Problems solved by technology

The traditional deep hole drilling jig fixes one end of the drill bit and drills the other end. Because it is a deep hole drill, the drill bit can still rotate along the original direction of the drill bit near the fixed end, but the drill bit far away from the fixed end is not drilling. When it is easy to deviate, this will cause the deep hole of the workpiece to be processed does not meet the standard. Therefore, a deep hole drilling fixture is needed to limit the drill bit and prevent the drill bit from wandering when drilling.

Embodiment Construction

[0022] Such as Figure 1-2 As shown, a deep hole drilling jig includes a box body 4, a bushing seat, and a base 1. The box body 4 is provided with a deep hole 42, and a storage slot 44 is opened in the box body 4, and the workpiece to be processed is arranged in the storage slot 44. Inside, the position of the workpiece to be drilled is set on the central axis of the deep hole 42 . The workpiece to be processed is arranged in the box body 4, and the deep holes set in the box body have a guiding effect on the drilling.

[0023] The base 1 is an L-shaped structure, the box body 4 is arranged on the horizontal part 101 of the base, and the bush seat is arranged on the inner side of the vertical part 102 of the base.

[0024] A bushing hole is arranged on the bushing seat, and the bushing seat is arranged between the fixed end of the drill bit and the box body, and the central axis of the bushing hole coincides with the central axis of the deep hole on the box body. The bush sea...

Abstract

The invention discloses a deep hole drill fixture. The deep hole drill fixture comprises a box body and a bushing seat, the box body is provided with a deep hole, a storage tank is arranged in the box, a machined workpiece is arranged in the storage tank, and the position, needing to the drilled, of the machined workpiece is arranged on the center axis of the deep hole. The bushing seat is provided with bushing holes and arranged between the fixed end of a drill bit and the box body. The center axes of the bushing holes coincide with the center axis of the deep hole in the box body. The fixture has the advantages that in the deep hole drilling process, a guiding effect is achieved on the drill bit and a reamer, and the situation that the percent of pass of the machined workpiece is influenced due to the fact that the drill bit or the reamer deflects in the machining process of the machined workpiece is prevented.

Description

technical field [0001] The invention relates to the field of jigs, in particular to a deep hole drilling jig. Background technique [0002] The deep-hole diamond adopts a special deep-hole drill bit, and the drill bit moves in a straight line. The traditional deep hole drilling jig fixes one end of the drill bit, and the other end drills the hole. Because it is a deep hole drill, the drill bit can still rotate along the original direction of the drill bit near the fixed end, but the drill bit far away from the fixed end is not drilling. It is easy to deviate when it is time, which causes the deep hole of the workpiece to be processed does not meet the standard. Therefore, a deep hole drilling fixture is needed to limit the drill bit and prevent the drill bit from wandering when drilling. Contents of the invention [0003] The technical problem to be solved by the present invention is that the drill bit of the deep hole drill is easy to deviate away from the fixed end, so ...
