Description

Technical Field

[0001] This invention relates to the field of industrial automation technology, and in particular to a processing equipment and processing method. Background Technology

[0002] In the field of machining and manufacturing, long tubular workpieces with disc-like structures require surface spraying or galvanizing to improve oxidation resistance and prevent rusting. However, galvanizing easily produces surface defects such as zinc dross and drips. These defects not only affect the product's appearance but also the assembly accuracy and performance of the workpiece. Therefore, these surface defects must be removed during subsequent processing. Currently, zinc dross removal for long tubular workpieces with discs is often done manually or with semi-automatic equipment. Furthermore, these workpieces are prone to slight deformation during previous processing or heat treatment, causing the disc to no longer be perfectly perpendicular to the tube, or the tube itself to be bent, resulting in potential concentricity deviations. These problems affect the final product quality. Currently, the perpendicularity correction of the disc and the straightness correction of the tube are often performed as independent, offline processes.

[0003] The shortcomings of existing technologies lie in the fact that manual grinding methods suffer from high labor intensity, low production efficiency, unstable grinding quality, and are greatly affected by the operator's skill level. Existing semi-automatic equipment is typically single-function and cannot complete all processing tasks within a single system, requiring workpieces to be transferred between multiple independent workstations, increasing production cycle time and logistics costs. Furthermore, the need for additional equipment and operators for disc perpendicularity and straightness correction necessitates multiple clamping operations, introducing new error risks and hindering overall production efficiency, resulting in discrete processes and excessively long processing cycles. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a processing equipment and processing method that can integrate automated grinding, online appearance inspection and geometric accuracy correction of galvanized long tube workpieces into one, effectively improving processing efficiency and realizing efficient automated production.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention. Example 1

[0028] Reference Figures 1 to 7 As shown, the present invention discloses a processing equipment for grinding, visual inspection and calibration of the workpiece 1 to be processed.

[0029] Specifically, the workpiece 1 to be processed includes a long tube 10 and disks 11 spaced apart from the long tube. There are multiple disks 11, which are spaced apart along the length of the long tube 10. Theoretically, the disks 11 are sleeved on the long tube 10, and the thickness direction of the disks 11 is consistent with the axial direction of the long tube 10. It can also be understood that the disks 11 and the long tube 10 are coaxially connected.

[0030] The processing equipment includes a worktable, which includes a first platform 21 and a second platform 22 arranged vertically; the first platform 21 and the second platform 22 are arranged horizontally.

[0031] The processing equipment also includes a gripping unit 3, which is used to grip and transfer the workpiece 1 to be processed. The gripping unit 3 is adjacent to the worktable. The processing equipment also includes a grinding unit 4, which is disposed on the first platform 21. The grinding unit includes a first support frame 40, a first transfer component 41, a first drive mechanism 42, a grinding station 43, and at least one grinding component 44. The first support frame 40 is disposed on the first platform 21 near the gripping unit 3. There are at least two first support frames 40, which are arranged opposite each other along a first direction. The first support frame 40 is provided with a groove that is adapted to the workpiece 1 to be processed. The workpiece 1 to be processed is placed on the first support frame 40 along the first direction. The first support frame 40 is used to temporarily store the workpiece 1 to be processed.

[0032] The first transfer assembly 41 is used to transfer the workpiece 1 to be processed from the first support frame 40 to a position where it docks with the first drive mechanism 42. The workpiece 1 rotates at high speed under the drive of the first drive mechanism 42. At least one of the grinding assemblies 44 approaches the workpiece 1 and grinds the disc 11 of the workpiece. Specifically, the grinding head of the grinding assembly 44 rises and falls, while the disc 11 rotates and indexes to complete the grinding of zinc slag and zinc flow treatment on the entire surface of the disc.

[0033] In detail, the first transfer component 41 includes a first linear module, a transfer cylinder 410, and a material support bracket 411. The first linear module is disposed on the first platform 21 along the second direction, and the transfer cylinder 410 is installed on the movable end of the first linear module. The transfer cylinder 410 lifts the material support bracket 411, thereby lifting the workpiece 1 to be processed and moving it towards the grinding station 43. After lifting and adjustment, the workpiece is accurately delivered to the grinding station 43. The first drive mechanism 42 is disposed at one end of the grinding station along the first direction.

[0034] It should be noted that the second direction is perpendicular to the first direction.

[0035] The grinding station 43 includes at least two rolling support assemblies arranged opposite each other along a first direction; each rolling support assembly includes a support block and a roller assembly, the roller assembly is mounted on the top of the support block, and the roller assembly makes rolling contact with the workpiece 1 to be processed.

[0036] After polishing is completed, the workpiece 1 to be processed is lifted again by the first transfer component 41, moved out of the polishing station 43, and transported to the next process.

[0037] The processing equipment also includes a detection unit, which includes a buffer component 45 disposed on the second platform 22. The first platform 21 is provided with a transmission port 210 and a first guide structure 211. The first guide structure 211 is connected to the buffer component 45. The workpiece 1 to be processed after polishing is transmitted to the buffer component 45 through the first guide structure 211 for appearance inspection in the buffer component 45.

[0038] In this embodiment, an operator is assigned to this workstation to perform a visual inspection of the workpiece 1 to be processed, focusing on whether the polishing quality on each disc 11 meets the standards. The detection unit is also equipped with a confirmation button. After the operator checks and finds no errors, he presses the confirmation button, and the buffer component 45 rotates clockwise one workstation to send the workpiece 1 to be processed to the next workstation for the next process.

[0039] The processing equipment also includes a calibration unit, which is located on the second platform 22. The calibration unit includes a disk calibration component 51 and a concentricity calibration component 52.

[0040] Specifically, the disc calibration assembly 51 can perform disc calibration (alignment) on the workpiece 1 to be processed, so that the radial direction of the disc 11 is perpendicular to the axial direction of the long tube 10. The disc calibration assembly 51 includes a positioning mechanism 510 and a first pushing mechanism 511. The workpiece 1 to be processed can be initially positioned on the positioning mechanism 510. The positioning mechanism 510 can position the disc 11 and the long tube 10 respectively, so that the disc 11 and the long tube 10 meet the processing requirements. The first pushing mechanism 511 applies a pushing force along the axial direction (first direction) of the workpiece 1 to push the workpiece 1, thereby ensuring that the perpendicularity of the disc 11 and the long tube 10 meets the processing requirements and correcting the assembly angle of the disc 11.

[0041] The concentricity calibration component 52 includes a clamping detection mechanism 520 and a second pushing mechanism 521. The clamping detection mechanism 520 clamps the ends of the long tube 10 respectively. The two ends of the long tube 10 rotate under the drive of the clamping detection mechanism 520 to perform concentricity detection. The control unit judges the degree of bending of the workpiece 1 tube body by real-time feedback (such as runout) during rotation, and controls the second pushing mechanism 521 to straighten the bent tube body in order to calibrate the concentricity of the workpiece 1.

[0042] Finally, the workpieces that have completed the above processing are transferred again through the gripping unit 3 and placed in the finished product area or other designated locations.

[0043] It should be noted that the processing equipment also includes a control unit, which is used to receive signal feedback from the system and output control signals to the gripping unit 3, the grinding unit 4, the detection unit and the calibration unit in a timely manner.

The grinding unit and calibration unit are installed on the worktable. The gripping unit feeds the workpiece to the grinding unit for grinding. After grinding, the workpiece flows into the calibration unit for disc calibration and concentricity calibration. The calibrated material is then discharged through the gripping unit. This invention meets the automation and flexibility requirements of the grinding process, adapts to different products, and integrates key processes such as grinding, inspection, and calibration, improving production cycle time, meeting high-efficiency production requirements, and providing real-time product quality feedback for timely adjustments to preceding processes, avoiding batch production of defective products. The entire process can be completed within a specified time (≤35 seconds). Dual quality inspection of the workpiece is achieved through manual re-inspection (appearance inspection) and automated calibration, thus eliminating the need for separate inspection equipment and manpower, reducing production costs.

When the guide plate 451 rotates with the rotating shaft 450, the workpiece 1 slides out from the receiving groove to the next process. Preferably, three receiving grooves are evenly spaced on the guide plate 451.

[0052] Specifically, when the workpiece 1 is buffered in the receiving tank, the operator can inspect the appearance of the workpiece 1 to confirm the removal of zinc dross.

Step S3: Perform disk calibration on the workpiece 1 that enters the calibration unit. After positioning the workpiece 1, apply a pushing force to one end of the workpiece 1 so that the axial direction of the disk 11 is consistent with the axial direction of the workpiece 1, thereby correcting the assembly angle of the disk 11. After completing the disk calibration, the concentricity calibration of the workpiece 1 is performed, the rotation of the workpiece 1 is controlled, and the degree of bending of the workpiece 1 is judged by the real-time feedback during rotation. Determine whether the degree of bending of the workpiece 1 meets the preset specified range. If the degree of bending of the workpiece 1 is within the specified range, then cut the workpiece 1. When the bending degree of the workpiece 1 exceeds the specified range, a force is applied to the workpiece 1. The direction of the force is perpendicular to the axial direction of the workpiece, thereby straightening the workpiece 1 until the concentricity test result of the workpiece 1 meets the requirements; thereby achieving the purpose of adjusting the concentricity of the workpiece 1 and making the concentricity of the workpiece 1 consistent. Step S4: The workpiece 1 to be processed, after completing the concentricity calibration, is unloaded and transferred to the designated position by the gripping unit 3.

[0068] Therefore, it can be seen that the processing method of the present invention can achieve efficient and flexible grinding of the workpiece through the cooperation of multiple workstations, and has a transfer system to realize the ingenious transfer of the workpiece. It also has a manual appearance inspection step, which, together with the subsequent disc calibration and concentricity calibration steps, ensures that the geometric accuracy of the workpiece meets the requirements. The overall process is closely connected and the cycle is clear, which effectively improves the processing efficiency.
