Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing, specifically a lubricating oil feeding device for mechanical manufacturing. Background Technology

[0002] In the field of machinery manufacturing, lubricating oil is a key consumable that ensures the normal operation of various machine tools and equipment, and reduces wear and frictional heat of parts. Traditional and common methods of lubricating oil filling mostly rely on manual operation, where operators hold an oil can or oil gun and apply it to the equipment's oil filling hole. This method is not only inefficient and difficult to precisely control the amount added, easily leading to waste or insufficient lubrication, but also presents problems such as inconvenience, high labor intensity, and safety hazards when dealing with large equipment or complex machinery with multiple, high-level, or hidden lubrication points.

[0003] To improve the automation level of lubrication operations, some centralized lubrication systems or automatic feeding devices have emerged in the existing technology. These devices typically use oil pumps to pump lubricating oil from the oil reservoir and deliver it to various lubrication points through pipelines. However, these traditional automatic feeding devices still have significant limitations: First, their oil outlets or distributors are usually fixed, unable to flexibly adjust their angles, and difficult to adapt to oil inlets of different heights and directions, resulting in poor versatility; Second, when multiple circumferentially distributed lubrication points (such as large bearing housings, slewing bearings, etc.) need to be lubricated simultaneously, multiple independent rigid pipelines are often required, which are cumbersome to install and occupy space. Furthermore, once the equipment layout changes, the pipeline system is difficult to adjust accordingly, lacking flexibility.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a lubricating oil feeding device for mechanical manufacturing. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a lubricating oil feeding device for mechanical manufacturing.

[0006] A lubricating oil feeding device for mechanical manufacturing includes an oil storage tank and a bending plate disposed at the bottom of one side of the oil storage tank. A pump body is mounted on the bending plate. The water inlet of the pump body is connected to the oil storage tank, and the water outlet of the pump body is connected to a bent pipe. The bottom end of the bent pipe is vertically rotatably connected to an oil delivery pipe. A rotating component is disposed in the middle of the oil delivery pipe, and an oil distribution box is connected to the bottom end of the oil delivery pipe. Multiple oil distribution pipes are circumferentially and equidistantly connected to the outer side of the oil distribution box. The ends of the multiple oil distribution pipes are all connected to an oil injection pipe with a vertical structure. A corrugated section is disposed in the middle of the multiple oil distribution pipes. A connecting plate is disposed on the outer wall of the ends of the multiple oil distribution pipes. An adjustment mechanism is disposed at the bottom of the oil distribution box for controlling the movement of the multiple connecting plates to drive the expansion and contraction of the corrugated section.

[0007] Preferably, the rotating assembly includes a motor mounted on the side of the vertical section of the bending plate, the output end of the motor passing through the bending plate and connected to a main bevel gear, a driven bevel gear meshing on one side of the main bevel gear, and the driven bevel gear being installed in the middle of the oil pipeline.

[0008] Preferably, guide telescopic rods are connected between the two ends of the side of the connecting plate and the outer wall of the oil separator.

[0009] Preferably, the adjusting mechanism includes a rotating shaft rotatably disposed at the bottom of the oil separator box, a turntable connected to the bottom end of the rotating shaft, and multiple sets of connecting rods rotatably disposed at eccentric points on the lower end face of the turntable, with one end of each set of connecting rods rotatably connected to the bottom of multiple sets of connecting plates.

[0010] Preferably, the adjustment mechanism further includes two sets of ear plates disposed at the bottom of the oil separator box on one side of the rotating shaft, a worm gear rotatably disposed between the two sets of ear plates, one end of the worm gear passing through the corresponding ear plate and connected to a handwheel, and a worm wheel meshing in the middle of one side of the worm gear, the worm wheel being installed in the middle of the rotating shaft.

[0011] Preferably, the rotating shaft, the oil distribution box, and the oil delivery pipe are all located on the same central axis.

[0012] Preferably, the top of the oil tank is provided with an oil inlet pipe, and a viewing glass is embedded on the side of the oil tank away from the bending plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model can synchronously deliver lubricating oil in the oil storage tank to multiple circumferentially distributed lubrication points through the cooperation of the pump body, oil delivery pipe, oil distribution box and oil distribution pipe. In addition, by setting a rotating component, the oil distribution box, oil distribution pipe and oil injection pipe can be driven to rotate, which improves the efficiency and uniformity of lubrication operation and solves the problem of fixed oil outlet of traditional equipment and difficulty in adapting to complex lubrication point positions.

[0015] 2. This utility model features an adjustment mechanism that uses a handwheel to rotate a worm gear, which in turn drives a rotating shaft and a turntable to rotate. This, combined with a connecting rod pushing and pulling a connecting plate, causes the corrugated section of the oil distribution pipe to extend and retract, enabling synchronous adjustment of the radial spacing of multiple sets of oil injection pipes. This eliminates the need to replace or adjust rigid piping when lubricating large bearing seats and slewing bearings of different specifications. Multiple sets of oil injection pipes can precisely adapt to circumferentially distributed lubrication points of different diameters, simplifying the equipment installation and commissioning process.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides a lubricating oil feeding device for mechanical manufacturing, including an oil storage tank 1 and a bent plate 2 set at the bottom of one side of the oil storage tank 1. A pump body 3 is installed on the bent plate 2. The water inlet end of the pump body 3 is connected to the oil storage tank 1, and the water outlet end of the pump body 3 is connected to a bent pipe 4. The bottom end of the bent pipe 4 is vertically rotatably connected to an oil delivery pipe 5. A rotating component 6 is set in the middle of the oil delivery pipe 5. The bottom end of the oil delivery pipe 5 is connected to an oil distribution box 7. The outer side of the oil distribution box 7 is circumferentially connected to multiple oil component pipes 8. The ends of the multiple oil component pipes 8 are all connected to oil injection pipes 9 with a vertical structure. A corrugated section 10 is set in the middle of the multiple oil component pipes 8. A connecting plate 11 is set on the outer wall of the ends of the multiple oil component pipes 8. An adjustment mechanism 12 is set at the bottom of the oil distribution box 7 for controlling the movement of the multiple connecting plates 11 to drive the corrugated section 10 to extend and retract.

[0026] When lubrication is required, the lubricating oil in the oil storage tank 1 is drawn into the bent pipe 4 by the pump body 3 and then transported to the oil distribution box 7 through the oil delivery pipe 5. The oil in the oil distribution box 7 is then transported to the oil injection pipe 9 through the oil distribution pipe 8, thereby realizing multi-point synchronous lubrication of mechanical manufacturing parts.

[0027] It should be noted that the vertical rotational connection structure between the bottom end of the bent pipe 4 and the oil pipe 5 ensures that the internal lubricating oil does not leak during the rotation of the oil pipe 5. This principle is consistent with the sealing principle of common rotating fluid transmission devices such as rotating sprinklers for garden irrigation and rotating sprinkler heads for cleaning equipment. Both are mature existing technologies in this field and will not be elaborated further here.

[0028] refer to Figure 1 , Figure 3 and Figure 4 The rotating assembly 6 includes a motor 601 mounted on the side of the vertical section of the bending plate 2. The output end of the motor 601 passes through the bending plate 2 and is connected to a main bevel gear 602. A driven bevel gear 603 is meshed on one side of the main bevel gear 602. The driven bevel gear 603 is mounted in the middle of the oil pipe 5.

[0029] In the multi-point lubrication process, the motor 601 drives the main bevel gear 602 to rotate. The main bevel gear 602 meshes with the driven bevel gear 603. During the rotation of the driven bevel gear 603, the oil distribution box 7 is driven to rotate through the oil supply pipe 5. During the rotation of the oil distribution box 7, multiple oil injection pipes 9 move in a circular motion along the circumferential lubrication path, which improves the uniformity and effectiveness of lubrication along the lubrication path.

[0030] refer to Figure 3 Guide telescopic rods 13 are connected between the two ends of the side of the connecting plate 11 and the outer wall of the oil separator 7.

[0031] The guide telescopic rod 13 guides and limits the movement trajectory of the connecting plate 11, so that the corrugated section 10 can horizontally extend and retract as the connecting plate 11 moves.

[0032] refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The adjusting mechanism 12 includes a rotating shaft 1201 rotatably disposed at the bottom of the oil separator 7. The bottom end of the rotating shaft 1201 is connected to a turntable 1202. Multiple sets of connecting rods 1203 are rotatably disposed at the eccentric part of the lower end face of the turntable 1202 in a circular manner. One end of the multiple sets of connecting rods 1203 is rotatably connected to the bottom of multiple sets of connecting plates 11 respectively.

[0033] refer to Figure 3 and Figure 5 The adjustment mechanism 12 also includes two sets of ear plates 1204 located at the bottom of the oil separator 7 on one side of the rotating shaft 1201. A worm gear 1205 is rotatably arranged between the two sets of ear plates 1204. One end of the worm gear 1205 passes through the corresponding ear plate 1204 and is connected to a handwheel 1206. A worm wheel 1207 is meshed in the middle of one side of the worm gear 1205. The worm wheel 1207 is installed in the middle of the rotating shaft 1201.

[0034] Specifically, by rotating the worm gear 1205 through the handwheel 1206, the worm gear 1205 meshes with the worm wheel 1207, driving the rotating shaft 1201 to rotate. During the rotation of the rotating shaft 1201, the turntable 1202 is driven to rotate. By utilizing the pushing and pulling action of the connecting rod 1203 at the eccentric part of the turntable 1202, the synchronous movement of multiple sets of connecting plates 11 is achieved, thereby controlling the extension and retraction of the corrugated section 10 of the oil distribution pipe 8, thus precisely adjusting the radial spacing of the oil injection pipe 9 to adapt to the oil injection needs of circumferentially distributed lubrication points of different diameters.

[0035] refer to Figure 5 The rotating shaft 1201, the oil distribution box 7, and the oil delivery pipe 5 are all located on the same central axis.

[0036] Among these features, being located on the same central axis avoids eccentric loads and also prevents positional deviations in the oil injection pipe 9 during adjustment, thus improving the accuracy of oil injection.

[0037] refer to Figure 1 and Figure 2 An oil inlet pipe 101 is provided on the top of the oil tank 1, and a viewing glass 102 is embedded on the side of the oil tank 1 away from the bending plate 2.

[0038] The oil inlet pipe 101 facilitates the addition of lubricating oil, ensuring that the equipment can continuously obtain a sufficient supply of lubricating medium to maintain normal operation. The embedded viewing glass 102 provides operators with a way to intuitively observe the remaining amount of lubricating oil in the oil tank 1. The operator can check the lubricating oil level at any time without opening the oil tank 1. When the lubricating oil level is insufficient, the operator can promptly detect and replenish it.

[0039] Working Principle: During lubrication, pump body 3 is first started. Pump body 3 draws lubricating oil from oil tank 1 through the inlet and delivers it to bend pipe 4 through outlet. Bend pipe 4 guides oil delivery pipe 5, and the lubricating oil flows through oil delivery pipe 5 into oil distribution box 7. Oil distribution box 7 evenly distributes the lubricating oil to multiple interconnected, circumferentially spaced oil distribution pipes 8, and then injects it into each lubrication point through oil injection pipe 9 at the end of oil distribution pipe 8, completing the overall lubrication operation. During lubrication, motor 601 drives main bevel gear 602 to rotate. Main bevel gear 602, through meshing with driven bevel gear 603, drives oil delivery pipe 5, oil distribution box 7, and oil injection pipe 9 to rotate vertically, improving the uniformity and effectiveness of lubrication along the lubrication path. When adjustment of oil injection is needed... When adjusting the radial spacing of the pipes 9, the handwheel 1206 is turned, which drives the worm gear 1205 to rotate. The worm gear 1205 meshes with the worm wheel 1207, driving the rotating shaft 1201 and the turntable 1202 at the bottom of the rotating shaft 1201 to rotate synchronously. Multiple sets of connecting rods 1203 connected to the eccentric part of the lower end face of the turntable 1202 generate a pushing and pulling action as the turntable 1202 rotates, which respectively drives the connecting plate 11 connected to it to move. The connecting plate 11 moves smoothly under the limiting guidance of the side guide telescopic rod 13, causing the corrugated section 10 in the middle of the oil distribution pipe 8 to extend and retract, thereby adjusting the radial spacing of the multiple sets of oil injection pipes 9, so that each set of oil injection pipes 9 is precisely aligned with the corresponding lubrication point, which can lubricate large bearing seats and slewing bearings of different specifications.
