Description

Technical Field

[0001] The invention relates to the technical field of pump processing equipment, in particular to a feeding system for producing a pump body shell. Background Art

[0002] Pumps are everywhere in people's lives and have a serious impact on people's lives. The pump casing collects the pressure water thrown out by the impeller, and then guides the pressure water to the discharge port of the water pump; reduces the speed of the pressure water, converts the kinetic energy of the water flow into pressure energy; and connects the fixed parts of the water pump into one to form the pump stator. In the prior art, after casting the pump casing, it is generally divided into two types: pure manual processing and equipment processing. However, the pure manual processing method is most affected by human factors, resulting in low processing efficiency; therefore, a feeding system is used in conjunction with the pump casing processing equipment for production. The process also requires the semi-finished product to be transported to the next equipment to complete the processing of the pump casing in sequence. This is the mainstream production method of the existing pump casing, but the pump casing needs to complete the processing and production process in sequence and requires fixed-point feeding. If unqualified or other situations are encountered during the sequential processing stage, the processing time of the established steps will be changed, and the feeding system cannot perform corresponding self-adjustment, affecting the production efficiency of the pump casing.

[0039] Combine the following Figure 1-Figure 10 The feed system for producing a pump casing according to the present invention is described.

[0040] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig.10 As shown, in one embodiment, a feeding system for producing a pump housing includes: a frame 100 and two conveyor belts 200, first mechanical arms 300 are evenly distributed on both sides of the frame 100, collecting hoppers 210 are arranged on opposite sides of the two conveyor belts 200, second mechanical arms 220 are arranged on opposite sides of the two collecting hoppers 210, and material distribution platforms 110 are fixedly connected on both sides of the frame 100, and material feed ports 120 are provided at the opposite positions of the material distribution platforms 110 and the frame 100, a placing bucket 130 is provided at the bottom end of one of the material distribution platforms 110 on one side, and through ports are provided on the other sides of the other material distribution platforms 110;

[0041] The conveying mechanism 400 includes two mounting frames 410, which are mounted on the bottom of the frame 100. A power mechanism 460 is provided in the middle recess of the frame 100. Two groups of driven rollers 430 are rotatably connected to the top groove of the frame 100. The ends of the driven rollers 430 are rotatably connected to the inner wall of the frame 100. A power roller 420 is rotatably connected to the inner wall of the mounting frame 410. A conveyor belt 450 is provided on the surface of a group of driven rollers 430 and the power roller 420. The power roller 420 is provided on the inner wall of the conveyor belt 450.

[0042] The material placing tray 230 is installed at the top of the frame 100 and is located above the conveyor belt 450;

[0043] Multiple feeding trays 240 are evenly placed on the upper surface of the conveyor belt 450 .

[0044] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the power mechanism 460 includes an installation box 461, the installation box 461 is fixedly connected to the frame 100, a servo motor 462 is fixedly installed on the inner wall of the installation box 461, a power shaft 463 is rotatably connected to the inner wall of the installation box 461, both ends of the power shaft 463 are provided with a one-way bearing 4610, and the other end of the one-way bearing 4610 is provided with a transmission rod 465, a connecting rod 4611 is fixedly connected between the two power rollers 420, and a reciprocating screw is rotatably connected to the inner wall of the installation box 461 466, the other end of the transmission rod 465, the surface of the connecting rod 4611 and the surface of the reciprocating screw 466 are all fixedly connected with the second bevel gear 467, the output shaft of the servo motor 462 and the surface of the power shaft 463 are all fixedly connected with the first bevel gear 464, the surface of the reciprocating screw 466 is provided with two sliding blocks 468, the lower end of the surface of the sliding block 468 is fixedly connected with a cross bar 469, the other end of the cross bar 469 passes through the installation box 461 and is fixedly connected with a push plate 4613.

[0045] In this embodiment, the servo motor 462 is started to rotate forward, and the two one-way bearings 4610 rotate in different directions. Under the action of the lower one-way bearing 4610, the two second bevel gears 467 and the connecting rod 4611 below are driven to operate, thereby driving the two power rollers 420 to operate at the same time, driving the conveyor belt 450 to operate, and the two driven rollers 430 rotate adaptively under the condition of friction, driving the feeding plate 240 on the surface of the conveyor belt 450 to operate. When it is necessary to feed the material to the distribution table 110 at a fixed point, the servo motor 462 is reversed, and under the action of the upper one-way bearing 4610, the upper transmission rod 465 rotates synchronously with the power shaft 463. Under the action of the two second bevel gears 467 above, the reciprocating screw 466 rotates in place, thereby driving its surface The sliding block 468 moves, and under the limiting action of the cross bar 469 and the two push rods 4612, it moves longitudinally and horizontally, driving the push plate 4613 to contact the feed tray 240, and utilizing the adsorption effect of the electric suction cup 4614 to transport different feed trays 240 to the corresponding material distribution table 110, and cooperate with the first robot arm 300 to complete the entry of new materials from the feed tray 240 to the material distribution table 110 and the output of processed materials. Through the forward and reverse rotation of the servo motor 462, the separate operation of feeding or conveying in the conveying mechanism 400 is driven. When the first robot arm 300 does not finish feeding, its conveying part will not run. When there are fewer errors in different workstations, there is no need to repeatedly adjust the conveying components of the feeding system, and its feeding and conveying are carried out alternately.

[0046] like Figure 3 , Figure 4 and Figure 5 As shown, two push rods 4612 are fixedly connected at the connection between the cross bar 469 and the push plate 4613. The two push rods 4612 and the cross bar 469 are overall in a "U" shape. The push plate 4613 is in a "mountain" shape. Electric suction cups 4614 are provided at three protrusions on the other side of the push plate 4613.

[0047] In this embodiment, the two push rods 4612 and the cross bar 469 form a "mountain" shape as a whole, and the push rod 4612 and the installation box 461 are in a through relationship. Therefore, the push plate 4613 can be effectively limited so that the push plate 4613 can better contact the feeding tray 240, and its electric suction cup 4614 can adsorb the feeding tray 240, so that when feeding, the push plate 4613 and the feeding tray 240 are more closely connected, and there will be no position deviation, making the feeding more accurate.

[0048] like Figure 5 As shown, the reciprocating screw 466 is provided with two thread grooves of the same pitch and opposite rotation direction in two sections. The middle part of the reciprocating screw 466 is a round rod-shaped connecting part, and the second bevel gear 467 is fixedly connected to the surface of the connecting part.

[0049] In this embodiment, the second bevel gear 467 is arranged at its connecting portion and will not affect the normal rotation of the reciprocating screw 466. The movement of the reciprocating screw 466 and the sliding block 468 is an existing well-known technology and will not be elaborated on. When the reciprocating screw 466 rotates, the sliding block 468 will make axial reciprocating motion on its surface.

[0050] like Figure 1 , Figure 6 and Figure 7 As shown, the feed tray 240 includes an outer frame 241 and a placement frame 242. The placement frame 242 is rotatably connected inside the outer frame 241. The placement frame 242 is rotatably connected to one end that passes through the outer frame 241 and is fixedly connected to a circular gear 243. A rack 244 meshing with the circular gear 243 is slidably connected to a recess on one side of the outer frame 241. A plurality of arc-shaped protrusions 2410 are fixedly connected to the surface of the outer frame 241.

[0051] In this embodiment, the material on the material tray 230 will directly enter the placement frame 242, and the conveyor belt 450 will complete the transportation of the entire feed tray 240 by moving its outer frame 241. When feeding the overflow hole distribution platform 110, the rack 244 will be squeezed against the inner wall of the distribution platform 110, and the rack 244 will move, driving the circular gear 243 and the placement frame 242 to rotate synchronously, and finally completing the 360-degree rotation of the placement frame 242. During the rotation process, the pump body casing falls into the corresponding placement bucket 130. For other distribution platforms 110 that do not need to be turned over, the end of the rack 244 will pass through the through-hole without being hindered or reversed, making the feeding system more precise and adaptable, effectively improving its transportation production efficiency, and after the rotation itself, it does not affect the normal discharge operation of the overflow hole distribution platform 110.

[0052] like Figure 7 As shown, one end of the rack 244 is fixedly connected to a limiting bevel tooth plate 245, a fixing plate 246 is fixedly connected to a recess on one side of the outer frame 241, the bottom end of the fixing plate 246 is fixedly connected to a first spring 248, the top end of the fixing plate 246 is slidably connected to a limiting rod 247, the end of the limiting rod 247 passes through the fixing plate 246 and the first spring 248 in sequence and is fixedly connected to a limiting tooth block 249 used in conjunction with the limiting bevel tooth plate 245, and the other end of the first spring 248 is fixedly connected to the limiting rod 247.

[0053] In this embodiment, the rack 244 will synchronously drive the limiting bevel tooth plate 245 to move when it moves. Under the mutual influence of the shapes of the limiting bevel tooth plate 245 and the limiting tooth block 249, the rack 244 moves unidirectionally without assistance. The limiting tooth block 249 is affected by the shape and will move up and down reciprocatingly during this process. It is also unidirectionally limited, so that the overflow hole drilling and material distribution table 110 will be more stable and will not rotate when discharging materials. Later, if it is necessary to release the lock, lift the limiting rod 247 upward to disengage the limiting bevel tooth plate 245 and the limiting tooth block 249, and reset the rack 244.

[0054] like Figure 1 , Figure 6 , Figure 8 and Fig. 9 As shown, the material placing tray 230 includes a discharge barrel 231, two sealing plates 234 and two guide blocks 233. The discharge barrel 231 is fixedly connected to the top of the frame 100, and the two sealing plates 234 are located below the discharge barrel 231. The sealing plates 234 are fixedly connected to the bottom ends of the sealing plates 234. The two guide blocks 233 are distributed in an "eight" shape, and a second spring 232 is fixedly connected between the opposite sides of the two guide blocks 233 and the inner wall of the frame 100.

[0055] In this embodiment, when the conveyor belt 450 drives the feeding tray 240 to operate, under the action of the "eight"-shaped guide block 233, the two guide blocks 233 will move outward, and the second spring 232 will bend under force, thereby driving the two sealing plates 234 to be in an open state. Under the action of gravity and shape, the pump body shell in the discharge barrel 231 automatically enters the feeding tray 240 to complete the automated unloading operation. At the same time, the protruding block 2410 can reduce the friction between the outer frame 241 and the guide block 233. At the same time, the positioning plate 451 can also increase the stability of the feeding tray 240 on the surface of the conveyor belt 450, and a medium pressure sensor can also be built into the sealing plate 234 to provide data support for the operation of the second robotic arm 220. It uses the trend of the feeding tray 240 moving on the conveyor belt 450 to automatically complete the unloading operation and improve the conveying efficiency of the feeding system.

[0056] like Figure 1 , Figure 8 and Fig. 9 As shown, the opposite sides of the two guide blocks 233 are fixedly connected with a second connecting rod 236, the other end of the second connecting rod 236 is inserted with the first connecting rod 235, the other end of the first connecting rod 235 extends out of the frame 100, and the first connecting rod 235 and the frame 100 are fixedly connected.

[0057] In this embodiment, the second connecting rod 236 and the first connecting rod 235 cooperate with each other to limit the guide block 233 to prevent it from being affected by the second spring 232 during operation.

[0058] As shown Fig. 9 in FIG. [FIG. number not provided], two vertical plates 237 are fixedly connected to the middle of the bottom end of the material discharging cylinder 231, and the height of the vertical plates 237 is the same as the height of the sealing plate 234.

[0059] In this embodiment, the two vertical plates 237 limit the final position of the sealing plate 234 to avoid the situation where the two ends are inconsistent and affect the sealing effect.

[0060] As shown Figure 2 and Figure 3 in FIG. [FIG. number not provided], two auxiliary rollers 440 are rotatably connected to the inner wall of the mounting frame 410. The two auxiliary rollers 440 and the driving roller 420 are arranged in a triangular pattern within the mounting frame 410, and the surface of the auxiliary rollers 440 is in contact with the conveyor belt 450. The surface of the conveyor belt 450 is provided with evenly distributed positioning plates 451, and the positioning plates 451 are made of rubber material.

[0061] In this embodiment, when the conveyor belt 450 is transporting, due to the influence of its frictional force, the auxiliary rollers 440 will automatically rotate. Under the action of the two auxiliary rollers 440, the two driven rollers 430 and the driving roller 420, the running path of the conveyor belt 450 can be presented in a "T" shape, increasing the running stability of the conveyor belt 450.

[0062] Working principle: Place qualified products after appearance inspection on the conveyor belt 200, use its collecting hopper 210 to temporarily place the raw materials, use the second mechanical arm 220 to place the pump body shell into the discharge barrel 231 of the material placement tray 230, start the servo motor 462 to rotate forward, the two one-way bearings 4610 rotate in different directions, and the lower one-way bearing 4610 drives the two second bevel gears 467 and the connecting rod 4611 to run, thereby driving the two power rollers 420 to run, driving the conveyor belt 450 to run, and the two driven rollers 430 to run. Under the condition of friction, the feeding tray 240 on the surface of the conveyor belt 450 is driven to rotate adaptively, and when the feeding tray 240 moves to the bottom of the material placement tray 230, the opening at the bottom of the material placement tray 230 is opened to discharge the material automatically. When the conveyor belt 450 moves, when the feeding tray 240 that has completed material placement is separated from the material placement tray 230, the opening at the bottom of the material placement tray 230 is automatically closed. Before the new feeding tray 240 arrives, the second mechanical arm 220 is used to complete the placement of the pump body shell in the material placement tray 230, and the material placement tray 230 completes the automatic discharge of the feeding tray 240 The servo motor 462 is operated and cooperates with the conveyor belt 450 to transport the material feeding tray 240 to the corresponding material distribution platform 110. At this time, the servo motor 462 is reversed, and under the action of the upper one-way bearing 4610, the upper transmission rod 465 rotates synchronously with the power shaft 463. Under the action of the two second bevel gears 467 above, the reciprocating screw 466 rotates in situ, thereby driving the sliding block 468 on its surface to move. Under the limiting action of the cross bar 469 and the two push rods 4612, it moves longitudinally and horizontally, driving the push plate 4613 to contact the feeding tray 240, and By utilizing the adsorption effect of the electric suction cup 4614, different feeding trays 240 are transported to the corresponding material distribution table 110, and the first robot arm 300 is cooperated to complete the picking of the placing tray 230, and the pump body shell processed in the step-by-step workstation is placed in to complete the replacement. The servo motor 462 continues to reverse, and the push plate 4613 is driven by the reciprocating screw 466 to reset, and the adsorption force of the electric suction cup 4614 is utilized to return the feeding tray 240 that has completed the material replacement to its original position again, and again cooperate with the conveyor belt 450 to carry out this reciprocating feeding process.

[0063] It should be noted that, according to the production of the cast pump shell, people perform shape inspection and size inspection, produce standard data and tolerance requirements, store the standard data and tolerance requirements in the control terminal, and perform appearance inspection. It should be noted that this is a well-known technical means in this field. After the inspection is completed, the pump shell can be placed on the conveyor belt 200 for transportation and processing in steps;

[0064] When the feed plate 240 feeds the material from the feed distribution table 110 through the overflow hole drilled, the rack 244 will be squeezed against the inner wall of the feed distribution table 110, and the rack 244 will move, driving the circular gear 243 to rotate, and finally completing a 360-degree rotation of the placement frame 242. During the rotation, the pump body shell falls into the corresponding placement bucket 130. For other feed distribution tables 110 that do not need to be turned over, the end of the rack 244 will pass through the through-hole without being hindered, so no reversal will occur.

[0065] In the above description, the first robotic arm, the second robotic arm, the servo motor, the electric suction cup, the one-way bearing, etc. are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the first robotic arm, the second robotic arm, the servo motor, and the electric suction cup can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
