DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The present application embodiment discloses a roller loading test device. Figure 1 and Figure 2 The testing device includes a frame 1, a testing module 2 installed on the frame 1, and a positioning module 3 installed on the frame 1. The testing module 2 is used to test the test piece 100 (i.e., the electric roller), and the positioning module 3 is used to position the test piece 100 during the test.

[0036] Reference Figure 2 and Figure 3 The test module 2 includes two clamping rollers 21 slidably mounted on the frame 1, a test roller 22 rotatably mounted on the frame 1, and a conveyor belt 23 connecting the clamping roller 21 and the test roller 22. The test roller 22 is located below the two clamping rollers 21, and the axes of the clamping roller 21 and the test roller 22 are parallel to each other. The space between the two clamping rollers 21 forms a storage space for placing the test piece 100. When the test piece 100 is placed on the upper surface of the conveyor belt 23 between the two clamping rollers 21, the clamping rollers 21 approach each other and abut against the surface of the test piece 100. When the test piece 100 rotates, the test roller 22 can be synchronously driven to rotate through the conveyor belt 23. A tester 4 connected to the test roller 22 is installed on the frame 1. The tester 4 is a torque tester and can be equipped with a reducer during use. When the test piece 100 drives the test roller 22 to rotate, the tester 4 starts to collect various data such as torque and current. The torque of the test piece 100 can be obtained through conversion and whether the electric roller is qualified can also be judged.

[0037] Furthermore, in order to improve the transmission effect of the conveyor belt 23, two abutting rollers 16 are rotatably mounted on the frame 1, and the two abutting rollers 16 are located above the test roller 22 and below the clamping roller 21, and the distance between the two abutting rollers 16 is smaller than the distance between the two clamping rollers 21. The conveyor belt 23 passes between the two abutting rollers 16, and the abutting rollers 16 abut against the outer wall of the conveyor belt 23, thereby increasing the tension of the conveyor belt 23.

[0038] Reference Figure 2 and Figure 3 , both ends of the clamping roller 21 are equipped with a first sliding part 5, and the end of the clamping roller 21 is connected to the first sliding part 5 through a bearing seat. A second sliding part 6 is installed on the frame 1, and the first sliding part 5 and the second sliding part 6 can cooperate to form a sliding connection. Among the first sliding part 5 and the second sliding part 6, one is a slide rail, and the other is a slide seat that cooperates with the slide rail. The cross-section of the slide rail is a dovetail structure or a T-shaped structure, and the slide seat cooperates with the slide rail. In this embodiment, the first sliding part 5 is a slide rail, the second sliding part 6 is a slide seat, the clamping roller 21 is fixed to the upper surface of the slide rail through a bearing seat, and the lower surface of the slide rail is slidably connected to the slide seat. In order to facilitate the sliding of the clamping roller 21, the clamping roller 21 can be driven to slide by a cylinder or a screw that can realize a linear driving device. In addition, the clamping roller 21 can also be pushed to move manually, and after the slide rail and the slide seat slide, the slide rail is positioned by bolt locking.

[0039] Reference Figure 2 and Figure 4 There are two positioning modules 3, which are symmetrically located at the two ends of the test piece 100. When the test piece 100 is placed between the clamping rollers 21, the positioning modules 3 position the two ends of the test piece 100, so that the test piece 100 is not easily offset during the test.

[0040] The positioning module 3 includes an adjustment seat 31 slidably mounted on the frame 1 and a fixed seat 32 mounted on the upper surface of the adjustment seat 31. A locking groove 33 is provided on the fixed seat 32, and the fixed seat 32 can be adjusted in the vertical direction on the adjustment seat 31. The locking groove 33 can correspond to the position of the end of the test piece 100, and the end of the test piece 100 can be inserted into the locking groove 33 for positioning. A locking block 15 is detachably mounted on the fixed seat 32 by means of bolts. After the end of the test piece 100 is inserted into the locking groove 33, the locking block 15 can be pressed against the end of the test piece 100, thereby improving the positioning effect of the test piece 100.

[0041] A linear slide 19 is installed on the frame 1, and the lower surface of the adjustment seat 31 cooperates with the slide 19, so that the adjustment seat 31 is slidably installed on the frame 1. In order to ensure the stability of the adjustment seat 31 when sliding, two slides 19 are provided on the frame 1, and the adjustment seat 31 slides on the two slides 19. The cross section of the slide 19 can be a dovetail structure, so that the adjustment seat 31 slides on the slide 19 and is not easy to detach from the slide 19. The sliding of the adjustment seat 31 can also be achieved by a cylinder or other device.

[0042] Reference Figure 4 and Figure 5 The adjusting seat 31 is provided with a screw part 7 extending upward, and the screw part 7 is rotatably installed on the adjusting seat 31 by means of a bearing in an equal division. A horizontal plate 20 is fixed to the lower end of the fixing seat 32, and a screw sleeve 8 extending downward is fixed to the horizontal plate 20, and the screw part 7 is threadedly connected to the screw sleeve 8. A guide part 9 is also installed between the fixing seat 32 and the adjusting seat 31, and the guide part 9 can be used to limit the rotation of the fixing seat 32, so that the rotation of the screw part 7 can drive the fixing seat 32 to move upward or downward.

[0043] The guide part 9 includes a guide rod 91 mounted on the adjustment seat 31, and two guide rods 91 are provided and respectively located on both sides of the screw part 7.
