Description

Technical Field

[0001] The utility model belongs to the technical field of steel racket sample milling machines, and more specifically relates to a steel racket sample milling machine fixture. Background Art

[0002] Spectral analysis is a very important steel quality testing technology. By analyzing the elements in steel, it can accurately determine the composition and quality of steel. In the steel industry, spectral analysis technology has become an indispensable tool.

[0003] Due to the rapid pace of production and the high hardness of high-carbon steel, manual grinding of racket samples is no longer fast enough to meet the demands of real-world production. Consequently, equipment is used to mill the analysis surface of the racket specimens. However, the smoothness and flatness of the analysis surface seriously affect the analysis time and accuracy. Improving the milling fixture to improve the smoothness and flatness of the racket sample analysis surface has become urgent.

[0004] Currently, if Figure 1-3 As shown, the material of the milling sample fixture is 45 steel, the fixture bite surface is simple, and due to the presence of seams, pores, and different sizes of the racket sampler, there are raised edges and wings on the side of the racket sample, and the analysis surface diameters are different. The existing fixture cannot stably and firmly grasp the racket sample, resulting in an uneven milling sample analysis surface and the presence of ripples. Utility Model Content

[0009] Anti-slip grooves are arranged on the grooves.

[0010] Optionally, three clamping jaws are provided, and the three clamping jaws are distributed around the circumference.

[0011] Optionally, the anti-slip pattern is a plurality of tooth edges following the shape of the groove, and the tooth edges are arranged close to the rounded corner.

[0012] Optionally, the groove follows the shape of the racket sample.

[0030] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0031] like Figure 4-5 As shown, a steel racket sample milling prototype fixture includes:

[0032] The clamping end of the clamping jaw is a tapered structure, and the tip of the tapered structure is provided with an arc-shaped groove 6, and the two ends of the groove 6 are transitionally connected to the tapered structure through a rounded corner 7;

[0033] Grooves 8, which are arranged on the grooves 6 and are used to avoid the edges 2 and fins 3 of the racket sample 1;

[0034] Anti-slip grooves are provided on the grooves 6 .

[0035] Specifically, the axial end face of the sample 1 is the analysis surface 4, and the groove 8 accommodates the edge 2 and the fin 3 of the sample 1, so that the clamping jaws can be stably clamped on the flat surface of the sample 1, ensuring the stability of the clamping and reducing the obstruction and interference of the edge 2 and the fin 3.

[0036] In this embodiment, three clamping jaws are provided and distributed around the circumference.

[0037] Specifically, the three jaws are arranged in a T-shaped or Y-shaped configuration to ensure stable clamping while leaving space for the sample handle 5. Furthermore, the three jaws are spaced apart so that the oversized edges 2 and wings 3 can be moved into the gap between two adjacent jaws by rotating the sample 1.

[0038] In this embodiment, the anti-slip pattern is a plurality of tooth edges following the shape of the groove 6 , and the tooth edges are arranged close to the rounded corner 7 .

[0039] Specifically, the tooth edges prevent the sample 1 from rotating, thereby improving the clamping stability.

[0040] In this embodiment, the groove 6 follows the shape of the racket sample 1 .

[0041] Specifically, the clamping jaws are adapted to grooves 6 of different arcs according to the size of the sample 1 .

[0042] In this embodiment, the clamping jaws are 82 steel clamping jaws.

[0043] Specifically, the service life is increased by replacing 45 steel material with 82B material.

[0044] In this embodiment, the tapered structure is in a frustum shape.

[0045] Specifically, the frustum shape allows the side surfaces to avoid each other when clamped close together.

[0046] In this embodiment, the three clamping jaws and the sample handle 5 are evenly distributed around the circumference.

[0047] Specifically, the clamping jaws are arranged in a T-shape, forming a cross-shaped structure with the sample handle 5 .

[0048] In this embodiment, the groove 8 is provided in the middle of the recess 6 .

[0049] Specifically, the groove 8 is arranged in the middle so that the groove 6 is evenly stressed, and one clamping jaw is adapted to a sample 1 of one thickness.

[0050] In this embodiment, a plurality of grooves 8 are arranged in parallel at intervals.

[0051] Specifically, the edges 2 and wings 3 of the sample 1 are mostly at the waistline, and the multiple grooves 8 enable one clamping jaw to adapt to samples 1 of different thicknesses.

[0052] In this embodiment, the cross section of the groove 8 is rectangular or trapezoidal.

[0053] Specifically, the rectangular or trapezoidal cross section ensures that the interior of the groove 8 is not smaller than the exterior, thereby preventing the inner wall of the groove 8 from contacting the edge 2 and the fin 3 .

[0054] When the milling prototype clamp of a steel racket sample 1 of this embodiment is used, the three clamping jaws and the sample handle 5 are distributed in a circle. When clamping, the edges 2 and the wings 3 are avoided through the grooves 8, so that the grooves 6 can stably contact the circumference of the sample 1, thereby ensuring the stability of the clamping.

[0055] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
