Description

Toolroom machine integrated structure

Technical field

The present invention relates to a kind of automatic tool changers；More particularly to a kind of knot between motor and main shaft suitable for toolroom machine Close structure.

Background technology

Press, the integrated structure between the motor and main shaft of toolroom machine is very important, whether combination or combine after it is steady Whether the soundness power transmission that all concerns is smooth.By taking drilling-tapping center machine as an example, automatic tool changer include tool magazine with Transmission speed reducer, wherein tool magazine are included in rotatable cutterhead periphery and are provided with multiple knife bars, and cutter is combined on knife bar；Cutterhead one Side connects transmission speed reducer by integrated structure, and starting transmission speed reducer can rotate to carry out tool changing operation with movable knife disc.

The known structure for being combined cutterhead with transmission speed reducer is as shown in Figure 1, on a conjoint disk 1a of transmission speed reducer 1 Multiple screw hole 1b for being arranged in round are drilled with, in the perforation 2a that multiple corresponding screw hole 1b are drilled on cutterhead 2, utilize bolt 3 Perforation 2a is worn to lock in screw hole 1b and cutterhead 2 can be combined with transmission speed reducer 1 after screwing again.Aforementioned combination Though may achieve assembling purpose, for ensure the stability with reference to after and screw all bolts 3 when, it is related so that conjoint disk 1a Be close to cutterhead 2 while, in other words, conjoint disk 1a and cutterhead 2 are the relationships being in direct contact, and this situation is easily made It is influencing each other to each other into the vibration or other kinetic energy generated during mechanism start, non-one appropriate situation.

Fig. 2 show another structure for becoming known for combining cutterhead and transmission speed reducer, in a master of transmission speed reducer 4 Be coupled between axis 4a and cutterhead 5 using the shaft coupling 6 of high rigidity, i.e., shaft coupling 6 for loop shaped structure and be sheathed on main shaft 4a with Between cutterhead 5, and snugly reach gearing purpose.However, the shaft coupling 6 of loop shaped structure and the big cutterhead 5 of load-carrying, During the Fixed-point Motion of A of tool changing operation, hiding the defects of generating slip due to effect of inertia.Therefore, using shaft coupling 6 also Non-appropriate selection.

Invention content

In view of this, it is steady with good combination it is a primary object of the present invention to provide a kind of toolroom machine integrated structure Soundness, and influence to each other can be reduced.

For edge to reach above-mentioned purpose, the present invention provides a kind of toolroom machine integrated structure, a cutterhead and a transmission to be subtracted The conjoint disk of fast machine combines；Wherein multiple first perforation are distributed in the periphery of a mandrel in the cutterhead；The conjoint disk has an axis Hole is penetrated for the mandrel, and multiple second perforation are distributed in the periphery of axis hole in the conjoint disk；Separately there are multiple engaging members that there is phase Different both ends are respectively penetrated in corresponding first perforation and second perforation, and the engaging member has radial load to act on this In first perforation and biperforate hole wall.

In one embodiment, include multiple first bushings fill in respectively this first perforation in and multiple second bushing plugs Enter in respectively second perforation, the different both ends of the engaging member are inserted into respectively in corresponding first bushing and the second bushing.

In one embodiment, which has one first face, which has one second face in face of first face, and should First face is separated by a spacing with second face.

In one embodiment, which has one first block face in one first depth, in second bushing Wall has one second block face in one second depth, and the different both ends of the engaging member are butted on first block face and the second gear respectively Face, and the length of the engaging member is more than the summation of first depth and second depth.

In one embodiment, the engaging member is with rigid cylinder, and barrel axially offers a profile groove.

In one embodiment, the cutterhead hardness be less than the conjoint disk hardness, the conjoint disk hardness be less than first bushing or The hardness of second bushing.

Effect of the invention is that cutterhead is respectively penetrated with conjoint disk by the both ends of multiple engaging members can avoid sliding It generates, and to possess appropriate gap between cutterhead and conjoint disk to reduce gearing influence property that may be present to each other.
