Box part bowl-shaped plug press-fitting clamp

Abstract

The invention discloses a box part bowl-shaped plug press-fitting clamp which comprises an inner cavity and a clamp body matched with outer profile of a box part. Air cylinders are arranged at positions, corresponding to sand outgoing holes of the box part, on two sides of the clamp body respectively, and an extensible end of each air cylinder faces the inner cavity of the clamp body and provided with a floating press head. By additionally arranging the air cylinders with the floating press heads, a user only needs to mount the clamp on the box part in a buckled manner and drive the air cylinders to enable the floating press heads to press a bowl-shaped plug into the sand outgoing holes of the box part. The box part bowl-shaped plug press-fitting clamp is simple in structure, low in cost, low in labor intensity and suitable for manufacturing of engine boxes.

Description

technical field [0001] The invention relates to a processing tool for engine box parts, in particular to a bowl-shaped plug press-fitting fixture for box parts. Background technique [0002] Before the present invention was proposed, there were a large number of sand outlet holes in the casting process of the engine case parts, such as: there were sand outlet holes on both sides of the engine case parts. On the machining line, these sand holes need to be blocked with bowl-shaped plugs, and the plugging methods generally include manual and fully automatic methods. [0003] 1. For the manual method, that is, manually knocking the bowl-shaped plug into the sand outlet hole, this method is likely to cause the bowl-shaped plug to be knocked skewed and not pressed properly, which will cause oil and water leakage from the engine; moreover, due to Each bowl-shaped plug needs to be knocked 5-6 times on average, so the labor intensity is high, and long-term operation can easily lead ...

Problems solved by technology

[0003] 1. For the manual method, that is, manually knocking the bowl-shaped plug into the sand outlet hole, this method is likely to cause the bowl-shaped plug to be knocked skewed and not pressed properly, which will cause oil and water leakage from the engine; moreover, due to Each bowl-shaped plug needs to be tapped 5-6 times on average, so the labor intensity is high, and long-term operation can easily lead to muscle strain and frozen shoulder.

[0004] 2. For the fully automated method, that is, the automatic pressing of the bowl plug is realized through hydraulic and servo-driven manipulators. This method has high investment costs, large floor space, high failure rate, and complicated equipment maintenance.
