Description

Technical Field

[0001] The utility model relates to the technical field of water pump assembly equipment, in particular to a deep well pump stator press assembly machine. Background Art

[0002] During deep-well pump assembly, the assembled stator and coil must be placed on the upper end of the pump barrel, and then press-fitted into the barrel using a press-fitting machine. Currently, however, this is typically done manually, after the stator and coil are placed on the upper end of the barrel, they are then press-fitted into the barrel using a press-fitting tool.

[0003] The following problems still exist in the prior art:

[0004] 1. Because the stator is similar in size to the inner diameter of the pump barrel, when workers place the stator and coil on the pump barrel, the stator may deviate from the axis of the pump barrel, resulting in the stator not being fully aligned with the pump barrel. If press-fitting is performed at this time, the bottom end of the stator will not enter the pump barrel, which can easily cause damage to the stator or deformation of the pump barrel during the press-fitting process.

[0005] 2. During the press-fitting process, the press-fitting mechanism needs to apply sufficient force to the stator to ensure that the stator is pressed tightly into the pump barrel. However, since the stator and coil will generate friction with the inner wall of the pump barrel during the press-fitting process, the pump barrel will be subjected to excessive pressure and cause deformation, affecting the quality of the product.

[0083] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0084] like Figures 1-4A deep well pump stator press assembly machine is shown, comprising:

[0085] Rack 1;

[0086] A pump body fixing mechanism 2 is provided on the frame 1 and is used to fix the pump barrel 5;

[0087] The coil straightening mechanism 3 is used to fix the stator. The coil straightening mechanism 3 is arranged above the pump body fixing mechanism 2 to keep the stator coaxial with the pump barrel 5;

[0088] The press-fitting mechanism 4 is arranged above the coil straightening mechanism 3 , and is used to press-fit the stator into the pump barrel 5 .

[0089] During the assembly of the deep well pump, the stator and the coil wound on the stator need to be placed into the pump barrel 5 of the deep well pump. During assembly, the stator and the coil usually need to be placed on the upper end of the pump barrel 5 first, and then the stator and the coil need to be press-fitted into the pump barrel 5.

[0090] Currently, this process is generally performed manually, so in actual operation, the stator and pump barrel are often not fully aligned. This can easily cause the pump barrel to be squeezed and deformed during the subsequent press-fitting process, or the stator cannot be properly installed in the pump barrel, affecting product quality.

[0091] This technical solution is achieved by setting up a pump body fixing mechanism 2 and a coil straightening mechanism 3. The pump body fixing mechanism 2 is used to clamp and fix the position of the pump barrel 5. The coil straightening mechanism 3 can further clamp and fix the stator and can straighten the stator, making it convenient to keep the stator and the pump barrel 5 on the same axis, so that the pressing mechanism 4 can press the stator into the pump barrel 5.

[0092] Among them, the pump body fixing mechanism 2 includes:

[0093] a fixed mold mounting plate 213 on which the fixed mold 211 is mounted;

[0094] A movable mold mounting plate 214 on which the movable mold 212 is mounted;

[0095] The reset clamping assembly is used to drive the movable mold mounting plate 214 to move toward the fixed mold mounting plate 213, and close the fixed mold 211 and the movable mold 212 to form a loading position 210, which is used to fix the pump barrel 5.

[0096] The opening assembly 13 is used to drive the movable mold mounting plate 214 away from the fixed mold mounting plate 213 and separate the fixed mold 211 and the movable mold 212 to facilitate the placement of the pump barrel 5.

[0097] Specific as Figure 3-Figure 5 As shown, the fixed mold 211 is formed with a fixed mold groove 1 218; the movable mold 212 is formed with a fixed mold groove 219;

[0098] The inner sides of the fixed mold groove 1 218 and the fixed mold groove 2 219 are both protruded with a protruding strip 1 24 , and the circumferential side of the pump barrel 5 is concavely formed with an annular recess 1 51 .

[0099] A positioning protrusion 25 is protruded from the fixed mold 211, and a positioning groove 26 is recessed into the movable mold 212. When the movable mold mounting plate 214 approaches the fixed mold mounting plate 213, the positioning protrusion 25 can be inserted into the positioning groove 26 to facilitate alignment between the fixed mold 211 and the movable mold 212.

[0100] Specific as Figure 5 As shown, as a preferred embodiment, the positioning protrusion 25 and the positioning groove 26 are trapezoidal, so as to facilitate alignment between the positioning protrusion 25 and the positioning groove 26.

[0101] When the fixed mold 211 and the movable mold 212 are close together and closed, the fixed mold groove 1 218 and the fixed mold groove 219 form a loading position 210. The convex strip 1 24 on the fixed mold groove 1 218 and the convex strip 1 24 on the fixed mold groove 219 can form a convex ring and be placed in the annular recess 1 51.

[0102] Since the size of the stator and coil is generally slightly larger than the inner diameter of the pump barrel 5, it is necessary to use the press-fitting mechanism 4 to press-fit the stator and coil into the interior of the pump barrel 5. If the stator and coil cannot be kept on the same axis as the pump barrel 5, then during the press-fitting process, the stator and coil will be pressed into the pump barrel 5.

[0103] During the press-fitting process, the press-fitting mechanism 4 applies a significant force to the stator and coils, forcing them into the pump barrel 5. The stator and coils rub against the interior of the pump barrel 5, causing downward pressure on the pump barrel 5, which can easily cause deformation. If the stator and coils are not aligned with the pump barrel 5, the press-fitting mechanism 4 can easily squeeze and bend the pump barrel 5.

[0104] In this technical solution, by providing a coil straightening mechanism 3 , the stator, the coil and the pump barrel 5 can be kept on the same axis, so that the press-fitting mechanism 4 can perform press-fitting.

[0105] And through the cooperation between the annular recess 51 and the ridge 24, the ridge 24 can provide an additional support point when the pump barrel 5 is under pressure, thereby maintaining the shape of the pump barrel 5 and preventing the pump barrel 5 from being squeezed and deformed.

[0106] As another preferred embodiment, a second annular recess 52 is formed at the bottom end of the pump barrel 5 , and a second convex strip 27 is protruded from the inner sides of the bottom ends of the first fixed die groove 218 and the second fixed die groove 219 .

[0107] When the fixed mold 211 and the movable mold 212 are closed to form the loading position 210, the convex strip 27 on the fixed mold groove 1 218 and the convex strip 27 on the fixed mold groove 219 can form a convex ring and be placed in the annular recess 2 52, thereby fixing the bottom end of the pump barrel 5 to prevent a large reaction force from being generated between the bottom of the pump barrel 5 and the bottom of the loading position 210 during press-fitting, causing the pump barrel 5 to deform.

[0108] like Figures 1-4 As shown, the reset clamping assembly includes:

[0109] A guide post 215, one end of which is fixed to the movable mold mounting plate 214, and the other end of the guide post 215 passes through the fixed mold mounting plate 213;

[0110] A guide post connecting plate 216 connected to one end of the guide post 215 extending from the fixed mold mounting plate 213;

[0111] The elastic member 217 is sleeved on the outside of the guide post 215 , and two ends of the elastic member 217 respectively abut against the guide post connecting plate 216 and the fixed mold mounting plate 213 .

[0112] The guide pillars 215 can further determine the moving route of the movable mold mounting plate 214 , so that the movable mold mounting plate 214 can drive the movable mold 212 to accurately cooperate with the fixed mold 211 .

[0113] The elastic member 217 enables the movable mold mounting plate 214 to move along the guide column 215 and approach the fixed mold mounting plate 213, so that the movable mold 212 and the fixed mold 211 are closed, thereby clamping and fixing the pump barrel 5.

[0114] like Figures 1-4 As shown, the opening component 13 includes:

[0115] The ejector cylinder 131 is mounted on the fixed plate 14 on the frame 1;

[0116] The ejecting push plate 132 is connected to the end of the ejecting cylinder 131.

[0117] The ejection cylinder 131 can drive the ejection push plate 132 to lean against the guide column connecting plate 216, and push the guide column connecting plate 216 through the ejection push plate 132, thereby driving the movable mold mounting plate 214 to move, thereby achieving the purpose of moving the movable mold 212 away from the fixed mold 211.

[0118] When the movable mold 212 is away from the fixed mold 211 , the pump barrel 5 can be placed in the fixed mold 211 , and after the fixed mold 211 and the movable mold 212 are closed, the pump barrel 5 is fixed in the loading position 210 .

[0119] like Figures 1-6 As shown, the coil straightening mechanism 3 includes:

[0120] The clamping assembly 31 includes a clamping cylinder 36. When the clamping cylinder 36 drives the clamping jaws thereon to move inward, a clamping portion 32 is formed between the clamping jaws of the clamping cylinder 36. The clamping portion 32 is used to fix the stator and the coil so that the stator and the coil remain coaxial with the pump barrel 5.

[0121] The lifting assembly 33 is used to drive the clamping assembly 31 to move in the vertical direction, so that the coil straightening mechanism 3 can adjust the position of the clamping assembly 31 according to the height of the pump barrel 5 actually being processed, to ensure that the clamping assembly 31 can fix the stator and the coil at the upper end of the pump barrel 5, so as to facilitate the pressing mechanism 4 to perform the pressing action.

[0122] A mounting bracket 15 is formed on the frame 1, and a top plate 16 is provided on the top of the mounting bracket 15;

[0123] The lifting assembly 33 includes:

[0124] A lifting plate 34, on which the clamping assembly 31 is disposed;

[0125] The driving motor 1 35 is provided on the top plate 16 . The driving motor 1 35 is used to drive the lifting plate 34 to rise or fall, thereby driving the clamping assembly 31 to rise or fall.

[0126] like Figures 1-6 As shown, the press-fitting mechanism 4 includes:

[0127] A pressing die 43, which is used to perform the pressing action;

[0128] The pressing cylinder 41 is used to drive the pressing die 43 to move;

[0129] The pressing limit plate 42 and the pressing mold 43 are arranged on the pressing limit plate 42 .

[0130] The mounting bracket 15 also includes a polished rod 17, the upper end of which is connected to the top plate 16, and the pressing limit plate 42 is slidably arranged on the polished rod 17, and the polished rod 17 can limit the moving direction of the pressing limit plate 42.

[0131] The lifting plate 34 of the coil straightening mechanism 3 is connected to the top plate 16 through the second polished rod 18, and the pressing limit plate 42 is connected to the top plate 16 through the first polished rod 17, so as to facilitate the position determination between the pressing mold 43 and the clamping assembly 31 and complete the alignment.

[0132] like Figure 1 As shown, a dividing plate 11 is provided on the frame 1 , a plurality of support plates 12 are provided on the dividing plate 11 , and the fixed mold mounting plate 213 is fixed on the support plates 12 .

[0133] A fixing plate 14 is further provided on the frame 1 , and the opening assembly 13 is provided on the fixing plate 14 . The fixing plate 14 is provided above the indexing plate 11 , and the fixing plate 14 will not be driven by the indexing plate 11 .

[0134] After the pump barrel 5 is loaded into the loading position 210 on the indexing plate 11, the indexing plate 11 drives the pump barrel 5 in the loading position 210 through the material pressing position and the code scanning position in sequence, and then enters the material withdrawal position. Therefore, at least four opening components 13 are provided on the fixing plate 14. When the pump barrel 5 is deformed or damaged, the operator can use the opening components 13 to open the loading position 210 at different positions to facilitate the removal of the pump barrel 5.

[0135] like Figures 1-8 As shown, since the support plate 12 is arranged on the dividing plate 11, in order to provide sufficient supporting force for the support plate 12 during press-fitting, a support assembly 6 is provided under the support plate 12 to avoid the support plate 12 from breaking or bending during the press-fitting process, which affects the efficiency of the press-fitting and improves the yield rate.

[0136] The support assembly 6 comprises:

[0137] a support core 61 for resting against the lower end surface of the support plate 12;

[0138] A push cylinder 62 is used to drive the support core 61 to move;

[0139] The support column 63 has an active cavity 631 formed therein, and the upper end of the active cavity 631 is connected to the extension hole 632 .

[0140] The support core 61 is formed with a narrow diameter section 612 and a wide diameter section 611. The wide diameter section 611 is movably arranged in the movable cavity 631. The narrow diameter section 612 is inserted into the extension hole 632. When the wide diameter section 611 moves to the top of the movable cavity 631, the support core 61 reaches the maximum stroke.

[0141] A support portion 65 is provided on the support plate 12 . An upper nut 66 and a lower nut 67 are sleeved on the support portion 65 . The upper nut 66 and the lower nut 67 clamp the support plate 12 .

[0142] By pushing the cylinder 62 and the support column 63 together, the support core 61 can extend upward from the support column 63 and abut against the lower end of the support plate 12 .

[0143] Furthermore, the pushing cylinder 62 is connected to a pushing bar 64 , and the upper end surface of the pushing bar 64 is formed with a low-position abutting surface 641 and a high-position abutting surface 642 , and a pushing inclined surface 643 is formed between the low-position abutting surface 641 and the high-position abutting surface 642 .

[0144] A through hole 633 is formed on the side wall of the active cavity 631 , and a through slot 613 is formed on the wide diameter section 611 . The through hole 633 is aligned with the through slot 613 , and the pushing cylinder 62 drives the pushing bar 64 to pass through the through hole 633 and enter the active cavity 631 .

[0145] A boosting surface 614 and a supporting surface 615 are formed on the upper end surface of the through groove 613 , and the boosting surface 614 is connected to the supporting surface 615 .

[0146] When the pushing inclined surface 643 contacts the boosting surface 614, it can drive the supporting core 61 to move upward;

[0147] When the pushing slope 643 separates from the boosting surface 614 and the supporting surface 615 contacts the high-position abutting surface 642, the position of the supporting core 61 can be fixed, even if the upper end of the supporting core 61 abuts against the lower end of the supporting portion 65, so that the supporting core 61 can support the supporting plate 12.

[0148] As a preferred embodiment, a reinforcing pad 19 is provided at the lower end of the mounting bracket 15, and the support assembly 6 is provided on the reinforcing pad 19, so as to facilitate the alignment between the support assembly 6 and the pump body fixing mechanism 2 located at the press-fit position.

[0149] like Figure 1 and Figure 2 As shown, the pump body fixing mechanism 2 further includes a second ejection cylinder 22 , and a second ejection push plate 23 is provided at the end of the second ejection cylinder 22 .

[0150] When the press-fitting operation is about to be performed, the press-fitting mechanism 4 exerts a large force on the stator and coil below, causing the pump barrel 5 to move downward. However, since the bottom end of the pump barrel 5 is fixed, the pump barrel 5 cannot move downward, resulting in outward expansion deformation, which in turn causes the pump barrel 5 to deform and become unusable.

[0151] By setting up the ejection cylinder 22 to drive the ejection push plate 23 to rest against the movable mold mounting plate 214, and push the movable mold mounting plate 214 toward the fixed mold mounting plate 213, the movable mold 212 can be prevented from separating from the fixed mold 211, thereby improving the fixing effect of the pump body fixing mechanism 2 on the pump barrel 5.

[0152] like Figure 1 and Figure 9 As shown, a code scanning mechanism 7 is also provided on the frame 1;

[0153] The outer shell of the pump barrel 5 is provided with a product code setting opening 53 for setting the product code. The code scanning mechanism 7 is used to identify the product code to record the process that the product has gone through.

[0154] The code scanning mechanism 7 includes a rotating assembly 71 and a code scanning element 73;

[0155] The rotating assembly 71 includes:

[0156] Drive motor 2 72;

[0157] The rotating arm 74 is connected to the second driving motor 72, and the second driving motor 72 can drive the rotating arm 74 to rotate;

[0158] The mounting base 75 is disposed on the rotating arm 74 , and the mounting base 75 is used to mount the code scanning component 73 .

[0159] The mounting base 75 is driven by the rotating arm 74 to bypass the outer periphery of the pump barrel 5 so that the code scanning component 73 can accurately enter the product code.

[0160] The code scanning mechanism 7 also includes a lifting component 2 76, which can drive the rotating component 71 to move up and down, thereby adjusting the height of the rotating component 71 and the code scanning element 73 to facilitate matching pump bodies of different heights and specifications for code scanning.
