The device comprises a cylinder, wherein the outer diameter of the cylinder is slightly smaller than the aperture of a part, a conical surface is processed on the upper end surface of the cylinder, and the angle between the conical surface and the axis of the cylinder is consistent with the angle of an inclined hole of the part; after rotating, the part is clamped on a machine tool workbench, and the included angle between the central axis of the rotated part and the horizontal plane is consistent with the angle of the inclined hole of the part; the cylinder is mounted in the part by bolts.
Description
Technical Field
The utility model belongs to the drilling field, specificly relate to a device of drilling downthehole wall inclined hole.
Background
The inclined hole angle a between the inner side wall of the hole and the horizontal plane is not easy to process, and the inclined hole can be processed in an electric processing mode generally, but the electric processing has certain weaknesses, such as: because the electrode discharge corrosion processing is adopted, the processing time is long; the electricity is easy to be lost; the processing cost is relatively high; parts need to be immersed in oil during electric machining, and are complex to clean; environmental pollution, etc. If adopt drilling processing, the process time is short, and is with low costs, nevertheless because of the drill bit has great angle a with by the processing part surface, the tool bit can skid the skew position, causes the hole of processing partially or can't process, so downthehole lateral wall inclined hole also can not adopt the direct drilling of drilling machine. Therefore, a device capable of drilling the inclined hole on the inner side wall of the hole needs to be designed, so that the drilling angle between the drill bit and the part is 90 degrees, and drilling is realized.
Disclosure of Invention
In order to solve the problem that downthehole lateral wall inclined hole can not adopt the direct drilling of drilling machine, the utility model provides a device of drilling downthehole lateral wall inclined hole, its is with low costs, and the structure is succinct, can realize the drilling processing of downthehole lateral wall inclined hole.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model provides a device of drilling downthehole wall inclined hole which characterized in that: the device comprises a cylinder, wherein the outer diameter of the cylinder is slightly smaller than the aperture of a part, a conical surface is processed on the upper end surface of the cylinder, and the angle between the conical surface and the axis of the cylinder is consistent with the angle of an inclined hole of the part; the part is clamped on a machine tool workbench after being rotated, and the included angle between the central axis of the rotated part and the horizontal plane is consistent with the angle of the inclined hole of the part; the cylinder is mounted in the part by bolts.
It is further characterized in that:
the center of the cylinder is provided with a first through hole and a second through hole from top to bottom, the aperture of the first through hole is larger than that of the second through hole, the bolt can penetrate through the first through hole and the second through hole and be screwed into the bottom of the part, the cylinder is installed in the part, and the head of the bolt is pressed in the first through hole.
