[0038] Implementation Method 1

[0039] Please refer to Figures 1 to 4 As shown, a wire cutting fixture is provided in an embodiment of the present invention, which includes a tooling base 100 and a press-fitting assembly 200. The tooling base 100 includes a frame body 110, an accommodating channel 120 that penetrates the frame body 110 along a preset direction, and a limiting groove 130 that is arranged on the frame body 110 and connects the accommodating channel 120 with the external space. The accommodating channel 120 is used to accommodate the bolt head of the bolt 10, and the limiting groove 130 is used for the screw rod of the bolt 10 to pass through; the press-fitting assembly 200 includes at least one push rod 210 that is adjustably arranged on the frame body 110, one end of the push rod 210 is arranged in the accommodating channel 120 and facing the limiting groove 130, and the other end of the push rod 210 penetrates the frame body 110, and the push rod 210 is used to press on the bolt head of the bolt 10.

[0040] Overall, when the wire cutting fixture is used, the tooling base 100 is clamped by the caliper of the clamping device, and the bolt 10 to be cut is placed into the accommodating channel 120 from one end opening of the accommodating channel 120 on the frame body 110, so that the bolt head of the bolt 10 is placed in the accommodating channel 120 and the screw rod of the bolt 10 is placed in the limiting groove 130. The bolt 10 to be cut is fixed to the frame body 110 using the push rod 210 of the press-fitting assembly 200, and then the bolt 10 to be cut can be wire-cut to inspect the metallographic structure such as the thread profile of the bolt 10.

[0041] The present invention provides a locating channel 120 and a limiting groove 130 on the frame body 110 to limit the position of the bolt 10, allowing the frame body 110 to accommodate different types of bolts 10. Its simple and reliable structure, high versatility, and reduced equipment costs facilitate the rapid replacement of bolts 10 samples of different specifications. Furthermore, the present invention secures the bolt 10 through a crimping assembly, thereby improving its stability and preventing displacement of the bolt 10 during wire cutting, thereby enhancing cutting quality.

[0042] In the embodiment of the present invention, the preset direction is the length direction of the frame body 110, which is conducive to increasing the length of the accommodating channel 120 to meet the arrangement requirements of multiple bolts 10. The accommodating channel 120 has openings at both ends, so that the bolts 10 can be quickly placed into the accommodating channel 120.

[0043] In an embodiment of the present invention, at least one mounting through hole 140 is provided on the frame body 110 . The mounting through hole 140 is arranged facing the limiting groove 130 , and the push rod 210 is adjustably inserted into the mounting through hole 140 .

[0044] By setting a mounting through hole 140 on the frame body 110, the push rod 210 can pass through the mounting channel and abut against the bolt head of the bolt 10. The mounting channel can play a certain guiding and limiting role on the push rod 210, thereby improving the stability of the push rod 210 in use.

[0045] In a feasible embodiment, the push rod 210 is threadedly connected to the mounting through hole 140 , thereby facilitating adjustment of the position of the push rod 210 to better abut against the bolt 10 , thereby improving adjustment convenience.

[0046] Of course, in other feasible embodiments, designers can adjust the specific adjustment method of the push rod 210 according to usage needs, and no specific limitation is made here.

[0047] In the embodiment of the present utility model, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4In the illustrated embodiment, a plurality of mounting through holes 140 are provided, and the plurality of mounting through holes 140 are spaced apart along the extending direction of the limiting slot 130 , and a corresponding ejector rod 210 is provided in each mounting through hole 140 .

[0048] By providing a plurality of installation channels, a plurality of push rods 210 can be provided by utilizing a plurality of installation through holes 140 , thereby being able to fix a plurality of bolts 10 at the same time.

[0049] When multiple bolts 10 are simultaneously arranged on the frame body 110, the cooperation between the multiple push rods 210 and the limiting grooves 130 can clamp and limit the multiple bolts 10, and then the multiple bolts 10 can be cut simultaneously through one wire cutting, which significantly improves the sample preparation efficiency and improves the sample preparation quality.

[0050] The number and arrangement of the mounting holes 140 can be adjusted by the designer according to the use requirements, and no specific limitation is imposed here. Preferably, the plurality of mounting holes 140 are arranged at equal intervals.

[0051] In the embodiment of the present utility model, as Figure 1 、 Figure 2 and Figure 3 In the embodiment shown, the press-fitting assembly 200 also includes a positioning nut 220 and an elastic member 230. The positioning nut 220 is threadedly connected to the push rod 210 and abuts against the outer wall of the frame body 110. The elastic member 230 is arranged between the push rod 210 and the frame body 110. The elastic member 230 is used to provide clamping force for the push rod 210.

[0052] Specifically, the mounting hole 140 and the push rod 210 are not connected, so that the push rod 210 can be freely adjusted in the mounting hole 140. In addition, the positioning nut 220 and the elastic member 230 cooperate to fix the push rod 210 in the mounting hole 140, and the push rod 210 has a tendency to abut against the bolt 10, thereby improving the clamping stability of the bolt 10.

[0053] In addition, the operator can overcome the elastic effect of the elastic member 230 by pulling the other end of the push rod 210, so that the push rod 210 can be separated from the bolt 10, which makes it easy to remove the bolt 10, significantly improving the efficiency of removing the bolt 10; it is also easy to quickly fix the new bolt 10 to be cut on the frame body 110, significantly improving the efficiency of replacing the bolt 10.

[0054] In an embodiment of the present invention, the elastic member 230 includes a spring, which is sleeved on the top rod 210 and arranged in the accommodating channel 120. The spring can abut between one end of the top rod 210 and the inner wall of the frame body 110 to provide clamping force.

[0055] Of course, in other feasible embodiments, designers can adjust the specific shape, structure and setting method of the elastic member 230 according to usage requirements. For example, the elastic member 230 can be set as a disc spring, an elastic block or an elastic rope, etc., and no specific restrictions are made here.

[0056] In the embodiment of the present utility model, as Figure 4 In the illustrated embodiment, the accommodating channel 120 includes a relatively parallel upper end surface 121 and a lower end surface 122 , the mounting through hole 140 is provided on the lower end surface 122 , and the limiting groove 130 is provided on the upper end surface 121 .

[0057] By making the upper end face 121 and the lower end face 122 of the accommodating channel 120 parallel, the push rod 210 can abut against the bolt head of the bolt 10 vertically or approximately vertically, and one side end face of the bolt head of the bolt 10 can also abut against the upper end face 121 in parallel, thereby reducing or eliminating the angle between the push rod 210 and the bolt head of the bolt 10, so that surface contact can be formed between the push rod 210 and the bolt 10, which significantly improves the clamping stability.

[0058] In the embodiment of the present utility model, as Figure 1 、 Figure 2 and Figure 3 In the illustrated embodiment, from top to bottom, the limiting groove 130 includes a cylindrical section and a conical section connected to the cylindrical section, and the large end of the conical section is disposed on the upper end surface 121 .

[0059] By configuring at least a portion of the retaining groove 130 as a tapered section, the tapered section can better accommodate the bolt head of the bolt 10, thereby improving the versatility of the retaining groove 130 and meeting the positioning requirements of multiple-head bolts 10, such as hexagonal heads, flat head heads, and countersunk heads. Designers can adjust the taper and size of the tapered section according to actual needs, and no specific numerical value is imposed here.

[0060] In an embodiment of the present invention, a top block 211 is provided at one end of the push rod 210 , and the top block 211 is used to be pressed onto the bolt head of the bolt 10 .

[0061] By arranging the ejector block 211 on the ejector rod 210 , the ejector block 211 can provide a contact area with the bolt head of the bolt 10 , thereby improving the clamping stability.

[0062] Furthermore, when the elastic member 230 is a spring, the top block 211 can also limit the spring, thereby preventing the spring from separating from the top rod 210 .

[0063] The designer can adjust the specific shape of the top block 211 according to the use requirements, and no specific limitation is imposed here. Preferably, the top block 211 is configured as a column.

[0064] In an embodiment of the present invention, a clamping boss 150 is provided at the bottom of the frame body 110 , and the clamping boss 150 is symmetrically arranged with respect to the extending direction of the limiting groove 130 .

[0065] By setting a clamping boss 150 at the bottom of the frame body 110, the clamping boss 150 can better cooperate with the caliper of the clamping device, thereby improving the clamping stability of the frame body 110 and preventing the frame body 110 from moving during wire cutting and affecting the cutting effect of the bolt 10.

[0066] The specific shape and structure of the clamping boss 150 can be adjusted by the designer according to the actual use requirements and is not specifically limited here. Preferably, the clamping boss 150 is constructed in a rectangular parallelepiped shape. More preferably, the frame body 110 and the clamping boss 150 are integrally provided, thereby improving the structural strength between the frame body 110 and the clamping boss 150. When the clamping boss 150 is provided, the push rod 210 extends through the clamping boss 150.

[0068] An embodiment of the present invention provides a wire cutting clamping system, which includes a clamping device and the wire cutting fixture described in the first embodiment. The clamping device includes a caliper, and the caliper is used to clamp the wire cutting fixture.

[0069] The specific structure, working principle, and beneficial effects of the wire cutting fixture are the same as those in the first embodiment and will not be repeated here. By utilizing the wire cutting fixture described in the first embodiment, the wire cutting clamping system can simultaneously cut multiple bolts 10 with a single wire cutting operation, significantly improving sample preparation efficiency and quality.
