Abstract
Abstract A fixture for presetting cutting tools in the tool holders of a single spindle cam actuated turret lathe whereby set up time is substantially reduced. This invention simulates the position of a workpiece in relation to a turret end-forming tool by the use of the actual turret cam to be used for production. A rigid base with a protruding shaft provides a mount for the turret cam. A first slide, movable in a guideway in the base, has its position determined by a cam follower actuated by the lobes of the turret cam. Forming part of the slide are means to hold a turret tool holder. A second slide, also movable in the guideway, has length determining means and a reference pointer. With appropriate use of the length measuring means, the reference pointer will indicate the proper depth of the tool''s shank within the tool holder. By use of a second measuring means on the second slide a tool, such as a boring tool, can be positioned off-center within the tool holder. An attachment permits a similar presetting of circular-forming tools within cross slide holders.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
191 words
A presetting fixture for a cam actuated turret lathe including: a rigid base having a guideway; a support member on the base on which a turret cam, to be used for presetting, can be mounted; a first and a second slide each independently movable in the guideway; turret-collet simulating means including retaining means on the first slide in which a turret tool holder can be held and reference means on the second slide for representing axial positions on a workpiece held by a collet; a cam follower on either of said slides to permit said slide to be positioned by the lobes of the turret cam mounted on the support member; measuring means on the other slide for determining its position relative to the slide with the cam follower; and diameter reference means operably connected to the second slide for positioning a tool off center within the turret tool holder, the diameter reference means including a diameter guideway in the second slide running perpendicular to the base guideway, a diameter slide movable in said diameter guideway, and diameter measuring means for determining the position of the diameter slide within its guideway.
Claim 2
Dependent Claim
191 words
A presetting fixture for a cam actuated turret lathe including: a rigid base having a guideway; a support member on the base on which a turret cam, to be used for presetting, can be mounted; a first and a second slide each independently movable in the guideway; turret-collet simulating means including retaining means on the first slide in which a turret tool holder can be held and reference means on the second slide for representing axial positions on a workpiece held by a collet; a cam follower on either of said slides to permit said slide to be positioned by the lobes of the turret cam mounted on the support member; measuring means on the other slide for determining its position relative to the slide with the cam follower; and diameter reference means operably connected to the second slide for positioning a tool off center within the turret tool holder, the diameter reference means including a diameter guideway in the second slide running perpendicular to the base guideway, a diameter slide movable in said diameter guideway, and diameter measuring means for determining the position of the diameter slide within its guideway.
Claim 3
Dependent Claim
207 words
A presetting fixture for a cam actuated turret lathe including: a rigid base having a guideway; a support member on the base on which a turret cam, to be used for presetting, can be mounted; a first and a second slide each independently movable in the base guideway; retaining means on the first slide in which a tool holder can be held; a diameter guideway in the second slide running perpendicular to the base guideway; a diameter slide movable in said diameter guideway; diameter measuring means responsive to movement of the diameter slide whereby the latter''s position within the diameter guideway can be determined; a fine adjustment guideway in the first slide running parallel to the base guideway; a fine adjustment slide movable in said fine adjustment guideway; a fine adjustment measuring means for determining the position of the fine adjustment slide in its guideway; a cam follower on the fine adjustment slide to position the first slide in the base guideway by means of the lobes of the turret cam mounted on the support member; a reference means carried by the second slide; and length measuring means responsive to movement of the second slide for determining its position relative to the position of the first slide.
Claim 4
Dependent Claim
207 words
A presetting fixture for a cam actuated turret lathe including: a rigid base having a guideway; a support member on the base on which a turret cam, to be used for presetting, can be mounted; a first and a second slide each independently movable in the base guideway; retaining means on the first slide in which a tool holder can be held; a diameter guideway in the second slide running perpendicular to the base guideway; a diameter slide movable in said diameter guideway; diameter measuring means responsive to movement of the diameter slide whereby the latter''s position within the diameter guideway can be determined; a fine adjustment guideway in the first slide running parallel to the base guideway; a fine adjustment slide movable in said fine adjustment guideway; a fine adjustment measuring means for determining the position of the fine adjustment slide in its guideway; a cam follower on the fine adjustment slide to position the first slide in the base guideway by means of the lobes of the turret cam mounted on the support member; a reference means carried by the second slide; and length measuring means responsive to movement of the second slide for determining its position relative to the position of the first slide.
Claim 5
Dependent Claim
71 words
The presetting fixture for a cam actuated turret lathe as defined in claim 2 including: a rigid block mountable on the base; at least one keyway in said block in which a cross slide tool holder may move, said keyway positioned to coact with the reference means; and bracket means for marking the position of the preset cross slide tool holder in the keyway of the cross slide tool presetting means.
