Description
Technical Field
The utility model relates to a metal cutting processingequipment, specifically speaking are high-efficient turning device of wheel hub.
Background
Turning tools are one of the most widely used metal cutting tools. The machine tool is mainly used for machining excircles, inner holes, end faces, threads, turning grooves and the like on various lathes. The turning tool has remarkable working characteristics: the cutter is a single-edge cutter, and in the cutting process, the posture of the cutter is fixed, only translation can be carried out, and rotation cannot be carried out.
The outer circle part and the inner cavity of the aluminum alloy hub are turned, and figure 1 is a turning schematic diagram of the aluminum alloy hub. The turning tool is driven by the tool turret to move according to the track of A1 → A2.
The factor directly related to the cutting efficiency is the cutting speed, which is generally expressed by the formula V1=ω1·R1Is shown in the formula, wherein V1Indicates the cutting speed (linear velocity), omega, of the tip of the turning tool1Indicating the rotational speed (angular velocity) of the hub, R1The cutting radius of the hub (the radius of the portion where the cutting edge is located) is shown.
In fact, in the conventional turning process, the insert is not rotated and is single-edged. If the turning tool blade rotates at a high speed while the aluminum alloy hub rotates, the cutting speed is greatly improved.
The extension of the electric spindle provides technical feasibility for this purpose. The electric spindle is a new technology which integrates a working spindle and a motor into a whole and appears in the field of numerical control machines. The electric main shaft is a set of components, it includes electric main shaft itself and its accessories, and the transmission structure form of said main shaft motor and machine tool main shaft "combining two into one" can make the main shaft component be relatively independent from the transmission system and whole structure of machine tool, so that it can be made into "main shaft unit", commonly called "electric main shaft", and its characteristics are high rotating speed, high accuracy and low noise.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high-efficient turning device of hub.
In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a high-efficient turning device of wheel hub, includes electric main shaft, blade disc, gland, screw, its characterized in that: the cutter head is installed at the head of the electric main shaft, and is fastened by screws after being compressed by a gland, the cutter head is preferably circular, square can be selected in certain environments, the center of the cutter head is hollow and is provided with a key groove, a plurality of cutting edges are uniformly distributed outside the cutter head, and the cutting edges can participate in turning.
Compared with the prior art, high-efficient turning device of wheel hub have following advantage: in the turning process, the aluminum alloy hub rotates at a high speed, the cutter head is driven by the electric spindle to rotate at a high speed, and the actual cutting speed is V2=ω1·R1+ω2·R2In the formula V2Indicates the cutting speed (linear velocity), omega, of the tip of the turning tool1Indicating the rotational speed (angular velocity) of the hub, R1Indicates the cutting radius of the hub (radius of the portion where the blade tip is located), omega2Indicating the rotational speed (angular velocity), R, of the cutter head2The radius of the nose of the cutter head is shown. And the original cutting speed V1Compared, the utility model discloses cutting speed V2The production efficiency is greatly improved; in addition, the loss of the turning tool is distributed to each cutting edge by the design of the plurality of cutting edges, so that the loss of the turning tool is reduced.
