The position of the pin hole to be drilled is measured by a tape measure, and the roller is slightly rotated to be rotated to the position of the pin hole to be drilled. And the hydraulic cylinder is dropped down, and the furnace rollers are supported by the support frames at the two ends again, so that the pin hole drilling operation can be carried out.
The guide rod capable of elastically stretching up and down has the functions of stabilizing the hydraulic cylinder to push the rotating wheel to move in the axial direction and preventing radial deviation. The guide rod can be a sleeve type telescopic rod (consisting of two sections of sleeves) or a spring.
Furthermore, the support frame is formed by welding channel steel.
Further, the roller is a furnace roller.
The utility model has the advantages as follows:
use the utility model discloses an auxiliary fixtures assists and carries out drilling operation to roller class product, through the cooperation of lift support rotary device and two support frames, can easily realize the rotational positioning in cotter hole, convenient to use, easy operation, the operating efficiency improves by a wide margin.

Detailed Description
The principles and features of the present invention are described below in conjunction with examples, which are set forth only to illustrate the present invention and are not intended to limit the scope of the present invention.
Example 1
An auxiliary tool for rotary indexing drilling of roller products comprises a lifting support rotating device and two support frames 2;
the lifting support rotating device comprises a base 3, a hydraulic cylinder 4, a rotating wheel support frame 5, a rotating wheel set and two guide rods 7; the hydraulic cylinder 4 is arranged on the base 3; the rotating wheel support frame 5 is arranged at the top of the hydraulic cylinder 4; the upper end of the rotating wheel supporting frame 5 is provided with two rotating wheel groups symmetrically to the hydraulic cylinder 4; the two sets of rotating wheel sets are arranged along the axial direction of the roller 1; each group of rotating wheel sets comprises two rotating wheels 6 which are horizontally arranged along the radial direction of the roller 1; the rotating shaft of the rotating wheel 6 is arranged along the axial direction of the roller 1; the guide rod 7 is vertically arranged between the base 3 and the rotating wheel support frame 5; the two guide rods 7 are symmetrically arranged on two sides of the hydraulic cylinder 4 along the axial direction of the roller 1; the guide rod 7 can elastically stretch and retract in the vertical direction.
The supporting frame 2 is formed by welding channel steel and comprises a V-shaped opening 2.1 arranged on the bottom bracket; the opening of the V-shaped port 2.1 is upward; the dimensions of the V-shaped opening 2.1 are matched to the radial dimensions of the roll 1, so that the roll 1 is supported in the V-shaped opening 2.1.
