Description

Technical Field

[0001] This application relates to the field of polishing machine technology, and in particular to a rotatable polishing machine that can apply polishing liquid. Background Technology

[0002] The front of a high-speed train is made of fiberglass. Fiberglass is a composite material formed by multiple layers of bonding. After the fiberglass high-speed train front is bonded or assembled, it needs to be polished. In existing technology, polishing is performed by a drive device that drives a polishing brush. During the polishing process, the drive device needs to be stopped frequently to allow polishing fluid to be added to the polishing brush, thus switching between processes affects work efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following is in conjunction with the appendix Figure 1-2This application provides a further detailed description. An embodiment of this application discloses a rotatable polishing machine with polishing liquid, comprising a fixed part 1 and a rotating part 2 rotatably connected to the fixed part 1. The rotating part 2 extends away from the rotating part 2 via a rotating shaft 201 and is connected to a polishing brush 202. The rotating part 2 also has a liquid inlet 203 in the direction away from the rotating part 2. A motor can be installed inside the rotating part 2, or installed inside the fixed part 1 and connected to the rotating shaft 201 inside the rotating part 2 via a conventional transmission method. A liquid inlet pipe is provided inside the rotating part 2, connecting the liquid inlet 203 to the contact surface between the rotating part 2 and the fixed part 1. The fixed part 1 has a liquid delivery port 101 corresponding to the position of the liquid inlet pipe. With the fixed part 1 remaining fixed, the rotating part 2 alone allows switching between two working modes: polishing with the polishing brush 202 and spraying polishing liquid through the liquid inlet 203, targeting the polishing area. When the rotating part 2 rotates, causing the polishing brush 202 to deviate from its original working position, the inlet 203 is aligned with the original working position to replenish the polishing fluid. Then, the rotating part 2 rotates back to the original working position to continue polishing. The rotating part 2 is equipped with an inlet pipe, and the fixed part 1 has an inlet 101. The inlet 203 can only connect to the inlet 101 when the inlet pipe is aligned with it, thus automatically opening or closing the inlet 101 to deliver polishing fluid while changing the working mode. The inlet 203 can also be connected to various multi-hole nozzles to achieve more forms of polishing fluid spraying.

[0021] Furthermore, in order to achieve continuous operation more effectively after switching working modes, the rotation axis of the polishing brush 202 and the center point of the infusion port 203 are in the same cross section of the rotating part 2, so that the position pointed to by the rotation axis of the polishing brush 202 directly becomes the position aligned with the infusion port 203 after the rotating part 2 rotates.

[0022] Furthermore, to improve the sealing between the infusion tubing and the infusion port 101, the infusion port 101 is provided with a hollow frustum-shaped insertion block 3. The smaller base of the insertion block 3 passes through the infusion port 101 and is inserted into the infusion tubing, while the larger base of the insertion block 3 is connected to the fixing part 1 by a spring. Based on the inclined surface of the frustum-shaped outer surface of the insertion block 3, when the rotating part 2 rotates and causes the infusion tubing to disengage from the alignment state with the infusion port 101, the edge of the infusion tubing presses against the inclined surface of the insertion block 3, causing the insertion block 3 to retract away from the rotating part 2 and toward the infusion port 101. When the infusion port 101 is aligned with the infusion tubing, the insertion block 3 automatically inserts into the infusion tubing due to the elastic force of the spring.

[0023] Furthermore, the small bottom surface of the insertion block 3 is provided with an elastic layer to improve the sealing performance of the contact surface between the insertion block 3 and the rotating part 2, and to reduce wear on the small bottom surface of the insertion block 3 due to prolonged rotation of the rotating part 2. Alternatively, an elastic layer can be provided on the contact surface between the rotating part 2 and the fixed part 1 to further improve the sealing performance between the rotating part 2 and the fixed part 1. This also improves the sealing performance of the contact surface between the insertion block 3 and the rotating part 2, reducing wear on the small bottom surface of the insertion block 3 due to prolonged rotation of the rotating part 2, and also reducing wear between the rotating part 2 and the fixed part 1. Both methods can be applied individually or simultaneously depending on the actual situation.

[0024] Furthermore, the area of ​​the base of the insertion block 3 is larger than the area of ​​the liquid delivery port 101, so that the liquid delivery port 101 has a limiting function to prevent the insertion block 3 from extending too far into the infusion pipeline, which would cause the insertion block 3 to fail to rebound smoothly when the rotating part 2 rotates.

[0025] Furthermore, a handle 204 is provided on the outer side of the rotating part 2 to improve the operability of the rotating part 2.

[0026] Furthermore, a locking mechanism is provided between the rotating part 2 and the fixed part 1, such as a locking pin, a buckle or other conventional locking mechanism, to fix the rotating part 2 in the required working mode.

[0027] Working principle: Connect the polishing fluid delivery pipe to the delivery port 101 and align the pipe opening with the rotating part 2. Rotate the rotating part 2 to align the delivery port 101 with the delivery pipe. Rotating the rotating part 2 disengages the delivery pipe from the alignment position with the delivery port 101, activating the polishing brush 202 to begin polishing. When polishing fluid needs to be sprayed, rotate the rotating part 2 to align the delivery pipe with the delivery port 101, thus achieving the polishing fluid spraying function. By continuously rotating the rotating part 2 using the handle 204, the polishing mode and the polishing fluid spraying mode can be switched back and forth. When equipped with the insertion block 3, simply connect the polishing fluid delivery pipe to the base of the insertion block 3.
