[0039] Referring to Figure 1 and Figure 2 It is shown that the stretching sample tool 10 related to the embodiments of the present application has a first direction z, and the stretching sample tool 10 comprises a base 100, a gantry 200 and a clamping assembly 300.
[0040] Specifically, the base 100 is provided with a first fixing groove 110; the gantry 200 is connected to the base 100; the clamping assembly 300 is connected to the gantry 200 and is spaced apart from the base 100 along the first direction z, and the clamping assembly 300 is provided with a second fixing groove 310, the second fixing groove 310 is spaced apart from the first fixing groove 110 along the first direction z, and the opening of the second fixing groove 310 is arranged opposite to the opening of the first fixing groove 110.
[0041] It should be noted that the first direction z is Figure 1 the direction indicated by z.
[0042] In the stretching sample tool 10 of the present application, since the clamping assembly 300 fixed on the gantry 200 is spaced apart from the base 100 along the first direction z, the second fixing groove 310 of the clamping assembly 300 is spaced apart from the first fixing groove 110 on the base 100 along the first direction z, and the opening of the second fixing groove 310 is arranged opposite to the opening of the first fixing groove 110, therefore, the two ends of the well-bonded stretching sample 20 can be respectively placed in the first fixing groove 110 and the second fixing groove 310, so as to fix the stretching sample 20 by the base 100 and the clamping assembly 300, to facilitate subsequent baking of the stretching sample 20. During the baking process of the stretching sample 20, since the base 100 and the clamping assembly 300 respectively abut against the two ends of the stretching sample 20, therefore, each part of the stretching sample 20 along its axial direction will not be blocked by the stretching sample tool 10, thus, the baking uniformity and baking efficiency of the stretching sample 20 can be improved, to improve the manufacturing efficiency of the stretching sample 20.
[0043] Referring to Figure 2 and Figure 4As shown, the gantry 200 is provided with a connecting hole 210, the clamping assembly 300 includes a clamping piece 320, the clamping piece 320 is arranged in the connecting hole 210 and moves relative to the connecting hole 210 along the first direction z, and the second fixed groove 310 is arranged at one end of the clamping piece 320 along the first direction z and faces the first fixed groove 110, and the connecting hole 210, the first fixed groove 110 and the second fixed groove 310 are coaxially arranged.
[0044] Specifically, referring to Figure 5 As shown, in the embodiment, the standard specimen of the bonding strength test piece 21 is a circular piece with a diameter of 25 mm and a thickness of 6 mm, and the tensile test rod 22 is a cylindrical rod body with a diameter of 25 mm, and one tensile test rod 22 is bonded at each end of the bonding strength test piece 21 through adhesive. In order to ensure the accuracy of the tensile test results, it is necessary to ensure the coaxiality of the bonding strength test piece 21 and the tensile test rod 22.
[0045] In the embodiment, since the second fixed groove 310 is arranged at one end of the clamping piece 320 along the first direction z and faces the first fixed groove 110, the clamping piece 320 and the base 100 can be used to fix the tensile test sample 20. At the same time, since the clamping piece 320 is arranged in the connecting hole 210 and moves relative to the connecting hole 210 along the first direction z, when it is necessary to fix the tensile test sample 20, the clamping piece 320 can be moved along the first direction z towards the direction close to the first fixed groove 110, so that the tensile test sample 20 can be fixed in the second fixed groove 310 away from one end of the first fixed groove 110. In this way, the fixing of the tensile test sample 20 is realized. When it is necessary to remove the tensile test sample 20 from the tensile test sample fixture 10, the clamping piece 320 can be moved along the first direction z away from the first fixed groove 110, so that the tensile test sample 20 can be separated from the second fixed groove 310 away from one end of the first fixed groove 110, so as to remove the tensile test sample 20 from the tensile test sample fixture 10. Further, when the tensile test sample 20 is fixed, since the connecting hole 210, the first fixed groove 110 and the second fixed groove 310 are coaxially arranged, the coaxiality of the two ends of the fixed tensile test sample 20 can be ensured, so as to ensure the coaxiality of the tensile test sample 20 at all positions along the axial direction during the baking process, ensure the coaxiality of the bonding strength test piece 21 and the tensile test rod 22, and thus improve the production yield of the tensile test sample 20 and improve the accuracy of the tensile test results.
[0046] Referring to Figure 3 and Figure 4 As shown, the clamping assembly 300 further includes an elastic fastener 330, one end of the elastic fastener 330 is connected with the clamping piece 320, the other end of the elastic fastener 330 is connected with the gantry 200, and the elastic fastener 330 has elastic potential energy moving along the first direction z towards the first fixed groove 110.
[0047] In the embodiment, since one end of the elastic fastener 330 is connected with the clamping piece 320, the other end of the elastic fastener 330 is connected with the gantry 200, and the elastic fastener 330 has the elastic potential energy moving along the first direction z towards the first fixed slot 110, when the clamping piece 320 abuts against one end of the tensile sample 20 away from the base 100 along the first direction z, the elastic fastener 330 can provide the clamping piece 320 with the pushing force moving along the first direction z towards the first fixed slot 110, so as to improve the fixing effect of the clamping piece 320 on the tensile sample 20, so that the tensile sample 20 can be fixed between the clamping piece 320 and the base 100.
[0048] Continuing to refer to Figure 3 and Figure 4 , the clamping piece 320 includes a clamping portion 321 and a guide portion 322, the guide portion 322 is arranged extending along the first direction z and penetrates the connecting hole 210, the clamping portion 321 is connected at one end of the guide portion 322 close to the first fixed slot 110 along the first direction z, and the second fixed slot 310 is arranged on the clamping portion 321.
[0049] In the embodiment, since the guide portion 322 is arranged extending along the first direction z and penetrates the connecting hole 210, and the clamping portion 321 is connected at one end of the guide portion 322 close to the first fixed slot 110 along the first direction z, the movement of the guide portion 322 along the first direction z in the connecting hole 210 can drive the clamping portion 321 to move along the first direction z, so as to fix the tensile sample 20 away from one end of the first fixed slot 110 along the first direction z in the second fixed slot 310 on the clamping portion 321, or make the tensile sample 20 away from one end of the first fixed slot 110 along the first direction z from the second fixed slot 310 on the clamping portion 321.
[0050] Specifically, referring to Figure 3 , in the embodiment, the clamping piece 320 further includes a limiting portion 323, the limiting portion 323 is connected at one end of the guide portion 322 away from the clamping portion 321 along the first direction z and protrudes from the guide portion 322 along the radial direction of the guide portion 322, when the guide portion 322 moves along the first direction z towards the direction close to the first fixed slot 110, the limiting portion 323 can limit the guide portion 322, and the abutting of the limiting portion 323 and the gantry 200 can prevent the guide portion 322 from being separated from the connecting hole 210, and when the guide portion 322 moves along the first direction z, the worker can hold the limiting portion 323 to move the guide portion 322, so as to improve the convenience of the tensile sample 20 in the fixing process.
[0051] Referring to Figure 3As shown, the elastic fastener 330 is a spring, the clamping portion 321 protrudes from the guide portion 322 in the radial direction of the guide portion 322, the spring is sleeved on the guide portion 322, and one end of the spring abuts against the gantry 200, and the other end of the spring abuts against the part where the clamping portion 321 protrudes from the guide portion 322.
[0052] In the embodiment, when the tensile sample 20 is fixed in the second fixed slot 310 away from one end of the first fixed slot 110 along the first direction z, the tensile sample 20 will apply a tendency to the clamping portion 321 to move away from the first fixed slot 110 along the first direction z. Since one end of the spring abuts against the gantry 200, and the other end of the spring abuts against the part where the clamping portion 321 protrudes from the guide portion 322, when the clamping portion 321 has a tendency to move away from the first fixed slot 110 along the first direction z, the spring will be compressed, so that the spring has an elastic potential to drive the clamping portion 321 to move toward the first fixed slot 110 along the first direction z, thereby improving the stability of the connection between the clamping portion 321 and the tensile sample 20, so that the tensile sample 20 can be abutted between the first fixed slot 110 and the second fixed slot 310.
[0053] Specifically, in the embodiment, the guide portion 322 is coaxially arranged with the second fixed slot 310.
[0054] In the embodiment, since the guide portion 322 is coaxially arranged with the second fixed slot 310, when the spring applies a thrust to the clamping portion 321 to move toward the first fixed slot 110 along the first direction z, the force applied by the spring can be uniformly dispersed to the end of the tensile sample 20 away from the first fixed slot 110 along the first direction z, thereby improving the stress uniformity of the tensile sample 20, and ensuring the coaxiality of the bond strength test piece 21 and the tensile test bar 22.
[0055] Specifically, in the embodiment, the clamping portion 321 is detachably connected with the guide portion 322.
[0056] Specifically, in the embodiment, the clamping portion 321 is detachably connected with the guide portion 322 through a screw, and the screw connection can also improve the connection stability between the clamping portion 321 and the guide portion 322.
[0057] In the embodiment, since the clamping portion 321 is detachably connected with the guide portion 322, the clamping member 320 can be conveniently disassembled on the gantry 200, and the clamping portion 321 can be conveniently replaced, so that the clamping portion 321 can clamp tensile samples 20 of different sizes.
[0058] Referring to Figure 1 and Figure 2As shown, the tensile sample fixture 10 also has a second direction y, the second direction y is perpendicular to the first direction z, the gantry 200 has a plurality of gantries 200, the plurality of gantries 200 are spaced apart along the second direction y, each of the gantries 200 is connected with a clamping assembly 300, and the first fixing groove 110 has a plurality of first fixing grooves 110, each of the first fixing grooves 110 is spaced apart from a clamping assembly 300 along the first direction z.
[0059] It should be noted that the second direction y is Figure 1 the direction indicated in y.
[0060] In this embodiment, since each of the gantries 200 is connected with a clamping assembly 300, and each of the first fixing grooves 110 is spaced apart from a clamping assembly 300 along the first direction z, a plurality of tensile samples 20 can be fixed on the tensile sample fixture 10 at the same time, and a plurality of tensile samples 20 can be baked at the same time, thereby further improving the production efficiency of the tensile sample 20. Further, since the plurality of gantries 200 are spaced apart along the second direction y, the phenomenon of mutual interference or shielding between any two adjacent tensile samples 20 due to contact between them can be avoided, thereby improving the baking efficiency and baking effect of the tensile sample 20.
[0061] Continuing to refer to Figure 1 and Figure 2 As shown, the tensile sample fixture 10 also has a third direction x, the third direction x is perpendicular to the first direction z and the second direction y respectively, the gantry 200 extends along the third direction x, and each of the gantries 200 is connected with a plurality of clamping assemblies 300 spaced apart along the third direction x.
[0062] It should be noted that the third direction x is Figure 1 the direction indicated in x.
[0063] In this embodiment, since each of the gantries 200 is connected with a plurality of clamping assemblies 300 spaced apart along the third direction x, a plurality of tensile samples 20 can be fixed on the same gantry 200 at the same time, thereby further improving the number of tensile samples 20 that can be fixed by the tensile sample fixture 10 at the same time, thereby further improving the production efficiency of the tensile sample 20. Since the plurality of clamping assemblies 300 on each of the gantries 200 are spaced apart along the third direction x, the phenomenon of mutual interference or shielding between any two adjacent tensile samples 20 on each of the gantries 200 due to contact between them can be avoided, thereby improving the baking efficiency and baking effect of the tensile sample 20.
