Abstract

As an alternate to attaching small parts with screws, stainless steel dowel pins 11 are pressed through openings in the members 12 and 13 which are to be secured together, pins 11 protruding out evenly on both sides. Member 13 has larger holes to fit easily over the pins 11 and provide enough clearance to move around in all directions to align member 12. A clip 16 is then placed over pins 11 to hold down assembly 13. After the clip is placed, assembly 13 can be moved exactly into the desired position. When exactly in the right position, spotwelding can be used to weld clip 16 to the assembly 13. The holes in clip 13 are smaller than pins 11 so the ears on clip 16 will secure the assembly 13 from any movement. To replace a damaged assembly and to rework the assembly, the ears can be bent upward and lifted off assembly 13.

Method for Small Parts Attachment

As an alternate to attaching small parts with screws, stainless steel dowel pins 11 are pressed through openings in the members 12 and 13 which are to be secured together, pins 11 protruding out evenly on both sides. Member 13 has larger holes to fit easily over the pins 11 and provide enough clearance to move around in all directions to align member 12. A clip 16 is then placed over pins 11 to hold down assembly 13. After the clip is placed, assembly 13 can be moved exactly into the desired position. When exactly in the right position, spotwelding can be used to weld clip 16 to the assembly 13. The holes in clip 13 are smaller than pins 11 so the ears on clip 16 will secure the assembly 13 from any movement. To replace a damaged assembly and to rework the assembly, the ears can be bent upward and lifted off assembly 13. The advantage is that no rework of part 12 is required. Since this method does not create any contamination, it can be used over and over again.
