Description

Technical Field

[0001] This utility model relates to the field of automatic tool changing equipment technology, and in particular to a grinding tool changing device and grinding system. Background Technology

[0002] Automated grinding equipment refers to equipment that uses automation technology to perform surface treatment processes such as grinding, polishing, and deburring. It is widely used in industries such as metal processing, plastics, wood, and electronics. Automated grinding equipment can significantly improve production efficiency and product quality while reducing labor costs and safety risks. During the grinding process, the cutting tool is in long-term contact with the workpiece surface. Friction and pressure cause the tool to gradually wear down, weakening its cutting or grinding ability. Worn tools reduce grinding efficiency, failing to achieve the expected surface treatment effect, and may lead to a decline in workpiece surface quality. Furthermore, severely worn tools can exert additional pressure on the equipment's spindle, robotic arm, or drive system, causing unstable equipment operation and increasing the risk of wear or damage. On the other hand, grinding different materials or achieving different processing goals requires the selection of different types of cutting tools or consumables. Therefore, to ensure processing quality and extend equipment life, it is necessary to replace the appropriate cutting tools in a timely manner.

[0003] In existing technologies, grinding equipment can use robots to change tools. This involves mounting the spindle on the tool end of the robot and having the robot move the spindle between the tool changing position and the working position. However, this requires reserving space for the robot to change tools, and the tool changing efficiency is relatively low. Utility Model Content

[0019] In one embodiment, the grinding system includes a force control component connected to the spindle drive of the grinding tool changing device for controlling the contact force during grinding operations.

[0020] The aforementioned grinding tool changing device and grinding system, with multiple tools mounted on the tool holder, uses a first drive component inside the tool magazine to position the tools as needed to the tool changing window. This avoids the tedious manual searching and installation of tools, shortens changeover time, and improves changeover efficiency.

(See attached diagram.) Figures 1 to 4 The grinding tool changing device provided in one embodiment of this utility model includes:

[0035] Tool magazine 100, tool holder 110 is provided inside the tool magazine 100, multiple grinding tools are detachably connected to the tool holder 110, and tool changing window 130 is provided on the surface of the tool magazine 100 opposite to the grinding tools.

[0036] The first drive assembly 120 is connected to the tool holder 110 and is used to drive the tool holder 110 to move within the tool magazine 100 so that at least one of the plurality of grinding tools is aligned with the tool changing window 130.

[0037] Spindle 200, the first end of spindle 200 is detachably connected to the grinding tool;

[0038] Spindle mounting base 210 is used to mount spindle 200;

[0039] The second drive assembly 220 is mounted on the spindle mounting base 210 and is connected to the spindle 200 for driving the spindle mounting base 210 to move between the grinding station and the tool changing station, wherein the tool changing station is arranged opposite to the tool changing window 130.

[0040] The tool magazine 100 refers to the space used to house and manage spare grinding tools, and may include, for example, Figures 1 to 2 The housing shown is used to house the tool holder 110, the first drive assembly 120, and other related components. The housing may have multiple openings for mounting the components housed inside, and these openings may be equipped with dustproof doors. The tool holder 110 is a component used to hold a grinding tool to be replaced or a replaced grinding tool; its shape and structure can be configured according to actual production needs. The spindle 200 is a component used to drive the rotation of the grinding tool. The spindle 200 can be connected to a motor drive, and the motor drives the spindle 200 and the tool to rotate to complete the grinding operation. The spindle 200 can be integrated with the motor. The first drive assembly 120 and the second drive assembly 220 may include one or more of a cylinder 121, a hydraulic system, or a motor. The first drive assembly 120 is connected to the tool holder 110 and can drive the tool holder 110 to rotate or translate in the tool magazine 100 so that the grinding tool is aligned with the tool changing window 130, or so that the empty space on the tool holder 110 is aligned with the tool changing window 130 to receive the replaced worn tool. The second drive assembly 220 is connected to the spindle mount 210 and can drive the spindle mount 210 to perform translational or rotational movements so as to switch between the grinding operation station and the tool changing station.

[0041] Multiple tools are mounted on the tool holder 110 of the aforementioned grinding tool changing device. Inside the tool magazine 100, the first drive assembly 120 positions the tools as needed in the tool changing window 130, avoiding the tedious manual searching and installation of tools, shortening changeover time, and improving efficiency. The tool magazine 100 can store various specifications and types of grinding tools, enabling rapid tool switching according to different process requirements without frequent manual tool changes. It is suitable for various complex machining tasks and allows the spindle 200 to automatically switch between the grinding station and the tool changing station, improving the continuity and automation level of equipment operation. The tool changing station is positioned opposite the tool changing window 130, making the space between the tool magazine 100 and the spindle 200 more compact. Driving the spindle 200 to move between the grinding station and the tool changing station eliminates the complex operations required for robot tool changing, simplifying the tool changing process. This grinding tool changing device efficiently changes grinding tools, improving the flexibility and production efficiency of grinding processes.

[0042] In one exemplary embodiment, the grinding station and the tool changing station are arranged around the spindle mounting base 210. The second drive assembly 220 includes a second rotary drive cylinder, which is connected to the spindle 200 for driving the spindle 200 to rotate between the grinding station and the tool changing station. Compared to linear motion switching, rotary motion is faster and smoother, allowing for rapid switching of the spindle 200's position between the grinding station and the tool changing station. This avoids complex linear motion or multi-axis linkage designs, saving equipment floor space and improving space utilization.

[0043] In one exemplary embodiment, the first drive assembly 120 includes a rotary drive member, and a tool holder 110 is driveably connected to the rotary drive member. The rotary drive member drives the tool holder 110 to rotate, and multiple grinding tools are arranged in a ring around the rotation axis of the tool holder 110. This can improve tool storage density, make full use of space, and the tool holder 110 can provide different grinding tools for different stations through rotation, thereby improving tool changing speed, simplifying the structure, and enabling multi-station machining.

[0044] In an exemplary embodiment, the first drive assembly 120 includes a horizontal drive member and a vertical drive member. The vertical drive member drives the tool holder 110 to move vertically, and the horizontal drive member drives the tool holder 110 to move horizontally. Independent horizontal and vertical drives can precisely move the tool holder 110 to the target position, shortening the tool change path and saving space.

[0045] In one exemplary embodiment, the tool holder 110 includes a pneumatic indexing plate, to which multiple grinding tools are detachably connected. The rotary drive includes a first rotary cylinder, which is driven by the pneumatic indexing plate to drive its rotation. The pneumatic indexing plate has high angular positioning accuracy, ensuring precise alignment of the tools after rotation to a designated position. Rotation allows for quick switching of different tools to the tool changing window 130. The first rotary cylinder provides power for simple and efficient switching, and the structure is relatively simple with few wearing parts, facilitating maintenance.

[0046] In one exemplary embodiment, a plurality of elastic tool holders 111 are provided on the edge of the pneumatic indexing plate. The elastic tool holders 111 are used to fix grinding tools. The elastic tool holders 111 fix the tools by elastic deformation, which can adapt to the slight changes in the size of the tools while maintaining a stable clamping force. By appropriate adjustment or adaptation, tools with slightly different shapes and sizes can be clamped without frequent changes of the clamps. This reduces the complexity of tool changing operations and improves flexibility and change efficiency.

[0047] In one exemplary embodiment, the grinding tool further includes a limiting component for fixing the spindle 200 after it has moved to the tool changing station. The limiting component precisely fixes the spindle 200 after it has moved to the tool changing station, ensuring the stability of the spindle 200's position and guaranteeing precise alignment between the spindle 200 and the tool during tool changing, thus improving tool installation accuracy.

[0048] In an exemplary embodiment, the limiting component includes a first clamping cylinder 230, which is fixedly connected to the mounting base of the spindle 200 and used to fix the spindle 200 when it moves to the tool changing station. The clamping cylinder 230 is a pneumatic component driven by compressed air to apply pressure to the workpiece to achieve a fixing or clamping function. The first clamping cylinder 230 allows for simple pneumatic control to limit the spindle 200, providing uniform and stable clamping force, is less susceptible to external environmental influences, and exhibits strong reliability under high-frequency repetitive operation.

[0049] In one exemplary embodiment, the limiting component further includes a second clamping cylinder, which is fixedly connected to the mounting base of the spindle 200 and is used to fix the spindle 200 when the spindle 200 moves to the grinding operation station.

[0050] In one exemplary embodiment, a desktop fixed self-changing tool magazine is provided, which can mount a spindle on a grinding tool position, allowing a robot to grasp workpieces for grinding. The tool magazine's grinding tool position is mounted on a turntable, enabling the spindle to be moved into the tool magazine for tool changing. Once the spindle is in position, the tool magazine can use a cyclic trajectory for tool changing without requiring secondary programming. This achieves independent consumable changing for a fixed spindle; simplifies control, allowing for PLC jog control; and is compatible with various spindles and consumables.

[0051] Working Principle: The grinding tool consists of a force control device and an automatic tool changer spindle. The force control device controls the grinding contact force. The automatic tool changer spindle drives the grinding consumable to rotate and can control the release or clamping of the consumable. The grinding tool is fixed on the tool table. A rotary cylinder is installed at the bottom of the tool table, which can rotate the grinding tool, causing the grinding consumable to move between the grinding position and the tool change position. Clamping cylinders are installed at the grinding position and the tool change position respectively, ensuring that the spindle will not move under external force after rotating to its correct position. The consumable is loaded onto a tool holder, which is distributed in a ring on a pneumatic indexing plate. The tool holder secures the consumable through its own elastic deformation. The pneumatic indexing plate changes its fixed angle with each air supply, moving the consumable for the next station to the tool change position. The pneumatic indexing plate is fixed to a moving module. The moving module consists of a cylinder and a slide rail 122, which can control the movement of the indexing plate in the X and Y directions. The combined control cylinder can replace the old consumable in the spindle with a new one.

[0052] The work process is as follows:

[0053] The moving module moves the indexing plate to the far end in the XY direction, which is the initial position.

[0054] Loading: Manually fill the tool holder inside the equipment with consumables. The rotary cylinder rotates, moving the grinding tool to the tool change position. The clamping cylinder locks the grinding tool in place. The moving module first moves along the X-axis, aligning the center of the consumable at the tool change position with the axis of the automatic tool changer spindle. Then it moves along the Y-axis, inserting the consumable into the automatic tool changer spindle's gripper. The automatic tool changer spindle clamps the consumable. Then the moving module moves along the X-axis, disengaging the consumable from the tool holder. The clamping cylinder releases, and the rotary cylinder rotates, moving the grinding tool to the grinding position. The clamping cylinder locks in place. Finally, the moving module resets, moving the indexing plate to its initial position. Tool loading is complete, and grinding can begin.

[0055] Tool Change: When the consumable on the grinding tool is worn and no longer meets the grinding requirements, a tool change is necessary. The clamping cylinder is released. The rotary cylinder rotates, moving the grinding tool to the tool change position. The clamping cylinder locks in place. The moving module first moves along the Y direction, aligning the empty tool holder at the tool change position with the consumable on the grinding tool. Then it moves along the X direction, inserting the empty tool holder into the consumable. The automatic tool changer spindle releases the consumable. Then the moving module moves along the Y direction, disengaging the consumable from the automatic tool changer spindle. The moving module resets, moving the indexing plate to its initial position. The indexing plate repositions, replacing the consumable at the tool change position with a new one. The automatic tool loading steps during the feeding process are repeated. Once the tool is loaded, grinding can begin.

[0056] The desktop-mounted self-changing tool magazine has sufficient space for tool rotation, preventing collisions with the frame and entanglement with internal wiring harnesses. The tool changing position is open, which will not interfere with the spindle tool changing, speeding up the tool changing process, simplifying the robot tool changing trajectory, and improving overall grinding efficiency. Manual tool changing in the magazine is highly efficient, allowing all tools to be changed at once. It does not rely on robot tool changing, allowing robots on the production line to grab workpieces or perform other operations, enabling more trajectory options.

[0057] In a second aspect, a grinding system is provided, including a grinding tool changing device as described in the first aspect or any embodiment of the first aspect, the grinding tool changing device being used to replace consumables of the grinding system.

[0058] In one embodiment, the grinding system includes a force control component connected to the spindle drive of the grinding tool changing device for controlling the contact force during grinding operations.

[0059] The force control component may include a force sensor, a controller, and an actuator. The force sensor, actuator, and controller are electrically connected. The force sensor may be a piezoelectric sensor, strain gauge sensor, or torque sensor, etc., used to measure the actual contact force. The controller is used to process the sensor signal and generate control commands, and adjust its output according to the difference between the actual contact force and the required contact force. The actuator may be a servo motor, cylinder, or hydraulic system, which adjusts the contact force by controlling the feed rate or pressure.

[0060] The control of each component in each embodiment of this utility model can be achieved by existing technology, and will not be described in detail here.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
