Inner diameter positioning devices are widely used in tooling to fix and position the reservoirs to complete processes such as welding, pressing, and handling. During the processing of automotive shock absorber reservoirs, there is a requirement for inner diameter positioning or fixing.

It uses the up and down movement of the expansion head to drive the expansion block to expand or contract, thereby changing the diameter. The tension spring ensures that the expansion block does not come out and at the same time ensures a tight fit. The operation process only requires rotating the adjusting shaft wheel, and after adjusting to the correct position, tightening the locking screw to complete the quick adjustment.
