[0034] During the test, the positioning block 130 carries the handle, and the bending module and the self-rotation module of the handle can be respectively driven to act by the first traction mechanism 110 and the second traction mechanism 120, and the two modules can be tested simultaneously; and the detection sensor 140 performs non-contact detection on the position state information of the two modules to avoid the detection sensor 140 being worn and having a negative impact on the test data.

[0035] In this embodiment, the first direction is the horizontal direction, the second direction is the vertical direction, and the first direction is perpendicular to the second direction.

[0036] It should be noted that the core components of the bending module and the self-rotation module of the handle are both nitinol wires, and performing life tests on the two modules is actually performing life tests on the nitinol wires in the two modules.

The extension rod 113 is connected to the first slider 112, and the rotary joint 114 is disposed on the extension rod 113 and is used to connect to the bending module.

[0040] During the working process, the first slider 112 is used to move along the first guide rail 111, and at the same time drives the extension rod 113 and the rotary joint 114 to move, and drives the bending module to perform a bending action through the rotary joint 114.

[0041] Specifically, the extension rod 113 is cylindrical, one end of which is connected to the first slider 112, and the other end is connected to the rotary joint 114. The rotary joint 114 is a universal joint and is used to perform motion conversion between the extension rod 113 moving in a straight line and the bending module performing a bending action.

[0042] In addition, the first traction mechanism 110 may further include a first rotary driving member 115, a first support 116, and a first lead screw 117.

The first slider 112 is in screw engagement with the first lead screw 117, and the extending direction of the first lead screw 117 is the same as the first direction.

[0043] During operation, the first rotary driving member 115 can provide power to drive the first lead screw 117 to rotate relative to the first support 116, and the first slider 112 moves axially along the first lead screw 117 through the screw engagement between the first lead screw 117 and the first slider 112.

[0044] Reference Figure 2 , the second traction mechanism 120 includes a second guide rail 121, a second slider 122, and a third rotary driving member 126.

[0045] During the working process, the second slider 122 is used to move along the second guide rail 121, and at the same time drives the third rotary driving member 126 and moves. The third rotary driving member 126 is then used to drive the self-rotation module to perform a self-rotation action.

[0046] In addition, the second traction mechanism 120 may further include a second rotary driving member 123, a second support 124, and a second lead screw 125. The second rotary driving member 123 is in transmission cooperation with the second lead screw 125. The second lead screw 125 is rotatably disposed on the second support 124. The second slider 122 is in screw fit with the second lead screw 125. The extending direction of the second lead screw 125 is consistent with the second direction.

[0047] During operation, power can be provided by the second rotary driving member 123 to drive the second lead screw 125 to rotate relative to the second support 124. Through the screw fit between the second lead screw 125 and the second slider 122, the second slider 122 moves axially along the second lead screw 125.

[0048] It should be noted that the first rotary driving member 115, the second rotary driving member 123, and the third rotary driving member 126 can be a rotary motor, a rotary cylinder, or a rotary hydraulic cylinder, and the specific power form thereof is not limited.

[0049] Reference Figure 2 Referring to [reference], in order to facilitate the installation of the second traction mechanism 120, the handle life testing machine 100 may further include a suspension block 150. The bottom end of the suspension block 150 is disposed close to the positioning block 130. The second traction mechanism 120 is disposed at the top end of the suspension block 150.

[0050] Specifically, the suspension block 150 includes a support plate 151 and a reinforcing plate 152. The support plate 151 is L-shaped. The second traction mechanism 120 is disposed at the top end of one side of the support plate 151 and is connected to the support plate 151 by the second support 124 or the second guide rail 121. The reinforcing plate 152 is a right triangle structure and is disposed on the other side of the support plate 151. The two right-angled sides of the reinforcing plate 152 are respectively connected to the two L-shaped parts of the support plate 151, thereby playing a role in strengthening the structure of the support plate 151 and preventing the support plate 151 from tipping over due to carrying the second traction mechanism 120.

The detection sensor 140 is connected to the top end of the movable support block 160. The movable support block 160 is used to drive the detection sensor 140 to adjust its position.

[0052] Specifically, the movable support block 160 includes an adsorption block 161 and a movable link 162. The bottom end of the movable link 162 is rotatably connected to the adsorption block 161. The detection sensor 140 is connected to the top end of the movable link 162. That is, it can be fixed by adsorbing the adsorption block 161 on the installation frame. The movable link 162 is specifically a two-link structure, thereby driving the detection sensor 140 to adjust its position.

[0053] It should be noted that switches are provided on both the adsorption block 161 and the movable connecting rod 162, which are respectively used to adjust the adsorption intensity of the adsorption block 161 and unlock or lock the movable connecting rod 162.

[0054] In addition, in order to enable the test process to be automated, the handle life testing machine 100 may further include a controller, which may specifically be a PLC or a single-chip microcomputer. It is used to communicate with each rotation driving member and the detection sensor 140, and write a control program to realize intelligent control of the actions of each component. During the test process, the test time, the number of tests, the handle status information, etc. can also be recorded for subsequent data analysis and processing. When it is detected that the handle is damaged, the test will be stopped and an alarm signal will be sent to notify the staff to deal with it in time. The specific test method may include the following steps: Step 1, set the test parameters, which may specifically be the number of tests and the test speed, etc.; Step 2, install the handle on the positioning block 130, which is made of high-strength steel and is used to install the handle to ensure the position stability of the handle during the test; Step 3, control each rotation driving member to act in an orderly manner. During the action process, the position status information of the rotation module and the bending module of the detection sensor 140 is recorded and stored by the controller for various dynamic parameter information.

[0055] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
