Description

TECHNICAL FIELD

[0001] The present application relates to the engine detection technical field, especially relates to a dynamic detection device for protruding height of fuel injector. BACKGROUND

[0002] In the assembly process of the workshop, the protruding height detection of the fuel injector is a key quality control link, which is closely related to the performance, reliability and safety of the engine.

[0003] The protruding height of the fuel injector directly affects the relative position with the combustion chamber. If the height is improper, the angle, range and atomization effect of fuel injection will deviate from the design requirements, resulting in insufficient combustion, increased fuel consumption or excessive emissions.

[0004] If the protruding height of the fuel injector is too high, it may collide with the moving parts such as the piston and the valve, causing engine noise, wear and even serious failure (such as piston top penetration); if the height is too low, it may affect the mixing effect of fuel spray and intake air;

[0005] When the fuel injector is installed, it needs to be tightly attached to the sealing surface of the cylinder head or the combustion chamber. If the protruding height is abnormal, it may cause poor sealing, leading to fuel leakage, air tightness failure, and even engine starting difficulty or running out;

[0006] In batch production, uniform protruding height of the fuel injector is the basis to ensure the consistency of engine performance. Detection can reduce individual differences caused by assembly errors and ensure the stability of key parameters such as power output and emission indicators of the same type of engine.

[0007] The existing protruding height detection scheme of the fuel injector has certain drawbacks. The operation process of the existing protruding height detection scheme of the fuel injector is relatively complicated. The post operator needs to first stand up the cylinder head, assemble the fuel injector to the position with copper pad, and then hold the detection dial gauge to check the protruding height of the fuel injector.

[0008] In this process, the post operator needs to manually measure, and the number of fuel injectors is large, which needs to be measured multiple times. The manual measurement method has certain measurement error, it is difficult to ensure product consistency, and the measurement time is relatively long, the overall measurement efficiency is relatively low, and after measurement, manual data uploading is required, which cannot be used for post-quality analysis and traceability management;

[0009] In summary, the existing scheme has certain defects when in use, and does not meet the requirements of mechanical automation processing. Therefore, we propose a dynamic detection device for protruding height of fuel injector. SUMMARY

DETAILED DESCRIPTION

[0057] In order to make the technical means, creative features, purposes and effects achieved by the application easy to understand, the application will be further described below in combination with specific embodiments.

[0058] The application provides a dynamic detection device for the protruding height of an oil injector, which solves the problems in the prior art that the existing oil injector protruding height detection scheme has certain drawbacks, the operation process of the existing oil injector protruding height detection scheme is relatively complicated, and post operators need to first stand up the cylinder cover, assemble the oil injector to the position by adding a copper pad, then hold a detection dial indicator to check the protruding height of the oil injector. In this process, the post operators need to manually measure, and the number of oil injectors is large, so the measurement needs to be performed multiple times. The manual measurement has certain errors, it is difficult to ensure product consistency, the measurement time is relatively long, the overall measurement efficiency is relatively low, and the data needs to be manually uploaded after measurement, so that the quality analysis and traceability management in the later stage cannot be performed.

[0059] Embodiment 1

[0060] As Figures 1-7As shown, a dynamic detection device for fuel injector protrusion height is used for automatically detecting the fuel injector protrusion height of the cylinder head of a plurality of fuel injectors on a cylinder seat body 2, which is arranged on a material turnover device 1 and comprises a support frame 3, a transverse moving assembly 4 and a detection assembly 5.

[0061] The support frame 3 is fixedly installed on the side end face of the material turnover device 1, and when being installed, the support frame 3 needs to be perpendicular to the table face of the material turnover device 1 to avoid the deviation of the transverse moving track of the detection assembly 5 from the arrangement direction of the fuel injectors on the cylinder seat body 2 due to the inclination; the transverse moving assembly 4 is installed on the support frame 3; and the detection assembly 5 is installed on the transverse moving assembly 4 and is used for detecting the fuel injector protrusion height of the cylinder head.

[0062] During detection, the transverse moving assembly 4 drives the detection assembly 5 to move transversely above the plurality of fuel injectors to detect the fuel injector protrusion height of the cylinder head in sequence.

[0063] Before detection, the model parameters of each cylinder seat body 2 to be detected need to be input, including the number of fuel injectors and the transverse spacing between adjacent fuel injectors, so that the data can be directly applied for subsequent detection.

[0064] This part of structure is mainly designed for the existing scheme using the manual measurement method of workers, and the automatic measurement method of the equipment is developed to realize the automatic measurement of the fuel injector protrusion height of the cylinder head.

[0065] In use, after the cylinder seat body 2 is fixed, the transverse moving assembly 4 is started, the transverse moving assembly 4 drives the detection assembly 5 to move, so that the detection assembly 5 is located above different fuel injectors in sequence, and at this time, the detection assembly 5 detects different fuel injectors in sequence, thereby realizing the measurement of the fuel injector protrusion height of the cylinder head of the plurality of fuel injectors on the cylinder seat body 2.

[0066] The device is the measurement part of the dynamic detection system for fuel injector protrusion height, the collected data is directly fed back to the dynamic detection system for fuel injector protrusion height, the time is automatically stored and marked, the subsequent feedback is facilitated, and when the collected data does not meet the standard, i.e. abnormal data, the device automatically feeds back, and the use effect is good.

[0067] The measured data is uploaded to the dynamic detection system for fuel injector protrusion height, which can be viewed and compared in the later period, quickly found, and help relevant technical personnel to analyze, the use effect is good, and the quality of the product can be better controlled.

[0068] The device is integrated in the material turnover device 1, and the detection can be completed during the turnover of the cylinder seat body 2, without additional loading and unloading and station switching time. The switching time of the detection assembly 5 driven by the transverse moving assembly 4 between multiple oil injectors is less than or equal to 0.5 seconds per oil injector. Compared with the traditional manual detection (single group time is greater than or equal to 60 seconds), the efficiency is improved by more than 6 times, which effectively adapts to the beat demand of the production line.

[0069] The detection process does not require manual intervention: from the automatic positioning of the transverse moving assembly, the position calibration of the inclination correction member, to the data acquisition and analysis of the vertical detection member, the whole process is automatically completed by the system. At the same time, the data can be uploaded to the production management system in real time, which saves the manual recording and uploading steps and further shortens the detection link.

[0070] The detection data of each oil injector can be automatically recorded, and the key words such as production batch, detection time and product model can be quickly queried to realize the whole life cycle quality traceability from the parts to the finished products.

[0071] The present scheme can effectively solve the problem of traditional manual detection in the prior art, which requires an operator to carry the cylinder cover, manually calibrate the dial gauge and repeatedly bend down to measure, and has high labor intensity and requires professional skill training. The device realizes automatic detection, and the operator only needs to complete the loading and starting operation of the cylinder seat body, and the labor intensity is reduced by 70%. At the same time, the system is equipped with a visual operation interface (including fault prompt and processing guide), and the training period of new employees is shortened to one day, reducing the dependence of the production line on skilled workers.

[0072] The present scheme provides a dynamic detection device for the protruding height of an oil injector, which is provided with a transverse moving assembly 4 and a detection assembly 5 on a material turnover device. During the detection process, the transverse moving assembly 4 can drive the detection assembly 5 to move left and right, so that the detection assembly 5 is located directly above different oil injectors, so that the detection assembly 5 can detect oil injectors at different positions, the detection is more comprehensive, the use effect is good, and the device has good use prospect.

[0073] Embodiment 2

[0074] Based on the embodiment 1, as shown in Figures 1-7 The present embodiment also describes the following structure:

[0075] The transverse moving assembly 4 includes a mounting frame 41, a first lead screw transmission assembly 42 and a moving seat 43:

[0076] The mounting frame 41 is fixedly installed on the end face of the support frame 3 facing the cylinder seat body 2; the first lead screw transmission assembly 42 is arranged on the mounting frame 41; and the moving seat 43 is installed on the lead sleeve of the first lead screw transmission assembly 42.

[0077] The guide rail 44 is fixedly installed on the mounting frame 41, and the first screw driving assembly 42 drives the moving seat 43 to slide along the guide rail 44.

[0078] The above structure is mainly designed for the accurate detection of a plurality of groups of fuel injectors, and thus the position of the detection assembly 5 needs to be accurately changed, and thus a structure with high accuracy is adopted, and thus a screw structure is preferred to ensure that the moving seat 43 can be accurately positioned and is convenient to use.

[0079] In use, the first screw driving assembly 42 is started to drive the moving seat 43 to move transversely, so as to change the position of the moving seat 43, so that the moving seat 43 moves to the top of the fuel injectors at different positions, thereby changing the position of the detection assembly 5, so that the fuel injectors at different positions can be conveniently detected, and the use effect is good.

[0080] The detection assembly 5 comprises a detection seat 51, an inclination correction member 52 and a vertical detection member 53.

[0081] One end of the detection seat 51 is fixedly installed on the moving seat 43; the inclination correction member 52 is arranged at the lower end of the detection seat 51.

[0082] The vertical detection member 53 is installed at the lower end of the detection seat 51, and the vertical detection member 53 is located at one side of the inclination correction member 52.

[0083] During detection, the inclination correction member 52 corrects the position of the fuel injector, and after correction, the vertical detection member 53 detects the protruding height of the fuel injector.

[0084] The above structure is mainly to realize accurate detection, and the inclination correction member 52 mainly corrects the position of the fuel injector, so as to conveniently adjust the position of the vertical detection member 53, thereby facilitating the detection of the vertical detection member 53, improving the detection accuracy, and having a good use effect.

[0085] In use, the inclination correction member 52 detects the position of the fuel injector, and adjusts the position of the inclination correction member 52 according to the position of the fuel injector, so as to facilitate the further detection of the fuel injector by the inclination correction member 52, and the use effect is good.

[0086] The lower end of the detection seat 51 is provided with an angle adjusting seat 6, and the inclination correction member 52 is fixedly installed on the angle adjusting seat 6.

[0087] The above structure is mainly to realize accurate detection, so that the inclination correction member 52 can accurately correct the position of the fuel injector, so that the position adjustment of the vertical detection member 53 is more convenient and has higher accuracy, and the use effect is good.

[0088] The angle adjusting seat 6 changes the inclination angle of the inclination correction member 52, so that the monitoring range of the inclination correction member 52 is more extensive, and the use effect is good.

[0089] The angle adjusting base 6 comprises a supporting base 61 and a rotating plate 62:

[0090] The supporting base 61 is fixedly installed at the lower end surface of the detection base 51;

[0092] In use, the inclination angle of the rotating plate 62 can be changed through the angle adjusting member, and when the inclination angle of the rotating plate 62 changes, the inclination angle of the inclination correction member 52 also changes, so that the center position of the detection changes, and the use is more convenient.

[0094] The arc-shaped block 63 is fixedly installed on the rotating plate 62; the transmission member 64 is engaged with the strip-shaped teeth on the arc-shaped block 63; and the driving member is installed on the supporting base 61 and used to drive the transmission member 64 to rotate, change the position of the arc-shaped block 63, and further change the inclination angle of the rotating plate 62.

[0095] The arc-shaped block 63 is provided with a plurality of groups of strip-shaped teeth, which are circumferentially distributed and can correspond to the strip-shaped teeth on the transmission member 64 and be engaged with each other, so as to realize stable transmission.

[0096] The above structure is mainly arranged to realize flexible adjustment and accurately collect data.

[0097] The driving member can adopt a servo motor, cooperate with an adjusting hand wheel as shown in the figure, and mainly adjust through the adjusting hand wheel. Small deformation caused by position change of the cylinder seat body 2 or production error can be adjusted through the servo motor. The servo motor is provided with a brake structure, which can lock the position of the transmission member 64, so as to realize adjustment of the angle of the rotating plate 62.

[0098] In use, a servo motor can also be directly used, and the whole process is controlled by the servo motor.

[0099] The inside of the detection base 51 is provided with a position adjusting assembly, and the vertical detection member 53 is installed on the position adjusting assembly.

[0100] The above structure is mainly arranged to improve the existing scheme by adopting manual detection. Generally, the improvement is to improve the intelligent detection of the protruding height of the oil sprayer on the cylinder seat body 2 of a single model, so that the limitation is relatively large. The present scheme is improved in pertinence, and a device capable of detecting multiple models is developed at one time.

[0101] Without designing detection equipment for different models separately, equipment multiplexing rate is improved by 80%, and production line equipment investment cost is reduced.

[0102] When detecting the protruding height of the oil injector on different cylinder seat bodies 2, according to the length of the new model cylinder seat body 2, the upper limit and lower limit of the moving stroke of the first screw rod transmission assembly 42 are modified by the control system, and the moving range of the moving seat 43 is ensured to cover the top of all oil injectors.

[0107] The sliding seat 66 is arranged in the interior of the detection seat 51, and the sliding seat 66 is fixedly connected with the sleeve of the second screw rod assembly 65;

[0108] The lower end surface of the sliding seat 66 is fixedly connected with the vertical detection piece 53 through a connecting block.

[0109] The above structure is mainly arranged to realize the accurate adjustment of the position of the vertical detection piece 53, therefore, the structure of this part also adopts a screw rod structure, and therefore, the second screw rod assembly 65 is adopted to drive the operation of the sliding seat 66.

[0110] In use, the second screw rod assembly 65 can drive the sliding seat 66 to move, so as to change the position of the sliding seat 66, thereby realizing the adjustment of the position of the vertical detection piece 53.

[0111] Two guide rods 67 are arranged in the interior of the detection seat 51, and guide rings 68 are fixedly installed on the two sides of the sliding seat 66, and the guide rings 68 are slidably connected with the guide rods 67.

[0112] The guide rings 68 are slidably connected with the guide rods 67, which can limit the movement direction of the sliding seat 66, so that the sliding seat 66 is stable as a whole and cannot deviate, and has high precision.

[0113] The structure is mainly arranged to realize stable movement of the sliding seat 66, and has good use effect.

[0114] The guide rod 67 cooperates with the guide ring 68, mainly to enable the sliding seat 66 to stably run along the guide rod 67, and ensure the stability of the running, and has good use effect.

[0115] The vertical detection piece 53 and the tilt correction piece 52 each include a telescopic rod with a lifting detection function, in the vertical detection piece 53, a telescopic end of the telescopic rod is fixedly installed with a laser ranging sensor 54, in the tilt correction piece 52, a telescopic end of the telescopic rod is fixedly installed with a lamp ring and a camera assembly, the lamp ring is a LED lamp ring, and the camera assembly is an industrial camera, which cooperate with each other to make the collected pictures clearer, effectively reduce the influence of external light on detection, and have more wide applicability.

[0116] The laser ranging sensor 54 needs to be calibrated regularly, when calibration, a standard gauge block is placed on a detection station, the telescopic rod is elongated to contact the surface of the gauge block, and a difference value between a laser ranging value and a telescopic amount of the telescopic rod is recorded as a subsequent detection reference compensation value.

[0117] The tilt correction piece 52 adopts a close-range shooting mode, can accurately identify whether the oil sprayer is located on the telescopic path of the telescopic rod, and in combination with the telescopic distance, can directly calculate the position of the oil sprayer, for example, the overall distance of the tilt correction piece 52 after telescoping is L, the included angle between the tilt correction piece 52 and the horizontal plane is A, then the total distance is L*cos A, and the distance of the vertical detection piece 53 that needs to be adjusted is L*cos A-d0, and d0 is an initial distance set between the tilt correction piece 52 and the vertical detection piece 53.

[0118] The tilt correction piece 52 cooperates with the vertical detection piece 53 to detect, and the detection precision can reach ±0.01mm, which is much higher than the error range ±0.05mm of the artificial use of a dial gauge, and effectively eliminates the influence of factors such as operation personnel's skill, visual judgment and fatigue on traditional manual detection.

[0119] The double-monitoring mode is adopted in the vertical detection piece 53, has higher precision, and can realize comparison detection to judge whether the detection instrument is damaged, for example, the length of the telescopic rod is compared with the distance detected by the laser ranging sensor 54, and comparison of the two groups of data can realize data detection, and has good use effect.

[0120] The scheme provides a dynamic detection device for the protruding height of an oil sprayer, which realizes multi-dimensional performance improvement in the engine oil sprayer detection link through the combination of structural design and automation technology, and effectively solves the drawbacks of traditional manual detection, and is more suitable for the core needs of modern industrial automation production.

[0121] The telescopic end of the vertical detection piece 53 can be provided with a pressure sensor to determine whether the telescopic end of the telescopic rod contacts the oil sprayer, and the use effect is good, and has good use prospect.

[0122] After detection is completed, the system automatically stores the following data:

[0123] Basic information: detection time needs to be accurate to milliseconds, cylinder seat body number associated with production batch, and detection personnel ID;

[0124] Detection data: protruding height measured value of each oil sprayer, difference between laser and telescopic rod, and environmental temperature (built-in temperature sensor, accuracy ±0.5℃) during detection;

[0125] Abnormal record: specific parameters of unqualified items and equipment state when the abnormality occurs.

[0126] Data support can export Excel format or access MES system, historical records can be queried by number, quality trend chart can be generated, and assembly process problems can be traced back.

[0127] It should be noted that the application discloses a dynamic detection device for the protruding height of an oil sprayer, when the cylinder seat body 2 is fixed, the lamp ring and the camera assembly on the telescopic rod in the inclination correction piece 52 are started to take pictures to determine whether the oil sprayer is in the center of the picture, if the oil sprayer is in the center of the picture, no treatment is performed, if the oil sprayer is not in the center of the picture, the driving piece is started to drive the transmission piece 64 to rotate to change the position of the arc-shaped block 63 and the inclination angle of the rotating plate 62, at this time, the telescopic rod in the inclination correction piece 52 is elongated, and the lamp ring and the camera assembly on the telescopic rod in the inclination correction piece 52 are started to take pictures to determine whether the oil sprayer is in the center of the picture, if the oil sprayer is in the center of the picture, no treatment is performed, if the oil sprayer is not in the center of the picture, the adjustment is performed in the above manner until the oil sprayer is in the center of the picture, at this time, the position of the vertical detection piece 53 is calculated, the second lead screw assembly 65 is started to drive the sliding seat 66 to move, so that the position of the sliding seat 66 is changed, so that the position of the vertical detection piece 53 is adjusted, at this time, the basic setting of the position is realized.

[0128] Then the laser ranging sensor 54 in the vertical detection piece 53 is started to detect the distance, and then the telescopic rod in the vertical detection piece 53 is started to detect the telescopic distance, the two groups of data are compared, if the difference is out of the preset range, it is indicated that the instrument is damaged, and an alarm is given, and relevant personnel perform maintenance and repair.

[0129] If the difference is in the preset range, it indicates that the detection data is valid, at this time, it is judged whether the average values of the two groups of detection data are in the interval of the standard injector protrusion height, if yes, the data is saved, if not, an alarm is given and the data is marked.
