Specific embodiment

In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below Conjunction is specifically illustrating, and the utility model is further described.

As shown in Figs. 1-5, core grinding device, including pedestal 1, the top of pedestal 1 are fixedly connected there are two fixed block 2, It is fixedly connected jointly between two fixed blocks 2 and spherical shell 3 of the top with opening, two outsides of spherical shell 3 offers respectively Transverse opening 4, the internal side wall of spherical shell 3 and bottom are fixedly connected to multiple grinding blocks 5, and the inside of spherical shell 3 is equipped with ball Core 7, the inside of core 7 are fixedly attached rotating bar 6, and the both ends of rotating bar 6 sequentially pass through core 7 and are fixedly connected by flange 13 There is Z-type connecting rod 12, transverse opening 4 and rotation of the other end of Z-type connecting rod 12 on spherical shell 3 are socketed with ball axis 9 are held, two cylinders 10 are fixedly connected in the one side wall of each fixed block 2, and two cylinders 10 are respectively positioned on the two of spherical shell 3 Side, two cylinders 10 on one of fixed block 2 are corresponding with another 2 upper cylinder 10 of fixed block, and one of fixed The telescopic end of the telescopic end of 2 upper cylinder 10 of block and another 2 upper cylinder 10 of fixed block is fixedly connected with lantern ring 11 jointly, each Ball bearing 9 in Z-type connecting rod 12 is fixedly attached in lantern ring 11.

The other end of Z-type connecting rod 12 is equipped with stud, and the both ends of stud are threaded with nut 8, ball Bearing 9 is socketed on stud, and one end of each nut 8 is tightly abutted against with ball bearing 9.

The shape of rotating bar 6 is U-shaped, and core 7 is socketed in the middle position of rotating bar 6.

Be located at each transverse opening 4 on multiple grinding blocks 5 be set in qually spaced in each transverse opening 4 surface and Underface.

Working principle:

A, core 7 is put into the inside of spherical shell 3 by the opening at 3 top of spherical shell first, and makes grinding in spherical shell 3 Abrading block 5 and the outer surface of core 7 offset；

B, it then will go to bar 6 respectively from the transverse opening on 3 one end of spherical shell, core 7 be socketed in rotating bar 6 On, it is pierced by followed by from the transverse opening 4 on the other end of spherical shell 3, the both ends of rotating bar 6 is then passed through into flange respectively again 13 connect Z-type connecting rods 12, and one nut 8 of first screw thread in each Z-type connecting rod 12 then covers upper ball bearing 9 again, and will rolling 9 sets of pearl bearing on lantern ring 11, then recycle another 8 screw thread of nut in Z-type connecting rod 12；

C, then start four cylinders 10, and two cylinders 10 on a wherein fixed block 2 are in elongation, another Two cylinders 10 on fixed block 2 are in contraction state, so that the movement of the lantern ring 11 on the every side of spherical shell 3 is driven, thus The movement of ball bearing 9, Z-type connecting rod 12, rotating bar 6 and core 7 is driven, and since ball bearing 9 is fixedly attached to lantern ring The rotation of ball energy band ejector half Z-type connecting rod 12 on 11, therefore on ball bearing 9, to drive the rotation of rotating bar 6, then The rotation of core 7 is driven, and the side due to core 7 is in contact with the grinding block 5 of 3 side wall of spherical shell and bottom, therefore can utilized 3 inner sidewall of spherical shell and the grinding block 5 of bottom grind the outer surface of core 7；

In addition step b can be repeated, goes to be connected with rotating bar 6 and lantern ring 11 using the Z-type connecting rod 12 of different size, mesh Be that the Z-type connecting rod 12 of different size can suitably adjust core 7 and grinding inside spherical shell 3 according to the size of core 7 The contact area of abrading block 5, so as to preferably complete the abrasive tasks of different size core 7；

Under adjusting of the different size of core 7 in different size Z-type connecting rod 12, it is not met by core 7 and spherical shape When grinding block 5 inside shell 3 is in contact, the scheme of use is that core 7 is socketed in rotating bar 6, the Z that 6 both ends of rotating bar use 12 length of type connecting rod is inconsistent, i.e. that end length and the connection of another Z-type that a Z-type connecting rod 12 is connect with rotating bar 6 Bar 12 and the connection length of rotating bar are inconsistent, but are also so that Z-type connecting rod 12 is connected with rotating bar 6 by flange 13, mesh Mainly the side of core 7 and the grinding block 5 of 3 interior side of spherical shell are come into full contact with, then ground, wait and be ground into After function, the other side for retelling core 7 is adequately contacted with the grinding block 5 of the 3 inside other side of spherical shell, is then ground Mill, until core 7 is all polished successfully.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry it should be appreciated that the present utility model is not limited to the above embodiments, do not depart from the spirit of the present invention and Under the premise of range, the utility model also has various changes and improvements, these changes and improvements both fall within claimed Within the scope of utility model.The protection scope of the present invention is defined by the appended claims and their equivalents.
