Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection tools, specifically a self-lubricating automotive parts inspection tool. Background Technology

[0002] Automotive component inspection fixtures are crucial tools for inspecting the quality of automotive parts. Characterized by high precision, their design and manufacturing strictly adhere to relevant standards, enabling accurate measurement of parameters such as the size, shape, and position of components, with an accuracy down to the micrometer level. For example, they provide accurate data when inspecting critical dimensions such as the bore diameter and wall thickness of engine blocks. Various types of fixtures are available, specifically designed for different components. For instance, fixtures for automotive wheel hubs can inspect the wheel hub's contour and bore position; fixtures for automotive interior parts focus on inspecting their appearance and fit. During use, they are relatively simple to operate, providing rapid inspection results and effectively improving production efficiency. Furthermore, they help ensure the consistency of automotive component quality, enhancing the performance and safety of the entire vehicle, making them an indispensable piece of equipment in the automotive manufacturing process. According to the utility model patent with patent authorization announcement number CN222231478U, the automotive parts inspection tool includes a pair of interconnected crossbeams and a pair of longitudinal beams. A rack parallel to the crossbeams is fixed between the pair of longitudinal beams. Multiple longitudinal plates are provided on the pair of crossbeams. A transverse rail is provided on the crossbeams. The two ends of the longitudinal plates are slidably connected to the transverse rails on the pair of crossbeams. A longitudinal shaft is provided below the longitudinal plates. One end of the longitudinal shaft is connected to a drive motor. A gear is fixedly sleeved on the longitudinal shaft. The gear is meshed with the rack. A lead screw is provided on the longitudinal plate. A rotating handle is fixedly sleeved on one end of the lead screw. A sliding block is threadedly connected to the lead screw. The sliding block is slidably connected to the longitudinal groove. A slot is recessed at the top of the longitudinal plate. A scale is provided in the slot.

[0003] Automotive parts inspection fixtures require lubrication to ensure their accuracy and stability during prolonged use. However, many fixtures currently face numerous inconveniences during lubrication. Due to the complex structure and numerous precision parts of the fixtures, lubricant cannot accurately reach all parts requiring lubrication, resulting in poor lubrication effects. Furthermore, the lubrication process often requires disassembling parts of the fixture, which not only consumes a lot of time and effort but also may damage the fixture due to improper operation, affecting the normal progress of subsequent inspection work. This inconvenient lubrication method poses a significant challenge, especially for automotive parts inspection fixtures with extremely high precision requirements. Utility Model Content

[0021] Please see Figure 1-5A self-lubricating automotive parts inspection tool includes a base 1, a mounting seat 2 slidably connected inside the base 1, a motor 21 fixedly mounted on the left side of the base 1, a threaded rod 22 connected inside the base 1 via a bearing, the output end of the motor 21 being rotatably connected to the base 1, and the output end of the motor 21 being fixedly connected to the threaded rod 22. The design of the motor 21 allows it to drive the threaded rod 22 to rotate. The outer side of the threaded rod 22 is provided with positive and negative threads. The threaded rod 22 is threadedly connected to the mounting seat 2, allowing it to move two mounting seats 2. A fixing tube 3 is fixedly connected inside the base 1, and an oil bottle 31 is fixedly connected to the upper end of the fixing tube 3.

[0022] Please see Figure 2-5 A fixing plate 4 is fixedly connected inside the fixing pipe 3. An oil inlet hole 41 is opened inside the fixing plate 4. A sleeve 42 is fixedly connected inside the fixing plate 4. A slide rod 43 is slidably connected inside the sleeve 42. A limit ring 44 is fixedly connected inside the sleeve 42. The limit ring 44 is slidably connected to the slide rod 43. Through the design of the limit ring 44, the slide rod 43 can be limited. A spring 45 is provided inside the sleeve 42. One end of the spring 45 contacts the slide rod 43, and the other end of the spring 45 contacts the sleeve 42. Through the design of the spring 45, the ball 46 can be driven to reset.

[0023] Please see Figure 2-5 A ball bearing 46 is fixedly connected to the end of the slide rod 43 away from the spring 45. The ball bearing 46 is slidably connected to the fixed tube 3. An oil outlet hole 5 is opened inside the mounting base 2. A through hole 51 is opened inside the mounting base 2. The upper end of the mounting base 2 contacts the mounting plate 52. An oil-absorbing cotton 53 is fixedly connected to the lower end of the mounting plate 52. The oil-absorbing cotton 53 is slidably connected to the through hole 51.
