Description

Technical Field

[0001] This invention relates to the field of metal welding technology, and more specifically to a welding system and welding process. Background Technology

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Modern welding has many energy sources, including gas flame, electric arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be carried out in a variety of environments, such as in the field, underwater and in space. No matter where it is, welding can pose dangers to the operator, so appropriate protective measures must be taken when welding. The injuries that welding may cause to the human body include burns, electric shock, vision impairment, inhalation of toxic gases, excessive exposure to ultraviolet rays, etc. And current technology cannot fix circular plates and rings of different thicknesses together by welding. Summary of the Invention

[0003] The purpose of this invention is to provide a welding system and welding process, which can fix circular plates and rings of different thicknesses together by welding.

[0004] A welding system includes a support table and a support circular plate fixedly connected to the support table. Multiple lifting columns are slidably connected to the support table, and the multiple lifting columns are grouped in pairs. Each pair of lifting columns is fixedly connected to a side support plate. Each side support plate is slidably connected to a compression wedge plate. Each compression wedge plate is fixedly connected to a telescopic rod I. Each telescopic rod I is fixedly connected to a compression frame plate. Each compression frame plate is fixedly connected to the multiple side support plates.

[0005] Furthermore, a linkage support plate is fixedly connected to the lower part of each of the two sets of lifting slide columns.

[0006] Furthermore, a telescopic rod II is fixedly connected to the linkage support plate, and the telescopic rod II is fixedly connected to the bottom of the supporting horizontal table plate.

[0007] Furthermore, multiple supporting legs are evenly and fixedly connected below the supporting horizontal table.

[0008] Furthermore, the supporting horizontal table is fixedly connected to a supporting plate, a supporting rotating plate is rotatably connected to the supporting plate, a hollow square cavity is fixedly connected to the supporting rotating plate, a fixed supporting square rod is slidably connected inside the hollow square cavity, a horizontal sliding plate is fixedly connected to the fixed supporting square rod, and an extension sliding plate is slidably connected to both ends of the horizontal sliding plate. A telescopic rod III is fixedly connected to the supporting rotating plate, and the telescopic rod III is located inside the hollow square cavity and fixedly connected to the fixed supporting square rod.

[0009] Furthermore, a bidirectional lead screw is rotatably connected to the fixed support rod, and the two ends of the bidirectional lead screw are respectively connected to two extended sliding plates through threaded transmission.

[0010] Furthermore, both of the extended sliding plates are fixedly connected with a support cavity.

[0011] Furthermore, a limiting slide cavity is rotatably connected to the transverse slide plate, a convex slide rod is slidably connected inside the limiting slide cavity, a pressing circular plate is fixedly connected to the convex slide rod, and a spring is placed between the limiting slide cavity and the convex slide rod.

[0013] Furthermore, the welding process of the aforementioned welding system includes the following steps:

[0014] Step 1: Place the welded circular plate onto the support circular plate, activate multiple telescopic rods I to drive multiple extrusion wedges to move inward, extruding the welded circular plate to achieve centering of the welded circular plate;

[0015] Step 2: After centering is completed, multiple extrusion wedges will be retracted. Then, the welded outer ring will be placed on multiple side support plates, and multiple sets of two lifting slides will drive the multiple side support plates to rise and fall, ensuring that the welded circular plate is flush with the upper surface of the welded outer ring.

[0016] Step 3: After leveling, activate multiple telescopic rods I to drive multiple extrusion wedges to move inward, thereby extruding the welded outer ring and completing the centering and fixing of the welded outer ring.

[0031] The following is in conjunction with the appendix Figure 1-10 The present invention will be described in further detail below.

[0032] The following is in conjunction with the appendix Figure 1-5 Detailed description: A welding system includes a supporting horizontal table 101 and a support circular plate 102 fixedly connected to the supporting horizontal table 101 by welding. Multiple lifting columns 103 are slidably connected to the supporting horizontal table 101 through circular holes. The multiple lifting columns 103 are grouped in pairs. Each pair of lifting columns 103 is fixedly connected to a side support plate 104 by welding. Each side support plate 104 is slidably connected to a pressing wedge plate 105 through a sliding groove. Each pressing wedge plate 105 is fixedly connected to a telescopic rod 1106 through a flange plate. Each telescopic rod 1106 is fixedly connected to a pressing frame plate 107 through a flange plate. The pressing frame plates 107 are respectively fixedly connected to the multiple side support plates 104 by welding.

[0033] Furthermore, the supporting horizontal table plate 101 serves as a load-bearing connection, providing a fixed space for the intermediate circular plate 102. The intermediate circular plate 102 provides a space for the welded circular plate. Multiple friction grooves are provided on the intermediate circular plate 102 to increase the friction between the welded circular plate and the intermediate circular plate 102, preventing the welded circular plate from moving freely on the intermediate circular plate 102. Multiple sets of two lifting slide columns 103 provide a fixed space for multiple side support plates 104 and limit their movement, ensuring that the side support plates 104 can only slide up and down. The multiple side support plates 104 provide a fixed space for the outer ring to be welded. The outer ring can be placed on the multiple side support plates 104. At this time, the lifting mechanism can drive the multiple sets of two lifting slide columns 103 to rise and fall, thereby changing the height of the multiple side support plates 104 and ensuring that the upper surface of the welded circular plate and the welded outer ring are aligned. The surface is flat, and welding is achieved at the contact port of the ring, ultimately fixing the welded circular plate and the welded outer ring together. Multiple extrusion wedges 105 can be used to center the welded circular plate and the welded outer ring, and can also be used to extrude and fix the outer ring at the outer end. Multiple telescopic rods I106 can drive multiple extrusion wedges 105 to move, thereby changing the position of multiple extrusion wedges 105 to make contact with the welded circular plate and the welded outer ring. Multiple telescopic rods I106 are connected to the same power line through a telescopic switch to ensure that multiple telescopic rods I106 can be started at the same time, thereby simultaneously driving multiple extrusion wedges 105 to slide laterally. Multiple extrusion frame plates 107 can provide fixed space for multiple telescopic rods I106, ensuring that when multiple telescopic rods I106 are started, the rear ends of multiple telescopic rods I106 will not move, thereby driving multiple extrusion wedges 105 to slide laterally.

[0034] The welded circular plate is placed on the intermediate support circular plate 102. Multiple telescopic rods I106 are activated to drive multiple extrusion wedges 105 to move inward, extruding the welded circular plate and centering it. After centering, the extrusion wedges 105 are retracted. Then, the welded outer ring is placed on multiple side support plates 104, and multiple sets of two lifting slides 103 are used to lift the side support plates 104 to ensure that the welded circular plate and the upper surface of the welded outer ring are level. After leveling, multiple telescopic rods I106 are activated to drive multiple extrusion wedges 105 to move inward, extruding the welded outer ring and centering and fixing it. Then, a welding torch is used to weld the connection between the welded circular plate and the welded outer ring, fixing them together. Finally, the weld joint is ground to ensure the flatness of the weld joint between the welded circular plate and the welded outer ring.

[0035] The following is in conjunction with the appendix Figure 1 , 2As detailed in section 4, multiple sets of two lifting slide columns 103 are fixedly connected to a linkage support plate 201 by welding below them.

[0036] Furthermore, by using the linkage support plate 201 to fix multiple sets of two lifting slide columns 103 together, moving the linkage support plate 201 can drive multiple sets of two lifting slide columns 103 to rise and fall simultaneously. Finally, multiple side support plates 104 can also rise and fall simultaneously, thereby ensuring the flatness of the welded outer ring and further enhancing the welding effect on the circular plate.

[0037] The following is in conjunction with the appendix Figure 1 , 2 As detailed in section 4, a telescopic rod II301 is fixedly connected to the linkage support plate 201 via a flange plate, and the telescopic rod II301 is fixedly connected to the underside of the supporting horizontal table plate 101 via a flange plate.

[0038] Furthermore, after activating the telescopic rod II301, the linkage support plate 201 can be raised and lowered, thereby changing the height of multiple side support plates 104 to ensure that the welding circular plate is flush with the upper surface of the welding outer ring, further enhancing the welding effect on the circular plate.

[0039] According to the instruction manual Figure 1-3 In detail, multiple supporting legs 401 are uniformly and fixedly connected to the underside of the supporting horizontal table 101 by welding.

[0040] Furthermore, by using multiple supporting legs 401, the supporting horizontal table 101 can be placed firmly and stably on the ground, and the supporting horizontal table 101 can also be supported to provide space for the lifting and lowering of the linkage plate 201. After that, the linkage plate 201 can slide up and down freely to ensure that the upper surface of the welding round plate is flush with the upper surface of the welding outer ring.

[0041] According to the instruction manual Figure 1 and 6 -9 Detailed Description: A support plate 501 is fixedly connected to the supporting horizontal table 101 by welding. A supporting rotating plate 502 is rotatably connected to the supporting plate 501 through a round hole. A hollow square cavity 503 is fixedly connected to the supporting rotating plate 502 by welding. A fixed supporting square rod 504 is slidably connected to the hollow square cavity 503 through a square opening. A horizontal sliding plate 505 is fixedly connected to the fixed supporting square rod 504 by welding. Both ends of the horizontal sliding plate 505 are slidably connected to an extension sliding plate 506 through a straight cavity. A telescopic rod III 507 is fixedly connected to the supporting rotating plate 502 through a flange plate. The telescopic rod III 507 is located inside the hollow square cavity 503 and is fixedly connected to the fixed supporting square rod 504 through a flange plate.

[0042] Furthermore, the supporting horizontal table 101 provides support and space for the rotating plate 502 to rotate. The rotating plate 502 provides a fixed space for the hollow square cavity 503, which in turn provides a sliding space for the fixed supporting rod 504. The fixed supporting rod 504 provides a fixed space for the horizontal sliding plate 505. Activating the telescopic rod III 507 causes the fixed supporting rod 504 to rise and fall within the hollow square cavity 503, thereby changing the height of the horizontal sliding plate 505. The horizontal sliding plate 505 provides sliding space for the two extended sliding plates 506, allowing the welding torch and grinding plate to be fixed on them respectively. After the welding round plate and welding outer ring are placed, activating the telescopic rod III 507 causes the fixed supporting rod 504 to move downwards, thus changing the height of the horizontal sliding plate 505. The sliding plate 505 and the two extended sliding plates 506 move downwards, so that the welding gun and the grinding plate are in contact with the welding round plate and the welding outer ring. Then, the two extended sliding plates 506 are slid to change the position of the welding gun and the grinding plate, ensuring that the welding gun and the grinding plate are directly above the connection ring between the welding round plate and the welding outer ring. The welding gun and the grinding plate are started, and then the supporting rotating plate 502 is rotated, so that the welding gun and the grinding plate are in contact with the connection ring between the welding round plate and the welding outer ring while rotating, thus achieving welding and grinding treatment of the connection ring between the welding round plate and the welding outer ring. When the supporting rotating plate 502 rotates, the telescopic rod III 507 will also be started to extend, starting the feeding purpose, ensuring that when the welding rod is consumed, the welding rod will also move downwards, ensuring that the welding rod and the grinding plate are always in contact with the connection ring between the welding round plate and the welding outer ring.

[0043] According to the instruction manual Figure 1 , 6 Detailed descriptions of sections 7 and 9: The fixed support rod 504 is rotatably connected to a bidirectional lead screw 601 through a round hole. The two ends of the bidirectional lead screw 601 are respectively connected to two extended sliding plates 506 through threaded transmission.

[0044] Furthermore, the threads at both ends of the bidirectional lead screw 601 rotate in opposite directions. Rotating the bidirectional lead screw 601 will drive the two extension slide plates 506 to slide inward or outward simultaneously, thereby changing the position of the two extension slide plates 506. This ensures that the welding gun and the grinding plate are both located directly above the connection ring between the welding round plate and the welding outer ring, and enables welding and grinding of the connection ring.

[0045] According to the instruction manual Figure 1 , 6 Detailed descriptions of sections 7 and 9: Both of the extended slide plates 506 are fixedly connected to a support cavity 701 by welding.

[0046] Furthermore, the welding torch and the grinding plate can be fixed in the two fixed support cavities 701 respectively.

[0047] According to the instruction manual Figure 1 , 6Detailed descriptions of sections 7, 9, and 10: The horizontal sliding plate 505 is rotatably connected to a limiting slide cavity 801 via a bearing seat. A convex round slide rod 802 is slidably connected to the limiting slide cavity 801 via a straight cavity. An extrusion round plate 803 is fixedly connected to the convex round slide rod 802 by welding. A spring 804 is placed between the limiting slide cavity 801 and the convex round slide rod 802.

[0048] Furthermore, the limiting slide cavity 801 provides sliding space for the convex slide rod 802, while the convex slide rod 802 provides fixed space for the extrusion plate 803. The extrusion plate 803 can be used to extrude the welding plate and fix it. The elastic force generated by the spring 804 can act on the convex slide rod 802, thereby ensuring that the extrusion plate 803 can contact the welding plate. There is also a buffer space, so that when the horizontal slide plate 505 continues to move downward, the extrusion plate 803 will not damage the welding plate.

[0049] According to the instruction manual Figure 1 , 6 As detailed in section 7, a reduction motor 901 is fixedly connected to the support plate 501 via a flange plate, and the output shaft of the reduction motor 901 is fixedly connected to the supporting rotating plate 502 via a keyway and a snap ring.

[0050] Furthermore, after starting the geared motor 901, the supporting rotating plate 502 can be driven to rotate, thereby enabling the welding gun and grinding plate to rotate while contacting the welding circular plate and the welding outer ring connection ring.

[0051] The welding process of the aforementioned welding system includes the following steps:

[0052] Step 1: Place the welded circular plate onto the intermediate support circular plate 102, and activate multiple telescopic rods I106 to drive multiple extrusion wedges 105 to move inward, extruding the welded circular plate to achieve centering of the welded circular plate.

[0053] Step 2: After centering is completed, multiple extrusion wedges 105 will be retracted. Then, the welded outer ring will be placed on multiple side support plates 104, and multiple sets of two lifting slides 103 will drive the multiple side support plates 104 to rise and fall, ensuring that the welded circular plate is level with the upper surface of the welded outer ring.

[0054] Step 3: After leveling, activate multiple telescopic rods I106 to drive multiple extrusion wedges 105 to move inward, thereby extruding the welded outer ring and completing the centering and fixing of the welded outer ring.

[0055] Step 4: Then, use a welding torch to weld the connecting ring between the welded circular plate and the welded outer ring, thus fixing the welded circular plate and the welded outer ring together.

[0056] Step 5: Finally, grind the weld joint to ensure the flatness of the welded circular plate and the welded outer ring.
