Description

Technical Field

[0001] The utility model relates to the technical field of seat ring detection, and more specifically, to a measuring device for the K-cylinder head guide seat ring. Background Art

[0002] The K-cylinder head guide seat ring is an important component of the engine. Its machining accuracy has a crucial impact on the performance of the vehicle. Its main function is to guide the movement of the valve and ensure the sealing between the valve and the seat ring, thereby ensuring the normal operation of the engine. During the machining process, it is necessary to strictly control indicators such as the position degree, cylindricity, and central hole diameter of the guide seat ring to ensure that it meets the requirements of high-performance engines. Therefore, during the machining process, a measuring device is required to measure the K-cylinder head guide seat ring.

[0003] As disclosed in a Chinese patent: A device for measuring the taper angle of the seat ring of a cylinder head, application number: CN202322654041.X, which includes a base and an X-axis micrometer and a Y-axis micrometer arranged on the base through a connecting member. An X-axis lever is installed on the base through a connecting member. The measuring head of the X-axis micrometer is in contact with one end of the X-axis lever, and the other end of the X-axis lever can be in surface contact with the seat ring of the cylinder head to be measured during measurement. The measuring head of the Y-axis micrometer is on the valve line of the seat ring of the cylinder head to be measured. A guiding component is also provided on the base. The device for measuring the taper angle of the seat ring of a cylinder head disclosed in this application adopts a self-made seat ring taper angle measuring device with a lever structure. The Y-axis micrometer is vertically arranged. During the measurement process, the measuring head is always pressed on the valve line of the cylinder head seat ring to ensure the accuracy of the measurement. The device realizes the stable up and down movement of the whole measuring frame through the clearance fit between the guide rod seat and the guide hole. This device has the characteristics of convenient operation and high measurement accuracy.

[0004] However, in the above technical solution, most of the measuring devices on the market today use a two-point measurement method to measure the central hole diameter of the K-cylinder head guide seat ring. Although this method can measure the data of the central hole diameter of the K-cylinder head guide seat ring, its inherent limitations cannot be ignored. Specifically, the two-point measurement method only measures two specific points of the hole diameter and does not fully cover the entire hole wall. This means that if there are defects such as depressions or protrusions in other parts of the inner wall of the central hole of the K-cylinder head guide seat ring, this method will not be able to effectively detect them, resulting in a significant reduction in the accuracy of the measurement results, which may lead to misjudgment of the quality of the K-cylinder head guide seat ring and relatively low accuracy. Summary of the Utility Model

[0005] The main purpose of the present utility model is to provide a measuring device for the K cylinder head duct seat ring, which can effectively solve the problem that most of the measuring devices on the current market in the background technology use a two-point measurement method to measure the center hole diameter of the K cylinder head duct seat ring. Although this method can measure the data of the center hole diameter of the K cylinder head duct seat ring, its inherent limitations cannot be ignored. Specifically, the two-point measurement method only measures two specific points of the hole diameter and fails to comprehensively cover the entire hole wall. This means that if there are defects such as depressions or protrusions in other parts of the inner wall of the center hole of the K cylinder head duct seat ring, this method will not be able to effectively detect them, resulting in a significant reduction in the accuracy of the measurement results, which may lead to misjudgment of the quality of the K cylinder head duct seat ring and relatively low accuracy.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0007] The measuring device for the K cylinder head duct seat ring includes a base, on which a touch screen and a two-way moving table are arranged. A first motor is fixedly installed on the two-way moving table, a connecting plate is arranged on the first motor, two first sliders are slidably arranged on the connecting plate, a threaded column is threaded on the first slider, an induction component is fixedly arranged on the side of the first slider close to the base, a first bevel gear is arranged on the threaded column, a second bevel gear is meshed between the two first bevel gears, a second motor is arranged on the second bevel gear, a scale is arranged on one side of the connecting plate, an index is arranged on the side of the induction component close to the scale, and a fixture is fixedly arranged on one side of the base.

[0008] Preferably, the threaded column is rotationally connected to the connecting plate, and the second motor is fixedly installed on the connecting plate.

[0009] Preferably, the induction component includes a component base, a chute is arranged on the component base, a groove is arranged on one side of the chute, and a first energized piece is fixedly arranged on the inner wall of the groove.

[0010] Preferably, a second slider is slidably arranged in the chute, a spring is fixedly arranged on one side of the second slider, a semi-circular probe is fixedly arranged on the side of the second slider away from the spring, a current inductor is fixedly arranged on the second slider, and a second energized piece is fixedly arranged on the side of the current inductor close to the first energized piece.

[0011] Preferably, the spring is fixedly connected to the component base.

[0012] Preferably, the semi-circular probe is located outside the chute.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] (1) When the utility model is in use, the induction component is moved to the center hole of the seat ring through the bidirectional moving platform. Then, the inner wall of the center hole of the seat ring presses the semi-circular probe, causing the spring to deform, so that the second energized sheet changes from a separated state to a fitting state with the first energized sheet. When the second energized sheet fits with the first energized sheet, the current inductor can detect current on the second energized sheet. Then, the component base stops moving, and the radius of the center hole of the seat ring is measured and read through the scale and the indicator. Subsequently, the connecting plate is rotated by the first motor, and the connecting plate drives the induction component to slowly rotate through the first slider, comprehensively measuring the inner wall of the center hole of the seat ring, and using the touch screen to monitor the data of the current inductor. If there are recesses or protrusions on the inner wall of the center hole of the seat ring, the spring rebounds, causing the second energized sheet to change from fitting to separated from the first energized sheet. At this time, the current inductor cannot detect current on the first energized sheet, thereby detecting that there are defects on the inner wall of the center hole of the seat ring, and the inner wall of the center hole of the seat ring can be comprehensively measured, increasing the measurement accuracy.

Detailed Embodiment

[0020] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 3 shown, the K-cylinder head guide seat ring measuring device includes a base 1, a touch screen 2 and a bidirectional moving table 3 are arranged on the base 1, a first motor 4 is fixedly installed on the bidirectional moving table 3, a connecting plate 5 is arranged on the first motor 4, two first sliders 6 are slidably arranged on the connecting plate 5, a threaded column 7 is arranged on the first slider 6 in a threaded manner, an induction component 8 is fixedly arranged on one side of the first slider 6 close to the base 1, a first bevel gear 9 is arranged on the threaded column 7, a second bevel gear 10 is meshed between the two first bevel gears 9, a second motor 11 is arranged on the second bevel gear 10, a scale 12 is arranged on one side of the connecting plate 5, an index 13 is arranged on one side of the induction component 8 close to the scale 12, and a clamp 14 is fixedly arranged on one side of the base 1.

[0022] As Figure 4 shown, in another embodiment of the present utility model, the induction component 8 includes a component base 801, a chute 802 is arranged on the component base 801, a groove 803 is arranged on one side of the chute 802, and a first energized piece 804 is fixedly arranged on the inner wall of the groove 803;

[0023] A second slider 805 is slidably arranged in the chute 802, a spring 806 is fixedly arranged on one side of the second slider 805, a semi-circular probe 807 is fixedly arranged on the side of the second slider 805 away from the spring 806, a current inductor 808 is fixedly arranged on the second slider 805, and a second energized piece 809 is fixedly arranged on the side of the current inductor 808 close to the first energized piece 804;

[0024] When it is necessary to measure the diameter of the center hole of the seat ring, first move the induction component 8 into the center hole of the seat ring, and then make the component base 801 close to the inner wall of the center hole of the seat ring, so that the inner wall of the center hole of the seat ring presses the semi-circular probe 807. The semi-circular probe 807 moves into the chute 802. The semi-circular probe 807 drives the second slider 805 to move, the spring 806 deforms, and the second slider 805 drives the second energized piece 809 to move through the current inductor 808, so that the state between the second energized piece 809 and the first energized piece 804 changes from a separated state to a fitting state. When the second energized piece 809 is in contact with the first energized piece 804, the current inductor 808 will detect current on the second energized piece 809, and then the component base 801 stops moving, so that the second energized piece 809 and the first energized piece 804 remain in a fitting state. Subsequently, the induction component 8 is slowly rotated to comprehensively measure the inner wall of the center hole of the seat ring. If there are recesses or protrusions on the inner wall of the center hole of the seat ring, the inner wall of the center hole of the seat ring will temporarily not press the semi-circular probe 807, the spring 806 rebounds, causing the second slider 805 to move, so that the second energized piece 809 and the first energized piece 804 change from being in contact to being separated. At this time, the current inductor 808 cannot detect current on the first energized piece 804, thereby detecting that there are defects on the inner wall of the center hole of the seat ring.

[0025] The working principle of this K-cylinder head guide seat ring measuring device:

[0026] In use, first, the seat ring is clamped and fixed by the fixture 14. Then, the induction component 8 is moved to the center hole of the seat ring through the bidirectional moving table 3. Then, the first motor 4 is started. The first motor 4 drives the second bevel gear 10 to rotate. The second bevel gear 10 drives two first bevel gears 9 to rotate. The first bevel gear 9 moves the first slider 6 towards the inner wall of the center hole of the seat ring through the threaded column 7. The first slider 6 drives the component base 801 to move, so that the inner wall of the center hole of the seat ring presses against the semi-circular probe 807. The semi-circular probe 807 drives the second slider 805 to move, and the spring 806 deforms, so that the second energized piece 809 and the first energized piece 804 change from the separated state to the fitting state. When the second energized piece 809 is in contact with the first energized piece 804, the current inductor 808 will detect current on the second energized piece 809. Then, the component base 801 stops moving. The diameter of the center hole of the seat ring is measured and read through the scale 12 and the index 13. Subsequently, the connecting plate 5 is rotated by the first motor 4. The connecting plate 5 drives the induction component 8 to rotate slowly through the first slider 6, and the inner wall of the center hole of the seat ring is comprehensively measured. The data of the current inductor 808 is monitored by using the touch screen 2. If there are recesses or protrusions on the inner wall of the center hole of the seat ring, the spring 806 rebounds, so that the second energized piece 809 and the first energized piece 804 change from being in contact to being separated. At this time, the current inductor 808 cannot detect current on the first energized piece 804, so as to detect that there are defects on the inner wall of the center hole of the seat ring, and the inner wall of the center hole of the seat ring can be comprehensively measured to improve the measurement accuracy.

[0027] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention are still within the protection scope of the present invention.
