DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] In one embodiment, see Figure 1 , Figure 2 and Figure 3 A welding and positioning device for loader components comprises a welding platform 1, a plurality of legs 8 are fixed at the bottom of the welding platform 1, a support plate 4 is arranged above the welding platform 1, a symmetrically distributed clamping plate 5 is arranged on the side of the support plate 4, a plurality of sliders 9 are integrally formed at the bottom of the clamping plate 5, a plurality of slideways 10 adapted to the sliders 9 are arranged inside the welding platform 1, the sliders 9 penetrate the slideways 10 and are slidably connected with the slideways 10, the clamping plate 5 is connected to the support plate 4 through a transmission mechanism 2, when the support plate 4 is subjected to pressure, the support plate 4 drives the clamping plates 5 to approach each other through the transmission mechanism 2, the legs 8 are fixedly connected with a fixing plate 7, a guide plate 11 is fixed at the bottom of the fixing plate 7, a push rod 6 is penetrated inside the guide plate 11, the push rod 6 is slidably connected with the guide plate 11, the push rod 6 is connected with a clamping mechanism 3, and the clamping mechanism 3 is used to clamp the loader components.

[0025] In this embodiment, when the device is welding the loader parts, the loader parts to be welded are placed on the surface of the support plate 4 on the top of the welding platform 1. The support plate 4 moves downward under the pressure of the loader parts. While the support plate 4 moves downward, it is driven by the transmission mechanism 2 and the clamping plates 5 on both sides are synchronously close to each other. The clamping plates 5 are close to each other and push the loader parts, so that the loader parts are located at the center position of the support plate 4, which is convenient for the welding device to weld the loader parts. The loader parts are positioned by the clamping plates 5 by using their own gravity. There is no need to manually position the loader parts, which saves manpower. After the loader parts are positioned, the staff pushes the push rod 6. While the push rod 6 moves, it clamps the loader parts through the clamping mechanism 3, thereby fixing the loader parts and effectively improving the stability of the loader parts during welding.

[0026] See also Figure 3The transmission mechanism 2 includes a guide cylinder 22 that passes through the fixed plate 7, and two relatively distributed traction ropes 25 are fixed to the outside of the guide cylinder 22. The other ends of the traction ropes 25 are respectively fixedly connected to the sliders 9 at the bottom of the two clamps 5. A guide column 24 is fixed to the bottom of the welding platform 1. A guide groove is penetrated inside the guide column 24, and the traction rope 25 passes through the inside of the guide groove. A slide bar 21 is fixed to the bottom of the support plate 4. The slide bar 21 passes through the welding platform 1 and the top of the guide cylinder 22 and is slidably connected to the two. A rotating component is provided between the slide bar 21 and the guide cylinder 22. When the slide bar 21 moves up and down, the rotating component is used to drive the guide cylinder 22 to rotate. A reset component is provided between the slideway 10 and the slider 9, and the reset component is used to reset the clamp 5; After the support plate 4 is subjected to the pressure of the loader component, it drives the sliding rod 21 to move downward. While the sliding rod 21 moves downward, it drives the guide cylinder 22 to rotate through the rotating assembly. While the guide cylinder 22 rotates, it reels the traction rope 25. Under the guidance of the guide groove, the traction rope 25 is retracted and the clamping plate 5 is pulled, so that the clamping plates 5 are close to each other until the clamping plates 5 complete the positioning of the loader component. The loader component's own gravity is used to enable the clamping plates 5 to complete the positioning of the loader component. There is no need to manually position the loader component, saving manpower. When the loader component is welded, the staff removes the loader component from the support plate 4. After the support plate 4 loses the pressure of the loader component, the resetting assembly drives the clamping plate 5 to automatically reset. The clamping plate 5 drives the guide cylinder 22 to rotate in the opposite direction through the traction rope 25, and the guide cylinder 22 drives the sliding plate 21 upward through the rotating assembly, thereby resetting the support plate 4 synchronously.

[0027] See also Figure 3 The reset assembly includes a limit rod 27 fixedly connected to the inner wall of one of the slideways 10, the limit rod 27 passes through one of the sliders 9 and is slidably connected to the slider 9, and a first elastic member 26 is provided outside the limit rod 27, and the two ends of the first elastic member 26 are respectively fixedly connected to the inner wall of the slideway 10 and the side wall of the slider 9; When the welding of the loader parts is completed, the staff removes the loader parts from the support plate 4. After the support plate 4 loses the pressure of the loader parts, the clamps 5 move away from each other under the action of the first elastic member 26. At the same time, the clamps 5 drive the guide cylinder 22 to reverse through the traction rope 25, and the guide cylinder 22 drives the slide rod 21 to move upward through the rotating assembly, so that the support plate 4 is automatically reset, wherein the first elastic member 26 can be a spring. In addition, the limit rod 27 can play a limiting role on the slider 9, thereby improving the stability of the clamp 5 when moving.

[0028] See also Figure 4The rotating assembly includes a protrusion 28 fixedly connected to the outer wall of the slide rod 21, wherein a spiral groove 29 adapted to the protrusion 28 is provided on the inner wall of the guide cylinder 22, the protrusion 28 is located inside the spiral groove 29 and is slidably connected to the spiral groove 29, and a fixing component is provided at the bottom of the guide cylinder 22, which is used to fix the guide cylinder 22, thereby limiting the rotation of the guide cylinder 22.

[0029] When the slide bar 21 moves downward, it drives the protrusion 28 to move downward. When the protrusion 28 moves downward, it squeezes the guide cylinder 22 through the spiral groove 29, thereby causing the guide cylinder 22 to rotate. As a result, the slide bar 21 can move downward while the traction rope 25 can be reeled in through the guide cylinder 22. When the clamping plate 5 has completed the welding and positioning of the loader components, the guide cylinder 22 is fixed by a fixing component to limit the rotation of the guide cylinder 22, thereby ensuring the traction force of the guide cylinder 22 on the slider 9 through the traction rope 25, preventing the clamping plate 5 from resetting, and effectively improving the positioning effect of the clamping plate 5 on the loader components.

[0030] See also Figure 5 The fixing component includes a through hole 210 arranged at the bottom of the guide cylinder 22, a conical block 211 is arranged below the through hole 210, a baffle 212 is fixedly connected to the bottom of the conical block 211, a symmetrically distributed support rod 213 is fixed to the top of the baffle 212, the support rod 213 passes through the fixed plate 7 and is slidably connected to the fixed plate 7, a second elastic member 214 is arranged outside the support rod 213, and two ends of the second elastic member 214 are respectively fixedly connected to the top of the baffle 212 and the bottom of the fixed plate 7, and a trapezoidal block 23 for squeezing the baffle 212 is fixed to the top of the push rod 6; After the clamping plate 5 has positioned the loader components, it pushes the push rod 6, which drives the trapezoidal block 23 to move. The inclined surface of the trapezoidal block 23 will squeeze the baffle 212, so that the baffle 212 drives the conical block 211 to move upward. When the plane at the top of the trapezoidal block 23 fits with the bottom of the baffle 212, the conical block 211 fits tightly with the bottom of the inner wall of the through hole 210. Under the action of friction, the conical block 211 limits the rotation of the guide cylinder 22, which effectively improves the stability of the guide cylinder 22. The fixed plate 7 can limit the baffle 212 through the support rod 213, thereby improving the stability of the baffle 212 when moving. The second elastic member 214 can be a spring, which can reset the baffle 212.

[0031] See also Figure 5The clamping mechanism 3 includes an air pressure groove 32 arranged inside the clamping plate 5, and the air pressure groove 32 is connected to an inflatable component, and the inflatable component is used to inflate the air pressure groove 32. A plurality of air pressure holes 34 are arranged on the inner wall of the air pressure groove 32, and the inside of the air pressure holes 34 are all slidably connected with a push rod 31, and one end of the air pressure hole 34 close to the air pressure groove 32 is connected to the inner wall of the air pressure groove 32 through a third elastic member 33; After the clamp 5 has positioned the loader component, the staff pushes the push rod 6. While the push rod 6 moves, air is inflated into the air pressure groove 32 through the inflation assembly. The increased air pressure inside the air pressure groove 32 pushes the push rods 31 inside the multiple air pressure holes 34, so that the push rods 31 move toward the loader component until all the ends of the push rods 31 are in contact with the loader component. The loader component is clamped by multiple push rods 31, which can effectively improve the stability of the loader component during welding, and can also clamp and fix different components of the loader, thereby improving the application range of the device. The third elastic member 33 can be a spring, which can play a resetting role on the push rod 31.

[0032] See also Figure 2 , Figure 5 and Figure 6 The inflation assembly includes a limit plate 37 fixedly connected to the bottom of the fixed plate 7, a pressure cylinder 36 fixedly connected to the limit plate 37, a piston 39 slidably connected inside the pressure cylinder 36, and the piston 39 is fixedly connected to the push rod 6, wherein the pressure cylinder 36 is connected to an air pipe 38, and the other end of the air pipe 38 is connected to the air pressure groove 32, and a self-locking component is provided inside the guide plate 11, and the self-locking component is used to fix the push rod 6; After the clamping plate 5 has positioned the loader component, the staff pushes the push rod 6, and the push rod 6 drives the piston 39 to move inside the air cylinder 36. The piston 39 squeezes the gas inside the air cylinder 36 while moving, so that the gas inside the air cylinder 36 enters the air pressure groove 32 inside the two clamping plates 5 through the air pipe 38, so that the push rod 31 can complete the clamping of the loader component. When the push rod 31 completes the clamping of the loader component, the self-locking component inside the guide plate 11 will automatically fix the push rod 6, effectively ensuring the stability of the push rod 6, and then ensuring the clamping effect of the push rod 31 on the loader component.

[0033] See also Figure 4The self-locking component includes a wedge block 312 that penetrates the side wall of the guide plate 11, and the wedge block 312 is slidably connected to the inner wall of the guide plate 11. A stopper 310 is fixed to one end of the wedge block 312 located outside the guide plate 11, and the stopper 310 is connected to the outer wall of the guide plate 11 through a fourth elastic member 311, wherein a plurality of limiting grooves 313 adapted to the wedge block 312 are provided on the side wall of the push rod 6, and a push plate 35 is fixed to one end of the push rod 6 away from the piston 39, and the push plate 35 is connected to the side wall of the guide plate 11 through a fifth elastic member 314; When the clamping plate 5 has finished positioning the loader component, the staff pushes the push rod 6. While the push rod 6 moves, the limit groove 313 will squeeze the inclined surface of the wedge block 312, and the wedge block 312 will not interfere with the movement of the push rod 6. When the support rod 31 has finished clamping the loader component, the push rod 6 stops being pushed, and the end of the wedge block 312 automatically enters one of the limit grooves 313 under the action of the stop block 310 and the fourth elastic member 311. At this time, the plane of the wedge block 312 limits the push rod 6 through the limit groove 313, thereby limiting the reset of the push rod 6, effectively improving the stability of the push rod 6. When the loader component is welded, the wedge block 312 is pulled out of the limit groove 313 through the stop block 310, and the push rod 6 automatically resets under the action of the push plate 35 and the fourth elastic member 311, wherein the fourth elastic member 311 and the fifth elastic member 314 can both be springs.

[0034] Working principle: When the device is welding the loader parts, the loader parts to be welded are placed on the surface of the support plate 4 on the top of the welding platform 1. The support plate 4 moves downward under the pressure of the loader parts. While the support plate 4 moves downward, the protrusion 28 is driven downward by the slide bar 21. While the protrusion 28 moves downward, it squeezes the guide cylinder 22 through the spiral groove 29, thereby causing the guide cylinder 22 to rotate. While the guide cylinder 22 rotates, the traction rope 25 is wound up. While the traction rope 25 is wound up, the clamping plate 5 is pulled, so that the clamping plates 5 are close to each other until the clamping plates 5 complete the welding of the loader parts. The clamping plate 5 can be used to position the loader components by utilizing the gravity of the loader components. There is no need to manually position the loader components, which saves manpower. After the clamping plate 5 has positioned the loader components, the staff pushes the push rod 6, which drives the trapezoidal block 23 to move. The inclined surface of the trapezoidal block 23 squeezes the baffle 212, so that the baffle 212 drives the conical block 211 to move upward. When the plane at the top of the trapezoidal block 23 fits with the bottom of the baffle 212, the conical block 211 fits tightly with the bottom of the inner wall of the through hole 210. Under the action of friction, the conical block 211 limits the guide The push rod 6 also drives the piston 39 to move inside the air cylinder 36. The piston 39 squeezes the gas inside the air cylinder 36 while moving, so that the gas inside the air cylinder 36 enters the air pressure groove 32 inside the two clamping plates 5 through the air pipe 38. The air pressure inside the air pressure groove 32 increases, pushing the push rods 31 inside the multiple air pressure holes 34, so that the push rods 31 move toward the direction of the loader parts until all the ends of the push rods 31 are in contact with the loader parts. The loader parts are clamped by multiple push rods 31, which can effectively The stability of the loader parts during welding is improved, and different parts of the loader can be clamped and fixed, thereby improving the scope of application of the device. When the push rod 31 has finished clamping the loader parts, the push rod 6 is stopped, and the wedge block 312 automatically enters one of the limit grooves 313. At this time, the plane of the wedge block 312 limits the push rod 6 through the limit groove 313, thereby limiting the reset of the push rod 6, effectively improving the stability of the push rod 6, and further ensuring the clamping effect of the push rod 31 on the loader parts, effectively improving the stability of the loader parts during welding.
