Specification
CLAIMS
What is claimed is:
1. A rivet upsetting tool with closed loop feedback system, comprising:
a pop-out mechanism housed inside the tool (5), which provides feedback, wherein said pop-out mechanism consists of a cylindrical plunger (6) secured with the spring (7) mechanism and the tip of the plunger (6) is projected beyond the surface, being pushed by the side surface of the shop formed head; and the plunger (6) makes contact with the photo electric sensor (8), which converts the mechanical movement of the plunger (6) to electrical signal and transmits it to the LED (9), which in turn gives the indication.
2. The rivet upsetting tool with closed loop feedback system as claimed in claim 1, characterized in that, the closed loop feedback mechanism gives the operation completion indication by LED (9) lamp which enables the operator to complete the operation in single stretch avoiding the intermittent stoppage of bucking operation for verification.
