DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0022] like Figures 1 to 4As shown, a bulk amorphous alloy mechanical property testing and polishing fixture includes a U-shaped base 101 and two sets of clamping plates 102 arranged on the U-shaped base 101 for clamping the bulk amorphous alloy, and also includes an elastic component arranged on the U-shaped base 101 for assisting the two sets of clamping plates 102 in clamping and positioning the bulk amorphous alloy. The two sets of clamping plates 102 are provided on opposite sides with a rolling component for assisting in adjusting the bulk amorphous alloy after positioning and a clamping component for clamping after adjustment. The upper end of the clamping plate 102 is provided with an identification component for identifying the clamping state.

[0023] Before testing the bulk amorphous alloy, the sample is cut according to the test requirements. Through the mutual cooperation of the elastic component, clamping component, transmission component and rolling component, it can not only ensure the stable clamping of the bulk amorphous alloy, but also perform fine-tuning of the bulk amorphous alloy during the clamping process, which facilitates the flexible clamping and grinding operations of the bulk amorphous alloy.

[0024] The elastic component includes multiple groups of T-shaped rods 201 slidingly connected to the U-shaped seat 101, one end of each group of T-shaped rods 201 is fixed to one side of the splint 102, and a spring 202 is sleeved on the outer side of each group of T-shaped rods 201, and the two ends of the spring 202 are respectively connected to the end of the T-shaped rod 201 and the outer side of the U-shaped seat 101; through the multiple groups of T-shaped rods 201, it is convenient to assist the movement guidance of the splint 102 after being subjected to force, and through the multiple springs 202, it is convenient to generate elastic force on the T-shaped rod 201 after movement.

[0025] The upper end of the splint 102 is provided with an inclined surface 3 for resisting and transmitting with the bulk amorphous alloy; the bulk amorphous alloy is pushed toward between the two sets of splints 102 of the U-shaped seat 101. During the pushing process, the two sides of the bulk amorphous alloy are respectively resisted against the inclined surfaces 3 on the two sets of splints 102. During the resisting process, the two sets of splints 102 are pushed to move away from each other under force.

[0026] The clamping assembly includes a mounting groove 501 opened on one side of the clamping plate 102, and a limiting plate 502 for clamping the bulk amorphous alloy is provided inside the mounting groove 501, and a transmission assembly for transmitting the limiting plate 502 is provided on the clamping plate 102; after the positioning and fine-tuning of the bulk amorphous alloy are completed, the limiting plates 502 inside the two sets of mounting grooves 501 are respectively abutted against the two sides of the positioned bulk amorphous alloy through the transmission assembly, so as to limit and clamp the positioned and fine-tuned bulk amorphous alloy.

[0027] The transmission assembly includes a threaded sleeve 601 fixed on the splint 102, and a threaded rod 602 is threadedly engaged with the threaded sleeve 601. One end of the threaded rod 602 is fixed to one side of the limit plate 502, and a driving pin 603 is fixed to the other end of the threaded rod 602. An avoidance groove 604 for avoiding the threaded rod 602 and the driving pin 603 is provided on the U-shaped seat 101; the threaded rod 602 is driven to rotate by the driving pin 603. During the rotation of the threaded rod 602, the limit plate 502 is moved by the mutual engagement transmission between the threaded rod 602 and the threaded sleeve 601.

[0028] The rolling assembly includes multiple groups of spherical grooves 701 opened on one side of the splint 102, and each group of spherical grooves 701 is connected to a ball 702 for rotation inside. After positioning, the bulk amorphous alloy is pushed. During the pushing process, the rotation of each group of balls 702 inside the spherical grooves 701 and the offsetting effect between the balls 702 and the bulk amorphous alloy facilitate the fine-tuning of the bulk amorphous alloy while maintaining the extrusion positioning of the bulk amorphous alloy.

[0029] The identification component includes a circular groove 401 opened at the upper end of the clamp 102, and a bubble level 402 is installed inside the circular groove 401; after the bulk amorphous alloy is limited and clamped, the bubble level 402 inside the circular groove 401 is used to facilitate the identification of the angle of the bulk amorphous alloy surface during the grinding process, which further facilitates the high-quality grinding of the bulk amorphous alloy.

[0030] Before testing the bulk amorphous alloy, the sample is cut to the required size and pushed between the two sets of clamping plates 102 of the U-shaped seat 101. During the pushing process, the two sides of the bulk amorphous alloy are respectively abutted against the inclined surfaces 3 on the two sets of clamping plates 102. During the abutment process, the two sets of clamping plates 102 are forced to move away from each other and contract.

[0031] After the bulk amorphous alloy is pushed between the two groups of clamping plates 102, the elastic force of the spring 202 on the elastic component and the connecting effect of the T-bar 201 force the two groups of clamping plates 102 to move closer to each other. During the movement, each group of balls 702 respectively abuts against the two sides of the bulk amorphous alloy to perform preliminary extrusion and positioning of the bulk amorphous alloy. After positioning, the bulk amorphous alloy is pushed. During the pushing process, the rotation of each group of balls 702 in the spherical groove 701 and the abutment between the balls 702 and the bulk amorphous alloy facilitate fine-tuning of the bulk amorphous alloy while maintaining the extrusion and positioning of the bulk amorphous alloy.

[0032] After the positioning and fine-tuning of the bulk amorphous alloy are completed, the transmission component is used to make the limit plates 502 inside the two sets of installation grooves 501 respectively abut against the two sides of the positioned bulk amorphous alloy, and the positioned and fine-tuned bulk amorphous alloy is limited and clamped, which is convenient for the subsequent more stable surface grinding treatment of the bulk amorphous alloy. After the bulk amorphous alloy is limited and clamped, the bubble level 402 inside the circular groove 401 is used to facilitate the identification of the angle of the bulk amorphous alloy surface grinding process, which further facilitates the high-quality grinding treatment of the bulk amorphous alloy.
