The working principle of device provided by the embodiment of the utility model is as follows:

A) Light deformation amount of the testing product in force environment

Test product 7 is installed to the workpiece position of the first platform 12, the shaft and center-pole 19 of test product 7 are fixed to be connected It connects, displacement sensor 8 is abutted with test product 7, set the value of pulling force or pressure on industrial personal computer later, industrial personal computer starting the Two motors 1, movable plate 14 is slided along guide post 13, if slide downward, the first lower block with center-pole 19 during the decline of shaft 5 Face contact then applies axial pressure to test product 7 by center-pole 19；If upward sliding, 5 uphill process of shaft Middle elder generation contacts with the upper retaining surface of center-pole 19, then applies axial pulling force to test product 7 by center-pole 19.It is set when reaching After fixed pulling force or pressure value, the second motor 1 stops, and displacement sensor 8 will test data and be uploaded to industrial personal computer at this time, by industry control The Light deformation amount of machine record test product 7.

B) starting torque of testing product

Test product 7 is installed to the workpiece position of the first platform 12, the shaft and center-pole 19 of test product 7 are fixed to be connected It connects, mobile shaft 5 makes the upper retaining surface of center-pole 19 and lower retaining surface not contact shaft 5, and adjustment displacement sensor 8 makes test product 7 do not contact with displacement sensor 8, and industrial personal computer starts first motor 17 later, and driving gear 20 gradually rotates, and pass through by Moving gear 6 applies torque to test product 7, and in the process, torque sensor 18 will test data and be uploaded to industrial personal computer, by work Control machine calculates the maximum torque and record of the process, the starting torque of the maximum torque, that is, test product 7.

By above-mentioned working principle it is found that device provided by the utility model not only can detecte the starting torque of product, but also can With the Light deformation amount of testing product, moreover, the device loads product by motor, it is poor to avoid manual operation bring Wrong or error.In conclusion device provided by the utility model has the function for detecting two indices data in the same device Can, and using the mode of mechanical load, therefore, help to improve the accurate of the efficiency and measurement result for detecting work Degree.

In the above-described embodiments, driving tooth is provided in the first transmission mechanism between first motor 17 and test product 7 Wheel 20, transmission shaft 15 and driven gear 6, transmission shaft 15 apply torsion moment to center-pole by driving gear 20 and driven gear 6 On 19, since center-pole 19 is fixedly connected with the shaft of test product 7, also just apply torsion moment on test product 7 simultaneously. In other examples, transmission shaft 15 can also directly be connect with the shaft of test product 7, so as to save driving tooth Wheel 20 and driven gear 6, certainly, in this case, the shaft and transmission shaft 15 of test product 7 should have one between each other Fixed surplus up and down along the vertical direction, counteracts to avoid the measurement to Light deformation amount.

In embodiment shown in Fig. 2, the structure of force transmission element is that the center of driven gear 6 passes through center-pole 19, by center-pole 19 lower end is connect with the shaft of test product 7, and in other examples, the first transmission mechanism can also have other to show shape Formula, can such as make following modification to the structure of force transmission element: center-pole 19 is only located at the side of driven gear 6 as connecting bushing, And be detachably connected with driven gear 6, and the other side of driven gear 6 and the shaft of test product 7 are detachably connected.It is changing the outfit When test product 7, first driven gear 6 is fixed on test product 7, after test product 7 is fixed on rack, then will be even Spindle set is fixed on driven gear 6.It is understood that should have for convenience of pressure and pressure, connecting bushing is provided Upper retaining surface and lower retaining surface are the activity space of 5 upper binding head of shaft between upper retaining surface and lower retaining surface.Implement with shown in Fig. 1 and Fig. 2 Example is the same, and when shaft 5 is movable, the connector on shaft 5 can realize the contact with the face of performing or lower retaining surface, to realize pulling force or pressure The application of power, meanwhile, the connector on shaft 5 also can be moved into neither with the face contact that performs, the also not position with lower block face contact It sets, so that the measurement for torque prepares.

In order to make torque Slow loading, can be set on the transmission shaft 15 between first motor 17 and driving gear 20 Set torsional spring.In order to make pressure Slow loading, spring 3 can be set between the nut 2 and movable plate 14 of leadscrew-nut mechanism. Pressure herein refers to pulling force or pressure.

In specific practical application, movable plate 14 is generally connect by linear bearing 4 with guide post 13.

As shown in Figure 1, mounting rack 11 is L shape, including vertical arm and horizontal arm in the present embodiment, displacement sensor 8 is installed In the end of horizontal arm, the upper end of vertical arm and the first platform 12 are hinged, and opposite first platform 12 of mounting rack 11 is around vertical arm Axis rotation.When needing the Light deformation amount of testing product, frame 11 is rotatablely installed by displacement sensor 8 and is sent to test product 7 Underface；When the starting torque of testing product, rotational installation frame 11 make displacement sensor 8 leave test product 7 just under Side.

In specific practical application, by the data box 9 for being used for installation data collector and it can be used to install concentratedly electrical connection The first layer of rack is arranged in the junction box 10 of device, and data collector should be with industrial personal computer, torque sensor 18 and displacement sensing Device 8 is electrically connected.

In addition, the power for applying first motor 17 is changed into test product 7 in specific embodiment shown in aforementioned First transmission mechanism of torque includes transmission shaft 15, driving gear 20 and driven gear 6, and the power that the second motor 1 is applied turns The second transmission mechanism for becoming 7 pressure of test product includes movable plate 14, shaft 5, guide post 13 and connecting bushing, and installation Frame 11 is L-type etc., but during specific implementation, and the utility model embodiment is disclosed to be used for testing product starting torque And the device of Light deformation amount can also have other specific manifestation forms.As the second transmission mechanism can behave as shaft and be located at axis The connection pawl of bar end, when needing to apply pressure, connection pawl is connected in the shaft of test product, and first motor 1 passes through Shaft and connection pawl apply pulling force or pressure to the shaft of test product；When needing to apply torque, connection pawl unclamps tested produce The shaft of product, in case the detection to torque affects.For another example, displacement sensor 8 can be flexibly connected with mounting rack 11, be come with this Realize that the position of displacement sensor 8 is adjustable.In short, as long as the first transmission mechanism can be realized the application of torque, the second driver Structure can be realized the application of pressure, and displacement sensor can both have been contacted by adjusting with test product, can also be with test product point It opens.

It should be noted that all the embodiments in this specification are described in a progressive manner, each embodiment it Between same and similar part may refer to each other, each embodiment focuses on the differences from other embodiments. Herein, relational terms such as first and second and the like are used merely to distinguish an entity with another entity Come, without necessarily requiring or implying between these entities, there are any this actual relationships.
