Embodiment Construction

[0011] Such as figure 1 , figure 2 shown. The present invention consists of a frame 3, a leak detection tool 4 and a water tank 5. The frame 3 is a cone structure. Frame 3 is connected with external air source and power supply, and the top of frame 3 is provided with power supply control box 12, lifting cylinder 1 and guide rod 13. The side end of the frame 3 is provided with an air source treatment triplex 10, a pressure reducing valve 2, a control valve 9 and a connecting air pipe. The top plate 18 of the airtightness detection tool 4 is provided with a connection hole that cooperates with the lifting cylinder 1 and the guide rod 12 at the top of the frame 3. The shape and relative position of the connection hole are determined in the initial design, and it has versatility. The top plate 18 and the bottom plate 16 is connected as a whole by connecting rod 17. The frame 3 is connected with the replaceable special sealing test tool 4 through the lifting cylinder 1 and th...

Abstract

The invention discloses leak detection equipment, belonging to the technical field of tightness detection, and solving the problem of poor interchangeability of the existing leak detection equipment. The leak detection equipment is mainly characterized by being composed of a rack, tightness detection equipment and a water tank, wherein the rack is provided with a power supply control box, a lifting cylinder, a guide bar, an air source processing triple piece, a reducing valve and a control valve; the tightness detection equipment is provided with a pneumatic sealing mechanism, a pneumatic clamping mechanism and a connecting hole matched with the lifting cylinder and the guide bar, wherein the pneumatic clamping mechanism and the pneumatic sealing mechanism are connected with the control valve via a pressure hose and a quick coupling; and the lower end of the rack is connected with the water tank via a zouma hole and a bolt. The leak detection equipment is convenient in assembling and disassembling operation, is reliable in operation, has low cost and good interchangeability, can realize one machine with multiple functions, can definitely display the defect position of leaked workpiece, is mainly used for tightness detection for the auto parts, such as an aluminium alloy intake manifold, a cylinder body, a cylinder cover, an oil pan, an oil filter seat and the like.

Description

technical field [0001] The invention belongs to the technical field of airtightness detection. It specifically relates to a leak detection device that can be used for leak detection of aluminum alloy intake manifolds, cylinder blocks, cylinder heads, bottom shells, engine oil filter seats and the like of auto parts. Background technique [0002] At present, domestic airtight testing equipment for aluminum alloy intake manifolds, cylinder blocks, cylinder heads, oil pans, oil filter seats, etc. Instrument and electric or hydraulic control system, wherein, the workpiece fixture to be tested is a non-replaceable structure, and each workpiece fixture to be tested needs to be equipped with corresponding special leak detection equipment. Its shortcomings are firstly that the manufacturing cost is high; secondly, the special machine is dedicated, and if the production is changed, the whole machine will be idle; thirdly, it is not easy to judge the specific defect location of the w...
