[0035] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0036] Please refer to Figure 1 and Figure 4 As shown, the utility model designs a tension test fixture for a micro motor, which includes a tension gauge 5, and also includes a first mounting plate 1, a first connecting plate 2, a second mounting plate 3 and a second connecting plate 4 arranged in sequence along the vertical direction; wherein the tension gauge 5 is arranged on the second mounting plate 3, and one end of the tension gauge 5 is connected to the second connecting plate 4 through a spring 6; the first connecting plate 2 and the second connecting plate 4 are connected through a connecting rod 8, the first mounting plate 1 and the second mounting plate 3 are connected through a guide rod 7, and the first connecting plate 2 is sleeved on the guide rod 7 to slide along the extension direction of the guide rod 7.

[0037] It can be seen from the above description that in the present utility model, the inventor has optimized and designed a new tensile testing tool, which, by optimizing its own structure, can ensure that users can flexibly and conveniently apply the tensile testing tool to perform tensile tests on micro motors. Its rod-plate connection as an overall structure can bring about excellent effects such as small size, light weight, simple structure, and easy operation.

[0038] Based on the above settings, when the tensile testing tool is actually applied, the operator can set the micro motor 12 to be tested on the first mounting plate 1, and the operator can control the output shaft of the micro motor 12 to be tested to connect and match with the above-mentioned first connecting plate 2, so as to pull the first connecting plate 2 toward the first mounting plate 1 in the vertical direction through the micro motor 12 to be tested. At this time, since the first connecting plate 2 is sleeved on the guide rod 7, the first connecting plate 2 can approach the first mounting plate 1 along the extension direction of the guide rod 7.

[0039] Correspondingly, since the first connecting plate 2 and the second connecting plate 4 are specially connected together by the connecting rod 8 during the setting, the displacement of the first connecting plate 2 will also drive the second connecting plate 4 to move together, and make the second connecting plate 4 close to the second mounting plate 3. At this time, since the dynamometer 5 is arranged on the second mounting plate 3, and one end of the dynamometer 5 is connected to the second connecting plate 4 through the spring 6, the second connecting plate 4 approaches the second mounting plate 3, which will cause the distance between the second connecting plate 4 and the second mounting plate 3 to be reduced, thereby compressing the spring 6 arranged between the second connecting plate 4 and the second mounting plate 3, and causing the spring 6 to produce elastic deformation, thereby converting the pulling force of the micro motor into the elastic force of the spring 6, and finally being detected by the dynamometer 5 arranged on the second mounting plate 3.

[0040] Furthermore, the tensile testing tooling described in the present invention also includes a first pressure plate 9, which is arranged between the second mounting plate 3 and the second connecting plate 4, and the tensile gauge 5 is arranged between the second mounting plate 3 and the first pressure plate 9, and the spring 6 is arranged between the first pressure plate 9 and the second connecting plate 4.

[0041] Furthermore, in the tensile testing fixture described in the present invention, one end of the connecting rod 8 is connected to the first connecting plate 2 , and the other end of the connecting rod 8 passes through the first pressure plate 9 and is connected to the second connecting plate 4 .

[0042] In the above technical solution of the utility model, in order to ensure that the detection effect of the dynamometer 5 is more accurate, more reliable, and the user experience is better, in actual application, a first pressure plate 9 can also be provided, and the dynamometer 5 is provided between the second mounting plate 3 and the first pressure plate 9, and the spring 6 can be correspondingly provided between the first pressure plate 9 and the second connecting plate 4. When the second connecting plate 4 and the first connecting plate 2 move under the pull of the micro motor to be detected, the spring 6 will produce elastic deformation between the first pressure plate 9 and the second mounting plate 3, so as to convert the pulling force of the micro motor to be detected into the elastic force of the spring 6, and then use the first pressure plate 9 acting on the dynamometer 5 to transmit the elastic force of the spring 6 to the dynamometer 5, and then read the reading from the dynamometer 5.

[0043] Furthermore, the tensile testing fixture described in the present invention also includes an adjusting component 10, which includes a second pressure plate 101, a spring guide rod 102 and an adjusting screw 103. The second pressure plate 101 is arranged between the first pressure plate 9 and the second connecting plate 4, one end of the spring guide rod 102 is connected to the first pressure plate 9, and the other end of the spring guide rod 102 passes through the second pressure plate 101 and the second connecting plate 4 in sequence, and the spring 6 is sleeved on the spring guide rod 102 so that one end of the spring 6 is in contact with the upper surface of the first pressure plate 9, and the other end of the spring 6 is in contact with the lower surface of the second pressure plate 101; wherein the adjusting screw 103 is threadedly connected to the second connecting plate 4, and one end of the adjusting screw 103 extends from the second connecting plate 4 and is in contact with the upper surface of the second pressure plate 101.

[0044] In the above technical solution of the utility model, in certain specific implementations, in order to meet the testing requirements in different application situations and facilitate users to adjust the upper limit of the tensile force of the tensile testing tool, an adjustment component 10 can also be provided in actual application.

[0045] When the adjustment assembly 10 is actually used, the operator can control the adjustment screw 103 to rotate relative to the second connecting plate 4, so as to adjust the extension length of the adjustment screw 103 from the second connecting plate 4, thereby changing the distance between the second pressure plate 101 and the first pressure plate 9 that is in contact with one end of the adjustment screw 103. In the above technical solution, since one end of the spring 6 is in contact with the upper surface of the first pressure plate 9 and the other end of the spring 6 is in contact with the lower surface of the second pressure plate 101, the adjustment of the distance between the first pressure plate 9 and the second pressure plate 101 will directly affect the initial elastic deformation of the spring 6 sleeved on the spring guide rod 102.

[0046] Therefore, the operator can adjust the initial elastic deformation of the spring 6 so that when the tension of the micro motor 12 to be tested is subsequently tested, more measurable tension ranges can be covered, thereby facilitating the adjustment of the tension test fixture's own upper limit of tension measurement.

[0047] Furthermore, in the tension testing tool described in the present invention, the guide rod 7, the connecting rod 8 and the spring guide rod 102 all extend in the vertical direction.

[0048] Furthermore, in the tensile testing tool described in the present invention, the adjustment assembly 10 also includes a handle 104 , and the handle 104 is disposed on the adjustment screw 103 .

[0049] In the above technical solution of the utility model, in order to facilitate the user to control the adjustment screw 103 to rotate relative to the second connecting plate 4, in actual application, a handle 104 can also be set on the adjustment screw 103. The user only needs to hold the handle 104 with his hand to control the rotation of the adjustment screw 103, thereby adjusting the distance between the first pressure plate 9 and the second pressure plate 101.

[0050] Furthermore, in the tensile testing fixture described in the present invention, a connector 21 is provided on the first connecting plate 2, and the connector 21 is used to connect the output shaft of the micro motor to be tested.

[0051] Furthermore, in the tensile testing fixture described in the utility model, a guide hole is opened on the first connecting plate 2, a rotating shaft 22 is arranged in the guide hole, and the guide rod 7 is arranged to pass through the rotating shaft 22 along the vertical direction.

[0052] In the above technical solution of the utility model, in order to facilitate the pulling force of the micro motor 12 to be tested to effectively drive the first connecting plate 2 to move in the vertical direction, in actual application, a guide hole can also be opened on the first connecting plate 2, and a rotating shaft 22 is set in the above guide hole so that the guide rod 7 is set through the rotating shaft 22 in the vertical direction.

[0053] Furthermore, in the tensile testing tooling described in the present invention, the tensile gauge 5 is fixedly connected to the second mounting plate 3 and the first pressure plate 9 respectively, and one end of the tensile gauge 5 is in conflict with the upper surface of the second mounting plate 3, and the other end of the tensile gauge 5 is in conflict with the lower surface of the first pressure plate 9.

[0054] Furthermore, the tensile testing fixture of the present invention further includes a support plate 11 , which is fixedly connected to the first mounting plate 1 and is used to support the first mounting plate 1 .

[0055] Embodiment 1:

[0056] Please refer to Figure 1-Figure 4 As shown, the first embodiment of the utility model is: a tension testing fixture, which includes a tension gauge 5 and a first mounting plate 1, a first connecting plate 2, a second mounting plate 3, a first pressure plate 9 and a second connecting plate 4 arranged in sequence along the vertical direction; wherein the first mounting plate 1, the first connecting plate 2, the second mounting plate 3, the first pressure plate 9 and the second connecting plate 4 are all arranged horizontally, and the tension gauge 5 is arranged between the second mounting plate 3 and the first pressure plate 9, the tension gauge 5 is fixedly connected to the second mounting plate 3 and the first pressure plate 9 respectively, one end of the tension gauge 5 is in conflict with the upper surface of the second mounting plate 3, and the other end of the tension gauge 5 is in conflict with the lower surface of the first pressure plate 9.

[0057] like Figure 1 As shown, in this embodiment, the first connecting plate 2 and the second connecting plate 4 are connected by four connecting rods 8, and one end of the four connecting rods 8 is connected to the first connecting plate 2, and the other ends of the four connecting rods 8 pass through the first pressure plate 9 and are connected to the second connecting plate 4; at the same time, the first mounting plate 1 and the second mounting plate 3 are specifically connected by two guide rods 7, and the first connecting plate 2 is sleeved on the two guide rods 7 to slide along the extension direction of the two guide rods 7. Among them, the four connecting rods 8 and the two guide rods 7 extend in the vertical direction.

[0058] Further reading Figure 1 and Figure 2 It can be seen that in this embodiment, a spring 6 and an adjustment assembly 10 are further arranged between the first pressure plate 9 and the second connecting plate 4 .

[0059] In this embodiment, the adjustment assembly 10 specifically includes: a second pressure plate 101, an adjusting screw 103 and two spring guide rods 102 extending in the vertical direction. The second pressure plate 101 is arranged between the first pressure plate 9 and the second connecting plate 4. One end of the two spring guide rods 102 is connected to the first pressure plate 9, and the other end of the two spring guide rods 102 passes through the second pressure plate 101 and the second connecting plate 4 in sequence, and a linear bearing can be set in the hole opened on the second connecting plate 4 for the spring guide rods 102 to pass through.

[0060] At the same time, in the present embodiment, the above-mentioned spring 6 is sleeved on the spring guide rod 102 so that one end of the spring 6 contacts the upper surface of the first pressure plate 9, and the other end of the spring 6 contacts the lower surface of the second pressure plate 101; wherein, in the present embodiment, the above-mentioned adjusting screw 103 is provided with a handle 104, and the adjusting screw 103 is threadedly connected to the second connecting plate 4, one end of the adjusting screw 103 passes through the above-mentioned second connecting plate 4, and extends from the second connecting plate 4 to contact the upper surface of the second pressure plate 101.

[0061] It should be noted that, in the present embodiment, a connector 21 is provided on the first connecting plate 2, and the connector 21 can be used to connect the output shaft of the micro motor to be tested which is arranged on the first mounting plate 1; at the same time, in order to facilitate the first connecting plate 2 to slide along the guide rod 7, two guide holes are also provided on the first connecting plate 2, and a rotating shaft 22 for matching with the guide rod 7 is provided in the two guide holes, and the rotating shaft 22 can be specifically a flange rotating shaft, so that the two guide rods 7 can be respectively arranged through the rotating shaft 22 in the vertical direction.

[0062] Meanwhile, in order to support the first mounting plate 1 , two supporting plates 11 are further provided in the present embodiment. The two supporting plates 11 are both fixedly connected to the first mounting plate 1 to support the first mounting plate 1 .

[0063] For ease of understanding, the inventor further explains the actual application process of the tensile testing tool of this embodiment:

[0064] When actually applying the tensile testing tooling of this embodiment, the operator can set the micro motor 12 to be tested on the first mounting plate 1, and the operator can control the output shaft of the micro motor 12 to be tested to connect with the connecting head 21 of the above-mentioned first connecting plate 2, so as to pull the first connecting plate 2 toward the first mounting plate 1 along the vertical direction through the micro motor 12 to be tested. At this time, since the first connecting plate 2 is sleeved on the guide rod 7, the first connecting plate 2 can approach the first mounting plate 1 along the extension direction of the guide rod 7.

[0065] Correspondingly, since the first connecting plate 2 and the second connecting plate 4 are specially connected together by the connecting rod 8 during the setting, the displacement of the first connecting plate 2 will also drive the second connecting plate 4 to move together, and make the second connecting plate 4 close to the second mounting plate 3. At this time, the second connecting plate 4 will drive the second pressure plate 101 in the adjustment assembly 10 to approach the direction of the first pressure plate 9 along the extension direction of its own spring guide rod 102.

[0066] Since the above-mentioned spring 6 is sleeved on the spring guide rod 102 of the adjusting assembly 10, and one end of the spring 6 is in conflict with the first pressure plate 9, and the other end of the spring 6 is in conflict with the second pressure plate 101, when the second pressure plate 101 is close to the first pressure plate 9, the distance between the first pressure plate 9 and the second pressure plate 101 will be reduced, thereby compressing the spring 6 arranged between the first pressure plate 9 and the second pressure plate 101, and causing the spring 6 to produce elastic deformation, thereby converting the pulling force of the micro motor into the elastic force of the spring 6, and the elastic force of the spring 6 can be transmitted to the first pressure plate 9, and finally detected by the dynamometer 5 arranged between the second mounting plate 3 and the first pressure plate 9.

[0067] It should be noted that, when the above-mentioned adjustment assembly 10 is actually used, the operator can control the adjustment screw 103 to rotate relative to the second connecting plate 4, so as to adjust the extension length of the above-mentioned adjustment screw 103 from the second connecting plate 4, thereby changing the distance between the second pressure plate 101 that is in contact with one end of the adjustment screw 103 and the first pressure plate 9. In the above-mentioned technical solution, the adjustment of the distance between the first pressure plate 9 and the second pressure plate 101 will directly affect the initial elastic deformation of the spring 6 sleeved on the spring guide rod 102.

[0068] Therefore, the operator can adjust the initial elastic deformation of the spring 6 so that when the tension of the micro motor 12 to be tested is subsequently tested, more measurable tension ranges can be covered, thereby facilitating the adjustment of the tension test fixture's own upper limit of tension measurement.

[0069] Accordingly, in this embodiment, in order to ensure the accuracy of force transmission, during the actual installation and setting, the output shaft of the micromotor to be tested, the installation position of the connector 21, and the dynamometer 5 can be on the same vertical axis; the finished tooling prepared using this embodiment is about 50 cm high and 25 cm wide as a whole. It is mainly composed of rods and metal plates, with a small overall size and light weight, which is convenient for movement and storage.

[0070] In summary, the tension testing tool provided by the utility model can effectively test the tension of the micro motor by optimizing its own structure, and in some preferred embodiments, the user can also adjust the upper limit of the tension measurement of the tension testing tool to meet the testing requirements in different application situations; and the tension testing tool designed by the utility model specifically uses a rod-plate connection as an overall structure, which can bring excellent effects such as small size, light weight, simple structure, and easy operation.

[0071] Therefore, the tensile testing tool of the utility model can be effectively applied to the tensile testing of micro motors while reducing its own structural volume. It is easy to use and has good promotion prospects and application value.
