A prism grinding device including a worktable, a grinding mechanism, and an adjustment mechanism was designed. The prism can be quickly adjusted in position by a rotating component and a support assembly. The rotating component rotates around the axis between two positions and abuts against the limiting surface respectively. The support assembly is used to fix the rotating component in different positions. Combined with a cylinder and bolts, the prism can be stably clamped and its position adjusted.
It enables rapid adjustment of the prism position, allowing for convenient grinding of both surfaces. The operation is simple and flexible, improving grinding efficiency and reducing operation steps and time.

[0023] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0024] As attached Figure 1 The prism grinding device of this utility model is shown, including a worktable 1. A grinding mechanism and an adjustment mechanism are installed on the worktable 1. The grinding mechanism includes a movable seat 2 connected to the worktable 1. A motor 3 is installed on the side of the movable seat 2 near the adjustment mechanism. A grinding wheel 4 is installed at the output end of the motor 3 for grinding a prism 30. The adjustment mechanism includes a fixing member 5, a rotating member 6, a first support assembly 7, and a second support assembly 8. The fixing member 5 is connected to the worktable 1. The rotating member 6 is used to clamp the prism 30. The fixing member 5 has a first limiting surface 51 and a second limiting surface 52. Support sidewalls 9 are installed on both sides of the fixing member 5. Rotating holes are machined on the support sidewalls 9. The rotating member 6 has a rotating shaft that is inserted into the rotating hole. (See attached diagram) Figure 3 Appendix Figure 4 As shown, the rotating member 6 includes spaced-apart side plates 63 and a first support plate 61 and a second support plate 62 connecting the two side plates 63. The first support plate 61 and the second support plate 62 form an angle. The rotating member 6 rotates about a pivot axis between a first position and a second position. When in the first position, as shown in the attached diagram... Figure 1 As shown, the first support plate 61 and the first limiting surface 51 abut against each other, and one side of the prism 30 is close to the grinding wheel 4. When in the second position, as shown in the attached figure... Figure 2 As shown, the second support plate 62 abuts against the second limiting surface 52, and the other side of the prism 30 is close to the grinding wheel 4. The first support assembly 7 is used to hold the rotating member 6 in the first position, and the second support assembly 8 is used to hold the rotating member 6 in the second position.
[0025] The movable base 2 includes a horizontally mounted first cylinder 21 and a vertically mounted second cylinder 22. The cylinder body of the first cylinder 21 is fixedly connected to the worktable 1. The output end of the first cylinder 21 is connected to the cylinder body of the second cylinder 22. The output end of the second cylinder 22 is connected to the motor 3, which facilitates the movement of the motor 3 in both horizontal and vertical directions to adjust the grinding wheel 4 to the most suitable grinding position. It can adapt to prisms 30 of different sizes and in different positions.
[0026] As attached Figure 5As shown, the first support assembly 7 includes a first base 71 and a first bolt 72. The top of the first base 71 is machined with a downward-facing threaded hole, and the first bolt 72 is screwed into the threaded hole. A pad 73 is installed on the head of the first bolt 72. A bottom groove 11 adapted to the first base 71 is machined on the worktable 1. The bottom groove 11 is located below the rotating part 6. When the rotating part 6 is in the first position, the first base 71 can be inserted into the bottom groove 11. The first bolt 72 is rotated and adjusted to the length that makes the pad 73 abut against the second support plate 62, thus lifting and fixing the rotating part 6 for easy grinding. The presence of the bottom groove 11 enables the first support assembly 7 to achieve quick positioning, and after lifting the rotating part 6, it restricts the first support assembly 7 to its original position and prevents it from shifting, making the support more stable. The bottom groove 11 is relatively shallow, and the overall length of the first support assembly 7 can be shortened by slightly rotating the first bolt 72 in the opposite direction a few times, allowing it to be disengaged from between the bottom groove 11 and the rotating part 6, facilitating quick adjustment of the position of the rotating part 6.
[0027] The structure of the second support assembly 8 is similar to that of the first support assembly 7. The second support assembly 8 includes a second base 81 and a second bolt 82. The second base 81 has a threaded hole, and the second bolt 82 is screwed into the threaded hole. A pad 73 is installed on the head of the second bolt 82. The top of the fixing member 5 has a fixing block 53 extending towards the grinding mechanism. A top groove 531 is machined on the bottom surface of the fixing block 53. The top groove 531 is located above the rotating member 6. When the rotating member 6 is in the second position, as shown in the attached figure... Figure 6 As shown, the second base 81 can be embedded in the top groove 531, and the second bolt 82 can be rotated and adjusted to the length at which the pad 73 abuts against the first support plate 61, thus holding the rotating part 6 against.
[0028] Support pads 64 are respectively installed on the outer sides of the first support plate 61 and the second support plate 62, so that the positioning is more accurate and the error is reduced when in contact with the first limiting surface 51 or the second limiting surface 52. The first support component 7 and the second support component 8 also abut against the support pads 64 when they are working.
[0029] An adjustment hole is machined on the side plate 63 of the rotating part 6. An adjustment bolt 10 is threadedly connected to the adjustment hole. The end of the adjustment bolt 10 extends to the inside of the rotating part 6. After the prism 30 is placed inside the rotating part 6, the adjustment bolt 10 can be tightened to quickly fix the prism 30. A pressure pad 101 is installed at the end of the adjustment bolt 10 to avoid damage to the surface of the prism 30.
[0030] In this embodiment, the rotating member 6 rotates 90° between the first position and the second position, which can conveniently polish the two mutually perpendicular surfaces of the prism 30 held by the rotating member 6.
[0031] The worktable 1 has a notch 12 machined on it to receive the residue after grinding. A negative pressure device 20 connected to the notch 12 is installed under the worktable 1 to suck up and collect the residue, preventing contamination. When the first support component 7 is not in use, a cover plate can be placed on the bottom groove 11 to prevent incompletely collected residue from falling into the bottom groove 11 and affecting the use of the first support component 7.
[0032] This utility model prism grinding device has a simple structure. It can be manufactured using common parts and some simple turning and milling operations. It is easy to manufacture and has low cost. It is convenient for on-site temporary processing of prisms in the research and development stage that have not yet been mass-produced. It is convenient for prototyping and adjustment, and can quickly adjust the position of the prism to complete the grinding of both sides. It is flexible and convenient to use.
[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
