Description

Technical Field

[0001] The invention relates to the field of welding devices, in particular to a condensate storage tank processing welding device. Background Art

[0002] A condensate storage tank is a device used to store condensate. Condensate storage tanks are usually made of metal materials and have sufficient strength and corrosion resistance to withstand the pressure of the internal liquid and the influence of the external environment. A small condensate storage tank is welded from two upper and lower cylinders. The upper side of the upper half of the small condensate storage tank is connected to the inlet and outlet of the condensate.

[0003] At present, when two cylinders of a small condensate storage tank are combined and welded, a circumferential welding method is usually adopted. The operator first combines the two cylinders together coaxially, then fixes the two cylinders by spot welding, and then puts the two connected cylinders into the interior of the circumferential welding equipment, thereby welding the two cylinders into a small condensate storage tank through the circumferential welding equipment.

[0004] However, when welding two cylinders in the above welding method, it is necessary to first perform spot welding to fix them, and then transfer the fixed cylinders to the circumferential seam welding equipment for welding. The welding operation is not continuous, which reduces the welding efficiency. In addition, after the two cylinders are coaxially aligned, the two are moved as a whole to the welding equipment for welding. It is easy for the positions of the two cylinders to deviate during the movement, which reduces the coaxiality of the two cylinders and causes connection problems at the spot welding points, thereby affecting the quality of the small condensate storage tank.

[0029] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0030] See also Figure 1 and Figure 2 A condensate storage tank processing and welding device comprises a rectangular frame 1, a feeding mechanism 2 for clamping and transporting the lower half of the condensate storage tank is arranged at the lower part of the rectangular frame 1, and a welding mechanism 3 for positioning and feeding and welding the upper half of the condensate storage tank is arranged on the rectangular frame 1.

[0031] When it is necessary to weld the upper and lower parts of the condensate storage tank, the operator first places the lower half of the condensate storage tank in the feeding mechanism 2, and at the same time, the operator places the upper half of the condensate storage tank in the welding mechanism 3. Then, the feeding mechanism 2 drives the lower half of the condensate storage tank to move to the right, so that the lower half of the condensate storage tank moves to the lower side of the upper half of the condensate storage tank and is coaxial. Then, the welding mechanism 3 combines the upper and lower parts of the condensate storage tank together, and then the upper and lower parts of the condensate storage tank are welded into a condensate storage tank through the welding mechanism 3.

[0032] See also Figure 1 , Figure 2 and Figure 5 The welding mechanism 3 includes a sliding block 31 which is slidably arranged on the upper part of the rectangular frame 1, a return spring is commonly arranged between the right side of the sliding block 31 and the rectangular frame 1, a material storage tube 33 is slidably arranged up and down in the middle part of the sliding block 31, a swivel member 34 is rotatably arranged at the lower part of the material storage tube 33, a material discharge assembly 36 is arranged on the material storage tube 33, and the material discharge assembly 36 includes two sliding square rods 361 which are slidably arranged at the lower rear part of the material storage tube 33 along the front-rear direction, the two sliding square rods 361 are arranged up and down, and a No. 1 hydraulic rod 362 is commonly and fixedly connected between the sliding square rod 361 and the material storage tube 33.

[0033] When it is necessary to weld the upper and lower parts of the condensate storage tank, the operator places the upper half of the condensate storage tank into the storage tube 33 manually or by a robot, and makes the opening of the upper half of the condensate storage tank overlapped with the storage tube 33 downward. At this time, the telescopic section of the No. 1 hydraulic rod 362 on the lower side is in a retracted state, and the telescopic section of the No. 1 hydraulic rod 362 on the upper side is in an extended state, so that the No. 1 hydraulic rod 362 on the upper side drives the upper sliding square rod 361 to be in a state of withdrawing from the interior of the storage tube 33, while the lower sliding square rod 361 is in a state of extending into the interior of the storage tube 33, so that the lower sliding square rod 361 supports the upper half of the lowermost condensate storage tank.

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The feeding mechanism 2 includes an active roller 21 which is symmetrically arranged at the bottom of the rectangular frame 1 for rotation. A conveyor belt 22 which is symmetrically arranged front and back is wound around the two active rollers 21. A movable ring frame 23 which is evenly spaced along its track is fixedly installed between the conveyor belts 22. A rotating disk 24 is rotatably arranged inside the movable ring frame 23. An adjusting component 26 for adjusting the clamping height of the lower half of the condensate storage tank is arranged in the middle of the rotating disk 24.

[0035] See also Figure 3 and Figure 4 The adjustment assembly 26 includes a supporting plate 261 which is slidably arranged in the middle of the rotating disk 24 along the axial direction thereof, a magnet (not shown in the figure) is fixedly mounted on the upper part of the supporting plate 261, and a threaded rod 262 is rotatably arranged on the lower part of the supporting plate 261, and the threaded rod 262 is threadedly connected to the lower part of the rotating disk 24.

[0036] See also Figure 1 , Figure 2 and Figure 5 The welding mechanism 3 also includes a welding assembly 32 arranged on the front side of the lower part of the sliding block 31. The welding assembly 32 includes an L-shaped support plate 321 fixedly installed on the front side of the lower part of the sliding block 31. A No. 2 electric push rod 322 is fixedly installed on the rear side of the lower part of the L-shaped support plate 321. A welding gun 323 is fixedly installed on the rear side of the telescopic section of the No. 2 electric push rod 322.

[0037] The operator rotates the threaded rod 262 in advance according to the height of the lower half of the condensate storage tank, so that the threaded rod 262 drives the supporting plate 261 to adjust the position up and down, so that when the lower half of the condensate storage tank is placed on the supporting plate 261, the upper end surface of the lower half of the condensate storage tank and the welding gun 323 are in the same horizontal plane, and then the telescopic section of the No. 2 electric push rod 322 is adjusted according to the outer diameter of the condensate storage tank, so that the telescopic section of the No. 2 electric push rod 322 drives the welding gun 323 to move and maintain the required welding distance with the condensate storage tank.

[0038] See also Figure 1 , Figure 2 and Figure 3The feeding mechanism 2 also includes a clamping assembly 25 arranged on the rotating disk 24, and the clamping assembly 25 includes a No. 1 clamping plate 251 arranged on the upper part of the rotating disk 24 at equal intervals along the circumference of the rotating disk 24, and the No. 1 clamping plate 251 is slidably connected to the rotating disk 24 along the radial direction. A rotating ear seat 252 is rotatably arranged at the lower part of the rotating disk 24, and a connecting plate 253 is hinged on the outer side of the rotating ear seat 252 at equal intervals along its circumference. The end of the connecting plate 253 away from the rotating ear seat 252 is hinged to the corresponding No. 1 clamping plate 251, and a No. 1 electric push rod 254 is hinged between the rotating ear seat 252 and the rotating disk 24.

[0039] When the upper half of the condensate storage tank is stacked inside the storage pipe 33, the rotating active roller 21 drives the two conveyor belts 22 to start rotating, so that the upper part of the conveyor belt 22 moves to the right, and the conveyor belt 22 drives the movable ring frame 23 thereon to move synchronously, and the movable ring frame 23 drives the rotating disk 24 at the corresponding position to move synchronously. When the conveyor belt 22 drives the movable ring frame 23 to rotate to the upper left part thereof, the operator places the lower half of the condensate storage tank on the upper side of the support plate 261 manually or by a robot.

[0040] It should be noted that an execution motor for driving the active roller 21 to rotate is installed on the rectangular frame 1. The active roller 21 is driven to rotate by starting the execution motor, thereby causing the conveyor belt 22 to rotate. The execution motor is not shown in the figure.

[0041] The supporting plate 261 absorbs the lower half of the condensate storage tank through the magnet on its upper part, so that the lower part of the lower half of the condensate storage tank is close to the supporting plate 261, and then the telescopic section of the No. 1 electric push rod 254 is extended, so that the No. 1 electric push rod 254 drives the rotating ear seat 252 to rotate relative to the rotating disk 24, and the rotating ear seat 252 drives the No. 1 clamping plate 251 to move synchronously to the axial position of the rotating disk 24 through the connecting plate 253, so that the No. 1 clamping plate 251 clamps the lower half of the condensate storage tank and fixes it in the middle position of the rotating disk 24.

[0042] See also Figure 1 , Figure 2 and Figure 6 The welding mechanism 3 also includes a connecting assembly 37 jointly arranged on the swivel member 34 and the rotating disk member 24. The connecting assembly 37 includes connecting columns 371 arranged at equal intervals on the outer side of the swivel member 34 along the circumference thereof. The connecting columns 371 are slidably connected to the swivel member 34 along the vertical direction. A connecting cylinder 372 corresponding to the connecting columns 371 and for inserting the connecting columns 371 is provided on the upper side of the rotating disk member 24. A guide rail member 373 is fixedly installed on the lower outer side of the storage tube 33. The guide rail member 373 is an annular structure with a horizontal rear end and an upwardly inclined front end. The front and rear ends of the guide rail member 373 transition smoothly, and the upper end of the connecting column 371 slides inside the guide rail member 373.

[0043] See also Figure 1 , Figure 2 and Figure 7 A push plate 374 is provided on the rear side of the sliding block 31 for sliding in the vertical direction. The lower end of the push plate 374 corresponds to the rear conveyor belt 22. An inclined surface is provided at the lower end of the push plate 374. A coil spring is provided between the push plate 374 and the sliding block 31. A rectangular groove for the push plate 374 to pass through is provided on the upper right side of the rectangular frame 1. A blocking plate 375 is fixedly installed on the rectangular frame 1 and located at the lower right side of the rectangular groove. A No. 2 hydraulic rod 311 is fixedly installed on the upper side of the sliding block 31. The telescopic section of the No. 2 hydraulic rod 311 is fixedly connected to the storage pipe 33.

[0044] In the initial state, the return spring pushes the sliding block 31 to the left through its own elastic force, and the sliding block 31 drives the storage tube 33 to be located on the left side of the rectangular frame 1. At this time, the telescopic section of the No. 2 hydraulic rod 311 is in an extended state, so that the No. 2 hydraulic rod 311 drives all the connecting columns 371 through the storage tube 33 and the guide rail 373 to be located above the connecting tube 372. The coil spring pushes the push plate 374 downward with its own elastic force, so that the lower end of the push plate 374 rests on the conveyor belt 22, and at the same time, the upper end surface of the push plate 374 is in contact with the lower end surface of the top of the rectangular frame 1.

[0045] When the conveyor belt 22 drives the movable ring frame 23 to move to the right side until it rests on the inclined surface of the pushing plate 374, the movable ring frame 23 drives the rotating disk member 24 to move to a position coaxial with the lower side of the storage tube 33, and then the movable ring frame 23 drives the sliding block 31 to move to the right side synchronously by pushing the pushing plate 374, and the sliding block 31 drives the storage tube 33 to move right synchronously. At the same time, the telescopic section of the retracted No. 2 hydraulic rod 311 drives the storage tube 33 to move downward, and the storage tube 33 drives the connecting column 371 to move downward synchronously through the guide rail member 373, so that the connecting column 371 located at the lower rear part of the guide rail member 373 is inserted into the connecting cylinder 372 at the corresponding position, so that the rotating ring member 34 and the rotating disk member 24 are connected together and rotate synchronously.

[0046] Then, the telescopic section of the No. 1 hydraulic rod 362 on the upper side is retracted, so that the No. 1 hydraulic rod 362 on the upper side drives the upper sliding square rod 361 to fix the upper half of the second condensate storage tank from bottom to top against the inside of the storage tube 33, and then the telescopic section of the No. 1 hydraulic rod 362 on the lower side is extended, so that the lower sliding square rod 361 no longer supports the upper half of the lowermost condensate storage tank, so that the upper half of the lowermost condensate storage tank falls under the action of gravity, and the upper half of the lowermost condensate storage tank passes through the swivel member 34 and falls to the lower half of the condensate storage tank on the upper part of the rotating disk member 24.

[0047] See also Figure 1 , Figure 2 , Figure 5and Figure 6 The welding mechanism 3 also includes a limit assembly 35 arranged on the swivel member 34, and the limit assembly 35 includes a No. 2 clamping plate 351 arranged at a lower part of the swivel member 34 at equal intervals along the circumference of the swivel member 34, and the No. 2 clamping plate 351 is slidably connected with the swivel member 34 along the radial direction. An active swivel 352 is rotatably arranged on the upper part of the swivel member 34, and the active swivel 352 is provided with inclined grooves corresponding to the No. 2 clamping plate 351 at equal intervals along its circumference. The No. 2 clamping plate 351 slides inside the inclined groove through the raised column thereon, and a No. 3 electric push rod 353 is hinged between the swivel member 34 and the active swivel 352.

[0048] When the upper half of the condensate storage tank contacts the lower half of the condensate storage tank, the telescopic section of the No. 3 electric push rod 353 is extended, so that the No. 3 electric push rod 353 drives the active swivel 352 to rotate relative to the swivel member 34, and the swivel member 34 pushes the No. 2 clamp 351 to a position close to the axis of the swivel member 34 through the inclined groove thereon, so that the No. 2 clamp 351 clamps and fixes the upper half of the condensate storage tank at the coaxial position of the swivel member 34, thereby making the upper half of the condensate storage tank and the lower half of the condensate storage tank fit together coaxially.

[0049] See also Figure 1 , Figure 2 and Figure 4 The feeding mechanism 2 also includes a rotating assembly 27 jointly arranged on the rotating disk 24 and the rectangular frame 1. The rotating assembly 27 includes a driven gear 271 fixedly installed on the lower outer part of the rotating disk 24. The driven gear 271 is located on the side of the mobile ring frame 23 close to the conveyor belt 22. A fixed rack 272 is fixedly installed on the rear side of the lower part of the rectangular frame 1. The number of teeth of the fixed rack 272 matches the driven gear 271.

[0050] When the movable ring frame 23 drives the driven gear 271 through the rotating disk 24 to move to mesh with the fixed rack 272 and continue to move, the fixed rack 272 drives the rotating disk 24 to rotate through the driven gear 271, and the rotating disk 24 drives the lower half of the condensate storage tank to rotate through the No. 1 clamp 251. At the same time, the rotating disk 24 drives the rotating ring 34 to rotate synchronously through the connecting tube 372 and the connecting column 371, and the rotating ring 34 drives the upper half of the condensate storage tank to rotate synchronously through the No. 2 clamp 351, thereby making the upper half of the condensate storage tank and the lower half of the condensate storage tank rotate synchronously.

[0051] See also Figure 2 and Figure 5The welding assembly 32 also includes an air duct 324 fixedly installed on the right side of the L-shaped support plate 321. The lower side pipe opening of the air duct 324 faces the left side and corresponds to the position of the welding gun 323. The middle part of the air duct 324 is a telescopic structure. The lower rear part of the air duct 324 is fixedly connected to the telescopic section of the second electric push rod 322, and an air blowing fan 325 is fixedly installed inside the upper side of the air duct 324.

[0052] When the upper half and the lower half of the condensate storage tank begin to rotate, the welding gun 323 is started to weld the annular gap formed by the upper half and the lower half of the condensate storage tank, and the air blowing fan 325 is started at the same time, so that the air blowing fan 325 introduces air into the interior of the air guide pipe 324, and the air guide pipe 324 sprays air from right to left to the position of the welding gun 323, so that the air can quickly take away the heat of the welded part of the condensate storage tank, so as to avoid the high temperature generated by the welding from affecting the stability of the connection between the two parts of the condensate storage tank, and at the same time, the air is used to blow the welding slag away from the condensate storage tank, so as to avoid the high-temperature welding slag from adhering to the condensate storage tank and affecting the quality of the condensate storage tank.

[0053] When the connecting column 371 moving along the guide member 373 moves to the front end of the guide member 373, because the guide member 373 is an annular structure with a horizontal rear end and an upwardly inclined front end, the connecting column 371 rotated to the front side gradually moves upward to the top of the corresponding connecting tube 372, thereby preventing the welding gun 323 from blocking the rotation of the connecting column 371. When the movable ring frame 23 drives the driven gear 271 to move out of engagement with the fixed rack 272, the driven gear 271 drives the condensate storage tank to rotate one circle, so that the welding gun 323 completes the welding of the annular gap formed by the upper half and the lower half of the condensate storage tank, and the welding gun 323 stops working.

[0054] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The feeding mechanism 2 also includes a locking assembly 28 arranged on the movable ring frame 23, and the locking assembly 28 includes positioning holes opened on the outer side of the rotating disk 24 at equal intervals along the circumference thereof, and a positioning plug 281 is slidingly arranged on the rear side of the movable ring frame 23 along the front-to-back direction, and a ramp block 282 is fixedly installed in the middle of the positioning plug 281, and a push spring is arranged between the ramp block 282 and the inner wall of the movable ring frame 23, and an active push block 283 is slidingly arranged on the rear side of the movable ring frame 23 along the axial direction of the movable ring frame 23, and the active push block 283 is slidably connected with the ramp block 282 along the ramp direction thereof, and through holes are opened on the rotating ring member 34 at equal intervals along its circumference, and a locking rod 312 for inserting into the corresponding through hole is fixedly installed on the lower side of the sliding block 31.

[0055] When the driven gear 271 moves to disengage from the fixed rack 272, the movable ring frame 23 drives the active push block 283 to move to the right side of the fixed rack 272, so that the fixed rack 272 no longer blocks the bottom of the active push block 283, and then the push spring pushes the positioning pin 281 through its own elastic force to insert it into the positioning hole at the corresponding position on the rotating disk 24, thereby fixing the rotation angle of the rotating disk 24, and the positioning pin 281 pushes the active push block 283 downward through the inclined block 282.

[0056] It should be noted that a slope is provided at the left end of the fixed rack 272 to facilitate the active push block 283 to move to the upper part along the slope of the left end of the fixed rack 272, so that the active push block 283 drives the positioning column 281 to exit the positioning hole through the slope block 282.

[0057] Then, the telescopic sections of the No. 1 electric push rod 254 and the No. 3 electric push rod 353 are retracted, so that the No. 1 clamp 251 and the No. 2 clamp 351 no longer clamp the condensate storage tank, and then the telescopic section of the No. 2 hydraulic rod 311 is extended to drive the storage pipe 33 to move upward to the initial position, so that the connecting column 371 is disengaged from the connecting tube 372, and at the same time, the storage pipe 33 drives the swivel member 34 to move upward synchronously, so that the locking rod 312 is inserted into the through hole position of the corresponding position of the swivel member 34, and the rotation angle of the swivel member 34 is locked by the locking rod 312, so that the positions of the connecting column 371 and the connecting tube 372 after disconnection can still correspond, thereby facilitating the reconnection of the connecting column 371 and the connecting tube 372.

[0058] Afterwards, the mobile ring frame 23 pushes the push plate 374 to move until the push plate 374 abuts against the left side of the blocking plate 375, so that the push plate 374 can no longer move to the right. At this time, the upper part of the push plate 374 moves to the bottom of the rectangular groove of the rectangular frame 1. Then, the mobile ring frame 23 pushes the push plate 374 upward through the inclined surface of the push plate 374, so that the push plate 374 does not hinder the movement of the mobile ring frame 23. Then, the return spring pushes the sliding block 31 to return to the initial position to the left, and the mobile ring frame 23 moves to the lower right side of the conveyor belt 22, thereby unloading the condensate storage tank. It should be noted that the elastic force of the return spring is large enough to overcome the gravity of the storage tube 33, the sliding block 31 and other structures carrying the upper half of the condensate storage tank. In order to reduce the friction resistance of the sliding block 31, a rolling structure such as a roller can be set on the sliding block 31, and the sliding block 31 is slidably connected to the rectangular frame 1 through the rolling structure.

[0059] See also Figure 1-Figure 7When welding a small condensate storage tank, the present invention specifically includes the following steps: In the first step, the operator rotates the threaded rod 262 according to the height of the lower half of the condensate storage tank in advance, so that the supporting plate 261 can drive the upper end surface of the lower half of the condensate storage tank and the welding gun 323 to be in the same horizontal plane, and then adjusts the telescopic section of the No. 2 electric push rod 322 according to the outer diameter of the condensate storage tank, so that the welding gun 323 can maintain the required welding distance with the condensate storage tank.

[0060] In the second step, the operator manually or mechanically adds the upper half of the condensate storage tank to the interior of the storage pipe 33, so that the sliding square rod 361 on the lower side supports the upper half of the lowermost condensate storage tank, and the rotating conveyor belt 22 drives the movable ring frame 23 to move. The operator manually or mechanically places the lower half of the condensate storage tank on the upper side of the supporting plate 261.

[0061] The third step is to extend the telescopic section of the No. 1 electric push rod 254 so that the No. 1 clamping plate 251 clamps the lower half of the condensate storage tank on the axial position of the rotating disk 24, and the movable ring frame 23 moves to the right side until it rests on the inclined surface of the push plate 374, and the telescopic section of the No. 2 hydraulic rod 311 is retracted so that the swivel member 34 is connected with the rotating disk 24 and rotates synchronously.

[0062] In the fourth step, the upper half of the lowermost condensate storage tank falls under the action of gravity through the telescopic section of the No. 1 hydraulic rod 362, and then the upper half of the lowermost condensate storage tank passes through the swivel member 34 and falls to the lower half of the condensate storage tank on the upper part of the rotating disk member 24.

[0063] The fifth step is to extend the telescopic section of the third electric push rod 353 so that the second clamping plate 351 clamps the upper half of the condensate storage tank at the coaxial position of the rotating ring 34, thereby making the upper half of the condensate storage tank and the lower half of the condensate storage tank coaxially fit together.

[0064] In the sixth step, the mobile ring frame 23 drives the driven gear 271 to move to mesh with the fixed rack 272, so that the upper half of the condensate storage tank and the lower half of the condensate storage tank rotate synchronously, and the welding gun 323 is started to weld the annular gap of the condensate storage tank, and the air blowing fan 325 is used to cool the condensate storage tank and blow away the welding slag.

[0065] In the seventh step, when the mobile ring frame 23 drives the driven gear 271 to move to disengage from the fixed rack 272, the driven gear 271 drives the condensate storage tank to rotate one circle, so that the welding gun 323 completes the welding of the annular gap formed by the upper half and the lower half of the condensate storage tank, and the welding gun 323 is stopped.

[0066] The eighth step is to retract the telescopic sections of the No. 1 electric push rod 254 and the No. 3 electric push rod 353 so that the No. 1 clamp 251 and the No. 2 clamp 351 no longer clamp the condensate storage tank, extend the telescopic section of the No. 2 hydraulic rod 311 to drive the storage tube 33 to move upward to the initial position, so that the connecting column 371 and the connecting tube 372 are out of contact, and the mobile ring frame 23 moves to the lower right side of the conveyor belt 22, thereby unloading the condensate storage tank.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
