Description

Technical Field

[0001] The invention relates to the technical field of welding of a sprinkler underframe, in particular to an automatic welding tool for a reel sprinkler underframe. Background Art

[0002] Reel sprinkler is a common type of sprinkler. It is an irrigation machine that winds the traction PE pipe on the winch, uses the sprinkler pressure water to drive the gearbox to drive the winch to rotate, and pulls the sprinkler car to automatically move and spray. The reel sprinkler can irrigate a large area of ​​farmland, and can also control the amount of water sprayed according to the sprinkler to meet the different requirements of users for the amount of sprinkler water. It is a sprinkler equipment commonly used for water-saving irrigation of farmland;

[0003] When welding the chassis, it is necessary to place multiple square pipes horizontally on the welding platform, and then design a relatively movable clamping mechanism on the outside of the pipe to achieve the purpose of fixing and positioning the chassis before welding. Since multiple pipes are placed horizontally before forming the chassis, it is easy for the bottom outer walls of the pipes to contact the workbench during subsequent welding, which may make it difficult for the pipe in the middle of the chassis to be in the middle position during subsequent welding, resulting in positional deviations at the subsequent welding, affecting the accuracy of subsequent welding positioning and the dimensional accuracy after subsequent splicing.

[0037] Among them, the airbag is communicated with the inside of the cylindrical groove through the hollow spring rod. A limiting plate II is rotatably connected to the side of the semi-circular plate II close to the translation plate. One side of the limiting plate II away from the semi-circular plate II is fixedly connected to the side wall of the translation plate.

[0038] The present invention has the following beneficial effects:

[0039] 1. In the present invention, when the support plate rises, it will generate an upward driving force on the cross beam between the chassis through the rectangular plate, enabling the cross beam in the middle of the frame to be located in the middle of the chassis. At the same time, the rectangular plate will be driven by the reaction force of the cross beam to drive the connecting plate to slide downward. When the connecting plate slides downward, the inclined part of its side wall will be squeezed by the inclined part of the inclined block, thereby driving the L plate to generate an inward pulling force on the outside of the chassis, enabling the middle cross beam to be located in the middle of the steel pipe. At the same time, the pulling of the L plate on the steel pipe of the chassis can make the steel pipe and the cross beam in close contact. Through the cooperation of the rectangular plate and the L plate, the cross beam steel pipe in the middle of the chassis can be located at the center of the steel pipe during welding, reducing welding defects caused by the downward movement of the middle of the cross beam, maintaining the stability and position accuracy of the cross beam in the middle of the chassis, and improving the subsequent welding accuracy at the same time.

[0040] 2. In the present invention, when the sliding block slides, its inclined part will first squeeze the through groove at the bottom of the translation plate and slide upward on the two spring shafts. At this time, the fixed plate will be in an approximately horizontal state on the arc plate. Subsequently, when the sliding block continues to slide, it will squeeze the bottom end of the arc plate to rotate in a semi-circle. When the arc plate rotates, it will generate a driving force on the translation plate. When the auxiliary plates on both sides of the cross beam contact its side wall, it can play a role in pushing and straightening the cross beam, and ensure that the cross beam can present a linear motion state when being pushed by the connecting plate, reducing the situation that when the cross beam steel pipe is pushed upward, due to different contact positions and pressures between the two sides of the cross beam steel pipe and the other steel pipes, when the connecting plate pushes the cross beam, the cross beam is subjected to uneven driving forces, resulting in deflection during the subsequent upward movement under the push, improving the accurate positioning of the position during welding, enhancing the dimensional accuracy of the chassis after welding, reducing the increase in the rejection rate caused by deflection, and improving the accuracy of positioning and position.

[0041] 3. In the present invention, when the translation plate pushes the side wall of the cross beam, it will cause the auxiliary plate to squeeze the semi-circular plate II under the reaction force of the cross beam. After being squeezed, the semi-circular plate II will slide upward under the restriction of the short rod and generate a certain upward sliding on the side wall of the cross beam, reducing the situation that when the two sides of the cross beam are squeezed by the auxiliary plate, the friction between the cross beam and the auxiliary plate is too large, resulting in difficulty for the cross beam to slide upward and affecting the subsequent position positioning. At the same time, the hollow spring rod will squeeze the gas inside the cylindrical groove to make the airbag expand. At this time, the expanded airbag will enable the cross beam to stop accurately in position among the other steel pipes when the cross beam is subjected to the thrust, reducing the situation that the cross beam slides excessively under the action of the semi-circular plate II and the thrust, thereby being able to further enhance the positioning and splicing quality of the steel pipe of the chassis and improve the welding accuracy.

[0042] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] A translation assembly 32, which is installed on the side wall of the pushing assembly 31 through a flipping member;

[0068] An inflating assembly 33, which is installed on the side wall of the translation assembly 32 through an inflating member;

[0069] Among them, by pushing the translation assembly 32 by the pushing assembly 31, the translation assembly 32 can move upward while driving the inflating assembly 33 to straighten the two sides of the cross beam of the chassis, ensuring accurate welding in the follow-up.

[0070] The flipping assembly 11 includes two rectangular grooves 112 opened on the side wall of the placement rack 111, and square grooves are opened on both the left and right sides of the rectangular grooves 112;

[0071] Among them, a motor 114 is fixedly connected to the side wall of the right support frame 101, and the output end of the motor 114 penetrates through the side wall of the support frame 101 and is fixedly connected to the placement rack 111;

[0072] The limiting member includes a plurality of limiting shafts 113 fixedly connected to the top of the placement rack 111. First, a plurality of steel pipes to be welded into the chassis and the cross beam in the middle of the chassis are sequentially arranged between the limiting shafts 113 on the placement rack 111 and spliced into the frame of the chassis. Then, the electric push rod 122 is started. When the electric push rod 122 works, it will clamp the two sides of the frame through the L-shaped plate 212, so that the steel pipes are in close contact with each other. Then, the chassis is welded by an external welding device and the motor 114 is started as required to drive the placement rack 111 to flip and weld.

[0073] The transmission assembly 12 includes two bearing racks 121 fixedly connected to the bottom of the placement rack 111. Two electric push rods 122 are fixedly connected to the inner wall of one side of the bearing rack 121 close to the placement rack 111. The output ends of the two electric push rods 122 are fixedly connected to a support plate 123. When the support plate 123 rises, it will generate an upward driving force on the cross beam between the chassis through the rectangular plate 213, enabling the cross beam in the middle of the frame to be in the middle position of the chassis. At the same time, the rectangular plate 213 will be driven by the reaction force of the cross beam to drive the connecting plate 301 to slide downward.

[0074] The elastic member includes two return springs fixedly connected to the bottom of the Y-shaped frame 201, and the bottoms of the two springs are fixedly connected to the support plate 123;

[0075] The sliding assembly 21 includes two spring sleeves 211 slidably connected to the top of the Y-shaped frame 201. A tension spring is fixedly connected between the two spring sleeves 211, and the middle of the tension spring is fixedly connected to the side wall of the Y-shaped frame 201;

[0076] Among them, one side of the spring sleeve 211 far from the middle of the Y-shaped frame 201 is inclined, an L-shaped plate 212 is slidably connected to the inclined part of the spring sleeve 211, and a rectangular plate 213 is fixedly connected to the top of the Y-shaped frame 201;

[0077] The limiting component 22 includes two inclined blocks 221 fixedly connected to the top of the support plate 123. Among them, the bottom of the Y-shaped frame 201 slides through the side wall of the electric push rod 122. When the connecting plate 301 slides downward, the inclined part of its side wall will be squeezed by the inclined part of the inclined block 221, thereby driving the L-shaped plate 212 to generate an inward pulling force on the outside of the bottom frame, so that the middle cross beam can be located in the middle of the steel pipe. At the same time, the pulling of the L-shaped plate 212 on the steel pipe of the bottom frame can enable the steel pipe and the cross beam to be in close contact.

[0078] The pushing component 31 includes a sliding block 311 rotatably connected to the side of the connecting plate 301 away from the support plate 123, and the sliding block 311 is slidably connected to the inside of the square groove;

[0079] The fixing member includes a limiting plate 312 provided on the side wall of the sliding block 311. The limiting plate 312 is fixedly connected to the side wall of the placing rack 111. Two spring shafts 313 are slidably connected to the top of the limiting plate 312, and two connecting plates 301 are rotatably connected to the outer wall of the top of the support plate 123;

[0080] The translation component 32 includes a translation plate 321 fixedly connected to the tops of the two spring shafts 313. Two fixing plates 322 are rotatably connected to the side of the translation plate 321 away from the connecting plate 301;

[0081] Among them, a through groove is provided on the side wall of the fixing plate 322. When the sliding block 311 slides, its inclined part will first squeeze the through groove at the bottom of the translation plate 321 and slide upward on the two spring shafts 313. At this time, the fixing plate 322 will be in an approximately horizontal state on the arc plate 323. Subsequently, when the sliding block 311 continues to slide, it will squeeze the bottom end of the arc plate 323 to perform a semi-circular rotation.

[0082] The flipping member includes an arc plate 323 rotatably connected between the two fixing plates 322. The side wall of the arc plate 323 is hollow, and a long rod 324 is slidably connected to the inside of the arc plate 323;

[0083] Among them, an arc spring is fixedly connected to the outer surface of the long rod 324. One end of the arc spring away from the long rod 324 is fixedly connected to the inside of the arc plate 323. The long rod 324 is fixedly connected to the inside of the placing rack 111. A cylindrical groove is provided on the side wall of the translation plate 321. When the arc plate 323 rotates, it will generate a pushing force on the translation plate 321. When the auxiliary plates 332 on both sides of the cross beam contact its side wall, it can play a role in pushing and straightening the cross beam, and ensure that the cross beam can present a linear motion state when being pushed by the connecting plate 301.

[0084] The inflatable component 33 includes a hollow spring rod 331 fixedly connected to the inner wall of the cylindrical groove. On the primary side of the hollow spring rod 331 away from the translation plate 321, an auxiliary plate 332 is fixedly connected. Two long grooves are formed in the side wall of the auxiliary plate 332, and short rods are fixedly connected to the inner walls of the long grooves.

[0085] The expansion member includes a semi-circular plate two 333 slidably connected to the outer surface of the short rod. A number of balls are rotatably connected to the side of the semi-circular plate two 333 away from the translation plate 321. An airbag 334 is fixedly connected to the side of the auxiliary plate 332 away from the hollow spring rod 331.

[0086] Among them, the airbag 334 is communicatively arranged with the inside of the cylindrical groove through the hollow spring rod 331. A limiting plate two 335 is rotatably connected to the side of the semi-circular plate two 333 close to the translation plate 321. The side of the limiting plate two 335 away from the semi-circular plate two 333 is fixedly connected to the side wall of the translation plate 321. When the side wall of the translation plate 321 pushes the side wall of the cross beam, due to the reaction force of the cross beam, the auxiliary plate 332 will squeeze the semi-circular plate two 333. After being squeezed, the semi-circular plate two 333 will slide upward under the restriction of the short rod and produce a certain upward sliding on the side wall of the cross beam, reducing the situation that when the two sides of the cross beam are squeezed by the auxiliary plate 332, the friction between the cross beam and the auxiliary plate 332 is too large, resulting in the difficulty of the cross beam to slide upward and affecting the subsequent position positioning.

[0087] During use, first, a number of steel pipes to be welded into the chassis and the cross beam in the middle of the chassis are sequentially arranged between the limiting shafts 113 on the placing rack 111 and spliced into the frame of the chassis. Then, the electric push rod 122 is started. When the electric push rod 122 works, it will clamp the two sides of the frame relatively through the L plate 212, so that the steel pipes are in close contact with each other. Then, the chassis is welded by an external welding device and the motor 114 is started as required to drive the placing rack 111 to turn over for welding.

[0088] When the two electric push rods 122 are working, they will drive the support plate 123 to rise. When the support plate 123 rises, it will drive the connecting plate 301 to rise synchronously. When the connecting plate 301 rises, it will generate an upward driving force on the cross beam between the chassis through the rectangular plate 213. When the connecting plate 301 rises and pushes the cross beam upward through the rectangular plate 213, the cross beam in the middle of the frame can be positioned in the middle of the chassis. At the same time, when the rectangular plate 213 pushes the cross beam upward, the rectangular plate 213 will be driven by the reaction force of the cross beam to drive the connecting plate 301 to slide downward. When the connecting plate 301 slides downward, the inclined part of its side wall will be squeezed by the inclined part of the inclined block 221, and then the L plate 212 will drive an inward pulling force on the outside of the chassis, so that when the middle cross beam can be positioned in the middle of the steel pipe, the pulling of the L plate 212 on the chassis steel pipe can make the steel pipe and the cross beam in close contact. Through the cooperation of the rectangular plate 213 and the L plate 212, the cross beam steel pipe in the middle of the chassis can be positioned at the center of the steel pipe during welding, reducing welding defects caused by the downward movement of the middle of the cross beam, maintaining the stability and position accuracy of the cross beam in the middle of the chassis, and improving the subsequent welding accuracy at the same time.

[0089] When the electric push rod 122 pushes the support plate 123 to move upward, the upward movement of the support plate 123 will push the sliding block 311 to slide in the direction of the translation plate 321 through the connecting plate 301. When the sliding block 311 slides, its inclined part will first squeeze the through groove at the bottom of the translation plate 321. When the translation plate 321 is squeezed by the inclined part of the sliding block 311, it will first slide upward on the two spring shafts 313. At this time, the fixed plate 322 will be in an approximately horizontal state on the arc plate 323. Subsequently, when the sliding block 311 continues to slide, it will squeeze the bottom end of the arc plate 323. After the bottom end of the arc plate 323 is squeezed, it will rotate in a semicircle on the long rod 324. When the arc plate 323 rotates in a semicircle, it will generate a driving force on the translation plate 321 through the fixed plate 322. After the translation plate 321 is pushed by the fixed plate 322, it will contact the side wall of the cross beam through the auxiliary plate 332. When the two auxiliary plates 332 on both sides of the cross beam contact its side wall, the contact between the two auxiliary plates 332 and the cross beam can play a role in pushing and straightening the cross beam, and ensure that the cross beam can move in a straight line when pushed by the connecting plate 301, reducing the situation that when the cross beam steel pipe is pushed upward, due to the different contact positions and pressures between the two sides of the cross beam steel pipe and the other steel pipes, when the connecting plate 301 pushes the cross beam, the cross beam is subjected to an uneven driving force, resulting in deflection during the subsequent upward movement, improving the accurate positioning during welding, enhancing the dimensional accuracy of the chassis after welding, reducing the increase in the rejection rate caused by deflection, and improving the accuracy of positioning and position.

[0090] When the translation plate 321 pushes the side wall of the cross beam through the auxiliary plate 332, the auxiliary plate 332 will be under the reaction force of the cross beam. When the translation plate 321 continues to move, the auxiliary plate 332 will squeeze the second semi-circular plate 333. After being squeezed by the auxiliary plate 332, the second semi-circular plate 333 will slide upward inside the long groove under the restriction of the short rod. When the second semi-circular plate 333 slides upward, it will produce a certain upward sliding on the side wall of the cross beam, reducing the situation that the friction between the cross beam and the auxiliary plate 332 is too large when the two sides of the cross beam are squeezed by the auxiliary plate 332, which makes it difficult for the cross beam to slide upward and affects the subsequent position positioning. At the same time, when the auxiliary plate 332 slides in the direction of the translation plate 321 under the reaction force, the hollow spring rod 331 will squeeze the gas inside the cylindrical groove. After being squeezed, the gas will cause the airbag 334 to expand. At this time, the expanded airbag 334 will enable the cross beam to accurately stop in position among the other steel pipes when the cross beam is subjected to the thrust, reducing the situation that the cross beam slides excessively under the action of the second semi-circular plate 333 and the thrust. Thus, it can further enhance the positioning and splicing quality of the chassis steel pipes and improve the welding accuracy.
