Specific embodiments
[0025] The following will clearly and completely describe the technical solutions of the present utility model in combination with specific embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0026] The present utility model provides an anti-collision device for a machine tool processing head, as Figures 1 to 4 shown, including a cylindrical first fixed cylinder 1, a second fixed cylinder 2 arranged inside the first fixed cylinder 1, a connecting rod 3 arranged in the second fixed cylinder 2, and a processing head body 4 arranged at the bottom of the connecting rod 3. A protection member 5 for protecting the processing head body 4 is slidably arranged between the first fixed cylinder 1 and the second fixed cylinder, and there is a set distance between the bottom end of the protection member 5 and the bottom end of the processing head body 4.
[0027] Further, the protective member 5 includes a first protective shell 5a slidably disposed on the inner wall of the first fixed cylinder 1 in the vertical direction and a funnel-shaped second protective shell 5b disposed at the bottom of the first protective shell 5a. The bottom end of the second protective shell 5b can be movably attached to the outer wall of the processing head body 4.
[0028] Further, a circular first limiting block 6 is provided at the top end of the first protective shell 5a, and a circular second limiting block 7 matched with the first limiting block 6 is provided at the bottom of the first fixed cylinder 1.
[0029] Further, a connecting cylinder 8 threadedly connected to the inner wall of the first fixed cylinder 1 is provided at the bottom of the first fixed cylinder 1, and the second limiting block 7 is located at the top end of the connecting cylinder 8.
[0030] Further, a plurality of first elastic shock-absorbing rings 9 are uniformly provided on the outer wall of the connecting rod 3, and a plurality of first shock-absorbing grooves 10 corresponding to the first elastic shock-absorbing rings 9 one by one are formed in the second fixed cylinder 2.
[0031] Further, a first elastic shock-absorbing layer 11 is provided between the top of the connecting rod 3 and the second fixed cylinder 2.
[0032] Further, a second elastic shock-absorbing layer 12 is provided between the top of the second fixed cylinder 2 and the first fixed cylinder 1.
[0033] Further, the horizontal plane where the bottom end of the connecting rod 3 is located is lower than the horizontal plane where the bottom end of the second fixed cylinder 2 is located. A limiting hole 13 is formed at the bottom end of the second fixed cylinder 2, and a buffer washer 14 matched with the limiting hole 13 is provided on the outer wall of the connecting rod 3.
[0034] Further, a plurality of second elastic shock-absorbing rings 15 are uniformly provided on the outer wall of the second fixed cylinder 2, and a plurality of second shock-absorbing grooves 16 corresponding to the second elastic shock-absorbing rings 15 one by one are formed in the first fixed cylinder 1.

[0036] When the processing head body 4 is ready for processing, the first limiting block 6 at the top of the first protective shell 5a abuts against the second limiting block 7. At this time, there is a certain distance between the bottom end of the second protective shell 5b and the bottom end of the processing head body 4, ensuring that normal processing can be carried out when the processing head body 4 moves downward for processing. At the same time, the first protective shell 5a and the second protective shell 5b protect the side surface of the processing head body 4.

The operation is simple and convenient for replacing the protective part 5.
[0038] By providing the first elastic shock-absorbing ring 9, the second elastic shock-absorbing ring 15, the buffer gasket 14, etc., when the processing head body 4 receives a side collision, in addition to the blocking of the protective part 5, the elastic deformation of the first elastic shock-absorbing ring 9, the second elastic shock-absorbing ring 15 and the buffer gasket 14 can also buffer the impact force received by the processing head body 4, thereby further avoiding damage to the processing head body 4 and achieving the purpose of reducing production costs.
[0039] By providing the first elastic shock-absorbing layer 11 and the second elastic shock-absorbing layer 12, when the processing head body 4 moves downward for processing, the elastic deformation of the first elastic shock-absorbing layer 11 and the second elastic shock-absorbing layer 12 buffers the vibration received by the processing head body 4, prolongs the service life of the processing head body 4, and achieves the purpose of reducing production costs.
[0040] By providing the rotating block 17, it is convenient to rotate the connecting cylinder 8, making the replacement operation of the protective part 5 more convenient.
