The ball grooves are located below the mounting grooves, and balls are rotatably installed in the ball grooves. One side of the ball protrudes from the ball groove, and when the electric roller is installed, the protruding side of the ball abuts against the end of the electric roller.

[0014] Preferably, the two support frames are respectively disposed on the two sliding grooves. The bottom of the support frame is slidably installed in the sliding groove via a slider. An arc-shaped groove is opened on the upper end of the support frame facing the electric roller to support the electric roller.

[0019] Compared with the prior art, the present invention provides an electric roller test frame and a testing method based on mechanical sensors, which has the following advantages:

[0020] 1. The electric roller test frame and the test method based on mechanical sensors, through the cooperation of the installation mechanism and support components, allow the electric roller to be installed on the test bench. First, the electric roller is supported by the support frame. Then, the movable frame of the installation mechanism moves towards the support frame, so that the shafts at both ends of the electric roller are placed on the fixed frame and the movable frame respectively. The electric roller that was supporting the electric roller moves away from the fixed frame, ending the support. The moving support frame drives the fixed plates on the fixed frame and the movable frame to move down through the main drive rod and the auxiliary drive rod respectively, so that the two fixed plates merge with the fixed frame and the movable frame respectively, thus quickly completing the installation of the electric roller. After the test is completed, the electric roller is quickly disassembled through the cooperation of the support frame and the movable frame, thereby improving the testing efficiency of the electric roller.

[0021] 2. The electric roller test frame and the test method based on mechanical sensors, through the setting of the ball bearings, ensure that the main body at both ends of the electric roller does not directly contact the fixed frame and the movable frame. When the electric roller drives the conveyor belt, it can reduce the resistance experienced by the electric roller and avoid affecting the test of the electric roller.

[0022] 3. The electric roller test frame and the test method based on mechanical sensors can simulate the scenario of the electric roller driving the conveyor belt to transport goods by setting up the detection components. With the cooperation of torque sensors, the working status of the electric roller can be monitored in real time, thereby obtaining accurate test results. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-8 An electric roller test frame includes a test bench 1, a mounting mechanism 2, a support assembly 3, and a test assembly 4. The mounting mechanism 2 includes a fixed frame 21, a movable frame 22, and a fixed plate 25. The fixed frame 21 and the movable frame 22 are respectively disposed at both ends of the test bench 1, and the movable frame 22 can slide towards the fixed frame 21. The upper ends of the fixed frame 21 and the movable frame 22 are slidably mounted with fixed plates 25.

[0034] The support assembly 3 includes a support frame 31, a main drive rod 33, and a secondary drive rod 34. The support frame 31 is slidably installed between the fixed frame 21 and the movable frame 22. The main drive rod 33 is installed on the outside of the support frame 31. One end of the main drive rod 33 cooperates with the fixed plate 25 on the fixed frame 21. The secondary drive rod 34 is slidably installed on the main drive rod 33, and one end of the secondary drive rod 34 extending out of the main drive rod 33 cooperates with the fixed plate 25 on the movable frame 22.

[0035] When the electric roller 5 is not installed, the two fixed plates 25 rise from the fixed frame 21 and the movable frame 22 respectively. When the electric roller 5 to be tested is placed on the support frame 31, the movable frame 22 drives the auxiliary drive rod 34 to move towards the fixed frame 21, so that the shafts at both ends of the electric roller 5 are placed on the fixed frame 21 and the movable frame 22 respectively. Then the support frame 31 moves away from the electric roller 5 to the outside of the test table 1, and drives the main drive rod 33 and the auxiliary drive rod 34 to drive the fixed plates 25 on the fixed frame 21 and the movable frame 22 to move down synchronously, clamping the shafts at both ends of the electric roller 5.

[0036] Test component 4 is set on the other side of the fixed frame 21 and connected to the shaft at the output end of the electric roller 5 under test, and is used to test the electric roller 5.

[0037] In use, the electric roller 5 to be tested must first be installed on the test bench 1. During this process, the movable frame 22 is initially positioned away from the support frame 31, ensuring sufficient space between the fixed frame 21 and the movable frame 22. The auxiliary drive rod 34 is then extended, and the two support frames 31 on the test bench 1 move closer together. Simultaneously, the fixed plates 25 on the fixed frame 21 and the movable frame 22 rise upwards. When installing the electric roller 5 to be tested, the shaft at the output end of the electric roller 5 is oriented towards the fixed frame 21 and placed on the support frame 31. The two close-to-each support frames 31 then... The support frame 31 aligns the shafts at both ends of the electric roller 5 with the fixed frame 21 and the movable frame 22, respectively. Then, the movable frame 22 moves towards the fixed frame 21, pushing the extended auxiliary drive rod 34 back into the main drive rod 33. After the shaft at one end of the electric roller 5 facing the movable frame 22 passes between the upper end of the movable frame 22 and its raised fixed plate 25, the movable frame 22 will contact the body of that end of the electric roller 5. The continuing movement of the movable frame 22 pushes the electric roller 5 on the support frame 31 towards the fixed frame 21, causing the shaft at the output end of the electric roller 5 to pass between the upper end of the fixed frame 21 and its raised fixed plate 25. The fixed plates 25 pass through each other, causing the body of the electric roller 5 at that end to abut against the fixed frame 21. Then, the two support frames 31 move away from each other and slide towards both sides of the test bench 1, ending the support for the electric roller 5. During this process, the moving support frame 31 synchronously drives the fixed plate 25 raised by the fixed frame 21 and the movable frame 22 downwards via the main drive rod 33 and the auxiliary drive rod 34, causing the two fixed plates 25 to merge with the fixed frame 21 and the movable frame 22 respectively, thereby installing the electric roller 5 onto the test bench 1. After the installation of the electric roller 5 is completed, the output shaft of the electric roller 5 is connected to the test bench 1. The test assembly 4 is connected, and then the electric roller 5 is operated. The electric roller 5 is tested by the test assembly 4. After the test is completed, the two support frames 31 move closer to each other again to support the electric roller 5. The main drive rod 33 and the auxiliary drive rod 34 synchronously drive the fixed plate 25 on the fixed frame 21 and the movable frame 22 to rise again. Then the movable frame 22 moves away from the support frame 31, thereby releasing the electric roller 5. After the staff disconnects the electric roller 5 from the test assembly 4, the tested electric roller 5 can be taken out, thereby improving the loading and unloading speed of the electric roller 5 under test.

[0038] Furthermore, the test bench 1 is provided with a sliding groove 11 and a moving groove 12 in sequence. The two sliding grooves 11 are located between the fixed frame 21 and the moving groove 12, and the two sliding grooves 11 are symmetrically distributed on both sides of the moving groove 12.

[0039] Furthermore, the fixed frame 21 is fixedly installed on the test bench 1, and the bottom of the movable frame 22 is fixedly connected to the drive block 221. The fixed frame 21 and the movable frame 22 are provided with mounting grooves 23 on both sides. The mounting grooves 23 are matched with the shafts at both ends of the electric roller 5. The fixed frame 21 and the movable frame 22 are provided with drive grooves 24 on both sides. The two drive grooves 24 are located on both sides of the mounting grooves 23 respectively. The bottom of the fixed plate 25 is fixedly connected to both sides of the pull rod 251. The pull rod 251 is slidably installed in the drive groove 24. The drive rack 252 is fixedly installed on the pull rod 251.

[0040] During the movement of the movable frame 22 toward the fixed frame 21, the shafts at both ends of the electric roller 5 are respectively placed in the mounting slots 23 on the fixed frame 21 and the movable frame 22. When the support frame 31 releases its support for the electric roller 5, the support frame 31 synchronously drives the pull rods 251 under the two fixed plates 25 through the main drive rod 33 and the auxiliary drive rod 34, causing the pull rods 251 to move toward the bottom of the drive slot 24, thereby pulling the two fixed plates 25 together with the movable frame 22 and the fixed frame 21 respectively. When the support frame 31 supports the electric roller 5, the support frame 31 synchronously drives the pull rods 251 under the two fixed plates 25 through the main drive rod 33 and the auxiliary drive rod 34, causing the pull rods 251 to move toward the upper end of the drive slot 24, thereby pushing the two fixed plates 25 that are respectively merged on the fixed frame 21 and the movable frame 22 to rise upward, thereby opening the mounting slot 23 and allowing the electric roller 5 to be removed.

[0041] Furthermore, a transmission rod 26 is rotatably mounted on the side of the fixed frame 21 and the movable frame 22 away from the electric roller 5. Each drive slot 24 corresponds to a transmission rod 26. A drive gear 261 is coaxially fixedly connected to the end of the transmission rod 26 located inside the drive slot 24. The drive gear 261 meshes with the drive rack 252. A driven gear 262 is coaxially fixedly connected to the end of the transmission rod 26 located outside the drive slot 24. A slide rail 27 is also fixedly mounted on the side of the fixed frame 21 and the movable frame 22 away from the electric roller 5. The slide rail 27 is located below the driven gear 262.

[0042] When the support frame 31 releases its support from the electric roller 5, the main drive rod 33 and the auxiliary drive rod 34 on the support frame 31 synchronously drive the transmission rod 26 on the fixed frame 21 and the movable frame 22 to rotate in opposite directions. The rotating transmission rod 26 drives the drive rack 252 through the drive gear 261 to move the pull rod 251 to the bottom of the drive groove 24. When the support frame 31 supports the electric roller 5, the main drive rod 33 and the auxiliary drive rod 34 on the support frame 31 synchronously drive the transmission rod 26 on the fixed frame 21 and the movable frame 22 to rotate in the forward direction. The rotating transmission rod 26 drives the drive rack 252 through the drive gear 261 to move the pull rod 251 to the upper end of the drive groove 24.

[0043] Furthermore, the mounting mechanism 2 also includes a servo motor 28, which is fixedly installed in the end of the moving groove 12 away from the fixed frame 21. The output shaft of the servo motor 28 is coaxially fixedly connected to one end of the lead screw 281, and the other end of the lead screw 281 is rotatably connected to the other end of the moving groove 12. The drive block 221 is threaded onto the lead screw 281.

[0044] When installing the electric roller 5, the servo motor 28 drives the lead screw 281 to rotate in the forward direction, and drives the movable frame 22 to move towards the support frame 31 through the drive block 221. When disassembling the electric roller 5, the servo motor 28 drives the lead screw 281 to rotate in the reverse direction, and drives the movable frame 22 away from the support frame 31 through the drive block 221.

[0045] Furthermore, both the fixed frame 21 and the movable frame 22 have ball grooves 29 on the side facing the end of the electric roller 5. The ball grooves 29 are located below the mounting groove 23. A ball 291 is rotatably installed in the ball grooves 29. One side of the ball 291 protrudes from the ball grooves 29. When the electric roller 5 is installed, the protruding side of the ball 291 abuts against the end of the electric roller 5.

[0046] When the shafts at both ends of the electric roller 5 are respectively mounted on the fixed frame 21 and the movable frame 22, the bodies at both ends of the electric roller 5 abut against the protruding balls 291 on the sides of the fixed frame 21 and the movable frame 22, thereby avoiding direct contact between the electric roller 5 body and the fixed frame 21 and the movable frame 22 and reducing the friction force when the electric roller 5 is in operation.

[0047] Furthermore, two support frames 31 are respectively set on two sliding grooves 11. The bottom of the support frame 31 is slidably installed in the sliding groove 11 by a slider. The upper end of the support frame 31 facing the electric roller 5 has an arc-shaped groove for supporting the electric roller 5. The bottom of the support frame 31 is fixedly connected to the output shaft of the cylinder 32. The cylinder 32 is fixedly installed on the test bench 1. The main drive rod 33 is fixedly installed on the side of the support frame 31 away from the electric roller 5. One end of the main drive rod 33 extends to the side of the fixed frame 21 away from the electric roller 5. The extended end of the auxiliary drive rod 34 extends to the side of the movable frame 22 away from the electric roller 5. A driven rack 35 is fixedly connected to the extended ends of the main drive rod 33 and the auxiliary drive rod 34. The driven rack 35 is slidably installed in the slide rail 27 and meshes with the driven gear 262.

[0048] Initially, two cylinders 32 distributed on both sides of the moving groove 12 simultaneously extend their output shafts, pushing two support frames 31 to move closer together, so that the moving support frames 31 support the electric roller 5. At the same time, the moving support frames 31 drive the main drive rod 33 and the auxiliary drive rod 34 on them to move towards the moving groove 12, thereby pushing the driven rack 35 to move in the same direction within the slide rail 27. The moving driven rack 35 drives the driven gear 262 to drive the transmission rod 26 to rotate in the forward direction. When the support frames 31 release the support of the electric roller 5, the two cylinders 32 simultaneously retract their output shafts, pulling the two support frames 31 away from each other. At the same time, the moving support frames 31 drive the main drive rod 33 and the auxiliary drive rod 34 on them to move away from the moving groove 12, thereby pulling the driven rack 35 to move in the same direction within the slide rail 27. The moving driven rack 35 drives the driven gear 262 to drive the transmission rod 26 to rotate in the reverse direction.

[0049] Furthermore, the test assembly 4 includes a mounting bracket 41, a conveyor belt 42, and a counterweight plate 43. The mounting bracket 41 is fixedly mounted on the test bench 1, and the mounting bracket 41 is located on the side of the fixed frame 21 away from the movable frame 22. The conveyor belt 42 is rotatably connected to the mounting bracket 41, and the counterweight plate 43 is fixedly connected to the conveyor belt 42. A weight is placed in the counterweight plate 43. After the electric roller 5 is installed on the test bench 1, the output shaft of the electric roller 5 is fixedly connected to the first roller on the end of the conveyor belt 42 near the fixed frame 21.

[0050] After the electric roller 5 is installed, the output shaft of the electric roller 5 is connected to the first rotating roller at the end of the conveyor belt 42 near the fixed frame 21. During the test, the electric roller 5 drives the conveyor belt 42 to rotate through the rotating roller connected to it. With the cooperation of the counterweight plate 43 with heavy objects, the electric roller 5 drives the conveyor belt 42 to transport goods, thereby testing the electric roller 5.

[0051] Furthermore, the test assembly 4 also includes a torque sensor 44. After the electric roller 5 is installed, the torque sensor 44 is fixedly installed on the output end of the electric roller 5 to detect the motion state of the electric roller 5.

[0052] During the operation of the electric roller 5 driving the conveyor belt 42, the torque sensor 44 converts the physical changes in torque into precise electrical signals, thereby monitoring the operating status of the electric roller 5 in real time.

[0053] This invention also provides a testing method based on mechanical sensors, using an electric roller test frame, the specific steps of which are as follows:

[0054] First, the output shaft of the electric roller 5 to be tested is oriented towards the fixed frame 21 and placed on the closed support frame 31. Then, the movable frame 22 of the mounting mechanism 2 moves towards the fixed frame 21, so that both ends of the electric roller 5 are placed on the fixed frame 21 and the movable frame 22 respectively. At this time, the closed support frame 31 separates, ending the support for the electric roller 5. The two raised fixed plates 25 are driven to move down synchronously through the main drive rod 33 and the auxiliary drive rod 34, and merge with the fixed frame 21 and the movable frame 22 respectively, thereby quickly completing the installation of the electric roller 5 and connecting the output shaft of the electric roller 5 with the test component 4 on the test bench 1 for testing.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
