Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically, it demonstrates an oiling mechanism for motor rotor shafts. Background Technology

[0002] The motor rotor shaft is the rotating component in a motor. It is a device used to convert electrical energy into mechanical energy and mechanical energy into electrical energy. The rotor shaft consists of a central rotor and rods that pass through both sides of the rotor.

[0003] When the aforementioned rotor shaft is in use, lubricating oil needs to be applied to the end of the rod furthest from the rotor. However, in related technologies, the application of lubricating oil to the rod is done manually by workers. During the application process, workers can only apply the amount of lubricating oil based on their subjective feeling, resulting in different amounts of lubricating oil applied to each rod. The quality of manual oil application cannot be controlled, the uniformity is poor, and it is very easy to miss or apply the oil incompletely. In addition, it is a waste of human resources. Utility Model Content

[0004] The purpose of this invention is to provide an oiling mechanism for motor rotor shafts, which has a simple and practical structure and a high degree of automation.

[0005] The technical solution is as follows:

[0006] An oiling mechanism for a motor rotor shaft, wherein the rotor shaft is composed of a central rotor and two side rods, the oiling mechanism comprising:

[0007] The material rack has several spaced supports arranged side by side. The supports are used to place the rotor shaft in a horizontal position and to make the rods on both sides of the rotor shaft extend outward.

[0008] At least one set of injectors, the injectors are connected to an external oil pumping device through oil pipes, and several spaced oil nozzles are arranged side by side below the injectors. The arrangement of the oil nozzles is consistent with the placement direction of the rotor shaft, and the oil nozzles spray the rod part of the rotor shaft.

[0009] The rolling drive structure is connected to the injector on a lifting assembly. The lifting assembly drives the rolling drive structure and the injector to move up and down relative to the feed rack. The rolling drive structure includes a drive member, a pair of synchronous pulleys driven by the drive member, and a synchronous belt between the pair of synchronous pulleys. The lower surface of the synchronous belt is used to make frictional contact with the rotor shaft to make the rotor shaft on the support roll.

[0010] In addition, the above embodiments of this utility model may also have the following additional technical features:

[0011] According to one embodiment of this utility model, a lifting cylinder is connected to the lower center of the material rack, and shafts are provided on both sides of the lower part of the material rack. The shafts are movably inserted into a sleeve, and the sleeve and the lifting cylinder are connected to a base plate. The lifting cylinder can drive the material rack to move up and down. When unloading material, the material rack can be lowered to a height that is easy to operate, and when spraying oil, it can be raised to the working height, so that the height of the material rack is adjustable.

[0012] In one embodiment, the base plate is laterally movably mounted on a base frame. A guide rail is provided on the surface of the base frame, and a slider is movably connected to the guide rail via a snap-fit ​​mechanism. The slider is connected to the base plate. A push-pull cylinder is also provided on the base frame, and the drive end of the push-pull cylinder is connected to the base plate. Through the guide rail-slider mechanism, the entire feed rack (along with its rotor shaft) can move horizontally, aligning the rotor shaft rod with the fuel injectors vertically, ensuring that each fuel injector is aligned with its rod.

[0013] According to one embodiment of the present invention, the support includes a pair of mirror-symmetrical side plates, with a recessed support groove in the middle of the top of the side plates. The mirror-symmetrical side plate structure is simple and reliable, and the recessed support groove in the middle of the top of the side plates can naturally accommodate and support the rod portion of the rotor shaft.

[0014] According to one embodiment of this utility model, the lifting assembly includes a frame, on which a lifting cylinder is mounted. The drive end of the lifting cylinder is connected downward to a mounting plate. The rolling drive structure and the fuel injector are mounted on the mounting plate. A guide rod and guide sleeve assembly is provided between the frame and the mounting plate. The lifting cylinder, as an actuator, provides power for the overall lifting and lowering of the fuel injector and the rolling drive structure, ensuring that the synchronous belt can contact the rotor shaft and that the fuel injector nozzle is aligned with the rod portion of the rotor shaft.

[0015] According to one embodiment of the present invention, the rolling drive structure further includes a tensioning pulley disposed above the pair of synchronous pulleys, with the upper surface of the synchronous belt passing over the tensioning pulley. The tensioning pulley is used to adjust and maintain the tension of the synchronous belt, thereby maintaining the tension of the synchronous belt.

[0016] According to one embodiment of the present invention, the tip of the nozzle is flat and tilted. This forms a slightly angled fan-shaped spray pattern, which can cover a wider spray area on the rod, helping to improve the coverage efficiency of a single spray and enhance uniformity.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Multiple rotor shafts can be placed on the material rack at one time, enabling batch oiling and improving production efficiency. The support seat ensures that the rotor shafts can be placed stably and the rods are fully exposed, which is conducive to subsequent oiling and rolling operations.

[0019] 2. The number and arrangement of the oil nozzles directly correspond to the position of the rotor shaft on the material rack, ensuring that each shaft can be accurately sprayed with oil and avoiding missed coating. Moreover, the oil sprayer can control the amount and pressure of lubricating oil delivered to the oil nozzles, solving the problem of inconsistent oil volume caused by manual oiling based on feeling.

[0020] 3. The rotor shaft rotates on the support by friction driven by the rolling drive structure, which enables the oil injector to spray the entire circumferential surface of the rod evenly, improving the coating uniformity. Moreover, the working height of the rolling drive structure and the oil injector can be adaptively adjusted to ensure effective rolling and accurate oil spraying. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model embodiment proposes an oiling mechanism for a motor rotor shaft, which mainly includes a material rack 1, an oil injector 3, and a rolling drive structure 4.

[0028] See Figure 1As shown, the material rack 1 is arranged horizontally, and several spaced supports 2 are arranged side by side on the top surface of the material rack 1, that is, the several supports 2 are arranged in an array. The rotor shaft is placed on the supports 2. The supports 2 are used to make the rotor shaft lie horizontally and to allow the rods on both sides of the rotor shaft to extend outward. That is to say, the placement direction of the rotor shaft is perpendicular to the extension direction of the material rack in space.

[0029] See Figure 1 As shown, in this embodiment, two sets of parallel, spaced-apart injectors 3 are arranged above the material rack 1. The injectors 3 are connected to an external oil pumping device, such as a metering pump, via oil pipes. Several spaced-apart nozzles 31 are arranged side by side on the bottom surface of the injectors 3. In this embodiment, each injector 3 has four nozzles 31. The arrangement of the four nozzles 31 is consistent with the orientation of the rotor shaft. The four nozzles 31 spray the rotor shaft rod, that is, each side of the rotor shaft rod can correspond to a pair of nozzles, and the two nozzles cover the entire spraying area of ​​one side of the rod.

[0030] See Figure 2 As shown, the rolling drive structure 4 and the injector 3 are connected to a lifting assembly 5. The lifting assembly 5 drives the rolling drive structure 4 and the injector 3 to move up and down relative to the material rack 1. The rolling drive structure 4 includes a drive member 41, a pair of synchronous pulleys 42 driven by the drive member 41, and a synchronous belt 43 located between the pair of synchronous pulleys 42. The lower surface of the synchronous belt 43 is used to make frictional contact with the rotor shaft to make the rotor shaft on the support roll. That is to say, during the descent of the rolling drive structure, the lower surface of the synchronous belt on it can simultaneously abut against the top surface of the rotor in the middle of several rotor shafts. During the operation of the synchronous belt, its frictional contact with the rotor will cause the rotor shaft on the support to rotate, so that the injector can uniformly spray the entire circumferential surface of the rod, avoiding dead corners or missed areas that may exist in manual application.

[0031] During operation: Several rotor shafts are usually laid horizontally on the support seat 2 of the material rack 1 by personnel; the lifting component 5 is activated, so that the rolling drive structure 4 and the oil injector 3 move downwards to approach the material rack 1 together until the lower belt surface of the synchronous belt 43 contacts the rotor top surface of the rotor shaft; the drive component 41 of the rolling drive structure 4 is activated, so that the synchronous belt 43 begins to slowly and uniformly drive the rotor to rotate synchronously and slowly; the oil pumping equipment of the external oil injector 3 is activated to control the amount and pressure of lubricating oil delivered to the oil nozzle 31, so that the oil mist is evenly sprayed onto the outer circumferential surface of the rod.

[0032] See Figure 1As shown, a lifting cylinder 61 is connected to the lower center of the material rack 1. Shafts 62 are installed on both sides of the lower part of the material rack 1. The shafts 62 are movably inserted into a sleeve 63. The sleeve 63 and the lifting cylinder 61 are connected to a base plate 6. The lifting cylinder can drive the material rack to move up and down. When unloading material, the material rack can be lowered to a height that is easy to operate. When spraying oil, it can be raised to the working height, realizing the height adjustment of the material rack. This ensures that the rotor on the rotor shaft maintains good contact with the synchronous belt of the rolling drive structure, and that the rod and the oil nozzle are at the optimal spraying distance. In addition, it can also provide an adjustment means to adapt to different specifications of rotor shaft (mainly rotor diameter). The shafts and sleeves constitute a guide mechanism to ensure that the material rack rises and falls smoothly and vertically under the drive of the lifting cylinder, preventing shaking or tilting and ensuring the stability of the rotor shaft position.

[0033] Based on the above technical solution, the base plate 6 can be movably mounted laterally on a base frame 7. A guide rail 71 is provided on the surface of the base frame 7, and a slider 72 is movably connected to the guide rail 71 via a snap-fit ​​mechanism. The slider 72 is connected to the base plate 6. A push-pull cylinder 73 is also provided on the base frame 7, and the drive end of the push-pull cylinder 73 is connected to the base plate 6. Through the guide rail and slider mechanism, the entire material rack (along with its rotor shaft) can move horizontally, achieving adjustable lateral position of the material rack. This ensures that the rod of each rotor shaft is vertically aligned with the fuel injector, guaranteeing that the rod of each rotor shaft can stop directly below the fuel injector, facilitating mass production.

[0034] See Figure 3 As shown, the mounting base 2 includes a pair of mirror-symmetrical side plates 21, with a mounting groove 22 recessed in the middle of the top of the side plates 21. The mirror-symmetrical side plate structure is simple and reliable. The recessed mounting groove in the middle of the top of the side plates can naturally accommodate and support the rod part of the rotor shaft. The mounting groove can usually be designed as a V-shape or arc shape, which helps the rotor shaft to automatically align when placed, reduces manual adjustment time, ensures that the position of each rotor shaft is relatively consistent, which is beneficial for subsequent oil spraying and rolling drive. Moreover, the design of the mounting groove allows the rod parts on both sides of the rotor shaft to be completely suspended and extended without obstruction after placement, which is convenient for oil spraying.

[0035] See Figure 2 As shown, the lifting assembly 5 includes a frame 51, on which a lifting cylinder 52 is mounted. The drive end of the lifting cylinder 52 is connected downward to a mounting plate 53. A rolling drive structure 4 and an injector 3 are mounted on the mounting plate 53. A guide rod and guide sleeve assembly 54 is provided between the frame 51 and the mounting plate 53. The lifting cylinder, as an actuator, provides power for the overall lifting and lowering of the injector and the rolling drive structure, ensuring that the synchronous belt can contact the rotor shaft and that the injector nozzle is aligned with the rod of the rotor shaft. Furthermore, the mounting plate rigidly connects the injector and the rolling drive structure into a whole, ensuring that they maintain their relative position and move synchronously during the lifting and lowering process.

[0036] See Figure 1 As shown, the rolling drive structure 4 also includes a tensioning pulley 44 disposed above a pair of synchronous pulleys 42, with the upper surface of the synchronous belt 43 passing over the tensioning pulley 44. The tensioning pulley is used to adjust and maintain the tension of the synchronous belt, maintaining the tension of the synchronous belt. Sufficient tension ensures that there is no slippage between the synchronous belt and the synchronous pulleys, and that power is effectively transmitted. At the same time, it ensures that the lower surface of the synchronous belt has sufficient friction with the rotor shaft, reliably driving the rotor shaft to rotate.

[0037] In addition, such as Figure 4 As shown, the tip of the nozzle 31 can be designed to be flat and tilted, meaning that from a side view, the tip of the nozzle intersects the rod at a certain angle in space. This creates a slightly tilted fan-shaped spray pattern, allowing the sprayed oil mist to be directed towards the surface of the rod, covering a wider spray area and helping to improve the coverage efficiency of a single spray and enhance uniformity.

[0038] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
