Referring to fig. 3 and 4, a processing apparatus 20 according to another embodiment is shown, where the processing apparatus 20 shown in fig. 3 and 4 differs from the processing apparatus 10 shown in fig. 1 by at least: the processing device 20 is not provided with the sealing assembly 124 between the inner cooling needle 121 and the horn 160, but the processing device 20 includes an adjusting member 500, the adjusting member 500 is sleeved on the front end of the inner cooling needle 121 and is positioned inside the horn 160, the adjusting member 500 is positioned in front of the hollow cylindrical part 155, and the adjusting member 500 is positioned at the rear end of the tool head 400. The adjusting piece 500 is mainly used for reducing the problem that oil mist is accumulated to influence the oil mist transmission efficiency due to long-time application in micro-lubricating internal spraying processing, and improving the transmission efficiency of the micro-lubricating oil mist.

Further, the adjusting member 500 is screwed to the outer side of the front end of the internal cooling pin 121, and when an axially through internal cooling channel is provided in the tool bit 400, the end surface of the adjusting member 500 does not interfere with the axially through internal cooling channel in the tool bit 400. Therefore, the extension or extension length of the tool head 400 can be controlled by controlling the screwing degree of the adjusting piece 500 into the inner cooling pin 121, so as to adapt to workpieces with different height sizes. The adjusting piece improves the transmission efficiency of the trace lubricating oil mist, and meanwhile, the trace lubricating oil mist is prevented from being accumulated near the tool bit mounting hole of the tool holder after long-term use. Also, the efficiency of the transfer of other minute amounts of the lubricating medium into the tool bit 400 can be improved, while the normal coolant is not affected without the adjusting member 500.

Further, the front end of the adjusting member is provided with a fitting hole 510, and the fitting hole 510 is in a hexagon socket shape. Therefore, the adjustment member 500 can be more easily mounted on the front end of the inside cooling pin 121 by engaging the hexagonal tool with the hexagonal socket-shaped engagement hole 510. The middle part of adjusting part 500 has still seted up the annular groove, and the annular groove is used for holding the sealing washer, improves sealing performance.

Furthermore, the front end of the side wall of the matching hole 510 is in the shape of an outward-expanding arc to be adapted to the rounded structure at the rear end of the tool head 400, so that the tool head 400 is more attached to the inner-cooling tool shank 100 after being assembled, and the cooling medium is more easily drained

Compared with the traditional inner-cooling tool holder 100, the inner-cooling tool holder 100 is not provided with an inner-cooling needle seat in the front cavity, but adopts a structure that the sealing joint 122 and the inner-cooling needle 121 are both installed in the assembling hole 111 at the rear end of the tool holder body 110, so that the inner-cooling tool holder 100 only needs to install the sealing joint 122 and the inner-cooling needle 121 to the tool holder body 110 from the rear end, and does not need to additionally install the inner-cooling needle seat in the front cavity, thereby being more convenient to install, saving time and labor, and ensuring the sealing performance.
