Description

Technical Field

[0001] The utility model relates to the field of welding, and specifically to a welding and cutting integrated structure. Background Art

[0002] The resistance welding equipment includes a spot welding station and a shearing station. In the prior art, the spot welding station and the shearing station are distributed at different positions. Therefore, during the welding process of materials at one time, it is necessary to first perform spot welding operation at the spot welding station, and then the conveying structure conveys it to the shearing station to cut off the redundant part. As shown in the following patents:

[0003] The authorized announcement number CN209919202U discloses a carbon brush welding and assembling machine, which specifically discloses that: the indexing plate 6 is successively provided with a clamping station 4, a welding station 8, a shearing station 9, and a blanking station 3 in the counterclockwise direction when viewed from above. A spot welder 7 is provided on the machine table 1 corresponding to the welding station 8 of the indexing plate 6. The welding point of the spot welder 7 is located between the brush holder 23 and the base 14 on the carbon brush fixture 5 at the welding station 8 of the indexing plate 6. A pair of scissors 10 is provided on the machine table 1 corresponding to the shearing station 9 of the indexing plate 6. The shearing point of the pair of scissors 10 is located between the brush holder 23 and the base 14 on the carbon brush fixture 5 at the shearing station 9 of the indexing plate 6. Clamping cylinders 2 are provided on the machine table 1 directly below the clamping station 4 and the blanking station 3 of the indexing plate 6.

However, there are still the following problems: since the electric welding machine and the scissors are arranged at workstations in different positions, it is necessary to pass through two workstations every time the welding and shearing operations are completed, resulting in reduced work efficiency.

[0039] The following further elaborates on the utility model in conjunction with the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the protection scope of the utility model.

[0040] Please refer to Figures 1-9 , a welding integrated structure 100, including a lower electrode 1, a moving structure 2, a shearing member 3, a first driving member 4, and a second driving member 5. A guiding hole 21 and an upper electrode 6 are provided on the moving structure 2. The shearing member 3 is arranged in the guiding hole 21 and moves back and forth in the guiding hole 21. The driving end of the first driving member 4 is connected to the moving structure 2, and the driving end of the second driving member 5 is connected to the shearing member 3. During operation, the first driving member 4 drives the moving structure 2 to move towards the lower electrode 1, and the upper electrode 6 and the lower electrode 1 weld the workpiece clamped therebetween; after welding is completed, the second driving member 5 drives the shearing member 3 to move in the guiding hole 21, and the shearing member 3 shears the workpiece.

[0041] In this embodiment, the moving structure 2 includes a moving plate 22. The upper part of the first end of the moving plate 22 is recessed inward to form a first installation space 221, and at this time, a stepped shape is formed between the upper and lower parts of the first end of the moving plate 22. A first groove 222 is recessed inward along the vertical direction at the lower part of the first end of the moving plate 22. The degree of inward recess of the first groove 222 is the same as that of the upper part of the first end of the moving plate 22, that is, at this time, the first groove 222 and the upper part of the first end of the moving plate 22 are just located on the same plane. The upper electrode 6 is arranged in the first groove 222, and the thickness of the upper electrode 6 is greater than the inward recess depth of the first groove 222, that is, a part of the top surface of the upper electrode 6 protrudes out of the first groove 222 (the top surface of the upper electrode 6 falls into the first installation space 221). Specifically, an upper electrode pressing plate 223 is further included. The upper electrode pressing plate 223 covers the lower part of the first end of the moving plate 22. The upper electrode pressing plate 223 presses the upper electrode 6 tightly in the first groove 222, and a part of the upper electrode 6 extends downward out of the first groove 222. At this time, the first groove 222 is equivalent to a four-sided enclosed space (specifically, the left side surface, the right side surface, the bottom surface of the first groove 222, and the upper electrode pressing plate 223 serve as the top surface of the first groove 222).

[0042] In this embodiment, the guiding hole 21 is in a groove shape and is recessed along the bottom surface of the first groove 222 to form the guiding hole 21. The guiding hole 21 extends along the length direction of the first groove 222 and penetrates through the upper and lower sides of the first end of the moving plate 22. The width of the guiding hole 21 is smaller than the width of the first groove 222. It further includes a shearing pressure plate 224. The shearing pressure plate 224 is arranged in the first installation space 221 and covers the upper half section of the guiding hole 21.

[0043] Specifically, please refer to Figure 4 , a first recessed portion 2241 is arranged on the upper part of the shearing pressure plate 224. The first recessed portion 2241 is integrally in a "U" shape. A through hole (not marked in the figure) is arranged on the bottom surface of the first recessed portion 2241, and the through hole is communicated with the first groove 222. It further includes an upper electrode adjusting screw 2242. The upper electrode adjusting screw 2242 is arranged in the through hole. One end of the upper electrode adjusting screw 2242 passes through the through hole on the bottom surface of the first recessed portion 2241 and is connected to the upper electrode 6. By adjusting the upper electrode adjusting screw 2242, the upper electrode adjusting screw 2242 can move upward in the direction of the upper electrode 6 and contact the upper electrode 6 to adjust the length of the upper electrode 6 extending out of the first groove 222.

[0044] Preferably, in this embodiment, the upper electrode 6 is made of a material with a relatively large resistance, such as tungsten, molybdenum, copper-tungsten alloy, etc., so as to reduce the current and thereby reduce the wear of the upper electrode 6. And when the resistance of the upper electrode 6 is relatively large, the heat distribution during welding is more uniform, which can reduce the situation of local overheating, and thereby reduce the probability of welding defects such as the solder joint burning through. Of course, the upper electrode 6 can also be made of other materials, which is not limited here.

[0045] In this embodiment, the shearing member 3 includes a shearing head 31, a shearing rod 32 and a shearing connection block 33. The shearing rod 32 is movably arranged in the guiding hole 21. The length of the shearing rod 32 is greater than that of the guiding hole 21, which is the basis for the shearing rod 32 to move along the length direction of the guiding hole 21. Preferably, the ratio of the length of the shearing rod 32 to that of the guiding hole 21 is at least 1.2:1. This is only an example, and this embodiment is not limited thereto. The widths of both the shearing head 31 and the shearing connection block 33 are greater than that of the shearing rod 32. Preferably, the width ratio of the shearing head 31, the shearing rod 32 and the shearing connection block 33 is at least 1.9:1:1.9. This is only an example, and this embodiment is not limited thereto. Moreover, their widths are also greater than that of the guiding hole 21. On the other hand, the top surface of the lower end of the guiding hole 21 is covered by the upper electrode 6, and the top surface of the upper end of the guiding hole 21 is covered by the shearing pressing plate 224. Therefore, at this time, the guiding hole 21 is equivalent to a four-sided enclosed space (specifically, the left side surface of the guiding hole 21, the right side surface of the guiding hole 21, the bottom surface of the guiding hole 21 and the combined surface of the upper electrode 6 and the shearing pressing plate 224 serve as the top surface of the guiding hole 21), preventing the shearing rod 32 from disengaging from the guiding hole 21 in the horizontal direction. Further, since the widths of the aforementioned shearing head 31 and the shearing connection block 33 are greater than that of the guiding hole 21, when the shearing rod 32 moves back and forth along the length direction of the guiding hole 21 under the drive of the second driving member 5, the shearing head 31 can correspondingly abut against the lower end of the moving plate 22, and the shearing connection block 33 can correspondingly abut against the upper end of the moving structure 2, preventing the shearing member 3 from disengaging from the guiding hole 21 in the vertical direction.

[0046] Please refer to Figure 2, in this embodiment, when viewed from the side of the shearing member 3, the shearing head 31 is in the shape of a right trapezoid. In the initial state, the length that the shearing head 31 extends out of the guiding hole 21 is less than the length that the upper electrode 6 extends out of the first groove 222. Preferably, the ratio of the length that the shearing head 31 extends out of the guiding hole 21 to the length that the electrode extends out of the first groove 222 is at least 1:1.3. This is only an example, and this embodiment is not limited thereto. The functions of this design are as follows: First, ensure that the upper electrode 6 first contacts the workpiece and completes the welding, and then perform the cutting. Otherwise, if the shearing head 31 and the upper electrode 6 are on the same horizontal plane, the workpiece will be cut by the shearing head 31 before the upper electrode 6 and the lower electrode 1 start to form a circuit for welding. Second, after the welding operation of the workpiece, the welded part will become fragile. At this time, driving the shearing head 31 to perform the cutting can ensure the integrity of the cutting position. If the shearing head 31 cuts too early, it may cause the welded part of the workpiece to deform or the cutting to be incomplete. Third, heat will be generated when the upper electrode 6 and the lower electrode 1 contact to form a circuit. These heats will affect the material of the object. If the shearing head 31 contacts the workpiece too early, it may be affected by the high temperature generated by the welding, resulting in poor cutting effect or damage to the shearing head 31. Therefore, the extended length of the shearing head 31 is set to be a little shorter than the extended length of the upper electrode 6, which can ensure that the cutting operation is carried out under relatively stable heat conditions.

[0047] In this embodiment, the shearing connection block 33 is connected to the driving end of the second driving member 5. Specifically, a mounting seat 225 is provided on the top surface of the moving plate 22, and the second driving member 5 is arranged on the mounting seat 225. A first through hole 2251 is formed in the mounting seat 225, and the driving end of the second driving member 5 passes through the first through hole 2251 and is connected to the shearing connection block 33 on the shearing member 3.

[0048] Specifically, please refer to Figure 5 , including a first connecting member 226. One end of the first connecting member 226 is connected to the driving end of the second driving member 5, and a second recessed portion 2262 is provided at the other end of the first connecting member 226. A second through hole 2261 is formed on the side surface of the second recessed portion 2262. Correspondingly, the shearing connection block 33 on the shearing member 3 matches the size of the second recessed portion 2262, and a third through hole 331 is formed on the surface of the shearing connection block 33. Insert the shearing connection block 33 into the second recessed portion 2262, and then use a hinge pin 2263 to pass through the second through hole 2261 and the third through hole 331 at the same time, and the second driving member 5 and the shearing member 3 can be connected. Of course, in addition to the hinge pin 2263, other pin-like components can also be used, which are not limited here.

[0049] Specifically, in this embodiment, the second driving member 5 is a cylinder.

[0050] In this embodiment, a gap adjusting member 7 is provided through the bottom surface of the guiding hole 21. Please refer to Figure 6 , the gap adjusting member 7 includes a gap adjusting screw 71 and a gap adjusting nut 72. When the gap adjusting screw 71 is engaged with a threaded hole (not shown in the figure) provided on the bottom surface of the guiding hole 21, it can push the shearing rod 32 (connecting the shearing head 31 and the shearing connection block 33) to move back and forth in the direction of the upper electrode 6. Thereby, the distance between the shearing head 31 and the upper electrode 6 is controlled to avoid the situation that when the shearing member 3 slides and rubs in the guiding hole 21 for a long time, the gap of the guiding hole 21 becomes larger and the shearing member 3 moves away from the upper electrode 6. That is, by adjusting the gap adjusting screw 71, it can be ensured that the shearing member 3 always abuts against the upper electrode 6. The gap adjusting nut 72 is sleeved on the gap adjusting screw 71, and as a limiting function, one end of the gap adjusting nut 72 abuts against the side surface of the moving structure 2 to prevent the gap adjusting screw 71 from loosening and shifting.

[0051] Preferably, the number of the gap adjusting members 7 is two, and the two gap adjusting members 7 are arranged on the bottom surface of the guiding hole 21 at a predetermined distance along the length direction of the guiding hole 21.

[0052] In this embodiment, a backing plate 227 is further provided on the top surface of the moving plate 22, and the backing plate 227 is fixedly arranged on the top surface of the moving plate 22. When the driving end of the first driving member 4 moves towards the moving plate 22, it can contact the backing plate 227 and drive the moving plate 22 to move towards the fixing plate 81, thereby avoiding the direct contact between the driving end of the first driving member 4 and the moving plate 22.

[0053] Specifically, in this embodiment, the first driving member 4 is a cylinder.

[0054] In this embodiment, a guiding structure 228 is movably provided on the side surface of the moving plate 22, and the moving plate 22 can move back and forth smoothly under the action of the guiding structure 228. Specifically, the guiding structure 228 includes a slider 2281 and a slide rail 2282. Further, fixing blocks 2283 are provided on the left and right side surfaces of the slider 2281, and through holes (not shown in the figure) are provided in the fixing blocks 2283. Parts such as screws and bolts can be used to connect the fixing blocks 2283 to the bottom surface of the insulating plate 2284.

[0055] Preferably, two sliders 2281 and two slide rails 2282 are provided, the bottom surfaces of the two sliders 2281 are movably connected to the corresponding slide rails 2282, the top surfaces of the two sliders 2281 are on the same horizontal plane, and are fixedly arranged on the bottom surface of the insulating plate 2284 at a predetermined distance, and the top surface of the insulating plate 2284 is fixedly connected to the side surface of the moving plate 22. This structure enables the moving plate 22 to achieve high-precision linear motion when the first driving member 4 drives the moving plate 22 to move back and forth. At the same time, the slide rail 2282 can withstand a large load, and can disperse the load, reduce point contact pressure, and thus extend the service life.

[0056] In this embodiment, the integrated welding structure 100 further includes a fixed structure 8. Specifically, the fixed structure 8 includes a fixed plate 81 disposed opposite to the movable plate 22, and the fixed plate 81 is disposed below the movable plate 22. Figure 9 , the upper part of the first end of the fixed plate 81 is concave to form a second installation space 82, and the bottom surface of the second installation space 82 is further concave to form a second groove 83, and the second groove 83 runs through the upper and lower ends of the fixed plate 81 at the same time. The lower electrode 1 is arranged in the second groove 83, and the thickness of the lower electrode 1 is greater than the concave depth of the second groove 83, that is, the top surface of the lower electrode 1 partially exposes the second groove 83 (the top surface of the lower electrode 1 falls into the second installation space 82). The fixed plate 81 also includes a lower electrode pressing plate 84, the size of the lower electrode pressing plate 84 matches the second installation space 82, so the lower electrode pressing plate 84 is arranged in the second installation space 82, and the lower electrode 1 is pressed against the second groove 83. Specifically, at this time, the second groove 83 is equivalent to a four-sided closed space (specifically, the left side of the second groove 83, the right side of the second groove 83, the bottom surface of the second groove 83 and the lower electrode pressing plate 84 as the top surface of the second groove 83), so that it can be ensured that the lower electrode 1 will not be separated from the second groove 83 in the horizontal direction.

[0057] Specifically, a support member 85 is provided at the lower part of the first end of the fixed plate 81, and the support member 85 can give the lower electrode 1 an upward force to accurately adjust the length of the lower electrode 1 extending out of the second groove 83, so as to avoid the lower electrode 1 from being unable to contact with the upper electrode 6 and form a loop after being worn and shortened due to long-term use. Further, the support member 85 includes a support plate 851 and a support rod 852, the support plate 851 is fixedly provided at the lower part of the first end of the fixed plate 81, and a through hole (not shown in the figure) is provided on the support plate 851, which is connected to the second groove 83. The support rod 852 is penetrated in the through hole, and an external thread is provided on the surface of the support rod 852, and an internal thread is provided on the inner wall of the through hole. Under the cooperation of the external thread and the internal thread, one end of the support rod 852 abuts against the lower electrode 1. The support rod 852 gives the lower electrode 1 an upward supporting force, so as to accurately adjust the length of the lower electrode 1 extending out of the second groove 83.

[0058] Preferably, in this embodiment, the lower electrode 1 is made of a highly conductive material, such as copper alloy, to reduce the resistance and heat generation of the lower electrode 1 itself. Of course, the lower electrode 1 can also be made of other materials, which is not limited here.

[0059] The working principle of the present utility model will be introduced below for better understanding:

[0060] First, place the two workpieces to be welded between the upper electrode 6 and the lower electrode 1. The first driving member 4 drives the insulating plate 2284 to drive the upper electrode 6 and the shearing member 3 to move towards the lower electrode 1. The upper electrode 6 and the lower electrode 1 are cooperatively connected. By applying a certain mechanical pressure, the contact surfaces of the two workpieces are closely contacted. This pressure ensures that the current can effectively pass through the contact surface and prevents the current from dispersing or generating unnecessary arcs. Once the upper electrode 6 and the lower electrode 1 simultaneously contact the workpiece and apply pressure, the current passes through the upper electrode 6, flows through the contact surface of the workpiece, and then forms a loop through the lower electrode 1. Due to the existence of a certain resistance (referred to as contact resistance) at the contact surface, Joule heat will be generated when the current passes through. This heat is concentrated on the contact surface and rapidly raises the temperature. Since the temperature at the contact surface rapidly rises, the metal on the contact surface will start to melt, forming a molten pool. The molten metal fills the tiny gaps between the contact surfaces, forming a common molten area. While continuing to apply pressure, the power supply is stopped, and the molten metal gradually cools and solidifies, forming a firm solder joint. At this time, the two workpieces have been welded together. Secondly, start the second driving member 5. The second driving member 5 drives the shearing member 3 to perform a first cutting on the redundant parts of the two workpieces, only retaining the required parts. Finally, the shearing member 3 and the upper electrode 6 return to their original positions, and one welding and shearing operation ends.

[0061] In the present utility model, a guiding hole 21 and an upper electrode 6 are provided in the moving structure 2, wherein the shearing member 3 is arranged in the guiding hole 21, and the upper electrode 6 is arranged in the first groove 222. The advantages of this design are as follows: First, it allows for independent control of the movement of the shearing member 3 and the upper electrode 6. First, control the upper electrode 6 to perform the welding operation, and then the shearing member 3 moves out of the guiding hole 21 and performs a cutting operation on the workpiece after the welding operation is completed. This separated movement control can avoid mutual interference between the welding and cutting operations, improving the processing accuracy and quality. Second, the design of the guiding hole 21 makes the shearing member 3 and the redundant parts of the workpiece more precise. It can also optimize the space utilization of the moving structure 2, making the structure more compact and lightweight, which is helpful for improving the overall operating speed and response ability of the equipment, and at the same time can reduce the mechanical load. Third, since the shearing member 3 is in the guiding hole 21 in the non-working state, when the fixing plate 81 moves, the damage to the workpiece or other parts is reduced, and the damage to the shearing member 3 caused by external factors is also reduced.

[0062] The present utility model also has a second embodiment. The difference between the second embodiment and the first embodiment is that the shape of the guiding hole 21 is changed, specifically:

[0063] Please refer to Figure 10 , in this embodiment, the guiding hole 21 is in the shape of a through hole. The guiding hole 21 penetrates through the upper and lower ends of the moving structure 2.

[0064] Preferably, in this embodiment, since the guiding hole 21 is in the shape of a through hole, the shearing pressure plate 224 may not be provided, because a four-sided enclosed space has been formed around the guiding hole 21 due to its through-hole shape. Of course, if the function of the shearing pressure plate 224 is to set the upper electrode adjusting screw 2242, the shearing pressure plate 224 may also be retained, which is not limited here.

[0065] Other technical features and technical effects are basically the same as those of the first embodiment and will not be elaborated here.
