Description

Technical Field

[0001] This utility model relates to the technical field of bucket welding, and in particular to a loader bucket welding positioning device. Background Technology

[0002] Buckets are the most commonly used structural components in agricultural machinery, mining machinery, and construction machinery. Bucket components generally include inner stiffening plates, arc-shaped outer sealing plates, connecting lugs, side sealing plates, and cutting edges.

[0003] Existing loader bucket welding positioning devices, such as the bucket welding fixture device disclosed in utility model patent application number 201821052672.7, mainly include a welding base, an inner support welding positioning structure, a connecting lug positioning structure, a blade plate positioning component, a movable pneumatic clamping structure, and a side sealing plate pneumatic clamping structure. The inner support welding positioning structure is located in the middle area of ​​the welding base, and the connecting lug positioning structure is located on one side of the inner support connecting positioning structure. In use, the push-pull cylinder is retracted to its end, and the side sealing plate of the workpiece to be processed is placed on the sliding component. Due to magnetic force, it will be well positioned. Then, the other components are placed, and then the pneumatic system is activated. The cylinder extends, and together with the side sealing plate workpiece, it is well integrated and positioned with the other components of the bucket.

[0004] However, most existing welding positioning devices are fixed and difficult to apply to buckets of different sizes, thus limiting their applicability. Moreover, since buckets are irregular in shape, existing positioning devices cannot provide a good fixing effect, which can easily affect the subsequent welding results. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a loader bucket welding positioning device that not only facilitates the welding of buckets of different sizes, thus improving the applicability of the device, but also enhances the fixing effect on the bucket and prevents the bucket from shaking during the welding process.

[0006] This utility model discloses a loader bucket welding and positioning device, including a support mechanism; it also includes two sets of clamping mechanisms, a moving mechanism, two sets of adsorption mechanisms, and a pressing mechanism. The two sets of clamping mechanisms are mounted on the support mechanism and clamp the bucket. The moving mechanism is mounted on the support mechanism and drives the two sets of adsorption mechanisms to move. The two sets of adsorption mechanisms are mounted on the moving mechanism and fix the side plates. The pressing mechanism is mounted on the support mechanism and fixes and presses the bucket. Workers hoist the bucket body onto the support mechanism, and the two sets of clamping mechanisms clamp the bucket on both sides, facilitating the adaptation to buckets of different sizes. Then, the two sets of side plates are fixed to the two sets of adsorption mechanisms respectively. The moving mechanism moves the two sets of adsorption mechanisms closer together, making the side plates fit tightly against both sides of the bucket. Finally, the pressing mechanism presses and fixes the bucket body, facilitating welding by workers.

[0007] Preferably, the support mechanism includes two sets of lead screw boxes, multiple sets of reinforcing ribs, six sets of anti-slip outriggers, and support rollers. The two sets of lead screw boxes have sliding grooves. The multiple sets of reinforcing ribs are connected and installed between the two sets of lead screw boxes. The tops of the six sets of anti-slip outriggers are respectively connected to the bottoms of the two sets of reinforcing ribs. The support rollers are installed on the multiple sets of reinforcing ribs. The operator hoists the bucket body onto the support rollers. The stability of the device is improved by setting multiple sets of reinforcing ribs, and the device is prevented from sliding by setting six sets of anti-slip outriggers.

[0008] Preferably, the clamping mechanism includes a hinge, a side connecting frame, multiple sets of guide rollers, a rotating shaft, and three sets of hydraulic cylinders. The hinge is mounted on the support roller, the side connecting frame is mounted on the hinge, the multiple sets of guide rollers are all mounted on the side connecting frame, the rotating shaft is rotatably mounted on multiple sets of reinforcing ribs, and the three sets of hydraulic cylinders are all mounted on the rotating shaft and rotatably connected to the side connecting frame. When the three sets of hydraulic cylinders are activated, they push the side connecting frame to rotate upward, clamping the side of the bucket body, which is convenient for adapting to buckets of different sizes. At the same time, the multiple sets of guide rollers facilitate the forward and backward sliding of the bucket body to adjust the welding position.

[0009] Preferably, the moving mechanism includes a dual-head motor, two sets of drive shafts, two sets of reducers, two sets of bidirectional lead screws, and four sets of sliders. The dual-head motor is mounted on a reinforcing rib. The output ends of the dual-head motor are connected to the input ends of the two sets of drive shafts, the output ends of the two sets of drive shafts are connected to the input ends of the two sets of reducers, and the output ends of the two sets of reducers are connected to the input ends of the two sets of bidirectional lead screws. The sliders are slidably installed in the sliding grooves of the lead screw box, and the sliders are connected to the bidirectional lead screws via threaded transmission. When the dual-head motor is started, it drives the two sets of drive shafts to rotate. The two sets of drive shafts drive the two sets of bidirectional lead screws to rotate through the two sets of reducers. The bidirectional lead screws drive the two sets of sliders to slide closer in the sliding grooves, thereby driving the two sets of suction mechanisms closer to the bucket body.

[0010] Preferably, the adsorption mechanism includes a support plate, an anti-slip pad, a connecting rod, three sets of cylinders, and three sets of suction cups. The support plate is installed between two adjacent sets of sliders, the anti-slip pad is installed on the support plate, the connecting rod is installed between two adjacent sets of sliders, all three sets of cylinders are installed on the connecting rod, and the three sets of suction cups are respectively installed on the three sets of cylinders. The operator places the side plate on the support plate, and the anti-slip pad increases the friction. The three sets of suction cups adsorb the side plate, and the connecting rod ensures the stability of the movement of the two sets of sliders, so that the two sets of side plates are attached to both sides of the bucket body. When the length of the bucket body is short, after the two sets of adsorption mechanisms have moved to both ends of the anti-slip legs, the three sets of cylinders can be activated to push the suction cups forward to facilitate close contact with the bucket body.

[0011] Preferably, the pressing mechanism includes a main hydraulic cylinder, a mounting base, a crossbeam, and two sets of pressing rollers. The main hydraulic cylinder is mounted on a screw box, the bottom end of the mounting base is connected to the top end of the main hydraulic cylinder, the crossbeam is rotatably mounted on the mounting base, and both sets of pressing rollers are rotatably mounted on the crossbeam. The crossbeam is rotated to one side to facilitate the hoisting of the bucket body. After the position of the bucket body is adjusted, the crossbeam is rotated to directly above the bucket body, and the main hydraulic cylinder drives the crossbeam to descend, so that the two sets of pressing rollers abut against the top end of the bucket body and fix it.

[0012] Preferably, the pressing roller is also wrapped with a rubber sleeve. The rubber sleeve has a certain elasticity. By wrapping the pressing roller with the rubber sleeve, not only can hard friction between the pressing roller and the bucket be avoided, thus protecting the bucket and the pressing roller, but the fixing effect can also be enhanced to prevent the bucket from sliding.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the workers hoist the bucket body onto the support mechanism, and the two sets of clamping mechanisms clamp the two sides of the bucket to facilitate the adaptation to buckets of different sizes. Then, the two sets of side plates are fixed on the two sets of adsorption mechanisms respectively. The moving mechanism drives the two sets of adsorption mechanisms to move closer, so that the side plates are close to the two sides of the bucket. Then, the pressing mechanism presses and fixes the bucket body, which facilitates the workers to weld it. Attached Figure Description

[0021] This utility model discloses a loader bucket welding and positioning device, including a support mechanism 01; it also includes two sets of clamping mechanisms 02, a moving mechanism 03, two sets of adsorption mechanisms 04, and a pressing mechanism 05. The two sets of clamping mechanisms 02 are mounted on the support mechanism 01 and clamp the bucket. The moving mechanism 03 is mounted on the support mechanism 01 and drives the two sets of adsorption mechanisms 04 to move. The two sets of adsorption mechanisms 04 are mounted on the moving mechanism 03 and fix the side plates. The pressing mechanism 05 is mounted on the support mechanism 01 and fixes and presses the bucket. The support mechanism 01 includes two sets of wire... The system comprises a lead screw box 11, multiple sets of reinforcing ribs 12, six sets of anti-slip support legs 13, and support rollers 14. Two sets of lead screw boxes 11 have sliding grooves. The multiple sets of reinforcing ribs 12 are connected and installed between the two sets of lead screw boxes 11. The top ends of the six sets of anti-slip support legs 13 are respectively connected to the bottom ends of the two sets of reinforcing ribs 12. The support rollers 14 are installed on the multiple sets of reinforcing ribs 12. The clamping mechanism 02 includes a hinge 21, a side connecting frame 22, multiple sets of guide rollers 23, a rotating shaft 24, and three sets of hydraulic cylinders 25. The hinge 21 is installed on the support rollers 14, the side connecting frame 22 is installed on the hinge 21, and the multiple sets of guide rollers 23 are all mounted on... On the side connecting frame 22, the rotating shaft 24 is rotatably mounted on multiple sets of reinforcing ribs 12. Three sets of hydraulic cylinders 25 are all mounted on the rotating shaft 24 and rotatably connected to the side connecting frame 22. The moving mechanism 03 includes a dual-head motor 31, two sets of transmission shafts 32, two sets of reducers 33, two sets of bidirectional lead screws 34, and four sets of sliders 35. The dual-head motor 31 is mounted on the reinforcing ribs 12. The output ends of the dual-head motor 31 are respectively connected to the input ends of the two sets of transmission shafts 32. The output ends of the two sets of transmission shafts 32 are respectively connected to the input ends of the two sets of reducers 33. The output ends of the two sets of reducers 33 are respectively connected to the input ends of the two sets of reducers 33. The input ends of two sets of bidirectional lead screws 34 are connected, and the slider 35 is slidably installed in the sliding groove of the lead screw box 11. At the same time, the slider 35 and the bidirectional lead screw 34 are connected by threaded transmission. The adsorption mechanism 04 includes a support plate 41, an anti-slip pad 42, a connecting rod 43, three sets of cylinders 44 and three sets of suction cups 45. The support plate 41 is installed between two adjacent sets of sliders 35, the anti-slip pad 42 is installed on the support plate 41, the connecting rod 43 is installed between two adjacent sets of sliders 35, the three sets of cylinders 44 are all installed on the connecting rod 43, and the three sets of suction cups 45 are respectively installed on the three sets of cylinders 44.During operation, the worker first hoists the bucket body onto the support roller 14. Multiple reinforcing ribs 12 are installed to improve the stability of the device, and six anti-slip outriggers 13 prevent slippage. Three hydraulic cylinders 25 are activated, pushing the side connecting frame 22 upwards to clamp the side of the bucket body, facilitating adaptation to buckets of different sizes. Multiple guide rollers 23 facilitate the forward and backward sliding of the bucket body to adjust the welding position. The worker then places the side plate on the support plate 41, increasing friction with anti-slip pads 42. Three suction cups 45 adhere the side plate. Connecting rod 43 ensures the stability of the movement of the two sets of sliders 35. The dual-head motor 31 is activated, driving the two sets of transmission shafts 32 to rotate. These shafts, through two sets of reducers 33, drive the two sets of bidirectional lead screws 34 to rotate. The bidirectional lead screws 34 cause the two sets of sliders 35 to slide closer together in the sliding groove, thereby causing the two sets of suction mechanisms 04 to approach the bucket body, so that the two sets of side plates adhere to both sides of the bucket body. When the bucket body is relatively short, after the two sets of suction mechanisms 04 have moved to both ends of the anti-slip legs 13, the three sets of cylinders 44 can be activated to push the suction cups 45 forward, facilitating a tight fit with the bucket body. Example 2

[0022] like Figures 1 to 5As shown, this utility model discloses a loader bucket welding positioning device based on embodiment 1. The pressing mechanism 05 includes a main hydraulic cylinder 51, a mounting base 52, a crossbeam 53, and two sets of pressing rollers 54. The main hydraulic cylinder 51 is mounted on the screw box 11, and the bottom end of the mounting base 52 is connected to the top end of the main hydraulic cylinder 51. The crossbeam 53 is rotatably mounted on the mounting base 52, and both sets of pressing rollers 54 are rotatably mounted on the crossbeam 53. The pressing rollers 54 are also wrapped with rubber sleeves. During operation, the worker first hoists the bucket body onto the support rollers 14. Multiple reinforcing ribs 12 are used to improve the stability of the device, and six anti-slip outriggers 13 are used to prevent slippage. Three sets of hydraulic cylinders 25 are activated, pushing the side connecting frame 22 upwards to clamp the side of the bucket body, facilitating adaptation to buckets of different sizes. Multiple guide rollers 23 are also used to facilitate the forward and backward sliding of the bucket body to adjust the welding position. The operator places the side plate on the support plate 41, increases friction by setting anti-slip pads 42, and uses three sets of suction cups 45 to adhere to the side plate. The connecting rod 43 ensures the stability of the movement of the two sets of sliders 35. The dual-head motor 31 is started, which drives the two sets of transmission shafts 32 to rotate. The two sets of transmission shafts 32 drive the two sets of double-sided screws 34 to rotate through the two sets of reducers 33. The double-sided screws 34 drive the two sets of sliders 35 to slide closer in the sliding groove, thereby driving the two sets of suction mechanisms 04 to approach the bucket body, so that the two sets of side plates are attached to both sides of the bucket body. When the bucket body is short, after the two sets of suction mechanisms 04 have moved to both ends of the anti-slip support legs 13, the three sets of cylinders 44 can be started to push the suction cups 45 forward to make it easier to adhere to the bucket body. After the bucket body is positioned, the crossbeam 53 is rotated to the top of the bucket body, and the main hydraulic cylinder 51 drives the crossbeam 53 to descend, so that the two sets of pressing rollers 54 abut against the top of the bucket body to fix it.
