A cam plate is oscillatable relative to the head about the axis, and has elongated cam slots which are arranged in end to end spaced relation in a row extending circumferentially of the axis. The slots are connected by cam followers to the tool carriers, respectively. The slots are shaped so that, upon rotation of the cam plate relative to the head in one direction at a uniform rate, they first recede all of the carriers concurrently at the same rate of speed away from the axis part way toward their fully receded positions to produce a full depth taper cut, and then recede the carriers at increased rates, to run out and collapse positions. Beginning with the second slot in the series, each slot, during run-out, recedes its associated carrier at a greater rate than the rate of recession of the immediately preceding carrier. The die head and a coaxial pipe supporting chuck are relatively rotated about the axis while driven relatively toward and away from each other end-wise of the rotational axis. A cam maintains the recessions for taper cutting and die run-out to collapsed position in predetermined fixed relation to the relative advance of the head and pipe held in the chuck.，下面是Tool head with multiple tools and common oscillatable recede and collapse cam mechanism专利的具体信息内容。

权利要求

1. An apparatus for making tapered cuts on a workpiece, comprising: a cutter head including a body; a plurality of cutting tool carriers mounted on the body in spaced relation to each other circumferentially of a common axis and each for guided movement relative to the body toward and away from said axis; a cam member mounted on the body for rotation relative thereto about said axis; a plurality of cams on the cam member, one for each carrier, and drivingly connected to the carriers for driving the carriers concurrently generally radially in opposite directions relative to said axis to extended and collapsed positions, respectively; drive means to drive the cam member in said opposite directions, selectively; characterized in that: each cam has a carrier recede portion for receding its associated carrier at a predetermined rate relative to the rate of rotation of the cam member in one of said directions, and a carrier run-out portion for receding its associated carrier at a rate greater than said predetermined rate relative to said rate of rotation of the cam member in said one of said directions, and the recede portion leads the run-out portion in said one of said directions of rotation of the cam member.

2. The structure according to claim 1 and further including: a chuck; means supporting the body and chuck for rotation relative to each other about said common axis, and for lineal movement relative to each other along a path parallel to said axis in one direction from a starting position to a predetermined advanced position, and in the opposite direction from said advanced position to said starting position; power means for effecting said relative rotation and lineal movement concurrently in fixed relation to each other; said drive means including a carrier receding drive operative to rotate said cam member, in the one of its directions of rotation for receding the carriers, in predetermined fixed relation to said relative lineal movement of the body and chuck toward advance position during their relative rotation, to a predetermined rotated position; means to hold said cam member in its said predetermined rotated position beginning upon completion of the full recession of the carriers and continuing during return of the body and chuck lineally to their relative starting position, and to rotate said cam member in the one of its directions for extending the carriers to an oscillated starting position prior to the body and chuck being moved into said starting position; further characterized in that: said drive means includes a step cam element and a cam follower element, one of said elements being mounted on the cam member for rotation therewith, and the other of said elements being supported in a predetermined position along said lineal path; said step cam element being mounted for movement to a plurality of operating positions, and having a plurality of cam faces positionable for engagement with the follower, respectively, by movement of the step cam element to said operating positions, respectively, and operable, when engaged with the follower element, to impart different rates of rotation of the cam member relative to rate of travel of the body and chuck relatively toward each other; and power means for moving the step cam element to said operating positions, selectively.

3. An apparatus according to claim 1 wherein the recede portions of the cams, in order, beginning with the next to the leading cam in said one direction of rotation and continuing to the last cam trailing in said one direction of rotation, each being successively longer than its immediate predecessor.

4. An apparatus according to claim 1 wherein the run-out portions of the cams, in order, beginning with the next to the leading cam in said one direction of rotation and continuing to the last cam trailing in said one direction of rotation, each being successively shorter and sTeeper than its immediate predecessor.

5. An apparatus according to claim 1 wherein the combined length of the radial components of the recede and run-out portions of each cam is equal to the combined length of the radial components of the recede and run-out portions of each of the other cams.

6. The structure according to claim 2 wherein said recede drive means includes a cam follower on, and rotatable with, the cam member; a complementary cam supported in fixed position along said lineal path; a reversible piston and cylinder assemblage including a piston movable to extended and retracted positions, respectively, and connected to the cam member so that it is in one of said positions when the cam member is in the rotated position in which it holds the carriers in fully receded positions, and it is in the other of said positions when the cam member is in the rotated position in which it holds the carriers in their radial starting position.
