Description

Technical Field

[0001] This application relates to the technical field of machining, and in particular to a grinding equipment and process for a fully automatic marine lock after casting. Background Technology

[0002] Complex castings such as marine automatic locks often require the treatment of multiple types of features during the grinding and cleaning stage. For example, it is necessary not only to remove large gating gates on the surface, but also to trim burrs and flash on complex curved surfaces such as internal cavities and holes. These different grinding tasks place different demands on the characteristics of the grinding tools: handling large allowances usually requires rigid disc grinding wheels with high torque, while handling complex cavities requires small, flexible finger-shaped or ball-head grinding tools.

[0003] In the early stages of automated grinding technology development and in existing common solutions, a layout was typically adopted to distribute different processes across multiple specialized machines to meet these diverse grinding needs. For example, a high-powered disc grinding head on one specialized machine was used for rough grinding of the risers and gates, and then the semi-finished workpiece was transferred to another machine equipped with a multi-axis robotic arm and a fine grinding head for fine grinding of internal cavities and complex contours. After completing the first process, the workpiece needed to be unloaded from the fixture and re-clamped onto the fixture of the second machine. The two clamping processes inevitably resulted in positioning deviations, causing the grinding program written for the second machine based on theoretical coordinates to fail to accurately match the actual position of the workpiece. This severely affected the quality of the fine grinding process and could even lead to the workpiece being scrapped due to grinding positional errors.

[0004] Secondly, the transfer, hoisting, repositioning and clamping of workpieces between multiple machines takes up a lot of non-processing time, which limits the entire production cycle to the speed of logistics transfer rather than the pure grinding efficiency, making it impossible to achieve continuous and smooth production. Summary of the Invention

[0005] In order to reduce machining errors, shorten the waiting time between different machining processes, and achieve a compact machining process, this application provides a grinding equipment and process for fully automatic marine lock casting.

[0006] On the one hand, this application provides a fully automatic grinding equipment for marine locks after casting, which adopts the following technical solution: A fully automatic marine lock grinding machine after casting includes: Equipment base, wherein the equipment base is provided with: A clamping mechanism used to clamp workpieces; The transfer mechanism is used to drive the workpiece and the clamping mechanism to move; A grinding mechanism includes a grinding assembly. The grinding assembly includes a grinding support, a first grinding device and a second grinding device disposed on the grinding support. The first grinding device includes a grinding wheel, and the second grinding device includes a grinding head. The second grinding device is rotatably disposed on the first grinding device, and the rotation axis of the second grinding device is collinear with the axis of the grinding wheel. A tilting assembly is provided on the grinding support for driving the second grinding device to rotate.

[0007] By adopting the above technical solution, during operation, the clamping mechanism can clamp and fix the workpiece, and the transfer mechanism drives the clamping mechanism and the workpiece to move together, sending the part of the workpiece to be processed to the grinding mechanism. In the grinding mechanism, the grinding wheel of the first grinding device can grind large areas such as the outer surface of the workpiece. When it is necessary to process the inner cavity or a specific angle, the flipping component drives the second grinding device to rotate, moving the second grinding device to the grinding station. The transfer mechanism drives the workpiece to move relative to the grinding head along a specific trajectory to complete fine grinding. By combining the clamping mechanism, the transfer mechanism, and the grinding mechanism that integrates the first and second grinding devices, multiple types of grinding operations can be completed in a single clamping of the workpiece. This fundamentally eliminates the positioning errors caused by transferring and repeatedly clamping between multiple machines, significantly improving processing accuracy and product consistency.

[0008] Optionally, the transfer mechanism includes an execution end, the execution end is connected to a movable seat, and the clamping mechanism is disposed on the movable seat; The clamping mechanism includes a clamping assembly, which includes a clamping rod and a lifting source. The clamping rod is positioned directly above the support platform, and the lifting source is used to drive the clamping rod to move up and down.

[0009] By adopting the above technical solution, the transfer mechanism is connected to the movable seat, providing the clamping mechanism with flexible movement capabilities of multiple degrees of freedom, ensuring that the workpiece can accurately reach any position that needs grinding. The combination of the support platform and the upper clamping rod constitutes a stable and reliable clamping solution, suitable for casting workpieces, which can effectively prevent workpiece displacement or vibration during grinding, further ensuring grinding accuracy and safety.

[0010] Optionally, it also includes a feeding mechanism, which is located on one side of the support platform and includes a support base, a rotation source, and a rotary worktable; The rotary worktable is rotatably mounted on the support base. Both ends of the rotary worktable are provided with mating slots. One end of each mating slot is provided with a discharge port. Each mating slot is fitted with a positioning fixture, and the positioning fixture is provided with a positioning groove adapted to the shape of the workpiece.

[0011] By adopting the above technical solution, the operator loads the workpiece into the positioning fixture at the external workstation of the equipment. After startup, the rotary source drives the rotary table to rotate 180 degrees, sending the clamped workpiece to the clamping mechanism, where it is fixed and processed directly above the support platform. Simultaneously, the workstation where the processed workpiece has been moved out is available for the operator to unload and reload, preparing for the next cycle. This achieves continuous and automated processing, significantly improving production efficiency.

[0012] Optionally, the grinding mechanism further includes a moving source for driving the grinding support to rotate, and the rotation axis of the grinding support is perpendicular to the rotation axis of the grinding wheel. The support platform is provided with a positioning rod, and the bottom of the positioning fixture is provided with a insertion groove for the positioning rod to be inserted and engaged. The movable seat is also equipped with a power source, which is used to drive the support platform to rotate.

[0013] By adopting the above technical solution, the rotation of the grinding support occurs simultaneously or alternately with the workpiece movement driven by the transfer mechanism, achieving dual motion capabilities for both workpiece movement and the grinding mechanism. The positioning pin on the support platform engages with the positioning fixture, enabling a detachable connection between the support platform and the positioning fixture. When the power source drives the support platform to rotate, it can cause the workpiece on the positioning fixture to rotate together, changing the relative position between the workpiece and the grinding mechanism. This expands the processing range of the equipment, optimizing the grinding path and angle through the relative motion of the workpiece and tool, thereby adapting to more complex workpiece geometries and improving processing quality and efficiency.

[0014] Optionally, the first grinding device further includes a grinding machine body and a driving component disposed on the grinding machine body, wherein the grinding wheel is disposed at one end of the grinding machine body, and the driving component is used to drive the grinding wheel to rotate; The flipping assembly includes a rotating bracket and a flipping source. The rotating bracket is sleeved on the grinding machine body and fixed on the second grinding device. The rotating bracket is sleeved outside the grinding machine body and rotatably connected to the grinding machine body. The flipping source is used to drive the rotating bracket to rotate.

[0015] By adopting the above technical solution, when the first grinding device is working, the drive component on the grinding machine body drives the grinding wheel to rotate at high speed. When the second grinding device needs to be activated, the rotating bracket is driven by the flip source, thereby causing the second grinding device, which is mounted on the grinding machine body, to rotate around the axis of the grinding wheel, adjusting the grinding head to the optimal working angle. Subsequently, the grinding head of the second grinding device starts to process the workpiece, ensuring the precision of grinding complex features such as the internal cavity of the workpiece.

[0016] Optionally, the clamping mechanism further includes a lifting guide assembly, which includes a vertical slide rail and a mounting slide perpendicular to the vertical slide rail. The mounting slide is slidably mounted on the vertical slide rail. One end of the clamping rod is connected to the mounting slide, and the lifting source is used to drive the mounting slide to lift.

[0017] By adopting the above technical solution, the lifting source drives the mounting slide to perform precise linear lifting and lowering movements along the vertical slide rail. The cooperation between the vertical slide rail and the mounting slide ensures that the clamping rod maintains vertical movement throughout the lifting process, preventing swaying. This results in more even and reliable force distribution on the workpiece, further reducing processing errors caused by clamping deviations, and also improving the stability and lifespan of the equipment.

[0018] Optionally, it also includes a device housing, which is fitted over the device base, and the device housing is provided with a protective door and a control module; The equipment housing is provided with a material inlet, and the feeding mechanism is located at the material inlet; A gate plate is fixed on the rotating worktable, and two matching slots are located on both sides of the gate plate. The gate plate is used to close the feed inlet.

[0019] By adopting the above technical solution, the protective door is closed during equipment operation, and all grinding operations are completed within the enclosed housing. This improves the equipment's safety, environmental friendliness, and overall integration. The equipment housing physically isolates high-speed moving parts and grinding dust from operators, preventing personal injury. The control module enables automated and coordinated control of all actions, and the feeding mechanism exchanges workpieces with the outside through the feed port.

[0020] When the rotary table rotates to exchange workpieces on the inside and outside, the opening and closing plate fixed to it rotates accordingly. When a workpiece enters the equipment, the opening and closing plate rotates to the position where the material inlet is closed; when workpieces need to be exchanged, the opening and closing plate opens the material inlet as the table rotates. This enhances the equipment's sealing performance, better preventing dust escape and noise transmission during non-workpiece exchange periods, thus improving safety and environmental performance.

[0021] Optionally, the support base is further provided with a limiting device, which includes a limiting plate and a driving source. The driving source is used to drive the limiting plate to rise and fall, so that the limiting plate passes through or exits the mating slot.

[0022] By adopting the above technical solution, when the rotary table rotates to the designated position, the drive source drives the limit plate to rise and insert into the matching slot of the rotary table, which can effectively eliminate the slight shaking or displacement that may occur after the rotary table rotates to the designated position, improve the accuracy of feeding and processing, and reduce processing errors.

[0023] On the other hand, this application provides a grinding process for a fully automatic marine lock after casting, including the following steps: Loading and fixing steps: Place the workpiece on the positioning fixture of the rotating worktable of the loading mechanism, start the equipment, the rotating worktable rotates, and sends the workpiece directly above the support platform; the lifting source of the pressing mechanism drives the pressing rod to descend, pressing the workpiece onto the support platform; Automatic grinding steps: The control module controls the transfer mechanism to drive the clamping mechanism and the workpiece to move, so that the part of the workpiece to be processed contacts the grinding wheel of the first grinding device and the grinding head of the second grinding device in sequence for grinding; Material unloading and circulation steps: After grinding is completed, the clamping rod rises to release the workpiece and transfers the workpiece back to the rotary worktable. Then the rotary worktable rotates to turn the processed workpiece out of the equipment housing, and at the same time, the next workpiece to be processed is turned into the upper part of the support platform for the next workpiece processing.

[0024] By adopting the above technical solution, fully automated and continuous production is achieved through a cycle of three steps: loading and fixing, automatic grinding, and unloading and recycling. This process integrates multiple processes into a single clamping operation, ensuring extremely high machining accuracy. At the same time, because loading, unloading, and machining are carried out in parallel, production efficiency is greatly improved, labor costs are saved, and it is suitable for mass production.

[0025] Optionally, a programming step may be included before the automated grinding step: The workpiece is clamped and fixed using the clamping mechanism. The transfer mechanism is manually controlled to move the workpiece sequentially to the first grinding device and the second grinding device after being adjusted by the flipping component, and moves along the contour of the workpiece to be ground. The control module records the motion trajectory points of the transfer mechanism and generates a control program for the automatic grinding step.

[0026] By adopting the above technical solution, a flexible and precise program generation method for specific workpieces is provided. Through manual pulse teaching, the trajectory is taught using the equipment's own mechanism. The generated program can perfectly match the actual shape and size of the workpiece, as well as the specific kinematic parameters of the equipment, thereby enabling the processing of highly consistent products.

[0027] In summary, this application includes at least one of the following beneficial effects: 1. This application integrates the first grinding device and the second grinding device, avoiding multiple clamping of the workpiece, effectively reducing positioning deviation, making the grinding program accurately match the actual position of the workpiece, improving the fine grinding quality, and reducing the risk of scrap. 2. This application eliminates the need to transfer workpieces between multiple machines during processing, significantly reducing non-processing time, compressing process waiting time, freeing the production cycle from the limitations of logistics transfer speed, and significantly improving production efficiency; 3. This application enables continuous and smooth production, with a compact and lean processing flow, and can quickly complete the grinding after casting of fully automated marine locks, meeting the needs of high-efficiency production; 4. The transfer mechanism in this application drives the clamping mechanism to move, so that the workpiece to be processed can contact different grinding devices in sequence, realize various types of grinding tasks, and improve the flexibility and adaptability of processing.

[0039] The implementation principle of this embodiment is as follows: This grinding equipment integrates the first grinding device 42 and the second grinding device 43 with different functions into one machine, avoiding the transfer of workpieces between multiple machines and multiple clamping, thus reducing processing errors. At the same time, the transfer mechanism 3 can flexibly move the workpiece to different grinding positions, realizing continuous grinding processes, compressing the waiting time between different processing processes, improving production efficiency, and achieving a compact and lean processing flow, which is a significant improvement and enhancement compared to the prior art.

[0040] Example 2 The grinding process of the fully automatic marine lock after casting provided in this application embodiment includes the following steps: S1, Loading and fixing steps: Place the workpiece on the positioning fixture 55 of the rotating worktable 53 of the loading mechanism 5, start the equipment, the rotating worktable 53 rotates, and the workpiece is sent to the top of the bearing platform 32.

[0041] S2, Programming Steps: Use the clamping mechanism 2 to clamp and fix the workpiece. Manually control the transfer mechanism 3 to move the workpiece sequentially to the first grinding device 42 and the second grinding device 43 after adjustment by the flipping component 44, and move along the workpiece's grinding contour. The operator controls the transfer mechanism 3 to move the workpiece to different grinding positions.

[0042] The control module 62 records the motion trajectory points of the transfer mechanism 3 and generates a control program for the automatic grinding step.

[0043] S3, Automatic Grinding Step: The control module 62 controls the transfer mechanism 3 to drive the clamping mechanism 2 and the workpiece to move, so that the part of the workpiece to be processed sequentially contacts the grinding wheel 421 of the first grinding device 42 and the grinding head 431 of the second grinding device 43 for grinding. According to the previously generated control program, the control module 62 precisely controls the movement of the transfer mechanism 3, so that the grinding wheel 421 and the grinding head 431 grind the workpiece according to the preset trajectory.

[0044] S4, Unloading and Cycling Steps: After grinding is completed, the piston rod of the lifting source 212 retracts, causing the clamping rod 211 to rise and release the workpiece. The transfer mechanism 3 transfers the workpiece back to the rotary table, and then drives the rotary worktable 53 to rotate, turning the processed workpiece out of the equipment housing 6. At the same time, the next workpiece to be processed is turned into the support platform 32 directly above it for the next workpiece processing, thus realizing the processing cycle.

[0045] This grinding process achieves efficient and precise grinding of marine-grade locks after casting through automated loading, programming, grinding, and unloading steps. The control program generated by the programming steps ensures the accuracy and consistency of the grinding process, reducing errors from manual operation. The automated loading and unloading cycle improves production efficiency and reduces labor costs. Compared with existing technologies, it achieves a more compact and lean processing flow, improving product quality and production efficiency.
