[0002] Nowadays, there are many types and styles of welding devices. The main types of welding equipment are electric welders, flame welding equipment and other welding equipment. According to the usage scenarios, there are also fully automatic, semi-automatic and manual welders. The most commonly used is the handheld electric welder, which is not only flexible to use but also low in cost. However, high temperature, strong light radiation and metal vapor will be generated during the welding process, which will cause certain damage to the human body. Therefore, traditional electric welders need to wear or hold heavy welding helmets when in use, which not only affects the operation of the staff and reduces the sensitivity of the operation, but also makes the blind area of the staff larger, restricting the staff's ability to move in emergencies, and the welding helmet itself can only protect the head, and the sparks generated during welding may burn the skin through the collar and cuffs. In addition, the traditional operation method requires the staff to hold the welding rod with their left hand, which is close to the high-temperature welding point, and there are certain safety hazards. Therefore, we propose a welding device with protective function to solve the above problems. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-Figure 4 As shown, a welding device with a protective function comprises an electric welding carriage 1, a protective structure 4 and a wire feeder 5, wherein a detachable electric welding machine 2 is fixedly mounted on the upper end of the electric welding carriage 1, a detachable oxygen cylinder stand 3 is fixedly mounted on the rear end of the electric welding carriage 1, the protective structure 4 comprises a protective cover 41, a movable base 42 is arranged at the lower end of the protective cover 41, the protective structure 4 further comprises a welding gun 43, the welding gun 43 and the electric welding machine 2 are linearly connected, a universal ball 44 is fixedly sleeved near the middle of the welding gun 43, a ball sleeve 45 is arranged at the middle position of the protective cover 41 near the upper side, the universal ball 44 is rotatably mounted inside the ball sleeve 45, a radiation-proof glass 46 is arranged at the front end of the protective cover 41 near the upper side, and a handle assembly 47 is fixedly mounted at the rear end of the protective cover 41 near the lower side;
[0020] By placing tools such as the electric welder 2 and the oxygen cylinder rack 3 on the designed electric welding trolley 1, compared with the traditional shape, it is not only more convenient to move, but also more standardized when placed, which can avoid damage or gas leakage caused by accidental contact to a certain extent. When in use, due to the design of the mobile base 42, the staff can drive the protective cover 41 to move by holding the handle assembly 47 with a little force, so that it is convenient to move to the welding point and then use the protective cover 41 to shield the whole body, avoiding sparks splashing into the gaps such as cuffs and collars during welding to burn the skin, which is safer. The radiation-proof glass 46 can ensure that the staff's line of sight is not blocked, and at the same time filter the influence of strong light radiation, and the blind spot of the field of vision is smaller, and the staff can move more freely.
[0021] The upper end of the wire feeder 5 is fixedly connected with a wire drawing frame 501 near the front side, and a servo motor 502 is fixedly installed in the middle of the left end of the wire drawing frame 501. The right end output end of the servo motor 502 passes through the wire drawing frame 501 and is fixedly sleeved with a main gear 503. The front and rear ends of the main gear 503 are meshed with a lower gear 504. The right side of the lower gear 504 is provided with a positioning member 505. The lower gear 504 is rotatably installed on the right end of the wire drawing frame 501 through the positioning member 505. The upper end of the wire drawing frame 501 is rotatably installed with a flip member 506 near the front and rear sides, and an upper gear 507 is rotatably installed inside the flip member 506. The upper gear 507 is meshed with the lower gear 504 respectively, and the right ends of the upper gear 507 and the lower gear 504 are fixedly connected with a walking coil 508.
[0022] By turning on the servo motor 502 and rotating its output end in a clockwise direction, the main gear 503 can be driven to rotate synchronously. The clockwise rotation of the main gear 503 can drive the two sets of lower gears 504 to rotate in a counterclockwise direction. The rotation of the lower gears 504 can drive the upper gears 507 to rotate in the opposite direction. After the head end of the welding wire wound on the wire coil assembly 509 passes through the wire passer 510, the anti-winding piece 511 and the wire outlet gun 512, the rotation of the lower gear 504 and the upper gear 507 can drive the wire coil 508 to rotate, so that the friction between the wire coil 508 and the welding wire during rotation and the guidance of the traction direction can achieve the purpose of wire pulling.
[0023] The front and rear ends of the wire drawing frame 501 are both provided with wire passers 510. The right end of the wire drawing frame 501 is fixedly installed with an anti-entanglement piece 511 in the middle of the upper side of the main gear 503. The wire feeder 5 includes a wire outlet gun 512 fixedly connected to the welding gun 43. The upper end of the wire feeder 5 is fixedly installed with a wire coil assembly 509 at the rear side of the wire drawing frame 501. The welding wire on the wire coil assembly 509 passes through the wire passer 510, the wire coil 508, the anti-entanglement piece 511 and the wire outlet gun 512 in sequence.
[0024] The anti-entanglement piece 511 is used to ensure the horizontal movement of the welding wire. Finally, the strength and toughness of the welding wire itself can be used to make it extend out of the wire outlet gun 512, and it is controlled together with the control of the welding gun 43. The wire feeder 5 is used to avoid the operator's need to hold the welding wire with his left hand during welding. This not only avoids the influence of high temperature and high heat at the welding point, which is safer, but also frees up the work of the left hand, allowing the operator to respond more coordinatedly, thereby improving the user experience.
[0025] Working principle:
[0026] By placing tools such as an electric welder 2 and an oxygen cylinder stand 3 on a designed electric welding trolley 1, the welding device is not only more convenient to move, but also more standardized in placement compared to the traditional shape, and can avoid damage or gas leakage caused by accidental contact to a certain extent. When in use, due to the design of the mobile base 42, the staff can drive the protective cover 41 to move by holding the handle assembly 47 with a little force, so that it is convenient to move to the welding point and then use the protective cover 41 to shield the whole body, so as to avoid sparks splashing into the gaps such as cuffs and collars during welding and burn the skin, which is safer. The radiation-proof glass 46 can ensure that the staff's vision is not blocked, and at the same time filter the influence of strong light radiation, and the blind spot of the field of vision is smaller, so that the staff can move more freely. By moving the protective cover 41 and coordinating the direction adjustment between the universal ball 44 and the ball sleeve 45, the welding gun 43 can be controlled to weld different welding points. Furthermore, by turning on the servo motor 502 to rotate its output end clockwise, the main gear 503 can be driven to rotate synchronously. , the clockwise rotation of the main gear 503 can drive the two sets of lower gears 504 to rotate counterclockwise, and the rotation of the lower gear 504 can drive the upper gear 507 to rotate in the opposite direction respectively. After the head end of the welding wire wound on the wire coil assembly 509 passes through the wire passer 510, the anti-winding piece 511 and the wire outlet gun 512, the rotation of the lower gear 504 and the upper gear 507 can drive the wire loop 508 to rotate, so that the friction between the wire loop 508 and the welding wire during rotation, combined with the guidance of the traction direction, plays the purpose of pulling the wire, and the anti-winding piece 511 is used to ensure the movement of the welding wire in the horizontal direction. Finally, the strength and toughness of the welding wire itself can be used to make it extend from the wire outlet gun 512, and it is controlled together in the control of the welding gun 43. The wire feeder 5 avoids the operation mode of the staff holding the welding wire with the left hand during welding, which not only avoids the influence of high temperature and high heat at the welding point, but also makes it safer, and frees the work of the left hand, so that the staff can respond more coordinatedly, thereby improving the user experience.
