Description

Technical Field

[0001] The invention relates to the technical field of automatic welding, in particular to a steel plate welding device for mechanical manufacturing. Background Art

[0002] In the modern industrial field, steel plate welding is of vital importance. Traditional welding mostly relies on manual experience to control the current and the speed of the wire rod, which is prone to defects such as uneven welds and slag inclusions, and the efficiency and quality are limited. With the development of science and technology, automated welding equipment has emerged. With the help of precision sensors and CNC systems, it can accurately control parameters and perform welding stably. In addition, new welding materials are constantly emerging, which are suitable for a variety of steel plates. They are excellent in strength and corrosion resistance, and they work together to improve the welding level and meet complex manufacturing needs.

[0003] A patent application with application number CN202323586662.5 discloses a steel plate welding device for mechanical manufacturing, which relates to the field of mechanical manufacturing technology. It includes a welding table and a flip plate. The tops of the welding table and the flip plate are both provided with mounting grooves. Steel plate positioning mechanisms are provided in the two mounting grooves, and an electric flipping mechanism is provided on the welding table. Two columns are symmetrically welded on the top outer wall of the welding table.

[0004] In summary, when carrying out steel plate welding operations, the steel plate welding needs to be carried out on two sides in sequence. After completing the welding operation on one side of the steel plate, the steel plate needs to be turned over and fixed for a second time. When turning over the steel plate that has only been welded on one side, there is a risk of cracking of the weld in the secondary fixing link, which affects the welding yield and efficiency of the steel plate.

[0033] 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.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example 1: See Figure 1-Figure 3The present invention provides a technical solution: a steel plate welding device for mechanical manufacturing, comprising a first support frame 1, a support foot 2 is fixedly connected to the bottom outer wall of the first support frame 1, a first fixing frame 3 is fixedly connected to the inner wall of the first support frame 1, a groove 4 is provided on the inner wall of the first fixing frame 3, a second support frame 5 is fixedly connected to the top outer wall of the first support frame 1, a fixing shaft 6 is fixedly connected to the inner wall of the second support frame 5, a first driving motor 7 is fixedly connected to the outer wall of the second support frame 5, an output end of the first driving motor 7 passes through the second support frame 5 and is fixedly connected to a rotating shaft 8, a first sliding frame 9 is provided at the output end of the first driving motor 7, a welding device 11 is provided at the bottom of the first sliding frame 9, and also includes:

[0036] The adjusting mechanism 12 includes a second sliding frame 121 arranged inside the first fixed frame 3, an auxiliary motor 122 is fixedly connected to the outer wall of the second sliding frame 121, and a driving wheel 123 is fixedly connected to the output end of the auxiliary motor 122. The outer surface of the driving wheel 123 is rollingly connected to the inner wall of the groove 4, and a second hydraulic rod 126 is fixedly connected to the inner wall of the second sliding frame 121 away from the auxiliary motor 122, and an auxiliary wheel 128 is fixedly connected to the output end of the second hydraulic rod 126. A clamping mechanism 13 is arranged on the side of the second sliding frame 121 close to the second hydraulic rod 126. The clamping mechanism 13 includes a rotating frame 131 rotatably connected to the second sliding frame 121, and a through hole 132 is opened on the outer surface of the rotating frame 131. The second hydraulic rod 126 is slidably connected to the inner wall of the through hole 132 by means of the auxiliary wheel 128 on the outer wall of the connecting block 127. When the steel plate welding operation is carried out, the second hydraulic rod 126 operates to The connecting block 127 applies a pulling force, and the connecting block 127 moves under the force, driving the auxiliary wheel 128 connected thereto to slide on the inner wall of the through hole 132 opened in the rotating frame 131. Due to the matching relationship between the auxiliary wheel 128 and the through hole 132, as the auxiliary wheel 128 slides, the rotating frame 131 will flip toward one side of the steel plate at a specific fulcrum until it is flipped into place, and the clamping mechanism 13 is in close contact with the steel plate and applies force to achieve clamping and fixing of the steel plate, laying a solid foundation for the welding operation. When the steel plate is to be turned over, the auxiliary motor 122 is started to drive the driving wheel 123 connected thereto to roll on the inner wall of the groove 4, and the second sliding frame 121 is driven to flip over the inner wall of the first fixed frame 3 by means of the power generated by the rolling and the linkage relationship formed by the mechanical connection of each component, and the second sliding frame 121 is connected to the clamping mechanism 13, and finally the clamped steel plate is turned synchronously with the clamping mechanism 13 to complete the turning operation.

[0037] The inner wall of the first sliding frame 9 is slidably connected to the outer surface of the rotating shaft 8, and the inner wall of the first sliding frame 9 at one end away from the rotating shaft 8 is slidably connected to the fixed shaft 6. The inner wall of the first sliding frame 9 is fixedly connected with a first hydraulic rod 10, and the output end of the first hydraulic rod 10 is fixedly connected to the welding equipment 11. The fixed shaft 6 is used to improve the stability of the first sliding frame 9 during movement. When welding operations are performed on the steel plate, the first drive motor 7 starts to run, and drives the first sliding frame 9 to slide along the fixed shaft 6 with the help of the rotating shaft 8. During the sliding process of the first sliding frame 9, the first hydraulic rod 10 fixedly connected to its inner wall moves synchronously therewith, and the first hydraulic rod 10 steadily pushes the welding equipment 11 to one side of the steel plate. When the welding equipment 11 reaches a suitable position, welding operations are carried out on a pre-set weld area of ​​the steel plate.

[0038] Example 2: Please refer to Figure 4-Figure 5 , Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: an arc-shaped spring plate 124 is fixedly connected to the inner wall of the second sliding frame 121, and the inner wall of one end of the arc-shaped spring plate 124 away from the second sliding frame 121 is rotatably connected to the first auxiliary roller 125 through a rotating shaft. During operation, when the steel plate contacts the first auxiliary roller 125 and applies pressure to it, the first auxiliary roller 125 is subjected to force and then squeezes the arc-shaped spring plate 124, and the arc-shaped spring plate 124 is fixed on both sides of the inner wall of the second sliding frame 121. After being subjected to the squeezing force from the steel plate transmitted by the first auxiliary roller 125, the arc-shaped spring plate 124 has a tendency to recover its deformation based on its own elasticity, and forms a reaction force with the help of this tendency, thereby pushing the first auxiliary roller 125 to change the position of the steel plate, thereby prompting the steel plate to move toward the central area of ​​the second sliding frame 121.

[0039] The inner wall of the second sliding frame 121 is fixedly connected with the first telescopic rod 129, the output end of the first telescopic rod 129 is fixedly connected with the first connecting frame 1210, the outer wall of the first connecting frame 1210 is fixedly connected with the second driving motor 1211, the output end of the second driving motor 1211 passes through the first connecting frame 1210 and is fixedly connected with the driving roller 1212. When working, the first telescopic rod 129 starts to work and extends outward, pushing the driving roller 1212 to move toward the direction of the steel plate until the driving roller 1212 is in close contact with the surface of the steel plate, and then the second driving motor 1211 starts to drive the driving roller 1212 connected thereto to rotate, and with the help of the friction between the driving roller 1212 and the steel plate, the driving roller 1212 rolls and pushes the steel plate to continuously move toward the side of the welding equipment 11 to meet the position requirements of subsequent welding operations.

[0040] The outer wall of the first connecting frame 1210 on one side close to the second sliding frame 121 is fixedly connected to the first connecting shaft 1213, and the first connecting shaft 1213 is slidably connected to the inner wall of the second sliding frame 121. The first connecting frame 1210 on one side close to the first connecting shaft 1213 is fixedly connected with a first spring 1214, and the end of the first spring 1214 away from the first connecting frame 1210 is fixedly connected to the second sliding frame 121. During operation, the first telescopic rod 129 pushes the first connecting frame 1210 to move toward the side of the steel plate, and the first connecting frame 1210 slides with the second sliding frame 121 along the first connecting shaft 1213 to make its own movement more stable. Then, the second driving motor 1211 drives the driving roller 1212 to drive the steel plate to move toward the side of the welding equipment 11, and the first spring 1214 fixed between the second sliding frame 121 and the first connecting frame 1210 absorbs the vibration caused by the movement of the steel plate.

[0041] Example 3: Please refer to Figure 6-Figure 7 On the basis of the first and second embodiments, the present invention provides a technical solution: a dual-axis motor 135 is fixedly connected to the inner wall of the rotating frame 131 away from the second sliding frame 121, and the output end of the dual-axis motor 135 is fixedly connected to the second connecting frame 136, and the inner wall of the second connecting frame 136 is fixedly connected to the second telescopic rod 137, and the output end of the second telescopic rod 137 is fixedly connected to the second fixed frame 138. When working, the second hydraulic rod 126 is started and pulls the connecting block 127, and the connecting block 127 is forced to move to cause the auxiliary wheel 128 to slide on the inner wall of the through hole 132 of the rotating frame 131, so that the rotating frame 131 is flipped toward one side of the steel plate. At the same time, the dual-axis motor 135 drives the second connecting frame 136 to flip toward one side of the steel plate synchronously, and the second telescopic rod 137 pushes the second fixed frame 138 toward one side of the steel plate. The steel plates of different thicknesses can be clamped and fixed by the flipping angle of the rotating frame 131.

[0042] A second auxiliary roller 133 is movably sleeved on the inner wall of one side of the rotating frame 131 close to the dual-axis motor 135, and an elastic component 134 is provided on the inner wall of the second auxiliary roller 133. The second auxiliary roller 133 is used to assist the sliding of the steel plate. There are two second auxiliary rollers 133, and the two second auxiliary rollers 133 are symmetrically arranged with the central axis of the rotating frame 131 as the center. During operation, as the rotating frame 131 flips, the second auxiliary roller 133 thereon flips toward one side of the steel plate until it contacts the outer surface of the steel plate, and then applies an extrusion force to the steel plate. Under this extrusion, the elastic component 134 associated with the second auxiliary roller 133 is deformed by the force. With the deformation characteristics of the elastic component 134, the second auxiliary roller 133 can better fit the steel plate and increase the contact area between the two. When the driving roller 1212 is driven to drive the steel plate to move, the second auxiliary roller 133 provides an auxiliary effect on the movement of the steel plate based on its own contact state with the steel plate.

[0043] The inner wall of one end of the second fixing frame 138 away from the second telescopic rod 137 is rotatably connected with a pressing plate 139 through a rotating shaft, and one end of the pressing plate 139 away from the second fixing frame 138 is fixedly connected with an anti-skid pad 1310, and the pressing plate 139 is used to clamp and fix the steel plate, and the anti-skid pad 1310 is used to increase the friction between the pressing plate 139 and the steel plate. The outer wall of one side of the pressing plate 139 close to the second fixing frame 138 is fixedly connected with a second connecting shaft 1311, and the end of the second connecting shaft 1311 away from the pressing plate 139 passes through the second fixing frame 138 and is fixedly connected with a second spring 1312. The second telescopic rod 137 pushes the second fixing frame 138 to move toward one side of the steel plate. As the second fixing frame 138 approaches the steel plate, the pressure plate 139 connected to the inner wall rotates and touches the steel plate. In the process of continuing to advance, with the help of the connecting action of the second connecting shaft 1311, the pressure plate 139 stretches the second spring 1312. At the same time, the anti-slip gasket 1310 fixedly connected to the bottom of the pressure plate 139 fits tightly against the surface of the steel plate. The friction between the anti-slip gasket 1310 and the steel plate is used to clamp and fix the steel plate to prevent it from slipping due to the excessive inclination angle of the steel plate during the turning operation.
