Description

Technical Field

[0001] The invention belongs to the technical field of parts welding, in particular to a fan shell welding device. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken during welding. The possible injuries to the human body caused by welding include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] In the prior art, when welding fan parts, operators are required to wear protective masks, protective gloves and other equipment to operate. When welding the fan casing, the ribs must first be welded to the circular plate, and then the welded ribs must be shaped, and finally the shaped ribs must be welded to the frame. This is because when welding the ribs of the fan casing, the welding position may deviate due to the impact of the welding gun on the welding point and the instability of manual fixation. During manual control, even if proper protection is provided, there may be other forms of accidental injury to the operator. The device of the present invention, through the cooperation of the fixing mechanism, has a better effect of fixing the ribs and the frame. During the welding process, there is no need for manual operation to control the ribs and the frame, which greatly reduces the risk of personal injury.

[0004] To this end: the present invention provides a fan casing welding device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

Before the first step of welding the ribs of the fan casing, the first step is to control the rotation of the fixing column. The rotation of the fixing column controls the downward movement of the support plate. When the support plate is downward, the bottom of the supporting chassis is stressed, causing the lifting column to control the load-bearing part to rise. At this time, a certain distance is generated between the operating panel and the load-bearing part, preparing for the first step of welding.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figure 1 to Figure 2 As shown, a fan casing welding device according to an embodiment of the present invention comprises a welding shell 1, a support frame 100 is fixedly installed on the outer wall of the welding shell 1, and a fixing mechanism 200 and an adjusting mechanism 300 are arranged outside the welding shell 1;

[0037] The adjustment mechanism 300 includes a fixed column 301, one end of which is threadedly connected to a support plate 302, an output end of the support plate 302 is provided with a support chassis 303, an outer wall of the support chassis 303 is provided with an operating panel 304, an inner part of the operating panel 304 is provided with a lifting column 305, and one end of the lifting column 305 is fixedly connected to a load-bearing member 306;

[0038] During operation, the welding shell 1 and the support frame 100 provide a platform for the welding of the fan housing. The fixing mechanism 200 is used to fix the frame and the ribs when welding the fan housing, and to shape the outer wall of the fan to meet standard specifications. The adjustment mechanism 300 is used to adjust the position of the welding gun and control the transportation and transfer of the fan housing. Before the first step of welding the ribs of the fan housing, the fixing column 301 must first be controlled to rotate. The fixing column 301 rotates to control the support plate 302 to move downward. When the support plate 302 moves downward, the bottom of the supporting chassis 303 is stressed, causing the lifting column 305 to control the load-bearing member 306 to rise. At this time, a certain distance is generated between the operating panel 304 and the load-bearing member 306, preparing for the first step of welding. The reverse movement of the support plate 302 and the load-bearing member 306 achieves the purpose of laying a good foundation for the welding and shaping of the fan housing.

[0039] like Figure 1 and Figure 7 As shown, an angle adjustment member 307 is provided at the bottom of the operating panel 304, a slide groove 308 is provided on the outer wall of the angle adjustment member 307, a starter member 309 is provided on the outer wall of the support plate 302, a toggle plate 310 is rotatably connected to the outer wall of the starter member 309, and the other end of the toggle plate 310 is slidably connected to the slide groove 308;

[0040] During operation, when the fan housing performs the first step of rib welding, the ribs need to be welded to the fan parts one by one, so the operation panel 304 needs to be controlled to rotate at a certain angle during the welding process, and the starter 309 rotates to control the toggle plate 310 to rotate, and the other end of the toggle plate 310 rotates along the slide groove 308 of the angle adjustment member 307. Thus, the operation panel 304 is controlled by the toggle plate 310 according to the angle distribution of the angle adjustment member 307, thereby playing a role in accurately controlling the angle adjustment of the operation panel 304 during the rib welding.

[0041] like Figures 1 to 4 As shown, the outer wall of the support frame 100 is provided with a main control column 101, and the outer walls of the main control column 101 are respectively provided with a first control member 102 and a second control member 103, and the outer walls of the first control member 102 and the second control member 103 are both provided with a displacement groove 104, and the inner walls of the displacement groove 104 are both slidably provided with a slider 105, and the inner wall of the second control member 103 is provided with a connecting column 106, and the interior of the main control column 101 is provided with a central column 107, and one end of the central column 107 is fixedly connected to the fixed column 301;

[0042] During operation, when welding the ribs, the slider 105 slides inside the displacement groove 104 on the first control member 102 until it reaches a designated position. When the second step of welding the ribs and the frame is required, the slider 105 on the second control member 103 slides inside the displacement groove 104 until it reaches a designated position. By moving the slider 105 in the first step and the second step, the height of the welding gun can be adjusted during welding.

[0043] like Figures 3 to 5 As shown, the outer wall of one of the sliders 105 is provided with a first welding plate 311, the outer wall of the other slider 105 is provided with a second welding plate 312, the inner walls of the first welding plate 311 and the second welding plate 312 are both provided with eccentric wheels 313, the inner walls of the first welding plate 311 and the second welding plate 312 are both provided with left-shift wheels 314, the inner walls of the first welding plate 311 and the second welding plate 312 are both provided with right-shift wheels 315, and the teeth of the eccentric wheels 313 are respectively meshed with the teeth of the left-shift wheels 314 and the right-shift wheels 315;

[0044] During operation, when the umbrella ribs are welded, the eccentric wheel 313 inside the first welding plate 311 rotates. Because the eccentric wheel 313 is meshed with the left-moving wheel 314, the eccentric wheel 313 controls the left-moving wheel 314 to rotate, causing the entire body to be displaced to the left by a certain amount. Because the eccentric wheel 313 is meshed with the right-moving wheel 315, the eccentric wheel 313 controls the right-moving wheel 315, causing the entire body to be displaced to the right by a certain amount. In this way, the entire body will reciprocate left and right. In the second stage of welding, the mechanical operation is consistent with the first stage. Through the operation of the eccentric wheel 313, the effect of controlling the entire body to move left and right is achieved.

[0045] like Figures 3 to 6 As shown, the outer walls of the first welding plate 311 and the second welding plate 312 are both provided with a rotating cylinder 316, the output shaft of the rotating cylinder 316 is fixedly connected to the eccentric wheel 313, the outer walls of the left-moving wheel 314 and the right-moving wheel 315 are provided with a moving block 317, and the outer wall of the moving block 317 is fixedly installed with a welding piece 318;

[0046] During operation, when the welding process is being carried out, the welding piece 318 needs to move back and forth at the place where the ribs and the frame need to be welded, and the rotating cylinder 316 starts to control the rotation of the eccentric wheel 313. The eccentric wheel 313 achieves the effect of controlling the reciprocating movement of the displacement block through the cooperation of the left-moving wheel 314 and the right-moving wheel 315, and finally the displacement block is able to control the welding piece 318 to perform welding.

[0047] like Figure 4As shown, the fixing mechanism 200 includes a fixing plate 201, a plurality of slots 202 are formed on the outer wall of the fixing plate 201, a lifting rod 203 is fixedly connected to the outer wall of the fixing plate 201, a first transmission member 204 is transmission-connected between the lifting rod 203 and the outer wall of the connecting column 106, and a second transmission member 205 is transmission-connected between the central column 107 and the outer wall of the connecting column 106;

[0048] During operation, when the first step of welding the ribs is completed, the second step of welding the ribs and the frame needs to be performed. At this time, the center column 107 rotates to control the connection column 106 to rotate through the second transmission member 205, and the connection column 106 controls the rotation of the lifting rod 203 through the first transmission member 204. The lifting rod 203 controls the fixing plate 201 to move downward to press the center of the ribs until it contacts the operating panel 304 and stops. The outer wall of the fixing plate 201 has a plurality of slots 202, and these slots 202 just clamp each frame of the ribs. The control of the ribs by the slots 202 has a better effect of fixing the ribs, and the subsequent welding of the ribs and the frame will not have the problem of misaligned welding points.

[0049] like Figures 8 to 11 As shown, the outer wall of the operating panel 304 is evenly arranged with hinges 206, the outer wall of the hinge 206 is rotatably connected with a frame clamp 207, and the outer walls of the frame clamp 207 are fixedly installed with rib clamps 208, the outer wall of the rib clamp 208 is rotatably connected with a first linkage plate 209, the outer wall of the first linkage plate 209 is rotatably connected with a first linkage column 210, the outer wall of the first linkage column 210 is rotatably connected with a second linkage plate 211, the outer wall of the second linkage plate 211 is rotatably connected with a second linkage column 212, the outer wall of the second linkage column 212 is rotatably connected with a third linkage plate 213, the outer wall of the third linkage plate 213 is rotatably connected to the outer wall of another frame clamp 207, and a stretching handle 214 is fixedly installed on the outer wall of one of the frame clamps 207;

[0050] During operation, when the frame and the ribs are welded, the stretching handle 214 is toggled to control the frame clamp 207 to rotate along the hinge 206. At this time, the rib clamp 208 rotates together with the frame clamp 207. The rib clamp 208 controls the first linkage plate 209 to rotate. The first linkage plate 209 controls the second linkage plate 211 to rotate through the first linkage column 210. The second linkage plate 211 controls the third linkage plate 213 to rotate through the second linkage column 212. The third linkage plate 213 controls the next rib clamp 208 to rotate. By analogy, when the stretching handle 214 is toggled, the frame clamp 207 and the rib clamp 208 will rotate in sequence like dominoes and finally all flip over to fix the ribs and the frame. Through the cooperation of the linkage rod and the linkage column, the control clamps can be flipped in sequence.

[0051] like Fig.12As shown, a motor 108 is disposed inside the welding housing 1, and the output shaft of the motor 108 is fixedly connected to the starter 309. A plurality of limit rods 109 are disposed on the outer wall of the welding housing 1, and one end of the limit rod 109 is fixedly connected to the limit block 110;

[0052] During operation, the motor 108 is first started, and the output shaft of the motor 108 controls the starter 309 to rotate, and the motor 108 provides power for subsequent operations.

[0053] like Fig.12 As shown, the other end of the lifting column 305 is fixedly connected to the limiting member 111, the teeth of the limiting member 111 are meshed with the teeth of the limiting block 110, and the other end of the limiting rod 109 is drivingly connected to the output shaft of the motor 108 through an assisting member 112;

[0054] During operation, the motor 108 controls the rotation of the limit rod 109 through the auxiliary part 112, and the limit rod 109 controls the rotation of the limit block 110. Because the limit block 110 is engaged with the limit member 111, the limit member 111 also rotates accordingly. The limit member 111 controls the load-bearing member 306 to rise, causing the fan casing that has finally been welded to be separated from the operating panel 304.

[0055] like Figure 1 As shown, a skeleton tube 113 is fixedly mounted on the outer wall of the welding shell 1, and a hooking member 114 is provided on the outer wall of the support frame 100;

[0056] During operation, the skeleton tube 113 provides material for the fan casing, and the support frame 100 is provided with a hooking piece 114, which needs to be taken out after the fan casing is welded to complete the installation of the fan and reserve a position for subsequent welding.

[0057] Working principle: The welding shell 1 and the support frame 100 provide a platform for welding the fan casing. The fixing mechanism 200 is used to fix the frame and the ribs when welding the fan casing, and to shape the outer wall of the fan to meet standard specifications. The adjustment mechanism 300 is used to adjust the position of the welding gun and control the transportation and transfer of the fan casing. The frame tube 113 provides materials for the fan casing. First, the motor 108 is started, and the output shaft of the motor 108 controls the rotation of the starting member 309. Before the first step of welding the ribs of the fan casing, the fixing column 301 must be controlled to rotate. The fixing column 301 rotates to control the support plate 302 to move downward. When the support plate 302 moves downward, the bottom of the supporting chassis 303 is subjected to force, causing the lifting column 305 to control the load-bearing member 306 to rise. At this time, a certain distance is generated between the operating disk 304 and the load-bearing member 306, and preparation is made for the first step of welding. When the fan shell performs the first step of rib welding, the ribs need to be welded to the parts of the fan one by one, so the operation disk 304 needs to be controlled to rotate at a certain angle during the welding process. The starter 309 rotates to control the toggle plate 310 to rotate, and the other end of the toggle plate 310 rotates along the slide groove 308 of the angle adjustment member 307. Thus, the operating disk 304 is controlled by the toggle plate 310 according to the angle distribution of the angle adjustment member 307, so as to accurately control the angle adjustment of the operating disk 304 during the rib welding. When welding the ribs, the slider 105 slides inside the displacement groove 104 on the first control member 102. The first welding plate 311 is welded to the frame and the ribs, and the eccentric wheel 313 is rotated to the specified position. When the second process of welding the ribs and the frame is required, the slider 105 on the second control member 103 slides in the displacement groove 104 to the specified position. By moving the slider 105 in the first process and the second process, the height of the welding gun can be adjusted during welding. The eccentric wheel 313 inside the first welding plate 311 rotates. Because the eccentric wheel 313 is meshed with the left-moving wheel 314, the eccentric wheel 313 controls the left-moving wheel 314 to rotate, causing the whole to be displaced to the left by a certain amount. Because the eccentric wheel 313 is meshed with the right-moving wheel 315, the eccentric wheel 313 controls the right-moving wheel 315 to cause the whole to be displaced to the right by a certain amount. In this way, the whole will move back and forth left and right. In the second stage of welding, the mechanical The operation is consistent with the first stage. The operation of the eccentric wheel 313 plays an effect of controlling the overall left and right movement. During the welding process, the welding piece 318 needs to move forward and backward at the place where the ribs and the frame need to be welded. The rotary cylinder 316 starts to control the rotation of the eccentric wheel 313. The eccentric wheel 313 achieves the effect of controlling the reciprocating movement of the displacement block through the cooperation of the left-moving wheel 314 and the right-moving wheel 315. Finally, the displacement block controls the welding piece 318 to weld. When the first step of rib welding is completed, the second step of welding the ribs and the frame needs to be carried out. At this time, the central column 107 rotates to control the rotation of the connecting column 106 through the second transmission member 205, and the connecting column 106 controls the rotation of the lifting rod 203 through the first transmission member 204.The lifting rod 203 controls the fixing plate 201 to move downward to press the center of the umbrella rib until it contacts the operating plate 304 and stops. The outer wall of the fixing plate 201 has a plurality of slots 202, which just clamp each frame of the umbrella rib. The control of the umbrella rib by the slots 202 has a better effect of fixing the umbrella rib, and there will be no misalignment of the welding points when the umbrella ribs and the frame are welded later. When the frame and the umbrella rib are welded, the stretching handle 214 is turned to control the frame clamp 207 to rotate along the hinge 206. At this time, the umbrella rib clamp 208 rotates together with the frame clamp 207. The umbrella rib clamp 208 controls the first linkage plate 209 to rotate. The first linkage plate 209 controls the second linkage plate 211 to rotate through the first linkage column 210. The second linkage plate 211 controls the rotation of the second linkage column 212. The third linkage plate 213 rotates, and the third linkage plate 213 controls the next umbrella rib clamp 208 to rotate. By analogy, when the stretching handle 214 is turned, the frame clamp 207 and the umbrella rib clamp 208 will rotate in sequence like dominoes and finally flip over to fix the umbrella rib and the frame. Through the cooperation of the linkage rod and the linkage column, the effect of controlling the clamps to flip in sequence is achieved. The motor 108 controls the rotation of the limit rod 109 through the auxiliary member 112, and the limit rod 109 controls the rotation of the limit block 110. Because the limit block 110 is engaged with the limit member 111, the limit member 111 also rotates accordingly. The limit member 111 controls the load-bearing member 306 to rise, so that the fan housing that is finally welded is separated from the operating panel 304. When the fan housing is welded, it needs to be taken out to complete the installation of the fan and leave a position for subsequent welding.
