Description

Special tool for removing filter cover

Technical Field

The utility model relates to the technical field of filter end cover disassembly tools, in particular to a special tool for disassembly of the filter end cover.

Background Art

Due to the unique appearance design of the PZU-160X20F-S oil return filter and the LXZ-160X80L-S oil suction filter end cover, it is impossible to disassemble it using common tools. For example, when workers currently use ordinary adjustable wrenches to disassemble the PZU-160X20F-S oil return filter and the LXZ-160X80L-S oil suction filter end cover, they clamp the adjustable wrench bayonet into the diagonal inner groove, then use the thumb to adjust the turbine to determine the size of the wrench, then hold the handle of the adjustable wrench and turn it counterclockwise to remove the end cover; or workers use heavy-duty pipe pliers to disassemble the PZU-160X20F-S oil return filter and the LXZ-16 When removing the end cap of the 0X80L-S oil filter, clamp the pipe clamp on the diagonal inner groove, then use the thumb to adjust the hand wheel to determine the size of the wrench, then hold the handle of the heavy-duty pipe clamp and turn it counterclockwise to remove the end cap; however, due to the sharp and shallow inner groove of the filter end cap (only 3mm deep), the wrenches at both ends of the adjustable wrench cannot be effectively stuck after being inserted into the inner groove of the filter end cap, and the accurate fulcrum point cannot be found. In addition, the torque of the adjustable wrench is not large, so the end cap cannot be removed smoothly. Although the heavy-duty pipe clamp has a large torque, it still faces the problem of the pliers head being unable to be positioned because the inner groove of the filter end cap is sharp and shallow (only 3mm deep), resulting in the force being nowhere to be used and the end cap cannot be removed. For this reason, we propose a special tool for removing the filter end cap.

Utility Model Content

In view of the problems in the prior art, the utility model provides a special tool for disassembling a filter end cover.
