Description

Technical fields:

[0001] This invention relates to the technical field of instrument panel bracket water blowing devices, and more specifically to an automatic cleaning and water blowing device for instrument panel brackets. Background technology:

[0002] Currently, magnesium-aluminum alloy car dashboard brackets are generally formed by casting. After casting, the dashboard bracket still needs to be machined to obtain the finished bracket. For example, the assembly dimensions of the dashboard bracket are processed by milling or the mounting holes are processed by drilling and milling. The machined dashboard bracket usually carries chips and cutting fluid. The current method of handling the chip removal is to immerse the dashboard bracket in a cleaning water tank, and then manually blow water to remove the chips after taking it out. Manual blowing water to remove chips is quite troublesome. Moreover, sometimes the dashboard bracket may encounter oil stains during machining or disassembly and assembly. The above methods cannot remove the oil stains on the dashboard bracket. Therefore, some people have proposed to use ultrasonic cleaning to replace water immersion for chip removal. The dashboard bracket can be placed in an ultrasonic cleaning tank for cleaning, but it needs to be placed for a period of time and then taken out for manual blowing water. The whole process is even more troublesome. Therefore, it is necessary to design a device that can be used in conjunction with an ultrasonic cleaning tank for automatic cleaning and blowing water. Summary of the Invention:

The hinge support shaft 231 is pivotally connected to the pool walls on both sides of the ultrasonic cleaning pool 1. An isolation cover 24 with a longitudinal section of arc shape is sleeved on the outer side of the turntable 23, the core cylinder 21 and the partitions 22.

The two sides of the isolation cover 24 are respectively fixed to the inner side walls on both sides of the ultrasonic cleaning pool 1.

[0033] The hinged support shaft 231 on one side of the instrument panel bearing rotary frame 2 extends out of the ultrasonic cleaning tank 1 and is connected to a rotary drive mechanism 5.

[0037] An air source is connected to the air intake pipe 27 via a pipeline. The air source is a high-pressure centrifugal fan. The air inlet of the high-pressure centrifugal fan is connected to the exhaust pipe 63 via a pipeline. That is, the air outlet of the high-pressure centrifugal fan is connected to the air intake pipe 27 via a pipeline to achieve airflow circulation.

[0038] The air intake pipe 27 extends out of the ultrasonic cleaning tank 1 and is fixedly connected to a longitudinal limiting plate 28. The front and rear ends of the limiting plate 28 are respectively fixedly connected to connecting columns 29. The connecting columns 29 are fixedly connected to the instrument panel bearing rotating frame 2. The rotation of the air intake pipe 27 is restricted by the limiting plate 28.

The rotating shaft of the servo motor 53 is inserted and fixed inside the drive gear 52. The servo motor 53 drives the core cylinder 21 to rotate intermittently.

[0040] The diameter and number of teeth of the driving gear 52 are smaller than those of the driven gear 51, and the driven gear 51 has several weight-reducing holes formed on it.

[0041] The central axis of the core cylinder 21, the central axis of the turntable 23, the central axis of the hinged support shaft 231, the central axis of the central air intake pipe 25, the central axis of the air intake pipe 27, and the central axis of the isolation cover 24 on the instrument panel bearing rotating frame 2 are all on the same straight line.

[0042] At least six partitions 22 are provided, and the partitions 22 are evenly distributed in a ring around the central axis of the core cylinder 21. Thus, the partitions 22 divide at least six cavities, so the upper part of the core cylinder 21 has at least three cavities. These three cavities can be set as a feeding cavity, a taking-out cavity, and a water blowing cavity from front to back. At the same time, the arc of the opening of the isolation cover 24 is required to be equal to the total arc of two adjacent cavities, so that the instrument panel bracket can be taken out and put in from the taking-out cavity and the feeding cavity.

[0043] The water blowing channels 211 are linearly and transversely evenly distributed on the core cylinder 21 and are uniformly arranged in a ring around the central axis of the core cylinder 21;

[0044] The through groove 241 and the water passage groove 221 are linearly and horizontally evenly distributed on the isolation cover 24 and the partition plate 22, respectively.

[0045] The outer wall of the turntable 23, the outer end face of the partition 22, and the inner wall of the isolation cover 24 are all within the same cylindrical surface.

[0046] The instrument panel support rotating frame 2 has several longitudinal elastic baffles 7 between adjacent partitions 22. The two ends of the elastic baffles 7 abut against the adjacent partitions 22 and form limit plugs 71. The limit plugs 71 are inserted into the water channel 221 and located at the outer end of the water channel 221. The elastic baffles 7 can be inserted into or removed from the partitions 22 by bending. In order to avoid wear when the instrument panel bracket moves against the inner wall of the isolation cover 24, the elastic baffles 7 can be used to constrain the instrument panel bracket and isolate the instrument panel bracket and the isolation cover 24.

[0047] The ultrasonic cleaning tank 1 has a storage box 8 fixed to its front end surface, which is opposite to the elastic baffle 7, and the elastic baffle 7 is inserted into the storage box 8.

[0048] An inclined front baffle 4 is inserted and fixed inside the inlet of the ultrasonic cleaning tank 1 on the front side of the instrument panel bearing rotating frame 2, and the rear side of the front baffle 4 abuts against the side of the front end of the isolation cover 24.

[0049] Working Principle: This structure is an automatic cleaning and water-blowing device for instrument panel supports. Its main technical feature is that an instrument panel support rotating frame 2 is set up inside the ultrasonic cleaning tank 1. The instrument panel supports can be placed between the partitions 22 of the instrument panel support rotating frame 2. The rotation of the core cylinder 21 drives the instrument panel supports to move to the lower part of the instrument panel support rotating frame 2 for ultrasonic cleaning. After cleaning, they move to the upper rear part of the instrument panel support rotating frame 2. The air source blows water onto the instrument panel supports through the air inlet pipe 27, the central air inlet pipe 25, and the water-blowing guide hood 26. Instrument panel supports can be set up inside the instrument panel support rotating frame 2. Different instrument panel supports are cleaned and blown water separately, and the water-blowing process can be effectively completed during the cleaning time.

[0050] The second technical point is reflected in the exhaust pipe 6 and the water blowing exhaust box 3. The water blowing exhaust box 3 and the exhaust pipe 6 can prevent water droplets generated by the water blowing from splashing. The water on the instrument panel bracket enters the water blowing exhaust box 3 with the airflow. Due to gravity, some of the water droplets will hit the inner wall of the water blowing exhaust box 3 and flow down the inner wall of the water blowing exhaust box 3 into the ultrasonic cleaning tank 1. At the same time, some water droplets will enter the exhaust pipe 6 through the discharge groove 341 and hit the inner wall of the inclined exhaust pipe 61. After the airflow hits the pipe, it will be discharged along the upper end of the exhaust pipe 6, while the water droplets will move along the inner wall of the inclined exhaust pipe 61 to the lower end of the inclined exhaust pipe 61 and flow back into the ultrasonic cleaning tank 1 through the return hole 342. This can effectively prevent the ground around the water blowing station from being wet.

[0051] The embodiments described are illustrative of the invention and are not intended to limit the invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
