DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 8 The present invention provides a double-sided edging system, comprising a machine tool body 1, a rotating fixed fixture assembly 2 is arranged on the machine tool body 1, and a lateral movement assembly is arranged on the left and right sides of the rotating fixed fixture assembly 2, a synchronous opening and closing control assembly 4 for controlling the opening and closing distance of the two lateral movement assemblies is arranged in the machine tool body 1, an edging assembly 5 is arranged on the lateral movement assembly, a synchronous height adjustment structure 6 for controlling the grinding height of the edging assemblies 5 on both sides is arranged on the machine tool body 1, and a visual detection assembly 7 for detecting the thickness and outer contour shape of a workpiece is arranged in the machine tool body 1; The following steps are also included: S1, the visual detection component 7 starts working, aims at the workpiece from different directions, and captures the visual information of the outer contour image of the workpiece; the analog image signal collected in real time is quickly converted into a digital signal, and transmitted to the image processing module connected to it through a high-speed data transmission line; S2, the visual detection component 7 focuses on the thickness section direction of the workpiece, captures and obtains an image reflecting the thickness characteristics of the workpiece, and the collected image data is also immediately transmitted to the image processing module; S3, the image processing module immediately transmits the deviation information to the control module; the control module quickly formulates an adjustment strategy based on the deviation details; the control module issues corresponding action instructions to start the synchronous opening and closing control component 4 and the synchronous height adjustment structure 6 to adjust the edge grinding size and height; S4. During the edge grinding process, the visual inspection component 7 continues to work according to the preset cycle, repeating the above steps of image acquisition, processing, analysis, feedback adjustment, and optimizing the edge grinding process parameters in real time until the outer contour shape and thickness of the workpiece meet the preset qualified standards, completing the entire visual inspection and edge grinding process; The device can process a symmetrical workpiece 100 which is symmetrical front to back and left to right.

[0018] The workpiece is placed on the rotating base 203 of the rotating fixed fixture assembly 2, and the push rod motor 205 on the upper bracket 204 is started to drive the rotating clamping part 206 to move downward, and cooperate with the rotating base 203 to clamp the workpiece. Since the rotating clamping part 206 and the rotating base 203 are provided with an anti-slip layer on the surface, the workpiece can be effectively prevented from sliding during the subsequent processing. At the same time, the active motor 202 can drive the rotating base 203 to rotate, so that the workpiece can be edged at different angles.

[0019] The visual inspection component 7 starts working, and the multiple first lenses 701 arranged on the upper bracket 204 take pictures of the outer contour of the workpiece, and the second lens 702 located on the workbench 201 detects the thickness of the workpiece. These lenses transmit the collected image data to the image processing module connected to them, and the image processing module analyzes and processes the image, extracts key parameter information such as the outer contour shape and thickness of the workpiece, and sends this information to the control module.

[0020] Adjustment of the opening and closing distance: The control module sends instructions to the forward and reverse motor 4051 according to the workpiece outer contour information fed back by the image processing module. The forward and reverse motor 4051 is started, and the driving gear 4052 at its output end drives the driven gear 4053 on the outer wall of the circumference of the rotating ring body 401 to rotate, so that the rotating ring body 401 rotates in the annular mounting seat. The eccentric shaft 402 on the lower end face of the rotating ring body 401 rotates accordingly, and the driving connecting rod 404 pushes the horizontal slider 302 to slide in the horizontal guide groove 301, thereby adjusting the opening and closing distance of the lateral moving components on both sides, so that the edge grinding component 5 can fit the outer contour of the workpiece.

[0021] The control module sends a command to the height adjustment cylinder 6082 based on the workpiece thickness information. The height adjustment cylinder 6082 is actuated, and drives the vertical guide shaft 602 to move up and down in the vertical guide hole 601 through the connecting rod 6083. The driving rod 603 at the upper end of the vertical guide shaft 602 rises and falls accordingly, and the height adjustment sleeve hole 604 at the inner end of the driving rod 603 drives the synchronous sleeve 606 to move up and down through the limit ring 609. Since the synchronous guide groove 607 on the inner wall of the synchronous sleeve 606 cooperates with the synchronous guide bar 605 at the output end of the drive motor 501, the grinding wheel 502 can adjust the height up and down and can also cooperate with the drive motor 501 for rotational grinding; so as to cover the different thickness positions of the grinding workpiece.

[0022] After the position of the edge grinding component 5 is adjusted, the drive motor 501 is started to drive the grinding wheel 502 to rotate and perform edge grinding on both sides of the workpiece. During the processing, the rotating fixed fixture component 2 can drive the workpiece to rotate as needed, so that different parts of the workpiece can be evenly edged. At the same time, the visual detection component 7 continues to work and monitors the processing of the workpiece in real time. If a deviation is found, the control module will adjust the position and height of the edge grinding component 5 in time to ensure the processing accuracy.

[0023] Workpiece clamping: Place the workpiece to be processed on the rotating fixed fixture assembly 2, and clamp it by rotating the clamping part 206 and the rotating base 203 to ensure that the workpiece is fixed firmly. At this time, prepare to start the visual inspection process.

[0024] Outer contour image acquisition: Multiple first lenses 701 installed on the upper bracket 204 are started synchronously, aiming at the workpiece from different directions, and using their high-resolution imaging capabilities to capture the outer contour image of the workpiece. These lenses are carefully arranged to cover all sides of the workpiece, ensuring that comprehensive and clear outer contour visual information is obtained.

[0025] The first lens 701 quickly converts the analog image signal collected in real time into a digital signal, and transmits it to the image processing module connected to it through a high-speed data transmission line. Thickness image acquisition: The second lens 702 located on the workbench 201 is vertically aimed downward at the workpiece, focusing on the thickness section direction of the workpiece, and capturing an image reflecting the thickness characteristics of the workpiece. The lens has precise focusing and depth measurement functions to ensure the accuracy of the collected thickness image.

[0026] Likewise, the image data captured by the second lens 702 is also immediately transmitted to the image processing module.

[0027] Image processing and analysis: After receiving the image data from the first lens 701 and the second lens 702, the image processing module uses a built-in complex algorithm to process it. For the outer contour image, the contour line is identified and extracted, and key geometric features such as edge length, angle, curvature, etc. are calculated; for the thickness image, the thickness value is accurately measured and quantified.

[0028] Next, the actual characteristic parameters of the workpiece obtained after processing are compared in detail with the standard workpiece parameters pre-stored in the system to determine whether there are deviations in the outer contour shape and thickness of the workpiece, as well as the specific value and direction of the deviation.

[0029] Deviation feedback and adjustment decision: Once a deviation is found in the workpiece, the image processing module immediately transmits the deviation information to the control module. The control module quickly formulates an adjustment strategy based on the deviation details.

[0030] If the outer contour deviation requires adjustment of the relative positions of the edge grinding components 5 on both sides, the control module sends precise drive instructions to the forward and reverse motors 4051; if the thickness deviation requires changing the grinding height, the control module issues corresponding action instructions to the height adjustment cylinder 6082. Adjustment of edge grinding components: After receiving the instructions from the control module, the forward and reverse motors 4051 start, driving the active gear 4052 to drive the passive gear 4053 to rotate, thereby rotating the rotating ring body 401. The eccentric shaft 402 at the lower end of the rotating ring body 401 drives the transverse slider 302 to slide in the transverse guide groove 301 through the driving connecting rod 404, so as to adjust the opening and closing distance of the transverse moving components on both sides to adapt to the outer contour finishing of the workpiece.

[0031] At the same time, the height adjustment cylinder 6082 works to push the connecting rod 6083 to move the vertical guide shaft 602 up and down in the vertical guide hole 601. The vertical guide shaft 602 drives the driving rod 603 to move up and down, and with the cooperation of the synchronous guide bar 605 and the synchronous sleeve 606, the grinding wheel 502 of the edge grinding assembly 5 is driven to adjust to a precise grinding height to meet the workpiece thickness correction requirements.

[0032] Cyclic detection and correction: During the edge grinding process, the visual detection component 7 continues to work according to a preset cycle, repeating the above steps of image acquisition, processing, analysis, feedback adjustment.

[0033] The workpiece status is continuously monitored and the edge grinding process parameters are optimized in real time until the outer contour shape and thickness of the workpiece meet the preset qualified standards, completing the entire visual inspection and edge grinding process.
