Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology and discloses a cylinder block bore surface position detection device and detection system. Background Technology

[0002] As the core load-bearing component of an internal combustion engine, the engine block has a complex structure and integrates multiple key surface features, including cylinder bores, oil holes, bolt holes, locating holes, and various assembly reference surfaces. The positional accuracy of these surfaces directly determines the assembly precision of engine components such as pistons, crankshafts, and cylinder heads, thus affecting the engine's power performance, sealing performance, operational stability, and service life. Industry data shows that 32.7% of commercial engine failures in China originate from cylinder block defects, with out-of-tolerance dimensional deviations in surface positions being a significant component. Therefore, accurate detection of surface positional accuracy is a crucial quality control step in the engine block manufacturing process and one of the core procedures for ensuring engine product qualification.

[0003] Currently, in the field of engine block manufacturing, bore surface position tolerance inspection mainly relies on coordinate measuring machines (CMMs). As a high-precision measuring device, CMMs have become the mainstream choice for form and position tolerance inspection of precision parts due to their micron-level measurement accuracy and ability to measure complex geometries. However, in actual large-scale production scenarios, using CMMs for engine block bore surface position tolerance inspection has many insurmountable drawbacks, severely restricting production efficiency and the timeliness of quality control. Specific problems are as follows:

[0004] First, the inspection efficiency is extremely low, making it difficult to adapt to the needs of large-scale production. Engine cylinder blocks have numerous and densely distributed bore features, some of which are complex structures such as oblique holes. Measurements must be taken strictly along the normal direction of the bore axis to avoid cosine errors. This means the coordinate measuring machine (CMM) must individually sample, locate, and calculate the position of each bore feature. In other words, completing the positional inspection of a single bore requires a complete process of "drilling-surface drilling-data calculation," and inspecting the position of all bores in a single cylinder block often consumes a significant amount of time. Furthermore, the contact-based measurement method of the CMM is inherently slow. Faced with the time constraints of mass production lines, only sampling inspection can be used. Increasing the sample size further increases inspection costs and time, making full inspection coverage difficult and potentially leading to defective products flowing into subsequent processes.

[0005] Secondly, the testing process is cumbersome, resulting in high labor and time costs. Due to its inherent structure and precision requirements, the coordinate measuring machine (CMM) must be installed in a dedicated metrology chamber. This chamber must meet stringent environmental requirements, including constant temperature and vibration damping, and is located a considerable distance from the machine tool used to process the engine block. During testing, dedicated personnel must transport the completed cylinder block from the machining station to the metrology chamber, and then back to the machining area after testing. This entire transport process is not only labor-intensive but also adds to the testing cycle. Furthermore, CMM operation relies on specialized personnel who require professional training to perform programming, data acquisition, and data interpretation, further increasing labor costs. Moreover, operational errors can lead to inaccurate test data and potential quality issues.

[0006] Furthermore, existing alternative testing technologies have significant limitations and cannot meet actual testing needs. While alternative solutions exist in the industry, such as pneumatic gauges, mechanical position gauges, and electronic plug gauges, they all have prominent drawbacks: pneumatic gauges are only suitable for through-hole testing and cannot measure complex hole surfaces and chamfers, and the measurement results are easily affected by air pressure stability; mechanical position gauges are simple in structure and low in cost, but can only be used for testing specific cylinder sizes, cannot achieve simultaneous measurement of multiple parameters, and can only determine pass / fail status, not provide specific adjustment parameters; electronic plug gauges are limited to hole diameter testing, requiring different probes for different sizes, resulting in poor versatility. While laser scanning measurement technology is suitable for measuring free-form surfaces, it suffers from optical obstruction problems when testing deep holes and oblique hole structures, has high equipment investment costs, and requires strict surface roughness, making it difficult to apply to large-scale production scenarios.

[0007] Furthermore, excessively long inspection cycles can disrupt the production process and affect production continuity. Because coordinate measuring machine (CMM) inspection is time-consuming and cumbersome, finished cylinder blocks require a long wait for inspection results. If the inspection reveals out-of-tolerance hole surface position, the cylinder block must be transferred back to the machining station for rework and adjustment. After adjustment, it must be transferred back to the metrology room for re-inspection. Repeated transfers and inspections further extend the production cycle, reduce production efficiency, and may even lead to idle machine tools and wasted capacity. Simultaneously, the lag in inspection results prevents timely feedback to the machining process, hindering real-time optimization and potentially leading to batch-wide out-of-tolerance hole surface position, increasing production costs and scrap rates.

[0008] In summary, the current reliance on coordinate measuring machines (CMMs) for engine block bore position measurement suffers from significant drawbacks, including low efficiency, cumbersome processes, high labor costs, and long inspection cycles. Existing alternative technologies cannot simultaneously meet the demands for high precision, high efficiency, and versatility, making them unsuitable for the large-scale, high-precision production requirements of engine blocks. Therefore, developing a solution that addresses these technical challenges and enables rapid, accurate, and efficient detection of engine block bore position has become a pressing technical issue in engine manufacturing. This solution holds significant engineering value and practical importance for improving engine production efficiency, ensuring product quality, and reducing production costs. Summary of the Invention

[0009] The purpose of this invention is to provide a cylinder bore surface position detection device and system. It has a simple structure and low cost. It adopts the form of line-side inspection tool. The cylinder to be tested can be directly put into the device for testing after processing. It is only necessary to simply plug and unplug the cylinder to determine whether the cylinder is qualified. It is quick and convenient, shortens the testing time, greatly improves the testing efficiency, and eliminates the need to remove the cylinder to be tested from the production line for testing, reducing labor intensity and avoiding bumps and damage caused during transportation.

[0010] The specific details of the plan are as follows:

[0011] A cylinder block bore position measurement device includes a measurement platform and a bore position gauge. The measurement platform includes a bottom frame, a measurement plate, a lifting device, and a conveying device. The bottom frame includes a top plate with a through hole fixed to the top of the bottom frame. The lifting device includes a drive unit and a lifting bracket. The drive unit is fixed to the lower end face of the top plate, and the drive unit and the lifting bracket are drivenly connected. The lifting bracket is exposed above the through hole in the top plate, and its top is fixedly connected to the lower end face of the measurement plate. The conveying device includes a guide rail and a loading tray. The guide rail is... The two-section linear guide rail is fixed to the test platform and the adjacent top plate, respectively, and extends beyond the top plate. The loading tray is slidably connected to the guide rail and is used to transport the cylinder body to be tested. The hole position gauge includes multiple templates and multiple test pins. Each template is equipped with multiple pin guide sleeves. The pin guide sleeves match the holes on the corresponding test surfaces of the standard cylinder body. The test pins can be simultaneously inserted into the corresponding pin guide sleeves and the corresponding holes on the standard cylinder body. The templates are set on the top plate and are matched and adjacent to the test surfaces of the cylinder body to be tested.

[0012] The hole position gauge of the cylinder bore surface position detection device of the present invention includes templates and detection pins. Multiple templates are provided, the number being the same as the number of bore surfaces to be detected on the cylinder. Each template is manufactured according to the standard detection surface of the cylinder to be detected. Each template is equipped with multiple pin guide sleeves. The number, shape, size, and distribution of the pin guide sleeves match the hole arrangement on the bore surface to be detected on the cylinder. The number, size, and shape of the detection pins match the corresponding pin guide sleeves and the corresponding holes on the cylinder, ensuring that when the template is fixed on the detection table and adjacent to the standard cylinder detection surface, the detection pins can be simultaneously inserted into the pin guide sleeves and the corresponding holes, thus determining that the cylinder is qualified. When detecting the cylinder, simply insert the corresponding detection pin into the corresponding pin guide sleeve and the hole of the cylinder. If insertion is not possible, the cylinder is deemed unqualified; if insertion is successful, the workpiece is deemed qualified. The number of templates used is selected based on the inspection surface of the workpiece. This invention designs five templates; the fifth template is only used when inspecting a specific cylinder body. Generally, only the first, second, third, and fourth templates are needed. The inspection table frame is a cuboid frame structure, with a rectangular plate on the top of the bottom frame, fixed to the top of the bottom frame. A through hole is provided on the top plate, and the drive device of the lifting device is installed on the lower end face of the top plate. The drive device and the lifting frame are connected, and the lifting frame extends through the through hole and is fixedly connected to the lower end face of the inspection table. The inspection table can rise and fall with the lifting device. The guide rail of the conveying device is a two-section linear guide rail structure, meaning one linear guide rail consists of two sections. The front section is installed on the inspection table, and the rear section is installed on the adjacent top plate via a support frame, extending beyond the front end of the top plate. The support frame has a certain height, allowing the tops of the front and rear sections of the lifting device to be flush. In a preferred embodiment of the invention, two parallel, two-section guide rails are arranged at intervals on the testing platform. A lifting device keeps the front and rear guide rails flush, forming a continuous linear guide rail. A loading tray is slidably limited and connected to the guide rails; the loading tray is in the loading position when it is on the rear guide rail. The worker places the cylinder to be tested on the loading tray and pushes it onto the front guide rail of the testing platform for positioning, i.e., the testing position. Multiple positioning pins are provided on the top plate, and matching positioning pin holes are provided on both the testing platform and the loading tray. The positioning pins pass through the positioning pin holes when the testing platform descends with the loading tray, and then through the blank reference hole on the bottom surface of the cylinder to be tested to position the cylinder. The testing platform is equipped with corresponding templates around its perimeter. After the loading tray is pushed into the testing position, the testing platform is lowered by the lifting device until the positioning pin is inserted into the positioning pin hole and the reference hole on the bottom blank of the cylinder body to be tested. Then the testing begins. The testing pin is inserted into the corresponding pin guide sleeve and the corresponding hole on the cylinder body to be tested. If it is inserted smoothly, the cylinder body to be tested is qualified. If it cannot be inserted smoothly, it is unqualified.The detection device of the present invention has a simple structure and is convenient for detection. Compared with the traditional coordinate measuring machine, the detection cost is low. It can be in the form of an in-line inspection fixture. After the cylinder workpiece is processed, it can directly enter the detection device for detection, and there is no need to move the workpiece from the production line for inspection. This reduces the labor intensity of workers and avoids the collision damage caused during the handling process.

[0013] The present invention also provides a cylinder block hole surface position degree detection system, which further includes a control unit and a display device. The control unit is used to control the display device to display the hole positions to be detected on the cylinder block to be detected and the detection pins to be used. The display device is arranged on the ground on one side of the cylinder block hole surface position degree detection device. The cylinder block hole surface position degree detection device is the detection device in the system. A plurality of pin indicator lights are provided on each storage board, and each pin indicator light is arranged in front of the corresponding pin storage hole. The pin indicator light is matched with the corresponding detection pin, and the pin indicator light is electrically connected to the control unit. A preset program is pre-entered in the control unit. When detecting, according to the preset program, it instructs the worker to perform the detection. The detection pins to be detected and the template positions where the detection pins are located are displayed on the display device. The pin indicator light in front of the detection pin on the storage board lights up. The worker inserts the detection pin into the corresponding guide sleeve according to the instructions and then inserts it into the corresponding hole position on the adjacent cylinder block to be detected. If it can be inserted smoothly, it is qualified; if not, it is unqualified. In the additional detection system of the present invention, by controlling the display device and the pin indicator lights to light up through the control unit, it is convenient for the operation of personnel, avoids inserting the wrong detection pins, saves the detection time, and improves the accuracy of detection at the same time.

[0014] Furthermore, the bottom bench has a cuboid structure. The top plate of the bottom bench is a rectangular plate and has a plurality of positioning pins. Matching positioning pin holes are provided on both the detection table plate and the loading tray. The positioning pins can sequentially pass through the positioning pin holes of the detection table plate and the loading tray and protrude above the loading tray, for positioning with the bottom blank reference holes of the cylinder block to be detected. The driving device of the lifting device includes a first cylinder, which is fixedly connected to the lower end surface of the top plate, and its telescopic end extends upward from the through hole to be drivingly connected to the lifting bracket. The top of the lifting bracket is fixedly connected to the lower end surface of the detection table plate.

[0015] The driving device of the lifting device of this invention can be a cylinder or a motor, etc., which can be selected according to actual needs. Since it is prior art, it will not be elaborated here. This invention uses a cylinder, which is named the first cylinder here to distinguish it from the cylinder in the fifth template lifting device. The telescopic end of the first cylinder extends upward through the through hole and is driven to connect with the lifting bracket. The top of the lifting bracket is fixedly connected to the lower end surface of the detection platform. Before loading, the telescopic end of the first cylinder remains in the extended state, that is, the detection platform is in the raised state, ensuring that the top of the front guide rail fixed on the detection platform and the rear guide rail on the top plate are flush to form a continuous linear guide rail, so that the loading tray can slide on the guide rail. After the loading tray carrying the cylinder to be tested is pushed into the detection position, the first cylinder of the lifting device drives the detection platform to descend until the cylinder to be tested is positioned by the positioning pin and then stops. The control of the lifting device is accomplished by the lifting controller.

[0016] Furthermore, there are two guide rails, which are parallel and spaced apart on the detection platform and the top plate. Each guide rail includes a front guide rail and a rear guide rail. The two front guide rails are fixedly connected to the detection platform in parallel and spaced apart. The conveying device also includes two support frames. The same side ends of the two support frames are respectively fixedly connected to the top plate adjacent to the corresponding front guide rail, and the other end extends beyond the top plate. The two rear guide rails are respectively fixedly connected to the corresponding support frames. The front and rear guide rails on the same side are closely adjacent to each other to form a continuous straight guide rail. The loading tray can be limited and slidably connected to the two guide rails, and the loading tray can be limited and connected to the front guide rail or the rear guide rail.

[0017] Furthermore, the template includes a first template, a second template, a third template, and a fourth template. The first and second templates are vertically fixed to the top plates on the left and right sides of the test platform, respectively. The third template is vertically fixed to the top plate on the rear side of the test platform. The fourth template is horizontally fixed to the top of the first and second templates. The first, second, third, and fourth templates are each provided with multiple pin guide sleeves. The number, position, and size of the pin guide sleeves on each template are matched with the hole positions on the test surface of the cylinder body adjacent to the template. This is used to detect the hole position of the test surface of the cylinder body through the matching test pins.

[0018] The commonly used templates in this invention are four templates: the first template, the second template, the third template, and the fourth template. These are set according to the actual situation of the cylinders being tested in this company. The most fundamental working principle is based on the number of test surfaces of the cylinder being tested. Each template corresponds to a test surface. Each template is equipped with a pin guide sleeve. The test pin and the pin guide sleeve match the corresponding test hole on the standard cylinder body. When the cylinder being tested is qualified, the test pin can be inserted into the corresponding pin guide sleeve and enter the corresponding hole on the adjacent cylinder being tested at the test position. Otherwise, it cannot be inserted.

[0019] Furthermore, the template also includes a fifth template, which is equipped with multiple pin guide sleeves. The testing platform also includes a door frame mounting frame and a fifth template lifting device. The door frame mounting frame includes two columns and a crossbeam. The crossbeam is horizontally fixedly connected to the top of the two columns. The bottom of the two columns is fixedly connected to the left and right sides of the front end face of the top plate, respectively. The front ends of the first and second templates are fixedly connected to the rear ends of the two columns, respectively. The front end of the fourth template is fixedly connected to the crossbeam. The fifth template lifting device includes a drive device, two slide rails, two sliders, and a lifting frame. The drive device includes a second cylinder. The two slide rails are vertically fixedly connected to the two columns, and the two sliders are limited and slidably connected to the two slide rails, respectively. The two ends of the lifting frame are fixedly connected to the two sliders, respectively. The fifth template is fixedly connected to the lifting frame. The top plate below the left column / right column is provided with a through hole. The second cylinder is fixedly connected to the lower end face of the top plate. The telescopic end of the second cylinder passes through the through hole and is drivenly connected to the adjacent slider.

[0020] The cylinder under test in this invention also includes a cylinder detection surface corresponding to the fifth template that needs to be tested. Since the fifth template is located at the front end of the testing platform, considering the material feeding issue of the loading tray, a portal frame mounting bracket and a fifth template lifting device are provided on the front end face of the top panel. The fifth template lifting device is mounted on the portal frame mounting bracket, and the fifth template is fixed to the lifting bracket. It is connected to the lifting bracket via a slide rail slider, the lifting bracket, and a second cylinder. The second cylinder moves the lifting bracket up and down on the slide rail, allowing the fifth template to move up and down without affecting the material feeding of the loading tray. The design principle of the fifth template is the same as that of other templates, and will not be repeated here.

[0021] Furthermore, the testing platform also includes a lifting controller, which is fixedly connected to the support frame and electrically connected to the first cylinder and the second cylinder respectively.

[0022] The testing platform also includes a lifting controller, which is electrically connected to the first cylinder and the second cylinder respectively. One or two lifting controllers can be installed, fixedly connected to the corresponding support frames, and used to control the lifting movement of the lifting device and the fifth template lifting device.

[0023] Furthermore, the testing station also includes a pin storage base, which includes multiple storage plates. The multiple storage plates are fixedly connected to the top outer surface of the bottom frame. Each storage plate has multiple pin storage holes. The number of pin storage holes matches the number of testing pins. The testing pins can be inserted into the corresponding pin storage holes.

[0024] Furthermore, the detection pins include positional pins and touch gauge pins.

[0025] The core components of the detection device of the present invention include various templates corresponding to the detection surface of the cylinder block being tested, position pins corresponding to the holes, and touch gauge pins corresponding to the surfaces.

[0026] A cylinder bore position measurement system includes the aforementioned cylinder bore position measurement device, and also includes a control unit and a display device. The control unit is used to control the display device to display the bore position to be measured on the cylinder and the detection pin to be used. The display device is set on the ground to one side of the cylinder bore position measurement device.

[0027] Furthermore, each storage plate also includes multiple pin indicator lights, each pin indicator light is located in front of the corresponding pin storage hole, the pin indicator light matches the corresponding detection pin, and the pin indicator light is electrically connected to the control unit.

[0028] The monitoring system of the present invention controls the display device and the indicator light of the plug to light up through the control unit, which facilitates the operation of personnel, avoids inserting the wrong detection plug, saves detection time, and improves the accuracy of detection.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1. The detection device of the present invention has a simple structure and low cost. It can directly determine whether the workpiece is qualified by simply plugging and unplugging, which is quick and convenient, shortens the detection time, and greatly improves the detection efficiency.
