Description

Technical Field

[0001] The utility model belongs to the field of mechanical processing, relates to clamping and positioning, and is specifically a grinding auxiliary tool for non-magnetic materials. Background Art

[0002] The application field of finishing the end faces of non-magnetic workpieces with small size and light weight will have obvious clamping and positioning problems. Since such workpieces are made of non-magnetic materials with small size and light weight, they are limited by the material properties and their own weight. When finishing the end faces of the workpieces on a surface grinder using conventional methods, the processing efficiency is extremely low and cannot be adapted to mass production.

[0003] Taking a certain product stopper as an example, the existing technical solution is explained: the block shape structure is as follows: Figure 1 and Figure 2 As shown, the material is molybdenum-based alloy, the thickness size High precision is required, requiring grinding on a surface grinder. However, due to its small dimensions and the non-magnetic nature of molybdenum-based alloys, it cannot be attracted to the surface grinder's magnetic table. Therefore, when grinding both ends of the workpiece, it must be held by a thin baffle that can be attracted to the table or clamped with flat-nose pliers. However, due to the weak magnetic force of the baffle and the clamping method, only a small amount or a single piece of workpiece can be ground at a time. This machining solution is inefficient and cannot meet the needs of high-volume production. Utility Model Content

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0024] In the description, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance. It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms based on specific circumstances.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] A grinding tool made of non-magnetic material, comprising a magnetic grinding tool body 1, the grinding tool body 1 is in the shape of a plate, and a plurality of positioning grooves 11 are provided on the plate surface of the grinding tool body 1, such as Figure 3 As shown, the lower opening of the positioning groove 11 is a right angle, and the upper opening is set as an inner fillet 12. The diameter of the inner fillet 12 is not less than the outer fillet of the workpiece 3 to be ground. The thickness of the grinding auxiliary tool body 1 is less than the thickness of the workpiece 3 to be ground. The positioning grooves 11 are evenly distributed on the grinding auxiliary tool body 1, and a circular hole 13 that passes through the positioning groove 11 is processed at the four corner positions of the positioning groove 11.

[0028] In this embodiment, the fillet 12 of the positioning groove 11 serves two purposes. First, it allows the grinding tool body 1 to press the workpiece 3. Second, after the grinding tool body 1 presses the workpiece 3, the end surface of the workpiece 3 to be machined can be raised above the upper end surface of the grinding tool body 1. In this embodiment, the end surface of the workpiece 3 to be machined can be raised above the upper end surface of the grinding tool body 1 by 0.2 to 0.3 mm.

[0029] In this embodiment, the tool used to process the positioning groove 11 is a circular tool, so only arcs can be processed at the right angles. If the length and width of the positioning groove 11 are exactly the same as the size of the workpiece 3, the right-angled part of the workpiece 3 cannot be placed in the positioning groove 11. Therefore, a circular hole 13 will be punched in the right-angled part of the positioning groove 11 before processing the positioning groove 11.

[0030] In this embodiment, through the magnetic attraction between the grinding auxiliary tool body 1 and the worktable 2 of the surface grinder, and under the action of the gravity of the grinding auxiliary tool body 1 itself, the bottom surface of the workpiece 3 is tightly attached to the surface of the magnetic worktable 2 of the surface grinder, thereby solving the clamping and positioning problems of the workpiece 3, improving production efficiency, and ensuring the processing quality of the workpiece 3.

[0031] The application process of this embodiment is as follows: Use workpiece 3 as Figure 1 and Figure 2 As shown, L1 represents the height of workpiece 3, L2 represents the width of workpiece 3, and L3 represents the length of workpiece 3. The tolerance is as follows Figure 1 and Figure 2 As shown in , R3 represents the four outer corner radii of workpiece 3. Figure 4 As shown, the number of the positioning grooves 11 is 10, L2' represents the width of the positioning groove, and L3' represents the length of the positioning groove.

[0032] 1) Place the workpiece 3 with the end surface to be ground facing upwards on the workbench 2 at a certain distance, then place the grinding tool body 1 on the workpiece 3 with the right-angle side of the positioning groove 11 facing downwards, ensuring that each workpiece 3 is placed in the corresponding positioning groove 11.

[0033] 2) Then, turn on the magnetic switch of the grinding machine worktable 2, and place the inner fillet 12 in the positioning groove 11 of the grinding tool body 1 close to the outer fillet R3 of the workpiece 3 to limit the displacement of each workpiece 3. At the same time, through the magnetic attraction between the grinding tool body 1 and the worktable 2 of the surface grinder, as well as the gravity of the grinding tool body 1 itself, the bottom surface of the workpiece 3 is tightly attached to the magnetic worktable 2 of the surface grinder.

[0034] 3) Start grinding the upward end surface of the workpiece 3;

[0035] 4) After finishing the top surface of workpiece 3, turn off the magnetic switch of grinder table 2, cut off the magnetic attraction between grinding tool body 1 and surface grinder table 2, remove workpiece 3, turn each workpiece 3 180°, re-clamp workpiece 3, and grind the other end surface of workpiece 3 according to the operation steps 1)-3) to ensure the size. .

[0036] It should be noted that:

[0037] (1) The grinding tool body 1 may become skewed during use due to the different grinding amounts of the workpiece 3. However, since the grinding amount of the workpiece 3 is relatively small, approximately 0.2 mm, even if the grinding tool body 1 is slightly skewed, it can still press the workpiece 3 and be well sucked onto the workbench 2 of the surface grinder, without affecting the grinding accuracy of the workpiece 3.

[0038] (2) During use, the inner fillet 12 of the positioning groove 11 of the grinding tool body 1 needs to press the outer fillet of the workpiece 3.

[0039] (3) After the grinding tool body 1 and the workpiece 3 are installed, the grinding tool body 1 should maintain a gap of 0.3 to 0.5 mm with the workbench 2.

[0040] This embodiment uses the grinding auxiliary tool to process block-type parts, which can be found to be an easy-to-operate, economical, safe, efficient and reliable processing method, and is very suitable for large-scale grinding production and processing of small-sized, light-weight non-magnetic material parts.

[0041] The advantages of the present invention are that the processing efficiency of the product is improved and the processing quality is guaranteed. The grinding tool can process ten workpieces 3 at the same time, greatly improving the processing efficiency of the product.

[0042] The above description is only a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions have been made with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and such modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the technical solutions of the embodiments, and they should all be covered by the scope of protection of the claims.
