Description

Technical Field

[0001] The present invention relates to the field of tool detection equipment, and in particular to an integrated device and method for tool disassembly and assembly and wear detection. Background Art

[0002] Ceramic matrix composites (CMCs), with their excellent physical and mechanical properties, such as high specific strength, low density, and high-temperature resistance, hold broad application prospects in aerospace, transportation, energy technology, and other fields. They are also considered by various countries as strategic thermal structural materials for next-generation aircraft engines and a core technology for future engines. Although CMC components can achieve near-net-shape shapes, they still require secondary machining to ensure surface accuracy. Due to their high hardness, brittleness, anisotropy, and heterogeneity, CMCs experience rapid tool wear during machining, leading to a rapid increase in cutting forces. This increased cutting force exacerbates vibration during machining, severely impacting process quality. Therefore, tool wear monitoring is necessary to ensure workpiece quality and avoid material waste.

[0003] At present, most existing tool inspection fixtures at home and abroad are fine-tuned manually. The position accuracy of the tool adjustment is poor, resulting in large measurement errors and limited adjustment freedom. In addition, the adjusted fixture and tool need to be placed under a microscope for inspection, which makes the operation process complicated and has poor versatility. In addition, it cannot guarantee that the tool clamping position remains unchanged before and after disassembly and assembly. Subsequent processing requires re-tooling, which reduces production efficiency. In addition, the existence of radial runout errors of the spindle and tool will affect the processing accuracy of the parts. For example, the pomBasicMicro compact tool inspection equipment produced by the German ZOLLER company is mainly used for measuring information such as cutting edge wear and tool angle. The tool is adjusted manually through the workbench and needs to be used in conjunction with dedicated measuring equipment for measurement. The Rotation-Grip rotary fixture produced by the Austrian company Alicona has two rotational degrees of freedom and is mainly used for cutting edge passivation measurement. It needs to be used in conjunction with the tool inspection profiler produced by the company. Domestic invention patent CN105127924A discloses a "fixture for tool wear detection." This fixture consists of a tool clamping assembly, a bracket assembly, a turntable assembly, and a displacement table assembly. The fixture uses the tool clamping assembly to position and clamp the tool. Manual adjustment of the displacement table achieves small-scale translational motion in the X and Y planes, and manual adjustment of the turntable assembly achieves rotation in the X, Y, and Z axes. Jia Zhenyuan et al. proposed a "fixture for tool cutting edge wear detection," patent publication number CN109946152A, which relates to a fixture for tool cutting edge wear detection. The fixture consists of a base, bracket, indexing plate, gear assembly, clamping assembly, and collet assembly. The bracket, indexing plate, and collet assembly are manually adjusted to the appropriate position corresponding to the scale lines on the fixture, and then tightened using a set screw and knob locking mechanism. Neither of the above two invention patents can achieve adjustment of the tool's six degrees of freedom, making it impossible to measure certain specific wear locations on the tool. Manual adjustment results in large positioning errors, making it difficult to accurately position the tool for testing and inefficient. Tian Ying et al. proposed a "non-contact on-machine end mill side wear morphology detection test bench and method," patent publication number: CN113899311A. The system involves a detection control and implementation module, a three-axis motion controller, a line laser scanning micrometer, an industrial microscope, a side posture adjustment cylinder, an electric rotary platform, an end mill fixture, an optical platform, and a mounting base. The three-axis motion controller controls the movement of the X, Y, and Z-axis arms to adjust the position of the line laser scanning micrometer relative to the milling cutter. The electric rotary platform controls the end mill's rotation around the Z axis to complete milling cutter rotation testing. The end mill side wear data acquired through line laser scanning technology is merged with that acquired through machine vision technology to obtain complete wear status data for the end mill to be tested. However, the device is complex in structure and limited to milling cutter measurement, making it less versatile.

[0004] At present, the main problems in the tool wear detection process are: 1. It is impossible to ensure that the clamping position of the tool before and after removal and installation is consistent, and the tool needs to be re-calibrated, which wastes time and reduces processing efficiency. In addition, due to radial runout error, it will affect the workpiece processing accuracy; 2. The degree of freedom of current detection equipment is difficult to meet the measurement of tools of different types and geometric parameters, and its versatility is poor; 3. Existing tool wear detection equipment mostly uses manual adjustment, with low positioning accuracy, and cannot guarantee the accuracy and repeatability of tool wear detection. Summary of the Invention

[0005] To address the technical challenges outlined above, an integrated device for tool disassembly and wear detection has been proposed. A motor-driven system enables tool disassembly and installation, as well as six-degree-of-freedom tool position adjustment.

The rotation and movement of the tool in six degrees of freedom can be achieved through the rotation of the motor, thereby meeting the wear detection of the tool under different placement angles and positions;

[0018] S3. After the inspection is completed, remove the spring clamp and the tool and place them on the transverse screw slide. Insert a pin into the transverse screw slide to fix the spring clamp. The transverse screw motor rotates and drives the transverse screw slide to move directly under the tool through the transverse screw. The longitudinal screw motor rotates and lowers the longitudinal screw slide to position C. Then use a tool to tighten the three-jaw chuck and loosen the spring clamp knob.

[0019] The longitudinal screw motor rotates to lift the longitudinal screw slide upward to position B, so that the tool is released from the spring clamp. The transverse screw drives the transverse screw slide to move so that the transverse screw slide is misaligned with the longitudinal screw slide.

[0020] The longitudinal screw motor rotates to lower the longitudinal screw slide to position A, insert the end of the tool into the tool holder, tighten the spring collet to fix the tool, remove the tool holder from the tool holder placement table and install it back on the machine tool.

[0021] The beneficial effects of the present invention are: 1.

The tool axis and the three-jaw chuck axis are coaxial. First, insert a tool into the three-jaw chuck tightening hole on the three-jaw chuck. Loosen the three-jaw chuck. The longitudinal screw motor rotates, driving the longitudinal screw slide to position A where the tool is clamped. Then use the tool to tighten the three-jaw chuck to clamp the tool. Then the longitudinal screw motor rotates to lift the longitudinal screw slide upward to position B, so that the bottom end of the tool does not interfere with the spring clamp on the transverse screw slide in the transverse position; The horizontal screw motor rotates and drives the horizontal screw slide to move directly under the tool through the horizontal screw, and loosens the spring clamp knob. The spring clamp axis on the horizontal screw slide is coaxial with the tool axis. The longitudinal screw motor rotates and drives the longitudinal screw slide downward to position C. Insert the end of the tool into the spring clamp, then tighten the spring clamp knob and loosen the three-jaw chuck. The longitudinal screw motor rotates to drive the longitudinal screw slide to move upward to position B, so that the three-jaw chuck is completely separated from the tool. Pull out the pin on the transverse screw slide, remove the spring clamp and tool together, and place them on the magnetic chuck on the tool detection device to engage with them. S2. After the removed spring clamp with the tool is attracted to the magnetic chuck, the rotary table motor rotates to drive the rotary table to rotate around the Z axis, the mobile bracket motor rotates to drive the mobile bracket to move in the X direction relative to the rotary table, the telescopic bracket motor rotates to move the telescopic bracket along the Z axis, the screw motor rotates to drive the screw support seat to move along the Y direction through the slide screw, the chuck rotation motor rotates to drive the magnetic chuck to rotate around the X axis, the chuck shaft rotation motor rotates to drive the magnetic chuck to rotate around the Y axis through the shaft, and the removed spring clamp and tool are attracted to the magnetic chuck. The rotation and movement of the tool in six degrees of freedom can be achieved through the rotation of the motor, thereby meeting the wear detection of the tool under different placement angles and positions; S3. After the inspection is completed, remove the spring clamp and the tool and place them on the transverse screw slide. Insert a pin into the transverse screw slide to fix the spring clamp. The transverse screw motor rotates and drives the transverse screw slide to move directly under the tool through the transverse screw. The longitudinal screw motor rotates and lowers the longitudinal screw slide to position C. Then use a tool to tighten the three-jaw chuck and loosen the spring clamp knob. The longitudinal screw motor rotates to lift the longitudinal screw slide upward to position B, so that the tool is released from the spring clamp. The transverse screw drives the transverse screw slide to move so that the transverse screw slide is misaligned with the longitudinal screw slide. The longitudinal screw motor rotates to lower the longitudinal screw slide to position A, insert the end of the tool into the tool holder, tighten the spring collet to fix the tool, remove the tool holder from the tool holder placement table and install it back on the machine tool.
