[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figures 1 to 9The present embodiment provides a coupling working condition test fixture, including a test platform 100, a servo motor 101 is provided at one end of the test platform 100, the servo motor 101 is connected to a driving shaft 101a, and a connecting rod 102 is provided at the other end of the test platform 100; a fixing mechanism 200, the fixing mechanism 200 includes a connecting bearing 201, a driven shaft 202 and a sleeve 203, the connecting bearing 201 is installed at the connecting rod 102, the driven shaft 202 and the connecting bearing 201 are connected, the sleeve 203 is installed at the ends of the driven shaft 202 and the driving shaft 101a, and the two sets of sleeves 203 are connected to the coupling 300.

[0030] The ends of the driving shaft 101a and the driven shaft 202 are both provided with threads, and the sleeve 203 is threadedly connected to the driving shaft 101a and the driven shaft 202. The threaded openings of the driving shaft 101a and the driven shaft 202 are both provided with first bolt holes 202b, and the outer wall of the sleeve 203 is provided with a second bolt hole 203a, and the second bolt hole 203a is connected with a fixing pin; the size of the sleeve 203 is adapted to the model of the coupling to be tested. When different models of couplings need to be tested, it is only necessary to replace different sleeves 203 to enable the test equipment to connect different models of couplings more stably.

[0031] A bearing inner disk 201a is rotatably connected inside the connecting bearing 201, and two groups of fixing rods 201b are fixedly connected to the inner wall of the bearing inner disk 201a. The interlayer between the two groups of fixing rods 201b is a slot 201c, and bolt slots 201d are penetrated through the tops of the two groups of fixing rods 201b. By clamping and fixing the driven shaft 202 inside the slot 201c, the driven shaft 202 can be fixed without affecting the rotation of the driven shaft 202, and the degree of axial deviation between the driven shaft 202 and the driving shaft 101a can be controlled by changing the position of the driven shaft 202 inside the slot 201c, thereby making the application range of the equipment wider.

[0032] There are two sets of connecting rods 102 and connecting bearings 201 in total, the purpose of which is to make the fixation of the driven shaft 202 more stable.

[0033] A plurality of groups 202a are provided at one end of the outer wall of the driven shaft 202. The driven shaft 202 is slidably connected inside the slots 201c of the two groups of bearing inner disks 201a and fixed by bolts. The plurality of groups 202a allow the driven shaft 202 to be adjusted to a horizontal distance from the driving shaft 101a. When a large-sized coupling is tested, the horizontal distance between the driven shaft 202 and the driving shaft 101a is adjusted according to the coupling model. Otherwise, a small-sized coupling is fixed and tested.

[0034] A clamping block 203b is provided on the outer wall of the sleeve 203, and a sliding groove is provided on the inner wall of the coupling 300. The clamping block 203b is slidably connected inside the sliding groove and fixed by a fixing bolt; the fixing bolt can be fixed by a bolt.

[0035] Working principle: When the coupling needs to be tested, select the sleeve 203 that is compatible with the model of the coupling 300 to be tested, thread the two sets of sleeves 203 to connect the active shaft 101a and one end of the driven shaft 202, and fix them with fixing bolts, then connect one end of the coupling 300 with the sleeve 203 at the active shaft 101a, and after completion, insert the driven shaft 202 into the slots 201c of the two sets of connecting bearings 201 in turn, and adjust the horizontal distance between the driven shaft 202 and the active shaft 101a according to the model of the coupling 300 to be tested by inserting the bolts into the bolt slots 201d and 202a in turn, and further adjust the distance of the axial deviation or the offset angle between the driven shaft 202 and the active shaft 101a freely through the two sets of connecting bearings 201. After completing the connection and fixing work, start the power supply and the servo motor 101 drives the active shaft 101a to rotate, and the active shaft 101a drives the sleeve 203 to rotate. Since the sleeve 203 and the active shaft 101a are fixed by a fixing bolt, the rotation of the sleeve 203 will not cause itself to rotate independently and fall off due to force. The sleeve 203 drives the coupling 300 to rotate, and the coupling 300 drives another set of sleeves 203, the driven shaft 202 and the connecting bearing 201 to rotate in turn, thereby feeding back the working state of the coupling 300 during operation; two sets of sleeves 203 connect the coupling 300, and the other set of sleeves 203 is connected to the driven shaft 202. By changing the connection state of the driven shaft 202 and the slot 201c inside the connecting bearing 201, the axial deviation angle and deviation distance between the two sets of shafts of the coupling 300 test device are changed, so that the equipment can adapt to more usage scenarios.
