Abstract
Description
Technical Field
[0001] This utility model relates to a flip-up fixture for machining both ends of a cylindrical mirror. Background Technology
[0002] The two ends of a cylindrical mirror require grinding and polishing processes. The existing process involves inserting one end (the first end) of the cylindrical mirror into a mold's receiving groove, leaving the other end (the second end) exposed. Wax is then injected into the receiving groove to secure the mirror. After the second end is machined, the mirror is demolded, inverted, and repositioned in the receiving groove for wax injection and fixation. The first end is then machined again. However, this inversion and repositioning process is prone to displacement, affecting machining accuracy and reducing product yield. Furthermore, the secondary wax injection operation is cumbersome and inefficient. Utility Model Content
[0003] The purpose of this utility model is to provide a flip-up fixture for processing the two ends of a cylindrical mirror, including a base and a flip-up seat; the flip-up seat has a receiving cavity extending along its length in the middle; the receiving cavity has a plurality of mounting positions for placing the cylindrical mirror in sequence along its extension direction; the receiving cavity has an upper opening penetrating the upper end of the flip-up seat and a lower opening penetrating the lower end of the flip-up seat; the upper opening and the lower opening are used for the two ends of the cylindrical mirror to extend out of the receiving cavity; the base has a fixing groove, and the flip-up seat can be placed in the fixing groove with the upper opening facing down or the lower opening facing down; the bottom of the fixing groove has a recess for receiving the ends of the cylindrical mirror; a locking mechanism is provided between the flip-up seat and the base for fixing the flip-up seat to the base.
[0004] In this technical solution, when the cylindrical mirror is fixed in the receiving cavity of the flipping seat, its two ends extend out of the receiving cavity. The cylindrical mirror can be rotated synchronously by flipping and inverting the flipping seat, and the two ends of the cylindrical mirror can be processed separately. There is no need to repeatedly disassemble and assemble the cylindrical mirror, which avoids the displacement of the cylindrical mirror and improves the processing accuracy and efficiency.

[0015] Cylindrical mirror 3, first cylinder 31, second cylinder 32. Detailed Implementation
[0016] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:
[0017] See appendix Figure 1-9 A flip-up fixture for machining both ends of a cylindrical mirror 3 includes a base 1 and a flip-up seat 2.
[0018] The cylindrical mirror 3 includes a first cylinder 31 and a second cylinder 32 connected coaxially; the diameter of the first cylinder 31 is smaller than the diameter of the second cylinder 32.
[0019] The flip base 2 has a receiving cavity 21 extending along its length in the middle; the receiving cavity 21 has a plurality of mounting positions for placing cylindrical mirrors 3 in sequence along its extending direction; the receiving cavity 21 has an upper opening 22 penetrating the upper end of the flip base 2 and a lower opening 23 penetrating the lower end of the flip base 2; the upper opening 22 and the lower opening 23 are used to allow the two ends of the cylindrical mirrors 3 to extend out of the receiving cavity 21 for processing.
[0020] In this embodiment, the flip seat 2 has a symmetrical structure.
[0021] The receiving cavity 21 includes two parallel side cavity walls 211; each side cavity wall 211 has an arc-shaped recess 212 corresponding to each mounting position, which fits into the cylindrical mirror 3; the arc-shaped recesses 212 are evenly spaced. The cylindrical mirror 3 is limited by the arc-shaped recesses 212, which improves the stability of the assembly.
[0022] The gap between the cylindrical mirror 3 and the receiving cavity 21 is filled with wax to fix the cylindrical mirror 3 relative to the flipping seat 2.
[0023] The base 1 is provided with a fixing groove 11. The flipping seat 2 can be placed in the fixing groove 11 with the upper opening 22 facing down or the lower opening 23 facing down. That is, the flipping seat 2 can be placed upright or flipped upside down and then placed into the fixing groove 11. The bottom of the fixing groove 11 is provided with a cavity 12 for accommodating the end of the cylindrical mirror 3.
[0024] In this technical solution, when the cylindrical mirror 3 is fixed in the receiving cavity 21 of the flipping seat 2, its two ends extend out of the receiving cavity 21. The cylindrical mirror 3 can be rotated synchronously by flipping and inverting the flipping seat 2, and the two ends of the cylindrical mirror 3 can be processed separately. There is no need to repeatedly disassemble and assemble the cylindrical mirror 3, avoiding displacement of the cylindrical mirror 3 and improving processing accuracy and efficiency.
[0025] A locking mechanism for fixing the flip base 2 to the base 1 is provided between the flip base 2 and the base 1. The locking mechanism includes a screw hole 24 on the flip base 2, a connecting hole 13 on the base 1, and a locking screw 14 connecting the screw hole 24 and the connecting hole 13. Multiple sets of the locking mechanism are provided. In this embodiment, four sets of the locking mechanism are provided, distributed in pairs on both sides of the fixture.
[0026] The screw hole 24 is located on the side of the flip seat 2, and the height difference between the screw hole 24 and the upper end of the flip seat 2 and the lower end of the flip seat 2 is equal; the fixing groove 11 includes two parallel side walls 111, the flip seat 2 is sandwiched between the two side walls 111, and the connecting hole 13 penetrates the side wall 111 of the fixing groove 11; the connecting hole 13 is a U-shaped hole, and when there is a slight deviation in the position of the screw hole 24, the locking screw 14 can be moved up and down along the U-shaped hole to adapt; the screw passes through the connecting hole 13 and is screwed into the screw hole 24.
[0027] When it is necessary to remove the flip base 2, loosen the locking screw 14. It is not necessary to unscrew it completely. The locking screw 14 can be moved out of the base 1 along the upper opening of the U-shaped hole. The U-shaped hole reduces the difficulty of locking and unlocking the locking mechanism and improves efficiency.
[0028] The base 1 has a mounting hole at its bottom for connection and fixation to the workbench. In this embodiment, the mounting hole extends from the cavity 12 to the bottom surface of the base 1. The mounting hole is a countersunk hole 15, which can accommodate the head of the connecting screw and prevent it from being exposed and in contact with the cylindrical mirror 3.
[0029] In practice, it is preferable to set the length of both ends of the cylindrical mirror 3 extending outside the flipping seat 2 to be less than the depth of the cavity 12, so as to avoid the end face of the cylindrical mirror 3 from touching the cavity 12.
[0030] The cavity 12 is lined with a velvet pad or a silicone pad (not shown in the attached figure) to prevent the end of the cylindrical mirror 3 from touching the cavity 12 and being damaged when the positioning is deviated.
[0031] In use, first place the flip base 2 in the positioning mold (not shown in the attached diagram), which is used to help fix the relative positions of the cylindrical mirror 3 and the flip base 2; then place the cylindrical mirrors 3 to be processed one by one into the mounting positions of the receiving cavity 21, that is, arrange them along the extension direction of the receiving cavity 21, with both ends of the cylindrical mirrors 3 extending out of the receiving cavity 21 from the upper opening 22 and the lower opening 23 respectively; then inject wax liquid into the gap between the cylindrical mirrors 3 and the receiving cavity 21 to fix the cylindrical mirrors 3; then transfer the flip base 2 with the cylindrical mirrors 3 loaded to the fixing groove 11 of the base 1, and tighten the locking screw 14, as shown. Figure 3 and Figure 5 As shown, the end of the cylindrical mirror 3 exposed above the flipping base 2 is processed. In this embodiment, one end of the first cylinder 31 is processed first. After processing, the locking screw 14 is loosened, the flipping base 2 is removed, rotated 180 degrees, and then placed into the fixing groove 11 and locked in place. Figure 4 and Figure 6 As shown, the other end of the cylindrical mirror 3 is then processed. In this embodiment, it is shown as one end of the second cylinder 32.
[0032] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
