Background
At present, in the machining process of a core-moving lathe, the machining of a power head of the core-moving machine is exposed to a multi-oil environment for a long time. Due to the rotation of the power head, a certain clearance must be ensured between the shaft and the seat. Therefore, during long-time machining, cutting oil can enter the main shaft due to the severe environment of the cutting chamber, and the bearing in the power head is damaged. In the large environment of the processing industry, the processing efficiency is one of the survival laws of enterprises. Traditional fold ring seal circle and skeleton sealing washer seal structure are difficult to prevent cutting oil from getting into inside the main shaft. The air pipes in the market are in one-to-one air blowing sealing mode, so that the whole air path is complex, and the risk of damaging the air pipes is high. If the oil is fed to cause the damage to the whole machine tool, the whole machine tool can not work for a long time, so that the machining efficiency is reduced.

In order to achieve the above object, the technical solution of the present utility model is: the utility model provides a walk heart quick-witted unit head integrated form airtight structure, is provided with the sealing washer that prevents gas leakage including installing in unit head and main knife rest intercommunication department, install a plurality of fixed power shaft and plug-in power shaft on the unit head, its characterized in that: the inside upper end of unit head is provided with air current main way A, and the inside lower extreme of unit head is provided with air current main way B, air current main way A's one end is linked together with the sealing washer, and air current main way A's the other end is linked together with the air current branch road, the air current branch road has a plurality of branch road export with fixed power shaft one-to-one, the branch road export is linked together with fixed power shaft is inside.
One end of the air flow main path B is communicated with the sealing ring, the other end of the air flow main path B is communicated with the air flow channel, the air flow channel is communicated with the power shaft air flow channel inside the pluggable power shaft, and the air flow channel is provided with an M8 threaded plug capable of plugging the air flow main path B.
The air flow branch is also provided with a plurality of branch outlets which are respectively plugged by 1/8 screw plugs and M4 screw plugs.
Compared with the prior art, the utility model has the beneficial effects that:
1. according to the utility model, two main air flow paths are respectively arranged near the two sets of power shafts, and then the air flow branches are separated from the main air flow paths to blow air into the power shafts, so that cutting oil can be effectively prevented from entering, and the core components are protected from damage; because the air passage is arranged near the power shaft, the structure of the air passage is simplified, and the airtight effect is improved.
2. According to the utility model, the threaded plug capable of plugging the air flow main passage B is arranged on the air flow passage, so that a corresponding airtight mode can be selected according to different types of pluggable power shafts, and the use is more flexible.
Drawings
Fig. 1 is a schematic structural view (perspective view) of the present utility model.
Fig. 2 is a partial cross-sectional view of a pluggable power shaft portion of the present utility model.
In the figure: the device comprises a power head 1, a sealing ring 2, an airflow branch 101, a branch outlet 102, an airflow main path A107, an airflow main path B108,1/8 threaded plug 201, an airflow channel 203, a power shaft airflow channel 205, a fixed power shaft 207, a plug-in power shaft 208, a threaded plug 209 and an M4 threaded plug 301.
Description of the embodiments
The utility model is described in further detail below with reference to the accompanying drawings and detailed description.
Referring to fig. 1-2, an integrated airtight structure of a power head of a heart-moving machine comprises a sealing ring 2 which is arranged at a communication position between a power head 1 and a main cutter seat and used for preventing gas leakage, a plurality of fixed power shafts 207 and plug-in power shafts 208 are arranged on the power head 1, an air flow main path A107 is arranged at the upper end inside the power head 1, an air flow main path B108 is arranged at the lower end inside the power head 1, two air holes are reserved in the main cutter seat and just aligned with the air flow main path A107 and the air flow main path B108 of the power head 1, one end of the air flow main path A107 is communicated with the sealing ring 2, the other end of the air flow main path A107 is communicated with an air flow branch 101, the air flow branch 101 is provided with a plurality of branch outlets 102 which are in one-to-one correspondence with the fixed power shafts 207, and the branch outlets 102 are communicated with the inside of the fixed power shafts 207. The gas flow branch 101 also has a plurality of branch outlets which are respectively plugged by a 1/8 threaded plug 20 and an M4 threaded plug 301. The 1/8 screw plug 20 is an expansion reserved port, so that other functional power heads can conveniently borrow gas from the expansion reserved port, the M4 screw plug 301 is fixed and not detached, the M4 screw bottom hole is phi 3.2, the M4 screw is designed for controlling the gas flow, and drilling processing is required to be carried out from an outlet of the M4 screw plug when the gas flow branch 101 is processed, so that the loop can be conveniently communicated.
One end of the air flow main path B108 is communicated with the sealing ring 2, the other end of the air flow main path B108 is communicated with the air flow channel 203, the air flow channel 203 is communicated with a power shaft air flow channel 205 inside the plug-in power shaft 208, and a threaded plug 209 capable of plugging the air flow main path B108 is arranged on the air flow channel 203.
The working process of the utility model is as follows: after entering the main airflow path A107, the airflow is diffused to the airflow branch 101, all air outlets of the airflow branch 101 are blocked by using the M4 threaded plugs 301, the airflow is fully collected in the whole airflow branch 101, and finally the airflow is blown out from the branch outlet 102, so that the inside of the fixed power shaft 207 is just blown. Because the plug-in power shaft 208 can be installed by selecting different plug-in power shafts, different airtight modes can be selected when the plug-in power shaft 208 with different types is installed, if the plug-in power shaft 208 selects one to three plug-in power shafts, the M8 threaded plug 209 can be screwed to be overlapped with the air flow main path B108 to block the air flow in the air flow main path B108, and meanwhile, the 1/8 threaded plug 201 is taken down and replaced by an air pipe connector to be directly connected to one to three plug-in power shafts. If the plug-in power shaft 208 selects a single power shaft, the M8 threaded plug 209 is screwed to be out of coincidence with the air flow main path B108, so that the air flow in the air flow main path B108 enters the air flow channel 203 and the power shaft air flow channel 205.
