Description

Technical Field

[0001] The utility model relates to a checking tool, in particular to a checking tool used for checking whether the coordinates of each longitudinal point of an oil return pipe of an automobile supercharger are qualified. Background Art

[0002] It is well known in the automotive turbocharger manufacturing field that both the automotive supercharger intermediate and the engine oil tank sump are equipped with oil return pipes, so that the oil entering the automotive supercharger intermediate is sent to the oil filter through the oil pump for filtration, and then sent to the automotive supercharger intermediate. This requires the installation of an oil return pipe between the automotive supercharger intermediate and the engine oil tank sump. In order to avoid the interference of automotive parts between the automotive supercharger intermediate and the engine oil tank sump, the longitudinal direction of the oil return pipe mostly presents multiple bending points bent in different directions. These oil return pipes with multiple bending points will inevitably have errors during the bending process. Therefore, it is necessary to inspect the oil return pipe after bending.

[0003] At present, the inspection method for the oil return pipe is a manual method, that is, using a clamp to inspect the bending degree of each point in the longitudinal direction of the oil return pipe. Although the manual method can realize the inspection of the bending degree of each point in the longitudinal direction of the oil return pipe, the inspection is more troublesome and the work efficiency is low. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a supercharger oil return pipe inspection tool. The use of the inspection tool to inspect the oil return pipe of the automobile supercharger is not only relatively simple but also has high working efficiency.

[0005] The above-mentioned problem to be solved by the utility model is achieved by the following technical solutions:

[0006] The utility model is characterized in that the supercharger oil return pipe inspection fixture includes a base plate, which is a rectangular flat plate, and a first coordinate block and a fourth coordinate block are respectively provided on a pair of diagonal corners. The first and fourth coordinate blocks are both flat plates, and their plate surfaces are parallel. There are a second coordinate block and a third coordinate block between the first coordinate block and the fourth coordinate block. The lower sides of the first coordinate block, the second coordinate block, the third coordinate block and the fourth coordinate block are connected to the base plate, and their upper sides are provided with grooves that cooperate with the oil return pipe to be inspected. The second coordinate block is lower than the third coordinate block. There is a spacing between the first coordinate block, the second coordinate block, the third coordinate block and the fourth coordinate block.

[0007] A further improvement of the utility model is that there are two handles on the bottom plate, and the two handles are respectively located on another pair of opposite corners of the bottom plate.

[0008] It can be seen from the above scheme that since the supercharger return oil pipe inspection fixture of the utility model contains a base plate, the base plate is a rectangular flat plate, and a first coordinate block and a fourth coordinate block are respectively provided on a pair of diagonal corners. The first and fourth coordinate blocks are both flat plates, and their plate surfaces are parallel. There are a second coordinate block and a third coordinate block between the first coordinate block and the fourth coordinate block. The lower sides of the first coordinate block, the second coordinate block, the third coordinate block and the fourth coordinate block are connected to the base plate, and their upper sides all have grooves that cooperate with the oil return pipe to be inspected. The second coordinate block is lower than the third coordinate block. The first coordinate block, the second coordinate block, the third coordinate block and the fourth coordinate block are spaced apart from each other.

[0009] The first coordinate block, the second coordinate block, the third coordinate block and the fourth coordinate block at different heights and coordinate positions are used to pre-position the coordinates of each point in the longitudinal direction of the oil return pipe to be inspected. During inspection, the oil return pipe can be inspected by simply embedding the two ends of the oil return pipe to the grooves on the first to fourth coordinate blocks. Compared with the manual inspection method used in the background technology, the inspection is not only simpler, but also greatly improves the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a three-dimensional schematic diagram of a supercharger oil return pipe inspection fixture of the utility model. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, the supercharger oil return pipe inspection fixture of the utility model contains a base plate 1, which is a rectangular flat plate, and a first coordinate block 2 and a fourth coordinate block 6 are respectively arranged on a pair of diagonal corners. The first and fourth coordinate blocks 6 are both flat plates, and their plate surfaces are parallel. There are a second coordinate block 3 and a third coordinate block 5 between the first coordinate block 2 and the fourth coordinate block 6. The lower sides of the first coordinate block 2, the second coordinate block 3, the third coordinate block 5 and the fourth coordinate block 6 are all fixed on the base plate 1, and their upper sides are all processed with grooves that match the oil return pipe 7 to be inspected. The second coordinate block 3 is lower than the third coordinate block 5. The first coordinate block 2, the second coordinate block 3, the third coordinate block 5 and the fourth coordinate block 6 are all spaced apart from each other. During inspection, the two ends of the oil return pipe 7 are respectively embedded in the grooves on the upper sides of the first coordinate block 2 and the fourth coordinate block 6, and the corresponding longitudinal points of the oil return pipe 7 are respectively embedded in the corresponding grooves on the upper sides of the second coordinate block 3 and the third coordinate block 5. If the two ends and longitudinal points of the oil return pipe 7 can be respectively embedded in the grooves on the first coordinate block 2 and the fourth coordinate block 6 and the grooves on the second coordinate block 3 and the third coordinate block 5 without external force, it means that the oil return pipe 7 is a qualified product. Otherwise, it is a failed product.

[0012] For easy transportation, two handles are fixed on the base plate 1 , and the two handles are respectively located on another pair of diagonal corners of the base plate 1 .
