Description
Technical Field
The invention relates to the technical field of drill bits, in particular to an auxiliary tool for a hole reamer with a down lamp.
Background
The trompil size between the different model down lamps on the market has great difference in prior art, and the down lamp of different trompil sizes is because current trompil size diameter is different to some extent in the change process, thereby need carry out the secondary reaming, however secondary reamer bit usually with the fluted drill pin joint in reamer bit in the current market, the installation is loaded down with trivial details with the dismantlement process, and because various reasons at the reaming in-process, reamer bit does not follow former trompil position and bores into, thereby lead to secondary drilling position to deviate, lead to the secondary to do over again, seriously influence the installation effectiveness.
Disclosure of Invention
In order to solve the problems, the invention provides an auxiliary tool for the hole-opened reamer of the down lamp, which is simple and convenient in mounting and dismounting process and can accurately position the hole-opened position.
In order to achieve the purpose, the auxiliary tool for the hole-opened reamer of the down lamp mainly comprises a secondary reamer, a positioning limiting cover and a drill bit, wherein the secondary reamer is sleeved on one side, close to a drill rod, of the drill bit, the secondary reamer is arranged in a hollow column body, the side, facing the drill bit, of the secondary reamer is the left side, a secondary reaming drill bit is arranged on the left side of the column body of the secondary reamer in a surrounding mode, and a chip discharge groove is arranged on the right side of the secondary reaming drill bit in a surrounding mode; the drill bit in be close to one side cover of drill point establish the spacing lid in location, the spacing lid in location for the border be the step setting, the ladder towards drill bit drill point side in the spacing lid in location is first ladder, the ladder towards drill bit drill handle side is the second ladder, and first ladder excircle diameter is less than second ladder excircle diameter, spacing lid in location and secondary reamer between be provided with trapezoidal pressure spring. The secondary reamer is fixed on the drill bit in a matched mode through the structure, the drill bit is sleeved with the positioning limiting cover, meanwhile, the friction force of the first step card in the existing open hole is preliminarily positioned at the position of the secondary open hole through the positioning limiting cover arranged along the step, and the positioning limiting cover is fixed in the position of the primary open hole through the pressure of the trapezoidal spring arranged between the secondary reamer and the positioning limiting cover.
The further scheme is that the larger end of the excircle diameter of the trapezoidal pressure spring faces the positioning limiting cover, and the smaller end of the excircle diameter faces the secondary reamer. The structure enables the larger end of the excircle diameter of the trapezoid pressure spring to face the positioning limiting cover, the stress area between the positioning limiting cover and the trapezoid pressure spring is increased, and therefore the secondary hole opening position is further accurately positioned.
A plane bearing is arranged on one side, facing the secondary reamer, of the second step of the positioning limiting cover, the right side end of the trapezoidal pressure spring is connected with the inner bottom surface of the right side of the secondary reamer in a matched mode, the left side end of the trapezoidal pressure spring is connected with a tightening ring in the plane bearing in a matched mode, and a loosening ring in the plane bearing is adhered to the second step of the positioning limiting cover. The setting of this kind of structure is covered through the loose ring fixed setting in location with planar bearing, and the tightring cooperates with trapezoidal pressure spring, prevents that secondary reamer from driving the rotatory back of trapezoidal pressure spring, leads to the spacing lid of location to produce and rotates to make secondary trompil position take place to deflect.
The auxiliary tool for the hole-opened reamer of the down lamp is characterized in that a positioning limiting cover is sleeved between a drill bit and the secondary reamer to accurately position the position of a secondary hole, a trapezoidal pressure spring is arranged between the positioning limiting cover and the secondary reamer, the positioning limiting cover is prevented from sliding in the drilling process through the pressure of the trapezoidal pressure spring, so that the position deviation of a secondary drilling hole is prevented, the working efficiency is prevented from being influenced if the fixing effect of the positioning limiting cover is further enhanced, and a plane bearing can be additionally arranged between the positioning limiting cover and the trapezoidal pressure spring to prevent the position deviation of the secondary drilling hole.
