The vibration of the round tube is to detect the welding strength of the round tube. The vibration is used to detect the welding stability of the round tube, thereby avoiding quality problems during subsequent reuse. In addition, the vibration makes the welding slag active, and the rotation of the vertical tube and the horizontal tube to guide the welding slag avoids the welding slag from blocking the weld and ensures the observation of the weld.

[0020] The present invention provides an auxiliary device for welding automobile parts, which has the following beneficial effects:

[0021] 1. The automobile parts welding auxiliary equipment, after the motor drives the belt to rotate rapidly in a certain direction in one direction, and then quickly drives the belt to rotate in the opposite direction. When the belt drives the round tube to rotate in one direction, the arc surface of the friction tooth contacts the round tube, and then quickly rotates in the opposite direction, the plane of the friction tooth contacts the round tube. A large number of small protrusions are set on the plane of the friction tooth, and the inertia in the rotation process is used to change the rotation direction at this time, and then the quality of welding is tested under the impact of inertia, which ensures the stability of welding and avoids the problem of subsequent welding failure.

In addition, the vibration makes the welding slag active, and the rotation of the vertical and horizontal tubes to guide the welding slag avoids the obstruction of the weld by the welding slag, ensuring the observation of the weld.

[0023] 3. The automobile parts welding auxiliary equipment, after the welding is completed, pushes the push rod to move in the annular sleeve, and then extends the horizontal tube into the round tube, which is easy to operate. The rotation diameter of the vertical tube is larger than the rotation diameter of the horizontal tube, so a pressure difference is generated during rotation. The gas in the round tube is squeezed under the pressure difference to move, so that the welding slag is moved, avoiding the welding slag from blocking the weld position, ensuring the guidance of the welding slag, avoiding the welding slag from clogging the weld, improving the observation of the weld, and ensuring the welding quality of the component.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] For example, see Figure 1-7 The present invention provides a technical solution: an auxiliary device for welding automobile parts, comprising a frame 1, a plate 2 is fixedly connected to the outer wall of the frame 1, a double-gun ring welding device 3 is fixedly connected to one side of the plate 2, a fixed caliper 4 is fixedly connected to the other side of the plate 2, a rotating roller 5 is rotatably connected to the outer wall of the fixed caliper 4, and a vibrating mechanism 7 is fixedly connected to the outer wall of the plate 2;

[0036] The vibration mechanism 7 comprises:

[0037] A transmission gear set 72, the transmission gear set 72 is fixedly connected to the outer wall of the plate 2;

[0038] A transmission shaft 71, the transmission shaft 71 is rotatably connected to a transmission gear set 72;

[0039] The limiting plate 74 is fixedly connected to the outer wall of the plate 2 .

[0040] An arc-shaped tooth 73 is provided between the limiting plate 74 and the plate 2 , and a second spring 76 is fixedly connected to the bottom of the arc-shaped tooth 73 . The arc-shaped tooth 73 and the second spring 76 are sleeved between the limiting plate 74 and the plate 2 .

[0041] The transmission gear set 72 is in active contact with the arc-shaped teeth 73 , the outer wall of the second spring 76 is fixedly connected with the second spring 76 , the second spring 76 is fixedly connected with the frame 1 , and the outer wall of the arc-shaped teeth 73 is fixedly connected with the arc-shaped rod 77 .

[0042] The outer wall of the frame 1 is fixedly connected with a buffer mechanism 6, and the buffer mechanism 6 includes a first bracket 61, and the first bracket 61 is fixedly connected to the outer wall of the frame 1. The outer wall of the first bracket 61 is fixedly connected with a motor 62. After the motor 62 drives the belt 63 to rotate rapidly in a certain direction in one direction, the belt 63 is then rapidly driven to rotate in the opposite direction. When the belt 63 drives the round tube to rotate in one direction, the arc surface of the friction tooth 67 contacts the round tube, and then when it rapidly rotates in the opposite direction, the plane of the friction tooth 67 contacts the round tube. A large number of small protrusions are arranged on the plane of the friction tooth 67, and the inertia during the rotation process is utilized. At this time, the rotation direction is changed, and then the quality of the welding is tested under the impact of inertia, which ensures the stability of the welding and avoids the problem of subsequent welding failure. The arc rod 77 drives the vibration of the round tube to improve the detection intensity of the round tube.

[0043] The outer wall of the motor 62 is rotatably connected to a rotating shaft 68 , and the outer wall of the rotating shaft 68 is sleeved with a belt 63 .

[0044] The outer wall of the belt 63 is provided with a placement hole 65 , and the inner wall of the placement hole 65 is rotatably connected with a bearing 64 .

[0045] The outer wall of the bearing 64 is fixedly connected with a friction tooth 67 , a first spring 66 is fixedly connected between the bearing 64 and the placement hole 65 , and the rotating shaft 68 is fixedly connected with the transmission shaft 71 .

[0046] When in use, the raw material round tube to be welded is placed at the bottom of the plate 2, and then the fixed caliper 4 is started to fix the round tube material, and the rotating roller 5 on the fixed caliper 4 squeezes the round tube, so that the round tube can rotate, and the double-gun ring welding device 3 is started to weld the round tube;

[0047] Combined with Figure 2 and 6 As shown, the motor 62 is powered on to start and drive the rotating shaft 68 to rotate. When the round tube is inserted into the bottom of the plate 2, the round tube is also inserted into the belt 63. The rotating shaft 68 drives the belt 63 to rotate during rotation, and then drives the rotation of the round tube. The round tube cooperates with the double-gun ring welding device 3 to perform welding during the rotation process.

[0048] After welding is completed;

[0049] Combined with Figure 7 As shown, a control program is set in the motor 62. After the motor 62 drives the belt 63 to rotate rapidly in a certain direction in one direction, the belt 63 is then rapidly driven to rotate in the opposite direction. When the belt 63 drives the round tube to rotate in one direction, the arc surface of the friction tooth 67 contacts the round tube. Then, when the belt 63 rapidly rotates in the opposite direction, the plane of the friction tooth 67 contacts the round tube. Many small protrusions are set on the plane of the friction tooth 67, so the welding of the round tube is detected.

[0050] Combined with Figure 4 As shown, the rotating shaft 68 will also drive the transmission shaft 71 to rotate during the rotation process. The rotation of the transmission shaft 71 starts the transmission gear set 72 to rotate. The arc teeth 73 and the second spring 76 are sleeved on the arc teeth 73 and fixed by the second spring 76 and the second bracket 75 at the bottom. Then, when the transmission gear set 72 rotates, it collides with the arc teeth 73. At this time, the arc rod 77 is attached to the round tube. Then, when the vibration of the arc teeth 73 is transmitted to the arc rod 77, the arc rod 77 collides with the round tube. The vibration of the round tube is used to detect the welding strength of the round tube.

[0051] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0052] The outer wall of the frame 1 is fixedly connected with a detection mechanism 8 , which includes a third bracket 81 . The third bracket 81 is fixedly connected to the outer wall of the frame 1 , and an annular sleeve 82 is fixedly connected to the outer wall of the third bracket 81 .

[0053] A push rod 89 is inserted into the inner wall of the annular sleeve 82 , a horizontal tube 84 is fixedly connected to the outer wall of the push rod 89 , three vertical tubes 83 are fixedly connected to the outer wall of the horizontal tube 84 , and the vertical tubes 83 are in communication with the interior of the horizontal tube 84 .

[0054] The outer wall of the cross tube 84 is fixedly connected to the limiting column 87. After welding is completed, the push rod 89 is pushed to move in the annular sleeve 82, and then the cross tube 84 is extended into the round tube for easy operation. The rotation diameter of the vertical tube 83 is larger than the rotation diameter of the cross tube 84, so a pressure difference is generated during rotation. The gas in the round tube is squeezed under the pressure difference to move, so that the welding slag is moved, and the welding slag is prevented from blocking the weld position, ensuring the guidance of the welding slag, avoiding the clogging of the weld by the welding slag, improving the observation of the weld, and ensuring the welding quality of the component. The outer wall of the limiting column 87 is sleeved with a limiting ring 86, and a third spring 88 is fixedly connected between the limiting ring 86 and the limiting column 87, and the outer wall of the limiting ring 86 is fixedly connected to a fixing block 85.

[0055] When in use, after welding is completed, the push rod 89 is pushed to move in the annular sleeve 82, and then the horizontal tube 84 is extended into the round tube, the two fixing blocks 85 are pulled, and then the fixing blocks 85 are pulled and squeezed onto the round tube under the elasticity of the third spring 88. Therefore, during the rotation of the round tube, the horizontal tube 84 and the vertical tube 83 will be driven to rotate. The rotation diameter of the vertical tube 83 is larger than the rotation diameter of the horizontal tube 84, so a pressure difference will be generated during rotation. Under the pressure difference, the gas in the round tube is squeezed to move, so that the welding slag is moved, and the welding slag is prevented from blocking the weld position.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
