[0043] Refer to the instruction manual Figure 1-3 , an automatic assembly device for the impeller shaft of a self-priming pump according to an embodiment of the present invention, the impeller shaft of the self-priming pump comprises a shaft 9 and an impeller 10 detachably mounted on one end of the shaft 9, the impeller 10 comprises an impeller core column and an impeller disk fixedly sleeved on the outer side of the impeller core column, a plurality of blades uniformly distributed in an annular shape are fixedly arranged on one side of the impeller disk, and two arc-shaped shell covers 11 for docking and assembling the shaft 9 and the impeller 10 are fixedly connected between the opposite ends of the outer sides of the shaft 9 and the impeller core column by locking bolts;

[0044] Annular grooves are provided on the outer sides of the opposite ends of the shaft rod 9 and the impeller core column, and arc blocks are fixedly provided at both ends of the inner sides of the two arc-shaped shell covers 11, wherein the axial cross-sections of the annular grooves and the arc blocks are both set to be isosceles trapezoids, which helps to automatically correct the snapping position smoothly when position deviation occurs during the buckling of the two arc-shaped shell covers 11, and ensures that the mounting holes on the two arc-shaped shell covers 11 are aligned, and magnetic strips are fixedly embedded in the middle of the opposite sides of the two arc-shaped shell covers 11, wherein the magnetic properties of the magnetic strips on the two arc-shaped shell covers 11 are set oppositely , the two arc-shaped shell covers 11 after buckling can be pre-limited to ensure the smooth progress of the subsequent tightening bolt process. A key slot is provided at one end of the shaft rod 9, and a key block adapted to the key slot is fixedly provided at one end of the impeller core shaft close to the shaft rod 9. The arrangement of the key slot and the key block can ensure that the shaft rod 9 and the impeller 10 can rotate stably and synchronously after docking. The above-mentioned assembly method of the impeller shaft of the self-priming pump can effectively avoid the loosening of the docking position of the shaft rod 9 and the impeller 10, and can also ensure the accuracy of the docking of the shaft rod 9 and the impeller 10;

[0045] The automatic assembly device is used for automatically assembling the shaft 9, the impeller 10 and the arc-shaped shell cover 11. The automatic assembly device comprises a frame 1. A shaft supply mechanism 2 for automatically supplying the shaft 9 and an impeller supply mechanism 4 for automatically supplying the impeller 10 are provided at the top middle of the frame 1. A shell cover supply mechanism 3 for automatically supplying the arc-shaped shell cover 11 and fastening the shaft 9 and the opposite ends of the impeller core column is provided between the shaft supply mechanism 2 and the impeller supply mechanism 4.

[0046] The impeller supply mechanism 4 is composed of a deflection material taking part for automatically taking the impeller 10 and a shifting part for driving the taken impeller 10 to switch the position;

[0047] A running groove 6 is provided in the middle of one end of the frame 1, and a mechanical arm 5 for fixing two buckled arc-shaped shell covers 11 with upper bolts is fixedly installed at the position of the deflection material-collecting part at the bottom of the frame 1, and sink grooves 7 are provided at positions on both sides of the running groove 6 at one end of the top of the frame 1, and conveyor belts 8 for conveying the finished impeller shaft are installed inside the two sink grooves 7.

[0048] It should be noted that the present invention realizes intermittent supply of the shaft 9, the arc-shaped shell cover 11 and the impeller 10 by utilizing the coordinated use of the shaft supply mechanism 2, the shell cover supply mechanism 3 and the impeller supply mechanism 4, and in the process of docking the shaft 9 with the impeller core shaft, the two arc-shaped shell covers 11 are automatically fastened together synchronously. At the same time, in the process of the next round of docking and fastening action, the locking bolt is clamped by the robot arm 5 to lock and fix the impeller shaft that has completed the docking and fastening, and the assembled finished impeller shaft is conveyed to the next process through the conveyor belt.

[0049] Specifically, Figure 1 and Figure 4-5 As shown, the shaft supply mechanism 2 includes two brackets 21 fixed on the top of the frame 1, a shaft box 22 and a support plate 23 located at the bottom of the shaft box 22 are fixedly connected between the two brackets 21, a push column 24 is slidably installed between the support plate 23 and the shaft box 22, and a U-shaped groove 25 is opened at one end of the top of the push column 24, wherein the depth and the width of the feeding end of the U-shaped groove 25 are equal to the diameter of the shaft 9, so that the shaft 9 falling into the U-shaped groove 25 is used to support the upper shaft, ensuring that the upper shaft 9 to be dropped will not hinder the lateral pushing process of the push column 24, an electric push rod 26 is fixedly installed at the middle of the bottom of the support plate 23, a convex block 27 is fixedly provided at the middle of the bottom of one end of the push column 24, and the telescopic end of the electric push rod 26 is fixedly connected to the convex block 27;

[0050] The shaft supply mechanism 2 also includes a motor slot 210 opened at the top of the push column 24 and through slots 28 opened on both sides of the push column 24 and connected to the U-shaped slot 25. Rubber rollers 29 are rotatably installed in the two through slots 28, and a driving motor for driving the corresponding rubber rollers 29 to rotate is fixedly installed in the motor slot 210.

[0051] It should be noted that, in the process of intermittent supply of the shaft 9, the control end controls the electric push rod 26 to pull the protrusion 27 to reciprocate, so that the shaft inside the shaft box 22 intermittently falls into the U-shaped groove 25, and is pushed to the docking and fastening station to complete the plugging with the impeller core shaft. Since the keyway at the end of the shaft 9 and the key block at the end of the target impeller core shaft may not be correctly aligned during the process of the shaft 9 falling into the U-shaped groove 25, the electric push rod 26 is used to control the shaft 9 to move back and forth, so that the shaft inside the shaft box 22 intermittently falls into the U-shaped groove 25, and is pushed to the docking and fastening station to complete the plugging with the impeller core shaft. In the process of pulling the push column 26 to bring the target shaft 9 closer to the docking and fastening station, the corresponding rubber roller 29 can be driven to rotate by the driving motor, and the rotating rubber roller 29 can be used to drive the shaft 9 to be plugged in the U-shaped groove 25 to rotate, so that the keyway at the end of the shaft 9 and the key block at the end of the impeller core shaft can complete the automatic alignment and plug-in process. After the key block at the end of the impeller core shaft is inserted into the keyway at the end of the shaft 9, the rubber roller 29 is idle relative to the fixed shaft.

[0052] Specifically, Figure 1 and Figure 6 As shown, the shell cover supply mechanism 3 includes a bracket 21 fixed on both sides of the frame 1 and a T-shaped push bar 313 fixed at the bottom of one end of the push column 24, a shell cover box 32 is fixedly arranged on the top of the bracket 21, an electric push rod 23 is fixedly installed on the outer side of one end of the shell cover box 32, the telescopic part of the electric push rod 23 extends to the end inside the shell cover box 32 and is fixedly connected with a push plate, and a material opening is opened on the top of the shell cover box 32, wherein a groove for stacking the arc-shaped shell covers 11 can be added at the two openings of the top of the shell cover box 32 (not specifically drawn in the drawings), and the arc-shaped shell covers 11 that fall into the shell cover box 32 one by one are pushed to the shell cover material taking station by the push plate that reciprocates under the action of the electric push rod 23;

[0053] The shell cover supply mechanism 3 also includes two slide grooves 34 opened on the top of the frame 1, and U-shaped slides 35 are slidably installed inside the two slide grooves 34. The tops of the two U-shaped slides 35 are provided with alternating feeding components, and the alternating feeding components include a rotating shaft 37 rotatably installed on the top of the inner side of the U-shaped slide 35, and a swing seat is fixedly provided in the middle of the outer side of the rotating shaft 37. A servo motor for driving the corresponding rotating shaft 37 to rotate is fixedly installed on the outer side of the U-shaped slide 35, and adsorption arc plates 39 are fixedly connected at both ends of the swing seat;

[0054] A reset feed assembly is provided at the top of the frame 1 corresponding to each U-shaped slide 35. The reset feed assembly includes a vertical plate 311 and an L-shaped stop frame 36 fixed to the top of the frame 1, and a spring 2 312 is fixedly connected between the vertical plate 311 and the corresponding U-shaped slide 35;

[0055] The swing seat is composed of a square column fixedly sleeved in the middle of a rotating shaft 37 and movable plates 38 arranged on both sides of the square column. A slot is provided in the middle between the opposite ends of the two movable plates, and holes are provided on the inner sides of the two slots. Rods corresponding to the corresponding holes are provided on both sides of the square column, and one end of the rod is movably inserted into the corresponding hole, wherein the number of rods in each slot is set to two or more to ensure that the movable plate 38 will not rotate relative to the square column, and a spring 310 is sleeved on the outer side of each rod for fixedly connecting the corresponding movable plate 38 and the square column, and the top end of the L-shaped retaining frame 36 is movably fitted with the outer side of the corresponding movable plate 38, wherein when the spring 1 310 and the spring 2 312 are in a natural state, the movable plate 38 and the U-shaped slide seat 35 are respectively in the following positions. Figure 2 As shown in the position, the L-shaped retaining frame 36 just fits with the inclined surface of the outer side of the movable plate 38 at the corresponding position close to one end of the adsorption arc plate 39.

[0056] It should be noted that, in the process of intermittently supplying the arc-shaped shell cover 11, the control end is used to control the electric push rod 2 33 to push the push plate to reciprocate, and the arc-shaped shell cover 11 falling into the shell cover box 32 is intermittently pushed to the shell cover material taking station, that is, Figure 6 In the state shown by the swing seat, whenever the swing seat is turned 180° under the drive of the corresponding servo motor, the corresponding electric push rod 2 33 will drive the push plate to push the arc-shaped shell cover 11 inside the shell cover box 32 to contact the adsorption arc plate 39 close to the shell cover box 32, and use the adsorption arc plate 39 to suck it, waiting for the next round of switching to the docking and fastening station to complete the plug-in state limitation of the shaft rod 9 in the plug-in state and the impeller core shaft;

[0057] In the process of using the electric push rod 1 26 to pull the push column 24 to bring the target shaft rod 9 closer to the docking and fastening position, the T-shaped push strip 313 will move closer to the docking and fastening position together with the push column 24. When the T-shaped push strip 313 contacts the vertical plate 311 during the advancement, the T-shaped push strip 313 that continues to advance will push the U-shaped slide 35 to move along the corresponding slide groove 34 and stretch the corresponding spring 2 312. At the same time, in the process of the U-shaped slide 35 moving along the corresponding slide groove 34, due to the obstruction of the L-shaped stop frame 36, the movable plate 38 in contact with the L-shaped stop frame 36 will gradually move closer to the docking and fastening position as the U-shaped slide 35 moves, and The corresponding spring 310 is stretched along the direction of the insertion rod, so that the two arc-shaped shell covers 11 clamp the shaft 9 and the impeller core shaft that have been plugged in, and the suction state of the adsorption arc plate 39 on the corresponding arc-shaped shell cover 11 is released. Then, when the electric push rod 26 pulls the push column 24 back to load the next round of shaft 9, the corresponding movable plate 38 is reset under the action of the spring 310, and flipped 180° under the drive of the servo motor, and enters the material picking station to wait for the adsorption of the arc-shaped shell cover 11 that is about to be pushed out. The other adsorption arc plate 39 that has completed material picking will be switched to the docking and locking station to wait for the next round of locking and limiting of the shaft 9 and the impeller core shaft that have been plugged in.

[0061] The transfer part also includes a trapezoidal block 2 413 fixed to the outside of one end of the U-shaped plate 47 close to the second rotating shaft 43 and a clamping member arranged on the outside of the corresponding side frame 42. The middle of both sides of the U-shaped plate 47 are fixed with trapezoidal blocks 420, and the top of the frame 1 is located at both sides of the U-shaped plate 47. The position of the trapezoidal block 1 411 is fixed. When the T-shaped push bar 313 is in the initial state (such as Figure 8 As shown), the trapezoidal block 420 on the left side of the U-shaped plate 47 and the opposite side of the trapezoidal block 1 411 are in a fitted state, so as to ensure that the rack 49 and the gear ring 4122 can smoothly contact the limiting state of the positioning member on the rotating shaft 2 43 while maintaining the vertical coplanar state;

[0062] The locking member includes a square groove 416 provided on the end surface corresponding to the second rotating shaft 43 and a limiting groove 418 extending through one side of the corresponding side frame 42, a locking column 415 is movably inserted inside the square groove 416, a trapezoidal block three 417 is movably inserted inside the limiting groove 418, a side plate 414 is fixedly connected between one end of the locking column 415 located outside the square groove 416 and one end of the trapezoidal block three 417 located outside the corresponding side frame 42, and a spring four 419 is fixedly connected between the side plate 414 and the corresponding side frame 42, wherein, when the spring four 419 is in a natural state, the end of the locking column 15 away from the side plate 414 is located inside the square groove 416 inserted on the second rotating shaft 43, and the trapezoidal block three 417 extends through the limiting groove 418 to one end of the corresponding side frame 42 and contacts with the U-shaped plate 47.

[0063] It should be noted that when the impeller 10 is intermittently supplied, the electric push rod 1 26 is used to pull the push column 24 to move the target shaft 9 closer to the docking and fastening station, and the T-shaped push bar 313 that moves synchronously with the push column 24 is used to push the U-shaped plate 47 to move. During this period, as the U-shaped plate 47 moves, the trapezoidal block 2 413 on its outer side will move forward synchronously, and under the restriction of the trapezoidal block 420 and the trapezoidal block 1 411 on the other side of the U-shaped plate 47, the forward trapezoidal block 2 413 is used to squeeze the trapezoidal block 3 417, so that the trapezoidal block 3 417 moves along the limiting groove 418 toward the side plate 414, and the spring 419 is stretched, so that the clamping column 415 gradually disengages from the square groove 416 on the rotating shaft 2 43. When the clamping column 415 is completely disengaged from the square groove 416, the rack 49 and the gear ring 412 also start to enter a state of meshing.

[0064] At this time, the side of the trapezoidal block 2 413 away from the U-shaped plate 47 and the side of the trapezoidal block 3 417 away from the side plate 414 are just in contact with each other, and then as the trapezoidal block 2 413 continues to advance, the synchronously moving rack 49 will drive the gear ring 412 to rotate, so that the adsorption plate 444 at the current position sucking the impeller 10 rotates with the disc 441, and when the rack 49 and the gear ring 412 are just released from the meshing state, the rotating shaft 2 43 is just driven by the rack 49 to rotate 90 degrees, so that the impeller 10 can be taken out of the conveying chute. The impeller 10 that has been brought out enters the docking and fastening station to wait for docking with the shaft 9. At the same time, the side of the trapezoidal block 420 that is in contact with the trapezoidal block 1 411 is just released from the contact state, so that the side plate 414 in this state moves closer to the side frame 42 under the restoring force of the spring 419, so that the clamping column 415 is again clamped into the square groove 416 on the rotating shaft 2 43. At the same time, the side of the trapezoidal block 2 413 that is away from the U-shaped plate 47 and the side of the trapezoidal block 3 417 that is away from the side plate 414 are just out of contact.

[0065] Then, as the U-shaped plate 47 continues to move, its right side (refer to Figure 8) will gradually contact the trapezoidal block 1 411 on the corresponding side, and be pushed to the left by the trapezoidal block 1 411, so that the U-shaped plate 47 moves to the left synchronously under the cooperation restriction of the limiting guide groove 410 and the I-shaped block 48, so that the gear ring 412 and the rack 49 in a vertical coplanar state are completely staggered. In this process, the movement stroke of the U-shaped plate 47 is fitted with the stroke of the two arc-shaped shell covers 11 moving toward each other, that is, when the trapezoidal block 420 on the right side gradually starts to contact the trapezoidal block 1 411 on the corresponding side, the T-shaped push strip 313 will be in contact with the U The U-shaped slide 35 contacts and pushes the U-shaped slide 35 to move along the corresponding slide groove 34, and the aforementioned arc-shaped shell cover 11 snaps together. After completion, the electric push rod 1 26 pulls the push column 24 to reset and load the next round of shaft rod 9. During this process, the U-shaped plate 47 that is reset synchronously with the T-shaped push bar 313 will use the trapezoidal block 1 411 to push the corresponding trapezoidal block 420 to the right under the restriction of the trapezoidal block 420 and the trapezoidal block 1 411 on its left side, so that the U-shaped plate 47 returns to its original position, and the rack 49 will then enter a state of being vertically coplanar with the gear ring 412;

[0066] Moreover, each time it rotates 90°, the impeller 10 at the impeller picking station will be switched to the docking and snap-fitting station to wait for the connection with the shaft rod 9, and the impeller shaft that has completed the docking and snap-fitting will be sent to the bolting station, and the bolts will be tightened by the robot arm 5 to complete the locking of the two arc-shaped shell covers 11. Subsequently, the adsorption plate 444 will release the adsorption state, and the finished impeller shaft will fall onto the conveyor belt 8 and be transported to the next process.
