Detailed Description

The present invention will be further described with reference to the following description of the drawings.

As shown in fig. 1 to 5, a reamer with an adjustable reamer ring includes a reamer bar 100, a reamer ring 200, a positioning pin 300, a press ring 400 and a nut 500, wherein a cylindrical connecting rod 102 is disposed at a front end of the reamer bar 100, the reamer ring 200 is provided with an inner cone 202, the cylindrical connecting rod 102 penetrates through the inner cone 202, an upper end surface of the reamer bar 100 is attached to an upper end surface of the reamer ring 200, the press ring 400 is sleeved on the cylindrical connecting rod 102 through an inner hole 402, an outer cone 401 is disposed on the press ring 400, the outer cone 401 is located in the inner cone 202 of the reamer ring 200 and is attached thereto, the nut 500 is disposed at a tail end of the cylindrical connecting rod 102, a plurality of cutting edges 203 are welded on an annular surface of the reamer ring 200, at least two driving holes 101 are disposed on the upper end surface of the reamer bar 100, a plurality of clamping grooves 201 are disposed on the inner cone 202 of the reamer ring 200, and the positioning pin 300 is inserted into the driving holes 101 and connected to the clamping grooves 201 on the reamer ring.

In this technical scheme, 8~12 cutting edges 203 have been welded on the annular surface of reamer ring 200, offer the row that a plurality of and cutting edges 203 correspond on the reamer pole 100 and cut groove 103, all seted up cooling hole 104 in every row cuts the groove 103, seted up the internal thread on the nut 500 hole, the external screw thread has been seted up with the nut link to cylinder type connecting rod 102, nut groove 501 has been seted up on nut 500, nut groove 501 cooperatees with constant head tank 300.
