Description

Technical Field

[0001] This application relates to the field of mechanical oiling equipment, and more specifically, to a semi-automatic gear oiling mechanism. Background Technology

[0002] In the gear manufacturing process, to ensure gear assembly accuracy, reduce wear, and extend service life, lubricating oil needs to be applied to the gear surface. Currently, there are two main methods for gear oiling on the market: The first is to manually apply lubricating oil to the gear with a brush. This method is inefficient and results in uneven application, failing to meet the needs of mass production. Furthermore, manual operation can lead to unstable oil volume control, affecting gear performance. The second method uses a metering valve in conjunction with a motor-driven gear rotation. The process involves placing the gear on a template, the motor rotating the template, and the metering valve, driven by a cylinder, moving to the gear to expel lubricating oil. While this method improves application uniformity, its structure is more complex, requiring a motor-driven square template to rotate and apply the lubricating oil. Therefore, we propose a semi-automatic gear oiling mechanism. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a semi-automatic gear oiling mechanism, which aims to improve the problems of low efficiency and unevenness of manual oiling.

[0004] This application provides a semi-automatic gear oiling mechanism, including a base, on which a lubricating oil conveying assembly for quantitatively conveying lubricating oil is installed. A gear fixture is also installed on the top of the base. The gear fixture has a conforming gear groove and a lubricating oil guiding cavity. A plurality of oil outlet holes are formed between the lubricating oil guiding cavity and the conforming gear groove. The lubricating oil conveying assembly is connected to the lubricating oil guiding cavity.

[0005] In one specific embodiment, the lubricating oil delivery assembly includes a bracket mounted on the base, a metering valve for metering lubricating oil is mounted on the bracket, an optical sensor for detecting the presence of gears is also mounted on the bracket, and a first conduit is connected to the outlet of the metering valve, the first conduit being connected to the lubricating oil guide cavity.

[0006] In one specific embodiment, the lubricating oil delivery assembly further includes an oil tank for storing lubricating oil, and a second conduit is connected to the side wall of the oil tank, the second conduit being connected to the inlet of the metering valve.

[0007] In one specific implementation, the lubricating oil guiding cavity includes a guiding hole, a first guiding groove, and a second guiding groove formed in the gear fixture. The guiding hole is connected to the second guiding groove through the first guiding groove. The first conduit is connected to the guiding hole. A plurality of oil outlet holes are all connected to the first guiding groove.

[0008] In one specific implementation, several oil outlet holes are located on several tooth surfaces of the contour gear groove, and the oil outlet holes on the several tooth surfaces are staggered and spaced at different heights.

[0009] In one specific embodiment, the gear fixture includes a base mounted on the base, an assembly seat mounted on the top of the base, a guide hole and a first guide groove both formed within the base, a second guide groove formed within the assembly seat, and a contoured gear groove formed on the assembly seat.

[0010] In one specific implementation, a first sealing ring, a second sealing ring, and a third sealing ring are installed between the mounting base and the base, and an oil drain pipe is connected to the bottom of the profiled gear groove.

[0011] In one specific implementation, a common screw passes between the base and the mounting base, and a nut is screwed onto the screw.

[0012] The beneficial effects of this application are as follows: By installing a lubricating oil delivery assembly and a gear fixture on the base, the gear fixture has a lubricating oil guiding cavity and a contoured gear groove on its top. Several oil outlet holes are opened between the contoured gear groove and the lubricating oil guiding cavity. The gear to be lubricated is placed in the contoured gear groove, and the lubricating oil is delivered to the lubricating oil guiding cavity through the lubricating oil delivery assembly.

Detailed Implementation

[0021] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0022] Please see Figure 1-6 This application provides a semi-automatic gear oiling mechanism, including a base 10, on which a lubricating oil conveying assembly 20 for quantitatively conveying lubricating oil is installed. A gear fixture 30 is also installed on the top of the base 10. The gear fixture 30 has a conforming gear groove 40, which is adapted to the shape of the gear. At the same time, there is a gap between the tooth surface of the conforming gear groove 40 and the tooth surface of the gear. A lubricating oil guiding cavity 50 is provided in the gear fixture 30. A plurality of oil outlet holes 60 are provided between the lubricating oil guiding cavity 50 and the conforming gear groove 40. The lubricating oil conveying assembly 20 is connected to the lubricating oil guiding cavity 50. The lubricating oil conveying assembly 20 conveys lubricating oil into the lubricating oil guiding cavity 50. The lubricating oil is applied to the tooth surface of the gear through the plurality of oil outlet holes 60.

[0023] See Figure 1The lubricating oil delivery assembly 20 includes a bracket 210 mounted on a base 10. A metering valve 220 for metering lubricating oil is mounted on the bracket 210. An optical sensor 230 for detecting the presence of a gear is also mounted on the bracket 210. The outlet of the metering valve 220 is connected to a first conduit 240, which is connected to a lubricating oil guide cavity 50. In a specific configuration, the gear is placed in a contoured gear groove 40. The optical sensor 230 detects the presence of the gear and feeds a signal back to the existing control module, causing the metering valve 220 to operate and deliver a metered amount of lubricating oil. Specifically, the optical sensor 230 emits light towards the gear, which is reflected by the gear and detected by the optical sensor 230. Furthermore, the lubricating oil delivery assembly 20 also includes an oil tank 250 for storing lubricating oil. A second conduit 260 is connected to the side wall of the oil tank 250 and is connected to the inlet of the metering valve 220. The metering valve 220 draws lubricating oil from the oil tank 250 through the second conduit 260.

[0024] See Figure 3 and 6 The lubricating oil guiding cavity 50 includes a guiding hole 510, a first guiding groove 520, and a second guiding groove 530 formed in the gear fixture 30. The guiding hole 510 is connected to the second guiding groove 530 through the first guiding groove 520. The first conduit 240 is connected to the guiding hole 510. Several oil outlet holes 60 are all connected to the first guiding groove 520. The cross-sections of the first guiding groove 520 and the second guiding groove 530 are both annular. The first guiding groove 520 and the second guiding groove 530 are correspondingly arranged. The lubricating oil enters the guiding hole 510 through the first conduit 240, and then enters the several oil outlet holes 60 through the first guiding groove 520 and the second guiding groove 530 to achieve the application of lubricating oil on the tooth surface of the gear. Furthermore, the outlets of the several oil outlet holes 60 are respectively located on several tooth surfaces of the contour gear groove 40. The oil outlet holes 60 on the several tooth surfaces are staggered and spaced at different heights to improve the application range of the lubricating oil.

[0025] See Figure 2 , 56. The gear fixture 30 includes a base 310, which is mounted on the base 10. During installation, several support rods are fixedly mounted on the bottom of the base 310. Pins are mounted on the bottom of the support rods, and bolts pass through the pins, connecting them to the base 10. An assembly base 320 is mounted on the top of the base 310. A guide hole 510 and a first guide groove 520 are both formed within the base 310, and a second guide groove 530 is formed within the assembly base 320. A contoured gear groove 40 is formed on the assembly base 320. Removing the assembly base 320 from the base 310 allows for the removal of the contoured gear groove 40, exposing both ends of the groove for cleaning. The tooth surface of the profiled gear groove 40 is cleaned. Furthermore, a first sealing ring 70, a second sealing ring 710, and a third sealing ring 720 are installed between the mounting base 320 and the base 310. Specifically, the first sealing ring 70 and the second sealing ring 710 are used to seal the connection between the first guide groove 520 and the second guide groove 530, while the third sealing ring 720 is used to seal the connection between the profiled gear groove 40 and the mounting base 320. The bottom of the profiled gear groove 40 is connected to an oil drain pipe 410, which penetrates the side wall of the mounting base 320. At the same time, an existing valve is installed on the oil drain pipe 410, which can drain the oil in the profiled gear groove 40.

[0026] See Figure 5 A single screw 80 passes between the base 310 and the mounting base 320. A nut 810 is screwed onto the screw 80. During installation, through holes are provided on both the base 310 and the mounting base 320. The two through holes are set in a corresponding manner. The screw 80 is passed through the two through holes, and then the nut 810 is connected to the screw 80, so that the mounting base 320 can be installed on the base 310.

[0027] When using this semi-automatic gear oiling mechanism: place the gear to be lubricated in the conformal gear groove 40, then activate the optical sensor 230. After detecting the presence of the gear, the optical sensor 230 controls the metering valve 220 to open via the existing control module, causing the second conduit 260 of the metering valve 220 to draw lubricating oil from the oil tank 250. The lubricating oil is then transported through the metering valve 220 to the first conduit 240, then into the guide hole 510, and then through the first guide groove 520 into the second guide groove 530. Finally, it is applied to the tooth surface of the gear through several oil outlet holes 60 to achieve the purpose of metered lubricating oil application. After the application is completed, the gear can be removed.

[0028] It should be noted that the specific models and specifications of the metering valve 220, optical sensor 230, and profiled gear groove 40 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0029] The power supply and operating principle of the metering valve 220 and the optical sensor 230 are clear to those skilled in the art and will not be described in detail here.
