DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 9As shown, the present invention provides a workpiece moving and adjusting device for welding processing of automated mechanical equipment, comprising a workbench 1, an annular member 7 and a blade grid 8, wherein a bracket 11 and a bracket 2 12 are fixedly connected to the bottom of the workbench 1, and further comprising: 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 blade grid 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 point between the blade grid 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 in one direction;

[0034] The feeding assembly 4 includes a guide frame 41 fixedly connected to the top of the workbench 1, and a straight channel 411 for placing the blade 8 and an arcuate channel 412 for a single blade 8 to slide therein are provided on the guide frame 41. A feeding assembly 44 for pushing the blade 8 in the straight channel 411 into the arcuate channel 412 is also fixedly connected to the top of the workbench 1. An arcuate push plate 43 is also slidably connected in the arcuate channel 412, and gear grooves 431 are equidistantly provided on the arcuate push plate 43. An elastic limit plate 42 is also elastically hinged on the guide 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 a bearing. A gear member 33 meshing with a gear groove 431 is fixedly connected to the rotating rod 32 located 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 groove 431.

[0036] When one end of the blade 8 abuts against the annular member 7, the arc surface facing the elastic limiting plate 42 is separated from the contact with the guide frame 41;

[0037] The workbench 1 is also provided with an annular groove 13, and 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 a bearing, a cylinder 22 is fixedly connected to the interior of the positioning column 21, and a portion of the positioning column 21 located above the workbench 1 is movably connected to a top block 23;

[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] By adopting the above scheme, the annular member 7 is placed on the top of the positioning column 21 and the cylinder 22 is extended to push the top block 23 to move and clamp the annular member 7, and the feeding assembly 44 is operated to push the blade 8 in the straight channel 411 into the arc channel 412, and then the gear motor 31 is driven to move the arc push plate 43 in the arc channel 412 through the engagement of the rotating rod 32 and the gear groove 431, thereby pushing the blade 8 in the arc channel 412 to move. When one end of the blade 8 abuts against the outer wall of the annular member 7, the welding arm 9 is operated to weld the joint between the blade 8 and the annular member 7, thereby avoiding the problem of deviation in the joint between the annular member 7 and the blade 8 and affecting subsequent welding.

[0041] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Fig. 9 As shown, the feeding assembly 44 includes a hydraulic rod 441 fixedly connected to the top of the workbench 1, and the output end of the hydraulic rod 441 is fixedly connected to a bent push plate 442 that can move in the straight channel 411, and 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] An inclined surface 432 is formed at the top of the arc-shaped push plate 43 , and the height of the bottom of the inclined surface 432 is higher than the height of the blade cascade 8 .

[0043] By adopting the above solution, the convex surface 443 is provided to ensure that the end of the blade 8 abutting against the arc-shaped push plate 43 enters the arc-shaped channel 412 first, thereby avoiding the situation of material jamming.

[0044] The design of the inclined surface 432 can ensure that when the arc-shaped push plate 43 pushes the cascade 8 to move, the cascade 8 can be prevented from tilting upward.

[0045] like Figure 2 , Figure 3 , Figure 5 and Fig. 9 As shown, a through hole 421 is formed on the elastic limiting plate 42; the workbench 1 is provided with a locking assembly 6 that can be intermittently inserted into the through hole 421; the locking assembly 6 includes a spring combination rod 61 elastically connected to the workbench 1, a slanted block 62 is fixedly connected to the top of the spring combination rod 61, the bottom end of the slanted block 62 is an arc-shaped inclined surface and is movably connected to the top of the arc channel 412, the bottom of the spring combination rod 61 extends to the bottom of the workbench 1 and is fixedly connected to a connecting rod 63, the other end of the connecting rod 63 is fixedly connected to a limiting vertical rod 64, the top end of the limiting vertical rod 64 passes through the workbench 1 and can be inserted into the bottom of the through hole 421;

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

[0047] By adopting the above solution, the blade 8 is pushed to move by the arc-shaped push plate 43, and one end of the blade 8 will squeeze the inclined surface of the inclined block 62 and drive the limiting vertical rod 64 upward through the spring combination rod 61 and the connecting rod 63 to be clamped in the through hole 421, thereby ensuring the stability of the welding arm 9 during the welding process after the blade 8 and the ring member 7 are connected;

[0048] When the arc push plate 43 is reset, the squeezing of the inclined block 62 will be released, and the inclined block 62 will be reset downward under the pulling force of the spring combination rod 61, so that the limiting vertical rod 64 can be moved downward and separated from the through hole 421 through the connecting rod 63, so that when the annular member 7 rotates subsequently, the blade grid 8 after welding can be separated from the guide frame 41 and the elastic limiting plate 42 by squeezing the elastic limiting plate 42.

[0049] like Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the transmission assembly 5 includes a transmission member 51 movably sleeved on the bracket 12, the top of the transmission member 51 is connected to the bearing at the bottom of the rotating rod 32, a ratchet 52 is provided in an annular array on the inner wall of the top of the transmission member 51, a bevel gear 1 53 is fixedly sleeved on 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 bracket 11, and a bevel gear 2 55 meshing with the bevel gear 1 53 is fixedly connected to one end of the worm 54;

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

[0051] By adopting the above scheme, in the process of driving the arc-shaped push plate 43 to push the blade 8 through the power assembly 3, the elastic pawl 321 will also push the engagement with the ratchet 52 to drive the transmission member 51 to rotate, and then the bevel gear 2 55, the worm 54 and the worm wheel 56 will drive the positioning column 21 to rotate a specified angle, and at the same time, the last set of blades 8 welded 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 the action of its own elastic force and limit the next set of blades 8, so that the device can continuously work to weld the blades 8 to the outer wall of the annular member 7 to improve the welding efficiency;

[0052] Furthermore, the reverse running gear member 33 drives the arc push plate 43 to move in the opposite direction and reset through the cooperation between the rotating rod 32 and the gear groove 431, and the directional movement of the gear member 33 and the rotating rod 32 will drive the elastic pawl 321 to move in the opposite direction. At this time, through the friction force of the rubber ring 121 on the transmission member 51, the elastic pawl 321 will be squeezed and compressed by the ratchet 52 and slide relative to the ratchet 52, thereby avoiding the situation that the power component 3 drives the arc push plate 43 to reset and drives the positioning column 21 to rotate in the opposite direction through the transmission component 5.

[0053] The working principle and use process of the present invention:

[0054] First, the ring member 7 is placed on the top of the positioning column 21 and the cylinder 22 is extended to push the top block 23 to move and clamp the ring member 7. The feeding assembly 44 is operated to push the blade grid 8 in the straight channel 411 into the arc channel 412. Then, the gear motor 31 is driven to move the arc push plate 43 in the arc channel 412 through the engagement of the rotating rod 32 and the gear groove 431, thereby pushing the blade grid 8 in the arc channel 412 to move. When one end of the blade grid 8 abuts against the outer wall of the ring member 7, the welding arm 9 is operated to weld the joint between the blade grid 8 and the ring member 7, thereby avoiding the problem that the joint between the ring member 7 and the blade grid 8 will deviate and affect the subsequent welding.

[0055] In the process of the power assembly 3 driving the arc push plate 43 to push the blade 8, the elastic pawl 321 will also push the engagement with the ratchet 52 to drive the transmission member 51 to rotate, and then drive the positioning column 21 to rotate a specified angle through the bevel gear 2 55, the worm 54 and the worm wheel 56. At the same time, the last set of blades 8 welded 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 the action of its own elastic force and limit the next set of blades 8, so that the device can continuously work to weld the blades 8 to the outer wall of the ring member 7 to improve the welding efficiency;

[0056] After welding is completed, the reverse-running gear member 33 drives the arc push plate 43 to move in the opposite direction and reset through the cooperation between the rotating rod 32 and the gear groove 431, and the directional movement of the gear member 33 and the rotating rod 32 will drive the elastic pawl 321 to move in the opposite direction. At this time, the elastic pawl 321 will be squeezed and compressed by the ratchet 52 and slide relative to the ratchet 52, thereby avoiding the situation where the power component 3 drives the positioning column 21 to rotate in the opposite direction through the transmission component 5 when driving the arc push plate 43 to reset, thereby ensuring the accuracy of the subsequent power component 3 driving the arc push plate 43 to push the blade 8 when driving the clamping component 2 to rotate through the transmission component 5.
