Description

Technical Field

[0001] This invention relates to the field of wear plate processing, and more specifically, to a wear plate processing production line. Background Technology

[0002] Wear plates are critical and easily damaged parts in railway freight car bogie systems. Each freight car requires dozens to hundreds of wear plates, depending on the bogie type. The bogie is the load-bearing and moving structure of the freight car, and the wear plates are installed on the contact surfaces between the bogie frame and various moving parts, serving to buffer friction and protect the base structure. When the wear plates reach their wear limit, they must be replaced promptly to ensure the safe operation of the bogie. Therefore, although small, wear plates directly affect the operational safety, smoothness, and maintenance cycle of railway freight cars.

[0003] In related technologies, the production of wear plates generally adopts a discrete production mode of manual single-machine operation and semi-automatic auxiliary equipment. In the production process of wear plates, drilling, countersinking, tenoning, inspection and other processes are often completed separately by multiple related companies.

[0004] Therefore, the production efficiency of wear plates in related technologies is low and the production cycle is long. Summary of the Invention

[0005] The main objective of this invention is to provide a wear plate processing production line to solve the problems of low production efficiency and long production cycle of wear plates in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a wear plate processing production line is provided, comprising: a production line track extending along a first transverse direction; a machining center located on a first side of the production line track in a second transverse direction perpendicular to the first transverse direction; a material docking station located on a second side opposite to the first side of the production line track in the second transverse direction, the material docking station including a blank docking station and a finished product docking station, the blank docking station and the finished product docking station being arranged at intervals along the first transverse direction; an inter-sequence workpiece waiting station disposed at a first end of the production line track in the first transverse direction; and a lettering device located in the first transverse direction. The lettering device is located on one side of the machining center and is set at the first end of the production line track; the first transfer robot is movably set on the production line track along the first transverse direction. The first transfer robot has a first picking position that cooperates with the blank docking table, a first feeding position that cooperates with the finished product docking table or the inter-sequence workpiece waiting table, and a first loading and unloading position that cooperates with the machining center; the second transfer robot is located on the side of the inter-sequence workpiece waiting table away from the production line track in the first transverse direction. The second transfer robot has a second picking position that cooperates with the inter-sequence workpiece waiting table, a second feeding position that cooperates with the finished product docking table, and a second loading and unloading position that cooperates with the lettering device.

[0007] Furthermore, the wear plate processing production line also includes a vision recognition device and a control unit. The vision recognition device and the control unit are connected by signals, and the control unit controls the machining center and the first transfer robot to work according to the recognition information of the vision recognition device.

[0008] Furthermore, the visual recognition device includes a crossbeam, two columns, a drive unit, and a camera. The two columns are respectively arranged on both sides of the blank docking platform along the first transverse direction. The two ends of the crossbeam are respectively fixedly connected to the upper ends of the two columns. The crossbeam is located above the blank docking platform. The drive unit is driven by the camera to drive the camera to move on the crossbeam. The camera is signal-connected to the control unit.

[0009] Furthermore, the wear plate processing production line also includes a central control system. The machining center, lettering equipment, vision recognition equipment 80, first transfer robot and second transfer robot are respectively connected to the central control system via signals. The central control system includes control components.

[0010] Furthermore, the machining center includes a tooling base plate, a positioning mechanism, and a clamping mechanism. Both the positioning mechanism and the clamping mechanism are set on the tooling base plate to achieve the positioning and clamping of the wear plate workpiece on the tooling base plate.

[0011] Furthermore, the positioning mechanism includes a positioning block, a side push plate, and a side push cylinder arranged sequentially along the second transverse direction. The positioning block and the side push cylinder are both fixedly mounted on the tooling base plate, and the side push plate is movably mounted on the tooling base plate along the second transverse direction. The side push plate is drivenly connected to the side push cylinder.

[0012] Furthermore, the clamping mechanism includes a first clamp and a second clamp; the first clamp includes a synchronizing cylinder and two clamping plates. The synchronizing cylinder is fixedly mounted on the tooling base plate, and the two clamping plates are symmetrically arranged on both sides of the positioning mechanism in the first transverse direction. The synchronizing cylinder is driven to drive the clamping plates, and the synchronizing cylinder drives the two clamping plates to move closer or further away from each other; the second clamp includes an upper pressure block and a driving cylinder. The upper pressure block is located above the clamping plates in the vertical direction, and the driving cylinder is fixedly mounted on the tooling base plate. The driving cylinder is driven to drive the upper pressure block. The upper pressure block has a pressing position and a clearance position. When the upper pressure block is in the pressing position, the projection of the upper pressure block on the tooling base plate is located between the projections of the two clamping plates on the tooling base plate. When the upper pressure block is in the clearance position, the projection of the upper pressure block on the tooling base plate is located on the side of the projections of the two clamping plates on the tooling base plate in the transverse direction.

[0013] Furthermore, the upper pressure block includes a pressure strip, and the driving cylinder includes a corner cylinder. One end of the pressure strip is fixedly connected to the corner cylinder, and the corner cylinder is rotatably mounted on the tooling base plate around its vertical axis. The clamping mechanism includes two positioning mechanisms and two first clamps arranged in a one-to-one correspondence. The two first clamps are spaced apart in the first transverse direction, and the corner cylinder is located between the two first clamps in the first transverse direction. When the upper pressure block is in the pressing position, the extension direction of the pressure strip is parallel to the first transverse direction, and the projections of the two ends of the pressure strip on the tooling base plate are respectively located between the projections of the two clamping plates of the corresponding first clamps on the tooling base plate. When the upper pressure block is in the clearance position, the projection of the pressure strip on the tooling base plate is located between the projections of the two first clamps on the tooling base plate in the transverse direction.

[0014] Furthermore, the wear plate processing production line also includes an AGV vehicle and multiple guide frames, which are spaced apart in the first transverse direction. The gap between two adjacent guide frames forms a placement space for placing a blank docking table or a finished product docking table. The wear plate processing production line also includes an anti-collision mechanism, which is connected to the AGV vehicle via a signal.

[0015] Furthermore, the wear plate processing production line also includes a manual inspection slide, which is set at the second end of the production line track in the first transverse direction.

[0016] Applying the technical solution of this invention, a first transfer robot is movably mounted on the production line track along a first lateral direction. It is responsible for transferring wear-resistant plate workpieces between the blank docking station, the machining center, the inter-process workpiece waiting station, or the finished product docking station. The first transfer robot can pick up wear-resistant plate workpieces from the blank docking station, load and unload them to the machining center, and transport the processed wear-resistant plate workpieces to the finished product docking station or the inter-process workpiece waiting station. A second transfer robot is located on the side of the inter-process workpiece waiting station away from the production line track. It is responsible for transferring wear-resistant plate workpieces between the inter-process workpiece waiting station, the lettering equipment, and the finished product docking station. It can pick up wear-resistant plate workpieces from the inter-process workpiece waiting station, load and unload them to the lettering equipment, and transport the lettered wear-resistant plate workpieces to the finished product docking station. For wear plate workpieces that do not require lettering, the first transfer robot directly picks them up and places them on the finished product docking table after processing at the machining center, thus achieving rapid transfer of the wear plate workpieces. For wear plate workpieces that require lettering, the first transfer robot transports them to the inter-process workpiece waiting table for temporary storage, and then the second transfer robot picks them up and sends them to the lettering equipment. The lettering equipment includes a slider, a lettering fixture, and an inductive switch detection device set on the lettering fixture. After the inductive switch detection device on the lettering fixture automatically detects that the wear plate workpiece is in place, it controls the slider to descend and press the mark. After completion, the slider returns, and the second transfer robot picks up the finished wear plate and sends it to the finished product docking table. Through the cooperation between the various components on the wear plate processing production line in this embodiment, the entire process of automated continuous production from loading, processing, lettering to unloading of wear plate workpieces is realized, which greatly shortens the production cycle, significantly improves production efficiency, and reduces the number of production personnel and manual labor dependence. It can effectively solve the problems of low production efficiency and long production cycle of wear plates in related technologies. Attached Figure Description

[0037] Wear plates are critical and easily damaged parts in railway freight car bogie systems. Each freight car requires dozens to hundreds of wear plates, depending on the bogie type. As the core load-bearing and running device under the railway freight car, the bogie has wear plates installed on the contact surfaces between its moving parts and the frame, primarily serving to buffer friction and protect the base structure. When the wear plates wear to their limit, they must be replaced promptly to ensure the safe operation of the bogie. Therefore, although small, wear plates directly affect the operational safety, smoothness, and maintenance cycle of railway freight cars. Furthermore, railway freight car wear plates are characterized by a wide variety and high demand, placing higher demands on production efficiency and quality consistency.

[0038] However, the applicant discovered that in the relevant technologies, the production mode of wear plates is usually a discrete production mode. Taking the typical production route of 45 steel wear plates as an example, its process mainly includes: wear plate workpiece preparation, drilling, countersinking, tenoning, lettering, and inspection. In actual production, the above-mentioned drilling, countersinking, tenoning, lettering, and inspection processes are often completed by different related enterprises or different workshops. The entire process of production requires the cooperation of multiple enterprises.

[0039] Because the production processes for wear plates in related technologies are dispersed, wear plate workpieces need to be transported and stored over long distances between processes, resulting in long transportation cycles, low production efficiency, and high transportation costs. Furthermore, there are more than a dozen specifications for wear plates, with overlapping processes and diverse operating equipment. The production process of wear plates in related technologies is highly dependent on manual operation, and the varying skill levels of different operators lead to weak quality assurance capabilities and difficulty in controlling the consistency of product dimensional accuracy and surface quality. In addition, there are frequent instances of blame-shifting due to quality issues between upstream and downstream processes, which is detrimental to the standardization of production management. Moreover, during manual operations such as drilling, countersinking, mortising, and lettering, operators need to be in close contact with high-speed rotating tools or high-pressure hydraulic equipment, posing certain personal safety risks.

[0040] To solve the above problems, such as Figures 1 to 3 As shown, this embodiment of the invention provides a wear plate processing production line, which includes a production line track 10, a machining center 20, a material docking station 30, an inter-sequence workpiece waiting station 40, a lettering device 50, a first transfer robot 60, and a second transfer robot 70. The production line track 10 extends along a first transverse direction. In a second transverse direction perpendicular to the first transverse direction, the machining center 20 is located on a first side of the production line track 10. In the second transverse direction, the material docking station 30 is located on a second side opposite to the first side of the production line track 10. The material docking station 30 includes a blank docking station 31 and a finished product docking station 32, which are arranged at intervals along the first transverse direction. In the first transverse direction, the inter-sequence workpiece waiting station 40 is located corresponding to the first end of the production line track 10. In the first transverse direction, the lettering device 50 is located on one side of the machining center 20, and the lettering device 50 also corresponds to the first end of the production line track 10. At one end, a first transfer robot 60 is movably mounted on the production line track 10 along a first transverse direction. The first transfer robot 60 has a first picking position that cooperates with the blank docking table 31, a first feeding position that cooperates with the finished product docking table 32 or the inter-sequence workpiece waiting table 40, and a first loading / unloading position that cooperates with the machining center 20. In the first transverse direction, a second transfer robot 70 is located on the side of the inter-sequence workpiece waiting table 40 away from the production line track 10. The second transfer robot 70 has a second picking position that cooperates with the inter-sequence workpiece waiting table 40, a second feeding position that cooperates with the finished product docking table 32, and a second loading / unloading position that cooperates with the lettering device 50.

[0041] The wear plate processing production line provided in this embodiment has a production line track 10 extending along a first transverse direction. A machining center 20 is located on the first side of the production line track 10. In the second transverse direction, a material docking station 30 is located on the second side opposite to the first side of the production line track 10. A blank docking station 31 and a finished product docking station 32 are arranged at intervals along the first transverse direction. An inter-sequence workpiece waiting station 40 is set at the first end of the production line track 10. In the first transverse direction, a lettering device 50 is located on one side of the machining center 20, and the lettering device 50 is also set at the first end of the production line track 10. The above layout realizes a reasonable and compact layout and efficient use of space in the wear plate processing production line. This makes the feeding, processing, inter-sequence temporary storage, and output of finished wear plate workpieces form a clear material flow line on the wear plate processing production line, effectively reducing the ineffective movement distance of wear plate workpieces in the processing production line.

[0042] Furthermore, a first transfer robot 60 is movably mounted on the production line track 10 along a first lateral direction, and is responsible for transferring the wear plate workpiece between the blank docking table 31, the machining center 20, the inter-process workpiece waiting table 40, or the finished product docking table 32. The first transfer robot 60 can pick up the wear plate workpiece from the blank docking table 31, load and unload it to the machining center 20, and transport the processed wear plate workpiece to the finished product docking table 32 or the inter-process workpiece waiting table 40. A second transfer robot 70 is located on the side of the inter-process workpiece waiting table 40 away from the production line track 10, and is responsible for transferring the wear plate workpiece between the inter-process workpiece waiting table 40, the lettering equipment 50, and the finished product docking table 32. It can pick up the wear plate workpiece from the inter-process workpiece waiting table 40, load and unload it to the lettering equipment 50, and transport the lettered wear plate workpiece to the finished product docking table 32. For wear plate workpieces that do not require lettering, the first transfer robot 60 directly picks them up and places them on the finished product docking table 32 after processing in the machining center 20, thus achieving rapid transfer of the wear plate workpieces. For wear plate workpieces that require lettering, the first transfer robot 60 transports them to the inter-process workpiece waiting table 40 for temporary storage, and then the second transfer robot 70 picks them up and sends them to the lettering equipment 50. The lettering equipment 50 includes a slider, a lettering fixture, and an inductive switch detection device set on the lettering fixture. After the inductive switch detection device on the lettering fixture automatically detects that the wear plate workpiece is in place, it controls the slider to descend and press the mark. After completion, the slider returns, and the second transfer robot 70 picks up the finished wear plate and sends it to the finished product docking table 32. Through the coordination between various components on the wear plate processing production line in this embodiment, the entire process of automatic continuous production of wear plate workpieces from loading, processing, lettering to unloading is realized, which greatly shortens the production cycle, significantly improves production efficiency, and reduces the number of production personnel and manual labor dependence. It can effectively solve the problems of low production efficiency and long production cycle of wear plates in related technologies.

[0043] It should be noted that, in a preferred embodiment, the first transfer robot 60 is preferably a six-axis robot. The six-axis robot has high flexibility and freedom, and can adapt to the placement posture of the wear plate workpiece on the blank docking table 31, as well as meet the loading and unloading requirements of the tooling base plate 21 in the machining center 20, so as to ensure the accuracy of gripping and placing the wear plate workpiece.

[0044] Meanwhile, in order to enable the first transfer robot 60 to move long distances and with high precision along the extension direction (i.e., the first lateral direction) of the production line track 10, the wear plate processing production line in this embodiment also includes a slide saddle and a slide saddle drive. The first transfer robot 60 is fixedly mounted on the slide saddle, which is slidably set on the production line track 10. The production line track 10 is a rack and pinion guide rail. The slide saddle cooperates with the production line track 10 through gear meshing or other means. The slide saddle drive can be a servo motor with a lead screw or rack and pinion, or a direct drive motor, etc., thereby carrying the first transfer robot 60 mounted on it to move back and forth between the blank docking table 31, the machining center 20, the inter-sequence workpiece waiting table 40, and the finished product docking table 32. The production line track 10 adopts a semi-enclosed protective structure. The rack and pinion guide rail does not have high-temperature thermal deformation, is easy to maintain, and does not require additional workpiece transfer trolleys and manual handling equipment.

[0045] It should be noted that, in a preferred embodiment, the second transfer robot 70 is preferably a six-axis industrial robot, capable of adapting to the loading and unloading needs between the inter-sequence workpiece waiting table 40, the lettering device 50, and the finished product docking table 32, ensuring the accuracy and stability of gripping the wear plate workpiece. To achieve stable operation of the second transfer robot 70, the wear plate processing production line also includes a column. The second transfer robot 70 is fixedly mounted on the column, which is vertically positioned on the ground or a base. The base of the second transfer robot 70 is fastened to the top of the column via a flange or bolts, thereby ensuring that the working space of the second transfer robot 70 is relatively independent and structurally stable. The coverage area of ​​the second transfer robot 70 mainly includes the area where the inter-sequence workpiece waiting table 40, the lettering device 50, and the finished product docking table 32 are located.

[0046] It should be noted that a single machining center 20 can complete all milling processes, including drilling, chamfering, and milling tenons. In a preferred embodiment, to further achieve efficient and continuous automated production, the wear plate processing production line includes three machining centers 20, which are arranged in a line along the extension direction of the production line track 10. Furthermore, to ensure processing quality and efficiency, the machining center 20 includes a non-contact tool breakage detection device. This device rapidly detects the length and breakage condition of the tool using a non-contact method, such as a laser probe or a pneumatic probe, before each cutting operation or after tool replacement, thus preventing batch scrap due to tool damage.

[0047] It should be noted that the lettering device 50 includes a two-way cartridge valve hydraulic system. Because the two-way cartridge valve hydraulic system has good valve core damping and response characteristics, it enables smooth slider operation with low noise. In the working circuit of the lettering device 50, by controlling the opening and closing state of the two-way cartridge valve, the flow direction, flow rate, and pressure of the hydraulic oil are precisely controlled, thereby driving the slider to perform downward pressing, pressure holding, and return actions. Furthermore, during the lettering process, the slider can descend at a stable speed and apply constant pressure, avoiding problems such as inconsistent marking depth, skewness, or blurriness caused by hydraulic shock or pressure fluctuations.

[0048] It should be noted that the workpiece waiting platform 40 is arranged in two ways at the first end of the production line track 10. The first arrangement is that the workpiece waiting platform 40 is set on the first end of the corresponding production line track 10. The second arrangement is that there is a certain gap between the workpiece waiting platform 40 and the first end of the corresponding production line track 10.

[0049] It should be noted that, as Figure 1 and Figure 2 As shown, the first horizontal direction is the X direction, and the second horizontal direction is the Y direction.

[0050] like Figure 3 As shown, the wear plate processing production line also includes a vision recognition device 80 and a control unit. The vision recognition device 80 is connected to the control unit by signal. The control unit controls the machining center 20 and the first transfer robot 60 to work according to the recognition information of the vision recognition device 80. By setting up the vision recognition device 80 and the control unit, the automation level and production adaptability of the wear plate processing production line are effectively improved.

[0051] Specifically, the visual recognition device 80 is signal-connected to the control unit, and performs image acquisition and analysis on the wear plate workpiece on the blank docking table 31. Based on the type, position, and spatial posture of the wear plate workpiece identified by the visual recognition device 80, the data is transmitted to the control unit. According to the visual recognition results, the control unit adjusts the gripping path, end effector posture, and gripping point coordinates of the first transfer robot 60, thereby guiding the first transfer robot 60 to accurately grip the wear plate workpiece. This effectively solves the risk of gripping failure or collision caused by the random placement and inconsistent posture of the blank workpiece on the blank docking table 31, and reduces the reliance on manual loading.

[0052] Furthermore, the control unit can match and call the corresponding processing program of the machining center 20 according to the wear plate specifications identified by the vision recognition device 80, ensuring that the processing parameters of wear plates of different specifications are accurate in drilling, milling and other processes, avoiding batch scrap caused by manual workpiece selection error or program call error, so that the same wear plate processing production line can be compatible with the production of more than a dozen different specifications of wear plates, and there is no need to frequently stop the machine to adjust the equipment, thus improving the adaptability and production efficiency of the wear plate processing production line to different specifications of wear plates.

[0053] like Figure 3 As shown, the visual recognition device 80 includes a crossbeam 81, two columns 82, a drive unit 83, and a camera 84. The two columns 82 are respectively arranged on both sides of the blank docking platform 31 along the first transverse direction. The two ends of the crossbeam 81 are respectively fixedly connected to the upper ends of the two columns 82. The crossbeam 81 is located above the blank docking platform 31. The drive unit 83 is drivenly connected to the camera 84 to drive the camera 84 to move on the crossbeam 81. The camera 84 is signal connected to the control unit.

[0054] In this embodiment, the visual recognition device 80 consists of a crossbeam 81, columns 82, a drive unit 83, and a camera 84. The visual recognition device 80 performs efficient and stable visual recognition of the wear plate workpiece on the blank docking table 31. Specifically, two columns 82 are respectively arranged on both sides of the blank docking table 31 along the first transverse direction, and the two ends of the crossbeam 81 are fixedly connected to the upper ends of the two columns 82 to form a stable gantry structure, ensuring the stability of the camera 84 during operation and effectively avoiding image blurring or recognition errors caused by vibration.

[0055] Furthermore, the drive unit 83 drives the camera 84 to move along the crossbeam 81, enabling the camera 84 to cover the working area of ​​the blank docking table 31. When using the camera 84 to identify the wear plate workpiece, there is no need to move the large gantry frame body; only the camera 84 needs to be moved for rapid visual identification. This not only greatly shortens the visual identification time and improves production efficiency, but also allows the visual identification equipment 80 to flexibly adapt to blank docking tables 31 of different sizes.

[0056] In addition, the camera 84 is connected to the control unit via signal, enabling it to transmit captured image data to the control unit in real time, thereby guiding the first transfer robot 60 to accurately grasp the wear plate workpiece and ensure the accuracy of subsequent processing operations.

[0057] It should be noted that, in a preferred embodiment of this invention, the drive component 83 is a rodless cylinder and the camera 84 is a 3D camera.

[0058] It should be noted that, in this embodiment, the wear plate processing production line can be equipped with multiple blank docking stations 31 to receive wear plate workpieces supplied from AGV vehicles in parallel. The configuration of the vision recognition device 80 can be as follows: a single vision recognition device 80 can be set above multiple blank docking stations 31; an independent vision recognition device 80 can be set above each blank docking station 31 to achieve independent recognition of wear plate workpieces on each blank docking station 31; or a vision recognition device 80 can be set above only one specific blank docking station 31 as a global or polling recognition center.

[0059] When the vision recognition device 80 is only installed above a blank docking station 31, its workflow is as follows: The first batch of wear plate workpieces is transported to the blank docking station 31 equipped with the vision recognition device 80. The vision recognition device 80 identifies the wear plate workpieces, obtains their specific specifications and types, and sends the identification results to the control unit. The control unit records the processing requirements of the current wear plate processing production line or establishes a mapping relationship between materials and production tasks based on the identified wear plate workpiece type. In subsequent production, AGV vehicles can transport the same type of wear plate workpieces to other blank docking stations 31 that are not equipped with vision recognition devices 80, and the wear plate processing production line can process them according to the identified type information. If the wear plate processing production line needs to be changed to produce wear plates of different specifications, the new wear plate workpieces need to be transported to the blank docking table 31 equipped with vision recognition equipment 80 for re-identification. This structure can reduce the number of vision recognition equipment 80 and reduce equipment costs, while still ensuring that the wear plate processing production line can adapt to the processing of wear plates of multiple specifications and realize the orderly flow and precise processing of wear plate workpieces on the production line, thus achieving a balance between cost and efficiency.

[0060] In this embodiment, the wear-resistant board processing production line also includes a central control system. The machining center 20, the lettering equipment 50, the vision recognition equipment 80, the first transfer robot 60, and the second transfer robot 70 are respectively connected to the central control system via signals. The central control system includes control components. By setting up a central control system and connecting the machining center 20, the lettering equipment 50, the vision recognition equipment 80, the first transfer robot 60, and the second transfer robot 70 to the central control system via signals, the coordinated control and scheduling of the entire wear-resistant board processing production process is realized.

[0061] Specifically, the central control system can acquire the real-time status of each device and coordinate the operation of the machining center 20, the lettering machine 50, the vision recognition device 80, the first transfer robot 60, and the second transfer robot 70. For example, after the first transfer robot 60 places the wear plate workpiece to be lettered on the inter-process workpiece waiting table 40, the central control system controls the second transfer robot 70 to pick up the material and controls the lettering machine 50 to perform the operation; after the operation is completed, the second transfer robot 70 is then controlled to transfer the finished wear plate to the finished product docking table 32. This automated workflow shortens the waiting time between processes and improves overall production efficiency.

[0062] Secondly, the central control system can also guide the first transfer robot 60 to grasp the wear plate workpiece based on the specifications, type, position and posture information identified by the vision recognition device 80, and automatically call the corresponding processing program in the machining center 20. This avoids the tedious operation and potential errors of manually switching programs and selecting equipment, enabling the production line to flexibly meet the needs of multi-specification wear plate production, and realize unmanned intelligent operation of the entire wear plate processing production process from blank loading to finished product unloading.

[0063] like Figure 2 The machining center 20 includes a tooling base plate 21, a positioning mechanism 22, and a clamping mechanism 23. The positioning mechanism 22 and the clamping mechanism 23 are both set on the tooling base plate 21 to realize the positioning and clamping of the wear plate workpiece on the tooling base plate 21.

[0064] In this embodiment, both the positioning mechanism 22 and the clamping mechanism 23 are integrated on the tooling base plate 21. Working in conjunction with the first loading / unloading position of the first transfer robot 60, they can automatically complete the placement, positioning, and clamping of the wear plate workpiece. This structural design not only simplifies the operation process and reduces manual intervention, but also significantly improves clamping speed and repeatability, ensuring the consistency of the wear plate workpiece on the processing datum, thereby guaranteeing the processing accuracy and quality stability of the wear plate workpiece.

[0065] Specifically, after the first transfer robot 60 accurately places the wear plate workpiece onto the tooling base plate 21, the positioning mechanism 22 performs preliminary positioning of the wear plate workpiece according to preset parameters. Subsequently, the clamping mechanism 23 actuates to firmly clamp the wear plate workpiece. The automated loading, unloading, positioning, and clamping processes in this embodiment can effectively eliminate errors caused by manual alignment and manual clamping, improve production efficiency, significantly reduce the labor intensity and safety risks of operators, and enhance the adaptability of the wear plate processing production line to the processing of wear plates of different specifications.

[0066] like Figure 2As shown, the positioning mechanism 22 includes a positioning block 221, a side push plate 222, and a side push cylinder 223 arranged sequentially along the second transverse direction. The positioning block 221 and the side push cylinder 223 are both fixedly mounted on the tooling base plate 21. The side push plate 222 is movably mounted on the tooling base plate 21 along the second transverse direction. The side push plate 222 is drivenly connected to the side push cylinder 223.

[0067] Specifically, the positioning mechanism 22 can position wear plates of different specifications. Since there are more than a dozen specifications of wear plates with varying sizes, when the wear plate processing production line processes wear plates of different specifications, the positioning mechanism 22 needs to drive the side push plate 222 to move along the second transverse direction using the side push cylinder 223, according to the size of the wear plate workpiece. The side push cylinder 223 is controlled to extend or retract by a corresponding distance, thereby moving the side push plate 222 to the corresponding position. The side push plate 222 is in close contact with the side of the wear plate and cooperates with the fixedly installed positioning block 221 to position the wear plate workpiece from both sides in the second transverse direction. In this embodiment, the positioning mechanism 22 can adapt to the positioning requirements of wear plates of different widths, enabling the machining center 20 to be compatible with multiple specifications of wear plates without the need for manual replacement of positioning blocks or adjustment of tooling, thus improving the processing adaptability of the wear plate processing production line.

[0068] In addition, the positioning mechanism 22 has a compact layout and is easy to integrate. The positioning block 221, the side push plate 222 and the side push cylinder 223 are arranged in sequence along the second transverse direction and are all fixed on the tooling base plate 21. They occupy little space and are conducive to arranging multiple positioning stations on the limited tooling base plate 21 or coordinating with the clamping mechanism.

[0069] like Figure 2 As shown, the clamping mechanism 23 includes a first clamp 24 and a second clamp 25. The first clamp 24 includes a synchronous hydraulic cylinder 241 and two clamping plates 242. The synchronous hydraulic cylinder 241 is fixedly mounted on the tooling base plate 21. The two clamping plates 242 are symmetrically arranged on both sides of the positioning mechanism 22 in the first transverse direction. The synchronous hydraulic cylinder 241 is driven to connect with the clamping plates 242, and the synchronous hydraulic cylinder 241 drives the two clamping plates 242 to move closer or further away from each other. The second clamp 25 includes an upper pressure block 251 and a drive cylinder 252. The upper pressure block 251 is located above the clamping plate 242 in the vertical direction. The drive cylinder 252 is fixedly mounted on the tooling base plate 21 and is drivenly connected to the upper pressure block 251. The upper pressure block 251 has a pressing position and a clearance position. When the upper pressure block 251 is in the pressing position, the projection of the upper pressure block 251 on the tooling base plate 21 is located between the projections of the two clamping plates 242 on the tooling base plate 21. When the upper pressure block 251 is in the clearance position, the projection of the upper pressure block 251 on the tooling base plate 21 is located on the side of the projections of the two clamping plates 242 on the tooling base plate 21 in the horizontal direction.

[0070] Specifically, the first fixture 24 achieves bidirectional synchronous clamping of the wear plate workpiece in the first transverse direction. Two clamping plates 242 are symmetrically arranged on both sides of the positioning mechanism 22 in the first transverse direction. After the wear plate workpiece is positioned by the positioning mechanism 22, the synchronous hydraulic cylinder 241 drives the two symmetrically arranged clamping plates 242 to move closer together to clamp the wear plate workpiece. The clamping forces applied by the two clamping plates 242 to the wear plate workpiece are equal in magnitude and opposite in direction, which can prevent the wear plate workpiece from tilting, shifting, or rotating during processing due to uneven force. Especially in processes such as drilling and milling that generate large cutting forces, the lateral clamping force provided by the first fixture 24 can effectively fix the wear plate workpiece, ensuring the accuracy of the machining dimensions and surface quality.

[0071] Secondly, the upper pressure block 251 is located above the clamping plate 242. The driving cylinder 252 can drive the upper pressure block 251 to move vertically and rotate along the axial direction of the driving cylinder 252 to achieve clamping of the wear plate workpiece. The upper pressure block 251 has a clamping position and a clearance position. When the upper pressure block 251 is in the clamping position, the projection of the upper pressure block 251 on the tooling base plate 21 is located between the projections of the two clamping plates 242 on the tooling base plate 21, thereby vertically clamping the wear plate workpiece. When the upper pressure block 251 is in the avoidance position, the drive cylinder 252 drives the upper pressure block 251 to rotate. The projection of the upper pressure block 251 on the tooling base plate 21 is located on the side of the projection of the two clamping plates 242 on the tooling base plate 21 in the lateral direction. The upper pressure block 251 will not interfere with the loading and unloading of the first transfer robot 60, preventing the risk of interference between the first transfer robot 60 and the clamping mechanism 23, and improving the stability of the wear plate processing production line.

[0072] It should be noted that the upper pressure block 251 being located above the clamping plate 242 in the vertical direction includes two situations: when the upper pressure block 251 is in the pressing position, the upper pressure block 251 is directly above the clamping plate 242 in the vertical direction; when the upper pressure block 251 is in the clearance position, the upper pressure block 251 is diagonally above the clamping plate 242 in the vertical direction.

[0073] like Figure 2As shown, the upper pressure block 251 includes a pressure strip 2511, and the driving cylinder 252 includes a corner cylinder 2521. One end of the pressure strip 2511 is fixedly connected to the corner cylinder 2521, and the corner cylinder 2521 is rotatably mounted on the tooling base plate 21 around its vertical axis. The clamping mechanism 23 includes two positioning mechanisms 22 and two first clamps 24 arranged in a one-to-one correspondence. The two first clamps 24 are spaced apart in the first transverse direction, and the corner cylinder 2521 is located between the two first clamps 24 in the first transverse direction. When the upper pressure block 251 is in the pressing position, the extension direction of the pressure strip 2511 is parallel to the first transverse direction. The projections of the two ends of the pressure strip 2511 on the tooling base plate 21 are respectively located between the projections of the two clamping plates 242 of the corresponding first clamps 24 on the tooling base plate 21. When the upper pressure block 251 is in the clearance position, the projection of the pressure strip 2511 on the tooling base plate 21 is located in the transverse direction between the projections of the two first clamps 24 on the tooling base plate 21.

[0074] In this embodiment, the tooling base plate 21 of the machining center 20 is provided with two corresponding positioning mechanisms 22 and two first clamps 24, and the two first clamps 24 are arranged at intervals in the first transverse direction. The corner cylinder 2521 is located between the two first clamps 24 in the first transverse direction, realizing the dual-station clamping structure of the machining center 20. The corner cylinder 2521 is located between the two first clamps 24, and the pressure bar 2511 rotates around the vertical axis through the corner cylinder 2521, which can cover the working area of ​​the two stations. That is, when the pressure bar 2511 rotates to the clamping position, its two ends fall into the clamping plates 242 of the two first clamps 24 respectively, thereby vertically clamping the wear plate workpiece; when the pressure bar 2511 rotates to the avoidance position, its transverse projection is located between the two first clamps 24, and no longer blocks the space above either station. The above structure allows a second fixture 25 to be used for two stations of the machining center 20, saving space on the tooling base plate 21. When the first transfer robot 60 enters the machining center 20 and picks up the finished wear plate at the station, the next wear plate blank can be placed in another station. The two stations alternate to realize automated dual-station clamping of wear plates of different specifications.

[0075] It should be noted that the machining center 20 also includes a chip-prevention structure. During drilling, milling, and other machining processes in the machining center 20, a large amount of metal chips are generated. If these chips enter the positioning mechanism 22 or clamping mechanism 23, they will affect the positioning accuracy of the wear plate workpiece. Therefore, by setting up chip-prevention structures such as sealing grooves, scraper plates, or reasonable clearance fits, chips are effectively prevented from entering the positioning mechanism 22 or clamping mechanism 23, ensuring the positioning and clamping accuracy of the positioning mechanism 22 and clamping mechanism 23 during long-term operation.

[0076] like Figure 3As shown, the wear plate processing production line also includes an AGV vehicle and multiple guide frames 90. The multiple guide frames 90 are spaced apart in the first transverse direction. The gap between two adjacent guide frames 90 forms a placement space for placing the blank docking table 31 or the finished product docking table 32. The wear plate processing production line also includes an anti-collision mechanism, which is connected to the AGV vehicle via a signal.

[0077] Specifically, the wear plate processing production line also includes AGVs (Automated Guided Vehicles). These AGVs, acting as automated guided vehicles, autonomously transport a full load of wear plate workpieces from the intelligent warehouse to the blank docking station 31, and then transport the finished wear plates processed at the finished product docking station 32 back to the warehouse. Utilizing AGVs for automated transport replaces traditional manual forklift handling or manual trolley pushing, significantly reducing the labor intensity of workers, avoiding safety hazards during manual handling, and improving the production efficiency of the wear plate processing production line.

[0078] Furthermore, the guide frame 90 ensures the precise positioning and docking of the AGV with the blank docking station 31 or the finished product docking station 32. Multiple guide frames 90 are spaced apart along the first lateral direction, with the placement space between adjacent guide frames corresponding to the position of the blank docking station 31 or the finished product docking station 32. When the AGV enters the designated workstation, the guide frame 90 guides and limits the AGV's travel path, ensuring precise alignment between the AGV and the blank docking station 31 or the finished product docking station 32, thus avoiding subsequent process failures due to positional deviations or interference with other equipment on the wear plate processing production line.

[0079] In addition, the wear plate processing production line also includes an anti-collision mechanism, which consists of limit switches and anti-collision blocks. The anti-collision mechanism is connected to the AGV vehicle via signal. The AGV vehicle transfers a full load of wear plate blanks from the intelligent warehouse to the blank docking table 31, or the AGV vehicle transfers a full load of finished wear plate parts from the finished product docking table 32 to the intelligent warehouse. During this process, the guide frame 90 of the blank docking table 31 is positioned, the limit switches send a positioning signal, and the anti-collision blocks prevent the AGV vehicle from colliding with other components of the wear plate processing production line, thus improving the safety of the wear plate processing production line operation.

[0080] like Figure 1 and Figure 3 As shown, the wear plate processing production line also includes a protective device 110. The production line track 10, machining center 20, material docking station 30, inter-sequence workpiece waiting station 40, lettering equipment 50, first transfer robot 60, second transfer robot 70, and vision recognition equipment 80 are all housed within the protective device 110. The protective device 110 serves as a physical barrier, preventing operators from accidentally entering the wear plate processing production line or coming into contact with hazardous equipment, effectively avoiding mechanical injury accidents.

[0081] It should be noted that, in this embodiment, the protective device is a safety fence.

[0082] like Figure 1 As shown, the wear plate processing production line also includes a manual inspection slide 100, which is set at the second end of the production line track 10 in the first transverse direction.

[0083] Specifically, in the first transverse direction, the manual inspection slide 100 is positioned at the second end of the production line track 10 to prevent the inspection process from interfering with the operation of the second transfer robot 70 and the processing of the lettering equipment 50. The manual inspection slide 100 also includes a safety light curtain and an electromagnetic lock. When an operator needs to perform an inspection, the first transfer robot 60 grabs the finished wear plate and places it on the manual inspection slide 100. When the operator pulls out the slide 100, the safety light curtain is triggered, and the central control system sends a signal, causing the wear plate processing production line to automatically stop or enter a safe waiting state. The operator does not need to search for inspection points in the complex production line environment or manually turn off multiple equipment switches. After the inspection is completed, the central control system only releases the shutdown state and allows the wear plate processing production line to resume operation after the slide is fully pushed back and confirmed to be in place by the electromagnetic lock. The addition of the electromagnetic lock further ensures that the slide is locked in a non-inspection state, preventing accidental shutdown and also preventing the production line from being accidentally started when the slide is not locked, increasing the standardization and reliability of the operation.

[0084] By setting up a manual inspection slide 100, the inspection process is only triggered when the manual inspection slide 100 is pulled out, which triggers the automatic shutdown of the wear plate processing production line or puts it into a safe waiting state. Since the inspection is carried out intermittently, the wear plate processing production line can maintain automatic continuous operation most of the time, which can minimize the interference with the normal production process.

[0085] In this embodiment, the ends of the first transfer robot 60 and the second transfer robot 70 are provided with electromagnetic wrists, each electromagnetic wrist containing 4 electromagnets, and each electromagnet is independently controlled by a controller.

[0086] Specifically, the electromagnetic wrist has a power-off retention function, meaning that in the event of a sudden power outage or other abnormal situation on the production line, the electromagnetic wrist can still maintain the attraction to the wear plate workpiece, effectively preventing the wear plate workpiece from falling off during the transfer process and improving the operational stability of the wear plate processing production line.

[0087] Secondly, the use of an electromagnetic wrist as the robot's end effector allows for the gripping of 1-2 workpieces at a time, improving transfer efficiency. The electromagnetic adsorption method is compatible with wear plates of different shapes and sizes, eliminating the need to change to specialized mechanical clamps for different specifications, simplifying the changeover process and meeting the needs of multi-specification wear plate production. Simultaneously, the electromagnetic force of the electromagnet can be flexibly adjusted, avoiding damage to the wear plate workpiece surface caused by excessive clamping force, as is common with traditional mechanical grippers. Furthermore, electromagnetic adsorption is less affected by metal chips on the workpiece surface, effectively overcoming chip interference and preventing gripping failures or workpiece surface scratches caused by chip adsorption, ensuring the reliability of loading and unloading operations and workpiece quality in complex processing environments.

[0088] The following describes the abrasion plate processing flow of the abrasion plate processing production line of this application:

[0089] The AGV transports a fully loaded material frame of blanks from the intelligent warehouse to the blank docking station 31. During this process, the guide frame 90 guides and positions the AGV, and the limit switch sends a positioning signal. The drive unit 83 of the vision recognition device 80 drives the camera 84 to move above the wear plate workpiece. The camera 84 captures images and identifies the type, position, and posture of the wear plate workpiece, and controls the first transfer robot 60 to precisely grasp it through the control unit. The first transfer robot 60 moves along the production line track 10 to the designated machining center 20. The machining center 20 automatically opens its door, and the first transfer robot 60 sends the wear plate workpiece onto the dual-station fixture of the machining center 20. The positioning mechanism 22 positions the wear plate workpiece, and the first fixture 24 and the second fixture 25 automatically clamp the wear plate workpiece. The machining center 20 then begins processing the wear plate workpiece (drilling, chamfering, tenoning, etc.).

[0090] After processing, the machining center 20 automatically opens its door, and the first transfer robot 60 grabs the wear plate workpiece. Simultaneously, the next wear plate workpiece can be placed in another station, achieving dual-station alternation and enabling continuous loading and unloading of the wear plate processing production line. For workpieces requiring lettering, the first transfer robot 60 transports them to the inter-stage workpiece waiting platform 40 for temporary storage. The second transfer robot 70 grabs the wear plate workpiece from the inter-stage workpiece waiting platform 40 and sends it to the lettering fixture on the lettering equipment 50. A sensor switch on the lettering fixture detects the wear plate workpiece's arrival, and the slider descends to press the mark. After completion, the slider returns, and the second transfer robot 70 grabs the finished wear plate and sends it to the finished product docking platform 32. For workpieces not requiring lettering, the first transfer robot 60 directly sends the finished wear plate to the finished product docking platform 32, and the AGV transports the full frame of finished wear plates back to the intelligent warehouse. When random inspection is required, the operator pulls out the manual inspection slide. At this time, the safety light curtain automatically triggers the wear board processing production line to stop, picks up the part for inspection, and pushes back the manual inspection slide and locks the electromagnetic lock after completion, thus ending one wear board processing production cycle. Among them, the machining center 20, the lettering device 50, the vision recognition device 80, the first transfer robot 60, and the second transfer robot 70 are respectively connected to the central control system. Under the scheduling of the central control system, they cycle back and forth to continuously complete the automatic loading and unloading, processing, lettering, and transfer of wear boards.

[0091] This invention provides a wear plate processing production line consisting of a machining center 20, a material docking station 30, an inter-sequence workpiece waiting station 40, an AGV vehicle, a lettering device 50, a first transfer robot 60, a second transfer robot 70, a vision recognition device 80, a guide frame 90, a manual sampling slide 100, and a protective device 110. The entire line is centrally controlled by a production control system, achieving fully automated and intelligent production from material loading, processing, lettering, inspection, and unloading. The automatic operation of the wear plate processing production line effectively improves production efficiency, product quality, reduces operator workload, and minimizes the number of operators required. It is suitable for large-scale, mass production of railway freight cars, realizing a shift from discrete manual labor to continuous automation. Only one person is needed to operate the entire line, significantly improving efficiency, quality consistency, and safety. Furthermore, the wear plate processing production line provided by this invention can process a wide variety of wear plates, comprehensively covering various specifications, with high production capacity, good production consistency, and superior processing accuracy indicators.

Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing the invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this invention.
