In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0052] Combination Figures 1 to 10 As shown, according to a specific embodiment of the present invention, an automated processing system for a differential case is provided.

[0053] Specifically, Figure 1 As shown, the automated processing system for the differential case includes: a blank feeding device 100, the blank feeding device 100 has a storage station 3, and the blank feeding device 100 is used to transfer the workpiece to be processed to the storage station 3; a manipulator 200, the manipulator 200 is arranged adjacent to the blank feeding device 100; a processing device 300, the processing device 300 is arranged adjacent to the blank feeding device 100 and the manipulator 200; a measuring device 400, the measuring device 400 is arranged adjacent to the manipulator 200 and the processing device 300, and the measuring device 400 is communicatively connected with the processing device 300; and The feeding device 500 and the unloading device 500 are arranged adjacent to the manipulator 200; wherein the manipulator 200 is used to clamp the workpiece to be processed on the storage station 3 on the processing device 300, so that the processing device 300 processes the workpiece to be processed to obtain a finished workpiece, and the manipulator 200 is also used to clamp the finished workpiece on the measuring device 400, so that the measuring device 400 measures the size information of the finished workpiece, and detects whether the finished workpiece is qualified to obtain a qualified workpiece and an unqualified workpiece, and the manipulator 200 is used to respectively arrange the qualified workpiece and the unqualified workpiece on the unloading device 500.

[0054] In this embodiment, the system automatically loads and unloads materials through the robot 200 and automatically measures using the measuring device 400, which reduces manual intervention and can improve processing speed and production efficiency. The measuring device 400 is communicated with the processing device 300 and can detect the size information of the finished workpiece in real time, and transmit the measurement data to the processing device 300 in real time. The processing device 300 can perform data analysis and compensatory processing, thereby ensuring the accuracy of the workpiece processing size, effectively reducing the scrap rate caused by dimensional deviation, and improving product quality.

[0055] like Figure 2 As shown, the processing device includes: a frame; a loading component 301, the loading component 301 is connected to the frame, and the manipulator 200 is used to clamp the workpiece to be processed on the storage station 3 on the loading component 301; a unloading component 302, the loading component 301 and the unloading component 302 are arranged adjacent to each other, and the unloading component 302 is connected to the frame; a spindle component, the spindle component includes a first machine tool spindle 12 and a second machine tool spindle 13, and the first machine tool spindle 12 and the second machine tool spindle 13 are movably connected to the frame; a processing tool, the processing tool is arranged on a side of the frame close to the spindle component; wherein, the first machine tool spindle 12 has a first clamping state for clamping the workpiece to be processed, so that the processing tool can perform a primary processing on the workpiece to be processed to obtain a workpiece to be processed twice, and the second machine tool spindle 13 has a second clamping state for clamping the workpiece to be processed twice, so that the processing tool can perform a secondary processing on the workpiece to be processed twice to obtain a finished workpiece.

[0056] Through the setting of the first machine tool spindle and the second machine tool spindle, multi-process processing of the workpiece can be realized without manual or additional manipulators for the transfer between processes, which effectively improves the continuity and efficiency of the processing process. After completing the first processing on the first machine tool spindle, the workpiece is automatically transferred to the second machine tool spindle by the manipulator for secondary processing, which helps to improve the processing accuracy of the final product and reduce the positioning error caused by the transfer of the workpiece. The primary processing and the secondary processing can be carried out continuously in the same processing device, avoiding the time and energy of transferring the workpiece between different devices, greatly shortening the overall processing cycle and improving production efficiency.

[0057] Furthermore, the processing device also includes: a positioning and measuring component, at least part of the positioning and measuring component is located on the loading component 301, and another part of the positioning and measuring component is located on the spindle component, and at least part of the positioning and measuring component is used to collect angular position information of the workpiece to be processed; a control component, the positioning and measuring component is electrically connected to the control component, and the control component generates a first control instruction based on the angular position information, and the first control instruction is used to control the second machine tool spindle 13 to perform positioning and clamping compensation on the workpiece to be processed.

[0058] Specifically, the control component generates a first control instruction based on the angular position information, and this instruction is used for the second machine tool spindle to position and clamp the workpiece for compensation. The intelligent compensation mechanism can automatically adjust the angular position of the workpiece, eliminate the initial position deviation, and enable the machining tool to perform machining at the precise position of the workpiece, thereby ensuring the consistency and accuracy of the machining dimensions. Through automatic compensation, the machining error caused by the initial position deviation of the workpiece can be reduced, the scrap rate can be reduced, the utilization rate of materials can be improved, and production costs can be saved.

[0059] like Figure 4 As shown, the processing device also includes: an internal probe 31 of the machine tool, which is retractably arranged on the frame, and is arranged close to the first machine tool spindle 12. The internal probe 31 of the machine tool is used to measure the size information of the workpiece to be processed secondary clamped by the first machine tool spindle 12. The internal probe 31 of the machine tool is electrically connected to the control component, and the control component generates the processing allowance information based on the size information. The control component generates the processing strategy based on the processing allowance information, wherein the processing strategy is used to control the processing tool to perform rough processing and fine processing on the workpiece to be processed secondary.

[0060] The probe inside the machine tool can measure the dimensions of the workpiece to be processed again on the first machine tool spindle in real time, which enables the processing device to obtain the machining allowance information of the workpiece in real time and provide accurate data for subsequent processing. The control component generates a processing strategy based on the measurement results and can dynamically adjust the path and parameters of the machining tool to ensure machining accuracy. Based on the machining allowance information, the control component can intelligently determine whether the workpiece needs rough machining or fine machining. This intelligent selection of machining strategies avoids unnecessary machining steps and saves tools and machining time.

[0061] Specifically, when the machining allowance exceeds the process limit, the machine tool automatically adopts the process plan of rough machining first and then fine machining. When the machining allowance is less than the process limit, the machine tool automatically adopts the process plan of fine machining.

[0063] Furthermore, the processing device also includes: a workpiece flipping assembly 19, which is arranged between the loading assembly 301 and the unloading assembly 302, and the workpiece flipping assembly 19 is used to flip the workpiece to be processed again after completing the first processing; wherein, the first machine tool spindle 12 has a first clamping state in which it moves to the loading assembly 301 and clamps the workpiece to be processed, and the first machine tool spindle 12 has a first release state in which it moves to the workpiece flipping assembly 19 and releases the workpiece to be processed again; the second machine tool spindle 13 has a second clamping state in which it moves to the workpiece flipping assembly 19 and clamps the flipped workpiece to be processed again, and the second machine tool spindle 13 has a second release state in which it moves to the unloading assembly 302 and releases the finished workpiece.

[0064] Through the workpiece flipping assembly, the processing device can automatically flip the workpiece, so that the first machine tool spindle and the second machine tool spindle can respectively process two different surfaces of the workpiece without human intervention, which significantly improves the continuity and efficiency of processing.

By further positioning the workpiece at the spindle grabbing position 18, the displacement of the workpiece during the transmission process can be minimized, thereby reducing the processing error and improving the processing accuracy and yield of the parts. The coordinated use of the manipulator 200 and the machine tool feed channel 21 makes the workpiece loading process almost without manual intervention, reduces the dependence on the operator's skills, and improves the reliability of the processing process.

[0067] Furthermore, the unloading component 302 includes: a machine tool unloading channel 22, on which a machine tool unloading position 20 and a finished product unloading position 23 are provided.

The machine tool unloading channel 22 is used to transfer the finished workpiece to the finished product unloading position 23.

[0068] The automated unloading process reduces the need for operators and labor costs, while also reducing production interruptions caused by manual unloading errors and improving production continuity and efficiency.

[0069] like Figure 3As shown, a measuring station 17 is also provided on the material channel 21 of the machine tool.

[0070] The visual sensor can accurately collect the angular position information of the workpiece to be processed. The positioning measurement component also includes a second distance sensor 14. The second distance sensor 14 and the first distance sensor 15 are used to detect the distance between the clamping jaws of the first machine tool spindle 12 and the workpiece to be processed in real time to determine whether the clamping jaws are reliably clamped, ensure the precise alignment of the workpiece in the subsequent processing process, and reduce the processing error caused by angular deviation. The data collected by the visual sensor and the distance sensor can be directly transmitted to the control component. The control component intelligently generates control instructions based on this information to achieve accurate grasping and positioning of the workpiece, as well as precise control of subsequent processing, thereby improving the intelligent level of processing.

[0072] Real-time dimension detection and correction can effectively reduce waste caused by dimension deviation, improve yield rate and reduce production costs.

[0073] Specifically, the steps for the automated processing system for the differential case to process the measurement data of the measuring machine are as follows:

[0074] Step S1: Determination of the standard size of the workpiece: The machine tool PLC (i.e., the control component) determines whether the feedback data is qualified based on the upper and lower limits of the standard size of the workpiece.

[0075] Step S2: Deviation judgment and calculation: Compare and verify the measurement results, compare the measurement results with the upper limit value of the workpiece, if the comparison value is greater than the upper limit value, jump to alarm, if it is less than, continue to compare with the lower limit value of the workpiece, if it is less than the lower limit value, jump to alarm, if it is greater than the lower limit value, it means the workpiece is qualified, and then calculate the measurement result with the center line value of the workpiece to get the correction value.

[0076] Step S3: multiply the correction value by the coefficient: multiply the correction value calculated inside the PLC by the empirical value coefficient and store it in the PLC internal variable.

[0077] Step S4: Internal variable conversion: Convert PLC internal variables into NC system internal variables through FC21 function block.

[0078] Step S5: Tool compensation: The tool compensation data is generated by calculating the internal variables of the NC system and the relevant tool compensation values.
