SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to solve the technical problem of providing a drum type casing clamping frock, improve machining efficiency.

To achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a drum-shaped shell clamping tool, including leading to the axle, the both ends of leading to the axle are provided with the ring flange respectively, the ring flange passes through the bolt fastening on the leading to the axle, be provided with tolerance shaft section on the shaft section that the leading to the axle and the ring flange contact, so that better fastening the ring flange; when the clamping is carried out, the annular drum-shaped part is arranged on the through shaft from the upper end of the through shaft, and the annular drum-shaped part is clamped between the two flange plates.

The utility model discloses preferred technical scheme lies in, be provided with the edge on the tolerance shaft section lead to the incision of axial symmetry to better cyclic annular cydariform part clamping position of regulation.

The utility model discloses preferred technical scheme lies in, the ring flange be provided with incision complex bolt hole to play and utilize the bolt fastening the ring flange.

The utility model discloses preferred technical scheme lies in, the ring flange is provided with a plurality of tight holes of clamp, and is a plurality of on being close cyclic annular cydariform part's the terminal surface of ring flange is followed the tight hole of clamp sets up to further press from both sides tight cyclic annular cydariform part through the bolt.

The utility model discloses preferred technical scheme lies in, the ring flange is close cyclic annular cydariform part one end and is provided with circular recess to reduce area of contact, the pressure that further increases unit area presss from both sides tight work piece.

The utility model discloses preferred technical scheme lies in, the terminal surface that the ring flange is close cyclic annular cydariform part one end is provided with the burr, in order to increase frictional force between ring flange and the cyclic annular cydariform part.

The beneficial effects of the utility model are that:

through set up tolerance shaft segment and incision on leading to the axle for the ring flange can be better the cyclic annular cydariform file of fastening, is favorable to dodging the cutter simultaneously, lets the interference when processing reduce, can process the external diameter and two terminal surfaces of drum type part simultaneously, in order to improve machining efficiency.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in the figure, the embodiment provides a drum-shaped shell clamping tool, which comprises a through shaft 1, wherein flange plates 2 are respectively arranged at two ends of the through shaft 1, the flange plates 2 are fastened on the through shaft 1 through bolts, and tolerance shaft sections 11 are arranged on shaft sections, which are in contact with the flange plates 2, of the through shaft 1, so that the flange plates 2 can be fastened better; during clamping, the annular drum-shaped part is firstly arranged on the through shaft 1 from the upper end of the through shaft 1, and the annular drum-shaped part is clamped between the two flange plates 2. Through setting up two tolerance shaft segments 11, lead to the one-time abrasive machining shaping of tolerance size at axle 1 both ends, both ends ring flange 2 links to epaxially with the screw, so alright with simultaneous processing external diameter and two terminal surfaces.

In order to fasten the flange 2 to the through shaft 1 by means of bolts, the tolerance shaft section 11 is preferably provided with notches 12 which are symmetrical along the axis of the through shaft 1, and the clamping position of the annular drum-shaped part is adjusted.

Preferably, the flange 2 is provided with bolt holes 21 that fit into the cutouts 12 to function to fix the flange 2 with bolts.

Preferably, a plurality of clamping holes 22 are formed in the end face, close to the annular drum-shaped part, of the flange plate 2, the clamping holes 22 are formed in the circumferential direction of the end face of the flange plate 2 so as to further clamp the annular drum-shaped part through bolts, a circular groove 23 is formed in one end, close to the annular drum-shaped part, of the flange plate 2, and a convex pattern is formed in the end face, close to one end of the annular drum-shaped part, of the flange plate 2 so as to increase friction between the flange plate 2 and the annular drum-shaped part. The circular groove 23 is arranged, so that the contact area of the flange plate 2 and the workpiece is reduced, the pressure per unit area is larger, and the workpiece can be further clamped.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
