The table 11 is used for carrying a processing object or a workpiece 10 to be processed. Generally, the working table 11 may further be provided with a clamping mechanism, a limiting mechanism, a bearing mechanism, and the like.
The primary positioning device 12 is used for positioning the workpiece 10 to be machined within a first accuracy range. Typically for feedback of the approximate position of the workpiece 10 to be machined.
The secondary positioning device 13 is used for positioning the workpiece 10 to be machined within a secondary accuracy range. Typically for feedback of the exact position of the workpiece 10 to be machined.
In the embodiment provided by the present application, the secondary positioning device 13 can rapidly achieve position feedback of the workpiece 10 to be processed within the range defined by the primary positioning device 12, so as to improve positioning efficiency and further improve production and processing efficiency.
The primary positioning device 12 and the secondary positioning device 13 can establish a first galileo coordinate system of the workpiece 10 to be processed. And a second galileo coordinate system is set in the machining program of the workpiece 10 to be machined. The first galileo coordinate system of the workpiece 10 to be machined and the second galileo coordinate system set in the machining program are subjected to coordinate transformation, that is, the relative position in the machining program is transformed into the absolute position of the workpiece 10 to be machined, thereby facilitating the production machining.

Such as turning tool systems, milling cutter systems, planing tool systems, and the like. The machining tool may also include a tool accessory 14 for clamping the secondary positioning device 13.

Fig. 3 is an exploded view of the precision inspection apparatus. A precision inspection apparatus comprising:
the measuring rod 131 is used for detecting the micro distance between the measuring rod and an object to be measured in a touch mode;
a tactile feedback component 132 for feeding back the fine pitch information;
the resetting component 133 is used for resetting the measuring rod 131 when the measuring rod 131 and an object to be measured are in a non-contact state;
wherein the reset assembly 133 comprises at least two magnets.
And the measuring rod 131 is used for detecting the micro distance between the measuring rod and the object to be measured in a touch mode. The end of the stylus 131, commonly referred to as the stylus, may be generally made of a relatively hard material, such as ruby or the like. Synthetic ruby may be used here based on cost considerations.
And a tactile feedback component 132 for feeding back the fine pitch information. In a preferred embodiment provided herein, the tactile feedback assembly 132 includes an electrically conductive sphere 1321 and an electrically conductive rod 1322 engaged with the electrically conductive sphere 1321. The conducting rod 1322 is linked with the measuring rod 131. The conductive rods 1322 are distributed between a pair of the conductive balls 1321. When the measuring rod 131 deflects due to touching the object to be measured, a gap is generated between the conductive rod 1322 and the conductive sphere 1321 to generate an open-circuit signal, so that the micro-distance between the measuring rod 131 and the object to be measured is represented to be zero. The conductive rod 1322 may be generally cylindrical, and the conductive ball 1321 may be generally spherical, so that the contact area between the conductive ball 1321 and the conductive rod 1322 is small, and thus the sensitivity is high and the conductive rod 1322 is not easily worn.
In a preferred embodiment provided herein, the electrically conductive rods 1322 are distributed between a pair of the electrically conductive spheres 1321 to form a set of tactile feedback units; the tactile feedback units comprise three groups; the tactile feedback units are uniformly distributed on the circumference at equal intervals. Therefore, the measuring rod 131 can detect the micro-distance between the measuring rod and the object to be measured within the range of 360 degrees of the circumference, and the sensitivity is high.
In a preferred embodiment provided by the present application, the conducting rod 1322 and the measuring rod 131 are linked by:
the tactile feedback assembly 132 includes a mounting portion 1323 for engaging the spindle 131;
the mounting portion 1323 is inserted into the conductive rod 1322.
The resetting component 133 is used for resetting the measuring rod 131 when the measuring rod 131 and an object to be measured are in a non-contact state; the reset assembly 133 includes at least two magnets.

the base 130 is linked with one magnet 1301 of at least two magnets;
the spindle 131 is coupled to another magnet 1301 of the at least two magnets 1301.
Thus, when the measuring rod 131 is in contact with the object to be measured, the measuring rod 131 is forced to deflect relative to the base 130; when the measuring rod 131 and the object to be measured are in a non-contact state, the measuring rod 131 is subjected to the elimination of the deflection force of the object to be measured, and the measuring rod 131 is reset to the balance position under the action of the magnetic force. It can be understood that the base 130 is linked with one magnet 1301 of the at least two magnets 1301, and the measuring bar 131 is linked with the other magnet 1301 of the at least two magnets 1301, so that the measuring bar 131 can be reset to the equilibrium position under the action of the magnetic force when the deflection force of the object to be measured on the measuring bar 131 is eliminated.

In a preferred embodiment provided herein, the precision detection apparatus further comprises a containment vessel;

the conductive slot 2322 is linked with the measuring rod 231.
