[0027] An embodiment of the utility model provides a kind of integrated fixture, referring to Figure 1 、 Figure 2 , comprising:

[0028] Fixture body 1, including first clamping plate 11 and second clamping plate 12, the first clamping plate 11 is integrally formed with the second clamping plate 12;

[0029] Positioning groove 2 is located in the second clamping plate 12, for limiting the position of workpiece;

[0030] Elastic deformation groove 3 is communicated with the positioning groove 2 and extends into the fixture body 1;

[0031] Locking piece 4, the locking piece 4 is detachably installed on the fixture body 1 and penetrates the elastic deformation groove 3 to adjust the width of the elastic deformation groove 3.

[0032] The embodiment solves the problems of existing fixture assembly, low precision and workpiece positioning difficulty. Through the integrally formed fixture structure, no additional assembly is needed, time and labor cost is saved, assembly error is avoided, the precision of the fixture is guaranteed;And by providing positioning groove 2 on the second clamping plate 12, the position of the workpiece can be limited to avoid the workpiece from slipping off the fixture, ensure the accurate alignment of the workpiece and the fixture, and improve the clamping efficiency. In the embodiment, the positioning groove 2 is arranged at the end of the second clamping plate 12, and the elastic deformation groove 3 is communicated with the positioning groove 2 and extends along the length direction of the fixture body 1.

[0033] Further, the elastic deformation groove 3 comprises a rectangular groove 31 and a stress groove 32, the rectangular groove 31 communicates with the stress groove 32, and the stress groove 32 is located on the side away from the locking piece 4 and the positioning groove 2, so as to prevent the first clamping plate 11 from being cracked due to frequent stress at a single point and prolong the service life of the clamp.

[0034] Further, the stress groove 32 is in the shape of a water droplet. In the embodiment, the stress groove 32 is preferably in the shape of a water droplet. The stress groove 32 in the shape of a water droplet can make the stress on the node position of the first clamping plate 11 more uniform during deformation, avoid stress concentration, reduce the vulnerability of the node position, and reduce the deformation of the workpiece and the wear of the clamp.

[0035] It should be noted that in other embodiments, the stress groove 32 can also be in the shape of a trapezoid, a semicircle or other shapes.

[0036] Further, the width of the elastic deformation groove 3 is 0.1-0.2 mm. The width of the elastic deformation groove 3 affects the degree of deformation of the first clamping plate 11, thereby affecting the size of the clamping force. When the width of the elastic deformation groove 3 is wider, the deformation of the first clamping plate 11 is greater, and the clamping force is smaller. Conversely, when the width of the elastic deformation groove 3 is narrower, the deformation of the first clamping plate 11 is smaller, and the clamping force is greater. Therefore, in the embodiment, the width of the elastic deformation groove 3 preferably ranges from 0.1 mm to 0.2 mm. The width in this range can provide moderate clamping force for the workpiece, which can facilitate the placement of the workpiece and enable the first clamping plate to clamp the workpiece through small deformation, thereby avoiding damage to the clamp caused by excessive deformation of the first clamping plate 11.

[0037] Further, the locking piece 4 is a screw, the clamp body 1 is provided with a threaded hole 5, and the screw connects the first clamping plate 11 and the second clamping plate 12 and penetrates the elastic deformation groove 3. When one end of the screw is screwed into the threaded hole 5 and penetrates the elastic deformation groove 3, the screw is continued to be tightened, the screw applies downward pressure to the elastic deformation groove 3, the elastic deformation groove 3 is elastically deformed, that is, the first clamping plate 11 is bent downward, thereby reducing the width of the elastic deformation groove 3, that is, reducing the gap between the first clamping plate 11 and the second clamping plate 12, and the clamp deforms to clamp the workpiece. In the embodiment, the threaded hole 5 is a through hole. When the operator needs to screw the screw into the threaded hole 5, the operator can directly observe the screwing depth and position of the screw, thereby avoiding the situation that the screw is not screwed in place and the situation that the screw is blocked halfway through, thereby avoiding the situation that the screw is blocked halfway through. In the embodiment, the locking piece 4 is a screw, which is preferably an internal hexagonal screw.

[0038] It should be noted that in other embodiments, the locking piece 4 can be a pin, a wedge or the like.

[0039] Further, the positioning groove 2 is formed by electric spark discharge.

[0040] Electric spark discharge machining is an advanced machining technology that uses electrical energy and mechanical energy to produce electric spark discharge on the workpiece material to achieve material removal and processing purposes. Electric spark discharge machining can achieve micron-level machining precision. The positioning groove 2 formed by electric spark discharge machining can ensure the dimensional accuracy and shape accuracy of the positioning groove 2. Electric spark discharge machining is not limited by material hardness and shape, and can process various complex-shaped positioning grooves 2. Electric spark discharge machining can avoid thermal deformation and mechanical deformation of the material, thereby obtaining a smooth machining surface, improving the wear resistance and corrosion resistance of the clamp, and prolonging the service life of the clamp.

[0041] Further, the parallelism and perpendicularity of the positioning groove 2 are within 0.01 mm. The positioning groove 2 formed by electric spark discharge machining can ensure the size and accuracy of the positioning groove 2. In this embodiment, the parallelism and perpendicularity of the positioning groove 2 are within 0.01 mm, that is, the distance error between two adjacent side surfaces of the positioning groove 2 is not more than 0.01 mm, and the perpendicularity error of the positioning groove 2 and the bottom plate is not more than 0.01 mm. By setting the high-precision positioning groove 2, the position of the workpiece in the clamp can be ensured to be accurate, and the workpiece can be prevented from shifting or tilting, thereby ensuring the machining precision and product quality and reducing the scrap rate.

[0042] Further, the material of the clamp body 1 is spring steel. Spring steel is a high-carbon alloy steel with excellent elasticity, strength, wear resistance and fatigue resistance. Since the clamp body 1 is made of spring steel, when the clamp clamps the workpiece, it can deform greatly to clamp the workpiece, and when the workpiece is loosened, it can quickly return to the original shape, avoiding deformation or damage of the clamp. Further, since spring steel has good wear resistance, it can resist wear and scratches on the surface of the workpiece, ensuring the service life of the clamp, reducing the maintenance frequency of the clamp, and reducing maintenance costs. Further, since spring steel has excellent fatigue resistance, it can maintain good performance during repeated clamping and loosening of the workpiece, avoiding fatigue damage of the clamp, improving the service life of the clamp, and reducing the replacement frequency of the clamp.

[0043] The above only describes optional embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and drawings, or direct / indirect application in other related technical fields under the utility model concept of the utility model is included in the patent protection range of the utility model.
