Non-destructive cold extractions of press fit bushings
An assembly for removing a bushing is provided including a mandrel having a size and shape similar to the bushing and a receiver having a hollow interior cavity. A fastener extends through an opening formed in both the mandrel and the receiver. A socket attachment has a first opening configured to removably couple to a first end of the fastener and a second opening configured to removably couple to a torque delivery tool. A biasing mechanism arranged adjacent a second end of the fastener is configured to generate a biasing force to drive the mandrel against a bushing in response to a coupling of the socket attachment and the fastener.
1. An assembly for removing a bushing, comprising:
a mandrel having a size and shape similar to the bushing;
a receiver having a hollow interior cavity;
a fastener extending through an opening formed in both the mandrel and the receiver;
a socket attachment having a first opening configured to removably couple to a first end of the fastener and a second opening configured to removably couple to a torque delivery tool; and
a biasing mechanism arranged adjacent a second end of the fastener, the biasing mechanism being configured to generate a biasing force to drive the mandrel against the bushing in response to a coupling of the socket attachment and the fastener.
2. The assembly according to claim 1 , wherein the mandrel includes at least one chamfer configured to ensure proper engagement with a bushing.
3. The assembly according to claim 1 , wherein the first end of the fastener includes a plurality of first threads and the first opening of the socket attachment includes a plurality of second threads, the plurality of second threads being complementary to the plurality of first threads.
4. The assembly according to claim 1 , wherein the biasing mechanism comprises a coil spring.
5. The assembly according to claim 1 , wherein the biasing mechanism is positioned between a portion of the fastener and the mandrel.
6. The assembly according to claim 1 , wherein the biasing mechanism is positioned between a portion of the fastener and the receiver.
7. The socket attachment according to claim 1 , wherein the torque delivery tool is a wrench.
8. The socket attachment according to claim 7 , wherein the torque delivery tool is a socket wrench and the second opening is configured to receive a post extending from a head of the socket wrench.
9. The socket attachment according to claim 1 , further comprising:
a mandrel arranged adjacent a bushing, the mandrel having a size and shape similar to the bushing;
a receiver having a hollow interior cavity;
a fastener extending through an opening formed in both the mandrel and the receiver, the socket attachment being coupled to a first end of the fastener; and
a biasing mechanism arranged adjacent a second end of the fastener, the biasing mechanism being configured to generate a biasing force to drive the mandrel against the bushing in response to a coupling of the socket attachment and the fastener.
