For example, at the part connected with the impeller, there may be a specific shaft shoulder or keyway structure. The shaft shoulder is used to position the impeller to ensure the correct installation position of the impeller on the pump shaft; the keyway is matched with the key to transmit torque, so that the impeller can rotate with the rotation of the pump shaft.

One end may be a shaft coupler mounting part connected with the motor, and the structure of this part needs to ensure accurate matching with the shaft coupler. It is usually a smooth cylindrical surface and has a certain coaxiality requirement to ensure that the power output by the motor can be effectively transmitted to the pump shaft.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described below in conjunction with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0020] The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the drawings.

[0021] Referring to Figures 1 to 9 The embodiments of the present application provide a water pump shaft processing auxiliary loading device, The utility model relates to a pump shaft processing device, including the upper feeding frame 1, be equipped with the storage bin 2 on the upper feeding frame 1, the storage bin 2 with the upper feeding frame 1 between butt joint, be equipped with intermittent feeding mechanism 3 on the upper feeding frame 1, intermittent feeding mechanism 3 with the upper feeding frame 1 between rotary connection, and intermittent feeding mechanism 3 can drive the position intermittent movement of pump shaft and feed, be equipped with pump shaft alignment structure 4 on the upper feeding frame 1 to the pump shaft and carry out alignment, the side of upper feeding frame 1 is equipped with processing frame 7, be equipped with pump shaft moving mechanism 5 between the upper feeding frame 1 and processing frame 7 to the pump shaft and carry out horizontal movement, be equipped with pump shaft adjustment mechanism 6 on the processing frame 7, pump shaft adjustment mechanism 6 with pump shaft moving mechanism 5 between butt joint.

[0022] Need to explain that processing frame 7 is equipped with the machining center to the pump shaft and carry out processing.

[0023] Specifically, intermittent feeding mechanism 3 includes two pump shaft feeding pieces that are symmetrically arranged on the upper feeding frame 1, the pump shaft feeding piece includes a drive motor 31, a feeding plate 32, two drive shafts 33 and two drive plates 34, the drive motor 31 is located on the upper feeding frame 1, the two drive shafts 33 are rotatably connected to the upper feeding frame 1, the drive motor 31 is in transmission connection with one of the drive shafts 33, the two drive plates 34 are respectively connected to the two drive shafts 33, a drive belt 35 is arranged between the two drive shafts 33, and the two ends of the feeding plate 32 are respectively connected to the two drive plates 34, a plurality of equidistantly arranged circular grooves 36 are arranged on the feeding plate 32.

[0024] When feeding the pump shaft, the two ends of the pump shaft are located in the semicircular placing groove 11 of the upper feeding frame 1, then the drive motor 31 is driven to rotate the drive shaft 33 on the upper feeding frame 1, and the other drive shaft 33 can be driven to rotate on the upper feeding frame 1 through the drive belt 35, the synchronous rotation of the two drive shafts 33 can drive the two drive plates 34 to rotate, thereby driving the feeding plate 32 to reciprocatingly move forward and backward in the space of the upper feeding frame 1, so that the circular grooves 36 on the upper feeding frame 1 bear the bottom of the pump shaft, and the pump shaft can be intermittently fed under the driving of the feeding plate 32. The intermittent feeding provides time for accurate clamping and positioning after each feeding, and compared with continuous feeding, the intermittent feeding can carefully adjust and position the material after each feeding, for example, when milling the keyway on the pump shaft, the accurate positioning after the intermittent feeding can ensure that the position accuracy of the keyway is within ±0.05mm, thereby effectively avoiding the decline of the machining accuracy caused by the accumulation of slight deviation in the continuous feeding process.

[0025] Specifically, the storage bin 2 is provided with a partition plate 21 arranged obliquely, a spacing space 22 is arranged between the partition plate 21 and the storage bin 2, the partition plate 21 is provided with a sliding plate 23 connected therewith, the partition plate 21 is provided with a first electric cylinder 24, the telescopic end of the first electric cylinder 24 is connected with the sliding plate 23, and the sliding plate 23 is provided with two symmetrically arranged sliding rods 25 which are in sliding fit with the partition plate 21.

[0026] After the pump shaft is placed in the storage bin 2, the pump shafts that need to be fed can be moved to the feeding rack 1 one by one through the spacing space 22 between the partition plate 21 and the storage bin 2, so as to realize the spacing and continuity of feeding the pump shafts. The first electric cylinder 24 drives the sliding plate 23 to slide on the partition plate 21 through the two sliding rods 25, so as to control the size of the spacing space 22. In the process of feeding the pump shafts of different diameters, the size of the spacing space 22 can be controlled according to the diameters of the pump shafts, so that only one pump shaft can be fed at a time during feeding, so that the subsequent pump shafts can be arranged in order during feeding.

[0027] Specifically, the pump shaft alignment structure 4 comprises a first alignment frame 41 and a second alignment frame 42, the first alignment frame 41 and the second alignment frame 42 are symmetrically arranged at the positions on both sides of the discharge end of the feeding rack 1, the first alignment frame 41 is provided with a horizontally arranged alignment electric cylinder 43, and the telescopic end of the alignment electric cylinder 43 is provided with an alignment plate 44.

[0028] When the pump shaft moves to the space between the first alignment frame 41 and the second alignment frame 42 on both sides of the feeding rack 1 through the two pump shaft feeding members, the alignment electric cylinder 43 drives the alignment plate 44 to move horizontally in the first alignment frame 41, so that the pump shaft is in the middle alignment position during conveying. When the pump shaft needs to be machined into multiple shaft sections with different diameters and there is a strict length requirement between the shaft sections, such as the length tolerance between adjacent shaft sections being within ±0.1mm, the alignment during feeding can ensure the accuracy of the starting position of each machining, so as to accurately control the length of each shaft section and improve the size consistency of the product. The alignment during feeding can help to ensure the coaxiality and straightness of the pump shaft and the shape and position accuracy. The clamping operation will be more smooth and rapid, and the operator does not need to spend extra time to adjust the misaligned pump shaft.

[0029] Specifically, the pump shaft moving mechanism 5 comprises a moving plate 51, a lifting electric cylinder 52, a lifting frame 53 and two electric sliding tables 54, the two electric sliding tables 54 are symmetrically arranged on the feeding rack 1, the two ends of the moving plate 51 are connected with the moving ends of the two electric sliding tables 54 respectively, the lifting electric cylinder 52 is located at the bottom of the moving plate 51, the lifting frame 53 is located on the moving plate 51 and the bottom of the lifting frame 53 is connected with the telescopic end of the lifting electric cylinder 52, and the lifting frame 53 is provided with two symmetrically arranged moving clamping paws 55.

[0030] When the pump shaft is moved and conveyed to the processing position, the two electric sliding tables 54 work to move the positions of the two moving clamping paws 55 to the lower side of the pump shaft, then the lifting electric cylinder 52 works to drive the lifting frame 53 to move upward, so that the positions of the two moving clamping paws 55 are moved upward to the lower side of the pump shaft, the pump shaft is clamped by the work of the two moving clamping paws 55, then the two electric sliding tables 54 work to drive the moving plate 51 to work, so that the pump shaft on the feeding rack 1 is horizontally moved to the processing rack 7, for subsequent processing work of the pump shaft.

[0031] Specifically, the pump shaft adjusting mechanism 6 comprises an up-down adjusting structure 61, an angle adjusting structure 62 and a spacing adjusting structure 63, the up-down adjusting structure 61 is arranged on the processing rack 7, the angle adjusting structure 62 is located on the moving end of the up-down adjusting structure 61, and the spacing adjusting structure 63 is located on the angle adjusting structure 62 and is in sliding fit with the angle adjusting structure 62.

[0032] Specifically, the up-down adjusting structure 61 comprises a sliding plate 611 and two vertically arranged vertical sliding tables 612, the two vertical sliding tables 612 are symmetrically arranged at the two sides of the processing rack 7, the two ends of the sliding plate 611 are connected with the moving ends of the two vertical sliding tables 612 respectively, the bottom of the sliding plate 611 is provided with a rotary motor 613, the main shaft of the rotary motor 613 is provided with a rotary plate 614, and the rotary plate 614 rotates on the sliding plate 611.

[0033] In this embodiment, during the clamping of the pump shaft, the rotary motor 613 works to make the positions of the two adjusting clamping paws 633 be located at one side of the moving clamping paw 55, when the pump shaft is moved to the side of the two adjusting clamping paws 633 by the two electric sliding tables 54, the pump shaft is clamped by the two adjusting clamping paws 633; When the pump shaft is processed, the rotary motor 613 works to drive the rotary plate 614 to rotate by 180 degrees, so that the pump shaft is located at the center of the processing center, for subsequent processing work of the pump shaft by the processing center; During the machining of the pump shaft by the machining center, the position of the pump shaft is driven to rotate and rotate by the working of the rotating motor 613, so that different positions of the pump shaft are docked with the machining center, and different positions of the pump shaft can be machined during machining of the pump shaft.

[0034] Then the sliding plate 611 is driven to move upward by the working of the two vertical sliding tables 612, and the position of the pump shaft is moved to the machining center.

[0035] Specifically, the angle adjusting structure 62 comprises an adjusting motor 621, an adjusting screw rod 622 and an adjusting plate 623. The adjusting motor 621 is located on the rotating plate 614. The adjusting screw rod 622 is rotationally connected to the rotating plate 614 and is in transmission connection with the main shaft of the adjusting motor 621. The adjusting screw rod 622 is provided with an adjusting block 624 in threaded connection. One end of the adjusting plate 623 is rotationally connected to the rotating plate 614. The two ends of the adjusting block 624 are provided with rotationally connected adjusting rods 625. The adjusting rods 625 are hinged to the bottom of the adjusting plate 623.

[0036] In this embodiment, when the position of the loaded pump shaft is adjusted, the adjusting motor 621 drives the adjusting screw rod 622 to rotate on the rotating plate 614, thereby driving the adjusting block 624 to move horizontally on the adjusting screw rod 622, and thereby driving the adjusting plate 623 to rotate around the rotating plate 614 through the two adjusting rods 625, so as to adjust the angular position of the adjusting plate 623, so that the end of the pump shaft fixed on the two adjusting jaws 633 is adjusted in inclination angle, and when the pump shaft is specially turned or ground, the angular position of the pump shaft and the machining center can be adjusted as needed for better machining of the pump shaft. After the end of the pump shaft is machined, the rotating motor 613 drives the rotating plate 614 to rotate by 180 degrees, and then the adjusting plate 623 changes in angle on the rotating plate 614, so that the other end of the pump shaft is adjusted in inclination angle and then moved to the machining center for machining work. During machining of the pump shaft, the position of the pump shaft during loading can be adjusted according to the needs of machining, and the angular position of the pump shaft can be adjusted. Different shaft sections and surfaces may require different machining processes. Angular changes allow each part of the pump shaft to be presented to the machining tool at the best angle, ensuring that each surface can be efficiently and accurately machined. When machining shaft sections of different diameters and lengths on the pump shaft, appropriate angular changes can reduce the influence of machining force and thermal deformation on dimensional accuracy.

[0037] Specifically, the spacing adjustment structure 63 comprises an adjustment motor 631, two adjustment blocks 632 and two adjustment clamps 633, the adjustment plate 623 is provided with two symmetrically rotatingly connected adjustment wheels 634, an adjustment belt 635 is arranged between the two adjustment wheels 634, the adjustment motor 621 is arranged at the bottom of the adjustment plate 623 and is drivingly connected with the adjustment wheels 634, the two adjustment blocks 632 are symmetrically arranged at one end of the top of the adjustment plate 623, the adjustment blocks 632 are slidingly connected with the adjustment plate 623, and the two adjustment clamps 633 are respectively horizontally connected with the two adjustment blocks 632.

[0038] In the embodiment, when the pump shaft is clamped, the adjustment motor 631 is driven to rotate the two adjustment wheels on the adjustment plate 623, which drives the adjustment belt 635 to rotate, thereby driving the two adjustment blocks 632 to move on the adjustment plate 623, so as to change the spacing between the two adjustment clamps 633. On the one hand, when the spacing between the two adjustment clamps 633 is adjusted during the processing of pump shafts of different sizes, the pump shafts of different sizes can be adapted to, and the diameter and shape of the pump shafts can have multiple specifications. By adjusting the spacing between the clamps 633, the outer diameter of the pump shaft can be accurately matched, so that the clamps are tightly attached to the surface of the pump shaft. On the other hand, the irregularly shaped pump shaft can be clamped. When the pump shaft surface has a keyway, the spacing between the clamps can be adjusted to avoid the keyway, so that the clamps can stably clamp the cylindrical part of the pump shaft, avoiding damage to the pump shaft during clamping and ensuring stable clamping effect. On the other hand, uniform stress avoids damage, and appropriate adjustment of the spacing between the clamps 633 can make the clamping force of the clamps evenly distributed on the pump shaft. If the spacing between the clamps is not appropriate, the clamping force may be concentrated on some points on the surface of the pump shaft. If the spacing is too small, the clamps may generate local excessive pressure on the surface of the pump shaft, causing indentation or scratches on the surface of the pump shaft. After the spacing is correctly adjusted, the clamping force can be evenly distributed, protecting the surface finish of the pump shaft. When the pump shaft is processed, the clamping position can be adjusted to process the clamped position.

[0039] Specifically, the upper frame 1 is provided with a semicircular placement groove 11 for moving the pump shaft; when the pump shaft is intermittently fed, the two pump shaft feeding members are operated to move the pump shaft horizontally forward in the corresponding semicircular placement groove 11 of the upper frame 1 and feed the pump shaft.
