However, the product needs to be directly inlaid after cutting, and the burrs need to be polished off with a grinder. The nitrided layer may collapse during polishing, and the inlay after grinding will affect the metallographic quality. Therefore, it is necessary to design a cutting fixture to make the product clamping more stable during cutting to avoid burrs. Utility Model Content

[0015] The following is a more detailed description of the implementation of the utility model in conjunction with the drawings and the figure marks, so that those skilled in the art can implement it after reading this specification. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0016] The utility model provides Figure 1-4 A cylindrical product 60 cutting fixture is shown, comprising a base 10, a support plate 11 is provided on one side of the base 10, and a telescopic rod 20 is provided on the other side, a pressing plate 21 is provided on one end of the telescopic rod 20 facing the support plate 11, and both the base 10 and the support plate 11 are provided with a feed groove 30. In the prior art, the base 10 and the support plate 11 are used to position the cylindrical product, and then the telescopic rod 20 located on one side of the feed groove 30 is used to press the cylindrical product and the support plate 11, and the cutting blade enters the feed groove 30 to cut the cylindrical product during cutting. Since the part of the cylindrical product located on the other side of the feed groove 30 is not clamped, when the cutting is about to be completed, due to the stress, the end of the cylindrical product that is not clamped is easy to break and produce burrs, and grinding the burrs will damage the nitride layer of the product, affecting the product quality. The telescopic rod 20 can refer to the relevant technology, and adopt an electric, hydraulic or pneumatic telescopic rod, and a dust box 22 is provided outside its driving device to prevent the debris generated by cutting from affecting the service life of the telescopic rod.
[0017] In order to solve the above-mentioned problem, the utility model also includes a pressing block 40 arranged between the telescopic rod 20 and the support plate 11, and the pressing block 40 is provided with a product positioning groove 41 and a feed groove 30 on the side facing the support plate 11, and the depth H1 of the feed groove of the pressing block 40 is greater than the depth H2 of the product positioning groove 41. The product positioning groove 41 extends along the length direction of the pressing block 40, and the feed groove 30 is perpendicular to the length direction of the pressing block 40. Specifically, the length direction of the pressing block 40 is parallel to the axial direction x1 of the cylindrical product 60; the feed groove of the pressing block 40 corresponds to the feed groove of the base 10 and the support plate 11, and the feed groove is a slit-shaped groove, and its center line x2 is perpendicular to the length direction of the pressing block 40. When in use, place the cylindrical product 60 in the product positioning groove 41, and then align the pressing block 40 and the cylindrical product 60 as follows. Figure 1-2The pressing block 40 is installed between the telescopic rod 20 and the support plate 11 in a manner, and then the telescopic rod 20 is used to press the pressing block 40 and the support plate 11, so that the parts of the cylindrical product 60 on both sides of the feed groove 30 are clamped, and the cylindrical product 60 is more stable during cutting to avoid the generation of burrs.
[0018] Preferably, the cross section of the product positioning groove 41 is an isosceles triangle, and the base of the isosceles triangle faces the support plate 11 to clamp cylindrical products of different diameters.
[0019] Preferably, a positioning plate 50 is rotatably connected to one side of the support plate 11, and a fastening nut 51 is threadedly connected to the rotation axis of the positioning plate 50. The positioning plate 50 positions the cylindrical product and the pressing block 40 from the end of the cylindrical product, which facilitates the installation of the pressing block and the fixed length cutting of the cylindrical product.
[0020] The above are one or more embodiments of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
