Embodiment Construction

[0014] The specific embodiment of the present invention will be described in detail in conjunction with the accompanying drawings.

[0015] A precision fine-tuning device for the integration of on-machine measurement functions, its working principle: a long hole 1 is processed on the base 1 a , the T-bolt installed in the T-slot of the machine table passes through the long hole 1 a Fix the base 1 and the machine table with the hex nut 35; slide the X-direction sliding seat 4 on the X-direction sliding guide rail 3 to a suitable position, and the rough adjustment of the sensor measuring head 11 in the X direction can be completed. After the rough adjustment is completed, turn the X direction fine adjustment screw 2 to realize the fine adjustment of the sensor probe 11 in the X direction. After the adjustment is completed, use the set bolt 20 to cooperate with the T-shaped slot cThe tightening T-nut 30 in the middle completes locking. In the same way, the Y-direction sliding s...

Abstract

The invention relates to a precision fine-tuning device oriented to the integration of on-machine measurement functions, belonging to the technical field of detection, and relates to a precision fine-tuning device oriented to the integration of on-machine measurement functions. The precision fine-tuning device is composed of a base, a base, an X-direction sliding guide rail assembly, a Y-direction sliding guide rail assembly, a three-point positioning mechanism and a pitch adjustment mechanism. In this device, the X and Y directions of the sensor measuring head are roughly adjusted first, and then fine-tuned by the fine-tuning mechanism. The pitch adjustment mechanism adopts the form of the screw nut to drive the arc matching surface to realize the precise pitch adjustment of the fine-tuning device. The device has a large adjustment range, high rigidity, and compact structure, and realizes the precise adjustment of the three degrees of freedom of the sensor head, and the displacement resolution can reach the micron level. Fast adjustment, high precision and good rigidity. At the same time, the detachable method avoids the measurement device from interfering with the processing process, and at the same time reduces the possibility of damage to the sensor probe, which is highly practical.

Description

technical field [0001] The invention belongs to the technical field of detection and relates to a precision fine-tuning device for on-machine measurement function integration. Background technique [0002] The on-machine measurement takes the CNC machine tool as the carrier, and the measurement of the geometric characteristics of the part can be realized on the machine tool with the corresponding measurement sensor. In particular, for multi-axis linkage ultra-precision turning machine tools, the integration of on-machine measurement functions has become the basic guarantee for the contour of complex ultra-precision parts, such as on-machine trigger measurement, on-machine scanning measurement and so on. What needs to be paid attention to is whether the probe can complete the precise on-machine measurement task of the surface contour of the workpiece, and it is necessary to accurately ensure the spatial pose relationship between the sensor and the machine tool. The key lies i...
