Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, a milling machine convenient to change milling cutter, including milling machine main part 1, milling cutter anchor clamps 2 are equipped with at the top of milling machine main part 1, milling cutter 3 is equipped with to milling cutter anchor clamps 2 inside, milling cutter anchor clamps 2's surface is equipped with a plurality of and is central symmetric distribution's rotation groove 5, every rotation groove 5's inside all rotates through pivot 9 and is connected with dwang 6, specifically, pivot 9 and rotation groove 5 inner wall fixed connection, pivot 9 rotates with dwang 6 to be connected, milling cutter anchor clamps 2's surface cover is equipped with carousel 4, specifically, carousel 4 and milling cutter anchor clamps 2 sliding connection, the inner wall of carousel 4 is equipped with spout 7, the tip that dwang 6 extends to the milling cutter anchor clamps 2 outside is equipped with the guide post 8 with spout 7 looks adaptation, specifically, dwang 6 rotates with guide post 8 to be connected, guide post 8 and spout.

The scheme has the following working processes:

when the milling cutter 3 of the milling machine is installed, the milling cutter fixture 2 of the milling machine is rotated, the fixture is loosened, the milling cutter 3 is inserted into the milling cutter fixture 2, the milling cutter fixture 2 is reversely rotated, the milling cutter 3 is preliminarily fixed, at the moment, the turntable 4 is continuously pushed to move up and down, the turntable 4 drives the rotating rod 6 to rotate, when the rotating rod 6 rotates, the guide post 8 slides in the chute 7, the guide post 8 rotates relative to the rotating rod 6, the top end of the rotating rod 6 continuously knocks on the top of the milling cutter 3, the milling cutter 3 is vibrated, a gap between the milling cutter 3 and the milling cutter fixture 2 is loosened, at the moment, the milling cutter fixture 2 is rotated again, the milling cutter fixture 2 is clamped more firmly, when the milling cutter 3 is replaced after being used, the milling cutter fixture 2 is loosened, the milling cutter 3 can not be directly taken down due to the clamping with, the milling cutter 3 is easy to remove.

According to the working process, the following steps are known:

constantly pushing the turntable 4 to move up and down, the turntable 4 drives the rotating rod 6 to rotate, when the rotating rod 6 rotates, the guide post 8 slides in the chute 7, the guide post 8 rotates relative to the rotating rod 6, the top end of the rotating rod 6 constantly strikes the top of the milling cutter 3, the milling cutter 3 is vibrated, a gap between the milling cutter 3 and the milling cutter clamp 2 is loosened, at the moment, the milling cutter clamp 2 is rotated again, the milling cutter clamp 2 is clamped more firmly, compared with the prior art, when the milling cutter 3 is installed on the milling cutter clamp 2, the milling cutter 3 is directly fixed in the milling cutter clamp 2, the milling cutter 3 is likely to be clamped temporarily due to small deviation of a vertical position, the milling cutter clamp 2 is easy to loosen when in work, the use of the milling cutter 3 is influenced, after the milling cutter 3 is clamped, the milling cutter 3 strikes through the rotating rod 6, the milling cutter 3 is vibrated, it is tight to rotate anchor clamps again, further press from both sides, milling cutter 3's centre gripping is more stable, make things convenient for milling cutter 3's use more, when milling cutter 3 finishes using the back change, loosen milling cutter anchor clamps 2, milling cutter 3 probably can not directly take off because it is too tight with milling cutter anchor clamps 2 centre gripping, at this moment, continuous promotion carousel 4 again, carousel 4 drives dwang 6 constantly strikes milling cutter 3, milling cutter 3 takes out easily, for among the prior art, when milling cutter 3 takes out, directly rotate milling cutter anchor clamps 2, milling cutter 3 probably blocks in milling cutter anchor clamps 2, milling cutter 3 is inconvenient to take out, this scheme is after milling cutter anchor clamps 2 loosen milling cutter 3, the vibrations power that provides through dwang 6, strike out milling cutter 3, make things convenient for milling cutter 3's taking out more, it is more convenient to use a structure to realize that milling cutter.

Further, the both ends of dwang 6 all are equipped with the fillet, and is concrete, and the fillet at dwang 6 top prevents that dwang 6 from causing the fish tail to carousel 4 and milling cutter 3, protects milling cutter 3 and carousel 4.

Further, pivot 9 is with dwang 6 equipartition, and is concrete, when milling cutter anchor clamps 2 rotate, carousel 4 forms centrifugal force, and pivot 9 is with dwang 6 equipartition, and carousel 4's centrifugal force is overcome to carousel 4's gravity, and dwang 6 can not contact milling cutter 3's top, makes things convenient for milling cutter 3's use more.

Further, the both sides of spout 7 are the arc surface, and is concrete, and when guide post 8 slided in spout 7, when the both sides of spout 7 were the arc surface, the tip of guide post 8 more conveniently laminated with the arc surface, and increase guide post 8 moves to the stability of spout 7 arc surface.

Further, be equipped with torsion spring 10 between dwang 6 and the pivot 9, it is concrete, when dwang 6 does not use, torsion spring 10 keeps dwang 6 state that the outer end faces down, prevents that dwang 6 from knocking milling cutter 3's top at milling cutter 3 during operation, stabilizes the state of dwang 6, makes things convenient for milling cutter 3's normal use.

Furthermore, the surface of the rotary table 4 is carved with anti-skidding lines, specifically, the anti-skidding lines on the surface of the rotary table 4 increase the friction force between the hand and the surface of the rotary table 4, and the operation of the rotary table 4 is more convenient.

To sum up, finish at milling cutter 3 centre gripping back, strike milling cutter 3 through dwang 6, milling cutter 3 receives vibrations, milling cutter 3 becomes complete vertical state, rotate anchor clamps again, further press from both sides tightly, milling cutter 3's centre gripping is more stable, make things convenient for milling cutter 3's use more, loosen milling cutter 3 back at milling cutter anchor clamps 2, the vibrations power that provides through dwang 6, knock out milling cutter 3, make things convenient for taking out of milling cutter 3 more, it is more convenient to use a structure to realize milling cutter 3's installation and take out, the practicality is stronger, the fillet at dwang 6 top prevents that dwang 6 from causing the fish tail to carousel 4 and milling cutter 3, protection milling cutter 3 and carousel 4.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
