Description

Technical Field

[0001] This utility model relates to the field of grinding, specifically a servo-driven tool-setting device. Background Technology

[0002] In the field of machining, grinding is a common precision machining method. It removes material through the relative motion between the grinding wheel and the workpiece to achieve the desired dimensions and surface quality. The tool setting device, as a crucial component of grinding, directly affects the machining outcome through its performance and accuracy. Traditional tool setting methods mainly include the following:

[0003] Manual tool setting: The operator moves the grinding wheel near the workpiece by visual inspection and touch, and then slowly adjusts the position of the grinding wheel until it contacts the workpiece. This method requires a high level of experience and skill from the operator, and improper operation can easily lead to tool collision. For example, manual tool setting is even more difficult when machining workpieces with complex shapes or high precision requirements, and the slightest mistake can lead to machining failure.

[0004] Automatic Tool Setting: With technological advancements, automatic tool setting devices have emerged. These devices automatically detect the distance between the grinding wheel and the workpiece using sensors and measurement systems, then control the grinding wheel to move to the appropriate position. However, existing automatic tool setting devices have several problems. Firstly, their measurement accuracy is limited, making it difficult to accurately determine the relative position of the grinding wheel and the workpiece, resulting in low tool setting precision. For example, some automatic tool setting devices using photoelectric sensors may exhibit measurement errors when ambient light changes or when the workpiece surface has uneven reflectivity. Secondly, the tool setting process is complex, requiring multiple steps and adjustments, leading to prolonged setting time. For instance, some automatic tool setting devices require coarse positioning followed by fine positioning, with each positioning step requiring time for measurement and adjustment, significantly reducing the efficiency of grinding operations.

[0005] In addition to the problems mentioned above, existing tool setting devices also have shortcomings in adaptability. Different grinding equipment and workpiece types have different requirements for tool setting devices, but existing devices often struggle to meet diverse needs. For example, for some large or specially shaped workpieces, existing tool setting devices may not be able to perform accurate tool setting operations, requiring additional adjustments or modifications. Furthermore, the reliability and stability of existing tool setting devices need improvement. Under prolonged operation or harsh working environments, malfunctions or increased measurement errors may occur, affecting machining quality and production efficiency. Utility Model Content

[0006] The present invention aims to overcome the defects of the prior art and provide a servo flip tool setting device, which solves the problems of inaccurate positioning and long tool setting time in the existing tool setting methods.

[0007] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0008] A servo-driven tool-setting device is characterized by comprising a servo motor, a reducer, a measuring grating, and an automatic tool-setting device mounted directly in front of the grinding wheel. The servo motor is connected to the automatic tool-setting device via the reducer and is used to drive the automatic tool-setting device to rotate to the front of the grinding wheel. The measuring grating is mounted on the automatic tool-setting device and is used to detect the workpiece position and transmit the detection signal to the control system. The control system is electrically connected to the servo motor and the measuring grating and is used to receive the signal from the measuring grating and control the action of the servo motor to realize that the grinding wheel automatically approaches the workpiece for grinding.

[0009] The servo-driven flip-over tool setting device is characterized in that: the automatic tool setting device includes a flipping mechanism and a tool setting component mounted on the flipping mechanism; the servo motor drives the flipping mechanism to flip via a reducer; and the measuring grating is mounted on the tool setting component to detect the relative position between the workpiece and the tool setting component.

[0010] The servo-driven tool-setting device is characterized in that: the flipping mechanism includes a flipping shaft and a flipping bracket fixed on the flipping shaft; the tool-setting component is mounted on the flipping bracket; and the servo motor drives the flipping shaft to rotate through a reducer, thereby causing the flipping bracket and the tool-setting component to flip to the front of the grinding wheel.

[0011] The servo-driven flip tool setting device is characterized in that: the tool setting component includes a tool setting head and a connector connecting the tool setting head and the flipping bracket; the measuring grating is mounted on the tool setting head; the tool setting head is fixed to the flipping bracket by the connector and can flip together with the flipping bracket, and when flipped to the front of the grinding wheel, the measuring grating is facing the workpiece.

[0012] The servo-driven tool-setting device is characterized in that: the control system calculates the distance between the workpiece and the grinding wheel surface based on the workpiece position data detected by the measuring grating and the grinding wheel diameter, controls the grinding wheel feed mechanism to move so that the grinding wheel quickly approaches the workpiece surface at 0.1mm, and then changes to a slow approach. At the same time, the grinding wheel current is detected. When the grinding wheel current value is greater than 0.2 amperes under no-load conditions, the approach is completed and grinding begins.

[0013] The servo-driven tool-setting device is characterized in that: the grinding wheel feed mechanism includes a feed motor and a feed screw connected to the feed motor; the grinding wheel is mounted on the feed screw; the control system calculates the distance between the workpiece and the grinding wheel surface based on the workpiece position data detected by the measuring grating and the grinding wheel diameter, and then controls the feed motor to drive the feed screw to rotate, causing the grinding wheel to move axially along the feed screw, quickly approaching the workpiece surface at 0.1mm, and then slowing down the approach. At the same time, the grinding wheel current is detected. When the grinding wheel current value is greater than 0.2 amperes under no-load conditions, the feed motor is controlled to stop rotating, the approach is completed, and grinding begins.

[0014] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a servo-driven flipping tool setting device. By rapidly detecting the workpiece position through a measuring grating, a servo motor quickly drives the flipping mechanism to move the grinding wheel near the workpiece surface, significantly shortening the tool setting time. Simultaneously, by employing a combination of fast and slow approach methods, tool setting efficiency is further improved while ensuring tool setting accuracy. This significantly enhances the overall efficiency of grinding processes, better meeting the demands of modern high-efficiency production and improving enterprise production efficiency.

Furthermore, for workpieces of different shapes, sizes, and materials, the tool setting device of this invention can accurately detect their position through a measuring grating, completing the tool setting operation without complex adjustments or modifications.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0020] like Figure 1 , 2As shown: A servo-driven tool setting device includes a servo motor 1, a reducer 2, a measuring grating 3, and an automatic tool setting device mounted in front of the grinding wheel. The servo motor is connected to the automatic tool setting device through the reducer and is used to drive the automatic tool setting device to rotate to the front of the grinding wheel. The measuring grating is set on the automatic tool setting device and is used to detect the workpiece position and transmit the detection signal to the control system. The control system is electrically connected to the servo motor and the measuring grating and is used to receive the signal from the measuring grating and control the action of the servo motor to realize the automatic approach of the grinding wheel to the workpiece for grinding.

[0021] The automatic tool setting device includes a flipping mechanism 4 and a tool setting component mounted on the flipping mechanism. The servo motor drives the flipping mechanism to flip via a reducer. The measuring grating is mounted on the tool setting component to detect the relative position between the workpiece and the tool setting component.

[0022] The flipping mechanism includes a flipping shaft and a flipping bracket fixed on the flipping shaft. The tool setting component is mounted on the flipping bracket. The servo motor drives the flipping shaft to rotate through a reducer, thereby causing the flipping bracket and the tool setting component to flip to the front of the grinding wheel.

[0023] The tool setting component includes a tool setting head and a connector connecting the tool setting head and the flipping bracket. The measuring grating is mounted on the tool setting head, and the tool setting head is fixed to the flipping bracket by the connector. It can flip together with the flipping bracket and, when flipped to be directly in front of the grinding wheel, makes the measuring grating face the workpiece.

[0024] The control system calculates the distance between the workpiece and the grinding wheel surface based on the workpiece position data detected by the measuring grating and the grinding wheel diameter, and controls the grinding wheel feed mechanism to move so that the grinding wheel quickly approaches the workpiece surface at 0.1 mm, and then slows down the approach. At the same time, the grinding wheel current is detected. When the grinding wheel current value is greater than 0.2 amperes under no-load conditions, the approach is completed and grinding begins.

[0025] The grinding wheel feed mechanism includes a feed motor and a feed screw connected to the feed motor. The grinding wheel is mounted on the feed screw. The control system calculates the distance between the workpiece and the grinding wheel surface based on the workpiece position data detected by the measuring grating and the grinding wheel diameter. Then, it controls the feed motor to drive the feed screw to rotate, causing the grinding wheel to move axially along the feed screw, quickly approaching the workpiece surface at 0.1 mm. Then, it slows down the approach and simultaneously detects the grinding wheel current. When the grinding wheel current value is greater than 0.2 amperes under no-load conditions, the feed motor is controlled to stop rotating, the approach is completed, and grinding begins.

[0026] This invention employs a high-precision measuring grating to detect the workpiece position. The grating boasts extremely high resolution and measurement accuracy, enabling precise acquisition of the relative positional information between the workpiece and the grinding wheel. Through precise measurement by the grating, combined with the precise control of a servo motor, the grinding wheel can be moved quickly and accurately to the vicinity of the workpiece surface, avoiding the collision phenomenon caused by human error during manual tool setting. Collisions not only damage the tool and workpiece but can also lead to safety accidents, severely impacting production efficiency and machining quality. This invention's high-precision tool setting method effectively solves this problem, improving machining safety and reliability while reducing production costs.

[0027] In traditional grinding processes, tool setting often requires manual operation, which is not only time-consuming and labor-intensive but also susceptible to the limitations of the operator's skill level and experience. The automatic tool setting device of this invention automates the tool setting process. The operator only needs to start the equipment, and the device automatically completes the tool setting operation without human intervention. This significantly reduces the operator's workload and increases the level of automation in production. Simultaneously, the automated tool setting method reduces the impact of human factors on machining quality, ensuring the stability and consistency of the machining process, and further improving production efficiency and product quality.

[0028] Because this invention can precisely control the relative position of the grinding wheel and the workpiece, it avoids machining errors caused by inaccurate tool setting, thereby significantly improving the quality of grinding. The machined workpieces have higher dimensional accuracy and better surface quality, meeting higher processing standards.
