In addition, in the present embodiment, the base mechanism 3 can also be used for receiving and collecting the liquid discharged by the dut 901 during the testing period, so as to perform other tests subsequently. Since the base mechanism 3 is of many types and is not the focus of the present invention, it is not detailed and is not limited to the drawings.
Referring to fig. 1, 2 and 4, the carrying mechanism 4 includes a rail unit 41 extending from left to right and erected on the base mechanism 3, a carrying seat 42 erected on the rail unit 41 and capable of sliding left and right and used for mounting the object 901, and an adjusting unit 43 installed and connected between the base mechanism 3 and the carrying seat 42. The guide rail unit 41 has two guide rails 411 extending in the left-right direction and parallel to each other at an interval in the up-down direction, and the carriage 42 is disposed so as to straddle the guide rails 411 in a manner to be slidable in the left-right direction.

The driver 432 is operable to drive the screw 431 to rotate around the self-axis relative to the carrying seat 42, so as to drive the carrying seat 42 to move and position along the longitudinal direction of the guide rail 411. Because there are many ways for driving the carriage 42 to move and position along the guide rail 411, the adjusting unit 43 is not limited to the above-mentioned transmission structure.

In addition, the mounting base 53 is provided with a liquid flow channel 530 extending from the left side surface to the right and inward, and bending and extending downward to be exposed at the bottom surface thereof, the liquid flow channel 530 can be used for receiving and guiding liquid released when the object 901 to be detected is pushed, such as lubricating oil, and the like, and can be used for guiding the guided liquid downward and dropping to the base mechanism 3. In other embodiments, when the sensor 902 is used to measure the characteristics of the liquid released from the dut 901, the structure of the liquid channel 530 of the mounting seat 53 can be changed, so that the mounting seat 53 can be used to guide the liquid to the sensor 902 for measurement. However, in practice, the mounting seat 53 may be changed according to the type of the sensor 902 used, and is not limited to the above embodiment.
In the present embodiment, the sensor 902 used in combination is a Load Cell (Load Cell) sensor, and the type of the sensor 902 is matched such that the mounting base 53 contacts to the left against the object 901 mounted on the bearing base 42, so that the sensor 902 can indirectly measure the specific mechanical characteristics of the object 901 through the mounting base 53. However, in other embodiments of the present invention, the mounting base 53 can be used to drive the sensor 902 to directly contact and abut against the object 901 for measuring the mechanical characteristics according to the type of the object 901 and the type of the mechanical characteristics to be sensed, for example, when sensing the oil temperature or the temperature of the object 901, the sensor can be used for mounting a temperature sensor; when sensing the oil pressure of the object 901, the oil pressure sensor can be installed.

However, since there are many ways to detect the distance change of an object, for example, an ultrasonic distance meter may be used instead, the type of the distance sensing unit 57 is not limited thereto, and the type of the distance measuring device 55 is not limited thereto. In addition, in practice, the distance measuring unit 55 is not necessary, so that the distance sensing unit 57 can directly detect the swing distance of the swing link 52.
The driving unit 56 includes a rotator 561 installed and fixed to the base mechanism 3, and an eccentric cam 563 eccentrically installed to a rotating shaft 562 of the rotator 561. The eccentric cam 563 is abutted to the end surface 543 of the pushing section 542 of the abutting convex rod 54 from the left side by the outer peripheral surface thereof, and is driven to rotate by the driver 561, so as to drive the abutting convex rod 54 to reciprocate from side to side, thereby driving the swing rod 52 to drive the sensor 902 to reciprocate from side to side relative to the object 901. In practice, a tachometer may be installed on the rotator 561 to measure the rotation speed of the rotator 561.
In the embodiment, the driver 561 is a motor, and the eccentric cam 563 is eccentrically installed on the rotating shaft 562 of the driver 561, but in other embodiments of the present invention, the driver 561 may also be a motor and a plurality of gears connected between the motor and the rotating shaft 562. Since the types of the driver 561 for driving the eccentric cam 563 to rotate are numerous and are not important to the improvement of the present invention, the detailed description thereof is omitted and the above embodiments are not limited thereto.
Referring to fig. 1, 3 and 6, the utility model discloses when mechanical testing machine 200 will detect the specific mechanical characteristic of this determinand 901 through this sensor 902, in installing this determinand 901 at this bearing seat 42, and install this sensor 902 behind this swinging unit 51's mount pad 53, operate driver 432 earlier in order to rotate this screw rod 431, this bearing seat 42 of transmission drives this determinand 901 and moves to the right, adjusts this determinand 901 to leaning on in this mount pad 53. Then, the driver 561 of the driving unit 56 can be activated to start the detection process.
In the detection process, the eccentric cam 563 is driven by the driver 561 to rotate, so as to drive the swing unit 51 to swing left and right reciprocally, so that the swing unit 51 drives the sensor 902 to move left and right reciprocally relative to the object 901, thereby changing the force of the mounting seat 53 contacting the object 901, and enabling the sensor 902 to continuously detect the specific mechanical property change of the object 901 during the left and right reciprocating movement. Meanwhile, the distance sensing unit 57 senses the displacement change of the distance measuring member 55, and directly measures the distance change of the driven swing of the swing link 52, so that the monitoring device can conveniently and synchronously analyze the relationship between the sensing result of the sensor 902 and the swing distance change of the swing link 52.
In practice, the length of the pushing section 542 of the abutting convex rod 54 protruding to the right from the free end 522 is adjusted to adjust the swing amplitude of the swing link 52 driven by the eccentric cam 563 to swing toward the object 901, thereby relatively increasing the force of the object 901 to be detected. In addition, the driver 432 can be operated to drive the screw 431 to drive the bearing seat 42 to move left and right relative to the swing rod 52, so as to change the contact force of the object 901 to be tested. Therefore, in practice, according to the structural types and testing requirements of various objects to be tested 901 and various sensors 902, the force of the objects to be tested 901 against by the mounting base 53 or the sensors 902 can be changed by adjusting the abutting convex rods 54 to the left or right, replacing the eccentric cams 563 with different outer diameters, and/or adjusting the carrying base 42 to the left or right relative to the swing rods 52.
Furthermore, in this embodiment, the carrying mechanism 4 and the measuring mechanism 5 are disposed in a left-right direction, the swing rod 52 is vertically and pivotally disposed on the base mechanism 3, and is between the left and right opposite sides of the object 901 to be measured and the rotator 561, and can be driven to swing in a left-right direction, so as to drive the sensor 902 to move left and right relative to the object 901 to detect the specific mechanical characteristics of the object 901. However, in another embodiment of the present invention, the bearing mechanism 4 and the measuring mechanism 5 can be configured in a vertical direction instead, that is, the whole mechanical testing machine 200 shown in fig. 3 is turned 90 degrees clockwise, so that the swing link 52 is extended left and right, the abutting convex rod 54 mounted on the swing link 52 is swung downward against the outer peripheral surface of the eccentric cam 563, the sensor 902 is located on the top side of the swing link 52, and the object 901 mounted on the bearing seat 42 is located above the sensor 902, so that the design can also drive the swing link 52 to drive the sensor 902 to reciprocate up and down relative to the object 901 through the rotation of the eccentric cam 563, so that the sensor 902 can detect the specific mechanical characteristics of the object 901.
In addition, in the present embodiment, the object 901 is installed on the bearing seat 42, and the sensor 902 is installed on the swinging unit 51, but in another implementation aspect of the present invention, the installation positions of the object 901 and the sensor 902 can be interchanged.
In summary, through the structural design of the swing unit 51 and the driving unit 56 of the testing mechanism 5, the eccentric cam 563 is driven to rotate to drive the swing rod 52 to drive the mounting seat 53 or the sensor 902 to push the object 901 to be tested in a reciprocating manner, so that the contact force between the mounting seat 53 or the sensor 902 and the object 901 to be tested is changed, and thus the change condition of the specific mechanical property of the object 901 can be detected, and when in use, the contact force sensing condition between the object 901 to be tested and the sensor 902 can be adjusted by adjusting the swing rod 42 closer or farther or by adjusting the swing amplitude of the swing unit 51 driven to swing towards the bearing seat 42 according to the structural style and testing requirements of the object 901 and the sensor 902, which is a very convenient and practical mechanical testing machine 200 design, can really achieve the purpose of cost utility model.
The above mentioned embodiments are only examples of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the contents of the patent specification are still included in the scope covered by the present invention.
