Description

Technical Field

[0001] This utility model relates to the field of polishing equipment, specifically a fixing device for polishing fluoride crystal rods. Background Technology

[0002] Fluoride elongated crystal rods are used in high-precision optical components (such as laser resonator cavities), requiring ultra-smooth and defect-free end faces. Existing technologies often employ traditional fixing methods, bonding multiple crystal rods together to increase the stress area and enhance stability. Pressure is then applied from the top, causing the end faces to be ground on a polishing pad. However, this process introduces numerous defects, such as:

[0003] 1) A large number of crystal rods are required to achieve the desired effect, which can easily lead to material waste;

[0004] 2) The material is soft and brittle with a large length-to-diameter ratio, resulting in high polishing stress points and instability during processing. This can easily lead to end face tilting or vibration, causing edge chipping. At the same time, uneven polishing pressure distribution makes it difficult to meet surface profile standards.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1 to 8 The figure shows a preferred embodiment of the present invention, which discloses a fixing device for polishing fluoride crystal rods, including a rod disk 1 and a cover plate, wherein...

[0034] The crystal rod tray 1 includes a disk 101, and a plurality of grooves 104 are provided on the outer edge of the disk 101. The grooves 104 are used to place crystal rods, and each groove 104 corresponds to at least one cover plate.

[0035] The cover plate is provided with a corresponding groove. The cover plate includes a main body 201 and a second protrusion 203 provided with a corresponding groove 104. The two ends of the main body 201 are connected to the disk 101, and the cover plate locks the crystal rod in the corresponding groove.

[0036] The disc 101 can be a metal disc, and the cover plate can be a metal cover.

[0037] The design of the groove 104 allows for better compatibility with various small-diameter crystal rods (crystal rods with diameters ranging from 5 to 16 mm). The groove 104 can be V-shaped, and it has two groove walls 105. The inner ends of the two groove walls 105 in the same groove 104 are connected, and the included angle between the two groove walls 105 in the same groove 104 is a°, where a can range from 85° to 95°. The distance between the outer ends of the two groove walls 105 in the same groove 104 (i.e., the direction in which the groove 104 opens) is L1, where L1 can range from 31.9 to 32.1 mm. The distance from the outer end to the inner end of the same groove wall 105 is L2, where L2 can range from 15.9 to 16.1 mm. The distance from the outer end of the groove wall 105 to the center of the disk 101 is L3, where L3 can range from 93.9 to 94.1 mm. Each groove wall 105 has a connecting end face 106 connected to its outer end. The connecting end face 106 and the cover plate can be detachably connected. For example, through holes 202 are provided at both ends of the main body 201, and countersunk holes 108 are provided on the connecting end face 106 corresponding to the through holes 202. By using connectors (such as bolts, screws, etc.) to pass through the through holes 202 and insert them into the countersunk holes 108 and lock them in place, the cover plate can be connected to the crystal rod disk 1.

[0038] Several grooves can be evenly distributed circumferentially on the outer edge of the disk 101.

[0039] The disk 101 can be divided into an inner disk 111 and an outer disk 112 arranged coaxially. The outer disk 112 surrounds the inner disk 111, and the height of the top surface of the inner disk 111 is greater than the height of the top surface of the outer disk 112, thus forming a stepped structure. A first protrusion 102 is provided in the middle of the inner disk 111, and a first groove 103 is provided on the first protrusion 102. A second groove 107 can be added to the bottom of the disk 101. The second groove 107, the first groove 103, the first protrusion 102, and the disk 101 can be arranged coaxially. In some specific implementations, the first groove 103 and the second groove 107 are not connected.

[0040] The fixing device for polishing fluoride crystal rods may also include a terminal cover 3 adapted to the rod disk 1. The terminal cover 3 is connected to the connecting rod of the polishing equipment, which can drive the polishing disk below to rotate. This connection structure and transmission process can be directly implemented using existing technology, so it will not be described in detail here. The terminal cover 3 includes a terminal cover body 301, a third groove 302 and a fourth groove 303 arranged coaxially. The third groove 302 and the fourth groove 303 are respectively disposed on the upper and lower sides of the terminal cover body 301. The fourth groove 303 is adapted to the first protrusion 102.

[0041] In use, place the crystal rod in the groove 104, with the bottom of the crystal rod slightly extending beyond the crystal rod disk 1. The height of the bottom of the crystal rod extending beyond the crystal rod disk 1 can be 1-2 mm. After positioning, apply glue to the gap between the crystal rod and the groove 104 to fix the crystal rod, and cover the opening of the groove 104 with a cover plate and lock it. The crystal rod disk 1 and the crystal rod are fixed as a whole on the polishing machine. Driven by the polishing machine (such as a classic four-axis polishing machine), the end face of the crystal rod moves relative to the polishing pad to achieve polishing of the end of the crystal rod.

[0042] All of the above-mentioned undisclosed matters can be implemented using existing technologies, so they will not be elaborated here.
