Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to an oil injection mechanism for a flexible production line of automotive parts with a double-sealed structure. Background Technology

[0002] Automotive parts processing refers to the processing, precision treatment, and assembly of various parts during automobile manufacturing. Due to the complexity, high precision requirements, and wide variety of automotive parts, the parts processing technology involves multiple aspects, including metal processing, plastic processing, heat treatment, and surface treatment. Some automotive parts require oiling during processing, thus necessitating the use of oiling mechanisms.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] In some existing ordinary oil filling mechanisms, a sealing ring is usually installed on the nozzle when in use. The sealing ring is responsible for sealing when the nozzle performs the oil filling operation. However, the sealing performance of a single-layer sealing structure is limited, and oil may still seep out from the gap between the sealing ring and the automotive parts, resulting in oil waste. Utility Model Content

[0005] The purpose of this invention is to provide an oil injection mechanism for a flexible production line of automotive parts with a double-sealed structure, in order to solve the problems mentioned in the background art.

[0009] More preferably, the lower part of the outer wall of the oil tank is provided with a rectangular hole, and an arc-shaped protective glass is provided inside the rectangular hole, and the outer wall of the protective glass is provided with capacity scale lines.

[0010] More preferably, the pump body's inlet is connected to the bottom outlet of the oil storage tank via a pipe, the L-shaped fixing plate has a circular hole at its top, and one end of the connecting pipe passes through the circular hole and is connected to the telescopic hose via the second flow meter electric valve.

[0011] More preferably, the nozzle body is mounted on the inner wall of the mounting ring, and one end of the telescopic hose is connected to the nozzle body.

[0012] More preferably, the nozzle assembly forms a lifting mechanism with the electric push rod via an L-shaped mounting bracket and a mounting ring.

An annular groove 1203 is formed at the bottom of the nozzle body 1201. A plurality of springs 1204 are installed at the top of the inner wall of the annular groove 1203. An annular insert 1205 is installed at the bottom of the springs 1204. A second sealing ring 1206 is installed at the bottom of the annular insert 1205.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, two L-shaped support plates 2 are installed on the top of the base plate 1. A fixing ring 5 is installed at the rear end of the L-shaped support plate 2. An oil storage tank 6 is installed on the inner wall of the fixing ring 5. A first flow meter electric valve 7 is installed on the top of the oil storage tank 6.

[0025] In this embodiment, as Figure 1 As shown, a rectangular hole is provided on the lower part of the outer wall of the oil tank 6, and an arc-shaped protective glass is provided inside the rectangular hole, and the outer wall of the protective glass is provided with capacity scale lines.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the inlet of the pump body 3 is connected to the bottom outlet of the oil storage tank 6 through a pipe. The top of the L-shaped fixing plate 4 has a circular hole, and one end of the connecting pipe 8 passes through the circular hole and is connected to the telescopic hose 14 through the second flow meter electric valve 13.

[0027] In this embodiment, as Figure 1 and Figure 4 As shown, the nozzle body 1201 is installed on the inner wall of the mounting ring 11, and one end of the telescopic hose 14 is connected to the nozzle body 1201.

[0028] In this embodiment, as Figure 1 As shown, the nozzle assembly 12 forms a lifting mechanism with the electric push rod 9 via the L-shaped mounting bracket 10 and the mounting ring 11.

[0029] In this embodiment, as Figure 4 As shown, the annular insert 1205 is slidably installed in the annular groove 1203, and one end of the spring 1204 is connected to the top of the annular insert 1205.

The pump body 3 draws oil from the oil tank 6, and then the oil is injected into the automotive parts through the connecting pipe 8, the telescopic hose 14 and the nozzle body 1201. The oil injection status is checked through the flow meter of the second flow meter electric valve 13. After injecting an appropriate amount of oil, the second flow meter electric valve 13 and the pump body 3 are closed. Then the electric push rod 9 is started, which drives the L-shaped mounting bracket 10, the mounting ring 11 and the nozzle body 1201 to move upward and reset. The remaining oil in the oil tank 6 can be checked through the arc-shaped protective glass on the outer wall of the oil tank 6.
