Specifically, as shown in fig. 1 to 4, the jig 2 is provided with a plurality of mounting holes 22, and a plurality of the mounting holes 22 are arranged at the periphery of the product accommodating chamber 21; the detecting device 3 is configured to detect the height of the product surface in the product accommodating cavity 21 corresponding to the direction of each mounting hole 22, and transmit corresponding data to the control device 4; after receiving the corresponding height data, the control device 4 may acquire the inclination of the entire surface of the product, i.e. which position on the surface of the product is high or which position is low, so as to acquire the value that should be adjusted high or low at the corresponding position of the fixture 2.
The adjusting device 5 is arranged on the base body 1, and a part of the adjusting device extends into the mounting hole 22 so as to be connected with the clamp 2; in this way, when the adjusting device 5 moves under the control of the control device 4, the fixture 2 can move synchronously, so that the surface inclination of the fixture 2 is adjusted by adjusting the height of the fixture 2 corresponding to the position of each mounting hole 22, and finally the surface inclination of the product in the product accommodating cavity 21 is adjusted.
According to the application, the detection device 3 and the control device 4 are matched, so that the surface gradient of the product assembled in the product accommodating cavity 21 can be obtained, the adjusting device 5 is adjusted according to the surface gradient of the product, the surface gradient of the clamp 2 is adjusted, and the surface gradient of the product is adjusted by means of the surface gradient adjustment of the clamp 2. The whole detection and adjustment process is realized intelligently by the detection device 3, the adjustment device 5 and the control device 4 without manual participation, so that the detection and adjustment precision is improved, the purpose of improving the precision of the micro-nano machining clamp for adjusting and positioning the surface gradient of a product is achieved, and the machining efficiency of the product is improved.
It should be noted that, when the product is assembled in the product accommodating cavity 21, the product may be tightly attached to the fixture 2, so as to ensure that when the adjusting device 5 adjusts the inclination of the fixture 2, the inclination of the surface of the product may be adjusted in a common manner. The movement of the clamp 2 relative to the base 1 is in a micro range, and when the adjusting device adjusts the clamp 2, the movement amplitude generated by the clamp 2 is in millimeter level or even submicron level, so that large-scale and large-range adjustment is not needed.
In an embodiment of the present application, the plurality of mounting holes 22 are arranged in a common circle, and a center of the circle surrounded by the plurality of mounting holes 22 is located on a central axis of the product accommodating cavity 21.
In this embodiment, based on the central axis of the product accommodating cavity 21, the plurality of mounting holes 22 are arranged in a co-circle manner, so that when the adjusting device 5 is started and actively adjusts the clamp 2, the adjusted position on the clamp 2 is arranged around the product and forms a concentric circle with the product accommodating cavity 21, thereby achieving the uniformity of adjustment of the surface inclination of the product when the inclination of the clamp 2 is adjusted, and further improving the accuracy and efficiency of intelligent adjustment of the surface inclination of the product by the micro-nano machining clamp with the automatically adjustable height.
In one embodiment of the present application, the detecting device 3 includes a plurality of infrared distance detectors; the infrared distance detector is used for detecting the heights of test points on the surface of the product, and the test points are in one-to-one correspondence with the mounting holes 22.
In this embodiment, the number of the test points on the surface of the product is equal to the number of the mounting holes 22, and the test points are in one-to-one correspondence with the mounting holes 22; that is, the mounting holes 22 represent adjusting points of the fixture 2, and the number of the adjusting points is equal to that of the test points and corresponds to that of the test points one by one, so that when the adjusting device 5 adjusts the height of the adjusting points under the control of the control device 4, the height of the product corresponding to the position of the mounting holes 22 can be adjusted synchronously.
In an implementation manner of this embodiment, the test point is located on a line between the mounting hole 22 and the circular center of the circle, so that when the inclination of the fixture 2 is further improved, the consistency of synchronous adjustment of the inclination of the product surface is further improved, and therefore the accuracy and efficiency of intelligent adjustment of the inclination of the product surface by the micro-nano machining fixture with the automatically adjustable height are further improved.
Since three points can determine a plane, i.e. when selecting the test point, typically three points can adjust the inclination of a plane to the target inclination. In order to improve the accuracy of the surface inclination adjustment of the product, in one embodiment of the present application, the number of the test points is 6, and the number of the mounting holes 22 is 6; the 6 mounting holes 22 are in the same circle and are uniformly distributed, namely, every two adjacent mounting holes 22 are distributed by 60 degrees of center angle; the 6 test points are in common circles and are uniformly distributed, namely, each two adjacent test points are also distributed by 60 degrees of center angle, and each test point is provided with one mounting hole 22 corresponding to each other.
It should be noted that the micro-nano processing clamp capable of automatically adjusting the height is more suitable for block products or sheet products; the test points are positioned on the surface of the product and are close to the outer edge of the product, namely: the test points need to be within the surface area of the product but as close as possible to the shape edge of the product so that the distance between the test points and the mounting holes 22 is sufficiently close to further promote the synchronicity of adjusting the surface inclination of the product by adjusting the surface inclination of the fixture 2.
In an embodiment of the present application, after the infrared distance detector detects the heights of the corresponding test points, the control device 4 may obtain the actual heights of the 6 test points, so as to calculate and obtain the intermediate heights (average heights) of the 6 test points; for the fixture 2, the distances of 6 adjusting devices 5 in 6 directions are: and if the actual height of the test point is different from the middle height, the control device 4 controls the corresponding adjusting device 5 to correspondingly adjust the height or lower the corresponding position on the clamp 2 according to the difference, so that 6 test points are positioned at the same height, and when the micro-nano machining clamp capable of automatically adjusting the height is assembled on a machine tool, the surface of a product can be perpendicular to a cutter.
