Description

Technical Field

[0001] This application relates to the field of mechanical lubrication, and in particular to a device for applying lubricating oil to gear shafts. Background Technology

[0002] An electric mechanism is an automated mechanism that uses an internal motor for drive and gear transmission to achieve specific actions, such as the cable-driven electric mechanism in a car. During the assembly of an electric mechanism, lubricant needs to be applied to specific locations on the rotating shaft of the gear shaft to ensure smooth movement when it is inserted and mated with the sleeve component.

[0003] Currently, applying lubricant to gear shafts mainly relies on manual operation. Due to the small size of the parts, manual lubrication is prone to positional errors, resulting in inaccurate application of lubricant, significant waste, and consequently affecting assembly quality and efficiency. Furthermore, manual operation makes it difficult to ensure consistent and sufficient application, increasing uncertainty and cost during the assembly process.

[0004] The aforementioned technologies suffer from drawbacks such as lubricant waste, low assembly efficiency, and unstable quality due to the low precision of manual operation. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a device for applying lubricating oil to gear shafts, which can realize automated and high-precision operation of applying lubricating oil to gear shafts, thereby improving assembly efficiency and reliability.

[0006] This application is achieved through the following technical solution: A device for applying lubricating oil to a gear shaft includes a mounting plate and a drive mechanism. The mounting plate is provided with an oil injection component. The lower end of the oil injection component abuts against a positioning sleeve. The positioning sleeve has an oil injection hole at the position where it abuts against the oil injection component, and the positioning sleeve has a positioning hole communicating with the oil injection hole along its axial direction. The oil injection component is used to inject lubricating oil into the oil injection hole. The drive mechanism is used to drive the gear shaft to move, so that the rotating part of the gear shaft is inserted into a predetermined position of the positioning hole to apply the lubricating oil injected through the oil injection hole.

[0007] By adopting the above technical solution, the oil injection component and the positioning sleeve are integrated in a design that, together with the drive mechanism, controls the positioning of the gear shaft, achieving precise injection and application of lubricating oil. The oil injection component supplies oil to the positioning hole through the oil injection hole of the positioning sleeve, and the drive mechanism drives the gear shaft to insert into the positioning hole, so that the rotating part contacts the lubricating oil at a predetermined position. This reduces the positional deviation and waste of manual oiling, and improves the consistency and efficiency of oiling.

[0008] Optionally, the mounting plate is provided with a positioning base, and the oil injection component and the positioning sleeve are both fixed on the positioning base.

[0009] By adopting the above technical solution, the positioning base provides a stable installation foundation for the oiling component and the positioning sleeve, ensuring that the relative position between the oiling hole and the positioning hole is fixed, which helps to improve the accuracy and repeatability of the oiling position and reduce the oiling deviation caused by component shaking.

[0010] Optionally, the driving mechanism includes a cylinder, a guide rail, and a slide; the guide rail is disposed on the mounting plate, the slide is slidably connected to the guide rail, and the cylinder is used to drive the slide to perform linear reciprocating motion on the guide rail.

[0011] By adopting the above technical solution, the cylinder drives the slide to move along the guide rail, realizing the automatic feeding and retraction of the gear shaft. The structure is simple and the operation is reliable, which helps to improve operating efficiency, reduce manual intervention, and is suitable for mass production scenarios.

[0012] Optionally, the guide rail has an I-shaped cross-section.

[0013] By adopting the above technical solution, the I-shaped guide rail has good rigidity and guiding accuracy, which can effectively limit the deviation of the slide table during the movement, ensure the centering of the gear shaft when it is inserted into the positioning hole, and improve the positioning stability.

[0014] Optionally, the slide is provided with a working positioning block, which is used to place and position the gear shaft.

[0015] By adopting the above technical solution, the working positioning block provides a dedicated installation position for the gear shaft, which facilitates quick clamping and positioning, reduces installation and adjustment time, and improves the consistency and convenience of operation.

[0016] Optionally, the working positioning block is provided with a first positioning groove, which is adapted to the gear part of the gear shaft to restrict the axial movement of the gear shaft on the working positioning block.

[0017] By adopting the above technical solution, the first positioning groove matches the shape of the gear part, which can effectively limit the axial movement of the gear shaft, prevent it from shifting during movement, and ensure the accuracy of the oiling position.

[0018] Optionally, the front and rear lips of the first positioning groove are provided with a second positioning groove adapted to the gear shaft shaft portion, which is used to restrict the gear shaft from moving radially on the working positioning block.

[0019] By adopting the above technical solution, the second positioning groove constrains the rotating shaft from the radial direction, reducing the shaking or rotation of the gear shaft during movement, and further improving the positioning accuracy and oiling stability.

[0020] Optionally, the bottom of the second positioning groove has an arc-shaped structure.

[0021] By adopting the above technical solution, the arc-shaped bottom fits well with the outer circular surface of the rotating shaft, reducing local stress concentration, avoiding damage to the surface of the parts, and enhancing the stability and reliability of positioning.

[0022] Optionally, the working positioning block can abut against the side wall of the positioning sleeve under the drive of the slide table, so that the rotating shaft can be accurately inserted into the positioning hole.

[0023] By adopting the above technical solution, after the working positioning block abuts against the side wall of the positioning sleeve, the gear shaft can be accurately aligned and inserted into the positioning hole, realizing precise control of the oiling position and effectively avoiding the waste of lubricating oil caused by misalignment.

[0024] Optionally, the oiling component is an oiling gun, and the oil outlet of the oiling gun is connected to the oiling hole of the positioning sleeve.

[0025] By adopting the above technical solution, the oil gun, as a common oil injection device, is easy to control and maintain. Its oil outlet is directly connected to the oil injection hole, which ensures that the lubricating oil can be accurately and stably injected into the predetermined position, thus improving the reliability and efficiency of oil injection.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application integrates the oil injection component with the positioning sleeve and uses a drive mechanism to precisely position and move the gear shaft, thereby achieving automated and targeted application of lubricating oil, effectively solving the problems of inaccurate positioning, grease waste and low efficiency in manual oiling. 2. This application achieves multi-directional limiting and stable guidance of the gear shaft during movement by setting a working positioning block with specific positioning grooves and slots, and combining it with a high-rigidity I-beam guide rail, thereby further ensuring the accuracy of the oiling position and the consistency of the operation process. 3. The structure of this application is reasonable, and the coordinated action of various components such as the positioning base and the oil gun makes the device have the advantages of convenient operation, reliable positioning and convenient maintenance, and it is suitable for mass production application in the assembly process of electric mechanisms.

Detailed Implementation

[0029] The following will be combined with the appendix Figure 1 To be continued Figure 3 The technical solutions of the various embodiments of this application have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Example 1 Reference Figure 1 and Figure 2 This application discloses a device for applying lubricating oil to a gear shaft 5, including a mounting plate 1 and a drive mechanism 2. The mounting plate 1 is provided with an oil injection component 3. The lower end of the oil injection component 3 abuts against a positioning sleeve 4. The positioning sleeve 4 has an oil injection hole 41 at the position where it abuts against the oil injection component 3, and the positioning sleeve 4 has a positioning hole 42 communicating with the oil injection hole 41 along its axial direction. The oil injection component 3 is used to inject lubricating oil into the oil injection hole 41. The drive mechanism 2 is used to drive the gear shaft 5 to move, so that the rotating shaft part 51 of the gear shaft 5 is inserted into the predetermined position of the positioning hole 42 to apply the lubricating oil injected through the oil injection hole 41.

[0031] Specifically, refer to Figure 1 and Figure 2 The lubrication component 3 is preferably an automatic lubricating gun 31, which typically consists of a gun body, a control solenoid valve, and an oil outlet. An external control system triggers the internal solenoid valve to automatically and quantitatively inject lubricating oil. The gun body is generally made of metal to ensure its strength and durability. The oil outlet of the lubricating gun 31 is connected to the oil filling hole 41 of the positioning sleeve 4, ensuring that the lubricating oil accurately enters the oil filling hole 41. Alternatively, the lubrication component 3 can be replaced by an oil pump or other equipment. The oil pump can be driven by a motor to achieve continuous and stable oil injection.

[0032] Reference Figure 1 and Figure 2The positioning sleeve 4 is generally made of wear-resistant metal material, such as stainless steel. Its internal positioning hole 42 is adapted to the rotating shaft part 51 of the gear shaft 5, ensuring smooth insertion of the gear shaft 5. The oil filling hole 41 is located at the contact point between the positioning sleeve 4 and the oil filling component 3, through which lubricating oil flows into the positioning hole 42. The contact point between the positioning sleeve 4 and the oil filling component 3 can be sealed with a sealing gasket or similar material to prevent lubricating oil leakage. The positioning sleeve 4 and the oil filling component 3 are fixed to the positioning base 11 on the mounting plate 1 by bolts or other means to ensure stability.

[0033] Reference Figure 1 and Figure 2 The drive mechanism 2 includes a cylinder 21, a guide rail 22, and a slide 23. The cylinder 21 generally consists of a cylinder body, a piston, and a piston rod. The cylinder body is typically made of aluminum alloy to reduce weight. The piston moves linearly within the cylinder body, transmitting power to the slide 23 via the piston rod. The guide rail 22 is mounted on the mounting plate 1 and has an I-shaped cross-section, providing good strength and guidance. The slide 23 is slidably connected to the guide rail 22 and has a working positioning block 24 for placing and positioning the gear shaft 5. The working positioning block 24 can be fixed to the slide 23 using bolts or other methods.

[0034] Reference Figure 3 The working positioning block 24 is provided with a first positioning groove 241, which is adapted to the gear part 52 of the gear shaft 5. The shape of the first positioning groove 241 is designed according to the shape of the gear part 52 of the gear shaft 5, and is generally a shape that matches the gear contour, used to restrict the axial movement of the gear shaft 5 on the working positioning block 24. The front lip and rear lip of the first positioning groove 241 are provided with a second positioning groove 242 adapted to the rotating shaft part 51 of the gear shaft 5. The bottom of the second positioning groove 242 has an arc-shaped structure. This arc-shaped structure can better fit the rotating shaft part 51 of the gear shaft 5, used to restrict the radial movement of the gear shaft 5 on the working positioning block 24. Under the drive of the slide table 23, the working positioning block 24 can abut against the side wall of the positioning sleeve 4, so that the rotating shaft is accurately inserted into the positioning hole 42.

[0035] Reference Figures 1 to 3 The combination logic of the oiling component 3, the positioning sleeve 4, and the drive mechanism 2 is as follows: the oiling component 3 injects lubricating oil into the oiling hole 41 of the positioning sleeve 4, and the drive mechanism 2 drives the gear shaft 5 to move, so that the rotating part 51 of the gear shaft 5 is inserted into the positioning hole 42, thereby allowing the gear shaft 5 to be coated with lubricating oil. This combination method makes the oiling process more automated and precise, improving the uniformity and efficiency of oiling. The oiling component 3 provides lubricating oil, the positioning sleeve 4 provides the position and channel for oiling the gear shaft 5, and the drive mechanism 2 realizes the movement and positioning of the gear shaft 5. The three work together to complete the oiling work of the gear shaft 5.

[0036] The implementation principle of this embodiment is as follows: This embodiment achieves automation and precision in applying lubricating oil to the gear shaft 5 through a reasonable combination of the oil injection component 3, the positioning sleeve 4, and the drive mechanism 2. Compared with traditional manual application, oil bath lubrication, and spray lubrication methods, this device can ensure the uniformity of oil application and reduce local insufficient or excessive lubrication. At the same time, due to the positioning method of the positioning sleeve 4 and the working positioning block 24, the oil application position of the gear shaft 5 is more accurate, improving the quality of oil application. Moreover, the structure of this device is relatively simple, the equipment cost and maintenance cost are low, and the waste of lubricating oil is reduced. It has high practicality and economic benefits, and effectively improves and enhances the existing gear shaft 5 lubrication technology.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this application.
