Description

Technical Field

[0001] This utility model relates to the field of valve sinking measurement technology, and in particular to an auxiliary tooling and measuring structure for valve sinking measurement. Background Technology

[0002] During engine validation on the test bench, valve deflection needs to be measured according to different test requirements.

[0003] For valves that are not installed at a 90-degree angle, their unique angle makes manual measurement impossible, requiring a coordinate measuring machine (CMM) for inspection. This measurement process necessitates not only round-trip delivery but also the arrangement of a specialized CMM.

[0004] Measuring the deflection of valves that are not installed at a 90-degree angle is labor-intensive and costly. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an auxiliary tooling and measuring structure for measuring valve sinking.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The first aspect of this utility model provides an auxiliary tooling for measuring valve deflection, comprising:

[0008] A base for detachably fixing to the cylinder head of the valve to be tested;

[0009] A rotating plate, wherein the rotating plate is provided with a first fixing hole for fixing a depth gauge;

[0010] Mounting plate, the mounting plate is fixed on the base, the rotating plate is rotatably connected to the mounting plate and the mounting plate is provided with an arc-shaped adjustment hole whose center coincides with the rotating axis of the rotating plate;

[0011] A locking bolt is attached to the rotating plate to lock the rotating plate to the adjusting hole.

[0012] The second aspect of this utility model provides a valve deflection measurement structure, including a cylinder head for measuring the valve to be tested and a depth gauge for measuring the valve deflection, and also includes an auxiliary tooling for measuring valve deflection as described in the first aspect, wherein the base is fixed on the cylinder head and the depth gauge is placed on the first fixing hole.

[0013] This utility model has the following advantages:

[0014] The auxiliary tooling of this solution allows for the adjustment of the angle between the rotating plate and the base so that the rotating plate is perpendicular to the valve. This allows the depth gauge to be placed in the first fixed hole of the rotating plate for measurement. The tooling is not only simple in structure but also allows for arbitrary adjustment of the angle, meeting the measurement needs of different intake and exhaust valve angles and reducing workload and measurement costs.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The first aspect of this utility model discloses an auxiliary tooling for measuring valve deflection, which is used to assist in measuring valve deflection. Specifically, as shown... Figure 1 As shown, the auxiliary tooling includes a base 1, a rotating plate 3, a mounting plate 2, and locking bolts 4.

[0027] The base 1 is used for detachable fixing to the cylinder head of the valve to be tested. For example, the base can be connected and fixed to the cylinder head by bolts. Exemplarily, to avoid the base affecting the measurement and to facilitate fixing, the base 1 includes a base body and a fixing end connected to the base body, wherein the fixing end is provided with a second fixing hole 11. Figure 1 As shown, the base 1 is T-shaped, which facilitates the setting of the mounting plate 2 and the installation of the base on the cylinder head, while also reducing the impact on depth gauge measurement.

[0028] The rotating plate 3 is provided with a first fixing hole 31 for fixing the depth gauge. During measurement, the depth gauge can be installed in the first fixing hole.

[0029] Mounting plate 2 is fixed on base 1. Rotating plate 3 is rotatably connected to mounting plate 2 and mounting plate 2 is provided with arc-shaped adjustment hole 21, wherein the center of the adjustment hole 21 coincides with the rotation axis of rotating plate 3.

[0030] The locking bolt 4 is connected to the rotating plate 3 to lock the rotating plate 3 with the adjusting hole 21.

[0031] Using the above structure, during measurement, first remove other related components from the cylinder head, then install the base plate in the corresponding position and fix it to the cylinder head. Loosen the locking bolt 4, rotate the rotating plate 3 to a suitable angle, i.e., make the rotating plate 3 perpendicular to the valve to be tested, and tighten the locking bolt 4 to lock the rotating plate 3 with the adjusting hole 21, i.e., fix the rotating plate 3 with the mounting plate 2. Then, place the depth gauge in the first fixing hole for measurement. This eliminates the need to send the cylinder head with the valve installed to the coordinate measuring machine for measurement, saving on the round-trip delivery process and the coordinate measuring machine measurement process, reducing the workload of the operators, and also saving costs.

[0032] Mounting plate 2 can be set with only one or two. To improve the stability of rotating plate 3 and the accuracy of measurement, it is preferable to use... Figure 1 The structure of the two mounting plates 2 shown is such that the two mounting plates 2 are respectively set on both sides of the rotating plate 3.

[0033] To further improve the stability of the auxiliary tooling structure, the mounting plate 2 and the base 1 are preferably integrated.

[0034] The mounting plate 2 and the rotating plate 3 are rotatably connected, which can be achieved in many ways. For ease of assembly, the rotatable connection is achieved through a pin 5.

[0035] To facilitate the adjustment of the angle of the rotating plate relative to the base 1, the mounting plate 2 is further provided with an angle mark for indicating the angle of the rotating plate relative to the base 1.

[0036] The second aspect of this utility model discloses a valve deflection measurement structure, such as... Figures 2 to 4 As shown, the device includes a cylinder head 6 with a valve to be tested and a depth gauge 7 for detecting the valve deflection. It also includes an auxiliary tooling for measuring valve deflection as described in the first aspect and any possible design thereof. The base 1 is fixed on the cylinder head, and the depth gauge is placed on the first fixing hole 31.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
