Engine water blocking cover pulling and detaching tool and pulling and detaching method thereof

Abstract

The invention discloses an engine water blocking cover pulling and detaching tool. The engine water blocking cover pulling and detaching tool comprises a cover pulling nut which is installed below a to-be-pulled-and-detached water blocking cover, a spiral lifting device which is installed above the to-be-pulled-and-detached water blocking cover and a cover pulling pull rod; the cover pulling nut is provided with a first threaded hole which is arranged in the center; the first threaded hole is corresponding to a central hole of a water blocking cover; the spiral lifting device is installed above the to-be-pulled-and-detached water blocking cover; the bottom end of the pulling cover pull rod is provided with a first external thread portion; the first external thread portion perpendicularly penetrates the central hole of the water blocking cover to be connected with the first threaded hole; the cover pulling nut is driven to move upward by screwing the cover pulling pull rod. According to the engine water blocking cover pulling and discharging tool, the structure is simple, the utilization is convenient, the water blocking cover is rapidly detached from a cylinder cover, the cylinder cover hole wall accuracy is not damaged after detachment, the cylinder cover can be reused, resource waste is reduced, and manufacturing costs are reduced. The invention also provides a water blocking cover pulling and detaching method.

Description

Technical field [0001] The invention relates to the technical field of engine parts manufacturing, in particular to a tool and a method for pulling out and removing an engine water blocking cover. Background technique [0002] In the automobile industry, the auto parts manufacturing industry conducts large-scale automated production, so a large number of defective machining parts often occur due to equipment or personnel problems, especially in the process of producing engine blocks and cylinder heads in automobile production plants. When the cylinder head line is produced, it is necessary to use a robot to apply glue. If there is an equipment failure or insufficient glue during the robot application, part of the glue or missed coating will occur. If after the equipment camera detection and the engine assembly line leak test, the cylinder head needs to be repaired and the water blocking cover is removed from the cylinder head. [0003] In the prior art, a pin puller is often used ...

AI Technical Summary

Problems solved by technology

Usually, the expansion bolt of the pin puller will come out of the water blocking cover, resulting in operation failure; sometimes even if the water blocking In the process of blocking the cover, the outer edge of the water blocking cover gnaws the hole wall of the cylinder head, so that the cylinder body is scrapped; and the expansion bolt in the pin puller needs to be replaced every time it is pulled out, resulting in a large number of expansion bolts waste, which increases the cost
