Description

Technical Field

[0001] This utility model relates to the field of multi-directional worm shaft technology, and in particular to a multi-directional worm shaft that is easy to lubricate and maintain. Background Technology

[0002] A worm shaft is a type of shaft component with a special geometric structure and transmission function. It can realize the driving of multiple driven worm gears by one driving shaft, and complete the multi-directional motion transmission and power distribution. Its outer surface is machined with a helical tooth structure, similar to a screw, but the tooth profile is specially designed to adapt to the meshing requirements of multiple worm gears in different directions. By rotating the worm shaft, rotational motion can be converted into rotational or linear motion of multiple worm gears, realizing the conversion and transmission of motion and meeting the motion control requirements of mechanical systems in multiple dimensions.

[0003] However, existing lubrication methods for multi-directional worm shafts have many drawbacks. The traditional method of manually applying lubricating oil periodically requires disassembling the housing containing the multi-directional worm shaft and then applying the oil manually. This not only consumes a lot of manpower and time, but also involves directly pouring the corresponding amount of lubricating oil onto the surface of the multi-directional worm shaft. When there is too much oil, most of the lubricating oil will flow out onto the surface of the multi-directional worm shaft, resulting in waste. Therefore, a multi-directional worm shaft that is easy to lubricate and maintain is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-directional worm shaft that is easy to lubricate and maintain, aiming to improve the problem that manual lubrication and maintenance of multi-directional worm shafts is relatively troublesome in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-directional worm shaft that is easy to lubricate and maintain, comprising a housing, wherein the inner wall of the housing is rotatably connected to the multi-directional worm shaft, and an oiling mechanism is provided on the upper surface of the housing;

[0006] The oiling mechanism includes an oil tank fixedly connected to the upper surface of the housing, a movable plate slidably connected to the top inner wall of the housing, a support column fixedly connected to the bottom of the oil tank via a valve, a dripping device provided on the top inner wall of the support column, a movable column slidably connected to the inner wall of the support column, a movable plate elastically connected to the top inner wall of the housing via a return spring, a sponge pad fixedly connected to the bottom inner wall of the movable plate, and a positioning component provided on the upper surface of the housing.

[0007] As a further description of the above technical solution:

[0008] The dripping component includes a sleeve fixedly connected to the inner wall of the top of the support column, and the cross-section of the sleeve is configured as a frustum shape.

[0009] As a further description of the above technical solution:

[0010] The bottom of the movable column is fixedly connected to the upper surface of the movable plate, and the cross-section of the movable column is T-shaped.

[0011] As a further description of the above technical solution:

[0012] The bottom end of the movable plate is fixedly connected to the upper surface of the movable plate, and the movable plate is configured as an inverted L-shape.

[0013] As a further description of the above technical solution:

[0014] The bottom of the sponge pad is in contact with the threaded surface of the multi-directional worm shaft.

[0015] As a further description of the above technical solution:

[0016] Holes are provided at the center of the support column, sponge pad, movable column and its movable plate.

[0017] As a further description of the above technical solution:

[0018] The positioning component includes a fixing block fixedly connected to the upper surface of the housing. The inner wall of the fixing block is elastically connected to a limiting post via a connecting spring. The outer wall of the limiting post penetrates and is slidably connected to the inner wall of the fixing block. The positioning block is fixedly connected to the side of the limiting post away from the connecting spring.

[0019] As a further description of the above technical solution:

[0020] The bottom of the positioning block is provided with a horizontal groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the mutual cooperation between the multi-directional worm shaft, housing and its oiling mechanism, when the multi-directional worm shaft needs maintenance, the outward movement of the limiting post releases the limitation on the moving plate, and then the valve is opened to allow lubricating oil to enter the sponge pad. The moving plate can determine whether the sponge pad is in contact with the multi-directional worm shaft, thus facilitating the lubrication and maintenance of the multi-directional worm shaft. The operation is relatively simple.

[0023] 2. In this utility model, the positioning block can fix the moving plate by the cooperation between the positioning components and other structures, thereby avoiding the operation of the sponge pad possibly detaching from the worm shaft surface and causing lubrication failure.

[0031] 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.

[0032] Reference Figures 1-2 The present invention provides an embodiment of a multi-directional worm shaft that is easy to lubricate and maintain, comprising a housing 1, wherein a multi-directional worm shaft 2 is rotatably connected through the inner wall of the housing 1, and a worm wheel is provided inside the housing 1 so as to cooperate with the multi-directional worm shaft 2. This is prior art and will not be explained in detail here. An oiling mechanism 3 is provided on the upper surface of the housing 1; the oiling mechanism 3 enables the multi-directional worm shaft 2 to be lubricated and maintained.

[0033] Reference Figures 2-4The oiling mechanism 3 includes an oil tank 301 fixedly connected to the upper surface of the housing 1. A movable plate 305 is slidably connected to the inner top wall of the housing 1. Two sets of movable plates 305 are provided. A support column 308 is fixedly connected to the bottom of the oil tank 301 via a valve 302. The valve 302 allows the lubricating oil inside the oil tank 301 to be discharged downwards into the support column 308. A dripping element is provided on the inner top wall of the support column 308, which guides the lubricating oil outwards. A sliding connection is also provided on the inner wall of the support column 308. The movable column 307 can move vertically. The top inner wall of the housing 1 is elastically connected to the movable plate 304 through the return spring 303. The elasticity of the return spring 303 enables the movable plate 304 to have a reset function. The bottom inner wall of the movable plate 304 is fixedly connected to the sponge pad 309. The downwardly discharged lubricating oil will enter the interior of the sponge pad 309 to facilitate subsequent use and maintenance. The upper surface of the housing 1 is provided with a positioning component 4, which can fix the movable plate 305.

[0034] Reference Figures 2-4 The dripping component includes a sleeve 306 fixedly connected to the inner top wall of the support column 308. The sleeve 306 has a frustum-shaped cross-section, which allows the lubricating oil to concentrate towards the center as it moves downwards, thus accurately draining into the interior of the movable column 307. The bottom of the movable column 307 is fixedly connected to the upper surface of the movable plate 304, and the two move along the same trajectory. When the lubricating oil inside the sponge pad 309 reaches a certain level, the combined weight of the movable column 307, the movable plate 304, the sponge pad 309, and its internal lubricating oil exceeds the weight of the return spring 303, allowing the sponge pad 309 to move downwards. The movable column 307 has a T-shaped cross-section to prevent it from falling off during movement. The bottom end of the movable plate 305 is fixedly connected to the upper surface of the movable plate 304, and the two move in tandem. The movement trajectory is consistent. The movable plate 305 is designed in an inverted L-shape. This inverted L-shape ensures that when the movable plate 305 moves downwards, its inner top surface contacts the top of the housing 1, indicating to the operator that the sponge pad 309 is ready for lubrication. The bottom of the sponge pad 309 contacts the threaded surface of the multi-directional worm shaft 2. This contact arrangement ensures that the multi-directional worm shaft 2 rotates and presses against the sponge pad 309, allowing lubricating oil to flow onto the surface of the multi-directional worm shaft 2. The rotation of the multi-directional worm shaft 2 then transfers the surface lubricating oil to the worm wheel for lubrication maintenance. Holes are provided at the center of the support column 308, sponge pad 309, movable column 307, and movable plate 304. These holes allow lubricating oil to flow downwards through the oil tank 301 and into the interior of the sponge pad 309. Figure 3 As shown, at this time, the positioning block 402 supports the top inner side of the moving plate 305 to prevent the moving plate 305 from moving downward.

[0035] Reference Figure 2 , Figure 3 and Figure 5 The positioning component 4 includes a fixing block 401 fixedly connected to the upper surface of the housing 1. The inner wall of the fixing block 401 is elastically connected to a limiting post 404 via a connecting spring 403. The elasticity of the connecting spring 403 enables the limiting post 404 to have the functions of resetting and limiting. The outer wall of the limiting post 404 is slidably connected to the inner wall of the fixing block 401. The through-hole setting facilitates manual outward movement of the limiting post 404, thereby releasing the limiting post 404 from its limiting position. A positioning block 402 is fixedly connected to the side of the limiting post 404 away from the connecting spring 403. A transverse groove is provided at the bottom of the positioning block 402. The transverse groove allows the moving plate 305 to move downward as a whole. When its inner side contacts the top of the housing 1 (at this time, the sponge pad 309 contacts the threaded surface of the multi-directional worm shaft 2), the inner side of the transverse groove contacts the top of the moving plate 305, thereby fixing the moving plate 305 and preventing the sponge pad 309 from moving upward when the multi-directional worm shaft 2 rotates.

[0036] Working principle: When lubrication maintenance is required for the multi-directional worm shaft 2, the valve 302 at the bottom of the oil tank 301 is opened. The lubricating oil flows downward through the valve 302, pulling the limiting column 404 outward. This releases the support of the positioning block 402 on the moving plate 305. After being guided and concentrated by the top sleeve 306 (frustum-shaped design), the lubricating oil enters the interior of the moving column 307, and then flows into the sponge pad 309 through the central hole of the moving column 307 and its moving plate 304. When the sponge pad 309 absorbs a certain weight of lubricating oil, the total weight of the sponge pad 309, the moving column 307, and the moving plate 304 exceeds the elastic force of the return spring 303. The moving plate 304 then drives the moving plate 305 (inverted L-shape) and the sponge pad 309. Moving downwards, the inner top of the moving plate 305 contacts the top of the housing 1. Then, the limiting post 404 is released. At this time, due to the elasticity of the connecting spring 403, the positioning block 402 is reset and contacts the top of the moving plate 305, thus preventing the moving plate 305 from moving vertically. (At this time, the bottom of the sponge pad 309 contacts the threaded surface of the multi-directional worm shaft 2). When the multi-directional worm shaft 2 rotates, it squeezes the sponge pad 309, causing lubricating oil to remain on its surface and be transmitted to the worm wheel through rotation. When the lubricating oil is consumed, the weight is reduced, and the limiting is released again through the positioning component 4. The reset spring 303 drives the moving plate 304 to reset, and the moving plate 305 disengages from the transverse groove of the positioning block 402. The oiling operation can be repeated.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
