Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
As shown in fig. 1-2, the reamer for high-precision reaming provided by the utility model comprises a handle part 1, a blade tooth part 2 arranged at one end of the handle part 1, and a force application ring 3, wherein a plurality of grooves 4 are annularly arranged on the outer peripheral surface of the other end of the handle part 1, a plurality of balls which can be respectively matched with each groove 4 in a sliding manner are rotatably connected to the inner annular surface of the force application ring 3, and a plurality of force application hand shafts 5 are fixedly connected to the outer annular surface of the force application ring 3.
In an alternative embodiment, a fixed ring strip 6 is fixedly connected to one side of the front end face of the force application ring 3, the fixed ring strip 6 is movably connected with one end of a connecting shaft 7 in a penetrating mode, and a movable ring strip 8 is fixedly connected to the other end of the connecting shaft 7.
In an optional embodiment, the middle part of the inner annular surface of the movable ring 8 is fixedly connected with a limit post 9, and the groove wall of the channel 4 is provided with a limit post groove 10 matched with the end part of the limit post 9.
In an alternative embodiment, a spring 11 is movably sleeved outside the connecting shaft 7 between the fixed ring strip 6 and the movable ring strip 8, one end of the spring 11 is fixedly connected with the outer annular surface of the movable ring strip 8, and the other end of the spring 11 is fixedly connected with the inner annular surface of the fixed ring strip 6.
In an alternative embodiment, a release preventing piece 12 is fixedly connected to one end of the connecting shaft 7 close to the fixing ring strip 6.
The working principle is as follows: in the embodiment, the reamer is easier to hold during manual operation by adding the force application ring 3 on the handle part 1, so that the reamer can rotate by simple and effective force application, the difficulty of the manual operation is simplified, specifically, the force application ring 3 slides to the position shown in the figure along the channel 4 from the end part of the handle part 1, the ball on the inner annular surface of the force application ring 3 can axially slide but cannot radially rotate with the channel 4 at the corresponding position, so that the reamer can be driven to rotate together when the force application hand shaft 5 is held to rotate the force application ring 3, the movable annular strip 8 leans against the handle 1 through the elastic thrust of the spring 11, and the limit column 9 on the inner annular surface of the movable annular strip 8 is clamped into the limit column groove 10, so as to limit the axial sliding of the balls in the grooves 4 and avoid the self-separation of the force applying ring 3 from the handle part 1; the application of force ring 3 in this scheme can be pulled apart from handle portion 1 according to actual need, can not influence the erection joint between reamer and the drilling machine, when dismantling, promotes activity ring 8 to the direction of fixed ring 6, makes spacing post 9 break away from in order to resume the axial slip of ball in channel 4 from spacing post groove 10, then can slide from handle portion 1 along channel 4 with applying force ring 3 and demolish.
