Description

Technical Field

[0001] This invention relates to the field of body-in-white assembly and processing technology, and in particular to a pin cylinder triggering device and its usage method. Background Technology

[0002] like Figure 1 As shown, during the production process of the body-in-white 100, the body-in-white 100 needs to be moved to multiple different stations on the production line in sequence. Whether the body-in-white 100 can be accurately positioned at each station is the key factor that determines the manufacturing precision of the body-in-white 100.

[0003] To ensure accurate positioning of the body-in-white 100 at each workstation, multiple positioning holes 101 need to be machined on the base plate of the body-in-white 100. A hook-and-pin cylinder 1 is installed on the tooling base at each workstation, corresponding to each positioning hole 101. When the body-in-white 100 moves to the tooling base at the corresponding workstation, the positioning pin 11 of the hook-and-pin cylinder 1 inserts into the corresponding positioning hole 101, achieving horizontal positioning of the body-in-white. The positioning pin 11 contains a pull rod that can move axially along the positioning pin, and the upper end of the pull rod has a radially outward-pointing mechanism along the positioning pin. The extended hook 12 has a magnetic ring at the lower end of the pull rod. The outer side of the hook cylinder 1 is equipped with a magnetic switch for detecting whether the hook is clamped in place. After the positioning pin 11 of the hook cylinder is inserted into the positioning hole 101, the electronic control system controls the pull rod to move downward, so that the lower end of the hook 12 presses against the upper end of the side wall of the positioning hole 101. At the same time, the magnetic ring and the magnetic switch are aligned vertically, thereby triggering the magnetic switch. After the electronic control system receives the trigger signal from the magnetic switch, it indicates that the white body 100 is accurately positioned and meets the conditions for proceeding to the next action.

[0004] To trigger the magnetic switch of the hook cylinder, the magnetic ring must be flush with the magnetic switch when the hook 12 clamps the side wall of the positioning hole 101. Therefore, the wall thickness of the positioning hole 101 must be uniform. However, since the positioning hole 101 is formed by stamping, some positioning holes 101 may have burrs or flange protrusions on their walls (such problems do not affect the accuracy of the body-in-white). This causes the magnetic ring to be unable to align with the magnetic switch when the hook 12 clamps the side wall of the positioning hole 101. As a result, even though the body-in-white 100 is already clamped in place, the magnetic switch signal cannot be triggered, so the conditions for the next action at the workstation cannot be met, the production line cannot continue to execute the automatic sequence, and thus production stops. Summary of the Invention

[0005] The technical problem to be solved by this invention is that when there are burrs or flange protrusions on the wall of the positioning hole of the body-in-white, the magnetic ring of the locking cylinder cannot trigger the magnetic switch after the locking cylinder clamps the body-in-white, resulting in production line stoppage.
