DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0023] Referring to the accompanying drawings, a measuring mechanism for measuring the width of a valve seat ring includes: a positioning seat 1, a support seat 2, a slider 3, an adjusting screw 4, a pressure spring 41, a clamping block, a magnifying glass body 6 and a light source body 7.

[0024] Positioning base 1 is positioned below support base 2 and connects to the catheter hole of an external device through positioning base 1. Positioning base 1 includes a positioning block 11 and a guide rod 12. Guide rod 12 is positioned below positioning block 11, which is fixedly connected to support base 2. Positioning block 11 is used to connect to support base 2, and guide rod 12 is used to accurately position and connect with the catheter hole of the external device.

[0025] In order to closely fit the width of the valve seat ring to be measured, the cross-sectional area of ​​the lower end of the positioning block 11 can be set to be smaller than the cross-sectional area of ​​the upper end of the positioning block 11, that is, the bottom surface of the positioning seat 1 contacts the workpiece in an inverted cone structure.

[0026] The support base 2 is configured as a hollow structure, with a chute and a receiving cavity provided therein. The chute and the receiving cavity may be connected or disconnected, and may be two independent spaces. The chute is used to accommodate the slider 3, and the receiving cavity is used to accommodate the light source body 7.

[0027] Slider 3 is disposed within the chute of support base 2 and is slidably connected to support base 2, allowing it to slide up and down within the chute. Support base 2 is provided with a threaded hole, through which an adjustment screw 4 is threadedly connected. Adjustment screw 4 passes through the threaded hole and is fixedly connected to slider 3. Sliding slider 3 within the chute is achieved by screwing adjustment screw 4 in and out of support base 2.

[0028] To better secure the adjusting screw 4 during its rotation, the measuring mechanism further includes a mounting block 9. The mounting block 9 is disposed at the upper end of the support base 2. The adjusting screw 4 extends through the mounting block 9 into the slider 3 of the support base 2. The mounting block also serves as a guide during the rotation of the adjusting screw 4.

[0029] The mounting block 9 further comprises a limit screw 91, which is provided with a transverse limit hole, through which the limit screw 91 passes to connect with the adjusting screw 4. When the adjusting screw 4 is rotated to a suitable position, the limit screw 91 can be tightened to limit it to the position and fix it immovably.

[0030] A pressure spring 41 is mounted on the adjusting screw 4 and connected to the slider 3. The pressure spring 41 exerts a constant downward force, thereby eliminating any up-and-down movement of the slider 3 within the support 2. If the measuring mechanism also includes a mounting block 9, one end of the pressure spring 41 can be mounted on the mounting block 9, and the other end of the pressure spring 41 can be mounted on the slider 3.

[0031] The clamping block is connected to the slider 3, and the magnifying glass body 6 is arranged in the clamping block. The magnifying glass body 6 passes through the inside of the positioning seat 1 after being fixed by the clamping block. An angle is set between the axis of the magnifying glass body 6 and the axis of the support seat 2. The clamping block includes a fastening block 51 and a connecting block 52. The fastening block 51 is connected to the slider 3 through the connecting block 52, and the connecting block 52 is connected to the slider 3 through a connecting screw 521. The fastening block 51 is set as an annular structure, similar to a clamp structure. The annular structure of the clamping block is divided into two and broken. The magnifying glass body 6 is conveniently clamped or removed by tightening the screws. At the same time, it can be suitable for clamping magnifying glass bodies 6 of different models. The magnifying glass body 6 can be a conventional industrial magnifying glass in the prior art, such as an industrial magnifying glass with model AD-86C.

[0032] The light source body 7 is arranged in the receiving cavity of the support seat 2, and the light source direction of the light source body 7 is aligned with the valve seat ring. The light source body 7 can be a conventional pen-type flashlight in the prior art, such as the tank007-UV02 pen-type flashlight model.

[0033] In order to better fix the light source body 7, a sleeve 8 can be provided in the receiving cavity of the support base 2. The sleeve 8 is sleeved on the light source body 7 and connected to the support base 2 via a fixing screw 81. After the fixing screw 81 is tightened, the light source body 7 is squeezed and fixed in the support base 2 by the sleeve 8. The material of the sleeve 8 can be selected as copper, which can better protect the light source body 7.

[0034] During the actual measurement process, place the positioning seat 1 into the conduit hole of the cylinder head. After it is positioned securely, place the conical surface structure at the upper end of the positioning seat 1 close to the position of the valve seat ring band to be measured. Turn on the light source of the light source body 7, turn the adjustment screw 4, and adjust the lens of the magnifying glass body 6 to the appropriate position of the cylinder head intake and exhaust valve seat ring band width. When the lens of the magnifying glass body 6 reaches the measuring surface, the mounting block 9 and the support seat 2, as well as the support seat 2 and the positioning seat 1, are fixedly connected by screws. Turn the focal length knob attached to the magnifying glass body 6 to adjust the focal length of the magnifying glass body 6 so that the valve seat ring band can be clearly seen. Use the scale inside the lens of the magnifying glass body 6 to measure the intake and exhaust valve seat ring band width. The measurement result depends on whether the measured value is within the measured tolerance range. The measured value is considered qualified if it is within the measured tolerance range, and it is considered unqualified if the measured value exceeds the tolerance range.

[0035] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
