Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing equipment technology, and in particular to an oiling device for a stator housing. Background Technology

[0002] The bottom of the stator housing is equipped with a baffle to prevent friction between the motor shaft and the bottom of the housing. During the motor production and assembly process, the baffle at the bottom of the stator housing needs to be lubricated to reduce wear between the motor shaft and the baffle.

[0003] Currently, this oiling process mainly relies on manual operation: workers use wooden sticks or cotton swabs to apply lubricating oil to the bottom baffle of the stator housing. However, manual operation is labor-intensive and inefficient.

[0004] Although automated dispensing and coating equipment exists in the existing technology, these devices are mainly single-station and have limited efficiency. Some existing equipment also uses dual-station equipment; however, the two stations are usually independent of each other, and the lifting and moving devices and product fixing devices are mostly arranged vertically, resulting in a relatively complex overall structure and higher manufacturing costs. Summary of the Invention

[0005] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide an oiling device for stator housing, which can effectively improve the oiling efficiency of stator housing. At the same time, its structure is simple and reasonable and its manufacturing cost is low.

[0006] This utility model is achieved through the following technical solution: an oiling device for a stator housing, comprising a base, a product fixing seat, a lifting drive assembly, and at least two dispensing assemblies for connecting to an oil supply pipeline; the product fixing seat and the lifting drive assembly are both disposed on the base, the product fixing seat is provided with at least two receiving slots for placing the stator housing, and the dispensing assemblies are correspondingly disposed above the receiving slots and connected to the output end of the lifting drive assembly.

[0007] Compared with existing technologies, the oiling device provided by this utility model has at least two receiving slots on the product fixing base. Each dispensing component is correspondingly positioned above a receiving slot and connected to the output end of a lifting drive component. The lifting drive component drives multiple dispensing components to descend, simultaneously applying oil to the stator housing within multiple receiving slots, thereby effectively improving the oiling efficiency of the stator housing. The lifting drive component, located on the base, enables the lifting of multiple dispensing components, resulting in a simple and reasonable structure with low manufacturing costs.

[0008] Furthermore, the system also includes valves, through which each dispensing component is connected to the oil supply line. Each valve includes a first trigger portion located at the output end of the lifting drive component, and a second trigger portion located on the base. When the lifting drive component lowers the dispensing component to the oiling position, the first trigger portion contacts the second trigger portion, and the valve connects the dispensing component to the oil supply line. By controlling the oil supply to the dispensing component through the valves, and by ensuring the contact between the first and second trigger portions, the system ensures that the dispensing component descends to the designated position before applying oil to the stator housing, thus ensuring the accuracy of the oiling process.

[0009] Furthermore, it also includes a connecting bracket disposed at the output end of the lifting drive assembly, and both the dispensing assembly and the first trigger part are disposed on the connecting bracket. The connecting bracket provides support for the first trigger part and each dispensing assembly.

[0010] Furthermore, the dispensing assembly comprises two sets; the connecting bracket is an inverted U-shaped bracket, which includes a support portion disposed at the output end of the lifting drive assembly, and two connecting portions respectively disposed on both sides of the support portion; the two sets of dispensing assemblies are respectively disposed on the outer sides of the two connecting portions, and the first trigger portion is disposed on the support portion. The inverted U-shaped bracket design improves the structural stability of the connecting bracket, thereby enhancing the smoothness of the dispensing assembly's lifting and lowering.

[0011] Furthermore, the product mounting base is provided with a limiting part to prevent the stator housing from disengaging from the receiving groove. This limiting part prevents the product from shifting due to vibration of the stator housing during operation.

[0012] Furthermore, the limiting part is a magnet, and the receiving groove is provided with a groove that matches the magnet, and the magnet is engaged in the groove. The stator housing is attracted and fixed by the magnet.

[0013] Furthermore, the product mounting base is provided with clearance grooves, which are located on both sides of the receiving groove and are connected to the receiving groove. The clearance grooves facilitate the placement and removal of the stator housing.

[0014] Furthermore, the base includes a base plate and two support plates; the lifting drive assembly includes a lifting drive cylinder, which is vertically disposed between the support plates, and its output end is connected to the support portion. The vertically disposed lifting drive cylinder between the support plates helps reduce the space occupied by the lifting drive assembly and lowers the manufacturing cost of the oiling device.

[0015] Furthermore, the coating device also includes a guide assembly, which comprises a guide rail and a slider. The guide rail is vertically positioned on the support plate, and the slider is located inside the connecting portion and slides in cooperation with the guide rail. The design of the guide assembly improves the smoothness of the dispensing assembly's lifting and lowering.

[0016] Furthermore, the valve is a mechanical valve, located at the output end of the lifting drive cylinder. The first trigger is the switch of the mechanical valve, and the second trigger is the top surface of the support plate. When the lifting drive assembly drives the dispensing assembly to descend to the oiling position, the top surface presses against the switch. The valve is a mechanical valve, and the accurate oil supply to the dispensing assembly is ensured through physical contact.

[0017] Furthermore, the dispensing assembly includes a metering dispensing valve disposed at the connecting portion and a dispensing head disposed at the output end of the metering dispensing valve; the metering dispensing valve is provided with a knob for adjusting the oil flow rate. The metering dispensing valve ensures that a precise amount of oil is applied to the stator housing, avoiding insufficient or excessive grease application. The knob adjusts the oil flow rate.

[0018] Furthermore, the oiling device also includes a foot switch for controlling the connection and disconnection of the lifting drive cylinder and the air supply line, wherein the lifting drive cylinder is connected to the air supply line via the foot switch. The foot switch controls the lifting and lowering of the dispensing assembly.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] like Figures 1 to 3 As shown, this embodiment provides an oiling device for stator housings, including a base 10, a product fixing seat 20, a lifting drive assembly, and at least two dispensing assemblies 60 for connection to oil supply lines. The product fixing seat 20 and the lifting drive assembly are both disposed on the base 10. The product fixing seat 20 has at least two receiving slots 80 for placing the stator housing. The dispensing assemblies 60 are correspondingly disposed above each of the receiving slots 80 and connected to the output end of the lifting drive assembly. By providing at least two receiving slots 80 on the product fixing seat 20 and correspondingly dispensing assemblies 60 above each receiving slot 80 and connected to the output end of the lifting drive assembly, multiple dispensing assemblies 60 are driven to descend by the lifting drive assembly, simultaneously applying oil to the stator housings within the multiple receiving slots 80, thereby effectively improving the oiling efficiency of the stator housing. The lifting drive assembly on the base 10 enables the lifting of multiple dispensing assemblies 60, resulting in a simple and reasonable structure with low manufacturing costs.

[0026] In this embodiment, a valve 70 is also included. All dispensing assemblies 60 are connected to the oil supply line via the valve 70. The valve 70 includes a first trigger part 71 located at the output end of the lifting drive assembly, and a second trigger part 121 is provided on the base 10. When the lifting drive assembly drives the dispensing assembly 60 to descend to the oiling position, the first trigger part 71 contacts the second trigger part 121, and the valve 70 connects the dispensing assembly 60 to the oil supply line. The valve 70 controls the oil supply to the dispensing assembly 60, and the contact between the first trigger part 71 and the second trigger part 121 ensures that the dispensing assembly 60 descends to the set position before oiling the stator housing, ensuring the accuracy of the oiling process.

[0027] In this embodiment, a connecting bracket 40 is also provided at the output end of the lifting drive component, and the dispensing component 60 and the first trigger part 71 are both provided on the connecting bracket 40. The connecting bracket 40 provides support for the first trigger part 71 and each dispensing component 60.

[0028] In this embodiment, there are two sets of dispensing assemblies 60, and the connecting bracket 40 is an inverted U-shaped bracket, which includes a support portion 41 disposed at the output end of the lifting drive assembly, and two connecting portions 42 respectively disposed on both sides of the support portion 41; the two sets of dispensing assemblies 60 are respectively disposed on the outer sides of the two connecting portions 41, and the first trigger portion 71 is disposed on the support portion 41. The two sets of dispensing assemblies 60 simultaneously perform oiling operations on the two stator housings. The inverted U-shaped design provides support for the two sets of dispensing assemblies 60, while improving the structural stability of the connecting bracket 40, thereby improving the smoothness of the lifting and lowering of the dispensing assemblies 60. Of course, in other alternative embodiments, the dispensing assembly 60 is not limited to two sets, but can be multiple sets (such as three, four, or more). Multiple sets of dispensing assemblies 60 are arranged around the output end of the lifting drive assembly on the connecting bracket 40. For example, the connecting bracket 40 includes a support portion 41 and several connecting portions 42, with the connecting portions 42 surrounding the support portion 41 and disposed at its edge. The dispensing assemblies 60 are correspondingly disposed on each of the connecting portions 42. The first trigger portion 71 is disposed on the support portion 41 and located between any two sets of dispensing assemblies 60, or at the bottom of the support portion 41. Of course, in other alternative embodiments, the connecting bracket 40 is not limited to the structural form of the support portion 41 and the connecting portions 42; the connecting bracket 40 can be a frame or a straight plate structure. In this embodiment, the support portion 41 and the two connecting portions 42 are separate designs and can be connected by screws, clips, welding, etc. Of course, in other alternative embodiments, the support portion 41 and the two connecting portions 42 can be an integrated design.

[0029] In this embodiment, the base 10 includes a base plate 11 and two support plates 12 vertically disposed on the base 11. The lifting drive assembly includes a lifting drive cylinder 30, which is vertically disposed between the support plates 12, and its output end is connected to the support portion 41. The vertically disposed lifting drive cylinder 30 between the support plates 12 helps reduce the space occupied by the lifting drive assembly and lowers the manufacturing cost of the oiling device. In this embodiment, the two support plates 12 are respectively close to both sides of the lifting drive cylinder 30 and are fixedly connected to the lifting drive cylinder 30 by fasteners. This arrangement helps reduce the vibration of the lifting drive cylinder 30 during extension and retraction, improving the stability of the dispensing assembly 60's lifting. Preferably, the lifting drive cylinder 30 is a dual-axis cylinder to improve the stability and smoothness of the dispensing assembly 60's lifting. Of course, in other alternative embodiments, the lifting drive cylinder 30 can also be a single-axis cylinder. Of course, in other alternative embodiments, the lifting drive assembly is not limited to the structure of a cylinder. For example, the lifting drive assembly may include a drive motor and a lead screw slide, with the drive motor vertically mounted on the base plate 11, and the lead screw in the lead screw slide located at the output end of the drive motor. The connecting bracket 40 is connected to the slide, which can also realize the lifting of the connecting bracket 40. Alternatively, the lifting drive assembly may include an electric push rod, with the connecting bracket 40 located at the output end of the electric push rod.

[0030] In this embodiment, the product fixing base 20 includes a first product fixing base 21 and a second product fixing base 22, which are disposed back-to-back on the base plate 11, and both support plates 12 are located between the first product fixing base 21 and the second product fixing base 22. Both the first product fixing base 21 and the second product fixing base 22 are provided with the receiving groove 80. The design of the first product fixing base 21 and the second product fixing base 22 avoids mutual interference when placing the stator housing. Of course, in other alternative embodiments, the product fixing base 20 can be an integrally formed base body, which has a clearance groove for installing the support plate 12 and the lifting drive cylinder 30. In this embodiment, the receiving groove 80 has an opening on the side away from the lifting drive cylinder 30, that is, the cross-sectional shape of the receiving groove 80 is C-shaped, which matches part of the outer peripheral contour of the stator housing (i.e., matches part of the cross-sectional shape of the stator housing), thereby facilitating the positioning and placement of the stator housing. Of course, in other alternative embodiments, the cross-sectional shape of the receiving groove 80 may be matched with the cross-sectional shape of the stator housing.

[0031] In this embodiment, both the first product fixing seat 21 and the second product fixing seat 22 are provided with limiting parts 82 for preventing the stator housing from falling out of the receiving groove 80. The limiting parts 82 prevent the stator housing from shifting due to vibration during operation.

[0032] Specifically, the limiting part 82 is a magnet, and the receiving groove 80 has a groove matching the magnet, with the magnet being engaged within the groove. The stator housing is attracted and fixed by the magnet. The magnet can be a magnet or an electromagnet, etc. Of course, in other alternative embodiments, the limiting part 82 is not limited to a magnet; it can be a cover for abutting against the stator housing. One end of the cover is hinged to one side of the opening, and the other end of the cover engages with the other side of the opening. The cover limits the position of the stator housing.

[0033] In this embodiment, the product mounting base 20 is provided with clearance grooves 81, which are located on both sides of the receiving groove 80 and are connected to the receiving groove 80. The clearance grooves 81 facilitate the placement and removal of the stator housing.

[0034] In this embodiment, the support plate 12 is parallel to the connecting portion 42. The oiling device further includes a guide assembly 50, which includes a guide rail 51 and a slider 52. The guide rail 51 is vertically disposed on the support plate 12, and the slider 52 is located inside the connecting portion 42 and slides in cooperation with the guide rail 51. The design of the guide assembly 50 improves the smoothness of the lifting and lowering of the dispensing assembly 60. Of course, in other alternative embodiments, the guide assembly 60 may include a boss extending vertically, which is disposed on the support plate 12. The connecting portion 42 has a groove matching the boss on its inner side, and one end of the boss is disposed in the groove. The cooperation between the groove and the boss also achieves the guiding of the lifting and lowering of the connecting portion 42.

[0035] In this embodiment, the valve 70 is a mechanical valve, which is disposed on the support portion 41. The first trigger portion is the switch of the mechanical valve, and the second trigger portion is the top surface of the support plate 12. When the lifting drive assembly drives the dispensing assembly 60 to descend to the oiling position, the top surface presses against the switch. The valve is a mechanical valve, and the valve is opened by physical contact, ensuring the accuracy of oil supply to the dispensing assembly 60. Of course, in other alternative embodiments, the valve can be a solenoid valve, the second trigger portion 121 is a sensing block disposed on the support plate 12, and the first trigger portion 71 is an infrared sensor disposed on the support portion 41. When the lifting drive assembly drives the dispensing assembly 60 to descend to the oiling position, the sensing block enters the sensing range of the infrared sensor and triggers the infrared sensor, thereby energizing and opening the solenoid valve.

[0036] In this embodiment, the dispensing assembly 60 includes a metering dispensing valve 61 disposed on the connecting portion 42, and a dispensing head 62 disposed on the output end of the metering dispensing valve 61; the metering dispensing valve 61 is provided with a knob 611 for adjusting the oil flow rate. The metering dispensing valve 61 ensures that a precise amount of oil is applied to the stator housing, avoiding insufficient or excessive oil application. The knob 611 is used to adjust the oil flow rate. Of course, in other alternative embodiments, the dispensing valve is not limited to the metering dispensing valve 61 and can be other dispensing valves. In this embodiment, the dispensing head 62 is needle-shaped, and its output end extends into the stator housing to apply oil to the baffle at the bottom of the stator housing.

[0037] In this embodiment, the oiling device further includes a foot switch (not shown) for controlling the connection and disconnection between the lifting drive cylinder 30 and the air supply line. The lifting drive cylinder is connected to the air supply line via the foot switch. The foot switch controls the lifting and lowering of the dispensing assembly 60. Alternatively, in other alternative embodiments, the oiling device may include a controller and a button, both electrically connected to the controller. Thus, after the stator housing is placed, it can be started via the button. Upon receiving the start signal from the button, the controller controls the lifting drive assembly to lower the dispensing assembly 60.

[0038] In some alternative embodiments, the oiling device further includes an oil supply unit connected to the valve 70 via an oil supply line. In this embodiment, the oil supply unit is a double-column grease gun. Of course, in other alternative embodiments, a hydraulic pump is used. In some alternative embodiments, the oiling device further includes an air supply pump connected to the foot switch via an air supply line, and the foot switch is connected to the lifting drive cylinder 30.

[0039] Compared with existing technologies, the oiling device provided by this utility model has at least two receiving slots on the product fixing base. Each dispensing component is correspondingly positioned above a receiving slot and connected to the output end of a lifting drive component. The lifting drive component drives multiple dispensing components to descend, simultaneously applying oil to the stator housing within multiple receiving slots, thereby effectively improving the oiling efficiency of the stator housing. The lifting drive component, located on the base, enables the lifting of multiple dispensing components, resulting in a simple and reasonable structure with low manufacturing costs.
