Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a grinding tool fixture. Background Technology

[0002] As is well known, when shearing metal for a long time, the blades of a shearing machine are easily dulled due to machine pressure, bending stress, large mechanical friction and a small amount of impact. Therefore, after a period of use, the blades of the shearing machine usually need to be sharpened.

[0003] However, the inventors discovered through research that, in existing methods of sharpening the blades of a shearing machine, the blades are typically placed on... Figure 1 As shown in the vise, because there is no table surface to support the blades, the blades have different angles after each grinding, and the cutting edges of multiple blades are not parallel. When they are subsequently installed on the shearing machine, problems such as uneven cutting at the feed opening, incomplete cutting of products, or curled edges at the feed opening often occur. This not only reduces production efficiency but also increases the product scrap rate.

[0004] Therefore, existing sharpening fixtures still have shortcomings in the installation and sharpening of blades, and there is an urgent need to design a new sharpening fixture to optimize the sharpening effect of blades. Utility Model Content

[0005] The technical problem to be solved by this utility model is: This utility model discloses a new type of sharpening fixture to solve the problem that when the existing bench vise is used as a sharpening fixture, it cannot effectively support the blade, resulting in inconsistent blade sharpening angles and poor sharpening quality each time.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a sharpening fixture, comprising a base, wherein an opening groove for supporting a blade is provided on the base, the opening groove is inclined to the upper surface of the base, and the inclination angle of the opening groove relative to the upper surface of the base is the same as the cutting edge angle of the blade; wherein the base is also provided with a plurality of fixing holes, the fixing holes communicating with the opening groove, and the fixing holes are used to install fixing components, the fixing components being used to lock the position of the blade in the opening groove.

[0007] Furthermore, in the sharpening fixture of this utility model, a plurality of blades are arranged sequentially in the opening groove along the length direction of the base.

[0008] Furthermore, in the sharpening fixture of this utility model, a plurality of fixing holes are distributed in a rectangular array on the upper surface of the base, and are sequentially arranged in the length direction of the base corresponding to a plurality of blades.

[0009] Furthermore, in the sharpening fixture described in this utility model, the opening groove is provided through both the front and rear ends of the base in the length direction of the base.

[0010] Furthermore, in the sharpening fixture of this utility model, the opening of the slot is located on the upper surface of the base, and at least part of the blade extends out from the opening of the slot.

[0011] Furthermore, in the sharpening fixture of this utility model, the blade includes a locking part and a cutting edge part. The top end of the locking part is connected to the cutting edge part. The locking part is accommodated in the opening groove, and the cutting edge part extends out from the opening of the opening groove.

[0012] Furthermore, in the sharpening fixture of this utility model, the blade portion includes a first blade edge and a second blade edge. The first blade edge is disposed parallel to the upper surface of the base, and the inclination angle of the second blade edge relative to the upper surface of the base is the same as the inclination angle of the opening groove relative to the upper surface of the base.

[0013] Furthermore, in the sharpening fixture described in this utility model, the included angle between the first cutting edge and the second cutting edge is the cutting angle of the blade.

[0014] Furthermore, in the sharpening fixture described in this utility model, the fixing member is threadedly connected to the fixing hole, and one end of the fixing member extending into the fixing hole abuts against the blade in the opening groove.

[0015] Furthermore, in the grinding fixture described in this utility model, the axial direction of the fixing hole is perpendicular to the inclination direction of the opening groove.

[0016] The beneficial effects of this utility model are as follows: The grinding fixture designed in this utility model has an optimized base structure. By setting an opening groove on the base to accommodate the blade, and setting the inclination angle of the opening groove relative to the upper surface of the base to be the same as the blade's cutting angle, the blade can be effectively supported. Combined with the use of fixing components to lock the position of the blade in the opening groove, the installation position of the blade on the fixture is effectively limited, ensuring that the opening groove can effectively support the blade during grinding, guaranteeing the blade grinding angle, and ensuring that the cutting angle of each blade ground is the same, thus improving the blade grinding effect. It has good prospects for promotion and application value.

[0017] Meanwhile, the grinding fixture designed in this utility model uses fixed blades set in fixed holes. Unlike a bench vise, it is not restricted in its movement. As long as it is within the processing range of the grinding machine, the grinding fixture can be made wider to clamp more blades and improve grinding efficiency. Attached Figure Description

[0020] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] See Figure 1 As shown, when sharpening the blade 2, the blade 2 is usually placed directly on the horizontal surface of the vise 3 without any specific support. The operator manually controls the push rod 31 to drive the push plate 32 to clamp the blade 2 for sharpening. In subsequent sharpening, since the blade 2 is only clamped along the length of the vise 3 and there is no effective support, the blade 2 has different angles and the cutting edges are not parallel after each sharpening, making it difficult to obtain a good sharpening effect.

[0022] Therefore, please refer to Figure 2 and Figure 3 As shown, this utility model discloses a new sharpening fixture that can effectively support and fix the blade 2, ensuring that the cutting edge angle of each blade 2 sharpened is the same, thus improving the sharpening effect of the blade 2. In this utility model, the sharpening fixture includes: a base 1, on which an opening groove 11 for supporting the blade 2 is provided. The opening groove 11 is inclined to the upper surface of the base 1, and the inclination angle of the opening groove 11 relative to the upper surface of the base 1 is the same as the cutting edge angle of the blade 2. The base 1 is also provided with a plurality of fixing holes 12, which are connected to the opening groove 11 and are used to install fixing members 13. The fixing members 13 are used to lock the position of the blade 2 in the opening groove 11, thereby ensuring that the position of the blade 2 is locked.

[0023] In other words, in practical applications, to prevent the angle of the blade 2 from changing during grinding, the grinding fixture directly provides an opening groove 11 on the base 1 to accommodate and support the blade 2, and limits the inclination angle of the opening groove 11 relative to the upper surface of the base 1 to be the same as the cutting edge angle of the blade 2, thereby limiting the grinding angle of the blade 2 and ensuring that the angle of the blade 2 is the same each time it is ground; at the same time, the fixing member 13 locks the position of the blade 2 in the opening groove 11 to ensure that the blade 2 will not shift or change position during grinding, thereby improving the grinding quality.

[0024] Of course, to improve grinding efficiency, multiple blades can be ground at once. For actual installation and setup, please refer to [the relevant documentation / reference]. Figure 3 As shown, during polishing, the polishing is specifically carried out along the width direction of base 1 (see...). Figure 3 The blade 2 is ground in the X direction (as shown), therefore, in the length direction of the base 1 (see...) Figure 3 As shown in the Y direction, multiple blades 2 can be arranged sequentially in the opening groove 11. Each blade 2 is set independently and can be polished synchronously, thereby greatly improving polishing efficiency.

[0025] Accordingly, since each blade 2 is independently set in the opening slot 11, in order to ensure that each blade 2 can be locked in the opening slot 11, multiple fixing holes 12 are specifically set in a rectangular array on the upper surface of the base 1, and multiple blades 2 are sequentially set in the length direction of the base 1, so as to match multiple fixing members 13 through these fixing holes 12, and thereby lock and position different blades 2 respectively.

[0026] Among them, see Figure 3 As shown, in this utility model, the fixing hole 12 can be specifically configured as a threaded hole, and the fixing member 13 can be specifically configured as a screw. When the fixing member 13 extends into the fixing hole 12, it can specifically establish a threaded connection between the fixing member 13 and the fixing hole 12, and one end of the fixing member 13 extending into the fixing hole 12 can abut against the blade 2 in the opening groove 11 to lock the position of the blade 2.

[0027] Accordingly, when the fastener 13 uses a screw, in order to achieve a better fixing effect, the hole axis direction of the fixing hole 12 can be further defined to be perpendicular to the inclined direction of the opening groove 11, so that the fixing rod can be perpendicularly abutted against the surface of the blade 2 in the opening groove 11, restricting the movement of the blade 2 in the opening groove 11.

[0028] In practical applications, to facilitate the installation of multiple blades 2, the aforementioned opening groove 11 can be specifically provided along the length of the base 1, penetrating both the front and rear ends of the base 1, to facilitate the installation and removal of the blades 2 and simplify the operation for the operator. Specifically, in this invention, the opening of the opening groove 11 is located on the upper surface of the base 1, and at least a portion of the blades 2 can extend from the opening of the opening groove 11 to facilitate the grinding of the blade edge.

[0029] Accordingly, see further Figure 4 As shown, in this sharpening fixture designed in this utility model, the blade 2 installed in the opening groove 11 of the base 1 can specifically include a locking part 21 and a cutting edge part 22. The top end of the locking part 21 is connected to the cutting edge part 22, and the locking part 21 of the blade 2 is accommodated in the opening groove 11 so that the cutting edge part 22 of the blade 2 can extend out from the opening of the opening groove 11, which facilitates the subsequent sharpening of the cutting edge part 22.

[0030] In practical applications, the blade portion 22 includes a first cutting edge 221 and a second cutting edge 222. The first cutting edge 221 is specifically arranged parallel to the upper surface of the base 1. The inclination angle of the second cutting edge 222 relative to the upper surface of the base 1 is the same as the inclination angle of the opening groove 11 relative to the upper surface of the base 1, so that the included angle of the first cutting edge 221 and the second cutting edge 222 is the cutting angle of the blade 2.

[0031] Of course, in practical applications, this utility model does not limit the specific size of the sharpening fixture. The size of the sharpening fixture can be changed according to the number and size of the required blades 2. By adjusting the size of the base 1 and the opening groove 11, it can be adapted to the needs of different blades 2, thereby effectively improving the sharpening efficiency and accuracy, ensuring that the blades 2 are fixed firmly, and that subsequent sharpening is uniform.

[0032] In summary, the grinding fixture designed in this utility model features an optimized design with an inclined slot 11 on the base 1. This slot 11 provides an inclined plane to support and accommodate the blade 2, ensuring the consistency of the blade angle during subsequent grinding. Furthermore, in practical applications, a fixing hole 12 and a fixing member 13 located in the fixing hole 12 are used to lock the position of the blade 2 in the slot 11, effectively limiting the installation position of the blade 2 on the fixture. This ensures that the slot 11 can effectively support the blade 2 during grinding, guaranteeing the grinding angle of the blade 2 and ensuring that the blade angle of each blade 2 produced is the same, thus improving the grinding effect of the blade 2. It has good prospects for promotion and application value.
