Description
Technical Field
[0001] This utility model belongs to the field of planer blade sharpening technology, specifically relating to a planer blade flat grinding and fine sharpening tool. Background Technology
[0002] Planer blades are important tools widely used in woodworking, metalworking, and other fields. Their structure is as follows: Figure 5 As shown, planer blades are mainly used for fine sanding and smoothing of wood or metal surfaces. They help remove burrs and uneven parts from the material surface, ensuring the smoothness and aesthetics of the final product. The planer blade needs to be sharpened on both sides. The traditional sharpening method is to clamp and fix the planer blade with a clamp, and then sharpen both sides separately. However, without a reference platform for fixation, it will result in inconsistent or uneven sharpening angles on both sides. Therefore, it is necessary to clamp the planer blade with a reference platform with a certain tilt angle before sharpening both sides separately. Utility Model Content

By setting a first clamping part and a second clamping part on the base, and setting multiple clamping components on both the first clamping part and the second clamping part, the unsharpened planing blade is clamped by the first clamping part, so that the planing blade is tilted on the first clamping part and one side of the planing blade is sharpened. Then the planing blade with one sharpened side is placed on the second clamping part. The relief groove on the second clamping part can give way to the sharpened side of the planing blade, thereby protecting the sharpened side and performing the sharpening operation on the unsharpened side, so that the sharpening angles on both sides are consistent.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0023] Example 1:
[0024] A tooling fixture for surface grinding and fine edge sharpening of planer blades, such as Figure 1 , Figure 2 and Figure 4As shown, the device includes a base 1 and several clamping components 5. The base 1 is a trapezoidal structure. A first clamping part 2 is provided on the left side of the base 1, and a second clamping part 3 is provided on the right side of the base 1. The clamping components 5 are distributed at the positions of the first clamping part 2 and the second clamping part 3, and are spaced apart on the first clamping part 2 and the second clamping part 3. The first clamping part 2 is used to clamp an unsharpened planing blade, and the second clamping part 3 is used to clamp a planing blade with one side sharpened. The first clamping part 2 fixes the unsharpened planing blade so that one side protrudes above the base 1. The protruding side is sharpened by a sharpening device, and then it is removed, flipped over, and clamped by the second clamping part 3 to sharpen the other side. After the planing blade is clamped, the plane on the side above the base 1 is higher than the plane on the top of the base 1, so that the planing blade protrudes from the top of the base 1, which facilitates the sharpening operation. The clamping assembly 5 includes a limiting bolt 52, a spring 53, and a limiting member 51. The limiting member 51 has a through hole in the middle. The limiting bolt 52 passes through the through hole and is connected to the base 1. The spring 53 is sleeved on the limiting bolt 52 and abuts against the base 1 and the limiting member 51 respectively. The spring 53 supports and lifts the limiting member 51, allowing the limiting member 51 to open and close on the limiting bolt 52. A mounting groove is provided at the central axis of one side of the planer blade. The limiting member 51 can be inserted into the mounting groove to press and fix the planer blade. The limiting member 51 includes a clamping part 511 and a limiting part 512. The clamping part 511 abuts against the mounting groove of the planer blade. After the clamping part 511 is inserted into the mounting groove, it clamps the planer blade on the first clamping part 2 or the second clamping part 3 of the base 1 to make it stable. The first clamping part 2 and the second clamping part 3 are both provided with limiting grooves 4. The limiting part 512 is inserted into the limiting groove 4 and is limited by the limiting groove 4. The limiting groove 4 can prevent the limiting member 51 from rotating axially along the limiting bolt 52, so that the clamping part 511 of the limiting member 51 is aligned with the mounting groove of the planer blade. At the same time, the limiting groove 4 has a certain depth. When the clamping part 511 of the limiting member 51 is lifted, the limiting part 512 of the limiting member 51 will move down and penetrate into the limiting groove 4. The limiting groove 4 can provide the limiting part 512 of the limiting member 51 with a certain range of motion, so that the limiting member 51 can open and close.
[0025] Example 2:
[0026] This embodiment, based on the above embodiment, further defines the first clamping part and the second clamping part, such as... Figure 1 , Figure 2 and Figure 3As shown, the first clamping part 2 includes a first connecting surface 22 and a first clamping surface 21. The first clamping surface 21 has an inclined structure, and its inclination is set according to the processing requirements of the planer blade. The first clamping surface 21 is located near the top of the base 1. The first connecting surface 22 is located below the first clamping surface 21. The first connecting surface 22 is also inclined and protrudes below the first clamping surface 21. The limiting bolt 52 of the first clamping part 2 is threadedly connected to the first connecting surface 22 to position the limiting member 51. The second clamping part 3 includes a second connecting surface 32 and a second clamping surface 31. The second clamping surface 31 has an inclined structure and is located near the top of the base 1. The second connecting surface 32 is located below the first clamping surface 21. The second connecting surface 32 is also inclined and protrudes below the second clamping surface 31. The limiting bolt 52 of the second clamping part 3 is threadedly connected to the second connecting surface 32 to position the limiting member 51. A clearance groove 311 is provided between the second connecting surface 32 and the second clamping surface 31. The clearance groove 311 is an arc-shaped groove structure. The clearance groove 311 is used to make way for the sharpening side of the planer blade. When the planer blade, which has been sharpened on one side, is sharpened on the other side, its sharpened side will slide into the clearance groove 311, preventing wear on the already sharpened edge when sharpening the other side. An abutment surface 321 is provided at the end of the connecting surface above the clearance groove 311. The abutment surface 321 is an inclined surface that slopes towards the clearance groove 311 and abuts against the sharpening surface of the planer blade, so that the sharpening side of the planer blade is suspended in the clearance groove 311 and does not contact the bottom or edge of the clearance groove 311, further protecting the cutting edge of the planer blade. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again here.
[0027] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
