Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and in particular relates to a splicing block for positioning and supporting workpieces during the processing of optical components. Background Technology

[0002] The demands for processing quality and efficiency of precision optical components are increasing across various fields, especially for large-aperture optical components required in advanced optical systems such as astronomical telescopes, extreme ultraviolet lithography machines, and high-power laser devices. Against this backdrop, various sub-aperture polishing technologies based on the principle of Computer-Controlled Optical Surface Forming (CCOS) have been significantly developed, such as small-tool CNC polishing, airbag polishing, and magnetorheological polishing. In the CCOS process, workpieces of different shapes need to be polished. To ensure the accurate positioning and stability of the workpiece during processing and to prevent damage, displacement, or deformation, stops are often used to position and support the workpiece, meeting the processing requirements of different workpieces. Currently, the stops used in polishing machine tools are typically of inflexible structures, difficult to adjust to accommodate workpieces of other sizes once installed. Therefore, when processing workpieces of different shapes and sizes, the stops need to be frequently changed to ensure accurate positioning and stability during processing. This not only increases additional costs but also leads to material waste and environmental pollution. Utility Model Content

[0003] In view of this, the present invention aims to provide a modular stop block to solve the problems of poor flexibility and material waste in existing stop blocks. This modular stop block can be connected and adjusted according to the shape and size of different workpieces to meet the processing requirements of different workpieces, thereby improving processing efficiency and quality.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A modular stop block includes multiple stop block units and a connecting mechanism. The connecting mechanism is used to assemble the stop block units into various three-dimensional shapes; each stop block unit is a rectangular plate, with splicing slots on three sides and a square groove on the other side; the connecting mechanism includes a positioning pin and / or a positioning key, the positioning pin being used to connect the splicing slots of adjacent stop block units, and the positioning key being used to connect the square grooves of adjacent stop block units.

[0006] Furthermore, the inner width of the splicing groove is greater than the outer width, and the two edges on the inner side of the splicing groove are rounded.

[0007] Furthermore, the positioning pin is a rectangular block that is narrow in the middle and wide on both sides, and the four edges of the rectangular block are rounded. The positioning pin is inserted into the splicing groove to realize the parallel connection and / or superimposed connection between adjacent stop block units.

[0008] Furthermore, the positioning key is a square plate, and the positioning key is inserted into the square groove to achieve vertical connection and / or superimposed connection between adjacent stop block units.

[0009] Furthermore, the stop unit and the connecting mechanism are connected by an interference fit.

[0010] Furthermore, a through hole is formed at the center of the upper surface of the stop block unit, the through hole extending from the upper surface to the lower surface, the through hole being used to fix the stop block unit.

[0011] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 4As shown, this embodiment provides a modular stop block 1, including multiple identical stop block units (including but not limited to stop block units 11, 12, 13, 14, and 15) and a connecting mechanism. The connecting mechanism is used to assemble the stop block units into various three-dimensional shapes.

[0027] In this embodiment, the stop unit is a rectangular plate. Three sides of the rectangular plate are respectively provided with splicing grooves, and the other side is provided with a square groove. The connecting mechanism includes a positioning pin 2 and / or a positioning key 3. The positioning pin 2 is used to connect the splicing groove of the adjacent stop unit, and the positioning key 3 is used to connect the square groove of the adjacent stop unit.

[0028] Specifically, in this embodiment, the inner width of the splicing groove is greater than the outer width, and the two edges on the inner side of the splicing groove are rounded to ensure smooth assembly and stable connection, thus preventing detachment. More specifically, the depth of the splicing groove is L, and a radius of [missing information] is formed at the two edges on the inner side of the splicing groove. The rounded corners have a central angle of 120° corresponding to the arc of the rounded corner, and Let be the distance from the side of the stop block unit to the outer point of the fillet within the splicing groove, satisfying: That is, the inner width of the splicing groove is wider than the outer width. .

[0029] Specifically, in this embodiment, the positioning pin 2 is a rectangular block that is narrow in the middle and wide on both sides. The four edges of the rectangular block are rounded, and its shape matches the splicing groove. The positioning pin 2 is inserted into the splicing groove to achieve parallel connection and / or superimposed connection between adjacent stop block units. Since the inner width of the splicing groove is greater than the outer width, the positioning pin 2 can be firmly fixed in the splicing groove, ensuring that the connection between the stop block units is stable and reliable. More specifically, when the stop block units are connected in a plane, the splicing grooves of the two arbitrary stop block units 11 and 12 are aligned with each other, and the positioning pin 2 is hammered into the hole formed by the stop block units 11 and 12. This interference fit connection method of the stop block units 11 and 12 can achieve no relative displacement between the connected stop block units 11 and 12. The same method can be used to connect adjacent stop block units in parallel according to actual needs. Here, it can be understood that the number of stop block units is not limited. When the block units are stacked, block unit 13 and block unit 14 are aligned and stacked so that their splicing grooves and square grooves correspond respectively. When splicing, the positioning pin 2 is used to stack and connect block unit 13 and block unit 14. The same method can be used to stack and connect the stacked block units according to actual needs. Here it can be understood that there is no limit to the number of block units.

[0030] Specifically, in this embodiment, the positioning key 3 is a square plate whose shape matches the square groove. The positioning key 3 is inserted into the square groove to achieve vertical connection and / or overlapping connection between adjacent stop block units. The square design of the positioning key 3 fits tightly with the square groove, ensuring a stable and reliable connection between the stop block units. More specifically, when the stop block units are vertically connected, the square grooves of stop block units 13 and 15 are aligned and placed vertically. The positioning key 3 is driven into the hole formed by stop block units 13 and 15. This interference fit connection method between stop block units 13 and 15 ensures that there is no relative displacement between the connected stop block units 13 and 15. The same method can be used to vertically connect adjacent stop block units according to actual needs. This can be understood as not limiting the number of stop block units. When stacking and connecting the stop block units, stop block units 13 and 14 are aligned and stacked so that their splicing grooves and square recesses correspond respectively. During splicing, positioning keys 3 are used to stack and connect stop block units 13 and 14. The same method can be used to stack and connect the stacked stop block units according to actual needs. Here, it can be understood that there is no limit to the number of stop block units. When the height of the workpiece 4 that needs to be fixed is relatively high, stop block units 13 and / or stop block units 14 need to be vertically connected to stop block unit 15. As the height of workpiece 4 increases, stop block units can be added arbitrarily above stop block units 13 and / or stop block units 14. When the height of workpiece 4 is relatively low, the vertically connected stop block units 13 and 14 are not required. Positioning can be achieved by combining stop block units on the same plane as stop block unit 15 or by stacking them on the upper plane of stop block unit 15.

[0031] like Figure 4 As shown, in this embodiment, when using the splicing blocks to position the workpiece 4 on the mounting platform, bolts and / or screws are used to fix the last row of block units furthest from the workpiece 4 to the mounting platform, thereby achieving the effect of positioning and supporting the workpiece 4 using the splicing block units. More specifically, bolts and / or screws corresponding to the splicing slots are inserted into the splicing slots on both sides of the last row of block units furthest from the workpiece 4 for fixing. Alternatively, a through hole can be opened at the center of the upper surface of the block unit, extending from the upper surface to the lower surface. The through hole cooperates with the bolts and / or screws to position and support the workpiece 4, preventing the workpiece 4 from shifting relative to the mounting platform during processing and affecting the processing effect.

[0032] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
