Description

Technical Field

[0001] This utility model relates to the field of tool setting device technology, and in particular to a high-precision tool setting device. Background Technology

[0002] In CNC machine tool machining, the length and positional accuracy of the cutting tool directly affect the machining quality of the workpiece. To ensure the stability and consistency of machining, it is necessary to accurately measure and compensate the cutting tool before machining. Existing tool setting devices can be roughly divided into three categories: manual reading type, micro switch type, and high-precision sensor type.

[0003] Traditional manual reading devices typically rely on dial indicators, micrometers, or rulers to measure tool length. While these methods are simple in structure, they are highly dependent on operator judgment, making them prone to human error, resulting in poor repeatability and consistency, and compromising machining efficiency. Microswitch devices use mechanical contacts for detection; a trigger signal is generated when the tool tip contacts the switch. This approach reduces manual operation to some extent, but it only provides one contact signal and cannot achieve precise measurement of tool length. Furthermore, mechanical contacts are prone to wear with frequent use, resulting in limited reliability and high maintenance costs.

[0004] Therefore, a high-precision tool setting device is proposed to solve the above problems. Utility Model Content

[0007] Furthermore, the adjustment assembly includes a lever and a fixed base, the lever is movably mounted on the fixed base, the blade abuts against one end of the lever, and the other end of the lever is connected to the sensor.

[0008] Furthermore, the adjustment assembly also includes an elastic element and a scale. The elastic element is mounted on the fixed base, and the other end of the elastic element is connected to the lever. The scale is located on the side of the lever away from the cutter head, and the scale is connected to the sensor.

[0009] Furthermore, the adjustment assembly also includes a connecting block, which is inserted into the lever, with one end of the connecting block abutting against the blade and the other end of the connecting block connected to the elastic element.

[0010] Furthermore, it also includes a support plate, which is fixedly installed on the fixed base. The support plate has a U-shaped groove and is configured to support the lever.

[0011] Furthermore, the fixing base has a limiting groove, which is located below the dial; Specifically, when both ends of the lever are on the same horizontal line, the lower end of the dial is located within the limiting groove.

[0012] Beneficial effects: This utility model discloses a high-precision tool setting device, comprising: a tool holder for mounting a tool head; an adjustment component disposed below the tool holder, with the lower end of the tool head abutting against the adjustment component and configured to adjust the extension / retraction length of the tool head; and a sensor connected to the output end of the adjustment component for acquiring the displacement of the adjustment component. When the tool head abuts against the adjustment component, the sensor acquires the displacement of the adjustment component and outputs a signal corresponding to the length of the tool head to a receiving device. This tool setting device, by setting an adjustment component below the tool holder, enables the tool head to generate a measurable displacement when contacting the adjustment component.

[0018] Reference Figures 1 to 4 This utility model discloses a high-precision tool setting device, comprising: Tool holder 100 is used to mount tool head 110; An adjustment component 200 is disposed below the cutter holder 100, and the lower end of the cutter head 110 abuts against the adjustment component 200 and is configured to adjust the extension length of the cutter head 110. Sensor 300 is connected to the output terminal of the adjustment component 200 and is used to collect the displacement of the adjustment component 200; When the cutter head 110 abuts against the adjustment component 200, the sensor 300 collects the displacement of the adjustment component 200 and outputs a signal corresponding to the length of the cutter head 110 to the receiving device; The adjustment assembly 200 includes a lever 220 and a fixed base 210. The lever 220 is movably mounted on the fixed base 210. The blade 110 abuts against one end of the lever 220, and the other end of the lever 220 is connected to the sensor 300. The adjustment assembly 200 also includes an elastic element 400 and a dial 500. The elastic element 400 is mounted on the fixed base 210, and the other end of the elastic element 400 is connected to the lever 220. The dial 500 is located on the side of the lever 220 away from the cutter head 110, and the dial 500 is connected to the sensor 300. The adjustment assembly 200 also includes a connecting block 230, which is inserted into the lever 220. One end of the connecting block 230 abuts against the cutter head 110, and the other end of the connecting block 230 is connected to the elastic member 400.

[0019] This embodiment provides a high-precision tool setting device, which mainly includes a tool holder 100, an adjustment component 200, a sensor 300, and a connecting block 230. The tool holder 100 is used to install and fix the tool head 110, ensuring that the tool head 110 is stably positioned during tool setting. The adjustment component 200 is located below the tool holder 100, and its core components are the lever 220 and the fixed base 210. The lever 220 is movably mounted on the fixed base 210 around a fixed fulcrum. One end of the lever 220 contacts the tool head 110 and transmits the force of the tool head 110 through the connecting block 230. The other end of the lever 220 is linked to the dial 500 and the sensor 300. An elastic element 400 is provided at the end of the lever 220 that contacts the tool head 110. One end is fixed to the fixed base 210, and the other end is connected to the connecting block 230 to provide preload force and reset force. When the tool head 110 applies force to the lever 220, the elastic element 400 undergoes elastic deformation, causing the lever 220 to be displaced by the force, and automatically resets after the force is released.

[0020] A dial 500 is located at the end of the lever 220 furthest from the cutter head 110 and is connected to a sensor 300. The sensor 300 can be a photoelectric encoder, a magnetic encoder, or an angle sensor 300, used to acquire the angular or linear displacement signal of the dial 500 in real time. After the displacement of the lever 220 is transmitted to the sensor 300 via the dial 500, the signal is converted into the length information of the cutter head 110 by the processing unit and output to the receiving device to realize the digital display or further control of the cutter length.

[0021] During operation, when the lower end of the cutter head 110 abuts against the connecting block 230, the applied force causes the lever 220 to rotate around a fixed fulcrum. The rotation of the lever 220 drives the dial 500 to move. The sensor 300 collects the displacement signal of the dial 500, while the elastic element 400 undergoes compression deformation and stores a restoring force, causing the lever 220 to automatically return to its initial position after the force on the cutter head 110 is released. Through the mechanical amplification effect of the lever 220 structure, even the minute displacement of the cutter head 110 can be accurately measured, thereby ensuring the accuracy and repeatability of tool setting.

[0022] In this embodiment, by adjusting the tool holder 100, the tool head 110 extends axially to the position to be measured, preparing for tool setting measurement. Subsequently, the lower end of the tool head 110 abuts against the connecting block 230, transmitting the force of the tool head 110 to the connecting block 230. Under the action of the force of the tool head 110, the lever 220 displaces around the fixed fulcrum, while simultaneously compressing the elastic element 400 connected to one end of the lever 220. The elastic element 400 stores the restoring force, ensuring that the lever 220 returns to its initial position. As the lever 220 moves, its other end drives the dial 500 to displace accordingly. The displacement of the dial 500 is collected in real time by the sensor 300. The sensor 300 transmits the acquired signal to an external receiving device. The receiving device calculates the actual length of the tool head 110 based on the sensor 300 signal, realizing the digital display or further control of the length of the tool head 110. In this way, the minute displacement of the cutter head 110 can be accurately measured, ensuring the accuracy of the cutter setting. At the same time, the reset function of the elastic element 400 ensures that the lever 220 returns to its initial position after operation, providing convenience for the next measurement.

[0023] This embodiment features a simple and reliable structure, and is compatible with different specifications and types of tool heads 110. By adjusting the preload force of the elastic element 400 or the length of the lever 220, different measurement ranges and accuracy requirements can be met, making it suitable for various CNC machine tools or scenarios requiring precise tool length measurement.

[0024] The high-precision tool setting device also includes a support plate 600, which is fixedly installed on the fixed base 210. The support plate 600 has a U-shaped groove 610 and is configured to support the lever 220. The fixed base 210 has a limiting groove 700, which is located below the dial 500; When both ends of the lever 220 are on the same horizontal line, the lower end of the dial 500 is located within the limiting groove 700.

[0025] Based on the aforementioned high-precision tool setting device, this embodiment further optimizes the support and limiting structure of lever 220. To ensure the stability and accuracy of lever 220 during operation, a support plate 600 is added to the fixed base 210. The support plate 600 has a U-shaped groove 610 for reliable support and guidance of lever 220. This structure effectively prevents lateral displacement or jitter of lever 220 during movement, thereby improving the stability of displacement transmission and the reliability of measurement results. Simultaneously, a limiting groove 700 is designed on the fixed base 210 and positioned below the dial 500. When lever 220 is in a horizontal state, the lower end of dial 500 is precisely within the limiting groove 700, used to mark the zero position. This design not only helps operators quickly determine the state of lever 220 but also facilitates zero-point calibration of the device.

[0026] During the tool setting operation, the tool head 110 acts on the connecting block 230 and drives the lever 220 to rotate around the fulcrum. The movement of the lever 220 is further supported by the U-shaped groove 610 on the support plate 600, reducing the sway or displacement error of the lever 220 caused by off-center loading. As the lever 220 rotates, its other end drives the dial 500 to move accordingly. The limiting groove 700 below the dial 500 serves as the zero-position reference. When both ends of the lever 220 return to the same horizontal line, that is, when the elastic element 400 resets, the lever 220... When the device returns to its initial state, the lower end of the dial 500 naturally falls into the limiting groove 700. The limiting groove 700 is designed for two main purposes: first, to mechanically limit the travel of the dial 500 as the lever 220 rotates, preventing overtravel from impacting the dial 500; second, by partially accommodating the lower edge of the dial 500 within the limiting groove 700 when the lever 220 is in a horizontal state, the device achieves spatial stacking and reuse, thereby reducing the overall height and external dimensions of the device and improving its miniaturization level.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
