Detailed Description
The invention is described in more detail below with reference to the figures and examples.
The invention discloses a spindle tool holder clamping mechanism with dirty end faces, which is shown in a combined drawing 1-3 and comprises a rotor 4 and a tool holder 5, wherein the rear end of the tool holder 5 is inserted into a front end opening of the rotor 4, an annular shoulder 50 is formed on the outer side wall of the tool holder 5, the annular shoulder 50 is aligned with the front end face of the rotor 4, a plurality of bosses 40 protruding forwards are formed on the front end face of the rotor 4, a gap is formed between every two adjacent bosses 40, a front end air hole 41 is formed on the front end face of each boss 40, a plurality of rotor air passages 42 used for injecting compressed air are formed in the side wall of the rotor 4, the rotor air passages 42 are communicated with the front end air holes 41 in a one-to-one correspondence manner, pull rods 6 are arranged in the rotor 4, a central air passage 60 used for injecting compressed air is formed in the center of each pull rod 6, the front end opening of each central air passage 60 faces the rotor 5, when the tool holder 5 is detached or assembled, the front end face of the rotor 4 and the annular shoulder 50 are cleaned by airflow blown out from the front end air hole 41, and the airflow blown out from the central air passage 60 is blown out from a gap between the inner wall of the rotor 4 and the outer wall of the tool holder 5, so that the rear end face of the tool holder 5 and a gap between the two bosses 40 are cleaned.
In the above structure, when the tool holder 5 is assembled with the front end of the rotor 4, if dirt such as dust and scraps still exist between the front end face of the rotor 4 and the rear end face of the annular shoulder 50, under the action of air flow, the dirt can be temporarily retained between the two bosses 40, and then the end face dirt-hiding effect is achieved, so that the tool holder 5 and the rotor 4 are more tightly combined, thereby ensuring that the spindle has sufficient processing precision, meanwhile, in the process of tool changing or tool unloading, the air flow blown out by the front end air hole 41 can clean the front end face of the rotor 4 and the rear end face of the annular shoulder 50, and in addition, the air flow blown out by the central air passage 60 can be blown out by the gap between the two bosses 40, so as to remove the dirt hidden between the two bosses 40, compared with the tool holder in the prior art, the invention greatly improves the cleanliness between the tool holder 5 and the rotor 4, the spindle keeps the optimal machining precision and better meets the application requirements.
As a preferred configuration, a plurality of bosses 40 are uniformly distributed along the front end face of the rotor 4.
