[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-2The present embodiment provides a technical solution: a transmission flexible shaft efficiency test device, comprising an aluminum profile 1, a spring compression box 2 is arranged on the upper side of one end of the aluminum profile 1, a compression spring 16 is arranged inside the spring compression box 2, a sliding screw 14 is passed through the inner side of the compression spring 16, a sliding nut 13 is arranged at one end of the sliding screw 14, a spring stopper 15 is arranged at the contact position between the inner side of the spring compression box 2 and the compression spring 16, a tension sensor 11 is arranged at one end of the sliding nut 13, and the tension sensor 11 is away from the sliding nut 13. A pull rod 12 is provided at the end, a replaceable hole sleeve 19 is provided on the pull rod 12, a fixed pin 21 is inserted on the replaceable hole sleeve 19, a travel pointer 17 is provided on the upper side of the replaceable hole sleeve 19, a scale 18 is provided on the side of the aluminum profile 1 corresponding to the position of the travel pointer 17, a screw rod 5 is provided on the inner side of the end of the aluminum profile 1 away from the compression spring 16, a screw connecting screw 4 is provided at one end of the screw rod 5, a screw nut 6 is passed through the screw rod 5, a fixed slider 7 is provided on the upper side of the screw nut 6, and a fixed buckle 9 is provided on the upper side of the fixed slider 7.

[0018] like Figure 1-2 As shown, the fixing buckle 9 can fix the transmission flexible shaft on the fixed slider 7, so that the other end of the transmission flexible shaft is connected to the replaceable hole sleeve 19 through the fixing pin 21, so that the test equipment can perform fixed testing on different models of transmission flexible shafts.

[0019] A screw fixing seat 8 is arranged at the other end of the screw 5 , a screw top plate 3 is arranged at one end of the screw connecting screw 4 , and a locking nut 10 is arranged at the connection position between the screw top plate 3 and the screw connecting screw 4 .

[0020] like Figure 1-2 As shown, the locking nut 10 can support the lead screw connecting screw 4. Rotating the lead screw connecting screw 4 can cause the lead screw 5 to rotate, thereby causing the fixed slider 7 to move laterally along the lead screw 5, thereby adjusting the distance between the fixed slider 7 and the tension sensor 11, so that the test equipment can test different models of transmission flexible shafts.

[0021] An anti-rotation guide groove 20 is provided at the contact position between the aluminum profile 1 and the fixed slide block 7. The aluminum profile 1 is connected to the screw top plate 3 via a locking nut 10, and the screw fixing seat 8 is connected to the aluminum profile 1 via bolts.

[0022] like Figure 1-2 As shown, the screw rod fixing seat 8 can rotatably support one end of the screw rod 5 so that the screw rod 5 can rotate stably, and the anti-rotation guide groove 20 can make the fixed slider 7 slide stably to prevent the fixed slider 7 from rotating around the screw rod 5.

[0023] The fixing buckle 9 is connected to the fixing slide block 7 by bolts, the tension sensor 11 is connected to the pull rod 12 by threads, and the pull rod 12 is connected to the replaceable hole sleeve 19 by nuts.

[0024] like Figure 1-2 As shown, the replaceable hole sleeve 19 is connected to the tension sensor 11 through the pull rod 12, so that when the transmission flexible shaft is subjected to force, the tension sensor 11 is deformed, and the tension or pressure of the transmission flexible shaft can be measured.

[0025] The replaceable hole sleeve 19 is crimped with the travel pointer 17 by bolts, and the fixed latch 21 is plugged with the transmission flexible shaft.

[0026] like Figure 1-2 As shown, the travel pointer 17 can move with the replaceable hole sleeve 19, and then indicate the deformation amount of the transmission flexible shaft after being stressed on the scale 18.

[0027] The aluminum profile 1 is glued to the scale 18 , and the transmission flexible shaft is connected to the fixed slider 7 via a fixed buckle 9 .

[0028] The fixed slide block 7 is slidably connected to the anti-rotation guide groove 20 .

[0029] The working principle of the transmission flexible shaft efficiency test device provided by the utility model is as follows: Figure 1-Figure 2 As shown, the transmission flexible shaft to be tested is fixed on the fixed slider 7, and the fixed buckle 9 is locked with a bolt to fix the transmission flexible shaft. The lead screw connecting screw 4 drives the lead screw 5 to rotate, so that the fixed slider 7 moves. According to the size of the fixed hole of the transmission flexible shaft, a suitable replaceable hole sleeve 19 is selected, and the fixed pin 21 is inserted. The fixed slider 7 moves to drive the pull rod 12 at the other end of the transmission flexible shaft to move, and the transmission flexible shaft is tested for push and pull force. When testing the thrust, the transmission flexible shaft extends to support the tension sensor 11. When the thrust exceeds the initial load of the compression spring 16, When the tension is tested, the compression spring 16 is compressed to prevent the tension sensor 11 from being overloaded. Data is calculated according to the scale of the travel pointer 17 and the specific numerical value of the display screen. When the tension is tested, the transmission flexible shaft retracts and pulls the tension sensor 11. When the tension exceeds the initial load of the compression spring 16, the compression spring 16 is extended and retracted to prevent the tension sensor 11 from being overloaded. Data is calculated according to the scale of the travel pointer 17 and the specific numerical value of the display screen. After the test, the transmission flexible shaft returns to its initial state, the fixing pin 21 is pulled out, the fixing buckle 9 is loosened, the transmission flexible shaft is removed, and the test is completed.
