A sliding head locking pin clamp is provided having a housing with a housing bore extending axially therethrough along a first axis. An end cap has an end cap bore extending therethrough along the first axis, wherein the end cap is operably coupled to a first end of the housing. A shaft has a shaft bore extending through the shaft along the first axis, wherein an outer diameter of a first end of the shaft generally defines a first portion of a locating pin. The first portion of the locating pin is in axial sliding engagement with at least a first portion of the end cap bore. The shaft has a shaft hole extending radially through the shaft along a second axis, wherein the second axis is perpendicular to the first axis. The shaft further has a shaft guide rod generally fixedly positioned in the shaft hole. A piston is coupled to the shaft and is in sliding engagement with the housing bore to linearly translate the shaft between a first axial position and a second axial position along the first axis. A slider has a slider hole extending radially therethrough, wherein the shaft guide rod is in linear sliding engagement with the slider hole, therein providing a linear translation of the slider with respect to the shaft along the second axis between a first radial position and a second radial position. The slider has a rod member extending through a first end of shaft bore and comprising a tip having an engagement lip, wherein the tip of the rod member generally defines a second portion of the locating pin. A cam follower also extends radially from the slider. A cam block has a cam block bore extending into the cam block along the first axis, wherein the cam block comprises a cam channel defined in a sidewall of the cam block bore. A portion of the slider is configured to reside within the cam block bore and wherein the cam follower is in sliding engagement with the cam channel. In the first axial position and first radial position, the first and second portions of the locating pin are configured to pass through a locating hole of a workpiece. In the second axial position and second radial position, the rod member is configured to clamp the workpiece between the engagement lip and the end cap. The first radial position and second radial position are governed by the sliding engagement between the shaft guide rod and the slider hole, and the sliding engagement between the cam follower and the cam channel upon the linear translation of the shaft between the first axial position and second axial position. |

1. A sliding head locking pin clamp, comprising:
a housing having a housing bore extending axially into the housing, therein defining a first axis; an end cap having an end cap bore extending therethrough along the first axis, wherein the end cap is operably coupled to a first end of the housing; a shaft, comprising:
a shaft bore extending through the shaft along the first axis;an outer diameter of a first end of the shaft generally defining a first portion of a locating pin, wherein the first portion of the locating pin is in axial sliding engagement with at least a first portion of the end cap bore;a shaft hole extending radially through the shaft along a second axis, wherein the second axis is perpendicular to the first axis; anda shaft guide rod generally fixedly positioned in the shaft hole; a piston generally fixedly coupled to the shaft, wherein the piston is in sliding engagement with the housing bore and configured to linearly translate the shaft between a first axial position and a second axial position along the first axis; a slider, comprising:
a slider hole extending radially therethrough, wherein the shaft guide rod is in linear sliding engagement with the slider hole, therein providing a linear translation of the slider with respect to the shaft along the second axis between a first radial position and a second radial position;a rod member extending through a first end of shaft bore and comprising a tip having an engagement lip, wherein the tip of the rod member generally defines a second portion of the locating pin; anda cam follower extending radially from the slider; and a cam block having a cam block bore extending into the cam block along the first axis, wherein the cam block comprises a cam channel defined in a sidewall of the cam block bore, wherein a portion of the slider is configured to reside within the cam block bore and wherein the cam follower is in sliding engagement with the cam channel, and wherein, in the first axial position and first radial position, the first and second portions of the locating pin are configured to pass through a locating hole of a workpiece, wherein in the second axial position and second radial position, the rod member is configured to clamp the workpiece between the engagement lip and the end cap, and wherein the first radial position and second radial position are generally governed by the sliding engagement between the shaft guide rod and the slider hole and the sliding engagement between the cam follower and the cam channel upon the linear translation of the shaft between the first axial position and second axial position. |
