Description

Technical Field

[0001] This utility model belongs to the field of crystal fixing fixture technology, and in particular relates to a clamping mechanism for crystal processing. Background Technology

[0002] Crystal processing requires cutting the crystal from a columnar structure into a thin sheet structure. A common cutting method is to fix the crystal perpendicular to the ground along its axis and then use cutting equipment to move along a horizontal plane to cut the crystal.

[0003] Currently, the fixtures used to fix crystals are usually placed on the carrier plate that receives the crystal. When the crystal diameter changes, the position of the fixture needs to be adjusted. Adjusting the position of the fixture requires cumbersome disassembly and assembly, which affects the adjustment efficiency of the fixture. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model embodiment provides a clamping mechanism for crystal processing, such as... Figures 1-6 As shown, the clamping mechanism for crystal processing is used for crystal fixing during crystal cutting and includes:

[0025] The fixed base 210 and the sliding base 220 slide on the fixed base 210. The fixed base 210 is provided with a sliding cavity 201 with one end being an open port. The sliding base 220 extends from the open port of the sliding cavity 201 into the sliding cavity 201. The fixed base 210 and the sliding base 220 together form a clamping assembly 200. Typically, the number of clamping assemblies 200 is not less than four.

[0026] The crystal cutting process uses a base 101 and a support plate 102 mounted on the base 101. Typically, the crystal is placed with its axis perpendicular to the support plate 102. The cutting equipment in this application specifically refers to a wire cutting machine. During processing, the cutting equipment processes the crystal parallel to the base 101 and the support plate 102. The base 101 may also be reinforced by a rocking motion as needed. The above content describes existing crystal slicing techniques and will not be elaborated upon here. This application mainly proposes improvements to the clamping structure used for crystal fixing. In this application, the fixing seat 210 is pre-arranged on the support plate 102 in an array distribution using bolts. When the crystal diameter changes, there is no need to adjust the position of the fixing seat 210; the sliding seat 220 is directly replaced. Here, a suitable length of sliding seat 220 is selected based on the crystal diameter change and inserted into the sliding cavity 201 to ensure that the sliding seat 220 can reach near the crystal sidewall after replacement. Minor discrepancies are mainly adjusted by pushing the sliding seat 220 to slide.

[0027] The specific structure of the sliding cavity 201 is as follows: one end of the sliding cavity 201 is an open port serving as the insertion port of the sliding seat 220, while the end face of the sliding cavity 201 away from the bearing plate 102 is provided with a cover plate 230 for semi-enclosure. Here, the side of the cover plate 230 away from the open port and the sliding cavity 201 are distributed in an intermittent manner. The side of the cover plate 230 near the open port is provided with a limiting block 240 that can extend into the sliding cavity 201. The limiting block 240 is inserted into the cover plate 230. The sliding seat 220 is provided with a positioning groove 205. The part of the limiting block 240 extending into the sliding cavity 201 is inserted into the positioning groove 205. The end of the positioning groove 205 inserted into the sliding cavity 201 is provided with a baffle. When the end of the positioning groove 205 inserted into the sliding cavity 201 reaches the vicinity of the open port, the limiting block 240 prevents the sliding seat 220 from sliding out of the sliding cavity 201.

[0028] In this application, the assembly is completed by the movable and detachable sliding seat 220 and the fixed seat 210. When the crystal clamping diameter changes, the sliding seat 220 of appropriate length is selected to complete the clamping and fixing, reducing the need for disassembly and assembly of the fixed seat 210 and improving the adjustment efficiency of the clamping mechanism during the production transition.

[0029] As a preferred embodiment of this embodiment, the side wall of the fixed seat 210 away from the open port is also provided with a locking bolt 250, which extends from the outside of the fixed seat 210 to the sliding cavity 201 and abuts against the sliding seat 220.

[0030] In this embodiment, the locking bolt 250 extends into the sliding cavity 201 through a threaded hole on the side wall of the fixed seat 210. By pre-selecting the length of the sliding seat 220, the sliding seat 220 is as close as possible to the outer side wall of the crystal. In the final locking stage, the locking bolt 250 is screwed in to push the sliding seat 220 to slide with the fixed seat 210 to ensure that the sliding seat 220 can contact the side wall of the crystal to complete the clamping.

[0031] In a preferred embodiment of this invention, the sliding seat 220 includes a slider 221 and a flexible block 222. The flexible block 222 is disposed at the front end of the slider 221 and is in contact with the crystal. The length of the slider 221 is greater than the depth of the sliding cavity 201.

[0032] In this embodiment, the flexible block 222 is made of the same material as the clamp structure in the prior art, which is silicone or rubber, mainly to avoid damage to the crystal caused by hard contact; the side wall of the sliding cavity 201 is also provided with a limiting slide rail 203, and the side wall of the sliding seat 220 is provided with a limiting slide groove 204 that is adapted to the limiting slide rail 203. The sliding seat 220 slides in the sliding cavity 201, and the limiting slide groove 204 is engaged with the limiting slide rail 203 and slides along the limiting slide rail 203;

[0033] In a further preferred embodiment of the present invention, the cover plate 230 is provided with a slot 202 that penetrates the cover plate 230, and the limiting block 240 has a T-shaped structure, with one end of the limiting block 240 extending into the sliding cavity 201 through the slot 202;

[0034] In a further embodiment, the cover plate 230 is also provided with an embedding groove that can accommodate the limiting block 240. The limiting block 240 is composed of a crossbeam part and a vertical insert part. The embedding groove accommodates the crossbeam part, improving the connection between the limiting block 240 and the cover plate 230. The slot 202 is then arranged at the bottom of the embedding groove.
