Abstract
Description
Technical Field
[0001] This application relates to the field of surface shape detection technology, specifically to a glass component clamping device. Background Technology
[0002] When measuring the surface shape of a target product using a laser interferometer, the surface to be measured needs to be parallel to the laser emitting surface. In practical applications, the laser emitting surface of the laser interferometer is usually parallel to a vertical plane, and its large size makes it difficult to change. When inspecting a target product, the fixtures provided with the laser interferometer are insufficient to fix the surface to be measured parallel to the laser emitting surface, especially for ultra-precision components such as optical elements (e.g., microcrystalline glass), where most of their surfaces cannot directly contact other parts, thus making surface shape data acquisition impossible. Furthermore, if the center of gravity is unstable after clamping the target product, it can cause deformation and tilting, directly affecting the accuracy of the surface shape measurement. Therefore, before using a laser interferometer to inspect the surface shape of a target product, an auxiliary fixture needs to be designed to fix the target product and ensure that its surface meets the inspection requirements. Utility Model Content
[0003] The purpose of this application embodiment is to provide a glass component clamping device for reliably fixing the target product to be tested, so that the test surface of the target product meets the detection requirements of the laser interferometer, while avoiding deformation and tilting of the fixed target product.
[0004] To achieve the above objectives, this application provides a glass element clamping device, which includes a frame, an adjusting member, a support plate, and a fixing member. The frame is adapted to a target microcrystal and is used to fix the target microcrystal. The adjusting member is connected to the frame and abuts against the target microcrystal, and is used to fine-tune the position of the target microcrystal in the frame and to fix the target microcrystal. One edge of the frame is fixedly connected to the support plate through the fixing member, and this edge is a load-bearing edge. The frame surface of the frame is perpendicular to the plate surface of the support plate.
[0005] In this embodiment, the frame includes a main frame and a sub-frame; the sub-frame is disposed on one side of the main frame and fixedly connected to the main frame, and the frame surface of the sub-frame is parallel to the frame surface of the main frame; the adjusting member is connected to the main frame; the main frame is fixedly connected to the support plate through a fixing member; the inner cavity size of the sub-frame is smaller than the outer edge size of the target microcrystal, and the outer edge size of the target microcrystal is smaller than the inner cavity size of the main frame.
[0006] In this embodiment, the adjusting member includes a set screw, the main frame and the sub-frame are both rectangular, the main frame includes a load-bearing frame side and other frame sides, the load-bearing frame side is fixedly connected to the support plate by a fixing member, and the other frame sides of the main frame are respectively provided with a plurality of screw holes adapted to the set screw; the set screw can pass through the screw holes and abut against the side wall of the target microcrystal.
[0007] In this embodiment of the application, each side of the main frame is provided with a dispensing hole, and the axis of the dispensing hole is parallel to the axis of the screw hole.
[0008] In this embodiment of the application, each edge of the sub-frame is provided with a dispensing hole, and the axis of the dispensing hole is perpendicular to the frame surface of the sub-frame.
[0009] In this embodiment, the glass element clamping device further includes a flexible protective pad, and the inner sidewall of the load-bearing frame is provided with a groove adapted to the flexible protective pad.
[0010] In this embodiment, the flexible protective pad is made of nylon.
[0011] The solution provided in this application has at least the following beneficial effects: The glass component clamping device provided in this application uses a frame adapted to the shape of the target microcrystal to fix the target microcrystal. Through the connection between the support plate and the frame, the measured surface of the target microcrystal can be aligned with the laser emitting surface of the laser interferometer, meeting the testing requirements. Furthermore, the position of the target microcrystal within the frame can be precisely adjusted and reliably fixed by the set screws on each frame edge. The dispensing holes on each frame edge allow for subsequent dispensing and fixing of the target microcrystal, further improving the reliability of the frame in fixing the target microcrystal. The flexible protective pad embedded in the load-bearing frame edge provides protection for the target microcrystal when the frame is placed vertically, preventing direct contact between the target microcrystal and the load-bearing frame edge, reducing the risk of breakage.

Example
[0018] like Figure 1 As shown, this embodiment provides a glass element clamping device, which includes a frame 1, an adjusting member 2, a support plate 3, and a fixing member. The frame 1 is adapted to the target microcrystal 100 and is used to fix the target microcrystal 100. The adjusting member 2 is connected to the frame 1 and abuts against the target microcrystal 100, and is used to fine-tune the position of the target microcrystal 100 in the frame 1 and to fix the target microcrystal 100. One of the frame edges of the frame 1 is fixedly connected to the support plate 3 through the fixing member. The frame surface of the frame 1 is perpendicular to the plate surface of the support plate 3.
[0019] Specifically, such as Figure 2 and 3 As shown, the frame 1 includes a main frame 11 and a sub-frame 12; the sub-frame 12 is disposed on one side of the main frame 11, the frame surface of the sub-frame 12 is parallel to the frame surface of the main frame 11, the sub-frame 12 is fixedly connected to the main frame 11, the inner cavity size of the sub-frame 12 is smaller than the outer edge size of the target microcrystal 100, and the outer edge size of the target microcrystal 100 is smaller than the inner cavity size of the main frame 11. For example, if the frame 1 is rectangular (fitting the rectangular target microcrystal 100), the adjusting member 2 includes several set screws (nylon rubber-tipped set screws), the main frame 11 includes a load-bearing frame edge and other frame edges besides the load-bearing frame edge, the load-bearing frame edge is fixedly connected to the support plate 3 by fasteners (screws, bolts, etc.), and the other frame edges of the frame 1 are respectively provided with multiple screw holes adapted to the set screws; these set screws can pass through the screw holes and abut against the side wall of the target microcrystal 100 (i.e., the hole axis direction of the screw hole is parallel to the frame surface of the frame 1), these set screws can realize the adjustment and fixation of the position of the target microcrystal 100. Figure 1 and 2As shown, since the inner cavity size of the sub-frame 12 is smaller than the outer edge size of the target microcrystal 100, the target microcrystal 100 can only be inserted from one side of the main frame 11 when it is embedded. In order to avoid the angle error between the measured surface of the target microcrystal 100 and the frame surface of the main frame 11, when installing the target microcrystal 100, the frame 1 must first be placed horizontally with one side of the sub-frame 12 facing down, and then the target microcrystal 100 is inserted from the other side of the main frame 11 away from the sub-frame 12. Due to the influence of gravity, the four edges of the target microcrystal 100 are always in contact with the frame edge of the sub-frame 12, and the upper surface (i.e. the measured surface) of the target microcrystal 100 is always parallel to the frame surface of the main frame 11. Several set screws are connected to the other three frame edges (excluding the load-bearing frame edge), allowing force to be applied to the target microcrystal 100 from three directions to adjust its position. Adjusting the target microcrystal 100 by having it abut against the load-bearing frame edge improves adjustment efficiency; only two directions (through the set screws on the two adjacent frame edges of the load-bearing frame) are needed to adjust its position. After the adjusting component 2 has completed the position adjustment and fixed the target microcrystal 100, the target microcrystal 100 and the mirror frame 1 are rotated, fixing the load-bearing frame edge at the bottom of the main frame 11 to the support plate 3. This ensures that the frame surface of the mirror frame 1 (the measured surface of the target microcrystal 100) is parallel to the vertical direction and faces the detection surface of the laser interferometer. Furthermore, to improve the reliability of the connection between the mirror frame 1 and the target microcrystal 100, the other frame edges of the mirror frame 1 (main frame 11) are also provided with dispensing holes 5, the axis of which is parallel to the axis of the screw hole. Additionally, dispensing holes 5 can be provided on the four edges of the sub-frame 12, with the axis of the dispensing holes 5 perpendicular to the frame surface of the sub-frame 12 (the measured surface of the target microcrystal 100). After the target microcrystal 100 is fixed in place by the set screws, glue is dispensed through the dispensing holes 5. Then, wait for the glue to solidify, and finally rotate the target microcrystal 100 and the frame 1 to fix the load-bearing frame edge at the bottom of the frame 1 to the support plate 3 (using screws, bolts, etc.).
[0020] The presence of the sub-frame 12 helps to improve the stability of the connection between the target microcrystal 100 and the frame 1. At the same time, the sub-frame 12 will not have large-area direct contact with the target microcrystal 100, reducing the possibility of relative friction between the target microcrystal 100 and the sub-frame 12, thus ensuring the quality of the target microcrystal 100.
[0021] Preferably, the glass element clamping device further includes a flexible protective pad 4, and the inner sidewall of the load-bearing frame is provided with a groove adapted to the flexible protective pad 4. When the target microcrystal 100 is placed vertically, the load-bearing frame needs to bear the entire weight of the target microcrystal 100. To avoid damage to the target microcrystal 100, such as Figure 2In this embodiment, a flexible protective pad 4 is embedded on the inner side of the load-bearing frame edge, and the top of the flexible protective pad 4 is slightly higher than the surface of the load-bearing frame edge. If there are multiple grooves (more than two), the multiple grooves are evenly distributed along the length direction of the load-bearing frame edge to ensure that each flexible protective pad 4 is subjected to uniform force so that the target microcrystal 100 does not tilt. For example, the flexible protective pad 4 is made of nylon material, which has advantages such as high strength, high toughness, easy processing and molding, and high cost performance.
