Please refer to fig. 1-4. In one embodiment of the present invention, the chip removing apparatus includes: the telescopic cylinder 5, the first electromagnetic valve, the needle head assembly, the air source piece and the communication channel.
Wherein the first solenoid valve is used for controlling the extension and retraction of the extension and retraction cylinder 5. The needle assembly is connected to the piston of the telescopic cylinder 5. The needle assembly is insertable into the bore lumen as the retraction cylinder 5 is extended and is also extractable from the bore lumen as the retraction cylinder 5 is retracted. The air source part stores compressed air for providing air. The communication channel is used for communicating the air source piece and the needle head assembly. The communication channel can be turned on or off. After the needle head component is inserted into the cavity of the hole, the communication channel is communicated. When the communicating channel is conducted, the gas in the gas source piece can be blown into the inner cavity of the hole through the inner cavity of the needle head assembly. The specific structure of the communication passage will be explained hereinafter. When the operation is carried out, the first electromagnetic valve is firstly controlled, the telescopic cylinder 5 carries the needle head assembly to move, the needle head assembly is inserted into the cavity of the hole to be cleaned, then the communication channel is conducted, so that the cavity of the air source piece and the cavity of the needle head assembly are conducted, air in the air source piece is blown into the cavity of the hole through the cavity of the needle head assembly, and scraps in the cavity of the hole are blown out of the cavity of the hole. The chip removing device can automatically remove chips in the inner cavity of the hole, and is time-saving and labor-saving. In addition, the telescopic cylinder 5 is convenient for separating the needle head assembly from the hole inner cavity, and is convenient for taking down the product containing the hole inner cavity from the station.
In order to facilitate the control of the opening and closing of the air source piece, a second electromagnetic valve can be arranged on the air source piece. After the needle head assembly is inserted into the cavity of the hole, the second electromagnetic valve is opened, and the gas in the gas source piece flows out; after the needle assembly is withdrawn from the bore cavity, the second solenoid valve is closed and the air source is closed and no air flows out. The telescopic cylinder 5 can be preferably a cylinder, and the cylinder is convenient for automatic control.
The communication channel can be a flexible gas pipeline, one end of the gas pipeline is communicated with the gas source piece, and the other end of the gas pipeline is communicated with the inner cavity of the needle head assembly. In order to facilitate automatic control of the communication channel, a third solenoid valve may be provided in the communication channel. In this manner, however, the gas conduit may move with movement of the needle assembly, resulting in unstable gas supply. Thus, in one embodiment of the present invention, the following design is made: a blowing block 3 is added. The telescopic cylinder 5 is fixed on the air blowing block through a mounting plate.

An air inlet hole 21 is arranged on the needle head assembly, and the air inlet hole 21 is communicated with the inner cavity of the needle head assembly. After the needle assembly is inserted into the bore cavity, the air inlet 21 of the needle assembly is positioned just at the air outlet of the air inlet channel 31. The flow direction of the gas is: air source piece-air inlet channel 31-air inlet hole 21-needle assembly inner cavity-hole inner cavity. In this embodiment, the air inlet channel 31 and the air inlet 21 form a communication channel for communicating the air source member with the interior cavity of the needle assembly. When the needle assembly is inserted into the bore cavity, the air inlet channel 31 is in communication with the air inlet 21, i.e. the air source is in communication with the needle assembly cavity. When the needle assembly is withdrawn from the bore cavity, the air inlet channel 31 and the air inlet aperture 21 are closed, i.e. the air supply piece and the needle assembly cavity are closed. The communication channel in the form does not move along with the movement of the needle head assembly, and has the advantage of stable air supply.
Further, in order to achieve the sealed communication of the intake passage 31 with the intake hole 21, the following sealing design may be made: two sealing sleeves 4 are arranged in the mating chamber 33.

Two sealing sleeves 4 are distributed on both sides of the air outlet of the air inlet channel 31. The two sealing sleeves 4 enclose a relatively closed inlet chamber 32 between them. The needle assembly is in clearance fit with the sealing sleeve 4, i.e. the needle assembly is capable of reciprocating within the sealing sleeve 4. After the needle assembly is inserted into the bore cavity, the air intake aperture 21 on the needle assembly is located just within the air intake cavity 32. The air from the air supply member flows out of the air inlet channel 31 into the air inlet chamber 32 and then through the air inlet 21 into the interior cavity of the needle assembly. The inlet chamber 32 is relatively closed and gas leakage is largely avoided.
Further, the needle assembly is designed as a movable shaft 2 and a needle 1 for ease of manufacturing. One end of the movable shaft 2 is connected with a piston of the telescopic cylinder 5, and the other end is connected with the needle head 1. The inner cavity of the movable shaft 2 is communicated with the inner cavity of the needle head 1. The air intake hole 21 is provided on the movable shaft 2.
