Utility model content
In order to solve the problem that grinding rod in prior art is easily deformed, this utility model provides a kind of and certainly finds grinding rod accurately for what grind deep hole.
A kind of certainly find grinding rod accurately for what grind deep hole, including supporting rod, milling bar and connecting rod.The upper end of described milling bar is provided with two symmetrical connecting plates, and each connecting plate is provided with the first through hole, and the centre position of two connecting plates is stretched in the lower end of described supporting rod.The lower end of supporting rod is provided with the second through hole, and described connecting rod passes the first through hole and the second through hole.Being provided with spiral liquid bath in described ground section, described liquid bath extends to bottom from the top of ground section.
Preferably, described first through hole is screw, and connecting rod is connected by screw thread with the first through hole；The internal diameter of the second through hole is more than connecting rod diameter, connecting rod traverse the second through hole.Threadeding between connecting rod with milling bar, connecting rod is flexibly connected with supporting rod, and the relative supporting rod of milling bar can move, and milling bar is under gravity, it is possible to automatically adjust the angle with horizontal plane, makes each position of deep hole that need to grind grind uniformly.
Preferably, described second through hole is screw, and connecting rod is connected by screw thread with the second through hole；The internal diameter of the first through hole is more than connecting rod diameter, connecting rod traverse the first through hole.Connecting rod and supporting rod are threaded connection, and connecting rod is flexibly connected with milling bar, and the relative supporting rod of milling bar can move, and milling bar is under gravity, it is possible to automatically adjust the angle with horizontal plane, make each position of deep hole that need to grind grind uniformly.
Preferably, the internal diameter of described first through hole and the second through hole is all higher than the diameter of connecting rod, and the two ends of described connecting rod are threaded nut.Connecting rod is flexibly connected with milling bar and supporting rod respectively, and the relative supporting rod of milling bar can move, and milling bar is under gravity, it is possible to automatically adjust the angle with horizontal plane, makes each position of deep hole that need to grind grind uniformly.
Preferably, the degree of depth of liquid bath is gradually reduced from the top of ground section to bottom.The lapping liquid that bottom is piled up is more, and in order to avoid the bottom of deep hole is ground many, the degree of depth of liquid bath is gradually reduced from the top of ground section to bottom.
This utility model compared with prior art, has the advantages that
Above-mentioned a kind of certainly finding grinding rod accurately for what grind deep hole, milling bar is movably connected on supporting rod by connecting rod, and connecting rod can be movable in the first through hole and the second through hole, or can be movable in the first through hole or the second through hole.In use, milling bar is under gravity, it is possible to automatically adjust the angle with horizontal plane, makes each position of deep hole that need to grind grind uniformly.Being additionally provided with spiral liquid bath on milling bar, lapping liquid can flow in liquid bath, makes milling bar each position lapping liquid be uniformly distributed.

Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 4, this utility model is described in detail.
A kind of certainly finding grinding rod accurately for what grind deep hole, including supporting rod 1, milling bar 22 and connecting rod 3, the upper end of described milling bar 22 is provided with two symmetrical connecting plates 21, and each connecting plate 21 is provided with the first through hole 211.The centre position of two connecting plates 21 is stretched in the lower end of described supporting rod 1, and the lower end of supporting rod 1 is provided with the second through hole 11, described connecting rod 3 traverse the first through hole 211 and the second through hole 11.Being provided with spiral liquid bath 221 in described ground section, described liquid bath 221 extends to bottom from the top of ground section, and the degree of depth of liquid bath 221 is gradually reduced from top to bottom.
As further improvement of the utility model, described first through hole 211 and the second through hole 11 have at least the internal diameter of bigger than the internal diameter of connecting rod 3.Wherein, when the internal diameter of only one of which through hole is bigger than the internal diameter of connecting rod 3, another through hole can be threaded connection with connecting rod 3.When the internal diameter of the first through hole 211 and the second through hole 11 is all higher than the diameter of connecting rod 3, the two ends of described connecting rod 3 are threaded nut.Milling bar 22 and supporting rod 1 are flexibly connected by connecting rod 3, and the relative supporting rod 1 of milling bar 22 can move, and milling bar 22 is under gravity, it is possible to automatically adjust the angle with horizontal plane, make each position of deep hole that need to grind grind uniformly.
