner wall of the outer frame 61. The baffle is made of high-temperature resistant and anti-spatter material such as heat-resistant glass or a filter lens to block the sparks, slag and strong light generated during welding. An auxiliary plate 63 is inserted into the right side of the baffle 62 to fix the baffle 62. Spring pieces 64 are provided on the upper and lower sides of the right side of the outer frame 61. A snap-fit ​​groove 65 is opened on the side of the auxiliary plate 63 near the spring piece 64. The spring piece 64 snaps into the inner wall of the snap-fit ​​groove 65. One end of the spring piece 64 is fixedly connected to the inner wall of the outer frame 61, and the other end of the spring piece 64 is bent. The inner wall of the auxiliary plate 63 can be quickly disassembled by the snap-fit ​​cooperation between the bent part of the spring piece 64 and the snap-fit ​​groove 65.

[0038] Working principle: When in use, press the operating part 33, the spring 34 is compressed, and the slider 31 will slide on the slide rail 2, driving the connecting seat 4, telescopic rod 5 and blocking part 6 to move laterally. After reaching the target position, release the operating part 33, the spring 34 returns to its original position, and the operating part 33 is inserted into the slot to fix it, thereby locking the lateral position of the blocking part 6.

[0039] The connecting rods a51 and b52 of the telescopic rod 5 can slide relative to each other, adjusting the distance between the shielding component 6 and the welding point. After adjusting to the appropriate length, tighten the set screw 53 to press against the connecting rod b52, fixing the length of the telescopic rod 5. Since the ends of the connecting rods a51 and b52 are spherical, they can rotate within the connecting seat 4. By cooperating with the bolts and nuts on the outside of the connecting seat 4, the clamping force can be adjusted, allowing for fine-tuning of the angle of the shielding component 6 in three-dimensional space to adapt to the protection requirements of different welding scenarios.

[0040] The baffle 62 of the shielding component 6 is made of high-temperature resistant and anti-spatter materials such as heat-resistant glass or filter lenses, which can block the sparks, slag and strong light generated during welding, and protect the safety of the operators.

[0041] When the baffle 62 needs to be replaced, pull the auxiliary plate 63. The spring piece 64 inside the outer frame 61 deforms due to the force on the bent end and disengages from the snap-fit ​​groove 65 of the auxiliary plate 63. The auxiliary plate 63 and the baffle 62 can then be slid out from the inner wall of the outer frame 61 to complete the disassembly. After replacing the baffle 62, insert the auxiliary plate 63 into the outer frame 61. The bent end of the spring piece 64 automatically snaps into the snap-fit ​​groove 65 to achieve quick fixation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
