Embodiment 1
[0051] Such as figure 1 , 2 As shown, a boring die includes a base 1, a front plate 2, a front boring sleeve 3, and fastening screws 7.
[0052] Such as figure 1 , 3 As shown, a front plate 2 is arranged on the base 1, and at least two through holes are opened on the front plate 2, and a front boring sleeve 3 is arranged in the through holes.
[0053] Such as figure 1 , 2 As shown, the base 1 is a rectangular flat plate, and the base 1 is provided with a pad 11 to support the workpiece 4 to be bored. The pad 11 is in the shape of a cuboid, and it is fixed on the On the upper surface of the base 1, four pads 11 are provided, and the four pads 11 are respectively located at four corners of a virtual rectangle.
[0054] The workpiece 4 is not limited to a specific shape, the workpiece 4 with a blank hole is installed on the base 1, and the blank hole is aligned with the front boring sleeve 3 to realize the boring operation.
[0055] Such as Figure 1-3 As shown, the base ...
Embodiment 2
[0075] The difference between this embodiment and Embodiment 1 is:
[0076] Such as Figure 4-6 As shown, two front plates 2 are arranged in parallel, and the through holes on the two front plates 2 are coaxial, and at least one front boring sleeve 3 passes through the through holes on the two front plates 2 in sequence. In this embodiment , the three front boring sleeves 3 pass through the through holes on the two front plates 2, thereby providing stable support for the front boring sleeves 3.
Embodiment 3
[0078] The difference between this embodiment and embodiment two is:
[0079] Such as Figure 7-9 As shown, the base 1 is also provided with a rear plate 5, and a through hole is opened on the rear plate 5, and a rear boring sleeve 6 is arranged in the through hole, and the rear boring sleeve 6 is coaxial with the corresponding front boring sleeve 3.
[0080] Such as Figure 7-9 As shown, the rear plate 5 is a vertical cuboid block, and the rear plate 5 is installed on the upper left end of the base 1 through bolt connection or welding. In this embodiment, the rear plate 5 is provided with three through holes, three The through holes are respectively coaxial with the three through holes on the front plate 2 .
[0081] Such as Figure 7 , 8 As shown, in actual application, the boring bar 8 extends into the front boring sleeve 3 and the rear boring sleeve 6 sequentially from the right side to the left, and the front boring sleeve 3 and the rear boring sleeve 6 cooperate to p...

Abstract
The invention relates to the field of boring dies, in particular to a boring die and a method for boring holes by using the boring die. The boring die comprises a base, wherein a front plate is arranged on the base, at least two through holes are formed in the front plate, front boring sleeves are arranged in the through holes, the front boring sleeves are integrally cylindrical, and flanges are arranged outside one end of each of the front boring sleeves. The method comprises the steps of installing a boring die, installing a workpiece on the boring die, boring different holes in sequence, and detaching the workpiece and the boring die after boring is completed. The boring die has the advantages that before boring, the relative positions of all the through holes in the front plate are determined according to the positions of all the holes in the workpiece, it can be guaranteed that the positions of all the front boring sleeves correspond to all the holes in the workpiece, the positionprecision is high when boring is conducted through guiding of all the front boring sleeves, and meanwhile an operator does not need to calculate the size; and the requirement for workers is low, andthe boring efficiency is high.
Description
technical field [0001] The invention relates to the field of boring dies, in particular to a boring die and a boring method using the boring die. Background technique [0002] Boring refers to the further processing of forged, cast or drilled holes. Boring can expand the aperture, improve precision, reduce surface roughness, and can also better correct the deviation of the original hole axis. Boring is mostly carried out by boring machines, and more of them are carried out by horizontal boring machines. For example, the publication number is A kind of improved horizontal boring machine disclosed by the Chinese utility model patent of CN204565183U is exactly a comparatively typical horizontal boring machine structure, and it comprises bed, and front column and rear column are respectively arranged at the two ends of bed, and front column and rear There is also a workbench between the uprights; a main shaft and a cooling assembly are arranged on the front upright, and a rotat...
