Description

Technical Field

[0001] This utility model relates to the field of aluminum processing, specifically to an aluminum polishing limiting fixture. Background Technology

[0002] In the aluminum processing industry, especially in the aluminum polishing process, precise workpiece positioning plays a decisive role in product quality. Currently, the industry commonly uses specialized polishing fixtures to position and fix aluminum materials. These specialized fixtures are usually custom-designed according to aluminum materials of specific shapes and sizes, and their structure and the layout of positioning components are matched to the single specification of aluminum material.

[0003] When dealing with various aluminum materials of different specifications, the limitations of traditional dedicated polishing fixtures become increasingly apparent. Due to the fixed structural characteristics of dedicated fixtures, their positioning methods lack flexibility and cannot meet the precise positioning requirements of diverse aluminum materials. Whenever a new shape of aluminum material needs to be processed, companies must redesign and manufacture new dedicated fixtures, resulting in a significant increase in fixture development costs. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum polishing limiting fixture to solve the problem of poor versatility of traditional polishing limiting fixtures mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum polishing limiting fixture, comprising a base plate and a positioning plate disposed on the top of the base plate, wherein a plurality of positioning pins are detachably mounted on the top of the positioning plate, and a plurality of screw holes for accommodating the positioning pins are provided on the top of the base plate, wherein an L-shaped plate is rotatably mounted on the top of the positioning pins, and a screw is detachably mounted on the L-shaped plate.

[0006] Preferably, the positioning pin is threadedly connected to the screw hole.

[0007] Preferably, the top of the positioning pin is integrally formed with a stepped portion, and the L-shaped plate is rotatably mounted on the side wall of the stepped portion via a pivot.

[0008] Preferably, a threaded sleeve is fixedly installed at the end of the L-shaped plate, and the screw is threadedly connected to the threaded sleeve.

[0009] Preferably, the end of the screw has an arc-shaped structure.

[0010] Preferably, the corners of the positioning pin are rounded for a smooth transition.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, by setting multiple screw holes and flexibly installable positioning pins, enables the same positioning plate to adapt to various aluminum materials of different shapes. Compared with the traditional method of requiring customized polishing fixtures for each type of aluminum material, it effectively reduces the development cost and time investment of fixtures, improves the flexibility and versatility of polishing positioning, meets the diverse positioning needs in the aluminum material processing process, and has high practical value.

[0018] 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.

[0019] Please see Figures 1-4 This utility model provides a technical solution: an aluminum polishing limiting fixture, including a base plate 1 and a positioning plate 2 disposed on the top of the base plate 1. The positioning plate 2 is fixedly installed on the top of the base plate 1. Several positioning pins 4 are detachably installed on the top of the positioning plate 2. The corners of the positioning pins 4 are rounded to avoid sharp corners that could scratch the skin. The positioning pins 4 are threadedly connected to screw holes 3. The top of the base plate 1 is provided with several screw holes 3 for accommodating the positioning pins 4. The screw holes 3 are arranged in a regular array. An L-shaped plate 5 is rotatably installed on the top of the positioning pins 4. A stepped portion 8 is integrally formed on the top of the positioning pins 4. The L-shaped plate 5 is rotatably installed on the side wall of the stepped portion 8 via a rotating shaft 7. A screw rod 6 is detachably installed on the L-shaped plate 5. A screw sleeve 9 is fixedly installed on the end of the L-shaped plate 5. The screw rod 6 is threadedly connected to the screw sleeve 9. The end of the screw rod 6 is provided with an arc-shaped structure.

[0020] In practical use, when positioning aluminum materials of different shapes is required, operators can selectively screw the positioning pins 4 into the screw holes 3 at different positions according to the shape and positioning requirements of the aluminum material. By rationally arranging the positions of the positioning pins 4, a positioning structure that matches the shape of the aluminum material to be positioned can be formed, thereby achieving precise positioning of the aluminum material.

[0021] For rectangular aluminum materials, the positioning pins 4 can be screwed into the screw holes 3 at the four corners of the positioning plate 2 corresponding to the rectangle. For irregularly shaped aluminum materials, multiple suitable screw holes 3 can be selected to install the positioning pins according to their contour characteristics. The length of the screw rod 6 can be adjusted as needed. Some irregularly shaped aluminum materials have complex structures such as recesses and protrusions. By adjusting the length of the screw rod 6, its end can be made to penetrate into the recessed part of the aluminum material or go beyond the protruding part, so as to accurately fit its contour for positioning and ensure that the height of the positioning pin 4 protruding from the screw hole 3 is lower than the thickness of the polished aluminum material.

[0022] This application, by setting multiple screw holes 3 and flexibly installable positioning pins 4, enables the same positioning plate 2 to adapt to various aluminum materials of different shapes. Compared with the traditional method of customizing special polishing fixtures for each type of aluminum material, it effectively reduces the development cost and time investment of fixtures, improves the flexibility and versatility of polishing positioning, meets the diverse positioning needs in the aluminum material processing process, and has high practical value.
