[0002] V-type valve refers to a valve structure in which the intake valve and exhaust valve have a certain angle relative to the vertical line. This design is often used in engines to optimize the airflow path and improve combustion efficiency. Traditional measurement tools are usually suitable for measuring the valve sinking amount of conventional cylinder heads, but for V-type valves, these tools often cannot provide accurate measurement results.

[0003] In the prior art, the valve sinking amount of a conventional cylinder head is usually measured using a bridge gauge tool. Figure 1 As shown in the figure, this tooling includes a bridge gauge seat, a micrometer and a corresponding supporting structure. The bridge gauge seat is usually fixed on the cylinder head, and the micrometer is used to measure the valve sinking amount. Since this measuring tool cannot be used to measure the sinking amount of V-type valves, when it comes to V-type valves, the existing technology usually requires the use of three-coordinate measuring equipment, which is not only time-consuming and labor-intensive, but also costly.

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs.

[0030] Glossary:

[0031] V-type valve: refers to a structural form of valve, mainly used in V-type engines. In a V-type engine, the valves are arranged on both sides of the engine. The V-type valve is mainly composed of the valve head, valve stem and valve spring. The valve head is connected to the valve stem and can move up and down. The valve spring is used to ensure that the valve can fit tightly on the valve seat when closed. When the engine is in the intake stroke, the intake valve opens, the exhaust valve closes, the piston in the cylinder moves from top to bottom, and the channel formed by the intake valve allows the mixture to enter the cylinder. When the engine is in the exhaust stroke, the exhaust valve opens, the intake valve closes, the piston in the cylinder moves from bottom to top, and the channel formed by the exhaust valve allows the exhaust gas to be discharged from the cylinder.

[0032] As introduced in the background technology, the main problems existing in the prior art include: conventional bridge gauge tooling cannot adapt to the special structure of the V-type valve, resulting in the inability to accurately measure the sinking amount. Although the measurement problem can be solved by using a three-coordinate measuring device, the process is cumbersome, inefficient, and costly. In order to solve the above technical problems, the utility model proposes an engine V-type valve sinking amount measuring tool, which has a simple structure, is easy to operate, and can accurately and efficiently measure the sinking amount of the V-type valve. Through a special sliding structure and positioning mechanism, the tool can realize the precise measurement of the sinking amount of the valve at any position, while avoiding the complexity and high cost of using a three-coordinate measuring device, which is of great significance for improving the accuracy of engine maintenance and manufacturing.

[0033] like Figure 2 As shown, the engine V-valve sinking measurement tool includes: a bridge meter seat 1, a slide rail 4, a slider 7 and a meter head 2; Figure 4 As shown, a first slide groove 11 is provided on the bottom side of the left end of the bridge meter seat 1. The first slide groove 11 is mounted on the slide rail 4 and can slide along the slide rail 4. The slide rail 4 is used to be fixed on the engine. A second slide groove 12 is provided on the right end of the bridge meter seat 1. The second slide groove 12 is arranged obliquely relative to the top surface of the slide rail 4 and is parallel to the upper surface of the V-shaped valve 8 (as shown in FIG. Figure 5 As shown), the second slide groove 12 is perpendicular to the projection of the first slide groove 11 on the horizontal plane; the header 2 is fixed on the slider 7, the slider 7 is installed on the first slide groove 11 and can slide along the first slide groove 11, and the measuring rod of the header 2 is perpendicular to the upper surface of the V-shaped valve 8.

[0034] The slide rail 4 is fixed on the engine to ensure the stability of the measuring tool. The first slide groove 11 is opened on the bottom side of one end of the bridge meter seat 1, and the slide groove cooperates with the slide rail 4 to allow the bridge meter seat 1 to slide along the slide rail 4. The other end of the bridge meter seat 1 is provided with a second slide groove 12, which is arranged obliquely with the top surface of the slide rail 4 and is parallel to the upper surface of the V-shaped valve 8, so as to achieve accurate measurement of the valve sinking amount. The meter head 2 is fixed on the slider 7, and the slider 7 slides along the first slide groove 11. The measuring rod of the meter head 2 is perpendicular to the upper surface of the V-shaped valve 8 for measurement.

[0035] When using, Figure 5 As shown, first fix the slide rail 4 on the engine cylinder head assembly, then slide the bridge meter seat 1 along the slide rail 4 to an appropriate position through the first slide groove 11, move the slider 7 along the second slide groove 12 to the position of the upper surface of the V-type valve 8, and measure the sinking amount through the meter head 2. Through the cooperation of the above two vertical slide grooves, the sinking amount of the V-type valve 8 at any position can be measured, and the operation is convenient. At the same time, it avoids the complexity and high cost of using three-coordinate measurement of the sinking amount of the V-type valve 8, and can perform fast and accurate measurement. Compared with complex three-coordinate measurement equipment, it improves measurement efficiency, saves time and is efficient.

[0036] The sliding fit of the slide groove makes the sliding fit contact area larger, and compared with the bending method of the support rod, the shaking is small, the measurement accuracy is more accurate, and the operation is convenient.

[0037] The two vertical slides are moved and positioned to ensure that the bridge meter base 1 and the meter head 2 can only move along the length direction of their respective slides, reducing the movement and deflection of the tooling in other directions and making the measurement more accurate.

[0038] like Figure 4 As shown, the bridge table seat 1 includes a sliding section and a supporting section. The longitudinal section of the sliding section is rectangular, the first sliding groove 11 is arranged on the bottom surface of the sliding section, the cross section of the supporting section is a right-angled trapezoid, and the second sliding groove 12 is arranged on the supporting section.

[0039] The design of the sliding section and the supporting section improves the stability of the structure, can withstand greater measurement reaction force, and improves the reliability of the measuring tool. It also enables the bridge meter seat 1 to be stably positioned on the engine, while the inclined arrangement of the second slide groove 12 allows the slider 7 to slide along it to meet the measurement requirements of the V-type valve 8.

[0040] like Figure 4 As shown, the first slide groove 11 is rectangular, and the second slide groove 12 is a transverse convex shape. Figure 3 As shown, the table header 2 is installed at one end of the slider 7, and grooves are provided on the upper and lower surfaces of the other end, and the grooves are embedded in the second slide groove 12 for guidance.

[0041] The first slide groove 11 is rectangular, providing a stable sliding guide. The second slide groove 12 is a transverse convex shape, which increases the stability of the slider 7. The grooves set on the upper and lower surfaces of the slider 7 are embedded in the second slide groove 12 to achieve precise guidance. During the measurement process, the slider 7 slides along the second slide groove 12 through the groove, and the measuring rod of the meter head 2 vertically contacts the upper surface of the V-shaped valve 8 to measure the sinking amount. The design of the convex slide groove and the groove improves the guiding accuracy of the slider 7 and ensures the accuracy of the measurement.

[0042] like Figure 4 As shown, the second chute 12 is open at one end away from the first chute 11. By designing the end of the second chute 12 away from the first chute 11 to be open, this design facilitates the installation and removal of the slider 7 and improves the maintainability of the measuring tool.

[0043] like Figure 2 As shown, a baffle plate 3 is detachably mounted on one end of the bridge meter seat 1, and the baffle plate 3 is located at the end of the second slide groove 12 with an opening. This design can prevent the slider 7 from sliding out of the second slide groove 12, thereby improving the safety of the measuring tool. The detachable design of the baffle plate 3 allows the baffle plate 3 to be flexibly installed or removed, thereby increasing the maintainability of the tool.

[0044] like Figure 1 As shown, at least two positioning holes are provided on the slide rail 4, and positioning pins 5 are installed in the positioning holes. The slide rail 4 is fixed to the cylinder head assembly of the engine through the positioning pins 5. The positioning pins 5 are used to fix the slide rail 4 to the engine cylinder head assembly, thereby ensuring the stability of the measuring tool. When installing the measuring tool, the positioning pins 5 are inserted into the corresponding holes of the cylinder head assembly, and the positioning pins 5 are used to fix the slide rail 4 so as to ensure that the slide rail 4 will not be displaced during the measurement process. The use of the positioning pins 5 improves the positioning accuracy of the measuring tool and reduces the measurement error caused by the movement of the slide rail 4. The upper end surface of the positioning pin 5 is designed to be no higher than the top surface of the slide rail 4, thereby avoiding unnecessary interference or damage to the engine cylinder head during the measurement process.

[0045] like Figure 2 As shown, the measuring tool further includes a locking member 6, a locking groove 13 is provided on the upper portion of the support section of the bridge meter seat 1, the locking groove 13 penetrates the second slide groove 12, a threaded hole is provided on the slider 7, and the locking member 6 passes through the locking groove 13 and is installed on the threaded hole of the slider 7. When in use, the position of the slider 7 on the bridge meter seat 1 can be fixed by rotating the locking member 6 to ensure the stability of the measurement. The use of the locking member 6 provides a fast and stable locking mechanism, which is convenient for the user to quickly adjust the position of the slider 7 during the measurement process.

[0046] The locking member 6 can be a butterfly bolt, such as Figure 2As shown, the butterfly bolt has a simple structure and is easy to operate, and is suitable for fast locking and releasing. The use of the butterfly bolt simplifies the locking and adjustment process and improves work efficiency.

[0047] The meter head 2 is a micrometer, which has high precision and readability and is suitable for fine measurement. The micrometer is fixed on the slider 7, and its measuring rod vertically contacts the upper surface of the V-type valve 8 to measure the sinking amount. The use of the micrometer ensures the high precision of the measurement result and meets the strict requirements of the engine V-type valve sinking amount measurement.

[0048] How to use this measuring tool:

[0049] Place the slide rail 4 on the cylinder head assembly through the positioning pin 5;

[0050] By means of the sliding fit between the bridge meter seat 1 and the slide rail 4, the bridge meter seat 1 is moved along the slide rail 4 to the valve position;

[0051] By utilizing the sliding fit between the slider 7 and the bridge gauge seat 1, the dial gauge is moved to the upper surface of the valve;

[0052] Fix the slider 7 and the dial indicator at the desired position by butterfly bolts;

[0053] Read the dial indicator to get the valve sinking amount.

[0054] Specifically, when measuring, the slide rail 4 is placed on the cylinder head assembly through the positioning pin 5, the micrometer is fixed on the slider 7, the slider 7 and the special groove between the bridge meter seat 1 are slidably matched, and the sliding line of the slider 7 is parallel to the upper surface of the valve. The slider 7 and the micrometer can be fixed at any position in the groove by tightening the butterfly bolt, and the bridge meter seat 1 and the slide rail 4 are also slidably matched. Through the sliding match between the bridge meter seat 1 and the slide rail 4, and the sliding match between the slider 7 and the bridge meter seat 1, the bridge meter can measure the sinking amount of any position of the valve.

[0055] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
