The requirements for the machining accuracy of ultra-high precision planes are gradually increasing.

[0003] During the production of ultra-high precision flat surfaces, most only an upper pressing component is used to clamp the high precision flat surface. However, since most high precision flat surface workpieces have irregular shapes and varying thicknesses, clamping them only with the upper pressing component will cause the high precision flat surface workpiece to vibrate, thereby affecting the surface finish and precision of the machined surface and impacting product quality.

[0038] like Figures 1-5 As shown, this embodiment provides a module for ultra-high precision planar production, including a base 10. A frame 60 is fixedly installed on the base 10 by means of fastening bolts or the like. A first rotary motor 501 is fixedly installed on the frame 60. The drive end of the first rotary motor 501 passes through the frame 60 and is connected to a first lead screw 502 through a bearing assembly. A first lead screw nut 503 is installed on the first lead screw 502, and the lead screw and lead screw nut 503 form a helical drive. A second rotary motor 505 is fixedly installed on a connecting bracket set on the first lead screw nut 503 by fastening screws. The drive shaft of the second rotary motor 505 is connected to a second lead screw 504 through a bearing assembly. A second lead screw nut is installed on the second lead screw 504, and a grinding mechanism 506 is installed on the second lead screw nut. The grinding mechanism 506 is preferably a high-precision grinding machine.

[0039] In this embodiment, by starting the first rotary motor 501, the first lead screw is driven to rotate, causing the first lead screw nut disposed on the first lead screw to move linearly along the lateral direction of the first lead screw; similarly, by starting the second rotary motor 505, the second lead screw 504 is driven to rotate, causing the second lead screw nut 507 disposed on the second lead screw 504 to adjust its position along the longitudinal direction of the second lead screw 504.

[0040] Furthermore, the bottom end of the second lead screw nut 507 located away from the grinding mechanism 506 is fixedly mounted with a pressing cylinder 701 of the pressing mechanism 70 by fastening screws, and the extended end of the pressing cylinder 701 is fixedly mounted with a mounting plate 702. At least two sets of pressing seats 703 are provided on the end face of the mounting plate 702 away from the pressing cylinder 701.

[0041] In this embodiment, at least two sets of lifting and lowering pressing seats 703 press the surface of the high-precision plane, thereby ensuring that the workpiece remains relatively stable during processing and reducing unnecessary stress concentration.

[0042] Furthermore, at least two sets of transverse modules 20 are provided on the base 10, and the transverse module 20 is preferably a lead screw drive assembly. A worktable 40 is fixedly installed on the moving seat of the transverse module 20 by fastening screws, and at least two sets of auxiliary clamping assemblies are provided on the worktable 40.

[0043] In this embodiment, a pressing mechanism presses the high-precision plane, while two sets of auxiliary clamping components clamp the protruding ends of the high-precision plane, thereby preventing vibration of the high-precision flat workpiece, improving the surface finish and precision of the processed surface, and improving product quality.

[0044] Please accept this. Figure 3 and Figure 4 As shown, the auxiliary clamping assembly 30 includes a hydraulic cylinder 301, preferably 8040300-8MPA. The extended end of the hydraulic cylinder 301 is fixedly mounted with a clamping plate 302 by fastening screws, and the clamping plate 302 has a clamping groove 303 inside, and the clamping groove 303 is not a through groove.

[0045] Furthermore, an auxiliary block 306 is provided on the inner wall of the clamping groove 303, and a spring 304 is fixedly installed between the auxiliary block 306 and the inner wall of the clamping groove 303. A non-penetrating rectangular groove is formed on the end face of the auxiliary block 306 away from the spring 304 for accommodating the workpiece, and the non-penetrating rectangular groove is in close contact with the outer wall of the workpiece. This is used to clamp the workpiece, and at the same time, in order to further improve the stability of clamping, the inner wall of the non-penetrating rectangular groove is wrapped with an elastic pad.

[0046] Furthermore, at least one set of positioning members 305 are provided on the bottom end face of the clamping groove 303, and the positioning member 305 is provided with a positioning groove 3051 for the auxiliary block 306 to extend into, and is engaged and connected.

[0047] Furthermore, the auxiliary block 306 is arranged in an L-shape.

[0048] Furthermore, the auxiliary block 306 has a height of 13-16mm; the positioning groove has a height of 16mm-17.5mm.

[0049] Furthermore, the outer wall of the auxiliary block 306 is provided with a protrusion that engages with a slot formed on the inner wall of the positioning groove 3051.

[0050] In this embodiment, when the workpiece is inserted into the clamping groove 303, the pushing force will push the workpiece toward the spring 304, causing the spring 304 to undergo elastic deformation until the protrusion on the auxiliary block 306 is engaged in the slot for locking connection.

[0051] When the spring is uncompressed, one end of the auxiliary block extends into the positioning groove, and the protrusion of the auxiliary block in the positioning groove does not engage with the slot. As the spring is continuously compressed, the auxiliary block moves towards the spring position under the push until the protrusion automatically engages with the slot, thus completing the engagement connection.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
