Description

Technical Field

[0001] The utility model belongs to the field of welding technology, and specifically relates to a stainless steel product welding device. Background Art

[0002] During the welding process of stainless steel products, it is very important to control the distance between the welding gun and the stainless steel product;

[0003] If the distance between the welding gun and the stainless steel product is too far, the arc may become unstable, resulting in the formation of pores, local overheating or insufficient heating of the weld. On the contrary, if the distance is too close, it may cause excessive spatter. At the same time, the stability of the welding arc can be ensured by controlling the distance between the welding gun and the stainless steel product. The stability of the arc has a direct impact on the welding quality. A stable arc helps to achieve uniform penetration and weld shape, and improves the welding quality.

[0004] For example, a Chinese patent with the authorization announcement number CN213702283U discloses a precise adjustment mechanism for a stainless steel welding pipe welding gun, which can be provided with a clamping block mechanism at the upper end of the fixing mechanism, so that when the clamp ring clamps the welding gun, the top support block will fit closely around the welding gun, so as to firmly fix the welding and stably control the distance between the welding gun and the stainless steel product;

[0005] However, in the prior art, when welding stainless steel products, a handheld welding gun is mostly used, and the operator holds the welding gun and moves it on the surface of the stainless steel product to complete the welding of the stainless steel product. The control of the distance between the handheld welding gun and the stainless steel product usually requires manual control by the operator. During the welding process, the distance between the welding gun head and the surface of the stainless steel product is not easy to control, and the distance is prone to change, which affects the quality of welding.

[0008] A stainless steel product welding device comprises a welding gun body, a welding gun tube is installed at one end of the welding gun body, a welding gun head is fixedly connected to the end of the welding gun tube away from the welding gun body, an auxiliary positioning piece is slidably connected to the outer side of the welding gun tube, and an adjusting piece connected to the auxiliary positioning piece is assembled on the welding gun body, and the adjusting piece can adjust the distance between the positioning part and the welding gun head.

[0009] Furthermore, the adjusting member comprises a first screw rod rotatably connected to the welding gun body, and the first screw rod is threadably connected to the auxiliary positioning member.

[0010] Furthermore, the auxiliary positioning member includes a slide frame slidably connected to the outside of the welding gun tube, the slide frame is threadedly connected to the first screw rod, auxiliary arms are arranged on both sides of the slide frame, and the slide frame and the two auxiliary arms are arranged in a U shape.

[0011] Furthermore, the auxiliary arm includes a sleeve installed on one side of the slide, the internal thread of the sleeve is connected to a second screw rod, and one end of the second screw rod extends to the outside of the sleeve.

[0012] Furthermore, a rotating rod fixedly connected to the sleeve is rotatably connected on one side of the slide, a turbine is fixedly connected to the outer side of the rotating rod, a worm gear is rotatably connected on one side of the slide and located on one side of the turbine, and the worm gear is meshingly connected to the turbine.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1As shown, a stainless steel product welding device includes a welding gun body 1, a welding gun tube 2 is installed at one end of the welding gun body 1, and a welding gun head 3 is fixedly connected to the end of the welding gun tube 2 away from the welding gun body 1. When welding the stainless steel product, the welding gun head 3 is placed on the surface of the stainless steel product, and then the welding gun body 1 is started to weld the stainless steel product.

[0023] In order to control the quality of the weld, an auxiliary positioning piece 4 is slidably connected to the outer side of the welding gun tube 2, and an adjusting piece connected to the auxiliary positioning piece 4 is assembled on the welding gun body 1. The adjusting piece is used to drive the auxiliary positioning piece 4 to move on the outer side of the welding gun tube 2. The end of the auxiliary positioning piece 4 away from the welding gun body 1 is a positioning part. At this time, the adjusting piece can drive the auxiliary positioning piece 4 to slide and adjust the distance between the positioning part and the welding gun head 3. When welding stainless steel products, the positioning part of the auxiliary positioning piece 4 is allowed to abut against the surface of the stainless steel product, so as to control the distance between the welding gun head 3 and the surface of the stainless steel product, thereby better controlling the quality of welding.

[0024] Among them, Figure 1-2 As shown, the adjusting member includes a first screw rod 5 rotatably connected to the welding gun body 1, and the first screw rod 5 is threadedly connected to the auxiliary positioning member 4. When the first screw rod 5 rotates, the auxiliary positioning member 4 can be driven to slide on the outside of the welding gun tube 2, and after the movement is completed, the position of the auxiliary positioning member 4 can be locked by the thread, and the stability is relatively high.

[0025] Meanwhile, the adjusting member may also be an electric push rod fixedly connected to the outside of the welding gun body 1 and connected to the auxiliary positioning member 4 , and the auxiliary positioning member 4 can be driven to move outside the welding gun tube 2 by starting the electric push rod.

[0026] like Figure 1-2 As shown, the auxiliary positioning member 4 includes a slide 6 slidably connected to the outside of the welding gun tube 2, the slide 6 and the first screw 5 are threadedly connected, auxiliary arms are arranged on both sides of the slide 6, and the slide 6 and the two auxiliary arms are arranged in a U shape. At this time, the two auxiliary arms and the stainless steel tube are abutted against each other, so that the welding gun head 3 can be stably driven to move along the axis of the stainless steel tube on the outside of the stainless steel tube.

[0027] Here, if Figure 2 and Figure 4 As shown, the auxiliary arm includes a sleeve 7 installed on one side of the slide 6, and the internal thread of the sleeve 7 is connected to the second screw 8, one end of the second screw 8 extends to the outside of the sleeve 7, and the end of the second screw 8 extending to the outside of the sleeve 7 is a positioning portion. At this time, by rotating the second screw 8 and adjusting the length of the second screw 8 extending out of the sleeve 7, the distance between the positioning portion and the slide 6 can be adjusted. By adjusting the distance between the two positioning portions and the slide 6 to different lengths, the welding gun head 3 can be placed at different angles in the X-axis direction, and stainless steel products can be welded from different angles.

[0028] Moreover, one end of the second screw 8 extending to the outside of the sleeve 7 is fixedly connected to a ball seat 9, a spherical cavity is opened inside the ball seat 9, a spherical ball 10 is rotatably connected inside the spherical cavity, and an opening with a diameter smaller than the diameter of the spherical ball 10 is opened at one end of the spherical cavity away from the second screw 8, and the edge of the spherical ball 10 extends to the outside of the ball seat 9 through the opening. At this time, when the stainless steel product is welded, the spherical ball 10 moves on the surface of the stainless steel product, and the rotation of the spherical ball 10 can reduce the wear on the surface of the steel product.

[0029] like Figure 2-3 As shown, in order to place the welding gun head 3 at different angles in the Y-axis direction and weld the stainless steel products from more angles, a rotating rod 11 fixedly connected to the sleeve 7 is rotatably connected to one side of the slide 6, and a turbine 13 is fixedly connected to the outer side of the rotating rod 11. A vortex rod 12 is rotatably connected to one side of the slide 6 and located on one side of the turbine 13. The vortex rod 12 and the turbine 13 are meshingly connected. When the vortex rod 12 is rotated, the turbine 13 can be driven to rotate, so that the turbine 13 provides rotational kinetic energy to the rotating rod 11 and the sleeve 7, and the angle of the sleeve 7 can be adjusted. After the adjustment is completed, the angle of the sleeve 7 can be locked by the vortex rod 12 and the turbine 13.

[0030] The working principle of the utility model is as follows: when welding a steel product, a spherical ball 10 is placed on the surface of the steel product, and then the first screw 5 is rotated to drive the slide 6 to move, thereby controlling the distance between the welding gun head 3 and the steel product;

[0031] After the spacing adjustment is completed, the welding gun body 1 is started, and the stainless steel product is welded through the welding gun head 3. During the welding process, the welding gun head 3 and the slide 6 are driven to move on the surface of the steel product. The spacing between the welding gun head 3 and the surface of the stainless steel product can be stably controlled during the manual welding of stainless steel products, thereby better controlling the quality of welding.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
