DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 8 As shown, the utility model provides a multi-sample semi-automatic quantitative grinding fixture device, including a grinding and polishing machine body 1, a grinding head body 2 is arranged on the top of the grinding and polishing machine body 1, an adapter 3 is threadedly connected to the positioning end of the grinding head body 2, a threaded hole 4 is provided at the bottom of the adapter 3, a multi-sample fixture 5 is arranged at the bottom of the adapter 3, a mounting hole 6 is provided at the bottom of the multi-sample fixture 5, and the inside of the mounting hole 6 is threadedly connected to the threaded hole 4 through a screw, a locatable sample fixture 7 is arranged on the inner diameter of the multi-sample fixture 5, a rotating groove 8 is provided at the bottom of the locatable sample fixture 7, an outer cylinder 9 is threadedly connected to the inner part of the rotating groove 8, and the outer cylinder 9 is used in conjunction with the multi-sample fixture 5, a clamping groove 10 is provided at the bottom of the outer cylinder 9, and the inner diameter of the clamping groove 10 matches the sample diameter, and a leveling plate 11 is provided at the bottom of the multi-sample fixture 5.

[0025] refer to Figure 7 and Figure 8 A placement groove 12 is provided at the top of the leveling plate 11 , and a step ring 13 is provided at the top of the placement groove 12 .

[0026] As a technical optimization scheme of the utility model, by setting the placement groove 12 and the step ring 13, a layer of steps can be formed in the placement groove 12, the inner diameter of the bottom step is slightly smaller than the outer diameter of the multi-sample clamp 5, and the inner diameter of the upper step is slightly larger than the outer diameter of the multi-sample clamp 5, so that the multi-sample clamp 5 can be just suspended in the leveling plate 11, so that when multiple samples are placed, they can be supported by the placement groove 12, and then the multiple samples can be kept on the same horizontal plane.

[0027] refer to Figure 3 and Figure 6 A fool-proof groove 14 is provided at the top of the mounting hole 6 , and a fool-proof block 15 is fixedly connected to the bottom of the mounting hole 6 , and the fool-proof block 15 is snap-fitted with the fool-proof groove 14 .

[0028] As a technical optimization solution of the utility model, by setting the anti-idiot groove 14 and the anti-idiot block 15, preventive and corrective behavioral restraint means are used, and a restriction method to avoid errors is used, so that the operator does not need to spend attention, experience and professional knowledge to directly and accurately complete the correct insertion of the multi-sample clamp 5 into the bottom of the adapter 3.

[0029] refer to Figure 4 A micrometer 16 is provided on the surface of the positionable sample fixture 7 , and positioning holes 17 are provided on the surfaces of the positionable sample fixture 7 and the outer cylinder 9 , and the positioning holes 17 are used in conjunction with the micrometer 16 .

[0030] As a technical optimization scheme of the utility model, through the arrangement of the micrometer 16 and the positioning hole 17, there is a micrometer 16 that can be accurately positioned on the outer cylinder 9. Every time a certain scale is rotated, the sample can protrude a certain height, which is the height required for positioning and grinding. The outer cylinder 9 and the outer cylinder 9 of the positionable sample fixture 7 are matched through threads, so that the height change accuracy is 0.1mm. After adjusting to the required protruding grinding amount, it is then rotated into the positioning hole 17 through the top screw for fixation.

[0031] refer to Figure 2 The outer diameter of the outer cylinder 9 matches the inner diameter of the multi-sample fixture 5 .

[0032] As a technical optimization solution of the present invention, by arranging the outer diameter of the outer cylinder 9 to match the inner diameter of the multi-sample clamp 5, it is possible to avoid the situation where the diameter of the outer cylinder 9 is larger than the inner diameter of the multi-sample clamp 5, causing it to be unable to penetrate, thereby reducing the practicality of the outer cylinder 9.

[0033] refer to Figure 3 A plurality of top screws 18 are threadedly connected to the surface of the multi-sample clamp 5 , and the plurality of top screws 18 are in a one-to-one correspondence with the mounting openings on the surface of the multi-sample clamp 5 .

[0034] As a technical optimization solution of the present invention, by providing a plurality of top screws 18, the top screws 18 can be rotated to squeeze the positionable sample fixture 7, thereby achieving the effect of positioning it, thereby improving the stability of the positionable sample fixture 7 when in use.

[0035] The working principle and use process of the utility model are as follows: when the staff uses the multi-sample semi-automatic quantitative grinding fixture device, firstly, the sample is loaded into the clamping groove 10 of the outer cylinder 9 in the positionable sample fixture 7, and then the sample is threadedly connected with the positioning hole 17 on the outer cylinder 9 through the external top screw, so as to fix the sample. At this time, the positionable sample fixture 7 can be rotated, and the micrometer 16 scale on its surface is used as a reference, so that the sample protrudes a certain height (the height to be ground off) of the positionable sample fixture 7, and then the multi-sample fixture 5 is placed in the leveling plate 11, and then the sample and the positionable sample are fixed. The fixture 7 is placed as a whole in the multi-sample fixture 5. At this time, all samples are placed flat and all sample grinding surfaces are on the same plane. At this time, the top screw 18 is used to fix the positionable sample fixture 7. After completion, the leveling plate 11 is removed, and then the adapter 3 is installed on the multi-sample fixture 5 with the clamped samples, and then connected to the grinding head body 2 through the adapter 3. Finally, the grinding parameters are set and the grinding can be started. This can meet the needs of semi-automatic quantitative grinding of multiple samples at one time, and multiple samples can be positioned and ground to the specified position at the same time, thereby improving the grinding efficiency and stability (not affected by human factors).
