Description

Technical Field

[0001] The present invention relates to the technical field of electromechanical installation, and in particular to a welding device and a method thereof for electromechanical installation. Background Art

[0002] In the process of electromechanical installation, welding is required to complete the installation and fixing of corresponding objects. The welding equipment mainly includes welding tongs, welding rods, electric heating equipment, etc. The overall structure is simple and the manufacturing cost is low. In the actual working process, the main function of the welding clamp is to transmit current and clamp the welding rod in the welding clamp. When welding, the welding rod is electrically heated and located on the outside of the welding surface. The welding clamp can be moved along the weld. The operation is simple, but in the actual processing process, the welding clamp can only complete the clamping and fixing operation of the welding rod. The welding rod and the welding clamp are in a fixed state. In the process of moving the welding clamp, it is necessary not only to control the movement trajectory of the welding clamp, but also to maintain the spacing between the welding rod and the weld, which is relatively complicated. In the welding process, it is necessary to adjust the position of the welding rod relative to the welding clamp many times to maintain the overall welding effect, which greatly delays the overall welding work. After welding is completed, it is necessary to clean the area around the weld and manually check the welding effect. It is time-consuming and laborious. Sometimes it is difficult to completely perform the above-mentioned cleaning and detection work due to the obstruction of the electromechanical device. Therefore, a welding device and method for electromechanical installation are provided. Summary of the invention

[0007] Preferably, a detection assembly is installed on the upper side of the shell, and the detection assembly includes a limit rod fixedly installed on the side walls of the two cleaning plates, the outer sides of the two limit rods are slidably connected with an intermediate cylinder, a sixth spring is fixedly connected between the two limit rods and the intermediate cylinder, a sixth connecting rod is fixedly connected to the upper side of the intermediate cylinder, a sleeve is slidably connected to the upper side of the sixth connecting rod, a seventh spring is fixedly connected between the sixth connecting rod and the sleeve, a pressure sensor is also fixedly connected between the sleeve and the sixth connecting rod, and a detection plate is fixedly connected to the outer side of the sleeve.

[0008] Preferably, the upper side of the detection plate is arc-shaped, and the surface of the detection plate is smooth.

[0009] Preferably, an insulating sleeve is fixedly connected to the outer side of the shell, and a heat-insulating sleeve is fixedly connected to the outer side of the insulating sleeve.

[0010] Preferably, four slide grooves are symmetrically opened in pairs in the shell, and slide rods are slidably connected in the four slide grooves, and the slide rods are fixedly connected to the second connecting plate.

[0011] A method for welding equipment for electromechanical installation, comprising the steps of: S1. First, clean the surface to be welded and keep the welding surface clean; S2. Then, select a suitable welding rod, insert the welding rod into the through hole, and fix the welding rod in the housing; S3, then, electrically heat the welding, rotate the shaft and move the shell at the same time, so that welding can be carried out; S4. Finally, after welding is completed, the surface of the weld and the welding position are cleaned and inspected, the welding quality is inspected, and finally the overall welding operation is completed.

[0012] The beneficial effects of the present invention are: 1. First, during the welding process, the electrode is clamped and installed in the shell. Then, during welding, the electrode can be moved by simply rotating the shaft. No manual adjustment is required. The operation is simple and can greatly maintain the welding effect. In addition, during the welding process, there is no need to adjust the position of the electrode midway, which greatly improves the welding efficiency. 2. Then, after welding is completed, the cleaning plate can be used to clean the position next to the welding seam. In this process, the cleaning plate will not only move with the shell, but also move back and forth relative to the shell. The cleaning plate will clean the protrusions that may fall next to the weld. The cleaning plate is used for cleaning. In this process, the protrusions will hinder the movement of the cleaning plate. The staff can clearly feel this resistance. If the resistance is large, it means that there are major problems in the welding process and corresponding inspections are required; 3. Finally, when using the cleaning plate to clean the area around the weld, the detection plate and the welding surface are against each other, which will cause the pressure sensor to send out a corresponding electrical signal. During this process, you can always observe the electrical signal sent by the pressure sensor. When the electrical signal sent by the pressure sensor is too large, it means that the welding surface here is high and needs to be processed in time to reduce the impact on subsequent connection work. When the electrical signal sent by the pressure sensor is too small, it means that the welding surface is low at this time, and the connection stability here is poor, which requires timely remediation.

[0016] like Figure 6 , Figure 7 , Figure 8A cleaning assembly is installed on the upper side of the housing 1, and the cleaning assembly includes a third rotating plate 23 fixedly installed on the outer side of the rotating shaft 20, and a plurality of third rotating rods 24 are fixedly connected to the outer circumferential direction of the third rotating plate 23. A fourth connecting rod 25 is fixedly connected to the upper side of the slider 3, and the upper side of the fourth connecting rod 25 penetrates the housing 1 and is fixedly connected to a trapezoidal plate 26. Two slide plates 28 are slidably connected to the upper side of the housing 1, and a fifth spring 29 is fixedly connected between the two slide plates 28 and the housing 1. A seventh connecting rod is fixedly connected to the upper sides of the two slide plates 28. 27, one end of the two seventh connecting rods 27 close to the trapezoidal plate 26 is provided with an inclined surface matching the trapezoidal plate 26, the side walls of the two seventh connecting rods 27 are fixedly connected with a square rod 30, the end of the square rod 30 is fixedly connected with a fourth connecting plate 31, the outer side of the square rod 30 is slidably connected with a fifth connecting plate 32, a fourth spring 33 is fixedly connected between the fifth connecting plate 32 and the fourth connecting plate 31, a cleaning plate 34 is fixedly connected to the upper side of the fifth connecting plate 32, and a fifth connecting rod 35 is fixedly connected to the lower side of the cleaning plate 34; After welding is completed, the upper end of the shell 1 can be made to face the weld, and the welding rod has been taken out of the through hole 2. Then the rotating block 6 is rotated clockwise, and the rotating block 6 drives the first connecting plate 7 to rotate. The first connecting plate 7 and the slider 3 are against each other and drive the slider 3 to move to the right. The slider 3 drives the trapezoidal plate 26 to move through the fourth connecting rod 25. The trapezoidal plate 26 and the seventh connecting rod 27 are against each other. Under the restriction of the slide plate 28, the seventh connecting rod 27 is moved away from each other. The slide plate 28 stretches the fifth spring 29. At the same time, the seventh connecting rod 27 drives the square rod 30 to move away from each other. The square rod 30 drives the cleaning plate 34 to move through the fifth connecting plate 32, thereby expanding the distance between the two cleaning plates 34 until the distance between the two cleaning plates 34 is greater than the width of the weld. Then move the shell 1 so that the shell 1 drives the cleaning plate 34 to move until the gap between the cleaning plate 34 and the object to be welded is small. During the welding process, the welding surface and the upper end surface of the shell 1 are in a vertical state, and there is a certain distance between the upper end surface of the shell 1 and the welding surface. Although the cleaning plate 34 will also move during welding, it will not affect the welding work. Then move the shell 1 as a whole along the direction of the weld, and in this process, rotate the shaft 20, the shaft 20 drives the third rotating plate 23 and the third rotating rod 24 to rotate, the third rotating rod 24 and the fifth connecting rod 35 abut against each other and drive the fifth connecting rod 35 to move along the square rod 30, the fifth connecting rod 35 drives the cleaning plate 34 to move, and the cleaning plate 34 drives the fifth connecting plate 32 to move, so as to Figure 8Based on the direction of rotation, based on the clockwise rotation of the rotating shaft 20, the rotating shaft 20 drives the third rotating plate 23 and the third rotating rod 24 to rotate clockwise. When the third rotating rod 24 and the fifth connecting rod 35 on the left side abut against each other, the third rotating rod 24 drives the fifth connecting rod 35 to move backward along the square rod 30, and the fifth connecting rod 35 drives the cleaning plate 34 to move backward. The cleaning plate 34 drives the fifth connecting plate 32 to move backward. The fifth connecting plate 32 stretches the fourth spring 33. When the third rotating rod 24 and the fifth connecting plate 35 on the right side abut against each other, the third rotating rod 24 drives the fifth connecting rod 35 to move backward along the square rod 30. The third rotating rod 24 drives the fifth connecting rod 35 to move forward along the square rod 30, the fifth connecting rod 35 drives the cleaning plate 34 to move forward, the fifth connecting rod 35 drives the cleaning plate 34 to move forward, the cleaning plate 34 drives the fifth connecting plate 32 to move forward, the fifth connecting plate 32 compresses the fourth spring 33, and when the third rotating rod 24 and the fifth connecting rod 35 are disconnected, the cleaning plate 34 will return to its original position relative to the housing 1 under the action of the fifth spring 29, resulting in that in this process, the cleaning plate 34 will not only follow the housing 1 to move forward, but also move back and forth. The cleaning plate 34 will also move back and forth relative to the shell 1. In the above process, the cleaning plates 34 on both sides will move simultaneously (the structure and principle that cause the cleaning plates 34 on both sides to move simultaneously are described below), and the spacing between the third rotating rods 24 is relatively large. When the third rotating rod 24 is against the fifth connecting rod 35 on one side, the other third rotating rods 24 will not be against the fifth connecting rod 35 on the other side. The cleaning plates 34 will clean the protrusions that may fall next to the weld (the reason for the formation of this protrusion is that during the welding process, the welding rod melts under high temperature to form liquid that falls on the surface of the weld. Due to a certain temperature difference between the weld surface and the melted welding rod liquid, some liquid will splash around the weld, and the liquid will fall around the weld to form protrusions). The cleaning plates 34 are used for cleaning to maintain the normal working effect of the weld. In this process, the protrusions will hinder the movement of the cleaning plates 34, and the staff can clearly feel this resistance. If the resistance is large, it means that there are major problems in the welding process and corresponding inspections are required.

[0017] like Fig. 9 , Fig.10 A detection assembly is installed on the upper side of the housing 1, and the detection assembly includes a limit rod 36 fixedly installed on the side walls of the two cleaning plates 34, and an intermediate cylinder 37 is slidably connected to the outer sides of the two limit rods 36. A sixth spring 38 is fixedly connected between the two limit rods 36 and the intermediate cylinder 37, and a sixth connecting rod 39 is fixedly connected to the upper side of the intermediate cylinder 37. A sleeve 40 is slidably connected to the upper side of the sixth connecting rod 39, and a seventh spring 41 is fixedly connected between the sixth connecting rod 39 and the sleeve 40. A pressure sensor 42 is also fixedly connected between the sleeve 40 and the sixth connecting rod 39, and a detection plate 43 is fixedly connected to the outer side of the sleeve 40; First, the pressure sensor 42 is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. Secondly, under the action of the limit rod 36 and the intermediate cylinder 37, the two cleaning plates 34 will move at the same time. Under the action of the limit rod 36 and the sixth spring 38, the intermediate cylinder 37 is always located in the middle position of the two cleaning plates 34. Then, when the cleaning plate 34 is used to clean the area around the weld, the detection plate 43 and the welding surface are abutted, and the sixth spring 38 is in a compressed state. In this process, since the surface of the detection plate 43 is a smooth arc, the welding surface is not It will not hinder the detection plate 43 from following the movement of the cleaning plate 34. Then, in the process of the detection plate 43 following the movement of the cleaning plate 34, since the detection plate 43 and the welding surface are always against each other, the pressure sensor 42 will send out a corresponding electrical signal. During this process, the electrical signal sent out by the pressure sensor 42 can be observed all the time. When the electrical signal sent out by the pressure sensor 42 is too large, it means that the welding surface here is high, and timely processing is required to reduce the impact on subsequent connection work. When the electrical signal sent out by the pressure sensor 42 is too small, it means that the welding surface at this time is low, and the connection stability here is poor, and timely remediation is required.

[0018] A method for welding equipment for electromechanical installation, comprising the steps of: S1. First, clean the surface to be welded and keep the welding surface clean; S2, then, select a suitable welding rod, insert the welding rod into the through hole 2, and fix the welding rod in the housing 1; S3, then, electrically heat the welding, rotate the shaft 20 and move the housing 1 at the same time, and then weld; S4. Finally, after welding is completed, the welding surface and welding position are cleaned and inspected, the welding quality is inspected, and the overall welding operation is finally completed. In the present invention, when welding operation is required, first press the rotating block 6 to make the rotating block 6 rotate clockwise with the positioning rod 5 as the center, and the rotating block 6 drives the first connecting plate 7 to rotate. The first connecting plate 7 and the slider 3 abut against each other and drive the slider 3 to move to the right. The slider 3 stretches the first spring 4 and expands the distance between the first connecting tube 10 and the second connecting tube 13. Select a suitable welding rod and pass the welding rod through the through hole 2. At this time, the welding rod is located between the first connecting tube 10 and the second connecting tube 13, and the rotating block 6 is released. At this time, under the action of the first spring 4, the slider 3 moves to the left as a whole until the first connecting tube 10, the welding rod, and the second connecting tube 13 are tightly abutted against each other. Compared with when the welding rod does not pass through the through hole 2, after the welding rod passes through the through hole 2, the welding rod and the first connecting tube 10 and the second connecting tube 13 abut against each other, which will expand the distance between the first connecting tube 10 and the second connecting tube 13. The spacing will cause the first spring 4 to be in a stretched state, the second spring 15 to be in a compressed state, and the elastic force of the first spring 4 is equal to the elastic force of the second spring 15, and the first connecting plate 7 and the slider 3 are not in contact, and then the housing 1 is held and moved to a suitable working position, and then the shaft 20 is manually rotated through the through slot 19, and the shaft 20 drives the second rotating plate 21 and the second rotating rod 22 to rotate, and the second rotating rod 22 and the first rotating rod 18 are against and drive the first rotating rod 18 and the first rotating plate 17 to rotate, and the first rotating plate 17 drives the second connecting rod 12 to rotate through the third connecting rod 16, and the second connecting rod 12 drives the second connecting tube 13 to rotate, so that the welding rod can be moved relative to the housing 1, so that during the welding process, the position of the end of the welding rod can be better adjusted, thereby ensuring the welding quality; After welding is completed, the upper end of the shell 1 can be made to face the weld, and the welding rod has been taken out of the through hole 2. Then the rotating block 6 is rotated clockwise, and the rotating block 6 drives the first connecting plate 7 to rotate. The first connecting plate 7 and the slider 3 are against each other and drive the slider 3 to move to the right. The slider 3 drives the trapezoidal plate 26 to move through the fourth connecting rod 25. The trapezoidal plate 26 and the seventh connecting rod 27 are against each other. Under the restriction of the slide plate 28, the seventh connecting rod 27 is moved away from each other. The slide plate 28 stretches the fifth spring 29. At the same time, the seventh connecting rod 27 drives the square rod 30 to move away from each other. The square rod 30 drives the cleaning plate 34 to move through the fifth connecting plate 32, thereby expanding the distance between the two cleaning plates 34 until the distance between the two cleaning plates 34 is greater than the width of the weld. Then move the shell 1 so that the shell 1 drives the cleaning plate 34 to move until the gap between the cleaning plate 34 and the object to be welded is small. During the welding process, the welding surface and the upper end surface of the shell 1 are in a vertical state, and there is a certain distance between the upper end surface of the shell 1 and the welding surface. Although the cleaning plate 34 will also move during welding, it will not affect the welding work. Then move the shell 1 as a whole along the direction of the weld, and in this process, rotate the shaft 20, the shaft 20 drives the third rotating plate 23 and the third rotating rod 24 to rotate, the third rotating rod 24 and the fifth connecting rod 35 abut against each other and drive the fifth connecting rod 35 to move along the square rod 30, the fifth connecting rod 35 drives the cleaning plate 34 to move, and the cleaning plate 34 drives the fifth connecting plate 32 to move, so as to Figure 8Based on the direction of rotation, based on the clockwise rotation of the rotating shaft 20, the rotating shaft 20 drives the third rotating plate 23 and the third rotating rod 24 to rotate clockwise. When the third rotating rod 24 and the fifth connecting rod 35 on the left side abut against each other, the third rotating rod 24 drives the fifth connecting rod 35 to move backward along the square rod 30, and the fifth connecting rod 35 drives the cleaning plate 34 to move backward. The cleaning plate 34 drives the fifth connecting plate 32 to move backward. The fifth connecting plate 32 stretches the fourth spring 33. When the third rotating rod 24 and the fifth connecting plate 35 on the right side abut against each other, the third rotating rod 24 drives the fifth connecting rod 35 to move backward along the square rod 30. The third rotating rod 24 drives the fifth connecting rod 35 to move forward along the square rod 30, the fifth connecting rod 35 drives the cleaning plate 34 to move forward, the fifth connecting rod 35 drives the cleaning plate 34 to move forward, the cleaning plate 34 drives the fifth connecting plate 32 to move forward, the fifth connecting plate 32 compresses the fourth spring 33, and when the third rotating rod 24 and the fifth connecting rod 35 are disconnected, the cleaning plate 34 will return to its original position relative to the housing 1 under the action of the fifth spring 29, resulting in that in this process, the cleaning plate 34 will not only follow the housing 1 to move forward, but also move back and forth. The cleaning plate 34 will also move back and forth relative to the housing 1. In the above process, the cleaning plates 34 on both sides will move simultaneously (the structure and principle that cause the cleaning plates 34 on both sides to move simultaneously are described below), and the spacing between the third rotating rods 24 is relatively large. When the third rotating rod 24 abuts against the fifth connecting rod 35 on one side, the other third rotating rods 24 will not abut against the fifth connecting rod 35 on the other side. The cleaning plate 34 will clean the protrusions that may fall next to the weld (the reason for the formation of this protrusion is that during the welding process, the welding rod melts under high temperature to form liquid that falls on the surface of the weld. Due to a certain temperature difference between the surface of the weld and the melted welding rod liquid, some liquid will splash around the weld, and the liquid falls around the weld to form protrusions). The cleaning plate 34 is used for cleaning to maintain the normal working effect of the weld. In this process, the protrusions will hinder the movement of the cleaning plate 34, and the staff can clearly feel this resistance. If the resistance is large, it means that there are major problems in the welding process and corresponding inspections are required. Under the action of the limit rod 36 and the sixth spring 38, the intermediate cylinder 37 is always located in the middle position of the two cleaning plates 34. Then, when the cleaning plate 34 is used to clean the area around the weld, the detection plate 43 and the welding surface are against each other, and the sixth spring 38 is in a compressed state. During this process, since the surface of the detection plate 43 is a smooth arc, the welding surface will not hinder the detection plate 43 from moving with the cleaning plate 34. Then, in the process of the detection plate 43 moving with the cleaning plate 34, since the detection plate 43 and the welding surface are always against each other, the pressure sensor 42 will send out a corresponding electrical signal. During this process, the electrical signal sent by the pressure sensor 42 can be observed all the time. When the electrical signal sent by the pressure sensor 42 is too large, it means that the welding surface here is high and needs to be processed in time to reduce the impact on subsequent connection work. When the electrical signal sent by the pressure sensor 42 is too small, it means that the welding surface is low at this time and the connection stability here is poor, which needs to be remedied in time.
