Abstract
A cutting tool retention system for retaining a cutting tool having a tool recess. The cutting tool retention system comprises a support block having a block bore and a block recess intersecting the block bore and a clip movably situated in the block recess, the clip having a spring structure which engages the support block and urges the clip into an engaging relationship with the tool recess of the cutting tool situated within the block bore, the spring structure allowing the clip to be disengaged from an engaging relationship with the tool recess of the cutting tool situated within the block bore by applying force directly to the clip so as to overcome the urging of the spring structure.
Claims27
The cutting tool retention system for retaining a cutting tool having a tool recess, the cutting tool retention system comprising:
- a support block having a block bore and a block recess intersecting the block bore;
- and
- a clip movably situated in the block recess, the clip having a spring structure which engages the support block and urges the clip into an engaging relationship with the tool recess of the cutting tool situated within the block bore, the spring structure allowing the clip to be disengaged from an engaging relationship with the tool recess of the cutting tool situated within the block bore by applying a force directly to the clip so as to overcome the urging of the spring structure.
The cutting tool retention system for retaining a cutting tool having a tool recess, the cutting tool retention system comprising:
- a support block having a block bore and a block recess intersecting the block bore, the block recess defining a clip spreader;
- and
- a clip in the block recess, the clip having a clip leg, the clip leg being displaced by the clip spreader when the clip is operably moved such that the clip leg will not engage the tool recess of the cutting tool situated within the block bore, the clip leg engaging the tool recess when the clip is not operably moved.
A cutting tool retention system for retaining a cutting tool having a tool recess, the cutting tool retention system comprising:
- a support block having a block bore and a block recess intersecting the block bore, the block recess defining a clip saddle;
- and
- a clip residing within the block recess and capable of being moved to engage or disengage the tool recess of the cutting tool inserted in the block bore, the clip having an operator end and clip legs extending from the clip operator end, the clip legs having retainer projections, the clip operator end, the clip legs and retainer projections partially encircling the clip saddle and the block bore so as to prevent the clip from being dislodged from residing within the block recess when the cutting tool is situated within the block bore.
A clip for use with a cutting tool having a tool recess and a support block having a block bore and a block recess intersecting the block bore, the block recess having a clip saddle and a clip spreader, the clip comprising:
- a clip operator end;
- and
- a clip leg extending from the clip operator end which is displaced by the clip spreader when the clip is operably moved such that the clip leg will not engage the tool recess of the cutting tool situated within the block bore, the clip leg engaging the tool recess of the cutting tool situated within the block bore when the clip is not operably moved.
A support block for use with a cutting tool having a tool recess and a clip having a clip operator end and clip legs extending from the clip operator end, the support block comprising:
- a support block body having a block bore and a block recess intersecting the block bore, the block recess having a clip saddle and clip spreader which are flanked by the clip legs of the clip when the clip is operably inserted into the block recess such that the clip legs are displaced by the clip spreader when the clip is operably moved such that the clip legs will not engage the tool recess of the cutting tool situated within the block bore and the clip legs will engage the tool recess of the cutting tool situated within the block bore when the clip is not operably moved.
A method for retaining a cutting tool having a tool recess in a support block having a block bore and block recess by using a clip and a spring structure, the method comprising:
- situating the clip in a block recess such that the clip protrudes into the block bore;
- applying force to the clip such that the clip no longer protrudes into the block bore and the spring structure is activated;
- inserting the cutting tool within the block bore such that the tool recess is located adjacent the block recess;
- and
- releasing the clip such that the spring structure forces the clip to protrude into the block bore and into an engaging relationship with the tool recess.
A method for retaining a cutting tool having a tool recess in a support block having a block bore and a block recess intersecting the block bore, the method comprising:
- movably situating a clip having a spring structure in the block recess such that the clip will be urged by the spring structure to protrude into the block bore and engage the tool recess of the cutting tool inserted into the block bore unless a force is applied directly to the clip so as to overcome the urging of the spring structure.
A cutting tool retention system for retaining a cutting tool having a tool recess, the cutting tool retention system comprising:
- a support block having a block bore and a block recess intersecting the block bore;
- a clip movably situated in the block recess, the clip having a spring structure which engages the support block and urges the clip into an engaging relationship with the tool recess of the cutting tool situated within the block bore, the spring structure allowing the clip to be disengaged from an engaging relationship with the tool recess of the cutting tool situated within the block bore by applying a force directly to the clip so as to overcome the urging of the spring structure;
- and
- wherein the block recess of the support block has a clip spreader and the spring structure has a clip leg which engages the clip spreader and urges the clip into the engaging relationship with the tool recess of the cutting tool situated within the block bore, the clip leg allowing the clip to be disengaged from the engaging relationship with the tool recess of the cutting tool situated within the block bore by a user applying force directly to and moving the clip such that the clip leg is displaced and no longer engages the tool recess of the cutting tool.
A cutting tool retention system for retaining a cutting tool having a tool recess, the cutting tool retention system comprising:
- a support block having a block bore and a block recess intersecting the block bore;
- a clip movably Situated in the block recess, the clip having a spring structure which engages the support block and urges the clip into an engaging relationship with the tool recess of the cutting tool situated within the block bore, the spring structure allowing the clip to be disengaged from an engaging relationship with the tool recess of the cutting tool situated within the block bore by applying a force directly to the clip so as to overcome the urging of the spring structure;
- and
- wherein the block recess has a clip saddle which limits movement of the clip when force is applied directly to the clip so as to overcome the urging of the spring structure.
