Description

Technical Field

[0001] This utility model belongs to the field of automotive parts assembly technology, specifically, it relates to an oiling mechanism. Background Technology

[0002] In the assembly process of automotive door limiters, the traditional lubrication method involves manual operation: the operator uses a cone-shaped tool to scoop up lubricant and evenly apply it to the contact points between the limit arm and the pin, as well as the lubrication points of the limit arm and the sliding block of the rotating parts. This method has the following significant drawbacks:

[0003] 1. Low oiling efficiency: Manual operation is time-consuming and labor-intensive, which cannot meet the needs of large-scale production;

[0004] 2. Poor oiling stability: The amount of oil applied depends on manual experience, which can easily lead to uneven oil application or problems of excessive / insufficient oil application.

[0005] 3. High product quality risk: Dust in the operating environment can easily mix with grease, causing the slider and the limit arm to rub against each other and produce abnormal noise, affecting the sound quality of the door opening and closing.

[0006] 4. Cumbersome process: It requires multiple steps to complete the oiling of different parts, resulting in high equipment investment costs and redundant production process.

[0007] While some automated oiling equipment has attempted to solve the above problems, many of them suffer from drawbacks such as complex structure, insufficient oiling precision, or inability to adapt to the oiling needs of multiple parts of the door limiter. Utility Model Content

[0013] In a preferred embodiment: the oiling nozzle is vertically fixed to the front end of the T-shaped plate to ensure that the oiling direction of the oiling nozzle is perpendicular to the area to be oiled.

[0014] In a preferred embodiment, a return spring is also provided between the cylinder and the T-shaped plate in the cylinder assembly.

[0015] In a preferred embodiment: the front end of the oiling nozzle is provided with a replaceable oil outlet hole. For different hole diameters of the limit arm through hole, the oil outlet hole can be quickly replaced to find a suitable one. Furthermore, the shape of the oil outlet hole can be customized according to the shape of the limiter's oiling hole to meet different oiling needs.

[0016] In a preferred embodiment: a pressure sensor is integrated inside the pipeline to monitor the pipeline pressure in real time and feed it back to the controller.

[0017] In a preferred embodiment: the cylinder assembly and the oil control valve are externally electrically connected to a controller, which controls the oiling path, time, and pressure parameters.

[0029] like Figure 1-2 As shown, this utility model discloses an oiling mechanism, including a tooling base 1, an extension frame 2, a tooling frame 3, a cylinder assembly 4, an oil control valve 5, and an oiling nozzle 6. The tooling frame 3 is fixedly installed at the top center of the tooling base 1. The tooling frame 3 supports the limiter 7 and positions the oiling area. Two symmetrical extension frames 2 are arranged on the left and right sides of the tooling frame 3. The extension frames 2 are fixed to the tooling base 1 by bolts. The height of the extension frames 2 can be adjusted according to the size of the limiter 7 to ensure that the oiling nozzle 6 is at the same level as the area to be oiled. Several cylinder assemblies 4 are fixedly installed on the extension frames 2. The cylinder assemblies 4 can be freely adjusted in position by bolts to adapt to the oiling point requirements of different models of limiters 7. A T-shaped plate is fixedly installed at the cylinder output end of the cylinder assembly 4. The oiling nozzle 6 is vertically fixed to the front end of the T-shaped plate to ensure that the oiling direction of the oiling nozzle 6 is perpendicular to the area to be oiled. The cylinders in the cylinder assembly 4 and the T-shaped plate... A return spring is also provided between them. Through the elastic deformation of the return spring, after the oiling is completed, the oiling nozzle 6 on the T-shaped plate is pulled back to the initial position. The front end of the oiling nozzle 6 is provided with a replaceable oil outlet hole. For different hole diameters of the limit arm through hole, the appropriate oil outlet hole can be quickly replaced. Moreover, the shape of the oil outlet hole can be customized according to the oiling hole shape of the limiter 7 to meet different oiling needs. The side end of the cylinder assembly 4 is fixedly installed with an oil control valve 5. The oiling nozzle 6 and the oil control valve 5 are connected through a pipeline to regulate the flow of lubricating oil. The pipeline integrates a pressure sensor to monitor the pipeline pressure in real time and feed it back to the controller to avoid unstable oil output due to pressure fluctuations. The cylinder assembly 4 and the oil control valve 5 are externally electrically connected to a controller. The controller controls the oiling path, time and pressure parameters. The lubricating oil is output through the oil control valve 5. The controller controls the running time of the oiling nozzle 6 to make the oil output of the nozzle accurate per stroke.

[0030] The fixture 3 includes a housing and a limiting wall. The housing is used to limit and fix the limiter 7 to ensure that the position of the limiter 7 is stable during the oiling process. Limiting arms are fixedly installed on both the left and right sides of the housing. The limiting arms have through holes corresponding to the oiling area of ​​the limiter 7, so that the oiling nozzle 6 can be inserted for precise oiling.

[0031] Working principle

[0032] When this utility model is in operation, the limiter 7 is placed inside the housing of the tooling frame 3, ensuring that the through hole of the limit arm is completely aligned with the area to be oiled (such as the shaft hole or inner wall); the controller controls the cylinders of multiple cylinder assemblies 4 to extend simultaneously, pushing the T-shaped plate to move the oiling nozzle 6 along the direction of the through hole of the limit arm until the oil outlet reaches the surface of the area to be oiled; the pressure sensor detects the pipeline pressure in real time, and if the initial pressure deviates from the preset value, the controller automatically adjusts the opening of the oil control valve 5 until the pressure stabilizes; the controller opens the oil control valve 5 at a preset time, and the lubricating oil is output to the designated part through the oiling nozzle 6. During the oiling process, the pressure sensor continuously monitors the pressure change, and if an abnormality occurs, the oiling is automatically stopped and an alarm is triggered; after the oiling is completed, the cylinder retracts, and the return spring pulls the oiling nozzle 6 back to the initial position.
