Method for tightening a Z-head tool spring

Disclosed is a method for tightening a Z-head tool spring. Benefits include improved functionality and improved cost effectiveness.

Background

         Sometimes a Z-head spring does not have the proper tension. The conventional way to tighten it is to remove the Z-head. A seven-inch rod with two pins is used to adjust the spring. The rod is only useful when the Z-head is removed from the machine. The machine is unusable for a couple of hours. Then, the vision must be retaught for every product. A method is required for adjusting the spring without removing the Z-head and requiring the vision to be retaught (see Figure 1).

Description

The disclosed method is a tool compatible with a ratchet that matches up with the z-head spring. This tool enables the tightening of the spring without removing the Z-head (see Figure 2).

         The key elements of the method include two pins mounted to a C-shaped base compatible with a 3/8-inch drive ratchet (see Figure 3).

The disclosed method can be implemented using the following steps:

1. Obtain a high-grade aluminum square block that is 1.1/4-inch by 1.7/8-inch by 1-inch and 21/16-inch (see Figure 4).

2. Have the tool machined in a machine shop.

Advantages

         The disclosed method provides advantages, including:

•         Improved functionality due to enabling a Z-head spring to be tightened without removing the Z-head

•         Improved cost effectiveness due to eliminating the requirement for reteaching the vision for every p...
