[0002] In daily life or work, we often encounter situations where a box is needed for storage, and the box usually has a cover, which is connected to the box by a hinge. For example, the armrest box of a car is an item connected by a hinge. The torque of the hinge directly affects the force used by the user to open the cover, or whether it is laborious to open the cover, which is determined by the torque of the hinge. If the torque of the hinge is too large, it is easy for the user to open it with difficulty and it is inconvenient to use. If the torque is too small, it is easy for the cover to not hover or be unstable. Therefore, during the design and production of the hinge, it is often necessary to measure or calibrate its torque.
[0003] Generally, a torque measuring instrument is used to test whether the torque of the hinge meets the production requirements. During the test, the hinge is fixed to the measuring end of the torque measuring instrument through a torque test fixture, and then the male hinge or female hinge of the hinge is driven to rotate so that it overcomes the torque and rotates along the hinge pin of the hinge, so that the torque measuring instrument measures the corresponding torque value to observe whether the torque value meets the torque requirements.

DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] See also Figures 1 to 6 In an embodiment of the utility model, a jig for performing torque testing on a hinge includes:
[0033] The columnar assembly 10 is used to connect and assemble the entire jig, and can be installed on the test end of the external torque measuring instrument 54, so that the torque measuring instrument 54 can measure the torque applied to the columnar assembly 10;
[0034] A fixed base 20 is fixedly connected to the columnar assembly 10 and is used to carry and fix the first bracket 51 of the hinge 50;
[0035] Furthermore, the rotating base 40 is rotatably connected to the columnar assembly 10 to support and fix the second bracket 52 of the hinge 50 ; and is also used to drive the second bracket 52 to rotate a certain angle so that the torque measuring instrument 54 can measure the torque of the hinge 50 .
[0036] Specifically, the torque testing fixture of the hinge 50 of the utility model mainly fixes the fixture of the profiling product hinge 50 on the torque testing instrument, and combines the deep groove ball bearing with the thrust ball bearing. The rotation angle of the hinge 50 can be changed by pushing and pulling the rotating handle 44, so as to measure the torque of the hinge 50. At the same time, the adjusting nut on the pin 53 of the hinge 50 can be twisted with a wrench to adjust the torque of the hinge 50, and the torque can be quickly adjusted to the desired range.
[0037] Secondly, especially through the combination of deep groove ball bearings and thrust ball bearings, the fixture can produce good thrust effect and radial load effect, making the fixture more capable of withstanding vibration and impact, thereby improving the service life and reliability of the bearing. Deep groove ball bearings and thrust ball bearings can also be combined in different proportions according to specific requirements to meet different bearing load requirements.
[0038] Thirdly, the torque test fixture of hinge 50 of the utility model can be profiled on the fixture according to different shapes of products, so that the fixture and the product are integrated together, making the measurement value more accurate. That is, corresponding profiling grooves 22 can be set on the fixed base 20 according to different hinge 50 products, so that the hinge 50 product can be relatively smoothly and fit into the profiling groove 22, so that the fixed base 20 accurately limits one of the brackets of the hinge 50, so that the pin 53 of the hinge 50 and the measuring end of the torque measuring instrument 54 maintain an accurate coaxial setting, so that the measurement is more accurate. Moreover, it has a simple structure, is easy to operate and has strong practicality, which greatly improves work efficiency.
[0039] like Figure 4 As shown, preferably, the fixed base 20 is provided with an axial hole 21, and the axial hole 21 forms a coaxial arrangement with the columnar component 10. The axial hole 21 is used to accommodate one end of the pin shaft 53 of the hinge 50, and to form a coaxial arrangement between the pin shaft 53 of the hinge 50 and the columnar component 10.
[0040] Specifically, the shaft hole 21 is mainly provided to accommodate the pin shaft 53 of the hinge 50 and to avoid the nut of the fixed pin 13 shaft, so that the pin shaft 53 end of the hinge 50 can be stably placed on the fixed base 20, and the pin shaft 53 can be maintained coaxially with the columnar component 10, thereby making the torque test more accurate.
[0041] like Figures 3 to 6 As shown, preferably, the fixed base 20 is further provided with a contoured groove 22 , the inner shape of the contoured groove 22 is adapted to the support arm of the first bracket 51 of the hinge 50 , so that the support arm of the first bracket 51 of the hinge 50 can be embedded in the contoured groove 22 .
[0042] Specifically, the profiling groove 22 can be made according to the parameters such as the shape and size of the hinge 50 to be measured, so that the profiling groove 22 can just place the hinge 50, and can form a relatively perfect limiting effect on the hinge 50. The pin 53 and the measuring end of the torque measuring instrument 54 are accurately coaxially arranged. In addition, preferably, the non-corner part of the profiling groove 22 is avoided by 0.05mm on one side all around, and the corner is appropriately avoided according to the shape of the product to prevent the product from being damaged. The hinge 50 product can be better fixed on the fixture through the profiling groove 22, and the hinge 50 product can be better combined with the torque measuring instrument 54, so that the measured value is more accurate. Secondly, the fixed base 20 can also be provided with an avoidance groove 23, and the avoidance groove 23 is used to avoid the bending part of the second bracket 52 of the hinge 50.
[0043] like Figure 3 and Figure 4 As shown, preferably, the fixed base 20 is further provided with a support frame 30, and the support frame 30 is detachably fixed to the fixed base 20, and is used to form a support and limit function for the first bracket 51 of the hinge 50, so that the first bracket 51 is stably placed on the fixed base 20 and forms a fixed connection. The support frame 30 is provided with a plug-in boss 31, and the fixed base 20 is provided with a plug-in groove 24, and the plug-in boss 31 and the plug-in groove 24 cooperate with each other, so that the support frame 30 is detachably fixed to the fixed base 20.
[0044] Specifically, for different hinge 50 products, the shape or thickness of the first bracket 51 may be different. Therefore, in order to test different hinge 50 products, it is preferred to set the support frame 30 to be removable and replaceable. Preferably, the support frame 30 can be simply plugged into the fixed base 20 by the cooperation of the protrusion and the groove, and a fixed connection can be formed. In addition, in order to further fix the support frame 30, a threaded hole (not shown in the figure) can be set on the support frame 30, and a through hole is set on the fixed base 20, and the support frame 30 is fixedly connected to the fixed base 20 by bolts.
[0045] like Figures 2 to 4 As shown, preferably, the rotating base 40 is provided with a driving frame 41, the driving frame 41 is fixedly connected to the rotating base 40, and abuts against the second bracket 52 of the hinge 50, thereby driving the second bracket 52 to rotate a certain angle, so that the torque measuring instrument 54 can measure the torque of the hinge 50. The driving frame 41 is provided with a latch seat 42 and a latch plate 43, the latch seat 42 is fixedly connected to the driving frame 41, and the latch plate 43 is movably connected to the latch seat 42, and forms an abutment and limiting effect on the second bracket 52.
[0046] Specifically, the driving frame 41 and the rotating base 40 can also be fixedly connected by the connection method of the above-mentioned plug-in groove 24 and the plug-in boss 31, and similarly, bolts can be used for reinforcement.

The latch seat 42 can be fixed to the driving frame 41 by a fixed connection method such as mortise and tenon connection, and then a through hole is set at a suitable position of the latch seat 42 corresponding to the second bracket 52, and the latch plate 43 is inserted into the through hole, so that the latch plate 43 can limit the second bracket 52. In order to prevent the latch plate 43 from falling off, a long through hole can be set on the latch plate 43, and a limiting long rod 45 can be set on the latch seat 42, and the limiting long rod 45 is inserted into the long through hole to limit the latch plate 43 and prevent it from falling off.
[0047] like Figures 1 to 3 As shown, preferably, the rotating base 40 is also provided with a rotating handle 44, and the rotating handle 44 is fixedly connected to the rotating base 40 for applying a rotational torque to the rotating base 40, thereby driving the second bracket 52 to rotate a certain angle, so that the torque measuring instrument 54 can measure the torque of the hinge 50.
[0048] Specifically, in order to better apply rotational power to the rotating base 40, a rotating handle 44 can be preferably provided. By utilizing the lever principle and lengthening the rotating handle 44, the rotating base 40 can be relatively easily rotated, which is convenient for torque testing and also convenient for adjusting the torque of the hinge 50.
[0049] like Figures 4 to 6 As shown, preferably, the columnar component 10 is provided with a connecting shaft 11 and a first bearing 12, the first bearing 12 is sleeved on the connecting shaft 11, so that the inner ring of the first bearing 12 is fixedly connected to the connecting shaft 11, and the second bracket 52 is sleeved on the first bearing 12 and forms a fixed connection with the outer ring of the first bearing 12.
[0050] Specifically, the columnar component 10 is also provided with a fixing pin 13, one end of which is fixedly connected to the connecting shaft 11, and the other end of which is fixedly connected to the first bracket 51. That is, the first bracket 51 and the connecting shaft 11 can be keyed by the fixing pin 13, and of course, the first bracket 51 and the connecting shaft 11 can also be made into a fixed connection by other existing technologies. Preferably, the first bearing 12 can be set using a deep groove ball bearing in existing products. The deep groove ball bearing can withstand radial loads and combined radial and axial loads, which can make the fixture produce good thrust effect and radial load effect, making the fixture more capable of withstanding vibration and impact, thereby improving the service life and reliability of the fixture.

[0052] Specifically, the mounting portion 16 is used to mount the fixture on the test end of the external torque measuring instrument 54, and the mounting portion 16 and the connecting shaft 11 can be fixedly connected using existing technologies, such as key connection, or interference fit and other fixed connection methods. Preferably, the second bearing 14 can be set using a thrust ball bearing in existing products, and the thrust ball bearing can better withstand the axial load, so that the fixture can produce a good thrust effect and axial load effect, making the fixture more capable of withstanding vibration and impact, thereby improving the service life and reliability of the fixture.
[0053] When in use, the fixture can first be installed on the test end of the external torque measuring instrument 54 through the fixture mounting portion 16. The shape of the mounting portion 16 can be used to fit into the test end for fixed connection, or the fixture can be better fixed to the test end of the torque measuring instrument 54 through other fixed connection methods such as bolts.
[0054] Then, the hinge 50 to be measured is installed on the fixed base 20 of the jig, so that the side of one of the brackets of the hinge 50 is inserted into the profiling groove 22 and also inserted into the support frame 30, so that the hinge 50 can be accurately and firmly fixed on the fixed base 20 of the jig, and then the other bracket of the hinge 50 is placed on the driving frame 41 of the rotating base 40, and the bracket is fixed on the driving frame 41 by using the cooperation of the latch seat 42 and the latch plate 43.
[0055] Then, the rotating handle 44 can be rotated to apply a certain rotational force to the rotating base 40, so that it rotates a certain angle, and the hinge 50 rotates synchronously, thereby generating a certain torque, so that the torque measuring instrument 54 can test the corresponding torque size.
[0056] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
