In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, 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 utility model and are not intended to limit the utility model.
The present invention provides a large diameter center hole adapter.
Referring to fig. 1 to 3 together, a large-diameter center hole conversion head according to a first embodiment of the present invention includes a connection body 10, a threaded post 20 and a torsion member 30, wherein a center hole 40 is formed at one side of the connection body 10, and a maximum diameter of the center hole 40 is smaller than a center screw hole 50 of a roll; the threaded column 20 is connected with the other side of the connecting body 10 and is provided with an external thread matched with a central screw hole 50 of a roller; a torque element 30 is connected to the connecting body 10 for tightening the threaded stud 20 onto the central threaded bore 50 of the roll.
Compared with the prior art, the major diameter centre bore change-over head that this embodiment provided, when using, through the torsion member 30 with screw thread post 20 screw up in the central screw 50 of roll, make centre bore 40 on the connector 10 outwards for it can push up on centre bore 40 top, and then realizes the abrasive machining to these great specification rolls, overall structure is simple and practical, and the cost is lower, practical convenient.
Further, referring to fig. 1 to fig. 3, a first embodiment of the present invention further provides the following:
the torsion member 30 is one or more of an outer hexagonal structure, an inner hexagonal structure, a lever hole structure, and a socket wrench connection structure provided on the connecting body 10.
The torsion member 30 includes a torsion wrench, one end of which is fixedly connected to the connecting body 10, and the other end of which extends to the outside of the connecting body 10.
A through hole 11 is formed at one end of the torsion wrench, which extends to the outer part of the connecting body 10, so that tools such as hooks can be hung to tighten the threaded column 20; the two sides of the twisting wrench are provided with parallel surfaces which are parallel to each other, so that a pliers or a wrench can clamp the twisting wrench conveniently.
The outer diameter of the connecting body 10 is larger than the inner diameter of the central screw hole 50 of the roller, so that the connecting body 10 can be in pull fit with the external thread of the threaded column 20 and firmly abut against the outside of the central screw hole 50 of the roller to form stable connection.
The part of connector 10 and threaded column 20 connection is frustum column structure, and the top of frustum column structure is connected with threaded column 20, and the outside cover of frustum column structure is equipped with mild steel gasket 12, and the internal surface of mild steel gasket 12 cooperates with the surface of frustum column structure. Such a configuration facilitates a more secure seating of connecting body 10 outside central threaded bore 50 of the roll due to the relatively significant deformation of mild steel shim 12 upon compression, and prevents slippage of threaded post 20 when threaded post 20 is subjected to excessive torque and slides along the outer surface of the frustoconical structure.
Further, referring to fig. 4 to fig. 6, a first embodiment of the present invention further provides the following embodiments:

The through groove 45 can play a role in skid resistance and exhaust and oil discharge, and the phenomenon that the top of the top tip is not tight enough after impurities such as oil, dirt and the like enter the center hole is avoided.
The central bore 40 further includes a mild steel pad layer 46, the mild steel pad layer 46 being laid on the inner wall of the central bore 40. Because the mild steel cushion layer 46 can take place relatively obvious deformation after the pressurized, moreover with recess 45 cooperation back, can make the apex can better laminate, push up tightly better.
The included angle between two generatrices on the longitudinal section of the inner hole section 41 passing through the axis of the central hole 40 is 0, the included angle between two generatrices on the longitudinal section of the first taper hole section 42 passing through the axis of the central hole 40 is 60 degrees, the included angle between two generatrices on the longitudinal section of the second taper hole section 43 passing through the axis of the central hole 40 is 75 degrees to 50 degrees, and the included angle between two generatrices on the longitudinal section of the third taper hole section 44 passing through the axis of the central hole 40 is 120 degrees.
