Technical Field

The invention relates to the technical field of automobile manufacturing, in particular to a silicone oil damper oiling device.

Background

The silicon oil damper structure: the shell and the cover plate form a closed cavity in a welding mode, the inertia ring is located in the cavity and separated from the shell through the bearing, silicone oil is filled in a gap between the inertia ring and the shell, and the inertia ring suspended in the shell generates proper relative motion with the crankshaft under the action of proper damping and rigidity of the silicone oil, so that the torsional vibration amplitude of the crankshaft is reduced.

The proper amount of silicone oil can provide the damping and rigidity required in the working process of the shock absorber and meet the loss of the silicone oil in the long-term working process of the shock absorber.

The existing product oil injection structure comprises two holes, wherein one hole is vacuumized, and the other hole is used for injecting oil. In the actual production process, due to the existence of double holes, the sealing difficulty is increased, the vacuum degree cannot meet the technical requirements, the injection amount of the silicone oil cannot meet the technical requirements, and the performance and the durability of the product are influenced.

Disclosure of Invention

The invention aims to provide an oiling device of a silicone oil damper.

In order to achieve the purpose, the invention adopts the following technical scheme: an oil injection device of a silicone oil damper,

the invention has the beneficial effects that: the device adopts one hole for oil injection, reduces the sealing difficulty, and ensures that the vacuum degree can be more easily reached, thereby improving the injection precision of the injection amount of the silicone oil and ensuring that the device meets the technical requirements of silicone oil injection.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

As shown in fig. 1-3, the oil injection device for the silicone oil damper comprises an equipment rack 1, an upper rack assembly 2, a tray assembly 3, a vacuum tightness injection assembly 4, a quantitative injection assembly 5, a tank body assembly, an oil pipe 6, a degassing tank assembly 7, an oil storage tank assembly 8 and a product 9.

The upper portion rack assembly 2 is arranged above the equipment rack 1, the tray combination 3 is arranged on the equipment rack 1, the product 9 is placed on the tray combination 3, and the vacuum sealing filling combination 4 is connected with the upper portion rack assembly 2 and is suspended above the tray combination 3 to correspond to the position of the product 9.

The vacuum sealing filling combination 4 is connected with an oil storage tank combination 8 through an oil pipe 6, a degassing tank assembly combination 7 is arranged above the oil storage tank combination 8, and a tank body assembly is arranged on the side face of the oil storage tank combination 8.

The vacuum tightness filling combination 4 comprises a chassis, a pressing cylinder 41, a suck-back valve 42, a vacuum pressure sensor 43, a filling valve 44 and an oil filling hole 45. The upper part of the chassis pressing cylinder 41 is connected with the oil pipe 6, an oil filling hole 45 is arranged below the chassis pressing cylinder 41, a suck-back valve 42 and a filling valve 44 are arranged on the chassis in bilateral symmetry, and a vacuum pressure sensor 43 is arranged below the suck-back valve 42.

The working principle is as follows:

two product oil injection holes are changed into one product oil injection hole in the machining process. In the silicone oil filling process, the pressing cylinder 41 presses the workpiece by enabling the vacuum sealing filling mechanism to move up and down, then the product is vacuumized through the oil filling hole, the vacuum pressure sensor 43 measures a vacuum value in the workpiece, the filling valve 44 fills silicone oil after the vacuum value meets the technical requirements, and the suck-back valve 42 sucks back the filled silicone oil to prevent the silicone oil from overflowing.

Has the advantages that:

1. the novel silicone oil filling technology reduces the working hours of single pieces and improves the working efficiency.

2. The novel silicone oil filling technology improves the precision of silicone oil filling amount and the performance and durability of products.

3. This novel silicon oil filling technique has promoted the utilization efficiency of silicon oil, avoids the waste of silicon oil.

4. This novel silicon oil filling technique has reduced the oil filler point number, has reduced follow-up oil filler point and has sealed defect risk.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
