Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the utility model provides a floating cutter bar 4 for processing an idle gear shaft, which comprises an installation rod 1 installed on a machine tool, after the machine tool is started, the machine tool drives the installation rod 1 to rotate at a high speed, a cutter bar 4 which can only swing around the end and cannot rotate around a vertical line is installed at one end of the installation rod 1, and a cutter head 5 is installed on the cutter bar 4, so that after the machine tool is started, the cutter head 5 can smoothly rotate at a high speed and process the idle gear shaft under the driving of the installation rod 1, when in processing, if the central axis of a bottom hole does not coincide with the central axis of the cutter head 5, when the cutter head 5 rotates downwards at a high speed and enters into the bottom hole, the cutter head 5 can automatically swing around the installation rod 1 to adjust the position of the cutter head 5, until the central axis of the cutter head 5 coincides with the central axis of the bottom hole, thereby ensuring smooth processing of the bottom hole and no error is generated, the practicability is good.

The specific connection mode of the mounting rod 1 and the cutter bar 4 is as follows:

as shown in fig. 3, a movable ball 6 is fixedly mounted at one end of the cutter bar 4, the diameter of the movable ball 6 is larger than that of the cutter bar 4, the movable ball 6 is movably inserted into the mounting rod 1, as shown in fig. 5-8, a limiting groove 62 and a mounting hole 61 for tightly inserting one end of the cutter bar 4 into the limiting groove are formed in the movable ball 6, as shown in fig. 3 and 4, a limiting block for preventing the movable ball 6 from rotating around a vertical line is arranged in the limiting groove 62, that is, the cutter bar 4 is movably connected with the mounting rod 1 in a non-rotating manner through the movable ball 6, the cutter bar 4 can swing around the mounting rod 1 and cannot rotate around the vertical line, so that after the machine tool is started, the mounting rod 1 can drive the cutter bar 4 to rotate at a high speed to drive the cutter head 5 to drill the idler gear shaft.

As shown in fig. 1 and 3, an end cover 2 is detachably and fixedly mounted at one end of a mounting rod 1 through a bolt 3, a through hole 22 is formed in the end cover 2, a cutter bar 4 penetrates through the through hole 22, and the diameter of the cutter bar 4 is smaller than the aperture of the through hole 22, so that the end cover 2 can be movably sleeved on the cutter bar 4, and the cutter bar 4 can swing around the mounting rod 1 in the through hole 22;

in addition, the diameter of the movable ball 6 is larger than the diameter of the through hole 22, so that the movable ball 6 cannot slip out of the mounting bar 1;

the end cover 2 and the mounting rod 1 are both provided with hemispherical pits, as shown in fig. 3 and 9-12, the mounting rod 1 is provided with an upper hemispherical pit 11, the end cover 2 is provided with a lower hemispherical pit 21, the two hemispherical pits form a ball hole for accommodating the movable ball 6, and the ball diameter of the ball hole is equal to that of the movable ball 6.
