Fixture replacement mechanism and method for engine leak detecting device

Abstract

The invention discloses a fixture replacement mechanism and a method for an engine leak detecting device. The mechanism comprises a fixture and a fixture mounting frame; an upper oil cylinder and a fall preventing module are arranged on the fixture mounting frame; a lifting base, a bolt module and an automatic joint module are arranged at the top of the fixture; the bolt module is arranged on one side of the lifting base, and is connected with the lifting base; the automatic joint module is arranged on the outer side of the lifting base; the fall preventing module and the bolt module are respectively positioned on two sides of the lifting base; and the upper oil cylinder is positioned above the lifting base. the method comprises the following steps: during mounting, the fixture is firstly pressed in the fixture mounting frame; the fall preventing module lifts up the lifting base; a bolt is pushed out to connect with the lifting base for fixation; a joint of the upper oil cylinder is connected with the lifting base; the bolt is retreated, and the fall preventing module is deviated from the lifting base; and in the automatic joint module, an upper connecting plate is downwards operated to contact with a lower connecting plate. The mechanism realizes replaceability of the fixture on the same leak detecting device, improves the use flexibility of the leak detecting device, and reduces the equipment cost.

Description

technical field [0001] The invention relates to the technical field of engine leak detection, in particular to a fixture replacement mechanism and method for an engine leak detection device. Background technique [0002] In the automotive field, engine leakage failure is a relatively common and dangerous phenomenon. In order to ensure the normal operation of the engine during use, after the engine casing is manufactured, it is generally necessary to perform a leak test on it. Due to the variety of engine models and specifications, the fixture structures that need to be equipped in the leak detection process are also different. In the current leak detection device, the jig used to clamp the engine workpiece on the detection station is fixed and cannot be replaced. Therefore, each leak detection device can only be used for leak detection of engines of the same specification and model. Generally speaking, the investment cost of the leak detection device is too high, which is n...

Problems solved by technology

In the current leak detection device, the jig used to clamp the engine workpiece on the detection station is fixed and cannot be replaced. Therefore, each leak detection device can only be used for leak detection of engines of the same specification and model. Generally speaking, the investment cost of the leak detection device is too high, which is not conducive to the control of production costs. In addition, every time a model of engine is produced, a set of leak detection device must be equipped, which greatly increases equipment investment and maintenance costs, and occupies an area of It is also large, the use of the leak detection device is not flexible enough, and the utilization rate is difficult to improve
