Embodiment 1

[0038] Embodiment 1: A special inspection tool for the engine warm air outlet pipe in this embodiment 1 is used to inspect the positions of the installation holes on the warm air outlet pipe, such as figure 1 As shown, the warm air outlet pipe 1 includes a flange 11 connected to the water outlet of the engine and having a water outlet hole, an upper pipe 12 and a lower pipe 13 that are integrally structured with the flange and the nozzle is suspended, and a nozzle is designed at the nozzle Fixed plate 14, the middle section of upper and lower pipes is connected to each other by connecting plate 15 that is provided with connecting hole, as figure 2 and image 3 As shown, the special inspection tool includes a base 2, a clamping mechanism 3 installed on the base and a detection device 4. The base includes a long wall 21 and a short wall 22 with an integral structure and distributed at right angles; The structure includes a flange positioning block 23 and a horizontal shelf pla...

Embodiment 2

[0041] Embodiment 2: A special inspection tool for the engine warm air outlet pipe in Embodiment 2, such as Figure 5 and Figure 6 As shown, it also includes an auxiliary clamping cylinder 34, the auxiliary clamping cylinder is fixed on the outer surface of the long wall of the base and is perpendicular to the outer surface, the long wall of the base is provided with an opening, and the piston rod of the auxiliary clamping cylinder passes through the base through the opening. From the long wall of the seat to the inner side of the long wall, the piston rod is located below the shelving plate, and a rotatable clamping rod 35 that is at right angles to the piston rod is installed at the end of the piston rod. When the warm air outlet pipe is placed, the clamping rod is in the shape of The flat state is convenient for the inlet and outlet of the warm air outlet pipe. When clamping is required, the clamping rod is rotated 90°, the rod mouth faces up and corresponds to the middle ...

Abstract

The invention discloses a special gauge for an engine warm air water outlet pipe and a detection method. The special gauge comprises a base, a clamping mechanism installed on the base, and a detecting device. The base is provided with a locating structure. The clamping mechanism comprises a clamping air cylinder and a clamping piece. The detection device comprises a plurality of detecting air cylinders fixedly arranged on the base, probes and probing bars, wherein the probes and the probing bars are arranged on the end portions of the detection air cylinders. The special gauge is adopted for locating and clamping the warm air water outlet pipe of a three-dimensional space shape, the probes and the probing bars are utilized for carrying out corresponding position detection on three installation parts of the warm air water outlet pipe, detection is convenient and fast, and the accuracy and the working efficiency of detection are improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a convenient, fast and accurate special inspection tool for an engine warm air outlet pipe and a detection method. Background technique [0002] The warm air outlet pipe is one of the important parts of the engine heater system. It is mainly used for the cooling cycle of the car, reducing the temperature of the engine when it is working, so as to improve the service life of the engine. Because the warm air outlet pipe is a welded pipe The position of the mounting bracket is related to the shape of the engine and the installation space. The shape is irregular and three-dimensional, and it is difficult to accurately detect and locate the relevant dimensions. As a result, the engine cannot be installed, which directly affects the production efficiency of the engine. At present, the main method of detecting the engine warm air outlet pipe is to detect the relevant dimensions through three coordi...
