Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a welding positioning device. Background Art

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Welding achieves the purpose of joining through the following three ways: The first is fusion welding, which heats the workpieces to be joined to partially melt them to form a molten pool. The molten pool is cooled and solidified before joining. If necessary, molten fillers can be added to assist. It is suitable for welding various metals and alloys without pressure. The second is pressure welding. Pressure must be applied to the weldment during the welding process. It belongs to the processing of various metal materials and partial metal materials. The third is brazing, which uses a metal material with a lower melting point than the parent material as a brazing material, uses liquid brazing material to wet the parent material, fill the joint gap, and diffuse with the parent material to achieve a connection between the welded parts. It is suitable for welding various materials, and also suitable for welding different metals or heterogeneous materials.

[0003] At present, when welding steel plates, most companies align and splice two plates manually, and then press the plates manually to prevent them from shifting during welding. After pressing the plates, the two plates are welded together by the welding machine head.

[0004] The existing welding method has the following shortcomings:

[0005] Manually pressing down the plate and then using the welding machine head for welding not only increases the workers' workload, but also creates greater risks during welding, which can easily lead to work-related injuries. Summary of the invention

[0006] In view of this, the present invention provides a welding positioning device to solve the problem in the prior art that the plate is manually pressed down and then welded using a welding head, which not only increases the work intensity of the workers, but also poses a greater risk during welding and is prone to causing work-related injuries.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A welding positioning device comprises a guide rail and two placement plates slidably mounted on the guide rail, wherein the two placement plates are driven by a driving device to move on the guide rail; a box body is supported by a support plate above each placement plate, a pressing platform is slidably embedded in the box body, the top of the pressing platform is connected to the top of the box body by a first spring, the bottom of the pressing platform passes out of the box body, and a first guide surface is provided at one end of the pressing platform away from the support plate, and the first guide surface is inclined from top to bottom in a direction close to the support plate.

[0009] In this technical solution, it should be noted that the guide rail is a cylindrical guide rail, which is supported by a support member. The number of guide rails is specifically two, and the two guide rails are symmetrically arranged. A sealing structure is formed between the pressing table and the box body by a sealing rubber, and the position of the first guide surface is located at the part of the pressing table that passes through the outside of the box body; in this solution, when it is necessary to weld the plates to be welded, the two plates are placed on the two placement plates respectively, and the state is as follows Figure 1 As shown, after that, the two placing plates are driven to move closer to each other by the driving device. During the process of moving closer, the ends of the two plates on the two placing plates are squeezed against each other, pushing each other to move in the direction of approaching the corresponding supporting plates. During the movement of the plates, the first guide surface of the pressing platform will be squeezed. After the first guide surface is subjected to the squeezing force of the plates, the force will be transmitted to the vertical direction of the pressing platform through its own inclined structure, that is, the pressing platform will move upward and compress the first spring. The higher the compression degree of the first spring, the greater the pressure of the pressing platform on the plates. When the plates move to the lowermost position of the pressing platform, the plates are clamped and fixed by the pressing platform, and the staff can weld the two plates. In summary, in the present invention, the plates can be clamped by the provided pressing platform and the first spring. The first spring can be a high elastic coefficient spring to prevent the plates from shifting during welding and ensure stability during welding. Secondly, the present invention can automatically clamp the two plates by the pressing platform during the process of approaching each other through the provided first guide surface, without the need for staff to operate.

[0010] Preferably, an air nozzle is provided on one of the side walls of the box body, the air nozzle is connected to the box body and is located above the pressing platform, and the air outlet of the air nozzle is inclined.

[0011] In this technical solution, it should be noted that if there is dust at the welded part of the plate, it will affect the welding quality of the plate. Based on this, the present invention combines the moving mode of the pressing table and considers cleaning the dust at the welded part of the plate before welding the plate. The specific principle is: when the pressing table is squeezed upward by the plate, the gas in the box is compressed and sprayed out by the air nozzle to act on the welded part of the plate to clean the dust and improve the welding quality of the plate.

[0012] Preferably, a plurality of balls are rotatably connected to the bottom of the pressing platform.

[0013] In this technical solution, it should be noted that the spherical body is provided to reduce the sliding friction between the pressing platform and the plate.

[0014] Preferably, the pressing platform is provided with a second guide surface at one end away from the first guide surface, and the second guide surface is inclined in an opposite direction to the first guide surface, a first cavity is provided in the support plate, the height of the first cavity is greater than the thickness of the plate, and the end of the first cavity close to the pressing platform passes through the support plate, a first push block cooperating with the second guide surface is slidably embedded in the first cavity, and the end of the first push block away from the pressing platform is connected to the side wall of the first cavity through a second spring; the support plate is also provided with a second cavity parallel to the first cavity, a second push block is slidably embedded in the second cavity, one end of the second push block passes through the outside of the support plate and is connected to a push plate, and the push plate is connected to the support plate through a third spring; and also includes a linkage device, which connects the first push block and the second push block The cam is connected to the second cavity, and when the second push block moves into the second cavity, the first push block is driven to move out of the first cavity through the linkage device; a third cavity is also vertically arranged in the support plate, and the upper and lower ends of the third cavity are respectively connected to the first cavity and the second cavity, and the linkage device includes a third push block slidably embedded in the third cavity, and the bottom of the third push block is connected to the third cavity through a fourth spring; a third guide surface is provided at one end of the third push block facing the second push block, and the third guide surface is inclined from bottom to top in a direction close to the pressing platform, and the third guide surface contacts the second push block; a fourth guide surface is provided at one end of the first push block facing the third push block, and the fourth guide surface is inclined from bottom to top in a direction away from the pressing platform, and the fourth guide surface contacts the top of the third push block.

[0015] In this technical solution, it should be noted that when the plate welding is completed, the plate needs to be taken out. Since the plate is pressed by the pressing table at this time, the plate can only be taken out by loosening the pressing table. However, if the pressing table is to be loosened, the driving device needs to drive the two placement plates to move relative to each other, that is, to restore the two placement plates to their initial positions. However, since the plate is located at the bottom of the pressing table during welding, the pressure of the pressing table on the plate is the greatest at this time. If the two placement plates are to be moved relative to each other at this time, the welded plate may be pulled by the pressing table and the placement plates on both sides, which will not only cause certain wear on the plate, but also may cause damage to the driving device. Based on this, this solution arranges a first push block, a second push block and a third push block. When the plate is welded, the plate is located below the pressing table and adjacent to the push plate. When the plate welding is completed, the plate needs to be taken out. At this time, the driving device is used to drive the two placement plates to move relative to each other. The device continues to drive the two placement plates closer to each other. At this time, the plate will push the push plate, so that the push plate drives the second push block connected to it to move into the second cavity, the second push block squeezes the third guide surface, and then the third push block moves upward, and the third push block moves upward to squeeze the fourth guide surface, so that the first push block moves out of the first cavity, and the first push block squeezes the second guide surface, so that the pressing table moves upward, and then the pressing table is separated from the plate, and the pressing table no longer applies pressure to the plate. At this time, the staff can take out the welded plate; in summary, in the present invention, through the provision of the first push block, the second push block and the third push block, etc., after the plate welding is completed, it only needs to make the driving device drive the two placement plates to move a short distance in the direction of approaching each other, so as to lift the pressing table upward, separate the pressing table from the plate, and the staff can take out the welded plate.

[0016] Preferably, one end of the second push block facing the third guide surface and one end of the third push block facing the fourth guide surface are rotatably connected to rollers respectively.

[0017] In this technical solution, it should be noted that the rollers are arranged to reduce the sliding friction between each push block and the guide surface.

[0018] Preferably, the driving device comprises a support seat and a guide column, the guide column is parallel to the guide rail, the support seat is arranged on one side of the placement plate, the guide column is rotatably connected to the placement plate, two external threads are arranged on the side wall of the guide column, and the guide column is threadedly connected to the two placement plates through the two external threads respectively. The guide column is driven by a motor.

[0019] In this technical solution, it should be noted that the driving device specifically includes a guide column, two external threads and a motor. The guide column is driven to rotate by the motor, thereby causing the two placement plates threadedly connected to the guide column to move closer to or away from each other.

[0020] Preferably, a fixed plate is supported between the two placement plates through a mounting frame, the fixed plate is parallel to the placement plate, a slide groove is provided on the top of the fixed plate, one end of the slide groove in the length direction passes through the fixed plate, a moving block is slidably embedded in the slide groove, a push rod is provided on the top of the moving block, and the top of the push rod is higher than the top of the slide groove; the moving block is driven by a moving device to move along the length direction of the slide groove. The moving device includes an electric wheel, and the electric wheel is provided on the moving block.

[0021] In this technical solution, it should be noted that the fixed plate can support the welding point of the two plates. Secondly, after the plate welding is completed and the first push rod lifts the clamping table, the moving block is driven to move by the electric wheel. After the moving block moves, it drives the push rod to push the plate to the outside of the placement plate, and then pushes the plate out of the placement plate to complete automatic unloading.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In the present invention, the plate can be pressed by the provided pressing platform and the first spring. The first spring can be a high elastic coefficient spring to prevent the plate from shifting during welding and ensure the stability of the welding process. Secondly, the present invention can automatically press the two plates by the pressing platform when they are approaching each other through the provided first guide surface, without the need for the staff to operate.

[0024] 2. In the present invention, when the pressing table is squeezed by the plate and moves upward, the gas in the box is compressed and sprayed out by the gas nozzle to act on the welded part of the plate to clean the dust and improve the welding quality of the plate;

[0025] 3. In the present invention, by providing the first push block, the second push block and the third push block, after the plate welding is completed, it is only necessary to drive the two placement plates to move a short distance in the direction of approaching each other by the driving device, so that the pressing table can be pushed upward, so that the pressing table is separated from the plate, and the staff can take out the welded plate;

[0026] 4. In the present invention, after the plate welding is completed and the first push rod lifts the pressing table, the moving block is driven to move by the electric wheel. After the moving block moves, it drives the push rod to push the plate to the outside of the placement plate, and then pushes the plate out of the placement plate to complete automatic unloading.

[0044] Example 1

[0045] like Figure 1-9As shown, a welding positioning device is disclosed in an embodiment of the present invention, including a guide rail 1 and two placement plates 6 slidably mounted on the guide rail 1, the two placement plates 6 are driven by a driving device to move on the guide rail 1; a box body 4 is supported above each of the placement plates 6 by a support plate 8, a pressing platform 5 is slidably embedded in the box body 4, the top of the pressing platform 5 is connected to the top of the box body 4 by a first spring 10, the bottom of the pressing platform 5 passes through the outside of the box body 4, and a first guide surface 9 is provided at one end of the pressing platform 5 away from the support plate 8, and the first guide surface 9 is inclined from top to bottom in a direction close to the support plate 8. It should be noted that the guide rail 1 is a cylindrical guide rail 1, which is supported by a support member. The number of guide rails 1 is specifically two, and the two guide rails 1 are symmetrically arranged. A sealing structure is formed between the pressing platform 5 and the box body 4 by a sealing rubber, and the position of the first guide surface 9 is located at the part where the pressing platform 5 passes through the outside of the box body 4; in this solution, when it is necessary to weld the plates 2 to be welded, the two plates 2 are placed on the two placement plates 6 respectively, and the state is as follows Figure 1 As shown, the two placing plates 6 are then driven to move closer to each other by a driving device. During the process of moving closer, the ends of the two plates 2 on the two placing plates 6 are squeezed against each other, pushing each other to move in the direction of approaching the corresponding supporting plates 8. During the movement of the plates 2, the first guide surface 9 of the pressing platform 5 is squeezed. After the first guide surface 9 is squeezed by the plate 2, the force will be transmitted to the vertical direction of the pressing platform 5 through its own inclined structure, that is, the pressing platform 5 will move upward and compress the first spring 10. The higher the compression degree of the first spring 10, the greater the pressure of the pressing platform 5 on the plate 2. When the plate 2 moves to the lowermost position of the pressing platform 5, the plate 2 is pressed and fixed by the pressing platform 5, and the staff can weld the two plates 2; in summary, in the present invention, the plate 2 can be pressed by the setting of the pressing platform 5 and the first spring 10, and the first spring 10 can be a high elastic coefficient spring to prevent the plate 2 from shifting during the welding process and ensure the stability of the welding process; secondly, the present invention can automatically press the two plates 2 by the pressing platform 5 in the process of approaching each other through the setting of the first guide surface 9, without the need for staff to operate.

[0046] like Figure 4 As shown, in this embodiment, a gas nozzle 7 is provided on one of the side walls of the box body 4, the gas nozzle 7 is connected to the box body 4 and is located above the pressing platform 5, and the gas outlet of the gas nozzle 7 is inclined. It should be noted that if there is dust at the welding position of the plate 2, it will affect the welding quality of the plate 2. Based on this, the present invention combines the moving mode of the pressing platform 5 and considers cleaning the dust at the welding position of the plate 2 before welding the plate 2. The specific principle is: when the pressing platform 5 is squeezed and moved upward by the plate 2, the gas in the box body 4 is compressed and sprayed by the gas nozzle 7 to act on the welding position of the plate 2 to clean the dust and improve the welding quality of the plate 2.

[0047] like Figure 6 As shown, in this embodiment, a plurality of balls 11 are rotatably connected to the bottom of the pressing platform 5. It should be noted that the balls 11 are provided to reduce the sliding friction between the pressing platform 5 and the plate 2.

[0048] Example 2

[0049] like Figure 6 and Figure 7As shown, this embodiment is substantially the same as the above-mentioned embodiment, except that a second guide surface 12 is provided at one end of the pressing platform 5 away from the first guide surface 9, and the second guide surface 12 is inclined in the opposite direction to the first guide surface 9, a first cavity 18 is provided in the support plate 8, the height of the first cavity 18 is greater than the thickness of the plate 2, and the end of the first cavity 18 close to the pressing platform 5 passes through the support plate 8, a first push block 19 cooperating with the second guide surface 12 is slidably embedded in the first cavity 18, and the end of the first push block 19 away from the pressing platform 5 is connected to the side wall of the first cavity 18 through a second spring 20; a second cavity 15 parallel to the first cavity 18 is also provided in the support plate 8, a second push block 14 is slidably embedded in the second cavity 15, one end of the second push block 14 passes through the outside of the support plate 8 and is connected to a push plate 13, and the push plate 13 is connected to the support plate 8 through a third spring 32; and a linkage device is also included, which connects the first push block 19 to the support plate 8. The block 19 is connected with the second push block 14. When the second push block 14 moves into the second cavity 15, the first push block 19 is driven to move out of the first cavity 18 through the linkage device; a third cavity 16 is also vertically arranged in the support plate 8, and the upper and lower ends of the third cavity 16 are respectively connected with the first cavity 18 and the second cavity 15, and the linkage device includes a third push block 17 slidably embedded in the third cavity 16, and the bottom of the third push block 17 is connected to the third cavity 16 through a fourth spring 23; a third guide surface 21 is provided at one end of the third push block 17 facing the second push block 14, and the third guide surface 21 is inclined from bottom to top along the direction close to the pressing platform 5, and the third guide surface 21 contacts the second push block 14; a fourth guide surface 22 is provided at one end of the first push block 19 facing the third push block 17, and the fourth guide surface 22 is inclined from bottom to top along the direction away from the pressing platform 5, and the fourth guide surface 22 contacts the top of the third push block 17.When the plate 2 is welded, the plate 2 needs to be taken out. Since the plate 2 is clamped by the clamping platform 5 at this time, the plate 2 can only be taken out by loosening the clamping platform 5. However, if the clamping platform 5 is to be loosened, the driving device needs to drive the two placement plates 6 to move relative to each other, that is, the two placement plates 6 return to their initial positions. However, since the plate 2 is located at the bottom of the clamping platform 5 during welding, the pressure of the clamping platform 5 on the plate 2 is the greatest at this time. If the two placement plates 6 are to be moved relative to each other at this time, the welded plate 2 may be pulled by the clamping platform 5 and the placement plates 6 on both sides, which will not only cause certain wear on the plate 2, but also may cause damage to the driving device. Based on this, the present scheme provides a first push block 19, a second push block 14 and a third push block 17. When the plate 2 is welded, the plate 2 is located below the clamping platform 5 and is adjacent to the push plate 13. When the plate 2 is welded, the plate 2 needs to be taken out. At this time, the driving device continues to drive the two placement plates 6 approach each other, at this time, the plate 2 will push the push plate 13, so that the push plate 13 drives the second push block 14 connected thereto to move into the second cavity 15, the second push block 14 squeezes the third guide surface 21, and then the third push block 17 moves upward, the third push block 17 moves upward and squeezes the fourth guide surface 22, so that the first push block 19 moves out of the first cavity 18, the first push block 19 squeezes the second guide surface 12, so that the pressing table 5 moves upward, and then the pressing table 5 is separated from the plate 2, and the pressing table 5 no longer applies pressure to the plate 2, at this time, the staff can take out the welded plate 2; in summary, in the present invention, by setting the first push block 19, the second push block 14 and the third push block 17, after the plate 2 is welded, it only needs to make the driving device drive the two placing plates 6 to move a short distance in the direction of approaching each other, so as to push the pressing table 5 upward, so that the pressing table 5 is separated from the plate 2, and the staff can take out the welded plate 2.

[0050] like Figure 6 As shown, in this embodiment, one end of the second push block 14 facing the third guide surface 21 and one end of the third push block 17 facing the fourth guide surface 22 are rotatably connected to rollers. It should be noted that the rollers are provided to reduce the sliding friction between each push block and the guide surface.

[0051] Example 3

[0052] like Figure 8As shown, this embodiment is substantially the same as the above embodiment, except that the driving device includes a support seat 27 and a guide column 24, the guide column 24 is parallel to the guide rail 1, the support seat 27 is arranged on one side of the placement plate 6, the guide column 24 is rotatably connected to the placement plate 6, two external threads 26 are arranged on the side wall of the guide column 24, and the guide column 24 is threadedly connected to the two placement plates 6 through the two external threads 26 respectively. The guide column 24 is driven by a motor 25. It should be noted that the driving device specifically includes a guide column 24, two external threads 26 and a motor 25, and the guide column 24 is driven to rotate by the motor 25, so that the two placement plates 6 threadedly connected to the guide column 24 are moved closer to each other or away from each other.

[0053] like Fig. 9 As shown, a fixed plate 31 is supported between the two placement plates 6 by the mounting frame 3. The fixed plate 31 is parallel to the placement plate 6. A slide groove 29 is provided on the top of the fixed plate 31. One end of the slide groove 29 in the length direction passes through the fixed plate 31. A moving block 28 is slidably embedded in the slide groove 29. A push rod 30 is provided on the top of the moving block 28. The top of the push rod 30 is higher than the top of the slide groove 29. The moving block 28 is driven by a moving device to move along the length direction of the slide groove 29. The moving device includes an electric wheel, which is arranged on the moving block 28. It should be noted that after the welding of the plate 2 is completed and the first push rod 30 lifts the pressing table 5, the moving block 28 is driven to move by the electric wheel. After the moving block 28 moves, it drives the push rod 30 to push the plate 2 to move to the outside of the placement plate 6, and then pushes the plate 2 out of the placement plate 6 to complete the automatic discharge.

[0054] The principle of the present invention is:

[0055] When the plates 2 to be welded need to be welded, the two plates 2 are placed on the two placement plates 6 respectively. Figure 1 and Figure 4As shown, thereafter, the guide column 24 is driven to rotate by the motor 25, so that the two placement plates 6 threadedly connected with the guide column 24 are brought closer to each other. During the process of bringing closer, the ends of the two plates 2 on the two placement plates 6 are squeezed against each other, pushing each other to move in the direction of approaching the corresponding support plate 8. During the movement of the plates 2, the first guide surface 9 of the clamping platform 5 will be squeezed. After the first guide surface 9 is squeezed by the plate 2, the force will be transmitted to the vertical direction of the clamping platform 5 through its own inclined structure, that is, the clamping platform 5 will move upward. When the clamping platform 5 is squeezed and moved upward by the plate 2, the gas in the box 4 is compressed and sprayed by the air nozzle 7 to act on the welded part of the plate 2 to clean the dust and improve the welding quality of the plate 2. The clamping platform 5 moves and compresses the first spring 10. The higher the compression degree of the first spring 10, the greater the pressure of the clamping platform 5 on the plate 2. When the plate 2 moves to the lowermost position of the clamping platform 5, the plate 2 is clamped and fixed by the clamping platform 5, and the staff can weld the two plates 2. At this time, the state of the plate 2 after being clamped is as shown in Figure 5 shown.

[0056] After the welding of the plate 2 is completed, the plate 2 needs to be taken out. At this time, the driving device continues to drive the two placement plates 6 to move closer to each other. At this time, the plate 2 will push the push plate 13, so that the push plate 13 drives the second push block 14 connected thereto to move into the second cavity 15, and the second push block 14 squeezes the third guide surface 21, thereby causing the third push block 17 to move upward. The third push block 17 moves upward and squeezes the fourth guide surface 22, so that the first push block 19 moves out of the first cavity 18, and the first push block 19 squeezes the second guide surface 12, so that the pressing table 5 moves upward, thereby separating the pressing table 5 from the plate 2, and the pressing table 5 no longer applies pressure to the plate 2. At this time, the state is as follows: Figure 7 As shown, at this time, the moving block 28 is driven to move by the electric wheel.
