Description

Technical Field

[0001] The present invention belongs to the technical field of workpiece adjusting devices, and specifically relates to a workpiece moving and adjusting device for welding processing of automated mechanical equipment. Background Art

[0002] Metal flexible impellers inherit the good adaptability of flexible impellers to solid particles and complex fluids, and with the advantages of metal materials, they have excellent properties such as high temperature resistance, corrosion resistance, high strength, and durability. Therefore, they show great application potential in many industries with demanding impeller performance requirements, such as petrochemical, electric power, and metallurgy. For some usage environments with low precision requirements, usually, operators will use welding to weld the blades to the hub. However, the manual welding method requires the operator to hold the welding torch by hand and align the blades with the hub before welding. And since multiple blades need to be welded on the hub, before continuous welding, due to the need for manual docking, this may cause deviations in the docking of the blades with the hub, that is, the blades may tilt, which will affect the dynamic balance performance of the impeller, resulting in additional vibration and noise during the operation of the equipment, and reducing the stability and service life of the equipment. Therefore, to solve the above problems, a workpiece moving and adjusting device for welding processing of automated mechanical equipment is proposed. Summary of the Invention

[0003] To solve the problems raised in the above background art, the present invention provides a workpiece moving and adjusting device for welding processing of automated mechanical equipment, which solves the problem that the subsequent welding of the blades is inclined due to the deviation of the blades during the docking process of the hub and the blades by manual operation.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Such as Figures 1 to 9As shown in the figure, the present invention provides a workpiece moving and adjusting device for welding and processing of automated mechanical equipment, including a workbench 1, an annular member 7 and a cascade 8. A support one 11 and a support two 12 are fixedly connected to the bottom of the workbench 1. It further includes: a clamping assembly 2, which is installed on the workbench 1 for fixing the annular member 7; a feeding assembly 4, which is arranged on the top of the workbench 1; a power assembly 3, which is installed on the top of the workbench 1 for driving the feeding assembly 4 to dock the cascade 8 placed in the feeding assembly 4 with the annular member 7; a welding arm 9, which is fixedly installed on the top of the workbench 1 for welding the docking part of the cascade 8 and the annular member 7; a transmission assembly 5, which is arranged at the bottom of the workbench 1 and can be driven by the power assembly 3 to make the clamping assembly 2 rotate unidirectionally.

[0034] The feeding assembly 4 includes a guiding frame 41 fixedly connected to the top of the workbench 1. A linear channel 411 for placing the cascade 8 and an arc-shaped channel 412 for a single cascade 8 to slide therein are arranged on the guiding frame 41. A feeding supplement assembly 44 for pushing the cascade 8 in the linear channel 411 into the arc-shaped channel 412 is also fixedly connected to the top of the workbench 1. An arc-shaped push plate 43 is slidably connected in the arc-shaped channel 412. Gear grooves 431 are equidistantly arranged on the arc-shaped push plate 43. An elastic limiting plate 42 is elastically hinged on the guiding frame 41.

[0035] The power assembly 3 includes a gear motor 31 fixedly connected to the top of the workbench 1. A rotating rod 32 is also connected to the workbench 1 by bearings. A gear member 33 meshing with the gear grooves 431 is fixedly connected to the part of the rotating rod 32 above the workbench 1. The gear motor 31 can drive the arc-shaped push plate 43 to reciprocate through the meshing of the gear member 33 and the gear grooves 431.

[0036] When one end of the cascade 8 abuts against the annular member 7, the arc surface facing the elastic limiting plate 42 disengages from the contact with the guiding frame 41.

[0037] An annular groove 13 is also opened on the workbench 1. The outer diameter of the annular member 7 is smaller than the outer diameter of the annular groove 13 and larger than the inner diameter of the annular groove 13.

[0038] The clamping assembly 2 includes a positioning column 21 connected to the workbench 1 by bearings. A cylinder 22 is fixedly connected inside the positioning column 21. A top block 23 is movably connected to the part of the positioning column 21 above the workbench 1.

[0039] The output end of the positioning column 21 is conical, and when the output end of the positioning column 21 moves upward, it can squeeze the top block 23 to move outward.

[0040] Adopting the above solution, by placing the annular part 7 on the top of the positioning post 21 and operating the cylinder 22 to extend and push the top block 23 to move to clamp the annular part 7, operating the feeding assembly 44 to push the cascade 8 in the linear channel 411 into the arc-shaped channel 412, and then driving the gear motor 31 to move the arc-shaped push plate 43 in the arc-shaped channel 412 through the meshing of the rotating rod 32 and the gear groove 431, so as to push the cascade 8 in the arc-shaped channel 412 to move. When one end of the cascade 8 abuts against the outer wall of the annular part 7, at this time, operating the welding arm 9 to weld the docking part of the cascade 8 and the annular part 7, thus avoiding the problem that the deviation of the docking of the annular part 7 and the cascade 8 affects the subsequent welding.

[0041] As Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 9 As shown, the feeding assembly 44 includes a hydraulic rod 441 fixedly connected to the top of the workbench 1. The output end of the hydraulic rod 441 is fixedly connected with a bent push plate 442 that can move in the linear channel 411. A convex surface 443 is fixedly connected to the bent push plate 442, and the bent push plate 442 abuts against the cascade 8 through the convex surface 443.

[0042] The top end of the arc-shaped push plate 43 is provided with an inclined surface 432, and the height of the bottom of the inclined surface 432 is higher than the height of the cascade 8.

[0043] Adopting the above solution, through the setting of the convex surface 443, it can ensure that the end of the cascade 8 abutting against the arc-shaped push plate 43 enters the arc-shaped channel 412 first, avoiding the situation of material jamming.

[0044] Through the design of the inclined surface 432, it can ensure that when the arc-shaped push plate 43 pushes the cascade 8 to move, the situation that the cascade 8 tilts upward can be avoided.

[0045] As Figure 2 , Figure 3 , Figure 5 and Figure 9 As shown, through holes 421 are formed in the elastic limit plate 42; the workbench 1 is provided with a locking assembly 6 for intermittently clamping into the through holes 421; the locking assembly 6 includes a spring combination rod 61 elastically connected to the workbench 1. The top of the spring combination rod 61 is fixedly connected with an inclined block 62. The bottom end of the inclined block 62 is an arc-shaped inclined surface and is movably connected above the arc-shaped channel 412. The bottom of the spring combination rod 61 extends below the workbench 1 and is fixedly connected with a connecting rod 63. The other end of the connecting rod 63 is fixedly connected with a limiting vertical rod 64. The top end of the limiting vertical rod 64 penetrates the workbench 1 and can be clamped into the bottom of the through hole 421.

[0046] The inclined block 62 has a downward trend under the pulling force of the tension spring on the spring combination rod 61, and the movement of the cascade 8 and the arc-shaped push plate 43 in the arc-shaped channel 412 can squeeze the inclined block 62 to move upward.

[0047] With the above solution, the arc-shaped push plate 43 is used to push the cascade 8 to move. One end of the cascade 8 will squeeze the inclined surface of the inclined block 62 and drive the limiting vertical rod 64 to move upward and snap into the through hole 421 through the spring combination rod 61 and the connecting rod 63, so as to ensure the stability of the welding arm 9 during the welding process after the cascade 8 is docked with the annular part 7;

[0048] When the arc-shaped push plate 43 resets, the extrusion on the inclined block 62 will be released, and the inclined block 62 will move downward and reset under the action of the pulling force of the spring combination rod 61, so as to make the limiting vertical rod 64 move downward and disengage from the through hole 421 through the connecting rod 63, so that when the annular part 7 rotates subsequently, the welded cascade 8 can be separated from the guide frame 41 and the elastic limiting plate 42 by squeezing the elastic limiting plate 42.

[0049] As Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 shown, the transmission assembly 5 includes a transmission member 51 movably sleeved on the second bracket 12. The top of the transmission member 51 is connected to the bottom of the rotating rod 32 by a bearing. The inner wall of the top of the transmission member 51 is annularly and arrayed with ratchet teeth 52. A first bevel gear 53 is fixedly sleeved at the bottom of the transmission member 51. A worm gear 56 is fixedly sleeved on the positioning column 21. A worm 54 meshing with the worm gear 56 is movably connected to the first bracket 11. One end of the worm 54 is fixedly connected with a second bevel gear 55 meshing with the first bevel gear 53;

[0050] The bottom of the rotating rod 32 is elastically connected with an elastic ratchet pawl 321 that is unidirectionally clamped with the ratchet teeth 52; A rubber ring 121 is fixedly connected to the middle of the second bracket 12 and movably sleeved outside the transmission member 51;

[0051] With the above solution, when the power assembly 3 drives the arc-shaped push plate 43 to push the cascade 8, the elastic ratchet pawl 321 will also push the cascade 8 to drive the transmission member 51 to rotate by engaging with the ratchet teeth 52. Furthermore, the positioning column 21 will be driven to rotate by a specified angle through the second bevel gear 55, the worm 54 and the worm gear 56. At the same time, the welded cascade 8 of the previous group will push the elastic limiting plate 42 to rotate and cross the elastic limiting plate 42, and the elastic limiting plate 42 will reset under its own elastic force and play a role in limiting the next group of cascades 8, so that the device can continuously work to weld the cascades 8 on the outer wall of the annular part 7 to improve the welding efficiency;

[0052] Furthermore, the reverse-running gear member 33 drives the arc-shaped push plate 43 to move reversely and reset through the cooperation of the rotating rod 32 and the gear groove 431. The reverse movement of the gear member 33 and the rotating rod 32 will drive the elastic pawl 321 to move reversely. At this time, under the action of the frictional force of the rubber ring 121 on the transmission member 51, the elastic pawl 321 will be compressed by the ratchet teeth 52 and slide relative to the ratchet teeth 52, thus avoiding the situation that the power assembly 3 drives the arc-shaped push plate 43 to reset and drives the positioning column 21 to rotate reversely through the transmission assembly 5.

[0053] Working principle and usage process of the present invention:

[0054] First, place the annular member 7 on the top of the positioning column 21 and operate the air cylinder 22 to extend and push the top block 23 to move to clamp the annular member 7. Operate the feeding assembly 44 to push the cascade 8 in the linear channel 411 into the arc-shaped channel 412. Subsequently, drive the gear motor 31 to make the arc-shaped push plate 43 move in the arc-shaped channel 412 through the meshing of the rotating rod 32 and the gear groove 431, so as to push the cascade 8 in the arc-shaped channel 412 to move. When one end of the cascade 8 abuts against the outer wall of the annular member 7, at this time, operate the welding arm 9 to weld the butt joint of the cascade 8 and the annular member 7, thus avoiding the problem that the butt joint of the annular member 7 and the cascade 8 will deviate and affect the subsequent welding.

[0055] During the process of the power assembly 3 driving the arc-shaped push plate 43 to push the cascade 8, it will also drive the transmission member 51 to rotate through the engagement of the elastic pawl 321 and the ratchet teeth 52. Then, drive the positioning column 21 to rotate a specified angle through the bevel gear II 55, the worm 54 and the worm gear 56. At the same time, the previously welded cascade 8 will push the elastic limit plate 42 to rotate and pass over the elastic limit plate 42, and the elastic limit plate 42 will reset under its own elastic force and play a role in limiting the next cascade 8, so that the device can continuously work to weld the cascade 8 on the outer wall of the annular member 7 to improve the welding efficiency.

[0056] After welding is completed, the reverse-running gear member 33 drives the arc-shaped push plate 43 to move reversely and reset through the cooperation of the rotating rod 32 and the gear groove 431. The reverse movement of the gear member 33 and the rotating rod 32 will drive the elastic pawl 321 to move reversely. At this time, the elastic pawl 321 will be compressed by the ratchet teeth 52 and slide relative to the ratchet teeth 52, thus avoiding the situation that the power assembly 3 drives the arc-shaped push plate 43 to reset and drives the positioning column 21 to rotate reversely through the transmission assembly 5, and then ensuring the accuracy when the power assembly 3 drives the arc-shaped push plate 43 to push the cascade 8 and drives the clamping assembly 2 to rotate through the transmission assembly 5 in the subsequent process.
