Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a coding tooling component. Background Technology

[0002] As the requirements for vehicle lightweighting and cost reduction and efficiency improvement continue to increase, vehicle chassis components are gradually shifting from traditional sheet metal stamping and welding to large-scale integrated aluminum alloy die casting. These die-cast parts are large in size and complex in structure, and are prone to local or overall deformation due to shrinkage stress during the demolding and cooling process, or even dimensional deviations (i.e., the workpiece's dimensions exceed the product's allowable tolerance range).

[0003] In current production processes, die casting is relatively fast (e.g., about 100 seconds), while dimensional inspection is typically located at the end of the production line. If deformed or out-of-tolerance parts are only detected at the end of the production line, it can easily lead to batch scrapping and huge economic losses. In addition, severely deformed parts are prone to interference with tooling fixtures during grinding, transfer, and other processes, resulting in the risk of production stoppage.

[0004] Because information such as the production date, batch number, and serial number needs to be marked on die-cast parts, marking fixtures are typically used to mark them after they are removed from the mold. However, existing marking fixtures only have positioning marking functions and cannot detect the deformation of the die-cast parts. Separate inspection fixtures require additional stations and inspection time, increasing production time and costs. While some solutions offer marking fixtures with pass / fail detection, they can only qualitatively determine whether the die-cast parts are out of tolerance and cannot accurately quantify the deformation, thus failing to provide precise data support for real-time adjustment of process parameters.

[0005] Therefore, there is an urgent need for an integrated chemical equipment that can simultaneously complete marking and positioning and precise and quantitative detection of deformation in key parts at the marking station immediately after the die-casting part is demolded. Utility Model Content

[0006] The purpose of this invention is to provide a coding fixture assembly to solve the problem that coding fixtures in related technologies cannot detect the deformation of workpieces, such as die castings.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This application provides a marking fixture assembly, which includes a marking fixture and a control system. The marking fixture includes a base plate and a displacement sensor. The displacement sensor is disposed on the base plate and includes a sensing part. The displacement sensor is configured to measure the amount of compression displacement of a first position of the workpiece relative to the sensing part. The first position is suitable for contact measurement. The control system is communicatively connected to the displacement sensor and is configured to: acquire and process the measurement data of the displacement sensor to determine the amount of deformation at the first position.

[0009] Based on the above-mentioned technical means, this application determines the deformation of the workpiece at a suitable position for contact measurement by setting up a displacement sensor and a control system, thereby achieving accurate quantification of the deformation of the workpiece.

[0010] Furthermore, since marking and positioning, as well as quantitative detection of deformation in key areas, can be completed simultaneously at the marking station adjacent to the workpiece after it leaves the mold, online, real-time detection and rapid feedback of deformation defects can be achieved.

[0011] In some embodiments, the marking fixture further includes a laser rangefinder mounted on a base plate. The laser rangefinder is configured to measure the distance between a second position of the workpiece and the optical center of the laser rangefinder, the second position being suitable for non-contact measurement. The control system is also communicatively connected to the laser rangefinder and is further configured to acquire and process measurement data from the laser rangefinder to determine the amount of deformation at the second position.

[0012] Based on the above technical means, the laser rangefinder and control system can determine the deformation of the workpiece at a position suitable for non-contact measurement, thus complementing the displacement sensor and enabling precise measurement of the deformation at different positions of the workpiece (positions suitable for contact and non-contact measurement), thereby determining the degree of deformation at multiple key points of the workpiece.

[0013] In some embodiments, the marking fixture includes at least one displacement sensor and at least one laser rangefinder, which are spaced apart at different positions on the base plate.

[0014] According to the above methods, at least one displacement sensor and at least one laser rangefinder can detect multiple different positions of the workpiece, thereby determining the degree of deformation of multiple key points of the workpiece.

[0015] Furthermore, the position, number, and type of at least one displacement sensor and at least one laser rangefinder are adaptable to be adjusted according to different workpieces. According to this technique, the position, number, and type of the displacement sensor and laser rangefinder on the base plate are adaptable to be adjusted according to the workpiece, so as to flexibly adapt to the detection needs of different workpieces.

[0016] In some embodiments, the marking fixture further includes a first base and a first column. The first base is detachably connected to a base plate, and the position of the first base on the base plate is adapted to be adjusted according to different workpieces. The first column is disposed on the first base. Along the height direction of the marking fixture, a displacement sensor is disposed at the end of the first column away from the first base.

[0017] According to the above-mentioned technical means, the displacement sensor is located at the end of the first column away from the first base, which can avoid interference between the displacement sensor and other components on the base plate, and facilitate the displacement sensor to measure the amount of compression displacement of the sensing part relative to the first position of the workpiece. In addition, by using the first base and the first column to achieve detachable connection of the displacement sensor to the base plate, direct contact with the displacement sensor can be avoided when adjusting the position of the displacement sensor, thereby protecting the displacement sensor.

[0018] In some embodiments, the marking fixture further includes a second base and a second column. The second base is detachably connected to the base plate, and the position of the second base on the base plate is adapted to be adjusted according to different workpieces. The second column is disposed on the second base, and along the height direction of the marking fixture, a laser rangefinder is disposed at the end of the second column away from the second base.

[0019] According to the aforementioned technical means, the laser rangefinder is positioned at the end of the second column away from the second base, which avoids interference between the laser rangefinder and other components on the base plate, and facilitates the measurement of the distance between the second position of the workpiece and the optical center of the laser rangefinder. Furthermore, by utilizing the second base and the second column to detachably connect the laser rangefinder to the base plate, direct contact with the laser rangefinder can be avoided when adjusting its position, thus protecting the laser rangefinder.

[0020] In some embodiments, the marking fixture further includes at least one guide portion, which is detachably connected to the base plate, and the position of the at least one guide portion on the base plate is adapted to be adjusted according to different workpieces, and the shape of the at least one guide portion corresponds to at least a portion of the contour of the workpiece.

[0021] According to the above-mentioned technical means, at least one guide part can play a guiding role in the initial placement of the workpiece on the marking fixture, thereby guiding the workpiece to a roughly suitable position. In addition, at least one guide part is detachably connected to the base plate, so that the position of at least one guide part on the base plate can be adjusted, thereby flexibly adapting to the guiding requirements of different workpieces.

[0022] In some embodiments, the marking fixture further includes at least one positioning part, which is detachably connected to the base plate. The position of the at least one positioning part on the base plate is adapted to be adjusted according to the different workpieces, and the at least one positioning part is configured to position the workpiece in the length and width directions of the marking fixture.

[0023] According to the above-mentioned technical means, at least one positioning part can provide precise positioning for the workpiece, and at least one positioning part is detachably connected to the base plate so as to adjust the position of at least one positioning part on the base plate, thereby flexibly adapting to the support and positioning requirements of different workpieces.

[0024] In some embodiments, the marking fixture further includes at least one support portion, which is detachably connected to the base plate. The position of the at least one support portion on the base plate is adapted to be adjusted according to the different workpieces. The height of the at least one support portion is adjustable and configured to support and position the workpiece in the height direction of the marking fixture.

[0025] According to the above-mentioned technical means, at least one positioning part and at least one supporting part can work together to ensure the precise positioning and stable support of the workpiece. Furthermore, at least one positioning part and at least one supporting part are detachably connected to the base plate, so that the positions of at least one positioning part and at least one supporting part on the base plate can be adjusted, thereby flexibly adapting to different workpiece support and positioning requirements.

[0026] In some embodiments, the marking fixture further includes at least one position sensor, which is disposed on at least one positioning part or at least one support part and is configured to detect the position of the workpiece.

[0027] Based on the aforementioned technical means, by setting a position sensor, it is possible to detect whether the workpiece is in the correct position. When the workpiece is in the correct position, the marking device receives the corresponding positioning signal and immediately begins marking the workpiece. Simultaneously, the deformation detection of at least one of the displacement sensor and the laser rangefinder is activated. Furthermore, by placing the position sensor in at least one positioning part or at least one support part, the occupancy of the base plate can be reduced, and there is no need to set up a separate support column for the position sensor, reducing the number of parts used and lowering costs.

[0028] In some embodiments, the coding fixture further includes at least one hoisting part, which is detachably connected to the base plate.

[0029] According to the above-mentioned technical means, by setting at least one hoisting part, the base plate and the components set on the base plate can be hoisted as a whole, thereby facilitating the movement of the coding tooling.

[0030] The beneficial effects of this utility model are:

[0031] (1) This application can achieve high integration of functions and online inspection. That is, it seamlessly integrates the precise positioning function of laser marking and the precise and quantitative detection function of deformation on a single tooling, realizing the simultaneous completion of "marking and inspection" at the laser marking station adjacent to the die casting mold after the die casting is completed, which greatly advances the inspection process to the front end of the production process and completely solves the problem of inspection lag.

[0032] (2) This application can achieve precise quantification of deformation. By combining two complementary measurement methods, displacement sensor (directly measuring displacement) and laser rangefinder (non-contact measuring distance), it can accurately quantify the specific deformation degree of multiple key points of the casting.

[0033] (3) This application can achieve rapid screening and accurate feedback: Based on the real-time acquisition of quantitative deformation data, it can immediately determine whether the casting is qualified and realize early rapid screening of out-of-tolerance parts; in addition, the accurate deformation data and its distribution can be directly used to guide the rapid and accurate adjustment and optimization of front-end die casting process parameters (such as holding pressure, cooling time, spraying amount, etc.) or tooling fixture status, significantly shortening the problem response cycle and avoiding blind adjustment.

[0034] (4) This application can effectively avoid batch losses and production stoppages: By timely detection and removal of deformed and out-of-tolerance parts at the source station (marking station), it effectively prevents the production line from being interrupted and the risk of batch scrapping caused by the continued flow of non-conforming products to subsequent processes. In addition, it avoids accidental production stoppages caused by collisions and interference between severely deformed parts and tooling in intermediate processes (such as deburring and grinding).

[0035] (5) This application can improve efficiency and reduce costs: it eliminates the need for independent testing stations, special inspection tools and corresponding operators, shortens the overall production process and cycle time, and significantly reduces testing costs and production costs.

[0036] (6) The structure of this application is flexible and highly adaptable. The position, quantity, and type of the displacement sensor assembly and the laser rangefinder assembly can be flexibly configured by adjusting the mounting position (connecting bolts) on the base plate according to the specific detection requirements of different workpieces, adapting to product changes and changes in detection points.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0048] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0049] In some embodiments, see Figure 1 This application provides a vehicle 1, which includes a body 101 and at least one wheel 102. The vehicle 1 also includes a chassis connected to the at least one wheel 102, and the chassis can be used to support the body 101. During the manufacturing process of the vehicle 1, at least one of the components of the vehicle 1 (e.g., parts belonging to the body 101 or chassis) needs to be marked with coding or other operations by a coding tooling assembly to mark information such as the generation date, batch number, and serial number.

[0050] In some embodiments, see Figure 2 This application provides a coding fixture assembly, which includes a coding fixture 10 and a control system 30. The control system 30 is communicatively connected to the coding fixture 10 to send signals to and receive signals sent by the coding fixture 10.

[0051] Please see Figure 3 and combined Figure 4 Embodiments of this application also include a coding device 22, which is located on one side of the coding fixture 10. The coding device 22 is configured to code the workpiece 21 (e.g., a die casting 21; hereinafter referred to as the die casting 21). For example, the coding device 22 includes a laser coding machine.

[0052] Please refer to Figure 4 and Figure 5The marking fixture 10 includes a base plate 11 and a displacement sensor assembly 12. The displacement sensor assembly 12 includes a displacement sensor 123, which is disposed on the base plate 11 and includes a sensing element 124. The displacement sensor 123 is configured to measure the amount of compressive displacement of a first position of the die-cast part 21 relative to the sensing element 124. For example, the displacement sensor 123 may be a contact displacement sensor. Here, the first position is suitable for contact measurement, that is, the displacement sensor 123 is suitable for a measurement point on the die-cast part 21 that can be safely contacted and compressed. The control system 30 is communicatively connected to the displacement sensor 123 and is configured to acquire and process the measurement data of the displacement sensor 123 to determine the amount of deformation at the first position.

[0053] For example, the sensing part 124 of the displacement sensor 123 is adapted to be compressed by the gravity of the die casting 21 when it is placed in place, and the amount of deformation of the corresponding point (i.e., the first position) of the die casting 21 is determined by detecting the amount of compression displacement of the sensing part 124.

[0054] Specifically, when the die-cast part 21 is placed in position, its weight directly acts on the sensing part 124 of the displacement sensor 123, causing it to generate axial compression displacement. The sensor 123 internally converts the displacement into a corresponding electrical signal, which, after being processed by the signal conditioning circuit, yields the displacement deviation value of the actual position of the measurement point relative to the preset standard position, that is, the deformation amount of the die-cast part 21 at the first position.

[0055] According to the marking tooling assembly of the present disclosure, the displacement sensor 123 can determine the amount of deformation of the die casting 21 at a position suitable for contact measurement, thereby realizing the accurate quantification of the amount of deformation of the die casting 21.

[0056] Furthermore, since marking and positioning and quantitative detection of deformation of key parts (such as the first position mentioned above) can be completed simultaneously at the marking station adjacent to the die casting part 21 after it exits the mold, online, real-time detection and rapid feedback of deformation defects can be achieved.

[0057] In some embodiments, please refer to Figure 4 and Figure 5 The marking fixture 10 also includes a laser rangefinder assembly 18, which includes a laser rangefinder 183 mounted on the base plate 11. The laser rangefinder 183 is configured to measure the distance between a second position of the die-cast part 21 and the optical center of the laser rangefinder 183. Here, the second position is suitable for non-contact measurement; that is, the laser rangefinder 183 is suitable for use at points with limited space, fragile surfaces, or where non-contact measurement is required. The control system 30 is also communicatively connected to the laser rangefinder 183 and is further configured to acquire and process the measurement data from the laser rangefinder 183 to determine the amount of deformation at the second position.

[0058] For example, the laser rangefinder 183 is adapted to emit and receive reflected laser light at a pre-set key measurement point on the surface of the die casting 21, and measure the distance change of the corresponding point on the die casting by calculating the optical path difference.

[0059] Specifically, the laser rangefinder 183 emits a modulated laser beam toward a pre-set key measurement point (i.e., the second position) on the surface of the die-cast part 21, and receives the laser beam reflected back from that point. Internally, the laser rangefinder 183 calculates the time difference between the emitted and received reflected light, and, in conjunction with the speed of light constant, accurately calculates the actual distance from the optical center of the laser rangefinder 183 to the measurement point on the surface of the casting. The control system 30 compares this actual distance with a preset standard distance value to obtain the distance deviation value at that point, i.e., the deformation amount at the second position of the die-cast part 21.

[0060] According to the marking tooling assembly of this disclosure, the laser rangefinder 183 and the control system can determine the deformation amount of the die casting 21 at a position suitable for non-contact measurement, so as to complement the displacement sensor 123, and realize the precise measurement of the deformation amount of the die casting 21 at different positions (positions suitable for contact measurement and non-contact measurement), thereby determining the degree of deformation of multiple key points of the die casting 21.

[0061] In some embodiments, the data processing and judgment process is as follows: The control system 30 collects and processes measurement data from the displacement sensor 123 and the laser rangefinder 183 in real time, and compares these quantified data with pre-stored standard values ​​and allowable tolerance ranges. It should be noted that the measurement data from the displacement sensor 123 and the measurement data from the laser rangefinder 183 correspond to different pre-stored standard values ​​and allowable tolerance ranges; therefore, they should be compared separately. Based on the comparison results, the control system 30 can output a judgment in real time: for example, whether the die-cast part 21 as a whole or its key parts are qualified, and record and / or display specific quantified deformation data. For parts that exceed tolerances, an alarm can be immediately triggered or a production line notification can be sent offline.

[0062] In some embodiments, please refer to Figure 4 and Figure 5 The displacement sensor assembly 12 also includes a first base 121 and a first column 122. The first base 121 is detachably connected to the base plate 11. For example, the first base 121 is provided on the base plate 11 via a connecting part 16 (e.g., bolt). The position of the first base 121 on the base plate 11 is adapted to be adjusted according to the die-cast part 21. The first column 122 is provided on the first base 121. Along the height direction Z of the marking fixture 10, the displacement sensor 123 is provided at the end of the first column 122 away from the first base 121.

[0063] According to the displacement sensor assembly 12 of this disclosure, the displacement sensor 123 is disposed at the end of the first column 122 away from the first base 121. This avoids interference between the displacement sensor 123 and other components on the base plate 11, and facilitates the displacement sensor 123 in measuring the amount of compression displacement of the first position of the die-cast part 21 relative to the sensing part 124. Furthermore, by utilizing the first base 121 and the first column 122 to detachably connect the displacement sensor 123 to the base plate 11, direct contact with the displacement sensor 123 can be avoided when adjusting its position, thereby protecting the displacement sensor 123.

[0064] In some embodiments, please refer to Figure 4 and Figure 6 The laser rangefinder assembly 18 also includes a second base 181, a second column 182, and a first bracket 184. The second base 181 is detachably connected to the base plate 11. For example, the second base 181 is mounted on the base plate 11 via a connecting part 16 (e.g., a bolt). The position of the second base 181 on the base plate 11 is adapted to be adjusted according to the die-cast part 21. The second column 182 is mounted on the second base 181 along the height direction Z of the marking fixture 10. The laser rangefinder 183 is mounted on the end of the second column 182 away from the second base 181. For example, the laser rangefinder 183 is detachably mounted on the end of the second column 182 away from the second base 181 via the first bracket 184.

[0065] According to the laser rangefinder assembly 18 of this disclosure, the laser rangefinder 183 is disposed at the end of the second column 182 away from the second base 181. This avoids interference between the laser rangefinder 183 and other components on the base plate 11, and facilitates the laser rangefinder 183 in measuring the distance between the second position of the die-cast part 21 and the optical center of the laser rangefinder 183. Furthermore, by utilizing the second base 181 and the second column 182 to detachably connect the laser rangefinder 183 to the base plate 11, direct contact with the laser rangefinder 183 can be avoided when adjusting its position, thereby protecting the laser rangefinder 183.

[0066] In some embodiments, the marking fixture 10 includes at least one displacement sensor (e.g., four displacement sensors) and at least one laser rangefinder 123 (e.g., one laser rangefinder). These displacement sensors 123 and laser rangefinders are spaced apart at different positions on the base plate 11 to detect multiple different positions of the workpiece, thereby determining the degree of deformation at multiple key points of the workpiece.

[0067] In some embodiments, the position, number, and type of displacement sensor 123 and laser rangefinder 183 are adapted to be adjusted according to the die casting 21.

[0068] For example, the displacement sensor assembly 12 and the laser rangefinder assembly 18 are adjustablely mounted on the corresponding positions of the base plate 11 via the connecting part 16, according to the position distribution of the key points to be detected (e.g., the first position and the second position) of the die-cast part 21 and the requirements of the detection method.

[0069] For example, the position, quantity, and type (such as sensors with different ranges or accuracies) of the sensor assembly 12 and the laser rangefinder assembly 18 can be conveniently adjusted and installed on the grid holes of the base plate 11 or the preset installation area by loosening and retightening the connection part 16 according to the specific detection requirements of different die-cast parts 21.

[0070] Based on the above technical means, the positions of the displacement sensor 12 and the laser rangefinder 18 on the base plate 11, as well as the number and type of the displacement sensor 12 and the laser rangefinder 18, can be adjusted according to the die casting 21 to flexibly adapt to the detection requirements of different die castings 21.

[0071] In some embodiments, please refer to Figure 4 The marking fixture 10 also includes at least one guide portion 13. In this embodiment, for example, four guide portions 13 are included. In other embodiments, two, three, five, or other numbers of guide portions 13 may be included. The guide portion 13 is detachably connected to the base plate 11. For example, the guide portion 13 is provided on the base plate 11 through a connecting portion 16, and the position of the guide portion 13 on the base plate 11 is adapted to be adjusted according to the die-cast part 21. The shape of the guide portion 13 corresponds to at least a portion of the outline of the die-cast part 21.

[0072] According to the marking fixture 10 of this disclosure, the guide portion 13 can play a guiding role in the initial placement of the die-cast part 21 on the marking fixture 10, thereby guiding the die-cast part 21 to be approximately in a suitable position. In addition, the guide portion 13 is detachably connected to the base plate 11 so that the position of the guide portion 13 on the base plate 11 can be adjusted, thereby flexibly adapting to the guiding requirements of different die-cast parts 21.

[0073] In some embodiments, please refer to Figure 4The marking fixture 10 also includes at least one positioning part 15 and at least one support part 17. In this embodiment, it includes four positioning parts 15, four first support parts 171, and two second support parts 172. Here, the height of the first support part 171 is different from the height of the second support part 172; for example, the height of the first support part 171 is greater than the height of the second support part 172. In other embodiments, it may also include two, three, five, or other numbers of positioning parts 15 or support parts 17. In some embodiments, the positioning part 15 includes a positioning pin, the positioning part 15 is detachably connected to the base plate 11, the position of the positioning part 15 on the base plate 11 is adapted to be adjusted according to the die-cast part 21, and the positioning part 15 is configured to precisely position the die-cast part 21 in the length direction X and the width direction Y of the marking fixture 10.

[0074] The support portion 17 is detachably connected to the base plate 11. For example, the support portion 17 includes a support block. The position of the support portion 17 on the base plate 11 is adapted to be adjusted according to the die-cast part 21. The height of the support portion 17 can be adjusted or designed according to different die-cast parts 21. The support portion 17 is configured to support and position the die-cast part 21 in the height direction Z of the marking fixture 10. The support portion 17 is arranged in the key support area on the bottom surface of the die-cast part 21, providing Z-axis support and positioning. For large thin-walled aluminum alloy castings, it can also effectively prevent additional deformation caused by its own weight. It should be noted that the guide portion 13, the positioning portion 15, and the support portion 17 together constitute the positioning and support system of the die-cast part 21.

[0075] According to the marking fixture 10 of this disclosure, the positioning part 15 and the support part 17 can work together to ensure the accurate positioning and stable support of the die-cast part 21. Furthermore, the positioning part 15 and the support part 17 are detachably connected to the base plate 11, and the height of the support part 17 is adjustable to adjust the positions of the positioning part 15 and the support part 17 on the base plate 11, thereby flexibly adapting to different support and positioning requirements of the die-cast part 21.

[0076] It should be noted that all functional components (such as displacement sensor assembly 12, guide part 13, positioning part 15, support part 17 and laser ranging assembly 18) are detachably fixed to the base plate 11 through the connecting part 16, so as to facilitate the adjustment of the layout according to the positioning, support and detection requirements of different models of die-cast parts 21.

[0077] In some embodiments, please refer to Figure 4The coding fixture 10 also includes at least one position sensor 19 and at least one second bracket 20. In this embodiment, it includes two position sensors 19 and two second brackets 20. In other embodiments, it may include three, four, five, or other numbers of position sensors 19 and second brackets 20. The position sensors 19 are mounted on the positioning part 15 or the support part 17 via the second brackets 20. Figure 4 Taking the position sensor 19 located in the positioning section 15 as an example, the position sensor 19 is configured to detect the position of the die-cast part 21. For example, the position sensor 19 is configured to detect whether the die-cast part 21 is placed in the correct position and trigger the marking and detection program.

[0078] For example, during operation, a part-picking robot typically grips the die-cast part 21 to be processed and places it onto a tooling fixture. During placement, the guide part 13 guides the casting part into position, and then the positioning part 15 and the support part 17 work together to ensure precise positioning and stable support of the die-cast part 21. Once the die-cast part 21 is in place and stable, the position sensor 19 is triggered by gravity. After the positioning signal is triggered, the marking device 22 receives the signal and immediately begins laser marking the die-cast part 21, while the deformation detection program integrated into the marking fixture assembly is simultaneously activated.

[0079] According to the marking fixture 10 of this disclosure, by setting a position sensor 19, it is possible to detect whether the die-cast part 21 is in position. When the die-cast part 21 is in position, the marking device 22 receives the corresponding position signal and immediately starts marking the die-cast part 21. At least one of the displacement sensor 12 and the laser rangefinder 18 simultaneously starts detecting the deformation. In addition, by setting the position sensor 19 on the positioning part 15 or the support part 17, the occupation of the base plate 11 can be reduced, and there is no need to set a separate column to support the position sensor 19, reducing the number of parts used and lowering costs.

[0080] In some embodiments, please refer to Figure 4 The coding fixture 10 also includes at least one hoisting part 14. In this embodiment, four hoisting parts 14 are included. In other embodiments, two, three, five, or other numbers of hoisting parts 14 may be included. The hoisting part 14 is detachably connected to the base plate 11. For example, the hoisting part 14 includes a lifting ring. The hoisting part 14 is installed on the base plate 11 by a threaded connection and is used for the overall hoisting of the coding fixture 10.

[0081] According to the coding fixture 10 of the present disclosure, by providing the hoisting part 14, the base plate 11 and the components provided on the base plate 11 can be hoisted as a whole, thereby facilitating the movement of the coding fixture 10.

[0082] The marking tooling assembly according to the embodiments of this disclosure can achieve high functional integration and online inspection. That is, the precise positioning function of laser marking and the precise and quantitative detection function of deformation are seamlessly integrated on a single tooling, realizing "marking and inspection" to be completed simultaneously at the laser marking station adjacent to the die casting mold after the die casting is completed. This significantly advances the inspection process to the front end of the production process and completely solves the problem of inspection lag.

[0083] According to the marking tooling assembly of the present disclosure, the deformation amount can be accurately quantified. By combining two complementary measurement methods, displacement sensor (directly measuring displacement) and laser rangefinder (non-contact measuring distance), the specific deformation degree of multiple key points of the casting can be accurately quantified.

[0084] According to the coding tooling component of the present disclosure, rapid screening and accurate feedback can be achieved: based on the real-time acquired quantitative deformation data, it is possible to immediately determine whether the casting is qualified, and realize early rapid screening of out-of-tolerance parts; in addition, the accurate deformation data and its distribution can be directly used to guide the rapid and accurate adjustment and optimization of front-end die casting process parameters (such as holding pressure, cooling time, spraying amount, etc.) or tooling fixture status, significantly shortening the problem response cycle and avoiding blind adjustments.

[0085] The coding tooling assembly according to the embodiments of this disclosure can effectively avoid batch losses and production stoppages: by timely detection and rejection of deformed and out-of-tolerance parts at the source station (coding station), it effectively prevents the production line from being interrupted and the risk of batch scrapping caused by the continued flow of defective products to subsequent processes. In addition, it avoids accidental production stoppages caused by collisions and interference between severely deformed parts and the tooling in intermediate processes (such as deburring and grinding).

[0086] The coding tooling assembly according to the embodiments of this disclosure can improve efficiency and reduce costs: it eliminates the need for independent inspection stations, special inspection tools and corresponding operators, shortens the overall production process and cycle time, and significantly reduces inspection and production costs.

[0087] The marking fixture assembly according to the embodiments of this disclosure has a flexible and highly adaptable structure. The position, quantity, and type of the displacement sensor assembly and the laser rangefinder assembly can be flexibly configured by adjusting the mounting position (connecting bolts) on the base plate according to the specific inspection requirements of different die-cast parts, adapting to product changes and changes in inspection points.
