[0002] Cladding technology is a metal material processing technology that forms a high-quality coating by placing metal powder or wire on the base material and using a heating source to melt and fuse it to the base material. Cladding technology is widely used in the fields of anti-corrosion coating, wear and abrasion resistance, precision component repair, thermal barrier coating and hybrid material preparation. It can provide additional protection, extend the service life of materials, improve the durability and life of parts, repair damaged precision parts, protect high-temperature working parts, and prepare multi-layer composite materials with specific properties. Cladding technology is widely used in industrial manufacturing, machinery repair and material protection by improving material properties and functions.

[0003] After the titanium alloy ball is clad, it is often necessary to conduct sampling inspection on the titanium alloy ball to test its hardness and friction performance to ensure that it meets the relevant requirements. However, most of the existing friction testing machines use fixed friction rollers to rub the titanium alloy balls. The rollers of different volumes, materials, and textures cannot be replaced for friction. At the same time, one side of the titanium alloy ball is always rubbed. This type of test has limitations and cannot simulate actual usage conditions. The experimental structure has limitations. Utility Model Content

[0006] Preferably, a titanium alloy ball is sleeved on the outside of the support structure, and the support structure comprises a central column connected to the fixed gear, and the upper end of the central column is connected to a fixing piece corresponding to the titanium alloy ball through a connecting groove.

[0007] Preferably, the side wall of the central column is provided with T-shaped grooves evenly distributed with the connecting groove as the center, and the interior of the groove is connected with a limiting piece corresponding to the groove through a plurality of evenly distributed first springs.

[0008] Preferably, the opening of the narrower end of the groove is connected to symmetrically distributed blocking members, and both sides of one end of the limiting member close to the groove are connected to limiting plates corresponding to the blocking members.

[0025] like Figure 1 and Figure 2 As shown, the utility model provides a friction testing machine for titanium alloy ball cladding, comprising a base 1, a support structure 2 located above the base 1 and connected by a fixed gear 11, a titanium alloy ball 15 is sleeved on the outside of the support structure 2, the support structure 2 comprises a center column 21 connected to the fixed gear 11, the upper end of the center column 21 is connected to a fixing piece 23 corresponding to the titanium alloy ball 15 through a connecting groove 22, one side of the support structure 2 is connected to a movable gear 13 through a transmission gear 12 corresponding to the fixed gear 11, a friction roller 14 is connected above the movable gear 13, a T-shaped groove 24 evenly distributed with the connecting groove 22 as the center is provided on the side wall of the center column 21, and a limit piece 26 corresponding to the groove 24 is connected to the inside of the groove 24 through a plurality of evenly distributed first springs 25.

[0026] In the present embodiment, a movable gear 13 with a friction roller 14 is arranged on the base 1. When a different friction roller 14 is replaced, the friction roller 4 drives the movable gear 13 to adaptively press against the ball to be tested, and is linked with the fixed gear 11 through the transmission gear 12. The fixed gear 11 drives the ball to be tested to rotate together with the support structure 2, and transmits the transmission to the movable gear 13 to drive the friction roller 14 to rotate, simulating the actual friction situation in use; the limit member 26 is pushed by the first spring 25, and the limit member 26 is pressed against the inner wall of the titanium alloy ball 15, thereby supporting the titanium alloy ball 15, and is inserted into the connecting groove 22 with the help of the fixing member 23 and tightened, so that the support structure 2 drives the titanium alloy ball 15 to rotate together.

[0027] like Figure 2 and Figure 3 As shown, a symmetrically distributed blocking member 27 is connected to the opening of the narrower end of the groove 24, and limiting plates 28 corresponding to the blocking member 27 are connected to both sides of one end of the limiting member 26 close to the groove 24, and a convex rotating column 16 is connected below the fixed gear 11, the movable gear 13 and the transmission gear 12, and one side of the rotating column 16 below the movable gear 13 and the transmission gear 12 is connected to a second spring 18 through a pushing member 17 corresponding to the rotating column 16, and a sliding groove 19 for accommodating the rotating column 16, the pushing member 17 and the second spring is provided on the base 1, and a motor placed inside the base 1 is connected to the side of the rotating column 16 below the fixed gear 11 facing away from the fixed gear 11.

[0028] In this embodiment, when the friction roller 14 is replaced, the friction roller 14 and the movable gear 13 are connected by means of a bolt structure or a mortise and tenon structure under the prior art, which is not limited in this article. When different friction rollers 14 are against the titanium alloy ball 15, due to the different spacings between them, the second spring 18 will be squeezed. After the movable gear 13 adjusts its position, it will squeeze the transmission gear 12 to adjust its position. With the help of the pusher 14 and the rotating column 16, the second spring 18 is squeezed in the sliding groove 19 and adaptively meshes with the fixed gear 11.

[0029] It should be noted that the position of the motor is not necessarily connected to the rotating column 16 located in the base 1 and below the fixed gear 11, but can also be placed outside and connected to the fixed gear 11, or can drive the transmission gear 12 or the movable gear 13, which should be determined according to the specific adaptation situation.

[0030] When in use, preparation work: fix the base 1 on the laboratory table or workbench, and install the motor inside the base. Ensure the stability and reliability of the friction testing machine; Support structure adjustment: replace the friction roller 14 as needed, and fix the new friction roller 14 on the movable gear 13. Connect through a bolt structure or a mortise and tenon structure, adjust the position of the movable gear 13 so that the friction roller 14 adapts to the sphere to be tested; Limit member setting: push the limit member 26 through the first spring 25, the limit member 26 supports the inner wall of the titanium alloy ball 15, and is inserted into the connecting groove 22 and tightened. Ensure that the support structure 2 can drive the titanium alloy ball 15 to rotate together; Blocking member and limit plate setting: according to Figure 2 and Figure 3 As shown, the blocking member 27 is connected to the opening at the narrower end of the groove 24, and the limit plate 28 is connected to both sides of the limit member 26; transmission system preparation: ensure that the fixed gear 11, the movable gear 13 and the transmission gear 12 are engaged normally, and adjust the position as needed; implement the test: according to specific needs and experimental requirements, drive the transmission gear 12 or the movable gear 13 by a motor or manually, so that the fixed gear 11 drives the titanium alloy ball 15 to rotate; at the same time, the friction roller 14 generates friction with the ball to be tested, and simulates the actual friction situation under the linkage of the fixed gear 11; result evaluation: according to the test conditions and actual conditions, observe and record the results of the friction test, and analyze the friction performance and wear characteristics of the material.
