Description

Technical Field

[0001] This utility model relates to the field of valve machining measurement technology, specifically a valve machining dimension measuring device for rapid calibration. Background Technology

[0002] Valve is a crucial component of an internal combustion engine, playing a key role in the engine's intake and exhaust processes. Valve is generally divided into intake valves and exhaust valves, which respectively control the entry of fresh air or air-fuel mixture into the combustion chamber and the exit of exhaust gases from the combustion chamber. Valve performance directly affects engine efficiency, power output, and emissions levels; therefore, valve manufacturing requires extremely high precision and specialized measuring equipment to ensure compliance with design specifications. Valve dimensional measurements mainly include head diameter, stem diameter, length, and angle.

[0003] Existing valve machining dimension measuring devices typically employ non-contact vision measurement technology, utilizing image processing and analysis to acquire object size, shape, and other features. A camera captures valve images, and appropriate light sources enhance the contrast of specific features. To measure the side dimensions and angles of the valve, it is necessary to rotate the valve. Therefore, precise positioning of the valve and rotating components is required. Currently, valve positioning requires adjustment of the center position; otherwise, the valve rotation will deviate, affecting the effectiveness of the vision measurement. Utility Model Content

[0004] The purpose of this invention is to provide a valve machining dimension measuring device for rapid calibration, in order to solve the problem mentioned in the background art that current valve machining dimension measuring devices on the market require valve rotation to measure the side dimensions and angles of the valve. Therefore, precise positioning of the valve and the rotating component is required. Currently, when positioning the valve, the center position needs to be adjusted, otherwise the valve rotation will be offset, affecting the visual measurement effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a valve machining dimension measuring device for rapid calibration, comprising a valve dimension measuring device body and a valve. The valve dimension measuring device body is provided with a support plate, and a housing is connected to the upper end of the support plate. A first visual measuring mechanism and a second visual measuring mechanism are respectively installed on one side and the top of the housing. A supplementary light is installed on the sides of the first visual measuring mechanism and the second visual measuring mechanism. A rotating disk is snapped onto the support plate, and a hollow transmission gear is connected to the bottom of the rotating disk. A stabilizing bracket is connected to the bottom of the support plate, and a servo lifting hydraulic cylinder and a rotary drive mechanism are installed on the stabilizing bracket. A calibration positioning rod is connected to the movable end of the servo lifting hydraulic cylinder, and the calibration positioning rod is engaged with the transmission gear. A drive gear is fixed to the output end of the rotary drive mechanism, and the drive gear meshes with the transmission gear.

[0006] Preferably, the upper end of the support plate is fixed with an upper sealing plate by bolts, and the rotating disk is movably engaged between the support plate and the upper sealing plate.

[0007] Preferably, the rotating disk has a through hole in the middle, and the size of the through hole is larger than the diameter of the calibration positioning rod.

[0008] Preferably, the calibration positioning rod is inserted into the valve, and the valve is placed on the rotating disk.

[0009] Preferably, the top side of the calibration positioning rod is inclined, and there is a clearance fit between the calibration positioning rod and the transmission gear.

[0010] Preferably, drag-reducing balls are evenly spaced and movably embedded above the side of the calibration positioning rod, and the drag-reducing balls roll into contact with the inner wall of the valve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This rapid calibration valve machining dimension measuring device supports and rotates the valve through a rotating disk, and a liftable calibration positioning rod is set inside the rotating disk, enabling precise positioning during valve measurement. The device has a hollow transmission gear fixed at the bottom of the rotating disk, allowing the calibration positioning rod to move up and down within the gear while avoiding interference with the rotation of the rotating disk.

Furthermore, the calibration positioning rod remains unaffected as the valve rotates with the rotating disk. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a valve machining dimension measuring device for rapid calibration, including a valve dimension measuring device body 1 and a valve 7. A support plate 2 is provided on the valve dimension measuring device body 1, and a housing 6 is connected to the upper end of the support plate 2. A first visual measuring mechanism 10 and a second visual measuring mechanism 12 are respectively installed on one side and the top of the housing 6. A supplementary light 11 is installed on the sides of the first visual measuring mechanism 10 and the second visual measuring mechanism 12. A rotating disk 3 is snapped onto the support plate 2, and an upper sealing plate 8 is fixed to the upper end of the support plate 2 by bolts. The rotating disk 3 is movably snapped between the support plate 2 and the upper sealing plate 8. This structure allows the rotating disk 3 to move between the support plate 2 and the upper sealing plate 8. The upper sealing plate 8 is positioned for smooth rotation. Ball bearings are installed between the rotating disk 3, the support plate 2, and the upper sealing plate 8 to reduce rotational resistance and ensure smooth rotation. A hollow transmission gear 301 is connected to the bottom of the rotating disk 3, and a stable bracket 9 is connected to the bottom of the support plate 2. A servo lifting hydraulic cylinder 4 and a rotation drive mechanism 5 are installed on the stable bracket 9. The movable end of the servo lifting hydraulic cylinder 4 is connected to a calibration positioning rod 401, which is engaged with the transmission gear 301. A through hole is opened in the middle of the rotating disk 3, and the size of the through hole is larger than the diameter of the calibration positioning rod 401. This structure allows the calibration positioning rod 401 to rotate. The through hole in the middle of the disc 3 allows for smooth movement. The calibration positioning rod 401 is inserted into the valve 7, and the valve 7 is placed on the rotating disc 3. This structure allows the valve 7 to rotate synchronously when the rotating disc 3 rotates through the drive gear 501 driving the transmission gear 301. By inserting the calibration positioning rod 401 into the valve 7, the position of the valve 7 can be calibrated, ensuring that the center position of the valve 7 corresponds to the center position of the rotating disc 3. This ensures the effectiveness of the first visual measurement mechanism 10 in visually measuring the side of the valve 7. The output end of the rotary drive mechanism 5 is fixed with a drive gear 501, and the drive gear 501 meshes with the transmission gear 301. The top side of the calibration positioning rod 401... The calibration positioning rod 401 is inclined and has a clearance fit with the transmission gear 301. This structure avoids the calibration positioning rod 401 from hindering the rotation of the transmission gear 301 through the clearance fit between the calibration positioning rod 401 and the transmission gear 301. At the same time, the transmission gear 301 is stable with the rotating disk 3, which can realize the smooth rotation of the rotating disk 3. The friction-reducing balls 402 are evenly spaced and movably embedded on the upper side of the calibration positioning rod 401, and the friction-reducing balls 402 roll in contact with the inner wall of the valve 7. This structure allows the calibration positioning rod 401 to be smoothly inserted into the valve 7 through the friction-reducing balls 402, and the valve 7 can avoid the calibration positioning rod 401 from causing obstruction when it rotates with the rotating disk 3.

[0019] Working principle: When using this rapid calibration valve machining dimension measuring device, the main body 1 of the valve dimension measuring device first places the machined valve 7 inside the housing 6, supported by the rotating disk 3. Then, the servo lifting hydraulic cylinder 4 is activated, causing the calibration positioning rod 401 to rise and engage with the valve 7. At this time, the valve 7 and the rotating disk 3 are aligned, achieving the calibration of the valve 7 position. The drag-reducing ball 402 reduces the drag on the movement of the calibration positioning rod 401. Next, the rotary drive mechanism 5 is activated, driving the transmission gear 3 through the drive gear 501. 01. The transmission mechanism enables the rotation of the rotary disk 3, allowing the first vision measurement mechanism 10 to perform side vision measurement on the valve 7 to measure the length and angle of each part, ensuring the external dimensions of the valve 7. At the same time, the second vision measurement mechanism 12 performs vision measurement on the valve 7 from the top, measuring the diameter of the head and the diameter of the stem. The supplementary light 11 plays a supplementary lighting role during the measurement process. The support plate 2 cooperates with the upper sealing plate 8 for the rotation positioning of the rotary disk 3. The stabilizing bracket 9 ensures that the servo lifting hydraulic cylinder 4 and the rotary drive mechanism 5 have a reliable positioning structure, thereby completing a series of tasks.

[0020] 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.
