Description

Technical Field

[0001] This utility model relates to the field of crystal processing, specifically to a split-type counterweight polishing buckle plate. Background Technology

[0002] The optical processing industry is booming, and the corresponding polishing process is also developing accordingly. However, the current technology still leans towards classical polishing techniques, and the fixtures used still need to be optimized.

[0003] The mounting plates used in current classical polishing are still quite primitive, being old-fashioned one-piece designs made entirely of aluminum alloy. They require lubrication after each use; otherwise, vibrations and other issues may occur, and the equipment's ejector pins and aluminum alloy contact points are prone to wear. Existing polishing processes and techniques cannot function without surface shaping and parallelism adjustments. When these adjustments are needed, weights are required on the mounting plates, but there are no pre-defined or fixed positions, so they can only be secured using tape or similar materials. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to design a split counterweight polished buckle plate, add a locking position of the pressure iron, form a standardized form, and thus improve efficiency and save costs.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a split-type counterweight polished buckle plate, comprising a buckle plate body, a bearing joint, and an arc-shaped pressure iron, wherein the bearing joint is detachably connected to the center of the top surface of the buckle plate body, and its central axis coincides with the central axis of the buckle plate body; the arc-shaped pressure iron is detachably connected to the arc-shaped groove on the top surface of the buckle plate body; the outer diameter of the bearing joint matches the curvature of the arc-shaped pressure iron; a ball bearing is embedded in the side of the bearing joint that abuts against the buckle plate body, and the service hole of the ball bearing matches the size of the ejector pin.

[0006] Furthermore, a retaining ring is provided above the ball bearing for limiting its position.

[0007] In one preferred embodiment, the bearing connector has a through hole at its center and a protruding structure on the side that abuts against the main body of the buckle plate. The main body of the buckle plate has a circular groove at its center that mates with the protruding structure of the bearing connector to ensure overall concentricity. The bearing connector also has a countersunk hole for connection to the main body of the buckle plate via a countersunk screw.

[0008] Furthermore, the main body of the buckle is a ring-shaped shell with a sample chamber at the bottom.

[0009] Preferably, the arc-shaped groove is provided along the circumference of the main body of the buckle plate.

[0010] Furthermore, the arc-shaped pressure iron is connected to the main body of the buckle plate with screws.

[0011] The main features of this utility model are: Firstly, a bearing is used at the ejector pin joint for detachable replacement. Secondly, the arc-shaped pressure iron can be modularly and standardized for fixed use. This extends the overall mold's service life, allows for quick replacement, enhances replaceability, and improves safety. Attached Figure Description

[0018] To better understand the technical solution of this utility model, the embodiments of this utility model are described in detail below with reference to specific examples. It should be understood that the described embodiments are merely some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The singular forms “a,” “the,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. The test materials used in this utility model are all common commercially available products.

[0020] Reference Figures 1 to 4The illustrated split-type counterweight polishing buckle includes a buckle body 3, a bearing connector 2, and an arc-shaped pressure iron 1. The bearing connector 2 is detachably connected to the center of the top surface of the buckle body 3, with its central axis coinciding with the central axis of the buckle body 3. The arc-shaped pressure iron 1 is detachably connected to an arc-shaped groove 12 on the top surface of the buckle body 3. The outer diameter of the bearing connector 2 matches the curvature of the arc-shaped pressure iron 1. A ball bearing 24 is embedded in the side of the bearing connector 2 that abuts against the buckle body 3. The ball bearing 24 has a hole 25, the size of which matches the size of the ejector pin. The ball bearing 24 is limited by a retaining ring 26. The ball bearing 24 requires a tight fit during pressing. Its rolling property during use improves production stability, extends tooling life, and eliminates the need for lubrication. Due to its detachability, replacement and maintenance costs are reduced. The arc-shaped groove 12 is set along the circumference of the buckle body.

[0021] In one preferred embodiment, the bearing connector 2 has a through hole 22 at its center, and the ball bearing 24 is placed inside the through hole 22. A protruding structure 21 is provided on the side of the bearing connector 2 that abuts against the main body 3 of the buckle plate. A circular groove 11 is provided at the center of the main body 3 of the buckle plate, which engages with the protruding structure 21 of the bearing connector 2 to ensure overall concentricity. The bearing connector 2 is fixed to the main body 3 of the buckle plate through a countersunk hole 23.

[0022] In one preferred embodiment, the main body 3 of the buckle plate is an annular shell shape, and a sample cavity 13 is provided at its bottom.

[0023] In one preferred embodiment, the arc-shaped pressure iron 1 is provided with screw through holes and is fixedly connected to the main body 3 of the buckle plate. The arc-shaped pressure iron 1 can be matched and processed according to requirements, and its weight can be appropriately adjusted according to polishing adjustment speed, etc. The arc-shaped pressure iron 1 is screwed to the main body 3 of the buckle plate.

[0024] In use, the sample to be polished is placed in the sample cavity 13 of the main body 3 of the buckle plate. A pin on the transmission mechanism of the polishing equipment is inserted through the bearing joint 2 of this invention and contacts the ball bearing 24. Through the friction between the two, the pin rotates the main body 3 of the buckle plate, thereby polishing the sample. During use, the weight of the arc-shaped pressure iron 1 can be changed according to the parallelism of the polished sample to adjust the surface shape. The weight and size can be changed and reserved according to needs.
