Description
Technical Field
The utility model relates to a cutter technical field, concretely relates to special smart reamer cutter of aluminum alloy.
Background
The special precision reamer for the aluminum alloy is a special cutter for precisely machining the multistage aluminum alloy circular holes with small tolerance and high requirement on coaxiality among the circular holes.
In the process of implementing the present invention, the inventor finds that:
the special tool is large in machining size and is a multi-stage hole, so that the special tool needs a larger appearance and a heavier volume for manufacturing the tool, the tool is arranged on a horizontal machining center for use, the gravity direction of the mounted tool is perpendicular to the tensioning direction of the blind rivet, therefore, when the tool rotates at a high speed, the tool always bears a vertically downward gravity, and the tool is tensioned in the horizontal direction of the blind rivet, so that the following two conditions occur:
firstly, the rotating speed of the cutter is improved, the inner hole finish degree reaches the standard, but the vibration lines are caused by large swing error under the action of gravity; secondly, the rotating speed of the cutter is reduced, the inner hole vibration lines disappear, but the cutter cannot ensure the surface smoothness of the inner hole due to insufficient linear speed, and the service life of the cutter is also reduced.
Disclosure of Invention
In order to guarantee the smooth finish of product, avoid appearing the shake line because of the cutter rotational speed is high, prolong the life of cutter simultaneously, the utility model provides a special smart reamer cutter of aluminum alloy.
The invention conception is as follows: the above problems are caused by the fact that the tool is used in a horizontal machining center and the direction of gravity is perpendicular to the direction of tension of the blind rivet. The utility model discloses consider through carrying out the lightweight design to the cutter, structurally make corresponding improvement under the prerequisite of guaranteeing the function.
Therefore, the technical scheme of the utility model is that: the utility model provides a special smart reamer cutter of aluminum alloy, is including the blind rivet, handle of a knife and the cutter body that connect gradually, through threaded connection between blind rivet and the handle of a knife, through the screw connection between cutter body and the handle of a knife, cutter body periphery equipartition has axially extended's blade installation department, is fixed with spaced PCD blade through copper welding on the blade installation department, be equipped with along the center pin between blind rivet, handle of a knife and the cutter body and be linked together cutting fluid passageway, its characterized in that:
the inside of the cutter body is of a hollow structure, a hole cavity communicated with the middle hollow structure is formed between every two adjacent blade mounting parts on the outer peripheral surface of the cutter body, and a reinforcing rib for connecting the two adjacent blade mounting parts is arranged in the hole cavity;
the cutting fluid channel in the cutter body extends to each blade mounting part along the inlet of the cutter body in a casting mode, and then extends to each blade from the blade mounting part in an axial mode and then extends to each blade in a casting mode.
Preferably, the reinforcing ribs are of an arc structure which is arched outwards, and the height of the reinforcing ribs from the central shaft is smaller than the height of the cutting edges of the blades from the central shaft.
Has the advantages that: compared with the prior art, the utility model has the advantages that the weight of the cutter body is reduced from 28KG to 18KG by the lightweight design on the premise of ensuring the performance and the processing quality of the cutter body, and the influence of gravity is reduced; the highest rotating speed of the cutter before improvement can only be increased to 190 revolutions per minute, the feeding can only be increased to 60mm per minute, the cutter is damaged, and the efficiency is low; the maximum rotating speed of the improved cutter can be increased to 800 rpm, and the feeding speed can be increased to 200 mm/min; the area of the PCD blade is reduced compared with the original area, and the heat dissipation speed of the cutter can be effectively accelerated.
Meanwhile, the reinforcing ribs are arranged into an arc-shaped structure which is arched outwards, the dynamic balance is good, the rigidity is good, the precision can be effectively guaranteed, and the size is limited to avoid interference.
