Detailed Description of the Embodiment

[0019] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 1 , Figure 2 shown, this embodiment discloses a tension pulley testing device, including a table board 1. Two vertical boards 2 are fixedly installed on the upper end surface of the table board 1. A slide rail 21 is installed on the inner side surface of the vertical board 2. The slide rail 21 is arranged in the vertical direction. A testing device 3 is installed between the two vertical boards 2. The testing device 3 can be lifted between the two vertical boards 2. The testing device 3 includes a moving frame 31, a motor 32, a connecting piece 33, a torque sensor 34, a connecting seat 35 and a pressing head 37. The moving frame 31 is slidably connected to the vertical board 2. Both sides of the moving frame 31 are slidably connected to the slide rail 21. By using the slide rail 21 for connection, compared with using a slide bar for connection, the noise is smaller and the movement stability is better.

[0021] More preferably, the vertical board 2 is provided with a notch 22. The notch 22 is located below the slide rail 21. The notch 22 can reduce the width of the lower end of the vertical board 2 and increase the operable area of the table board 1. The tension pulley 6 can be placed on the fixture 5 from the side.

[0022] The moving frame 31 includes a bottom board 311. A telescopic device 4 is installed on the bottom board 311. The bottom board 311 extends above the telescopic device 4. The upper end of the telescopic rod 41 of the telescopic device 4 is fixedly connected to the bottom board 311. The telescopic device 4 drives the moving frame 31 to lift. The telescopic device 4 is a telescopic rod 41 driven by a cylinder. Since the moving frame 31 is installed on the vertical board 2 through the slide rail 21, and since the telescopic device 4 is located behind the moving frame 31, the force applied when driving the moving frame 31 to move is biased to one side. Two sliding parts connected to the slide rail 21 are arranged on the side surface of the moving frame 31. The two sliding parts are distributed up and down and can eliminate the offset of the force applied by the telescopic device 4, and slide on the slide rail 21 more stably.

[0023] The motor 32 is fixedly installed on the moving frame 31. The moving frame 31 includes a top plate 312. The moving frame 31 is a rectangular frame with a hollow center as a whole. The motor 32 is fixedly installed on the top plate 312. The connecting member 33 and the torque sensor 34 are located between the top plate 312 and the bottom plate 311. Both ends of the torque sensor 34 are respectively connected to two connecting members 33. One of the connecting members 33 is connected to the motor 32, and the other connecting member 33 is connected to the connecting seat 35. The torque sensor 34 is a prior art and its principle will not be elaborated here. The lower end of the connecting seat 35 is rotatably connected to the pressing head 37. The lower end of the connecting seat 35 is installed with the pressing head 37 through a bearing. When the pressing head 37 presses down on the fixed tension pulley 6, the pressing head 37 will not rotate along with the connecting seat 35. The connecting seat 35 is installed on the bottom plate 311 through a bearing. The motor 32 can drive the connecting seat 35 to rotate. More preferably, a fixed mounting bushing 351 is installed on the lower end surface of the bottom plate 311. The bushing 351 is sleeved on the outer periphery of the connecting seat 35. The lower end of the bushing 351 is connected to the connecting seat 35 through a bearing. The upper end of the connecting seat 35 is connected to the bottom plate 311 through a bearing. The connecting seat 35 is also connected to the bushing 351 through a bearing. The two bearings are distributed at intervals and can stably support the connecting seat 35.

[0024] The connecting seat 35 includes a bracket 36. The bracket 36 is provided with a kidney-shaped hole 362. The dial rod 361 is installed on the bracket 36. The dial rod 361 can adjust the distance from the pressing head 37 along the kidney-shaped hole 362, and can be adjusted according to the different lengths of the baffle 61 of the tension pulley 6 to be tested, which is suitable for testing various different models of tension pulleys 6. The connecting seat 35 is fixedly installed with the dial rod 361. The dial rod 361 extends downward. The dial rod 361 can rotate together with the rotation of the connecting seat 35. After rotation, the dial rod 361 can contact the baffle 61 of the tension pulley 6 and overcome the tension force of the tension pulley 6 to push the baffle 61, so that the torque sensor 34 senses the torque of the tension pulley 6 and detects whether the torque of the tension pulley 6 meets the requirements. And no matter at what angle the baffle 61 is when the tension pulley 6 is placed on the fixture 5, the dial rod 361 can contact the baffle 61 after rotating a certain angle.

[0025] The fixture 5 is installed on the upper end surface of the table board 1. The upper end surface of the fixture 5 can place the tension pulley 6. The fixture 5 and the pressing head 37 are corresponding in the up and down positions. The fixture 5 is provided with concentric positioning for the tension pulley 6, so that when the tension pulley 6 is placed on the upper end surface of the fixture 5, it can be concentrically positioned with the fixture 5 and the pressing head 37.

[0026] As Figure 3 shown, this embodiment further includes an outer cover 7. The outer cover 7 is fixedly installed on the two vertical plates 2. The outer cover 7 can block the moving frame 31. The outer cover 7 is provided with two side connecting plates. The two side connecting plates are respectively fixed on the outer sides of the vertical plates 2. The outer cover 7 can play a role in beautification.

[0027] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
