Description

Technical Field

[0001] This invention relates to the field of internal combustion engine bearing assembly technology, specifically a visual error-proofing device for bearing assembly based on light marking. Background Technology

[0002] Internal combustion engine bearing shells are the parts that contact the sliding bearing and the journal. They are semi-cylindrical in shape, with a very smooth, tile-like surface, and are generally made of wear-resistant materials such as bronze or anti-friction alloys. In special cases, they can be made of wood, engineering plastics, or rubber. Bearing shells come in two types: integral and split. Integral bearing shells are usually called bushings. Integral bearing shells are available with or without oil grooves. The bearing shell and journal use a clearance fit and generally do not rotate with the shaft.

[0003] The diameter requirements for crankshaft journals are very strict. Usually, after the crankshaft is machined, the actual size of the journals is measured and they are grouped into red and blue groups. Generally, the journals with a lower tolerance are in the blue group, and the journals with a higher tolerance are in the red group. The journals are marked with red and blue paint pens respectively.

[0004] During the final assembly of an internal combustion engine, the bearing shells must be selected according to the color of the crankshaft journals. Blue journals with a lower diameter require thicker blue bearing shells, while red journals with a higher diameter require thinner red bearing shells. This ensures the clearance between the bearing shells and the crankshaft is within the appropriate range, guaranteeing product quality. Incorrect installation, such as a thin bearing shell on a journal with a lower diameter causing excessive clearance, can lead to engine malfunctions and low oil pressure. Conversely, a thick bearing shell on a journal with a higher diameter causing insufficient clearance can result in increased engine friction, reduced output performance, or even crankshaft seizure.

[0005] The current assembly of bearing bushes mainly involves workers observing the color markings on the crankshaft journals and memorizing the information of a certain color journal. Then, they take the bearing bushes and install them on the corresponding journals. However, in actual operation, due to the possibility of memory fuzziness, memory errors, and forgetting, it is difficult for workers to install bearing bushes with the correct crankshaft grouping information in subsequent operations.

[0006] To reduce the risk of incorrect bearing installation to some extent, with the continuous development of technology, the QR code on the crankshaft is scanned in advance to transmit the grouping information of the crankshaft journals to the computer screen of the bearing assembly station. Employees need to look up at the screen while installing the bearings. However, it is still easy to misread the gear position, and frequently looking up at the screen affects the work efficiency and does not meet the requirements of assembly efficiency and accuracy. Therefore, a visual error prevention device for bearing assembly based on light marking has been developed. Summary of the Invention

[0007] To overcome the shortcomings of the prior art, this application provides a visual error prevention device for bearing assembly based on light marking. It can identify the internal combustion engine cylinder block data before bearing assembly and illuminate the corresponding bearing assembly position with light that identifies the bearing type according to the identification result. This makes it convenient for on-site personnel to use without having to memorize the bearing type and position during the bearing assembly process. It can effectively improve the assembly efficiency and accuracy of bearings, and has good application prospects.

[0045] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0046] Example 1:

[0047] This embodiment describes the specific structure of a visual error-proofing device for bearing assembly based on light-marking, as detailed in the following reference. Figures 1 to 8 As shown, it includes a support base 2 and a suspension assembly 3:

[0048] The upper end of the support base 2 is provided with a limiting component 21 for limiting the position of the internal combustion engine cylinder block 1. When installing the bearing, the internal combustion engine cylinder block 1 is limited by the limiting component 21 to ensure the stability of the limiting component 21 during the installation process. The lower end face of the suspension assembly 3 is provided with a light marking component 31 for identifying the bearing type. The light marking component is located directly above the internal combustion engine cylinder block 1. The light marking component 31 marks the installation position of the bearing on the internal combustion engine cylinder block 1 by emitting rays of different colors, which has a good effect. The side end of the support base 2 is provided with an identification component 22 for identifying the side QR code of the internal combustion engine cylinder block 1. Both the identification component 22 and the light marking component 31 are connected to the internal combustion engine assembly management system. The identification component 22 is used to send the identified internal combustion engine model to the internal combustion engine assembly management system. The light marking component 31 is used to receive the light command issued by the internal combustion engine assembly management system and illuminate the bearing installation position according to the light command.

[0049] During use, the machined internal combustion engine cylinder block 1 is transported and placed on the support base 2. At this time, after the identification component 22 identifies the side QR code of the internal combustion engine cylinder block 1, it sends the identified internal combustion engine model to the internal combustion engine assembly management system. At the same time, it obtains the pre-scanned crankshaft QR code information from the internal combustion engine assembly management system. Based on the internal combustion engine model and the crankshaft QR code information, the internal combustion engine assembly management system calculates the corresponding bearing installation type and sends the corresponding light marking instruction to the light marking component 31. The light marking component 31 receives the light instruction from the internal combustion engine assembly management system and illuminates the bearing installation position according to the light instruction. At this time, the on-site operator directly installs the bearing according to the light instruction to ensure that the bearing type is installed accurately.

[0050] This invention provides a visual error-proofing device for bearing assembly based on light marking. It can identify the data of the internal combustion engine cylinder block 1 before bearing assembly and calculate the bearing installation type by combining the crankshaft QR code information obtained by the internal combustion engine assembly management system. Based on the calculation result, the light marking the bearing type is shone on the corresponding bearing assembly position. This eliminates the need for on-site operators to separately memorize the bearing type and position during the bearing assembly process. It is convenient to use, effectively improves the assembly efficiency and accuracy of bearings, and has good application prospects.

[0051] Example 2:

[0052] Based on Example 1, such as Figures 1-8 As shown, this embodiment also describes the following structure:

[0053] The limiting component 21 includes a support column 212, a limiting ring 211, and a support member 213.

[0054] The number of support columns 212 is several sets, and several sets of support columns 212 are fixedly installed on the upper end face of the support base 2; the limiting ring 211 is fixedly installed on the support column 212 through the support column; the support member 213 is installed in the middle position of the upper end face of the support base 2; the limiting ring 211 limits the position of the outer side of the internal combustion engine cylinder block 1, and provides a corresponding protective foundation when the internal combustion engine cylinder block 1 is transported and suspended, and the use effect is good.

[0055] Among them, the limiting ring 211 is provided with several sets of rotating clips 214, and the rotating clips 214 are in contact with the support member 213.

[0056] The limiting ring 211 has several sets of notches, and the notches are connected by rods. The collar in the middle of the rotating clamp 214 is rotatably mounted on the rod by bearings. A torsion spring can also be installed on the collar to achieve partial limiting of the rotating clamp 214, so as to avoid the position of the rotating clamp 214 from affecting the placement of the internal combustion engine cylinder block 1, thus making it more convenient to use.

[0057] Support member 213 includes a base and a movable seat 2131:

[0058] The base is fixedly installed at the middle position of the upper end face of the support seat 2; the movable seat 2131 is slidably connected to the base, and the internal combustion engine cylinder 1 is placed on the upper end of the movable seat 2131; by adopting the sliding connection between the movable seat 2131 and the base, the height of the movable seat 2131 can be adjusted, so that it can be used for different internal combustion engine cylinders 1 (slender and tall type and flat type). A hydraulic support component is provided in the cavity between the base and the movable seat 2131.

[0059] When the internal combustion engine cylinder block 1 is of the slender and tall type, in order to facilitate the installation of bearing bushes, it is necessary to reduce the height of the internal combustion engine cylinder block 1. At this time, the hydraulic support is activated to reduce the height of the internal combustion engine cylinder block 1, thereby facilitating installation.

[0060] A clamping block 2141 is installed on the upper end of the rotating clamp 214 facing the internal combustion engine cylinder 1. The clamping block 2141 is made of elastic material, so it has a certain amount of room to move, thereby enabling the limiting of different models of internal combustion engine cylinder 1. Several sets of slots 2142 are equally spaced on the lower end of the rotating clamp 214 facing the internal combustion engine cylinder 1. Several sets of support blocks 2132 are provided on both sides of the movable seat 2131. When the internal combustion engine cylinder 1 is located on the movable seat 2131, the support blocks 2132 are engaged with the slots 2142.

[0061] The support block 2132 on the movable seat 2131 engages with the slot 2142 on the rotating clamp 214, thereby limiting the tilt angle of the support block 2132 and limiting the clamping block 2141 on the support block 2132 to the internal combustion engine cylinder 1.

[0062] The rotating clamp 214 is rotatably mounted on the limiting ring 211 at the middle position. A reinforcing rib 2143 is installed on the side of the rotating clamp 214 away from the internal combustion engine cylinder 1, which can increase the strength of the rotating clamp 214 and thus extend the service life of the rotating clamp 214, resulting in good performance.

[0063] A weighing sensor is installed at the lower end of the support 213. The weighing sensor is a Mettler Toledo SLR110-1T. Both the weighing sensor and the identification component 22 are connected to the internal combustion engine assembly management system. The weighing sensor is used to send the weight of the internal combustion engine cylinder block 1 to the internal combustion engine assembly management system. The identification component 22 is used to receive the adjustment signal and scanning signal sent by the internal combustion engine assembly management system and to identify the QR code marked on the side of the internal combustion engine cylinder block 1.

[0064] Different models of internal combustion engine cylinder blocks 1 have different heights. After the weighing sensor weighs the cylinder, it sends the weight data to the internal combustion engine assembly management system. At this time, the internal combustion engine assembly management system uses a threshold comparison method to perform a preliminary identification of the internal combustion engine cylinder block 1, identify the shape of the internal combustion engine cylinder block 1, retrieve the corresponding adjustment data, generate an adjustment signal from the adjustment data, and send it to the identification component 22. The identification component 22 receives the adjustment signal and scanning signal sent by the internal combustion engine assembly management system and identifies the QR code marked on the side of the internal combustion engine cylinder block 1.

[0065] For example: The appropriate height for on-site personnel to install the bearing bush is K, while the initial height of the movable seat 2131 is m, and the height of the internal combustion engine cylinder block 1 is n. At this time, the adjustment signal includes the height m+nK of the hydraulic support component descending.

[0066] The identification component 22 includes a lifting column and an identification plate. The main body of the lifting column is fixedly installed on the upper side of the support base 2. The identification plate is installed on the telescopic end of the lifting column. A scanning device for identifying QR codes and a light ring are embedded in the identification plate. The light ring is located outside the lens of the scanning device. The scanning device is a Chiteng CT1030.

[0067] The purpose of the light ring is to supplement the light, so that the scanning device lens can identify more clearly, resulting in better performance.

[0068] Based on the location of the corresponding inkjet, we know that the QR code is located at position 'a' from the top of the internal combustion engine cylinder block 1, while the initial height of the scanning device lens is 'b'. At this point, the required height of the lifting column is 'Kab', making it more convenient to use.

[0069] This invention provides a visual error-proofing device for bearing assembly based on light marking, which can limit the position of the internal combustion engine cylinder 1 during bearing installation. It can be applied to fixing the position of the internal combustion engine cylinder 1 of different models, and can keep the height of the internal combustion engine cylinder 1 consistent during assembly, thereby facilitating the quick assembly of bearings by on-site personnel. It has good performance and good application prospects.

[0070] Example 3:

[0071] Based on Example 2, such as Figure 1-8 As shown, this embodiment also includes the following:

[0072] The light-marking component 31 includes a linear track 311 and an electric slider 312.

[0073] The linear track 311 is fixedly installed at the middle position of the lower end face of the suspension assembly 3; there are several sets of electric sliders 312, and all sets of electric sliders 312 are slidably installed on the linear track 311.

[0074] The electric slider 312 moves linearly along the linear track 311. The electric slider 312 can move to any position along the linear track 311, which makes it convenient to mark different internal combustion engine cylinder blocks 1. This is mainly because there are certain differences in the placement position of the internal combustion engine cylinder block 1, and the bearing installation position is different for different models of internal combustion engine cylinder block 1. If it cannot be marked at the bearing installation position, the marking is not sufficient and the use effect is not good.

[0075] A camera assembly is installed on the lower end face of the suspension assembly 3, and a marking line is installed on the upper end face of the limit ring 211. Both the camera assembly and the electric slider 312 are connected to the internal combustion engine assembly management system. The camera assembly transmits the captured position data of the internal combustion engine cylinder block 1 to the internal combustion engine assembly management system, and the electric slider 312 receives the position data transmitted by the internal combustion engine assembly management system and moves to the designated position.

[0076] The camera module uses an industrial camera, model PHX200S.

[0077] In use, the camera component transmits the captured position data of the internal combustion engine cylinder block 1 to the internal combustion engine assembly management system. Then, the internal combustion engine assembly management system analyzes the photos to understand the position of the marking line corresponding to the internal combustion engine cylinder block 1 and the position of the bearing installation position corresponding to the marking line. The system then sends the position of the bearing installation position corresponding to the marking line to the electric slider 312. The electric slider 312 changes position to be directly above the bearing and activates the marking light 3122 to mark the position.

[0078] The marking lines make it easy to identify the position of the internal combustion engine cylinder block 1 and the position of the bearings, which facilitates installation and improves performance.

[0079] A laser rangefinder 3121 is installed on one side of the electric slider 312. The laser rangefinder 3121 adopts the LR-T series. The laser rangefinder 3121 is mainly used to measure the position of the electric slider 312 to avoid the electric slider 312 from moving excessively and causing positional errors, thus ensuring the accuracy of the marking and good performance.

[0080] The lower end face of the electric slider 312 is equipped with an indicator light 3122 that can emit different colors of light.

[0081] The 3122 indicator light is a dual-color spotlight. When in use, the dual-color spotlight can emit light of different colors, illuminating the bearing positions on the main shaft hole of the internal combustion engine cylinder block 1. Assembly workers can install the bearings of the corresponding colors according to the color guide, avoiding installation errors and achieving good results.

[0082] This invention provides a visual error prevention device for bearing assembly based on light marking. No relevant personnel are required to make corrections during the entire bearing assembly process. It can realize the height adjustment of the internal combustion engine cylinder 1, the identification of the internal combustion engine cylinder 1, the identification of the position of the internal combustion engine cylinder 1, and the automatic adjustment and identification of the bearing markings. The whole process does not require on-site personnel to participate, which is highly efficient, highly intelligent, and has good use effect, and has good application prospects.

[0083] It should be noted that during use, the processed internal combustion engine cylinder block 1 is transported and placed on the support base 2. After the weighing sensor weighs it, it will send the weight data to the internal combustion engine assembly management system. At this time, the internal combustion engine assembly management system uses the threshold comparison method to achieve the initial identification of the internal combustion engine cylinder block 1, identify the shape of the internal combustion engine cylinder block 1, retrieve the corresponding adjustment data, generate an adjustment signal from the adjustment data and send it to the identification component 22. The identification component 22 receives the adjustment signal and scanning signal sent by the internal combustion engine assembly management system and identifies the QR code marked on the side of the internal combustion engine cylinder block 1.

[0084] The column lift is activated, which drives the identification plate to move, enabling the identification plate to recognize the QR code and feed the recognition result back to the internal combustion engine assembly management system. The internal combustion engine assembly management system retrieves the crankshaft QR code information that has been scanned in advance, and calculates the corresponding bearing installation type based on the internal combustion engine model and the crankshaft QR code information.

[0085] Simultaneously, the camera module transmits the captured position data of the internal combustion engine cylinder block 1 to the internal combustion engine assembly management system. The internal combustion engine assembly management system then analyzes the photos to determine the positions of the corresponding marking lines on the internal combustion engine cylinder block 1 and the bearing installation positions. The electric slider 312 receives the position data transmitted by the internal combustion engine assembly management system and moves to the designated position. The internal combustion engine assembly management system controls the indicator light 3122 to emit light of the corresponding color, illuminating the bearing installation positions on the main shaft hole of the internal combustion engine cylinder block 1. Assembly workers install the corresponding colored bearings according to the color guidance, avoiding installation errors and achieving good results.

[0086] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
