Abstract

The utility model discloses a tool for checking the positions of holes of an exhaust manifold boost flange, belonging to the technical field of an engine exhaust manifold. The tool comprises a detection plate which is provided with a detection pin, a left core tire, a right core tire, a front core tire and a back core tire, wherein screw rods are arranged between the left core tire and the right core tire and the front core tire and the back core tire; pressing covers are positioned on the left core tire and the right core tire; springs are installed between the left and right core tires and the press cover; and springs are arranged on the front core tire and the back core tire. The tool has the benefits of being simple in use, convenient and accurate, reducing the error, saving the time and improving the detection efficiency.

Description

Each hole position check tool of exhaust manifold supercharging flange

Technical field

The utility model belongs to the enmgine exhaust technical field, is specifically related to a kind of instruments of inspection that detects each hole location of exhaust manifold supercharging flange.

Background technology

ERG is the very important device of engine, part waste gas is drawn from gas outlet, enter exhaust manifold by ERG, reallocation burns for each cylinder, reduced the discharge capacity of oxides of nitrogen in the engine exhaust pollutant effectively, the exhaust manifold on the motor car engine has also play a part very important in this process.

The interface of enmgine exhaust and engine, the performance of direct relation engine and stability, if both are in conjunction with undertighten, all can fall the task of improving its combination on the sealing mat to a great extent, even the connecting screw reinforcing is big again, also can't resolve the immediate problem that rigid contact does not closely bring, otherwise it is big exhaust sound to occur, listen uncomfortable, the unable such consequence of engine.

To each hole location of exhaust manifold supercharging flange be detected when producing exhaust manifold, compare when promptly the physical location in each hole of supercharging flange and size are with design whether in the deviation range of permission.At present detection method is: when air flue is one all with the position degree of maximum solid state measurement machining hole and air flue, shortcoming: the range estimation error is big, the anchor point that requires according to drawing does not detect, and does not accomplish that each product all measures in Design Orientation point/centralized positioning.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of and can addresses the above problem, and reduces error, and can conveniently detect the cubing of each hole location of exhaust manifold supercharging flange.

The utility model can be realized like this, each hole position check tool of a kind of exhaust manifold supercharging flange, comprise check-out console, check-out console is provided with test pin, left and right sides core tire and front and back core tire, be provided with screw mandrel in the middle of left and right sides core tire and the front and back core tire, be provided with gland above the core tire of the left and right sides, be provided with spring between left and right sides core tire and the gland, be provided with spring above the core tire of front and back.

The beneficial effects of the utility model are: the utility model uses simple, and is accurately convenient, reduced error, saved the time, improved detection efficiency.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the A-A cut-open view of Fig. 2.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described:

As Fig. 1, Fig. 2, shown in Figure 3: each hole position check tool of a kind of exhaust manifold supercharging flange, comprise check-out console 1, check-out console 1 is provided with four test pins 2, left and right sides core tire 8 and front and back core tire 6, left and right sides core tire 8 is connected with the front and back core tire 6 middle screw mandrels 4 that lean on, be provided with gland 5 above the left and right sides core tire 8, be provided with spring 3 between left and right sides core tire 8 and the gland 5, be provided with spring 7 above the front and back core tire 6.Left and right sides core tire 8 decide by drawing exhaust manifold supercharging flange air flue about to front and back that, front and back core tire 6 is decided exhaust manifold supercharging flange air flue by drawing to, left and right sides core tire 8 all has tapering with front and back core tire 6.

During detection, exhaust manifold supercharging flange is put on the check-out console, exhaust manifold supercharging flange air flue center is corresponding with screw mandrel 4 centers, four holes of exhaust manifold supercharging flange correspond to the position of four test pins 2 and place, if four hole fits of four test pins 2 and exhaust manifold supercharging flange, each hole location that exhaust manifold supercharging flange is described meets the requirements, if be not suitable for illustrating that each hole location is undesirable.

Explanation is at last; above embodiment only is used to the technical solution of the utility model is described and is unrestricted; other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement; only otherwise break away from the spirit and scope of technical solutions of the utility model, all should cover in the protection claimed range of the present utility model.

Claims

1. each hole position check tool of exhaust manifold supercharging flange, it is characterized in that: it comprises check-out console, check-out console is provided with test pin, left and right sides core tire and front and back core tire, be provided with screw mandrel in the middle of described left and right sides core tire and the front and back core tire, be provided with gland above the core tire of the described left and right sides, be provided with spring between described left and right sides core tire and the gland, be provided with spring above the core tire of described front and back.
