Description

Technical Field

[0001] This utility model relates to the field of grinding machine tool technology, specifically to an automatic loading and unloading grinding machine tool. Background Technology

[0002] For automated casting grinding applications requiring high cycle times, the grinding equipment must simultaneously possess both automatic loading / unloading and grinding functions. There are two existing solutions. The first solution uses a six-joint robotic arm to perform both loading / unloading and grinding functions concurrently. The drawback of this solution is that the fixture design must consider the reachability and obstacle avoidance requirements of the robotic arm under both working conditions, making fixture design difficult or even impossible, and the cycle time cannot meet the requirements. The second solution uses a separate automated loading / unloading system combined with a dedicated grinding machine to achieve automated loading / unloading and grinding functions separately. The main drawbacks of this solution are: 1. The working space of the loading and unloading equipment overlaps with the manual operating space of the grinding machine. In scenarios such as debugging the grinding program, changing grinding tools, and manual loading and unloading, the operator is within the working range of the loading and unloading robot, resulting in limited working space, inconvenient operation, and safety hazards; 2. High production costs and large system footprint; 3. Long on-site installation and debugging cycle; 4. The safety door of the grinding machine needs to be opened every time the material is automatically changed. Metal dust may overflow from the safety door, leading to the accumulation of metal dust in the workshop and potentially causing a dust explosion. Utility Model Content

[0065] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0066] Example

[0067] Combined with appendix Figure 1-3An automatic loading and unloading grinding machine includes a base 9 and a clamping assembly 5, a cutter head shaft assembly 6 and a loading and unloading assembly integrated on the base 9. The clamping assembly 5 and the loading and unloading assembly are respectively arranged on both sides of the cutter head shaft assembly 6. The cutter head shaft assembly 6 is raised by a frame 17. The clamping assembly 5 is provided with a matching track 8 and moves at the end of the loading and unloading assembly and the track 8. The base 9 is provided with a fully enclosed protective sheet metal and a dust collection device.

[0068] The base 9 serves as the foundation platform for the entire equipment, highly integrating all key functional modules. This fundamentally solves the problems of large system footprint and long installation and commissioning cycles, while reducing overall costs. The cutter head shaft assembly 6, acting as the grinding actuator, is elevated by the support frame 17. This provides movement space for the clamping assembly 5 below and facilitates dust settling and collection. The clamping assembly 5 is equipped with a track 8, allowing it to move between the cutter head shaft assembly 6 (processing position) and the loading / unloading assembly (loading / unloading position). This design cleverly separates the loading / unloading area from the grinding area while maintaining a close connection, avoiding conflicts between loading / unloading equipment and manual operation space in traditional solutions, significantly improving operational safety and convenience. The loading / unloading assembly is fixedly located on one side of the cutter head shaft, specifically responsible for gripping and placing castings. Its fixed position and proximity to the processing area, combined with the movable clamps, achieve efficient material flow. Finally, the fully enclosed protective sheet metal and dust collection device around the equipment work together to completely enclose the grinding process in a controlled environment, effectively preventing metal dust from spilling out of the workshop, solving the safety hazards of dust accumulation and explosion, and ensuring a clean working environment.

[0069] The clamp assembly 5 includes multiple chucks 10, and each chuck 10 is rotatably connected to the clamp moving seat 13 via the clamp shaft moving part 11 and the clamp shaft base 129. The clamp moving seat 13 is slidably engaged with the track 8.

[0070] The fixture moving base 13 is the core support platform. It slides with the track 8, allowing the entire fixture assembly 5 to move precisely and smoothly along the track 8 between the cutter head shaft assembly 6 (grinding station) and the loading / unloading assembly (loading / unloading station). This is crucial for achieving spatial separation and automated flow. The fixture shaft base 129, mounted on the fixture moving base 13, provides a stable support foundation and rotation axis for the rotational movement of the chuck 10. The fixture shaft moving part 11 (typically including a drive motor, reduction mechanism, etc.) is connected to the fixture shaft base 129, and its core function is to drive the chuck 10 to rotate around the axis. This rotational capability is essential, enabling the chuck 10 to adjust the angle of the casting according to the needs of the grinding process (achieving multi-faceted grinding), or to adjust its posture at the loading / unloading position so that the loading / unloading robot can grip or place the workpiece more efficiently and reliably. Finally, the design of multiple chucks 10 directly enhances the parallel processing capability of the equipment, allowing multiple castings to be clamped simultaneously. While one casting is being ground, the other chucks 10 can be in loading / unloading or waiting state, thereby significantly improving the overall cycle time and production efficiency of the equipment.

[0071] The fixture moving seat 13 includes a cradle shaft 4, the cradle shaft 4 includes a rotating plate 18, the rotating plate 18 is rotatably connected to the fixture moving seat 13 body via a rotating motor 19, and the fixture shaft base 129 is fixedly connected to the rotating plate 18.

[0072] The fixture moving base 13 body is the basic frame and load-bearing body for the entire fixture assembly 5 to move along the track 8. The rotary motor 19 is the core drive source, directly providing rotational power. The rotating plate 18, as a key moving component of the cradle shaft 4, is rotatably connected to the fixture moving base 13 body on one side via bearings and other mechanisms, allowing the rotating plate 18 to rotate relative to the body; simultaneously, the fixture shaft base 129 is fixed to the other side of the rotating plate 18. Therefore, the rotational output of the rotary motor 19 directly drives the rotating plate 18 (along with the fixture shaft base 129 on it) to rotate around the axis. The core function of this design is: after the fixture assembly 5 is moved into place, the rotation of the cradle shaft 4 drives the entire chuck 10 mechanism (including the clamped casting) mounted on the fixture shaft base 129 to adjust its angle. This angle adjustment capability is crucial, as it allows castings to flexibly change their posture at the grinding station to meet the process requirements of grinding complex curved surfaces or multiple angles, significantly improving the flexibility and adaptability of grinding. At the loading and unloading station, the posture of the castings can also be adjusted by rotation, making it easier for the loading and unloading components to perform gripping or placement operations more efficiently and reliably.

[0073] A moving motor 20 is installed on the track 8, and the moving motor 20 is connected to the clamp moving seat 13 through a screw and nut structure.

[0074] Track 8 not only provides a precise movement path and guiding support for the fixture moving seat 13, ensuring the stability and accuracy of its linear motion trajectory, but also serves as the mounting base for the moving motor 20. The moving motor 20 is the core power source driving the fixture assembly 5 to switch workstations (moving between the loading / unloading position and the grinding position) on track 8, converting electrical energy into rotational mechanical energy. The lead screw and nut structure is the key mechanical device for realizing motion conversion: the rotational motion of the lead screw (usually connected to the motor output shaft) is converted into precise and smooth linear motion of the nut and fixture moving seat 13 along the lead screw axis through the precisely matched nut (fixed on the fixture moving seat 13). This transmission method has advantages such as high positioning accuracy, good rigidity, and self-locking, ensuring that the fixture assembly 5 can be firmly held at the target workstation (grinding position or loading / unloading position) when stopped, without shifting due to gravity or vibration. This is crucial for ensuring grinding accuracy and the reliability of loading / unloading operations. At the same time, the lead screw and nut structure is generally highly efficient, helping to achieve rapid, cycle-compliant workstation switching.

[0075] The loading and unloading assembly includes an automatic loading and unloading station 15 and a manual loading and unloading station 16 located on both sides. The automatic loading and unloading station 15 is equipped with a loading and unloading robot 1 and an automatic material tray, while the manual loading and unloading station 16 is equipped with a manual material tray.

[0076] The loading and unloading assembly is divided into two separate automatic loading and unloading stations 15 and manual loading and unloading stations 16. This physical separation is a key design feature that addresses the "overlapping workspace" problem in the background technology. The automatic loading and unloading station 15 is specifically designed for fully automated operation. Its core component is the loading and unloading robot 1, which is responsible for automatically gripping (unloading polished parts) and placing (loading parts to be polished) castings on the fixture assembly 5. It is the core actuator for achieving high-cycle continuous production. The automatic material tray works in conjunction with the robot to orderly store and supply raw castings to be polished, as well as receive and store finished castings that have been polished, providing the robot with a stable and batch-produced material source. The manual loading and unloading station 16 is used for scenarios requiring human intervention. Its core component is the manual material tray, which provides an operator 21 with a platform for safely and conveniently loading and unloading castings manually. The manual and automatic workstations are set up on opposite sides, ensuring that when debugging programs, changing tools, conducting small-batch trial production, or handling special workpieces, the operator 21 is completely outside the robot's automatic operation range, thus completely eliminating safety hazards and providing an independent and spacious operating space.

[0077] The loading / unloading robot 1 is equipped with a finished product storage device 7. Receiving finished products: After the loading / unloading robot 1 removes a polished casting (finished product) from the chuck 10 of the clamping assembly 5, it can immediately place it onto the finished product storage device 7. Orderly temporary storage / buffering: During automated continuous operation, this device serves as a temporary storage area or buffer zone for finished castings after they leave the clamping fixture and before they are transported or collected. This allows the robot to quickly unload finished products without waiting for immediate removal by an external system, thus maintaining a high-efficiency continuous operation cycle. Space optimization and smooth workflow: By specifically placing the finished product storage area within the robot's reach, the robot's movement path is optimized, reducing unnecessary movement distances and time, making the "remove finished product -> place finished product" operation process smoother and more efficient. Clear division of labor with the automatic material tray: The finished product storage device 7 and the previously mentioned automatic material tray (usually used to store blanks to be polished) have a clear functional division: one is dedicated to blanks (input), and the other is dedicated to receiving finished products (output), together constructing a complete automated material flow. Enhanced automation and enclosure: With a dedicated finished product storage device 7, the loading and unloading robot 1 can complete all operations within the protective enclosure, from picking up the blank, placing it into the fixture, picking up the finished product from the fixture, and placing it into the finished product device. This reduces the frequency of opening the safety door due to the need for external manual intervention or transfer of finished products, helps to better maintain the enclosed environment, and reduces the chance of dust spillage.

[0078] The cutter head shaft assembly 6 is movably connected to the overhead frame 17 via a dual-axis guide rail on the overhead frame 17.

[0079] The overhead platform 17 serves as the support platform for the entire cutter head spindle assembly 6, elevating it to create space below for the jig assembly 5 to move. The dual-axis guide rail is a crucial motion guiding mechanism, rigidly mounted on the overhead platform 17. The cutter head spindle assembly 6 (including the drive motor, spindle, and grinding tool) is "movably connected" to this dual-axis guide rail via sliding components. This "dual-axis" design (typically referring to two parallel precision linear guide rails) offers significant advantages over a single-axis design: it provides extremely high rigidity and stability, effectively resisting the complex cutting forces generated during grinding (especially radial forces and overturning moments), preventing vibration or displacement of the cutter head spindle assembly 6 during machining, and ensuring grinding accuracy and surface quality. Simultaneously, the dual-axis guide rail provides extremely precise linear motion guidance, allowing the cutter head spindle assembly 6 to move precisely and smoothly in a direction parallel to the guide rail (typically the X or Y axis) under the drive of a drive unit (such as a servo motor + ball screw, not mentioned in the figure but usually used together). This mobility is crucial for achieving grinding in different locations, machining complex contours, or tool compensation, greatly expanding the equipment's machining range and flexibility. Furthermore, this movable connection method also facilitates equipment installation, commissioning, and tool setting operations.

[0080] A reversing device 3 is connected to a dual-axis guide rail. The reversing device 3 is fixedly mounted on the overhead frame 17. The robot removes the product with one side polished from the fixture assembly 5 and places it in the clamping mechanism of the reversing device 3. The flipping mechanism drives the clamping mechanism to flip the product and place it in the positioning mechanism. Then the robot picks up the flipped product and puts it into the fixture assembly. The reversing device 3 is existing technology, which achieves workpiece reversal through tooling fixation and motor flipping.

[0081] The grinding machine consists of a machine base 9, a blank feeding device 2, a finished product storage device 7, a loading and unloading robot 1, a reversing device 3, a grinding robot, a custom fixture, grinding tools, and a fully enclosed sheet metal frame.

[0082] The blank feeding device 2 is used to store blanks and can be composed of a material tray, a conveyor belt, or other mechanisms. This embodiment uses a double-layer material tray feeding mechanism as an example. This mechanism consists of a material tray shaft, a material tray shaft, a custom material tray, and a custom material tray. The material tray shaft and the material tray shaft are both translational motion shafts. The bases 9 of the material tray shaft and the material tray shaft are both fixed on the machine tool base 9. The custom material trays are respectively fixed on the moving parts of the material tray shaft and the material tray shaft.

[0083] The finished product after polishing can be placed back into the material tray in the blank feeding device 2, or it can be placed into the specially set finished product storage device 7. In this embodiment, a separate conveyor belt is set as the finished product storage device 7.

[0084] The loading and unloading robot 1 consists of a six-joint robotic arm, a gripper cylinder, a custom gripper, and a control system. The gripper cylinder is fixed to the end flange of the six-joint robotic arm, and the custom gripper is fixed to the gripper cylinder.

[0085] The grinding robot consists of three orthogonally arranged translational axes (X, Y, Z), four rotary axes (cutter head axis, cradle axis 4, and two fixture axes), grinding tools, and custom fixtures. The Y-axis base 9 is fixed to the machine tool base 9, the Z-axis base 9 is fixed to the Y-axis moving part, the cutter head axis base 9 is fixed to the Z-axis moving part, and the grinding tools are mounted in a ring on the cutter head axis moving part. The X-axis base 9 is fixed to the machine tool base 9, the cradle axis 4 base 9 is fixed to the X-axis moving part, and the two fixture axes bases 9 are fixed to the cradle axis 4 moving part. Custom fixtures are mounted on the moving parts of the two fixture axes respectively. More fixture axes can be added as needed.

[0086] The fully enclosed sheet metal structure has a safety door at the manual operation position, and doors and windows for maintenance and repair purposes in other positions. It also has a metal dust collection device at the top and a metal particle collection device at the bottom.

[0087] System workflow:

[0088] (1) Operator 21 places the blank to be polished on the material tray of the blank feeding system at the loading position outside the fully enclosed sheet metal. Then the material tray shaft transports the material tray full of blanks to the inside of the fully enclosed sheet metal.

[0089] (2) The loading and unloading robot 1 takes the semi-finished product from one of the clamping shafts of the grinding robot, takes the finished product from the other clamping shaft, puts the semi-finished product into the reversing device 3, and puts the finished product into the finished product storage device 7.

[0090] (3) The loading and unloading robot 1 takes the blank from the material tray, takes the semi-finished product from the reversing device 3, puts the blank into the fixture of the grinding machine, and puts the semi-finished product into the fixture of the grinding machine.

[0091] (4) Grinding robots grind the blanks and semi-finished products;

[0092] (5) Return to step (2) and repeat.
