Locking pin clamp

A pin clamp, comprising:

• a housing having a bore extending therethrough, therein defining an axis, wherein the housing comprises first and second actuator holes defined therethrough, wherein the first and second actuator holes extend radially with respect to the axis and are opposed to one another by 90 degrees;
• a shaft in sliding engagement with at least a first portion of the bore, wherein the shaft comprises a radial shaft hole associated with a distal end thereof;
• a piston coupled to the shaft, wherein the piston is in sliding engagement with a second portion of the bore;
• a clevis having a clevis base and two clevis prongs extending from the clevis base generally parallel to the axis, wherein each clevis prong comprises a radial prong hole extending therethrough generally perpendicular to the axis, wherein the clevis base comprises an axial hole along the axis and first and second radial clevis holes generally perpendicular to the axis, wherein the first and second radial clevis holes are opposed to one another by 90-degrees, wherein the axial hole is configured to accept the distal end of the shaft, and wherein the clevis base is configured to couple the clevis to the shaft in each of four 90-degree-opposed positions with respect to the shaft and housing via a selective engagement of a clevis fastener passing through one of the first and second radial clevis holes in the clevis base and the radial shaft hole in the shaft;
• a locating pin having an internal cavity extending axially from a mounting portion thereof and radially through an opening in a sidewall of the locating pin, wherein the mounting portion of the locating pin is configured to be selectively coupled to the housing in one of the four 90-degree-opposed positions with respect to the shaft and housing;
• a clamping arm having a tang end and an engagement end, wherein a slot is defined between the tang end and engagement end, therein defining a cam surface, and wherein the tang end comprises a tang hole therethrough;
• an actuator pin selectively coupled to the housing and extending radially through one of the first and second actuator holes based on an orientation of the clamping arm with respect to the housing, wherein the actuator pin further extends through the slot in the clamping arm, therein defining a cam follower;
• and
• a clevis pin configured to selectively couple the tang end of the clamping arm to the clevis, wherein the clevis prongs sandwich the clamping arm therebetween and wherein the clevis pin passes through the tang hole in the clamping arm and selectively engages the radial prong hole of the clevis prongs, therein providing a pivot for the clamping arm, and wherein the actuator pin extends through the slot in the clamping arm, therein providing a rotational engagement of the clamping arm with respect to the clevis and a sliding engagement between the slot in the clamping arm and the actuator pin, and wherein the engagement end of the clamping arm is configured to extend and retract through the opening in the sidewall of the locating pin based on an axial position of the shaft with respect to the housing.
